The Offering

This prospectus covers 13,801,119 shares of stock, all of which are offered for sale by the selling stockholders.

Vista Capital Transaction

On December 18, 2017, we received $495,000 pursuant to a securities purchase agreement (the “Vista Agreement”) and a registration rights agreement (the “Vista RRA”) with Vista Capital and issued a convertible note (the “Vista Note”) to Vista Capital in the aggregate principal amount of $500,000 at 5% annual interest, which was initially convertible into shares of common stock of the Company at $0.394 per share, subject to the terms, and certain limitations and conditions, set forth in the Vista Agreement and Vista Note. The Vista Note was initially scheduled to mature on September 18, 2018. As set forth below, the Vista Note has been partially paid and the maturity date of the remaining principle amount has been extended.

Pursuant to the Vista Agreement, the Company issued 250,000 shares of common stock to Vista Capital as a commitment fee (the “Vista Commitment Shares”).

Under the Vista Note and Vista Agreement, the Company initially reserved 1,316,668 shares of common stock for issuance upon conversion of the Vista Note. Pursuant to the Vista RRA, we agreed and filed a registration statement with the Securities and Exchange Commission (the “SEC”) registering the 1,316,668 shares of common stock for conversion of the Vista Note, as well as the 250,000 Vista Commitment Shares. The Vista Agreement required the issuance of additional Vista Commitment Shares in the event the closing price of our common stock, on the earlier of the date the registration statement is deemed effective and 20 trading days following the six-month anniversary of the Vista Note, is lower than the closing price on December 18, 2017 (which was $0.41). On the effective date of the Registration Statement (February 8, 2018), the closing price of the Company’s common stock was $0.3147 per share. As a result, in February 2018, the Company issued 140,849 additional commitment shares to Vista Capital.

Vista Capital represented to the Company, among other things, that it was an “accredited investor” (as such term is defined in Rule 501(a) of Regulation D under the Securities Act of 1933, as amended). The Vista Note, the Vista Agreement, and the Vista RRA contain customary representations, warranties, agreements and conditions including indemnification rights and obligations of the parties.

The Company used the proceeds received by the Company of the Vista Note for working capital and general corporate purposes.

See “Subsequent Conversions of Vista Note, Changes to Conversion Price”, below.

FirstFire Transaction

On January 16, 2018, we entered into a securities purchase agreement (the “FirstFire Agreement”) and a registration rights agreement (the “FirstFire RRA”) with FirstFire.

In conjunction with the execution of the FirstFire Agreement, and receipt of funds, we issued a convertible promissory note (the “FirstFire Note”) to FirstFire in the aggregate principal amount of $150,000 at 5% annual interest, which was initially convertible into shares of common stock of the Company at $0.394 per share, subject to the terms, and certain limitations and conditions, set forth in the FirstFire Agreement and the FirstFire Note. FirstFire may convert the FirstFire Note at any time. The Company may require the conversion of the FirstFire Note in the event the Company’s common stock has traded at a price per share of $0.75 or above for the ten trading days immediately preceding the mandatory conversion, and the shares underlying the conversion are subject to an effective registration statement filed with the SEC. The FirstFire Note has been paid in full and would have matured on October 16, 2018.

Pursuant to the FirstFire Agreement, the Company issued 75,000 shares of common stock to FirstFire (the “FirstFire Commitment Shares”) as a commitment fee.

Under the FirstFire Note, the Company initially reserved 394,949 shares of common stock for issuance upon its conversion. Pursuant to the FirstFire RRA, we agreed to file a registration statement with the SEC registering all shares of common stock into which the FirstFire Note is convertible and the FirstFire Commitment Shares. The FirstFire Agreement required the issuance of additional FirstFire Commitment Shares in the event the closing price of our common stock, on the earlier of the date the registration statement is deemed effective and 20 trading days following the six-month anniversary of the FirstFire Note, is lower than the closing price on January 16, 2018. On February 8, 2018, the closing price of the Company’s common stock was $0.3147 per share. As a result, in February 2018, the Company issued 36,536 additional commitment shares to FirstFire.

Table of Contents

FirstFire represented to the Company, among other things, that it was an “accredited investor” (as such term is defined in Rule 501(a) of Regulation D under the Securities Act of 1933, as amended). The FirstFire Note, the FirstFire Agreement, and the FirstFire RRA contain customary representations, warranties, agreements and conditions including indemnification rights and obligations of the parties.

The Company used the proceeds received by the Company of the FirstFire Note for working capital and general corporate purposes.

In June 2018, FirstFire elected to convert $95,761 of the outstanding principal balance of the FirstFire Note and we issued 383,047 shares. In July 2018, FirstFire elected to convert the remaining principal due on the note of $54,239. We issued an aggregate 217,960 shares at $0.25 per share, consisting of 216,950 shares for payment of principal, and 1,010 for payment of accrued interest. As of the date of this Prospectus, the FirstFire Note is paid in full.

Black Mountain and Gemini Transaction dated July 8, 2016

On July 8, 2016, we received $250,000 and issued convertible promissory notes (initially convertible at $0.45 per share) with a maturity date of July 8, 2017 to Black Mountain and Gemini in the aggregate principal amount of $280,000. Interest was charged upon issuance at 3% per annum. Concurrently, we issued these investors stock purchase warrants to purchase an aggregate 400,000 shares of our common stock, initially exercisable at $0.65 per share, which expire five years from the date of grant. Subject to certain exceptions, the exercise price of the stock purchase warrant may be adjusted downward in the event we sell our common stock or issue warrants at a lower price. Both Black Mountain and Gemini exercised their rights to convert their promissory notes to common stock, and on January 17, 2017, we issued an aggregate 640,889 shares in full payment of principal and interest due under the notes.

These warrants issued to Black Mountain and Gemini have since been repriced pursuant their terms (see “Warrant Reprice” below).

Black Mountain and Gemini Transaction dated December 30, 2016

On December 30, 2016, we received $250,000 and issued convertible promissory notes (initially convertible at $0.57 per share) with a maturity date of December 30, 2017 to Black Mountain and Gemini in the aggregate principal amount of $280,000. Interest was charged upon issuance at 3% per annum. Concurrently, we issued these investors stock purchase warrants to purchase an aggregate 400,000 shares of our common stock, initially exercisable at $0.75 per share, which expire five years from the date of grant. Subject to certain exceptions, the exercise price of the stock purchase warrant may be adjusted downward in the event we sell our common stock or issue warrants at a lower price. Both Black Mountain and Gemini exercised their rights to convert their promissory notes to common stock, and on July 20, 2017, we issued an aggregate 686,667 shares in full payment of principal and interest due under the notes.

These warrants issued to Black Mountain and Gemini have since been repriced pursuant their terms (see “Warrant Reprice” below).

Black Mountain and Gemini Transaction dated July 18, 2017

On July 18, 2017, we received $250,000 and issued convertible promissory notes (initially convertible at $0.42 per share) with a maturity date of July 8, 2018 to Black Mountain and Gemini in the aggregate principal amount of $280,000. Interest was charged upon issuance at 3% per annum. Concurrently, we issued these investors stock purchase warrants to purchase an aggregate 400,000 shares of our common stock, initially exercisable at $0.65 per share, which expire five years from the date of grant. Subject to certain exceptions, the exercise price of the stock purchase warrant may be adjusted downward in the event we sell our common stock or issue warrants at a lower price.

These warrants issued to Black Mountain and Gemini have since been repriced pursuant their terms (see “Warrant Reprice” below).

Warrant Reprice

Subsequent to the issuance of the warrants to Black Mountain and Gemini, we sold shares of our common stock at a price lower than the exercise price of the warrants. Pursuant to the terms of those warrants, the exercise price automatically reduced to the lowest price that we sold our shares, and the number of shares exercisable under the warrants increased such that the dollar amount required to fully exercise each warrant remained the same. Thus, for example, in July 2016 we issued warrants to purchase an aggregate 400,000 shares to Black Mountain and Gemini, exercisable at $0.65 per share. To purchase the 400,000 shares at $0.65 would require $260,000, payable to BioLargo. In February 2018, the exercise price of these warrants was reduced to $0.25 per share, and the number of shares issuable by BioLargo upon exercise of these warrants has been increased from 400,000 to 1,040,000. On March 30, 2019, we again notified Black Mountain and Gemini that we sold shares at a lower price than the $0.25 exercise price in the warrants, and issued notices that the exercise price of the warrants issued in July 2016 and December 2016 had decreased to $0.12 a share. ¹

¹	The July 2017 warrants contain an exemption for shares issued in conversion of promissory notes, and thus the exercise price of the July 2017 warrants did not adjust.

Table of Contents

In the aggregate, the warrants originally issued to Black Mountain and Gemini provided for the purchase of 1,200,000 shares. Because the subsequent exercise price reductions, the number of shares purchasable under the warrants has increased to an aggregate of 5,706,666 shares.

As of May 10, 2019, there were 144,953,058 shares of our common stock outstanding, of which 106,447,090 shares were held by non-affiliates. If all of the 13,801,119 shares offered by the selling stockholders under this prospectus were issued and outstanding as of the date hereof, such shares would represent 7.7% of the total number of shares of our common stock outstanding and 10.2% of the total number of outstanding shares held by non-affiliates, in each case as of the date hereof.

Issuances of our common stock in this offering will not affect the rights or privileges of our existing stockholders, except that the economic and voting interests of each of our existing stockholders will be diluted as a result of any such issuance. Although the number of shares of common stock that our existing stockholders own will not decrease, the shares owned by our existing stockholders will represent a smaller percentage of our total outstanding shares after any such issuance to Vista Capital, Black Mountain, or Gemini.

Subsequent Conversions of Vista Note, Changes to Conversion Price

Subsequent to the filing of the Registration Statement, in February 2018, the conversion rate of the Vista Note was reduced to $0.25 pursuant to the price protection features in the Note.

In June 2018, Vista Capital elected to convert $52,025 of the outstanding principal balance of the Vista Note and we issued 208,100 shares, plus shares for interest that had accrued through the date of conversion. As of June 30, 2018, the outstanding balance on the Vista Note was $447,975. Through the September 18, 2018 maturity date, the note would have accrued additional interest, such that the amount due on the date of maturity would be $453,140.

On August 28, 2018, we filed Amendment No. 1 to the Registration Statement. At that time, we determined that the principal and interest due on the Vista Note at the September 18, 2018 maturity date would be $453,140. Therefore, Amendment No. 1 increased to 1,812,561 the shares registered to Vista Capital for conversion of the Vista Note.

On September 12, 2018, Vista Capital agreed to extend the maturity date of the Vista Note to December 18, 2018.  In return, we increased the principal outstanding balance by 20% or $92,000. In addition, we issued Vista Capital a warrant to purchase 1,812,000 shares of our common stock at $0.25 per share.

On December 18, 2018, Vista Capital elected to convert $166,667 of the outstanding principal and interest of the Vista Note in conjunction with our agreement that the principal amount of the note had increased by $166,667 in accordance with the price protection features in the Vista Note and our issuance of a promissory note dated October 16, 2018 that contained an original issue discount. We issued Vista Capital 666,668 shares of our common stock as a result of this conversion. As of December 31, 2018, the outstanding balance on the Vista Note totaled $550,000.

On January 7, 2019, Vista Capital agreed to extend the maturity date of the Vista Note to April 15, 2019. We agreed to amend the note to (i) increase the principal amount of the note to $605,100, (ii) re-define the conversion price of the note to equal 80% of the lowest closing bid price of the Company’s common stock during the 25 consecutive trading days immediately preceding the conversion date, (iii) reduce the prepayment penalty from 20% to 15%, such that a prepayment requires the payment of an additional 15% of the then outstanding balance, and (iv) reduce the penalty for a default from 30% to 25% of the outstanding balance.

Subsequent to the January 7, 2019 amendment, Vista Capital has chosen to convert $275,000 of the Vista 2017 Note (credited to interest and then principal), and received an aggregate 2,158,353 shares of our common stock. We and Vista Capital have agreed to further extend the maturity date from April 15, 2019 to July 15, 2019, and as consideration have increased the principal balance of the note by 10%. Accounting for these conversions and the extension, the principal amount due on the note is $370,451.

RISK FACTORS

An investment in our common stock is highly speculative, involves a high degree of risk and should be made only by investors who can afford a complete loss. You should carefully consider the following risk factors, together with the other information in this prospectus, including our financial statements and the related notes, before you decide to buy our common stock. If any of the following risks actually occur s , then our business, financial condition or results of operations could be materially adversely affected, the trading of our common stock could decline, and you may lose all or part of your investment therein.

Risks Relating to our Business

Our limited operating history makes evaluation of our business difficult.

We have limited and only nominal historical financial data upon which to base planned operating expenses or forecast accurately our future operating results. Because our operations are not yet sufficient to fund our operational expenses, we rely on investor capital to fund operations. Our limited operational history make it difficult to forecast the need for future financing activities. Further, our limited operating history will make it difficult for investors and securities analysts to evaluate our business and prospects. Our failure to address these risks and difficulties successfully could seriously harm us.

We have never generated any significant revenues, have a history of losses, and cannot assure you that we will ever become or remain profitable.

We have not yet generated any significant revenue from operations, and, accordingly, we have incurred net losses every year since our inception. To date, we have dedicated most of our financial resources to research and development, general and administrative expenses, and initial sales and marketing activities. We have funded the majority of our activities through the issuance of convertible debt or equity securities. Although sale of our CupriDyne Clean products are increasing, and we are devoting more energy and money to our sales and marketing activities, we continue to anticipate net losses and negative cash flow for the foreseeable future. Our ability to reach positive cash flow depends on many factors, including our ability to fund sales and marketing activities, and the rate of client adoption. There can be no assurance that our revenues will be sufficient for us to become profitable in 2019 or future years, or thereafter maintain profitability. We may also face unforeseen problems, difficulties, expenses or delays in implementing our business plan, including generally the need for odor control products in solid waste handling operations, which we may not fully understand or be able to predict.

Our cash requirements are significant. We will require additional financing to sustain our operations and without it we may not be able to continue operations.

Our cash requirements and expenses will continue to be significant. Our net cash used in continuing operations for the year ended December 31, 2018 was almost $4,000,000, over $300,000 per month. During that same period, we generated only $1,364,000 in total gross revenues. Thus, in order to become profitable, we must significantly increase our revenues. Although our revenues are increasing through sales of our products and from our engineering division, we expect to continue to use cash in 2019 as it becomes available.

At December 31, 2018, we had working capital deficit of approximately $1,536,000. Our auditor’s report for the year ended December 31, 2018 includes an explanatory paragraph to their audit opinion stating that our recurring losses from operations and working capital deficiency raise substantial doubt about our ability to continue as a going concern. We do not currently have sufficient financial resources to fund our operations or those of our subsidiaries. Therefore, we need additional financing to continue these operations.

In August 2017, we entered into a three-year purchase agreement with Lincoln Park Capital Fund LLC (“Lincoln Park”) through which we may direct Lincoln Park to purchase shares of our common stock at prices that depend on the market price of our stock (the “LPC Agreement”). Over time, and subject to multiple limitations, we may direct Lincoln Park to purchase up to $10,000,000 of our common stock. Since inception of the LPC Agreement, through December 31, 2018, we directed Lincoln Park to purchase 4,025,733 shares of our common stock, and received $1,349,969 in proceeds. During the year ended December 31, 2018, we directed Lincoln Park to purchase 2,850,733 shares of our common stock, and received $838,884 in proceeds. The extent to which we rely on Lincoln Park as a source of funding in 2019 will depend on a number of factors, including the prevailing market price of our common stock, and the extent to which we are able to secure working capital from other sources. If obtaining sufficient funding from Lincoln Park were to prove unavailable or prohibitively dilutive, we will need to secure another source of funding in order to satisfy our working capital needs. Even if we were receive the full maximum commitment of $10,000,000 in aggregate gross proceeds from sales of our common stock to Lincoln Park during the three year term of the LPC Agreement, we may still need additional capital to fully implement our business, operating and development plans. Should the financing we require to sustain our working capital needs be unavailable or prohibitively expensive when we require it, the consequences could be a material adverse effect on our business, operating results, financial condition and prospects.

Table of Contents

From time to time, we issue stock, instead of cash, to pay some of our operating expenses. These issuances are dilutive to our existing stockholders.

We are party to agreements that provide for the payment of, or permit us to pay at our option, securities rather than cash in consideration for services provided to us. We include these provisions in agreements to allow us to preserve cash. When we pay employees, vendors and consultants in stock or stock options, we do so at a premium. We anticipate that we will continue to do so in the future. All such issuances are dilutive to our stockholders because they increase (and will increase in the future) the total number of shares of our common stock issued and outstanding, even though such arrangements assist us with managing our cash flow. These issuances also increase the expense amount recorded.

Our stockholders face further potential dilution in any new financing.

Our private securities offerings typically provide for convertible securities, including notes and warrants. Any additional capital that we raise would dilute the interest of the current stockholders and any persons who may become stockholders before such financing. Given the low price of our common stock, such dilution in any financing of a significant amount could be substantial.

Our stockholders face further potential adverse effects from the terms of any preferred stock that may be issued in the future.

In order to raise capital to meet expenses or to acquire a business, our board of directors may issue additional stock, including preferred stock. Any preferred stock that we may issue may have voting rights, liquidation preferences, redemption rights and other rights, preferences and privileges. The rights of the holders of our common stock will be subject to, and in many respects subordinate to, the rights of the holders of any such preferred stock. Furthermore, such preferred stock may have other rights, including economic rights, senior to our common stock that could have a material adverse effect on the value of our common stock. Preferred stock, while providing desirable flexibility in connection with possible acquisitions and other corporate purposes, can also have the effect of making it more difficult for a third party to acquire a majority of our outstanding voting stock, thereby delaying, deferring or preventing a change in control of our company.

There are several specific business opportunities we are considering in further development of our business. None of these opportunities is yet the subject of a definitive agreement, and most or all of these opportunities will require additional funding obligations on our part, for which funding is not currently in place.

In furtherance of our business plan, we are presently considering a number of opportunities to promote our business, to further develop and broaden, and to license, our technology with third parties. While discussions are underway with respect to such opportunities, there are no definitive agreements in place with respect to any of such opportunities at this time. There can be no assurance that any of such opportunities being discussed will result in definitive agreements or, if definitive agreements are entered into, that they will be on terms that are favorable to us.

Moreover, should any of these opportunities result in definitive agreements being executed or consummated, we may be required to expend additional monies above and beyond our current operating budget to promote such endeavors. No such financing is in place at this time for such endeavors, and we cannot assure you that any such financing will be available, or if it is available, whether it will be on terms that are favorable to our company.

We expect to incur future losses and may not be able to achieve profitability.

Although we are generating limited revenue from the sale of our products, and we expect to generate revenue from new products we are introducing, and eventually from other license or supply agreements, we anticipate net losses and negative cash flow to continue for the foreseeable future until our products are expanded in the marketplace and they gain broader acceptance by resellers and customers. Our current level of sales is not sufficient to support the financial needs of our business. We cannot predict when or if sales volumes will be sufficiently large to cover our operating expenses. We intend to expand our marketing efforts of our products as financial resources are available, and we intend to continue to expand our research and development efforts. Consequently, we will need to generate significant additional revenue or seek additional financings to fund our operations. This has put a proportionate corresponding demand on capital. Our ability to achieve profitability is dependent upon our efforts to deliver a viable product and our ability to successfully bring it to market, which we are currently pursuing. Although our management is optimistic that we will succeed in licensing our technology, we cannot be certain as to timing or whether we will generate sufficient revenue to be able to operate profitably. If we cannot achieve or sustain profitability, then we may not be able to fund our expected cash needs or continue our operations. If we are not able to devote adequate resources to promote commercialization of our technology, then our business plans will suffer and may fail.

Table of Contents

Because we have limited resources to devote to sales, marketing and licensing efforts with respect to our technology, any delay in such efforts may jeopardize future research and development of technologies and commercialization of our technology. Although our management believes that it can finance commercialization efforts through sales of our securities and possibly other capital sources, if we do not successfully bring our technology to market, our ability to generate revenues will be adversely affected.

Our internal controls are not effective.

We have determined that our disclosure controls and procedures and our internal control over financial reporting are currently not effective. The lack of effective internal controls could materially adversely affect our financial condition and ability to carry out our business plan.

Our management team for financial reporting, under the supervision and with the participation of our chief executive officer and our chief financial officer, conducted an evaluation of the effectiveness of the design and operation of our internal controls. Recognizing the dynamic nature and growth of the Company’s business in the year ended December 31, 2018, including the growth of the core operations and the increase in the number of employees, management has recognized the strain on the overall internal control environment. As a result, management has concluded that its internal controls over financial reporting are not effective. Management identified a material weakness with respect to deficiencies in its financial closing and reporting procedures. Management believes this is due to a lack of resources. Management intends to add accounting personnel and operating staff and more sophisticated systems in order to improve its reporting procedures and internal controls, subject to available capital. Until we have adequate resources to increase address these issues, any material weaknesses may materially adversely affect our ability to report accurately our financial condition and results of operations in the future in a timely and reliable manner. In addition, although we continually review and evaluate internal control systems to allow management to report on the sufficiency of our internal controls, we cannot assure you that we will not discover additional weaknesses in our internal control over financial reporting. Any such additional weakness or failure to remediate the existing weakness could materially adversely affect our financial condition or ability to comply with applicable financial reporting requirements and the requirements of the Company’s various financing agreements.

If we are not able to manage our anticipated growth effectively, we may not become profitable.

We anticipate that expansion will continue to be required to address potential market opportunities for our technology and our products. Our existing infrastructure is limited. While we believe our current manufacturing processes as well as our office and warehousing provide the basic resources to expand as we grow sales of CupriDyne Clean to more than $2 million per month, our infrastructure will need more staffing to support manufacturing, customer service, administration as well as sales/account executive functions. There can be no assurance that we will have the financial resources to create new infrastructure, or that any such infrastructure will be sufficiently scalable to manage future growth, if any. There also can be no assurance that, if we invest in additional infrastructure, we will be effective in expanding our operations or that our systems, procedures or controls will be adequate to support such expansion. In addition, we will need to provide additional sales and support services to our partners if we achieve our anticipated growth with respect to the sale of our technology for various applications. Failure to properly manage an increase in customer demands could result in a material adverse effect on customer satisfaction, our ability to meet our contractual obligations, and our operating results.

Some of the products incorporating our technology will require regulatory approval.

The products in which our technology may be incorporated have both regulated and non-regulated applications. The regulatory approvals for certain applications may be difficult, impossible, time consuming and/or expensive to obtain. While our management believes such approvals can be obtained for the applications contemplated, until those approvals from the FDA or the EPA or other regulatory bodies, at the federal and state levels, as may be required are obtained, we may not be able to generate commercial revenues for regulated products. Certain specific regulated applications and their use require highly technical analysis and additional third-party validation and will require regulatory approvals from organizations like the FDA. Certain applications may also be subject to additional state and local agency regulations, increasing the cost and time associated with commercial strategies. Additionally, most products incorporating our technology that may be sold in the European Union (“EU”) will require EU and possibly also individual country regulatory approval. All such approvals, including additional testing, are time-consuming, expensive and do not have assured outcomes of ultimate regulatory approval.

We need to outsource and rely on third parties for the manufacture of the chemicals, material components or delivery apparatus used in our technology, and part of our future success will be dependent on the timeliness and effectiveness of the efforts of these third parties.

We do not have the required financial and human resources or capability to manufacture the chemicals necessary to make our odor control products. Our business model calls for the outsourcing of the manufacture of these chemicals in order to reduce our capital and infrastructure costs as a means of potentially improving our financial position and the profitability of our business. Accordingly, we must enter agreements with other companies that can assist us and provide certain capabilities, including sourcing and manufacturing, which we do not possess. We may not be successful in entering into such alliances on favorable terms or at all. Even if we do succeed in securing such agreements, we may not be able to maintain them. Furthermore, any delay in entering into agreements could delay the development and commercialization of our technology or reduce its competitiveness even if it reaches the market. Any such delay related to such future agreements could adversely affect our business.

If any party to which we have outsourced certain functions fails to perform its obligations under agreements with us, the commercialization of our technology could be delayed or curtailed.

To the extent that we rely on other companies to manufacture the chemicals used in our technology, or sell or market products incorporating our technology, we will be dependent on the timeliness and effectiveness of their efforts. If any of these parties does not perform its obligations in a timely and effective manner, the commercialization of our technology could be delayed or curtailed because we may not have sufficient financial resources or capabilities to continue such efforts on our own.

We rely on a small number of key supply ingredients in order to manufacture our products.

All of the supply ingredients used to manufacture our products are readily available from multiple suppliers. However, commodity prices for these ingredients can vary significantly, and the margins that we are able to generate could decline if prices rise. If our manufacturing costs rise significantly, we may be forced to raise the prices for our products, which may reduce their acceptance in the marketplace.

If our technology or products incorporating our technology do not gain market acceptance, it is unlikely that we will become profitable.

The potential markets for products into which our technology can be incorporated are rapidly evolving, and we have many successful competitors including some of the largest and most well-established companies in the world. (see, herein: “Description At this time, our technology is unproven in all but one industry – waste management – and the use of our technology by others, and the sales of our products, is relatively nominal. The commercial success of products incorporating our technology will depend on the adoption of our technology by commercial and consumer end users in various fields.

Market acceptance may depend on many factors, including:

●

the willingness and ability of consumers and industry partners to adopt new technologies from a company with little or no history in the industry;

●

our ability to convince potential industry partners and consumers that our technology is an attractive alternative to other competing technologies;

●

our ability to license our technology in a commercially effective manner;

●

our ability to continue to fund operations while our products move through the process of gaining acceptance, before the time in which we are able to scale up production to obtain economies of scale; and

●

our ability to overcome brand loyalties.

If products incorporating our technology do not achieve a significant level of market acceptance, then demand for our technology itself may not develop as expected, and, in such event, it is unlikely that we will become profitable.

Table of Contents

Any revenues that we may earn in the future are unpredictable, and our operating results are likely to fluctuate from quarter to quarter.

We believe that our future operating results will fluctuate due to a variety of factors, including:

●

delays in product development by us or third parties;

●

market acceptance of products incorporating our technology;

●

changes in the demand for, and pricing of, products incorporating our technology;

●

competition and pricing pressure from competitive products; and

●

expenses related to, and the results of, proceedings relating to our intellectual property.

We expect our operating expenses will continue to fluctuate significantly in 2019 and beyond, as we continue our research and development and increase our marketing and licensing activities. Although we expect to generate revenues from licensing our technology in the future, revenues may decline or not grow as anticipated, and our operating results could be substantially harmed for a particular fiscal period. Moreover, our operating results in some quarters may not meet the expectations of stock market analysts and investors. In that case, our stock price most likely would decline.

Some of our revenue is dependent on the award of new contracts from the U.S. government, which we do not directly control.

A substantial portion of our revenue and is generated from sales to the U.S. defense logistics agency through a bid process in response to request for bids. The timing and size of requests for bids is unpredictable and outside of our control. The number of other companies competing for these bids is also unpredictable and outside of our control. In the event of more competition for these awards, we may have to reduce our margins. These variables make it difficult to predict when or if we will sell more products to the US government, which in turns makes it difficult to stock inventory and purchase raw materials.

We have limited product distribution experience, and we rely in part on third parties who may not successfully sell our products.

We have limited product distribution experience and rely in part on product distribution arrangements with third parties. In our future product offerings, we may rely solely on third parties for product sales and distribution. We also plan to license our technology to certain third parties for commercialization of certain applications. We expect to enter into additional distribution agreements and licensing agreements in the future, and we may not be able to enter into these additional agreements on terms that are favorable to us, if at all. In addition, we may have limited or no control over the distribution activities of these third parties. These third parties could sell competing products and may devote insufficient sales efforts to our products. As a result, our future revenues from sales of our products, if any, will depend on the success of the efforts of these third parties.

We may not be able to attract or retain qualified senior personnel.

We believe we are currently able to manage our current business with our existing management team. However, as we expand the scope of our operations, we will need to obtain the full-time services of additional senior management and other personnel. Competition for highly-skilled personnel is intense, and there can be no assurance that we will be able to attract or retain qualified senior personnel. Our failure to do so could have an adverse effect on our ability to implement our business plan. As we add full-time senior personnel, our overhead expenses for salaries and related items will increase from current levels and, depending upon the number of personnel we hire and their compensation packages, these increases could be substantial.

If we lose our key personnel or are unable to attract and retain additional personnel, we may be unable to achieve profitability.

Our future success is substantially dependent on the efforts of our senior management, particularly Dennis P. Calvert, our president and chief executive officer. The loss of the services of Mr. Calvert or other members of our senior management may significantly delay or prevent the achievement of product development and other business objectives. Because of the scientific nature of our business, we depend substantially on our ability to attract and retain qualified marketing, scientific and technical personnel. There is intense competition among specialized and technologically-oriented companies for qualified personnel in the areas of our activities. If we lose the services of, or do not successfully recruit, key marketing, scientific and technical personnel, then the growth of our business could be substantially impaired. At present, we do not maintain key man insurance for any of our senior management, although management is evaluating the potential of securing this type of insurance in the future as may be available.

Table of Contents

Nondisclosure agreements with employees and others may not adequately prevent disclosure of trade secrets and other proprietary information.

In order to protect our proprietary technology and processes, we rely in part on nondisclosure agreements with our employees, potential licensing partners, potential manufacturing partners, testing facilities, universities, consultants, agents and other organizations to which we disclose our proprietary information. These agreements may not effectively prevent disclosure of confidential information and may not provide an adequate remedy in the event of unauthorized disclosure of confidential information. In addition, others may independently discover trade secrets and proprietary information, and in such cases we could not assert any trade secret rights against such parties. Costly and time-consuming litigation could be necessary to enforce and determine the scope of our proprietary rights, and failure to obtain or maintain trade secret protection could adversely affect our competitive business position. Since we rely on trade secrets and nondisclosure agreements, in addition to patents, to protect some of our intellectual property, there is a risk that third parties may obtain and improperly utilize our proprietary information to our competitive disadvantage. We may not be able to detect unauthorized use or take appropriate and timely steps to enforce our intellectual property rights.

We may become subject to product liability claims.

As a business that manufactures and markets products for use by consumers and institutions, we may become liable for any damage caused by our products, whether used in the manner intended or not. Any such claim of liability, whether meritorious or not, could be time-consuming and/or result in costly litigation. Although we maintain general liability insurance, our insurance may not cover potential claims of the types described above and may not be adequate to indemnify for all liabilities that may be imposed. Any imposition of liability that is not covered by insurance or is in excess of insurance coverage could harm our business and operating results, and you may lose some or all of any investment you have made, or may make, in our company.

Litigation or the actions of regulatory authorities may harm our business or otherwise distract our management.

Substantial, complex or extended litigation could cause us to incur major expenditures and distract our management. For example, lawsuits by employees, former employees, investors, stockholders, partners, customers or others, or actions taken by regulatory authorities, could be very costly and substantially disrupt our business. As a result of our financing activities over time, and by virtue of the number of people that have invested in our company, we face increased risk of lawsuits from investors. Such lawsuits or actions could from time to time be filed against our company and/or our executive officers and directors. Such lawsuits and actions are not uncommon, and we cannot assure you that we will always be able to resolve such disputes or actions on terms favorable to our company.

If we suffer negative publicity concerning the safety or efficacy of our products, our sales may be harmed.

If concerns should arise about the safety or efficacy of any of our products that are marketed, regardless of whether or not such concerns have a basis in generally accepted science or peer-reviewed scientific research, such concerns could adversely affect the market for those products. Similarly, negative publicity could result in an increased number of product liability claims, whether or not those claims are supported by applicable law.

The licensing of our technology or the manufacture, use or sale of products incorporating our technology may infringe on the patent rights of others, and we may be forced to litigate if an intellectual property dispute arises.

If we infringe or are alleged to have infringed another party’s patent rights, we may be required to seek a license, defend an infringement action or challenge the validity of the patents in court. Patent litigation is costly and time consuming. We may not have sufficient resources to bring these actions to a successful conclusion. In addition, if we do not obtain a license, do not successfully defend an infringement action or are unable to have infringed patents declared invalid, we may:

●

incur substantial monetary damages;

●

encounter significant delays in marketing our current and proposed product candidates;

●

be unable to conduct or participate in the manufacture, use or sale of product candidates or methods of treatment requiring licenses;

●

lose patent protection for our inventions and products; or

●

find our patents are unenforceable, invalid or have a reduced scope of protection

Table of Contents

Parties making such claims may be able to obtain injunctive relief that could effectively block our company’s ability to further develop or commercialize our current and proposed product candidates in the United States and abroad and could result in the award of substantial damages. Defense of any lawsuit or failure to obtain any such license could substantially harm our company. Litigation, regardless of outcome, could result in substantial cost to, and a diversion of efforts by, our company.

Our patents are expensive to maintain, our patent applications are expensive to prosecute, and thus we are unable to file for patent protection in many countries.

Our ability to compete effectively will depend in part on our ability to develop and maintain proprietary aspects of our technology and either to operate without infringing the proprietary rights of others or to obtain rights to technology owned by third parties. Pending patent applications relating to our technology may not result in the issuance of any patents or any issued patents that will offer protection against competitors with similar technology. We must employ patent attorneys to prosecute our patent applications both in the United States and internationally. International patent protection requires the retention of patent counsel and the payment of patent application fees in each foreign country in which we desire patent protection, on or before filing deadlines set forth by the International Patent Cooperation Treaty (“PCT”). We therefore choose to file patent applications only in foreign countries where we believe the commercial opportunities require it, considering our available financial resources and the needs for our technology. This has resulted, and will continue to result, in the irrevocable loss of patent rights in all but a few foreign jurisdictions.

Patents we receive may be challenged, invalidated or circumvented in the future, or the rights created by those patents may not provide a competitive advantage. We also rely on trade secrets, technical know-how and continuing invention to develop and maintain our competitive position. Others may independently develop substantially equivalent proprietary information and techniques or otherwise gain access to our trade secrets.

We are subject to risks related to future business outside of the United States.

Over time, we may develop business relationships outside of North America, and as those efforts are pursued, we will face risks related to those relationships such as:

●

foreign currency fluctuations;

●

unstable political, economic, financial and market conditions;

●

import and export license requirements;

●

trade restrictions;

●

increases in tariffs and taxes;

●

high levels of inflation;

●

restrictions on repatriating foreign profits back to the United States;

●

greater difficulty collecting accounts receivable and longer payment cycles;

●

less favorable intellectual property laws, and the lack of intellectual property legal protection;

●

regulatory requirements;

●

unfamiliarity with foreign laws and regulations; and

●

changes in labor conditions and difficulties in staffing and managing international operations.

The volatility of certain raw material costs may adversely affect operations and competitive price advantages for products that incorporate our technology.

Most of the chemicals and other key materials that we use in our business, such as minerals, fiber materials and packaging materials, are neither generally scarce nor price sensitive, but prices for such chemicals and materials can be cyclical. Super Absorbent Polymer (SAP) beads, which are a petrochemical derivative, have been subject to periodic scarcity and price volatility from time to time during recent years, although prices are relatively stable at present. Should the volume of our sales increase dramatically, we may have difficulty obtaining SAP beads or other raw materials at a favorable price. Supply and demand factors, which are beyond our control, generally affect the price of our raw materials. We try to minimize the effect of price increases through production efficiency and the use of alternative suppliers, but these efforts are limited by the size of our operations. If we are unable to minimize the effects of increased raw material costs, our business, financial condition, results of operations and cash flows may be materially adversely affected.

Table of Contents

Certain of our products sales historically have been highly impacted by fluctuations in seasons and weather.

Industrial odor control products have proven highly effective in controlling volatile organic compounds that are released as vapors produced by decomposing waste material. Such vapors are produced with the highest degree of intensity in temperatures between 40 degrees Fahrenheit (5 degrees Celsius) and 140 degrees Fahrenheit (60 degrees Celsius). When weather patterns are cold or in times of precipitation, our clients are less prone to use our odor control products, presumably because such vapors are less noticeable or, in the case of precipitation, can be washed away or altered. This leads to unpredictability in use and sales patterns for, especially, our CupriDyne Clean product line which accounts for over one-half our total sales.

The cost of maintaining our public company reporting obligations is high.

We are obligated to maintain our periodic public filings and public reporting requirements, on a timely basis, under the rules and regulations of the SEC. In order to meet these obligations, we will need to continue to raise capital. If adequate funds are not available, we will be unable to comply with those requirements and could cease to be qualified to have our stock traded in the public market. As a public company, we incur significant legal, accounting and other expenses. In addition, the Sarbanes-Oxley Act of 2002, as well as related rules adopted by the SEC, has imposed substantial requirements on public companies, including certain corporate governance practices and requirements relating to internal control over financial reporting under Section 404 of the Sarbanes-Oxley Act.

Risks Relating to our Common Stock

The sale or issuance of our common stock to Lincoln Park may cause dilution, and the sale of the shares of common stock acquired by Lincoln Park, or the perception that such sales may occur, could cause the price of our common stock to fall.

On August 25, 2017, we entered into the LPC Agreement with Lincoln Park, pursuant to which Lincoln Park has committed to purchase up to $10,000,000 of our common stock, noted above in our Risks Related to our Business. We generally have the right to control the timing and amount of any sales of our shares to Lincoln Park. Sales of our common stock, if any, to Lincoln Park will depend on market conditions and other factors to be determined by us. We may ultimately decide to sell to Lincoln Park all, some or none of the shares of our common stock that may be available for us to sell pursuant to the LPC Agreement. If and when we do sell shares to Lincoln Park, after Lincoln Park has acquired the shares, Lincoln Park may resell all, some or none of those shares at any time or from time to time in its discretion. Therefore, sales to Lincoln Park by us could result in substantial dilution to the interests of other holders of our common stock, as well as sales of our stock by Lincoln Park into the open market causing reductions in the price of our common stock. Additionally, the sale of a substantial number of shares of our common stock to Lincoln Park, or the anticipation of such sales, could make it more difficult for us to sell equity or equity-related securities in the future at a time and at a price that we might otherwise desire to effect sales.

Our common stock is thinly traded and largely illiquid.

Our stock is currently quoted on the OTC Markets (OTCQB). Being quoted on the OTCQB has made it more difficult to buy or sell our stock and from time to time has led to a significant decline in the frequency of trades and trading volume. Continued trading on the OTCQB will also likely adversely affect our ability to obtain financing in the future due to the decreased liquidity of our shares and other restrictions that certain investors have for investing in OTCQB traded securities. While we intend to seek listing on the Nasdaq Stock Market (“Nasdaq”) or another national stock exchange when our company is eligible, there can be no assurance when or if our common stock will be listed on Nasdaq or another national stock exchange.

The market price of our stock is subject to volatility.

●

Because our stock is thinly traded, its price can change dramatically over short periods, even in a single day. An investment in our stock is subject to such volatility and, consequently, is subject to significant risk. The market price of our common stock could fluctuate widely in response to many factors, including:

●

developments with respect to patents or proprietary rights;

●

announcements of technological innovations by us or our competitors;

●

announcements of new products or new contracts by us or our competitors;

●

actual or anticipated variations in our operating results due to the level of development expenses and other factors;

●

changes in financial estimates by securities analysts and whether any future earnings of ours meet or exceed such estimates;

●

conditions and trends in our industry;

Table of Contents

●

new accounting standards;

●

general economic, political and market conditions and other factors; and

●

the occurrence of any of the risks described in this Annual Report.

You may have difficulty selling our shares because they are deemed “penny stocks”.

Because our common stock is not quoted on the Nasdaq National Market or Nasdaq Capital Market or listed on a national securities exchange, if the trading price of our common stock remains below $5.00 per share, which we expect for the foreseeable future, trading in our common stock will be subject to the requirements of certain rules promulgated under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), which require additional disclosure by broker-dealers in connection with any trades involving a stock defined as a penny stock (generally, any non-Nasdaq equity security that has a market price of less than $5.00 per share, subject to certain exceptions). Such rules require the delivery, before any penny stock transaction, of a disclosure schedule explaining the penny stock market and the risks associated therewith and impose various sales practice requirements on broker-dealers who sell penny stocks to persons other than established customers and accredited investors (generally defined as an investor with a net worth in excess of $1,000,000 or annual income exceeding $200,000 individually or $300,000 together with a spouse). For these types of transactions, the broker-dealer must make a special suitability determination for the purchaser and have received the purchaser’s written consent to the transaction before the sale. The broker-dealer also must disclose the commissions payable to the broker-dealer and current bid and offer quotations for the penny stock and, if the broker-dealer is the sole market-maker, the broker-dealer must disclose this fact and the broker-dealer’s presumed control over the market. Such information must be provided to the customer orally or in writing before or with the written confirmation of trade sent to the customer. Monthly statements must be sent disclosing recent price information for the penny stock held in the account and information on the limited market in penny stocks. The additional burdens imposed on broker-dealers by such requirements could discourage broker-dealers from effecting transactions in our common stock, which could severely limit the market liquidity of our common stock and the ability of holders of our common stock to sell their shares.

Because our shares are deemed “penny stocks,” new rules make it more difficult to remove restrictive legends.

Rules put in place by the Financial Industry Regulatory Authority (FINRA) require broker-dealers to perform due diligence before depositing unrestricted common shares of penny stocks, and as such, some broker-dealers, including many national firms (such as eTrade and Charles Schwab), are refusing to deposit previously restricted common shares of penny stocks. As such, it may be more difficult for purchases of shares in our private securities offerings to deposit the shares with broker-dealers and sell those shares on the open market.

Because we will not pay dividends in the foreseeable future, stockholders will only benefit from owning common stock if it appreciates.

We have never declared or paid a cash dividend to stockholders. We intend to retain any earnings that may be generated in the future to finance operations. Accordingly, any potential investor who anticipates the need for current dividends from his investment should not purchase our common stock.

The “as adjusted” column assumes Black Mountain and Gemini both purchase all shares pursuant to their warrants for an aggregate exercise price of $820,000, and that all shares registered hereunder are issued.

DILUTION

The net tangible book value of our company as of December 31, 2018 was negative $1,123,000 or approximately $(0.008) per share of common stock. Net tangible book value per share is determined by dividing the net tangible book value of our company (total tangible assets less total liabilities) by the number of outstanding shares of our common stock.

Assuming all warrants issued to Black Mountain and Gemini are exercised and the exercise price is received by the Company, and the Vista Note is converted to our common stock, our adjusted net tangible book value as of December 31, 2018 would have been negative $303,000 or approximately $(0.002) per share. This represents an immediate increase in net tangible book value of approximately $0.006 per share to existing stockholders.

Securities Authorized for Issuance Under Equity Compensation Plans

On March 7, 2018, our board of directors adopted BioLargo, Inc. 2018 Equity Incentive Plan (“2018 Equity Plan”) as a means of providing our directors, key employees, and consultants additional incentive to provide services. This plan was approved by our stockholders at our annual meeting on May 23, 2018. The Compensation Committee administers this plan, except for awards made to non-employee directors. The plan allows for the grant of stock options, restricted stock awards, stock bonus awards, stock appreciation rights, restricted stock units and performance awards in any combination, separately or in tandem. Subject to the terms of the 2018 Equity Plan, the Compensation Committee will determine the terms and conditions of awards, including the times when awards vest or become payable and the effect of certain events such as termination of employment. Under the 2018 Equity Plan, 40,000,000 shares of our common stock are reserved for issuance under awards. Each January 1, through January 1, 2028, the number of shares available for grant and issuance will be increased by the lesser of 2,000,000 and such number of shares set by the Board. As of December 31, 2018, we had issued options under the plan to purchase 1,318,517 shares.

On August 7, 2007, our board of directors adopted the BioLargo, Inc. 2007 Equity Incentive Plan (“2007 Equity Plan”) as a means of providing our directors, key employees, and consultants additional incentive to provide services. This plan expired on September 6, 2017. The Compensation Committee administers this plan. The plan allowed for grants of common shares or options to purchase common shares. As plan administrator, the Compensation Committee has sole discretion to set the price of the options. The Compensation Committee may at any time amend the plan.

Under the 2007 Equity Plan, as amended in 2011, 12,000,000 shares of our common stock are reserved for issuance under awards. Only shares actually issued under the 2007 Equity Plan will reduce the share reserve. If we acquire another entity through a merger or similar transaction and issue replacement awards under the 2007 Equity Plan to employees, officers and directors of the acquired entity, those awards, to the extent permitted under applicable laws and securities exchange rules, will not reduce the number of shares reserved for the 2007 Equity Plan.

The 2007 Equity Plan imposes additional maximum limitations, which limitations will be adjusted to take into account stock splits, reverse stock splits and other similar occurrences. The maximum number of shares that may be issued in connection with incentive stock options granted to any one person in any calendar year intended to qualify under Internal Revenue Code Section 422 is 160,000 shares. The maximum number of shares that may be subject to stock options or stock appreciation rights granted to any one person in any calendar year is 200,000 shares, except that this limit is 400,000 shares if the grant is made in the year of the recipient’s initial employment. The maximum number of shares that may be subject to restricted stock or restricted stock units granted to any one person in any calendar year is 200,000 shares. The maximum number shares that may be subject to awards granted to any one Participant in any calendar year of (i) performance shares, and/or performance units (the value of which is based on the fair market value of a share), is 200,000 shares; and (ii) of performance units (the value of which is not based on the fair market value of a share) that could result in a payment of more than $500,000.

In addition to the 2007 Equity Plan, our board of directors has approved a plan for employees, consultants and vendors by which outstanding amounts owed to them by our company may be converted to common stock or options to purchase common stock. The conversion and exercise price is based on the closing price of our common stock on the date of agreement. If an option is issued, the number of shares purchasable by the option is calculated by dividing the amount owed by the exercise price, times one and one-half.

DESCRIPTION OF BUSINESS

BioLargo, Inc. is a corporation organized under the laws of the state of Delaware. Since January 23, 2008, our common stock has been quoted on the OTC Bulletin Board (now called the OTCQB – the OTC Markets “Venture Marketplace”) under the trading symbol “BLGO”.

As used in this report, “we” and “Company” refers to (i) BioLargo, Inc., a Delaware corporation; (ii) its wholly-owned subsidiaries BioLargo Life Technologies, Inc., a California corporation, Odor-No-More, Inc., a California corporation, BioLargo Development Corp., a California corporation, BioLargo Engineering, Science & Technologies, LLC, a Tennessee limited liability company, and Canadian subsidiary BioLargo Water, Inc.; and (iii) Clyra Medical Technologies, Inc. (“Clyra”), a partially owned subsidiary.

The following discussion and analysis should be read in conjunction with our unaudited consolidated financial statements and the related notes to the consolidated financial statements included elsewhere in this report.

Our Business- A Sustainable Products, Technology and Solutions Provider

BioLargo, Inc. is an innovative technology developer and environmental engineering company driven by a mission to “ make life better ” by delivering robust, sustainable solutions for a broad range of industries and applications, with a focus on clean water, clean air, and advanced wound care. We develop and commercialize disruptive technologies by providing the capital, support, and expertise to expedite them from “cradle” to “maturity”. Our business strategy is straightforward: we invent or acquire technologies that we believe have the potential to be disruptive in large commercial markets; we incubate and develop these technologies to advance them and promote their commercial success as we leverage our considerable scientific, engineering, and entrepreneurial talent; we then monetize these technical assets through a variety of business structures that may include licensure, joint venture, sale, spin off, or by deploying direct to market strategies. We seek to unlock the value of our portfolio of underlying technologies to both advance our purposeful mission while we create value for our stockholders.

Our first significant commercial success is currently unfolding in our subsidiary, Odor-No-More, Inc., which is focused on odor and volatile organic compound (“VOC”) control products sold under the brands CupriDyne Clean and Nature’s Best Science. We are gearing up for rapid growth as our products are experiencing more widespread market adoption in the waste handling industry through national purchasing agreements with four of the largest industry members. To this end, we have recently begun to offer a menu of services to our clients including engineering design, construction, and installation of misting systems and related equipment used to deliver our liquid chemistry products, as well as ongoing maintenance services for installed systems. We have also begun expanding with early adopters into new vertical segments such as wastewater treatment, the cannabis industry and various industrial facilities like steel manufacturing and livestock processing operations. We recently executed a five-year white-label distribution agreement with Cannabusters, Inc. a company organized and owned by Mabre Corporation to feature our odor and VOC control technology to the cannabis industry in combination with their air handling and air quality systems. We believe this to be an important opportunity for BioLargo’s odor and VOC control products, as the cannabis and hemp industries are predicted to grow significantly in the US in the coming years and are known to contend with significant odor and VOC challenges (read more under Emerging High-Growth Opportunity in Cannabis / Hemp Industry ).

Our second commercial operation, BioLargo Engineering, Science & Technologies, LLC (“BLEST”), provides professional engineering and consulting services to third party clients on a fee-for-service basis, and also serves as our in-house engineering team to advance our proprietary technologies and complement service offerings of our other business segments.

In addition to our two operating subsidiaries, we have technologies and products in the development pipeline progressing towards commercialization, including our water treatment system for decontamination and disinfection (our “Advanced Oxidation System”, or “AOS” – see Pilot Projects discussion below), and our medical products focused on healing chronic wounds, including our recently acquired stem cell therapy called the SkinDisc ^TM , which is focused on regenerative tissue management and is licensed to our subsidiary Clyra Medical Technologies, Inc. (“Clyra Medical”).

We believe our current success with our industrial odor and VOC control products serves to validate our overall business strategy which is focused on technology-based products and services capable of disrupting the status quo in their applicable industry market segment. We believe that the future of our medical and clean water technologies has similar and also very large market opportunities ahead as they are introduced commercially.

Odor-No-More Industrial Odor and VOC Solutions

Our CupriDyne Clean industrial products reduce and eliminate tough odors and VOC’s in various industrial settings, delivered through misting systems, sprayers, water trucks and similar water delivery systems. We believe the product is the number one performing odor-control product in the market, and offers substantial savings to our customers compared with competing products.

Waste Handling

Our customer base for our odor and VOC business is expanding. We are now selling product to four of the largest solid waste handling companies in the country, and also have secured multiple flagship clients in the wastewater treatment industry, which we expect to become a priority market. We are also expanding with early adopters into new industrial markets, including steel manufacturing, paper production, construction, building and facilities management, livestock production, the cannabis industry. Opportunities for our products are available internationally. To that end, we participated in the China InnoStars Semi Finals competition in China in early November, gaining exposure for both our company and our products to stakeholders in China’s air quality and odor control market as well as potential strategic investors. We have in the past and plan to continue marketing these products through industry associations like the “Technology Approval Group” program offered by Isle Utilities that serves the wastewater treatment industry. We also have a number of potential partners actively engaged in commercial trials around the globe and we are actively in discussion with a number of groups to leverage our commercial focus through distribution partnerships.

Many of our customers have adopted CupriDyne Clean as a replacement for a non-performing competitive products, some of which have been in use by customers for as many as 30 years. Upon using CupriDyne Clean, the majority of customers have expressed a very high degree of satisfaction with its performance compared to prior solutions. Because of this, we are realizing systematic adoption by our very large corporate customers and expect to serve these customers for years to come. Our experience has helped refine our value proposition and assemble a comprehensive menu of products and services. Our success in this market has validated the market opportunity for our products and services and encourages us to continue investing in infrastructure and sales and marketing to increase revenues. We estimate there are approximately 2,000 active landfills ² , 8,000 transfer stations ³ , and 15,000 waste water treatment agencies

The total addressable market for the waste handling and wastewater treatment industries is greater than $1.3 billion. While we are still assessing the size of the cannabis, agriculture and steel manufacturing industries, we believe they could readily double the market opportunities for our product CupriDyne Clean.

Turn-key Full-service Solutions

At the request of our clients, we have begun offering a menu of services to landfills, transfer stations, and wastewater treatment facilities. These services include ongoing maintenance and on-site support services to assist our clients in the design and continued use of the various systems that deliver our liquid products in the field (such as misting systems). We have recently expanded these serves to engineering design, construction and installation. Our engineering team at BLEST has been instrumental in supporting these operations. During late 2018 we were awarded and completed more than 15 projects and we currently have more than 10 “design build” bids out to clients for CupriDyne Clean delivery systems.

Regional Adoption

Sales of our CupriDyne Clean products and related services were initially made at the local level, on a per-location/facility basis. We would demonstrate our product to the manager of operations at a transfer station or landfill, and he or she ultimately would decide whether to use our products. If owned by a national company, in some instances before the operations manager could buy our products, we were required to obtain official “vendor” status with the company and sign a “national purchasing agreement” (“NPA”). Doing so required a tremendous amount of effort and time. These agreements typically include the addition of our line of products which will be offered through an online purchasing portal to the members around the nation. The process of integrating the data is often delayed by months from the start date of our agreements given their very technical nature. As an example, we just completed work to finish this portion of the startup process with our fourth national agreement account. These processes establish an easy and familiar selling and purchasing process for the ongoing and long-term relationships we seek to develop. We now have NPAs with four of the largest solid waste handling companies in the United States. Some of these accounts are now introducing us to regional managers around the country who have the ability to direct the facilities in their region to use our product. Because of our continued success with our existing clients, our national accounts are expanding their support for, and expanding resources to encourage increased awareness and broad adoption of our products and services. It is also important to note that we are often replacing companies that have served these customers for 20 to 30 years giving support for our claim of ‘disruption’ to an industry.

We believe that “regional adoption” is a scalable approach for the larger solid waste handling companies that, with sufficient resources, we can implement nationwide. Our current national accounts represent the opportunity to serve more than 3,000 local operations around North America. Because of our success serving the transfer stations, material transfer facilities, and landfills, these very large companies are also evaluating the use of CupriDyne Clean in various transportation segments as well.

New Product Expansion with Existing Customers

In line with our mandate as an innovator and full services solution provider, Odor-No-More was recently asked by one of its national customers to expand the use of its CupriDyne based products to include a wash out and odor control product for transportation devices, compactors and containers. While this work is still early, our first trials demonstrate that the new product saves our customers money and labor costs. Although sales for this new product have just begun, we believe the opportunity for this product is significant.

Emerging High-Growth Opportunity in Cannabis / Hemp Industry

Odor-No-More recently entered into a 5-year “white-label” distribution agreement with Cannabusters, Inc., a sister company to Mabre Air Systems, to sell its CupriDyne Clean odor and VOC control products to Cannabis and Hemp grow and production facilities, which represent a target market that management’s research indicates is in sore need of new odor control products and services. Cannabusters has decades of experience with air quality management through their sister company Mabre Air Systems, a leader in air quality control systems in Italy. Cannabusters has committed to a comprehensive marketing program that includes more than 25 trade show events over the next two years to quickly introduce the Cannabusters product to the cannabis and hemp industries. BioLargo's subsidiary Odor-No-More has committed to manufacture and supply its products containing the patented CupriDyne Clean formula to be distributed under the "Cannabusters ^TM " brand.

The cannabis industry is facing increased scrutiny by regulators to better control of hazardous air pollutants called terpenes that are a natural part of production and processing. These gases can also cause malodors that demand attention and can be problematic as these companies seek to maintain good community relations and avoid legal entanglements or lawsuits over nuisance odors. Odor abatement operating procedures are part and parcel to the permitting processes for companies involved in the industry and have typically included traditional carbon filters. With the growth and concentration of cannabis related operators, the industry has come to recognize that the volume of terpenes and air flow in a typical operation are often more than the traditional carbon filter-based systems can manage effectively. Odor complaints persist. We have been able to successfully demonstrate that our products are effective as eliminating these VOC’s and related odors, just as we have done in the waste handling industry. As a result, we have had a number of experts in the cannabis industry tell us that our products could become part of the ‘best practices’ operating procedures for this industry and are working toward that goal.

The global legal cannabis market is expected to grow to $146.4B in 2025 at an astounding 34.6% annual growth rate. Some call cannabis the 21st century’s gold rush. With an estimated 15,000 companies operating in our California alone, we believe the opportunity for our product is significant. A number of recent examples have surfaced with leading companies in this industry that highlight the nuisance odor issue and their inability to adequately manage the volume of terpenes escaping the operations. To that end, we are organizing a series of strategic relationships within the Cannabis industry to capture the opportunity quickly. We are working to finalize agreements with equipment manufacturers, regulatory consultants, key opinion leaders, and marketing partners. Our value proposition is unmatched for odor and VOC control and this is another great example how our platform continues to expand in high value markets.

Wastewater Treatment

We have begun selling products and services to wastewater treatment facilities in our local markets. Our clients are prominent municipal agencies and have indicated a desire to expand the use of our products and services to additional locations in their service areas. As a result of our success in the field, a client featured our product as an example of ‘Best Practices’ for the waste water treatment industry at a national water quality conference hosted by the Water Environment Federation. We anticipate overall longer selling cycles given the technical sophistication of the customers in this market, and believe that channel partnerships with leading companies that already sell and service this highly technical market will be required for our ultimate success. We are encouraged and are evaluating various strategies to maximize our marketing and selling proposition into this mature and well-established market. We are actively engaged in discussions with potential distribution partners and leading engineering firms with well established relationships to the clients in order to service this very large market.

Infrastructure and Capital Needs for Odor-No-More

We recognize the scope of the opportunity for CupriDyne Clean and related services, and understand the task of building the personnel and infrastructure to become a disruptive company in the waste handling industry. In the United States, we currently operate out of two locations – Southern California and Tennessee. As of now, our manufacturing facilities are located in California. However, we expect to expand our manufacturing and staffing in our Tennessee operation as we achieve critical mass in that region. We are also contemplating the opportunity to establish a manufacturing facility in Canada to serve the Canadian odor and VOC control market. In the meantime, as a result of the rapid adoption we are experiencing in our local Southern California market, we want to focus on adding staff and infrastructure to meet the obvious need for our products and services. Since January 1, 2018, we have added five people in both sales and support roles. We believe that we need to invest in qualified sales and support personnel to properly focus our energies on capturing the client opportunities already under contract with our national accounts and expand revenues accordingly.

We believe that a significant number of personnel will be required to fully service the solid waste handling and wastewater treatment industries. We plan to expand as adequate capital to fund these needs becomes available.

Full Service Environmental Engineering

In September 2017 we formed a subsidiary (BioLargo Engineering, Science & Technologies, LLC, or “BLEST”), for the purpose of offering full service environmental engineering to third parties, and to provide engineering support services to our internal teams to accelerate the commercialization of our AOS technologies. Its website is found at www.BioLargoEngineering.com .

BLEST focuses its efforts in three areas:

●

Providing engineering services to third party client;

●

Supporting the AOS development efforts by working with our Canadian subsidiary, BioLargo Water; and

●

Supporting our team at Odor-No-More to provide engineering and design of the CupriDyne Clean delivery systems.

The subsidiary, opened its office in Oak Ridge (a suburb of Knoxville Tennessee), and entered into employment agreements with seven scientists and engineers who collectively have over two hundred years of experience in diverse engineering fields. The team is led by Randall Moore, who served as Manager of Operations for Consulting and Engineering for the Knoxville office of CB&I Environmental & Infrastructure and was formerly a leader at The Shaw Group, Inc., a Fortune 500 global engineering firm. The other team members are also former employees of CB&I and Shaw. The team is highly experienced across multiple industries and they are considered experts in their respective fields, including chemical engineering, wastewater treatment (including design, operations, data gathering and data evaluation), process safety, energy efficiency, air pollution, design and control, technology evaluation, technology integration, air quality management & testing, engineering management, permitting, industrial hygiene, applied research and development, air testing, environmental permitting, HAZOP review, chemical processing, thermal design, computational fluid dynamics, mechanical engineering, mechanical design, NEPDES permitting, RCRA/TSCA compliance and permitting, project management, storm water design & permitting, computer assisted design (CAD), bench chemistry, continuous emission monitoring system operator, data handling and evaluation and decommissioning and decontamination of radiological and chemical contaminated facilities.

Business Development at BLEST

BLEST has had success in several noteworthy areas in the past months. The company is increasing its customer base and executing more and larger projects than in its first year. Additionally, BLEST has made strides toward creating lucrative new opportunities through development of new processes, which BioLargo intend to seek new IP for where possible.

Notably, BLEST recently begun work to develop a new process by which to manage and mitigate Legionella contamination in the water distribution systems of large buildings including hospitals, office buildings, condos, and more. BioLargo recently filed a patent for this new process, which is referenced below in the Intellectual Property section. BLEST intends to leverage this patented process to offer Legionella mitigation services to customers.

Table of Contents

BLEST was recently awarded an SBIR Phase I Competitive Grant by the Environmental Protection Agency in the amount of $100,000 to investigate solutions for the removal of per- and polyfluoroalkyl substances (PFAS) from water. PFAS have been linked to cancer, fertility problems, asthma, and more, and are present in a vast range of manufactured goods including food, common household products (e.g., cleaning products, cookware), and electronics. PFAS also pose widespread and serious water safety problems around the world, with governments and industry actively seeking new technologies and processes to eliminate PFAS from groundwater and drinking water.

During the first quarter of 2018, BLEST secured a new relationship and was retained to serve as “Owner’s Engineer” for a proposed $687 million integrated biofuels production project to be built on the east coast. The proposed facility would convert hundreds of tons per day of municipal solid wastes and plastics into high-grade fuels and paraffin waxes, while diverting hundreds of thousands of tons of waste from landfills per year. Our team’s initial role in this project is to provide the project’s ownership team with consulting engineering support as the project becomes finalized. BLEST is now under contract to be paid for approximately $195,000 of engineering services rendered for the pre-project phase. We expect our role to expand once the client acquires a final piece of real property necessary for the project and additional funding. Assuming it moves ahead, we anticipate that the scope of our services will significantly expand to an important multi-year role in the project’s overall engineering management. We believe this project will require rapid and detailed response and require that we increase of our Oak Ridge staff to fully meet the demands of the project.

BLEST has recently been notified that as a result of its recent audit work on assisting a leading healthcare products company in transitioning to the 2015 revision of the ISO 14001 standard for environmental management systems (EMS) it is being awarded another small project from the client. The new time and materials project involved preparing a detailed GAP analysis, and subsequently updating the client’s EMS procedures to reflect the significant changes to the new EMS standard which places new emphasis on upper management involvement, the life cycle of products and services, emergency preparedness and response, and sustainability. There is also a new focus on evaluating risks and opportunities and integrating this assessment into the EMS program.

BLEST recently began a time and materials contract of work approaching $100,000 to plan and test to demonstrate that emissions from an energetic materials incinerator at a large U.S. military installation on the East coast are meeting EPA regulatory standards. An “energetic materials incinerator” allows the military to safely dispose propellants, explosives, and munitions that have aged beyond their shelf life. This facility must meet numerous emission standards including regulations that limit emissions of chemical compounds called “dioxins” and “furans”, which are tightly regulated chemicals in nearly every developed country. BLEST, having submitted the draft report for the dioxin test, has been awarded a contract for 2019 to prepare a test plan for the 2020 trial burn of the incineration system at the site. This effort combined with a contract to conduct an environmental audit and conduct training of site personnel will exceed $30,000 for calendar 2019. The anticipated contract for the 2020 test, to be awarded January/February of 2020 will exceed $300,000.

BLEST has now performed seven separate projects for HAVCO Wood Products, totaling over $35,000 with two additional projects scheduled for the second quarter of 2019. We anticipate extending the current Professional Services Agreement into an overall environmental services annual contact with specific annual tasks that will convert this repeat client into a perpetual source of revenue.

The formation of BLEST was predicated on the concept that 60% of the revenue would be provided by external clients and the remaining 40% would be provided by internal clients (i.e. BioLargo Water or Odor-No-More). By reaching this goal, BLEST will provide direct positive cash flow to the BioLargo, Inc. while fulfilling its mission to provide professional engineering services to the internal client base. For calendar 2018, the ratio was approximately 40% of revenue provided by external clients and 60% provided by internal sources. The ratio for 2018 was driven by significant need from the internal client base and circumstances related to the first full year of operation for BLEST. BLEST anticipates the original target ratios to be met or exceeded in calendar 2019. This is based on an increasing number of perpetual contracts including Citizens Gas Utility District, HAVCO, Powell Valley Utilities, and APTIM/Picatinny Arsenal. These perpetual contracts, which are renewed annually, will provide a steady base load of outside client revenue that is reasonably predictable and secure.

In addition to continued organic growth in the external client base, BLEST has developed several business development initiatives including water pollution control services and equipment specifically designed for the microbrewery sector. They have developed a bundle of services and technology-based products to offer a total solution for legionella prevention in public buildings. They are evaluating similar approaches for the cannabis industry as well. These markets are expanding in areas across the United States and represent significant opportunities for BLEST.

BLEST management believes the company can expect growth in several additional areas. For one, BLEST is under contract to design, build, and install wastewater treatment equipment and “treatment trains” for clients in collaboration with BioLargo’s water technology subsidiary BioLargo Water. Not only does this represent important synergy between two BioLargo business units, but it offers BLEST the opportunity to become a total water treatment solutions provider for customers in the widely under-served small industrial wastewater treatment sector. Another area of predicted growth is the conduct of environmental engineering and permitting work for large industrial facilities such as fuel conversion plants, an area in which BLEST has experienced an increasing number of contracts in the past quarter.

BioLargo Water and the Advanced Oxidation System - AOS

BioLargo Water is our wholly owned subsidiary located on campus at the University of Alberta, Canada, that has been primarily engaged in the research and development of our Advanced Oxidation System (AOS). The AOS is our patented water treatment device that generates a series of highly oxidative species of iodine and other molecules that, because of its proprietary configuration and inner constituents, allow it to eliminate pathogenic organisms and organic contaminants as water passes through the device and it performs with extreme efficacy while consuming very little electricity. Its key application is extremely efficient decontamination and the disinfection of various waste waters. The AOS recently began its first pre-commercial pilot project, wherein an AOS and treatment train has been installed on-site at Sunworks Farm, a poultry farm in Alberta. This pilot project is discussed in more detail in the Pre-commercial Pilot Projects section below.

The key value proposition of the AOS is its ability to eliminate a wide variety of contaminants with high performance while consuming extremely low levels of input electricity and extremely low levels of chemistry inputs – a trait made possible by the complex set of highly oxidative iodine compounds generated within the AOS reactor. Our proof-of-concept studies and case studies have generated results that project the AOS will be more cost- and energy-efficient than commonly used advanced water treatment technologies such as UV, electro-chlorination, and ozonation. This value proposition sets the AOS technology above other water treatment options, as we believe the AOS may allow safe and reliable water treatment for significantly lower cost compared to its competitors and may even enable advanced water treatment in applications where it otherwise would have been prohibitively costly.

The AOS has the potential to allow reliable and cost-effective water treatment in numerous industries and applications where high-level disinfection or elimination of hard-to-treat organic contaminants is required. We believe the total serviceable market for our AOS is $10.75 billion for the poultry processing, food & beverage, and storm water segments with a target beachhead market for poultry processing in North America at an estimated $240 million.

Our AOS was the result of breakthroughs in both advanced iodine electrochemistry and advances in materials engineering, and its invention led to BioLargo’s co-founding of a multi-year industrial research chair whose goal was to solve the contaminated water issues associated with the Canadian Oil Sands at the University of Alberta Department of Engineering in conjunction with the top five oil companies in Canada, the regional water district, and various environmental agencies of the Canadian government. Based on recovering oil prices and our ongoing work in Canada, we recently reinitiated discussions with a number of stakeholders in the oil sands industry to support the completion of AOS development for oil and gas water treatment and to discuss the initiation of pre-commercial and commercial pilots for our AOS to help treat and remediate oil sands process-affected water (“OSPW”) found in tailings ponds in the Canadian oil sands, an application that currently has no good economically viable solution. We continue to apply for significant grant funding to re-initiate our work to help treat OSPW and other oil and gas wastewaters using the AOS. We believe that this opportunity requires substantial grant support to be viable for our company and, therefore we will continue to focus on energies on other markets until such time as resources are available.

Our AOS is an award-winning invention that is supported by science and engineering financial support and highly competitive grants (66 and counting) from various federal and provincial funding agencies in Canada such as NSERC, NRC- IRAP, and Alberta Innovates and in the United States by the Metropolitan Water District of Southern California and National Water Research Institute.

Our immediate goals for the development and commercialization of the AOS are: 1) to secure direct investment into the BioLargo Water subsidiary to empower its staff to complete its development cycle, 2) complete the ongoing pre-commercial field pilot studies which are necessary to generate the techno-economic data required to secure commercial trials, entice future customers, and commence traversal of necessary regulatory pathways, 3) conduct the first commercial trials with the AOS, and 4) secure first sale of the AOS. It is our belief that once pre-commercial pilots have concluded with the AOS, our ability to entice major water industry players to partner with BioLargo Water to accelerate market adoption of the AOS will be increased dramatically.

Recent AOS Milestones

The most important advances in AOS development in recent months have been 1) recent validation of the AOS as an effective tool to eliminate hard-to-treat “micropollutants” from wastewater; 2) design and engineering advances and changes to the AOS in preparation for piloting and scale-up for industrial flow-rates and conditions; and 3) the planning and design of pre-commercial field pilot projects.

Table of Contents

One recent and important AOS milestone was the demonstration that it eliminated or reduced the toxicity of certain high-concern pharmaceutical byproducts (micropollutants) common in some municipal wastewater (“MWW”) streams. Currently, there are no economically viable solutions to remove these compounds from MWW, and incumbent technologies fall short. We believe that the value proposition for our AOS for use as a tool for the municipal water treatment industry to efficiently remove micropollutants could increase our total serviceable market to 5% or more of the total industry which is recognized at + $700 billion globally or approximately $35 billion.

Several advances and improvements to the AOS have also been made in recent months with the purpose of preparing the technology for pre-commercial piloting, commercial piloting, and subsequent mass production, as well as to prepare it for scale-up to allow industrial flow rates. These advancements have largely been proprietary physical improvements to the AOS, including the transitioning of the AOS to using inner substrates more amenable to mass-production and greater flow rates and pressures. Management believes it will continue to advance the scale-up to higher volume throughputs of water flow and enhances the AOS ability to be more compact and longer lasting in the field. This work is not complete, but management believes it does represent a significant step forward to achieving high throughput quality results. Importantly, we have also designed and begun assembling our own proprietary water treatment train that will be used in pilots for the AOS and that will pave the way for complete wastewater treatment in industrial settings.

Pre-commercial Pilot Projects for AOS

We are now underway on multiple pre-commercial field pilot projects. The first project involves treating poultry wastewater on-site at a poultry producer’s facility in Alberta Canada, with support from the Poultry Growers Association, where the AOS is being assessed for its ability to eliminate bacteria and other contaminants from the wastewater effectively and cost-efficiently and to establish operating costs (OPEX) and capital costs (CAPEX) in a field setting. Importantly, in this pilot, BioLargo Water built and installed a complete “treatment train” with equipment to address all aspects of the client’s water treatment needs, including organic contaminants, suspended solids, and biological organisms. Therefore, this pilot also represents BioLargo’s first assessment as a “total solutions provider”, which could open the door for a wider array of future water treatment market opportunities. Recently, the BioLargo Water team finishing installing the full AOS treatment train on-site at Sunworks Farm, the location for the pilot. Work is now underway to begin treating the facility’s wastewater.

In the second pilot, the AOS will be used on-site at a Californian brewery as a polishing (final) step in an Aquacycl treatment train to eliminate bacteria and enable wastewater discharge in compliance with Californian regulatory standards. Aquacycl is an emerging waste-water treatment technology company based in the San Diego area that was introduced to our company by The Maritime Alliance, a trade organization in San Diego committed to fostering maritime business and technology innovation. We are a member organization, and our president has recently joined its board of directors. This pilot will help establish the efficacy of the AOS in a field setting, the OPEX and CAPEX of the system, and the AOS’ ability to “plug and play” in the context of diverse supporting equipment and logistics.

In addition to the poultry and brewery pilots, we are negotiating to begin a pilot to treat captured storm water for recycling and reuse that will be backed by a Canadian government grant and will include a leading city planning consultant in Southern California, a leading engineering firm dedicated to the water industry, and a prominent city based in Southern California. Storm water capture and reuse is an emerging market backed by the State of California pursuant to Measure W which sets aside an estimated $300 million a year from a tax to be used for public agencies to invest in related storm water capture and treatment infrastructure. Also, we were recently invited to participate in a pre-commercial pilot treating municipal wastewater in order to remove micropollutants which is organized by one of the leading engineering firms in the water industry in conjunction with prominent water treatment agency in the Pacific Northwest. Finally, we and a Chinese partner were awarded a grant co-funded by the governments of Canada and China to install an AOS pilot unit on-site at a petrochemical plant in Tianjin City, China, where the AOS would be used to eliminate hard-to-treat organic contaminants to new standards set by the Chinese government. However, we have not yet been able to verify the funding to be provided by the Chinese government to our collaborating partner, and thus are not yet fully committed to this project as it may require capital contributions that we are unwilling to commit to provide without additional funding.

All of these pilot projects represent an important step for our AOS technology, as well as for our company. We are confident in our disruptive water treatment technology and have proven its treatment capabilities in the lab ad nauseum. However, pilot projects for the AOS, as with any technology, are crucial to prove its reliability to industry stakeholders as well the capital cost and operating costs of our technology at-scale. These data will be critical to pave the way for future market adoption. As a reminder, we have many other pilots in evaluation to support this same cause.

We believe that our current designs for the AOS are cost-effective, commercially viable and should be ready for their first commercial launch in late 2019 or early 2020. We secured a patent on the AOS in 2018, and another in March 2019. We intend to continue refining and improving the AOS continually to accomplish a series of goals: expanded patent coverage, extended useful life, lower capital costs, lower energy costs, optimized performance, precise configurations for specific industry challenges, portability, and identifying its performance limits. Our current and most pressing goal for the AOS, as evidenced by the pilot projects described above, is to demonstrate its efficacy in field settings, which is a crucial and necessary step for the commercialization of any water treatment system.

Advanced Wound Care - Clyra Medical

We initially formed Clyra Medical to commercialize our technology in the medical products industry, which we believe can be disruptive to many competing product lines. Our initial product designs focus in the “advanced wound care” field, which includes traumatic injury, diabetic ulcers, and chronic hard-to-heal wounds. We also have designs for products focused on preventing or controlling infections. In late 2018, we also acquired our second technology, a stem cell therapy technology, SkinDisc, that is both complementary to our antimicrobial product designs and it also presents a high value proposition to offer stand-alone products to the advanced wound care industry to assist in regenerating tissue. With the addition of highly skilled team members with extensive experience and proven track record of success in the medical industry and, the addition of the SkinDisc, we have expanded our plans to focus and build out a complete line of products to deliver state of the art solutions to assist in healing wounds. Therefore, we are also presently evaluating a number of additional licensing opportunities to add complementary technologies and products to our medical products portfolio with the goal of offering a complete menu of proprietary and patent protected products to better serve the advanced wound care patient population with state-of-the-art medical products. We are presently seeking pre-market clearance for our first advanced wound care product (application in process), from the U.S. Food & Drug Administration (“FDA”) under Section 510(k) of the Food, Drug, and Cosmetic Act.

We believe the total addressable market for Clyra Medical’s existing product designs in the advanced wound care market, dental, orthopedics and regenerative tissue markets will exceed $2.5 billion by 2022.

Our first and original advanced wound care product combines the broad-spectrum antimicrobial capabilities of iodine in a platform complex that promotes and facilitates wound healing. Our products are highly differentiated from existing antimicrobials in multiple ways - by the gentle nature in which they perform, extremely low dosing of active ingredients, reduced product costs, extended antimicrobial activity, and biofilm efficacy. In addition, iodine has no known acquired microbial resistance, unlike many competing products. We believe the future markets for some of our product designs may also include infection control and wound therapy in orthopedics, dental and veterinary markets. We also intend to pursue and study the use of our technology as a complimentary and synergistic platform for use with regenerative tissue therapy.

We have three patent applications pending for medical products, and are preparing additional applications. While these patent applications are pending, we intend to continue expanding patent coverage as we refine and expand our medical products.

We are in the process of obtaining regulatory approval (pre-market clearance) from the FDA for our first advanced wound care product. These efforts are ongoing as of the date of this report. Although the process has taken considerable time and money, and we have faced a number of delays as a result of the FDA’s requirements of us, we remain highly encouraged by our current interactions with the FDA staff and our current position. The process has confirmed that our product design falls in the scope of the 510(k) process and the pathway to clearance has now been better defined by senior staff at FDA. Having had a second in-person meeting with the FDA just prior to filing this report, in order to obtain further clarifications on the data needed, we are preparing to commence a 30-day animal study to confirm that the Clyra product has no adverse effects on wound healing. Our preliminary study (using the same animal and testing protocol required by FDA) confirmed no adverse effects, and thus we are confident that the data generated by this formal study will meet the FDA’s requirements. This animal study is the last material item asked of us by FDA staff, and we believe we can submit this new data and have a response back from the FDA within 90 to 120 days. While we remain confident that we will ultimately receive premarket clearance for this product, and we continue to invest substantial recourses in anticipation of our ultimate success, we are continually reminded by legal counsel that we can make no assurance or prediction as to success of these efforts, or whether additional information will be requested after this animal study, and must wait patiently for the process with the FDA to conclude. Notwithstanding these disclosures, having spent a significant amount of time and money, including two trips to Washington D.C., we are confident we will see a successful conclusion.

We believe this product’s future role in the advanced wound care industry will be disruptive to many incumbent competing products like silver, hypochlorous acid and even other iodine-based products and therefore our extraordinary investment of time and money will have significant opportunity to generate a considerable return on investment as the products find their way through the FDA process for clearance and then to market adoption. Simply stated, we believe it is worth it and that we will succeed.

Our second technology and its related products center around the SkinDisc technology which we acquired in late 2018 from Scion Solutions, LLC (“Scion”). Scion is led by Spencer Brown, a medical device industry veteran with more than 35 years’ experience in sales, account management, and distribution in the medical device industry. The SkinDisc product was developed by Dr. Brock Liden, a renowned medical podiatrist and expert in wound care and diabetic limb salvage. The SkinDisc is a therapy product that uses a patient’s own bone marrow and plasma in a unique mixture to generate a cell-rich bio gel for use with chronic wounds. It has been tested in over 250 patient cases with no adverse effects, and has successfully aided in the salvage of limbs that otherwise would have been amputated. The regenerative tissue therapy technique has been shown to assist in successful wound closure in time frames as short at 4 to 7 weeks with one or two applications and is patent pending.

Clyra Medical also continues to actively work on the development of new products.

Clyra is currently successfully recruiting Key Opinion Leaders from the medial field to join Clyra’s Medical Advisory Board and is actively evaluating a number of technologies and products to add to its product portfolio in anticipation of its near-term plans to launch its commercial sales efforts.

We are committed to see these advanced wound care products go to market and we believe they will make a positive impact for a greater good around the world and generate meaningful financial results for our stockholders.

Scion Solutions Acquisition – SkinDisc ^TM

On September 26, 2018, we and Clyra Medical agreed to a transaction whereby we would acquire the intangible assets of Scion Solutions, LLC (“Scion”), and in particular its stem cell-based technology, the SkinDisc, and the know-how of key team members to support further research as well as the sale and distribution of Clyra Medical’s products based on our BioLargo technologies.

The parties entered into a Stock Purchase Agreement and Plan of Reorganization (“Purchase Agreement”) whereby Clyra Medical acquired (and then sold to BioLargo) the Scion intangible assets, including the SkinDisc. The consideration provided to Scion is subject to an escrow agreement and earn out provisions and includes: (i) 21,000 shares of the Clyra Medical common stock; (ii) 10,000 shares of Clyra Medical common stock redeemable for BioLargo common shares (detailed below); and (iii) a promissory note in the principal amount of $1,250,000 to be paid through new capital investments and revenue, as detailed below. The Clyra Medical common stock was initially held in escrow subject to the new entity raising $1,000,000 “base capital” to fund its business operations, which was raised effective December 17, 2018 (see below). One-half of the common stock was released to scion, and the second half remains subject to the following performance metrics, each vesting one-fifth of the remaining shares of common stock: (a) notification of FDA premarket clearance of certain orthopedics products, or recognition by Clyra Medical of $100,000 gross revenue; (b) the recognition by Clyra Medical of $100,000 in aggregate gross revenue; (c) the granting of all or any part of the patent application for the SkinDisc product, or recognition by Clyra Medical of $500,000 in gross revenue; (d) recognition by Clyra Medical of $1,000,000 in aggregate gross revenue; and (e) recognition by Clyra Medical of $2,000,000 in gross revenue. In addition, Clyra and Scion entered into the $1,250,000 promissory note called for by the Purchase Agreement. The promissory note accrues interest at the rate of 5%. Principal and interest due under the note are to be paid periodically at a rate of 25% of investment proceeds received. If the note is not paid off within 18 months after the date of issuance, it is automatically extended for additional 12-month periods until the note is repaid in full. Payments after the initial 18-month maturity date are required to be made as investment proceeds are received, at a rate of 25% of such proceeds, and 5% of Clyra Medical’s gross revenues.

Immediately following Clyra Medical’s purchase of Scion’s assets, Clyra Medical sold to BioLargo the assets, along with 12,755 Clyra Medical common shares. In exchange, BioLargo issued Clyra Medical 7,142,858 shares of BioLargo common stock. Concurrently, BioLargo licensed back to Clyra Medical the Scion assets. Scion may exchange its 10,000 Clyra Medical common shares for the 7,142,858 shares of BioLargo common stock issued to Clyra Medical, subject to the escrow and earn-out provisions described above. As of December 31, 2018, per the Closing Agreement, one-half of these shares have been earned and thus may be redeemed, and one-half remain subject to the earn-out provisions.

On December 17, 2018, we entered into a closing agreement (“Closing Agreement”) reflecting the satisfaction of the obligation to raise $1,000,000 “base capital” established under the Purchase Agreement. With the satisfaction of the obligation to raise $1,000,000 in base capital, Clyra Medical agreed to release to Scion one-half of the shares of Clyra common stock exchanged for the Scion assets. The remaining Clyra Medical common shares remain subject to the Escrow Agreement dated September 26, 2018, subject to the metrics identified above. We were initially introduced to the SkinDisc product and Scion Solutions through Dr. Liden and Tanya Rhodes’s consulting work with Clyra Medical (both Dr. Liden and Ms. Rhodes have ownership interest in Scion). Prior to the execution of the above-described agreements, BioLargo did not have any material relationship with Scion’s founder Spencer Brown.

Intellectual Property

We have 20 patents issued, including 18 in the United States, and multiple pending. We believe these patents provide a foundation from which to continue building our patent portfolio, and we believe that our technology is sufficiently useful and novel that we have a reasonable basis upon which to rely on our patent protections. We also rely on trade secrets and technical know-how to establish and maintain additional protection of our intellectual property. As our capital resources permit, we expect to expand our patent protection as we continue to refine our inventions as well as make new discoveries. See the detailed discussion below of our patent portfolio.

Table of Contents

We regard our intellectual property as critical to our ultimate success. Our goal is to obtain, maintain and enforce patent protection for our products and technologies in geographic areas of commercial interest and to protect our trade secrets and proprietary information through laws and contractual arrangements.

Our Chief Science Officer, Mr. Kenneth R. Code, has been involved in the research and development of the technology since 1997. He has participated in the Canadian Federal Scientific Research and Experimental Development program, and he was instrumental in the discovery, preparation and filing of the first technology patents. He has worked with manufacturers, distributors and suppliers in a wide variety of industries to gain a full appreciation of the potential applications and the methodologies applicable to our technology for their manufacture and performance. He continues to research methods and applications to continue to expand the potential uses of our technology as well as work to uncover new discoveries that may provide additional commercial applications to help solve real world problems in the field of disinfection.

We incurred approximately $1,700,000 in expense related to our research and development activities in 2018, an increase of approximately $100,000 over the prior year. We have shifted the focused in our Canadian research facility to focus on commercializing our AOS technology and thus expect these expenses to decrease in 2019.

We believe that our suite of intellectual property covers the presently targeted major areas of focus for our licensing strategy. The description of our intellectual property, at present, is as follows:

●

U.S. Patent 10,238,990, issued on March 26, 2019, and 10,051,866, issued on August 21, 2018, which protect our AOS system.

Pending Patent Applications

Most recently, we filed two patent applications in the United States for our advanced wound care formulas. The inventions in these applications form the basis for the work at Clyra Medical and the products for which that subsidiary intends to seek FDA approval. In addition to these applications, we have filed patent applications in multiple foreign countries, including the European Union, pursuant to the PCT, and other provisional applications.

Subject to adequate financing, we intend to continue to expand and enhance our suite of intellectual property through ongoing focus on product development, new intellectual property development and patent applications, and further third-party testing and validations for specific areas of focus for commercial exploitation. We currently anticipate that additional patent applications will be filed during the next 12 months with the USPTO and the PCT, although we are uncertain of the cost of such patent filings, which will depend on the number of such applications prepared and filed. The expense associated with seeking patent rights in multiple foreign countries is expensive and will require substantial ongoing capital resources. However, we cannot give any assurance that adequate capital will be available. Without adequate capital resources, we will be forced to abandon patent applications and irrevocably lose rights to our technologies.

Competition

We believe that our products contain unique characteristics that distinguish them from competing products. In spite of these unique characteristics, our products face competition from products with similar prices and similar claims. We face stiff competition from companies in all of our market segments, and many of our competitors are larger and better-capitalized.

For example, we would compete with the following leading companies in our respective markets:

●

Disinfecting/Sanitizing : Johnson & Johnson, BASF Corporation, Dow Chemical Co., E.I. DuPont De Nemours & Co., Chemical and Mining Company of Chile, Inc., Proctor and Gamble Co., Diversey, Inc., EcoLab, Inc., Steris Corp., Clorox, and Reckitt Benckiser.

●

Water Treatment : GE Water, Trojan UV, Ecolab, Pentair, Xylem and Siemens AG.

●

Medical Markets : Smith & Nephew, 3M, ConvaTec and Derma Sciences.

●

Pet Market : Arm & Hammer and United Pet Group (owner of Nature’s Miracle branded products).

●

Industrial Odor Control : MCM Odor Control and OMI Industries.

Table of Contents

Each of these named companies and many other competitors are significantly more capitalized than we are and have many more years of experience in producing and distributing products.

Additionally, our technology and products incorporating our technology must compete with many other applications and long embedded technologies currently on the market (such as, for example, chlorine for disinfection).

In addition to the competition we face for our existing products, we are aware of other companies engaged in research and development of other novel approaches to applications in some or all the markets identified by us as potential fields of application for our products and technologies. Many of our present and potential competitors have substantially greater financial and other resources and larger research and development staffs than we have. Many of these companies also have extensive experience in testing and applying for regulatory approvals.

Finally, colleges, universities, government agencies, and public and private research organizations conduct research and are becoming more active in seeking patent protection and licensing arrangements to collect royalties for the use of technology that they have developed, some of which may be directly competitive with our applications.

Governmental Regulation

We will have products (each a ‘‘Medical Device”) that will be subject to the Federal Food, Drug, and Cosmetic Act, as amended (including the rules and regulations promulgated thereunder, the “FDCA”), or similar Laws (including Council Directive 93/42/EEC concerning medical devices and its implementing rules and guidance documents) in any foreign jurisdiction (the FDCA and such similar Laws, collectively, the “Regulatory Laws”) that are developed, manufactured, tested, distributed or marketed by our company or its subsidiary Clyra. Each such Medical Device will need to be developed, manufactured, tested, distributed, and marketed in compliance with all applicable requirements under the Regulatory Laws, including those relating to investigational use, premarket clearance or marketing approval to market a medical device, good manufacturing practices, labeling, advertising, record keeping, filing of reports and security, and in compliance with the Advanced Medical Technology Association Code of Ethics on Interactions with Healthcare Professionals.

We believe that no article or part of any Medical Device intended to be manufactured or distributed by our company or any of our subsidiaries will be classified as (i) adulterated within the meaning of Sec. 501 of the FDCA (21 U.S.C. § 351) (or other Regulatory Laws), (ii) misbranded within the meaning of Sec. 502 of the FDCA (21 U.S.C. § 352) (or other Regulatory Laws) or (iii) a product that is in violation of Sec 510 of the FDCA (21 U.S.C. § 360) or Sec. 515 of the FDCA (21 U.S.C. § 360e) (or other Regulatory Laws).

Neither our company nor any of its subsidiaries, nor, to the knowledge of our company, any officer, employee or agent of our company or any of its subsidiaries, has been convicted of any crime or engaged in any conduct for which such Person or entity could be excluded from participating in the federal health care programs under Section 1128 of the Social Security Act of 1935, as amended (the “Social Security Act”), or any similar Law in any foreign jurisdiction.

Neither our company nor any of its subsidiaries has received any written notice that the FDA or any other Governmental Authority has commenced, or threatened to initiate, any action to enjoin research, development, or production of any Medical Device.

Employees

As of the date of this prospectus, we employ 25 persons. We also engage consultants on an as needed basis who provide certain specified services to us.

Results of Operations—Comparison of the years ended December 31, 2017 and 2018

We operate our business in distinct business segments:

●

Odor-No-More, which manufactures and sells our odor and VOC control products and services, including our flagship product, CupriDyne Clean;

●

BLEST, our professional engineering services division supporting our internal business units and serving outside clients on a fee for service basis;

●

BioLargo Water, our Canadian division that has been historically pure research and development, and is now transitioning to focus on commercializing our AOS system;

●

Clyra Medical, our partially owned subsidiary focused on the Advanced Wound Care industry; and

●

Our corporate operations, which support the operating segments with legal, accounting, human resources, and other services.

We invest cash into each of these segments on a regular basis, as none of the segments yet generates enough cash to fund their operations. However, both Odor-No-More and BLEST are trending towards cash-flow positive, and we expect each of those two segments to begin to generate positive cash for BioLargo in 2019.

Annual revenue for the year ended December 31, 2018 was $1,364,000, more than double the revenue of $516,000 in 2017. We generated revenue from two of our operating divisions – Odor-No-More and BLEST. Our business segments obtain cash to support operations in different ways. Odor-No-More and BLEST generate revenues from third parties, and receive funding as needed from their parent corporation, BioLargo. Our Canadian team, BioLargo Water, receives funds from government research grants (reported on our financial statements as “Other income – Grant income”), and receives funding as needed from BioLargo. Clyra Medical, however, relies direct investment from third parties for 100% of its operating costs and is not supported with capital from BioLargo’s corporate budget or fundraising.

Odor-No-More

Our wholly owned subsidiary Odor-No-More generates revenues through sales of our flagship product CupriDyne Clean, by providing design, installation, and maintenance services on the systems that deliver CupriDyne Clean at its clients’ facilities, and through sales of odor absorption products to the U.S. Government. Although Odor-No-More did not generate a net profit in 2018, its revenues continued to increase throughout the year, and in the fourth quarter of 2018 its net loss was only $68,000 (for the year, its net loss was $433,000).

Revenue (Odor-No-More)

Odor-No-More’s revenues more than doubled in 2018, to $1,123,000, comprised of $1,016,000 in product sales, and $107,000 in design, installation and maintenance services (including related parts). Of product sales, approximately 50% was generated from sales of CupriDyne Clean products, and approximately one-third from sales to the U.S. military.

Table of Contents

Sales of our CupriDyne Clean products increased 68% from the prior year, due to the acquisition of more clients and client locations, and the sale and delivery of more products than in years past. Of our CupriDyne Clean sales, approximately two-thirds were made pursuant to “national purchasing agreements” (“NPA”) with the four largest waste handling companies in the United States. We expect our sales to NPA clients to continue to increase in 2019 as we expect to continue to add new service locations for those customers. And, for one such company, we have only recently become fully authorized in their corporate system, opening up potential sales to their more than 1,000 U.S. locations.

Sales to the U.S. military are primarily our Specimen Transport Solidifier pouches, and are made to the U.S. Defense Logistics Agency through our distributor Downeast Logistics. These sales increased by almost three-fold in 2018 as compared with 2017. The vast majority of these sales are made through a bid process in response to a request for bids to which any qualified government vendor can respond, and our increased revenue in 2018 is due to an increased volume of sales from the bidding process. We cannot know in advance the frequency or size of such requests from the US Government, or whether our bids will be successful, and as such we are uncertain as to our future revenues through this system.

Cost of Goods Sold (Odor-No-More)

Odor-No-More’s cost of goods sold includes costs of raw materials, contract manufacturing, and portions of salaries and expenses related to the manufacturing of our products. As a percentage of gross sales, Odor-No-More’s costs of goods was 51% in 2018 versus 64% in 2017. In mid-2018, because of higher volumes, Odor-No-More was able to decrease its costs by purchasing raw materials directly from manufacturers at more favorable prices, resulting in the year-to-year cost of goods decrease.

Selling, General and Administrative Expense (Odor-No-More)

Odor-No-More’s Selling, General and Administrative (“SG&A”) expenses include both cash and non-cash expense related to its operations. Odor-No-More’s SG&A expenses increased to $969,000 in 2018, as compared with $661,000 in 2017, an increase of 47%. These expenses have increased alongside Odor-No-More’s efforts to increase revenues by hiring additional sales and support staff. We expect its SG&A expenses to increase in 2019 as it continues to add sales and support personnel as its number of customers and revenues increase.

Net Loss (Odor-No-More)

Odor-No-More generated $1,123,000 in revenue, a gross margin of $552,000, and had total costs and expenses of $985,000, resulting in a net loss of $433,000. Odor-No-More is trending toward profitability. Its gross margin from product sales has increased significantly since 2017, and its loss from operations is trending downward:

We believe these trends will continue. The loss from operations is trending downward for two reasons. First, Odor-No-More was able to reduce its product costs as a result of its increased volume (purchasing power). Second, increased sales resulted in increased gross margin contributing to the company’s operational costs.

Because the subsidiary had a net loss, we invested cash into it during the year to allow it to fund its operations. However, this need for cash decreased as 2018 progressed, and in the fourth quarter of 2018, it needed only $51,000 cash (as compared with over $400,000 for the year). We expect that Odor-No-More’s sales will continue to increase, and thus its gross margin will continue to increase. By the end of 2019, we expect that Odor-No-More will no longer require a cash subsidy to operate, but will be contributing cash to our corporate operations.

BLEST (engineering division)

Revenue (BLEST)

Our engineering segment (BLEST) generated $241,000 of revenues from third party clients in its first full year of operation, versus only $12,000 in revenue in its first three months of operation in 2017. BLEST’s revenues increased in the latter part of the year, with approximately one-half of its revenues generated during the fourth quarter 2018. Its revenues do not include over $600,000 of work performed on internal BioLargo projects, such as its further engineering and development of the AOS water filtration system. Our engineers are performing a critical role in the AOS pilot projects, some of which are supported by third-party research grants and has been instrumental in developing and supporting a professional engineered design service for misting systems being sold by our Odor-No-More operating unit.

Cost of Goods (Services) Sold (BLEST)

BLEST’s cost of services includes employee labor as well as subcontracted labor costs. In 2018, its cost of services were 71% of its revenues, versus 66% in 2017. We expect the cost of services to remain stable in 2019.

Selling, General and Administrative Expense (BLEST)

BLEST’S SG&A expenses include both cash and non-cash expense related to its operations, although because it primarily delivers services to its clients, most of its labor costs are included in its cost of services (for third party clients), and research and development for its work on BioLargo technologies. Because BLEST began operations in the fourth quarter of 2017, and thus its SG&A expenses of $409,000 in 2018 does not have a comparable period in 2017. We expect these expenses to increase only slightly in 2019, as the staff required to increase service to its clients and revenues will be included in cost of services.

Net Loss (BLEST)

BLEST generated $241,000 in revenue, a gross margin of $69,000, and had total costs and expenses of $991,000, resulting in a net loss of $750,000.

While we are unable to record revenues generated from intracompany services by the engineering group to other operating divisions, it is important to note that the net loss would be eliminated if BLEST were an outside contract for hire services company selling services to our water company or our industrial odor and VOC control operating unit.

Because the subsidiary had a net loss, we invested cash during the year to allow it to maintain operations. BLEST’s need for a cash subsidy to support its operations decreased considerably towards the end of calendar year 2018. We expect this trend to continue, and expect that in 2019 its sales will continue to increase, and thus its gross profit will continue to increase. By the end of 2019, we expect that it will no longer require a cash subsidy to operate, but will be contributing cash to our corporate operations.

Other Income

Our wholly owned Canadian subsidiary has been awarded more than 65 research grants over the years from various Canadian public and private agencies, including the Canadian National Research Institute – Industrial Research Assistance Program (NRC-IRAP), the National Science and Engineering Research Council of Canada (NSERC), and the Metropolitan Water District of Southern California’s Innovative Conservation Program “ICP”. The research grants received are considered reimbursement grants related to costs we incur and therefore are included as Other Income. The amount of grant income remained consistent between 2017 and 2018. We continued to win grants and it is important to note that amounts paid directly to third parties are not included as income in our financial statements.

Our Canadian subsidiary applied for and received a refund on our income taxes pursuant to the “Scientific Research and Experimental Development (SR&ED) Program”, a Canadian federal tax incentive program designed to encourage Canadian businesses to conduct research and development in Canada. For the year ended December 31, 2017 and 2018, we received $71,000 and $73,000.

Although we are continuing to apply for government and industry grants, and indications from the various grant agencies is highly encouraging, we cannot be certain of continuing those successes in the future.

Selling, General and Administrative Expense – company wide

Our SG&A expenses include both cash expenses (for example, salaries to employees) and non-cash expenses (for example, stock option compensation expense). Our SG&A expenses increased by 19% ($834,000) in 2018 to $5,264,000. ⁵ Our non-cash expenses (through the issuance of stock and stock options) increased in 2018 compared with 2017 ($2,242,000 compared to $1,564,000) because our employees, vendors and consultants chose to receive a greater number of stock and stock options in lieu of cash owed. The largest components of our SG&A expenses included (in thousands):

	Year ended December 31, 2017		Year ended December 31, 2018
Salaries and payroll related	$	1,610	$	1,973
Professional fees		651		800
Consulting		810		839
Office expense		627		987
Board of director expense		306		280
Sales and marketing		224		246
Investor relations		201		139

Our salaries and payroll-related and office-related expenses increased in 2018 due to the addition of our engineering subsidiary for the full year of 2018 compared to only three months of 2017. Our professional fees increased in 2018 due to increased needs for legal and accounting as a result of the registration statements filed during 2018, the special stockholder meeting held in September 2018 and other work related to our efforts to list our common stock on a national exchange, and the purchase of the intellectual property of Scion Solutions (see Part I, Item I, “Advanced Wound Care – Clyra Medical,” above). Office expense increased due to the addition our engineering segment in Tennessee. Our investor relations fees decreased in 2018 compared with 2017 due to a reduction in the use of outside investor relation firms during that period. The Company has maintained investor relations support with internal personnel.

Research and Development

In the year ended December 31, 2018, we spent approximately $1,700,000 in the research and development of our technologies and products. This was a slight increase of 5% ($86,000) over 2017. This number does not include over $300,000 in internal billings from our engineering division’s work on the AOS system.

As we transition our Canadian operations from pure research and development towards a focus on commercializing the AOS system, we expect their contribution to our total research and development expenses to decrease in 2019. We expect this to be offset by increased research and development at Clyra Medical, which we expect to be funded entirely from its own resources.

Interest expense

Our interest expense for the year ended December 31, 2018 was $3,494,000, a decrease of $366,000 compared with 2017, and of which $54,000 was paid in cash, and the remainder, $3,440,000, is non-cash expense. Our non-cash interest related expenses were comprised primarily as follows: (i) $2,766,000 as one-time, non-cash debt discounts related to warrants issued in conjunction with debt instruments being amortized over the life of the debt instrument (in 2017, it was $3,058,000), and (ii) $524,000 related to interest paid in stock on debt instruments. While we cannot predict our interest expense in 2019, our outstanding debt as of December 31, 2018 was substantially less than as of December 31, 2019, and thus we expect our interest expense in 2019 to decline.

We record the relative fair value of the warrants and the intrinsic value of the beneficial conversion feature sold with the convertible notes payable which typically results in a full discount on the proceeds from the convertible notes. This discount is being amortized as interest expense over the term of the convertible notes. We expect our interest expense to decrease in 2019 because the total amount we amortize (the line item on our balance sheet “Discount on convertible notes payable and line of credit, net of amortization”) decreased by $1,784,000 in 2018 – from $2,107,000 at December 31, 2017, to $323,000 at December 31, 2018. However, any decrease would be offset if we issue new debt instruments in 2019 that are combined with warrants, or if we issue new warrants as consideration to extend maturity dates on existing debt instruments.

Net Loss

Net loss for the year ended December 31, 2018 was $10,696,000 a loss of $0.09 per share, compared to a net loss for the year ended December 31, 2017 of $9,547,000 a loss of $0.10 per share. Our net loss this year was somewhat offset by an increase in revenue; nevertheless, the net loss increased mainly due to the increase in financing costs, non-cash interest expense to obtain capital, and increased payroll and related office expenses which are primarily associated with the start-up expenses related to our engineering operating unit. The decrease in net loss per share for the year ended December 31, 2018 is primarily attributable to the increase in the number of shares outstanding from 2017 to 2018.

⁽⁵⁾ This includes all of our operational segments (including Odor-No-More and BLEST discussed above).

Table of Contents

The net loss per business segment is as follows (in thousands):

Net loss	Year ended December 31, 2017	Year ended December 31, 2018
Odor-No-More	$(500)	$(433)
BLEST	(90)	(750)
Clyra Medical	(915)	(883)
BioLargo Water	(741)	(571)
Corporate	(7,301)	(7,931)

Consolidated net loss	$(9,547)	$(10,696)

It is important to note that of the corporate net loss of $7,931,000, interest expense was $3,494,000, of which $3,290,000 was a non-cash expense. R & D was $1,700,000 primarily attributed to the accelerated development of the AOS technology. These two items alone account for $5.2 million in losses of the consolidated loss of $10,696,000 in total losses. With expanding sales , we believe that Odor-No-More and BLEST (engineering) can achieve positive cash flow from operations. However, with the continued development costs associated with Clyra Medical (even though it is financed directly through the sale of stock in Clyra), and with the addition of any ongoing development costs associated with BioLargo Water to be incurred through pre-commercial piloting, we expect to continue to incur a net loss for the foreseeable future.

We have made considerable investments in our water and medical technologies as well as supporting the start-up expenses for our engineering team. We believe those investment will pay off as we now are narrowly focused on commercial sales.

Liquidity and Capital Resources

We operate our business in five distinct business segments. Each of these segments obtains cash to fund operations in unique ways. Odor-No-More and BLEST generate cash by selling products and services. Clyra Medical obtains cash from third party investments of sales of its common stock. BioLargo Water generates cash through government research grants and tax credits. Our corporate operations generate cash through private offerings of stock, debt instruments, and warrants. In 2018, cash was generated as follows (in thousands):

	2017 (year)	2018 (Year)
SOURCES OF INCOME AND CASH
Revenue from operations	$516	$1,364
Grant income	140	158
Tax credit income	71	73
Cash investments (to BioLargo)	3,373	2,637
Cash investments (to Clyra)	750	1,005
Total :	$4,850	$5,237

Table of Contents

Only two segments (Odor-No-More and BLEST) generated revenues in the year ended December 31, 2018. As such, we provided a cash subsidy to each business segment to allow it to fund its operations. For our two revenue generating divisions, cash needs have decreased as their revenues have increased. In the fourth quarter of 2018, Odor-No-More’s gross margin and cash receipts from clients were such that it needed only $51,000 extra cash from corporate to meet its operational expenses. BLEST similarly increased its revenues such that it needed little cash from corporate during the fourth quarter to maintain it operations. We expect these trends to continue, and expect that at some point in the calendar year 2019 both Odor-No-More and BLEST will be generating profits and contributing cash to corporate operations.

In the first quarter of 2019, we shifted focus at our Canadian subsidiary (BioLargo Water) from pure research and development to commercializing the AOS system. In doing so, we reduced our research staff and thus reduced its monthly cash needs by $15,000.

Clyra Medical is unique in that it funds its operations through third party investments. We do not intend to subsidize its operations in the future.

We used almost four million dollars cash in our total operations in 2018. At December 31, 2018, we had current assets of just less than one million dollars. Thus, to maintain the same level of operations in 2019, and notwithstanding the increasing revenues at Odor-No-More and BLEST, we expect to continue to need to raise investment capital. In 2018, we conducted private securities offerings and received $3,642,000 net proceeds. Since first acquiring the BioLargo technology in the spring of 2007, we have received investment capital of approximately $22,000,000 which we have invested in development and commercialization efforts. We intend to continue to raise money through private securities offerings for the foreseeable future. Although we engaged an investment banking firm and filed a registration statement to raise $7,500,000 in conjunction with an application for listing our common stock on the Nasdaq Capital Markets, no assurance can be made that we will move forward in the near future with that offering or our listing application. We may reconsider and postpone these efforts as management believes our current market capitalization does not reflect the true value of the Company or recognize the significant business opportunities that lie ahead. Our board intends to evaluate these and other factors, including the anticipated dilution to our stockholders of an offering of the size required to meet the initial and continued listing requirements. No assurance can be made of our success at raising money through private or public offerings, or of our intended listing on a national exchange.

Critical Accounting Policies

Our discussion and analysis of our results of operations and liquidity and capital resources are based on our consolidated financial statements, which have been prepared in accordance with accounting principles generally accepted in the United States. The preparation of these financial statements requires us to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses, and disclosure of contingent assets and liabilities. On an ongoing basis, we evaluate our estimates and judgments, including those related to revenue recognition, valuation of offerings of debt with equity or derivative features which include the valuation of the warrant component, any beneficial conversion feature and potential derivative treatment, and share-based payments. We base our estimates on anticipated results and trends and on various other assumptions that we believe are reasonable under the circumstances, including assumptions as to future events. These estimates form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. By their nature, estimates are subject to an inherent degree of uncertainty. Actual results that differ from our estimates could have a significant adverse effect on our operating results and financial position. We believe that the following significant accounting policies and assumptions may involve a higher degree of judgment and complexity than others.

The methods, estimates and judgments the Company uses in applying these most critical accounting policies have a significant impact on the results of the Company reports in its financial statements.

Revenue Recognition

We adopted ASU 2014-09, “Revenue from Contracts with Customers”, Topic 606, on January 1, 2018. The guidance focuses on the core principle for revenue recognition.

The core principle of the guidance is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. To achieve that core principle, an entity should apply the following steps:

Step 1:

Identify the contract(s) with a customer.

Table of Contents

Step 2:

Identify the performance obligations in the contract.

Step 3:

Determine the transaction price.

Step 4:

Allocate the transaction price to the performance obligations in the contract.

Step 5:

Recognize revenue when (or as) the entity satisfies a performance obligation.

We have revenue from two subsidiaries, Odor-No-More and BLEST. Odor-No-More identifies its contract with the customer through a written purchase order , in which the details of the contract are defined including the transaction price and method of shipment. The only performance obligation is to create and ship the product and each product has separate pricing. Odor-No-More recognizes revenue at a point in time when the order for its goods are shipped if its agreement with the customer is FOB Odor-No-More’s warehouse facility, and when goods are delivered to its customer if its agreement with the customer is FOB destination. Revenue is recognized with a reduction for sales discounts, as appropriate and negotiated in the customer’s purchase order.

BLEST identifies services to be performed in a written contract, which specifies the performance obligations and the rate at which the services will be billed. Each service is separately negotiated and priced. Revenue is recognized as services are performed and completed. BLEST’s contracts typically call for invoicing for time and materials incurred for that contract. To date, there have been no discounts or other financing terms for the contracts.

In the future, we may generate revenues from royalties or license fees from our intellectual property. In the event we do so, we anticipate a licensee would pay a license fee in one or more installments and ongoing royalties based on their sales of products incorporating or using our licensed intellectual property. Upon entering into a licensing agreement, we will determine the appropriate method of recognizing the royalty and license fees.

Warrants

Warrants issued with our convertible and non-convertible debt instruments are accounted for under the fair value and relative fair value method.

The warrant is first analyzed per its terms as to whether it has derivative features or not. If the warrant is determined to be a derivative and not qualify for equity treatment, then it is measured at fair value using the Black Scholes option model, and recorded as a liability on the balance sheet. The warrant is re-measured at its then current fair value at each subsequent reporting date (it is “marked-to-market”).

If the warrant is determined to not have derivative features, it is recorded into equity at its fair value using the Black Scholes option model, however, limited to a relative fair value based upon the percentage of its fair value to the total fair value including the fair value of the convertible note.

Convertible debt instruments are recorded at fair value, limited to a relative fair value based upon the percentage of its fair value to the total fair value including the fair value of the warrant. Further, the convertible debt instrument is examined for any intrinsic beneficial conversion feature (“BCF”) of which the conversion price is less than the closing common stock price on date of issuance. If the relative fair value method is used to value the convertible debt instrument and there is an intrinsic BCF, a further analysis is undertaken of the BCF using an effective conversion price which assumes the conversion price is the relative fair value divided by the number of shares the convertible debt is converted into by its terms. The BCF value is accounted for as equity.

The warrant and BCF relative fair values are also recorded as a discount to the convertible promissory notes. As present, these equity features of the convertible promissory notes have recorded a discount to the convertible notes that is substantially equal to the proceeds received.

Share-based Payments

It is the Company’s policy to expense share-based payments as of the date of grant or over the term of the vesting period in accordance with Auditing Standards Codification Topic 718 “Share-Based Payment.” Application of this pronouncement requires significant judgment regarding the assumptions used in the selected option pricing model, including stock price volatility and employee exercise behavior. Most of these inputs are either highly dependent on the current economic environment at the date of grant or forward-looking expectations projected over the expected term of the award.

Table of Contents

Fair Value Measurement

Generally accepted accounting principles establishes a hierarchy to prioritize the inputs of valuation techniques used to measure fair value. The hierarchy gives the highest ranking to the fair values determined by using unadjusted quoted prices in active markets for identical assets (Level 1) and the lowest ranking to fair values determined using methodologies and models with unobservable inputs (Level 3). Observable inputs are those that market participants would use in pricing the assets based on market data obtained from sources independent of the Company. Unobservable inputs reflect the Company’s assumptions about inputs market participants would use in pricing the asset or liability developed based on the best information available in the circumstances. The Company has determined the appropriate level of the hierarchy and applied it to its financial assets and liabilities.

Management believes the carrying amounts of the Company’s financial instruments as of December 31, 2017 and 2018 approximate their respective fair values because of the short-term nature of these instruments. Such instruments consist of cash, accounts receivable, prepaid assets, accounts payable, convertible notes, and other assets and liabilities.

Committees of our Board of Directors

Our board of directors has established an Audit Committee, a Compensation Committee, and a Nominating and Corporate Governance Committee.

The Audit Committee meets with management and our independent registered public accounting firm to review the adequacy of internal controls and other financial reporting matters. Dennis E. Marshall served as Chairman of the Audit Committee during 2015 and continues to serve in that capacity. John S. Runyan also serves on the Audit Committee. Our board of directors has determined that Mr. Marshall qualifies as an “audit committee financial expert” as defined in Item 401(h) of Regulation S-K of the Securities Exchange Act of 1934, as amended. The Audit Committee met five times in 2016, and four times in each of 2017 and 2018.

The Compensation Committee reviews the compensation for all our officers and directors and affiliates. The Committee also administers our equity incentive option plan. Mr. Marshall served as Chairman of the Compensation Committee until October 2016, at which time Mr. John S. Runyan was appointed chairman. He continues to serve in that capacity and Mr. Marshall remains on the committee. The Compensation Committee met three times in 2016, once in 2017 (with three other actions via unanimous consent), and once in 2018 (with three other actions via unanimous consent).

Our board of directors did not modify any action or recommendation made by the Compensation Committee with respect to executive compensation for the 2016, 2017 or 2018 fiscal years. It is the opinion of the Compensation Committee that the executive compensation policies and plans provide the necessary total remuneration program to properly align their performance and the interests of our stockholders using competitive and equitable executive compensation in a balanced and reasonable manner, for both the short and long term.

The Nominating and Corporate Governance Committee was established in November 2018. Its responsibilities include to identify and screen individuals qualified to become members of the Board, to make recommendations to the Board regarding to the Board regarding the selection and approval of the nominees for director to be submitted to a stockholder vote at the annual meeting of stockholders, subject to approval by the Board, to development corporate governance guidelines and oversee corporate governance practices, to develop a process for an annual evaluation of the Board and its committees, to review all director compensation and benefits, to review, approve and oversee and related party transaction, to develop and recommend director independent standards, and to develop and recommend a company code of conduct, to investigate any alleged breach and enforce the provisions of the code. This committee has not yet held any meetings or taken any formal action.

Our board of directors follows a written code of ethics that applies to its principal executive officers, principal financial officer, principal accounting officer or controller, or persons performing similar functions.

Leadership Structure of our Board of Directors

Mr. Calvert serves as both principal executive officer and Chairman of the Board. Our company does not have a lead independent director. Messrs. Marshall, Roberts, Strommen and Runyan serve as independent directors who provide active and effective oversight of our strategic decisions. As of the date of this prospectus, our company has determined that the leadership structure of our board of directors has permitted our board of directors to fulfill its duties effectively and efficiently and is appropriate given the size and scope of our company and its financial condition.

Our Board of Directors’ Role in Risk Oversight

As a smaller company, our executive management team, consisting of Messrs. Calvert, Code and Provenzano, are also members of our board of directors. Our board of directors, including our executive management members and independent directors, is responsible for overseeing our executive management team in the execution of its responsibilities and for assessing our company’s approach to risk management. Our board of directors exercises these responsibilities on an ongoing basis as part of its meetings and through its committees. Each member of the management team has direct access to the other Board members, and our committees of our board of directors, to ensure that all risk issues are frequently and openly communicated. Our board of directors closely monitors the information it receives from management and provides oversight and guidance to our executive management team regarding the assessment and management of risk. For example, our board of directors regularly reviews our company’s critical strategic, operational, legal and financial risks with management to set the tone and direction for ensuring appropriate risk taking within the business.

Family Relationships

There are no family relationships among the directors and executive officers of our company.

Our company recognizes compensation expense for stock option awards on a straight-line basis over the applicable service period of the award, which is the vesting period. Share-based compensation expense is based on the grant date fair value estimated using the Black-Scholes method. The amounts in the “Stock Awards” and “Option Awards” columns reflect the aggregate fair value of awards of stock or options calculated as of the grant date. These amounts do not represent cash paid to or realized by any of the recipients during the years indicated.

In 2017 and 2018 the employment agreement for Mr. Calvert provided for a base salary of $288,603 and other compensation for health insurance and an automobile allowance.

Calvert, 1,500,000 shares of common stock, subject to a “lock-up agreement” whereby the shares remain unvested until the occurrence of certain events. As no such events occurred during 2017, and thus no shares vested, the value of the award in 2017 was recorded as zero. (See “Employment Agreements— Dennis P. Calvert ” and “Outstanding Equity Awards at Fiscal Year-End” below for more details.)

On May 2, 2017, pursuant to his employment agreement, we granted to our president, Dennis P. Calvert, an option to purchase 3,731,322 shares of the Company’s common stock.

Employment Agreements

Dennis P. Calvert

On May 2, 2017, BioLargo, Inc. (the “Company”) and its President and Chief Executive Officer Dennis P. Calvert entered into an employment agreement (the “Calvert Employment Agreement”), replacing in its entirety the previous employment agreement with Mr. Calvert dated April 30, 2007.

The Calvert Employment Agreement provides that Mr. Calvert will continue to serve as the President and Chief Executive Officer of the Company and receive base compensation equal to his current rate of pay of $288,603 annually. In addition to this base compensation, the agreement provides that he is eligible to participate in incentive plans, stock option plans, and similar arrangements as determined by the Company’s Board of Directors, health insurance premium payments for himself and his immediate family, a car allowance of $800 per month, paid vacation of four weeks per year, and bonuses in such amount as the Compensation Committee may determine from time to time.

Table of Contents

The Calvert Employment Agreement provides that Mr. Calvert will be granted an option (the “Option”) to purchase 3,731,322 shares of the Company’s common stock. The Option shall be a non-qualified stock option, exercisable at $0.45 per share, which represents the market price of the Company’s common stock as of the date of the agreement, exercisable for ten years from the date of grant and vesting in equal increments over five years. Notwithstanding the foregoing, any portion of the Option which has not yet vested shall be immediately vested in the event of, and prior to, a change of control, as defined in the Calvert Employment Agreement. The agreement also provides for a grant of 1,500,000 shares of common stock, subject to the execution of a “lock-up agreement” whereby the shares remain unvested unless and until the earlier of (i) a sale of the Company, (ii) the successful commercialization of the Company’s products or technologies as demonstrated by its receipt of at least $3,000,000 in cash, or the recognition of $3,000,000 in revenue, over a 12-month period from the sale of products and/or the license of technology, and (iii) the Company’s breach of the employment agreement resulting in his termination. The Option contains the other terms standard in option agreements issued by the Company, including provisions for a cashless exercise.

The Calvert Employment Agreement has a term of five years, unless earlier terminated in accordance with its terms. The Calvert Employment Agreement provides that Mr. Calvert’s employment may be terminated by the Company due to his death or disability, for cause, or upon a merger, acquisition, bankruptcy or dissolution of the Company. “Disability” as used in the Calvert Employment Agreement means physical or mental incapacity or illness rendering Mr. Calvert unable to perform his duties on a long-term basis (i) as evidenced by his failure or inability to perform his duties for a total of 120 days in any 360-day period, or (ii) as determined by an independent and licensed physician whom Company selects, or (iii) as determined without recourse by the Company’s disability insurance carrier. “Cause” means that Mr. Calvert has (i) engaged in willful misconduct in connection with the Company’s business; or (ii) been convicted of, or plead guilty or nolo contendre in connection with, fraud or any crime that constitutes a felony or that involves moral turpitude or theft. If Mr. Calvert’s employment is terminated due to merger or acquisition, then he will be eligible to receive the greater of (i) one year’s compensation plus an additional one half year for each year of service since the effective date of the employment agreement or (ii) one year’s compensation plus an additional one half year for each year remaining in the term of the agreement. Otherwise, he is only entitled to receive compensation due through the date of termination.

The Calvert Employment Agreement requires Mr. Calvert to keep certain information confidential, not to solicit customers or employees of the Company or interfere with any business relationship of the Company, and to assign all inventions made or created during the term of the Calvert Employment Agreement as “work made for hire”.

Kenneth R. Code

We entered into an employment agreement dated as of April 29, 2007 with Mr. Code, our Chief Science Officer (the “Code Employment Agreement”), which we amended on December 28, 2012 such that his salary will remain at $288,603, the level paid in April 2012, with no further automatic increases. The Code Employment Agreement can automatically renew for one year periods on April 29th of each year but may be terminated “without cause” at any time upon 120 days’ notice, and upon such termination, Mr. Code would not receive the severance originally provided for. All other terms in the 2007 agreement remain the same in the Code Employment Agreement.

In addition, Mr. Code will be eligible to participate in incentive plans, stock option plans, and similar arrangements as determined by our board of directors. When such benefits are made available to our senior employees, Mr. Code is also eligible to receive health insurance premium payments for himself and his immediate family, a car allowance of $800 per month, paid vacation of four weeks per year plus an additional two weeks per year for each full year of service during the term of the agreement up to a maximum of 10 weeks per year, life insurance equal to three times his base salary and disability insurance.

The Code Employment Agreement further requires Mr. Code to keep certain information confidential, not to solicit customers or employees of our company or interfere with any business relationship of our company, and to assign all inventions made or created during the term of the Code Employment Agreement as “work made for hire”.

Charles K. Dargan II

Charles K. Dargan, II has served as our Chief Financial Officer since February 2008 pursuant to an engagement agreement with his company, CFO 911, that has been renewed each year. For the renewal effective February 1, 2015, Mr. Dargan was compensated through the issuance of an option to purchase an additional 300,000 shares of our common stock, at an exercise price of $0.57 per share, to expire September 30, 2025, and vest over the term of the engagement with 120,000 shares vested as of September 30, 2015, and the remaining shares to vest 15,000 monthly, provided that the Engagement Extension Agreement with Mr. Dargan has not been terminated prior to each vesting date. Mr. Dargan receives no cash compensation from our company and continues to serve as our Chief Financial Officer.

On February 10, 2017, we and Mr. Dargan further extended his engagement agreement. The extension provides for an additional term to expire September 30, 2017 (the “Extended Term”), and is retroactively effective to the termination of the prior extension on October 1, 2016. This more recent extension again compensates Mr. Dargan through the issuance of an option to purchase 300,000 shares of the Company’s common stock. The strike price of the option is $0.69 per share, which is equal to the closing price of the Company’s common stock on February 10, 2017, expires February 10, 2027, and vests over the term of the engagement with 125,000 shares having vested as of February 10, 2017, and the remaining shares to vest 25,000 shares monthly beginning March 1, 2017, and each month thereafter, so long as his agreement is in full force and effect.

Table of Contents

On December 31, 2017, we and Mr. Dargan further extended his engagement agreement. The extension provides for an additional term to expire September 30, 2018 (the “Extended Term”), and is retroactively effective to the termination of the prior extension on October 1, 2017. This more recent extension again compensates Mr. Dargan through the issuance of an option to purchase 300,000 shares of the Company’s common stock. The strike price of the option is $0.39 per share, which is equal to the closing price of the Company’s common stock on December 29, 2017, expires December 31, 2027, and vests over the term of the engagement with 75,000 shares having vested as of December 31, 2017, and the remaining shares to vest 25,000 shares monthly beginning January 31, 2018, and each month thereafter, so long as his agreement is in full force and effect.

On January 16, 2019, we and Mr. Dargan formally agreed to extend his engagement agreement. The extension provides for an additional term to expire September 30, 2019, and is retroactively effective to the termination of the prior extension on September 30, 2018. Mr. Dargan has been serving as the Company’s Chief Financial Officer since such termination pursuant to the terms of the December 31, 2017 extension. This extension again compensates Mr. Dargan through the issuance of an option to purchase 300,000 shares of the Company’s common stock, at a strike price equal to the closing price of the Company’s common stock on January 16, 2019 of $0.223, to expire January 16, 2029, and to vest over the term of the engagement with 75,000 shares having vested as of December 31, 2018, and the remaining shares to vest 25,000 shares monthly beginning January 31, 2019, and each month thereafter, so long as the engagement agreement is in full force and effect. The Option was issued pursuant to the Company’s 2018 Equity Incentive Plan. The issuance of the Option is Mr. Dargan’s sole source of compensation for the extended term. As was the case in all prior terms of his engagement, there is no cash component of his compensation for the Extended Term. Mr. Dargan is eligible to be reimbursed for business expenses he incurs in connection with the performance of his services as the Company’s Chief Financial Officer (although he has made no such requests for reimbursement in the past). All other provisions of the Engagement Agreement not expressly amended pursuant to the Engagement Extension Agreement remain the same, including provisions regarding indemnification and arbitration of disputes.

Joseph Provenzano

Mr. Provenzano has served as Vice President of Operations since January 1, 2008, in addition to continuing to serve as our Corporate Secretary.

Mr. Provenzano’s employment agreement provided a base compensation in 2016 of $169,772 annually. Mr. Provenzano is also entitled to reimbursement for authorized expenses he incurs in the course of his employment. In addition, Mr. Provenzano is eligible to receive discretionary bonuses, participate in benefits made generally available to our employees and receive grants under our 2007 Equity Plan.

Mr. Provenzano’s employment agreement automatically renews each year unless we give at least 90 days’ notice of non-renewal, and contains additional provisions typical of an agreement of this nature.

Director Compensation

Each director who is not an officer or employee of our company receives an annual retainer of $60,000, paid in cash or shares of our common stock, or options to purchase our common stock (pursuant to a plan put in place by our board of directors), in our sole discretion. Historically, all but one director has received the entirety of his fees in the form of options to purchase stock, rather than cash. In addition, Mr. Marshall and Mr. Runyan each receive an additional $15,000 for their services as the chairman of the Audit Committee and chairman of the Compensation Committee, respectively. The following table sets forth information for the fiscal years ended December 31, 2018 regarding compensation of our non-employee directors. Our employee directors do not receive any additional compensation for serving as a director.

Limitation of Liability and Indemnification Matters

As permitted by the Delaware general corporation law, we have included a provision in our certificate of incorporation to eliminate the personal liability of our directors for monetary damages for breach of their fiduciary duties as directors, except for liability (i) for any breach of the director’s duty of loyalty to our company, (ii) for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law, (iii) under section 174 of the Delaware general corporation law or (iv) for any transaction from which the director derived an improper personal benefit. Our certificate of incorporation also provides that our company shall, to the full extent permitted by section 145 of the Delaware general corporation law, as amended from time to time, indemnify all persons whom it may indemnify pursuant thereto.

In addition, our Bylaws provide that we are required to indemnify our officers and directors even when indemnification would otherwise be discretionary, and we are required to advance expenses to our officers and directors as incurred in connection with proceedings against them for which they may be indemnified.

We may enter into indemnification agreements with our officers and directors containing provisions that are in some respects broader than the specific indemnification provisions contained in the Delaware general corporation law. The indemnification agreements would require us to indemnify our officers and directors against liabilities that may arise by reason of their status or service as officers and directors other than for liabilities arising from willful misconduct of a culpable nature, to advance their expenses incurred as a result of any proceeding against them as to which they could be indemnified, and to obtain our directors’ and officers’ insurance if available on reasonable terms. As of the date of this prospectus, our company has not entered into any indemnification agreement with any of its directors or officers, except for Mr. Strommen.

We have obtained directors’ and officers’ liability insurance in amounts comparable to other companies of our size and in our industry.

No pending litigation or proceeding involving a director, officer, employee or other agent of our company currently exists as to which indemnification is being sought. We are not aware of any threatened litigation that may result in claims for indemnification by any director, officer, employee or other agent of our company.

See “Disclosure of SEC Position on Indemnification for Securities Act Liabilities.”

Common Stock

Dividends . Each share of our common stock is entitled to receive an equal dividend, if one is declared. We cannot provide any assurance that we will declare or pay cash dividends on our common stock in the future. Any future determination to declare cash dividends will be made at the discretion of our board of directors, subject to applicable laws, and will depend on our financial condition, results of operations, capital requirements, general business conditions and other factors that our board of directors may deem relevant. Our board of directors may determine it to be necessary to retain future earnings (if any) to finance operations. See “Risk Factors” and “Dividend Policy.”

Liquidation . If our company is liquidated, then assets that remain (if any) after the creditors are paid and the owners of preferred stock receive liquidation preferences (as applicable) will be distributed to the owners of our common stock pro rata .

Voting Rights . Each share of our common stock entitles the owner to one vote. There is no cumulative voting. A simple majority can elect all of the directors at a given meeting, and the minority would not be able to elect any director at that meeting.

Preemptive Rights . Owners of our common stock have no preemptive rights. We may sell shares of our common stock to third parties without first offering such shares to current stockholders.

Redemption Rights. We do not have the right to buy back shares of our common stock except in extraordinary transactions, such as mergers and court approved bankruptcy reorganizations. Owners of our common stock do not ordinarily have the right to require us to buy their common stock. We do not have a sinking fund to provide assets for any buy back.

Conversion Rights . Shares of our common stock cannot be converted into any other kind of stock except in extraordinary transactions, such as mergers and court approved bankruptcy reorganizations.

Nonassessability . All outstanding shares of our common stock are fully paid and nonassessable.

Preferred Stock

Vista Capital Transaction

On December 18, 2017, we received $500,000, less $5,000 in legal fees, pursuant to a purchase agreement (the “Vista Agreement”) and a registration rights agreement (the “Vista RRA”) with Vista Capital Investments, LLC (“Vista Capital”), and issued a promissory note (the “Vista Note”) to Vista Capital in the aggregate principal amount of $500,000 at 5% annual interest. The Vista Note is convertible into shares of common stock of the Company at $0.394 per share, subject to the terms, and certain limitations and conditions, set forth in the Vista Agreement and Vista Note. Vista Capital may convert the Vista Note at any time. The Company may require the conversion of the Vista Note in the event the Company’s common stock has traded at a price per share of $0.75 or above for the ten trading days immediately preceding the mandatory conversion, and the shares underlying the conversion are subject to an effective registration statement filed with the SEC. The Vista Note was initially scheduled to mature on September 18, 2018. As set forth below, the Vista Note has been partially paid and the maturity date of the remaining principle amount has been extended.

Pursuant to the Vista Agreement, the Company issued 250,000 shares of common stock to Vista Capital as a commitment fee (the “Vista Commitment Shares”).

Under the Vista Note and Vista Agreement, the Company initially reserved 1,812,560 shares of common stock for issuance upon conversion of the Vista Note. Pursuant to the Vista RRA, the Company agreed to file a registration statement with the Securities and Exchange Commission (the “SEC”) registering all shares of common stock into which the Vista Note is convertible and the Vista Commitment Shares. The Vista Agreement allows for an adjustment to the number of Vista Commitment Shares in the event the closing price of our common stock, on the earlier of the date the registration statement is deemed effective and 20 trading days following the six-month anniversary of the Vista Note, is lower than the closing price on December 18, 2017 (which was $0.41). In such event, additional Vista Commitment Shares would be issued such that the aggregate Vista Commitment Shares issued have the same value as the shares issued on December 18, 2017.

Vista Capital represented to the Company, among other things, that it was an “accredited investor” (as such term is defined in Rule 501(a) of Regulation D under the Securities Act of 1933, as amended). The Vista Note, Vista Agreement, and the Vista RRA contain customary representations, warranties, agreements and conditions including indemnification rights and obligations of the parties.

Subsequent to the filing of the Registration Statement, in February 2018, the conversion rate of the Vista Note was reduced to $0.25 pursuant to the price protection features in the Note.

FirstFire Transaction

On January 16, 2018, we entered into a securities purchase agreement (the “FirstFire Agreement”) and a registration rights agreement (the “FirstFire RRA”) with FirstFire.

In conjunction with the execution of the FirstFire Agreement, and receipt of funds, we issued a convertible promissory note (the “FirstFire Note”) to FirstFire in the aggregate principal amount of $150,000 at 5% annual interest, which is convertible into shares of common stock of the Company at $0.394 per share, subject to the terms, and certain limitations and conditions, set forth in the FirstFire Agreement and the note. FirstFire may convert the FirstFire Note at any time. The Company may require the conversion of the FirstFire Note in the event the Company’s common stock has traded at a price per share of $0.75 or above for the ten trading days immediately preceding the mandatory conversion, and the shares underlying the conversion are subject to an effective registration statement filed with the SEC. The FirstFire Note matures on October 16, 2018.

Pursuant to the FirstFire Agreement, the Company issued 75,000 shares of common stock to FirstFire (the “FirstFire Commitment Shares”) as a commitment fee.

Pursuant to the FirstFire RRA, we agreed to file a registration statement with the SEC registering all shares of common stock into which the FirstFire Note is convertible and the FirstFire Commitment Shares. The FirstFire Agreement requires the issuance of additional FirstFire Commitment Shares in the event the closing price of our common stock, on the earlier of the date the registration statement is deemed effective and 20 trading days following the six-month anniversary of the FirstFire Note, is lower than the closing price on January 16, 2018. In such event, additional FirstFire Commitment Shares would be issued such that the aggregate FirstFire Commitment Shares issued have the same value as the shares issued on January 16, 2018.

The Company used the proceeds from the FirstFire Note for working capital and general corporate purposes.

Black Mountain and Gemini Transaction dated July 18, 2017

On July 18, 2017, we received $250,000 and issued convertible promissory notes (initially convertible at $0.42 per share) with a maturity date of July 8, 2017 to Black Mountain and Gemini in the aggregate principal amount of $280,000. Interest was charged upon issuance at 3% per annum. Concurrently, we issued these investors stock purchase warrants to purchase an aggregate 400,000 shares of our common stock, initially exercisable at $0.65 per share, which expire five years from the date of grant. Subject to certain exceptions, the exercise price of the stock purchase warrant may be adjusted downward in the event we sell our common stock or issue warrants at a lower price.

These warrants issued to Black Mountain and Gemini have since been repriced pursuant their terms (see “Warrant Reprice” below)

Warrant Reprice

⁽⁶⁾ The July 2017 warrants contain an exemption for shares issued in conversion of promissory notes, and thus the exercise price of the July 2017 warrants did not adjust.

PLAN OF DISTRIBUTION

The common stock offered by this prospectus is being offered by the selling stockholders. The common stock may be sold or distributed from time to time by a selling stockholder directly to one or more purchasers or through brokers, dealers, or underwriters who may act solely as agents at market prices prevailing at the time of sale, at prices related to the prevailing market prices, at negotiated prices, or at fixed prices, which may be changed. The sale of the common stock offered by this prospectus could be effected in one or more of the following methods:

●

ordinary brokers’ transactions;

●

transactions involving cross or block trades;

●

through brokers, dealers, or underwriters who may act solely as agents;

●

“at the market” into an existing market for the common stock;

●

in other ways not involving market makers or established business markets, including direct sales to purchasers or sales effected through agents;

●

in privately negotiated transactions; or

●

any combination of the foregoing.

In order to comply with the securities laws of certain states, if applicable, the shares may be sold only through registered or licensed brokers or dealers. In addition, in certain states, the shares may not be sold unless they have been registered or qualified for sale in the state or an exemption from the state’s registration or qualification requirement is available and complied with.

Each selling stockholder is an “underwriter” within the meaning of Section 2(a)(11) of the Securities Act.

Each selling stockholder has informed us that it intends to use an unaffiliated broker-dealer to effectuate all sales, if any, of the common stock that it may receive pursuant to the transactions described in the prospectus. Such sales will be made at prices and at terms then prevailing or at prices related to the then current market price. Each such unaffiliated broker-dealer will be an underwriter within the meaning of Section 2(a)(11) of the Securities Act. Each selling stockholder has informed us that each such broker-dealer will receive commissions from the selling stockholder that will not exceed customary brokerage commissions.

Brokers, dealers, underwriters or agents participating in the distribution of the shares as agents may receive compensation in the form of commissions, discounts, or concessions from the selling stockholder and/or purchasers of the common stock for whom the broker-dealers may act as agent. The compensation paid to a particular broker-dealer may be less than or in excess of customary commissions. Neither we nor the selling stockholders can presently estimate the amount of compensation that any agent will receive.

We know of no existing arrangements between any selling stockholder or any other stockholder, broker, dealer, underwriter or agent relating to the sale or distribution of the shares offered by this prospectus. At the time a particular offer of shares is made, a prospectus supplement, if required, will be distributed that will set forth the names of any agents, underwriters or dealers, any compensation from the selling stockholder, and any other required information.

We will pay the expenses incident to the registration, offering, and sale of the shares to the selling stockholders. We have agreed to indemnify the selling stockholders and certain other persons against certain liabilities in connection with the offering of shares of common stock offered hereby, including liabilities arising under the Securities Act or, if such indemnity is unavailable, to contribute amounts required to be paid in respect of such liabilities.

We have advised each selling stockholder that it is required to comply with Regulation M promulgated under the Exchange Act. With certain exceptions, Regulation M precludes the selling stockholder, any affiliated purchasers, and any broker-dealer or other person who participates in the distribution, from bidding for or purchasing, or attempting to induce any person to bid for or purchase, any security which is the subject of the distribution until the entire distribution is complete. Regulation M also prohibits any bids or purchases made in order to stabilize the price of a security in connection with the distribution of that security. All of the foregoing may affect the marketability of the securities offered by this prospectus.

This offering will terminate on the date that all shares offered by this prospectus have been sold by the selling stockholders.

Our common stock is quoted on the OTC Markets under the symbol “BLGO”.

Blue Sky Restrictions on Resale

If a selling stockholder desires to sell shares of our common stock under this prospectus in the United States, then such selling stockholder will also need to comply with state securities laws, also known as “Blue Sky laws,” with regard to secondary sales. All states offer a variety of exemptions from registration for secondary sales. Many states, for example, have an exemption for secondary trading of securities registered under Section 12(g) of the Exchange Act or for securities of issuers that publish continuous disclosure of financial and non-financial information in a recognized securities manual, such as Standard & Poor’s.

Any person who purchases shares of our common stock from a selling stockholder under this prospectus who then desires to sell such shares also will have to comply with Blue Sky laws regarding secondary sales.

DISCLOSURE OF SEC POSITION ON

INDEMNIFICATION FOR SECURITIES ACT LIABILITIES

Insofar as indemnification for liabilities arising under the Securities Act may be permitted to the directors, officers or persons controlling the registrant pursuant to the foregoing provisions, the registrant has been informed that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Securities Act and is therefore unenforceable.

In the event that a claim for indemnification against such liabilities (other than the payment by our company of expenses incurred or paid by such director, officer or controlling person of our company in the successful defense of any action, suit or proceeding) is asserted by any director, officer or controlling person of our company in connection with the securities being registered in the registration statement of which this prospectus is a part, the registrant will, unless in the opinion of counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by our company is against public policy as expressed in the Securities Act and will be governed by the final adjudication of such issue.

LEGAL OPINION

The validity of the shares covered by the registration statement of which this prospectus is a part has been passed upon for us by Wilson Bradshaw & Cao, LLP.

Report of Independent Registered Public Accounting Firm

To the Board of Directors and Stockholders

BioLargo, Inc. and Subsidiaries

Opinion on the Financial Statements

We have audited the accompanying consolidated balance sheets of BioLargo, Inc. and Subsidiaries (the “Company”) as of December 31, 2017 and 2018, and the related consolidated statements of operations, stockholders’ equity (deficit), and cash flows for each of the two years in the period ended December 31, 2018, and the related notes (collectively referred to as the “consolidated financial statements”). In our opinion, the consolidated financial statements present fairly, in all material respects, the consolidated financial position of the Company as of December 31, 2017 and 2018, and the consolidated results of its operations and its cash flows for each of the two years in the period ended December 31, 2018, in conformity with accounting principles generally accepted in the United States of America.

Going Concern

The accompanying consolidated financial statements have been prepared assuming that the Company will continue as a going concern. As discussed in Note 1 to the consolidated financial statements, the Company has experienced recurring losses, negative cash flows from operations, has limited capital resources, a net stockholders’ deficit, and significant debt obligations coming due in the near term. These matters raise substantial doubt about the Company’s ability to continue as a going concern. Management’s plans in regard to these matters are also described in Note 1. The consolidated financial statements do not include any adjustments that might result from the outcome of this uncertainty.

Basis for Opinion

These consolidated financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on the Company’s consolidated financial statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (“PCAOB”) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud. The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audits, we are required to obtain an understanding of internal control over financial reporting but not for the purpose of expressing an opinion on the effectiveness of the Company’s internal control over financial reporting. Accordingly, we express no such opinion.

Our audits included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures include examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. We believe that our audits provide a reasonable basis for our opinion.

Note 1. Business and Organization

Description of Business

BioLargo, Inc. delivers innovative and sustainable technology-based products and services, as well as environmental engineering expertise, across a broad range of industries with an overriding mission to “make life better” with a focus on clean water, clean air, and advanced wound care. Our business strategy is straightforward: we invent or acquire technologies that we believe have the potential to be disruptive in large commercial markets; we develop and validate these technologies to advance and promote their commercial success as we leverage our considerable scientific, engineering, and entrepreneurial talent; we then monetize these technical assets through a variety of business structures that may include licensure, joint venture, sale, spin off, or by deploying direct to market strategies.

Liquidity / Going concern

The accompanying consolidated financial statements have been prepared on a going concern basis, which contemplates the realization of assets and the settlement of liabilities and commitments in the normal course of our business. For the year ended December 31, 2018, we had a net loss of $10,696,000, used $3,891,000 cash in operations, and at December 31, 2018, we had a working capital deficit of $1,536,000, and current assets of $955,000. We do not believe gross profits will be sufficient to fund our current level of operations or pay our debt due prior to December 31, 2019, and will have to obtain further investment capital to continue to fund operations and seek to refinance our existing debt. We have been, and anticipate that we will continue to be, limited in terms of our capital resources. During the year ended December 31, 2018, we generated revenues of $1,364,000 through two subsidiaries (Odor-No-More and BLEST – see Note 2, “Business Segment Information”). Neither generated enough revenues to fund their operations, and thus in order for those two, and our other, business segments to continue to operate throughout 2018, we conducted private securities offerings. During the year ended December 31, 2018, we received $3,642,000 net proceeds from various private securities offerings, and ended the year with total cash and cash equivalents of $655,000. Our cash position as of date hereof is insufficient to pay our debt obligations due in April 2019, and thus we must either refinance or renegotiate these obligations. Our cash position is insufficient to maintain our current level of operations and research/development, and thus we will be required to raise substantial additional capital to continue to fund our operations in 2019, as well as our future business plans. We continue to raise money through private securities offerings (see Note 14), and continue to negotiate for more substantial financings from private and institutional investors. Although we engaged an investment banking firm and filed a registration statement to raise $7,500,000 in conjunction with an application for listing our common stock on the Nasdaq Capital Markets, no assurance can be made that we will move forward in the near future with that offering or our listing application. We may reconsider and postpone these efforts as management believes our current market capitalization does not reflect the true value of the Company or recognize the significant business opportunities that lie ahead. Our board intends to evaluate these and other factors, including the anticipated dilution to our stockholders of an offering of the size required to meet the initial and continued listing requirements. No assurance can be made of our success at raising money through private or public offerings, or of our intended listing on a national exchange. No assurance can be made of our success at raising money through private or public offerings, or of our intended listing on a national exchange.

The foregoing factors raise substantial doubt about our ability to continue as a going concern. Ultimately, our ability to continue as a going concern is dependent upon our ability to attract significant new sources of capital, attain a reasonable threshold of operating efficiencies and achieve profitable operations by licensing or otherwise commercializing products incorporating our technologies. The consolidated financial statements do not include any adjustments that might be necessary if we are unable to continue as a going concern.

Table of Contents

Organization

We are a Delaware corporation formed in 1991. We have five wholly-owned subsidiaries: BioLargo Life Technologies, Inc., organized under the laws of the State of California in 2006; Odor-No-More, Inc., organized under the laws of the State of California in 2009; BioLargo Water, Inc., organized under the laws of Canada in 2014; BioLargo Development Corp., organized under the laws of the State of California in 2016; and BioLargo Engineering Science and Technologies, LLC, organized under the laws of the State of Tennessee in 2017 (“BLEST”). Additionally, we own 42.3% of Clyra Medical Technologies, Inc. (“Clyra Medical”), organized under the laws of the State of California in 2012, and consolidate their financial statements (see Note 10).

Note 2. Summary of Significant Accounting Policies

Principles of Consolidation

The consolidated financial statements include the accounts of the Company, its wholly owned subsidiaries, and Clyra Medical. Management believes Clyra Medical’s financial statements are appropriately consolidated with that of the Company after reviewing the guidance of ASC Topic 810 , “Consolidation”, and concluding that BioLargo controls Clyra Medical. While BioLargo does not have voting interest control through a majority stock ownership of Clyra Medical (it owns 42.3% of the outstanding voting stock), it does exercise control under the “Variable Interest Model.” There is substantial board overlap, BioLargo is the primary beneficiary since it has the power to direct Clyra Medical’s activities that most significantly impact Clyra Medical’s performance, and it has the obligation to absorb losses or receive benefits (through royalties and licensing) that could be potentially significant to Clyra Medical. Biolargo has consolidated Clyra Medical’s operations for all periods presented. (See Note 10).

All intercompany accounts and transactions have been eliminated.

Foreign Currency

The Company has designated the functional currency of Biolargo Water, Inc., our Canadian subsidiary, to be the Canadian dollar. Therefore, translation gains and losses resulting from differences in exchange rates are recorded in accumulated other comprehensive income.

Cash and Cash Equivalents

The Company considers all highly liquid investments with maturities of three months or less when acquired to be cash equivalents. Substantially all cash equivalents are held in short-term money market accounts at one of the largest financial institutions in the United States. From time to time, our cash account balances are greater than the Federal Deposit Insurance Corporation insurance limit of $250,000 per owner per bank, and during such times, we are exposed to credit loss for amounts in excess of insured limits in the event of non-performance by the financial institution. We do not anticipate non-performance by our financial institution.

As of December 31, 2017 and 2018, our cash balances were made up of the following (in thousands):

	2017		2018
Biolargo, Inc. and wholly owned subsidiaries	$	462	$	193
Clyra Medical Technologies, Inc.		528		462
Total	$	990	$	655

Accounts Receivable

Trade accounts receivable are recorded net of allowances for doubtful accounts. Estimates for allowances for doubtful accounts are determined based on payment history and individual customer circumstances. The allowance for doubtful accounts as of December 31, 2017 was $3,000. As of December 31, 2018, although our accounts receivable balance had increased, such increase was due to increased sales, and based on our history of collections, we decreased the allowance for doubtful accounts to zero.

F-8

Table of Contents

Credit Concentration

We have a limited number of customers that account for significant portions of our revenue. During the years ended December 31, 2017 and 2018, we had three and one customer that each accounted for more than 10% of consolidated revenues in the respective periods, as follows:

	2017			2018
Customer A		27	%	<10		%
Customer B		24	%		33	%
Customer C		11	%	<10		%

We had five customers that each accounted for more than 10% of consolidated accounts receivable at December 31, 2017 and two customers at December 31, 2018 as follows:

	2017			2018
Customer X		19	%		12	%
Customer Y		10	%		31	%
Customer Z		12	%	<10		%
Customer AA		12	%	<10		%
Customer BB		10	%	<10		%

Inventory

Inventories are stated at the lower of cost or net realizable value using the average cost method. The allowance for obsolete inventory as of December 31, 2017 and 2018 was $3,000. As of December 31, 2017 and 2018, inventories consisted of (in thousands):

	2017		2018
Raw material	$	34	$	14
Finished goods		20		12
Total	$	54	$	26

Other Assets

Other Assets consisted of security deposits of $35,000 related to our business offices.

Impairment

Long-lived and definite lived intangible assets are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. If the sum of the expected future undiscounted cash flows from the use of the asset and its eventual disposition is less than the carrying amount of the asset, then an impairment loss is recognized. The impairment loss is measured based on the fair value of the asset. Any resulting impairment is recorded as a reduction in the carrying value of the related asset in excess of fair value and a charge to operating results. For the years ended December 31, 2017 and 2018, management determined that there was no impairment of its long-lived assets.

Earnings (Loss) Per Share

We report basic and diluted earnings (loss) per share (“EPS”) for common and common share equivalents. Basic EPS is computed by dividing reported earnings by the weighted average shares outstanding. Diluted EPS is computed by adding to the weighted average shares the dilutive effect if stock options and warrants were exercised into common stock. For the years ended December 31, 2017 and 2018, the denominator in the diluted EPS computation is the same as the denominator for basic EPS due to the anti-dilutive effect of the warrants and stock options on the Company’s net loss.

F-9

Table of Contents

Use of Estimates

The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements, and revenues and expenses during the period reported. Actual results could differ from those estimates. Estimates are used when accounting for stock-based transactions, debt transactions, derivative liabilities, allowance for bad debt, asset depreciation and amortization, among others.

The methods, estimates and judgments we use in applying these most critical accounting policies have a significant impact on the results of our financial statements.

Share-Based Compensation Expense

We recognize compensation expense for stock option awards on a straight-line basis for employees over the applicable service period of the award, which is the vesting period. We recognize compensation expense for stock option awards for non-employees at the fair value on the grant date. Generally, the options issued to non-employees have been earned upon issuance. For the instances that options are issued to non-employees with a vesting schedule, the fair value is recorded on each vesting date. Share-based compensation expense is based on the grant date fair value estimated using the Black-Scholes Option Pricing Model.

For stock and stock options issued to consultants and other non-employees for services, the Company measures and records an expense as of the earlier of the date at which either: a commitment for performance by the non-employee has been reached or the non-employee’s performance is complete. The equity instruments are measured at the current fair value, and for stock options, the instruments are measured at fair value using the Black Scholes option model.

For equity instruments issued and outstanding where performance is not complete, but the instrument has been recorded, those instruments are measured again at their then current fair market values at each of the reporting dates (they are “marked-to market”) until the performance and the contract are complete.

The following methodology and assumptions were used to calculate share-based compensation for the years ended December 31, 2017 and 2018:

	2017								2018
	Non Plan				2007 Plan				Non Plan				20 18 Plan
Risk free interest rate	2.29	–	2.43	%	2.31	–	2.40	%	2.43	–	2.91	%	2.89	–	2.91	%
Expected volatility	563	–	601	%	578	–	601	%	538	–	563	%	489	–	548	%
Expected dividend yield		—				—				—				—
Forfeiture rate		—				—				—				—
Life in years		7				5				7				7

Expected price volatility is the measure by which our stock price is expected to fluctuate during the expected term of an option. Expected volatility is derived from the historical daily change in the market price of our common stock, as we believe that historical volatility is the best indicator of future volatility.

The risk-free interest rate used in the Black-Scholes calculation is based on the prevailing U.S. Treasury yield as determined by the U.S. Federal Reserve. We have never paid any cash dividends on our common stock and do not anticipate paying cash dividends on our common stock in the foreseeable future.

F-10

Table of Contents

Historically, we have not had significant forfeitures of unvested stock options granted to employees and Directors. A significant number of our stock option grants are fully vested at issuance or have short vesting provisions. Therefore, we have estimated the forfeiture rate of our outstanding stock options as zero.

Warrants

Warrants issued with our convertible and non-convertible debt instruments are accounted for under the fair value and relative fair value method.

Non-Cash Transactions

We have established a policy relative to the methodology to determine the value assigned to each intangible we acquire, and/or services or products received for non-cash consideration of our common stock. The value is based on the market price of our common stock issued as consideration, at the date of the agreement of each transaction or when the service is rendered or product is received.

Revenue Recognition

We adopted ASU 2014-09, “Revenue from Contracts with Customers”, Topic 606, on January 1, 2018. The guidance focuses on the core principle for revenue recognition.

Step 1: Identify the contract(s) with a customer.

Step 2: Identify the performance obligations in the contract.

Step 3: Determine the transaction price.

Step 4: Allocate the transaction price to the performance obligations in the contract.

Step 5: Recognize revenue when (or as) the entity satisfies a performance obligation.

Government Grants

We have been awarded multiple research grants from the Canadian National Research Institute – Industrial Research Assistance Program (NRC-IRAP) and the National Science and Engineering Research Council of Canada (NSERC). The grants received are considered other income and are included in our consolidated statements of operations. We received our first grant in 2015 and have been awarded over 65 grants totaling over $3.6 million. Some of the funds from these grants are given directly to third parties (such as the University of Alberta or a third-party research scientist) to support research on our technology. The grants have terms generally ranging between six and eighteen months and support a majority, but not all, of the related research budget costs. This cooperative research allows us to utilize (i) a depth of resources and talent to accomplish highly skilled work, (ii) financial aid to support research and development costs, (iii) independent and credible validation of our technical claims.

The grants typically provide for (i) recurring monthly amounts, (ii) reimbursement of costs for research talent for which we invoice to request payment, and (iii) ancillary cost reimbursement for research talent travel related costs. All awarded grants have specific requirements on how the money is spent, typically to employ researchers. None of the funds may be used for general administrative expenses or overhead in the United States. These grants have substantially increased our level of research and development activities in Canada. We continue to apply for Canadian government and agency grants to fund research and development activities. Not all of our grant applications have been awarded, and no assurance can be made that any pending grant application, or any future grant applications, will be awarded.

Income Taxes

The asset and liability approach is used to recognize deferred tax assets and liabilities for the expected future tax consequences of temporary differences between the carrying amounts and the tax bases of asset and liabilities. Deferred tax assets and liabilities are determined based on the differences between financial reporting and tax bases of assets and liabilities and are measured using the enacted tax rates and laws that will be in effect when the differences are expected to reverse. The effect on deferred tax asset and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date.

We account for uncertainties in income tax law under a comprehensive model for the financial statement recognition, measurement, presentation and disclosure of uncertain tax positions taken or expected to be taken in income tax returns as prescribed by generally accepted accounting principles (“GAAP”). Under GAAP, the tax effects of a position are recognized only if it is “more-likely-than-not” to be sustained by the taxing authority as of the reporting date. If the tax position is not considered “more-likely-than-not” to be sustained, then no benefits of the position are recognized.

F-12

Table of Contents

Fair Value of Financial Instruments

Management believes the carrying amounts of the Company’s financial instruments (excluding debt and equity instruments) as of December 31, 2017 and 2018 approximate their respective fair values because of the short-term nature of these instruments. Such instruments consist of cash, accounts receivable, prepaid assets, accounts payable, lines of credit, and other assets and liabilities.

Tax Credits

Our research and development activities in Canada may entitle our Canadian subsidiary to claim benefits under the “Scientific Research and Experimental Development Program”, a Canadian federal tax incentive program designed to encourage Canadian businesses of all sizes and in all sectors to conduct research and development in Canada. Benefits under the program include credits to taxable income. If our Canadian subsidiary does not have taxable income in a reporting period, we instead receive a tax refund from the Canadian Revenue Authority. Those refunds are classified in Other Income on our Consolidated Statement of Operations and Comprehensive Loss.

Recent Accounting Pronouncements

In August 2018, the FASB issued Accounting Standards Update No. 2018-13, “Fair Value Measurement (Topic 820), Disclosure Framework—Changes to the Disclosure Requirements for Fair Value Measurement.” The amendments in this update modify the disclosure requirements on fair value measurements in Topic 820, Fair Value Measurement.

The amendments in this update are effective for public business entities for fiscal years beginning after December 15, 2019, including interim periods within that fiscal year. Management has not concluded its evaluation of the guidance. Its initial analysis is that it does not believe the new guidance will substantially impact the Company’s financial statements.

In June 2018, The FASB issued Accounting Standards Update No. 2018-07, “Compensation – Stock Compensation (topic 718): Improvements to Nonemployee Share-Based Payment Accounting”. The amendments in this update expand the scope of Topic 718 to include share-based payment transactions for acquiring goods and services from nonemployees. An entity should apply the requirements of Topic 718 to nonemployee awards except for specific guidance on inputs to an option pricing model and the attribution of cost (that is, the period of time over which share-based payment awards vest and the pattern of cost recognition over that period). The amendments specify that Topic 718 applies to all share-based payment transactions in which a grantor acquires goods or services to be used or consumed in a grantor’s own operations by issuing share-based payment awards. The amendments also clarify that Topic 718 does not apply to share-based payments used to effectively provide (1) financing to the issuer or (2) awards granted in conjunction with selling goods or services to customers as part of a contract accounted for under Topic 606, Revenue from Contracts and Customers. The amendments in this update are effective for public business entities for fiscal years beginning after December 15, 2018, including interim periods within that fiscal year. Management has not concluded its evaluation of the guidance. Its initial analysis is that the new guidelines would likely decrease the stock compensation expense, but not so as to substantially impact the Company’s financial statements.

In February 2016, the FASB issued ASU Update No. 2016-02, “Leases,” which will require lessees to recognize most leases on their balance sheets as a right-of-use asset with a corresponding lease liability, and lessors to recognize a net lease investment. Additional qualitative and quantitative disclosures will also be required. We will adopt this standard effective January 1, 2019 using the modified retrospective transition method approved by the FASB in July 2018. Management believes the adoption of the new standard will gross up assets and liabilities; however, we do not believe there will be a material impact on our states of operations.

Note 3. Acquisition of In-process Research and Development

On September 26, 2018, BioLargo and Clyra Medical entered into a transaction whereby BioLargo would acquire the intangible assets of Scion Solutions, LLC (“Scion”), and in particular its in-process research and development of the “SkinDisc,” a method for treating advanced hard-to-treat wounds including diabetic ulcers. In addition to a pending patent application, the assets include the technical know-how and data developed by the Scion team.

The consideration provided to Scion is subject to an escrow agreement dated September 26, 2018 (“Escrow Agreement”) and earn out provisions and includes: (i) 21,000 shares of the Clyra Medical common stock; (ii) 10,000 shares of Clyra Medical common stock redeemable for 7,142,858 BioLargo common shares (detailed below); and (iii) a promissory note in the principal amount of $1,250,000 to be paid through new capital investments and revenue, as detailed below. This consideration was initially held in escrow pending Clyra Medical raising $1 million “base capital” to fund its business operations.

On December 17, 2018, the parties entered into a closing agreement (“Closing Agreement”) reflecting the satisfaction of the obligation to raise $1 million “base capital”; at that time, one-half of the shares of Clyra Medical common stock exchanged for the Scion assets were released to Scion. The remaining Clyra Medical common shares (a total of 15,500 shares) remain subject to the Escrow Agreement’s performance metrics, each vesting one-fifth of the remaining shares of common stock: (a) notification of FDA premarket clearance of certain orthopedics products, or recognition by Clyra Medical of $100,000 gross revenue; (b) the recognition by Clyra Medical of $100,000 in aggregate gross revenue; (c) the granting of all or any part of the patent application for the SkinDisc product, or recognition by Clyra Medical of $500,000 in gross revenue; (d) recognition by Clyra Medical of $1 million in aggregate gross revenue; and (e) recognition by Clyra Medical of $2 million in gross revenue.

The promissory note in the principal amount of $1,250,000 issued by Clyra Medical to Scion on September 26, 2018 accrues interest at the rate of 5%. Principal and interest due under the note are to be paid periodically at a rate of 25% of investment proceeds received by Clyra Medical. If the note is not paid off within 18 months after the date of issuance, it is automatically extended for additional 12-month periods until the note is repaid in full. Payments after the initial 18-month maturity date are required to be made in annual installments in an amount equal to the greater of (i) 25% of investment proceeds received during the 12-month period, and (ii) 5% of Clyra Medical’s gross revenues.

Immediately following Clyra Medical’s purchase of Scion’s intangible assets, Clyra Medical sold to BioLargo the assets, along with 12,755 Clyra Medical common shares. In exchange, BioLargo issued Clyra Medical 7,142,858 shares of BioLargo common stock. Concurrently, BioLargo licensed back to Clyra Medical the Scion assets. Scion may exchange its 10,000 Clyra Medical common shares for the 7,142,858 shares of BioLargo common stock issued to Clyra Medical, subject to the escrow and earn-out provisions described above. As of December 31, 2018, per the Closing Agreement, one-half of these shares have been earned and thus may be redeemed, and one-half remain subject to the earn-out provisions. The fair value of the 7,142,858 BioLargo shares is $1,286,000, and one-half of this value is included on our December 31, 2018 balance sheet as (i) “In-process research and development” asset, and (ii) a “Clyra Medical shareholder” liability.

Note 4. Lincoln Park Financing

On August 25, 2017, we entered into a stock purchase agreement (“LPC Purchase Agreement”) with Lincoln Park Capital Fund, LLC (“Lincoln Park”), pursuant to which Lincoln Park agreed to purchase from us at our request up to an aggregate of $10 million of our common stock (subject to certain limitations) from time to time over a period of three years. Concurrently, we entered into a registration rights agreement with Lincoln Park (“LPC RRA”), pursuant to which we were required to file with the Securities and Exchange Commission (“SEC”) a registration statement on Form S-1 to register for resale under the Securities Act of 1933, as amended, the shares of common stock that have been or may be issued to Lincoln Park under the LPC Purchase Agreement. The registration statement was filed, and on September 22, 2017, it was deemed effective by the SEC. The LPC Purchase Agreement allows us, from time to time and at our sole discretion, to direct Lincoln Park to purchase shares of our common stock, subject to limitations in both volume and dollar amount. The volume of shares is limited to a maximum of 50,000 shares if our stock closes at less than $0.50 per share, 75,000 if it closes from $0.50 to $0.74 per share, 100,000 if it closes from $0.75 to $1.24 per share, and 200,000 if it closes at or above $1.25 per share. The maximum dollar amount for any single purchase is $500,000. There are no trading volume requirements under the LPC Purchase Agreement, and we alone control the timing and amount of any sales of our common stock to Lincoln Park. The purchase price of the shares that may be sold to Lincoln Park under the Purchase Agreement is the lower of (i) the lowest sale price on the date of purchase, or (ii) the average of the three lowest closing prices in the prior 12 business days. The purchase price per share will be equitably adjusted for any reorganization, recapitalization, non-cash dividend, stock split, or other similar transaction occurring during the business days used to compute such price. We may at any time in our sole discretion terminate the LPC Purchase Agreement without fee, penalty or cost upon one business day notice. There are no restrictions on future financings, rights of first refusal, participation rights, penalties or liquidated damages in the LPC Purchase Agreement or LPC RRA other than a prohibition on entering into a “Variable Rate Transaction,” as defined in the Purchase Agreement. Lincoln Park may not assign or transfer its rights and obligations under the Purchase Agreement.

Table of Contents

In consideration for entering into the LPC Purchase Agreement, on August 25, 2017, we issued to Lincoln Park 488,998 shares of common stock as an “initial commitment fee.” For no additional consideration, when and if Lincoln Park purchases (at the Company’s discretion) any portion of the $10 million aggregate commitment, we are required to issue up to 488,998 shares, pro-rata, as “additional commitment shares”. For example, if we elect, at our sole discretion, to require Lincoln Park to purchase $25,000 of our stock, then we would issue 1,222 additional commitment shares, which is the product of $25,000 (the amount we have elected to sell) divided by $10 million (total amount we can sell Lincoln Park pursuant to the LPC Purchase Agreement) multiplied by 488,998 (the total number of additional commitment shares). The additional commitment shares will only be issued pursuant to this formula as and when we elect at our discretion to sell stock to Lincoln Park.

During the years ended December 31, 2017 and 2018, our transactions pursuant to the Purchase Agreement with Lincoln Park totaled:

	Year ended December 31, 2017		Year ended December 31, 2018
Shares sold to Lincoln Park		1,199,991		2,891,749
Additional Commitment Shares issued to Lincoln Park		24,991		41,016
Total shares issued to Lincoln Park:		1,224,982		2,932,765

Gross proceeds to BioLargo:	$	511,000	$	839,000

We recorded the stock sales in our equity statement and the additional shares issued reduce the deferred offering costs.

For the years ended December 31, 2017 and 2018 we recorded $3,862,000 and $3,494,000 of interest expense related to the amortization of discounts on convertible notes payable and coupon interest from our convertible notes and line of credit.

Conversion of Debt Obligations

Of the $6,788,000 in debt obligations outstanding as of December 31, 2017, during the year ended December 31, 2018, $6,190,000 were converted into shares of our common stock.

Early Conversion of Unit Notes

In May 2018, prior to their maturity dates, we issued 17,255,811 shares of our common stock in satisfaction of $4,626,000 of convertible promissory notes issued in our “unit” offerings at varying conversion prices, maturing on the following dates (in thousands):

These conversions were voluntary on the part of the noteholders and prior to the various maturity dates on notes that were issued in prior “unit” offerings conducted by the Company (2015 Unit Offering, Winter 2016 Unit Offering, and Summer 2017 Unit Offering). We offered these noteholders incentives to convert their notes early. Noteholders with conversion prices of $0.25 and $0.30 were offered incentive shares equal to one and one-half times the number of shares issuable for the payment of interest that would accrue from the last interest payment date of March 20, 2018, through the maturity of the note, at a fixed price of $0.25 per share (for example, a note that would have yielded $1,000 in interest, would receive 1,000 times 1.5 divided by 0.25 equals 6,000 incentive shares). We offered holders of notes with conversion prices higher than $0.30 the ability to reduce their conversion price to $0.30 by paying additional funds equal to six percent or twenty percent of their original investment (6% for notes with original conversion prices of $0.35, and 20% for notes with original conversion prices of $0.55 and $0.57). The additional funds did not increase the amount of the note payable, nor did the reduced conversion price affect the number of shares purchasable under the warrant issued with their “unit” investment. Holders of 40 notes elected to pay an aggregate $357,000 to reduce the conversion prices of their notes to $0.30. As a result of the reduction in conversion prices, an additional 2,749,197 shares were issuable pursuant to the notes upon conversion. The fair value of these additional shares was $632,000. Additional interest expense of $276,000 was recorded as part of the debt conversion and is the amount by which the fair value of the additional shares exceeded the cash received by the Company. Holders of 41 notes with original conversion prices of $0.30 and $0.25 elected to convert early and received 966,318 additional “incentive shares” for their agreement to do so.

Conversion of 2015 Unit Offering Notes at Maturity

On June 1, 2018, we elected to convert the $822,000 outstanding promissory notes remaining in our 2015 Unit Offering on their June 1, 2018 maturity date into 2,488,819 shares of our common stock. Of the shares issued, 2,411,004 were issued in satisfaction of principal amounts due on notes with conversion prices of $0.25, $0.35, and $0.55, and 77,815 shares were issued in satisfaction of $20,000 of accrued and unpaid interest.

Conversion of one-year convertible notes, mature July 18, 2018

On July 2, 2018, the holders of two one-year notes in the aggregate principal amount of $280,000 which were due to mature on July 18, 2018, tendered an offer to the Company to convert 100% of the balance due on the outstanding notes into shares of our common stock in lieu of receiving cash. We accepted the offer and agreed to convert the principal balance of $280,000 and $9,000 in outstanding interest into an aggregate 1,153,600 shares of our common stock, at $0.25 per share.

Conversion of convertible note, matures October 16, 2018 (FirstFire)

On January 16, 2018, we entered into a securities purchase agreement (the “FirstFire Purchase Agreement”) and a registration rights agreement (the “FirstFire RRA”) with FirstFire Global Opportunity Fund, LLC (“FirstFire”), and issued a nine-month promissory note (the “FirstFire Note”) in the principal amount of $150,000 at 5% annual interest convertible into shares of common stock of the Company at $0.394 per share, subject to the terms, and certain limitations and conditions set forth in the FirstFire Purchase Agreement and FirstFire Note.

Pursuant to the FirstFire Purchase Agreement, the Company issued 75,000 shares of common stock to FirstFire as a commitment fee (the “FirstFire Commitment Shares”) at $0.39 per share and $29,000 is recorded as a discount on convertible notes and will amortize to interest expense over the term of the note. Pursuant to the FirstFire RRA, because our common stock traded lower as of the date the FirstFire Commitment Shares were registered ($0.3147 on February 8, 2018), we issued 36,536 additional commitment shares of our common stock and $11,000 is recorded as additional discount on convertible notes and will amortize to interest expense over the term of the note.

F-17

Table of Contents

The FirstFire Note contains a price protection provision such that if we issue a security with any term more favorable to the holder of such security that was not similarly provided in the FirstFire Note, then the Company shall notify FirstFire of such additional or more favorable term and such term, at its option, shall become a part of the FirstFire Note. As a result of our sale of common stock at $0.25, the conversion price of the FirstFire Note was reduced from $0.394 to $0.25.

In June 2018, FirstFire elected to convert $96,000 of the outstanding principal balance of the FirstFire Note and we issued 383,047 shares, plus 11,902 shares for outstanding interest. On July 15, 2018, FirstFire elected to convert the remaining outstanding principal amount of $54,000, plus interest, and we issued 217,960 shares at $0.25 per share.

Notes payable, mature January 5, 2019

On September 19, 2018, we received $400,000 and issued promissory notes originally due January 5, 2019 and incurring interest at an annual rate of 12%, and stock purchase warrants (see Note 7), to two investors. We exercised our option to extend the maturity date of these notes by 60 days by giving written notice on January 3, 2019, and as a result the principal amount of the notes increased by 10%, effective as of the date of the notice, and amended the notes to further extend the maturity date (see Note 14 “Subsequent Events”).

Convertible Note, matures January 11, 2019 (Triton)

On October 16, 2018, we entered into a Securities Purchase Agreement (“Triton Purchase Agreement”) with Triton Fund, LP (“Triton”) for a $225,000 bridge loan, and issued a promissory note in the principal amount of $300,000 (the “Triton Note”). The Triton Note incurs interest at an annual rate of 5%, and was scheduled to mature January 11, 2019. We agreed to repay the note through any financing we close in excess of $3 million. The $75,000 original issue discount is recorded as a discount on our convertible note and will be amortized to interest expense over the term of the note.

In addition to the note, we issued a stock purchase warrant to Triton (the “Triton Warrant”) allowing Triton to purchase up to an aggregate 1 million shares of our common stock for $0.25 per share, until October 12, 2023 (see Note 7).

In addition to the foregoing, we donated 150,000 shares of our common stock to the student-run Triton Fund, LLC. The closing price of our common stock on the date of grant was $0.28 and we recorded $42,000 of interest expense.

On January 8, 2019, we paid the Triton Note in full (see Note 14 “Subsequent Events”).

Convertible Note, matures April 15, 2019 (Vista Capital)

On December 18, 2017, we received $500,000 pursuant to a securities purchase agreement (the “Vista Purchase Agreement”) and a registration rights agreement (the “Vista RRA”) with Vista Capital Investments, LLC (“Vista Capital”), and issued a convertible promissory note (the “Vista 2017 Note”) in the aggregate principal amount of $500,000 at 5% annual interest, which was originally convertible into shares of common stock of the Company at $0.394 per share, subject to the terms, and certain limitations and conditions, set forth in the Vista Purchase Agreement and Vista Note. The Vista 2017 Note was originally scheduled to mature on September 18, 2018.

Pursuant to the Vista RRA, we filed a registration statement to register the shares of common stock into which the Vista 2017 Note is convertible, and the 250,000 shares issued as a commitment fee, which was recorded as a discount on convertible notes in the amount of $99,000 and was amortized to interest expense over the term of the note. The registration statement was deemed effective by the SEC on February 8, 2018. Because the closing price of our common stock was lower on the date the registration of these shares was deemed effective, we were required to issue an additional 140,849 shares of our common stock as additional commitment shares. The beneficial conversion feature resulted in a $20,000 relative fair value recorded as an additional discount. The discount was amortized monthly to interest expense through September 18, 2018.

F-18

Table of Contents

The Vista 2017 Note contains a price protection provision such that if we issue a security with any term more favorable to the holder of such security that was not similarly provided in the Vista 2017 Note, then we shall notify Vista Capital of such additional or more favorable term and such term, at its option, shall become a part of the Vista 2017 Note. As a result of our sale of common stock at $0.25, the conversion price of the Vista 2017 Note was reduced from $0.394 to $0.25.

In June 2018, Vista Capital elected to convert $52,000 of the outstanding principal and interest balance of the Vista Note and we issued 208,100 shares of our common stock.

On September 12, 2018, Vista Capital agreed to extend the maturity date of the Vista 2017 Note to December 18, 2018. In return, we increased the principal outstanding balance by 20% or $92,000. In addition, we issued the note holder a warrant to purchase 1,812,000 shares of our common stock at $0.25 per share, which was fair valued using the Black Scholes option model at $488,000 (see Note 6). We accounted for this as a modification of the note. Per the guidance of ASC 470-50, Debt Modifications and Extinguishments, modified terms are considered substantially different if the present value of the cash flows after modification differ by at least 10% prior to the modification. The major change in the instrument is the increase in OID of $92,000, and with a discount rate of 5% (equal to the interest rate) and a one-month extension, the present value is $165,975, which is over the 10% test. Therefore, the substantial modification is an extinguishment of the debt. Biolargo accounted for the $166,667 as a loss on extinguishment. This was recorded as a loss on debt extinguishment of debt on our Consolidated Statement of Operations and Comprehensive Loss.

On December 18, 2018, Vista Capital elected to convert $166,667 of the outstanding principal and interest of the Vista 2017 Note in conjunction with our agreement that the principal amount of the note had increased by $166,667 as a result of the OID provisions in the Triton Note (above), and we issued 666,668 shares of our common stock. As of December 31, 2018, the outstanding balance on the Vista Note totaled $550,000.

Vista Capital agreed to further extend the December 15, 2018 maturity date of this note (see Note 14, “Subsequent Events”).

Per the guidance of ASC 470-50, Debt Modifications and Extinguishments, modified terms are considered substantially different, if the present value of the cash flows after modification differ by at least 10% prior to the modification. With the increase in principal, the Vista Note met the 10% cash flow test and therefore the Company accounted for the transaction as an extinguishment of debt. The increased principal, and the warrant fair value treated as a fee for the extension, produced a $578,942 loss on extinguishment of the convertible debt. The new 5% Convertible Note is recorded at principal value with a 90-day maturity.

Two-Year Convertible Note, matures July 20, 2019

On July 20, 2017, the Company accepted $400,000 from one accredited investor, and issued a promissory note with a 10% original issue discount in the principal amount of $440,000 due in two years, which accrues interest at 12%. The note originally provided that interest was to be paid quarterly beginning October 1, 2017, in either cash, common stock, or an option to purchase common stock, in the holder’s discretion. On January 25, 2018, the interest provisions in the note were modified such that the 12% annual simple interest is due at maturity.

At maturity, the note automatically converts, at the holder’s option, into either BioLargo common shares at $0.42 per share, 2,000 shares of Clyra Medical common stock held by BioLargo, or any combination thereof. The fair value of the beneficial conversion feature resulted in a $171,000 discount recorded on our balance sheet as a discount on convertible notes payable, net of current portion. The discount will be amortized monthly as interest expense through July 20, 2019.

Lines of credit, mature September 1, 2019

On March 1, 2018, we received $390,000, and on September 1, 2018, we received $40,000, pursuant to a line of credit accruing interest at a rate of 18% per annum, for which we have pledged our inventory and accounts receivable as collateral. Interest is paid quarterly; the holder may choose to receive interest payments in (i) cash, (ii) our common stock, calculated based on the 20-day average closing price, or (iii) options to purchase our common stock, priced at the 20-day average closing price, the number of shares doubled, and expiring 10 years from the date of grant. The holder of the line of credit has the right to call due the outstanding principal amount on 30-days’ notice at any time after September 1, 2019.

Each creditor, for no additional consideration, received a warrant to purchase our common stock. The warrant allows for the purchase of the number of common shares equal to the investment amount (e.g., one warrant share for each dollar invested), at a price of $0.35 and expires March 1, 2023.

Convertible Notes, mature December 31, 2019 (Winter 2016 Unit Offering)

Of the $292,000 of promissory notes issued in our Winter 2016 Unit Offering, all but $75,000 were converted in May 2018 (see table above). This note, held by one investor, is due December 31, 2019. At maturity, we have the option to convert this note into common stock at $0.57 per share.

Convertible Notes, mature June 20, 2020 (Summer 2017 Unit Offering)

On May 24, 2017, we commenced a private securities offering (titled the “Summer 2017 Unit Offering”) which offered the sale of $1.5 million of “Units,” each Unit consisting of a convertible promissory note and stock purchase warrant. Concurrently, we issued Pricing Supplement No. 1 setting the initial unit/conversion price at $0.42 per share, and the initial warrant exercise price at $0.65 per share. The promissory notes issued to investors mature June 20, 2020, and bear interest at the rate of 12% per annum on the amount invested. Any interest due will be paid quarterly in arrears in cash or shares of common stock. If paid by the issuance of common stock, interest is paid at a conversion price equal to the average closing price of the Company’s common stock over the 20 trading days prior to the interest payment due date. The principal amount of the note may be paid by the issuance of shares of common stock, or cash, upon maturity at the Company’s election. Promissory notes may be converted at any time by the investor, at maturity by the Company, or by the Company prior to maturity, so long as the following conditions are met: (i) the Shares issued as payment are registered with the SEC; and (ii) the Company’s common stock closes for ten consecutive trading days at or above three times the Unit price.

In addition to the convertible promissory note, each investor received a warrant allowing for the purchase of the number of shares of BioLargo common stock equal to the investment amount divided by the unit/conversion price (e.g., one warrant share for each share of common stock which the investor is eligible to receive through conversion of the note). (See Note 7.) The warrants expire on June 20, 2022. The Company may “call” the warrants, requiring the investor to exercise their warrants within 30 days or forever lose the rights to do so, only if the following conditions have been met: (i) the underlying Shares are registered with the SEC and (ii) the Company’s common stock closes for 10 consecutive trading days at or above two times the exercise price.

We received a total of $604,000 of investments in this offering, from ten accredited investors. Of that amount, $524,000 were received in 2017, and $80,000 were received in 2018. The offering documents assured the investors that in the event a subsequent pricing supplement offered a lower conversion or exercise price, prior investors would be given those favorable terms. On December 29, 2017, we issued a pricing supplement lowering the unit price to $0.394. On February 12, 2018, we issued a third pricing supplement lowering the unit price to $0.30, and the warrant exercise price to $0.48 per share. As a result of these reductions, we notified each investor of the decrease in conversion price, and increased the number of warrant shares available to each investor.

In May 2018, investors holding notes in the principal amount of $478,000 elected to convert their notes to common stock (reflected in the table above). As a result of these conversions, we issued an aggregate 2,372,817 shares of our common stock (1,595,670 for principal, and 777,146 for interest). On November 11, 2018, a holder elected to convert a note in the principal amount of $100,000 and we issued 333,334 shares of common stock. As of December 31, 2018, one note in the principal amount of $25,000 remained outstanding on this offering.

Convertible Note, matures April 20, 2021 (Spring 2018 Unit Offering)

On March 26, 2018, we commenced a private securities offering (titled the “Spring 2018 Unit Offering”) which offered the sale of $1.5 million of “Units,” each Unit consisting of a convertible promissory note and stock purchase warrant. We set the initial unit/conversion price at $0.30 per share, and the initial warrant exercise price at $0.48 per share. The promissory notes issued to investors mature April 20, 2021, and incur interest at the rate of 12% per annum. Interest due will be paid quarterly in arrears in cash or shares of common stock, at our option. If paid by the issuance of common stock, interest is paid at a conversion price equal to the average closing price of the Company’s common stock over the 20 trading days prior to the interest payment due date. The principal amount of the note may be paid by the issuance of shares of common stock, or cash, upon maturity at the Company’s election. The notes may be converted at any time by the investor, at maturity by the Company, or by the Company prior to maturity, so long as the following conditions are met: (i) the shares issued as payment are registered with the SEC; and (ii) the Company’s common stock closes for ten consecutive trading days at or above three times the Unit price.

In addition to the convertible promissory note, each investor will receive a warrant allowing for the purchase of the number of shares of BioLargo common stock equal to the investment amount divided by the unit/conversion price (e.g., one warrant share for each share of common stock which the investor is eligible to receive through conversion of the note).

We received one investment in this offering, in March 2018, for $100,000, and issued a warrant to purchase 333,333 shares (see Note 7). This investment was received from an entity owned/controlled by a member of our board of directors. In light of the decreasing price of our common stock, in September 2018, we issued a pricing supplement reducing the unit price to $0.25 per share and reducing the warrant exercise price to $0.40 per share. As a result of the issuance of this pricing supplement, the unit and warrant price of the prior investor were changed to reflect these new prices. We received no further investments in this offering.

Convertible Notes, mature June 15, 2021 (OID Note)

On June 15, 2018, we received $75,000 and issued a convertible promissory note (titled the “OID Note”) in the principal amount of $82,500. On August 7, 2018, we received $25,000 and issued an OID Note in the principal amount of $32,500. These notes are convertible into shares of the Company’s common stock at a conversion price of $0.30 per share. The original issuance discount totaled $10,000, recorded as a discount on convertible notes payable on our balance sheet. The discount will be amortized and recorded to interest expense over the term of the note. The OID Notes mature June 15, 2021, and incurs interest at the rate of 15% per annum. Interest due will be paid quarterly in arrears in shares of common stock, paid at a conversion price equal to the average closing price of the Company’s common stock over the 20 trading days prior to the interest payment due date. The OID Notes are convertible by the investors at any time, and convertible by the Company (i) at maturity, (ii) in the event the Company’s stock price closes at two times the conversion price for 20 consecutive days, provided that either the shares underlying the convertible note are registered with the SEC, or more than six months has elapsed since the date of the investment.

Note payable, matures March 8, 2023 (or on demand)

On March 8, 2018, we received $50,000 and entered into a note payable. The note is due on upon demand from the noteholder, with sixty days’ notice. In the absence of the demand, the maturity date is March 8, 2023. In lieu of interest, we issued the note holder a warrant (see Note 7).

Note 6. Share-Based Compensation

Common Stock

On May 2, 2017, pursuant to an employment agreement with the Company’s president, Dennis P. Calvert (see Note 13), we issued Mr. Calvert 1.5 million shares of common stock, subject to a “lock-up agreement” whereby the shares remain unvested unless and until certain conditions are met (see Note 13). None of these conditions have been met. The Company will expense the fair value of the stock if and when it is probable that any of the conditions above are met.

During 2018, we issued 1,131,036 shares of our common stock at range of $0.24 - $0.43 per share in lieu of accrued and unpaid salary totaling $319,000. The shares issued to Mr. Calvert are unvested at the date of grant and subject to a lock-up agreement restricting vesting and sale until the earlier of (i) the consummation of a sale (in a single transaction or in a series of related transactions) of BioLargo by means of a sale of (a) a majority of the then outstanding common stock of BioLargo (whether by merger, consolidation, sale or transfer of common stock, reorganization, recapitalization or otherwise) or (b) all or substantially all of the assets of BioLargo; and (ii) the successful commercialization of BioLargo’s products or technologies as demonstrated by its receipt of at least $3,000,000 in cash, or the recognition of $3,000,000 in revenue, over a 12-month period from the sale of products and/or the license of technology; and (iii) the Company’s breach of the employment agreement between the Company and Calvert and resulting in Calvert’s termination.

During 2017, we issued 148,705 shares of our common stock at $0.39 per share in lieu of $58,000 of accrued and unpaid obligations to our officers.

Payment of Consultant Fees and Accrued Interest

During 2018, we issued 4,125,281 shares of our common stock at a range of $0.23 – $0.42 per share in lieu of $1,012,000 of accrued interest and accrued and unpaid obligations to consultants.

During 2017, we issued 2,272,116 shares of our common stock at a range of $0.39 – $0.70 per share in lieu of $1,078,000 of accrued interest and accrued and unpaid obligations to consultants.

All of these offerings and sales were made in reliance on the exemption from registration contained in Section 4(2) of the Securities Exchange Act and/or Regulation D promulgated thereunder as not involving a public offering of securities.

Stock Option Expense

During the years ended December 31, 2017 and 2018, we recorded an aggregate $1,103,000 and $1,335,000, respectively, in selling general and administrative expense related to the issuance of stock options. We issued options through our 2018 Equity Incentive Plan, our (now expired) 2007 Equity Incentive Plan, and outside of these plans.

2018 Equity Incentive Plan

On June 22, 2018, our stockholders adopted the BioLargo 2018 Equity Incentive Plan (“2018 Plan”) as a means of providing our directors, key employees and consultants additional incentive to provide services. Both stock options and stock grants may be made under this plan for a period of 10 years. It is set to expire on its terms on June 22, 2028. Our Board of Director’s Compensation Committee administers this plan. As plan administrator, the Compensation Committee has sole discretion to set the price of the options. The plan authorizes the following types of awards: (i) incentive and non-qualified stock options, (ii) restricted stock awards, (iii) stock bonus awards, (iv) stock appreciation rights, (v) restricted stock units, and (vi) performance awards. The total number of shares reserved and available for awards pursuant to this Plan as of the date of adoption of this 2018 Plan by the Board is 40 million shares. The number of shares available to be issued under the 2018 Plan increases automatically each January 1 ^st by the lesser of (a) 2 million shares, or (b) such number of shares determined by our Board.

Activity for our stock options under the 2018 Plan from June 22, 2018, inception date through the year ended December 31, 2018, is as follows:

2007 Equity Incentive Plan

On September 7, 2007, and as amended April 29, 2011, the BioLargo, Inc. 2007 Equity Incentive Plan (“2007 Plan”) was adopted as a means of providing our directors, key employees and consultants additional incentive to provide services. Both stock options and stock grants may be made under this plan for a period of 10 years, which expired on September 7, 2017. The Board’s Compensation Committee administers this plan. As plan administrator, the Compensation Committee has sole discretion to set the price of the options. As of September 2017, the Plan was closed to further stock option grants.

On June 19, 2017, the date of our annual stockholders’ meeting, we recorded the issuance of options to purchase an aggregate 40,000 shares of our common stock to the non-employee members of our Board of Directors, pursuant to the terms of the 2007 Plan which calls for an annual automatic issuance. The exercise price of $0.43 equals the price of our common stock on the grant date. The fair value of these options totaled $16,000 and was recorded as selling, general and administrative expense.

On February 10, 2017, we extended our engagement agreement with our Chief Financial Officer (and, see Note 14). The sole consideration for the one-year extension was the issuance of an option to purchase 300,000 shares of our common stock, at an exercise price of $0.69 per share which was equal to the closing price of our common stock on the date of grant. The option expires February 10, 2027, and vests over the term of the engagement with 125,000 shares having vested as of February 10, 2017, and the remaining shares to vest 25,000 shares monthly beginning March 1, 2017, and each month thereafter, so long as his agreement is in full force and effect. The fair value of the option totaled $207,000 and is recorded in selling, general and administrative expense. The option has fully vested.

Exercise of Stock Option

On April 30, 2017, our president, Dennis P. Calvert, delivered a notice of exercise of 3,866,630 shares pursuant to his stock option agreement dated April 30, 2007. The exercise price was $0.18 per share, and the Company issued to Mr. Calvert 2,501,937 shares, calculated by multiplying the difference between the market price of $0.51 and the exercise price of $0.18 with the number of shares exercised, and dividing that amount by the market price. No cash consideration was tendered with respect to the exercise. The remaining 3,866,629 shares available for purchase under the option agreement expired unexercised. Pursuant to a “lock-up agreement” dated April 30, 2017, Mr. Calvert agreed to restrict the sales of the shares received until the earlier of (i) the consummation of a sale (in a single transaction or in a series of related transactions) of the Company by means of a sale of (a) a majority of the then outstanding common stock (whether by merger, consolidation, sale or transfer of common stock, reorganization, recapitalization or otherwise) or (b) all or substantially all of its assets; and (ii) the successful commercialization of the Company’s products or technologies as demonstrated by its receipt of at least $3 million in cash, or the recognition of $3 million in revenue, over a 12-month period from the sale of products and/or the license of technology; and (iii) the Company’s breach of the employment agreement between the Company and Calvert dated May 2, 2017 and resulting in Calvert’s termination.

Warrants issued concurrently with promissory notes

In conjunction with a $225,000 investment and note issued in the principal amount of $300,000 to Triton (see Note 5, “ Convertible note payable, matures January 11, 2019 (Triton) ”), we issued a stock purchase warrant to Triton allowing Triton to purchase up to an aggregate 1,000,000 shares of our common stock for $0.25 per share, expiring October 12, 2023. The relative fair value of this warrant totaled $225,000 and was recorded as a discount on our convertible notes and will be amortized to interest expense through the January 11, 2019 maturity of the note.

We may “call” the warrant if the closing price of our common stock equals or exceeds $0.50 for 10 consecutive trading days and the shares underlying the warrant are subject to an effective registration statement with the Securities and Exchange Commission. If we call the warrant, Triton would have 30 days to exercise its rights to purchase shares under the warrant or forever forfeit such rights. If the shares underlying the warrant are not registered, Triton may exercise the warrant pursuant to a formula (a “cashless” exercise).

On September 19, 2018, pursuant to the terms of the convertible notes payable due January 5, 2019 (see Note 5, “ Convertible Note s , mature January 5, 2019 ”), we issued warrants to purchase up to an aggregate 1,387,500 shares of our common stock at an exercise price of $0.25 per share. These warrants expire September 19, 2023. We may “call” the warrants if the closing price of our common stock equals or exceeds $2.50 for 10 consecutive trading days and the shares underlying the warrant are subject to an effective registration statement with the Securities and Exchange Commission. If we call the warrants, each investor would have 30 days to exercise its rights to purchase shares under the warrant or forever forfeit such rights.

The relative fair value of these warrants resulted in $217,000 recorded as a discount on our consolidated balance sheet in the period issued. The discount will amortize to interest expense through the maturity date of the convertible notes.

On September 12, 2018, Vista Capital agreed to extend the maturity date of its note dated December 18, 2017 (See Note 5, “ Convertible Note, matures April 15, 2019 (Vista Capital) ”). Pursuant to our amendment of the Note extending the maturity date, we issued Vista Capital a warrant to purchase 1,812,000 shares of our common stock at $0.25 per share. This warrant expires September 12, 2023. The fair value of this warrant resulted in $488,000 of loss on extinguishment of debt in 2018.

On March 8, 2018, we issued a warrant to purchase up to 150,000 shares of our common stock (subject to vesting) at an exercise price of $0.35 per share to the holder of a note of the same date in the principal amount of $50,000 (see Note 5, “ Note payable, matures March 8, 202 3 (or on demand) ”). The warrant expires February 28, 2023. At the end of each month, 6,250 shares vest as long as the note payable is outstanding. At December 31, 2018, 56,250 shares had vested. The fair value the warrant totaled $7,000 and was recorded as interest expense.

Reduction of Warrant Exercise Price

In May 2018, certain holders of outstanding warrants to purchase common stock received in prior unit offerings paid us cash in exchange for a reduction of the exercise price in their warrant(s). In the aggregate, we received $149,000 from holders of 37 warrants which allow for the purchase of an aggregate 4,326,358 shares of our common stock. Exercise prices of these warrants were reduced to $0.30. Management determined that the appropriate accounting treatment for the reduction in the exercise price of the warrants was a capital transaction rather than a contract modification treatment analogous to changes in stock option contracts. As such, the fair value was equal to the cash received totaling $149,000.

Warrants Issued Concurrently with Spring 2018 Unit Offering

During 2018, pursuant to the terms of our Spring 2018 Unit Offering (see Note 5, “ Convertible Note, matures April 20, 2021 (Spring 2018 Unit Offering) ”), we issued a warrant to purchase up to 333,333 shares of our common stock at an exercise price of $0.48 per share to the investor in the Spring 2018 Offering. The warrant expires April 20, 2023. The relative fair value of the warrant resulted in $49,000 recorded as a discount on our convertible notes on our consolidated balance sheet in the period issued. Subsequent to the issuance of this warrant, the unit price for this offering was reduced, and as a result, the Company was obligated to increase the number of shares available for purchase under the warrant from 333,333 to 400,000. The exercise price of the warrant was concurrently reduced. The fair value of this warrant resulted in $17,000 recorded as interest expense during the year ended December 31, 2018.

The Company may “call” the warrants issued in the Spring 2018 Offering, requiring the holder to exercise their warrant within 30 days or forever lose the rights to do so, if the following conditions have been met: (i) the shares of common stock underlying the warrants are registered with the SEC and (ii) the Company’s common stock closes for 10 consecutive trading days at or above two times the exercise price.

Warrants Issued Concurrently with Line of Credit Offering

During 2018, pursuant to the terms of our Line of Credit (see Note 5, “ Line of Credit, matures September 1, 2019 ”), we issued warrants to purchase up to an aggregate of 430,000 shares of our common stock. Of this amount 390,000 shares of our common stock are at an exercise price of $0.35 per share and 40,000 shares are at an exercise price of $0.25 per share. These warrants expire March 1, 2023. The relative fair value of these warrants resulted in $98,000 recorded as a discount on our convertible notes payable and line of credit on our consolidated balance sheet in the period issued.

The Company may “call” these warrants, requiring the holder to exercise their warrants within 30 days or forever lose the rights to do so, if the following conditions have been met: (i) the shares of common stock underlying the warrants are registered with the SEC and (ii) the Company’s common stock closes for 10 consecutive trading days at or above two times the exercise price.

Warrants Issued to Summer 2017 Unit Offering Investors

Pursuant to the terms of our Summer 2017 Unit Offering (see Note 5), we issued warrants to purchase an aggregate 1,246,906 shares of our common stock, at an exercise price of $0.65 per share. These warrants expire June 20, 2022. The relative fair value of these warrants resulted in $524,000 recorded as a long-term discount on our convertible notes.

The offering documents assured the investors that in the event a subsequent pricing supplement offered a lower conversion or exercise price, prior investors would be given those favorable terms. On December 29, 2017, we issued a second pricing supplement, lowering the conversion price to $0.394. As a result of this reduction, we notified each investor of the decrease in conversion price, and increased the number of warrant shares available to each investor. In the aggregate, the number of warrant shares increased by 82,283, such that the warrants, in the aggregate, allow for the purchase of 1,329,189 shares. The relative fair value of these additional warrants resulted in $32,000 recorded as a long-term discount on our convertible notes.

On February 12, 2018, we issued a third pricing supplement, lowering the unit price to $0.30. As a result of this reduction, the number of shares purchasable pursuant to warrants issued to prior investors increased by an aggregate 416,478 shares. Additionally, during the three months ended March 31, 2018, we accepted two final investments in the aggregate amount of $80,000, pursuant to the third pricing supplement, and issued these investors warrants to purchase an aggregate 266,667 shares. The relative fair value of these warrants, including the increase in purchasable shares, resulted in $103,000 recorded as a discount on our consolidated balance sheet in the period issued.

Warrants Issued to One-Year Noteholders

In conjunction with three separate investments of one-year convertible notes, we issued three sets of warrants to purchase an aggregate 400,000 shares to two investors. These warrants were issued July 8, 2016 (400,000 shares at $0.65 exercise price), December 30, 2016 (400,000 shares at $0.75 exercise price), and July 18, 2017 (400,000 shares at $0.65 exercise price). The fair value of these warrants resulted in a $280,000 discount recorded on our balance sheet as of December 31, 2017 as a discount on convertible note payable and will be amortized monthly as interest expense in 2017.

Each of these warrants contained provisions that required a reduction to the exercise price and increase to the number of warrant shares in the event that we sold our common stock at a lower price than the exercise price (subject to some exceptions). During the year ended December 31, 2017, we adjusted downward the warrant exercise price three times to $0.394, resulting in a fair value totaling $344,000, recorded as a deemed dividend in our statement of stockholders’ equity. During the year ended December 31, 2018, we adjusted downward the warrant exercise price to $0.25, resulting in a fair value totaling $297,000, recorded as a deemed dividend in our statement of stockholders’ equity.

Exercise of Warrants

During the year ended December 31, 2017, we issued 510,000 shares of our common stock from the exercise of outstanding stock purchase warrants and in exchange we received proceeds totaling $153,000.

Fair Value – Interest Expense

To determine interest expense related to our outstanding warrants issued in conjunction with debt offerings, the fair value of each award grant is estimated on the date of grant using the Black-Scholes option pricing model and the relative fair values are amortized over the life of the warrant. For the determination of expense of warrants issued for services, extinguishment of debt and settlement management also uses the option-pricing model. The principal assumptions we used in applying this model were as follows:

	2017			2018
Risk free interest rate	1.71	–	2.10%	2.54	–	3.00%
Expected volatility	221	–	297%	105	–	127%
Expected dividend yield		—			—
Forfeiture rate		—			—
Expected life in years	3	–	5	3	–	5

The risk-free interest rate is based on U.S. Treasury yields in effect at the time of grant. Expected volatilities are based on historical volatility of our common stock. The expected life in years is based on the contract term of the warrant.

Note 8. Accounts Payable and Accrued Expenses

Accounts payable and accrued expenses included the following (in thousands):

	December		December
		31, 2017		31, 2018
Accounts payable and accrued expense	$	88	$	302

Note 9. Provision for Income Taxes

Given our historical losses from operations, income taxes have been limited to the minimum franchise tax assessed by the State of California. Our subsidiary BLEST is a Tennessee limited liability company and as such, is not consolidated in our corporate tax return. As a pass through entity, it does not pay federal taxes. However, the state of Tennessee charges franchise and excise taxes for limited liability companies, and thus BLEST will incur a nominal franchise tax and will not pay an excise tax unless and until it is profitable.

At December 31, 2018, we had federal and California tax net operating loss carry-forwards (“NOLs”) of approximately $58.5 million. Due to changes in our ownership through common stock issuances throughout the year, the utilization of NOLs may be subject to annual limitations and discounts under provisions of the Internal Revenue Code. We have not conducted a complete analysis to determine the extent of these limitations or any future limitation. Such limitations could result in the permanent loss of a significant portion of the NOLs. Given the impact of the Tax Cuts and Jobs Act (“TCJA”) signed into law on December 22, 2017, the future expected corporate tax rate was reduced to 21%. Accordingly, the Company measured its deferred tax asset for these NOLs and estimated a deferred tax asset of approximately $11.1 million for federal, and $4.6 million for California. Under the TCJA, NOLs may be carried forward indefinitely; however, the NOLs are limited to the lesser of (1) the aggregate of the NOL carryovers to such year, plus the NOL carry-backs to such year, or (2) 80% of taxable income (determined without regard to the deduction) (Sec. 172(a)). Generally, NOLs can no longer be carried back but are allowed to be carried forward indefinitely (Sec. 172(b)(1)(A)). Nevertheless, for California purposes, the additional taxable income limitations on NOL carryforwards as well as the indefinite time to use the NOLs have not been adopted. Therefore for California, NOLs expire after 20 years. As such, ours will begin to expire in for the tax period ending December 31, 2021. Realization of our deferred tax assets, which relate to operating loss carry-forwards and timing differences, is dependent on future earnings. The timing and amount of future earnings are uncertain and therefore we have established a 100% valuation allowance.

Note 10. Noncontrolling Interest – Clyra Medical

We consolidate the operations of our partially owned subsidiary Clyra Medical (see Note 2, “Principles of Consolidation”).

On March 31, 2017, Clyra Medical received $250,000 from an existing Clyra Medical shareholder (Sanatio Capital LLC), and issued a line of credit note accruing interest at a rate of 10% per annum and a 5% original issue discount.

In April 2017, BioLargo purchased 500 shares of Clyra Medical common stock from a former member of Clyra Medical’s management for $40,000.

In August 2017, Clyra Medical commenced a private securities offering of its common shares at a price of $160 per share, and accepted $1 million in subscriptions from two investors. Of that amount, BioLargo invested $250,000 and was issued 1,562.5 shares. Concurrently, Sanatio Capital converted the outstanding amount due on its line of credit at $160 per share into 1,690 Clyra Medical common shares.

On September 26, 2018, Clyra Medical entered into a transaction with Scion Solutions, LLC, for the purchase of its intellectual property, including its SkinDisc (see Note 3). Shortly thereafter, it commenced a private securities offering to raise the funds necessary to meet the closing obligations in the Scion transaction. As of December 31, 2018, it had raised $1,005,000 at a price of $200 per share. On December 17, 2018, it announced it had met the closing obligations for the Scion transaction (see Note 3).

As of December 31, 2018, Clyra Medical had the following common and preferred shares outstanding:

Shareholder	Shares		Percent
BioLargo, Inc.		28,053		42.3	%
Sanatio Capital ⁽¹⁾		11,520		17.4	%
Scion Solutions ⁽²⁾		15,500		23.4	%
Other		11,222		16.9	%
Total		66,295

Notes:

(1) Includes 9,830 Series A Preferred shares (see below), and 1,690 common shares.

(2) Does not include an additional 15,500 shares held in escrow subject to performance metrics (see Note 3).

F-29

Table of Contents

Sanatio Capital purchased Series A Preferred shares in 2015. Sanatio Capital is owned by Jack B. Strommen, who subsequently joined BioLargo’s board of directors. Preferred Shares accrue an annual dividend of 8% for a period of five years. Although the dividends began to accrue immediately, Clyra Medical has no obligation to declare a dividend until a product of the company has received a premarket approval by the United States Federal Drug Administration (“FDA”), or for which a premarket notification pursuant to form 510(k) has been submitted and for which the FDA has given written clearance to market the product in the United States (either, “FDA Approval”). After FDA Approval, annually on December 20, and unless prohibited by California law governing distributions to shareholders, Clyra Medical is required to declare and pay any accruing dividends to holders of Preferred Shares then accrued but unpaid. As the declaration and payment of such dividends is contingent on an uncertain future event, no liability has been recorded for the dividends. The accumulated and undeclared dividend balance as of December 31, 2018 is $185,000.

Holders of Preferred Shares are entitled to preferential payments in the event of a liquidation, dissolution or winding up of the company, in an amount equal to any accrued and unpaid dividends. After such preference, any remaining assets are distributed pro-rata between holders of Clyra Medical common stock and Preferred Shares as if the Preferred Shares had converted to Clyra Medical common stock. Holders of Preferred Shares may convert the shares to Clyra Medical common stock initially on a one-to-one basis. The conversion formula is subject to change in the event Clyra Medical sells stock at a lower price than the price paid by Sanatio.

Preferred shares may be converted to common shares on a one-to-one basis, and have voting rights equal to common shares on a one-to-one basis.

Note 11. Biolargo Engineering, Science and Technologies, LLC

In September 2017, we commenced a full-service environmental engineering firm and formed a Tennessee entity named BioLargo Engineering, Science & Technologies, LLC (“BLEST”). In conjunction with the start of this subsidiary, we entered into a three-year office lease in the Knoxville, Tennessee area, and entered into employment agreements with seven scientists and engineers. (See Note 12 “Business Segment Information”.) The company was capitalized with two classes of membership units: Class A, 100% owned by Biolargo, and Class B, held by management of BLEST, and which initially have no “profit interest,” as that term is defined in Tennessee law. However, over the succeeding five years, the Class B members can earn up to a 30% profit interest. They also have been granted options to purchase up to an aggregate 2 million shares of BioLargo, Inc. common stock. The profit interest and option shares are subject to a five year vesting schedule tied to the performance of the subsidiary, including gross revenue targets that increase over time, obtaining positive cash flow by March 31, 2018 (which was not met), collecting 90% of its account receivables, obtaining a profit of 10% in its first year (and increasing in subsequent years), making progress in the scale-up and commercialization of our AOS system, and using BioLargo research scientists (such as our Canadian team) for billable work on client projects. These criteria are to be evaluated annually by BLEST’s compensation committee (which includes BioLargo’s president, CFO, and BLEST’s president), beginning September 2018. The details of these transactions were reported on a Form 8-K filed with the SEC on September 8, 2017. Given the significant performance criteria, the Class B units and the stock options will only be recognized in compensation expense if or when the criteria are satisfied.

The Compensation Committee met on September 26, 2018 and reviewed the operating performance of the engineering subsidiary and determined that the performance metrics were not met and as a result, did not award any Class B units or stock options. The Committee decided to roll forward one additional year to the time allowed for the performance metrics to be met and for the Class B units and stock options to be awarded.

Note 12. Business Segment Information

BioLargo currently has four operating business segments, plus its corporate entity which is responsible for general corporate operations, including administrative functions, finance, human resources, marketing, legal, etc. The four operational business segments are:

Odor-No-More -- which is selling odor and volatile organic control products and services (located in Westminster, California);

BLEST -- which provides professional engineering services on a time and materials basis for outside clients and supports our internal operations as needed (located in Oak Ridge, Tennessee);

BioLargo Water -- which historically focused entirely on R&D, and has now shifted its focus to commercializing the AOS technology (located in Edmonton, Alberta Canada); and

Clyra Medical -- which is engaged in developing medical products and preparing launch into commercial activity with approval of its FDA 510 (K) application in process (located in Florida).

Historically, none of our operating business units operated at a profit and therefore each required additional cash to meet its monthly expenses. The additional sources of the cash to fund the shortfall from operations of Odor-No-More, BLEST and BioLargo Water have been provided by BioLargo’s sales of debt or equity, research grants, and tax credits. Clyra Medical has been funded by third party investors who invest directly in Clyra Medical in exchange for equity ownership in that entity. For example, during the year ended December 31, 2018, we provided Odor-No-More with approximately $417,000 in cash to supplement its operations. As this subsidiary’s sales have increased (from approximately $500,000 in calendar year 2017 to over $1 million in calendar year 2018), and its gross margins have improved, it has generated more cash for its operations and relied less on corporate to supplement its cash to pay its bills.

Note 13. Commitments and Contingencies

Calvert Employment Agreement

On May 2, 2017, the Company entered into an employment agreement with its President and Chief Executive Officer Dennis P. Calvert (the “Calvert Employment Agreement”), replacing in its entirety the previous employment agreement with Mr. Calvert dated April 30, 2007.

The Calvert Employment Agreement provides that Mr. Calvert will continue to serve as our President and Chief Executive Officer and receive base compensation equal to his current rate of pay of $289,000 annually. During the year ended December 31, 2018, Mr. Calvert took only one-half ($147,000) in cash – the balance was paid in shares of our common stock with significant restrictions on resale (see Note 6). In addition to this base compensation, the agreement provides that he is eligible to participate in incentive plans, stock option plans, and similar arrangements as determined by the Company’s Board of Directors, health insurance premium payments for himself and his immediate family, a car allowance, paid vacation of four weeks per year, and bonuses in such amount as the Compensation Committee may determine from time to time.

Pursuant to the Calvert Employment Agreement, we granted Mr. Calvert a non-qualified stock option (the “Option”) to purchase 3,731,322 shares of our common stock, exercisable at $0.45 per share, which represented the market price of the Company’s common stock as of the date of the agreement, exercisable for ten years from the date of grant and vesting in equal increments over five years (see Note 7). The Option provides that any portion of the Option which has not yet vested shall be immediately vested in the event of, and prior to, a change of control, as defined in the Calvert Employment Agreement. The Calvert Employment Agreement also provides for a grant of 1,500,000 shares of common stock, subject to the execution of a “lock-up agreement” whereby the shares remain unvested unless and until the earlier of (i) a sale of the Company, (ii) the successful commercialization of the Company’s products or technologies as demonstrated by its receipt of at least $3 million in cash, or the recognition of $3 million in revenue, over a 12-month period from the sale of products and/or the license of technology, and (iii) the Company’s breach of the employment agreement resulting in his termination. The Option contains the other terms standard in option agreements issued by the Company, including provisions for a cashless exercise.

The Calvert Employment Agreement has a term of five years, unless earlier terminated in accordance with its terms. The Calvert Employment Agreement provides that Mr. Calvert’s employment may be terminated by the Company due to his death or disability, for cause, or upon a merger, acquisition, bankruptcy or dissolution of the Company. “Disability” as used in the Calvert Employment Agreement means physical or mental incapacity or illness rendering Mr. Calvert unable to perform his duties on a long-term basis (i) as evidenced by his failure or inability to perform his duties for a total of 120 days in any 360-day period, or (ii) as determined by an independent and licensed physician whom Company selects, or (iii) as determined without recourse by the Company’s disability insurance carrier. “Cause” means that Mr. Calvert has (i) engaged in willful misconduct in connection with the Company’s business; or (ii) been convicted of, or plead guilty or nolo contendre in connection with, fraud or any crime that constitutes a felony or that involves moral turpitude or theft. If Mr. Calvert’s employment is terminated due to merger or acquisition, then he will be eligible to receive the greater of (i) one year’s compensation plus an additional one-half year for each year of service since the effective date of the employment agreement or (ii) one year’s compensation plus an additional one-half year for each year remaining in the term of the agreement. Otherwise, he is only entitled to receive compensation due through the date of termination.

Clyra Medical Consulting Agreement

Our partially owned subsidiary Clyra Medical (see Note 10) entered into a consulting agreement with Beach House Consulting, LLC, through which Jack B. Strommen will be providing consulting services to Clyra Medical related to its sales and marketing activities once it has received FDA Approval (as defined in Note 10 and the associated agreement) on a product, at which point the agreement provides that Mr. Strommen is to receive $23,000 per month for a period of four years. This agreement has not started, and the total cash obligation related to the agreement would be $1.1 million.

Note 14. Subsequent Events.

Management has evaluated subsequent events through the date of the filing of this Annual Report and management noted the following for disclosure.

Debt obligations – Extension of notes due January 5, 2019

By letter dated January 3, 2019, we notified the holders of two promissory notes in the aggregate principal amount of $400,000 (the first held by Vernal Bay Investments, LLC (“Vernal”) in the original principal amount of $280,000, and the second held by Chappy Bean, LLC (“Chappy Bean”) in the original principal amount of $120,000) of our election to extend by 60 days, to March 6, 2019, the maturity dates of the notes (see Note 5). As provided in the notes, our election to extend increased the principal amount of each note by 10%, such that the aggregate principal balance of the two notes increased to $440,000 as of January 3, 2019.

On March 5, 2019, we executed amendments to these two notes that extended the maturity dates initially to June 6, 2019, and provide that we may further extend the maturity dates to September 6, 2019 by giving written notice of such extension and increasing the principal due on the notes at that time by 10%. As consideration of the extension of the maturity dates reflected in the March 5, 2019 amendments, we (i) increased the annual percentage rate of interest from 12% to 18%, effective as of March 7, 2019, and (ii) lowered the exercise price, and increased the number of shares available, on warrants that had been previously issued to the two investors (at the time of their original investment). With respect to the warrants, Vernal Bay had been issued a warrant to purchase 1,387,500 shares at $0.25 per share, expiring September 19, 2023. We agreed to lower the exercise price to $0.20 per share, and proportionately increase the number of shares in the warrant to 1,734,375. By doing so, the maximum investment amount under the warrant of $346,875 remained the same. Chappy Bean’s warrant to purchase 600,000 shares was similarly modified, such that it now allows for the purchase of 750,000 shares at $0.20 per share.

Debt Obligations –Convertible Note, matures April 15, 2019 (Vista Capital)

On January 7, 2019, we and Vista Capital agreed to amend the convertible promissory note originally issued December 14, 2017 (“Vista 2017 Note”; see Note 5) and extend its maturity date to April 15, 2019. The principal amount of the note was increased to $605,100. The note will continue to earn interest at the rate of five percent per annum. The amendment re-defined the conversion price to equal 80% of the lowest closing bid price of the Company’s common stock during the 25 consecutive trading days immediately preceding the conversion date. The amendment also reduced the prepayment penalty from 20% to 15%, such that a prepayment requires the payment of an additional 15% of the then outstanding balance, and reduced the penalty for a default from 30% to 25% of the outstanding balance.

Per the guidance of ASC 470-50, “Debt Modifications and Extinguishments,” modified terms are considered substantially different, if the present value of the cash flows after modification differ by at least 10% prior to the modification. With the increase in principal, the Vista 2017 Note met the 10% cash flow test and therefore the Company accounted for the transaction as an extinguishment of debt. The increased principal, and the warrant fair value treated as a fee for the extension, produced a $746,000 loss on extinguishment of the convertible debt. The new 5% Convertible Note is recorded at principal value with a 90-day maturity.

Subsequent to the January 7, 2019 amendment, Vista Capital has chosen to convert $225,000 of the Vista 2017 Note (credited to interest and then principal), and received an aggregate 1,679,248 shares of our common stock. We and Vista Capital have agreed to further extend the maturity date from April 15, 2019 to July 15, 2019, and as consideration have increased the principal balance of the note by 10%. Accounting for these conversions and the extension, the principal amount due on the note is $420,452

Concurrently with the January 7, 2019 extension of the Vista 2017 Note, Vista Capital invested an additional $300,000 and we issued a convertible promissory note (the “Vista 2019 Note”) in the principal amount of $330,000, maturing nine months from the date of issuance (October 7, 2019). The Vista 2019 Note earned a one-time interest charge of 12%. The Vista 2019 Note allows Vista Capital to convert the note to our common stock at any time at a price equal to 65% of the lowest closing bid price of the Company’s common stock during the 25 consecutive trading days immediately preceding the conversion date. The Vista 2019 Note contains standard provisions of default, and precludes the issuance of shares to the extent that Vista Capital would beneficially own more than 4.99% of our common stock. We may pre-pay the Vista 2019 Note within 90 days of the issuance date by giving 10 business day notice of the intent to pre-pay, and then tendering 120% of the outstanding balance of the note. Vista Capital has the option to convert the note to common stock during the 10-day period. The Vista 2019 Note also includes a term that allows Vista Capital to adopt any term of a future financing more favorable than what is provided in the note. For example, these provisions could include a more favorable interest rate, conversion price, or original issue discount. The Vista 2019 Note also requires that we include the shares underlying conversion of the note on the next registration statement we file with the SEC (but not the registration statement filed November 6, 2018).

With respect to the above transactions with Vista Capital, Lincoln Park Capital Fund, LLC agreed to waive the provisions of the Purchase Agreement dated August 25, 2017, prohibiting variable rate transactions. As consideration for this waiver, we issued to Lincoln Park a warrant to purchase 250,000 shares of our common stock at $0.25 per share, expiring five years from the date of grant. In the event the shares underlying the warrant are not registered, the warrant allows the holder to do a “cashless” exercise.

Debt Obligations – Payment of Note due January 11, 2019 (Triton)

On January 9, 2019, we tendered payment of the outstanding principal amount and interest due on the promissory note issued to Triton Funds, LP dated October 12, 2018 (see Notes 5 and 7). Other than the outstanding warrants, we have no ongoing business dealings with Triton.

Debt Obligations – Note due November 5, 2019 (Tangiers Global)

On January 31, 2019, we issued a 12% Convertible Promissory Note to Tangiers Global, LLC (“Tangiers”) in the aggregate principal amount of up to $495,000 (the “Tangiers Note”). The initial principal amount of the Tangiers Note is $330,000, for which Tangiers paid a purchase price of $300,000 on February 5, 2019, representing a 10% original issue discount, due November 5, 2019. As originally contemplated, we received an additional $150,000 from Tangiers pursuant to an amendment to the note dated March 7, 2019, increasing the principal amount due under the note to $495,000.

F-34

Table of Contents

The Tangiers Note is convertible at the option of Tangiers at a conversion price equal to 75% of the lowest closing bid price of the Company’s common stock during the 25 consecutive trading days prior to the conversion date. We may prepay the Tangiers Note up to 180 days after the effective date. If a prepayment is made within 90 days, we must pay a prepayment penalty of 25%; from 91 to 180 days, we must pay a prepayment penalty of 30%. We may pay such prepayment penalties, if we so choose, by issuing common stock at the conversion price. If such shares are not eligible for removal of restrictions pursuant to a registration statement or Rule 144 within 10 trading days following the six-month anniversary of the effective date, Tangiers may rescind the stock issuance and force the Company to pay the prepayment penalty in cash. Upon the occurrence of an event of default, as such term is defined under the Tangiers Note, additional interest will accrue from the date of the event of default at a rate equal to the lower of 22% per annum or the highest rate permitted by law, and an additional 25% shall be added to the principal amount of the note.

In connection with the Tangiers Note, the Company caused its transfer agent to reserve 3,000,000 shares of the Company’s common stock, in the event that the Tangiers Note is converted.

With respect to the above transaction with Tangiers, Lincoln Park consented to waive the provisions of the Purchase Agreement dated August 25, 2017 prohibiting variable rate transactions. As consideration for the consent, we agreed to issue Lincoln Park a stock purchase warrant allowing for the purchase of 50,000 shares of our common stock at $0.25 per share, expiring five years from the date of grant. In the event the shares underlying the warrant are not registered, the warrant allows the holder to do a “cashless” exercise.

Chief Financial Officer Contract Extension

On January 16, 2019, we agreed to extend the engagement agreement dated February 1, 2008 (the “Engagement Agreement”, which had been previously extended multiple times) with our Chief Financial Officer, Charles K. Dargan, II. The Engagement Extension Agreement dated as of January 16, 2019 (the “Engagement Extension Agreement”) provides for an additional term to expire September 30, 2019 (the “Extended Term”), and is retroactively effective to the termination of the prior extension on September 30, 2018. Mr. Dargan has been serving as the Company’s Chief Financial Officer since such termination pursuant to the terms of the December 31, 2017 extension.

For the Extended Term, Mr. Dargan was issued an option (“Option”) to purchase 300,000 shares of the Company’s common stock, at a strike price equal to the closing price of the Company’s common stock on January 16, 2019 of $0.223, to expire January 16, 2029, and to vest over the term of the engagement with 75,000 shares having vested as of December 31, 2018, and the remaining shares to vest 25,000 shares monthly beginning January 31, 2019, and each month thereafter, so long as the Engagement Agreement is in full force and effect. The Option was issued pursuant to the Company’s 2018 Equity Incentive Plan.

The issuance of the Option is Mr. Dargan’s sole source of compensation for the Extended Term. As was the case in all prior terms of his engagement, there is no cash component of his compensation for this term. Mr. Dargan is eligible to be reimbursed for business expenses he incurs in connection with the performance of his services as the Company’s Chief Financial Officer (although he has made no such requests for reimbursement in the past). All other provisions of the Engagement Agreement not expressly amended pursuant to the Engagement Extension Agreement remain the same, including provisions regarding indemnification and arbitration of disputes.
