SUMMARY

This summary contains basic information about us and this offering. Because it is a summary, it does not contain all of the information that you should consider before investing. Before you decide to invest in our common shares, you should read this entire prospectus carefully, including the section entitled “Risk Factors,” and any documents incorporated by reference.

Our Business

We believe that the surest path to a better future is through technological advancement and that the new frontier of technology lies at the interface of computation, engineering and biology. Our mission is to improve health with technologies that transform the way that antibody-based therapies are discovered. We aim to become the centralized operating system for next generation antibody discovery.

Our full-stack, artificial intelligence-, or AI, powered antibody discovery platform searches and analyzes the database of natural immune systems to find antibodies that can be developed as drugs. We believe our technology increases the speed and the probability of success of therapeutic antibody discovery, including enabling discovery against targets that may otherwise be intractable. We forge partnerships with drug developers of all sizes, from large cap pharmaceutical to small biotechnology companies. We empower them to move quickly, reduce cost and tackle the toughest problems in drug development. As of December 31, 2021, we had 156 discovery programs that are either completed, in progress or under contract with 36 partners. As a recent example, in a collaboration with Eli Lilly and Company, or Lilly, we applied our technology stack to co-develop two antibody therapies to treat and prevent cases of mild-to-moderate COVID-19. At the start of the pandemic, when bringing a treatment to patients quickly was the priority, we discovered bamlanivimab from a single blood sample obtained from a convalescent patient, and with our partners, advanced into clinical testing 90 days after initiation of the program. It was the first monoclonal antibody therapy to reach clinical testing and the first to receive Emergency Use Authorization, or EUA, from the U.S. Food and Drug Administration, or FDA, for the treatment of COVID-19 in high-risk patients. Since receiving authorization in November 2020, bamlanivimab alone and together with other antibodies has been used to treat approximately a million patients, potentially preventing tens of thousands of hospitalizations and deaths. Knowing that additional antibodies would be needed to combat emerging variants, we deployed our platform to identify bebtelovimab (also known as LY-CoV1404), a highly potent antibody that neutralizes Omicron and all currently known variants of concern (VOC). Lilly advanced bebtelovimab into clinical testing in May 2021 and received an EUA from the FDA in February 2022. Lilly progressed into these clinical trials at a greatly accelerated pace as a result of the Coronavirus Treatment Acceleration Program, which is a special emergency program for possible coronavirus therapies created by the FDA in 2020 to expedite the development of potentially safe and effective life-saving treatments to combat the COVID-19 pandemic. With respect to other or future product candidates, there is no assurance that any of our partners or collaborators will be able to advance a product candidate into clinical development on this timeframe again in the future. We initiated our partnering program in 2015 and have only had this one program result in clinical milestone payments to us to date, and we have not yet had a program receive marketing approval.

UNAUDITED PRO FORMA CONDENSED COMBINED FINANCIAL INFORMATION

In November 2020, we entered into the merger agreement with Trianni, under which, at the effective time, our wholly owned entity, or Merger Sub, merged with and into Trianni, with Trianni surviving as our wholly owned subsidiary.

Notes to Unaudited Pro Forma Condensed Combined Financial Statements

(in thousands of U.S. dollars, except share and per share data)

Note 1—Description of the Transaction

In November 2020, we entered into the merger agreement with Trianni, under which at the closing, Merger Sub, merged with and into Trianni, with Trianni surviving as our wholly owned subsidiary.

Pursuant to the merger agreement, each share of Trianni convertible preferred stock was converted into one share of common stock of Trianni and each share of Trianni common stock (other than excluded shares and dissenting shares) was converted automatically into the right to receive cash in the amount equal to the purchase price divided by the total number of common stock of Trianni issued and outstanding. Further, each unexercised outstanding option to purchase shares of Trianni common stock whether vested or unvested, was cancelled and extinguished.

TABLE OF CONTENTS

To fund the merger, we issued the Convertible Notes in the aggregate principal amount of $90.0 million on October 30, 2020. The Convertible Notes mature five years from the date of issuance and bear no interest for the first twelve months and bear five percent (5%) interest per annum thereafter. Interest is payable annually starting twenty-four months from the date of issuance until maturity.

Upon the closing of certain qualified financings under the Convertible Notes, each a Qualified Financing, the principal amount of the Convertible Notes can be converted at the option of the note holder into our common shares of at a conversion price as specified in the convertible note agreement. The Convertible Notes are also convertible at the option of the holders on the interest commencement date, which is 12 months after the issuance date. The number of common shares to be issued will be equal to 800,000 common shares (for certain specified investors) plus the number of common shares determined by dividing (i) the aggregate of the outstanding principal of the Convertible Note by (ii) our pre-money valuation of as defined in the agreement divided by the aggregate number of our common shares outstanding at the time of conversion. At issuance, we determined that no value should be assigned to the embedded derivatives and that there was no beneficial conversion feature.

Immediately prior to the completion of our IPO, the Convertible Notes were converted into 6,093,524 common shares of the Company in accordance with the terms of the convertible note agreement.

ASU No. 2016-02, Leases (Topic 842) , which is referred to as ASC 842—Trianni has not yet adopted ASC 842, and we adopted it with an effective date of January 1, 2019. For purposes of the unaudited condensed combined pro forma statements of operations for the year ended December 31, 2020, Trianni only had one operating lease as classified under ASC 842. Any resulting change would be immaterial and thus, for the purposes of the pro forma financial information, Trianni has not adjusted AbCellera’s adoption of ASC 842 to January 1, 2020.

•

ASU No. 2016-13, Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, which is referred to as ASC 326. Trianni’s historical financial statements used to derive the pro forma financial information do not reflect the adoption of ASC 326. For the purposes of the pro forma financial information, we have not adjusted Trianni’s adoption of ASC 326 to January 1, 2020 as the estimated impact on the pro forma financial information would be immaterial.

Note 4—Adjustments to Reclassify Financial Statement Line Items to Our Presentation by Trianni Prior to Closing

Certain historical balances on the pro forma statements of income (loss) for the periods presented have been reclassified to conform to our presentation.

Note 5—Adjustments to the Unaudited Pro Forma Condensed Combined Statement of Income for the Year Ended December 31, 2020

[5A] To reflect the incremental straight-line amortization related to the increase in fair value of the license and technology over a period of four years and 20 years, respectively.

[5B] To reflect the accrued interest expense resulting from the Convertible Notes which are assumed to be outstanding from January 1, 2020 for the purposes of the pro forma financial information. The Convertible Notes are carried at amortized cost with an effective interest rate of 3.97%.

[5C] To reflect the tax impact of the pro forma adjustments at a preliminary blended federal and state statutory tax rate of 26%.

Note 6 —Earnings Per Share

The pro forma combined diluted earnings per share presented below for the year ended December 31, 2020 is determined by using the weighted average number of common shares and dilutive common share equivalents outstanding during the period. We have excluded the effect to earnings per share related to the Convertible Notes because including them would have been anti-dilutive.

(in thousands, except for per share amounts)			Year Ended December 31, 2020
Pro forma net earnings			$114,443
Less pro forma earnings allocated to Preferred Shareholders			(32,044)
Pro forma net earnings attributable to common shareholders			82,399
Pro forma basic weighted-average shares outstanding			159,195,023
Pro forma basic earnings per share			$0.52
Pro forma net earnings attributable to common shareholders			$114,443

USE OF PROCEEDS

We are filing the registration statement of which this prospectus forms a part to permit holders of the common shares described in the section “Selling Shareholders” to resell such shares. The selling shareholders will receive all of the net proceeds from this offering. We will not receive any of the proceeds from the sale of the shares being offered by the selling shareholders.

TABLE OF CONTENTS

SELLING SHAREHOLDERS

On June 9, 2021, certain of the selling shareholders identified in this prospectus purchased an aggregate of 11,900,000 common shares from the former holders of such shares in private resales not requiring registration under the Securities Act of 1933, as amended. In connection with such private resales, those selling shareholders have entered into securities purchase agreements pursuant to which they made representations, including as to their accredited investor status and investment intent with respect to the common shares purchased by them. Under such agreements, we have agreed to use commercially reasonable efforts to file the registration statement of which this prospectus forms a part to register such common shares within seven days of the settlement of such private resale transactions, and to use commercially reasonable efforts to cause such registration statement to be declared effective by the SEC within 90 days of its filing. 100,000 of the common shares offered by the remaining selling shareholder consist of existing shares in our Company. This prospectus covers the resale by the selling shareholders identified below of such common shares. The registration of the common shares of the selling shareholders through this prospectus constitutes a secondary offering and is not an offering by or on behalf of our company. We will not receive any proceeds from the resale of the common shares by the selling shareholders.

Except as described in the footnotes below, none of the selling shareholders has been an officer or director of ours or any of our predecessors or affiliates within the past three years. Except as described in the footnotes below, no selling shareholder had a material relationship with our company or any of our affiliates within the last three years.

The following table and the accompanying footnotes are based in part on information supplied to us by the selling shareholders. The table and footnotes assume that the selling shareholders will sell all of the shares listed. However, because the selling shareholders may sell all or some of their shares under this prospectus from time to time, or in another permitted manner, we cannot assure you as to the actual number of shares that will be sold by the selling shareholders or that will be held by the selling shareholders after completion of any sales. We do not know how long the selling shareholders will hold the shares before selling them.

The inclusion of any shares in this table does not constitute an admission of beneficial ownership by the persons named below.

TABLE OF CONTENTS

PLAN OF DISTRIBUTION

The selling shareholders, which as used herein includes donees, pledgees, transferees or other successors-in-interest selling common shares or interests in common shares received after the date of this prospectus from a selling shareholder as a gift, pledge, partnership distribution or other transfer, may, from time to time, sell, transfer or otherwise dispose of any or all of their common shares or interests in common shares on any stock exchange, market or trading facility on which the shares are traded or in private transactions. These dispositions may be at fixed prices, at prevailing market prices at the time of sale, at prices related to the prevailing market price, at varying prices determined at the time of sale, or at negotiated prices.

The selling shareholders may use any one or more of the following methods when disposing of shares or interests therein:

•	purchases by a broker-dealer as principal and resale by such broker-dealer for its own account pursuant to this prospectus;

•	ordinary brokerage transactions and transactions in which the broker solicits purchasers;

•	in underwriter transactions;

•	block trades in which the broker-dealer so engaged will attempt to sell the shares as agent but may position and resell a portion of the block as principal to facilitate the transaction or any other national securities exchange on which our securities are listed or traded;

•	an over-the-counter distribution in accordance with applicable rules;

•

through trading plans entered into by a selling shareholder pursuant to Rule 10b5-1 under the Exchange Act, that are in place at the time of an offering pursuant to this prospectus and any applicable prospectus supplement hereto that provide for periodic sales of their securities on the basis of parameters described in such trading plans;

•	to or through underwriters or broker-dealers;

•

in “at the market” offerings, as defined in Rule 415 under the Securities Act, at negotiated prices, at prices prevailing at the time of sale or at prices related to such prevailing market prices, including sales made directly on a national securities exchange or sales made through a market maker other than on an exchange or other similar offerings through sales agents;

•	in privately negotiated transactions;

•	through the writing of options (including put or call options), whether the options are listed on an options exchange or otherwise;

•	through the distribution of the securities by any shareholder to its partners, members or stockholders;

•	in short sales entered into after the effective date of the registration statement of which this prospectus is a part;

•	by pledge to secured debts and other obligations;

•	through a combination of any of the above methods of sale; or

•	any other method permitted pursuant to applicable law.

In addition, any shares that qualify for sale pursuant to Rule 144 may be sold under Rule 144 rather than pursuant to this prospectus.

The selling shareholders may, from time to time, pledge or grant a security interest in some or all of the common shares owned by them and, if they default in the performance of their secured obligations, the pledgees or secured parties may offer and sell the common shares, from time to time, under this prospectus, or under an amendment to this prospectus under Rule 424(b)(3) or other applicable provision of the Securities Act amending the list of selling shareholders to include the pledgee, transferee or other successors in interest as selling shareholders under this prospectus. The selling shareholders also may transfer the common shares in other circumstances, in which case the transferees, pledgees or other successors in interest will be the selling beneficial owners for purposes of this prospectus.

TABLE OF CONTENTS

In connection with the sale of our common shares or interests therein, the selling shareholders may enter into hedging transactions with broker-dealers or other financial institutions, which may in turn engage in short sales of the common shares in the course of hedging the positions they assume. The selling shareholders may also sell common shares short and deliver these securities to close out their short positions, or loan or pledge the common shares to broker-dealers that in turn may sell these securities. The selling shareholders may also enter into options or other transactions with broker-dealers or other financial institutions or the creation of one or more derivative securities which require the delivery to such broker-dealer or other financial institution of shares offered by this prospectus, which shares such broker-dealer or other financial institution may resell pursuant to this prospectus (as supplemented or amended to reflect such transaction).

The aggregate proceeds to the selling shareholders from the sale of the common shares offered by them will be the purchase price of the common shares less discounts or commissions, if any. Each of the selling shareholders reserves the right to accept and, together with their agents from time to time, to reject, in whole or in part, any proposed purchase of common shares to be made directly or through agents. We will not receive any of the proceeds from this offering.

The selling shareholders and any underwriters, broker-dealers or agents that are involved in selling the common shares or interests therein may be deemed to be “underwriters” within the meaning of Section 2(a)(11) of the Securities Act. In such event, any commissions received by such broker-dealers or agents and any profit on the resale of the shares purchased by them may be deemed to be underwriting commissions or discounts under the Securities Act. Each selling shareholder has informed us that it does not have any agreement or understanding, directly or indirectly, with any person to distribute the common shares. If a selling shareholder is deemed to be an “underwriter” within the meaning of the Securities Act, it will be subject to the prospectus delivery requirements of the Securities Act.

To the extent required, the common shares to be sold, the names of the selling shareholders, the respective purchase prices and public offering prices, the names of any agents, dealer or underwriter, any applicable commissions or discounts with respect to a particular offer will be set forth in an accompanying prospectus supplement or, if appropriate, a post-effective amendment to this registration statement that includes this prospectus.

In order to comply with the securities laws of some states, if applicable, the common shares may be sold in these jurisdictions only through registered or licensed brokers or dealers. In addition, in some states the common shares may not be sold unless it has been registered or qualified for sale or an exemption from registration or qualification requirements is available and is complied with.

We have advised the selling shareholders that the anti-manipulation rules of Regulation M under the Exchange Act may apply to sales of shares in the market and to the activities of the selling shareholders and their affiliates. In addition, we will make copies of this prospectus (as it may be supplemented or amended from time to time) available to the selling shareholders for the purpose of satisfying the prospectus delivery requirements of the Securities Act. The selling shareholders may indemnify any broker-dealer that participates in transactions involving the sale of the shares against certain liabilities, including liabilities arising under the Securities Act.

We have agreed with the selling shareholders to use commercially reasonable efforts to keep this registration statement of which this prospectus constitutes a part effective at all times until the earlier of (i) the date as of which such selling shareholder may sell all of its common shares without restriction pursuant to the last sentence of Rule 144(b)(1)(i) promulgated under the Securities Act (or successor thereto) or (ii) the date on which such selling shareholder shall have sold all its shares that it had purchased.

INDEPENDENT AUDITOR’S REPORT

Board of Directors

Trianni, Inc.

San Francisco, California

We have audited the accompanying financial statements of Trianni, Inc. (a California corporation) (the “Company”), which comprise the balance sheets as of December 31, 2018 and 2019, and the related statements of operations, convertible preferred stock and stockholders’ equity, and cash flows for the years then ended, and the related notes to the financial statements.

Management’s Responsibility for the Financial Statements

Management is responsible for the preparation and fair presentation of these financial statements in accordance with accounting principles generally accepted in the United States of America; this includes the design, implementation, and maintenance of internal control relevant to the preparation and fair presentation of financial statements that are free from material misstatement, whether due to fraud or error.

Auditor’s Responsibility

Our responsibility is to express an opinion on these financial statements based on our audits. We conducted our audits in accordance with auditing standards generally accepted in the United States of America. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free from material misstatement.

An audit involves performing procedures to obtain audit evidence about the amounts and disclosures in the financial statements. The procedures selected depend on the auditor’s judgment, including the assessment of the risks of material misstatement of the financial statements, whether due to fraud or error. In making those risk assessments, the auditor considers internal control relevant to the entity’s preparation and fair presentation of the financial statements in order to design audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the entity’s internal control. Accordingly, we express no such opinion. An audit also includes evaluating the appropriateness of accounting policies used and the reasonableness of significant accounting estimates made by management, as well as evaluating the overall presentation of the financial statements.

We believe that the audit evidence we have obtained is sufficient and appropriate to provide a basis for our audit opinion.

Opinion

In our opinion, the financial statements referred to above present fairly, in all material respects, the financial position of Trianni, Inc. as of December 31, 2018 and 2019, and the results of its operations and its cash flows for the years then ended in accordance with accounting principles generally accepted in the United States of America.

Change in Accounting Principle

As described in Note 2 to the financial statements, the Company has elected to change its method of accounting for revenue from contracts with customers as of January 1, 2018 due to the adoption of Accounting Standards Codification Topic 606. This adoption did not result in a cumulative adjustment to opening retained earnings as of January 1, 2018. Our opinion is not modified with respect to that matter.

Emphasis of Matter

As discussed in Note 2 to the financial statements, on March 11, 2020, the World Health Organization declared the novel string of coronavirus (COVID-19) a global pandemic and recommended containment and mitigation measures worldwide. The ultimate financial impact and duration of these events cannot be reasonably estimated at this time. Our opinion is not modified with respect to this matter.

ENDED SEPTEMBER 30, 2019 AND 2020 IS UNAUDITED)

1. BUSINESS OVERVIEW

Trianni, Inc. (the “Company”) was incorporated as a California corporation on August 25, 2008. The Company is a biotechnology company whose main activity is specializing in antibody discovery technology and selling licenses to it. The Company’s lead technology, the Trianni Mouse ^®, is a platform enabling efficient generation of fully-human monoclonal antibodies (the “Trianni Platform”). The Company’s transgenic platform leverages a novel approach to design made possible by advances in DNA synthesis and genomic modification technology. The Company is headquartered in San Francisco, California.

2. SIGNIFICANT ACCOUNTING POLICIES

Basis of Presentation

The financial statements of the Company are prepared in conformity with U.S. generally accepted accounting principles, or GAAP, and reflect the accounts and operations of the Company.

Use of Estimates

The preparation of financial statements in accordance with GAAP requires the Company to make estimates and assumptions that affect the reported amounts in the financial statements and accompanying notes. These estimates form the basis for judgments the Company makes about the carrying values of assets and liabilities that are not readily apparent from other sources. The Company bases its estimates and judgments on historical experience and on various other assumptions that the Company believes are reasonable under the circumstances. These estimates are based on management’s knowledge about current events and expectations about actions the Company may undertake in the future. Such estimates include, but are not limited to, revenue recognition, useful lives of property and equipment, fair value of the Company’s common stock, fair values of stock-based awards and income taxes. Actual results could differ materially from those estimates.

Unaudited Interim Financial Information

The accompanying interim balance sheet as of September 30, 2020, the interim statements of operations and cash flows for the nine months ended September 30, 2019 and 2020, the interim statements of convertible preferred stock and stockholders’ equity for the nine months ended September 30, 2020, and the financial data disclosed in these notes as of September 30, 2020 and for the nine months ended September 30, 2019 and 2020 are unaudited. The unaudited interim financial statements have been prepared on the same basis as the annual financial statements and, in the opinion of management, reflect all adjustments, which include only normal recurring adjustments, necessary for the fair statement of these interim financial statements. The results of operations for the nine months ended September 30, 2020 are not necessarily indicative of the results to be expected for the year ending December 31, 2020, or for any other future annual or interim period.

COVID-19

In March 2020, the World Health Organization declared the global novel coronavirus disease 2019 (“COVID-19”), outbreak a pandemic. While certain impacts of COVID-19 have been favorable to possible sale of the Company’s products and services, the Company cannot at this time predict the specific extent, duration, or full impact that the COVID-19 outbreak will have on its financial condition and operations. The impact of the COVID-19 coronavirus outbreak on the financial performance of the Company may depend on future developments, including the duration and spread of the outbreak and related governmental advisories and restrictions. In addition, the Company could see some limitations on employee resources that would otherwise be focused on its operations, including but not limited to sickness of employees or their families, the desire of employees to avoid contact with large groups of people, and increased reliance on working from home.

Certain Significant Risks and Uncertainties

The Company’s future results of operations involve a number of risks and uncertainties. Factors that could affect the Company’s future operating results and cause actual results to vary materially from expectations include, but

are not limited to, the achievement of the Company’s research and development activities, competition from other larger companies, protection of research and development results, strategic relationships, and dependence on key individuals.

Cash

Cash includes cash held in checking accounts, savings accounts, and certificates of deposit with an original maturity of three months or less held with high credit quality financial institutions in the United States. The Company considers all highly liquid investments with an original maturity of three months or less to be cash equivalents.

Marketable Securities

The Company invests its excess cash balances in bank certificates of deposits. Investments with original maturities greater than three months at the time of purchase are classified as marketable securities.

Concentrations of Risks

Financial instruments that potentially subject the Company to concentration of credit risk consist of cash, marketable securities and accounts receivable. The Company places its cash primarily with domestic financial institutions that are federally insured within statutory limits. The Company is exposed to credit risk in the event of default by financial institutions to the extent that cash balances are in excess of the amounts that are insured by the Federal Deposit Insurance Corporation (“FDIC”). As of December 31, 2018 and 2019, the Company had approximately $2.2 million and $0.9 million, respectively, deposited in a major financial institution in excess of FDIC insurance limitations. As of September 30, 2020, the Company had approximately $14.9 million deposited in a major financial institution in excess of FDIC insurance limitations. The Company has not experienced any losses to date.

The Company has not experienced any losses on its customer accounts and management believes the Company is not exposed to any significant risk of bad debt. As of December 31, 2018 and 2019, one customer represented 96% and 100%, respectively, of accounts receivable. As of September 30, 2020, two customers represented 57% and 34% of total accounts receivable, respectively. For the year ended December 31, 2018, three customers represented more than 10% of total revenue at approximately 24%, 14% and 11% of total revenue, respectively. For the year ended December 31, 2019, one customer represented more than 10% of total revenue at approximately 38%. For the nine months ended September 30, 2019, one customer represented more than 10% of revenue at approximately 40% of total revenue. For the nine months ended September 30, 2020, two customers represented more than 10% of revenue at approximately 59% and 19%, respectively, of total revenue.

Accounts Receivable and Allowance for Doubtful Accounts

Accounts receivable consist primarily of amounts due to the Company under the terms of license arrangements. It is the practice of the Company to provide for uncollectible accounts in the year the accounts are determined to be uncollectible. Based on management’s evaluation of accounts receivable, no allowance for doubtful accounts has been recorded in the accompanying balance sheets and the accompanying statements of operations do not reflect any bad debt expense.

Inventory

Inventory consists of mice inventory, including those sold to customers for breeding and/or those that are available to customers for non-breeding research purposes. Inventory is recorded at lower-of-cost or net realizable value. Inventory costs include direct costs associated with the development of mice. The Company does not have significant overhead costs. The Company regularly monitors for excess and obsolete inventory and

reduces the carrying value of inventory accordingly. The Company has not historically recorded any inventory write-downs and did not record any inventory write-downs during the years ended December 31, 2018 and 2019 or during the nine-months ended September 30, 2019 and 2020.

Property and Equipment, net

Property and equipment, net are stated at cost, less accumulated depreciation. Depreciation is computed using the straight-line method over the estimated useful lives of the assets as follows:

Laboratory equipment			5-10 years
Computer equipment			2 years

Maintenance and repairs are charged to operations when incurred. When property and equipment are sold or otherwise disposed of, the asset account and related accumulated depreciation account are relieved and any gain or loss in included in the results of operations.

Revenue Recognition

The Company generates revenue primarily from entering into licensing arrangements with customers, either under perpetual license or term license arrangements, under which the Company provides customers the rights to its human antibody discovery platform that is carried in the Trianni Mouse. The Company’s customers are primarily life science research pharmaceutical and biotechnology companies.

On January 1, 2018, the Company adopted the new accounting standard Accounting Standards Codification (“ASC”) 606, Revenue from Contracts with Customers ( “ASC 606”) using the modified retrospective method. Under the modified retrospective method, this guidance is applied to those contracts that were not completed as of January 1, 2018, with no restatement of contracts that were commenced and completed within fiscal years prior to January 1, 2018. The adoption of the new revenue standard had no impact on the opening retained earnings as of January 1, 2018 and, accordingly, no cumulative adjustment was required. Under ASC 606, revenue is recognized when control of promised goods or services is transferred to a customer in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. To determine revenue recognition for its arrangements with customers, the Company performs the following five steps: (i) identify the contract(s) with a customer; (ii) identify the performance obligations in the contract; (iii) determine the transaction price; (iv) allocate the transaction price to the performance obligations in the contract; and (v) recognize revenue when (or as) the entity satisfies a performance obligation.

At contract inception, the Company assesses the goods or services promised within each contract, identifies those that are performance obligations, and assesses whether each promised good or service is distinct. Performance obligations are considered distinct if they are both capable of being distinct and distinct within the context of the contract. In determining whether performance obligations meet the criteria for being distinct, the Company considers a number of factors, such as the degree of interrelation and interdependence between obligations, and whether or not the good or service significantly modifies or transforms another good or service in the contract. The Company has determined that the Trianni Mouse is not distinct from the perpetual or term licenses with which they are sold. The Company offers limited hours of support to its customers which has been deemed as an immaterial performance obligation.

Perpetual license agreements typically provide customers the right to use the Trianni Mouse for the development of antibodies and include the right to breed the mice and are comprised of a single performance obligation. Revenue associated with a perpetual license is recognized at a point in time when control of the Trianni Mouse is transferred. Term license agreements provide customers with the right to use the Company’s technology inherent in the Trianni Platform over a defined period of time, typically tied to specific projects, and prohibit customers the ability to use the Trianni Mouse for breeding purposes. Revenue under term licenses is recognized

over time, on a ratable basis, as access to the technology within the Trianni Platform is rendered. Subsequent mice sales are recognized as the mice are delivered. Term license agreements as well as research and development agreements may require milestone-based, measured by certain events, and/or royalty-based payments and the associated revenue is recognized at a point in time when certain milestones are reached. The Company also has certain arrangements in which, in addition to providing access to the Trianni Platform, a percentage of revenue generated from antibodies derived from the Trianni Mouse must be paid to the Company as a royalty or revenue sharing. Revenue share payments are recognized as revenue when received.

The transaction price is allocated to each performance obligation on a relative standalone selling price basis. In developing the standalone price for a performance obligation, the Company considers applicable market conditions and relevant entity-specific factors, including factors that were contemplated in negotiating the agreement with the customer and estimated costs. Generally, payments from customers are due when goods and services are transferred. For arrangements where the anticipated period between timing of transfer of goods and services and the timing of payment is one year or less, the Company has elected to not assess whether a significant financing component exists. Revenue is recognized only to the extent that it is probable that a significant reversal of the cumulative amount recognized will not occur in future periods.

The Company accepts mice returns and sends replacements only if the mice do not pass appropriate genotype testing or health standards and historically, the Company’s volume of returns has not been significant. Further, no warranties are provided for promised goods and services other than assurance type warranties.

Contract costs

Applying the practical expedient, the Company recognizes the incremental costs of obtaining contracts as an expense when incurred when the amortization period of the assets that otherwise would have been recognized is one year or less. These costs are included in sales and marketing and general and administrative expenses. The costs to fulfill the contracts are determined to be immaterial and are recognized as an expense when incurred.

Contract balances

Contract assets are generated when contractual billing schedules differ from revenue recognition timing and the Company records a contract receivable when it has an unconditional right to consideration. No contract asset balances were recorded for the periods presented in the accompanying financial statements.

Contract liabilities are recorded when cash payments are received or due in advance of performance. Contract liabilities consist of deferred revenue, where the Company has unsatisfied performance obligations. As of December 31, 2018 and 2019 and September 30, 2020, the contract liabilities were $4.4 million and $3.8 million and $2.0 million, respectively.

Disaggregation of Revenue

Based on the pattern of revenue recognition, the following table provides a disaggregation of revenue for the years ended December 31, 2018 and 2019 and for the nine months ended September 30, 2019 and 2020 (in thousands):

2. SIGNIFICANT ACCOUNTING POLICIES (continued)

Fair Value of Financial Instruments

The Company defines fair value as the exchange price that would be received from selling an asset or paid to transfer a liability in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. The Company measures its financial assets and liabilities at fair value at each reporting period using a fair value hierarchy which requires the Company to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. A financial instrument’s classification within the fair value hierarchy is based upon the lowest level of input that is significant to the fair value measurement. Three levels of inputs may be used to measure fair value:

•	Level 1—Observable inputs are unadjusted quoted prices in active markets for identical assets or liabilities.

•

Level 2—Observable inputs are quoted prices for similar assets and liabilities in active markets or inputs other than quoted prices which are observable for the assets or liabilities, either directly or indirectly through market corroboration, for substantially the full term of the financial instruments.

•

Level 3—Unobservable inputs which are supported by little or no market activity and which are significant to the fair value of the assets or liabilities. These inputs are based on the Company’s own assumptions used to measure assets and liabilities at fair value and require significant management judgment or estimation.

The carrying value of financial instruments approximates fair value. The Company estimates fair value of cash and cash equivalents, accounts receivable, other current assets, and liabilities based upon existing interest rates related to such assets and liabilities compared to the current market rates for instruments of similar nature and degree of risk.

Research and Development

Research and development (“R&D”) expenses consist primarily of personnel costs, including salaries, benefits and stock-based compensation, for laboratory personnel, depreciation of lab equipment, facility costs and the cost of supplies. In addition, the Company includes in R&D expense costs associated with mice breeding services. R&D costs are expensed as incurred.

Advertising Expenses

The Company expenses advertising expenses as they are incurred. Advertising expense for the years ended December 31, 2018 and 2019 were $372,000 and $337,000, respectively. Advertising expense for the nine months ended September 30, 2019 and 2020 were $263,000 and $127,000, respectively.

Stock-Based Compensation

The Company recognizes stock-based compensation expense for stock options awards to employees and nonemployees, on a straight-line basis over the requisite service period of the award, which is generally three years and which is generally equivalent to the vesting period. Certain of the Company’s stock options were fully vested on the date of grant. The fair value of each stock option is estimated on the date of grant using the Black-Scholes option-pricing model which includes various inputs, including Company estimates of expected volatility, term, risk-free rate and future dividends. Forfeitures are recognized as they occur.

The fair value of the shares of common stock underlying the Company’s stock options has historically been determined by management and approved by the Board of Directors. Because there has been no public market for the Company’s common stock, the Board of Directors has determined the fair value of the common stock at the time of grant of the option by considering a number of objective and subjective factors, including valuations performed by an unrelated third-party specialist, valuations of comparable companies, operating and financial

performance, the lack of liquidity of capital stock, recent private stock sale transactions (including the rights and preference of preferred stock relative to common stock), and general and industry-specific economic outlook. Valuations performed by third-party valuation specialists were done contemporaneously and used the methodologies, approaches, and assumptions consistent with the American Institute of Certified Public Accountants Accounting and Valuation Guide, Valuation of Privately-Held-Company Equity Securities Issued as Compensation (“AICPA Accounting and Valuation Guide”). In addition to the Company’s estimates of the fair value of common stock on the date of grant, the Company’s Black-Scholes option-pricing model uses various inputs, including expected term, expected volatility, risk-free interest rate, and expectations regarding future dividends. The following describes these additional key inputs:

Expected Term — The expected term represents the period that the Company’s stock options are expected to be outstanding. The Company determines the expected term using the simplified method.

Expected Volatility — The expected volatility is derived from the historical stock volatilities of several unrelated public companies within the Company’s industry that the Company considers to be comparable to the business over a period equivalent to the expected term of the stock option grants.

Risk-Free Interest Rate — The risk-free interest rate is based on the interest yield in effect at the date of grant for zero coupon U.S. Treasury notes with maturities approximately equal to the option’s expected term.

Dividend Rate — The expected dividend rate includes consideration of the Company’s historical dividend activity, if any.

Leases

The Company recognizes rent expense over the term of an operating lease, starting when the property is made available for use by the owner/landlord. When a lease contains a predetermined fixed rent escalation, the related rent expense is recognized on a straight-line basis and the difference between the recognized rent expense and the amounts paid under the lease are recorded as deferred rent included in accrued expenses and other current liabilities on the balance sheets.

Income Taxes

The Company accounts for income taxes in accordance with Financial Accounting Standards Board (“FASB”) ASC 740, Accounting for Income Taxes, which requires an asset and liability approach under which deferred tax assets and liabilities arise from the temporary differences between the tax basis of an asset or liability and its reported amount in the financial statements, as well as from net operating loss and tax credit carryforwards.

Deferred tax amounts are determined by using the tax rates expected to be in effect when the taxes will actually be paid or refunds received, as provided for under currently enacted tax law. A valuation allowance is established when necessary to reduce deferred tax assets to the amount expected to be realized.

Significant judgment is required in determining any valuation allowance recorded against deferred tax assets. In assessing the need for a valuation allowance, the Company considers all available evidence, including past operating results, estimates of future taxable income, and the feasibility of tax planning strategies. In the event that the Company changes its determination as to the amount of deferred tax assets that can be realized, it will adjust the valuation allowance with a corresponding impact to the provision for income taxes in the period in which such determination is made.

The Company also follows the provisions of ASC 740-10, Accounting for Uncertainty in Income Taxes. ASC 740-10 prescribes a comprehensive model for the recognition, measurement, presentation and disclosure in financial statements of any uncertain tax positions that have been taken or expected to be taken on a tax return. No liability related to uncertain tax positions is recorded on the consolidated financial statements. It is the Company’s policy to include penalties and interest expense related to income taxes as part of the provision for income taxes.

Recently Adopted Accounting Pronouncements

In June 2020, the FASB issued ASU No 2020-05 (“ASU 2020-05”), Revenue from Contracts with Customers (Topic 606) and Leases (Topic 842). ASU 2020-05 defers, for one year, the required effective date of ASC 606 for certain entities that have not yet issued their financial statements (or made financial statements available for issuance) reflecting the adoption of ASC 606. Those entities may elect to adopt the guidance for annual reporting periods beginning after December 15, 2019, and for interim reporting periods within annual reporting periods beginning after December 15, 2020. The Company elected to adopt ASC 606 as of January 1, 2018 with no impact to its opening retained earnings as of January 1, 2018.

In June 2018, the Financial Accounting Standards Board (“FASB”) issued ASU No. 2018-07, Compensation—Stock Compensation (Topic 718): Improvements to Nonemployee Share-Based Payment Accounting. ASU 2018-07 simplifies the accounting for share-based payment transactions in which a grantor acquires goods or services to be used or consumed in operations from a nonemployee and aligns with the current requirements for share-based awards granted to employees. The Company adopted this standard beginning January 1, 2018. The adoption of ASC 2018-07 did not have a material impact on its financial statements.

In August 2016, the FASB issued ASU 2016-15, Statement of Cash Flows (Topic 230) provides guidance on eight specific cash flow issues, thereby reducing the diversity in practice in how certain transactions are classified in the statement of cash flows. The amendments in ASU 2016-15 were effective for annual reporting periods beginning after December 15, 2018. The Company’s adoption of this standard did not have an impact on the financial statements.

Recently Issued Accounting Pronouncements

ASU 2020-05 also defers the effective date for one year for entities in the “all other” category and public not-for-profit entities that have not yet issued their financial statements (or made financial statements available for issuance) reflecting the adoption of ASC 842. Therefore, under the amendments, ASC 842 is effective for entities within the “all other” category for fiscal years beginning after December 15, 2021, and interim periods within fiscal years beginning after December 15, 2022. Additionally, ASC 842 is effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years, for public NFP entities that have not yet issued financial statements (or made available for issuance) reflecting the adoption of ASC 842. Early application continues to be permitted, which means that an entity may choose to implement ASC 842 before those deferred effective dates. The Company has not yet determined the potential impact of the new standard on its financial statements.

In December 2019, the FASB issued ASU No. 2019-12, Income Taxes (Topic 740) : Simplifying the Accounting for Income Taxes (ASU 2019-12), which simplifies the accounting for income taxes. This guidance is effective for fiscal years beginning after December 31, 2021 with early adoption permitted. The Company has not yet determined the potential impact of the new standard on its financial statements.

In May 2019, the FASB issued ASU No. 2019-05, Financial Instruments – Credit Losses (Topic 326), Targeted Transition Relief, which amends the transition guidance for ASU 2016-13. The ASU provides entities with the option to irrevocably elect the fair value option in Subtopic 825-10 on an instrument-by- instrument basis. This standard is effective for years beginning after December 15, 2019, with early adoption permitted. The Company has not yet determined the potential effects of this ASU on its financial statements.

In August 2018, the FASB issued ASU No. 2018-13, Fair Value Measurement (Topic 820) – Changes to the Disclosure Requirements for Fair Value Measurement. The ASU eliminates certain disclosure requirements for fair value measurements for all entities and modifies some disclosure requirements. This ASU is effective for nonpublic entities beginning after December 15, 2019, with early adoption permitted. The Company has not yet determined the potential effects of this ASU on its financial statements.

2. SIGNIFICANT ACCOUNTING POLICIES (continued)

In July 2018, the FASB issued ASU No. 2018-09, Codification Improvements. The ASU amendments represent changes to clarify, correct errors, or make minor improvements to the Accounting Standards Codification. Some amendments do not require transition guidance and are effective immediately. Amendments that require transition guidance have various effective dates. The amendments applicable to and effective for the Company’s 2019 fiscal years did not have a significant impact on the Company’s financial statements. The Company has not yet determined the full effects of the remaining amendments, which are effective beginning after December 15, 2019, within this ASU on its financial statements, however, many of the remaining amendments are not expected to be applicable to the Company.

In July 2017, the FASB issued ASU 2017-11, Earnings Per Share (Topic 260), Distinguishing Liabilities from Equity (Topic 480) and Derivatives and Hedging (Topic 815): I. Accounting for Certain Financial Instruments with Down Round Features; II. Replacement of the Indefinite Deferral for Mandatorily Redeemable Financial Instruments of Certain Nonpublic Entities and Certain Mandatorily Redeemable Noncontrolling Interests with a Scope Exception (“ASU 2017-11”). Part I of this update addresses the complexity of accounting for certain financial instruments with down round features. Down round features are features of certain equity- linked instruments (or embedded features) that result in the strike price being reduced on the basis of the pricing of future equity offerings. Current accounting guidance creates cost and complexity for entities that issue financial instruments (such as warrants and convertible instruments) with down round features that require fair value measurement of the entire instrument or conversion option. Part II of this update addresses the difficulty of navigating Topic 480, Distinguishing Liabilities from Equity, because of the existence of extensive pending content in the FASB Accounting Standards Codification. This pending content is the result of the indefinite deferral of accounting requirements about mandatorily redeemable financial instruments of certain nonpublic entities and certain mandatorily redeemable noncontrolling interests. The amendments in Part II of this update do not have an accounting effect. The amendments in Part I of this update are effective for fiscal years beginning after December 15, 2019, and interim periods within fiscal years beginning after December 15, 2020. Early adoption is permitted for all entities, including adoption in an interim period. The Company is currently assessing the potential impact of adopting ASU 2017-11 on its consolidated financial statements and disclosures.

In February 2016, the FASB issued ASU No. 2016-02, Leases (“Topic 842”), which supersedes the guidance in former ASC 840, Leases. The new standard, as amended by subsequent ASUs on Topic 842 and recent extensions issued by the FASB in response to COVID-19, requires lessees to apply a dual approach, classifying leases as either finance or operating leases based on the principle of whether or not the lease is effectively a financed purchase by the lessee. This classification will determine whether lease expense is recognized based on an effective interest method or on a straight-line basis over the term of the lease. A lessee is also required to record a right-of-use asset and a lease liability for all leases with a term of greater than 12 months regardless of their classification. Leases with a term of 12 months or less will be accounted for similar to existing guidance for operating leases today. Topic 842, is effective for annual periods beginning after December 15, 2021, with early adoption permitted. The Company has not yet determined the full effects of this ASU on its financial statements.

6. STOCKHOLDERS’ EQUITY (continued)

Convertible Preferred Stock

A summary of the authorized, issued and outstanding redeemable convertible preferred stock (collectively, the “Preferred Stock”) as of December 31, 2019, consisted of the following (in thousands, except per share data):

	As of December 31, 2019
	Shares Authorized	Shares Issued and Outstanding	Liquidation Preference
Series A	1,609,417	1,609,417	$425
Series B	2,395,325	2,367,633	1,282
Series C	2,064,900	1,471,240	1,425
Total	6,069,642	5,448,290	$3,132

The holders of the preferred stock have various rights and preferences as follows:

Voting Rights — Each holder of preferred stock is entitled to votes equal to the number of whole shares of common stock into which the shares of preferred stock are convertible. The holders of preferred stock shall be entitled to elect (voting as a single class on an as-converted basis) one director of the Company. The holders of common stock shall be entitled to elect (voting as a single class) two directors of the Company.

Dividends — The holders of preferred stock have priority to the holders of common stock, and are entitled to receive, on a pari passu basis, a noncumulative cash dividend at the rate of $0.0158 per share for Series A, $0.0325 per share for Series B, and $0.0581 per share for Series C, per annum, if and when declared by the Board. After payment in full of such amounts as set forth above, any additional dividends declared will be distributed among all holders of preferred stock and common stock on an as-if-converted basis.

On July 20, 2020, by unanimous written consent, the Company’s Board of Directors declared dividends of approximately $6.5 million to its preferred and common stockholders. Dividends for the Series A, Series B, and Series C were declared at per share amounts of $0.0158, $0.0325, and $0.0581, respectively, and dividends for all holders of preferred stock and common stock on an as-if-converted basis were declared at a per share amount of $0.50.

Conversion and Redemption — Each share of preferred stock is convertible, at any time at the option of the stockholder, into one share of common stock, subject to certain anti-dilution or other adjustments. In a deemed liquidation event, the conversion rights shall terminate at the close of business on the last full day preceding the date fixed for the payment of any such amounts distributable on such event to the holders of preferred stock. The convertible preferred stock is not mandatorily redeemable upon demand by the holders of the preferred stock.

Each share of convertible preferred stock is convertible, at the option of the holder, into such number of fully paid and nonassessable shares of common stock as is determined by dividing $0.26407 for each share of Series A, $0.54168 for each share of Series B, or $0.96857 for each share of Series C. Each share of Series A, Series B and Series C automatically converts into the number of shares of common stock into which such shares are convertible at the then-effective conversion ratio upon the earlier of (i) closing of a firm commitment underwritten public offering in which the gross proceeds is at least $10,000,000 and the public offering price is at least $5.00 per share or (ii) the consent of the holders of at least a majority of the outstanding shares of Series A, Series B and Series C, voting together as a single class.

Liquidation — The holders of the convertible preferred stock are entitled to have their shares redeemed upon the occurrence of certain redemption events. A liquidation or winding up of the Company, a greater than 50% change of control, or sale of substantially all of its assets, would constitute a redemption event. The redemption events have been concluded as being outside the control of the Company, accordingly, all shares of preferred stock have been presented outside of permanent equity. Further, the Company has not adjusted the carrying values of the

6. STOCKHOLDERS’ EQUITY (continued)

Series A, Series B and Series C convertible preferred stock to the redemption value of such shares, since it is uncertain whether or when a redemption event will occur. Adjustments to increase the carrying value to the redemption values will be made when it becomes probable that such redemption will occur.

In the event of any liquidation, dissolution, or winding up of the Company, whether voluntary or involuntary, the holders of the preferred shares shall be entitled to receive, prior and in preference to any distribution of any of the assets of the Company to the holders of common stock, (i) an amount equal to $0.26407 (as adjusted for recapitalizations) for Series, A, $0.54168 (as adjusted for recapitalizations) for Series B, and $0.96857 (as adjusted for recapitalizations for Series C, plus (ii) any accrued or declared but unpaid dividends on such shares. If the assets available for distribution to the holders of the preferred shares shall be insufficient to pay the preferential amount in full, then the entire assets and funds of the company legally available for distribution shall be distributed ratably to the holders of the preferred stock in proportion to the preferential amount each such holder is otherwise entitled to receive, only until the aggregate proceeds received by such holder equals $0.66018 per share of Series A, $1.3542 per share for Series B, and $2.42143 per share for Series C .

Protective Provisions — So long as shares of preferred stock remain outstanding, the Company must obtain approval from a majority of the then outstanding holders of preferred stock (voting as a separate class) in order to (i) amend or repeal any provision of, or add any provision to, the Company’s Articles of Incorporation if such action would materially and adversely alter or change the rights, preferences or privileges or powers of, or the restrictions provided for the benefit of the preferred stock; (ii) authorize or issue any new class or series of stock having any preference or priority as to dividends or assets superior to or on a party with any such preference or priority of the preferred stock; (iii) sell all or substantially all of its property or business or merge into or consolidate with any other corporation or effect any other transaction or series of related transactions in which more than 50% of the voting power of the Company is disposed of; and (iv) liquidate or dissolve the Company.

7. STOCK-BASED COMPENSATION

In 2015, the Company’s Board of Directors approved the amendment to the 2009 Stock Plan (the “Plan”), under which there are 5,142,778 shares available for issuance. The purpose of the Plan is to provide incentives to attract and retain the best available persons for positions of substantial responsibility and to provide additional inventive to employees, directors and consultants and to promote the success of the Company’s business. The Plan provides for different forms of benefits including incentive stock options, nonqualified stock options, and restricted stock awards. Options granted under the Plan to employees continue to vest until the last day of employment and generally vest over three years and expire 10 years from the date of grant. Employees generally forfeit their rights to exercise vested options after 12 months following their termination of employment. During the year ended December 31, 2018, all of the Company’s stock options with early exercise provisions became fully vested, thus, as of December 31 2018 and 2019 and September 30, 2020, there were no stock options subject to a repurchase right as a result of having been exercised prior to becoming fully vested.

The exercise price for options granted under the Plan must generally be equal to at least 100% of the fair value of the Company’s common stock at the date of grant, as determined by the Board of Directors. The exercise price of an incentive stock option granted under the Plan to a ten percent stockholder must be at least equal to 110% of the fair value of the Company’s common stock at the date of grant, as determined by the Board of Directors.

The Company’s stock options were fully vested as of December 31, 2019, thus, did record any stock-based compensation for the nine months ended September 30, 2020. For the years ended December 31, 2018 and 2019 and for the nine months ended September 30, 2019, stock-based compensation expense included in the statements of operations is as follows (in thousands):

more likely than not to be realized upon the ultimate settlement. The Company’s policy is to recognize interest and penalties related to the underpayment of income taxes as a component of income tax expense or benefit. The benefit for income taxes for the years ended December 31, 2018 and 2019 consisted of the following (in thousands):

	2018	2019
Federal
Current	$389	$(62)
Deferred	(644)	(327)
State and local
Current	4	32
Deferred	(113)	(192)
Income tax benefit	$(364)	$(549)

As at December 31, 2018 and 2019, the Company’s deferred tax assets and liabilities consisted of the effects of temporary differences attributable to the following (in thousands):

	2018	2019
Deferred Tax Assets:
Federal & State NOL Carryforward	$618	$468
Research & Other Credits	109	314
Deferred Revenue	55	473
Stock Based Compensation	161	247
Total Deferred Tax Assets	943	1,502
Valuation allowance	—	—
Net deferred tax assets	943	1,502
Deferred Tax Liabilities:
Fixed assets	(58)	(58)
Deferred state income tax	(24)	(64)
Total gross deferred tax liabilities	(82)	(122)
Net deferred tax assets	$861	$1,380

In assessing the realizability of deferred tax assets, management considers whether it is more likely than not that some portion or all of the deferred tax assets will not be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during the periods in which those temporary differences become deductible. Based on its historical earnings track and forecasted future earnings, the Company believes it is more likely than not that all its deferred tax assets as at December 31, 2018 and December 31, 2019, respectively, will be realized prior to their expiration. Accordingly, a valuation allowance has not been established on the Company’s net deferred tax assets.

As of December 31, 2018, the Company had federal net operating loss carryforwards of $2,592,000 and $881,000, respectively. As of December 31, 2019, the Company had federal and state net operating loss carryforwards of $1,924,000 and $772,000 respectively. The federal net operating losses will be carried forward indefinitely. Portions of the state net operating loss carryforwards will begin to expire in 2038.

Pursuant to IRC Section 382 and 383, use of the Company’s U.S. federal and state net operating loss and research and development income tax credit carry forwards may be limited in the event of a cumulative change in ownership of more than 50% within a three-year period. The Company has not completed an analysis under IRC Sections 382 and 383, and therefore net operating loss carry forwards reflected in the deferred tax assets at

December 31, 2018 have not been adjusted to reflect Section 382 and 383 limitations. If a change in ownership were to have occurred, additional net operating loss and tax credit carry forwards could be eliminated or restricted. If eliminated, the related asset would be removed from the deferred tax asset schedule with a corresponding reduction in the valuation allowance.

As of December 31, 2018 and 2019, the Company had federal credits of approximately $87,000 and $217,000, respectively, which will begin to expire in 2038. State research credits as of December 31, 2018 and 2019 of approximately $22,000 and $97,000, respectively, have no expiration date. These tax credits are subject to the same ownership change limitations.

On December 22, 2017, the Tax Cuts and Jobs Act (the “2017 Tax Act”) was enacted. The 2017 Tax Act includes a number of changes to existing U.S. tax laws that impact the Company, most notably a reduction of the U.S. corporate income tax rate from 35 percent to 21 percent for tax years beginning after December 31, 2017. As the Company’s opening deferred tax balances were calculated as at January 1, 2018, no remeasuring of deferred tax assets and/or liabilities to reflect the reduction in corporate income tax rate was required.

In response to the COVID-19 pandemic, the Coronavirus Aid, Relief and Economic Security Act (CARES Act) was signed into law in March 2020. The CARES Act lifts certain deduction limitations originally imposed by the Tax Cuts and Jobs Act of 2017 (2017 Tax Act). Corporate taxpayers may carryback net operating losses (NOLs) originating during 2018 through 2020 for up to five years, which was not previously allowed under the 2017 Tax Act. The CARES Act also eliminates the 80% of taxable income limitations by allowing corporate entities to fully utilize NOL carryforwards to offset taxable income in 2018, 2019 or 2020. Taxpayers may generally deduct interest up to the sum of 50% of adjusted taxable income plus business interest income (30% limit under the 2017 Tax Act) for tax years beginning January 1, 2019 and 2020. The CARES Act allows taxpayers with alternative minimum tax credits to claim a refund in 2020 for the entire amount of the credits instead of recovering the credits through refunds over a period of years, as originally enacted by the 2017 Tax Act.

In addition, the CARES Act raises the corporate charitable deduction limit to 25% of taxable income and makes qualified improvement property generally eligible for 15-year cost-recovery and 100% bonus depreciation. The enactment of the CARES Act will not be applicable to the Company until 2020 and is expected to have a material impact on the Company’s ability to utilize its federal net operating loss carryforwards and tax credit carryforwards due to the five-year carryback rule, among other matters. The Company is also evaluating other impacts the CARES Act will have on its financial statements.

The Company files income tax returns in the US federal jurisdiction as well as various state jurisdictions. The Company’s federal income tax returns from 2017 are open to audit by the Internal Revenue Service. Under IRC 38(c), the Company is limited in the utilization of its Federal Research and Development Tax Credit in the year. The Company has therefore utilized the Federal Research and Development Tax Credit against 75% of its net taxable income that exceeds $25,000 in the year.

9. RELATED PARTY TRANSACTIONS

Licensing Agreement

On April 2, 2015, the Company entered into a license agreement with respect to the Trianni Platform with Austrianni GmbH (“Austrianni”), a biotechnology company founded in 2015 to develop novel antibody-based therapeutics for the prevention and treatment of multidrug-resistant tuberculosis. In exchange for the license, Austrianni issued shares of capital stock to the Company representing approximately 10% of Austrianni total share capital on a fully diluted basis.

Item 14.

Indemnification of Directors and Officers

We are governed by the Business Corporations Act (British Columbia), or BCBCA. Under the BCBCA, and our articles, we may (or must, in the case of our articles) indemnify all eligible parties against all eligible penalties to which such person is or may be liable, and we must, after the final disposition of an eligible proceeding, pay the expenses actually and reasonably incurred by such person in respect of that proceeding. Each director is deemed to have contracted with the Company on the terms of indemnity contained in our articles.

For the purposes of such an indemnification:

“eligible party,” in relation to the Company, means an individual who

•	is or was a director or officer of the Company;

•	is or was a director or officer of another corporation

•	at a time when the corporation is or was an affiliate of the Company, or

•	at the request of the Company; or

•	at the request of the Company, is or was, or holds or held a position equivalent to that of, a director or officer of a partnership, trust, joint venture or other unincorporated entity and includes the heirs and personal or other legal representatives of that individual;

“eligible penalty” means a judgment, penalty or fine awarded or imposed in, or an amount paid in settlement of, an eligible proceeding;

“eligible proceeding” means a proceeding in which an eligible party or any of the heirs and personal or other legal representatives of the eligible party, by reason of the eligible party being or having been a director or officer of, or holding or having held a position equivalent to that of a director or officer of, the Company or an associated corporation:

•	is or may be joined as a party, or

•	is or may be liable for or in respect of a judgment, penalty or fine in, or expenses related to, the proceeding;

“expenses” includes costs, charges and expenses, including legal and other fees, but does not include judgments, penalties, fines or amounts paid in settlement of a proceeding; and

“proceeding” includes any legal proceeding or investigative action, whether current, threatened, pending or completed.

In addition, under the BCBCA, the Company may pay, as they are incurred in advance of the final disposition of an eligible proceeding, the expenses actually and reasonably incurred by an eligible party in

respect of that proceeding, provided that the Company first receives from the eligible party a written undertaking that, if it is ultimately determined that the payment of expenses is prohibited by the restrictions noted below, the eligible party will repay the amounts advanced.

II-1

TABLE OF CONTENTS

Notwithstanding the provisions of the Company’s articles noted above, the Company must not indemnify an eligible party or pay the expenses of an eligible party, if any of the following circumstances apply:

•	if the indemnity or payment is made under an earlier agreement to indemnify or pay expenses and, at the time that the agreement to indemnify or pay expenses was made, the Company was prohibited from giving the indemnity or paying the expenses by its articles;

•	if the indemnity or payment is made otherwise than under an earlier agreement to indemnify or pay expenses and, at the time that the indemnity or payment is made, the Company is prohibited from giving the indemnity or paying the expenses by its articles;

•	if, in relation to the subject matter of the eligible proceeding, the eligible party did not act honestly and in good faith with a view to the best interests of the Company or the associated corporation, as the case may be; or

•	in the case of an eligible proceeding other than a civil proceeding, if the eligible party did not have reasonable grounds for believing that the eligible party’s conduct in respect of which the proceeding was brought was lawful.

In addition, if an eligible proceeding is brought against an eligible party by or on behalf of the Company or by or on behalf of an associated corporation, the Company must not do either of the following:

•	indemnify the eligible party in respect of the proceeding; or

•	pay the expenses of the eligible party in respect of the proceeding.

Notwithstanding any of the foregoing, and whether or not payment of expenses or indemnification has been sought, authorized or declined under the BCBCA or the articles of the Company, on the application of the Company or an eligible party, the Supreme Court of British Columbia may do one or more of the following:

•	order the Company to indemnify an eligible party against any liability incurred by the eligible party in respect of an eligible proceeding;

•	order the Company to pay some or all of the expenses incurred by an eligible party in respect of an eligible proceeding;

•	order the enforcement of, or any payment under, an agreement of indemnification entered into by the Company;

•	order the Company to pay some or all of the expenses actually and reasonably incurred by any person in obtaining an order under this section; or

•	make any other order the court considers appropriate.

The BCBCA and our articles authorize us to purchase and maintain insurance for the benefit of an eligible party against any liability that may be incurred by reason of the eligible party being or having been a director or officer of, or holding or having held a position equivalent to that of a director or officer of, the Company, a current or former affiliate of the Company or a corporation, partnership, trust, joint venture or other unincorporated entity at the request of the Company.

In addition, we have entered, or will enter, into separate indemnity agreements with each of our directors and officers pursuant to which we agree to indemnify and hold harmless our directors and officers against any and all liability, loss, damage, cost or expense in accordance with the terms and conditions of the BCBCA and our articles.

The recipients of the securities in each of these transactions represented their intentions to acquire the securities for investment only and not with a view to or for sale in connection with any distribution thereof and appropriate legends were placed upon the share certificates issued in these transactions. All of the foregoing securities are deemed restricted securities for purposes of the Securities Act.

Undertakings.

The undersigned registrant hereby undertakes:

(1)	To file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement:

(i)	To include any prospectus required by section 10(a)(3) of the Securities Act;

(ii)

To reflect in the prospectus any facts or events arising after the effective date of the registration statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the registration statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the Securities and Exchange Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than a 20 percent change in the maximum aggregate offering price set forth in the “Calculation of Registration Fee” table in the effective registration statement; and

(iii)

To include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in the registration statement;

provided, however, that paragraphs (a)(1)(i), (a)(1)(ii) and (a)(1)(iii) above do not apply if the information required to be included in a post-effective amendment by those paragraphs is contained in reports filed with or furnished to the Securities and Exchange Commission by the registrant pursuant to Section 13 or Section 15(d) of the Securities Exchange Act of 1934 that are incorporated by reference in the registration statement, or is contained in a form of prospectus filed pursuant to Rule 424(b) that is part of the registration statement.

(2)

That, for the purpose of determining any liability under the Securities Act, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(3)	To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.

II-4

TABLE OF CONTENTS

(4)	That, for the purpose of determining liability under the Securities Act to any purchaser:

(A)	Each prospectus filed by the registrant pursuant to Rule 424(b)(3) shall be deemed to be part of the registration statement as of the date the filed prospectus was deemed part of and included in the registration statement; and

(B)

Each prospectus required to be filed pursuant to Rule 424(b)(2), (b)(5) or (b)(7) as part of a registration statement in reliance on Rule 430B relating to an offering made pursuant to Rule 415(a)(1)(i), (vii), or (x) for the purpose of providing the information required by Section 10(a) of the Securities Act shall be deemed to be part of and included in the registration statement as of the earlier of the date such form of prospectus is first used after effectiveness or the date of the first contract of sale of securities in the offering described in the prospectus. As provided in Rule 430B, for liability purposes of the issuer and any person that is at that date an underwriter, such date shall be deemed to be a new effective date of the registration statement relating to the securities in the registration statement to which that prospectus relates, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. Provided, however, that no statement made in a registration statement or prospectus that is part of the registration statement or made in a document incorporated or deemed incorporated by reference into the registration statement or prospectus that is part of the registration statement will, as to a purchaser with a time of contract of sale prior to such effective date, supersede or modify any statement that was made in the registration statement or prospectus that was part of the registration statement or made in any such document immediately prior to such effective date.

(5)

That, for purposes of determining any liability under the Securities Act, each filing of the registrant’s annual report pursuant to Section 13(a) or 15(d) of the Securities Exchange Act of 1934 (and, where applicable, each filing of an employee benefit plan’s annual report pursuant to Section 15(d) of the Securities Exchange Act of 1934) that is incorporated by reference in the registration statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(6)

Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers and controlling persons of the registrant pursuant to the foregoing provisions, or otherwise, the registrant has been advised 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 the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act and will be governed by the final adjudication of such issue.
