Note 1 - Business Organization, Nature of Operations

Description of Business

Energous Corporation d/b/a Energous Wireless Power Solutions (the “Company”) has developed scalable, over-the-air wireless power networks (“WPN”) technology, consisting of semiconductor chipsets, software controls, hardware designs and antennas, that enable radio frequency (“RF”) based charging for Internet of Things (“IoT”) devices. The WPN technology has a broad spectrum of capabilities to enable the next generation of wireless power networks, delivering power and data in a seamless device portfolio, enabling unprecedented levels of visibility, control, and intelligent business automation. This includes near field and at-a-distance wireless charging with multiple power levels at various distances. The Company’s wireless power transmitter and receiver technologies deliver continuous access to wireless power, helping drive a new generation of battery-free devices for asset and inventory tracking and management – from retail sensors, electronic shelf labels, and asset trackers, to air quality monitors, motion detectors, and more.

The Company believes its technology is innovative in its approach, in that the Company is developing solutions that charge IoT devices using RF technology. To date, the Company has developed and released to production multiple transmitters and receivers, including prototypes and partner production designs. The transmitters vary based on form, factor and power specifications and frequencies, while the receivers are designed to support a myriad of wireless charging applications including:


Device Type	Application
RF Tags	Cold Chain, Asset Tracking, Medical IoT
IoT Sensors	Cold Chain, Logistics, Asset Tracking
Electronic Shelf Labels	Retail and Industrial IoT

The first WPN end product featuring the Company’s technology entered the market in 2019. The Company started shipping its first at-a-distance wireless PowerBridges for commercial IoT applications and proofs of concept in the fourth quarter of 2021 and expects additional wireless power enabled products to be released as the Company’s business moves forward.

Reverse Stock Split

On June 14, 2023, at the Company’s 2023 annual meeting of stockholders, the Company’s stockholders approved a proposal to effect a reverse stock split of the Company’s common stock by a ratio not to exceed 1-for-20.

On August 15, 2023, the Company announced that its Board of Directors had determined to set the reverse stock split ratio at 1-for-20 and that the Company’s common stock would begin trading at the split-adjusted price beginning August 16, 2023. Upon effectiveness of the reverse stock split, every twenty shares of issued and outstanding common stock held were converted into one share of common stock. No fractional shares were distributed as a result of the reverse stock split and stockholders were entitled to a cash payment in lieu of fractional shares. Additionally, the par value of the Company’s common stock did not change.

All information presented herein, unless otherwise indicated herein, reflects the 1-for-20 reverse stock split of the Company’s outstanding shares of common stock, and unless otherwise indicated, all such amounts and corresponding conversion price or exercise price data set forth herein have been adjusted to give effect to such reverse stock split.

Note 2 – Liquidity and Management Plans

During the three and nine months ended September 30, 2024, the Company recorded revenue of $0.2 million and $0.3 million, respectively. During the three and nine months ended September 30, 2023, the Company recorded revenue of $0.2 million and $0.4 million, respectively. During the three and nine months ended September 30, 2024, the Company recorded net losses of $3.4 million and $14.3 million, respectively. During the three and nine months ended September 30, 2023, the Company recorded net losses of $4.1 million and $14.8 million, respectively. Net cash used in operating activities was $14.9 million and $15.9 million for the nine months ended September 30, 2024 and 2023, respectively. As of September 30, 2024, the Company had cash and cash equivalents of $1.5 million. The Company is currently meeting its liquidity requirements through the proceeds of securities offerings, including the ATM Program (as defined in Note 7 below), which securities offerings generated aggregate net proceeds of $6.9 million during 2023 and $2.5 million during the nine months ended September 30, 2024.

Based on current operating levels, the Company will need to raise additional funds in the next 12 months by selling additional equity or incurring debt.

As the Company gains traction in the market with its new technology and continues to invest capital in transitioning and scaling the business from research and development of new technologies to commercial production, there can be no assurance that its available resources and revenue generated from its business operations will be sufficient to sustain its operations. Accordingly, the Company expects to pursue additional financing, which could include offerings of equity or debt securities, bank financings, commercial agreements with customers or strategic partners, and other alternatives, depending upon market conditions. There is no assurance that such financing will be available on terms that the Company would find acceptable, or at all. If the Company is unsuccessful in implementing this plan, the Company will be required to make further cost and expense reductions or modifications to its on-going and strategic plans.

The market for products using the Company’s technology is broad and evolving, but remains nascent and unproven, so the Company’s success is dependent upon many factors, including customer acceptance of its existing products, technical feasibility of future products, regulatory approvals, the development of complementary technologies, competition and global market fluctuations.

Note 3 – Summary of Significant Accounting Policies

Basis of Presentation

The accompanying unaudited condensed financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“US GAAP”), and pursuant to the accounting and disclosure rules and regulations of the U.S. Securities and Exchange Commission (the “SEC”). Certain information and note disclosures have been condensed or omitted pursuant to such rules and regulations. The unaudited condensed 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 a fair presentation of the period presented. The results of operations for the three and nine months ended September 30, 2024 are not necessarily indicative of the results to be expected for the year ending December 31, 2024, or for other future periods.

These interim unaudited condensed financial statements should be read in conjunction with the audited financial statements and notes thereto for the fiscal year ended December 31, 2023 included in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2023, filed with the SEC on March 28, 2024. The accounting policies used in preparing these interim unaudited condensed financial statements are consistent with those described in the Company’s December 31, 2023 audited financial statements.

Reclassifications

Certain reclassifications have been made to the fiscal year 2023 condensed balance sheet to conform to the fiscal year 2024 presentation. The reclassifications had no impact on total assets, total liabilities, or stockholders’ equity.

Table of Contents

Note 3 – Summary of Significant Accounting Policies, continued

Use of Estimates

The preparation of financial statements in conformity with US GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent liabilities at the date of the financial statements as well as the reported expenses during the reporting periods.

The Company’s significant estimates and assumptions include the valuation of stock-based compensation instruments, recognition of revenue, inventory valuation, fair value of warrant liabilities and the valuation allowance on deferred tax assets. Some of these judgments can be subjective and complex, and, consequently, actual results may differ from these estimates. Although the Company believes that its estimates and assumptions are reasonable, they are based upon information available at the time the estimates and assumptions were made. Actual results could differ from those estimates.

Cash, Cash Equivalents and Restricted Cash

The Company considers all short-term, highly liquid investments with an original maturity at the date of purchase of three months or less to be cash equivalents. The Company maintains cash balances that may be uninsured or in deposit accounts that exceed Federal Deposit Insurance Corporation limits. The Company maintains its cash deposits with major financial institutions. The Company reports restricted cash on its balance sheet to disclose the amount reserved for a specific purpose aside from ordinary business operations. The Company had restricted cash as collateral for the Company’s corporate credit card program which was discontinued during the second quarter of 2024. As of September 30, 2024 and December 31, 2023, the carrying value of restricted cash was $0 and $0.1 million, respectively.

Warrants

The Company accounts for warrants as either equity-classified or liability-classified instruments based on an assessment of the warrant’s specific terms and applicable authoritative guidance in Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) 480, “Distinguishing Liabilities from Equity” (“ASC 480”) and ASC 815, “Derivatives and Hedging” (“ASC 815”). The assessment considers whether the warrants are freestanding financial instruments pursuant to ASC 480, meet the definition of a liability pursuant to ASC 480, and whether the warrants meet all of the requirements for equity classification under ASC 815, including whether the warrants are indexed to the Company’s common stock, among other conditions for equity classification. This assessment, which requires the use of professional judgment, is conducted at the time of warrant issuance and as of each subsequent quarterly period end date while the warrants are outstanding.

For issued or modified warrants that meet all of the criteria for equity classification, the warrants are required to be recorded as a component of additional paid-in capital at the time of issuance. For issued or modified warrants that do not meet all the criteria for equity classification, the warrants are required to be recorded as a liability at their initial fair value on the date of issuance, and each balance sheet date thereafter. Changes in the estimated fair value of the warrants are recognized as a non-cash gain or loss on the statements of operations. The fair value of the warrants is estimated using an appropriate valuation model. Such warrant classification is also subject to re-evaluation at each reporting period.

Offering costs associated with warrants classified as liabilities are expensed as incurred and are presented as offering cost related to warrant liability in the statement of operations. Offering costs associated with the sale of warrants classified as equity are charged against the proceeds received.

Note 3 – Summary of Significant Accounting Policies, continued

Fair Value

The Company follows ASC 820, “Fair Value Measurements” (“ASC 820”), which establishes a common definition of fair value to be applied when US GAAP requires the use of fair value, establishes a framework for measuring fair value, and requires certain disclosure about such fair value measurements.

ASC 820 establishes a hierarchy for inputs used in measuring fair value that maximizes the use of observable inputs and minimizes the use of unobservable inputs by requiring that observable inputs be used when available. Observable inputs are inputs that market participants would use in pricing the asset or liability based on market data obtained from sources independent of the Company. Unobservable inputs are inputs that reflect the Company’s assumptions about what market participants would use in pricing the asset or liability based on the best information available in the circumstances. The hierarchy is broken down into three levels based on the reliability of inputs as follows:

●

Level 1: Observable inputs such as quoted prices in active markets for identical assets or liabilities to which the Company has access at a measurement date.

●

Level 2: Observable inputs other than Level 1 quoted prices that are observable for the asset or liability, either directly or indirectly; these include quoted prices for similar assets or liabilities in an active market, quoted prices for identical assets and liabilities in markets that are not active, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities.

●

Level 3: Unobservable inputs for which little or no market data exists and for which the Company must develop its own assumptions regarding the assumptions that market participants would use in pricing the asset or liability, including assumptions regarding risk.

Because of the uncertainties inherent in the valuation of assets or liabilities for which there are no observable inputs, those estimated fair values may differ significantly from the values that may have been used had a ready market for the assets or liabilities existed.

The carrying amounts of the Company’s financial assets and liabilities, such as cash, cash equivalents, prepaid expenses and other current assets, and accounts payable and accrued expenses, are an approximate of their fair values because of the short maturity of these instruments. The Company’s warrant liability recognized at fair value on a recurring basis is a level 3 measurement (see Note 10 – Fair Value Measurements).

Revenue Recognition

The Company follows ASC 606, “Revenue from Contracts with Customers” (“Topic 606”).

In accordance with Topic 606, the Company recognizes revenue using the following five-step approach:

Identify the contract with a customer.

Identify the performance obligations in the contract.

Determine the transaction price of the contract.

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

Recognize revenue when or as the performance obligations are satisfied.

Note 3 – Summary of Significant Accounting Policies, continued

The Company’s revenue consists of its single segment of wireless charging system solutions. The wireless charging system revenue consists of revenue from product development projects and production-level systems. During the three and nine months ended September 30, 2024, the Company recognized $0.2 million and $0.3 million, respectively, in revenue. During the three and nine months ended September 30, 2023, the Company recognized $0.2 million and $0.4 million, respectively, in revenue.

The Company records revenue associated with product development projects that it enters into with certain customers. In general, these product development projects are complex, and the Company does not have certainty about its ability to achieve the project milestones. The achievement of a milestone is dependent on the Company’s performance obligation and requires acceptance by the customer. The Company recognizes this revenue at the point in time at which the performance obligation is met. The payment associated with achieving the performance obligation is generally commensurate with the Company’s effort or the value of the deliverable and is nonrefundable. Any deferred revenue is recognized upon achievement of the performance obligation or expiration of a support agreement.

Inventory

The Company follows ASC 330, “Inventory” (“Topic 330”) to account for its inventory, which includes finished goods ready for sale, work in process and raw materials, at the lower of cost or net realizable value. Net realizable value is calculated at the end of each reporting period and adjustment, if needed, is made. At the point of loss recognition, a new lower cost basis for that inventory is established and subsequent changes in facts and circumstances do not result in the restoration or increase in the new cost basis.

Research and Development

Research and development expenses are charged to operations as incurred. For internally developed patents, all patent costs are expensed as incurred as research and development expense. Patent application costs, which are generally legal costs, are expensed as research and development costs until such time as the future economic benefits of such patents become more certain. The Company incurred research and development costs of $1.7 million and $6.5 million for the three and nine months ended September 30, 2024, respectively. The Company incurred research and development costs of $2.5 million and $8.4 million for the three and nine months ended September 30, 2023, respectively.

Stock-Based Compensation

The Company accounts for equity instruments issued to employees, board members and contractors in accordance with accounting guidance that requires awards to be recorded at their fair value on the date of grant and amortized over the vesting period of the award. The Company amortizes compensation costs on a straight-line basis over the requisite service period of the award, which is typically the vesting term of the equity instrument issued.

Under the ESPP, employees may purchase a limited number of shares of the Company’s common stock at a 15% discount from the lower of the closing market prices measured on the first and last days of each half-year period. The Company recognizes stock-based compensation expense for the fair value of the purchase options, as measured on the grant date.

Income Taxes

Tax benefits are recognized only for tax positions that are more likely than not to be sustained upon examination by tax authorities. The amount recognized is measured as the largest amount of benefit that is greater than 50 percent likely to be realized upon settlement. A liability for “unrecognized tax benefits” is recorded for any tax benefits claimed in the Company’s tax returns that do not meet these recognition and measurement standards. As of September 30, 2024, no liability for unrecognized tax benefits was required to be reported. The guidance from ASC 740, “Income Taxes” also discusses the classification of related interest and penalties on income taxes. The Company’s policy is to record interest and penalties on uncertain tax positions as a component of income tax expense. No interest or penalties were recorded during the three or nine months ended September 30, 2024 and 2023. The Company files income tax returns with the United States, California, Texas and Arizona governments.

Net Loss Per Common Share

Basic net loss per share is computed by dividing net loss available to common stockholders by the weighted average number of shares of common stock outstanding during the period. Diluted earnings per share is computed using the weighted average number of common shares and, if dilutive, potential common shares outstanding during the period. Potential common shares consist of the incremental common shares issuable upon the exercise of stock options and warrants (using the treasury stock method), the vesting of RSUs and PSUs and the enrollment of employees in the ESPP. The computation of diluted loss per share excludes potentially dilutive securities of 1,950,212 and 597,020, as outlined in the table below, for the three and nine months ended September 30, 2024 and 2023, respectively, because their inclusion would be anti-dilutive.

PSUs	—	2,500
Total potentially dilutive securities	1,950,212	597,020

For the three and nine months ended September 30, 2024, the table above includes 1,020,409 warrants expiring on February 20, 2029, which have an exercise price of $1.84 per share and 412,500 warrants expiring on March 28, 2029, which, as of September 30, 2024, have an exercise price of $0.56 per share. For the three and nine months ended September 30, 2023, the table above includes 83,333 warrants that expired on March 1, 2024, which had an exercise price of $200 per share, and 412,500 warrants expiring on March 28, 2029, which, as of September 30, 2024, have an exercise price of $0.56 per share.

Leases

The Company determines if an arrangement is a lease at the inception of the arrangement. The Company applies the short-term lease recognition exemption and recognizes lease payments in profit or loss at lease commencement for facility or equipment leases that have a lease term of 12 months or less and do not include a purchase option whose exercise is reasonably certain. Operating leases are included in operating lease right-of-use (“ROU”) assets and operating lease liabilities.

ROU assets represent the right to use an underlying asset for the lease term, and lease liabilities represent the obligation to make lease payments arising from the lease. Operating lease ROU assets and liabilities are measured and recorded at the later of the adoption date, January 1, 2019, or the service commencement date based on the present value of lease payments over the lease term. The Company uses the implicit interest rate when readily determinable; however, most leases do not establish an implicit rate, so the Company uses an estimate of the incremental borrowing rate based on the information available at the time of measurement. Lease expense for lease payments is recognized on a straight-line basis over the lease term. See Note 6 – Commitments and Contingencies, Operating Leases for further discussion of the Company’s operating leases.

Segments

The Company has one operating segment and one reportable segment as its chief operating decision maker, who is its Chief Executive Officer and Chief Financial Officer, reviews financial information on a regular basis for purposes of allocating resources and evaluating financial performance. All long-lived assets are located in the United States and substantially all revenue is attributed to customers based in the United States.

Recently Issued Pronouncements

In November 2023, the FASB issued Accounting Standards Update (“ASU”) No. 2023-07, “Segment Reporting” (“Topic 280”), Improvements to Reportable Segment Reporting. This standard is intended to improve reportable segment disclosure requirements, primarily through enhanced disclosures about significant segment expenses This standard is effective for the Company’s annual fiscal period beginning January 1, 2024 and for the Company’s interim periods beginning January 1, 2025. Adoption of this standard will not likely have a material impact on the Company’s financial statements.

In December 2023, the FASB issued ASU No. 2023-09, “Income Taxes” (“Topic 740”), Improvements to Income Tax Disclosures. This standard is intended to enhance the transparency and usefulness of income tax disclosures to better assess how an entity’s operations and related tax risks and tax planning and operational opportunities affect its tax rate and prospects for future cash flows. This standard is effective for the Company’s annual fiscal period beginning January 1, 2025. Adoption of this standard will not likely have a material impact on the Company’s financial statements.

Management has reviewed other recently issued accounting pronouncements issued or proposed by the FASB and does not believe any of these accounting pronouncements has had or will have a material impact on the condensed financial statements.

Operating Leases

San Jose Lease

On May 20, 2022, the Company signed a lease amendment to the existing lease for its office space at its corporate headquarters in San Jose, California, extending the term of the lease for an additional three years. Upon signing the lease amendment, the Company recorded a new ROU lease asset of $2.1 million and operating lease liability of $2.1 million, using a present value discount rate of 3.0%, which was used as an incremental borrowing rate for a hypothetical fully collateralized real estate transaction. As of January 1, 2024, the discount rate was adjusted to 8% in order to reflect a realistic incremental borrowing rate at lease commencement. The adjustment created a one-time reduction to the ROU lease asset and operating lease liability of approximately $51,000. Upon expiration of the original lease on September 30, 2022, the new monthly lease payment starting October 1, 2022 is approximately $59,000, subject to annual escalations up to a maximum monthly lease payment of approximately $62,000. On July 31, 2024, the Company signed an additional lease amendment where the monthly payments through the remainder of 2024 were reduced to approximately $37,000 and the monthly payments from January 2025 through September 2025 were increased to approximately $76,000. No other changes were made to the existing lease. As a result of this amendment, the Company revalued its ROU lease asset to $0.8 million and its operating lease liability to $0.8 million on July 31, 2024. The Company recorded lease expense of $0.2 million and $0.6 million for the three and nine months ended September 30, 2024, respectively. The Company recorded lease expense of $0.2 million and $0.6 million for the three and nine months ended September 30, 2023, respectively.

Operating Lease Commitments

The Company follows ASC 842, “Leases” (“Topic 842”) and recognizes the required ROU assets and operating lease liabilities on its balance sheet. The Company anticipates having future total lease payments of $0.8 million during the period from the fourth quarter of 2024 to the third quarter of 2025. As of September 30, 2024, the Company has total operating lease ROU assets of $0.7 million and current portion of operating lease liabilities of $0.8 million. The weighted average remaining lease term is 1.0 years as of September 30, 2024.

A reconciliation of undiscounted cash flows to lease liabilities recognized as of September 30, 2024 is as follows (in thousands):


For the year ending December 31,	Amount

Hosted Design Software Agreement

In June 2024, the Company renewed an electronic design automation software in a hosted environment license agreement through the end of 2025 under which the Company is required to remit quarterly payments of approximately $52,000 through the fourth quarter of 2025. During the three and nine months ended September 30, 2024, the Company recorded expense of approximately $52,000 and $500,000, respectively, under this agreement.

Litigations, Claims, and Assessments

The Company is from time to time involved in various disputes, claims, liens and litigation matters arising in the normal course of business. While the outcome of these disputes, claims, liens and litigation matters cannot be predicted with certainty, after consulting with legal counsel, management does not believe that the outcome of these matters will have a material adverse effect on the Company’s combined financial position, results of operations or cash flows.

MBO Bonus Plan

On March 15, 2018, the Company’s Board of Directors (the “Board”), on the recommendation of the Board’s Compensation Committee (the “Compensation Committee”), approved the Energous Corporation MBO Bonus Plan (“Bonus Plan”) for executive officers of the Company. To be eligible to receive a bonus under the Bonus Plan, an executive officer must be continuously employed throughout the applicable performance period, in good standing, and achieve the performance objectives selected by the Compensation Committee.

Under the Bonus Plan, the Compensation Committee was responsible for selecting the amounts of potential bonuses for executive officers, the performance metrics used to determine whether any such bonuses would be paid and determining whether those performance metrics had been achieved.

The Company did not record any expense under the Bonus Plan during the three or nine months ended September 30, 2024. During the three and nine months ended September 30, 2023, the Company recorded $0.1 million and $0.4 million, respectively, in expense under the Bonus Plan. As of December 31, 2023, the Company had $0.5 million in bonuses earned during 2023 that had not yet been paid and was included in accrued expenses. As of September 30, 2024, the Company had paid all amounts accrued under the Bonus Plan.

On May 30, 2024, the Board, on the recommendation of the Compensation Committee, approved the 2024 Corporate Bonus Plan (the “2024 Bonus Plan”), whereby employees’ bonuses will be based upon achievement of performance objectives set by the Compensation Committee and paid annually. Employees must be continuously employed throughout the applicable performance period and payment date and achieve the performance objectives.

Under the 2024 Bonus Plan, the Compensation Committee is responsible for selecting the amounts of potential bonuses for executive officers and vice presidents, the performance metrics used to determine whether any such bonuses will be paid and determining whether those performance metrics have been achieved. As of September 30, 2024, the Company recorded approximately $0.1 million under the 2024 Bonus Plan.

Severance and Change in Control Agreement

On March 15, 2018, the Compensation Committee approved a form of Severance and Change in Control Agreement that the Company may enter into with executive officers.

On May 30, 2024, the Compensation Committee approved a new form of Severance Agreement and Change in Control Agreement (“Severance Agreement”) that the Company may enter into with executive officers and vice presidents (each, an “Executive”). Under the Severance Agreement, if an Executive party thereto is terminated without cause or in a qualifying change in control termination, the Company agrees to pay the Executive three to twelve months of that Executive’s monthly base salary and 25% to 100% of the Executive’s target bonus, and to accelerate the vesting of 25% to 100% of the Executive’s unvested equity awards. If an Executive elects continued coverage under the Consolidated Omnibus Budget Reconciliation Act of 1985, as amended (“COBRA”) the Company will pay the full amount of the Executive’s premiums under the Company’s health, dental and vision plans, including coverage for the Executive’s eligible dependents, for the three-to-twelve-month period, as applicable, following the Executive’s termination.

Strategic Alliance Agreement

In November 2016, the Company and Dialog Semiconductor plc (“Dialog”), a related party, entered into a Strategic Alliance Agreement (“Alliance Agreement”) for the manufacture, distribution and commercialization of products incorporating the Company’s wire-free charging technology (“Licensed Products”). Pursuant to the terms of the Alliance Agreement, the Company agreed to engage Dialog as the exclusive supplier of the Licensed Products for specified fields of use, subject to certain exceptions (the “Company Exclusivity Requirement”). Dialog agreed to not distribute, sell or work with any third party to develop any competing products without the Company’s approval. In addition, both parties agreed on a revenue sharing arrangement and to collaborate on the commercialization of Licensed Products based on a mutually-agreed upon plan. Each party will retain all of its intellectual property rights.

The Alliance Agreement had an initial term of seven years, with automatic renewal annually thereafter unless terminated by either party upon 180 days’ prior written notice. The Company could terminate the Alliance Agreement at any time after the third anniversary of the Alliance Agreement upon 180 days’ prior written notice to Dialog, or if Dialog breached certain exclusivity obligations. Dialog could terminate the Alliance Agreement if sales of Licensed Products did not meet specified targets. The Company Exclusivity Requirement had a termination date of the earlier of January 1, 2021 or the occurrence of certain events relating to the Company’s pre-existing exclusivity obligations. The Company Exclusivity Requirement renewed automatically on an annual basis unless the Company and Dialog agreed to terminate the requirement.

On September 20, 2021, the Company was notified by Dialog, which had been recently acquired by Renesas Electronics Corporation (“Renesas”), that it was terminating the Alliance Agreement between the Company and Dialog. There is a wind down period included in the Alliance Agreement which concluded in September 2024. During the wind down period, the Alliance Agreement’s terms applied to the Company’s products that are covered by certain existing customer relationships, except that the parties’ respective exclusivity rights have terminated.

Employee Stock Purchase Plan

In April 2015, the Board approved the Energous Corporation Employee Stock Purchase Plan (“ESPP”), under which 30,000 shares of common stock were reserved for purchase by the Company’s employees, subject to the approval by the Company’s stockholders. On May 21, 2015, the Company’s stockholders approved the ESPP. On June 12, 2024, the Company’s stockholders approved the amendment and restatement of the ESPP to increase the number of shares reserved for issuance under the ESPP by 6,200 shares. Under the ESPP, employees may designate an amount not less than 1% but not more than 10% of their annual compensation for the purchase of Company shares. No more than 375 shares may be purchased by an employee under the ESPP during an offering period. Excess contributions during an offering period are refunded to the employees. An offering period is six months in duration commencing on or about January 1 and July 1 of each year. The exercise price of options purchased under the ESPP is the lesser of 85% of the fair market of the common stock on the first business day of the offering period and 85% of the fair market value of the common stock on the applicable exercise date.

As of September 30, 2024, 17,166 shares of common stock remain eligible to be issued under the ESPP. Employees contributed approximately $5,000 through payroll withholdings to the ESPP as of September 30, 2024 for the current offering period which concludes on December 31, 2024.

Stock Option Activity

In February 2022, the Board granted the Company’s former Chief Executive Officer 15,000 stock options at an exercise price of $25.40 per share with half of the options vesting on the second anniversary of the vesting start date and a quarter of the options vesting on each of the two following anniversaries. Under the former Chief Executive Officer’s Severance Agreement, unvested awards vesting within 18 months of termination were accelerated and became vested on March 26, 2024. Consequently, 3,750 options became vested and another 3,750 options were forfeited. This resulted in stock-based compensation expense of approximately $0 and $53,000 during the three and nine months ended September 30, 2024, respectively. As of September 30, 2024, all stock options granted to the former Chief Executive Officer were forfeited.

No stock options were granted during the three and nine months ended September 30, 2023 and 2024.

Restricted Stock Units (“RSUs”)

During the nine months ended September 30, 2024, the Board granted its Interim Principal Executive officer and Chief Financial Officer 77,000 RSUs. Each RSU represents the contingent right to one share of common stock of the Company. The RSU awards vest over four years.

During the nine months ended September 30, 2024, the Compensation Committee granted directors an aggregate of 6,000 RSUs for service on the Board. These RSU awards vest on the one-year anniversary of the grant date.

During the nine months ended September 30, 2024, the Board granted employees an aggregate of 468,000 RSUs, which vest over four years.

Under the former Chief Executive Officer’s Severance Agreement, unvested RSUs vesting within 18 months of termination were accelerated and vested on March 26, 2024. Consequently, 3,017 RSUs vested resulting in stock-based compensation expense of approximately $0 and $77,000 during the three and nine months ended September 30, 2024, respectively.

As of September 30, 2024, the unamortized fair value of the RSUs was $0.9 million. The unamortized amount will be expensed over a weighted average period of 2.8 years. A summary of the activity related to RSUs for the nine months ended September 30, 2024 is presented below:

Performance Stock Units (“PSUs”)

PSUs are grants that vest upon the achievement of certain performance goals. The goals are commonly related to the Company’s revenue and achievement of sales and marketing goals.

Table of Contents

Note 8 – Stock-Based Compensation, continued

On July 20, 2022, the Board granted the Company’s former Chief Executive Officer 14,350 PSUs under the Company’s 2015 Performance Share Unit Plan pursuant to the terms of the former executive’s offer letter with the Company (See Note 6 – Commitments and Contingencies). The 14,350 PSUs that had been approved were to vest as follows: (a) up to 9,350 PSU shares would vest on December 31, 2022, subject to the former executive’s continued service as Chief Executive Officer and the achievement, to be determined in the Compensation Committee’s sole discretion, by the former executive of certain performance metrics previously determined by the Compensation Committee and approved by the Board, and (b) up to an additional 2,500 PSU shares would vest on each of December 31, 2023 and December 31, 2024, subject to continued service as Chief Executive Officer and the achievement, to be determined in the Compensation Committee’s sole discretion, of certain performance metrics.

There was no PSU activity for the three or nine months ended September 30, 2024 and 2023. The 2,500 PSU shares that were reserved for grant during 2024 per the former executive’s offer letter with the Company, as well as the 1,250 shares reserved for potential outperformance by the former executive of 2024 goals were returned to the 2015 Performance Share Unit Plan for future issuance upon the former executive’s termination of service with the Company.

Employee Stock Purchase Plan

The current offering period under the ESPP began on July 1, 2024 and will conclude on December 31, 2024. The recently completely offering period under the ESPP started on January 1, 2024 and concluded on June 30, 2024. During the year ended December 31, 2023, there were two offering periods. The first offering period began on January 1, 2023 and concluded on June 30, 2023. The second offering period began on July 1, 2023 and concluded on December 31, 2023.

The weighted average grant-date fair value of the purchase option for each designated share purchased under the ESPP was approximately $0.63 per share and $4.05 per share for the nine months ended September 30, 2024 and 2023, respectively, which represents the fair value of the option, consisting of three main components: (i) the value of the discount on the enrollment date, (ii) the proportionate value of the call option for 85% of the stock and (iii) the proportionate value of the put option for 15% of the stock. The Company recognized compensation expense for the ESPP of approximately $1,000 and $4,000 for the three and nine months ended September 30, 2024, respectively. The Company recognized compensation expense for the ESPP of approximately $1,000 and $42,000 for the three and nine months ended September 30, 2023, respectively.

The Company estimated the fair value of ESPP purchase options granted during the nine months ended September 30, 2024 and 2023 using the Black-Scholes option pricing model. The fair values of ESPP purchase options granted were estimated using the following assumptions:

Note 9 – Warrant Liability

2023 Warrants

In March 2023, the Company issued 412,500 warrants to purchase up to 412,500 shares of its common stock. The 2023 Warrants have a six-year term and were exercisable upon issuance on March 28, 2023. Each 2023 Warrant was initially exercisable for one share of the Company’s common stock at a price of $8.00 per share. As of September 30, 2024, the exercise price was adjusted to $0.56 per share (subject to further adjustment in certain circumstances, including in the event of stock dividends and splits; recapitalizations; change of control transactions; and issuances or sales of, or agreements to issue or sell, shares of common stock or common stock equivalents at a price per share less than the then-applicable exercise price for the 2023 Warrants, including sales under the ATM Program, the “Exercise Price”).

In the event of certain transactions such as a merger, consolidation, tender offer, reorganization, or other change in control, if holders of common stock are given any choice as to the consideration to be received, the holder of each 2023 Warrant shall be given the same choice of alternate consideration. In the event of certain transactions that are not within the Company’s control, such as a merger, consolidation, tender offer, reorganization, or other change in control of the Company, each holder of a 2023 Warrant shall be entitled to receive the same form of consideration at the Black Scholes value of the unexercised portion of the 2023 Warrant that is being offered and paid to holders of common stock, including the option to exercise the 2023 Warrants on a “cashless basis”.

If the Company issues additional shares of common stock or equity-linked securities for a consideration per share less than the Exercise Price, then such Exercise Price will be reduced to a new lower price pursuant to the terms of the 2023 Warrants. Additionally, if the Exercise Price of any outstanding derivative securities is modified by the Company such that such security’s modified exercise price is below the Exercise Price, the Exercise Price will adjust downward pursuant to the terms of the 2023 Warrant. This provision would not apply for stock or stock equivalents which fall under shares that qualify for exempt issuance, such as if the Company adjusted the option exercise price for an option granted to an employee, officer, or director.

The Company accounted for the 2023 Warrants in accordance with the derivative guidance contained in ASC 815-40, as the warrants did not meet the criteria for equity treatment. The Company believes that the adjustments to the Exercise Price is based on a variable that is not an input to the fair value of a “fixed-for-fixed” option as defined under ASC 815-40, and thus the 2023 Warrants are not eligible for an exception from derivative accounting. As such, the 2023 Warrants were initially measured at fair value and recorded as a liability in the amount of $3.1 million. As of September 30, 2024, all 2023 Warrants were outstanding. As of September 30, 2024, the fair value of the warrant liability was $0.2 million. The Company recorded a change in fair value of the warrant liability of $0.2 million and $0.4 million for the three and nine months ended September 30, 2024, respectively. The Company recorded a change in fair value of the warrant liability of $0.8 million and $2.7 million for the three and nine months ended September 30, 2023, respectively.

2023 Warrants

The Company utilizes a Monte Carlo simulation model for the 2023 Warrants at each reporting period, with changes in fair value recognized in the statements of operations. The estimated fair value of the 2023 Warrant liability is determined using Level 3 inputs. Inherent in a Monte Carlo simulation model are assumptions related to expected share-price volatility, expected life, risk-free interest rate, and dividend yield.

The key inputs into the Monte Carlo simulation model for the 2023 Warrants are as follows:


	As of September 30,			As of June 30,			As of March 31,			As of September 30,			As of June 30,			As of March 31,

Agile Subordinated Loan Agreement

Effective October 1, 2024, the Company entered into a subordinated business loan agreement (the “Original Loan Agreement”) with Agile Capital Funding, LLC and Agile Lending, LLC (collectively, the “Lender”), which provided for an initial term loan of $525,000, with the ability to receive additional term loans of up to $1.6 million, subject to certain conditions (such loans, the “Term Loan”). Principal and interest on the initial term loan in the aggregate amount of $756,000 was to be repaid in weekly payments of $27,000 commencing on October 14, 2024 and fully repaid on or before the maturity date of April 21, 2025. The Term Loan would be expressly subordinated to the Company's obligations on certain senior indebtedness of the Company as provided in the Original Loan Agreement. Effective only upon the occurrence and continuance of an event of default under the Loan Agreement, the Company would grant the Lender a security interest in certain collateral, excluding intellectual property, of the Company as set forth in the Original Loan Agreement.

Effective November 5, 2024, the Company entered into an amended subordinated business loan agreement with the Lender (the “Amended Loan Agreement”) to refinance the Term Loan. The Amended Loan Agreement provides for a new term loan of $997,000, with the ability to receive additional term loans of up to $1.6 million, subject to certain conditions (such new loans, the “New Term Loan”). Principal and interest on the initial new term loan in the aggregate amount of $1,415,740 is to be repaid in weekly payments of approximately $39,000 and fully repaid on or before the maturity date of July 17, 2025. The proceeds of the New Term Loan were used to repay in full the Term Loan described above, which had a balance of $648,000 on November 5, 2024, and the remaining proceeds will be used for working capital. The New Term Loan will be expressly subordinated to the Company's obligations on certain senior indebtedness of the Company as provided in the Amended Loan Agreement. The Amended Loan Agreement replaces the Original Loan Agreement and otherwise contains substantially the same terms as the Original Loan Agreement.

Regulation A Offering

On October 11, 2024, the Company filed a Regulation A Offering Statement on Form 1-A with an offering of a maximum of 5,000,000 Units (the “Regulation A Offering”), with each Unit consisting of one share of Series A Convertible Preferred Stock and three common stock purchase warrants, two to each purchase one share of common stock at an exercise price of $1.50 per share and one to purchase one share of common stock at $2.00 per share, for an aggregate of 5,000,000 shares of Series A Convertible Preferred Stock (and 10,000,000 shares of common stock underlying the shares of Series A Convertible Preferred Stock) and warrants to purchase up to an aggregate of 10,000,000 shares of common stock at an exercise price of $1.50 per share and 5,000,000 shares of common stock at an exercise price of $2.00 per share, at an offering price of $1.50 per Unit, for a maximum offering amount of $7,500,000.

Overview

We have developed scalable, over-the-air wireless power networks (“WPN”) technology, consisting of semiconductor chipsets, software controls, hardware designs and antennas, that enable radio frequency (“RF”) based charging for Internet of Things (“IoT”) devices. The WPN technology has a broad spectrum of capabilities to enable the next generation of wireless power networks, delivering power and data in a seamless device portfolio, enabling unprecedented levels of visibility, control, and intelligent business automation. This includes near field and at-a-distance wireless charging with multiple power levels at various distances. Our wireless power transmitter and receiver technologies deliver continuous access to wireless power, helping drive a new generation of battery-free devices for asset and inventory tracking and management – from retail sensors, electronic shelf labels, and asset trackers, to air quality monitors, motion detectors, and more.

We believe our technology is innovative in its approach, in that we are developing solutions that charge IoT devices using RF technology. To date, we have developed and released to production multiple transmitters and receivers, including prototypes and partner production designs. The transmitters vary based on form, factor and power specifications and frequencies, while the receivers are designed to support a myriad of wireless charging applications, including:


Device Type	Application
RF Tags	Cold Chain, Asset Tracking, Medical IoT
IoT Sensors	Cold Chain, Logistics, Asset Tracking
Electronic Shelf Labels	Retail and Industrial IoT

The first WPN end product featuring our technology entered the market in 2019. We started shipping our first at-a-distance wireless PowerBridges for commercial IoT applications and proofs of concept in the fourth quarter of 2021, and we expect additional wireless power enabled products to be released as we move our business forward.

Critical Accounting Policies and Estimates

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 and the disclosure of contingent liabilities at the date of the financial statements as well as the reported expenses during the reporting periods.

Some of these judgments can be subjective and complex, and, consequently, actual results may differ from these estimates. Although we believe that its estimates and assumptions are reasonable, they are based upon information available at the time the estimates and assumptions were made. Actual results could differ from those estimates.

During the three months ended September 30, 2024, management believes there have been no significant changes to the items that we disclosed within our critical accounting policies and estimates in “Management’s Discussion and Analysis of Financial Condition and Results of Operations” in our Annual Report on Form 10-K for the year ended December 31, 2023.

Table of Contents

Revenue. During the three months ended September 30, 2024 and 2023, we recorded revenue of $0.2 million and $0.2 million, respectively. Revenue for the three months ended September 30, 2024 consisted primarily of transmitter sales volume versus the majority of revenue being derived from non-recurring engineering fees and the sale of semiconductor chips during the same period in 2023. This shift in revenue focus represents the beginning of the Company’s transition from research and development to commercial production of its PowerBridge transmitters.

Costs and Expenses and Loss from Operations. Costs and expenses are made up of cost of revenue, research and development, sales and marketing, general and administrative and severance expense. Loss from operations for the three months ended September 30, 2024 and 2023 were $3.6 million and $5.1 million, respectively.

Cost of Revenue:


	Three months ended September 30,
	2024			2023			$ Change		% Change
Cost of sales	$	306		$	48		$	258		538	%
Percent of total revenue		133	%		28	%

Cost of revenue was $0.3 million and less than $0.1 million, respectively, for the three months ended September 30, 2024 and 2023. The increase is primarily due to the cost of transmitters sold, as the initial sales of 2-watt PowerBridge transmitters that were shipped during the third quarter of 2024 were built in-house. We believe the cost of producing these transmitters will decrease in future quarters, as we utilize a contract manufacturer more often. During the same period in 2023, revenue generated by transmitter sales represented a small percentage of the total revenue for that period, as the revenue for the three months ended September 30, 2023 consisted mainly of non-recurring engineering fees for which the cost was included in research and development costs.

Research and Development Costs:


	Three months ended September 30,
	2024			2023			$ Change		% Change
Research and development	$	1,701		$	2,460		$	(759)		(31)	%
Percent of total revenue		740	%		1,456	%

Research and development costs were $1.7 million and $2.5 million, respectively, for the three months ended September 30, 2024 and 2023. The decrease of $0.8 million is primarily due to a $0.3 million decrease in personnel-related expenses, consisting of a $0.2 million decrease in payroll costs and a $0.1 million decrease in stock-based compensation, a $0.2 million decrease in software costs, a $0.1 million decrease in engineering components and circuit boards, and a $0.1 million decrease in miscellaneous office and facility expenses.

Sales and Marketing Costs:


	Three months ended September 30,

Sales and marketing	$	699		$	774		$	(75)	(10)	%
Percent of total revenue		304	%		458	%

Sales and marketing costs for the three months ended September 30, 2024 and 2023 were $0.7 million and $0.8 million, respectively. The decrease of $0.1 million is primarily due to a $0.1 million decrease in personnel related costs due to reduced headcount.

General and Administrative Expenses:


	Three months ended September 30,

Other income resulting from the change in fair value of the warrant liability was $0.2 million for the three months ended September 30, 2024 and $0.8 million for the three months ended September 30, 2023. The changes for both periods were due to a lower market value of our common stock.

Interest income for the three months ended September 30, 2024 was $10,000 as compared to interest income of $179,000 for the three months ended September 30, 2023. The decrease was due to a lower average cash balance in our savings account during the three months ended September 30, 2024 compared to the prior year period.

Net Loss. As a result of the above, net loss for the three months ended September 30, 2024 was $3.4 million as compared to $4.1 million for the three months ended September 30, 2023.

Table of Contents

Revenue. During the nine months ended September 30, 2024 and 2023, we recorded revenue of $0.3 million and $0.4 million, respectively. The decrease is due to a decrease in non-recurring engineering revenue. Revenue for the nine months ended September 30, 2024 consisted primarily of transmitter sales volume versus the majority of revenue being derived from non-recurring engineering fees and the sale of semiconductor chips during the same period in 2023. This shift in revenue focus represents the beginning of the Company’s transition from research and development to commercial production of its PowerBridge transmitters.

Costs and Expenses and Loss from Operations. Costs and expenses are made up of cost of revenue, research and development, sales and marketing, general and administrative and severance expense. Loss from operations for the nine months ended September 30, 2024 and 2023 were $14.9 million and $17.5 million, respectively.

Cost of Revenue:


	Nine months ended September 30,
	2024			2023			$ Change		% Change
Cost of sales	$	537		$	270		$	267	99	%
Percent of total revenue		158	%		70	%

Cost of revenue was $0.5 million and $0.3 million, respectively, for the nine months ended September 30, 2024 and 2023. The increase is primarily due to the cost of transmitters sold, as the initial sales of 2-watt PowerBridge transmitters that were shipped during the second and third quarter of 2024 were built in-house. We believe the cost of producing these transmitters will decrease in future quarters, as we utilize a contract manufacturer more often. During the same period in 2023, revenue generated by transmitter sales represented a small percentage of the total revenue for that period, as the revenue for the nine months ended September 30, 2023 consisted mainly of non-recurring engineering fees for which the cost was included in research and development costs.

Research and Development Costs:


	Nine months ended September 30,
	2024			2023			$ Change		% Change
Research and development	$	6,489		$	8,419		$	(1,930)	(23)	%
Percent of total revenue		1,909	%		2,198	%

Research and development costs were $6.5 million and $8.4 million, respectively, for the nine months ended September 30, 2024 and 2023. The decrease of $1.9 million is primarily due to a $1.2 million decrease in employee compensation, consisting primarily of a $0.9 million decrease in personnel-related expenses and a $0.4 million decrease in stock-based compensation, a $0.4 million decrease in software and maintenance costs, a $0.1 million decrease in test development costs, a $0.1 million decrease in consulting and third-party expenses and a $0.1 million decrease in travel and miscellaneous office expenses, partially offset by a $0.1 million increase in engineering components and circuit boards.

Sales and Marketing Costs:


	Nine months ended September 30,
	2024			2023			$ Change		% Change
Sales and marketing	$	2,391		$	3,074		$	(683)	(22)	%
Percent of total revenue		703	%		803	%

Sales and marketing costs for the nine months ended September 30, 2024 and 2023 were $2.4 million and $3.1 million, respectively. The decrease of $0.7 million is primarily due to a $0.7 million decrease in employee compensation, consisting of a $0.6 million decrease in personnel related expenses due to a lower headcount within the department and a $0.1 million decrease in stock-based compensation, a $0.1 million decrease in tradeshow expense and a $0.1 million decrease in software, travel and miscellaneous office expenses, partially offset by a $0.3 million increase in consulting fees.

Table of Contents

General and administrative costs for the nine months ended September 30, 2024 and 2023 were $4.4 million and $5.8 million, respectively. The decrease of $1.3 million is primarily due to a $0.4 million decrease in stock-based compensation, a $0.3 million decrease in insurance premiums, a $0.3 million decrease in consulting and third-party service fees, a $0.2 million decrease in legal fees, a $0.1 million decrease in computer software and support and a $0.1 million decrease in travel and miscellaneous office expenses, partially offset by a $0.2 million increase in public relations and annual meeting costs.

Severance Expense:


	Nine months ended September 30,
	2024			2023			$ Change		% Change
Severance expense	$	1,377		$	359		$	1,018	284	%
Percent of total revenue		405	%		94	%

Severance expense for the nine months ended September 30, 2024 and 2023 was $1.4 million and $0.4 million, respectively. The increase of $1.0 million is primarily due to the departure of the former CEO during 2024 for which $1.2 million in severance expense was recorded, partially offset by $0.3 million in severance expense recorded during 2023 due to the departure of the former CFO.

Total other (expense) income, net	$	628	$	2,741	$	(2,113)	(77)	%

Offering costs related to warrant liability were $0.6 million for the nine months ended September 30, 2023. We did not incur such cost during the nine months ended September 30, 2024.

Other income resulting from the change in fair value of the warrant liability was $0.4 million for the nine months ended September 30, 2024 and $2.7 million for the nine months ended September 30, 2023. The changes for both periods were due to a lower market value of our common stock

Interest income for the nine months ended September 30, 2024 was $0.2 million as compared to interest income of $0.6 million for the nine months ended September 30, 2023. The decrease was due to a lower average cash balance in our savings account during the nine months ended September 30, 2024 compared to the prior year period.

Net Loss. As a result of the above, net loss for the nine months ended September 30, 2024 was $14.3 million as compared to $14.8 million for the nine months ended September 30, 2023.

Liquidity and Capital Resources

During the nine months ended September 30, 2024 and 2023, we recorded revenue of $0.3 million and $0.4 million, respectively. We incurred net losses of $14.3 million and $14.8 million for the nine months ended September 30, 2024 and 2023, respectively. Net cash used in operating activities was $14.9 million and $15.9 million for the nine months ended September 30, 2024 and 2023, respectively. As of September 30, 2024, the Company had cash and cash equivalents of $1.5 million. We are currently meeting our liquidity requirements through the proceeds of securities offerings that raised net proceeds of $2.5 million during 2024.

Based on current operating levels, we will need to raise additional funds in the next 12 months by selling additional equity or incurring debt.

As we gain traction in the market with our new technology and continue to invest capital in transitioning and scaling the business from research and development of new technologies to commercial production, there can be no assurance that our available resources and revenue generated from our business operations will be sufficient to sustain our operations.

Table of Contents

Accordingly, we expect to pursue additional financing, which could include offerings of equity or debt securities, bank financings, commercial agreements with customers or strategic partners, and other alternatives, depending upon market conditions. There is no assurance that such financing will be available on terms that we would find acceptable, or at all. If we are unsuccessful in implementing this plan, we will be required to make further cost and expense reductions or modifications to our on-going and strategic plans.

February 2024 Equity Offering

On February 15, 2024, we entered into a securities purchase agreement with an institutional investor, providing for the issuance and sale by us, in a registered direct offering (the “February 2024 Offering”), of (i) 570,000 shares of our common stock, (ii) pre-funded warrants to purchase up to 450,409 shares of common stock, and (iii) warrants to purchase up to an aggregate of 1,020,409 shares of common stock. Each share of common stock and pre-funded warrant was offered and sold together with an accompanying warrant at a combined price of $1.96 per share of common stock or pre-funded warrant, as applicable. The pre-funded warrants were exercised at a price of $0.001 per share during April 2024. The other warrants to purchase 1,020,409 shares of common stock are still outstanding and have an exercise price of $1.84 per share. These warrants expire five years from the date of issuance. We received net proceeds of approximately $1.8 million from the February 2024 Offering, after deducting placement agent fees and estimated offering expenses.

2024 ATM Offering Program

On June 21, 2024, we entered into the At the Market Offering Agreement with H.C. Wainwright & Co., LLC, as sales agent, pursuant to which we may issue and sell of up to $3.45 million in shares of the Company’s common stock (the “ATM Program”). During both the three and nine months ended September 30, 2024, we sold 1,217,168 shares of common stock under the ATM Program, respectively, for net proceeds of approximately $0.7 million (net of $0.2 million in commissions and issuance costs).

As of September 30, 2024, the Company had remaining capacity to issue up to approximately $2.5 million of common stock under the ATM Program.

Agile Subordinated Loan Agreement

Effective October 1, 2024, we entered into a subordinated business loan agreement (the “Original Loan Agreement”) with Agile Capital Funding, LLC and Agile Lending, LLC (collectively, the “Lender”), which provided for an initial term loan of $525,000, with the ability to receive additional term loans of up to $1.6 million, subject to certain conditions (such loans, the “Term Loan”). Principal and interest on the initial term loan in the aggregate amount of $756,000 was to be repaid in weekly payments of $27,000 commencing on October 14, 2024 and fully repaid on or before the maturity date of April 21, 2025. The Term Loan would be expressly subordinated to our obligations on certain senior indebtedness as provided in the Original Loan Agreement. Effective only upon the occurrence and continuance of an event of default under the Loan Agreement, we would grant the Lender a security interest in certain collateral, excluding intellectual property, of Energous Corporation as set forth in the Original Loan Agreement.

Effective November 5, 2024, we entered into an amended subordinated business loan agreement with the Lender (the “Amended Loan Agreement”) to refinance the Term Loan. The Amended Loan Agreement provides for a new term loan of $997,000, with the ability to receive additional term loans of up to $1.6 million, subject to certain conditions (such new loans, the “New Term Loan”). Principal and interest on the initial new term loan in the aggregate amount of $1,415,740 is to be repaid in weekly payments of approximately $39,000 and fully repaid on or before the maturity date of July 17, 2025. The proceeds of the New Term Loan were used to repay in full the Term Loan described above, which had a balance of $648,000 on November 5, 2024, and the remaining proceeds will be used for working capital. The New Term Loan will be expressly subordinated to our obligations on certain senior indebtedness of the Company as provided in the Amended Loan Agreement. The Amended Loan Agreement replaces the Original Loan Agreement and otherwise contains substantially the same terms as the Original Loan Agreement.

Regulation A Offering

On October 11, 2024, we filed a Regulation A Offering Statement on Form 1-A with an offering of a maximum of 5,000,000 Units (the “Regulation A Offering”), with each Unit consisting of one share of Series A Convertible Preferred Stock and three common stock purchase warrants, two to each purchase one share of common stock at an exercise price of $1.50 per share and one to purchase one share of common stock at $2.00 per share, for an aggregate of 5,000,000 shares of Series A Convertible Preferred Stock (and 10,000,000 shares of common stock underlying the shares of Series A Convertible Preferred Stock) and warrants to purchase up to an aggregate of 10,000,000 shares of common stock at an exercise price of $1.50 per share and 5,000,000 shares of common stock at an
