Business Organization, Nature of Operations

Note 1 - Business Organization, Nature of Operations

Energous Corporation (the “Company”) was incorporated in Delaware on October 30, 2012. The Company has developed its WattUp® wireless power technology, consisting of proprietary semiconductor chipsets, software controls, hardware designs and antennas, that enables radio frequency (“RF”) based charging for electronic devices. The WattUp technology has a broad spectrum of capabilities, including near field wireless charging and at-a-distance wireless charging at various distances. The Company believes its proprietary WattUp technologies are well suited for many applications, including building and home automation, electronic shelf labels, industrial IoT sensors, surface and implanted medical devices, tracking devices, hearables, wearables, consumer electronics and public safety applications. Potential future applications include smartphones, commercial and industrial robotics, as well as automotive solutions and other devices with charging requirements that would otherwise require battery replacement or a wired power connection.

Liquidity and Management Plans

Note 2 – Liquidity and Management Plans

During the three and six months ended June 30, 2022, the Company recorded revenue of $232,971 and $448,932, respectively. During the three and six months ended June 30, 2021, the Company recorded revenue of $184,960 and $330,025, respectively. During the three and six months ended June 30, 2022, the Company recorded net losses of $7,017,749 and $14,170,467, respectively. During the three and six months ended June 30, 2021, the Company recorded net losses of $11,015,829 and $19,541,592, respectively. Net cash used in operating activities was $13,453,948 and $12,537,690 for the six months ended June 30, 2022 and 2021, respectively. The Company is currently meeting its liquidity requirements through the proceeds of securities offerings that raised net proceeds of $53,556,202 during 2020, and $27,043,751 during the fourth quarter of 2021, proceeds from contributions to the Company’s employee stock purchase plan (the “ESPP”), along with payments received from customers.

As of June 30, 2022, the Company had cash on hand of $35,669,685. The Company expects that cash on hand as of June 30, 2022, together with anticipated revenues, will be sufficient to fund the Company’s operations through August 2023.

Research and development of new technologies is by its nature unpredictable. Although the Company intends to continue its research and development activities, 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.

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.

Accounting Policies [Abstract]

Summary of Significant Accounting Policies

Note 3 – Summary of Significant Accounting Policies

Basis of Presentation

The accompanying financial statements are presented in U.S. dollars and 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”).

These unaudited condensed interim financial statements should be read in conjunction with the audited financial statements and notes thereto for the fiscal year ended December 31, 2021 included in the Company's Annual Report on Form 10-K for the fiscal year ended December 31, 2021, filed with the SEC on March 23, 2022. The accounting policies used in preparing these unaudited condensed interim financial statements are consistent with those described in the Company’s December 31, 2021 audited financial statements.

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.

Note 3 – Summary of Significant Accounting Policies, continued

The Company’s significant estimates and assumptions include the valuation of stock-based compensation instruments, recognition of revenue, inventory valuation, the useful lives of long-lived assets, 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 and Cash Equivalents

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.

Revenue Recognition

The Company follows Accounting Standards Codification (“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.

The Company’s revenue comes from 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 six months ended June 30, 2022, the Company recognized $232,971 and $448,932, respectively, in revenue. During the three and six months ended June 30, 2021, the Company recognized $184,960 and $330,025, 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. The Company records the expenses related to these product development projects in research and development expense, in the periods such expenses were incurred.

The Company records revenue associated with the sale of production-level systems at the point in time at which control over the product is transferred to the customer. The Company records the expense related to the sales of these systems as cost of revenue during the period that the product is transferred to the customer.

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.

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 $3,209,910 and $6,103,694 for the three months ended June 30, 2022 and 2021, respectively. The Company incurred research and development costs of $6,737,056 and $10,694,938 for the six months ended June 30, 2022 and 2021, respectively.

Note 3 – Summary of Significant Accounting Policies, continued

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 June 30, 2022, 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 and six months ended June 30, 2022 or 2021. The Company files income tax returns with the United States and California 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 restricted stock units (“RSUs”) and performance stock units (“PSUs”) and the enrollment of employees in the ESPP. The computation of diluted loss per share excludes potentially dilutive securities of 6,212,707 and 6,323,445 for the three months ended June 30, 2022 and 2021, respectively, and 6,212,707 and 6,323,445 for the six months ended June 30, 2022 and 2021, respectively because their inclusion would be anti-dilutive.

Potentially dilutive securities outlined in the table below have been excluded from the computation of diluted net loss per share because the effect of their inclusion would have been anti-dilutive.

	For the Three Months Ended June 30,				For the Six Months Ended June 30,
	2022		2021		2022		2021

Total potentially dilutive securities		6,212,707		6,323,445		6,212,707		6,323,445

The table above includes 1,618,123 warrants expiring on October 6, 2022, with an exercise price of $23.00 and 1,666,666 warrants expiring on March 1, 2024, with an exercise price of $10.00.

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.

Note 3 – Summary of Significant Accounting Policies, continued

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 4 – Commitments and Contingencies, Operating Leases for further discussion of the Company’s operating leases.

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 7,500 shares may be purchased by an employee under the ESPP during an offering period. An offering period shall be six months in duration commencing on or about January 1 and July 1 of each year. The exercise price of the option will be 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 June 30, 2022, 353,751 shares of common stock remain eligible to be issued under the ESPP. Employees contributed $164,728 through payroll withholdings to the ESPP for the offering period ended June 30, 2022 and shares were be deemed delivered on that date.
