Since the date of the Annual Report on Form 10-K for the year ended December 31, 2020, there have been no material changes to the Company’s significant accounting policies, except as disclosed in this note.

During the nine months ended September 30, 2021, the Company raised gross proceeds of $6,500,000 in connection with the sale of preferred stock, common stock and warrants, and raised proceeds of $5,206,716 in connection with the exercise of warrants to purchase common stock. During the nine months ended September 30, 2021, the Company repaid outstanding notes payable in the amount of $2,450,000. Subsequent to September 30, 2021, the Company received an aggregate of $6,500,000 in connection with the exercise of warrants. See Note 12 – Subsequent Events for additional details.

As of September 30, 2021, the Company had cash of $10,990,056 and working capital of $10,659,878. While the Company anticipates it will continue to incur operating losses and use cash in operating activities for the foreseeable future, the Company believes that its current working capital is sufficient in comparison to its anticipated cash usage for a period of at least twelve months subsequent to the filing date of these financial statements.

Financial instruments that potentially subject the Company to significant concentrations of credit risk consist primarily of cash, accounts receivable, revenue and accounts payable.

A significant portion of the Company’s cash is held at one major financial institution. The Company has not experienced any losses in such accounts. Cash held in US bank institutions is currently insured by the Federal Deposit Insurance Corporation (“FDIC”) up to $250,000 at each institution. There was an uninsured balance of $10,489,922 and $8,513,010 as of September 30, 2021 and December 31, 2020, respectively.

The Company had certain customers whose revenue individually represented 10% or more of the Company's total revenue, or whose accounts receivable balances individually represented 10% or more of the Company's total accounts receivable, as follows:

There is no assurance the Company will continue to receive significant revenues from any of these customers. Any reduction or delay in operating activity from any of the Company’s significant customers, or a delay or default in payment by any significant customer, or termination of agreements with significant customers, could materially harm the Company’s business and prospects. As a result of the Company’s significant customer concentrations, its gross profit and

results from operations could fluctuate significantly due to changes in political, environmental, or economic conditions, or the loss of, reduction of business from, or less favorable terms with any of the Company’s significant customers.

Vendor concentrations are as follows for the three and nine months ended September 30, 2021 and 2020:

Inventory is comprised of carbon fiber velvet ("CFV") thermal interface solutions and internal short circuit batteries, which are available for sale. Inventories are stated at the lower of cost or net realizable value. Cost is determined by the first-in, first-out method. The cost of inventory that is sold to third parties is included within cost of sales and the cost of inventory that is given as samples is included within operating expenses. The Company periodically reviews for slow-moving, excess or obsolete inventories. Products that are determined to be obsolete, if any, are written down to net realizable value. As of September 30, 2021 and December 31, 2020, the Company's inventory was comprised solely of finished goods.

The Company recognizes revenue in accordance with Accounting Standards Codification (“ASC”) Topic 606, “Revenue from Contracts with Customers” (“ASC 606”). The core principle of ASC 606 requires that an entity recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the company expects to be entitled in exchange for those goods or services. ASC 606 defines a five-step process to achieve this core principle and, in doing so, it is possible more judgment and estimates may be required within the revenue recognition process, including identifying performance obligations in the contract, estimating the amount of variable consideration to include in the transaction price and allocating the transaction price to each separate performance obligation.

The Company recognizes revenue primarily from the following different types of contracts:

●

Product sales – Revenue is recognized at the point in time that the product is transferred to the customer, which is generally at the time products leave the Company’s distribution center.

●

Contract services – Revenue is recognized at the point in time that the Company satisfies its performance obligation under the contract, which is generally at the time the services are fulfilled and/or accepted by the customer.

The following table summarizes the Company's revenue recognized during the three and nine months ended September 30, 2021 and 2020:


	For the Three Months Ended				For the Nine Months Ended
	September 30,				September 30,
	2021		2020		2021		2020
Product sales	$	600,921	$	136,849	$	1,356,530	$	235,979
Contract services		—		—		290,540		179,498
Total revenue	$	600,921	$	136,849	$	1,647,070	$	415,477

As of September 30, 2021 and December 31, 2020, the Company had $158,816 and $20,000 of deferred revenue, respectively, from contracts with customers. The contract liabilities represent payments received from customers for which the Company had not yet satisfied its performance obligation under the contract, or the customers have not officially accepted the goods or services provided under the contract. During the three and nine months ended September 30, 2021 and 2020, there was no revenue recognized from performance obligations satisfied (or partially satisfied) in previous periods.

As of September 30, 2021 and December 31, 2020, the Company had $62,908 and $31,212, respectively, of deferred labor costs, which is included in prepaid expenses and other current assets in the Company's condensed consolidated balance sheets. Deferred labor costs represent costs to fulfill the Company's contract service revenue. The Company will recognize the deferred labor costs as cost of revenues at the point in time that the Company satisfies its performance obligation under the respective contract, which is generally at the time the services are fulfilled and/or accepted by the customer.

Shipping and Handling Costs

Amounts billed to a customer in a sales transaction related to shipping and handling are recorded as revenue. Costs incurred for shipping and handling are included as cost of revenues on the accompanying condensed consolidated statements of operations.

Net Loss Per Common Share

Basic net loss per common share is computed by dividing net loss by the weighted average number of common shares outstanding during the period, less unvested issued restricted stock. Diluted net loss per common share is computed by dividing net loss by the weighted average number of common and dilutive common-equivalent shares outstanding during each period, if not antidilutive.

The following shares were excluded from the calculation of weighted average dilutive common shares because their inclusion would have been anti-dilutive:


	September 30,
	2021	2020
Series B Convertible Preferred Stock	—	698,600
Series C Convertible Preferred Stock	—	189,000
Unvested restricted stock	2,615,000	—
Market-based equity awards	3,000,000	—
Options	590,000	395,000
Warrants	5,202,878	210,025
Total	11,407,878	1,492,625

Reclassifications

Certain amounts in the prior period financial statements have been reclassified to conform to the current period presentation. These reclassifications had no effect on reported consolidated net loss.

Recently Adopted Accounting Pronouncements

In December 2019, the Financial Accounting Standards Board (the "FASB") issued ASU 2019-12, "Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes," which is intended to simplify various aspects related to accounting for income taxes. ASU 2019-12 removes certain exceptions to the general principles in Topic 740 and also clarifies and amends existing guidance to improve consistent application. The Company adopted ASU 2019-12 effective January 1, 2021 and its adoption did not have a material impact on the Company's condensed consolidated financial statements and related disclosures.

Recently Issued Accounting Pronouncements

In August 2020, the FASB issued ASU 2020-06, Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity. ASU 2020-06 simplifies the accounting for certain financial instruments with characteristics of liabilities and equity, including convertible instruments and contracts in an entity’s own equity. ASU 2020-06 requires entities to provide expanded disclosures about the terms and features of convertible instruments and amends certain guidance in ASC 260, Earnings per Share, relating to the computation of earnings per share for convertible instruments and contracts in an entity’s own equity. The guidance becomes effective for the Company on January 1, 2024, with early adoption permitted. The Company is currently evaluating the impact of this new standard on its condensed consolidated financial statements.

On May 3, 2021, the FASB issued ASU 2021-04, Earnings Per Share (Topic 260), Debt—Modifications and Extinguishments (Subtopic 470-50), Compensation—Stock Compensation (Topic 718), and Derivatives and Hedging—Contracts in Entity’s Own Equity (Subtopic 815-40): Issuer’s Accounting for Certain Modifications or Exchanges of Freestanding Equity-Classified Written Call Options. This new standard provides clarification and reduces diversity in an issuer’s accounting for modifications or exchanges of freestanding equity-classified written call options (such as warrants) that remain equity classified after modification or exchange. This standard is effective for fiscal years beginning after December 15, 2021, including interim periods within those fiscal years. Issuers should apply the new standard prospectively to modifications or exchanges occurring after the effective date of the new standard. Early adoption is permitted, including adoption in an interim period. If an issuer elects to early adopt the new standard in an interim period, the guidance should be applied as of the beginning of the fiscal year that includes that interim period. The Company does not expect this new standard to have a material impact on its financial statements.

Subsequent Events

The Company evaluates events that have occurred after the balance sheet date but before the financial statements are issued. Based upon the evaluation, the Company did not identify any recognized or non-recognized subsequent events that would have required adjustment or disclosure in the condensed consolidated financial statements, except as disclosed.
