Summary of Significant Accounting Policies

Basis of Presentation

The accompanying financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America (“U.S. GAAP”). The accompanying financial statements have been prepared on a going concern basis, which contemplates the realization of assets and the settlement of liabilities and commitments in the normal course of business. The accompanying financial statements do not include any adjustment that might be necessary if the Company is unable to continue as a going concern. Certain reclassifications have been made to the prior year's balance sheet, statement of operations and statement of cash flows to conform to the current year presentation.

Going Concern Uncertainty

The accompanying financial statements have been prepared as if the Company will continue as a going concern. As noted above, the Company has experienced losses and negative cash flows from operations; incurred a net loss of$8.2 million during the year ended December 31, 2023; had cash and cash equivalents of$3.4 million as of December 31, 2023; and had an accumulated deficit of$37.9 million as of December 31, 2023. The Company's working capital as of December 31, 2023 was approximately$3.3 million. The aforementioned factors raise substantial doubt about the Company’s ability to continue as a going concern within one year from the issuance date of the financial statements. The accompanying financial statements have been prepared on a going concern basis, which contemplates the realization of assets and the satisfaction of liabilities in the normal course of business. The financial statements do not include any adjustments relating to the recoverability and classification of asset amounts or the classification of liabilities that might be necessary should the Company be unable to continue as a going concern within one year after the date the financial statements are issued.

Future capital requirements will depend upon many factors, including, without limitation, progress with developing, manufacturing and marketing our technologies; the time and costs involved in preparing, filing, prosecuting, maintaining and enforcing patent claims and other proprietary rights; our ability to establish collaborative arrangements; completion of any acquisitions or other strategic transactions; marketing activities and competing technological and market developments, including regulatory changes and overall economic conditions in our target markets. Our ability to generate revenue and achieve profitability requires us to successfully market and secure purchase orders for our products and services from existing as well as new customers. We also will be required to efficiently manufacture and deliver on those purchase orders. These activities, including our planned research and development efforts, may require significant uses of working capital. There can be no assurance that we will generate revenue and cash as expected in our current business plan.

The Company recognizes it will need to raise additional capital to continue research and development and to fund its planned operations, clinical trials and, if regulatory approval is obtained, commercialization of future products. We may seek additional funds through equity or debt offerings and/or borrowings under notes payable, lines of credit or other sources. We do not know whether additional financing will be available on commercially acceptable terms, or at all, when needed. If adequate funds are not available or are not available on commercially acceptable terms, our ability to fund our operations, support the growth of our business or otherwise respond to competitive pressures could be significantly delayed or limited, which could materially adversely affect our business, financial conditions, or results of operations.

Reverse Stock Split

In August 2023, the Company’s Board of Directors and stockholders approved an amendment to the Company’s amended and restated certificate of incorporation to effect a 1-for-100 reverse stock split of the issued and outstanding shares of the Company’s common stock, which was effected on August 23, 2023. There was no change to the par value, or authorized shares, of either the common stock or preferred stock, as a result of the reverse stock split. Fractional shares werenot issued, and instead, the Company issuedone whole share of the post reverse split common stock to any stockholder who otherwise would have been entitled to receive a fractional share as a result of the reverse stock split. Consequently,84 shares of common stock were issued in lieu of fractional shares. In addition, all options, warrants and other convertible securities of the Company outstanding immediately prior to the reverse stock split were adjusted by dividing the number of shares of common stock into which such options, warrants and other convertible securities were exercisable or convertible by 100 and multiplying the exercise or conversion price thereof by 100, all in accordance with the terms of the plans, agreements or arrangements governing such options, warrants and other convertible securities and subject to rounding pursuant to such terms. All share and per share amounts for the common stock, as well as the stock options, and warrants outstanding and exercise prices thereof, included in the financial statements and these footnotes thereto have been retroactively restated to give effect to the reverse stock split.

Use of Estimates

The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and reported amounts of expenses during the reporting period. Actual results could differ materially from those estimates. The Company evaluates its estimates and assumptions on an ongoing basis using historical experience and other factors and adjusts those estimates and assumptions when facts and circumstances dictate.

Fair Value of Financial Instruments

The Company discloses and recognizes the fair value of its assets and liabilities using a hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability (an exit price) in an orderly transaction between market participants at the reporting date. The hierarchy gives the highest priority to valuations based upon unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to valuations based upon unobservable inputs that are significant to the valuation (Level 3 measurements). The guidance establishes three levels of the fair value hierarchy as follows:

Level 1 Inputs that reflect unadjusted quoted prices in active markets for identical assets or liabilities that the Company has the ability to access at the measurement date;

Level 2 Inputs other than quoted prices that are observable for the asset or liability either directly or indirectly, including inputs in markets that are not considered to be active;

Level 3 Inputs are unobservable in which there is little or no market data available, which require the reporting entity to develop its own assumptions that are unobservable.

Assets and liabilities measured at fair value are classified in their entirety based on the lowest level of input that is significant to the fair value measurement. The Company’s assessment of the significance of a particular input to the fair value measurement in its entirety requires management to make judgments and consider factors specific to the asset or liability.

Cash and Cash Equivalents

The Company considers all highly liquid investments with original maturities of three months or less at date of purchase to be cash equivalents. As of December 31, 2023 and 2022, cash equivalents were$3.2 million and$3.1 million, respectively.

Accounts Receivable

Trade accounts receivable are recorded at the invoiced amount, net of allowances for doubtful accounts. The allowance for doubtful accounts is based on our assessment of the collectability of accounts. Management regularly reviews the adequacy of the allowance for doubtful accounts by considering the age of each outstanding invoice, each customer’s expected ability to pay, and the collection history with each customer, when applicable, to determine whether a specific allowance is appropriate. Accounts receivable deemed uncollectible are charged against the allowance for doubtful accounts when identified. As of each December 31, 2023 and 2022, the allowance for doubtful accounts waszero.

Inventory

Inventories are stated at the lower of cost or net realizable value, with cost determined on a first-in, first-out ("FIFO") basis. Inventories are reviewed periodically to identify slow-moving inventory based on anticipated sales activity. As of December 31, 2023 and 2022, the reserve for obsolescence was $32,000 andzero, respectively.

Deferred Offering Costs

Deferred offering costs are comprised of costs incurred in connection with financing arrangements that have not closed as of the end of the period. As of December 31, 2022, deferred offering costs of $584 thousand, primarily consisted of legal fees, technical accounting support, printer costs and other regulatory filing fees related to the sale of 200,000 shares of our common stock, which closed subsequent to year-end. Deferred offering costs are reclassified to additional paid in capital upon closing of the financing transaction. There wereno deferred offering costs as of December 31, 2023.

Property and Equipment

Property and equipment are recorded at cost net of accumulated depreciation. Depreciation is computed on a straight-line method over the estimated useful lives of the assets, three tofour years. Upon retirement or sale of assets, the cost and related accumulated depreciation are removed from the balance sheet and the resulting gain or loss is reflected in operations. Repairs and maintenance costs that do not improve or extend the lives of the respective assets are charged to operations as incurred.

Impairment of Long-Lived Assets

The Company evaluates its long-lived assets, including property and equipment, for impairment whenever events or changes in circumstances indicate that the carrying amount of these asset may not be recoverable. Recoverability of these assets is measured by comparison of the carrying amount of each asset to the future undiscounted cash flows the asset is expected to generate over its remaining life. When indications of impairment are present and the estimated undiscounted future cash flows from the use of these assets is less than the assets’ carrying value, the related assets will be written down to fair value. There wereno impairments of the Company’s long-lived assets for the periods presented.

Commitments and Contingencies

Liabilities for loss contingencies arising from claims, assessments, litigation, fines, and penalties and other sources are recorded when it is probable that a liability has been incurred and the amount can be reasonably estimated. Legal costs incurred in connection with loss contingencies are expensed as incurred.

Revenue Recognition

The Company recognizes revenue from product sales in accordance with Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) Topic 606, Revenue from Contracts with Customers (“Topic 606”). The adoption of this guidance did not have a material impact on the Company’s financial statements. The standard applies to all contracts with customers, except contracts that are within scope of other standards, such as leases, insurance, collaboration arrangements and financial instruments.

Under Topic 606, an entity recognizes revenue when its customer obtains control of promised goods or services, in an amount that reflects the consideration that the entity expects to receive in exchange for those goods or services. To determine revenue recognition for arrangements that an entity determines are in within the scope of Topic 606, the entity performs the following five steps: (i) identify the contract(s) with a customer; (ii) identify the performance obligations in the contract; (iii) determine the transaction price; (iv) allocate the transaction price to the performance obligations in the contract; and (v) recognize revenue when (or as) the entity satisfies a performance obligation. The Company only applies the five-step model to contracts when it is probable the entity will collect the consideration it is entitled to in exchange for the goods or services it transfers to the customer. At contract inceptions, once the contract is determined to be within the scope of Topic 606, the Company assesses the goods or services promised within each contract and determines those that are performance obligations and assesses whether each promised good or service is distinct. The Company then recognizes as revenue the amount of the transaction price that is allocated to the respective performance obligation when (or as) the performance obligation is satisfied.

The Company sells its products through direct sales and reseller. Revenue is recognized when control of the promised goods is transferred to the customers or the resellers, upon shipment of the product, in an amount that reflects the consideration the Company expects to be entitled to in exchange for those goods. Revenue associated with products holding rights of return are recognized when the Company concludes there is not a risk of significant revenue reversal in the future periods for the expected consideration in the transaction.

The Company may receive payments at the onset of the contract and before goods have been delivered. In such instances, the Company records a deferred revenue liability. The Company recognizes these contract liabilities as sales after the revenue criteria are met. As of December 31, 2023 and 2022, the contract liability related to the Company’s deferred revenues approximated$8 thousand and$2 thousand, respectively, and are included in “Other Accrued Expenses” on the accompanying balance sheets.

The Company relies on a third party to have procedures in place to detect and prevent credit card fraud as the Company has exposure to losses from fraudulent charges. The Company records the losses related to chargebacks as incurred.

The Company has also elected to exclude from the measurement of the transaction price sales taxes remitted to governmental authorities.

The table below presents revenue by channel for the years ended December 31, 2023 and 2022 (in thousands):

Sales Tax

Sales tax collected from customers and remitted to governmental authorities is accounted for on a net basis and therefore, is excluded from net sales.

Shipping and Handling

Shipping and handling fees paid by customers are recorded within net sales, with the related expenses recorded in cost of sales. Shipping and handling fees paid by customers in each of the years ended December 31, 2023 and 2022 were$3 thousand. Shipping costs for delivery of product to customers in the years ended December 31, 2023 and 2022 were$59 thousand and$96 thousand, respectively.

Product Warranty

The Company generally offers aone-year limited warranty on its products. The Company estimates the costs associated with the warranty obligation using historical data of warranty claims and costs incurred to satisfy those claims. Estimated warranty costs are expensed to cost of sales.

Returns

The Company estimates a reserve for future product returns based several factors, including historical returns as a percentage of revenue, an understanding of the reasons for past returns and any other known factors that indicate a return is imminent. Reserves for sales returns are estimated and recorded in the same period as the underlying revenue recognition as a deduction to arrive at net product sales and as a liability classified as Other accrued expenses on the balance sheet. As of December 31, 2023 and 2022, the reserve for sales returns was$52 thousand and$19 thousand, respectively.

Sales and marketing expenses are expensed as incurred and consist primarily of merchandising, customer service and targeted online marketing costs, such as display advertising, keyword search campaigns, search engine optimization and social media and offline marketing costs such as television, radio and print advertising. Sales and marketing expenses also include payroll costs and stock-based compensation expense for employees involved in marketing activities. Sales and marketing expenses are primarily related to growing and retaining the customer base. Advertising and other promotional costs to market the Company’s products and services amounted to$822 thousand and$1.3 million for the years ended December 31, 2023 and 2022, respectively.

Research and development expenses include costs directly attributable to the conduct of research and development programs, including the cost of salaries, payroll taxes, employee benefits, materials, supplies, depreciation on and maintenance of research equipment, the cost of services provided by outside contractors, and the allocable portions of facility costs, such as rent, utilities, insurance, repairs and maintenance, depreciation, and general support services. All costs associated with research and development are expensed as incurred.

The Company accounts for stock-based compensation arrangements with employees and non-employee consultants using a fair value method which requires the recognition of compensation expense for costs related to all stock-based payments, including stock options. The fair value method requires the Company to estimate the fair value of stock-based payment awards to employees and non-employees on the date of grant using an option pricing model.

Stock-based compensation costs are based on the fair value of the underlying option calculated using the Black-Scholes option-pricing model and recognized as expense on a straight-line basis over the requisite service period, which is the vesting period. The Company measures equity-based compensation awards granted to non-employees at fair value as the awards vest and recognizes the resulting value as compensation expense at each financial reporting period.

Determining the appropriate fair value model and related assumptions requires judgment, including estimating stock price volatility, expected dividend yield, expected term, risk-free rate of return, and the estimated fair value of the underlying common stock. Due to the lack of company-specific historical and implied volatility data, the Company has based its estimate of expected volatility on the historical volatility of a group of similar companies that are publicly traded. The historical volatility is calculated based on a period of time commensurate with the expected term assumption. The group of representative companies have characteristics similar to the Company, including stage of product development and focus on the life science industry. The Company uses the simplified method, which is the average of the final vesting tranche date and the contractual term, to calculate the expected term for options granted to employees as it does not have sufficient historical exercise data to provide a reasonable basis upon which to estimate the expected term. The risk-free interest rate is based on a treasury instrument whose term is consistent with the expected term of the stock options. The Company uses an assumed dividend yield ofzero as the Company has never paid dividends and has no current plans to pay any dividends on its common stock. The Company accounts for forfeitures as they occur.

Segment Reporting

Operating segments are identified as components of an enterprise for which separate discrete financial information is available for evaluation by the Company’s Chief Executive Officer to make decisions with respect to resource allocation and assessment of performance. To date, the Company has viewed its operations and manages its business asone operating segment.

Net Loss per Common Share

The Company computes net loss per share of common stock in conformity with the two-class method required for participating securities. Diluted net loss per share is computed similar to basic net loss per share except that the denominator is increased to include the number of additional shares for the potential dilutive effects of warrants, convertible preferred stock and stock options outstanding during the period calculated in accordance with the treasury stock method, or the two-class method, whichever is more dilutive. For all periods presented, basic and diluted net loss per share is the same, as inclusion of any additional share equivalents would be anti-dilutive.

Income Taxes

Income taxes are accounted for under the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases and operating loss and tax credit carry forwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. Valuation allowances are established when necessary to reduce deferred taxes to the amounts expected to be realized.

The Company recognizes benefits of uncertain tax positions if it is more likely than not that such positions will be sustained upon examination based solely on their technical merit, as the largest amount of benefit that is more likely than not to be realized upon the ultimate settlement. The Company’s policy is to recognize interest and penalties related to the underpayment of income taxes as a component of income tax expense or benefit. To date, there have beenno interest or penalties charged in relation to the unrecognized tax benefits.

Concentration of Credit Risk and Other Risks and Uncertainties

Financial instruments that potentially subject the Company to significant concentrations of credit risk consist of cash and cash equivalents and accounts receivable. Cash and cash equivalents include a checking account and a money market account held at one national financial institution in the United States. At times, such deposits may be in excess of insured limits. Despite recent concerns regarding the stability of certain banking institutions in the United States, management believes that the financial institution at which the Company holds its deposits is financially sound, and accordingly, minimal credit risk exists with respect to the financial institution. The Company has not experienced any losses on its deposits of cash and cash equivalents. As of each December 31, 2023 and 2022, the Company had cash and cash equivalents balances exceeding FDIC insured limits by$3.0 million.

The Company extends credit to customers in the normal course of business and performs credit evaluations of its customers. Concentrations of credit risk with respect to accounts receivable exist to the full extent of amounts presented in the financial statements.

During 2023, the majority, or 79%, of the Company's sales have been to individual consumers. As of December 31,2023, the Company hadone customer whose accounts receivable balance totaled more than 10% or more of the Company’s total accounts receivable (81%) compared withtwo customers at December 31,2022 (43% and 18%).

For the year ended December 31, 2023, the Company hadone customer who individually accounted for 10% or more of the Company’s total revenue (20%) compared withone customer for the year ended December 31,2022 (20%).

The world has been affected by the COVID-19 pandemic, the ongoing conflict between Russia and Ukraine, economic uncertainty in human capital management and certain other macroeconomic factors including climate change, inflation, and rising interest rates. Additionally, events involving limited liquidity, defaults, non-performance or other adverse developments that affect financial institutions or the financial services industry generally, or concerns or rumors about any events of these kinds or other similar risks, have in the past and may in the future lead to market-wide liquidity problems. For example, in March 2023, Silicon Valley Bank and Signature Bank were closed and taken over by the FDIC, which created significant market disruption and uncertainty for those who bank with those institutions, and which raised significant concern regarding the stability of the banking system in the United States, and in particular with respect to regional banks. These factors, amongst other things, could result in further economic uncertainty and volatility in the capital markets in the near term, and could negatively affect our operations. We will continue to monitor material impacts on our business strategies and operating results.

Leases

At the inception of an arrangement, the Company determines whether the arrangement is or contains a lease based on the circumstances present. The Company accounts for a contract as a lease when it has the right to control the asset for a period of time while obtaining substantially all of the asset’s economic benefits. The Company determines the initial classification and measurement of its operating right-of-use (“ROU”) assets and operating lease liabilities at the lease commencement date, and thereafter if modified. The lease term includes any renewal options that the Company is reasonably assured to exercise. The Company’s policy is to not record leases with a lease term of 12 months or less on its balance sheets. The Company’s only existing lease is for office space.

The ROU asset represents the right to use the leased asset for the lease term. The lease liability represents the present value of the lease payments under the lease. The present value of lease payments is determined by using the interest rate implicit in the lease, if that rate is readily determinable; otherwise, the Company uses its estimated secured incremental borrowing rate for that lease term.

Lease expense for operating leases is recognized on a straight-line basis over the reasonably assured lease term based on the total lease payments and is included in operating expense in the statement of operations.

The Company's facility lease contracts often include lease and non-lease components. The Company has elected the practical expedient offered by the standard to not separate lease from non-lease components and accounts for them as a single lease component.

The Company has elected, for all classes of underlying assets, not to recognize ROU assets and lease liabilities for leases with a term of twelve months or less. Lease cost for short-term leases is recognized on a straight-line basis over the lease term.

Recently issued accounting pronouncement - Not yet adopted:

In November 2023, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update (ASU) 2023-07, Segment Reporting (Topic 280) -Improvements to Reportable Segment Disclosures. The guidance, which becomes effective for fiscal years beginning after December 15, 2023 and interim periods within fiscal years beginning after December 15, 2024, requires public entities that are required to report segment information in accordance with Topic 280, Segment Reporting, to improve reportable segment disclosures about significant segment expenses. We do not believe that ASU 2023-07 will have a material impact on our reporting as we operate in one reportable segment.

In December 2023, the FASB issued Accounting Standards Update (ASU) 2023-09, Income Taxes (Topic 740)-Improvements to Income Tax Disclosures. The guidance applies to all entities that are subject to Topic 740, Income taxes and becomes effective for public business entities for annual periods beginning after December 15, 2024. The guidance requires enhanced disclosures related to income taxes including: additional information in the rate reconciliation; further breakdown of income taxes paid; and other disclosures that may help investors to better understand the entities tax landscape. We do not believe that ASU 2023-09 will have a material impact on our financial reporting.

Financial Instruments and Fair Value Measurements

The Company’s financial instruments consist of money market funds. The following tables show the Company’s cash equivalent's carrying value and fair value at December 31,2023 and 2022 (in thousands):

Cash equivalents – Cash equivalents of$3.2 million and$3.1 million as of December 31, 2023 and 2022, respectively, consisted of money market funds. Money market funds are classified as Level 1 of the fair value hierarchy because they are valued using quoted market prices in active markets.

Certain assets and liabilities are carried at fair value under GAAP. Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. Valuation techniques used to measure fair value must maximize the use of observable inputs and minimize the use of unobservable inputs.

There have been no changes to the valuation methods utilized by the Company during the years ended December 31, 2023 and 2022. The Company evaluates transfers between levels at the end of each reporting period. There wereno transfers of financial instruments between levels during the years ended December 31,2023 and 2022.

Commitments and Contingencies

Lease

The Company executed a noncancelable operating lease for approximately 9,091 square feet of office space in Hayward, California in November 2021 as its headquarters. The lease expires in October 2025 and there isno option to renew for an additional term. The Company is obligated to pay, on a pro-rata basis, real estate taxes and operating costs related to the premises. Upon lease execution, the Company evaluated the lease and determined it should be capitalized as an operating lease. As there was no interest rate implicit in the lease, the Company estimated the incremental borrowing rate at 6% based on the rate available under its revolving credit line, as well as an assessment of the Company's risk based on its financial position at the time and its potential to obtain a collateralized loan for a period similar to the lease term.

The lease costs for the years ended December 31,2023 and 2022 are as follows (in thousands):

Additionally, as partial consideration for services rendered in connection with the offering, the Company issued the placement agent unregistered warrants to purchase an aggregate of 13,270 shares of Company common stock, representing 4.0% of the aggregate shares sold in the offering. The warrants have an initial exercise price of $4.92 per share (equal to 120% of the offering price per share), have a term offive years from the commencement of sales in the offering, and are exercisable commencingsix months from closing.

Effective August 23, 2023, the Company's board of directors approved a reverse stock split of the Company's issued and outstanding shares of common stock, par value $0.0001 per share, at a ratio of 1-for-100. As a result of the reverse stock split, the total number of shares of common stock held by each stockholder of the Company were converted automatically into the number of shares of common stock equal to the number of issued and outstanding shares of common stock held by each such stockholder immediately prior to the reverse stock split divided by 100. The Company issuedone whole share of the post reverse stock split common stock to any stockholder who otherwise would have been entitled to receive a fractional share as a result of the reverse stock split. As a result, no fractional shares were issued in connection with the reverse stock split andno cash or other consideration was paid in connection with any fractional shares that would otherwise have resulted from the reverse stock split. Also, all options, warrants and other convertible securities of the Company outstanding immediately prior to the reverse stock split were adjusted by dividing the number of shares of common stock into which such options, warrants and other convertible securities were exercisable or convertible by 100 and multiplying the exercise or conversion price thereof by 100, all in accordance with the terms of the plans, agreements or arrangements governing such options, warrants and other convertible securities and subject to rounding pursuant to such terms. There was no change to the par value, or authorized shares, of either the common stock or preferred stock, as a result of the reverse stock split. All share and per share amounts for the common stock, as well as the warrants outstanding and exercise prices thereof, have been retroactively restated to give effect to the reverse stock split.

Common stockholders are entitled to dividends if and when declared by the Board of Directors subject to the rights of the preferred stockholders. As of December 31,2023, no dividends on common stock had been declared by the Company. At December 31,2023 and 2022, the Company had reserved shares of common stock for issuance as follows:

Common Stock Warrants

Historically, the Company has entered into warrant agreements in connection with certain consulting agreements and equity offerings. In August 2023, the Company implemented a 1-for-100 reverse stock split wherein, per the terms of the agreements, the number of shares of common stock issuable upon exercise of each of the warrants outstanding at that time was reduced by dividing the quantity outstanding by 100 and the exercise price of each such warrant was multiplied by 100. No other terms of the warrants were changed as a result of the reverse stock split.

In July 2021, the Company entered into a consulting agreement, pursuant to which 500 warrants to purchase common stock were granted and an additional 500 warrants to purchase common stock were granted in November 2021. The warrants are exercisable upon issuance, have an exercise price of $104 per share and have a term offive years. The consulting agreement was effective as of February 2021, had an initial monthly fee of $5 thousand and a term oftwo years. The agreement was amended in May of 2022 to increase the monthly payment to $7.5 thousand. Currently, the agreement is automatically renewing on a month-to-month basis until terminated by either party. The warrant issuances are indexed to, and settled in, the Company’s own common stock and were classified within stockholders’ equity.

In November 2021, the Company issued warrants to purchase 1,727 shares of common stock to designees of ThinkEquity LLC (“ThinkEquity”), the underwriter of the IPO. The warrants may be exercised at any time on or after May 9, 2022, have an exercise price of $625 per share and have a term offive years. The warrant issuances are indexed to and settled in the Company’s own common stock and were classified within stockholders’ equity.

In February 2023, the Company issued warrants to purchase 10,000 shares of common stock to designees of ThinkEquity, the underwriter of the underwritten public offering of 200,000 shares of Company common stock that closed in February 2023. The designees paid an aggregate of $0.1 thousand for the warrants. The warrants may be exercised at any time on or after August 7, 2023, have an exercise price of $31.25 per share, and have a term offour years commencing 180 days following the commencement of sales in the offering. The warrant issuances were indexed to and settled in the Company’s own stock and were classified within stockholders’ equity.

In July and August 2023, the Company issued a total of 47,670 warrants to purchase shares of common stock to Maxim Group, LLC ("Maxim"), the placement agent for each of the three public offerings of the Company's common stock completed during the period. The warrants are exercisable at any time beginningsix months after the close of the applicable equity offering and expire five years from the from the commencement of sales under the applicable offering. Of the warrants issued in the offerings,13,000 are exercisable beginning on January 11, 2024 at a price of $6.60 per share;20,500 are exercisable beginning on January 19, 2024 at a price of $4.80 per share; and 13,270 are exercisable beginning on February 9, 2024 at a price of $4.92 per share.

The Company estimated the value of the warrants in 2023 using the Black-Scholes options valuation model. The fair value of the warrants issued in February 2023 was $195 thousand and was recognized as issuance costs of the common stock issued in the underwritten public offering and was classified within stockholders' equity. The fair value of the warrants issued in July and August 2023 totaled $168 thousand and was recognized as issuance costs of the common stock issued in the three offerings during the period and was classified within stockholders' equity.

The fair value of the warrants issued in 2023 was estimated on the date of grant using the following assumptions:

A summary of the Company’s outstanding warrants as of December 31,2023 is as follows:

Equity Incentive Plans

In 2017, the Company adopted the 2017 Equity Incentive Plan (the “2017 Plan”).

On November 10, 2021, the 2017 Plan terminated and was replaced by the 2021 Plan (defined below), and future issuances of incentive instruments will be governed by the 2021 Plan. To the extent that outstanding awards under the 2017 Plan are forfeited or lapse unexercised, the shares of common stock subject to such awards will no longer be available for future issuance.

2021 Equity Incentive Plan

In 2021, the Company adopted the 2021 Equity Incentive Plan (the “2021 Plan”). Options granted under the 2021 Plan may be Incentive Stock Options or Non-statutory Stock Options, as determined by the Compensation Committee of the Company’s board of directors, who is responsible for administering the 2021 Plan. Stock Purchase Rights may also be granted under the 2021 Plan. The term shall be no more thanten years from the date of grant thereof. In the case of an Incentive Stock Option granted to an optionee who, at the time the option is granted, owns stock representing more than 10% of the voting power of all classes of stock of the Company or any Parent or Subsidiary, the term of the option shall befive years from the date of grant or such shorter term as may be provided in the option Agreement. To the extent outstanding awards under the 2021 Plan are forfeited or lapse unexercised, the shares of common stock subject to such awards will be available for future issuance under the 2021 Plan. The 2021 Plan provides that additional shares will automatically be added to the shares authorized for issuance under the 2021 Plan on January 1 of each year. The number of shares added each year will be equal to the lesser of: (i)5.0% of the outstanding shares of the Company’s common stock on December 31st of the preceding calendar year or (ii) such number of shares determined by the board of directors, in its discretion. On January 1, 2023,4,839 shares were automatically added to the number of shares authorized for issuance under 2021 Plan (an increase equal to 5% of the number of the outstanding shares of Company common stock as of December 31, 2022. Subsequent to the year ended December 31, 2023, on January 1, 2024,73,304 shares were automatically added to the number of shares authorized for issuance under 2021 Plan (an increase equal to 5% of the number of the outstanding shares of Company common stock as of December 31, 2023).

In the case of an Incentive Stock Option, (i) granted to an employee who, at the time of grant of such option, owns stock representing more than 10% of the voting power of all classes of stock of the Company or any Parent or Subsidiary, the exercise price shall be no less than 110% of the Fair Market Value per Share on the date of grant; (ii) granted to any other employee, the per share exercise price shall be no less than 100% of the Fair Market Value per Share on the date of grant. In the case of a Non-statutory Stock Option, the per share exercise price shall be no less than 100% of the Fair Market Value per Share on the date of grant. Notwithstanding the foregoing, options may be granted with a per share exercise price other than as required above pursuant to a merger or other corporate transaction.

The options may include provisions permitting exercise of the option prior to full vesting. Any unvested shares upon termination shall be subject to repurchase by the Company at the original exercise price of the option. Stock options granted under the Company’s equity incentive plans generally vest over four years from the date of grant.

As of December 31, 2023, there were 7,190 shares of common stock available for issuance under the 2021 Plan.

The following table summarizes the option activity for the years ended December 31,2023 and 2022:

The weighted-average grant date fair value per share of stock options granted in 2023 and 2022 was $0.12 and $1.01, respectively. The aggregate intrinsic value of options vested and exercisable as of December 31,2023 is calculated based on the difference between the exercise price and the current fair value of our common stock. As of December 31, 2023 there were no options outstanding or vested with an exercise price in excess of the market price of our stock.

The following table sets forth the status of the Company’s non-vested restricted common stock awards issued to employees:

The fair value of restricted stock awards vested during the year ended December 31, 2022 was $11 thousand. There wereno restricted stock awards outstanding during the year ended December 31, 2023.

Options generally vest over four years whereby 25% vest upon the first anniversary of the issuance date and 1/36th per month thereafter. Stock-based compensation expense recognized during the years ended December 31,2023 and 2022 was$271 thousand and$398 thousand, respectively. As of December 31, 2023, there were total unrecognized compensation costs of$440 thousand related to share-based payment awards which is expected to be recognized over a weighted-average amortization period of 2.04 years.

Prior to the IPO, the grant date fair market value of the shares of common stock underlying stock options had historically been determined by the Company’s Board of Directors. Because there had been no public market for the Company’s common stock, the Board of Directors exercised reasonable judgment and considered a number of objective and subjective factors to determine the best estimate of the fair market value, which included valuations performed by an independent third-party, important developments in the Company's operations, sales of the Company’s convertible preferred stock, actual operating results, financial performance, the conditions in the life sciences industry, the economy in general, the stock price performance and volatility of comparable public companies, and the lack of liquidity of the Company's common stock. For 2022 and 2023, the Company has used a comparative peer group for determining the expected volatility rate used in the calculation of fair value. Since the Company's stock has not been publicly traded for a sufficiently long period of time, the expected volatility rate is based on a review of the historical volatilities, over a period of time equivalent to the expected life of the instrument being valued, of similarly positioned public companies within the Company's industry.

The Company estimated the fair value of share-based payment awards using the Black-Scholes options valuation model. The fair value of share-based payment awards is being amortized on a straight-line basis over the requisite service period of the awards. The fair value of share-based payment awards was estimated on the date of grant using the following assumptions:

Expected Term: The Company uses the simplified method to calculate expected term described in the Securities and Exchange Commission’s Staff Accounting Bulletin No. 107, which takes into account vesting term and expiration date of the options.

Volatility: Volatility is based on an average of the historical volatilities of comparable publicly traded companies for the expected term.

Risk Free Interest Rate: The risk-free rate is based on the U.S. Treasury yields in effect at the time of grant for periods corresponding with the expected term of the option.

Dividend Yield: The Company has never declared or paid any cash dividends and does not plan to pay cash dividends in the foreseeable future, and therefore, used an expected dividend yield of zero in the valuation model.

No income tax benefits have been recognized relating to stock-based compensation expenses andno tax benefits have been realized from exercised stock options.

Total Stock-Based Compensation

Total stock-based compensation expense recorded related to share-based payment awards was allocated to research and development, sales and marketing, and general and administrative expense as follows (in thousands):

Income Taxes

The provision for income taxes differs from the amount which would result by applying the federal statutory income tax rate to pre-tax loss for the years ended December 31, 2023 and 2022.

A reconciliation of the provision computed at the federal statutory rate to the provision for income taxes included in the accompanying statements of operations for the Company is as follows.

For the years ended December 31, 2023 and 2022, the Company’s effective tax rate is below the federal statutory income tax rate of 21% primarily due to state income taxes, net of federal benefit and the Company’s position to establish a full valuation allowance on its deferred tax assets.

The tax effects of temporary differences and carryforwards that give rise to significant portions of the net deferred tax assets are presented below (in thousands):

The Company has recorded a valuation allowance for its deferred tax assets that it does not believe will be realizable at a more likely than not level based on analysis of all available sources of taxable income. The valuation allowance increased by$354 thousandand $2.9 million for the years ended December 31,2023 and 2022, respectively, due to current and previous year losses and credits claimed.

At December 31, 2023 and 2022, the Company had federal net operating loss carryforwards of approximately$30.4 million and $23.3 million, respectively, which will begin to expire in 2036. Approximately $29.9 million of federal net operating losses can be carried forward indefinitely. At December 31,2023 and 2022, the Company had state net operating loss carryforwards for California of approximately$5.1 millionand $23.2 million, respectively, which will begin to expire in 2031. The Company also had federal and state research and development credit carryforwards of approximately $31 thousand and $296 thousand, respectively, at December 31, 2023. The federal credits start to expire in 2043. The California credits carryforward indefinitely.

Federal and state tax laws impose substantial restrictions on the utilization of net operating loss and credit carryforwards in the event of an “ownership change” for tax purposes, as defined in Section 382 of the Internal Revenue code. Accordingly, the Company’s ability to utilize these carryforwards may be limited as a result of such ownership changes. Such a limitation could result in limitation in the use of net operating losses in future years and possibly a reduction of the net operating losses available. The Company has not performed a 382 study to determine if any ownership changes have occurred which could potentially limit the utilization of the tax attribute carryforwards.

A reconciliation of the beginning and ending amount of gross unrecognized tax positions is as follows (in thousands):

During the year ended December 31, 2023 the amount of unrecognized tax benefits decreased by $17 thousand due to current year research and development credits generated during the year offset by a reduction in research and development credits available for use due to application of the Section 382 limitations. During the year ended December 31, 2022 the amount of unrecognized tax benefits increased by $62 thousand due to additional research and development credits generated during the year. As of December 31,2023 and 2022, the total amount of unrecognized tax benefits was $98 thousand and $115 thousand, respectively. The reversal of the uncertain tax benefits would not affect the Company’s effective tax rate to the extent that it continues to maintain a full valuation allowance against its deferred tax assets.

The Company recognizes interest and penalties related to unrecognized tax benefits in the provision for income taxes line item in the statements of operations. As of December 31, 2023, and 2022, the Company hadnot accrued any interest or penalties related to uncertain tax positions. The Company does not anticipate any material change in its unrecognized tax benefits over the next twelve months. The unrecognized tax benefits may change during the next year for items that arise in the ordinary course of business.

The Company files tax returns in U.S. Federal and state jurisdictions. The tax periods from 2016 to 2023 remain open to examination in all jurisdictions. In addition, any tax losses that were generated in prior years and carried forward may also be subject to examination by the respective authorities. The Company is not currently under examination by income tax authorities for federal or state purposes.

Net Loss per Share

The following outstanding potentially dilutive common stock equivalents have been excluded from the calculation of diluted net loss per share for the periods presented due to their antidilutive effect:

Related Party Transactions

In December 2021, the Company entered into an agreement with a significant shareholder for certain product development consultation services. During the years ended December 31, 2023 and 2022, the Company incurred $14 thousand and $18 thousand, respectively, of expenses in connection with the agreement. The expenses are included in research and development expense. There wereno unpaid balances due to the shareholder at December 31,2023.

Subsequent Events

On March 5, 2024, the Company and ALOM entered into an amendment to the ALOM Agreement, pursuant to which ALOM agreed to waive the hourly account management charges and minimum monthly purchase requirements set forth in the ALOM Agreement for the period from January 2024 through June 2024, and the parties further agreed to extend the initial term of the agreement to December 31, 2024. The Company is currently evaluating alternative providers for the services provided by ALOM as an effort to continue to further reduce both direct and indirect costs associated with product manufacturing and distribution.
