Cash and Cash Equivalents

Basis of Presentation

The accompanying consolidated financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America (“GAAP”). Certain comparative amounts have been reclassified to conform to the current period presentation. Any reference in these notes to applicable guidance is meant to refer to the authoritative GAAP as found in the Accounting Standards Codification (“ASC”) or an Accounting Standards Update (“ASU”) issued by the Financial Accounting Standards Board (“FASB”).

Use of Estimates

The preparation of the consolidated financial statements in conformity with GAAP requires the Company’s management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the consolidated financial statements and the reported amount of expenses during the reporting period. Actual results could differ from those estimates. Management considers many factors in selecting appropriate financial accounting policies in developing the estimates and assumptions that are used in the preparation of the consolidated financial statements. Management must apply significant judgment in this process. Management’s estimation process often may yield a range of potentially reasonable estimates and management must select an amount that falls within that range of reasonable estimates. Estimates are used in the following areas, among others: accrued expenses and related research and development expenses.

Segments

Operating segments are defined as components of an enterprise for which separate and discrete information is available for evaluation by the chief operating decision-maker in deciding how to allocate resources and assess performance. The Company has one operating segment. The Company’s chief operating decision maker, its Chief Executive Officer, manages the Company’s operations on an aggregate basis for the purpose of allocating resources.

The Company considers highly-liquid investments purchased with an original maturity date of ninety days or less from the date of purchase to be cash equivalents. Cash and cash equivalents include cash held in banks and amounts held in money market funds. Cash equivalents are stated at cost, which approximates market value.

Marketable Securities

Investments in marketable debt securities are classified as available-for-sale. Marketable securities with maturities beyond one year may be classified as short-term based on their highly liquid nature and because such securities represent an investment of cash that is available for current operations.

Available-for-sale marketable securities are reported at fair value at each balance sheet date. Unrealized gains or losses are reported as a component of accumulated other comprehensive income (loss), a component of stockholders’ equity. Amortization and accretion of premiums and discounts are recorded in interest income. Realized gains and losses are included as a component of other income, net in the consolidated statements of operations.

The Company evaluates its marketable securities with unrealized losses for impairment. When assessing marketable securities for unrealized declines in value, the Company considers whether the decline in value is related to a credit loss or non-credit loss. For credit losses, the Company reduces the marketable security to fair value through an allowance for credit losses recorded to the balance sheet and corresponding charge to the statement of operations. The allowance for credit losses and corresponding impairment charge is adjusted each period for changes in fair value. For non-credit losses, the Company reduces the marketable security to fair value through a charge to the statement of comprehensive income (loss), reported as a component of accumulated other comprehensive income (loss) in stockholders’ equity. No credit losses were recorded during the periods presented.

Restricted Cash Equivalents

The Company had $2.4 million of restricted cash equivalents in the form of a letter of credit related to a lease at December 31, 2023 and 2022.

Comprehensive income (loss)

Comprehensive income (loss) includes net loss, as well as other changes in stockholders’ equity that result from transactions and economic events other than those with stockholders.

Concentrations of Credit Risk

Financial instruments that potentially expose the Company to concentrations of credit risk consist primarily of cash and cash equivalents, restricted cash equivalents and marketable securities. The Company maintains deposits in accredited financial institutions in excess of federally insured limits. The Company deposits its cash in financial institutions that it believes have high credit quality and has not experienced any losses on such accounts and does not believe it is exposed to any unusual credit risk beyond the normal credit risk associated with commercial banking relationships.

The Company’s marketable securities may consist of money market funds and marketable debt securities, including corporate bonds and U.S. Treasury securities. The Company’s investment policy limits instruments to investment grade securities with high credit quality issuers with the objective to preserve capital and to maintain liquidity until the funds can be used in business operations.

Fair Value Measurements

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. Financial assets and liabilities carried at fair value are to be classified and disclosed in one

of the following three levels of the fair value hierarchy, of which the first two are considered observable and the last is considered unobservable:

•

Level 1—Quoted prices in active markets for identical assets or liabilities.

•

Level 2—Observable inputs (other than Level 1 quoted prices), such as quoted prices in active markets for similar assets or liabilities, quoted prices in markets that are not active for identical or similar assets or liabilities, or other inputs that are observable or can be corroborated by observable market data.

•

Level 3—Unobservable inputs that are supported by little or no market activity that are significant to determining the fair value of the assets or liabilities, including pricing models, discounted cash flow methodologies and similar techniques.

To the extent that the valuation is based on models or inputs that are less observable or unobservable in the market, the determination of fair value requires more judgment. Accordingly, the degree of judgment exercised by the Company in determining fair value is greatest for instruments categorized in Level 3. A financial instrument’s level within the fair value hierarchy is based on the lowest level of any input that is significant to the fair value measurement.

Cloud Computing Arrangements

The Company capitalizes implementation costs for cloud computing arrangement service contracts. The Company’s cloud computing arrangements relate to its enterprise resource planning and manufacturing software. For such cloud computing service contracts, the Company capitalizes certain implementation costs as prepaid expenses in the consolidated balance sheets. The Company amortizes these capitalized cloud computing implementation costs into general and administrative expenses using the straight-line method over the fixed, non-cancellable term of the associated hosting arrangement, plus any reasonably certain renewal periods.

Property and Equipment, Net

Property and equipment, net is recorded at cost less accumulated depreciation. Depreciation expense is recorded using the straight-line method over the estimated useful life of the related asset, which are as follows:


	Estimated Useful Life
Computer equipment	3 years
Manufacturing equipment	5 years
Furniture and equipment	5 years
Laboratory equipment	5 years
Leasehold improvements	Shorter of remaining lease term or useful life

Purchased assets that are not yet in service are recorded to construction-in-process and no depreciation expense is recorded. Once they are placed in service, they are reclassified to the appropriate asset class. When assets are retired or otherwise disposed of, the assets and related accumulated depreciation are eliminated from the accounts and any resulting gain or loss is reflected in the Company’s consolidated statements of operation and comprehensive loss. Expenditures for maintenance and repairs are expensed as incurred.

Impairment of Long-Lived Assets

Long-lived assets consist of property and equipment. The Company continually evaluates whether events or circumstances have occurred that indicate that the estimated remaining useful life of its long-lived assets may warrant revision or that the carrying value of these assets may not be recoverable. If circumstances require that a long-lived asset or asset group be tested for impairment, the Company first compares the estimated undiscounted future cash flows expected to result from the use or disposition of that asset or asset group to its carrying amount. If the carrying amount of the long-lived asset or asset group is not recoverable on an undiscounted cash flow basis, an impairment loss would be recognized to the extent the carrying value exceeds its fair value. Fair value is determined through various valuation techniques including discounted cash flow models, quoted market prices and third-party independent appraisals, as considered necessary. No impairments occurred in the years ending December 31, 2023 and 2022.

Leases

At the inception of an arrangement, the Company determines whether the arrangement is or contains a lease. Leases with a term greater than one year are recognized on the consolidated balance sheet as a right-of-use (“ROU”) asset and current and non-current lease liabilities, as applicable. The Company has made an accounting policy election, known as the short-term lease recognition exemption, which allows the Company to not recognize ROU assets and lease liabilities that arise from short-term leases (12 months or less); The Company has applied this election to all classes of underlying assets. The Company typically only includes an initial lease term in its assessment of a lease arrangement. Options to renew or options to cancel a lease are not included in the Company’s assessment unless there is reasonable certainty that the Company will renew or will not cancel, respectively. The Company monitors its material leases on a quarterly basis.

Operating lease liabilities and their corresponding ROU assets are recorded based on the present value of future lease payments over the expected remaining lease term. Lease cost for operating leases is recognized on a straight-line basis over the lease term as an operating expense. Certain adjustments to the ROU asset may be required for items such as lease prepayments or incentives received. The interest rate implicit in lease contracts is typically not readily determinable. As a result, the Company utilizes its incremental borrowing rate, which reflects the fixed rate at which the Company could borrow on a collateralized basis the amount of the lease payments in the same currency, for a similar term, in a similar economic environment.

The Company has elected to account for the lease and non-lease components together for office, laboratory, and manufacturing real estate leases.

Research and Development

Research and development expenses include costs directly attributable to the conduct of the Company’s research and development programs.

Expenditures relating to research and development are expensed in the period incurred. Nonrefundable advance payments for goods and services that will be used in future research and development activities are expensed when the activity has been performed or when the goods have been received rather than when the payment is made. The cost of materials for a research and development activity that have an alternative future use is capitalized when the materials are acquired and recognized as expense as consumed. The costs of materials that were acquired for a particular research and development activity and have no alternative future use are expensed in the period acquired.

Costs incurred in obtaining licenses are recognized as research and development expense as incurred if the license has no alternative use.

Accrued Research and Development Expenses

The Company has entered into various research and development related contracts, including contracts with third-party contract research organizations and contract manufacturing organizations. These agreements are cancelable, and related payments are recognized as research and development expenses as incurred. The Company records accrued liabilities for estimated ongoing research costs. When evaluating the adequacy of the accrued liabilities, the Company analyzes the progress of the studies, including the phase or completion of events, invoices received and contracted costs. Significant judgments and estimates are made in determining the accrued balances at the end of any reporting period. Actual results could differ from the Company’s estimates. To date, the Company’s historical accrual estimates have not been materially different from the actual costs.

Stock-Based Compensation Expense

The Company accounts for stock-based compensation under the provisions of ASC 718-10, Compensation—Stock Compensation (“ASC 718-10”), which requires all share-based payments to employees, non-employees and directors, including grants of stock options and restricted stock, to be recognized in the consolidated statements of operations and comprehensive loss based on their fair values on the date of grant over the requisite service period, which is generally the vesting period of the respective award. Forfeitures are accounted for as they occur. Generally, the Company issues awards with only service-based vesting conditions and records the expense for these awards using the ratable method. The Company classifies stock-based compensation expense in the same manner in which the award recipient’s payroll or service provider’s costs are classified. Share-based payments that contain performance conditions are recognized when such conditions are probable of being achieved.

The fair value of each restricted common stock award and each restricted stock unit award is estimated on the date of grant based on the fair value of the Company’s common stock on that same date.

The fair value of each option grant is estimated on the date of grant using the Black-Scholes option pricing model which requires inputs based on certain subjective assumptions, including the following:

•

Fair Value of Common Stock— See the discussion below.

•

Expected Term—The expected term represents the period that the stock-based awards are expected to be outstanding. The Company uses the simplified method to determine the expected term, which is based on the average of the time-to-vesting and the contractual life of the options.

•

Expected Volatility—Because the Company does not have sufficient trading history for its common stock as of December 31, 2023, the expected volatility was estimated based on the average volatility for comparable publicly traded biotechnology companies over a period equal to the expected term of the stock option grants. The comparable companies were chosen based on the similar size, stage in life cycle or area of specialty. The Company will continue to apply this process until a sufficient amount of historical information regarding the volatility of its own stock price becomes available.

•

Risk-Free Interest Rate—The risk-free interest rate is based on the U.S. Treasury zero coupon issues in effect at the time of grant for periods corresponding with the expected term of the awards.

•

Dividend Yield—The Company has never paid dividends on its common stock and has no plans to pay dividends on its common stock. Therefore, the Company used an expected dividend yield of zero.

The Company began to use the closing common stock price as reported on the Nasdaq Global Select Market exchange as the fair value of common stock on the date of a grant subsequent to the Company's initial public offering of its common stock (“IPO”). Prior to the Company's IPO the estimated fair value of common stock was determined by the Company’s board of directors as of the date of each option grant, with input from management, considering third-party valuations of its common stock as well as the Company’s board of directors’ assessment of additional objective and subjective factors that it believed were relevant and which may have changed from the date of the most recent third-party valuation through the date of the grant. These objective and subjective factors include: (i) prices paid for the Company’s redeemable convertible preferred stock, and the rights, preferences, and privileges of the Company’s redeemable convertible preferred stock and common stock; (ii) the Company’s stage of development; (iii) the fact that the grants of stock-based awards related to illiquid securities in a private company; and (iv) the likelihood of achieving a liquidity event for the common stock underlying the stock-based awards, such as an initial public offering or sale of the Company, given prevailing market conditions. These third-party valuations were performed in accordance with the guidance outlined in the American Institute of Certified Public Accountants’ Accounting and Valuation Guide, Valuation of Privately Held Company Equity Securities Issued as Compensation. Each valuation methodology includes estimates and assumptions that require the Company’s judgment. The methodology utilized to estimate the fair value of the Company’s common stock was the option-pricing method (“OPM”) to back-solve the estimated value of the Company’s equity and corresponding value of the Company’s common stock.

Income Taxes

The Company accounts for income taxes using the asset and liability approach. Deferred tax assets and liabilities represent future tax consequences of temporary differences between the financial statement carrying amounts and the tax basis of assets and liabilities and for loss carryforwards using enacted tax rates expected to be in effect in the years in which the differences reverse. A valuation allowance is established to reduce deferred tax assets to the amounts expected to be realized. The Company also recognizes a tax benefit from uncertain tax positions only if it is “more likely than not” that the position is sustainable based on its technical merits. The Company accounts for interest or penalties related to uncertain tax positions as part of its provision for income taxes. To date, the Company has not incurred interest and penalties related to uncertain tax positions. Should such costs be incurred, they would be classified as a component of provision for income taxes.

Net Loss Per Share

Basic net loss per share is computed by dividing net loss by the weighted-average number of common shares outstanding during the reporting period, without consideration for potentially dilutive securities. Diluted net loss per share is computed by dividing net loss by the weighted-average number of common shares and potentially dilutive

securities outstanding during the periods. For purposes of the diluted net loss per share calculation, restricted stock, restricted stock units and stock options considered to be potentially dilutive securities were excluded from the calculation of diluted net loss per share because their effect would be anti-dilutive and therefore, basic and diluted net loss per share were the same for all reporting periods presented.

Recent Accounting Pronouncements and Recently Adopted Accounting Pronouncements

Recent Accounting Pronouncements

From time to time, new accounting pronouncements are issued and adopted by the Company as of the specified effective date. Unless otherwise discussed, the impact of recently issued standards that are not yet effective will not have a material impact on the Company’s consolidated financial statements upon adoption. Under the Jumpstart Our Business Startups Act of 2012, as amended (the “JOBS Act”), the Company meets the definition of an emerging growth company and has elected to take advantage of the extended transition period for complying with certain new or revised accounting standards pursuant to Section 107(b) of the JOBS Act.

Recently Issued Accounting Pronouncements Not Yet Adopted

In October 2023, the FASB issued ASU 2023-06 Disclosure Improvements: Codification Amendments in Response to the SEC’s Disclosure Update and Simplification Initiative (“ASU 2023-06”), which modifies certain disclosure and presentation requirements of a variety of Topics in the Codification and is intended to both clarify or improve such requirements and align the requirements with the SEC’s regulations. The effective date for each amendment is the effective date of the removal of the related disclosure from Regulation S-X or Regulation S-K, with early adoption prohibited. The Company will apply the provisions prospectively as such provisions become effective, and does not expect ASU 2023-06 to have a material impact on the consolidated financial statements.

In November 2023, the FASB issued ASU 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures (“ASU 2023-07”). ASU 2023-07 updates reportable segment disclosure requirements, primarily through enhanced disclosures about significant segment expenses and information used to assess segment performance. This update is effective beginning with the Company’s 2024 fiscal year annual reporting period, with early adoption permitted. The Company is currently evaluating the impact that the adoption of this standard will have on its consolidated financial statements and disclosures.

In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures (“ASU 2023-09”). ASU 2023-09 requires more detailed income tax disclosures, requiring entities to disclose disaggregated information about their effective tax rate reconciliation as well as expanded information on income taxes paid by jurisdiction. The disclosure requirements will be applied on a prospective basis, with the option to apply them retrospectively. This update is effective beginning with the Company’s 2025 fiscal year annual reporting period, with early adoption permitted. The Company is currently evaluating the impact that the adoption of this standard will have on its consolidated financial statements and disclosures.

2023 Inducement Plan

On August 25, 2023, the Company’s board of directors adopted the Company’s 2023 Inducement Plan (the “2023 Inducement Plan”) pursuant to which the Company reserved 3,500,000 shares of common stock for issuance under the 2023 Inducement Plan. The 2023 Inducement Plan provides for the grant of non-statutory stock options, restricted stock awards, restricted stock unit awards, stock appreciation rights, performance awards and other forms of stock-based compensation to eligible individuals. In accordance with Nasdaq Marketplace Rule 5635(c)(4), awards under the 2023 Inducement Plan may only be made to individuals not previously employees or directors of the Company (or following such individuals’ bona fide period of non-employment with the Company), as an

inducement material to the individuals’ entry into employment with the Company. Awards granted under the 2023 Inducement Plan must be approved by either a majority of the Company’s independent directors or the compensation committee of the Company’s board of directors. As of December 31, 2023, the Company had 3,263,436 shares of its common stock available for future issuance under the 2023 Inducement Plan.

Stock Incentive Plans

In December 2015, the Company’s board of directors adopted and approved the 2015 Stock Incentive Plan (as amended to date, the “2015 Plan”). The 2015 Plan provided for the granting of incentive stock options, non-statutory stock options, restricted stock awards and other stock-based awards to eligible employees, officers, directors, consultants and advisors as determined by the Company’s board of directors.

In February 2021, the Company’s board of directors adopted and stockholders approved the 2021 Equity Incentive Plan (the “2021 Plan”). The 2021 Plan became effective on February 5, 2021, following which no further grants were or will be made under the 2015 Plan. The 2021 Plan provides for the grant of stock options, non-statutory stock options, restricted stock awards, restricted stock unit awards, stock appreciation rights, performance stock awards and other forms of stock compensation to our employees, consultants and directors.

The number of shares of our common stock reserved for issuance under our 2021 Plan will automatically increase on January 1 of each year through January 1, 2031, by 4.0% of the total number of shares of common stock outstanding on December 31 of the preceding calendar year. Any grants that expire or are canceled, terminated, forfeited, fail to vest, or are withheld to satisfy a tax withholding obligation are allowed to be reissued under 2021 Plan. As of December 31, 2023, the Company had 1,270,867 shares of its common stock available for future issuance under the 2021 Plan.

Stock Options

The Company’s stock options generally vest over 48 months with 25% vesting after one year followed by ratable monthly vesting over three years and have a contractual term of 10 years. The weighted-average assumptions used principally in determining the fair value of options granted were as follows:


	Year Ended December 31,
	2023			2022
Fair value of common stock	$	4.94		$	4.78
Expected term (in years)		6.0			5.9
Expected volatility		81.7	%		78.8	%
Risk-free interest rate		3.8	%		2.5	%
Dividend yield		—			—

The following table summarizes the Company’s stock option activity for the year ended December 31, 2023:


	Shares			Weighted- Average Exercise Price		Weighted- Average Remaining Contractual Term (in years)		Aggregate Intrinsic Value (in thousands)
Outstanding at December 31, 2022		6,471,524		$	6.69		8.28	$	14,949
Granted		2,347,469			4.94
Vested and exercised		(94,028	)		1.85
Forfeited		(358,336	)		7.41
Expired		(76,552	)		12.09
Outstanding at December 31, 2023		8,290,077		$	6.17		7.71	$	999
Exercisable at December 31, 2023		4,539,019		$	6.19		7.02	$	880

The aggregate intrinsic value of options is calculated as the difference between the exercise price of the stock options and the fair value of the Company’s common stock for those stock options that had exercise prices lower than the fair value of the common stock as of the respective date.

The weighted-average grant-date fair value of stock options granted during the years ended December 31, 2023 and 2022 was $3.56 and $7.10 per share, respectively. As of December 31, 2023, total unrecognized

compensation expense related to stock options was $14.0 million which is expected to be recognized over a weighted-average period of 2.3 years. The intrinsic value of stock options exercised was $0.1 million for the year ended December 31, 2023.

As of December 31, 2023 and 2022, options for 10,299 and 83,459 shares with weighted average exercise prices of $4.90 and $2.23 were exercised and unvested, respectively. The underlying proceeds from the unvested exercises of less than $0.1 million and $0.2 million is recorded in other current liabilities as of December 31, 2023 and 2022, on the consolidated balance sheet.

Restricted Stock Units

As of December 31, 2023, there were 1,113,381 restricted stock units outstanding under the 2021 Plan and the 2023 Inducement Plan. The following table summarizes the Company's unvested restricted stock unit activity for the year ended December 31, 2023:


	Shares			Weighted-Average Grant Date Fair Value
Unvested at December 31, 2022		1,430,200		$	5.49
Granted		801,611			4.88
Vested		(1,019,846	)		5.59
Forfeited		(98,584	)		5.71
Unvested at December 31, 2023		1,113,381		$	4.94

As of December 31, 2023, total unrecognized compensation expense related to the unvested restricted stock units was $4.6 million, which is expected to be recognized over a weighted average period of 2.2 years.

2021 Employee Stock Purchase Plan

In February 2021, the Company’s board of directors adopted and stockholders approved the 2021 Employee Stock Purchase Plan (the “ESPP”). The ESPP became effective on February 5, 2021. The number of shares of common stock reserved for issuance under the ESPP will automatically increase on January 1 of each year through January 1, 2031, by the lesser of (i) 1% of the total number of shares of our common stock outstanding on December 31 of the preceding calendar year, and (ii) 1,800,000 shares. If purchase rights granted under the ESPP terminate without having been exercised, the shares of common stock not purchased under such purchase rights will again become available for issuance under the ESPP. As of December 31, 2023, the Company had 1,289,604 shares of its common stock available for future issuance under the ESPP.

The ESPP permits eligible employees to purchase common stock through accumulated payroll deductions at a purchase price equal to 85% of the lesser of the market value of the common stock at the beginning of the 6-month offering period or on the purchase date. During the years ended December 31, 2023 and 2022, the Company issued 82,703 and 34,242 shares with a weighted average purchase price of $2.73 and $3.41 during the year ended December 31, 2023, which resulted in an immaterial amount of compensation expense.

The Company has weighed the positive and negative evidence to assess the recoverability of its deferred tax assets. Realization of future tax benefits is dependent on many factors, including the Company’s ability to generate taxable income. After this assessment, the Company determined it was more likely than not that the Company will not realize the benefit of its deferred tax assets. As a result, the Company has provided a full valuation allowance against its net deferred tax assets. The valuation allowance for deferred tax assets as of December 31, 2023 and 2022 was $104.4 million and $68.3 million, respectively. For the years ended December 31, 2023 and 2022, the Company recorded an increase in the valuation allowance of $36.1 million and $28.9 million, respectively, primarily related to net operating losses incurred by the Company.

As of December 31, 2023, the Company had gross U.S. federal net operating loss carryforwards of $190.2 million including $188.3 million that had an indefinite carryforward period and $1.9 million that were subject to expiration at various dates through 2037. As of December 31, 2023, the Company had state net operating loss carryforwards of $180.8 million which will expire at various dates through 2043. As of December 31, 2023, the Company had U.S. federal research and development tax credit carryforwards of $12.2 million which will expire at various dates through 2042 and state research and credit carryforwards of $6.1 million which will expire at various

dates through 2038. The net operating loss and tax credit carryforwards are subject to review and possible adjustment by the Internal Revenue Service and state tax authorities.

Net operating loss and tax credit carryforwards may become subject to an annual limitation in the event of certain cumulative changes in the ownership interest of significant shareholders over a three-year period in excess of 50%, as defined under Sections 382 and 383 of the Code, respectively, as well as similar state provisions. This could limit the amount of tax attributes that can be utilized annually to offset future taxable income or tax liabilities. The amount of the annual limitation is determined based on the value of the Company immediately prior to the ownership change. Subsequent ownership changes may further affect the limitation in future years. The Company has not determined whether an ownership change has occurred and as such, the Company’s net operating losses may be limited. Any limitation may result in expiration of a portion of the net operating loss carryforwards or research development credit carryforwards before utilization.

The Company has not, as yet, conducted a study of research and development credit carryforwards. Such a study, once undertaken by the Company, may result in an adjustment to the research and development credit carryforwards. However, a full valuation allowance has been provided against the Company’s research and development credits and, if any adjustment is required, such adjustment would be offset by an adjustment to the valuation allowance. Thus, there would be no impact to the balance sheet or statement of operations if any adjustment is required.

As of December 31, 2023 and 2022, the Company did not have any unrecognized tax benefits. Any future interest and penalties related to income tax matters would be recognized in the provision for income tax. As of December 31, 2023 and 2022, the Company did not have a balance of accrued interest and penalties related to uncertain tax positions.

The Company files income tax returns in the United States and various states. As of December 31, 2023, there were no income tax examinations in progress.

The tax years 2020 through present remain open to examination by major taxing jurisdictions to which the Company is subject, which are primarily in the United States. In addition, tax years prior to 2019 resulted in losses and the Company also generated research and development tax credits during those years. Since carryforward attributes generated in these years may be utilized in future years, years prior to 2019 may still be adjusted upon examination by the Internal Revenue Service or state tax authorities if they have or will be used in a future period.

The entire disclosure for income taxes. Disclosures may include net deferred tax liability or asset recognized in an enterprise's statement of financial position, net change during the year in the total valuation allowance, approximate tax effect of each type of temporary difference and carryforward that gives rise to a significant portion of deferred tax liabilities and deferred tax assets, utilization of a tax carryback, and tax uncertainties information.
