ARS Pharmaceuticals, Inc.

1. Nature of Business

Description of Business

ARS Pharmaceuticals, Inc. (“ARS”, “ARS Pharma” or the “Company”) is a biopharmaceutical company focused on the commercialization and development ofneffy (currently identified in the EU by the trade name EURneffy) for the needle-free intranasal delivery of epinephrine for the emergency treatment of Type I allergic reactions, including anaphylaxis. neffy is the first and only FDA and European Commission-approved needle-free epinephrine product, and the first new delivery method for epinephrine in more than 35 years.

The Company incorporated in Delaware in January 2016 and is located in San Diego, California. The Company has a wholly owned subsidiary, ARS Pharmaceuticals Operations, Inc., incorporated in Delaware in August 2015, through which it conducts substantially all its operations. ARS Pharmaceuticals Operations, Inc. has a wholly owned subsidiary in Ireland, ARS Pharmaceuticals IRL, Limited, to facilitate the filing of regulatory approval forneffyin European countries.

Liquidity and Capital Resources

The accompanying financial statements have been prepared assuming that the Company will continue as a going concern. The Company has incurred net operating losses in most years since its inception and had an accumulated deficit of$157.2 million as of March 31, 2025. The Company had cash, cash equivalents, and short-term investments of$275.7 million as of March 31, 2025 and has not generated positive cash flows from operations in most years. To date, the Company has funded its operations primarily with proceeds from the merger with Silverback in November 2022 (the “Merger”), private placement of convertible preferred stock, issuance of common stock, licensing, supply and distribution agreements, bank debt, and limited net product sales. The Company’s currently available cash, cash equivalents, and short-term investments as of March 31, 2025 are sufficient to meet its anticipated cash requirements for at least the 12 months following the date these financial statements are issued.

From August 5, 2015 (inception) through March 31, 2025, the Company has devoted substantially all of its efforts to developing intellectual property, conducting product development and clinical trials, organizing and staffing the Company, business planning, raising capital, building infrastructure, pre-commercial and commercial activities, and providing general and administrative support for these operations. The Company has a limited operating history, and the sales and income potential of the Company’s business and market are unproven. Management expects operating expenses to increase for the foreseeable future, and there can be no assurance that the Company will achieve profitability in the future, or if achieved, that it will be sustained on a continuing basis.

2. Summary of Significant Accounting Policies

Basis of Presentation and Principles of Consolidation

The financial statements have been prepared in conformity with U.S. generally accepted accounting principles (“U.S. GAAP”). Any reference in these notes to applicable guidance is meant to refer to the authoritative U.S. GAAP as found in the Accounting Standards Codification (“ASC”), and Accounting Standards Update (“ASU”), of the Financial Accounting Standards Board (“FASB”). The Company’s financial statements are presented on a condensed consolidated basis, which include the accounts of ARS Pharmaceuticals, Inc., ARS Pharmaceuticals Operations, Inc. and ARS Pharmaceuticals IRL, Limited. All intercompany accounts and transactions have been eliminated in consolidation. The Company’s functional and reporting currency is the U.S. dollar. Assets and liabilities that are not denominated in the functional currency are remeasured into U.S. dollars at foreign currency exchange rates in effect at the balance sheet date except for nonmonetary assets, which are remeasured at historical foreign currency exchange rates in effect at the date of transaction. Net realized and unrealized gains and losses from foreign currency transactions and remeasurement are reported in other income in the condensed consolidated statements of operations and comprehensive loss. All adjustments considered necessary for a fair presentation have been included.

Unaudited Interim Condensed Consolidated Financial Statements

The accompanying condensed consolidated balance sheet as of March 31, 2025, the condensed consolidated statements of operations and comprehensive loss for the three months ended March 31, 2025 and 2024, the condensed consolidated statements of stockholders’ equity for the three months ended March 31, 2025 and 2024, and the condensed consolidated statements of cash flows for the three months ended March 31, 2025 and 2024, are unaudited. The balance sheet as of December 31, 2024 was derived from the audited financial statements as of and for the year ended December 31, 2024. The unaudited interim condensed consolidated financial statements have been prepared on a basis consistent with the audited annual financial statements as of and for the year ended December 31, 2024, and, in the opinion of management, reflect all adjustments, consisting solely of normal recurring adjustments, necessary for the fair presentation of the Company’s financial position as of March 31, 2025, the condensed consolidated results of its operations for the three months ended March 31, 2025 and 2024, and its cash flows for the three months ended March 31, 2025 and 2024. The financial data and other information disclosed in these notes related to the three months ended March 31, 2025 and 2024 are also unaudited. The condensed consolidated results of operations for the three months ended March 31, 2025 are not necessarily indicative of the results to be expected for the full year ending December 31, 2025 or any other period.

Use of Estimates

The preparation of the Company’s condensed consolidated financial statements requires it to make estimates and assumptions that impact the reported amounts of assets, liabilities, revenues and expenses and the disclosure of contingent assets and liabilities in the Company’s condensed consolidated financial statements and accompanying notes. The most significant estimates in the Company’s condensed consolidated financial statements are revenue recognized under collaboration agreements, accruals for variable components of product revenue, accruals for research and development expenses, valuation of equity awards, and measurement of the financing liability. These estimates and assumptions are based on current facts, historical experience and various other factors believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities and the recording of revenue and expenses that are not readily apparent from other sources. Actual results may differ materially and adversely from these estimates. To the extent there are material differences between the estimates and actual results, the Company’s future results of operations will be affected.

Cash and Cash Equivalents

Cash and cash equivalents include cash readily available in checking, money market mutual funds, and short-term investments with remaining maturities when purchased of 90 days or less. The Company considers all highly liquid investments with remaining maturities when purchased of 90 days or less to be cash equivalents.

Accounts Receivable and Allowance for Credit Losses

Accounts receivable includes trade accounts receivable from product sales to customers and reimbursable costs to partners under the Company’s collaboration agreements. Trade accounts receivable are recorded at wholesale acquisition cost (“WAC”), less purchase price discounts, prompt pay discounts, chargebacks, and an allowance for credit losses, if any. The allowance for credit losses is the Company’s estimate of losses over the life of the receivables. The Company determines the allowance for credit losses for accounts receivable based on each customer’s or partner’s accounts receivable balance and age, their financial condition, and the general economic environment. The Company must also use professional judgment for its allowance for credit losses on trade accounts receivable asneffywas commercially launched in September 2024 and historical data is limited. The Company is currently operating under the Title Agreement (as defined in Note 3 – Revenue) with its Title Agent (as defined in Note 3 – Revenue) and the Title Agent retains all credit and collection risk on product sales to the Company’s wholesale distributors and pharmacy customers.

When the collectability of an invoice is no longer probable, the Company will create a reserve for that specific receivable. If a receivable is determined to be uncollectible, it is charged against the general credit loss reserve or the reserve for the specific receivable, if one exists. No allowance for credit losses was deemed necessary at March 31, 2025 or December 31, 2024.

Investments

The Company invests excess cash in investment grade fixed income securities. These investments are included in short-term investments on the condensed consolidated balance sheets, classified as available-for-sale, and reported at fair value with unrealized gains and losses included in accumulated other comprehensive gain, net. Realized gains and losses on the sale of securities are recognized in net loss.

Fair Value of Financial Instruments

Cash, cash equivalents, and short-term investments are carried at fair value. The carrying amounts of all accounts receivable, prepaid expenses and other current assets, accounts payable, accrued liabilities, and contract liability are considered to be representative of their respective fair values because of the short-term nature of those instruments.

Concentrations of Credit Risk

Financial instruments that potentially subject the Company to significant concentrations of credit risk consist primarily of cash, cash equivalents, and short-term investments. The Company maintains deposits in federally insured financial institutions in excess of federally insured limits and limits its exposure to cash risk by placing its cash with high credit quality financial institutions.

The Company reviews its financial instruments portfolio on a quarterly basis to determine if any unrealized losses have resulted from a credit loss or other factors. As part of the review, management considers factors such as historical experience, market data, issuer-specific factors, and current economic conditions. This review is subjective, as it requires management to evaluate whether an event or change in circumstances has occurred in that period that may be related to credit issues.

The Company is also subject to credit risk related to its trade accounts receivable from product sales. neffy is distributed primarily through wholesale distributors and pharmacies. These entities are not obligated to purchase any set number of units and they distribute neffyon demand as orders are received. The Company extends credit to its customers in the normal course of business after evaluating their overall financial condition. As stated above, the Company is currently operating under the Title Agreement with its Title Agent (as defined in Note 3 – Revenue) and the Title Agent retains all credit and collection risk on sales to the Company’s wholesale distributors and pharmacy customers. The Company’s Title Agent accounts for 90% and 93% of its trade accounts receivable balance as of March 31, 2025 and December 31, 2024, respectively. For the three months ended March 31, 2025, the Company’s five largest customers combined accounted for 90% of its gross product sales. Historically, the Company has not experienced any credit losses from product sales. For thethree months ended March 31, 2025, one customer accounted for 100% of revenue under collaboration agreements.

Inventories

Inventories consist of finished goods held for sale and distribution, raw materials and work in process, and include labor and overhead. Inventories are stated at the lower of cost or net realizable value, and are determined on a first-in, first-out basis. Net realizable value is the estimated selling price in the ordinary course of business, less reasonably predictable costs of completion, disposal, and transportation. The Company periodically reviews its inventory to identify obsolete, slow-moving, or otherwise unsalable inventories, and establishes allowances for situations in which the cost of the inventory is not expected to be recovered. Such impairment charges, if any, are recorded in cost of goods sold, on the condensed consolidated statements of operations.

The Company capitalizes inventory costs after regulatory approval, when future commercialization is considered probable, and a future economic benefit is expected to be realized. Prior to regulatory approval, the Company records inventory costs as research and development expenses. As such, when regulatory approval is received, this may result in zero-cost inventory which does not have a carrying value. This inventory is available to the Company to utilize for commercial operations as well as ongoing research and development activities.

Property and Equipment

Property and equipment are stated at cost less accumulated depreciation. Depreciation is calculated using the straight-line method over the estimated useful lives of the assets, generally five years. Repair and maintenance costs are charged to expense as incurred.

Impairment of Long-Lived Assets

Long-lived assets consist primarily of property and equipment and intangible assets. The Company reviews its long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying value of an asset may not be recoverable. Recoverability is measured by comparison of the carrying amount to the future undiscounted net cash flows which the asset or asset group are expected to generate, including its eventual residual value. If such assets are considered to be impaired, the impairment to be recognized is measured as the amount by which the carrying amount of the assets exceeds its fair value. The Company has not recognized any impairment losses from inception through March 31, 2025.

Leases

The Company determines the initial classification and measurement of its right-of-use (“ROU”) asset and lease liabilities at the lease commencement date and thereafter, if modified. The Company recognizes a ROU asset for its operating leases with lease terms greater than 12 months. The lease term includes any renewal options and termination options that the Company is reasonably assured to exercise. The lease liability is calculated by using the present value of all lease payments, with the present value determined by using the incremental borrowing rate for operating leases determined by using the incremental borrowing rate of interest that the Company would pay to borrow on a collateralized basis an amount equal to the lease payments in a similar economic environment as well as a review of peer companies. Variable charges for common area maintenance and other variable costs are recognized as expense as incurred. Rent 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 research and development and general and administrative expenses in the condensed consolidated statements of operations and comprehensive loss.

Intangible Assets

Intangible assets are measured at fair value as of the acquisition date or, in the case of commercial milestone payments, the date they become due. The evaluation of intangible assets includes assessing the amortization period for which the asset is expected to contribute to the future cash flows of the Company. Intangible assets with finite useful lives are amortized over their estimated useful lives, primarily on a straight-line basis when the Company is unable to reliably estimate the pattern of cash flow.

Revenue Recognition

The Company’s revenues consist of product sales ofneffyand revenue derived from its collaboration and out-licensing agreements. See Note 3 – Revenue for more detail on product revenue, and Note 8 – Collaboration and Out-Licensing for more detail on revenue from collaboration agreements, out-licensing agreements, and supply agreements.

The Company recognizes revenue in accordance with ASC Topic 606, Revenue from Contracts with Customers (“ASC 606”). The provisions of ASC 606 require the following steps to determine revenue recognition: (i) identification of the promised goods or services in the contract; (ii) determination of whether the promised goods or services are performance obligations including whether they are distinct in the context of the contract; (iii) measurement of the transaction price, including the constraint on variable consideration; (iv) allocation of the transaction price to the performance obligations based on estimated selling prices; and (v) recognition of revenue when (or as) the Company satisfies each performance obligation. At contract inception, the Company assesses the goods or services promised within each contract, determines whether each promised good or service is distinct and identifies those that are performance obligations. The Company 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.

Cost of Goods Sold

Cost of goods sold primarily consists of direct and indirect costs related to the manufacture ofneffyfor commercial sale, including salaries and related expenses for personnel, stock-based compensation, third-party manufacturing costs, raw material and component costs, packaging services, freight, storage costs, distribution fees, amortization of capitalized in-licensed costs, supply agreement fees, and royalties on product sales. Prior to the FDA approval ofneffyin August 2024, costs incurred for the manufacture ofneffy were recorded as research and development expenses, which resulted in zero-cost inventory. As a result, the cost of goods sold related toneffy will initially reflect a lower average per unit cost of materials, as previously expensed zero-cost inventory is utilized for commercial production and sold to customers.

Research and Development Costs

Research and development costs are expensed in the period incurred. Research and development costs primarily consist of salaries and related expenses for personnel, stock-based compensation expense, external research and development costs incurred under agreements with contract research organizations, investigative sites and consultants to conduct clinical studies, costs related to compliance with regulatory requirements, costs related to manufacturing the Company’s product candidates (including neffy prior to FDA approval in August 2024) for clinical trials, and other allocated expenses.

Payments for research and development activities are based on the terms of the individual agreements, which may differ from the pattern of costs incurred, and payments made in advance of performance are reflected in the accompanying condensed consolidated balance sheets as prepaid expenses. The Company records accruals for estimated costs incurred for ongoing research and development activities. When evaluating the adequacy of the accrued liabilities, the Company analyzes progress of the services, including the phase or completion of events, invoices received and contracted costs. The Company uses judgments and estimates to determine the prepaid or accrued balances at the end of any reporting period. Actual results could differ from the Company’s estimates.

Selling, General and Administrative Costs

Selling, general and administrative costs are expensed in the period incurred. Selling, general and administrative costs primarily consist of marketing-related expenses, salaries and related expenses for personnel, including meals and travel-related expenses incurred by the sales team, stock-based compensation, legal fees incurred relating to corporate and patent matters, professional fees incurred for accounting, auditing, tax, and other consulting services, and insurance costs.

Advertising

Costs for producing advertising are expensed when incurred. Costs for communicating advertising, such as search engine marketing, banner advertisements, social media advertisements, and print advertisements, are recorded as prepaid expenses and then expensed when the advertisement occurs. For the three months ended March 31, 2025, advertising costs were$11.0 million. No advertising costs were incurred for thethree months ended March 31, 2024.

Patent Costs

Costs related to filing and pursuing patent applications are recorded as general and administrative expenses in the statements of operations and expensed as incurred since recoverability of such expenditures is uncertain.

License Fees

Costs incurred to acquire technology licenses and milestone payments made on existing agreements are expensed or capitalized based upon the asset achieving technological feasibility in accordance with management’s assessment regarding the ultimate recoverability of the amounts paid and the potential for alternative future use.

Stock-Based Compensation

Stock-based compensation expense represents the cost of the grant date fair value of stock option grants recognized over the requisite service period of the awards (usually the vesting period) on a straight-line basis. The Company recognizes expense for awards subject to performance-based milestones over the remaining service period when management determines that achievement of the milestone is probable. Management evaluates when the achievement of a performance-based milestone is probable based on the expected satisfaction of the performance conditions at each reporting date. The Company estimates the fair value of stock option grants using the Black-Scholes option pricing model and recognizes forfeitures as they occur. In the event that stock-based awards are granted in contemplation of or shortly before a planned release of material non-public information, and such information is expected to result in a material increase in the share price of the Company’s common stock, the Company may consider whether an adjustment to the observable market price is required when estimating the grant date fair value.

Comprehensive Loss

Comprehensive loss is defined as the change in equity during a period from transactions and other events and circumstances from non-owner sources. The Company’s comprehensive loss typically consists of the change in unrealized gains and losses on available-for-sale securities.

Segment Reporting

Operating segments are components of an enterprise about which separate discrete financial information is available for evaluation by the chief operating decision-maker for purposes of making decisions regarding resource allocation and assessing performance. The Company views its operations and manages its business asone operating segment.

Net Loss Per Share

Basic net loss per share attributable to common stockholders is calculated by dividing the net loss attributable to common stockholders by the weighted-average number of shares of common stock outstanding for the period, without consideration of potentially dilutive securities. Diluted net loss per share attributable to common stockholders is the same as basic net loss per share attributable to common stockholders since the effect of potentially dilutive securities is anti-dilutive given the net loss of the Company. For purposes of this calculation, stock options, warrants, and unvested restricted stock units, are considered to be common stock equivalents but are not included in the calculations of diluted net loss per share for the periods presented as their effect would be antidilutive.

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

Recently Adopted Accounting Pronouncements

In November 2023, the FASB issued ASU No. 2023-07, Segment Reporting (Topic 280)–Improvements to Reportable Segment Disclosures(“ASU 2023-07”), which requires issuers to make additional disclosures with respect to segment expenses, including required disclosure on an annual and interim basis for significant segment expenses and other segment items. ASU 2023-07 also permits the disclosure of more than one measure of a segment’s profit or loss. ASU 2023-07 was effective for the Company on January 1, 2024 for annual periods and on January 1, 2025 for interim periods. The adoption of ASU 2023-07 resulted in enhanced disclosures as included in Note 15 – Segment Information and did not impact the Company’s condensed consolidated financial statements.

Recently Issued Accounting Pronouncements — Not Yet Adopted

From time to time, new accounting pronouncements are issued by the FASB or other standards setting bodies that are adopted as of the specified effective date. The Company believes the impact of recently issued standards, other than those noted below, and any issued but not yet effective standards will not have a material impact on our financial statements upon adoption.

In December 2023, the FASB issued ASU No. 2023-09, Income Taxes (Topic 740)–Improvements to Income Tax Disclosures(“ASU 2023-09”). The new standard requires a company to expand its existing income tax disclosures, specifically related to the rate reconciliation and income taxes paid. The amendments in this update are effective for annual periods beginning after December 15, 2024, with early adoption permitted. The Company does not expect to early adopt the new standard. The new standard is expected to be applied prospectively, but retrospective application is permitted. The Company is currently evaluating the impact of ASU 2023-09 on the financial statements and related disclosures.

In November 2024, the FASB issued ASU No. 2024-03, Income Statement–Reporting Comprehensive Income–Expense Disaggregation Disclosures (Subtopic 220-40) (“ASU 2024-03”). The amendments in this update require disclosure, in the notes to the financial statements, of specific expense categories present within expense captions presented on the face of the income statement within continuing operations of public business entities. The amendments in this update are effective for annual periods beginning after December 15, 2026 and interim periods beginning after December 15, 2027. Early adoption is permitted. The amendments should be applied either prospectively to financial statements issued for reporting periods after the effective date of this ASU or retrospectively to any and all prior periods presented in the financial statements. The impact of adoption of this ASU on the Company’s disclosures is currently being evaluated.

3. Revenue

The Company’s revenues consist primarily of product sales ofneffy, revenue derived from its collaboration and out-licensing agreements, and revenue from its supply agreements. See Note 8 – Collaboration and Out-Licensing for further discussion related to revenue from collaboration, out-licensing, and supply agreements.

Product Revenue

neffywas approved by the FDA in August 2024, and the Company began generating product revenue from sales ofneffyin September 2024. The Company uses a third-party logistics provider (“3PL Agent”) to fulfill orders ofneffyto the Company’s customers. The 3PL Agent provides services to the Company that include warehousing, distribution, order and accounts receivable management, and data management.

The Company entered into a title model agreement (“Title Agreement”) with an affiliate of the 3PL Agent (the “Title Agent”) so that the Title Agent may purchase and take title toneffyand then sell it to the Company’s wholesale distributors and pharmacy customers that have contracted to make a purchase. Under the Title Agreement, the economic substance of the transaction is such that the Company does not recognize revenue until neffyis sold and title has transferred from the Title Agent to a wholesale distributor or pharmacy.

The Company also entered into sales agreements with pharmacies that are not subject to the Title Agreement. Under these agreements, the pharmacy holds neffy under consignment. Under the consignment model, the Company recognizes revenue when neffy is sold to a patient, at which point title transfers from the Company directly to the patient.

Product revenue is recorded with each sale at the transaction price, net of reserves for variable components, including but not limited to distribution service fees, prompt pay discounts, product returns, chargebacks, rebates, and co-payment assistance, which are collectively referred to as “Gross-to-Net Adjustments.” Estimates for Gross-to-Net Adjustments are reassessed each reporting period, and adjustments are recorded on a cumulative catch-up basis, which would affect product revenue and net loss in the period of adjustment. Trade accounts receivable due to the Company from contracts with its customers are stated in the condensed consolidated balance sheet, net of various allowances as described in the Accounts Receivable and Allowance for Credit Losses policy in Note 2 – Summary of Significant Accounting Policies.

The Company utilizes the expected value method when estimating the amount of variable consideration to include in the transaction price with respect to each of the foregoing variable components. Variable consideration is included in the transaction price only to the extent it is probable that a significant revenue reversal will not occur when the uncertainty associated with the variable consideration is resolved.

In accordance with ASC 606, the Company must make significant judgments to determine the estimate for certain Gross-to-Net Adjustments. The specific considerations that the Company uses in estimating the amounts related to Gross-to-Net Adjustments are as follows:

Distribution Service Fees. The Company pays distribution service fees to its wholesale distributors. These fees are a contractually fixed percentage of WAC and are calculated at the time of sale based on the purchased amount. These fees are recorded as other current liabilities on the condensed consolidated balance sheets.

Commercial Pharmacy Discounts. The Company provides discounts to its pharmacy customers. These discounts are a contractually fixed percentage of WAC and are a direct reduction from the WAC price they are charged. They are calculated at the time of sale based on the purchased amount. These discounts are recorded as contra trade accounts receivable on the condensed consolidated balance sheets.

Prompt Pay Discounts. The Company incentivizes on time invoice payments through prompt pay discounts. Prompt pay discounts are typically taken by customers, so an estimate of the discount is recorded at the time of sale based on the purchased amount. Prompt pay discount estimates are recorded as contra trade accounts receivable on the condensed consolidated balance sheets.

Chargebacks. Certain government entities and covered entities (e.g. Veterans Administration, 340B covered entities) can purchase the product at a price discounted below WAC. The difference between the government or covered entity purchase price and WAC will be charged back to the Company. The Company estimates the amount of chargebacks based on the expected number of claims and the related cost that is associated with the revenue being recognized for product that remains in the distribution channel at the end of each reporting period. Estimated chargebacks are recorded as contra trade accounts receivable on the condensed consolidated balance sheets.

Rebates. The Company provides commercial rebates to pharmacy benefit managers and managed care organizations and is subject to mandatory discount obligations under the Medicare, Medicaid, and Tricare programs. The rebate amounts for these programs are determined by contractual arrangements or statutory requirements. Rebates are owed after the product has been dispensed to a patient and the Company has been invoiced. The Company estimates the amount in rebates based on the expected number of claims and the related cost that is associated with the revenue being recognized for product that remains in the distribution channel at the end of each reporting period. Rebate estimates are recorded as other current liabilities on the condensed consolidated balance sheets.

Co-payment Program. The Company offers co-payment assistance programs to commercially insured patients whose insurance requires a co-payment to be made when filling their prescription. The Company estimates the amount of co-payment assistance based on the expected volume and the average buy down rate associated with the revenue being recognized for product that remains in the distribution channel at the end of each reporting period. Co-payment programs estimates are recorded as other current liabilities on the condensed consolidated balance sheets.

Product Returns. Customers have the right to return damaged product, product that is within six months or less of the labeled expiration date, or product that is past the expiration date by no more than twelve months. neffywas commercially launched in September 2024 and due to the lack of historical sales and returns data, the Company used professional judgment and industry data to estimate returns. As time passes and historical data becomes available, the Company will use historical sales and returns data to estimate future product returns. A reserve for potential product returns is recorded as other current liabilities on the condensed consolidated balance sheets.

4. Inventories

The Company began to capitalize the inventory costs associated with neffy upon FDA approval in August 2024 when future commercialization was considered probable, and it was determined that the inventory had a probable future economic benefit. These inventory costs consist primarily of purchased materials, third-party manufacturing costs, and packaging and serialization services. Noncurrent inventory consists of inventory anticipated to remain on hand for more than one year from the balance sheet date.

Capitalized inventories consisted of the following (in thousands):

Prior to FDA approval in August 2024, costs incurred for the manufacturing ofneffy were recorded as research and development expenses, which upon approval resulted in zero-cost inventory. The Company held$10.9 million and$11.7 million in zero-cost inventory as of March 31, 2025 and December 31, 2024, respectively, none of which was determined to be obsolete as of each period end. The Company expects to fully utilize its zero-cost inventory in future periods.

5. Fair Value Measurements

The Company categorizes its assets and liabilities measured at fair value in accordance with the authoritative accounting guidance that establishes a consistent framework for measuring fair value and expands disclosures for each major asset and liability category measured at fair value on either a recurring or nonrecurring basis. Fair value is defined as the exit price, representing the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. As such, fair value is a market-based measurement that should be determined based on assumptions that market participants would use in pricing an asset or liability. As a basis for considering such assumptions, the guidance establishes a three-tier fair value hierarchy, which prioritizes the inputs used in measuring fair value as follows:

The following table identifies the Company’s assets that were measured at fair value on a recurring basis (in thousands):

There wereno transfers between the Level 1 and Level 2 categories or into or out of the Level 3 category during the periods presented. During thethree months ended March 31, 2025, the Company purchased$34.3 million in short-term investments and there were$63.5 million in maturities of short-term investments. During the three months ended March 31, 2024, the Company purchased$63.4 million in short-term investments and there were$55.0 million in maturities of short-term investments.

The Company’s short-term investments portfolio contains investments in U.S. Treasury securities that have an effective maturity date that is less than one year from the respective balance sheet date. The Company's money market mutual fund holdings are highly liquid and invest primarily in cash and U.S. Treasury securities.

There was a$0.1 million net unrealized gain on available-for-sale securities for the three months ended March 31, 2025, and a$0.2 million unrealized loss on available-for-sale securities for the three months ended March 31, 2024. Management determined that the gross unrealized losses on the Company’s available-for-sale securities as of March 31, 2025 were primarily attributable to current economic and market conditions and not credit risk. As of March 31, 2025 and December 31, 2024, no allowance for credit losses was recorded. It is neither management’s intention to sell nor is it more likely than not that the Company will be required to sell any investments prior to recovery of its amortized cost basis, which is expected to be at maturity.

Accrued interest on the Company's available-for-sale securities was$1.0 million as of March 31, 2025 and is included in prepaid expenses and other current assets in the accompanying condensed consolidated balance sheet.

As of March 31, 2025 and December 31, 2024, the Company didnot have any liabilities that were measured at fair value on a recurring basis.

6. Balance Sheet Details

Prepaid expenses and other current assets consisted of the following (in thousands):

Other long-term assets consisted of the following (in thousands):

Accounts payable and accrued liabilities consisted of the following (in thousands):

7. Intangible assets, net

As described in Note 10 – In-Licensing and Supply, under the Aegis Agreement the Company capitalized a $2.5 million milestone payment in August 2024 and a $5.0 million milestone payment in September 2024. The assets are amortized on a straight-line basis over the estimated life of the intellectual property of 14.5 years, beginning from the first commercial sale ofneffyin September 2024.

Intangible assets, net, all of which are finite-lived, consisted of the following (in thousands):

The amortization expense for the three months ended March 31, 2025 was$0.1 million. No intangible assets were held as of March 31, 2024, and there wasno amortization expense recognized for thethree months ended March 31, 2024.

As of March 31, 2025, estimated future amortization expense for capitalized intangible assets for the next five years is as follows (in thousands):

8. Collaboration and Out-Licensing

The Company has entered into collaboration and licensing agreements, including supply and distribution, to license certain rights toneffyto third parties. The terms of these arrangements typically include payment to the Company of one or more of the following: non-refundable, upfront license fees; clinical, regulatory, and/or commercial milestone payments; payment for clinical and commercial supply; and royalties or a transfer price on the net sales of licensed products.

Licenses of Intellectual Property. If the license to the Company’s intellectual property is determined to be distinct from the other performance obligations identified in the arrangement, revenue is recognized from non-refundable, upfront payments allocated to the license when the license is transferred to the customer and the customer is able to use and benefit from the license. If the license is subject to repurchase by the Company, at its option, control of the license is not considered transferred to the customer, and in such case, the Company would account for the proceeds allocated to such license as either a financing obligation or a lease in accordance with ASC 606. Future amounts received related to the license which is subject to the Company’s repurchase would be accounted for as additional financing proceeds and would increase the financing obligation on the Company’s condensed consolidated balance sheet. The Company would record such financing obligation as revenue when the right to repurchase has lapsed or was exercised.

If the license is not a distinct performance obligation, the Company evaluates the combined performance obligation to determine whether the combined performance obligation is satisfied over time or at a point in time and, if over time, the appropriate method of measuring progress for purposes of recognizing revenue from non-refundable, upfront fees. The Company evaluates the measure of progress each reporting period and, if necessary, adjusts the measure of performance and related revenue recognition.

Milestone Payments. At the inception of each arrangement that includes clinical, regulatory or commercial milestone payments, the Company evaluates whether achieving the milestones is considered probable and estimates the amount to be included in the transaction price using the most likely amount method. If it is probable that a significant revenue reversal would not occur, the value of the associated milestone is included in the transaction price. Milestone payments that are not within the Company’s control, such as approvals from regulators or where attainment of the specified event is dependent on the development activities of a third party, are not considered probable of being achieved until those approvals are received or the specified event occurs. Revenue is recognized when the underlying performance obligation has been met.

Transaction Price Allocation. At the inception of each arrangement, the Company identifies its distinct performance obligations and allocates the transaction price to the performance obligations based upon their relative standalone selling prices. Standalone selling price is the price at which an entity would sell a promised good or service separately to a customer. The best evidence of standalone selling price is an observable price of a good or service when sold separately by an entity in similar circumstances to similar customers. Since the Company typically does not have such evidence, the Company estimates standalone selling price so that the amount that is allocated to each performance obligation equals the amount that the Company expects to receive for transferring the promised goods or services. The methods that the Company uses to make such estimates include (1) the adjusted market assessment approach, under which the Company forecasts product sales in the appropriate market, considers probability of commercialization success, and estimates discount rates; and (2) the expected cost of satisfying the performance obligations inclusive of a reasonable margin, also known as the expected cost plus margin approach.

Research and Development Revenues. For arrangements that contain research and development commitments, any arrangement consideration allocated to the research and development work is recognized as the underlying services are performed over the research and development term, if the criteria for over time recognition are met. If the over time recognition criteria are not met, research and development performance obligations are recognized at a point in time, when the research and development work is completed.

Clinical and Commercial Supply. Arrangements that include a promise for the future supply of drug product for either clinical development or commercial supply at the licensee’s discretion are generally considered customer options. The Company assesses if these options provide a material right to the licensee and if so, they are accounted for as separate performance obligations.

Royalty/Transfer Price Revenues. For arrangements that include sales-based royalties or transfer price, including milestone payments based on the level of sales, and the license is deemed to be the predominant item to which the royalties relate, the Company recognizes revenue at the later of (i) when the related sales occur, or (ii) when the performance obligation to which some or all of the royalty has been allocated has been satisfied (or partially satisfied). The Company has not received any royalty or transfer price revenues as of March 31, 2025.

Alfresa Agreement

In March 2020, the Company signed a Letter of Intent (“LOI”) with Alfresa Pharma Corporation (“Alfresa”) for the right to negotiate a definitive agreement for the exclusive license and sublicensable right to develop, register, import, manufacture and commercialize neffyin Japan in exchange for an upfront payment of $2.0 million. In April 2020, the Company entered into a Collaboration and License Agreement for the rights pursuant to the LOI. Under the agreement, the Company delivered a license toneffy technology, completed a required clinical study, and remains obligated to use commercially reasonable efforts to develop and commercialize neffy in Japan. The parties agreed to share the cost of any additional clinical studies required for approval ofneffyin Japan. Alfresa is solely responsible for regulatory and commercialization activities and may elect to assume responsibility for manufacturing and supplying drug product for commercial use in Japan. Either party may terminate the agreement for certain breaches of the agreement. Unless terminated earlier by either or both parties, the term of the agreement will continue until the later of (i) expiration of the last-to-expire patent in Japan; or (ii)10 years after the commercial sale ofneffyin Japan.

In addition to the $2.0 million received under the LOI, the Company was initially eligible to receive up to $13.0 million of milestone payments upon achievement of certain clinical and regulatory milestones. Further, the Company is eligible to receive a negotiable transfer price expected to be in the low double-digit percentage on net sales subject to the regulatory approval to commercialize neffyin Japan.

At the commencement of this collaboration, the Company identified the following performance obligations: the license forneffyand research and development services, both of which have been completed. The Company determined the initial transaction price to be $7.0 million, which includes a clinical milestone as it was deemed not probable of significant reversal at the inception of the agreement. Due to the uncertainty in the achievement of the regulatory and commercial milestones, the variable consideration associated with these future milestone payments has been fully constrained and is excluded from the transaction price until such time that the Company concludes that it is probable that a significant reversal of previously recognized revenue will not occur. These estimates will be reassessed at each reporting period. The transaction price was allocated to the performance obligations based on the estimated stand-alone selling price of each performance obligation.

In July 2020, the Company earned a $5.0 million milestone payment upon the completion of a clinical milestone in Japan. In November 2024, the Company earned a $6.0 million milestone payment upon the completion of a regulatory milestone in Japan. Of the $13.0 million in milestone payments that the company was eligible to earn, $11.0 million in milestone payments has been earned and a final $2.0 million regulatory milestone remains. For the three months ended March 31, 2025 and 2024, the Company recognizedno revenue related to the Alfresa Agreement. As of both March 31, 2025 and December 31, 2024, there wasno contract liability recorded for the final regulatory milestone.

Recordati Agreement

In September 2020, the Company entered into a License and Supply Agreement (the “Recordati Agreement”) with Recordati Ireland, Ltd. (“Recordati”) for the exclusive license and sublicensable right to develop, import, manufacture or have manufactured commercial product, file and hold regulatory approvals and commercialize neffyin Europe and certain European Free Trade Association, Russia/the Commonwealth of Independent States, Middle East and African countries (the “Recordati Territory”).

Under the terms of the Recordati Agreement, the Company received an upfront payment of $11.8 million and a regulatory milestone payment of $6.0 million during 2020.

At the commencement of this collaboration, the Company identified the following performance obligations: the license forneffyin the defined territory and the research and development services. The Company determined the initial transaction price to be the $11.8 million upfront payment. Due to the uncertainty in the achievement of all the developmental and commercial milestones, at inception of the contract, the variable consideration associated with future milestone payments was fully constrained and excluded from the transaction price until such time that the Company concludes that it is probable that a significant reversal of previously recognized revenue will not occur. The transaction price was allocated to the performance obligations based on the estimated stand-alone selling price of each performance obligation. In November 2020, the Company earned a regulatory milestone of $6.0 million.

On February 22, 2023, the Company and Recordati entered into a termination agreement (the “Recordati Termination Agreement”), pursuant to which, among other things, the Company and Recordati agreed to terminate the Recordati Agreement. Pursuant to the Recordati Termination Agreement, the Company reacquired all of the Recordati rights, paid Recordati a one-time upfront payment of €3.0 million ($3.3 million in U.S. dollars), and has agreed to pay additional payments upon achievement of certain milestones including: (i) an EMA regulatory milestone payment of €2.0 million, (ii) a milestone payment of €5.0 million upon first commercial sale of a Recordati Licensed Product in the Recordati Territory, and (iii) royalty payments of up to €5.0 million in the aggregate from sales of Recordati Licensed Product(s) in the Recordati Territory (collectively, the “Recordati Rights”).

The Company determined that the Recordati Rights at the time of entering into the Recordati Termination Agreement had no alternative future use and therefore recorded the €3.0 million upfront payment to Recordati as an IPR&D expense presented within research and development expense. The Recordati Termination Agreement ended the Company’s performance obligations pursuant to the Recordati Agreement and consequently the existing contract liability of $3.1 million previously received from Recordati was recorded against IPR&D expense presented within research and development expense in the accompanying condensed consolidated statements of operations and comprehensive income (loss). Accordingly, no revenue has been recognized subsequent to the Recordati Termination Agreement. In June 2024, the EMA regulatory milestone was met and a €2.0 million ($2.1 million in U.S. dollars) expense was recorded in research and development expense in the accompanying condensed consolidated statements of operations and comprehensive income (loss). The Company paid the EMA regulatory milestone to Recordati in July 2024.

Pediatrix Agreement

In March 2021, the Company entered into a Collaboration and Distribution Agreement with Pediatrix Therapeutics, Inc. (“Pediatrix”) for the exclusive license and sublicensable right to develop, import, manufacture or have manufactured commercial product, file and hold regulatory approvals and commercialize neffyin the People’s Republic of China, Taiwan, Macau, and Hong Kong. Under the agreement, Pediatrix is responsible, at its sole cost and expense, for all ongoing development work that is necessary for or otherwise supports regulatory approval in the defined territory, including all clinical trials, and activities related to post-approval commitments and commercialization tests. In addition, Pediatrix is responsible for commercialization activities and may elect to assume responsibility for manufacturing and supplying drug product for commercial use. The Company is responsible for the manufacturing of product for clinical studies as well as commercial supply, all at a negotiated transfer price. Either party may terminate the agreement for certain breaches of the agreement. Unless terminated earlier by either or both parties, the term of the agreement will continue as long as Pediatrix has commercial sales ofneffyin the region, or 10 years after the first commercial sale.

Under the terms of the agreement, the Company received an upfront payment of $3.0 million. In addition, the Company is eligible to receive up to $84.0 million of milestone payments upon achievement of certain regulatory and commercial sales milestones. The next eligible milestone is a $4.0 million regulatory milestone. Subject to regulatory approval, the Company will earn tiered royalties in the low double-digits on annual net sales in the region and will receive a per unit supply price for the sale of commercial supply to Pediatrix.

At the commencement of this collaboration, the Company identified performance obligations related to the delivery of the license forneffyin the defined territory and manufacturing of product for clinical studies and commercial supply. The Company concluded that the license was distinct from potential supply obligation. The supply provisions are effectively options granted to Pediatrix to purchase future goods and did not contain a material right. The Company determined the initial transaction price to be the $3.0 million upfront payment. Due to the uncertainty in the achievement of all the developmental and commercial milestones, the variable consideration associated with these future milestone payments has been fully constrained and is excluded from the transaction price until such time that the Company concludes that it is probable that a significant reversal of previously recognized revenue will not occur. These estimates will be reassessed at each reporting period. The Company recognized revenue of the full $3.0 million during the year ended December 31, 2021.

Seqirus Agreement

In March 2024, the Company entered into a License and Distribution Agreement (the “Seqirus Agreement”) with Seqirus Pty, Ltd. (“Seqirus”) for the exclusive license to commercialize neffyin Australia and New Zealand (the “Seqirus Territory”). Under the Seqirus Agreement, the Company is responsible for the transfer of know-how, which includes regulatory materials, regulatory data, and commercialization data, and also for the manufacturing of product for commercial supply which is available to Seqirus at a negotiated price. Seqirus is solely responsible for all regulatory and commercialization activities in the Seqirus Territory. Either party may terminate the Seqirus Agreement for certain breaches. Unless terminated earlier by either or both parties, the initial term of the Seqirus Agreement is 15 years from the first commercial sale ofneffy in the Seqirus Territory. The Seqirus Agreement will automatically renew for two-year periods unless either party gives a notice to terminate at least 12 months prior to the end of the initial or any renewal term.

Under the terms of the Seqirus Agreement, the Company received an upfront payment of $0.5 million in May 2024. In addition, the Company was eligible to receive up to $4.5 million of milestone payments upon achievement of certain event milestones. Subject to regulatory approval in Australia and New Zealand, the Company will also receive a per unit supply price for the sale of commercial supply to Seqirus.

At the commencement of this collaboration, the Company identified one performance obligation which is the delivery of the license forneffyin the Seqirus Territory in combination with the transfer of know-how. The Company determined that the option to purchase the commercial supply does not represent a material right. The Company determined the initial transaction price to be the $0.5 million upfront payment. Due to the uncertainty in the achievement of all the regulatory milestones, the variable consideration associated with these future milestone payments has been fully constrained and is excluded from the transaction price until such time that the Company concludes that it is probable that a significant reversal of previously recognized revenue will not occur. The variable consideration will be reassessed at each reporting period. In May 2024, the Company delivered the license forneffyin the Seqirus Territory in combination with the transfer of know-how and recognized $0.5 million in revenue. In August 2024, the first milestone event was met and the Company recognized $1.5 million in revenue.

ALK Collaboration Agreement

In November 2024, the Company entered into a Collaboration, License and Distribution Agreement (the “ALK Collaboration Agreement”) with ALK-Abelló A/S (“ALK”). Pursuant to the ALK Collaboration Agreement, the Company granted to ALK a worldwide (other than the United States, Japan, mainland China, Hong Kong, Taiwan, Macau, Australia and New Zealand) (“ALK Territory”), exclusive license under certain of the Company’s patents and know-how to develop, manufacture and commercialize products containing epinephrine administered intranasally, including EURneffy(the trade name forneffyin the European Union) (epinephrine nasal spray) (“Products”), for all human uses, including the immediate or emergency treatment of allergic reactions (including Type I) and anaphylaxis and urticaria, and other future indications as agreed by the parties. If the Company develops any new intranasally administered product that contains epinephrine and files a new drug application in the United States for such product (“New Product”), upon ALK’s request such New Product will be included as a Product under the ALK Collaboration Agreement, subject to ALK bearing the costs of development of such New Product for its licensed territory.

Under the ALK Collaboration Agreement, the Company is obligated to transfer to ALK the existing marketing authorizations for the Products in ALK’s territory. The Company is also required to conduct certain development and regulatory activities for Products in support of obtaining further regulatory approval of Products in ALK’s territory and will transfer such regulatory approvals to ALK. ALK is obligated to use commercially reasonable efforts to obtain and maintain regulatory approval for Products through the European Commission and within specified countries within ALK’s territory. Following such approval for a Product in each indication within specified countries within ALK’s territory, ALK is obligated to use commercially reasonable efforts to commercialize such Product in such indication in such countries and to achieve first commercial sale of a Product in certain countries in accordance with a timeline specified in the ALK Collaboration Agreement.

Under the ALK Collaboration Agreement, ALK made a $145.0 million upfront payment to the Company in November 2024. The Company is eligible to receive regulatory and commercialization milestones of up to $20.0 million and sales-based milestones of up to $300.0 million, provided that $55.0 million of such sales-based milestones are contingent upon the Company obtaining regulatory approval for the Product in Canada by a specified time. The Company is entitled to receive tiered royalty payments on net sales in the mid- to high-teens, subject to certain standard reductions and offsets. Royalties will be payable, on a Product-by-Product and country-by-country basis, until the latest of the expiration of the licensed patents covering such Product in such country,15 years from first commercial sale of such Product in such country, or expiration of regulatory exclusivity for such Product in such country.

The contract will expire upon the expiration of the last to expire royalty term for all Products in the ALK Territory, unless terminated earlier. Either the Company or ALK may terminate the ALK Collaboration Agreement in the case of the other party’s insolvency or in the event of an uncured material breach of the other party, except that the Company may not terminate the ALK Collaboration Agreement for ALK’s material breach of its commercial diligence obligations. ALK may terminate the ALK Collaboration Agreement for convenience upon 12 months’ prior written notice or for a safety or regulatory concern. The Company may terminate the ALK Collaboration Agreement in the event ALK makes certain challenges to certain of the Company’s patents. Prior to a change of control and outside of a set period of time after which the Company commences change of control negotiations, the Company may terminate the ALK Collaboration Agreement with respect to all countries in the European Economic Area (“EEA”) upon prior written notice to ALK and payment of a termination fee that is the higher of an agreed mid-nine digit amount and the fair market value of the Products business in the EEA at the time of such termination (the “Repurchase Option”). The Company may also terminate the ALK Collaboration Agreement if ALK commercializes a non-injectable epinephrine product or manufactures such a product in the United States.

In connection with the ALK Collaboration Agreement, the Company and ALK also entered into a commercial supply agreement (the “ALK Supply Agreement”) in November 2024, under which the Company will supply ALK’s requirements (and ALK will purchase from the Company its requirements) of Products forfive years for a specified supply price, after which ALK may elect to transition to itself or its contract manufacturer the manufacture and supply of Products. The contract term for the ALK Supply Agreement is coterminous with the ALK Collaboration Agreement. Either the Company or ALK may terminate the ALK Supply Agreement in the event of an uncured material breach of the other party.

Accounting Assessment

The Company concluded that the ALK Collaboration Agreement and the ALK Supply Agreement qualify as a contract with a customer under ASC 606 as one combined arrangement. The Company identified the following performance obligations: (i) exclusive commercialization license in the European Economic Area (the “EEA License”); (ii) exclusive commercialization license in the rest of the ALK Territory (the “ROW License”) and; (iii) five separate development and regulatory services performance obligations. The Company also evaluated the (i) promise to add a New Product and new indications to the ALK Collaboration Agreement, and (ii) the promises under the ALK Supply Agreement, and concluded that these promises did not meet the definition of a performance obligation nor did these promises convey a material right to ALK.

The Company determined that the non-refundable upfront payment of $145.0 million is the estimated transaction price at contract inception. The outstanding regulatory milestone payments (totaling $15.0 million) were fully constrained at contract inception and as of March 31, 2025 as a result of the uncertainty of whether any of the milestones will be achieved. In making the assessment of the constraint utilizing the most likely amount method, the Company considered the stage of development, and the risks associated with the remaining development required to achieve the milestones, as well as whether the achievement of the milestone is outside the control of the Company or ALK. The Company has determined that the commercial milestone ($5.0 million) and the sales-based milestones and royalties will be recognized on the later of when the related sales occur or when control of the associated license has been transferred, as the Company determined that such sales-based consideration relates predominantly to the licenses granted to ALK. The Company reevaluates the transaction price at the end of each reporting period and as uncertain events are resolved or other changes in circumstances occur and will include regulatory milestones in the transaction price if it is probable that a significant revenue reversal will not occur in future periods.

At contract inception, the Company determined the estimated standalone selling prices for each performance obligation in order to allocate the transaction price among the performance obligations. The standalone selling price for the licenses was estimated using the adjusted market assessment approach. Under this method, the Company forecasted future cash flows expected in the ALK Territory, the probability of commercialization success, and a market discount rate. To estimate the standalone selling prices of the development and regulatory services, the Company forecasted its expected costs of satisfying each performance obligation inclusive of an appropriate margin for that service.

The Company allocated the total transaction price to each performance obligation on a relative standalone selling price basis and determined whether revenue should be recognized at a point in time or over time. The Company allocated $69.4 million to the EEA License performance obligation; $73.1 million to the ROW License performance obligation; and $2.6 million to the development and regulatory services performance obligations.

Revenue should be recognized when, or as, an entity satisfies a performance obligation by transferring a promised good or service to a customer, i.e., when the customer obtains control of the good or service. The licenses granted to ALK are being accounted for as distinct performance obligations. The licenses relate to functional intellectual property for which revenue is recognized at a point in time. In the case of the EEA License, the Company evaluated the impact of the Company’s Repurchase Option, and determined that, as a result of the Company’s ability to repurchase the license, control of the EEA License has not been transferred to ALK under ASC 606. The Company determined that the transaction price allocated to the EEA License should be accounted for as a financing liability, due to the repurchase price being greater than the original selling price of this performance obligation. Control of the EEA License will not be considered transferred to ALK until such time that the Repurchase Option lapses, which under the terms of the ALK Collaboration Agreement, will occur upon the expiration of the contract, or exercise by the Company of the Repurchase Option. In November 2024, the Company recognized the transaction price allocated to the EEA License of $69.4 million as a financing liability.

In the case of the ROW License, the point in time for recognition of revenue was shortly after the inception of the contract because the customer obtained control of the license and was able to use and benefit from its right to use the intellectual property at that point. In November 2024, the Company recognized $73.1 million in revenue for the transaction price allocated to the ROW License.

The development and regulatory services performance obligations under the ALK Collaboration Agreement each represent a separate performance obligation. The development and regulatory services, which are transferred to the customer over time, were provided to ALK from inception of the agreement and are expected to continue through 2028. Revenue related to the development and regulatory services performance obligations was initially recorded as contract liability and is being recognized as services are performed based on the costs incurred through the end of each reporting period, as a percentage of the estimated total costs to be incurred for these performance obligations. In November 2024, the Company recognized $0.5 million of revenue related to the development and regulatory services performance obligations. For thethree months ended March 31, 2025, the Company recognized$0.2 million of revenue related to the development and regulatory services performance obligations. As of March 31, 2025, the accompanying consolidated balance sheet includes a contract liability of$0.5 million classified as current and$1.3 million classified as noncurrent, associated with these performance obligations, based on the expected period of performance for the development and regulatory services.

9. Commitments and Contingencies

Leases

In October 2021, the Company entered into a 38-month noncancelable lease for its current headquarters location consisting of 4,047 rentable square feet of office space in San Diego, California. Under the terms of the agreement, there is no option to extend the lease, and the Company is subject to additional charges for common area maintenance and other costs. Monthly rental payments due under the lease commenced on December 6, 2021 and escalate through the lease term. The Company prepaid the first month’s rent upon execution of the lease, and the lease agreement provided full rent abatement for the second and third months of the rental term. As there was not an implicit rate within the lease, the discount rate was determined by using a set of peer companies incremental borrowing rates.

In January 2025, the Company entered into a lease amendment to its headquarters location lease (the “Headquarters Amendment”), pursuant to which the Company will relocate to a new premises located in the same building which consists of 9,254 rentable square feet of office space. The Company will take possession of the new office space when the landlord’s work is substantially complete, which is estimated to be July 1, 2025. The Company must vacate its current office space within 15 days of taking possession of the new premises. The term of the lease will be extended to 36 full calendar months following the date the Company takes possession of the new office space. As of March 31, 2025, the remaining lease term was three months, subject to the substantial completion of the new office space. The monthly lease payments will increase when the Company takes possession of the new space and escalate through the lease term, resulting in an annualized payment of $0.6 million. The Company remains subject to additional charges for common area maintenance and other costs. The Company has one option to extend the lease for an additional term ofthree years, and the monthly payment amounts would be determined by the landlord at the then-prevailing rate.

Upon entering into the Headquarters Amendment, the Company remeasured the right-of-use asset and lease liability pertaining to its current headquarters, and as a result recorded an additional $0.1 million to both its right-of-use asset and lease liability on its condensed consolidated balance sheet. As there was not an implicit rate within the lease amendment, a discount rate of 8% was determined using a set of peer companies’ incremental borrowing rates.

The following table summarizes supplemental lease information (in thousands):

(1)Variable lease costs for the three months ended March 31, 2025 and 2024 were immaterial.

As of March 31, 2025, future minimum non-cancelable operating lease payments are as follows (in thousands):

Contingencies

From time to time, the Company may be involved in various legal proceedings and subject to claims that arise in the ordinary course of business.

On July 24, 2023, Aera A/S, an IP consultancy firm in Denmark representing an unidentified opponent, filed a notice of opposition with the European Patent Office (the “EPO”) in respect of EP 3678649 (the “EP ‘649 Patent”), which is a patent directed to a nasal spray formulation of epinephrine, and uses thereof. The Company filed a response to the notice of opposition on December 15, 2023. The EPO scheduled oral proceedings on October 7, 2025, and the Company will continue to vigorously defend the EP ‘649 Patent. The results of any notice of opposition are inherently unpredictable and uncertain and could result in the EPO finding the patent to be invalid or unenforceable.

On March 25, 2025, Aptargroup, Inc. and Aptar France SAS (collectively, “Aptar”) filed a suit against ARS Pharmaceuticals, Inc. and ARS Pharmaceuticals Operations, Inc. in the United States District Court for the Southern District of New York. Aptar alleges the Company violated the Defend Trade Secrets Act (18 USC § 1836), misappropriated trade secrets under New York state law, and committed various breaches of contract. The complaint was served to the Company and the response is due on June 12, 2025. The Company intends to vigorously defend itself in this matter.

Regardless of the outcome, involvement in legal proceedings may have an adverse impact on the Company because of defense and settlement costs, diversion of management resources, and other factors. The Company cannot predict the outcome of these suits, and failure by the Company to obtain favorable resolutions could have a material adverse effect on its business, results of operations, and financial condition. The Company’s chances of success on the merits of these suits are still uncertain and any possible loss or range of loss cannot be reasonably estimated and as such the Company has not recorded a liability as of March 31, 2025.

Except as described above, there is no action, suit, proceeding, inquiry or investigation before or by any court, public board, government agency, self-regulatory organization or other body pending or, to the knowledge of the Company’s executive officers, threatened against or affecting the Company, the Company’s common stock, any of its subsidiaries or its subsidiaries’ officers or directors in their capacities as such, in which an adverse decision could have a material adverse effect.

Unconditional Purchase Obligations and Commitments

Unconditional purchase obligations and commitments are defined as agreements to purchase goods or services that are enforceable and legally binding (non-cancelable, or cancelable only in certain circumstances). In the normal course of business, the Company enters into arrangements with suppliers, manufacturers, and various other companies that supply goods or services. These arrangements can include unconditional purchase obligations and commitments.

The total amount of unconditional purchase obligations related to the supply of raw materials is$60.6 million as of March 31, 2025. Payment obligations by year are as follows: 2025 ($4.0 million), 2026 ($10.5 million), 2027 ($11.8 million), 2028 ($13.8 million), and$2.9 million per year thereafter through 2035. During the three months ended March 31, 2025, the Company made$4.3 million in payments under this agreement. No payments were made under this agreement during thethree months ended March 31, 2024.

The total amount of unconditional purchase obligations related to hosted software license subscription fees is$3.0 million as of March 31, 2025. Payments by year are as follows: 2025 ($1.1 million), 2026 ($1.5 million), and 2027 ($0.4 million). During the three months ended March 31, 2025, the Company made$0.3 million in payments under this agreement. No payments were made under this agreement during thethree months ended March 31, 2024.

The total amount of commitments related to a corporate sponsorship agreement with Food Allergy Research and Education, Inc. is$5.0 million as of March 31, 2025. Payments by year are as follows: 2025 ($2.0 million) and 2026 ($3.0 million). During the three months ended March 31, 2025, the Company made$2.0 million in payments under this agreement. No payments were made under this agreement during thethree months ended March 31, 2024.

The amounts above do not represent the entire anticipated spend in the future but represent only those items for which the Company is contractually obligated. For this reason, these amounts do not provide an indication of the Company’s expected future cash outflows related to purchases and commitments.

10. In-Licensing and Supply

License Agreement with Aegis

In June 2018, the Company entered into a License Agreement (the “Aegis Agreement”) with Aegis Therapeutics, LLC (“Aegis”). Under the Aegis Agreement, the Company licensed the exclusive, worldwide, royalty-bearing, sublicensable, rights to certain proprietary Aegis technology, patent rights and know-how to develop and commercialize epinephrine products. The Company utilizes this technology in its sole commercial product, neffy. As consideration for the license, the Company paid an upfront license fee of $50,000, which was recorded in research and development expenses in the condensed consolidated statement of operations.

The Company is required to make aggregate milestone payments of up to $20.0 million upon achievement of certain regulatory and commercial milestones. Regulatory milestone payments under the Aegis Agreement are recorded upon completion of the required events, as the triggering events are not considered to be probable until they are achieved. Prior to the FDA approval ofneffyin August 2024, regulatory milestone payments were recorded as research and development expenses in the condensed consolidated statement of operations. The Company made a $0.5 million milestone payment to Aegis upon the achievement of a regulatory milestone during 2019, and a $1.0 million milestone payment to Aegis upon the FDA’s acceptance of the Company’s new drug application submission forneffy, which occurred in the third quarter of 2022. Since the approval ofneffyin August 2024, regulatory milestone payments have been capitalized as intangible assets in the accompanying condensed consolidated balance sheets. Amortization expense has been recorded to cost of goods sold, in the accompanying condensed consolidated statements of operations and comprehensive income (loss), on a straight-line basis over the estimated life of the intellectual property of 14.5 years. In August 2024, a $2.5 million milestone was met for achieving FDA approval ofneffy. In September 2024, a $5.0 million milestone was met for the first commercial sale ofneffy. As a result, the Company capitalized $7.5 million as intangible assets in the accompanying condensed consolidated balance sheets in the third quarter of 2024. The Company paid the $2.5 million milestone for achieving FDA approval ofneffyin September 2024 and paid the $5.0 million milestone for the first commercial sale ofneffyin October 2024.

Stock Options

Stock options granted under the Company’s equity incentive plans expire no later than 10 years from the date of grant and generally vest over a four-year period, with vesting either occurring at a rate of 25% at the end of the first year and thereafter in 36 equal monthly installments or on a monthly basis. In the case of awards granted to the Company’s non-employee board members, vesting generally occurs on a monthly basis over three years or in full on an annual basis. The Company issues new shares of common stock upon the exercise of stock options.

A summary of the Company’s stock option activity for thethree months ended March 31, 2025 is as follows:

The exercisable shares subject to options outstanding at March 31, 2025 in the table above include vested and early exercisable awards. The aggregate intrinsic value in the table above is calculated as the difference between the exercise price of the underlying options and the estimated fair value of the Company’s common stock for all options that were in-the-money at March 31, 2025. The aggregate intrinsic value of options exercised during the three months ended March 31, 2025 and 2024 was$1.3 million and$1.0 million, respectively.

The weighted-average grant date fair value per share of option grants for the three months ended March 31, 2025 and 2024 was$8.06 and$4.36, respectively. The total fair value of shares vested during the three months ended March 31, 2025 and 2024 was$6.2 million and$6.0 million, respectively.

The fair value of stock options granted was estimated using a Black-Scholes option-pricing model (“Black-Scholes”) with the following weighted-average assumptions:

The fair value of stock options was determined using the Black-Scholes assumptions below. Each of these inputs is subjective and generally requires significant judgment.

Fair Value of Common Stock. The fair market value of the Company's common stock is based on its closing price as reported on the date of grant on the primary stock exchange on which the Company’s common stock is traded.

Expected Term. The expected term represents the period that the options granted are expected to be outstanding. The expected term of stock options issued is determined using the simplified method (based on the mid-point between the vesting date and the end of the contractual term) as the Company has concluded that its stock option exercise history does not provide a reasonable basis upon which to estimate expected term.

Expected Volatility. Given the Company’s limited historical stock price volatility data, the Company derived the expected volatility from the average historical volatilities over a period approximately equal to the expected term of comparable publicly traded companies within its peer group that were deemed to be representative of future stock price trends as the Company has limited trading history for its common stock. 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 rate, with maturities similar to the expected term of the stock options.

Expected Dividend Yield. The Company has never paid dividends on its common stock and does not anticipate paying any dividends in the foreseeable future. Therefore, the Company uses an expected dividend yield of zero.

13. Employee Benefit Plans
