ARS Pharmaceuticals, Inc. Revenue Disclosure

Revenue Recognition

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.

Product revenue, net

The Company’s product, neffy, was approved by the FDA in August 2024, and the Company began generating product revenue from sales of neffy in September 2024. The Company sells its product to its wholesale distributor and pharmacy customers in the United States. These customers subsequently resell the products to pharmacies and health care providers or dispense products directly to patients.

The Company uses a third-party logistics provider to support the warehousing, distribution, order processing, accounts receivable, and data management. From September 2024 to July 2025, the Company operated under a title model agreement (the “Title Agreement”), pursuant to which an affiliate of third-party logistics provider (the “Title Agent”) purchased and took title of the Company’s product, then resold it to the Company’s customers. Beginning in August 2025, the Company discontinued the Title Agreement and now sells its products directly to customers. In accordance with ASC 606, the Company recognizes revenue at a point in time when the customers obtain control of the Company’s products, typically upon delivery.

The Company also enters into consignment agreements with certain pharmacies, under which revenue is recognized when the product is sold to a patient and control transfers from the Company to the patient. Consignment agreements were not subject to the Title Agreement.

Product revenue is recorded at the net transaction price, which includes estimates for variable consideration such as distribution service fees, prompt pay discounts, product returns, chargebacks, rebates, co-payment assistance, and other incentives for certain indirect customers. The Company establishes reserves for these estimates based on amounts earned or expected to be claimed on related sales. Reserves are recorded as a reduction to accounts receivable if payable to a customer or as an accrued expense if payable to a third-party or related to product returns.

The Company uses the expected value method to determine the appropriate amount of variable consideration, considering factors such as contractual and statutory requirements, known market events, industry trends and data, forecasted customer buying and payment patterns, and historical actual data. Estimates are reassessed each reporting period, and adjustments are recorded on a cumulative catch-up basis, which would affect product revenue and net (loss) income in the period of adjustment. Variable consideration is included in net product revenue only to the extent it is probable that a significant revenue reversal will not occur in a future period.

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 accompanying 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 amount purchased. These discounts are recorded as contra trade accounts receivable on the accompanying 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 accompanying 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 costs associated with the revenue recognized for product that remains in the distribution channel and any chargeback amounts not invoiced to the Company at the end of each reporting period. Estimated chargebacks are recorded as contra trade accounts receivable on the accompanying 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 of rebates based on the expected number of claims and the related costs associated with the revenue recognized for product that remains in the distribution channel and any rebate amounts for product that has been dispensed to a patient but not invoiced to the Company at the end of each reporting period. Rebate estimates are recorded as other current liabilities on the accompanying 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 recognized for products that remain in the distribution channel and any co-payment assistance amounts not invoiced to the Company at the end of each reporting period. Co-payment programs estimates are recorded as other current liabilities on the accompanying 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. neffy was commercially launched in September 2024 and due to the limited returns data, the Company uses professional judgment and industry data to estimate returns. As time passes and additional historical sales and returns data becomes available, the Company will update the estimated returns as needed. A reserve for potential product returns is recorded as other current liabilities on the accompanying consolidated balance sheets.

Revenue under collaboration and supply agreements

The Company enters into collaboration agreements to license certain rights to neffy to third parties and supply neffy for distribution. At contract inception, the Company evaluates whether the collaboration agreement involves joint operating activities in which the parties are active participants and share significant risks and rewards in accordance with ASC Topic 808, Collaborative Agreements (“ASC 808”). Arrangements that meet these criteria are accounted for as collaborative arrangements under ASC 808. This assessment is updated over the life of the arrangement as roles and responsibilities change.

For collaboration agreements within the scope of ASC 808 that include multiple components, the Company determines which components are accounted for under ASC 808 and which components represent vendor-customer relationships accounted for under ASC 606. For components accounted for under ASC 808, the Company applies a consistent recognition approach based on applicable accounting guidance or a reasonable policy election. Amounts due from or payable to collaboration partners are presented in the income statement based on the nature of the underlying activity. When the Company is the principal in sales to third parties, revenues, cost of goods sold, and operating expenses are recorded on a gross basis. When the Company is not the principal, its share of results is recorded on a net basis as collaboration revenue or expense.

If the Company concludes that some or all components of the agreement are distinct and represent a transactions with a customer, the Company accounts for those elements of the arrangement in accordance with ASC 606 by applying the five-step model described above.

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, such as royalties or milestone payments, would be accounted for as additional financing proceeds and would increase the financing obligation in the accompanying 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. In making the assessment of the constraint, the Company considers several factors, such as the stage of product development, the risks associated with the remaining activities required to achieve the milestones, as well as whether the achievement of the milestone is outside the control of the Company. 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. Revenue from product sales to the Company’s collaboration partners is recognized at the point-in-time that the collaboration partner obtains control, which is typically based upon the terms of delivery of the product.

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).
