Current report
Research and development expenses increased primarily due to the $6.0 million payment for the licensing agreement that we entered into with Anji in the third quarter of 2025. Additionally, we had an increase in clinical trial expense, primarily for our insulin and inhalation pipeline products, as well as an increase in depreciation expense. This was partially offset by a decrease in material and supply expenses.

Cash Flows
Current report
In November 2024, the FASB issued ASU 2024-04,Debt– Debt with Conversion and Other Options, (subtopic 470-20). The update is intended to improve the relevance and consistency in application of the induced conversion guidance in Subtopic 470-20 for (a) convertible debt instruments with cash conversion features and (b) debt instruments that are not currently convertible. ASU 2024-04 is effective for annual reporting periods beginning after December 15, 2025. We are currently evaluating the impact of the new standard on our consolidated financial statements and related disclosures.
Current report
In September 2025, the FASB issued ASU 2025-06,Intangibles - Goodwill and Other-Internal-Use Software (Subtopic 350-40): Targeted Improvements to the Accounting for Internal-Use Software. The ASU amends the existing standard to remove all references to prescriptive and sequential software development project stages. Under this guidance, eligible software development costs will begin to be capitalized when management has authorized and committed to funding the software project, and it is probable that the project will be completed and the software will be used to perform the function intended. In evaluating whether it is probable the project will be completed; management is required to consider whether there is significant uncertainty associated with the development activities of the software. This guidance is effective for all annual periods beginning after December 15, 2027, and for interim periods within those annual reporting periods, with early adoption permitted. The guidance may be applied on a prospective basis, a modified basis for in-process projects, or a retrospective basis. We are currently evaluating the impact of the new standard on our consolidated financial statements and related disclosures.

BAQSIMI® Acquisition
Previous report
In connection with the acquisition of BAQSIMI® in June 2023, we entered into a Transition Service Agreement, or TSA, with Lilly pursuant to which Lilly agreed, for a period of time not to exceed 18 months to provide certain services to us to support the transition of the BAQSIMI® operations, including with respect to the conduct of certain clinical, regulatory, medical affairs, and commercial sales channel activities. Revenues from the sales of BAQSIMI® under the TSA with Lilly during the transition period were recognized on a net basis, similar to a royalty arrangement. The impact of this revenue recognition method resulted in lower reported revenues relative to the revenue that would have been reported had we recognized gross revenues from sales of BAQSIMI®.
Previous report
Throughout 2024, we assumed distribution responsibilities from Lilly on a country-by-country basis and once the marketing authorizations for each territory were transferred to us, we entered into distribution agreements, and obtained sufficient quantities of Amphastar labeled inventory. As we assumed distribution responsibilities in each country, we started recognizing gross revenues and cost of revenues from the sales of BAQSIMI®, which is classified as product revenue, net and cost of revenue, respectively on the consolidated statement of operations. As of January 1, 2025, the TSA has been completed and we distribute and manage the BAQSIMI® supply chain in all countries where it is available.
Previous report
In connection with the acquisition, we also entered into a Manufacturing Service Agreement, or MSA, with Lilly, pursuant to which Lilly agreed, for a period of time not to exceed 18 months, to provide certain manufacturing, packaging, labeling, and supply services for BAQSIMI® directly through third-party contractors to us in connection with our operation of the development, manufacture, and commercialization of BAQSIMI®. The MSA expired in December 2024 and as part of the agreement, we were obligated to purchase all API, components, and finished goods from Lilly at prices agreed upon in the MSA.
Previous report
During the fourth quarter of 2024, we executed new agreements with CMOs, for the supply and packaging of BAQSIMI®, and entered into an agreement to purchase approximately $34.0 million of API, components and finished goods inventories on hand from Lilly.
Previous report
For more information regarding our acquisition of BAQSIMI®, see “Part II – Item 8. Financial Statements and Supplementary Data – Notes to Consolidated Financial Statements – Note 3. BAQSIMI® Acquisition.”
Previous report
We previously operated as two reportable segments, Finished pharmaceutical products and APIs. However, as a result of the BAQSIMI® acquisition, including the expiration of the MSA, and TSA in the fourth quarter of 2024, the level of detail at which our chief operating decision maker, or CODM, regularly reviews and manages the business has changed, resulting in a change from two reportable segments to one segment, pharmaceutical products.
Previous report
Information reported herein is consistent with how it is reviewed and evaluated by our CODM.
Previous report
Throughout 2024, we assumed distribution responsibilities for BAQSIMI®from Lilly to our customers in the United States, and certain other countries. As a result, $126.9 million of our BAQSIMI®sales for the year ended December 31, 2024, were recognized as product revenues, net, similar to our other products.
Previous report
For more information, see “Part II – Item 8. Financial Statements and Supplementary Data – Notes to Consolidated Financial Statements – Note 4. Revenue Recognition.”
Previous report
The decrease in gross margins during the year ended December 31, 2024, is primarily a result of the TSA with Lilly. The portion of revenues relating to BAQSIMI®sales made by Lilly on our behalf are reported on a net basis, similar to a royalty arrangement with no amount reported as cost of revenues. Therefore, in the prior year, BAQSIMI®sales did not have any associated cost of revenues, which increased the gross margins. Additional factors contributing to the decrease in gross margins during the year include an increase in depreciation and amortization expenses related to the acquired BAQSIMI®assets, as well as increases in labor costs and the cost for certain APIs and purchased components.
Previous report
Research and development expenses remained flat during the year. There was an increase in salary and personnel-related expenses, as well as an increase in FDA filing fees as we filed the ANDA for AMP-018 in 2024. These increases were offset by a decrease in clinical trials expense, as well as a decrease in materials and supplies expense, as a result of a ramp-up of expenses in 2023 for our insulin and inhalation pipeline products.

Inventories
Previous report
Inventories consist of currently marketed products and products manufactured under contract. Inventories are stated using the first-in, first-out method, on a consistent basis. Inventory is stated at the lower of cost or net realizable value. We adjust inventories to their net realizable value: (i) if a launch of a new product is delayed and inventory may not be fully utilized and could be subject to impairment, (ii) when a product is close to expiration and not expected to be sold, (iii) when a product has reached its expiration date, (iv) when a product is not expected to be sellable, and (v) when the estimated net realizable value is below cost. In determining the estimated net realizable value of an inventory item, we consider factors such as the forecasted average net selling price, the amount of inventory on hand, its remaining shelf life, its regulatory approval status, and current and expected market conditions, including management forecasts and levels of competition.
Previous report
The largest adjustment to the net realizable value of our inventory has historically been related to enoxaparin. The adjustment of enoxaparin inventory to its net realizable value has been driven primarily by increases in the prices of heparin, the starting material for the production of the API in our enoxaparin product. Other cost increases relate to labor and overhead also impacted the cost of producing enoxaparin. Additionally, fluctuations in the forecasted average net selling price impact this estimate. The average net selling price has fluctuated due to competitor entries and exits from the market.

Impairment of Intangible and Long-Lived Assets
Previous report
We review long-lived assets and definite-lived identifiable intangible assets or asset groups for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Such events and circumstances include decisions by the FDA regarding evidence of effectiveness of proprietary drug candidates or bioequivalence (sameness) of our generic product candidates as compared to the reference drug, communication with the regulatory agencies regarding the safety and efficacy of our products under review, the use of the asset in current research and development projects, any potential alternative uses of the asset in other research and development projects in the short-to-medium term, clinical trial results and research and development portfolio management options. Determination of recoverability is based on an estimate of undiscounted future cash flows resulting from the use of the asset or asset groups and its eventual disposition. If the sum of the expected future undiscounted cash flows is less than
Previous report
the carrying amount of the asset or asset groups, further impairment analysis is performed. An impairment loss is measured as the amount by which the carrying amount exceeds the fair value of the asset or asset groups (assets to be held and used) or fair value less cost to sell (assets to be disposed of). All of our impairments relate primarily to the isolated write-off of certain manufacturing equipment related to abandoned projects. Since we periodically assess our product candidates and make changes to product development plans, we incur impairment charges from time to time which can fluctuate significantly from period to period.
Previous report
The indefinite-lived intangible asset, the Primatene® trademark acquired in June 2008, and goodwill are tested for impairment annually, in the fourth quarter, or more frequently if indicators of impairment are present. An impairment loss is recorded if the asset’s fair value is less than its carrying value. We also periodically review the Primatene® trademark to determine if events and circumstances continue to support an indefinite useful life. When we choose to perform a qualitative assessment, we evaluate economic, industry and company-specific factors as an initial step. If we determine it is more likely than not that the Primatene® trademark is impaired or the fair value of a reporting unit is less than its carrying amount, further quantitative impairment process is then performed; otherwise, no further testing is required. If the life is no longer indefinite, the asset is tested for impairment, and the carrying value, after recognition of any impairment loss, is amortized over its remaining useful life.
Previous report
We acquired the BAQSIMI® product rights in June 2023. BAQSIMI® is an emergency nasal spray used to treat severe hypoglycemia. The BAQSIMI® product rights intangible asset is amortized over its estimated useful life of 24 years. In determining the BAQSIMI® product rights’ useful life, we considered the following: the expected use of the intangible asset; the longevity of the brand; the legal, regulatory and contractual provisions that affect their maximum useful life; our ability to renew or extend the asset’s legal or contractual life without substantial costs; effects of the regulatory environment; expected changes in distribution channels; maintenance expenditures required to obtain the expected future cash flows from the asset; and considerations for obsolescence, demand, competition and other economic factors.
Previous report
No impairment of indefinite-lived intangible asset and goodwill was recorded during the years ended December 31, 2024 and 2022. For the year ended December 31, 2023, we recorded an impairment charge of $2.7 million related to our IMS (UK) international product rights, as we decided to delay the launch of the IMS UK products indefinitely. We recorded the impairment in the cost of revenue line in our consolidated statement of operations.
Previous report
Deferred Income Taxes
Previous report
We utilize the liability method of accounting for income taxes under which deferred taxes are determined based on the temporary differences between the financial statements and the tax basis of assets and liabilities using enacted tax rates. A valuation allowance is recorded when it is more likely than not that the deferred tax assets will not be realized.
Previous report
A number of years may elapse before an uncertain tax position for which we have established a tax reserve is audited and finally resolved. The number of years for which we can be subject to audit varies depending on the tax jurisdiction. While it is often difficult to predict the final outcome or the timing of the resolution of an audit, we believe that our reserves for uncertain tax benefits reflect the outcome of tax positions that is more likely than not to occur. The resolution of a matter could be recognized as an adjustment to our provision for income taxes and our effective tax rate in the period of resolution, and may also require a use of cash.

Share-Based Compensation
Previous report
Options issued under our amended and restated 2015 Equity Incentive Award Plan, or the Amended 2015 Plan, 2015 Equity Incentive Award Plan, or the Original 2015 Plan, and our amended and restated 2005 Equity Incentive Award Plan, or 2005 Plan, are granted at exercise prices equal to or greater than the fair value of the underlying common shares on the date of grant and vest based on continuous service. There have been no awards with performance conditions and no awards with market conditions. The options have a contractual term of five to ten years and generally vest over a three- to five-year period.
Previous report
We use the Black-Scholes option pricing model to determine the fair value of options awards. The Black-Scholes option pricing model has various inputs such as the common share price on the date of grant, exercise price, the risk-free interest rate, volatility, expected life and dividend yield, all of which are estimates. We used the risk-free rate on U.S. Treasury securities at the time of grant for instruments with maturities commensurate with the expected term of the stock option. Our volatility estimate was based on the weighted average historical volatility of our stock price since IPO. Our
Previous report
dividend yield was assumed to be 0%, because we have no plans to pay dividends. We estimate the expected term of options with consideration of vesting date, contractual term, and historical experience for employee exercise and post-vesting employment termination behavior after our common stock has been publicly traded. The expected term of “plain vanilla” options is estimated based on the midpoint between the vesting date and the end of the contractual term under the simplified method.
Previous report
The fair value of each share-based compensation award is amortized into compensation expense on a straight-line basis between the grant date for the option and the vesting date net of expected forfeitures. We estimate forfeitures at the time of grant and revise those estimates in subsequent periods if actual numbers differ from such estimates. The change of any of these inputs could significantly impact the determination of the fair value of our options as well as significantly impact our results of operations.
Previous report
In November 2023, the Financial Accounting Standards Board, or FASB, issued Accounting Standard Update 2023-07,Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures which is intended to improve reportable segment disclosure requirements, primarily through additional disclosures about significant segment expenses. The standard is effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024, with early adoption permitted. The amendments should be applied retrospectively to all prior periods presented in the financial statements. The adoption of this guidance did not have a material impact on our consolidated financial statements and related disclosures.

Current wording
The increase in product revenues, net, for 2025 was primarily due to the following changes:
Previous wording
Primatene MIST® sales increased primarily due to an increase in unit volumes. The increase in sales of epinephrine was primarily due to an increase in unit volumes as we began selling our epinephrine pre-filled syringes in Canada starting in the third quarter of 2024. The decrease in sales of glucagon was primarily due to a decrease in unit volumes, as a result of competition and a move to ready to use glucagon products such as BAQSIMI®. The decrease in sales of enoxaparin and naloxone was primarily due to a decrease in unit volumes. The decrease in other products was primarily due to lower unit sales of atropine and calcium chloride, as a result of other suppliers returning to their historical distribution levels, as well as lower unit sales of medroxyprogesterone, as our API supplier discontinued making the active ingredient, which resulted in a halt of sales of medroxyprogesterone after the third quarter of 2023. Subsequently, we qualified our subsidiary, ANP, to manufacture this API, and in September 2024, we re-launched the product. This decrease was partially offset by higher unit volumes of dextrose and sodium bicarbonate due to an increase in demand caused by other supplier shortages, as well as the launch of albuterol in August 2024.
Current wording
BAQSIMI® sales increased primarily due to an increase in unit volume, as we assumed full distribution responsibilities globally at the beginning of 2025. Total BAQSIMI®sales growth, including units sold by Lilly in 2024 which were accounted for in other revenues, was 12%. Primatene MIST® sales increased primarily due to an increase in unit volumes driven by our continued marketing efforts. The decrease in sales of epinephrine was due to a decrease in unit volume, impacting sales by $13.4 million, as well as a lower average selling price, which impacted sales by $10.0 million, primarily as a result of increased competition for our multi-dose epinephrine vial product. The decrease in sales of glucagon was due to a lower average selling price, which impacted sales by $24.3 million, as well as a decrease in unit volumes, impacting sales by $14.9 million, as a result of competition and the continued shift to ready to use glucagon products such as BAQSIMI®. The increase in other products was primarily due to an increase in albuterol sales of $14.7 million and iron sucrose sales of $4.4 million, which were launched in August 2024 and August 2025, respectively, as well as an increase in sales for several other products including sodium bicarbonate and atropine due to an increase in demand caused by other supplier shortages. This increase was partially offset by a decrease in sales of enoxaparin of $9.9 million and dextrose of $9.6 million due to increased competition.
Previous wording
We anticipate that sales of naloxone and enoxaparin will continue to fluctuate in the future due to competitive dynamics. We also anticipate that sales of epinephrine and other products will continue to fluctuate depending on the ability of our competitors to supply market demands.
Current wording
We anticipate that sales of glucagon will continue to decline in the future due to competitive dynamics. We also anticipate that sales of epinephrine and other products will continue to fluctuate depending on the ability of our competitors to supply market demands.

Other revenues include the portion of BAQSIMI®sales made by Lilly on our behalf under the TSA which amounted to $19.2 million and $51.2 million during the years ended December 31, 2024 and 2023, respectively, based on total BAQSIMI®sales of $37.6 million and $86.3 million, respectively, as reported to us by Lilly, which was recognized on a net basis, similar to a royalty arrangement. The BAQSIMI®sales made by Lilly on our behalf under the TSA have decreased throughout 2024, due to our assumption of distribution responsibilities for BAQSIMI®from Lilly to our customers in the United States, and certain other countries. We recognized these sales within product net revenues.
Current wording
As we completed the assumption of distribution responsibilities globally for BAQSIMI® at the beginning of 2025, all BAQSIMI® related revenues in the current period are recognized in product revenues, net.

If actual future payments for the discounts, returns, fees, rebates and chargebacks exceed the estimates we made at the time of sale, our financial position, results of operations and cash flows would be negatively impacted. We are generally obligated to accept from our customers the return of pharmaceuticals that have reached or will soon reach their expiration dates. We establish reserves for such amounts based on historical experience and other information available at the time of sale, but the actual returns will not occur until several years after the sale. Although we believe that our estimates and assumptions are reasonable as of the date when made, actual results may differ significantly from these estimates. Our financial position, results of operations and cash flows may be materially and negatively impacted if actual returns exceed our estimated allowances for returns.
