Current report

We do not believe that tariffs imposed or proposed to be imposed by the United States, particularly with the EU and China, will have a material impact on our product costs or results of operations. However, shifts in trade policies in the United States and other countries have been rapidly evolving and are difficult to predict. The ultimate impact of any announced or future tariffs will depend on various factors, including what tariffs are ultimately implemented, the timing of implementation and the amount, scope and nature of such tariffs and potential exclusions from the application of those tariffs.

Current report

On July 4, 2025, the “One Big Beautiful Bill” was signed into law, which includes significant changes to federal tax law and other regulatory provisions that may impact us. As of the date of these financial statements, we have evaluated the impact of the changes to Section 174 –Amortization of Research and Experimental Expenditureson the valuation allowance release. We intend to deduct the capitalized costs over two years. This deduction reduces the amount of net operating losses being utilized but results in a net zero change to the deferred tax asset balance. In 2025, we adjusted a portion of our valuation allowance related to our deferred tax assets in the amount of $3.8 million, which reduced our net income for the year.

Current report

Certain prior year amounts in the Consolidated Statements of Cash Flows have been reclassified to correct an error in the prior year's presentation. Specifically, for the year ended December 31, 2024, a change in deferred tax assets of $7.1 million was previously classified within "Changes in operating assets and liabilities." This amount has been reclassified to non-cash items within the operating activities section of the Consolidated Statements of Cash Flows. This reclassification had no impact on the total net cash provided by (used in) operating activities, net income, or the Consolidated Balance Sheets for any period presented.

Current report

The $0.5 million increase in current tax expense is materially consistent with the increase in net income before taxes.

Current report

On December 14, 2023, the FASB issued ASU 2023-09,Improvements to Income Tax Disclosures (“ASU 2023-09”).ASU 2023-09 amends ASC 740, Income Taxes to expand income tax disclosures and requires that the Company disclose (i) the income tax rate reconciliation using both percentages and reporting currency amounts; (ii) specific categories within the income tax rate reconciliation; (iii) additional information for reconciling items that meet a quantitative threshold; (iv) the composition of state and local income taxes by jurisdiction; and (v) the amount of income taxes paid disaggregated by jurisdiction. The Company adopted ASU 2023-09 for the year ended December 31, 2025 on a prospective basis. Accordingly, the expanded disclosures are provided for the year ended December 31, 2025, while prior period disclosures have not been retroactively adjusted and continue to be presented under the previous disclosure requirements. As this update only impacts disclosures, its adoption did not have a material impact on the Company’s consolidated financial position, results of operations, or cash flows. See Note 12Income Taxes for additional information.

Previous report

In September 2024, the Pharmacovigilance Risk Assessment Committee approved a change in existing post approval requirements for overall results and a reduction in sample size for the Pierre Fabre NERLYFE post-marketing study in Europe. As of December 31, 2024, there is a post-marketing liability of $4.6 million, and the final costs of the study are being assessed. Any adjustment to the liability will be recorded as license revenue as the original $9.0 million estimate in study costs were recorded as a reduction to license revenue.

Previous report

We have acquired, and may continue to acquire, the rights to develop new drug candidates. Payments to acquire a new drug candidate are immediately expensed as acquired in-process research and development provided that the drug candidate has not achieved regulatory approval for marketing and, absent obtaining such approval, has no alternative future use.

Previous report

In November 2023, the FASB issued Accounting Standards Update (“ASU”) 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures. The standard expands reportable segment disclosure requirements for public business entities primarily through enhanced disclosures about significant segment expenses that are regularly provided to the chief operating decision maker (“CODM”) and included within each reported measure of segment profit (referred to as the “significant expense principle”). We have adopted this standard for our fiscal year 2024 annual financial statements and interim financial statements thereafter and have applied this standard retrospectively for all prior periods presented in the financial statements. See Note 2–Significant Accounting Policies for further information.

Previous report

In October 2023, the FASB issued ASU 2023-06, Disclosure Improvements – Codification Amendments in Response to the SEC’s Disclosure Update and Simplification Initiative. The ASU modifies the disclosure or presentation requirements of a variety of Topics in the Codification to align with the SEC’s regulations. The ASU also makes those requirements applicable to entities that were not previously subject to the SEC’s requirements. The ASU is effective for us two years after the effective date to remove the related disclosure from Regulation S-X or S-K. As of the date these financial statements have been made available for issuance, the SEC has not yet removed any related disclosure. We do not expect the adoption of ASU 2023-06 to have a material effect on our consolidated financial statements.

Previous wording

We are a biopharmaceutical company that develops and commercializes innovative products to enhance cancer care and improve treatment outcomes for patients. We are currently commercializing NERLYNX, an oral version of neratinib, for the treatment of certain HER2-positive breast cancers. Additionally, in 2022, we in-licensed and became responsible for the global development and commercialization of alisertib. Alisertib is a selective, small-molecule inhibitor of Aurora Kinase A that is designed to disrupt mitosis leading to apoptosis of rapidly proliferating tumor cells that are dependent on Aurora Kinase A. Prior to our licensing alisertib from Takeda, alisertib was tested in over 1,300 patients who were treated across 22 company-sponsored trials resulting in a large, well-characterized clinical safety database. Based on information in this database, we believe alisertib has potential application in the treatment of a range of different cancer types, including hormone receptor-positive breast cancer, triple-negative breast cancer and small cell lung cancer. We intend to pursue development of alisertib initially in small cell lung cancer and hormone receptor-positive breast cancer.

Previous wording

In September 2022, we entered into an exclusive license agreement with Takeda to license the worldwide research and development and commercial rights to alisertib. Alisertib is an investigational, reversible, ATP-competitive inhibitor that is designed to be highly selective for Aurora Kinase A. Inhibition of Aurora Kinase A can lead to disruption of mitotic spindle apparatus assembly, disruption of chromosome segregation, and inhibition of cell proliferation. In clinical trials to date, alisertib has shown single agent activity and activity in combination with other cancer drugs in the treatment of many different types of cancers, including hormone receptor-positive breast cancer, triple-negative breast cancer, small cell lung cancer and head and neck cancer. We initiated the ALISertib in CAncer (ALISCA™ -Lung1) Phase II trial (PUMA-ALI-4201) of alisertib monotherapy for the treatment of patients with extensive stage small cell lung cancer in February 2024, and we commenced the ALISCA™ -Breast1 Phase II trial (PUMA-ALI-1201) in the fourth quarter of 2024.

Previous wording

Under the terms of the exclusive license agreement, we assumed sole responsibility for the global development and commercialization of alisertib. We paid Takeda an upfront license fee of $7.0 million in October 2022, and it is eligible to receive potential future milestone payments of up to $287.3 million upon our achievement of certain regulatory and commercial milestones over the course of the exclusive license agreement, as well as tiered royalty payments for any net sales of alisertib. We recorded in-process research and development expense of $7.0 million during the year ended December 31, 2022, in connection with the up-front payment related to the asset acquisition. As of December 31, 2024, no milestones had been accrued as the underlying contingencies were not probable or estimable.

Previous wording

Our expenses to date have been related to hiring staff, commencing company-sponsored clinical trials and the build out of our corporate infrastructure and, since 2017, the commercial launch of NERLYNX. Going forward, we anticipate significant expenses as we continue todevelop alisertib in 2025. Accordingly, our success depends not only on the safety and efficacy of our drug candidates, but also on our ability to finance product development. To date, our major sources of working capital have been proceeds from product and license revenue, public offerings of our common stock, proceeds from our credit facility and sales of our common stock in private placements. We intend to satisfy our near-term liquidity requirements through a combination of our existing cash and cash equivalents and marketable securities as of December 31, 2024, and proceeds that will become available to us through product sales, royalties and sub-license milestone payments. However, this intention is based on assumptions that may prove to be wrong. Changes may occur that would consume our available capital faster than anticipated, including changes in and progress of our development activities, the impact of commercialization efforts, acquisitions of additional drug candidates and changes in regulation. Some of these developments have had and may continue to have an adverse effect on our revenue and thus could have an adverse effect on our ability to satisfy the minimum revenue and cash balance covenants contained in the Athyrium Notes.

Previous wording

Total revenue was approximately $230.5 million for the year ended December 31, 2024, compared to $235.6 million for the year ended December 31, 2023. This decrease in total revenue of $5.2 million was due to a decrease in product revenue, net of approximately $7.9 million, partially offset by an increase in royalty revenue of $2.8 million.

Current wording

Total revenue was approximately $228.4 million for the year ended December 31, 2025, compared to $230.5 million for the year ended December 31, 2024. This decrease in total revenue of $2.1 million was due to a decrease in royalty revenue of $11.0 million, partially offset by an increase in product revenue, net of approximately $8.9 million.

Previous wording

Product revenue, net was approximately$195.2 million for the year ended December 31, 2024, compared to$203.1 million for the year ended December 31, 2023. The decrease in product revenue, net was primarily attributable to a volume decrease of approximately 8.7% in bottles of NERLYNX sold, partially offset by an increase in net selling price. Reserves for variable consideration were approximately 19.5% and 17.9% of product revenue for the years ended December 31, 2024 and 2023, respectively. The increase in the variable consideration (gross-to-net reserve) was due to prior year adjustments related to lower Medicaid claims.

Current wording

Product revenue, net was approximately$204.1 million for the year ended December 31, 2025, compared to$195.2 million for the year ended December 31, 2024. The increase in product revenue, net was primarily attributable to a volume increase of approximately 5.5% in bottles of NERLYNX sold and an increase in net selling price. Reserves for variable consideration were approximately 24.3% and 19.5% of product revenue for the years ended December 31, 2025 and 2024, respectively. The increase in the variable consideration (gross-to-net reserve) was primarily due to government chargebacks and payor mix.

Previous wording

Royalty revenue was approximately$35.3 million for the year ended December 31, 2024, compared to$32.5 million for the year ended December 31, 2023. The increase was due to increased product sales by our sub-licensees as they increased commercialization of NERLYNX in international territories, primarily in China.

Current wording

Royalty revenue was approximately$24.3 million for the year ended December 31, 2025, compared to$35.3 million for the year ended December 31, 2024. The decrease was due to decreased product sales by our sub-licensees in international territories, primarily in China.

Previous wording

Cost of sales was approximately$64.4 million for the year ended December 31, 2024, compared to$62.7 million for the year ended December 31, 2023. The $1.7 million increase was primarily due to the increase of product unit sales to our sub-licensees and the related cost of sales (primarily sales in China), partially offset by lower domestic sales.

Current wording

Cost of sales was approximately$58.2 million for the year ended December 31, 2025, compared to$64.4 million for the year ended December 31, 2024. The $6.2 million decrease was primarily due to the decrease of product unit sales to our sub-licensees and the related cost of sales (primarily sales in China), partially offset by higher domestic sales.

For the year ended December 31, 2024, we recognized approximately $4.7 million in interest income compared to approximately $2.6 million of interest income for the year ended December 31, 2023. The $2.1 million increase in interest income was primarily the result of increased balances in cash equivalents and marketable securities.

Current wording

For the year ended December 31, 2025, we recognized approximately $4.1 million in interest income compared to approximately $4.7 million of interest income for the year ended December 31, 2024.

Current wording

For the year ended December 31, 2025, we recognized approximately$6.6 million in interest expense compared to approximately$12.5 million of interest expense for the year ended December 31, 2024. The approximately$5.8 million decrease in interest expense was primarily related to a lower debt balance related to the pay down our debt principal during the year ended December 31, 2025.

Previous wording

For the year ended December 31, 2024, we recognized approximately $0.9 million in other income, primarily due to increased income related to the termination of our sublease and resulting settlement payment of $0.5 million, partially offset by unfavorable exchange rates in Euro-denominated transactions.

Current wording

For the year ended December 31, 2025, we recognized approximately $1.0 million in other income, compared to $0.9 million in other income for the year ended December 31, 2024. The increase was primarily due to increased sublease income.

In 2024, we released a portion of our valuation allowance related to our deferred tax assets in the amount of $7.1 million, which significantly increased our net income for the year.

Current wording

In the fourth quarter of 2025, Puma recorded a $7.1 million income tax expense, offset by a $3.8 million partial release of a valuation allowance resulting in a non-cash, deferred tax expense of approximately $3.2 million.

In addition to our operating results, as calculated in accordance with generally accepted accounting principles in the United States, (“GAAP”), we use certain non-GAAP financial measures when planning, monitoring, and evaluating our operational performance. The following table presents our net income and net income per share, as calculated in accordance with GAAP, as adjusted to remove the impact of stock-based compensation. For the year ended December 31, 2024, stock-based compensation represented approximately 6.1% of the total of SG&A and R&D expenses. Our management believes that these non-GAAP financial measures are useful to enhance understanding of our financial performance, are more indicative of our operational performance and facilitate a better comparison among fiscal periods. These non-GAAP financial measures are not, and should not be viewed as, substitutes for GAAP reporting measures.

We may choose to begin new R&D efforts, launch additional marketing efforts or pursue other in-licensing opportunities. These efforts will require funding in addition to the cash and cash equivalents totaling approximately $69.2 million and approximately $31.7 million in marketable securities available at December 31, 2024. While our consolidated financial statements have been prepared on a going concern basis, we may incur significant losses in the future and will need to generate significant revenue to sustain operations and successfully commercialize neratinib and develop alisertib. While we have been successful in raising financing in the past, there can be no assurance that we will be able to do so in the future. Our ability to obtain funding may be adversely impacted by uncertain market conditions, our success in commercializing neratinib, our success in developing alisertib, unfavorable decisions of regulatory authorities or adverse clinical trial results. The outcome of these matters cannot be predicted at this time. We believe that our existing cash and cash equivalents and marketable securities as of December 31, 2024, and proceeds that will become available to us through product sales and sub-license payments are sufficient to satisfy our operating cash and capital needs for at least one year after the filing of this Annual Report.
