Summary
Summary of the 10-Q filed August 6, 2025. Cited figures are marked; the original filing is the authoritative source.
Amgen Inc. reported robust top-line growth for the second quarter and first half of 2025, with total revenues increasing by 9%a and 10% respectively compared to the prior year periods.
This growth was primarily driven by strong volume increases across key products, notably Repatha, EVENITY, BLINCYTO, and TEZSPIRE, which collectively offset modest net selling price declines. The company demonstrated significant profitability improvements, with net income soaring by 92%b and 92% for the respective periods, and diluted EPS more than doubling year-over-year. This performance was supported by improved cost of sales as a percentage of revenue and well-managed selling, general, and administrative expenses, although R&D investments saw an increase.
Despite the strong operational performance, investors should note the ongoing legal challenges, particularly the significant tax dispute with the IRS concerning past tax years, which continues through the judicial process. The company also faces ongoing patent litigations related to its key products like Repatha and Prolia/XGEVA, with several new biosimilar infringement lawsuits filed.
While Amgen has a strong liquidity position with substantial cash and cash equivalents, its balance sheet reflects a notable decrease in cash from the prior year-end, largely due to significant debt repayments and dividend distributions. The company reiterated its commitment to capital allocation through debt reduction, dividends, and stock repurchases.

05—Questions
Frequently Asked Questions
What drove the significant increase in Amgen's net income and EPS?
The substantial increase in net income and EPS for both the three and six months ended June 30, 2025, was primarily driven by a strong increase in total revenues due to volume growth in key products, coupled with a more favorable cost of sales as a percentage of revenue. These factors collectively led to a significant increase in operating income, which flowed down to net income and EPS. Improved management of selling, general, and administrative expenses also contributed to the profitability gains.
What is the status of Amgen's tax dispute with the IRS?
Amgen is contesting IRS notices for tax years 2010-2012 and 2013-2015, which propose significant adjustments related to profit allocation between U.S. and Puerto Rico entities, potentially resulting in substantial additional federal tax liabilities. The trial for the consolidated cases concluded in January 2025, with post-trial briefs due in October 2025. A decision from the U.S. Tax Court is not expected earlier than the second half of 2026. The company also faces ongoing examinations for later tax years and believes its accrual for income tax liabilities is appropriate, but acknowledges the uncertainty and potential for material adverse impact.
How is biosimilar competition impacting Amgen's key products?
Amgen is experiencing or anticipating biosimilar competition for several of its products. For Prolia and XGEVA, patents expired in early 2025 in the U.S., and biosimilar competition has launched, leading to expected sales erosion in the second half of 2025. The company is actively engaged in litigation to defend its patents against biosimilar developers for these and other products.
What are the key R&D developments highlighted in this report?
Amgen highlighted interim results from the Phase 3 DeLLphi-304 trial for IMDELLTRA/IMDYLLTRA in small cell lung cancer, showing a significant reduction in the risk of death. Additionally, the Phase 3 FORTITUDE-101 trial for bemarituzumab in gastric cancer met its primary endpoint of overall survival. The company also presented data for MariTide™ (maridebart cafraglutide) in obesity, showing substantial weight loss and cardiometabolic improvements. Marketing authorization for TEPEZZA was granted in Europe for thyroid eye disease.
