Non-GAAP EPS excludes acquisition- and divestiture-related costs and costs related to restructuring programs, as well as income and losses from investments in equity securities.

GAAP Expense, EPS and Related Information
Gross margin was 73.5% for the second quarter of 2026 compared with 77.5% for the second quarter of 2025. The decrease was primarily due to higher amortization of intangible assets and inventory write-downs.
Selling, general and administrative (SG&A) expenses were $2.9 billion in the second quarter of 2026, an increase of 10% compared with the second quarter of 2025. The increase was primarily due to higher administrative costs (including investments in IT), as well as higher promotional costs in support of product launches.
Research and development (R&D) expenses were $9.7 billion in the second quarter of 2026 compared with $4.0 billion in the second quarter of 2025. The increase was largely due to a $5.7 billion charge for the acquisition of Terns and higher clinical development spending, partially offset by a $200 million reduction in R&D expenses as part of a funding agreement with Blackstone Life Sciences (Blackstone). R&D expenses in the second quarter of 2025 include a $200 million charge for an upfront payment related to a license agreement with Hengrui Pharma.
Other (income) expense, net, was $99 million of expense in the second quarter of 2026 compared with $7 million of income in the second quarter of 2025. The unfavorability was primarily due to higher net interest expense, partially offset by higher net income from investments in equity securities.
The income tax provision for the second quarter of 2026 was $654 million on a pretax loss of $683 million, resulting in an effective income tax rate of (95.9)%. This effective income tax rate includes a 108.9 percentage point unfavorable impact of the charge for the acquisition of Terns, for which no tax benefit was recorded.
GAAP loss per share was $0.54 for the second quarter of 2026 compared with earnings per share of $1.76 for the second quarter of 2025, largely due to higher charges for business development transactions, reflecting a $2.31 per share charge in the second quarter of 2026 for the acquisition of Terns compared with a $0.07 per share charge in the second quarter of 2025 related to a license agreement with Hengrui Pharma.
Non-GAAP Expense, EPS and Related Information
Non-GAAP gross margin was 81.1% for the second quarter of 2026 compared with 82.2% for the second quarter of 2025. The decrease was primarily due to higher inventory write-downs.
Non-GAAP SG&A expenses were $2.9 billion in the second quarter of 2026, an increase of 10% compared with the second quarter of 2025. The increase was primarily due to higher administrative costs (including investments in IT), as well as higher promotional costs in support of product launches.
Non-GAAP R&D expenses were $9.7 billion in the second quarter of 2026 compared with $4.0 billion in the second quarter of 2025. The increase was largely due to a $5.7 billion charge for the acquisition of Terns and higher clinical development spending, partially offset by a $200 million reduction in R&D expenses as part of a funding agreement with Blackstone. R&D expenses in the second quarter of 2025 include a $200 million charge for an upfront payment related to a license agreement with Hengrui Pharma.
Non-GAAP other (income) expense, net, was $290 million of expense in the second quarter of 2026 compared with $54 million of expense in the second quarter of 2025. The unfavorability was primarily due to higher net interest expense.
The non-GAAP income tax provision for the second quarter of 2026 was $882 million on pretax income of $550 million, resulting in a non-GAAP effective income tax rate of 160.3%. This effective income tax rate includes a 146.2 percentage point unfavorable impact of the charge for the acquisition of Terns, for which no tax benefit was recorded.
Non-GAAP loss per share was $0.13 for the second quarter of 2026 compared with earnings per share of $2.13 for the second quarter of 2025, largely due to higher charges for business development transactions, reflecting a $2.31 per share charge in the second quarter of 2026 for the acquisition of Terns compared with a $0.07 per share charge in the second quarter of 2025 related to a license agreement with Hengrui Pharma.
