The impact of foreign currency translation increased reported revenue by 1.9%, and the divestiture of a small Safety Assessment site in 2024 reduced reported revenue by 0.1%. Excluding the effect of these items, revenue declined 2.6% on an organic basis, driven primarily by the Discovery and Safety Assessment (DSA) and Manufacturing Solutions (Manufacturing) segments.

In the fourth quarter of 2025, the GAAP operating margin was (28.5)%, compared to (16.7)% in the fourth quarter of 2024. The GAAP net loss available to common shareholders for the fourth quarter of 2025 was $(276.6) million, or $(5.62) per diluted share, compared to a net loss of $(215.7) million, or $(4.22) per diluted share for the same period in 2024. GAAP net income and earnings per share included non-cash intangible asset impairments of $211.0 million, or $3.22 per share, for the Biologics Solutions reporting unit (Manufacturing segment) and the Cell Solutions business (RMS segment) and a non-cash goodwill impairment totaling $165.0 million, or $3.35 per share, in the Biologics Solutions reporting unit in the fourth quarter of 2025, compared to a non-cash goodwill impairment of $215.0 million, or $4.20 per share, in the Biologics Solutions reporting unit in the fourth quarter of 2024. In the fourth quarter of 2025, the Company reported a gain of $0.10 per share on certain venture capital and other strategic investments, compared to a loss of $0.32 per share in the fourth quarter of 2024.

On a non-GAAP basis, the fourth-quarter operating margin decreased to 18.1% from 19.9% in the fourth quarter of 2024, primarily as a result of lower revenue, higher study-related direct costs in the DSA segment, and an unfavorable revenue mix in the RMS segment. Non-GAAP net income was $118.8 million for the fourth quarter of 2025, a decrease of 13.0% from $136.6 million for the same period in 2024. Fourth-quarter diluted earnings per share on a non-GAAP basis were $2.39, a decrease of 10.2% from $2.66 per share for the fourth quarter of 2024. The non-GAAP net income and earnings per share decreases were driven primarily by lower revenue and operating margin, as well as a higher tax rate.

James C. Foster, Chair, President and Chief Executive Officer, said, "We were pleased with our 2025 financial results, including substantial improvement in DSA net bookings in the fourth quarter that demonstrates the stabilization of the biopharmaceutical demand environment. We are making significant progress on several strategic initiatives that will enable the Company to better capitalize on future growth opportunities, and we remain intently focused on scientific innovation that will reinforce our position as the leader in preclinical drug development."
"As we look ahead, we are cautiously optimistic that positive demand trends will continue in 2026. We remain committed to driving our strategy forward, including through selective and strategic acquisitions that align with our core competencies; taking decisive actions to drive efficiency and process improvements that will deliver continued benefits; and by strengthening and refining our organization to enhance our speed and responsiveness. This approach ensures Charles River remains the partner of choice for our clients as the biopharmaceutical demand environment continues to improve," Mr. Foster concluded.

Fourth-Quarter Segment Results

Research Models and Services (RMS)
Revenue for the RMS segment was $206.3 million in the fourth quarter of 2025, an increase of 1.0% from $204.3 million in the fourth quarter of 2024. The impact of foreign currency translation increased revenue by 1.9%. Organic revenue decreased by 0.9%, due primarily to lower revenue for large research models and for small research models in North America. The decline was partially offset by higher revenue for research model services, including in the Insourcing Solutions business, and small research models in China and Europe.
In the fourth quarter of 2025, the RMS segment’s GAAP operating margin decreased to (33.6)% from 6.7% in the fourth quarter of 2024 primarily due to the intangible asset impairment related to the Cell Solutions business. On a non-GAAP basis, the operating margin decreased to 21.9% from 22.8%. The non-GAAP operating margin decrease was primarily driven by the unfavorable revenue mix related to large research models and lower revenue for small research models in North America.

Discovery and Safety Assessment (DSA)

Revenue for the DSA segment was $591.6 million in the fourth quarter of 2025, a decrease of 2.0% from $603.3 million in the fourth quarter of 2024. The impact of foreign currency translation increased DSA revenue by 1.5% and the divestiture of a small DSA site reduced reported revenue by 0.2%. Organic revenue decreased by 3.3%, driven primarily by lower sales volume for discovery services, and also for regulated safety assessment services.
In the fourth quarter of 2025, the DSA segment’s GAAP operating margin increased to 14.3% from 10.4% in the fourth quarter of 2024. The increase was primarily driven by a favorable comparison to the prior year’s large model (NHP) inventory write down. On a non-GAAP basis, the operating margin decreased to 20.1% from 24.7% in the fourth quarter of 2024. The non-GAAP operating margin decrease was primarily driven by lower revenue, as well as higher study-related direct costs related to large-model sourcing and staffing.
Manufacturing Solutions (Manufacturing)
Revenue for the Manufacturing segment was $196.4 million in the fourth quarter of 2025, an increase of 0.7% from $194.9 million in the fourth quarter of 2024. The impact of foreign currency translation increased Manufacturing revenue by 2.8%. Organic revenue decreased 2.1%, driven by lower revenue in the CDMO business, partially offset by higher revenue in the Microbial Solutions and Biologics Testing businesses.
The Manufacturing segment’s GAAP operating margin was (115.9)%, compared to (93.6)% in the fourth quarter of 2024. The decrease was primarily the result of larger impairments in the fourth quarter of 2025 related to the Biologics Solutions reporting unit, which includes both the CDMO and Biologics Testing businesses. On a non-GAAP basis, the operating margin increased to 32.1% from 28.7% in the fourth quarter of 2024, driven primarily by the benefit of cost savings resulting from the Company’s restructuring initiatives.

On a non-GAAP basis, net income was $512.3 million in 2025, a decrease of 3.9% from $532.9 million in 2024. Diluted earnings per share on a non-GAAP basis in 2025 were $10.28, a decrease of 0.4% from $10.32 in 2024.
Research Models and Services (RMS)
For 2025, RMS revenue was $846.1 million, an increase of 2.0% from $829.4 million in 2024. Revenue increased by 1.2% on an organic basis.

On a GAAP basis, the RMS segment operating margin decreased to 5.3% in 2025 from 13.8% in 2024. On a non-GAAP basis, the operating margin increased to 24.8% in 2025 from 23.7% in 2024.
Discovery and Safety Assessment (DSA)

On a GAAP basis, the DSA segment operating margin decreased to 17.7% in 2025 from 18.1% in 2024. On a non-GAAP basis, the operating margin decreased to 24.2% in 2025 from 25.7% in 2024.
Manufacturing Solutions (Manufacturing)

2026 Guidance
The Company is providing financial guidance for 2026, which does not include the impact of planned divestitures that represent approximately 7% of annual revenue for 2025 and estimated 2026. On an organic basis, this outlook assumes that the robust DSA booking trends in the fourth quarter of 2025, combined with an expectation that favorable booking activity will continue in 2026, will result in a return to organic revenue growth in the second half of 2026 on both a consolidated basis and for the DSA segment. In addition, the Company also expects revenue will increase organically in the Manufacturing segment, as a result of the anniversary of the loss of a large, commercial CDMO client in 2025 and a continuation of solid demand trends in the Microbial Solutions business. The revenue increase is expected to be partially offset by lower revenue in the RMS segment due to lower large model revenue, as well as lower revenue in its Insourcing Solutions business, principally related to its CRADLTM operations.
Non-GAAP earnings per share are expected to increase by approximately 4% to 9% in 2026, as a result of the benefit from incremental cost savings related to restructuring and efficiency initiatives, as well as the earnings accretion from the completed acquisition of the assets of K.F. (Cambodia) Ltd. A lower tax rate will also contribute to non-GAAP earnings per share growth in 2026.
The Company’s 2026 guidance for revenue and earnings per share is as follows:

Revenue growth/(decrease), reported
At Least Flat to +1.5%
