Deutsche Bank's "Contract Research Organizations: Thoughts and Industry Feedback on AI" (March 2026)
Deloitte "Pharma's R&D lab of the future: Building a long-lasting innovation engine" (July 2025)
Biopharma demand environment stabilized and currently seeing pockets of improvement for both global biopharmaceutical and small and mid-sized biotechnology clients
Global Biopharma: Revenue to our global biopharmaceutical clients increased in 1Q26
Many of these clients have progressed through their restructuring and pipeline reprioritization activities and demand
trends have improved
Overall spending levels aren't yet back to historical levels
Small and Mid-Sized Biotech: Revenue from small and mid-sized biotech clients declined in 1Q26, primarily reflecting softer DSA booking activity last summer and normal lag between booking and revenue generation
Demand trends from biotech clients improved over past two quarters, as a result of reinvigorated funding environment
exiting 2025 and continued health in 2026
Recent increase in biopharma M&A activity has also provided another source of capital infusion or an exit strategy for biotechs
Expect small and mid-sized biotech revenue to improve in the coming quarters given our recent biotech demand KPIs (e.g. net bookings)
Mid-sized biotechs have better access to capital as they approach IND or enter the clinic
Startup biotech demand remains tepid because earlier-stage and seed funding environment remains constrained despite a recent uptick in IPO activity
Academic/Government: Revenue from global academic and government clients remained stable in 1Q26 despite government funding pressure, reflecting essential nature of our research solutions

Highlights from the quarter:
Delivered 1Q26 results despite the anticipated pressure from several discrete margin headwinds
1Q26 margin headwinds: Lower NHP revenue in RMS due to timing of shipments; higher stock compensation expense
related to CEO transition; higher NHP sourcing costs and study starts in DSA
Projecting meaningful non-GAAP operating margin improvement in 2Q26 and beyond
DSA demand environment remained solid and continues to support a return to DSA organic revenue growth in 2H26
Demonstrated by DSA net book-to-bill of 1.04x in 1Q26
Expect to generate significant operating margin expansion of ~120-150 bps in 2026 due to execution of strategic initiatives around acquisitions, divestitures, and efforts to modernize our operations
Repurchased 1.1M shares for $200M in 1Q26 under Board's $1B stock repurchase authorization

Small models: Lower revenue for small models primarily driven by lower sales volume in North America,
partially offset by solid demand for small models in China from mid-tier biotech and CRO clients
Large models (NHPs): Lower revenue was primarily affected by timing of NHP shipments, with NHP unit volume in 1Q26 expected to be the lowest point for the year
Non-GAAP operating margin: Decline was driven by unfavorable revenue mix primarily related to the timing of NHP shipments and lower sales volume for small models in North America

Revenue: Decline (organic) primarily driven by lower revenue for discovery services
Discovery: Decline due in part to prior site consolidation activities
Safety Assessment (SA): Revenue essentially unchanged in 1Q26 YOY
Non-GAAP operating margin: Decline primarily due to increased study-related direct costs (higher NHP sourcing costs and study starts)
DSA demand environment tracking to our expectations; Net bookings remained above the $600M level
driven by continued strength from our small and mid-sized biotech client base
Biotech net book-to-bill and net bookings over last 2 quarters were at the highest levels in >2 years
Demand trends for global biopharmaceutical clients remained solid in 1Q26, but declined moderately YOY after pharma bookings rebounded meaningfully to start 2025 following period of budget cuts
10 See ir.criver.com for reconciliations of GAAP to Non-GAAP results
DSA proposal activity posted a healthy increase in 1Q26
- Signal that positive bookings momentum may continue
Remain cautiously optimistic that net book-to-bill will average >1x for FY26 and support the upper end of DSA outlook
- As a reminder, our business isn't linear so net book-to-bill may not be >1x every quarter

Microbial Solutions: Strong revenue growth for Microbial Solutions, primarily driven by Endosafe® and
Celsis® manufacturing quality-control testing platforms
Biologics Testing: Biologics revenue growth rate expected to rebound as the year progresses after anniversary of a client-specific challenge that has been a headwind for past several quarters
CDMO: 1Q26 CDMO revenue growth rate negatively impacted by the loss of large commercial client in 2025
CDMO business reduced Manufacturing organic growth rate by ~350 bps in 1Q26
Comparison will no longer have a meaningful impact to organic growth going forward because of completion of the CDMO divestiture on May 6th
Non-GAAP operating margin: Improvement driven by leverage from higher revenue and the benefit from cost savings

Reaffirmed 2026 non-GAAP guidance metrics above
- Non-GAAP EPS accretion from 1Q26 stock repurchases will be essentially offset by earnings impact of FX headwind
Changes to 2026 GAAP guidance primarily reflect the impact of divestitures, as well as ~50 bps reduction to reported revenue from less favorable FX rates
Expect 2H26 non-GAAP operating margin will be >500 bps higher than expected 1H26 level
- Over half of 2H26 margin improvement expected to be driven by completed acquisitions and divestitures (incl. planned
sale of certain European Discovery Services sites in May)
(1) 2026 guidance assumes divestitures will be completed in May 2026. Non-GAAP guidance above was reaffirmed from February 25th and/or February 18th updates, respectively.

Non-GAAP EPS (Sequential)
At least 30% sequential growth vs. $2.06 in 1Q26

1Q26 headwinds from the timing of NHP shipments in the RMS segment and from NHP sourcing costs and study starts
in the DSA segment are expected to subside in 2Q26
Manufacturing non-GAAP operating margin is expected to benefit from CDMO divestiture
Expect all three segments to show sequential improvement in 2Q26 non-GAAP operating margin

(1) Charles River management believes that supplementary non-GAAP financial measures provide useful information to allow investors to gain a meaningful understanding of our core operating results and future prospects, without the effect of often-one-time charges and other items which are outside our normal operations, consistent with the manner in which management measures and forecasts the Company's performance. The supplementary non-GAAP financial measures included are not meant to be considered superior to, or a substitute for results of operations prepared in accordance with U.S. GAAP. The Company intends to continue to assess the potential value of reporting non-GAAP results consistent with applicable rules, regulations and guidance.
(2) Amortization related to acquisitions for the three months ended March 29, 2025 includes $35.5 million of accelerated amortization of certain client relationships in the Biologics Solutions reporting unit within the Manufacturing Solutions reportable segment.
(3) These adjustments are related to the evaluation and integration of acquisitions and divestitures, and primarily include transaction, advisory, certain third-party integration, certain compensation costs, and related costs; as well as fair value adjustments associated with contingent consideration arrangements.
(4) Cost savings and efficiency initiatives in 2026 primarily include site consolidation charges related to recent site optimization activities, cost of professional services related to certain improvement initiatives, and a pre-tax gain of $38.5 million in connection with the sale of certain assets in Wilmington, Massachusetts. The gain was recognized within RMS reportable segment and unallocated corporate for $23.2 million and $15.3 million, respectively.
(5) Within the DSA business, third-party legal and advisory costs incurred during fiscal 2025 relate to U.S. government investigations into the NHP supply chain, which were concluded in fiscal 2025. Also included within DSA results for fiscal 2026 is the utilization of previously written-down NHP inventory, resulting in partial reversals of the $27 million inventory charge recorded in fiscal
18 2024 following the resolution of the matter in fiscal 2025.
