Manufacturing Market Demand

CHARLES RIVER LABORATORIES INTERNATIONAL, INC. · 2026-08-05 · Importance 24 · Surprise 32

Manufacturing demand increased across the company’s three major geographic regions, led by high-single-digit growth in Microbial Solutions. Demand was strongest for endotoxin-testing reagents, including PTS rapid-testing cartridges, and the business added new clients to its broad quality-control testing platform. Biologics Testing growth was more modest because of a client-specific challenge that had been a headwind since mid-2025, while CDMO reduced reported organic growth during the partial quarter before its divestiture. Management expects Biologics Testing growth to rebound after the prior-year headwind anniversary.

Key facts

• Manufacturing revenue increased 1.3% organically in the second quarter, with Microbial Solutions increasing at a high single-digit rate.
