Charles River's first full quarter under new CEO Birgit Girshick delivered Q1 results in line with lowered expectations, with $996M in revenue declining 1.5% organically and non-GAAP EPS falling 12% to $2.06 on anticipated discrete headwinds including CEO transition stock comp and NHP sourcing costs. The DSA demand environment remained constructive with a 1.04x net book-to-bill on $622M in bookings and proposal activity up in the high single digits, though biotech revenue still lagged on the booking-to-revenue time lag. Management reaffirmed FY2026 EPS guidance of $10.80-$11.30 and expects over 500 basis points of operating margin improvement between the first and second halves of the year, driven by KF Cambodia sourcing savings, completed CDMO/Cell Solutions divestiture, and incremental efficiency initiatives.
