Stronger bookings in Discovery & Safety Assessment and demand from biotech clients drove an earnings beat and higher guidance. Operational efficiencies, portfolio optimization and manufacturing automation are supporting margin improvement. Buybacks and a strong balance sheet add support to sustained earnings expansion as funding markets stabilize.
