Agilent (A) Stock Surges 16.1% After Earnings Beat and Upward Guidance Revision

Shares of Agilent Technologies (NYSE:A) jumped 16.1% on May 28, 2026, after the life sciences tools maker reported fiscal second-quarter results that exceeded expectations and raised its full-year profit outlook, signaling a faster-than-expected recovery in lab equipment spending. Adjusted earnings per share beat the top end of management’s own guidance by $0.07, driven by a replacement cycle for aging instruments that CEO Padraig McDonnell described as a 200-300 basis point tailwind to growth. Pharmaceutical revenue rose 6%, biotech grew at low double digits, and the company directly cited the GLP-1 weight-loss drug wave as a structural driver, with its instruments positioned in quality-control and development labs for scaled production. Agilent raised its full-year EPS guidance to $6.00-$6.10 from $5.90-$6.04, a step-up reflecting confidence in durable margin improvements as its “Ignite” operating system becomes structurally embedded rather than piloted.
