F5 stock tumbles as hardware replacement growth slows
F5 Inc (FFIV) reported Q4 revenue growth of 13% to $917M, with product revenue up 23%. However, shares fell 18% due to weaker FY27 guidance, with expected revenue growth of 8-9% and EPS of $18-$18.30, as hardware replacement bookings are set to decline. Systems and software revenue rose 29% and 19%, respectively, while net income slightly decreased. The company authorized an additional $1.5B for share repurchases.
