Management, verbatim
We delivered an outstanding third quarter. Year over year, core sales grew 19% to $5.08 billion, and core EPS grew 36% to $0.91. We expanded core gross margin 150 basis points to 40.5%, core operating margin 310 basis points to 22.7%, and core ROIC 330 basis points to 16.7% – with strong adjusted free cash flow of $661 million, while investing more than half a billion in capital expenditures to address demand for our innovations. Our strong results provide excellent proof points of the acceleration of growth outlined in our ‘20-30-40’ Springboard Plan.”
Wendell P. Weeks, chairman, chief executive officer, and president
We continue to successfully expand our content within customers’ ecosystems and outperform our underlying markets. For example, in Optical Communications, faster adoption of our innovations helped us double our Gen AI sales year over year in the quarter, outpacing GPU unit growth.”
Wendell P. Weeks, chairman, chief executive officer, and president
Looking ahead, we expect our outstanding performance to continue. In the fourth quarter, we expect to grow core sales approximately 19% year over year to a range of $5.2 billion to $5.3 billion and grow core EPS approximately 36% year over year to a range of $0.96 to $1.00.”
