John Ternus Takes Over as Apple CEO From Tim Cook

John Ternus officially became the chief executive officer of Apple on September 1, 2026, succeeding Tim Cook, who concluded a 15-year tenure leading the technology giant. The transition, announced earlier in the year and unanimously approved by the board, marks the end of a carefully planned succession. Cook, who joined Apple in 1998 and took over as CEO in 2011 following the resignation of co-founder Steve Jobs, will remain with the company as executive chairman. In a final memo to employees sent on his last day as CEO, Cook expressed deep gratitude and reflected on his time at the helm.
