Apple Names John Ternus CEO After Tim Cook's 15-Year Tenure, Sparking AI Scrutiny

Apple Inc appointed John Ternus as new CEO succeeding Tim Cook after 15 years, amid a wave of leadership changes at Best Buy and Lululemon signaling generational shifts toward digital transformation. Announced April 25, 2026, the moves raise investor questions on Apple's AI progress, supply-chain strains, and execution risks. Best Buy named Jason Bonfig (starts Nov. 1) as shares trade ~50% below 2021 peak of $138; Lululemon tapped Heidi O’Neill (starts Sept. 8), prompting sell-off to ~$143 near 2019 lows.
