Key Decisions & Impact
Became CEO on January 1, 2026 after leading Kellogg Company and Kellanova from 2017 through Mars's acquisition of Kellanova. In February 2026 he paused the planned separation and committed about $600 million of incremental investment in marketing, R&D, sales, and pricing, raised to about $700 million in August 2026.
Legacy
Shifted the company's priority from structural change to rebuilding volume in its core brands; first-half 2026 sales declines narrowed and 2026 guidance was raised.
