GM Chief Growth Officer Norm de Greve to Leave
General Motors announced that Norm de Greve, hired as CMO in 2023 from CVS Health and later moved into the chief growth officer role, will leave the company in June 2026 to “pursue a new endeavor,” according to his LinkedIn post. De Greve credited his team with executing what he called the largest and fastest marketing transformation in GM’s history and cited improved brand consideration and record sales for some nameplates. The departure follows an internal marketing leadership change in October 2025 when Lin-Hua Wu was promoted to CMO while retaining chief communications officer duties, shifting de Greve to chief growth officer. A GM spokesperson thanked de Greve for his contributions. The article notes the broader context of GM’s recent strategic shifts around electrification and a costly EV-related write-down earlier in 2026.
Leadership change at a major advertiser/automaker may affect the company’s marketing strategy and agency/media relationships but is not broadly industry-shifting for AdTech.
