Yahoo COO Henrique De Castro, Mayer's No. 2, to depart after failing to move lagging ad business
“Dead Man Walking” Walks: COO Henrique De Castro Out at Yahoo — As has long been rumored, Yahoo COO Henrique De Castro is departing Yahoo. I had reported last week that he was in big trouble …
Context & Ripple Effects
Henrique De Castro arrived at Yahoo in October 2012 as Marissa Mayer's marquee hire, lured from Google with what AllThingsD called a $56 million compensation package to fix the company's core problem: display advertising. By September 2013, Adweek was reporting he had to deliver results or face ouster by year's end — and this firing closes that loop.
The departure lands amid a rough stretch for Yahoo's ad machine: days earlier the company went silent on how its ad servers served malware to European homepage visitors, even as it kept buying product assets like the Aviate homescreen startup. The story travelled unusually wide for an exec exit — WSJ, Forbes, CNET and six other outlets all picked it up same-day — reflecting how much of Mayer's turnaround thesis rested on her No. 2.
First-order effects
- Yahoo's advertising organization loses its top executive overnight, leaving Mayer without a designated No. 2 just as she takes personal ownership of the ad revenue problem De Castro failed to move.
Second-order effects
- Rivals and ad buyers now price Yahoo's display business as leaderless, pressuring Mayer to either promote internally or make another high-profile external hire — repeating the costly bet she made with De Castro.
Third-order effects
- If the pattern holds, Yahoo's turnaround becomes a case study in the limits of importing big-company talent at premium packages: the $56 million hire produced no ad recovery, raising the bar for any successor to justify similar spending.
The trend: Turnaround-era Yahoo is cycling through expensive Google-imported executives as its ad business fails to recover, testing whether CEO-level intervention can replace dedicated ad leadership.
