The Meta Story — Gerstner's Defining Moment

In October 2022, Brad Gerstner published an open letter to Mark Zuckerberg that became one of the most talked-about investor communications in recent memory:

• Called on Meta to reduce headcount by at least 20%
• Urged the company to cap metaverse/Reality Labs spending at $5B/year
• Recommended a $50B stock buyback program
• Within weeks, Meta announced massive layoffs and spending cuts
• Meta's stock subsequently rallied over 300% from its lows

While Gerstner wasn't the only voice calling for change, his public letter crystallized market sentiment and demonstrated his willingness to push for value creation at portfolio companies.

Altimeter Growth Corp — The SPAC Chapter

Altimeter entered the SPAC boom with Altimeter Growth Corp (AGC), which merged with Grab Holdings:

• Deal size: $40 billion enterprise value at announcement — largest SPAC deal in history at the time
• Outcome: Grab's stock declined significantly post-merger, reflecting the broader SPAC market correction
• Lesson: the deal illustrated both the potential and risks of the SPAC vehicle

• 2021: strong returns as tech growth stocks surged
• 2022: significant drawdown as growth/tech stocks corrected sharply
• 2023-2024: strong recovery, driven by Meta's turnaround and AI-driven tech rally
