## Analysis

The firm has raised $4.8 billion across four events between 2021 and 2026, representing the total scale of the funds you are being asked to join.

## Pros and cons for an LP weighing a commitment to this manager

**Pros**

- The firm has scaled its assets under management from $3 million at founding to a current fund size of $3,900 million, indicating significant capital raising capability and institutional trust. [1] [3]
- Altimeter Capital holds a substantial position in Alphabet with 519,290 shares, reflecting a deep conviction in major technology platforms that aligns with its growth equity strategy. [2] [4]
- The manager maintains a concentrated portfolio where the top four holdings comprise almost 63% of the total, suggesting a high-conviction approach to selecting leading technology companies. [1]
- Altimeter Capital owns 13.3 million shares of Uber worth $1 billion, representing its second-largest position at 14.8% of the portfolio, demonstrating significant exposure to high-growth mobility sectors. [1]
- The firm’s crossover strategy allows it to assess private valuations against listed peers and capital-market cycles, providing an analytical edge for companies approaching institutional scale. [9]

**Cons**

- The manager exhibits extreme concentration risk, with the top four holdings comprising almost 63% of the portfolio, meaning a significant portion of LP capital is exposed to the performance of just a few companies. [1]
- A single position in Uber represents 14.8% of the portfolio (13.3 million shares worth $1 billion), creating a substantial single-name risk that could disproportionately impact overall returns if this specific asset underperforms. [1]
- The manager holds a large position in Alphabet (519,290 shares valued at $380.81 million), which, combined with the high concentration in top holdings, indicates a heavy reliance on a small number of large-cap technology stocks. [2]
- Historical data shows a significant drawdown risk in high-conviction tech bets, as evidenced by a 20% allocation to Facebook during a period when the stock experienced a 23% drawdown, highlighting the volatility inherent in the manager's concentrated strategy. [5]
