Hertz Global Holdings: Bill Ackman's Bullish Thesis Boosts Shares Amid Ongoing Challenges

Hertz Global Holdings' stock has risen 6% after prominent investor Bill Ackman publicly highlighted a bullish analysis on the car rental group. Ackman's endorsement may influence near-term trading, but it doesn't change the key near-term catalyst of progress toward profitability or the central risk of financial leverage and volatile earnings. Hertz's recent Q3 2025 update showed revenue of $2,478 million and quarterly profitability, but the company still carries negative equity and relies on digital initiatives and mobility partnerships to outweigh current losses.
