Live shares outstanding are not on the quote used for price, so this page does not invent a current share count. Shares outstanding vs. float.
The latest annual report (FY 2025) used a weighted-average 109,051,215 shares. That figure is an average for the year, not the live count in the market-cap formula.
Multiplying the latest price by those FY 2025 weighted-average shares would give about $1.28B. The ranking uses the provider's reported market cap instead, which reflects a current share count rather than that annual average.
