Market-cap change uses historical capitalization records. Share-price returns are a different series — they can diverge when the share count changes. Those returns are not a CAGR until you pick a start value, an ending value, and years. CAGR calculator. Market cap vs. stock price.
Year-end values and the chart both come from historical market-cap records, not from applying today's share count to past prices. Latest historical observation October 2, 2026. Ranking headline cap is the snapshot figure as of October 2, 2026.

ADT Inc.'s ranking market cap is the provider-reported capitalization on the same snapshot as the rest of this site, with a share price of $6.25 as of October 2, 2026.

The ranking snapshot ($5B as of October 2, 2026) is FMP company-screener market cap. The historical observation ($4.58B on October 2, 2026) is FMP historical-market-capitalization for the same ticker. Showing the same calendar date does not make them the same observation: ranking as-of is a snapshot timestamp displayed as a date, and the historical series is a date-stamped point. The live quote market cap agrees with the ranking snapshot. This page does not replace one series with the other.
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 832,567,000 shares. That figure is an average for the year, not the live count in the market-cap formula.
