Valuation, from the filing
| Public float | $900.00M | Market value of stock held by non-affiliates, as stated on the cover page for 2025-06-30 |
|---|---|---|
| Float per share | $37.85 | Float divided by shares outstanding in the same filing. A floor under the share price on that date, not the price itself. |
| Float / net income | 42.4× | A lower bound on the multiple, because affiliate holdings are excluded. |
| Float / revenue | 1.7× | A lower bound on the multiple, because affiliate holdings are excluded. |
| Float / equity | 1.3× | A lower bound on the multiple, because affiliate holdings are excluded. |
Every figure here is drawn from the 10-K cover page and the statements behind it, so each one traces to a filing. Public float counts only stock held by non-affiliates, which makes these floors rather than estimates: a high multiple is conclusive, a low one may mean cheap or may mean closely held. The float was measured on 2025-06-30, not today, and each multiple below it uses the figures for the fiscal year ending 2025-12-31 — the year that filing covered.
Valuation over time
42.4× earnings today, against a median of 48.2× across 9 years on record. Below its own history.

| 2020-06-30 | $3.00B | 59.0× | |
| 2019-06-30 | $3.10B | 48.7× | |
| 2018-06-30 | $3.20B | 41.8× | |
| 2017-06-30 | $1.80B | 34.8× | |
| 2016-06-30 | $1.40B | 32.8× |
Each float is paired with the fiscal year the filing that stated it covers. Only years where the company reported positive net income appear, because a multiple against a loss is not a multiple.
