Valuation, from the filing
| Public float | $10.30B | Market value of stock held by non-affiliates, as stated on the cover page for 2025-05-03 |
|---|---|---|
| Float per share | $73.12 | 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 | 83.5× | A lower bound on the multiple, because affiliate holdings are excluded. |
| Float / revenue | 2.2× | A lower bound on the multiple, because affiliate holdings are excluded. |
| Float / equity | 3.8× | 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 2025-05-03, not today, and each multiple below it uses the figures for the fiscal year ending 2025-11-01 — the year that filing covered.
Valuation over time
83.5× earnings today, against a median of 26.7× across 7 years on record. Above its own history.
| Float measured | Public float | Float / net income | |
|---|---|---|---|
| 2025-05-03 | $10.30B | 83.5× | |
| 2024-04-26 | $6.70B | 79.8× | |
| 2023-04-28 | $6.80B | 26.7× | |
| 2022-04-29 | $8.30B | 54.3× | |
| 2021-04-30 | $7.80B | 15.6× | |
| 2020-05-01 | $7.10B | 19.7× | |
| 2019-05-03 | $6.00B | 23.7× |
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.
How this compares in its industry
Percentile among the Telephone & Telegraph Apparatus filers on this site, highest value first. A high percentile means a large figure, which is good for a margin and not for leverage — the ranking says where the company sits, not whether that is where it should be.
