Values are as tagged by the issuer in XBRL. Revenue for banks and insurers is net of interest expense where that is the reported line. Fiscal years that do not follow the calendar are shown by their period-end date. No price, market cap, or valuation multiple is shown because Yield Theory does not republish unlicensed market data.

Diluted EPS is the earnings figure behind the price-to-earnings ratio; the P/E multiple compression calculator shows how a change in that multiple moves a share price. Shares outstanding multiplied by the share price gives market capitalization.

Key questions for the TDY thesis

Each question starts with what the filings show, then why it matters. None of these is a rating or a forecast.

Does TDY's reported profit turn into cash?

Operating cash flow was $1.2B, 1.33 times net income of $895M, for the fiscal year ended December 28, 2025.

Cash from operations exceeded reported earnings. Non-cash charges such as depreciation, amortization and stock-based compensation usually explain the gap; the cash-flow statement shows which.

How much of TDY's revenue is left as profit?

Net income was 14.6% of revenue for the fiscal year ended December 28, 2025, based on revenue and net income reported for the same period.

Net margin reflects the business model as much as execution, so compare it with companies in the same SEC industry and read the income statement for one-time items before treating it as a run rate.

Form 10-K filed February 20, 2026

When does Teledyne Technologies Incorporated's fiscal year end?

The SEC lists Teledyne Technologies Incorporated's fiscal year end as January 3, not December 31. The latest annual figures here run from December 30, 2024 to December 28, 2025. Its reporting year ends on a nearby date rather than a fixed calendar day.

Annual results cover a different 12 months from calendar-year peers. Align periods before comparing growth or margins across companies.
