Teledyne Technologies Incorporated (TDY)
Aeroespacial, defensa e instrumentación industrial
A diversified portfolio of niche technology businesses—digital imaging, instrumentation, defense electronics—with stable technical moat, ROIC below the 10% bar (goodwill drag from two decades of acquisitions) and shares that, after rising ~43% from their 52-week low on record results and elevated guidance, trade at 25× — No margin of safety: at this price capital is preserved, but it is not bought below its value..

The essentials
- Four segments—Digital Imaging (52% of sales), Instrumentation (24%), Aerospace and Defense Electronics (17%, fastest growing), Engineered Systems (7%)—with no competitor offering the same product-line combination or serving the same end markets, per the 10-K itself.
- Historical growth is irregular and heavily M&A-dependent: FY2025's +7.9% included ~US$270M of incremental M&A revenue (more than half the total increase), while 2Q26 showed mostly organic acceleration (+9.8% with only US$12.2M in M&A gains).
- ROIC ~8.0% on real capital invested (equity + debt − cash), below the 10% bar — structural goodwill drag from two decades of acquisitions (US$8,688M goodwill on US$15,280M total assets), not necessarily indicative of poor operations (BSX/DHR rule).
- The company raised its 2026 GAAP EPS guidance to US$20.73-20.99 (from US$20.08-20.44) following a record second quarter in orders, sales, and operating profit, with funded backlog of ~US$5.0bn and consolidated leverage of 1.1× after repaying US$450M of debt.
- No dividend; returns capital via share buyback (~US$403M in FY2025, ~1.7% of shares) and reinvests the excess in add-on acquisitions.
Intrinsic value — two valuation methods
The methods disagree: one places the value today above the price ($626) and the other below.
Pillars of the analysis
The verdict — today vs 5 years
Today — expensive, no margin of safety: at $626 trades ~14.0% above its value discounted to today (~$549); the expected return does not even reach the risk-free rate (4.5%).
At 5 years — Preserva valor: the target price ($684) plus dividends yield just enough to preserve nominal capital, below the required 4% floor.
The bridge: the return at 5 years falls below the risk-free rate (4.5%) — which is why there is not even a discount to today's value. To require a 15% annual return, it would need to be bought at ~$340.
Thesis
The business
A portfolio of niche technical businesses with stable technical moat—specialized expertise, supplier switching costs, diversified customer base—but not an exceptional-quality compounder: ROIC (~8.0%) falls below the 10% bar, partly due to goodwill accumulated over two decades of acquisitions (BSX/DHR pattern, not necessarily poor operations).
The valuation
Valuation by multiples (EV/EBIT, aerospace archetype, band 15-22×): the 5-year value emerges from projecting each year's EBIT with a growth trajectory decelerating from +8.0% to +5.5% and a terminal exit multiple of 25×, within the band but in its lower-mid range given the below-bar ROIC. Result: $684 per share, versus a market price of US$691.73 that already pays 25× the trailing-twelve-month EV/EBIT.
Margin of safety
No margin of safety: at this price capital is preserved, but it is not bought below its value. The base CAGR at market price is +2%, placing Teledyne at Preserves value: the stock rose ~43% from its 52-week low on record results and elevated guidance, and current pricing already captures much of that strength.
What to watch
The central disconfirmer is whether recent growth proves sustainable without unannounced acquisitions: if organic acceleration from 2Q26 fades to the weaker FY23-FY24 pattern (+3.2% / +0.6%), the rich entry multiple has nothing to support it. Also monitor dependence on U.S. defense spending (25.5% of sales, subject to Congressional appropriations) and goodwill impairment risk given its balance sheet weight (US$8,688M).
