Shares of Amphenol popped 6.3% to $159.88 on July 30, the latest move in a 12‑month run that has the stock up 51.8% and the two‑year gain at 158.9%.
The numbers driving that rally are hard to miss: revenue landed at $23.1B, a 51.7% year‑over‑year jump, while operating margin expanded to 25.4% and net margin to 18.5%. Operating cash flow covered net income at 1.26x in the latest year.
In the rear‑view: the company reported $15.2B in revenue in 2024, then $23.1B in 2025. That leap shows up in the trend lines and in the headline growth rates investors read every quarter.
The counterpoint is valuation. Amphenol trades at a P/E of 47.8x and EV/sales of 8.4x, with an earnings yield of 2.1% and a cash‑flow yield of 2.6%. Its multiples sit meaningfully above peer medians: P/E is +26.6% higher, EV/sales is +49.4% above the peer set.
The company’s own scenario math, presented mechanically from recent history, not as a forecast, illustrates why those multiples matter. The bull and base scenarios use a two‑year revenue CAGR of +22.3% with an exit P/E of 47.8x; the bear case assumes a +8.9% CAGR and a lower exit P/E of 33.5x. The gap between outcomes is driven mostly by what multiple gets applied at the exit, not changes in near‑term sales growth.
The profit improvement is real on paper: operating margin widened by 4.7 percentage points in the latest year and net margin rose by 2.6 points. Diluted shares increased 1.1%. At the same time the company sits at scale: market cap $204.2B, enterprise value $193.1B.
That frames a tension between faster revenue and higher operating profits and cash flow that covers earnings, and a valuation that already incorporates those improvements, making outcomes sensitive to the exit multiple applied by buyers.
The market has moved, and the filings show evidence for both stronger fundamentals and a rich valuation; that trade-off between growth and valuation helps explain the current debate.
