Earnings Analysis July 29, 2026

Amphenol ($APH) Q2 2026 Earnings Analysis — Revenue of $8.8B and Adjusted EPS of $1.35 Smash Estimates, with Q3 Guidance Also Above Consensus

Earnings Scorecard

Revenue: $8.8 billion (+55% YoY, estimate $8.332 billion) ✅ Beat

EPS: Adjusted $1.35 (+67% YoY, estimate $1.19) ✅ Beat

Guidance: Raised — Q3 revenue $9.3B–$9.4B and adjusted EPS $1.40–$1.42 guided (both roughly +50% YoY)

Stock reaction: +1.11% after-hours ($145.44) — as of 07-29 20:42 KST

The Positives

Beat own guidance: Revenue of $8.8B even surpassed the company's own outlook of $8.1B–$8.2B

Orders of $10.7B: Book-to-bill ratio of 1.23x shows backlog building faster than sales

Profitability of 29.8%: Adjusted operating margin improved sharply from 27.3% in the prior quarter

Amphenol makes connectors (interconnect components) and cables that link electronic devices with data center equipment. This quarter's revenue of $8.8 billion is up 55% versus a year ago, and even organic growth alone — excluding acquisition effects — came in at 30%. The key takeaway is that it beat the company's own $8.1B–$8.2B guidance by 6–8%. It is uncommon for the company to clear its own bar by such a wide margin, which suggests AI data center orders accelerated faster than expected during the quarter.

Orders of $10.7 billion exceeded revenue by $1.9 billion. A book-to-bill ratio of 1.23x means new orders taken this quarter were 23% higher than what was shipped and billed, indicating that the queue of revenue waiting to be converted continues to thicken going into next quarter and beyond. It is also the foundation that allowed the company to guide Q3 revenue to $9.3B–$9.4B.

Profitability improved alongside. The adjusted operating margin of 29.8% is 2.5 percentage points better than the 27.3% in Q1. Operating cash flow of $1.6B and free cash flow of $1.2B allowed the company to return $515 million to shareholders through buybacks and dividends, and it also closed the acquisitions of L-com (annual revenue of roughly $150 million) and Wilder Technologies (roughly $15 million).

The Negatives

One-time tariff refund of $80 million: Part of the margin improvement is a non-recurring item

Acquisition dependency: Roughly 25 percentage points of the 55% growth came from M&A

Concentration in AI investment cycle: If data center spending stalls, the order book will shake as well

This quarter's operating income includes a net $80 million benefit from a U.S. International Emergency Economic Powers Act (IEEPA) tariff refund. That is roughly 0.9 percentage points of revenue, meaning close to 1 percentage point of the 29.8% margin came from a non-recurring item rather than underlying business strength. If the same item does not repeat next quarter, the margin could naturally step down.

The composition of growth is also worth examining. Of the full 55% growth, 30 percentage points came from organic growth, and the rest came from the consolidation of CommScope's connectivity and cable business. The company raised its 2026 contribution guidance for that deal to $4.6 billion in revenue and a $0.30 increase in adjusted EPS, which means a substantial portion of the growth story still hinges on successful integration. Acquisition effects drop out of the comparison base after a year, so the test from next year onward will be whether organic growth alone can sustain the current pace.

Finally, the source of demand is lopsided. The IT/datacom segment already exceeded 40% of total revenue in Q1, and growth this quarter was driven by AI data center build-outs. While other markets such as automotive, industrial, and defense lend support, if the capex plans of the major cloud providers are revised, the safety net provided by $10.7 billion in orders could quickly thin out.

What the Company Said

The Q3 guidance was the most aggressive part of the release. Revenue of $9.3B–$9.4B and adjusted EPS of $1.40–$1.42 are another step up from the just-finished Q2, both representing growth of just over 50% year-over-year. Having just reported a quarter of 55% growth and then pledging to maintain a similar pace next quarter signals that management views AI-related demand as a continuing trend rather than a temporary spike, at least for now.

The language around M&A also stands out. The company lifted its 2026 contribution outlook for the CommScope connectivity and cable business to $4.6 billion in revenue and a $0.30 increase in adjusted EPS, and closed the additional acquisitions of L-com and Wilder Technologies during the quarter. The established playbook of layering M&A on top of a strong core business continues unchanged. However, given that the company itself disclosed that one-time tariff refunds were mixed into the margin improvement, some investors will want to look past the headline and assess the underlying business margin on its own rather than taking the guidance at face value.

Market Reaction and What to Watch

There is a reason the stock reaction was measured despite the impressive numbers. Amphenol had already rallied significantly as an AI beneficiary heading into the print, and the market had already priced in a substantial portion of a "beat" outcome. On top of that, part of the margin improvement came from a non-recurring tariff refund, and nearly half of the growth came from acquisitions — both of which dampened the enthusiasm. The result was digested as "good as expected" rather than "outright great."

Even so, the numbers themselves are strong. Orders of $10.7 billion and a book-to-bill of 1.23x indicate that the sketch of next quarter's revenue is already drawn, and the company's $9.3B–$9.4B Q3 guidance is built on top of that sketch. Going forward, whether this pace can be sustained, and where the underlying margin — stripping out one-time items — settles, will decide the stock's direction.

Whether Q3 actual revenue exceeds the high end of guidance at $9.4B

Whether the adjusted operating margin, excluding one-time items like tariff refunds, holds in the 29% range

Whether the book-to-bill ratio stays above 1.2x or moves closer to 1.0x

Whether the IT/datacom segment share keeps climbing, or whether other markets such as automotive and industrial provide balance
