Amphenol's Operating Margin Improves in Q1: Can It Expand Further?
Read MoreHide Full Article
Key Takeaways
Amphenol posted a 27.3% Q1 operating margin, up 380 bps year over year on strong sales growth.
APH expects Q2 revenue of $8.1B-$8.2B, driven by AI demand and CommScope acquisition benefits.
TE Connectivity and Astera Labs are intensifying competition with strong growth and margin gains.
Amphenol (APH - Free Report) delivered a strong operating margin expansion in the first quarter of 2026. The company reported a non-GAAP operating margin of 27.3% for the first quarter, indicating a 380 basis points (bps) expansion from the year-ago quarter’s 23.5%. The strong year-over-year improvement was primarily driven by higher sales volumes and a robust operating leverage.
Amphenol recorded operating margin expansion across every business segment. Growth was led by the Communications Solutions segment, where operating margin expanded 320 bps year over year to 30.6%, benefiting from strong AI infrastructure and hyperscale data center demand.
Margins also improved across the Harsh Environment Solutions and Interconnect & Sensor Systems businesses, reflecting broad-based operational strength. The operating margin for Harsh Environment Solutions increased 350 bps to 28%, while that for Interconnect and Sensor Systems grew 210 bps to 20.2%.
Looking ahead to second-quarter 2026, Amphenol expects revenues between $8.1 billion and $8.2 billion, representing a 43-45% increase over the prior-year quarter. The company also expects adjusted EPS of $1.14-$1.16, representing a 41% to 43% increase over the prior-year quarter. The guidance suggests continued healthy demand and operating leverage, which should support strong margin expansions. Benefits from the CommScope acquisition, expanding AI-related deployments and strong order momentum, reflected in a 1.24:1 book-to-bill ratio, are likely to aid profitability.
However, potential pressure from tariffs and raw material inflation could weigh on margin expansion. Still, Amphenol’s diversified end-market exposure, scale advantages and strong execution position the company well to sustain elevated operating margins in the coming quarter.

In the first quarter of 2026, Astera Labs’ revenues jumped 93% year over year to $308.4 million, while non-GAAP operating margin expanded 250 bps to 36.2%.
