--- title: "Amphenol: Business Model" description: "Amphenol revenue by business segment and geography from its fiscal 2025 Form 10-K, with each part's share, growth and profitability explained." canonical: https://www.getswoopr.com/stocks/companies/amphenol/business-model/ source: "Swoopr Investment: https://www.getswoopr.com" --- # Amphenol: Business Model & Revenue Engine ## Direct Answer Amphenol reports revenue across 3 business segments in its fiscal 2025 Form 10-K. Communications Solutions is the largest, with $12.2 billion of revenue (53% of the total), followed by Harsh Environment Solutions at $5.9 billion (25%). 35% of revenue came from the United States. ## How Does Amphenol Make Money? No single line supplies a majority of revenue: the largest, Communications Solutions, is 53%, which spreads Amphenol's exposure across several demand drivers. Between fiscal 2024 and 2025, Communications Solutions grew fastest (+92.3%) and Interconnect and Sensor Systems slowest (+15.6%), so the revenue mix tilts toward Communications Solutions while that gap lasts. | Segment | FY2025 revenue | FY2024 revenue | Share of revenue | Change | | --- | --- | --- | --- | --- | | Communications Solutions | $12.2 billion | $6.3 billion | 52.7% | 92.3% | | Harsh Environment Solutions | $5.9 billion | $4.4 billion | 25.5% | 33.1% | | Interconnect and Sensor Systems | $5.2 billion | $4.5 billion | 22.6% | 15.6% | ![Bar chart of Amphenol revenue by segment for fiscal 2025: Communications Solutions 52.7%, Harsh Environment Solutions 25.5%, Interconnect and Sensor Systems 22.6%.](https://www.getswoopr.com/images/charts/amphenol-business-model-segment-mix.webp) *Amphenol revenue by segment as a share of total revenue, from the table above.

It usually leaves out corporate costs that are not allocated to a segment, so the segments usually add up to more than consolidated operating income, and margins are comparable within Amphenol more safely than against another company. ## Where Does Amphenol's Revenue Come From? Regions follow the definitions in the filing; most companies assign revenue by customer location. | Region | FY2025 revenue | FY2024 revenue | Share of revenue | Change | | --- | --- | --- | --- | --- | | Other Foreign Locations | $11.4 billion | $6.6 billion | 49.5% | 74.6% | | United States | $8.0 billion | $5.3 billion | 34.6% | 51.5% | | China | $3.7 billion | $3.4 billion | 15.9% | 8.0% | ## What the Segment Figures Do Not Show The rows above add up to 101% of Amphenol's reported revenue for fiscal 2025; the difference is intersegment eliminations, corporate revenue or items the company reports outside its segments. Segment definitions are management's choice and change when a company reorganizes, in which case it restates prior years in the next filing, so a multi-year comparison should use the figures from a single filing. Revenue shows where sales come from, not where profit or cash is earned: a small segment can carry most of the margin. ## Where These Numbers Come From Every figure on this page is a value Amphenol reported in the segment note and revenue disclosures of its Form 10-K filed February 11, 2026 (accession 0001104659-26-013549), read from the SEC's Financial Statement Data Sets. The prior-year column is the comparative figure from that same filing, so it reflects any restatement for a change in segments. Category names are the company's own XBRL labels, lightly reformatted for reading. Rows that only total other rows (for example a "Products" line beside the individual products) are left out so nothing is counted twice.
