--- title: "Ametek: Business Model & Revenue Engine" description: "Ametek revenue by business segment from its fiscal 2025 Form 10-K, with each part's share, growth and profitability explained." canonical: https://www.getswoopr.com/stocks/companies/ametek/business-model/ source: "Swoopr Investment: https://www.getswoopr.com" --- # Ametek: Business Model & Revenue Engine ## Direct Answer Ametek reports revenue across 2 business segments in its fiscal 2025 Form 10-K. Electronic Instruments Group is the largest, with $4.9 billion of revenue (66% of the total), followed by Electromechanical Group at $2.5 billion (34%). ## How Does Ametek Make Money? Electronic Instruments Group supplies 66% of revenue, so Ametek's results move mostly with that one business; the others matter more for diversification than for the headline number. Between fiscal 2024 and 2025, Electromechanical Group grew fastest (+8.8%) and Electronic Instruments Group slowest (+5.6%), so the revenue mix tilts toward Electromechanical Group while that gap lasts. | Segment | FY2025 revenue | FY2024 revenue | Share of revenue | Change | | --- | --- | --- | --- | --- | | Electronic Instruments Group | $4.9 billion | $4.7 billion | 66.5% | 5.6% | | Electromechanical Group | $2.5 billion | $2.3 billion | 33.5% | 8.8% | ![Bar chart of Ametek revenue by segment for fiscal 2025: Electronic Instruments Group 66.5%, Electromechanical Group 33.5%.](https://www.getswoopr.com/images/charts/ametek-business-model-segment-mix.webp) *Ametek 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 Ametek more safely than against another company. ## What Does Ametek Sell? Ametek also breaks revenue down by product and service line, which shows what customers pay for rather than how management organizes the business. | Product or service | FY2025 revenue | FY2024 revenue | Share of revenue | Change | | --- | --- | --- | --- | --- | | Process and Analytical Instrumentation | $3.5 billion | $3.2 billion | 46.8% | 7.2% | | Aerospace and Power | $2.2 billion | $2.1 billion | 29.6% | 6.6% | | Automation and Engineered Solutions | $1.7 billion | $1.7 billion | 23.6% | 5.6% | ## What the Segment Figures Do Not Show The rows above add up to 100% of Ametek'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 Ametek reported in the segment note and revenue disclosures of its Form 10-K filed February 17, 2026 (accession 0001037868-26-000016), 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. This page is educational and describes reported history for fiscal 2025; it is not a forecast or a recommendation. ## Frequently Asked Questions ### What are Ametek's business segments?
