How Does Coherent Corp. Make Money?
No single line supplies a majority of revenue: the largest, Networking, is 59%, which spreads Coherent Corp.'s exposure across several demand drivers. Between fiscal 2024 and 2025, Networking grew fastest (+49.0%) and Materials slowest (-6.2%), so the revenue mix tilts toward Networking while that gap lasts.

What the Segment Figures Do Not Show
The rows above add up to 100% of Coherent Corp.'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 Coherent Corp. reported in the segment note and revenue disclosures of its Form 10-K filed August 15, 2025 (accession 0000820318-25-000014), 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.
