How Does West Pharmaceutical Services Make Money?
Proprietary Products supplies 81% of revenue, so West Pharmaceutical Services's results move mostly with that one business; the others matter more for diversification than for the headline number. Between fiscal 2024 and 2025, Proprietary Products grew fastest (+6.8%) and Contract Manufactured Products slowest (+4.2%), so the revenue mix tilts toward Proprietary Products while that gap lasts.
| Segment | FY2025 revenue | FY2024 revenue | Share of revenue | Change |
|---|---|---|---|---|
| Proprietary Products | $2.5 billion | $2.3 billion | 81.1% | 6.8% |
| Contract Manufactured Products | $582 million | $559 million | 18.9% | 4.2% |
Which West Pharmaceutical Services Segments Earn the Most?
| Segment | FY2025 segment operating income | Segment margin |
|---|---|---|
| Proprietary Products | $657 million | 26.4% |
| Contract Manufactured Products | $63 million | 10.9% |
Segment operating income is the profit measure West Pharmaceutical Services reports to its chief operating decision maker for each segment. 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 West Pharmaceutical Services more safely than against another company.

What the Segment Figures Do Not Show
The rows above add up to 100% of West Pharmaceutical Services'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 West Pharmaceutical Services reported in the segment note and revenue disclosures of its Form 10-K filed February 17, 2026 (accession 0000105770-26-000010), 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.
