Direct Answer
Humana reports revenue across 2 business segments in its fiscal 2025 Form 10-K. Insurance is the largest, with $125 billion of revenue (96% of the total), followed by Center Well at $22.5 billion (17%).
How Does Humana Make Money?
Insurance supplies 96% of revenue, so Humana's results move mostly with that one business; the others matter more for diversification than for the headline number. Between fiscal 2024 and 2025, Center Well grew fastest (+12.7%) and Insurance slowest (+9.5%), so the revenue mix tilts toward Center Well while that gap lasts.
| Segment | FY2025 revenue | FY2024 revenue | Share of revenue | Change |
|---|---|---|---|---|
| Insurance | $125 billion | $114 billion | 96.1% | 9.5% |
| Center Well | $22.5 billion | $19.9 billion | 17.3% | 12.7% |
Which Humana Segments Earn the Most?
| Segment | FY2025 segment operating income | Segment margin |
|---|---|---|
| Insurance | $1.7 billion | 1.3% |
| Center Well | $1.3 billion | 6.0% |
Segment operating income is the profit measure Humana 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 Humana more safely than against another company.
What the Segment Figures Do Not Show
The rows above add up to 113% of Humana'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 Humana reported in the segment note and revenue disclosures of its Form 10-K filed February 19, 2026 (accession 0000049071-26-000009), 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.
