HUM, Humana Inc.
Humana is a health insurer built around Medicare, the government program for older Americans. It sells private Medicare Advantage plans, along with Medicaid coverage for lower-income members; it collects premiums, much of which the federal government pays on a per-member basis, and out of those premiums it pays members' medical claims, keeping whatever is left after claims and the cost of running the plans. Through its CenterWell arm it also delivers care to members directly rather than only paying others to provide it.

The business in brief
read the 10-K →What this business is and what moves its needle, from its own SEC filings.
- What moves the needle
- The whole game is the spread between premiums taken in and medical claims paid out, so the test is medical-cost discipline: whether Humana can price and manage care a notch better than the next insurer, on a margin too thin to absorb a bad year. The company itself concedes the barriers to entry in its markets are not substantial, which is the franchise-or-commodity question answering itself; any durable edge would have to show up in scale, in the care delivered through CenterWell, and in the quality ratings that help set what the government pays. Against that stands its dependence on federal reimbursement and on the data systems that run the business, where a shift in policy or an error at scale reaches the entire book at once. See the record below for the margins, returns, and leverage.
- Is it a good business?
- It pays out about 89% of premiums as medical care across the record (the medical loss ratio), keeping the rest to cover administration and profit against a regulated floor. That leaves a thin operating margin, a median of about 3.9%, the sign of a volume-and-cost-control business rather than a high-margin one, though turns that sliver over fast enough to earn roughly 17% on equity. Whether membership keeps growing and medical costs stay below premiums, especially as the Medicare Advantage and Medicaid mix shifts, is what the 10-K decides, not an earnings multiple.

Owner’s Scorecard
Is it a good business?
- Medical loss ratio 90.2%Costs running highMedical costs $110.8B ÷ premiums earned $122.8BIndustry peers: median 85%
What this means
The number that runs a health plan: cents of every premium dollar paid back out as medical care. A regulated floor (about 80-85% under the ACA, or rebates are owed) means the plan keeps only a thin sliver, so the discipline is in pricing premiums ahead of medical cost trend. Read it across years, because a single bad cost trend, like the recent Medicare Advantage squeeze, shows up here first.
- Operating margin 2.1%Thin, as the model runsOperating income $2.7B ÷ revenue $129.7BIndustry peers: median 4%
What this means
Health plans earn a sliver on enormous revenue, so a few points of margin is the norm and the business is really a volume-and-cost-control game. Because the margin is so thin, a small miss on medical costs swings profit hard, which is why membership scale and cost management matter more than price.
- Below the cost of equityNet income $1.2B ÷ equity $17.7BIndustry peers: median 13%
What this means
The thin margin turns over fast on a modest capital base, so a plan earning its keep still shows a good return on equity. Durably above the ~10% cost of equity is what compounds value; a year below it usually means medical costs outran premiums.
Does AI threaten the moat?
Low contestabilityThe moat is physical, regulated or balance-sheet-funded, the kind AI cuts costs within but does not contest.
The filing raises AI among its risks, but in other terms (security, regulation, energy or the like), not as a competitor to its product.
AI is unlikely to contest a moat that is physical, regulated or balance-sheet-funded; here it reads more as a cost tool than a threat.

Acquisitions & goodwill

None written down over the record; the goodwill is still carried at full cost. That is the deals holding their value on the books so far; whether they keep doing so is the test an owner watches, since the write-down, when it comes, is the admission the price was too high.

Management, ownership & pay
read the proxy →From the proxy: how much of the business the people running it own, and how they are paid, beside what the business earned for its owners in the same years.
| Fiscal year | Chief executive | Pay, as filed | “Actually paid” | Owner earnings |
|---|---|---|---|---|
| 2021 | Mr. Rechtin | $16.5M | $25.8M | $1.7B |
| 2022 | Mr. Rechtin | $17.2M | $30.4M | $3.9B |

| 2025 | Mr. Rechtin | $18.8M | $18.8M | $375M |
Both pay figures are the company’s own, from the pay-versus-performance table its proxy statement files. “As filed” is the Summary Compensation Table total: salary, bonus, and equity awards at their value on the day of grant. “Actually paid” is the SEC’s prescribed recalculation, which re-marks those equity awards to what they became as they vested; it can swing far above or below the filed figure in either direction, and negative years occur. Owner earnings are the whole business's, from the record above, for the same fiscal years.
- Insider ownership0.2%
The stake all directors and executive officers hold together, per the 2026 proxy: skin in the game, the first thing Munger reads.
- CEO pay ratio226:1
What the chief earns for every dollar the median employee makes, per the 2026 proxy. A high ratio alone settles nothing; some businesses are genuinely top-heavy in scarce skill. A runaway figure is where Buffett starts asking whether the board is doing its job.
- Stock-based compensation$241M
The slice of the business handed to employees in shares this year, 0% of revenue, equal to 9% of operating profit. Buffett's oldest accounting fight: this is compensation, compensation is an expense, real whether or not the headline earnings admit it. One trap: the cash-flow statement adds SBC back, so the operating cash, and the owner earnings drawn from it, are flattered by exactly this amount; counted as the cost it is, what an owner keeps is lower.
