Every percentage point of premium increase that pushes someone off a health insurance exchange has a destination. That destination, as HCA Healthcare’s results this morning make clear, is an unpaid hospital bill.
HCA, the country’s largest for-profit hospital operator with roughly $78 billion in trailing revenue, reported Q3 2026 results before the open today. Analysts had expected earnings per share of $6.63, a 4.7% decline year-over-year, on revenue of $19.33 billion. That expected earnings drop, modest as it sounds, tells a specific and consequential story about what happens to hospital economics when insurance coverage unravels at scale.
The Bigger Trend
The backdrop could not be more pointed. Average Marketplace premiums are rising roughly 15% for 2027, a second consecutive year of steep increases.
Enhanced premium subsidies remain expired following their end-of-2025 sunset, and the cliff is still in place unless Congress moves.
Total exchange enrollment has dropped to 23.1 million, a 5% decrease from 2025, and average out-of-pocket premium payments rose 58% from $113 to $178 per month in 2026, according to KFF’s analysis of CMS and state Marketplace data. Those aren’t abstractions. Those are patients who show up at HCA’s emergency departments and leave without a bill that gets paid.
The Investment Case
The mechanism HCA’s own executives identified this year is blunt. HCA Healthcare told analysts that patients who dropped off marketplace plan coverage due to increased premiums have “migrated almost one for one” to uninsurance. CFO Mike Marks told investors the company had expected 80% to 85% of patients losing exchange coverage to become uninsured, but the real figure is closer to one-for-one. That single miscalculation reset the company’s full-year math.
The expiration of enhanced tax credits is pushing patients into uninsured status, with an estimated full-year impact of more than $1 billion and slower elective-care utilization. Against that, during Q2 the company recognized approximately $400 million of incremental net benefit from Medicaid Supplemental Payment Programs, primarily related to the state of Florida for the time period October 1, 2024 through June 30, 2026. That Florida windfall does not repeat in Q3, making today’s year-over-year comparison structurally harder than the headline number suggests.
Same-facility admissions increased 2.5% and same-facility equivalent admissions were up 2.7%, but same-facility inpatient surgeries declined 2.3% and same-facility outpatient surgeries were down 3.4% during Q2 2026. Surgery volumes are where hospitals make their margins. Admissions keep the lights on; elective procedures pay for the rest.
HCA’s underperformance was primarily driven by a worsening payer mix, as individuals lost coverage through health insurance exchanges following the expiration of Affordable Care Act subsidies, leading to sharp declines in high-margin elective inpatient and outpatient surgeries. Peer operators confirmed the same dynamic. Universal Health Services’ CFO Steve Filton said: “It felt like virtually everyone who lost their exchange coverage became an uninsured patient.”
Building Wealth Around This Idea
For long-term investors, HCA presents a genuine tension.
The trailing P/E ratio of 15.63x sits modestly above its five-year median of 14.16x, which is not cheap for a business absorbing a billion-dollar headwind from a policy decision Washington has not reversed. Tenet Healthcare (THC) and Universal Health Services (UHS) carry similar exposure. Managed care names like Centene (CNC) and Elevance (ELV) face the same coverage-loss environment from the other side: fewer enrolled members, sicker remaining pools, rising medical loss ratios.
The managed care side of this equation is also contracting. UnitedHealth is deliberately exiting counties and discontinuing plans rather than absorb members whose cost profile it cannot manage.
The diversified hospital sector is not uninvestable here. Long-term volume growth targets remain at 2% to 3% CAGR, supported by capital investments and network optimization across 43 markets. An aging population and structural demand for inpatient care don’t disappear because exchange subsidies expired. But the upside depends heavily on whether premiums stabilize and whether Congress acts before a second 15% increase locks another cohort out of coverage permanently.
Risks to Monitor
There is “little chance” that a large number of those uninsured patients will regain ACA exchange coverage or find employer-sponsored insurance, which will continue to impact profitability, said Ryan Langston, a director and senior analyst at TD Cowen. That assessment, if accurate, means the current uncompensated care load is not cyclical. It is structural, at least until policy changes.
Total uncompensated care was $15.076 billion for the quarter ended June 30, 2026, compared to $11.625 billion in the same quarter of 2025, with estimated costs rising from $1.116 billion to $1.445 billion. If Q3 carries a similar trajectory, the cost of care HCA absorbs but cannot collect on continues compounding.
Daily Wealth Takeaway
Policy risk is not something that happens to bonds and utility stocks. Today’s HCA quarter is a real-time demonstration that health insurance legislation directly changes hospital earnings. When evaluating any hospital operator, the question to ask is not just “are admissions growing?” but “who is paying for them?” The answer, right now, is increasingly: no one.
