UnitedHealth released $1.25bn of last year's claim reserves into first-half earnings
Q2 2026 10-Q: revenue $112.0bn (+0.4%), net earnings $5.5bn (+61%). The medical-costs-payable rollforward shows $1,250m of favorable prior-year reserve development in the first half (H1 2025: $320m) plus a $236m reduction in loss-contract reserves, both lowering medical costs. No buybacks in Q2; a $400m foundation contribution funded by the gain on selling an Optum Insight business
UnitedHealth Group (UNH) reported revenue of $112,032m for the second quarter of 2026, almost unchanged from a year earlier, and net earnings of $5,484m, up 61%. The medical-costs-payable note of the 10-Q filed on August 10 shows where the rebound came from: a release of reserves set aside for last year's claims.
In plain terms
UnitedHealth recalculated money set aside last year for medical costs and found less was needed. The difference was added to this year's profit. It is nearly four times the same item a year earlier.

FAQ
Is releasing reserves an accounting problem?
No. Adjusting estimates to actual experience is normal, and the 10-Q discloses the amount and reason (a favorable respiratory season). But the release is 3.9 times a year earlier and is a revision of last year's estimate rather than this year's operations, so it belongs to the composition of earnings. The criteria for judging it are in the subscriber section.
What are the government investigations?
The 10-Q says the company is involved in investigations, audits and reviews by agencies including CMS, the DOJ, the SEC, the FTC and Congressional committees, is responding to subpoenas and information requests, and that certain businesses are under review including for compliance with coding. It says it can give no assurance on scope, outcome or material effect. This article reports only what is disclosed.
How did net earnings rise 61% on flat revenue?
Medical costs fell $3.2bn from a year earlier ($78,585m → $75,358m) and the MCR fell 2.7 points, lifting operating earnings from $5,150m to $7,991m.
Where can I verify these numbers?
On SEC EDGAR: UnitedHealth's Q2 2026 Form 10-Q (accession 0000731766-26-000197), the Note 4 medical-costs-payable rollforward, the restructuring and other actions note, the MD&A results table and the contingencies note.
