New York, March 3, 2026, 14:04 ET — Regular session
Shares of UnitedHealth Group Incorporated (UNH) dropped 2.1% to $288.79 Tuesday afternoon, briefly hitting a low of $284.63 earlier in the session. The move lower came as other big U.S. health insurers also slipped: Elevance Health fell around 2.1%, Humana slid 2.9%, Cigna declined 2.7%.
Stocks struggled, Wall Street’s major indexes dropping as traders took stock of the inflation risks tied to escalating Middle East tensions and pricier energy. “Investors worry about additional inflation coming down the road,” said Robert Pavlik, senior portfolio manager at Dakota Wealth. Reuters
There’s a fresh headache for health insurers, this time from regulators. The Centers for Medicare & Medicaid Services has notified Elevance about planned sanctions—Reuters said Monday the company could see enrollment in its Medicare Advantage prescription drug plans suspended, unless CMS finds the issues resolved.
Risk adjustment, a payment structure tying higher insurer payouts to sicker members—using diagnosis codes—remains the main point of contention. Barclays analyst Andrew Mok weighed in, saying an intra-year enrollment pause probably won’t hit earnings much, but called it “a negative regulatory signal” as CMS steps up its data validation audits.

UnitedHealth moved to file a fresh automatic shelf registration Monday, opening up options to issue debt or other securities as needed, according to the filing. The company also put out its 10-K for the year ending Dec. 31, 2025, and noted a switch in chief accounting officer, effective March 2.
UnitedHealth, in its 8-K, named Dennis Stankiewicz as the new chief accounting officer. Tom Roos, who previously held that post, will move over to become chief financial officer at Optum Insight.
Large issuers regularly file shelf registrations. The move sets up a flexible structure for raising funds down the line—though on its own, it doesn’t signal that an offering is about to happen.
These filings come as investors keep a close watch on Medicare Advantage funding shifts and tighter oversight, both of which could hit managed-care earnings. UnitedHealth, back in late January, flagged its first expected revenue drop since 1989, after the government floated a nearly unchanged 2027 Medicare Advantage rate. CEO Stephen Hemsley told Reuters the company is shifting back to “financial rigor.” Reuters
Still, there’s no shortage of ways this could unravel. Persistent inflation from the energy jolt and stubbornly high yields could batter even the market’s safer bets. Should CMS decide to broaden its crackdown on risk-adjustment filings past Elevance, the sector could find itself grappling with headline risk across the board.
Eyes are fixed on Elevance’s next move, with its written rebuttal due March 10 and that looming March 31 mark when enrollment suspensions could kick in. How regulators handle this could signal just how tough they intend to get with Medicare Advantage plans.
