Item 1.01. Entry into a Material Definitive Agreement.

On February 6, 2026, Oscar Health, Inc. (the “Company”), entered into a $475.0 million secured three-year revolving credit facility (the “Revolving Credit Facility”), pursuant to a Credit Agreement (the “Credit Agreement”), by and among the Company, certain subsidiaries of the Company, as subsidiary guarantors, JPMorgan Chase Bank, N.A., as administrative agent, and the lenders party thereto. Capitalized terms used but not defined herein have the meanings ascribed to them in the Credit Agreement. The Revolving Credit Facility expires, and any amounts outstanding thereunder will become due and payable, on February 6, 2029. The Revolving Credit Facility also contains an expansion option permitting the Company to request increases of up to an aggregate additional $100.0 million, upon the satisfaction of certain conditions.

The proceeds of the loans under the Revolving Credit Facility are available to be used for general corporate purposes. If no event of default has occurred, borrowings under the Revolving Credit Facility will initially bear interest at a rate equal to, at the Company’s option, either Term SOFR plus a margin of 4.50% per annum, or the Alternate Base Rate plus a margin of 3.50% per annum. From and after June 30, 2026, the applicable margin will be adjusted based on the Company’s Total Net Leverage Ratio, with the applicable margin for each Term SOFR loan ranging from 3.75% to 4.50%, and the applicable margin for each Alternate Base Rate loan ranging from 2.75% to 3.50%.

The Revolving Credit Facility also includes a commitment fee, initially 0.50% for available but undrawn amounts, which is payable quarterly in arrears, and other administrative fees. From and after June 30, 2026, the applicable commitment fee will be adjusted based on the Company’s Total Net Leverage Ratio and may range from 0.35% to 0.50% of available but undrawn amounts.

The Revolving Credit Facility is guaranteed by each wholly owned subsidiary of the Company, and all of the Company’s future direct and indirect subsidiaries (in each case subject to certain permitted exceptions, including exceptions for guarantees (i) that would require material governmental consents or (ii) in respect of joint ventures) (the “Guarantors” and together with the Company, the “Loan Parties”).

The Credit Agreement contains customary conditions precedent, representations and warranties, affirmative and negative covenants, events of default and indemnities. Certain changes of control with respect to the Company would constitute an event of default under the Revolving Credit Facility. Upon the occurrence and during the continuance of an event of default, the lenders may declare the outstanding advances and all other obligations under the Revolving Credit Facility immediately due and payable. Borrowings under the Revolving Credit Facility are prepayable at the Company’s option
