Notes to Condensed Consolidated Financial Statements (unaudited)

(in thousands, except per share amounts, or as otherwise stated herein)

1. ORGANIZATION

Oscar Health, Inc., together with its subsidiaries (either individually or collectively referred to as “Oscar” or the “Company”), is a leading healthcare technology company, whose mission is to make a healthier life accessible and affordable for all. The Company’s Class A common stock is traded on the New York Stock Exchange under the symbol “OSCR”.

Oscar operates as one reportable segment to sell insurance to individuals, families, and employees through the federal and state-run healthcare exchanges formed in conjunction with the Patient Protection and Affordable Care Act (“ACA”) and leverages its technology platform to provide services via its +Oscar offering. In May 2025, the Company purchased 100% of the equity interests in three businesses operating in the individual market: INSXCloud, Inc. (an approved enhanced direct enrollment platform), IHC Specialty Benefits, Inc. (an insurance agency that sells individual medical and supplemental health products), and Healthinsurance.org, LLC (an online resource providing educational content for consumers navigating health insurance and the ACA marketplace). The Company determined that the Chief Executive Officer is the chief operating decision maker (“CODM”) who regularly reviews financial information and other key performance indicators on a consolidated basis, for the purposes of allocating resources and evaluating financial performance. Factors used in determining the reportable segment include the nature of operating activities, the Company’s organizational and reporting structure, and the type of information presented to the Company’s CODM to allocate resources and evaluate financial performance.

The Company’s member-first philosophy and innovative approach to care has earned the trust of approximately 2.1 million effectuated members (“members”), as of September 30, 2025. Effectuated members are those who are actively enrolled in one of the Company’s plans and whose required premium payments have either been made or are within the payment grace period.

Basis of Presentation

The accompanying interim Condensed Consolidated Financial Statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”), and the applicable rules and regulations of the Securities and Exchange Commission for interim financial information. As such, these financial statements do not include all information and footnotes required by U.S. GAAP for complete financial statements.

These Condensed Consolidated Financial Statements are unaudited; however, in the opinion of management, they reflect all adjustments, consisting only of normal recurring adjustments, necessary to state fairly the information presented in conformity with U.S. GAAP applicable for the interim periods presented. The results of operations for the interim periods presented are not necessarily indicative of results for the full year or future periods. These unaudited Condensed Consolidated Financial Statements should be read in conjunction with the audited Consolidated Financial Statements and related notes thereto included in the Company’s Annual Report on Form 10-K filed with the Securities and Exchange Commission for the year ended December 31, 2024.

During the second quarter of 2025, management identified an understatement of Selling, general, and administrative (“SG&A”) expenses related to the 2023-2024 periods. In accordance with Staff Accounting Bulletin ("SAB") No. 99, Materiality, and SAB No. 108, Considering the Effects of Prior Year Misstatements with Quantifying Misstatements in Current Year Financial Statements, the Company evaluated the error and determined that the out of period adjustment was not material to the consolidated financial statements for the current interim period or to any previously reported annual or interim periods. Accordingly, the Company recorded a $14.9 million adjustment in the second quarter of 2025 within SG&A expenses related to prior periods. Certain monetary amounts, percentages, and other figures included in this Quarterly Report on Form 10-Q have been subject to rounding adjustments. Percentage amounts included in this Quarterly Report on Form 10-Q have not in all cases been calculated on the basis of such rounded figures, but on the basis of such amounts prior to rounding. For this reason, percentage amounts in this Quarterly Report on Form 10-Q may vary from those obtained by performing the same calculations using the figures in the Company's Condensed Consolidated Financial Statements included elsewhere in this Quarterly Report on Form 10-Q. Certain other amounts that appear in this Quarterly Report on Form 10-Q may not sum due to rounding.

Table of Contents

Use of Estimates

The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported in the Condensed Consolidated Financial Statements and accompanying notes. Significant estimates inherent in the preparation of the accompanying interim Condensed Consolidated Financial Statements include healthcare costs incurred but not yet reported (“IBNR”) and risk adjustment transfers. Estimates are based on past experience, evaluation of current trends, information from third-party professionals, and other considerations that are reasonable under the circumstances. Actual results may differ materially from these estimates.

Accounting Pronouncements - Not Yet Adopted

In December 2023, the FASB issued Accounting Standards Update No. 2023-09 (“ASU 2023-09”), Income Taxes (Topic 740): Improvements to Income Tax Disclosures, which is intended to improve the transparency of income tax disclosures by requiring greater disaggregation of income tax disclosures related to the income tax rate reconciliation and income taxes paid and other amendments to improve the effectiveness of income tax disclosures. This guidance is effective for annual periods beginning after December 15, 2024, with early adoption permitted. ASU 2023-09 applies on a prospective basis; however, retrospective application in all prior periods presented is permitted. The Company plans to apply the disclosure requirements on a retrospective basis upon adoption. While the standard will require additional disclosures related to the Company’s income taxes for 2025 and prior periods included in our consolidated financial statement disclosures, the standard is not expected to have any material impact on the Company’s consolidated operating results, financial condition, or cash flows.

In November 2024, the FASB issued Accounting Standards Update No. 2024-03 (“ASU 2024-03”), Income Statement-Reporting Comprehensive Income-Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses, which requires additional disclosures in the Notes to Condensed Consolidated Financial Statements, disaggregating specific expense categories for relevant income statement captions and additional disclosures of the Company's total amount of selling expenses. This guidance is effective for annual periods beginning after December 15, 2026 and interim periods beginning after December 15, 2027, with early adoption permitted. While the standard will require additional disclosures related to the Company’s income statement, the standard is not expected to have any material impact on the Company’s consolidated operating results, financial condition, or cash flows. The Company is currently evaluating the impact of the adoption of this guidance on the related disclosures.

In September 2025, the FASB issued Accounting Standards Update No. 2025-06 (“ASU 2025-06”), Intangibles–Goodwill and Other – Internal-Use Software (Subtopic 350-40): Targeted Improvements to the Accounting for Internal-Use Software, which modernizes the recognition and disclosure framework for internal-use software costs, removing all references to “development stages” and introducing a more judgement-based approach. This guidance is effective for annual periods beginning after December 15, 2027, and interim periods within those annual reporting periods. This ASU is applicable to the Company’s fiscal year beginning January 1, 2028, with early application permitted. The transition method may be prospective, modified, or retrospective. The Company is currently evaluating the impact of the adoption of this guidance on the Company’s consolidated financial statements and disclosures.

2. EARNINGS PER SHARE

Basic earnings per share (“EPS”) is computed by dividing Net income (loss) attributable to Oscar Health, Inc. for the period by the weighted-average shares of common stock outstanding during the period.

In periods when the Company is in a net loss position, potentially dilutive securities are excluded from the computation of diluted EPS because their inclusion would have an anti-dilutive effect; thus, basic EPS is the same as diluted EPS.

During periods of net income, diluted EPS is computed by adjusting Net income attributable to Oscar Health, Inc. for any interest charges, net of tax, related to the Company’s convertible notes, as well as for the changes in the fair value of the bifurcated conversion option to the extent these instruments are dilutive. This adjusted net income is then divided by the sum of the basic weighted-average shares of common stock outstanding and any dilutive potential common stock outstanding during the period, using the treasury stock method and the if-converted method for convertible senior notes, as described in “Note 8 - Debt.” Potential common stock includes the effect of outstanding dilutive stock options, restricted stock units, and performance-based restricted stock units. The computations for basic and diluted EPS are as follows:

Shares underlying convertible notes (Note 8)	53,173	36,653	53,173	—
Total	83,041	78,844	83,041	1,660

The Company entered into capped call transactions in connection with the 2030 Notes (as defined in “Note 8 - Debt”). The effect of the capped call transactions was excluded from the calculation of diluted earnings per share as the effect of the capped calls would have been anti-dilutive. The capped calls are generally expected to reduce the potential dilution to the Company’s common stock upon any conversion of the relevant series of the Notes (See “Note 8 - Debt” for further details).

3. REVENUE RECOGNITION

Premium

Premium revenue includes direct policy premiums collected from members and the federal government, assumed policy premiums received as part of the reinsurance arrangement under the Cigna+Oscar Small Group plan previously offered, and risk adjustment transfers. Premium revenue is net of ceded premium from excess of loss (“XOL”) and run-off quota share reinsurance contracts accounted for under reinsurance accounting (See “Note 9 - Reinsurance” for additional information on the Company’s reinsurance contracts).


	Three Months Ended September 30,				Nine Months Ended September 30,
(in thousands)	2025		2024		2025		2024
Direct policy premiums	$	3,646,308	$	2,687,883	$	10,478,743	$	7,542,098
Assumed premiums	8,246		55,062		46,302		173,134
Risk adjustment transfers	(727,538)		(374,828)		(1,793,532)		(1,077,121)

Reinsurance premiums ceded	(3,048)		140		(8,280)		(12,056)
Premium	$	2,923,968	$	2,368,257	$	8,723,233	$	6,626,055

The direct policy premiums received from the Centers for Medicare & Medicaid Services (“CMS”) for the three and nine months ended September 30, 2025 were $3,391.9 million and $9,779.0 million, respectively. For the three and nine months ended September 30, 2024, direct policy premiums received from CMS were $2,488.4 million and $6,952.3 million, respectively.

Other Revenues

Other revenues include revenue earned through brokerage, enhanced direct enrollment platform, and market education services, fees for services performed via the +Oscar platform, revenue sharing from virtual credit card rebates, and sublease income. Other revenue is recognized in the period the contractual performance obligations are satisfied and measured in an amount that reflects the consideration the Company expects to be entitled to in exchange for performing the services. The timing of the Company's revenue recognition may differ from the timing of payment by customers. A receivable is recorded to Premiums and accounts receivable when revenue is recognized prior to payment and there is an unconditional right to payment. Alternatively, deferred revenue is recorded to Accounts payable and other liabilities when payment is received before the performance obligations are satisfied.

4. INVESTMENTS

Total	301	$	877,287	$	(9,802)	6	$	47,748	$	(25)

The Company monitors available-for-sale debt securities for credit losses and recognizes an allowance for credit losses when factors indicate a decline in the fair value of a security is credit-related. Certain investments may experience a decline in fair value due to changes in market interest rates, changes in general economic conditions, or a deterioration in the credit worthiness of a security's issuer. For securities in an unrealized loss position that the Company does not intend to sell, the Company has assessed the gross unrealized losses during the period and determined an allowance for credit losses is not necessary because the declines in fair value are believed to be due to market fluctuations and not due to credit-related events.

5. FAIR VALUE MEASUREMENTS

Fair value represents the price that would be received to sell an asset, or paid to transfer a liability, in an orderly transaction between market participants. The Company's financial assets and liabilities measured at fair value on a recurring basis are categorized into a three-level fair value hierarchy based on the priority of the inputs used in the fair value valuation technique.

The levels of the fair value hierarchy are as follows:

•Level 1: Inputs utilize quoted (unadjusted) prices in active markets for identical assets or liabilities.

•Level 2: Inputs utilize quoted prices for similar instruments in active markets; quoted prices for identical or similar instruments in markets that are not active; or model-derived valuations in which all significant inputs are observable in active markets.

•Level 3: Inputs utilized are unobservable but significant to the fair value measurement for the asset or liability. The unobservable inputs are used to measure fair value to the extent relevant observable inputs are not available. The unobservable inputs typically reflect management’s own estimates about the assumptions a market participant would use in pricing the asset or liability.

The following tables summarize fair value measurements by level for assets and liabilities measured at fair value on a recurring basis:

7. BENEFITS PAYABLE

Reserves for medical claims expenses are estimated using actuarial assumptions and recorded as Benefits payable liabilities on the Condensed Consolidated Balance Sheets. The assumptions for the estimates and for establishing the resulting liability are reviewed and any adjustments to reserves are reflected in the Condensed Consolidated Statements of Operations in the period in which the estimates are updated.

The following table provides a rollforward of the Company’s beginning and ending benefits payable and claims adjustment expenses (“CAE”) payable balances for the nine months ended September 30, 2025 and 2024:


	Nine Months Ended September 30, 2025						Nine Months Ended September 30, 2024

Amounts incurred related to prior periods vary from previously estimated liabilities as more claim information becomes available and claims are ultimately settled. The favorable prior period development recognized in the nine months ended September 30, 2025 resulted primarily from lower than expected paid claims for 2024.

8. DEBT

Convertible Senior Notes

As previously disclosed in “Note 9 - Debt,” in the Company’s Annual Report on Form 10-K for the year ended December 31, 2024, in February 2022, the Company issued $305.0 million in aggregate principal amount of convertible senior notes due 2031 (the “2031 Notes”) in a private placement to funds affiliated with or advised by Dragoneer Investment Group, LLC, Thrive Capital, LionTree Investment Management, LLC, and Tenere Capital LLC (the “Initial Purchasers”). In connection with the issuance of the 2031 Notes, on January 27, 2022, the Company entered into an investment agreement with the Initial Purchasers (the “Investment Agreement”) and on February 3, 2022, the Company entered into an indenture with U.S. Bank, as Trustee (the “2031 Indenture”). On September 11, 2025, the Company entered into an amendment to the Investment Agreement to permit the private offering of the 2030 Notes (as defined below) under the Investment Agreement.

The 2031 Notes are the Company's senior, unsecured obligations which bear interest at a rate of 7.25% per annum, payable in cash, semi-annually in arrears on June 30 and December 31 of each year, commencing on June 30, 2022. The 2031 Notes will mature on December 31, 2031, subject to earlier repurchase, redemption, or conversion.

Table of Contents

Upon the occurrence of a fundamental change (as defined in the 2031 Indenture), holders of the 2031 Notes have the right to require the Company to repurchase all or some of their 2031 Notes for cash, subject to certain conditions. The repurchase price will be equal to the principal amount of the notes to be repurchased, plus accrued and unpaid interest, if any, to, but excluding, the applicable repurchase date. Additionally, the initial purchasers of the 2031 Notes have the right to require the Company to repurchase all of their 2031 Notes for cash, on each of June 30, 2027, June 30, 2028, June 30, 2029 and June 30, 2030, subject to certain notice requirements.

The Company may not redeem the 2031 Notes before December 31, 2026. The Company may redeem all of the 2031 Notes from December 31, 2026 to the 35th scheduled trading day before the maturity date, at the redemption price. To do so, the last reported sale price per share of Class A common stock must have exceeded 200% of the conversion price for 20 of the last 30 consecutive trading days immediately before the date on which the Company sends the applicable redemption notice. The redemption price will be a cash amount equal to the principal amount of the 2031 Notes to be redeemed, plus accrued and unpaid interest, if any, to, but excluding, the redemption date. If the Company calls any of the 2031 Notes for redemption, the Initial Purchasers may elect to convert their 2031 Notes and receive shares of Class A common stock pursuant to the terms of the Investment Agreement.

The 2031 Notes are initially convertible into the Company's Class A common stock at a price of approximately $8.32 per share of Class A common stock (based on an initial conversion rate of 120.1721 per $1,000 principal amount), subject to customary adjustments upon the occurrence of certain events. The holders may elect to convert their 2031 Notes: (i) on or after August 31, 2031, (ii) if the Company calls the 2031 Notes for redemption, (iii) upon satisfaction of a Class A common stock sale price condition, (iv) upon satisfaction of a 2031 Note trading price condition, or (v) upon certain corporate events. Upon conversion, the Company may choose to settle the 2031 Notes in shares of Class A common stock, cash, or a combination of both, unless an Initial Purchaser of the 2031 Notes elects to receive shares of Class A common stock pursuant to the terms of the Investment Agreement. During the quarterly period ended September 30, 2025, the Class A common stock sales price condition was satisfied because the last reported sales price per share of the Company’s common stock exceeded 130% of the conversion price of $8.32 per share for twenty (20) trading days of the thirty (30) consecutive trading days ending on the last trading day of the quarter. As a result, the holders may elect to convert their 2031 Notes during the fourth quarter of 2025.

In October 2025, the Company received conversion notices from certain of the Initial Purchasers to convert a total of $20.0 million in aggregate principal amount of the 2031 Notes. The Company elected to issue approximately 2.4 million shares of Class A common stock to settle these conversions.

On November 3, 2025, the Company and Oasis FD Holdings, LP (“Dragoneer”) entered into an Exchange Agreement (the “Exchange Agreement”) pursuant to which, until December 14, 2025, Dragoneer may elect to exchange up to $250,000,000 aggregate principal amount of the 2031 Notes, representing the balance of its 2031 Notes, for aggregate consideration consisting of (A) a number of shares of Class A common stock based on the conversion rate set forth in the 2031 Indenture, and (B) up to $17.8 million, payable in shares of Class A common stock and/or cash, pursuant to the terms of the Exchange Agreement and subject to the satisfaction of certain conditions. On November 5, 2025, Dragoneer exchanged $187,500,000 aggregate principal amount of the 2031 Notes in exchange for 23,273,179 shares of Class A common stock.

In connection with the Exchange Agreement and the related transactions, as of November 5, 2025, the debt covenants in the Investment Agreement were extinguished, and the 2030 Notes (as defined below) ceased to be subordinated to the 2031 Notes.

Convertible Senior Subordinated Notes

On September 18, 2025, the Company issued $410.0 million aggregate principal amount of convertible senior subordinated notes due 2030 (the “2030 Notes”). The 2030 Notes were issued pursuant to an indenture (the “2030 Indenture”), dated as of September 18, 2025, between the Company and U.S. Bank Trust Company, National Association, as trustee.

The 2030 Notes are the Company’s unsecured subordinated indebtedness which bear interest at a rate of 2.25% per annum, payable semi-annually in arrears on March 1 and September 1 of each year, beginning on March 1, 2026. The 2030 Notes will mature on September 1, 2030, unless they are earlier repurchased, redeemed, or converted.

Table of Contents

Upon the occurrence of a fundamental change (as defined in the 2030 Indenture), holders of the 2030 Notes may require the Company to repurchase their 2030 Notes for cash, subject to certain conditions. The repurchase price will be equal to the principal amount of the 2030 Notes to be repurchased, plus accrued and unpaid interest to, but excluding, the repurchase date.

The Company may redeem the 2030 Notes, in whole or in part (subject to certain limitations described below), from September 6, 2028 to the 25th scheduled trading day before the maturity date. To do so, (i) the 2030 Notes must be freely tradable (as defined in the 2030 Indenture) as of the date of the redemption notice, the Company must be current in its interest payment obligations to the 2030 Notes holders; and (ii) the last reported sale price per share of the Company’s Class A common stock must have exceeded 130% of the conversion price on (1) 20 of the last 30 consecutive trading days immediately before the date the Company sends the applicable redemption notice; and (2) the trading day immediately before the date the Company sends such redemption notice. The Company may only redeem less than all of the outstanding 2030 Notes if at least $100.0 million aggregate principal amount of 2030 Notes are outstanding (and not called for redemption) when the Company sends the redemption notice. The redemption price will be a cash amount equal to the principal amount of the 2030 Notes to be redeemed, plus accrued and unpaid interest, if any, to, but excluding, the redemption date. Calling any 2030 Note for redemption will constitute a make-whole fundamental change (as defined in the 2030 Indenture) with respect to that 2030 Note, so the conversion rate for that 2030 Note will be increased in certain circumstances if it is converted after it is called for redemption.

Before June 1, 2030, noteholders may only convert their 2030 Notes upon the occurrence of certain events. From June 1, 2030 until the second scheduled trading day before the maturity date, noteholders may elect to convert their 2030 Notes at any time. The Company may choose to settle conversions in cash, shares of its Class A common stock, or a combination of both. The initial conversion price is approximately $24.82 per share of the Company’s Class A common stock (based on an initial conversion rate of 40.2946 shares of the Company’s Class A common stock per $1,000 principal amount of 2030 Notes). The conversion rate and conversion price are subject to customary adjustments upon the occurrence of certain events. In addition, if certain make-whole fundamental changes occur, the conversion rate will, in certain circumstances, be increased for a specified period of time.

The following is a summary of net carrying amounts and the estimated fair values of the Company’s convertible notes:


	2030 Notes				2031 Notes

Capped Call Transactions

The Capped Call Transactions cover the aggregate number of shares of the Company’s Class A common stock that initially underlie the 2030 Notes (subject to customary anti-dilution adjustments), and are expected to reduce potential dilution to the Company’s Class A common stock upon any conversion of 2030 Notes and/or offset any cash payments the Company is required to make in excess of the principal amount of converted 2030 Notes, with such reduction and/or offset subject to a cap, based on the cap price of the Capped Call Transactions. The cap price of the Capped Call Transactions is initially $37.46 per share (subject to adjustment under the terms of the Capped Call Transactions), which represents a premium of 100% over the last reported sale price of the Company’s Class A common stock on September 15, 2025. The cost of the Capped Call Transactions was approximately $34.4 million.

For accounting purposes, the Capped Call Transactions are separated from the 2030 Notes. As the Capped Call Transactions qualify for a scope exception from derivative accounting for instruments that are both indexed to the issuer’s own stock and classified in stockholders’ equity, the premiums paid for the purchase of the Capped Call Transactions are recorded as a reduction to additional paid-in capital. The Capped Call Transactions will not be remeasured as long as they continue to meet the conditions for equity classification.

Revolving Credit Facility

As previously disclosed in “Note 9 - Debt,” in the Company’s Annual Report on Form 10-K for the year ended December 31, 2024, on December 28, 2023, the Company entered into a third amendment to its senior secured credit agreement with Wells Fargo Bank, National Association, as lender and administrative agent, and certain other lenders party thereto from time to time (collectively, the “Lenders”), and Oscar Management Corporation, as a subsidiary guarantor, which amended the senior secured credit agreement, dated as of February 21, 2021 (as previously amended by the First Amendment to Credit Agreement, dated as of January 27, 2022 and the Second Amendment to Credit Agreement, dated as of July 21, 2023, the “Amended Credit Agreement”). The Amended Credit Agreement provided for a revolving loan credit facility (the “Revolving Credit Facility”) in the aggregate principal amount of $115.0 million, with proceeds to be used for general corporate purposes of the Company. On September 18, 2025, the Company terminated the Revolving Credit Facility. At the time of termination, there were no outstanding borrowings under the Revolving Credit Facility.

9. REINSURANCE

The Company participates in quota share reinsurance to limit risk and capital requirements and XOL reinsurance to mitigate the exposure of high cost or catastrophic member risk. The quota share reinsurance arrangements are with more than one counterparty with multiple state-level treaties. The XOL reinsurance arrangements are with a private counterparty and federal and state-run programs. A summary of the Company's reinsurance agreements and related accounting treatment is included in “Note 11 - Reinsurance,” in the Company’s Annual Report on Form 10-K for the year ended December 31, 2024.

As previously disclosed in “Note 1 - Organization,” in the Company’s Annual Report on Form 10-K for the year ended December 31, 2024, the Company did not renew the Cigna+Oscar Small Group arrangement after the expiration of the initial term on December 31, 2024, and will continue to provide transition and run-off services through December 31, 2026, and share proportionally in all premiums and claims for any Cigna+Oscar Small Group plan sold or issued on or before December 15, 2024, in accordance with the terms of the arrangement.

Reinsurance Contracts Accounted for under Deposit Accounting

As of September 30, 2025 and December 31, 2024, a deposit liability balance of $93.6 million and $13.6 million, respectively, was recorded for the Company's quota share arrangements accounted for under deposit accounting and represented fees due to the reinsurer, which are recognized within Selling, general, and administrative expenses on the Consolidated Statements of Operations.

For the three and nine months ended September 30, 2025, the Company ceded 47% and 49%, respectively, of its premium under reinsurance contracts accounted for under deposit accounting. For the three and nine months ended September 30, 2024, the Company ceded 51% and 53%, respectively, of its premium under reinsurance contracts accounted for under deposit accounting.

Reinsurance Contracts Accounted for under Reinsurance Accounting

In the current year, reinsurance accounting applies to XOL treaties. In 2024, reinsurance accounting also applied to quota share reinsurance contracts that were in runoff. The tables below present information for the Company's reinsurance arrangements accounted for under reinsurance accounting. Please see “Note 3 - Revenue Recognition” for total reinsurance premiums ceded and reinsurance premiums assumed, which are included as components of total Premium revenue in the Condensed Consolidated Statements of Operations.

Credit Ratings

The financial condition of the Company's reinsurers is regularly evaluated to minimize exposure to significant losses. A key credit quality indicator for reinsurance is the financial strength ratings issued by the credit rating agencies, which provide an independent opinion of a reinsurer’s ability to meet ongoing obligations to policyholders. The Company’s reinsurers have most recently been issued financial strength ratings of A+ or higher.

Table of Contents

The creditworthiness of each reinsurer is evaluated in order to assess counterparty credit risk and estimate an allowance for expected credit losses on the Company's reinsurance recoverable balances.

10. BUSINESS ARRANGEMENTS

Variable Interest Entities

The Company entered into business arrangements with integrated health systems, as well as medical professional corporations that employ health care providers to deliver telemedical healthcare services to its covered member population in various states. The financial results of these entities are consolidated into the Company's financial statements.

The following table presents the collective assets and liabilities of the Company's variable interest entities:

11. RELATED PARTY TRANSACTIONS

In February 2022, the Company issued the 2031 Notes to funds affiliated with, among others, Thrive Capital (collectively, the “Initial Purchasers”). See “Note 8 - Debt” for additional information. In addition, pursuant to the Investment Agreement entered into with the Initial Purchasers, the Company agreed to amend the Twelfth Amended and Restated Investors' Rights Agreement dated as of March 5, 2021 (the “Investors’ Rights Agreement”), by and among the Company and the investors party thereto, to provide that the Notes and shares of Class A common stock issued or issuable upon conversion of any 2031 Notes held by entities affiliated with Thrive Capital will be subject to the registration rights contained in the Investors' Rights Agreement. On September 11, 2025, the Company entered into an amendment to the Investment Agreement to permit the private offering of the 2030 Notes.

12. COMMITMENTS AND CONTINGENCIES

The Company’s current and past business practices are subject to review or other investigations by various state insurance and healthcare regulatory authorities and other state and federal regulatory authorities. These reviews focus on numerous facets of the Company’s business, including claims payment practices, statutory capital requirements, provider contracting, risk adjustment, competitive practices, commission payments, privacy issues, network adequacy, utilization management practices, pharmacy benefits, access to care, and sales practices, among others. Some of these reviews have historically resulted in fines imposed on the Company and some have required changes to certain of the Company’s practices. The Company continues to be subject to these reviews, which could result in additional fines or other sanctions being imposed on the Company or additional changes to certain of its practices.

The Company is also currently involved in, and may in the future from time to time become involved in, legal proceedings and other claims in the ordinary course of its business, including class actions and suits brought by the Company’s members, providers, commercial counterparties, employees, and other parties relating to the Company’s business, including management and administration of health benefit plans and other services. Such matters can include claims relating to the performance of contractual and non-contractual obligations to providers, vendors, members, employer groups, and others, including, but not limited to, the alleged failure to properly pay in-network and out-of-network claims and challenges to the manner in which the Company processes claims, disputes regarding the amounts owed under vendor contracts, various employment claims, disputes regarding reinsurance arrangements, disputes relating to intellectual property privacy, the Telephone Consumer Protection Act and class action lawsuits, or other and claims alleging that the Company has engaged in unfair business practices.

In addition, on May 12, 2022, a securities class action lawsuit against the Company, certain of its directors and officers, and the underwriters that participated in the Company’s initial public offering (“IPO”) was commenced in the United States District Court for the Southern District of New York (the “Court”), captioned Carpenter v. Oscar Health, Inc., et al., Case No. 1:22-CV-03885 (S.D.N.Y.) (the “Securities Action”). The initial complaint in the Securities Action asserted violations of Sections 11 and 15 of the Securities Act based on the Company’s purported failure to disclose in its IPO registration statement growing COVID-19 testing and treatment costs, the impact of significant Special Enrollment Period membership,

and risk adjustment data validation results for 2019 and 2020. By Court orders dated September 27, 2022 and December 13, 2022, the Court appointed a lead plaintiff and lead counsel on behalf of the putative class. An amended complaint filed on December 6, 2022 asserted the same violations of Sections 11 and 15 of the Securities Act, but this time based on the Company’s alleged failure to disclose in its IPO registration statement purportedly inadequate controls and systems in connection with the risk adjustment data validation audit for 2019, alleging that this purported omission caused losses and damages for members of the putative class. The amended complaint sought unspecified compensatory damages as well as interest, fees, and costs. On April 4, 2023, the Company moved to dismiss the amended complaint. On March 6, 2025, the Court granted the motion to dismiss without prejudice and granted leave to file a second amended complaint. A second amended complaint was not timely filed and on April 22, 2025 the Court dismissed the case with prejudice.

The Company records liabilities for its reasonable estimates of probable losses resulting from these matters where appropriate. Estimates of losses resulting from legal and regulatory matters involving the Company are inherently difficult to predict, particularly where the matters: involve indeterminate claims for monetary damages or may involve fines, penalties or punitive damages; present novel legal theories or represent a shift in regulatory policy; involve a large number of claimants or regulatory bodies; are in the early stages of the proceedings; or could result in a change in business practices. Accordingly, the Company is often unable to estimate the losses or ranges of losses for those matters where there is a reasonable possibility or it is probable that a loss may be incurred, the ultimate settlement of which could be material.

Given that such proceedings are subject to uncertainty, there can be no assurance that such legal proceedings, either individually or in the aggregate, will not have a material adverse effect on Oscar's business, results of operations, financial condition or cash flows.

The ACA originally established a cost-sharing reduction (“CSR”) program to make health insurance more affordable for eligible individuals by requiring insurers to reduce out-of-pocket costs while receiving CSR subsidies from CMS. In 2017, the Trump Administration issued an executive order that immediately ceased payments of ACA CSR subsidies to issuers. A class action lawsuit was subsequently filed by impacted issuers seeking compensation for the halted CSR subsidy payments. In 2024, an agreement in principle was reached between class counsel on behalf of impacted issuers and the federal government to retroactively compensate the class. In 2025, Oscar was notified of the proposed settlement amounts for each of its impacted subsidiaries. The estimated net recovery recorded as of September 30, 2025 was $49 million.

13. SEGMENT INFORMATION

The Company operates in and reports as a single reportable segment, as the CODM does not evaluate profitability nor evaluate performance or allocate resources below the level of the consolidated Company. The accounting policies of the segment are the same as those described in “Note 2 - Summary of Significant Accounting Policies,” in the Company’s Annual Report on Form 10-K for the year ended December 31, 2024. The CODM reviews Net income (loss) attributable to Oscar Health, Inc. and Earnings from operations presented on a consolidated basis for purposes of allocating resources and evaluating financial performance. These metrics serve as benchmarks to evaluate the business, measure performance, identify trends, prepare financial projections, and make strategic decisions. The CODM does not evaluate performance or allocate resources based on segment assets data; therefore, total segment assets are not presented.

The following table presents the revenue, significant expenses, and net income (loss) for the Company’s segment. As the Company operates and reports as a single segment, its measure of segment net income (loss) is the same as Net income (loss) attributable to Oscar Health, Inc. on the Condensed Consolidated Statements of Operations.

Significant Customers

The Company generates the majority of its total revenue from health insurance policy premiums, which primarily comes from subsidies received from CMS as part of the Advanced Premium Tax Credit program.

14. RISK ADJUSTMENT

The risk adjustment programs in the markets the Company serves are administered federally by CMS and are designed to mitigate the potential impact of adverse selection and provide stability for health insurers. Under this program, each plan is assigned a risk score based upon demographic information and current year claims information related to its members. Plans with lower than average risk scores generally pay into the pool (a payable to CMS), while plans with higher than average risk scores generally receive distributions (a receivable from CMS). The Company estimates its risk adjustment transfer receivable or payable for each state by comparing its estimated risk score to the state average risk score. The Company records a receivable or payable as an adjustment to its premium revenues to reflect the year-to-date impact of the risk adjustment based on its best estimate. The Company reevaluates its risk adjustment transfer estimates as new information and market data becomes available until final reporting is received from CMS in later periods, which may be up to twelve months in arrears.

The following table provides a rollforward of the Company’s beginning and ending risk adjustment receivable and payable balances for the nine months ended September 30, 2025 and 2024:

In July 2025 the Company received third-party reports, based on industry claims data through April 2025, providing estimates of the market risk score (a measure of market morbidity) for the states where it participates in the ACA. As a result of this new data, the Company significantly increased its estimate of the risk adjustment transfer as of June 30, 2025. The Company further increased its estimate of the risk adjustment transfer as of September 30, 2025 based on the updated estimates of the market risk score received in September 2025 relating to industry claims data through July 2025.

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations

The following discussion and analysis of our financial condition and results of operations should be read in conjunction with the unaudited Condensed Consolidated Financial Statements and the related notes thereto included elsewhere in this Quarterly Report on Form 10-Q and the audited Consolidated Financial Statements and notes thereto and Management's Discussion and Analysis of Financial Condition and Results of Operations (“MD&A”) included in our Annual Report on Form 10-K for the year ended December 31, 2024 that was filed with the SEC on February 20, 2025. Unless the context otherwise requires, references in this MD&A to “we,” “us,” “our,” “Oscar,” “Oscar Health, Inc,” and the “Company” mean the business and operations of Oscar Health, Inc. and its consolidated subsidiaries.

Overview

Oscar is a leading healthcare technology company built around a full stack technology platform and a relentless focus on member experience. We have been challenging the status quo in the healthcare system since our founding in 2012, and are dedicated to making a healthier life accessible and affordable for all. Oscar serves individuals, families, and employees through the Patient Protection and Affordable Care Act (“ACA”). We also offer health technology solutions that power the healthcare industry through +Oscar. In May 2025, the Company purchased 100% of the equity interests in three businesses operating in the individual market: INSXCloud, Inc. (an approved enhanced direct enrollment platform), IHC Specialty Benefits, Inc. (an insurance agency that sells individual medical and supplemental health products), and Healthinsurance.org, LLC (an online resource providing educational content for consumers navigating health insurance and the ACA marketplace). Our technology drives superior experiences, deep engagement, and high-value clinical care, earning us the trust of approximately 2.1 million effectuated members (“members”) as of September 30, 2025. Effectuated members are those who are actively enrolled in one of the Company’s plans and whose required premium payments have either been made or are within the payment grace period.

We regularly review our Total revenue, Medical loss ratio (“MLR”), Selling, general, and administrative expense ratio (“SG&A expense ratio”), Earnings from operations, and Net income (loss) attributable to Oscar Health, Inc. to evaluate our business, measure our performance, identify trends in our business, prepare financial projections, and make strategic decisions. We believe these operational and financial measures are useful in evaluating our performance, in addition to our financial results prepared in accordance with GAAP.

Total Revenue

Total revenue includes Premium revenue (net of risk adjustment transfers), Investment income, and Other revenues. We believe Total revenue is an important metric to assess the growth of our business, as well as the earnings potential of our investment portfolio.

Table of Contents

MLR

MLR is a metric used to calculate medical expenses as a percentage of net premiums before ceded quota share reinsurance. The impact of the federal risk adjustment program is included in the denominator of our MLR. We believe MLR is an important metric to demonstrate the ratio of our costs to pay for the healthcare of our members to the net premium before ceded quota share reinsurance. MLRs in our products are subject to various federal and state minimum requirements.

SG&A Expense Ratio

The SG&A expense ratio reflects the Company’s selling, general, and administrative expenses, as a percentage of Total revenue (net of risk adjustment transfers). We believe the SG&A expense ratio is useful to evaluate our ability to manage our overall selling, general, and administrative cost base.

Earnings (Loss) from Operations

Earnings (loss) from operations is the Company's Total revenue less Total operating expenses. We believe Earnings (loss) from operations is an important primary metric for assessing operating performance.

Net Income (Loss) Attributable to Oscar Health, Inc.

Net income (loss) attributable to Oscar Health, Inc. is Net earnings (loss) allocated to the Company after net income (loss) attributable to noncontrolling interests. It is a key indicator of the Company’s profitability and operational efficiency, allowing management to evaluate performance and make informed decisions on strategic planning, cost management, and resource allocation.

Recent Developments, Trends and Other Key Factors Impacting Performance

Regulatory Developments and Trends

Our operations are subject to comprehensive and detailed federal, state, and local laws and regulations, which continue to rapidly evolve and change. Developments related to the regulatory regimes under which we operate have in the past impacted, and are expected to continue to impact, our results of operations. The following regulatory developments have impacted our operations during the periods presented in the financial statements contained elsewhere in this Quarterly Report on Form 10-Q, or are expected to impact our results of operations in future periods.

The ACA

The ACA established significant subsidies to support the purchase of health insurance by individuals, in the form of advanced premium tax credits (“APTCs”), available through Health Insurance Marketplaces. The American Rescue Plan Act (“ARPA”) increased the size of APTCs for 2021 and 2022, and the Inflation Reduction Act of 2022 renewed the enhanced APTCs for three years through the end of 2025. If Congress does not take action, the enhanced APTCs will expire at the end of 2025. If the enhanced APTCs are not renewed, insurance coverage could become unaffordable for certain individuals.

The Centers for Medicare & Medicaid Services (“CMS”) is increasingly focused on improving integrity in the Health Insurance Marketplace eligibility and enrollment process, and we expect this focus to continue. During the second half of 2024, CMS enacted new measures to respond to increases in unauthorized changes in consumer enrollments by agents and brokers and to reduce consumer burdens related to unauthorized enrollments. While these measures are important to prevent unauthorized enrollments, they may also make it more difficult for individuals to complete valid enrollments in new plans, switch from one plan to another, or obtain APTCs. In addition, on June 25, 2025, CMS issued a rule that created stricter eligibility verification processes for APTCs, as well as other requirements related to ACA plan enrollment, including shorter open enrollment periods and the suspension of certain special enrollment periods (the “Program Integrity Rules”). On August 22, 2025, in connection with City of Columbus vs. Kennedy, in which the plaintiffs alleged certain provisions of the Program Integrity Rules are contrary to law, a federal district court in Maryland issued a nationwide stay on several provisions of the Program Integrity Rules pending a final ruling on the merits of the case. We do not expect that the litigation will conclude before 2026 and CMS has confirmed that the stayed provisions will not be in effect during the 2026 open enrollment period. Many of the stayed provisions would have otherwise impacted enrollment processes and APTC eligibility during the 2026 open enrollment period. For example, the court stayed the application of a $5 monthly premium to enrollees in $0 premium

plans who do not actively reenroll during open enrollment. Provisions of the Program Integrity Rules unaffected by the stay became effective on August 25, 2025. Furthermore, on July 4, 2025, the President signed into law the One Big Beautiful Bill Act (the “OBBBA”) which, among other relevant matters, limits the eligibility of APTCs for certain populations, and requires additional verification procedures to confirm member eligibility for APTCs.

The implementation of the Program Integrity Rules, the OBBBA, and the discontinuation of the enhanced APTCs (if not renewed at the end of 2025), will likely reduce overall participation in the Health Insurance Marketplaces, and any resulting market contraction could negatively impact market morbidity. Furthermore, if the enhanced APTCs are extended before the end of the year, there could be operational and financial impacts to Oscar. For additional details on how these factors may impact Oscar, see “Risk Factors-Most Material Risks to Us-Our success and ability to grow our business depend in part on retaining and expanding our member base. If we fail to add new members or retain current members, or manage our membership growth appropriately to meet our business objectives, our business, revenue, operating results, and financial condition could be harmed” and “Risk Factors–Most Material Risks to Us–Failure to accurately estimate our incurred medical expenses or effectively manage our medical costs or related administrative costs could negatively affect our financial position, results of operations, and cash flows” in this Quarterly Report on Form 10-Q and “Risk Factors–Most Material Risks to Us–Any changes to the ACA and its regulations could materially and adversely affect our business, results of operations, and financial condition” and “Business–Government Regulation–Ongoing Requirements and Changes to the ACA” in our Annual Report on Form 10-K for the year ended December 31, 2024.

Medicaid redeterminations began on April 1, 2023 and CMS announced a Special Enrollment Period (“SEP”) that began March 31, 2023 and ended November 30, 2024 to facilitate enrollment in the ACA by individuals who lost Medicaid coverage under the redetermination process. While CMS announced in 2024 that all unwinding-related renewals for beneficiaries enrolled in Medicaid or the Children's Health Insurance Program (“CHIP”) must be completed no later than December 31, 2025, our understanding is that the majority of states substantially completed their unwinding processes in 2024. We believe these Medicaid redeterminations have previously contributed to increases in our membership, however, we anticipate that any future impact on our membership will not be as significant as the membership growth we previously experienced. We believe that members who have enrolled in the ACA through the Medicaid redetermination process are higher utilizers of care and have increased the overall morbidity of the Health Insurance Marketplace. For additional details, see “Risk Factors–Most Material Risks to Us–Failure to accurately estimate our incurred medical expenses or effectively manage our medical costs or related administrative costs could negatively affect our financial position, results of operations, and cash flows” in this Quarterly Report on Form 10-Q and “Business–Government Regulation–Ongoing Requirements and Changes to the ACA” in our Annual Report on Form 10-K for the year ended December 31, 2024.

Proposed Tariffs

The Trump administration has indicated that new tariffs may be imposed on a variety of products relevant to our business, including certain pharmaceutical products and ingredients and medical devices and supplies imported into the United States. If such tariffs are imposed, the potential impact could include, among other things, higher costs for medical providers and facilities, higher pharmaceutical prices, higher costs of medical devices, and supplies and shortages of certain medicines and medical supplies. Shortages in medicines and supplies may also impact the health of our members, which in turn may result in higher medical costs. The unprecedented nature of these types of tariffs, as well as uncertainty around their implementation, could impact our ability to accurately estimate and effectively manage the impact on our medical expenses, which in turn could adversely affect our results of operations and financial position. For additional details, see “Risk Factors-Most Material Risks to Us-Failure to accurately estimate our incurred medical expenses or effectively manage our medical costs or related administrative costs could negatively affect our financial position, results of operations, and cash flows” in this Quarterly Report on Form 10-Q.

Members

Our membership is measured as of a particular point in time. Membership may change due to the pricing of, and benefits offered under, our plans both relative to our competitors and considered on a stand-alone basis, our expansion into or exiting of certain markets, and may vary throughout the year due to disenrollments, SEP, and other market dynamics that are in effect such as Medicaid redeterminations, enhancements, extensions, reductions or eliminations of APTCs, other legislative or regulatory actions, such as recent CMS initiatives to improve the integrity in the ACA eligibility and enrollment process, pre-enrollment verification procedures required by OBBBA, or other factors that cause the overall market to grow or decline.

Risk Adjustment

The risk adjustment programs in the markets we serve are administered federally by CMS and are designed to mitigate the potential impact of adverse selection and provide stability for health insurers. Under this program, each plan is assigned a risk score based upon demographic information and current year claims information related to its members. The risk score is used to adjust plan revenue to reflect the relative risk of the plan's enrolled population. We reevaluate our risk adjustment transfer estimates as new information and market data becomes available, until we receive the final reporting from CMS in later periods, up to twelve months in arrears. In July 2025, the Company received third-party reports, based on industry claims data through April 2025, providing estimates of the market risk score (a measure of market morbidity) for the states where it participates in the ACA. As a result of this new data, the Company significantly increased its estimate of the risk adjustment transfer as of June 30, 2025. The Company further increased its estimate of the risk adjustment transfer as of September 30, 2025 based on the updated estimates of the market risk score received in September 2025 relating to industry claims data through July 2025.

Our risk transfer estimates are subject to a high degree of estimation and variability, and are affected by the relative risk of our members, and in the case of ACA, that of other insurers. The data that we rely upon to calculate these estimates includes data received from independent third parties. In addition, the data may be incomplete, can vary considerably from period to period, requires considerable judgment in interpretation, lacks context, and provides limited insight. Moreover, our risk transfer estimates are subject to change due to factors outside of our control, such as changes in legislation, regulations, regulatory enforcement, enrollment in government health plans, inflation, market size, market morbidity, the actions of our competitors, and other uncertainties. There is a higher degree of uncertainty associated with estimates of risk adjustment transfers earlier in the policy year or, in the case of SEP driven enrollment, throughout the policy year, resulting from the fact that risk scores are based on lagged claim data. There is additional uncertainty for both markets and blocks of business that experience outsized growth, compounded by the lack of credible experience data on the newly enrolling population, including SEP driven enrollees and new members moving from one government program to another. Furthermore, there is also uncertainty associated with changes in other carriers operations, which may impact the ultimate degree of market-level risk. Actual risk adjustment calculations and transfers have in the past materially differed, and could materially differ in the future, from our assumptions.

Claims Incurred

Our medical expenses are impacted by unit costs and utilization, as well as seasonal effects on medical costs, such as the utilization of deductibles and out-of-pocket maximums over the course of the policy year, which shift more costs to us in the second half of the year as we pay a higher proportion of covered claims costs, and the number of days and holidays in a given period. Our medical and pharmacy costs can also exhibit seasonality depending on selection effects or changes in the risk profile of our membership and the proportion of our membership that is new in the calendar year. The emergence of medical and pharmacy claims is influenced by the aforementioned drivers, and further mix shifts may continue to alter claims incurred patterns in future periods.

Seasonality

Our business is generally affected by the seasonal patterns of our member enrollment, medical expenses, and health plan mix shift and product design. SEP or other market dynamics that drive enrollment and/or mix changes throughout the year may impact the per member levels of premiums, claims, and/or risk adjustment transfers.

SEP Market Dynamics Developments and Trends

During the year ended December 31, 2024, the increase in our membership was due in part to an increase in member enrollments through SEP which impacted our MLR. Higher SEP growth in certain markets throughout 2024 may have contributed to the increase in our risk transfer payable for the year ended December 31, 2024 and the nine months ended September 30, 2025. SEP enrollment volumes across the ACA market in 2025 are largely back to historical baselines as are the associated MLR risks that those enrollments introduce.

Reinsurance

We believe our reinsurance agreements help us achieve important goals for our business, including risk management and capital efficiency. Our reinsurance agreements are contracted under two different types of arrangements: quota share reinsurance contracts and excess of loss (“XOL”) reinsurance contracts. In quota share reinsurance, the reinsurer agrees to assume a specified percentage of the ceding company’s losses in exchange for a corresponding percentage of premiums. In XOL reinsurance, the reinsurer agrees to assume all or a portion of the ceding company’s losses in excess of a specified amount. Under XOL reinsurance, the premium payable to the reinsurer is negotiated by the parties based on losses on an individual member in a given calendar year and their assessment of the amount of risk being ceded to the reinsurer. In the case of federal and state-run reinsurance programs, no reinsurance premiums are paid. The reinsurance agreements do not relieve us of our primary medical claims incurred obligations. Refer to “Note 9 - Reinsurance” included elsewhere in this Quarterly Report on Form 10-Q for a description of the accounting methods used to record our quota share reinsurance arrangements.

Critical Accounting Policies and Estimates

The preparation of financial statements in accordance with generally accepted accounting principles requires management to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses. A summary of the Company's significant accounting policies is included in “Note 2 - Summary of Significant Accounting Policies,” in our Annual Report on Form 10-K for the year ended December 31, 2024. Certain of our accounting policies are considered critical, as these policies require significant, difficult or complex judgments by management, often requiring the use of estimates about the effects of matters that are inherently uncertain. As of September 30, 2025, there were no significant changes to our critical accounting estimates from what was reported in our Annual Report on Form 10-K for the year ended December 31, 2024.

Components of Our Results of Operations

Premium

Premium revenue includes direct policy premiums collected from our members and subsidies received from the federal government, net of risk adjustment transfers, and assumed policy premiums we earned as part of our reinsurance arrangement under our former Cigna+Oscar Small Group plan offering, and is net of ceded premium from XOL and run-off quota share reinsurance contracts accounted for under reinsurance accounting. The Company did not renew the Cigna+Oscar Small Group arrangement after the expiration of the initial term on December 31, 2024.

Investment Income

Investment income primarily includes investment income, interest earned, and gains (losses) on our investment portfolio.

Other Revenues

Table of Contents

Medical

Medical expense primarily consists of both paid and unpaid medical expenses incurred to provide medical services and products to our members. Medical claims include fee-for-service claims, pharmacy benefits, capitation payments to providers, disputed provider claims, and various other medical-related costs. Under fee-for-service claims arrangements with providers, we retain the financial responsibility for medical care provided and incur costs based on actual utilization of hospital and physician services. Medical claims are recognized in the period healthcare services are provided. Unpaid medical expenses include claims reported and in the process of being settled, but that have not yet been paid, as well as healthcare costs incurred but not yet reported to us, which are collectively referred to as benefits payable or claim reserves. The development of the claim reserve estimate is based on actuarial methodologies that consider underlying claim payment patterns, medical cost inflation, historical developments, such as claim inventory levels and claim receipt patterns, and other relevant factors. The methods for making such estimates and for establishing the resulting liability are continuously reviewed and any adjustments are reflected in the period determined. Medical expense also reflects the net impact of our ceded reinsurance claims from XOL and run-off quota share reinsurance contracts accounted for under reinsurance accounting.

Selling, General, and Administrative Expenses

Selling, general, and administrative expenses primarily include distribution and servicing costs, premium taxes, exchange fees, other taxes and fees, employee-related expenses, costs of software and hardware, stock-based compensation, the impact of quota share reinsurance, and other administrative costs.

Other Expenses (Income)

Other expenses (income) consists primarily of miscellaneous expenses or income that are not core to our operations, including profit sharing arrangements with our co-branded health plans and changes in the fair value of financial instruments.

Income Tax Expense (Benefit)

Income tax expense (benefit) consists primarily of changes to our current and deferred federal and state tax assets and liabilities. Income taxes are recorded as deferred tax assets and deferred tax liabilities based on differences between the book and tax bases of assets and liabilities. Our deferred tax assets and liabilities are calculated by applying the current tax rates and laws to taxable years in which such differences are expected to reverse.

Net income (loss) Attributable to Noncontrolling Interests

Net income (loss) attributable to noncontrolling interests represents the share of the Company’s earnings allocated to the Company’s joint venture partner.

Premium

Premium revenue increased $555.7 million or 23% for the three months ended September 30, 2025, compared to the same period in 2024, and increased $2,097.2 million, or 32%, for the nine months ended September 30, 2025, compared to the same period in 2024. This increase was driven by higher membership, partially offset by an increase in the net risk adjustment transfer accrual. As of September 2025, membership increased by 0.5 million, or 28%, compared to September 2024, primarily driven by above market growth during the 2025 Open Enrollment period.

The following table summarizes the Company’s membership by offering:


	As of September 30,
Membership by Offering	2025	2024
Individual and Small Group	2,111,736	1,602,993

Cigna+Oscar (1)	5,168	51,291
Total Members (2)	2,116,904	1,654,284

(1) Represents total membership for our former co-branded partnership with Cigna.
(2) Represents effectuated members. Effectuated members are those who are actively enrolled in one of our plans and whose required premium payments have either been made or are within the payment grace period. A member covered under more than one of our health plans counts as a single member for the purposes of this metric.

Investment Income

Investment income increased $2.9 million or 6% for the three months ended September 30, 2025, compared to the same period in 2024, and increased $10.0 million, or 7%, for the nine months ended September 30, 2025, compared to the same period in 2024, primarily due to a larger asset base, partially offset by lower yield.

Medical Expenses and MLR

Medical expenses increased $582.4 million, or 29% for the three months ended September 30, 2025, compared to the same period in 2024, and increased $2,131.5 million, or 40%, for the nine months ended September 30, 2025, compared to the same period in 2024. This increase was primarily due to increased membership and medical cost trend.

MLR increased for the three months and nine months ended September 30, 2025, compared to the same periods in 2024, primarily driven by an increase in average market morbidity that resulted in an increase in the net risk adjustment transfer accrual, partially offset by favorable prior period development.

Selling, General, and Administrative Expenses and SG&A Expense Ratio

Selling, general, and administrative expenses increased $61.2 million or 13% for the three months ended September 30, 2025, compared to the same period in 2024, and increased $249.1 million, or 19%, for the nine months ended September 30, 2025, compared to the same period in 2024. This increase was primarily driven by higher membership year over year, resulting in higher volume-driven costs such as broker commissions and taxes and fees, partially offset by lower unit cost economics.

The SG&A expense ratio decreased 153 basis points to 17.5% for the three months ended September 30, 2025, compared to 19.0% for the same period in 2024. The SG&A expense ratio also decreased 170 basis points to 17.3% for the nine months ended September 30, 2025, compared to 19.0% for the same period in 2024. The decrease was primarily due to greater fixed cost leverage, lower exchange fee rates, and disciplined cost management, partially offset by the impact of higher risk adjustment as a percentage of premium.

Liquidity and Capital Resources

Overview

We maintain liquidity at two levels of our corporate structure, through our health insurance subsidiaries (any subsidiary of Oscar Health, Inc. that has applied for or received a license, certification or authorization to sell health plans by any state Department of Insurance, Department of Financial Services, Department of Health, or comparable regulatory authority) and through our holding company (our parent company, Oscar Health, Inc., on a standalone basis (“Parent”) and subsidiaries excluding our health insurance subsidiaries).

The majority of the assets held by the holding company are in the form of cash and cash equivalents and investments. As of September 30, 2025 and December 31, 2024, total cash and cash equivalents and investments held by the holding company were $540.9 million and $189.8 million, respectively, of which $9.7 million and $12.8 million was restricted as of September 30, 2025 and December 31, 2024, respectively.

The majority of the assets held by our health insurance subsidiaries are in the form of cash and cash equivalents and investments. As of September 30, 2025 and December 31, 2024, total cash and cash equivalents and investments held by our health insurance subsidiaries were $4.3 billion and $3.8 billion, respectively, of which $18.2 million and $18.0 million, respectively, was on deposit with regulators as required for statutory licensing purposes. These amounts are classified as restricted deposits on the balance sheets.

Our health insurance subsidiaries’ states of domicile have statutory minimum capital requirements that are intended to measure capital adequacy, taking into account the risk characteristics of an insurer’s investments and products. The combined statutory capital and surplus of our health insurance subsidiaries was estimated to be approximately $1.3 billion and $1.2 billion as of September 30, 2025 and December 31, 2024, respectively, which was in compliance with and in excess of the minimum capital requirements for each period. The health insurance subsidiaries historically have required capital contributions from Parent to maintain minimum levels. The health insurance subsidiaries in aggregate exceeded the minimum statutory RBC requirement by approximately $734 million as of December 31, 2024 and are estimated to have approximately $564.1 million of excess capital as of September 30, 2025. The health insurance subsidiaries may be subject to additional capital and surplus requirements in the future, as a result of factors such as increasing membership and medical costs or changes in risk adjustment transfer estimates, which may require us to incur additional indebtedness, sell capital stock, or access other sources of funding in order to fund such requirements. During periods of increased volatility, adverse securities and credit markets, including those due to rising interest rates, may exert downward pressure on the availability of liquidity and credit capacity for certain issuers, and any such funding may not be available on favorable terms, or at all.

Table of Contents

As certain of our health insurance subsidiaries have become profitable and to the extent their levels of statutory capital and surplus exceed minimum regulatory requirements, we may make periodic requests for dividends and distributions from our subsidiaries to fund our operations or seek to enter into transactions or structures that enable us to efficiently deploy this excess capital, which may or may not require approval by our regulators. During the nine months ended September 30, 2025, our health insurance subsidiaries made loan repayments of $15.0 million. During the nine months ended September 30, 2024, our health insurance subsidiaries issued dividends and made loan repayments of $133.0 million to Parent.

During the nine months ended September 30, 2025 and September 30, 2024, respectively, Parent made $65.8 million and $99.8 million of capital contributions to the health insurance subsidiaries. Our health insurance subsidiaries also utilize quota share reinsurance arrangements to reduce our minimum capital and surplus requirements, which are designed to enable us to efficiently deploy capital to fund our growth. We estimate that had we not had any quota share reinsurance arrangements in place, the health insurance subsidiaries would have been required to hold approximately $671.8 million and $553.8 million of additional capital as of September 30, 2025 and December 31, 2024, respectively, which the Parent would have been required to fund to the extent the applicable insurance subsidiary did not have excess capital to cover the requirement.

Short-Term Cash Requirements

The Company’s cash requirements within the next twelve months include benefits payable, risk adjustment transfer payables, current lease liabilities, interest payable on debt, other current liabilities and purchase commitments and other obligations. We expect the cash required to meet these obligations to be primarily funded by cash available for general corporate use, cash flows from current operations, and/or the realization of current assets, such as accounts receivable. Based on our current forecast, we believe the Company's cash, cash equivalents, and investments, not including restricted cash, will be sufficient to fund our operating requirements for at least the next twelve months.

Long-Term Cash Requirements

Our long-term cash requirements under our various contractual obligations and commitments include operating leases. We expect the cash required to meet our long-term obligations to be primarily generated through future cash flows from operations. See “Note 13 - Leases” in our Annual Report on Form 10-K for the year ended December 31, 2024 for further detail of our obligations and the timing of expected future payments.

Convertible Senior Notes

On February 3, 2022, we issued $305.0 million in aggregate principal amount of convertible senior notes due 2031 (the “2031 Notes”) in a private placement to funds affiliated with or advised by Dragoneer Investment Group, LLC, Thrive Capital, LionTree Investment Management, LLC, and Tenere Capital LLC (the “Initial Purchasers”). In connection with the sale and issuance of the 2031 Notes, on January 27, 2022, we entered into an investment agreement with the Initial Purchasers (the “Investment Agreement”) and on February 3, 2022, we entered into an indenture with U.S. Bank, as Trustee (the “2031 Indenture”). On September 11, 2025, we entered into an amendment to the Investment Agreement. The purpose of the Amendment was to permit the private offering of the 2030 Notes (as defined below) under the Investment Agreement.

The 2031 Notes bear interest at a rate of 7.25% per annum, payable in cash, semi-annually in arrears on June 30 and December 31 of each year, commencing on June 30, 2022. The 2031 Notes will mature on December 31, 2031, subject to earlier repurchase, redemption, or conversion.

The holders of the 2031 Notes may require us to repurchase the 2031 Notes for cash, upon a fundamental change (as defined in the 2031 Indenture) or on June 30, 2027 and each anniversary thereof until June 30, 2030. In addition, we may redeem the 2031 Notes on or after December 31, 2026 if certain Class A common stock sales price and other conditions are satisfied.

The 2031 Notes may be converted at the election of the holders under certain circumstances, including if we call the 2031 Notes for redemption or upon satisfaction of a Class A common stock sale price condition. During the quarterly period ended September 30, 2025, the Class A common stock sale price condition was satisfied. As a result, the 2031 Notes are convertible during the fourth quarter of 2025 at the option of the holder. Upon conversion, we may elect to settle the 2031 Notes in shares of Class A common stock, cash, or a combination of both, unless an Initial Purchaser of the 2031 Notes elects to receive the consideration due upon conversion solely in shares of Class A common stock pursuant to the terms of the Investment Agreement.

For more information on our 2031 Notes, including details relating to repurchase, redemption and conversions of the 2031 Notes, see “Part II, Item 7 Management’s Discussion and Analysis of Financial Condition and Results of Operations—Liquidity and Capital Resources—Convertible Senior Notes” and “Note 9 - Debt” to our Consolidated Financial Statements, each in our Annual Report on Form 10-K for the year ended December 31, 2024, and, “Note 8 – Debt” to our Condensed Consolidated Financial Statements included elsewhere in this Quarterly Report on Form 10-Q.

Convertible Senior Subordinated Notes

The 2030 Notes will accrue interest at a rate of 2.25% per annum, payable semi-annually in arrears on March 1 and September 1 of each year, beginning on March 1, 2026. The 2030 Notes will mature on September 1, 2030, unless they are earlier repurchased, redeemed, or converted.

The holders of the 2030 Notes may require us to repurchase the 2030 Notes for cash, upon a fundamental change (as defined in the 2030 Indenture), subject to certain conditions. In addition, we may redeem the 2030 Notes on or after September 6, 2028, if certain Class A common stock sales price and other conditions are satisfied.

On September 15, 2025, in connection with the pricing of the offering of 2030 Notes, the Company entered into privately negotiated capped call transactions (the “Base Capped Call Transactions”) with certain of the 2030 Notes initial purchasers or their affiliates and certain other financial institutions (the “Option Counterparties”). In addition, on September 16, 2025, in connection with the initial purchasers’ exercise of their option to purchase additional 2030 Notes, the Company entered into additional capped call transactions (the “Additional Capped Call Transactions,” and, together with the Base Capped Call Transactions, (the “Capped Call Transactions”) with each of the Option Counterparties. The Capped Call Transactions cover the aggregate number of shares of the Company’s Class A common stock that initially underlie the 2030 Notes (subject to customary anti-dilution adjustments), and are expected to reduce potential dilution to the Company’s Class A common stock upon any conversion of 2030 Notes and/or offset any cash payments the Company is required to make in excess of the principal amount of converted 2030 Notes, with such reduction and/or offset subject to a cap, based on the cap price of the Capped Call Transactions.

Revolving Credit Facility

On December 28, 2023, we entered into a third amendment to our senior secured credit agreement with Wells Fargo Bank, National Association, as lender and administrative agent, and certain other lenders party thereto from time to time (collectively, the “Lenders”), and Oscar Management Corporation, as a subsidiary guarantor, which amended the senior secured credit agreement, dated as of February 21, 2021 (as previously amended by the First Amendment to Credit Agreement, dated as of January 27, 2022 and the Second Amendment to Credit Agreement, dated as of July 21, 2023, the “Amended Credit Agreement”). The Amended Credit Agreement provided for a revolving loan credit facility (the “Revolving Credit Facility”) in the aggregate principal amount of $115.0 million, with proceeds to be used for general corporate purposes of the Company. On September 18, 2025, we terminated the Revolving Credit Facility. At the time of termination, there were no outstanding borrowings under the Revolving Credit Facility.

Investments

We generally invest our cash in U.S. Treasury instruments, federal and state agency securities, investment grade corporate bonds, and asset backed securities to improve our overall investment return. These investments are purchased pursuant to board-approved investment policies that reflect our obligations under our credit agreement and conform to applicable state laws and regulations.

Our investment policies are designed to provide liquidity, preserve capital, and optimize the total return on invested assets. These policies also align with the constraints of state regulations governing the types of investments our health insurance subsidiaries can hold. These investment policies require that our investments in U.S. corporate bonds and asset backed securities have final maturities of no more than five years from the date of issuance and U.S. federal and state government obligations have final maturities of no more than seven years from the settlement date. Professional portfolio managers operating under documented guidelines manage our investments and a portion of our cash equivalents. Our portfolio managers are directed to obtain our prior approval before selling investments in a loss position.

Net investment income on a consolidated basis was $53.2 million and $50.3 million for the three months ended September 30, 2025, and 2024, respectively, and $153.3 million and $143.3 million for the nine months ended September 30, 2025 and 2024, respectively. Net investment income for our health insurance subsidiaries was $50.6 million and $47.8 million for the three months ended September 30, 2025 and September 30, 2024, respectively, and $146.7 million and $135.3 million for the nine months ended September 30, 2025, and September 30, 2024, respectively.

Our restricted investments consist primarily of cash and cash equivalents and U.S. Treasury securities; we have the ability to hold such restricted investments until maturity. The Company maintains cash and cash equivalents and investments on deposit or pledged to various state agencies as a condition for licensure. We classify our restricted deposits as long-term given the requirement to maintain such assets on deposit with regulators.

Summary of Cash Flows

Our cash flows used in operations may differ substantially from our net income due to non-cash charges or due to changes in balance sheet accounts.

The timing of our cash flows from operating activities can also vary among periods due to the timing of payments made or received. Some of our payments and receipts, including loss settlements, rebates from our pharmacy benefit manager, risk adjustment transfers, and subsequent reinsurance receipts, can be significant. Therefore, their timing can influence cash flows from operating activities in any given period. The potential for a large claim under an insurance or reinsurance contract means that our health insurance subsidiaries may need to make substantial payments within relatively short periods of time, which would have a negative impact on our operating cash flows.

Table of Contents

Our primary operating cash flow sources are premiums and investment income. Our primary operating cash flow uses are payments for claims, risk adjustment transfers, and operating expenses, including interest expense. For the nine months ended September 30, 2025, net cash provided by operating activities was $423.0 million as compared with $631.4 million provided by operating activities for the same period in 2024. The decrease was primarily due to higher claim disbursements, risk adjustment payments, premium taxes, and broker expenses, partially offset by higher premiums.

Cash flows from investing activities primarily include the purchase and disposition of financial instruments. For the nine months ended September 30, 2025, net cash used in investing activities was $192.4 million as compared to net cash used in investing activities of $1,356.0 million for the same period in 2024. The change was primarily due to a reduction in the purchases of securities, partially offset by a lower level of maturing investment.

Cash flows from financing activities may include proceeds from the issuance of debt securities, proceeds from stock option exercises, and tax payments related to the net settlement of share-based awards. For the nine months ended September 30, 2025, net cash provided by financing activities was $391.0 million as compared to $64.6 million for the same period in 2024. The increase was due to proceeds from newly issued convertible notes.

Item 3. Quantitative and Qualitative Disclosures about Market Risk

Market risk represents the risk of loss that may impact our financial position due to adverse changes in financial market prices and rates. Our market risk exposure is primarily attributable to potential changes in interest rates and/or inflation and the resulting impact on investment income. We do not hold financial instruments for trading purposes.

Interest Rate Risk

We are subject to interest rate risk in connection with the fair value of our investment portfolio, which consists of U.S. Treasury and agency securities, corporate notes, and certificates of deposit. Our primary market risk exposure is driven by changes to Federal fund effective rates. Interest rate risk is highly sensitive due to many factors, including U.S. monetary and tax policies, U.S. and international economic factors, and other factors beyond our control. Assuming a hypothetical and immediate 1% increase in interest rates on September 30, 2025, the fair value of our investments would decrease by approximately $43.6 million. Any declines in interest rates over time would reduce our investment income.

Item 4. Controls and Procedures

Evaluation of Disclosure Controls and Procedures

Disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) of the Exchange Act) are designed to ensure that information required to be disclosed by us in reports filed or submitted under the Exchange Act is recorded, processed, summarized, and reported within the time periods specified in SEC rules and forms and that such information is accumulated and communicated to management, including the Chief Executive Officer and Chief Financial Officer, as appropriate to allow timely decisions regarding required disclosures. Management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving their objectives.

Our management, with the participation of our Chief Executive Officer and Chief Financial Officer, evaluated, as of the end of the period covered by this report, the effectiveness of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act). Based on that evaluation, our Chief Executive Officer and Chief Financial Officer concluded that, as of September 30, 2025, our disclosure controls and procedures were effective at the reasonable assurance level.

Changes in Internal Control over Financial Reporting

There were no changes in our internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) during the quarter ended September 30, 2025 that materially affected, or are reasonably likely to materially affect, the Company's internal control over financial reporting.

PART II — OTHER INFORMATION

Item 1. Legal Proceedings

The information required under this Part II, Item 1 is set forth in “Note 12 - Commitments and Contingencies” to the Condensed Consolidated Financial Statements included elsewhere in this Quarterly Report on Form 10-Q.

Given that such proceedings are subject to uncertainty, there can be no assurance that such legal proceedings, either individually or in the aggregate, will not have a material adverse effect on our business, results of operations, financial condition or cash flows.

Item 1A. Risk Factors

Except as set forth in the amended and restated risk factors below, there have been no material changes to the risk factors disclosed in Part I, Item 1A, of our Annual Report on Form 10-K for the year ended December 31, 2024.

Our success and ability to grow our business depend in part on retaining and expanding our member base. If we fail to add new members or retain current members, or manage our membership growth appropriately to meet our business objectives, our business, revenue, operating results, and financial condition could be harmed.

We currently derive substantially all of our revenue from direct policy premiums, which are primarily driven by the number of members covered by our health plans. As a result, the size of our member base is critical to our success. We have experienced significant member growth since we commenced operations; however, we may not be able to maintain this growth or manage our membership growth appropriately to meet our business objectives, and our member base could decrease rapidly or shrink over time.

There are many factors that could negatively affect our ability to retain existing members and expand our member base, many of which are beyond our direct control, including if:

•we are unable to remain competitive on member experience, pricing, and insurance coverage options;

•we are unable to gain access to quality providers;

•we are unable to develop or maintain competitive provider networks, or maintain adequate networks that comply with regulatory requirements and standards;

•insurance brokers that we rely on to build our member base are unable to market our insurance products effectively;

•we fail to attract brokers to sell our insurance products or lose important broker relationships to our competitors or otherwise, including in circumstances where we require brokers to use different enrollment services vendors;

•the enhanced advanced premium tax credits “APTCs” under the American Rescue Plan Act “ARPA” are not renewed after 2025, or are otherwise eliminated or reduced, or other APTCs or subsidies under the ACA are eliminated or reduced;

•the enhanced APTCs are renewed, in whole or in part, late in 2025;

•regulatory or legislative actions to improve the integrity in the ACA eligibility and enrollment process, such as the CMS Program Integrity Rules and the OBBA, impact membership, including as a result of periodic data matching operations and rules that make it more difficult for members to enroll in new plans, switch from one plan to another, or obtain APTCs;

•we increase pricing as a result of changes or developments in the Health Insurance Marketplaces, including as a result of increased morbidity in the market;

•our competitors or new market entrants successfully mimic our innovative product offerings or our full stack technology platform;

•we are unable to maintain licenses and approvals, or there are material modifications or restrictions on our ability to offer insurance in our current markets or to participate on Health Insurance Marketplaces, obtain licenses and approvals to offer insurance in new markets, or to otherwise expand our plan offerings in an economically sustainable manner;

•we fail to continue to offer differentiated and competitive products, or there are regulatory actions that limit the types of plans that can be offered, such as the Notice of Benefit and Payment Parameters;

•initiatives designed to improve member and provider experience, including the use of AI technologies or other new technologies, are unsuccessful or discontinued, whether as a result of actions by us, our competitors, regulators, or other third parties;

Table of Contents

•as a result of changes in law or otherwise, our competitors participate in the individual market to a greater extent than they have previously;

•there is an initiation of a new Special Enrollment Period (“SEP”), termination of an existing SEP, or other unexpected healthcare market developments, including in response to legislative, regulatory or political developments and executive orders;

•our digital platform experiences technical or other problems or disruptions that frustrate the experience of members or providers or other third-party partners;

•we or our partners or other third parties with whom we collaborate sustain a cyber-attack or suffer privacy or data security breaches;

•we experience unfavorable shifts in perception of our digital platform or other member service channels;

•we suffer reputational harm to our brand resulting from negative publicity, whether accurate or inaccurate;

•our strategic partners terminate or fail to renew our current contracts or we fail to enter into contracts with new strategic partners; or

•our efforts to partner with ICHRA platforms to transition small, mid-sized and large employers to the individual market where their employees can choose an Oscar product are not successful, or take significantly more time than expected to be successful.

For example, CMS is increasingly focused on improving integrity in the Health Insurance Marketplace eligibility and enrollment process, and we expect this focus to continue. During the second half of 2024, CMS enacted new measures to respond to increases in unauthorized changes in consumer enrollments by agents and brokers and to reduce consumer burdens related to unauthorized enrollments, and these measures may make it more difficult for members to enroll in new plans or switch from one plan to another. In addition, on June 25, 2025, CMS issued the Program Integrity Rules which, among other things, created stricter eligibility verification processes for APTCs, as well as other requirements related to ACA plan enrollment, including shorter open enrollment periods and the suspension of certain special enrollment periods. For instance, certain provisions that went into effect in August 2025 include a pause in the SEP for individuals making <150% of the Federal Poverty Level (“FPL”). In addition, starting in 2026 with respect to policy year 2027, the rules will change the annual open enrollment period (“OEP”) for all individual market coverage to run from November 1 through December 15 preceding the coverage year, instead of through January 15 of the coverage year. Many of the provisions of the Program Integrity Rules would have impacted enrollment processes and APTC eligibility in the 2026 OEP, except that a federal district court in Maryland stayed certain provisions of the rules in connection with City of Columbus v. Kennedy. The court found that the plaintiffs were likely to succeed on the merits with respect to their claims that certain provisions were contrary to law or arbitrary and capricious and therefore stayed these provisions pending the outcome of the litigation. The stayed provisions included stricter income eligibility verification processes for APTCs, such as provisions requiring more frequent reconciliation of APTC eligibility against tax returns, which would have impacted the number of individuals that qualified for APTCs. In addition, the court stayed the provision imposing a $5 monthly premium on enrollees in $0 premium plans who do not actively reenroll during open enrollment, which would have effectively prevented automatic re-enrollment in the 2026 OEP. We do not expect that this litigation will conclude before 2026, and CMS has confirmed that the stayed provisions will not be in effect during the 2026 OEP.

We expect the Program Integrity Rules could result in a number of individuals in states where we operate losing eligibility for APTCs and could therefore reduce the number of individuals enrolled in the Health Insurance Marketplace. Although we do not expect that the provisions stayed by the court in City of Columbus v. Kennedy will be effective for the 2026 open enrollment period, the provisions that have taken effect, and/or the uncertainty caused by the stayed provisions, may still impact participation during 2026. In addition, we are unable to predict with certainty the outcome of this litigation, or the impact of the Program Integrity Rules on the Health Insurance Marketplace generally or our future membership.

The OBBBA enacted several provisions that may impact the number of Health Insurance Marketplace enrollees and, by extension, the size of our member population. These include ending the APTCs for individuals who enroll in plans via the SEP with income below 150% of the FPL, prohibiting automatic re-enrollment for tax year 2028, and eliminating APTC eligibility for some formerly covered individuals (such as refugees and other immigrant populations). While we expect these provisions to result in a reduction in the number of enrolled individuals in the Health Insurance Marketplace, we cannot predict with certainty the magnitude of the impact on our membership or our business.

The Program Integrity Rules, as well as the OBBBA, could have a material impact on the Health Insurance Marketplace and could also have a material impact on our business, revenue, operating results, and financial condition.

Table of Contents

It is possible that enhanced APTCs could be renewed, but the timing of such a decision, and the manner in which the enhanced APTCs could be renewed, is uncertain and could occur late in 2025, leading to potential disruption and uncertainty for the 2026 open enrollment period. Our failure to effectively anticipate, implement, and manage the operational and regulatory complexities associated with the extension of enhanced APTCs could also result in a negative member experience and make it difficult to manage membership changes effectively, and negatively affect our reputation, financial condition, and results of operations. If the enhanced APTCs are renewed, it is possible that a SEP would be initiated which could alter member mix and enrollment levels (including by allowing individuals who enrolled with us during open enrollment to switch to a competitor’s plan), as well as shift consumer behavior. Because these changes would likely occur with limited advance notice and implementation guidance, we may be required to quickly modify our systems, pricing, enrollment processes, and customer support operations to accommodate new eligibility rules, or marketplace workflows. Accelerated timelines increase the risk of operational errors, system disruptions, and member service issues, including delayed or incorrect premium billing, or data reconciliation challenges with federal and state marketplaces. Additionally, sudden enrollment surges may strain our customer service capacity, technology infrastructure, and third-party vendor relationships, potentially reducing service quality. While we are actively planning for various legislative and regulatory outcomes, including full or partial renewal, and have analyzed several operational pathways to mitigate these risks, these efforts may not be sufficient to prevent adverse impacts on our operations and financial results if the APTCs are renewed in whole or in part by the end of 2025, or are renewed on unfavorable terms.

CMS recently announced the resumption of periodic data matching operations at least twice per calendar year to decrease the number of people simultaneously enrolled in Medicaid/Children's Health Insurance Program “CHIP” and a subsidized ACA health plan. These initiatives include sharing lists of dually-enrolled individuals with states and state-based exchanges, and for those dually enrolled in Medicaid/CHIP and a federally-facilitated exchange plan, directly notifying them so they can rectify their enrollment status. These provisions may result in a reduction in the number of enrolled individuals in the Health Insurance Marketplace, but we cannot predict with certainty the magnitude of the impact on our membership, overall market morbidity, or our business.

We operate in a highly competitive environment and some of the health insurers with which we compete have greater financial and other resources, offer a broader scope of products, and may be able to price their products more competitively than ours. Many of our competitors also have relationships with more providers and provider groups than we do, and can offer a larger network or obtain better unit cost economics. Our inability to overcome these challenges could impair our ability to attract new members and retain existing members, and could have a material adverse effect on our business, revenue, operating results, and financial condition. Additionally, if we are not able to grow our membership, we may be unable to attract additional partners to our +Oscar platform or maintain existing +Oscar partnerships, which could impact our ability to execute our growth strategy.

Failure to accurately estimate our incurred medical expenses or overall market morbidity, or effectively manage our medical costs or related administrative costs could negatively affect our financial position, results of operations, and cash flows.

We set our premiums in advance of each policy year based on competitive factors in each market in which we participate as well as projections of our future expenses and of the future morbidity of the Health Insurance Marketplace. As a result, the profitability of our insurance business depends, to a significant degree, on our ability to accurately estimate and effectively manage our medical expenses and administrative costs, as well as accurately estimate the future morbidity of the Health Insurance Marketplace (and estimate our risk adjustment transfer).

Numerous factors impact our ability to accurately estimate and control our medical expenses, including if the underlying data used as the basis for our estimates is incomplete or doesn’t correctly represent the health of our members. Furthermore, many of these factors are not within our control, including, but not limited to the items set forth below. In addition, many of the factors listed below may also impact our ability to estimate the future morbidity of the Health Insurance Marketplace:

•changes in healthcare regulations and practices, including subregulatory guidance, regulations, or statutes that govern individual plans, or the Health Insurance Marketplaces;

•the impact on the morbidity of our members or the broader market member population from ongoing regulatory actions to improve the integrity in the ACA eligibility and enrollment process (including the Program Integrity Rules and the OBBBA), the potential elimination of enhanced APTCs or the potential extension of enhanced APTCs, in whole or in part, by the end of the year, and Medicaid redeterminations;

Table of Contents

•increases in the costs of healthcare facilities and services, medical devices and supplies, pharmaceutical products and ingredients, including due to the introduction and adoption of new or costly medical technologies and pharmaceuticals, the impact of legislative or regulatory actions, including the imposition of tariffs on certain pharmaceuticals or other foreign imports, or macroeconomic inflationary effects;

•the impact on the morbidity of our members or the broader market member population from any shrinkage in the Health Insurance Marketplace that results from price increases by us or our competitors;

•changes in purchase discounts or pharmacy volume rebates received from drug manufacturers and wholesalers, or the guaranteed minimum discounts or rebates we agree to with the pharmacy benefit manager that negotiates and collects such discounts and rebates on our behalf;

•continued increases in broker fees due to the proportion of broker-acquired business continuing to increase in line with the macro trend in the Health Insurance Marketplace of fewer members signing up directly on exchanges;

•the broader competitive landscape, including new membership resulting from other health insurers exiting our markets or changing their pricing strategies, initiation of new SEPs and general expansion of the individual health insurance market;

•lack of credible data in new regions or with respect to new plan offerings or newly enrolling member populations;

•changes in the utilization of prescription drugs, medical services or other covered items or services, including changes in member utilization patterns ahead of potential lapses in coverage due to regulatory change (such as the potential expiration of the enhanced APTCs);

•changes in our member demographic mix, the geographic concentration of our members, and the distribution of members among our plans;

•increased incidences or acuity of high dollar claims related to catastrophic illnesses or medical conditions, including claims for which we may not have adequate reinsurance coverage;

•changes to, or reductions of, our utilization management functions, such as preauthorization of services, concurrent review or requirements for physician referrals;

•the occurrence of natural disasters, terrorism, public health emergencies, major epidemics and pandemics; and

•provider or broker fraud.

The Consolidated Appropriations Act of 2023 delinked Medicaid redeterminations from the end of the PHE for COVID-19, and Medicaid redeterminations were required to begin by April 1, 2023. Although redeterminations were expected to conclude by June 2024, CMS directed certain states to temporarily pause procedural terminations while they addressed issues in the renewal process that led to increased procedural disenrollments. CMS also announced an SEP that began March 31, 2023 and ended November 30, 2024 to facilitate enrollment in the ACA by individuals who lost Medicaid coverage under the redetermination process. Data from CMS on Medicaid redeterminations showed significant increases in ACA plan enrollments among consumers in 2023 and 2024 who lost Medicaid or CHIP coverage. While CMS announced in 2024 that all unwinding-related renewals for beneficiaries enrolled in Medicaid or CHIP must be completed no later than December 31, 2025, our understanding is that the majority of states had substantially completed their unwinding processes in 2024. We anticipate that any future impact on our membership in connection with ACA enrollments due to the unwinding of the Medicaid continuous enrollment condition will not be as significant as the membership growth we experienced in plan year 2024. We also believe that members who have enrolled in the ACA through the Medicaid redetermination process are higher utilizers of care and have increased the overall morbidity of the Health Insurance Marketplace. However, we cannot predict ACA plan enrollment patterns and the potential impact of recent and future enrollments on market morbidity, and the related impact on our underwriting margin, risk adjustment payables and MLR is therefore uncertain.

Due to the time lag between when services are actually rendered by providers and when we receive, process, and pay a claim for those services, our medical expenses include a provision for claims incurred but not paid. Given the uncertainties inherent in making estimates for such provisions, there can be no assurance that our claims liability estimates will be adequate, and any adjustments to these estimates may unfavorably impact, potentially in a material way, our reported results of operations and financial condition. Further, our inability to estimate our claims liability may also affect our ability to take timely corrective actions, further exacerbating the extent of any adverse effect on our results.

Table of Contents

It is possible that the enhanced APTCs could be renewed, in whole or in part, but the timing of such a decision is uncertain and could occur late in 2025, leading to potential disruption and uncertainty for the 2026 open enrollment period. If enhanced APTCs are renewed, in whole or in part, failure to effectively anticipate, implement, and manage the regulatory and operational complexities could negatively affect our financial condition and results of operations. There are a number of scenarios that regulators could implement, such as requiring plans to refile rates, attempting to reduce premiums on a uniform basis, or requiring us to rebate a portion of our premiums to members or the federal government. Any of these efforts would need to be implemented in a highly compressed timeline, could strain our operational resources and lead to delays, errors, or increased costs, and increase the risk of pricing inaccuracies, margin compression, and/or that premiums are insufficient to cover the cost of our members’ medical expenses. The overall market disruption caused by this uncertainty could also create an unstable operating environment, making it challenging to accurately forecast enrollment and manage our financial outlook. While we are actively planning for various legislative and regulatory outcomes, including full or partial renewal, and have analyzed several operational pathways to mitigate these risks, these efforts may not be sufficient to prevent adverse impacts on our operations and financial results if the enhanced APTCs are renewed in whole or in part before the end of the year or are renewed on unfavorable terms.

We also incur substantial administrative costs, particularly distribution costs, the costs of scaling and improving our operations, and the costs of hiring and retaining personnel. External factors, including general economic conditions such as inflation and unemployment levels and federal and state legislative and regulatory actions, are generally beyond our control and could further reduce our ability to accurately estimate and effectively control our administrative expenses, including the cost of our third-party vendors. Furthermore, regulatory changes or developments may require us to change our existing practices with respect to broker commissions and could potentially result in a substantial increase in related costs or limit our ability to manage those costs in the future. Any such increase in costs could cause our actual results to differ, potentially materially, from our prior expectations. As a result of our market expansion, expansion of our plan offerings and growth of our membership, our anticipated medical expenses and administrative costs are subject to additional uncertainty.

From time to time in the past, our actual results have varied from those expected, particularly in times of significant changes in the number of our members or when we commence or exit operations in a new state or region, and we may experience similar variance in the future. If it is determined that our estimates are significantly different from actual results, our results of operations and financial position could be adversely affected.

The result of risk adjustment programs may impact our revenue, add operational complexity, and introduce additional uncertainties that have a material adverse effect on our results of operations, financial condition, and cash flows.

The individual and small group markets we serve, and the Medicare Advantage markets we formerly served, employ risk adjustment programs that impact the revenue we recognize for our enrolled membership. We reassess the estimates of the risk adjustment settlements each reporting period and any resulting adjustments are made to premium revenue.

As a result of the variability in the mechanics of the program itself, or of certain factors that go into the development of the risk transfers we recognize, such as risk scores, and other market-level factors where applicable, the actual amount of revenue could be materially more or less than our estimates. The data that we rely upon to calculate these estimates includes data received from independent third parties. In addition, the data may be incomplete, can vary considerably from period to period, requires considerable judgment in interpretation, lacks context and provides limited insight. Moreover, our estimates are subject to change due to factors outside of our control, such as changes in legislation, regulations, regulatory enforcement, enrollment in government health plans, inflation, market size, market morbidity, the actions of our competitors, and other uncertainties. Consequently, our estimates of our health plans’ risk scores for any period, our estimates of the risk scores for the markets in which we participate, and any resulting change in our accrual of risk adjustment transfers related thereto, has had a negative impact in the past and could in the future have a material adverse effect on our results of operations, financial condition, and cash flows. For example, in July 2025 we received third-party reports, based on industry claims data through April 2025, providing estimates of the market risk score (a measure of market morbidity) for the states where we participate in the ACA. As a result of this new data, the Company significantly increased its estimate of the risk adjustment transfer as of June 30, 2025. We further increased our estimate of the risk transfer adjustment transfer as of September 30, 2025 based on updated estimates of the market risk score received in September 2025 relating to industry claims data through July 2025. Furthermore, a significant change in our risk adjustment transfer estimates could require us to contribute additional capital to our insurance subsidiaries to meet statutory capital requirements. We may not be able to fund the increased capital contribution requirements with our available cash resources on a timely basis, or at all and may need to incur indebtedness or issue additional capital stock. In the event we need access to capital for such purposes, our ability to obtain such capital may

Table of Contents

be limited and may come at significant cost and could require us to raise capital during periods where additional capital is not available on favorable terms, or at all.

The data provided to CMS to determine our risk scores are subject to audit by CMS for several years after the annual settlements occur. Accordingly, we may continue to be subject to audits related to the Medicare Advantage plans that we historically offered. If the risk adjustment data we submit are found to incorrectly overstate the health risk of our members, we may be required to refund funds previously received by us and/or be subject to penalties or sanctions, including potential liability under the FCA, which could be significant and would reduce our revenue in the year that repayment or settlement is required. Further, if the data we provide to CMS incorrectly understates the health risk of our members, we might be underpaid for the care that we must provide to our members, which could have a negative impact on our results of operations and financial condition.
