Organization, Consolidation and Presentation of Financial Statements [Abstract]  
ORGANIZATION 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 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.

The Company had partnered with Cigna through the Cigna+Oscar partnership to serve the small group employer market. The Company previously offered Medicare Advantage insurance coverage, but exited the Medicare Advantage market for the 2024 plan year.

The Company’s member-first philosophy and innovative approach to care has earned the trust of approximately 1.68 million effectuated members, as of December 31, 2024. Effectuated members are those who are actively enrolled in our plan and have either paid their premium or are within the grace period.

Non-Renewal of Cigna+Oscar Partnership and Exit from the Small Group Market

On March 26, 2024, the Company notified Cigna Health and Life Insurance Company that it would not renew the Cigna+Oscar Small Group arrangement after the expiration of the initial term on December 31, 2024. The parties continued to offer their Cigna+Oscar Small Group product through December 15, 2024. Following termination of the arrangement on December 31, 2024, the Company 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. Additionally, effective December 15, 2024, Oscar no longer offered small group products in any market.

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Accounting Policies [Abstract]  
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
Basis of Presentation

The Consolidated Financial Statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”). The Consolidated Financial Statements include the accounts of the Company, all of the controlled subsidiaries and variable interest entities of which the Company is the primary beneficiary. Noncontrolling interest consists of equity that is not attributable directly or indirectly to the Company. All material intercompany transactions have been eliminated in consolidation. Balances (except per share data) are presented in U.S. dollars and rounded, as indicated. In order to preserve the mathematical accuracy of the underlying calculations, immaterial footing differences may occur between the sum of individual balances and the total balances presented.

Reclassification

With the commencement of the current fiscal year, the Company has made certain reclassifications to the income statement to provide more transparency into the Company’s streams of revenue and to increase comparability with peers. This reclassification has been applied retrospectively, and comparative figures for prior periods have been adjusted accordingly within the accompanying Consolidated Financial Statements. The reclassification does not affect the Company’s Net income.
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 Consolidated Financial Statements. Significant estimates inherent in the preparation of the accompanying audited Consolidated Financial Statements include healthcare costs incurred but not yet reported (“IBNR”) and risk adjustment transfers. Estimates are based on past experience and other considerations reasonable under the circumstances. Actual results may differ materially from these estimates.

Segment Information

Oscar operates as one reportable segment to sell insurance to its members through the federal and state-run healthcare exchanges formed in conjunction with the ACA and leverages its technology platform to provide services via its +Oscar Offering. The Company determined that our 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.

Revenue

Premium
Premium revenue includes direct policy premiums collected directly from members and subsidies received from the Centers for Medicare & Medicaid Services (“CMS”) as part of the Advanced Premium Tax Credit (“APTC”) and Medicare Advantage programs, along with assumed premiums from the Company's reinsurance agreement. Premium revenue is adjusted for the estimated impact of the risk adjustment program required by CMS. Total premiums earned is net of ceded premium from excess of loss (“XOL”) and run-off quota share reinsurance contracts accounted for under reinsurance accounting.

The Company receives a fixed premium per member per month and recognizes premium revenue during the period in which it is obligated to provide services to its members. For direct policy premiums received from CMS, revenue is recorded based on membership and eligibility criteria provided by CMS and is subject to monthly adjustment by CMS.

The Company conducts business through the federal and state-run healthcare exchanges formed in conjunction with ACA and is therefore subject to certain risk stabilization programs and fees established by ACA, such as: Risk Adjustment and Minimum Medical Loss Ratio (“MLR”) requirements.

The ACA risk adjustment program is administered federally by CMS. 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 relative to the estimated market average risk score, when applied to the statewide average premium, will have a risk adjustment payable into the pool. Inversely, plans with higher than average risk scores relative to the estimated market average risk score, when applied to the statewide average premium, will have a risk adjustment receivable from the pool.

Management develops its membership risk scores for the risk adjustment payable using actuarial methodologies and assumptions and by analyzing member data, including demographic and projections of claims data expected to be submitted by the Company to CMS for settlement. Generally, the estimated market average risk score and statewide average premium are obtained from third party surveys of other insurance plans. There is judgment in estimating the Company’s membership risk scores and the estimated market average risk scores. Management refines its estimate as new information becomes available and the final report on actual market risk scores is received from CMS in June of the following year.

In addition, CMS and the Office of Inspector General for Health and Human Services (“HHS”) perform risk adjustment data validation (“RADV”) audits of health insurance plans to validate the coding practices of and supporting documentation maintained by healthcare providers, and such audits have in the past and may in the future result in adjustments to risk transfer payments.

The ACA established a minimum MLR ratio that requires insurers to pay rebates to customers when MLR is below established thresholds. The medical loss ratio represents medical costs as a percentage of premium revenue. Federal regulations define what constitutes medical costs and premium revenue for purposes of calculating the required minimum MLR. The Company records estimated MLR rebates as an adjustment to premium revenue.

Services and Other

The Company earns revenue as part of services performed via the +Oscar platform. Services 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. Other revenue includes primarily sublease income.

Reinsurance

The Company participates in reinsurance agreements to limit risk and meet its capital requirements. The Company currently enters into two different types of arrangements: quota share reinsurance contracts that do not meet risk transfer requirements and XOL reinsurance contracts.

The quota share reinsurance contracts are accounted for under the deposit accounting method. Under deposit accounting, the contract is recorded as a financing, with no impact to premium revenue or medical expenses. 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. Premiums under XOL reinsurance agreements are based on enrollment calculated on a per member per month basis. The XOL contracts are accounted for under reinsurance accounting and, as such, the Company records premium paid to the reinsurer as a reduction to premium revenue. In the case of federal and state-run reinsurance programs, no reinsurance premiums are paid. Expected reimbursement from the reinsurer for claims incurred are recorded as a reduction to medical expenses.
Reinsurance contracts are renewed periodically and we review them in advance of the contract’s expiration to negotiate terms for new reinsurance contracts. During each renewal cycle, there are a number of factors considered when determining reinsurance coverage, including (1) plans to change the underlying insurance coverage offered by the Company, (2) trends in loss activity, (3) the level of the insurance subsidiaries' capital and surplus, (4) changes in the Company's risk appetite, and (5) the cost and availability of reinsurance coverage.

In addition to ceded reinsurance, an Oscar health insurance subsidiary partially reinsures the Cigna+Oscar small group offering through a quota share reinsurance arrangement. The Company records assumed premiums and assumed claims. Refer to Note 11 - Reinsurance for more information.

Premium Deficiency Reserve

Premium deficiency reserve (“PDR”) liabilities are established when it is probable that expected future claims and maintenance expenses will exceed future premium and reinsurance recoveries based on existing insurance contract terms including consideration of net investment income. For purposes of determining premium deficiency reserves, contracts are grouped consistent with the Company’s method of acquiring, servicing, and measuring the profitability of such contracts, which is generally on a line of business basis. The Company records PDR expenses within Selling, general, and administrative expenses on the Consolidated Statements of Operations.

Cash and Cash Equivalents

Cash and cash equivalents consists of highly liquid investments with original maturities of three months or less.

Restricted Deposits
The Company defines restricted deposits as restricted cash, cash equivalents, and investments maintained on deposit or pledged primarily to various state agencies in connection with its insurance licensure. Statutory regulations require these amounts to remain on deposit indefinitely; therefore, the Company classifies these restricted deposits as long-term regardless of the contractual maturity date of the securities held. Restricted cash equivalents and investments are recorded at fair value.

Investments

The majority of the Company's investments are classified as available-for-sale and are carried at fair value. Short-term investments include securities with maturities between three months and one year. Long-term investments include securities with maturities greater than one year.

Under the Company's current expected credit loss (“CECL”) model, the Company evaluates its available-for-sale debt investments for impairment by monitoring the difference between the carrying value and fair value of a security and whether declines in fair value are credit-related. If a security is in an unrealized loss position and the Company has the intent to sell, or it is more likely than not that the security will be sold before recovery of its amortized cost basis, the decline in fair value is recognized as a loss on the income statement. For securities in an unrealized loss position that the Company does not intend to sell, the Company performs an evaluation to determine what portion of the unrealized losses are credit-related; this portion is recognized on the income statement as an allowance for credit losses. The remaining non-credit-related portion of the decline in fair value is recognized as an unrealized loss in Accumulated other comprehensive income (loss).

Allowance for Credit Losses

Premium and other receivables primarily includes insurance premiums due from CMS and members, pharmaceutical rebates, and other claims-related provider receivables and are reported net of any allowance for credit losses. Receivable balances are also recorded related to the Company's risk adjustment program, reinsurance program, and value-based care arrangements. An allowance for credit losses is generally calculated based on historical collection experience, the counterparty's creditworthiness, and consideration of current and future economic events.

As part of value-based care arrangements, the Company entered into risk sharing arrangements with certain of its providers. The intention of these agreements is to align incentives with providers who desire to share accountability for the quality and costs of managing a population of Oscar’s members. If medical expenses exceed agreed upon population-specify target MLR, the provider reimburses the Company an agreed upon portion of the excess expenses creating a risk share receivable due to the Company. The Company recorded risk sharing receivables on a gross basis on the Consolidated Balance Sheet. The Company evaluated expected losses on risk sharing receivables and recorded and adjusted the resulting expected losses to the allowance for credit losses based on the counterparty’s financial health and creditworthiness and any significant changes in the healthcare environment. The Company writes off the receivable balance when it is determined to be uncollectible. The Company has presented the rollforward related to its allowance for credit losses on our risk sharing receivables below:

Policy Acquisition Costs

Policy acquisition costs are those costs that relate directly to the successful acquisition of new and renewal insurance policies. Such costs include broker commissions, costs of policy issuance and underwriting, and other costs incurred to acquire new business or renew existing business. Policy acquisition costs, other than broker bonus commissions, are expensed in the period incurred. Broker bonuses are capitalized and amortized over the policy term. The Company's short-duration policies typically have a one-year term and may be canceled by the member upon 30 days' notice.

Income Taxes

Income taxes are accounted for under the asset and liability method, which requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of events that have been included in the financial statements. Under this method, deferred tax assets and liabilities are determined on the bases of the differences between the financial statements and tax basis of assets and liabilities using enacted tax rates in effect for the year in which the differences are expected to reverse. The effect of a change in tax rates on deferred tax assets and liabilities is recognized in income in the period that includes the enactment date. The Company recognizes net deferred tax assets to the extent that the Company believes these assets are more likely than not to be realized. The Company establishes a valuation allowance when it does not consider it more likely than not that a deferred tax asset will be realized.

Benefits Payable

Benefits payable consists of liabilities for both IBNR and reported but not yet processed through the Company's systems that are determined in the aggregate, employing actuarial methods that are commonly used by health insurance actuaries and meet Actuarial Standards of Practice. Actuarial Standards of Practice require that the claim liabilities be appropriate under moderately adverse circumstances. IBNR is an actuarial estimate, determined by employing actuarial methods, that is based on claim payment patterns, medical cost inflation, historical developments such as claim inventory levels and claim receipt patterns, and other relevant factors.

For low severity incurred but not paid claims, for the months prior to the most recent two months, the Company typically uses the completion factor development method. This methodology is a detailed actuarial process that uses both historical claim payment patterns as well as emerging medical cost trends to project the Company's best estimate of claim liabilities. Under this method, historical paid claims data is formatted into claim triangles, which compare claim incurred dates to the dates of claim payments. This information is analyzed to create historical completion factors that represent the average percentage of total incurred claims that have been paid through a given date after being incurred. Completion factors are applied to claims paid through the period-end date to estimate the ultimate claim expense incurred for the period. Actuarial estimates of incurred but not paid claim liabilities are then determined by subtracting the actual paid claims from the estimate of the ultimate incurred claims. A seriatim methodology is utilized for high dollar claims which is supplemented by case management data supplied by medical and claims operations areas.

For the most recent incurred months (typically the most recent two months), the percentage of claims paid for claims incurred in those months is generally low. This makes the completion factor methodology less reliable for such months. Therefore, incurred claims for recent months are not projected from historical completion and payment patterns; rather, they are primarily based on forecasted per member per month low dollar claims projections developed from the Company’s historical experience and adjusted for emerging experience data in the preceding months, which may include adjustments for known changes in estimates of recent hospital and drug utilization data, provider contracting changes, changes in benefit levels, changes in member cost sharing, changes in medical management processes, product mix, and workday seasonality.

Because the reserve methodology is based upon historical information, it must be adjusted for known or suspected operational and environmental changes. These adjustments are made by the Company's actuaries based on their knowledge and their estimate of emerging impacts to benefit costs and payment speed. Circumstances to be considered in developing the Company's best estimate of reserves include changes in utilization levels, unit costs, member cost sharing, benefit plan designs, provider reimbursement levels, processing system conversions and changes, claim inventory levels, claim processing patterns, and claim submission patterns.

The Company regularly reviews and sets assumptions regarding cost trends and utilization when initially establishing claim liabilities. The Company continually monitors and adjusts the claims liability and benefit expense based on subsequent paid claims activity. If it is determined that the Company's assumptions regarding cost trends and utilization are materially different from actual results, the Company's income statement and financial position could be impacted in future periods. Adjustments of prior year estimates may result in additional benefit expense or a reduction of benefit expense in the period an adjustment is made. Further, due to the considerable variability of healthcare costs, adjustments to claim liabilities occur each period and are sometimes significant as compared to the net income recorded in that period. Prior period development is recognized immediately upon the actuary’s judgment that a portion of the prior period liability is no longer needed or that an additional liability should have been accrued. That determination is made when sufficient information is available to ascertain that the re-estimate of the liability is reasonable.

Disputed Claim Reserves
The Company also records, as part of benefits payable, an estimate of the ultimate liability for actual and potential claims disputes by providers based on an analysis of historical per member per month (“PMPM”) dispute experience supplemented with current information on reported disputes. Since these liabilities are part of the overall claim reserve, they are proportionally ceded under the Company's reinsurance agreements for historical policy years with contracts in force. The disputed claim reserves included as part of the benefits payable balance was approximately $183.7 million and $241.1 million as of December 31, 2024 and 2023, respectively.

Unallocated Claims Adjustment Expenses
Claims adjustment expenses (“CAE”) are costs incurred or expected to be incurred in connection with the adjustment and recording of health claims not subject to reinsurance. Such expenses include, but are not limited to, case management, utilization review, and quality assurance and are intended to reduce the number of health services provided or the cost of such services. CAE is included in other insurance costs and the related CAE payable is included in accounts payable and accrued liabilities.

Property, Equipment, and Capitalized Software

Property, equipment, and capitalized software are reported at cost less accumulated depreciation. Depreciation and amortization is calculated on a straight-line basis over the estimated useful lives of the related assets, which range from two to ten years. Costs related to certain software projects for internal use incurred during the application development stage are capitalized. Costs related to planning activities and post-implementation activities are expensed as incurred. Internal-use software is amortized on a straight-line basis over its estimated useful life, which ranges from three to seven years. Property, equipment, and capitalized software are assessed for impairment whenever events or circumstances suggest that an asset's carrying value may not be fully recoverable.

Leases

The Company leases office space under operating leases expiring on various dates through 2032. On the lease commencement date, a right-of-use (“ROU”) asset and lease liability are recognized as Other assets and Other Liabilities on the Consolidated Balance Sheets based on the present value of the future minimum lease payments over the lease term. Since the Company's lease agreements do not provide an implicit rate, an incremental borrowing rate, based on the information available at commencement date, is used to determine the present value of future payments. The calculation of the ROU asset is based on the lease liability, and includes any lease payments made, and excludes lease incentives and initial direct costs incurred.

The Company determines if an arrangement is a lease or contains a lease at inception of the arrangement based on the terms and conditions in the contract. Options to extend or terminate a lease at the Company's discretion are factored into the calculation of the lease liabilities and ROU assets only if the Company is reasonably certain it will exercise those options. Short-term leases with an initial term of twelve months or less are not recorded on the balance sheet.

Lease expense for the Company's operating leases is calculated on a straight-line basis over the lease term.within Selling, general, and administrative expenses on the Consolidated Statements of Operations. Lease and non-lease components are accounted for as a single lease component for all asset classes.

Earnings Per Share

Earnings (loss) per share (“EPS”) is calculated using the two-class method, which is an earnings allocation model that treats participating securities as having rights to earnings that otherwise would have been available to common stockholders. Under the two-class method, earnings for the period are required to be allocated between common stock and participating securities based upon their respective rights to receive distributed and undistributed earnings. For EPS computation purposes, the Company's Class A and Class B common stock are considered one single class of common stock because both classes have the same dividend and liquidation rights. Refer to Note 3 - Earnings (Loss) Per Share for a description of our basic and diluted EPS calculations.

Variable Interest Entities

The Company enters arrangements with various entities that are deemed to be variable interest entities (“VIE”). A VIE is an entity that either (1) has equity investors that lack certain essential characteristics of a controlling financial interest (including the ability to control activities of the entity, the obligation to absorb the entity’s expected losses, and the right to receive the entity’s expected residual returns) or (2) lacks sufficient equity to finance its own activities without financial support provided by other entities, which in turn would be expected to absorb at least some of the expected losses of the VIE. The Company is deemed a primary beneficiary of a VIE if it has (1) the power to direct the activities of the VIE that most significantly impact the economic performance of the VIE and (2) the obligation to absorb losses of, or the right to receive benefits from, the VIE that could be potentially significant to the VIE. If both conditions are present, the Company is required to consolidate the VIE into its financial results.

Earnings Per Share [Abstract]  
EARNINGS (LOSS) PER SHARE EARNINGS (LOSS) PER SHARE
Basic 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 dividing Net income attributable to Oscar Health, Inc. 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 9 - Debt. Potential common stock includes the effect of outstanding dilutive stock options, restricted stock units and,
performance-based restricted stock units. For the year ended December 31, 2024, the impact of convertible senior notes was anti-dilutive on dilutive EPS, and therefore excluded from the computation below. The computation for basic and diluted EPS is as follows:

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.

The amortized cost and fair value of the Company's fixed maturity as of December 31, 2024 and 2023 by contractual maturity are shown below.

Fair Value Disclosures [Abstract]  
FAIR VALUE MEASUREMENTS 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:

Amounts incurred related to prior periods vary from previously estimated liabilities as more claim information becomes available and claims are ultimately settled. The favorable development recognized in the year ended December 31, 2024 resulted primarily from lower than expected paid claims.

The following tables provide information about incurred, paid healthcare claims development, unpaid claims liability, and cumulative claims frequency. The claims development information for all periods preceding the most recent reporting period is considered required unaudited supplementary information. For claims frequency information summarized below, a claim is defined as the financial settlement of a single medical event in which remuneration was paid to the servicing provider. Total IBNR plus expected development on reported claims represents estimates for claims incurred but not reported and development on reported claims. The Company estimates its liability using actuarial methods that are commonly used by health insurance actuaries and meet Actuarial Standards of Practice. These actuarial methods consider factors such as historical data for payment patterns, cost trends, product mix, seasonality, utilization of healthcare services, and other relevant factors.

Convertible Senior Notes

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 “Indenture”). 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 2031 Notes are the Company's senior, unsecured obligations and are (i) equal in right of payment with the Company's existing and future senior, unsecured indebtedness; (ii) senior in right of payment to the Company's existing and future indebtedness that is expressly subordinated to the 2031 Notes; (iii) effectively subordinated to the Company's existing and future secured indebtedness, to the extent of the value of the collateral securing that indebtedness; and (iv) structurally subordinated to all existing and future indebtedness and other liabilities, including trade payables, and (to the extent the Company is not a holder thereof) preferred equity, if any, of the Company's subsidiaries.

The 2031 Notes are convertible into the Company's Class A common stock at initial conversion rates of 120.1721 per $1,000 principal amount (equivalent to an initial conversion price of approximately $8.32 per share of Class A common stock), subject to customary adjustments upon the occurrence of certain events. In addition, upon the occurrence of a make-whole fundamental change, as defined in the Indenture governing the 2031 Notes (the "Indenture"), the Company will, in certain circumstances, increase the conversion rate by a number of additional shares for a holder that elects to convert its 2031 Notes in connection with such make-whole fundamental change.

The 2031 Notes may be converted at the option of the holders, on or after August 31, 2031, if the Company calls the 2031 Notes for redemption, upon the satisfaction of a Class A common stock sale price or 2031 Note trading price condition, or upon certain corporate events. Upon conversion, the 2031 Notes will be settled, at the Company's election, in shares of Class A common stock, cash, or a combination of cash and shares of Class A common stock, 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. During the quarterly period ended December 31, 2024, the Class A stock sale price
condition was satisfied when the last reported sales price per share of the Company’s Class A common stock was greater than 130% of the conversion price of $8.32 per share for each of at least twenty (20) trading days during the period of thirty (30) consecutive trading days ending on, and including, the last trading day of the quarter. As a result, the 2031 Notes are convertible during the first quarter of 2025 at the option of the holders. As of the date of this Annual Report on Form 10-K, the 2031 Notes have not been converted.

Upon the occurrence of a fundamental change (as defined in the 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 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 prior to December 31, 2026. The Company may redeem all, but not less than all, of the 2031 Notes, at the Company's option, on or after December 31, 2026 and on or before the 35th scheduled trading day immediately preceding the maturity date, for a cash purchase price equal to the redemption price, but only if the last reported sale price per share of Class A common stock exceeds 200% of the conversion price on each of at least 20 trading days (whether or not consecutive) during the 30 consecutive trading days ending on, and including, the trading day immediately before the date on which the Company sends the redemption notice for such redemption. 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. Notwithstanding the foregoing, if the Company calls any of the 2031 Notes for redemption the Initial Purchasers have the right to convert the 2031 Notes and to elect to receive the consideration due upon conversion solely in shares of Class A common stock pursuant to the terms of the Investment Agreement.

The 2031 Notes include customary provisions relating to the occurrence of “Events of Default” (as defined in the Indenture), as well as customary covenants for convertible notes of this type, including restrictions on the Company's ability to refinance the Company's indebtedness and incur additional indebtedness.

As of December 31, 2024, the net carrying amount of the 2031 Notes was $299.6 million, with unamortized debt discount and issuance costs of $5.4 million. The Company classified the fair value of the 2031 Notes as a level 3 measurement due to the lack of observable market data over fair value inputs such as our stock price volatility over the term of the 2031 Notes and the Company's cost of debt. The estimated fair value of the 2031 Notes as of December 31, 2024 was $539.8 million.

Revolving Credit Facility

On December 28, 2023, the Company entered into a third amendment to its senior secured credit agreement (the “Third Amendment”), 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 amended by the First Amendment to Credit Agreement, dated as of January 27, 2022, and as further amended by the Second Amendment to Credit Agreement, dated as of July 21, 2023, the “Credit Agreement” and as amended by the Third Amendment, the “Amended Credit Agreement”). The Amended Credit Agreement provides 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.

Under the terms of the Revolving Credit Facility, borrowings under the Revolving Credit Facility bear interest at a rate equal to, at the Company's option, either (a) an adjusted term secured overnight financing rate ("SOFR"), plus an applicable margin of 4.50% (SOFR is calculated based on one-, three- or six-month SOFR, or such other period as agreed by all relevant Lenders, which is determined by reference to the SOFR administrator’s website, but not less than 1.00%), or (b) a rate per annum equal to the Alternate Base Rate, as defined in the Revolving Credit Facility, plus the applicable margin of 3.50%
(the Alternate Base Rate is equal to the highest of (i) the prime rate, (ii) the federal funds effective rate plus 0.50%, and (iii) SOFR based on a one-month interest period, plus 1.00%). The Revolving Credit Facility also includes a commitment fee of 0.50% for available but undrawn amounts and other administrative fees that are payable quarterly.

The Revolving Credit Facility is guaranteed by Oscar Management Corporation, each wholly owned subsidiary of the Company, and all of the Company's future direct and indirect subsidiaries (in each case subject to certain permitted exceptions, including exceptions for guarantees (i) that would require material governmental consents or (ii) in respect of joint ventures) (the "Guarantors"). Oscar Management Corporation is currently the only Guarantor. The Revolving Credit Facility is secured by substantially all of the Company’s and the Guarantors' assets (subject to certain exceptions). The Revolving Credit Facility is available for the Company to borrow under until December 28, 2025, provided the Company is in compliance with the restrictive and financial covenants contained therein, including financial covenants to maintain minimum thresholds related to direct policy premiums, consolidated Adjusted EBITDA (as defined in the Revolving Credit Facility), and liquidity, as well as a maximum medical loss ratio.

The Company is permitted to increase commitments under the Revolving Credit Facility by an aggregate amount not to exceed $50.0 million, subject to certain conditions.

As of December 31, 2024, there were no outstanding borrowings under the Revolving Credit Facility.

2012 Stock Plan

Prior to the initial public offering ("IPO"), the Company maintained the 2012 Stock Plan (the “2012 Plan”), which provided for the grant of incentive stock options ("ISOs"), non-qualified stock options ("NSOs"), common stock of the Company, stock payments and restricted stock units. The 2012 Plan was initially adopted on December 6, 2012, and most recently amended and restated in March 2021. The 2012 Plan was terminated upon the effectiveness of the 2021 Incentive Award Plan in March 2021, and no further awards will be made under the 2012 Plan.

2021 Incentive Award Plan

In March 2021, the Company’s board of directors adopted the 2021 Incentive Award Plan (the “2021 Plan”), which provides for the grant of NSOs, ISOs, stock appreciation rights (“SARs”), restricted stock, restricted stock units (including time-based restricted stock units (“RSUs”), and performance-based restricted stock units (“PSUs”)), dividend equivalents and other stock or cash awards to employees, consultants and non-employee directors. Under the 2021 Plan, there are 49.2 million shares authorized to be issued, with 7.2 million shares still available for future issuance as of December 31, 2024. The shares available for future issuance as of December 31, 2024 may be issued as either Class A common stock or Class B common stock.

2022 Inducement Incentive Award Plan

In April 2022, the Company’s board of directors adopted the 2022 Employment Inducement Incentive Award Plan (the “Inducement Plan”), which provides for the grant of NSOs, SARs, restricted stock, RSUs, PSUs, dividend equivalents and other stock or cash awards to prospective employees. The Inducement Plan was amended on March 28, 2023 to add 13.3 million shares to the plan. Under the Inducement Plan, as of December 31, 2024, there are 18.3 million shares authorized to be issued, with 5.8 million shares still available for future issuance. The shares available for future issuance as of December 31, 2024 may be issued as Class A common stock.
Stock-Based Compensation Expense

Stock-based compensation expense is recognized on a straight-line basis over the requisite service period. Forfeitures are accounted for as they occur. The Company records stock-based compensation expense within Selling, general, and administrative expenses on the Consolidated Statements of Operations. The Company's stock-based compensation expense for the years ended December 31, 2024, 2023, and 2022 was $119.0 million, $166.8 million, and $112.3 million, respectively. The Company capitalized $9.1 million and $7.1 million of stock-based compensation expense related to internally developed software for the years ended December 31, 2024 and 2023, respectively. The Company did not capitalize any stock-based compensation expense for the year ended December 31, 2022.
Stock Options

Stock options granted under the 2012 Plan and 2021 Plan include ISOs and NSOs, generally have a maximum contractual term of 10 years, and typically vest over a four-year period.

The weighted average grant date fair value of options granted during the years ended December 31, 2024 and 2023 was $10.65 and $3.74, respectively. There were no stock options granted during the year ended December 31, 2022. The aggregate intrinsic value of options exercised during the years ended December 31, 2024, 2023 and 2022 was $71.7 million, $8.5 million, and $1.0 million, respectively.

Determination of Fair Value of Stock Options
The fair value of stock options is estimated on the grant date using the Black-Scholes option-pricing model, which takes into account significant assumptions such as the expected term of the option, stock price volatility, and a risk-free rate of return. The Company has used the simplified method in calculating the expected term of all option grants based on the vesting period and contractual term.

The table below summarizes the assumptions used during the years ended December 31, 2024 and 2023. There were no stock options granted during the year ended December 31, 2022.

As of December 31, 2024, the amount of unrecognized compensation expense for stock options is $3.4 million, which is expected to be recognized over a weighted-average period of 2.0 years.

Restricted Stock Units

RSUs represent the right to receive shares of the Company’s Class A or Class B common stock at a specified date in the future and typically have a vesting period of one to four years.
The following table summarizes RSU award activity for the year ended December 31, 2024:

Determination of Fair Value of RSUs
The fair value of RSUs granted is determined on the grant date based on the fair value of the Company's common stock. The total fair value of RSUs vested during the years ended December 31, 2024 and 2023 was $93.6 million and $89.7 million, respectively.

Compensation Expense – RSUs
For the years ended December 31, 2024, 2023 and 2022, the Company recorded compensation expense of $95.0 million, $90.0 million and $65.5 million, respectively. As of December 31, 2024, the amount of unrecognized compensation expense for RSUs is $101.2 million, which is expected to be recognized over a weighted-average period of 1.6 years.

Performance-based Restricted Stock Units

PSUs represent the right to receive shares of the Company’s Class A or Class B common stock at a specified date in the future based on pre-determined performance and service conditions. The PSUs granted include awards with a market condition, which are eligible to vest based on the achievement of predetermined stock price goals, and awards with performance conditions, which are eligible to vest based on the Company’s predetermined financial targets. For PSUs with predetermined financial targets, the number of shares that may vest ranges from 0% to 200% of the target amount. These PSUs cliff vest at the end of a three-year performance period. Additionally, the ultimate payout of the PSUs is subject to a relative total shareholder return (“TSR”) performance modifier, which adjusts the payout level upwards or downwards based on the Company’s shareholder return over the same three-year performance period relative to companies in a peer group established by the Company at the grant date.

Cancellation of the Founders Awards – PSUs
On March 28, 2023, the Company’s Co-Founders, Mario Schlosser (the Company’s President of Technology and Chief Technology Officer and former Chief Executive Officer) and Joshua Kushner (the Company’s Vice Chairman), recommended to the Company’s board of directors that they should cancel and terminate the applicable awards that were granted to them in connection with the Company’s IPO (the “Founders Awards”). Mr. Schlosser and Mr. Kushner each entered into an agreement to cancel and terminate his Founders Award, which consisted of performance-based restricted stock units covering 4,229,853 shares (for Mr. Schlosser) and 2,114,926 shares (for Mr. Kushner) of the Company’s Class A common stock. As a result of this cancellation, the Company recognized approximately $46.3 million of accelerated stock-based compensation expense that would have otherwise been recognized over the remaining vesting period of the awards.

Compensation Expense – PSUs
For the years ended December 31, 2024, 2023 and 2022 the Company recorded compensation expense of $15.3 million, $64.9 million, and $25.3 million respectively. As of December 31, 2024, the amount of unrecognized compensation expense for PSUs is $23.9 million, which is expected to be recognized over a weighted-average period of 1.7 years.

REINSURANCE 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.

The Company also operates under an assumed reinsurance contract, under which the Company shares proportionally in all premiums and claims underwritten for the Cigna+Oscar Small Group offering.

Reinsurance Contracts Accounted for under Deposit Accounting

Reinsurance contracts that do not meet risk transfer requirements are accounted for under the deposit accounting method. Under deposit accounting, the contract is recorded as a financing, with no impact to premium revenues or medical expenses. The premiums earned and claims incurred that would have otherwise been ceded under reinsurance accounting are recorded on a net basis on the Consolidated Balance Sheets as a deposit liability within Accounts payable and other liabilities, respectively. As of December 31, 2024 and December 31, 2023, a deposit liability balance of $13.6 million and $7.0 million, respectively, was recorded for the Company's quota share arrangements accounted for under deposit accounting and represents fees due to the reinsurer, which are recognized within Selling, general, and administrative expenses on the Consolidated Statements of Operations.
For the years ended December 31, 2024, 2023, and 2022, the Company ceded 53%, 45%, and 18% of its premium under reinsurance contracts accounted for under deposit accounting, respectively.

Reinsurance Contracts Accounted for under Reinsurance Accounting

When significant risk is transferred to the reinsurer, reinsurance accounting is required. Reinsurance accounting applies to quota share reinsurance contracts that are in runoff as well as the XOL treaties. Under reinsurance accounting, the Company records premium paid to the reinsurer as a reduction to premium revenue with a corresponding reinsurance payable. In the case of federal and state-run reinsurance programs, no reinsurance premiums are paid. Expected reimbursement from the reinsurer for claims incurred are recorded as a reduction to claims incurred with a corresponding reinsurance recoverable asset. The tables below present information for the Company's reinsurance arrangements accounted for under reinsurance accounting. See Note 4 - Revenue Recognition for total reinsurance premiums ceded and reinsurance premiums assumed, which are included as components of total Premium revenue in the 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 A1 or higher.

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.

The Company evaluates the need for a valuation allowance against its deferred tax assets considering all available positive and negative evidence. Based on its analysis, the Company concluded that it is more likely than not that all or some portion of the deferred tax asset will not be realized. The Company has a valuation allowance of $590.6 million at December 31, 2024 against its deferred tax assets, including federal and state net operating losses, as the Company does not have a history of positive earnings. Valuation allowances will be provided until it becomes more likely than not that the benefit of the federal and state deferred tax assets will be realized.

Federal NOL carryovers are $2,156.8 million, of which $1,249.0 million expire beginning in 2035 through 2043, and $907.8 million have indefinite carryforward periods. State NOL carryforwards from group filings are approximately $1,001.5 million and from separate entity filings are $298.9 million; state NOL carryforwards expire beginning in 2035. Pursuant to I.R.C Section 382, the Company underwent a change in ownership in 2016. Based on the annual limitation, use of pre-change NOL carryforwards will not be limited prior to expiration.

The Company evaluates tax positions to determine whether the benefits are more likely than not to be sustained on audit based on technical merits. The Company did not have any uncertain tax positions for the years ended December 31, 2024, 2023, and 2022. The Company does not expect any significant changes to unrecognized tax benefits in the next twelve months. The Company’s policy is to classify interest accrued related to unrecognized tax benefits in interest expense while penalties are included in income tax expense. The Company had no interest or penalties related to uncertain tax positions.

The Company currently files income tax returns in the United States, various states, and localities. The majority of the Company’s operating subsidiaries are included in a consolidated federal income tax return. The Company began operations in 2012 and has never been placed under income tax audit. Federal tax returns are open for examination for tax years from 2021. State tax returns are open for examination for tax years from 2020.

STATUTORY REGULATIONS
The Company's insurance subsidiaries prepare financial statements in accordance with Statutory Accounting Principles ("SAP") prescribed or permitted by the insurance departments of their states of domicile. SAP are focused on the solvency of insurance companies and are designed to ensure that insurers maintain sufficient capital and surplus to meet their insurance-related obligations.

The Company's insurance subsidiaries are regulated by the state insurance departments of the states in which they are domiciled. Statutory regulations include the establishment of minimum levels of statutory capital to be maintained by insurance subsidiaries and restrictions on dividend payments and other distributions made by the insurance subsidiaries to the parent company. Minimum statutory capital requirements differ by state and are based on minimum risk-based capital ("RBC") requirements developed by the National Association of Insurance Commissioners ("NAIC").
As of December 31, 2024, the Company's insurance subsidiaries are estimated to have an aggregate statutory capital and surplus of approximately $1,242.7 million. As of December 31, 2023, the Company’s insurance subsidiaries had an aggregate statutory capital and surplus of $800.6 million. Individually, each of the Company's insurance subsidiaries is projected to exceed the minimum required statutory capital and surplus and RBC minimum requirements.

Commitments and Contingencies Disclosure [Abstract]  
COMMITMENTS AND CONTINGENCIES 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, 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, 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 IPO was commenced in the United States District Court for the Southern District of New York, 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 asserts 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 seeks unspecified compensatory damages as well as interest, fees, and costs. On April 4, 2023, the Company moved to dismiss the amended complaint. Briefing on the motion was completed on July 7, 2023. The Company believes it has meritorious defenses to these claims. At this time, the Company cannot predict the outcome, or provide a reasonable estimate or range of estimates of the possible outcome or loss, if any, in this matter.

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.

SEGMENT INFORMATION 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 the summary of significant accounting policies. The CODM reviews Net income (loss) attributable to Oscar Health, Inc. and Adjusted EBITDA 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. As part of the adoption of ASU 2023-07, the prior years’ segment information has been disclosed herein to align with the current year’s presentation.

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 Consolidated Statements of Operations.

Cybersecurity Risk Management Processes for Assessing, Identifying, and Managing Threats [Text Block]
Cybersecurity Risk Management and Strategy

We have developed and implemented a cybersecurity risk management program intended to protect the confidentiality, integrity, and availability of our critical systems and information, including protected health information and the systems that store and transmit such data. Our cybersecurity risk management program includes a cybersecurity incident response plan.

We use the ISO 27001 standard as a guide to help us identify, assess, and manage cybersecurity risks relevant to our business. This does not imply that we meet any particular technical standards, specifications or requirements.

Our cybersecurity risk management program is integrated into our overall enterprise risk management program, and shares common methodologies, reporting channels and governance processes that apply across the enterprise risk management program to other legal, compliance, strategic, operational, and financial risk areas.

Our cybersecurity risk management program includes:

risk assessments designed to help identify material cybersecurity risks to our critical systems, information, products, services, and our broader enterprise IT environment;
a security team principally responsible for managing (1) our cybersecurity risk assessment processes, (2) our security controls, and (3) our response to cybersecurity incidents;
the use of external service providers, where appropriate, to assess, test or otherwise assist with aspects of our security controls, and conduct tabletop exercises to validate our cybersecurity incident response processes;
the use of various technology and process-based methods, such as network isolation, intrusion detection systems, vulnerability assessments, penetration testing, use of threat intelligence, content filtering, endpoint security (including anti-malware and detection response capabilities), email security mechanisms, and access control mechanisms;
cybersecurity awareness training of our employees, including incident response personnel and senior management;
a cybersecurity incident response plan that includes procedures for responding to cybersecurity incidents; and
a third-party risk management and diligence process for vendors and service providers.

While we have implemented processes to maintain our cybersecurity risk management program, there can be no assurance that our program, including our controls, procedures and processes, will be fully complied with or that it will be fully effective in protecting the confidentiality, integrity and availability of our critical systems and information.
We have not identified risks from known cybersecurity threats, including as a result of any prior cybersecurity incidents, that have materially affected or are reasonably likely to materially affect us, including our operations, business strategy, results of operations, or financial condition. See Part I, Item 1A “Risk Factors—Risks Related to our Business—If we or our partners or other third parties with whom we collaborate fail to protect confidential information and/or sustain a data security incident, we could suffer increased costs, material financial penalties, exposure to significant liability, adverse regulatory consequences, and reputational harm, which would materially adversely affect our business, results of operations, and financial condition.”

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Policies)
12 Months Ended
Dec. 31, 2024
Accounting Policies [Abstract]  
Basis of Presentation
The Consolidated Financial Statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”). The Consolidated Financial Statements include the accounts of the Company, all of the controlled subsidiaries and variable interest entities of which the Company is the primary beneficiary. Noncontrolling interest consists of equity that is not attributable directly or indirectly to the Company. All material intercompany transactions have been eliminated in consolidation. Balances (except per share data) are presented in U.S. dollars and rounded, as indicated. In order to preserve the mathematical accuracy of the underlying calculations, immaterial footing differences may occur between the sum of individual balances and the total balances presented.
Reclassification
With the commencement of the current fiscal year, the Company has made certain reclassifications to the income statement to provide more transparency into the Company’s streams of revenue and to increase comparability with peers. This reclassification has been applied retrospectively, and comparative figures for prior periods have been adjusted accordingly within the accompanying Consolidated Financial Statements. The reclassification does not affect the Company’s Net income.
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 Consolidated Financial Statements. Significant estimates inherent in the preparation of the accompanying audited Consolidated Financial Statements include healthcare costs incurred but not yet reported (“IBNR”) and risk adjustment transfers. Estimates are based on past experience and other considerations reasonable under the circumstances. Actual results may differ materially from these estimates.
Segment Information
Oscar operates as one reportable segment to sell insurance to its members through the federal and state-run healthcare exchanges formed in conjunction with the ACA and leverages its technology platform to provide services via its +Oscar Offering. The Company determined that our 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.
Revenue
Premium
Premium revenue includes direct policy premiums collected directly from members and subsidies received from the Centers for Medicare & Medicaid Services (“CMS”) as part of the Advanced Premium Tax Credit (“APTC”) and Medicare Advantage programs, along with assumed premiums from the Company's reinsurance agreement. Premium revenue is adjusted for the estimated impact of the risk adjustment program required by CMS. Total premiums earned is net of ceded premium from excess of loss (“XOL”) and run-off quota share reinsurance contracts accounted for under reinsurance accounting.

The Company receives a fixed premium per member per month and recognizes premium revenue during the period in which it is obligated to provide services to its members. For direct policy premiums received from CMS, revenue is recorded based on membership and eligibility criteria provided by CMS and is subject to monthly adjustment by CMS.
The Company earns revenue as part of services performed via the +Oscar platform. Services 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. Other revenue includes primarily sublease income.
Affordable Care Act (“ACA”)
The Company conducts business through the federal and state-run healthcare exchanges formed in conjunction with ACA and is therefore subject to certain risk stabilization programs and fees established by ACA, such as: Risk Adjustment and Minimum Medical Loss Ratio (“MLR”) requirements.

The ACA risk adjustment program is administered federally by CMS. 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 relative to the estimated market average risk score, when applied to the statewide average premium, will have a risk adjustment payable into the pool. Inversely, plans with higher than average risk scores relative to the estimated market average risk score, when applied to the statewide average premium, will have a risk adjustment receivable from the pool.

Management develops its membership risk scores for the risk adjustment payable using actuarial methodologies and assumptions and by analyzing member data, including demographic and projections of claims data expected to be submitted by the Company to CMS for settlement. Generally, the estimated market average risk score and statewide average premium are obtained from third party surveys of other insurance plans. There is judgment in estimating the Company’s membership risk scores and the estimated market average risk scores. Management refines its estimate as new information becomes available and the final report on actual market risk scores is received from CMS in June of the following year.

In addition, CMS and the Office of Inspector General for Health and Human Services (“HHS”) perform risk adjustment data validation (“RADV”) audits of health insurance plans to validate the coding practices of and supporting documentation maintained by healthcare providers, and such audits have in the past and may in the future result in adjustments to risk transfer payments.

The ACA established a minimum MLR ratio that requires insurers to pay rebates to customers when MLR is below established thresholds. The medical loss ratio represents medical costs as a percentage of premium revenue. Federal regulations define what constitutes medical costs and premium revenue for purposes of calculating the required minimum MLR. The Company records estimated MLR rebates as an adjustment to premium revenue.
Reinsurance
The Company participates in reinsurance agreements to limit risk and meet its capital requirements. The Company currently enters into two different types of arrangements: quota share reinsurance contracts that do not meet risk transfer requirements and XOL reinsurance contracts.

The quota share reinsurance contracts are accounted for under the deposit accounting method. Under deposit accounting, the contract is recorded as a financing, with no impact to premium revenue or medical expenses. 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. Premiums under XOL reinsurance agreements are based on enrollment calculated on a per member per month basis. The XOL contracts are accounted for under reinsurance accounting and, as such, the Company records premium paid to the reinsurer as a reduction to premium revenue. In the case of federal and state-run reinsurance programs, no reinsurance premiums are paid. Expected reimbursement from the reinsurer for claims incurred are recorded as a reduction to medical expenses.
Reinsurance contracts are renewed periodically and we review them in advance of the contract’s expiration to negotiate terms for new reinsurance contracts. During each renewal cycle, there are a number of factors considered when determining reinsurance coverage, including (1) plans to change the underlying insurance coverage offered by the Company, (2) trends in loss activity, (3) the level of the insurance subsidiaries' capital and surplus, (4) changes in the Company's risk appetite, and (5) the cost and availability of reinsurance coverage.
In addition to ceded reinsurance, an Oscar health insurance subsidiary partially reinsures the Cigna+Oscar small group offering through a quota share reinsurance arrangement. The Company records assumed premiums and assumed claims.
Premium Deficiency Reserve Premium deficiency reserve (“PDR”) liabilities are established when it is probable that expected future claims and maintenance expenses will exceed future premium and reinsurance recoveries based on existing insurance contract terms including consideration of net investment income. For purposes of determining premium deficiency reserves, contracts are grouped consistent with the Company’s method of acquiring, servicing, and measuring the profitability of such contracts, which is generally on a line of business basis.
Cash and Cash Equivalents
Cash and cash equivalents consists of highly liquid investments with original maturities of three months or less.
Restricted Deposits
The Company defines restricted deposits as restricted cash, cash equivalents, and investments maintained on deposit or pledged primarily to various state agencies in connection with its insurance licensure. Statutory regulations require these amounts to remain on deposit indefinitely; therefore, the Company classifies these restricted deposits as long-term regardless of the contractual maturity date of the securities held. Restricted cash equivalents and investments are recorded at fair value.
Investments
The majority of the Company's investments are classified as available-for-sale and are carried at fair value. Short-term investments include securities with maturities between three months and one year. Long-term investments include securities with maturities greater than one year.
Under the Company's current expected credit loss (“CECL”) model, the Company evaluates its available-for-sale debt investments for impairment by monitoring the difference between the carrying value and fair value of a security and whether declines in fair value are credit-related. If a security is in an unrealized loss position and the Company has the intent to sell, or it is more likely than not that the security will be sold before recovery of its amortized cost basis, the decline in fair value is recognized as a loss on the income statement. For securities in an unrealized loss position that the Company does not intend to sell, the Company performs an evaluation to determine what portion of the unrealized losses are credit-related; this portion is recognized on the income statement as an allowance for credit losses. The remaining non-credit-related portion of the decline in fair value is recognized as an unrealized loss in Accumulated other comprehensive income (loss).
Allowance for Credit Losses
Premium and other receivables primarily includes insurance premiums due from CMS and members, pharmaceutical rebates, and other claims-related provider receivables and are reported net of any allowance for credit losses. Receivable balances are also recorded related to the Company's risk adjustment program, reinsurance program, and value-based care arrangements. An allowance for credit losses is generally calculated based on historical collection experience, the counterparty's creditworthiness, and consideration of current and future economic events.
Policy Acquisition Cost
Policy acquisition costs are those costs that relate directly to the successful acquisition of new and renewal insurance policies. Such costs include broker commissions, costs of policy issuance and underwriting, and other costs incurred to acquire new business or renew existing business. Policy acquisition costs, other than broker bonus commissions, are expensed in the period incurred. Broker bonuses are capitalized and amortized over the policy term. The Company's short-duration policies typically have a one-year term and may be canceled by the member upon 30 days' notice.
Income Taxes Income taxes are accounted for under the asset and liability method, which requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of events that have been included in the financial statements. Under this method, deferred tax assets and liabilities are determined on the bases of the differences between the financial statements and tax basis of assets and liabilities using enacted tax rates in effect for the year in which the differences are expected to reverse. The effect of a change in tax rates on deferred tax assets and liabilities is recognized in income in the period that includes the enactment date. The Company recognizes net deferred tax assets to the extent that the Company believes these assets are more likely than not to be realized. The Company establishes a valuation allowance when it does not consider it more likely than not that a deferred tax asset will be realized.
Benefits Payable
Benefits payable consists of liabilities for both IBNR and reported but not yet processed through the Company's systems that are determined in the aggregate, employing actuarial methods that are commonly used by health insurance actuaries and meet Actuarial Standards of Practice. Actuarial Standards of Practice require that the claim liabilities be appropriate under moderately adverse circumstances. IBNR is an actuarial estimate, determined by employing actuarial methods, that is based on claim payment patterns, medical cost inflation, historical developments such as claim inventory levels and claim receipt patterns, and other relevant factors.

For low severity incurred but not paid claims, for the months prior to the most recent two months, the Company typically uses the completion factor development method. This methodology is a detailed actuarial process that uses both historical claim payment patterns as well as emerging medical cost trends to project the Company's best estimate of claim liabilities. Under this method, historical paid claims data is formatted into claim triangles, which compare claim incurred dates to the dates of claim payments. This information is analyzed to create historical completion factors that represent the average percentage of total incurred claims that have been paid through a given date after being incurred. Completion factors are applied to claims paid through the period-end date to estimate the ultimate claim expense incurred for the period. Actuarial estimates of incurred but not paid claim liabilities are then determined by subtracting the actual paid claims from the estimate of the ultimate incurred claims. A seriatim methodology is utilized for high dollar claims which is supplemented by case management data supplied by medical and claims operations areas.

For the most recent incurred months (typically the most recent two months), the percentage of claims paid for claims incurred in those months is generally low. This makes the completion factor methodology less reliable for such months. Therefore, incurred claims for recent months are not projected from historical completion and payment patterns; rather, they are primarily based on forecasted per member per month low dollar claims projections developed from the Company’s historical experience and adjusted for emerging experience data in the preceding months, which may include adjustments for known changes in estimates of recent hospital and drug utilization data, provider contracting changes, changes in benefit levels, changes in member cost sharing, changes in medical management processes, product mix, and workday seasonality.

Because the reserve methodology is based upon historical information, it must be adjusted for known or suspected operational and environmental changes. These adjustments are made by the Company's actuaries based on their knowledge and their estimate of emerging impacts to benefit costs and payment speed. Circumstances to be considered in developing the Company's best estimate of reserves include changes in utilization levels, unit costs, member cost sharing, benefit plan designs, provider reimbursement levels, processing system conversions and changes, claim inventory levels, claim processing patterns, and claim submission patterns.

The Company regularly reviews and sets assumptions regarding cost trends and utilization when initially establishing claim liabilities. The Company continually monitors and adjusts the claims liability and benefit expense based on subsequent paid claims activity. If it is determined that the Company's assumptions regarding cost trends and utilization are materially different from actual results, the Company's income statement and financial position could be impacted in future periods. Adjustments of prior year estimates may result in additional benefit expense or a reduction of benefit expense in the period an adjustment is made. Further, due to the considerable variability of healthcare costs, adjustments to claim liabilities occur each period and are sometimes significant as compared to the net income recorded in that period. Prior period development is recognized immediately upon the actuary’s judgment that a portion of the prior period liability is no longer needed or that an additional liability should have been accrued. That determination is made when sufficient information is available to ascertain that the re-estimate of the liability is reasonable.

Disputed Claim Reserves
The Company also records, as part of benefits payable, an estimate of the ultimate liability for actual and potential claims disputes by providers based on an analysis of historical per member per month (“PMPM”) dispute experience supplemented with current information on reported disputes. Since these liabilities are part of the overall claim reserve, they are proportionally ceded under the Company's reinsurance agreements for historical policy years with contracts in force. The disputed claim reserves included as part of the benefits payable balance was approximately $183.7 million and $241.1 million as of December 31, 2024 and 2023, respectively.

Unallocated Claims Adjustment Expenses
Claims adjustment expenses (“CAE”) are costs incurred or expected to be incurred in connection with the adjustment and recording of health claims not subject to reinsurance. Such expenses include, but are not limited to, case management, utilization review, and quality assurance and are intended to reduce the number of health services provided or the cost of such services. CAE is included in other insurance costs and the related CAE payable is included in accounts payable and accrued liabilities.
Property, Equipment and Capitalized Software
Property, equipment, and capitalized software are reported at cost less accumulated depreciation. Depreciation and amortization is calculated on a straight-line basis over the estimated useful lives of the related assets, which range from two to ten years. Costs related to certain software projects for internal use incurred during the application development stage are capitalized. Costs related to planning activities and post-implementation activities are expensed as incurred. Internal-use software is amortized on a straight-line basis over its estimated useful life, which ranges from three to seven years. Property, equipment, and capitalized software are assessed for impairment whenever events or circumstances suggest that an asset's carrying value may not be fully recoverable.
Leases
The Company leases office space under operating leases expiring on various dates through 2032. On the lease commencement date, a right-of-use (“ROU”) asset and lease liability are recognized as Other assets and Other Liabilities on the Consolidated Balance Sheets based on the present value of the future minimum lease payments over the lease term. Since the Company's lease agreements do not provide an implicit rate, an incremental borrowing rate, based on the information available at commencement date, is used to determine the present value of future payments. The calculation of the ROU asset is based on the lease liability, and includes any lease payments made, and excludes lease incentives and initial direct costs incurred.

The Company determines if an arrangement is a lease or contains a lease at inception of the arrangement based on the terms and conditions in the contract. Options to extend or terminate a lease at the Company's discretion are factored into the calculation of the lease liabilities and ROU assets only if the Company is reasonably certain it will exercise those options. Short-term leases with an initial term of twelve months or less are not recorded on the balance sheet.
Lease expense for the Company's operating leases is calculated on a straight-line basis over the lease term.within Selling, general, and administrative expenses on the Consolidated Statements of Operations. Lease and non-lease components are accounted for as a single lease component for all asset classes.
Earnings Per Share
Earnings (loss) per share (“EPS”) is calculated using the two-class method, which is an earnings allocation model that treats participating securities as having rights to earnings that otherwise would have been available to common stockholders. Under the two-class method, earnings for the period are required to be allocated between common stock and participating securities based upon their respective rights to receive distributed and undistributed earnings. For EPS computation purposes, the Company's Class A and Class B common stock are considered one single class of common stock because both classes have the same dividend and liquidation rights. Refer to Note 3 - Earnings (Loss) Per Share for a description of our basic and diluted EPS calculations.
Variable Interest Entities
The Company enters arrangements with various entities that are deemed to be variable interest entities (“VIE”). A VIE is an entity that either (1) has equity investors that lack certain essential characteristics of a controlling financial interest (including the ability to control activities of the entity, the obligation to absorb the entity’s expected losses, and the right to receive the entity’s expected residual returns) or (2) lacks sufficient equity to finance its own activities without financial support provided by other entities, which in turn would be expected to absorb at least some of the expected losses of the VIE. The Company is deemed a primary beneficiary of a VIE if it has (1) the power to direct the activities of the VIE that most significantly impact the economic performance of the VIE and (2) the obligation to absorb losses of, or the right to receive benefits from, the VIE that could be potentially significant to the VIE. If both conditions are present, the Company is required to consolidate the VIE into its financial results.
Accounting Pronouncements Recently Adopted and Accounting Pronouncements Not Yet Adopted
In November 2023, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update No. 2023-07 (“ASU 2023-07”), Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures, which requires, for each reportable segment, disclosure of significant segment expense categories, other segment items, enhanced interim disclosures of certain segment-related disclosures that previously were only required annually, and other disclosure requirements. This guidance is effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024, with early adoption permitted. The Company adopted ASU 2023-07 and provided additional segment footnote disclosures in the Company's annual Consolidated Financial Statements for the year ending December 31, 2024. In addition, the Company provided enhanced disclosures regarding the measure of profit or loss reviewed by the CODM as well as enhanced expense disclosures.
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. While the standard will require additional disclosures related to the Company’s income taxes, 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 before it becomes effective for the Company’s 2025 annual financial statements.

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 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. The Company is currently evaluating the impact of the adoption of this guidance on the Consolidated Financial Statements.
Fair Value 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.

Earnings Per Share [Abstract]  
Schedule of basic and diluted earnings per share
Basic 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 dividing Net income attributable to Oscar Health, Inc. 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 9 - Debt. Potential common stock includes the effect of outstanding dilutive stock options, restricted stock units and,
performance-based restricted stock units. For the year ended December 31, 2024, the impact of convertible senior notes was anti-dilutive on dilutive EPS, and therefore excluded from the computation below. The computation for basic and diluted EPS is as follows:
