SEGMENT

Assumed Premiums Earned

Premiums Oscar assumes under its reinsurance arrangement for the former Cigna+Oscar small-group plans. The partnership ended in 2024, but transition and run-off adjustments can continue through 2026 and may produce small positive or negative amounts.

COMPANY KPI

Cigna Oscar Members

Effectuated members in the former Cigna+Oscar co-branded small-group health plans. Oscar did not renew the arrangement after December 31, 2024, so later disclosures use a dash rather than reporting zero members.

COMPANY KPI

Medical Loss Ratio

Oscar's medical expenses divided by net premiums before ceded quota-share reinsurance, with federal risk-adjustment transfers included in the premium denominator. The ratio shows how much premium is consumed by members' healthcare costs, so a lower value generally leaves more to cover administration and profit.

SEGMENT

Net Risk Adjustment And Corridor Premiums Earned

Adjustment to Oscar premium revenue for federal risk-adjustment transfers and related corridor items. Plans whose members are estimated to be healthier than their state market generally pay into the CMS pool, producing a negative amount for Oscar, while higher-risk plans may receive funds.

SEGMENT

Premiums Before Ceded Reinsurance

Oscar's direct and assumed premiums after risk-adjustment and corridor transfers but before subtracting premiums paid to reinsurers. This subtotal is the pre-ceding step in the reconciliation to net premium revenue.

SEGMENT

Reinsurance Premiums Ceded

Premiums Oscar pays to reinsurers to transfer part of its health-claim risk under excess-of-loss and run-off quota-share arrangements. The amount appears as a negative adjustment in the premium reconciliation because it reduces premium retained by Oscar.
