The New York-based insurer posted a net loss of $352.6 million, or $1.24 per share, more than doubling the $153.5 million loss recorded during the same period last year. The results fell significantly short of FactSet analyst projections, which had anticipated a more modest loss of 89 cents per share. While fourth-quarter revenue grew to $2.81 billion, it failed to meet the $3.11 billion consensus estimate.

Surging Medical Payouts

The primary driver behind the widening deficit was a sharp spike in the medical loss ratio (MLR), which tracks the portion of premiums paid out for healthcare services. Oscar's MLR hit 95.4% in the fourth quarter, far exceeding the 91.1% analysts had modeled. This surge reflects a broader industry trend where insurers are grappling with increased medical service utilization. Industry giants like UnitedHealth Group have reported similar pressure as an aging U.S. population seeks more frequent medical care, according to market reports.

2026 Financial Targets

Despite the quarterly setback, the company provided a roadmap for its mid-term recovery, signaling a return to operational stability. For the full year 2026, Oscar management is targeting:

• Operating earnings between $250 million and $450 million.
• Total revenue in the range of $18.7 billion to $19 billion.
• A normalized medical loss ratio between 82.4% and 83.4%.

Management's outlook suggests a reliance on stabilizing utilization rates and refined pricing strategies to offset the current volatility in the health insurance market.
