Clover Health's 87.6% Benefit Ratio Funds 49% MA Growth

Clover Health's Medicare Advantage membership reached 157,309 in the second quarter, up 49% year over year, while its insurance benefit expense ratio improved to 87.6% from 88.4% and GAAP net income turned to $28.0 million from an $11 million loss a year earlier (Clover Health, August 5, 2026).

Adding tens of thousands of costlier first-year members while improving the aggregate ratio is arithmetically awkward. How it happened is the story.

Key Takeaways

28% of current membership joined in 2026, the highest-cost phase of the relationship, and is tracking in line with the company's expected early-life utilization pattern.
Roughly $70 per member per month of gross profit improvement is what Clover expects between a cohort's first and second year. That maturation, not medical management alone, carried the 80-basis-point move.
UnitedHealth's 86.7% included $860 million of favorable medical reserve development, most of it tied to 2026 dates of service, alongside a 965,000-member decline since year-end 2025.
$120 million of 2027 Quality Bonus Payments rests on a 4.5-star recalculation that CMS appealed to the Eleventh Circuit on July 21, 2026.

What Produced the 80 Basis Points

Clover's book splits into two cohorts with opposite economics. Members enrolled in 2026 make up 28% of current membership and sit in the costliest phase of the relationship, because a new member's chronic conditions have not yet been fully coded and their care has not yet been routed through Clover's primary-care network (Q2 2026 earnings call, August 12, 2026). Members who joined in 2025 are in their second year and producing, in management's words, "meaningfully stronger economics."

That maturation curve is the mechanical answer to how a plan adds costlier new members and still improves its aggregate ratio: the improvement in the aging book has to outrun the drag from the newest one. Clover puts the gap at roughly $70 per member per month of gross profit between a cohort's first and second year.

It worked this quarter. Consolidated gross profit reached $153 million, up 54% year over year, while selling, general and administrative expense fell to 15.1% of revenue for the first half from 17.3%, spreading a largely fixed corporate cost base across a membership base that grew nearly half again in size. Adjusted EBITDA was $41 million, up 139%, on total revenue of $743.2 million, up 56%.

Cash and investments stood at $443 million with zero debt outstanding, up $53.7 million year over year on first-half operating cash flow of $133.1 million, reversing a $10.9 million outflow in the same period of 2025. Full-year guidance now calls for revenue of $2.92 billion to $3.0 billion, adjusted EBITDA of $70 million to $85 million and GAAP net income of $20 million to $35 million on average membership of 156,000 to 158,000.

Three Ratios, Three Different Mechanisms

The three carriers reporting Medicare Advantage results this summer land within five points of each other by entirely different routes. UnitedHealth's medical benefit ratio was 86.7%, improved from 89.4%, but the result included $860 million of favorable medical reserve development, most of it tied to 2026 dates of service (UnitedHealth Group quarterly filing). It also bought part of that ratio by shrinking, with membership down 965,000 since year-end 2025 and guidance pointing to roughly a 1.1 million decline for the full year.

Humana moved the opposite way while growing. Its insurance segment benefit ratio reached 91.2% against 89.9% a year earlier, which the company attributed to the Bonus Year 2026 Star Ratings revenue headwind, higher-cost new Medicare Advantage members and lower prior-period reserve development (decomposition of the Humana filing). Individual Medicare Advantage membership grew roughly 25% year over year even as Humana narrowed to 85% of US counties for 2026 from 89% in 2025 (Kiplinger, 2026).

Carrier	Q2 2026 Benefit Ratio	Change YoY	MA Membership Trend
UnitedHealth	86.7%	Improved from 89.4%, aided by $860M favorable reserve development	Down 965,000 since YE2025
Clover Health	87.6%	Improved from 88.4%, driven by cohort maturation	Up 49% YoY to 157,309
Humana	91.2%	Worsened from 89.9%, driven by Star Ratings headwind and new-member mix	Individual MA up ~25% YoY

Clover's 87.6% arrived without a comparable reserve release and without the Star Ratings drag, which makes it the only one of the three produced primarily by mix. That is the distinction that matters for a bid actuary: a ratio carried by cohort maturation improves only while the share of first-year members is falling. Full-year guidance of 156,000 to 158,000 average members against a 157,309 second-quarter actual implies growth decelerating into the second half, which mechanically shifts weight toward the seasoned cohorts.

Where the members came from matters for the same reason. Medicare Advantage enrollment reached 35.2 million beneficiaries in 2026, 55% of 64.2 million eligible (KFF), and Clover's gains concentrate in New Jersey and Georgia rather than in the counties UnitedHealth and Humana are vacating. A carrier absorbing forced switchers from a giant's county exit underwrites a population with less claims history behind it than an organically acquired member.

What 49% Growth Does to Reserves and Statutory Capital

Clover's outperformance came from "favorable medical cost trend development," the phrase the industry uses for claims arriving lighter than reserved. That is a genuine improvement when it reflects better care management and a measurement artifact when it reflects reserves that were simply set conservatively, and 28% of the book has not completed a full claims run-off cycle, which is exactly the base needed to tell the two apart.

UnitedHealth's $860 million shows how large that swing factor runs even at a carrier with decades of Medicare Advantage claims history. A plan growing 49% a year has a thinner matured base on its newest cohorts, so the same phrase carries more estimation uncertainty at Clover than at the carrier sitting next to it in the table.

The capital side runs on the same timing mismatch. Risk-based capital requirements build against reserves the moment a member enrolls, while the offsetting profit is recognized only as claims experience emerges over the following months. A plan growing 49% year over year books statutory reserves against nearly a full year of premium on its newest cohort within weeks of enrollment, and the favorable experience that validates those reserves takes most of a plan year to develop. Zero funded debt and $443 million of cash are what fund that gap.

The one input that could ease the arithmetic is the least secure. Clover's largest contract moved from 3.5 stars to 4.5 after a federal court ordered CMS to recalculate the rating without the disputed measures, worth an estimated $120 million in 2027 Quality Bonus Payments (Healthcare Dive), and CMS appealed to the Eleventh Circuit on July 21, 2026. CEO Andrew Toy's own framing is the conservative one: the rating "does not create the economics of our model" (Fierce Healthcare).
