Humana stock (HUM) climbs 3% as 2027 COLA calculations obscure rising medical-cost shortfall

LOUISVILLE, Kentucky, Aug. 12, 2026, 11:48 EDT

  • July’s CPI-W indicates a tentative Social Security COLA for 2027 of about 3.1%.
  • Medical-care services increased by 0.6% in July, as the CPI-W showed no change.
  • Shares of Humana increased 2.6% to $382.52 as of 11:14 a.m. EDT.

Shares of Humana Inc. gained on Wednesday, coinciding with heightened interest in the 2027 Social Security cost-of-living adjustment. The latest CPI-W figure for July suggests an initial increase of around 3.1%. Still, the principal challenge for the Medicare insurer lies in healthcare expenses rather than payments to retirees.

The estimate remains preliminary. Social Security calculates using the average CPI-W from July through September, comparing it to the same period in the previous year. Figures for August and September may still affect the final outcome.

CPI-W inputIndex levelRole in 2027 COLA
July 2025316.349Used as prior-year base
August 2025317.306Used as prior-year base
September 2025318.139Used as prior-year base

July 2026327.1043.1% higher than the base

An additional 3.1% rise would mean roughly $64 more each month for the projected 2026 average retired-worker benefit of $2,071. This figure is for illustration and does not represent an official 2027 benefit estimate. The average may fluctuate as new retirees start collecting benefits or if there are changes to existing payments.

The inflation picture presents more challenges for Humana. In July, the unadjusted CPI-W remained unchanged. Seasonally adjusted, medical care increased by 0.4%, and medical-care services advanced by 0.6%. Prescription-drug prices declined by 0.8%.

Humana’s Medicare Advantage premiums are not determined by Social Security benefits. Instead, these rates are based on federal payments, member risk, and medical usage. While the COLA can help household finances, it does not have a direct impact on the insurer’s profit margin.

The margin remains narrow. Humana posted a 91.2% Insurance benefit ratio for the second quarter. This resulted in 8.8 cents remaining from each premium dollar before factoring in operating expenses and other components. The midpoint for the full year, at 92.75%, leaves 7.25 cents.

Humana measureQ2 2026Q2 2025Change
Revenue$40.87 billion$32.39 billionUp 26.2%
Adjusted pretax income$1.25 billion$1.02 billionRising 22.7%
Adjusted EPS$7.61$6.27Increasing 21.4%
Adjusted Insurance operating income$824 million$770 millionAhead 7.0%
Insurance benefit ratio91.2%89.9%Higher by 1.3 points

Revenue and adjusted earnings increased at a quicker pace than operating income for Insurance. The higher benefit ratio accounts for some of the difference. This also highlights how even one month of medical inflation can have a bigger impact than the main COLA figure.

Chief Executive Jim Rechtin stated that results from the first half were “right where we said we’d be.” He attributed improved earnings to enhanced clinical care and increased efficiency. The company maintained its adjusted 2026 earnings per share forecast of at least $9.00. Humana earnings release

Humana anticipates around 25% expansion in individual Medicare Advantage membership this year, increasing scale but also heightening the financial impact of any errors in pricing or utilization.

Analysts have become more optimistic, but potential gains remain modest. MarketBeat’s compilation from 30 analysts indicates a Moderate Buy rating, with an average price target of $395.22. This figure stands just 3.3% above the price quoted on Wednesday.

Risks: Actual medical usage could surpass pricing projections. Reduced Medicare Star Ratings are already impacting 2026 profit forecasts. The ultimate COLA outcome could also significantly deviate from the initial indication given in July.

The 2027 COLA trend provides helpful context for Humana investors, though it is not the primary factor driving earnings. Key influences are benefit costs, federal payments, and the company’s ability to achieve a 25% increase in membership.

Further analysis

How does July’s CPI-W affect the outlook for the 2027 Social Security COLA?
The Consumer Price Index for Urban Wage Earners and Clerical Workers (CPI-W) in July stood at 3.1% higher than the comparison base, which is the average from the third quarter of 2025. This figure is an early estimate. The final adjustment will be determined using the average for July, August and September of 2026.
Will an increase in the Social Security COLA result in a direct boost to Humana’s revenue?
No. Social Security payouts do not determine premiums for Humana's Medicare Advantage plans. Insurer revenue depends on federal payment rates, the risk profile of members, and plan design. While an increased COLA can boost household finances, it does not directly increase Humana's profit margin.
What is the significance of the July inflation report for Humana shares?
Medical-care services increased by 0.6% in July, whereas the unadjusted CPI-W remained unchanged. Humana's insurance benefit ratio for the second quarter stood at 91.2%. As a result, higher usage or increased provider expenses could further reduce the thin underwriting margin.
Has Humana shown better results in its recent operating performance?
Second-quarter revenue climbed 26.2% to $40.87 billion. Adjusted earnings per share advanced 21.4% to $7.61. Adjusted Insurance operating profit increased 7%, while the benefit ratio deteriorated by 1.3 percentage points.
What is the primary area of uncertainty facing Humana shareholders?
The main uncertainty continues to be medical-cost execution. Humana projects around 25% growth in individual Medicare Advantage membership for 2026. While this expansion increases scale, it also intensifies potential pricing mistakes. Annual earnings are already being affected by declining Star Ratings.
What level of upside are analysts projecting at this time?
Consensus from 30 analysts rates the stock a Moderate Buy, with an average price target of $395.22. That figure is just 3.3% higher than Wednesday’s closing level of $382.52. The slim difference suggests the anticipated rebound could already be priced into the stock.
