Humana Revises Earnings Guidance

LOUISVILLE, KY (March 12, 2008) – Humana Inc. (NYSE: HUM) today announced that the company has revised its guidance for diluted earnings per common share (EPS) for the first quarter of 2008 (1Q08) and for the year ending December 31, 2008 (FY08). The revised guidance is the result of updated projections for the company’s FY08 stand-alone PDP financial performance. The company’s Medicare Advantage, Commercial and Military services businesses are not affected by this revision in earnings guidance.

Humana now anticipates EPS for 1Q08 in the range of $0.44 to $0.46 versus its previous guidance of $0.80 to $0.85 with EPS for FY08 now projected to be in the range of $4.00 to $4.25 compared to previous guidance of $5.35 to $5.55.

The company’s revised projections for its stand-alone PDPs’ financial performance are based upon analysis of pharmacy claims through February 2008. Higher-than-anticipated claims volumes for the stand-alone PDPs year to date are reflective of a combination of factors including:

• Enhanced Plan actuarial assumptions versus experience,

• Enhanced Plan new member experience, and

• Standard Plan member mix.
