UnitedHealth Group ( UNH ) shares rose 5.3% in recent Tuesday trading after Q1 profit and revenue topped estimates by analysts, and the company affirmed its 2024 adjusted earnings outlook despite disruptions from a cyberattack.

Earlier Tuesday, the company reported Q1 adjusted earnings of $6.91 a share, up from $6.26 a year earlier. Analysts polled by Capital IQ expected $6.62.

Revenue in the quarter ended March 31 rose to $99.8 billion from $91.93 billion a year earlier. Analysts surveyed by Capital IQ expected $99.28 billion.

The company said it continues to expect full-year 2024 adjusted EPS of $27.50 to $28. Analysts expect $27.53.

UnitedHealth ( UNH ) said it booked $872 million in costs in Q1 due to the Change Healthcare cyberattack, which is expected to cost $1.35 billion to $1.6 billion in the year ending Dec. 31.

Chief Executive Officer Andrew Philip Witty said on an earnings call that UnitedHealth's ( UNH ) "substantial resources" helped mitigate the impact of the attack, and he vowed to "bring (Change Healthcare) back much stronger than it was before."

Without UnitedHealth Group ( UNH ) owning Change Healthcare, "this attack would likely still have happened, and it would have left Change Healthcare, I think extremely challenged to come back," Witty said.
