The massive ransomware attack at UnitedHealth Group is projected to cost the company a staggering $2.3 billion to $2.5 billion. 

The health insurance provider mentioned the estimate in a second-quarter earnings report on Tuesday. The $2 billion cost estimate is based on the millions UnitedHealth has already forked over to restore its systems from the attack, which caused a major outage in February.

The ensuing disruption also prevented UnitedHealth from processing medical prescriptions, which contributed to a drop in revenue, the company said in the earnings report. 

In Q1, UnitedHealth originally estimated the ransomware attack would cost it between $1 billion to $1.2 billion. But in Tuesday’s earnings report, the company’s projections soared to over $2 billion, citing the need to pay “financial support initiatives and consumer notification costs,” which include offering loans and funding to affected hospitals and pharmacies.

In the second quarter alone, UnitedHealth also experienced “$1.1 billion in unfavorable cyberattack effects,” the company added. 

The costs underscore the financial toll a major ransomware attack can have on a company—even when the ransom is paid. In UnitedHealth’s case, the company transferred over $22 million to the attackers, who also stole sensitive personal information on millions of Americans. But in April, a second ransomware gang claimed it was actually behind the attack and demanded the insurance provider pay up again. 

UnitedHealth also continues to recover from the ransomware attack, although a “majority” of the company’s IT systems have been restored. In addition, several class-action lawsuits have been filed against UnitedHealth for failing to protect patient data. As a result, the ransomware attack's costs to the company could continue to balloon.

My Experience

I've been a journalist for over 15 years. I got my start as a schools and cities reporter in Kansas City and joined PCMag in 2017, where I cover satellite internet services, cybersecurity, PC hardware, and more. I'm currently based in San Francisco, but previously spent over five years in China, covering the country's technology sector.

Since 2020, I've covered the launch and explosive growth of SpaceX's Starlink satellite internet service, writing 600+ stories on availability and feature launches, but also the regulatory battles over the expansion of satellite constellations, fights with rival providers like AST SpaceMobile and Amazon, and the effort to expand into satellite-based mobile service. I've combed through FCC filings for the latest news and driven to remote corners of California to test Starlink's cellular service.

I also cover cyber threats, from ransomware gangs to the emergence of AI-based malware. In 2024 and 2025, the FTC forced Avast to pay consumers $16.5 million for secretly harvesting and selling their personal information to third-party clients, as revealed in my joint investigation with Motherboard.

I also cover the PC graphics card market. Pandemic-era shortages led me to camp out in front of a Best Buy to get an RTX 3000. I'm now following how the AI-driven memory shortage is impacting the entire consumer electronics market. I'm always eager to learn more, so please jump in the comments with feedback and send me tips.

The Best Tech I've Had:

  • My first video game console: a Nintendo Famicom
  • I loved my Sega Saturn despite PlayStation's popularity.
  • The iPod Video I received as a gift in college
  • Xbox 360 FTW
  • The Galaxy Nexus was the first smartphone I was proud to own.
  • The PC desktop I built in 2013, which still works to this day.
