MGM Resorts International is projected to lose up to $8.4 million in revenue every day until it fixes cybersecurity issues that affected its reservation system and casino floors in multiple states.   

According to a research note from Jefferies gaming industry analyst David Katz, the company, which fell victim to a cyberattack last week, is projected to face a near-term loss between 10% and 20% in revenue and cash flow "for the days that the current conditions exist." 

According to Jefferies analysts, MGM generates about $42 million in daily revenue and $8 million in daily cash flow across the entire company. 

It's been a week since MGM announced it was targeted by a hacker which affected the company's systems earlier. 

"Promptly after detecting the issue, we began an investigation with assistance from leading external cybersecurity experts," MGM said in a statement last week. "We also notified law enforcement and are taking steps to protect our systems and data, including shutting down certain systems."

The incident affected reservations and casino floors in multiple states, including Nevada, according to The Associated Press.

The company posted on X, formerly known as Twitter, that the investigation is still ongoing, although it is working "diligently" to solve the cyber issue while addressing "individual guest needs promptly." 

Caesars Entertainment confirmed Thursday that a hacker infiltrated its computer system and stole customer data in a recent cyber attack. 

In a regulatory filing, Caesars Entertainment confirmed that it incurred, and may continue to incur, certain expenses related to this attack.

The company reportedly paid tens of millions of dollars to keep the hackers from releasing the company's data, sources familiar with the matter told Bloomberg.
