Key Takeaways

  • MGM reported a cyberattack to regulators, suggesting the hack will have a material effect on the company.
  • Moody's said the breach could negatively effect the hotel and casino operator's credit rating.
  • A ransomware group reportedly was behind the attack, which is still disrupting company systems.

Shares of MGM Resorts International (MGM) fell after the hotel and casino operator informed the Securities and Exchange Commission (SEC) about a cybersecurity attack, suggesting it will have a material effect on the company.

Moody’s also warned the issue could impact MGM’s credit rating, saying the attack “highlights key risks” to its operations, because they have a heavy reliance on technology.

The hack has disrupted the company’s systems since Sunday. Its corporate email, hotel booking, and restaurant reservation services remain offline.

MGM indicated it is investigating, and is being assisted by external cybersecurity experts and law enforcement. The FBI acknowledged it is looking into the matter.

MGM Resort International shares have declined for three straight sessions, and they have dropped to their lowest level since early June.
