MGM Resorts International could be losing between $4.2 million and $8.4 million in daily revenue and around $1 million in cash flow every day it’s under a cyberattack, a gaming industry analyst said in a Sunday report to investors.

David Katz, an equity analyst with New York-based Jefferies Group, in a weekly report on gaming, lodging and leisure companies, updated his Thursday assessments of MGM and Caesars Entertainment Inc. that included an estimate that MGM could take a 10 percent to 20 percent hit on revenue and cash flow “for the days that the current conditions exist.”
