National Amusements - which controls a sprawling empire of popular entertainment and news brands - announced a data breach last week that affected more than 82,000 people.
An investigation found that the hackers had access to files on the company's systems between December 13 and December 15.
The information leaked includes names, financial account numbers, credit card numbers, debit card numbers and PINs.
The company did not respond to requests for comment about why it took a year to inform victims that their information had been stolen but told regulators in Maine that their investigation finished on August 23.
National Amusements is best known as the company that owns Paramount movie studio, CBS, MTV and thousands of movie theaters across the U.S., UK and Latin America.
The company did not respond to questions about whether the breach was reported to officials in the UK, which says companies need to report incidents within 72 hours.
The 82,128 people affected will be given one year of free identity protection services.
Paramount suffered a data breach in August related to the exploitation of the MOVEit file transfer software vulnerability.
After an investigation the studio discovered that names, dates of birth, Social Security numbers, driver's license numbers, passport numbers and the person's relationship to Paramount were leaked during the breach.
That incident followed an announcement in July by children's television giant Nickelodeon - which is owned by Paramount - that it was investigating an alleged breach after hackers claimed to have stolen 500 GB of data.
Screenshots of the files allegedly taken included folders on some of Nickelodeon's biggest titles, including Rugrats, Avatar: The Last Airbender, SpongeBob SquarePants, Danny Phantom, the Smurfs, Monster High and more.
It does not appear the National Amusements breach is connected to the breaches at Paramount or Nickelodeon.
Amid mounting debts, National Amusements made news this week for alleged interest in selling off Paramount and other pieces of its business to competitors.
