Shares of movie-theater operators fell in premarket trading Friday, after the Wall Street Journal reported that U.K. cinema chain Cineworld Group PLC /zigman2/quotes/206525056/delayed UK:CINE -0.53% , the parent of Regal Entertainment Group, was preparing to file for bankruptcy. The report follows Cineworld's disclosure earlier this week that it was evaluating options for additional liquidity and a balance-sheet restructuring. Cineworld's U.K.-listed shares plunged 22.5%. Shares of AMC Entertainment Holdings Inc. /zigman2/quotes/200235402/composite AMC +1.94% dropped 8.6% ahead of Friday's open, but they may also be weighed down by weakness in other so-called meme stocks. Also, Cinemark Holdings Inc. shares /zigman2/quotes/200040530/composite CNK +3.34% shed 3% premarket and IMAX Corp.'s stock /zigman2/quotes/205456197/composite IMAX +0.53% fell 0.3%. Separately, EPR Properties stock /zigman2/quotes/206791795/composite EPR +1.76% dropped 3.4% premarket, as the real-estate investment trust (REIT) has exposure to Cineworld, since Cineworld is the parent of entities that lease EPR's Regal theaters. Earlier this week, EPR said Regal was current on all payments due EPR.
