Shares of MoviePass Inc. majority owner Helios & Matheson Analytics Inc. plummeted 34% in premarket trade Thursday, extending earlier losses, after the company announced the pricing of its $30 million public share offering. The company, which owns 92% of movie-theater subscription service MoviePass, said it sold 10.5 million "Series A-2 units" for $2.75 per unit. The units consist of one share of common stock and warrants to buy common shares. That price was 28% below Wednesday's stock closing price of $3.83. The common shares being sold, before the warrants are exercised, would increase the shares outstanding by 20%. The company said it may use the proceeds from the offering to increase its stake in MoviePass, support MoviePass operations, to satisfy amounts payable in connection with previously issued convertible notes and/or for general corporate purposes. The stock had already plunged 52.6% over the past three months through Wednesday, while the S&P 500 had slipped 3.6%.
