Shares of MoviePass Inc. majority owner Helios & Matheson Analytics Inc. slumped 1.6% in premarket trade Friday, adding to the 39% plunge they have suffered the past three sessions, as investors continued to come to grips with the disclosure that its auditors had "substantial doubt" about the company's ability to continue. H&M's independent auditors had previously expressed doubt about MoviePass's ability to continue as a going concern. In the annual report filed before Tuesday's open, H&M said it had changed its primary business to the integration and development of MoviePass, and now H&M stated: "Our independent auditors have expressed substantial doubt about our ability to continue as a going concern, which may hinder our ability to obtain future financing." H&M said its ability to continue as a going concern "will be determined by out ability to obtain additional funding in the short term," which will enable it to continue to develop its MoviePass business. But the stock's losses accelerated Wednesday with a 33% plummet after H&M announced a public share offering. The stock has tumbled 68.4% over the past three months through Thursday, while the S&P 500 has lost 4.2%.
