NEW YORK ( TheStreet) --- Energroup (ENHD.OB), a Chinese reverse-merger company, may have packed it in.The producer of pork products based in China's Liaoning province filed a form 15-12G with the Securities and Exchange Commission on Monday -- a notice of termination of the registration of its securities. Essentially, the company has pulled its stock from the over-the-counter bulletin board, where regular quarterly filings are required by the SEC. Energroup shares will now likely trade on the Pink Sheets, but according to people familiar with the stock, rumors have emerged that the company's founder and chairman, Huashan Shi, may want to remove the business from U.S. capital markets completely. Shares closed Tuesday at 57 cents, down 19%, after falling 40 cents on Monday. The stock closed at $2 on Dec. 31. The news came as a shock to some investors. Energroup offered no explanation for the move. The company couldn't immediately be reached for comment. In this vacuum of information, Energroup stock plunged by more than 72% over the last two trading sessions. >>The Shanghai Numbers: A Special Series by TheStreet on Chinese Reverse Takeover Stocks Energroup, which went public in the U.S. through a reverse merger in early 2008, was likely headed for an uplisting to one of the major exchanges, according to a source familiar with the company. A handful of heavy-hitters in the Chinese small-cap investment world were behind the stock. Halter Financial provided Shi's pork-production business with a shell company to merge into. (The public entity has retained the name of that shell, Energroup.) Pinnacle Funds, a hedge fund run by Timothy Hatler's one-time partner Barry Kitt, was the lead investor in a $17 million round of private financing not long after Energroup's reverse merger. Roth Capital, a Newport Beach, Calif.-based investment bank and underwriter of scores of stock offerings by Chinese small-cap companies, was also an early Energroup shareholder. Roth and Pinnacle have teamed up on many similar Chinese deals.
