Organization And Business Description
ORGANIZATION AND BUSINESS DESCRIPTION	Organization – In this Annual Report, “Peregrine,” “Company,” “we,” “us,” and “our,” refer to Peregrine Pharmaceuticals, Inc., and our wholly-owned subsidiary, Avid Bioservices, Inc. (“Avid”). Peregrine was incorporated under the laws of the state of California in June 1981, reincorporated in Delaware in September 1996 and commenced operations of Avid in January 2002. Business Description – We are a biopharmaceutical company committed to improving the lives of patients by manufacturing pharmaceutical products through, Avid, our contract development and manufacturing organization (“CDMO”) and through advancing and licensing our novel, development-stage immunotherapy product. Reverse Stock Split – On July 7, 2017, we effected a reverse stock split of our outstanding shares of common stock at a ratio of one-for-seven pursuant to our filed Certificate of Amendment to our Certificate of Incorporation with the Secretary of State of the State of Delaware. The reverse stock split took effect with the opening of trading on July 10, 2017. The primary purpose of the reverse stock split, which was approved by our stockholders at our 2016 Annual Meeting on October 13, 2016, was to enable us to regain compliance with the $1.00 minimum bid price requirement for continued listing on The NASDAQ Capital Market. Pursuant to the reverse stock split, every seven shares of our issued and outstanding shares of common stock were automatically combined into one issued and outstanding share of common stock, without any change in the par value per share of our common stock. All share and per share amounts of our common stock included in the accompanying consolidated financial statements have been retrospectively adjusted to give effect to the reverse stock split for all periods presented, including reclassifying an amount equal to the reduction in par value to additional paid-in capital. No fractional shares were issued in connection with the reverse stock split. Any fractional share of common stock created by the reverse stock split was rounded up to the nearest whole share. The number of authorized shares of our common stock remained unchanged. The reverse stock split affected all issued and outstanding shares of our common stock, as well as the shares of common stock underlying our stock options, employee stock purchase plan, warrants and the general conversion right with respect to our 10.50% Series E Convertible Preferred Stock (the “Series E Preferred Stock”).
