$PPHM and SW Investment Additional Nomination to Board of Peregrine Pharmaceuticals

Biotech Industry Veteran James (Jamie) J. Egan Joins Slate of Four Highly Qualified Candidates for Election at Upcoming 2017 Annual Meeting Ronin Calls on Peregrine to Hold 2017 Annual Meeting without Further Delay

CHICAGO, Oct. 10, 2017 — Ronin Trading, LLC and SW Investment Management LLC (together with the other participants in their solicitation, “Ronin” or “we”), collectively the second largest stockholder of Peregrine Pharmaceuticals, Inc. (“Peregrine” or the “Company”) (NASDAQ:PPHM), with aggregate beneficial ownership of approximately 8.9% of the Company’s outstanding shares of common stock, today issued the following statement with respect to Peregrine.

We are excited to announce our additional nomination of James (Jamie) J. Egan, a 30-year biotech veteran, for election to Peregrine’s Board of Directors (the “Board”) at the Company’s 2017 annual meeting of stockholders (the “2017 Annual Meeting”). We believe Mr. Egan’s deep understanding of antibodies, history of senior operations roles at reputable companies in the biotech industry, and proven ability to execute large deals with major pharmaceutical firms make him ideally suited for the Board and a great complement to our previously announced slate of nominees (Gregory P. Sargen, Brian W. Scanlan and Saiid Zarrabian). Mr. Egan’s qualifications are discussed in greater detail below.

Ronin has put forth a slate of highly qualified candidates that we believe are capable of delivering stockholder value. Therefore, we are extremely frustrated that the Board continues to needlessly delay the 2017 Annual Meeting, an action that we believe benefits insiders at the expense of stockholders. It has been over ten weeks since Peregrine announced its intention to expand the size of the Board “from four to up to seven members through the addition of new highly-qualified independent directors,” yet incredibly, the Board still has not announced a single independent candidate for its slate of nominees. Stockholders should not be punished for the Board’s inability to identify qualified independent directors. Furthermore, we are dismayed that Peregrine’s first new director candidate, Dr. Roger Lias, is a Company insider rather than an independent member. Not only is it inappropriate for two Company insiders to serve on the Board, but this appointment directly contradicts Peregrine’s own statement about adding “independent” directors. We feel these actions are yet more evidence of the extraordinarily poor corporate governance practices at the Company and highlight the need for an overhaul of Peregrine’s leadership.

Considering that Peregrine’s past 15 annual meetings were held in October, it is blatantly obvious to us that the Company is stalling as a means to entrench the incumbents and insulate them from the will of Peregrine’s stockholders. To the extent the Company fails to promptly call the 2017 Annual Meeting, we intend to file suit in accordance with Delaware law to compel the holding of the meeting so we can continue this process of change.

James J. Egan (“Jamie”) currently serves as a strategic advisor to Numab AG, a Swiss biotech company that develops antibody-based therapeutics. From 2009 – 2012, Jamie was the Chief Operating Officer of Sucampo Pharmaceuticals, Inc., a publicly-traded global pharmaceutical company, during which time he worked closely with the company’s manufacturing partners. Prior to that, Mr. Egan served as Chief Business Officer of ESBATech AG, a privately held Swiss biotechnology company, from 2006 until its acquisition by Alcon S.A. for $589 million in 2009, which Mr. Egan facilitated. From 2001 – 2006, Jamie was Senior VP of Licensing and Corporate Development for biopharmaceutical company Idenix Pharmaceuticals, Inc. (“Idenix”), where he played an instrumental role in Novartis AG’s $255 million investment in the company as part of a strategic alliance that allowed Idenix to go public in 2004. Idenix was later acquired by Merck & Co. in 2014 for nearly $3.9 billion. Mr. Egan has also held senior operations roles at pharmaceutical company G.D. Searle & Co. and global healthcare company Abbott Laboratories in the 1980’s and 1990’s. Prior to becoming a biotech executive, Mr. Egan was a foreign services officer at the US embassy in Tokyo and an attorney with the Department of Justice. Mr. Egan is fluent in Japanese.
