June 29th 2017

SYDNEY, Australia, June 29, 2017 (GLOBE NEWSWIRE) -- Prima BioMed Ltd (ASX:PRR) (NASDAQ:PBMD) (“Prima” or the “Company”) today announced it has entered into a securities purchase agreement with certain accredited investors to purchase 2,631,268 of its American Depositary Shares (“ADSs”) at a purchase price per ADS of US$1.90 in a registered direct offering, for total gross proceeds of approximately US$5.0 million.

In a concurrent private placement, the Company has agreed to issue unregistered warrants to purchase up to 1,973,451 of its ADSs. The warrants have an exercise price of US$2.50 per ADS, are exercisable immediately and will expire 5.5 years from the date of issuance.

Maxim Group LLC is acting as the sole placement agent for the offering.

The registered direct offering and concurrent private placement are expected to close on or about July 5, 2017, subject to the satisfaction of customary closing conditions. No Prima shareholder approval is required for the proposed allotments under the securities purchase agreement.

Prima intends to use the net proceeds from this offering to continue ongoing clinical development of IMP321 (e.g., the AIPAC and TACTI-mel studies), to continue preclinical research on IMP761, and for other general corporate purposes. A portion of the net proceeds may also be used to acquire or invest in businesses, products and technologies that Prima views as complementary to its own.

The sale of ADSs described above is being made in the U.S. to U.S. investors pursuant to a shelf registration statement on form F-3 (File No. 333-211702), as amended and previously filed with the Securities and Exchange Commission (the “SEC”) on May 27, 2016 and declared effective on June 17, 2016.
