AmpliPhi Biosciences Announces Stockholder Approval of Business Combination with C3J Therapeutics

SAN DIEGO–(BUSINESS WIRE)–AmpliPhi Biosciences Corporation (NYSE American: APHB), a
clinical-stage biotechnology company focused on precisely targeted
bacteriophage therapeutics for antibiotic-resistant infections, today
announced that its stockholders voted to approve the proposals required
to complete the business combination with C3J Therapeutics at a special
meeting of AmpliPhi Biosciences stockholders held earlier today.
Approximately 94% of the shares voted at the special stockholder meeting
voted in favor of the transaction, with each of the other related
proposals also receiving sufficient votes for approval.

“Today’s resoundingly favorable shareholder vote clearly supports our
combining of AmpliPhi and C3J Therapeutics to form a leading
biopharmaceutical company focused on developing a promising portfolio of
natural and synthetic phage therapies to treat serious and
life-threatening antibiotic-resistant infections,” said Paul C. Grint,
M.D., CEO of AmpliPhi Biosciences. “The Board and management team have
worked diligently for this result, which we believe is the best outcome
for our shareholders, and I want to thank our shareholders for their
support. I look forward to transitioning to the leadership of C3J’s
Chief Executive Officer, Todd R. Patrick, and the team of experienced
executives that will lead further development of these important drug
candidates.”

As previously announced, the Boards of Directors of both AmpliPhi and
C3J unanimously approved the business combination in January 2019. The
Board of Directors of AmpliPhi has also determined that the previously
announced reverse stock split, which is expected to be completed
immediately prior to the consummation of the business combination, will
be effected at a ratio of 1-for-14. The business combination transaction
is expected to close on Thursday, May 9th, at which time AmpliPhi and
C3J will become Armata Pharmaceuticals, Inc. The shares of the combined
company are expected to commence trading on the New York Stock Exchange
under the symbol “ARMP” on Friday, May 10, 2019.
