SAN DIEGO, April 21, 2017 /PRNewswire/ -- Mast Therapeutics, Inc. (NYSE MKT: MSTX) today announced that
the Special Meeting of Stockholders held earlier today was convened and adjourned without any business being conducted other than
the adjournment. The meeting will reconvene on Thursday, April 27, 2017 at 9:00 a.m.,
local time, at the same location, 3611 Valley Centre Drive, Suite 500, San Diego, California 92130. The record date for stockholders entitled to vote at the special meeting will remain
March 13, 2017.

The adjournment will allow for the solicitation of additional votes on the proposals contained in Mast's proxy
statement/prospectus/information statement. While the merger with Savara Inc., the reverse split, and the name change
proposals are all exceeding 90% approval based on votes cast to date, approval of more than 50% of all outstanding shares of Mast
common stock is necessary to obtain a quorum and for the merger to go forward. At the meeting, it was deemed that the
holders of a sufficient number of the Mast's outstanding common stock have not yet submitted proxies to indicate how their shares
should be voted and additional time was needed to collect the required votes.
"We are pleased with the strong support for the proposals based on the votes that have come in to date. However, more
stockholders need to participate in the special meeting for approval of the merger and the related proposals. Based on
progress to date, we believe reconvening the meeting on Thursday will provide sufficient time to obtain the necessary votes to
move forward with the merger," stated Brian M. Culley, Chief Executive Officer of Mast.
During the period of the adjournment, Mast will continue to solicit proxies from its stockholders of record as of
March 13, 2017. Mast has retained a second proxy solicitor, Alliance Advisors, to increase the outreach to a larger
number of stockholders. Stockholders who have already voted do not need to recast their votes.
As previously announced, leading independent proxy advisory firms, Institutional Shareholder Services Inc. (ISS) and Glass,
Lewis & Co., LLC (Glass Lewis) recommend that Mast stockholders vote "FOR" the merger and the related proposals. Mast's board
of directors unanimously recommends that stockholders vote "FOR" all meeting proposals.
Mast stockholders should note that the merger proposal (Proposal 1), the reverse stock split proposal (Proposal 2) and the
name change proposal (Proposal 3) must all be approved for the merger to be completed. If any of those proposals is not
approved, the merger will not go forward. Failure to vote or an abstention from voting will have the same effect as a vote
"AGAINST" the merger and related proposals. All stockholders are asked to vote "FOR" all proposals
now. If you previously voted against any of these proposals and would now like to change your vote, you can do so by
contacting Mast's proxy solicitors.
