LAS VEGAS, March 14, 2013

LAS VEGAS, March 14, 2013 /PRNewswire/ -- American Pacific Corporation
(NASDAQ: APFC) announced that in conjunction with the Company's 2013 Annual
Meeting of Stockholders, John R. Gibson has stepped down from the position of
Chairman of the Board of Directors. He was re-elected for another three year
term as a director.

Dr. Joseph Carleone, AMPAC's President and Chief Executive Officer, was
elected to succeed Mr. Gibson as Chairman, and to continue as President and
Chief Executive Officer of the Company.

These actions were taken consistent with the Company's established succession

Mr. Gibson stated, "Thoughtful and orderly succession is crucial to the
long-term health of any company. Therefore, over the past several years,
AMPAC has implemented transitions in senior management, beginning in 2009 when
I retired as CEO, and the Board named Joe Carleone as CEO. That was a wise
choice, as Joe's success in that role has demonstrated."

As part of the transition process, the Board asked Mr. Gibson to continue for
a time as non-executive Chairman, to support management and to provide
continuity for the Board. "These past three years during which I have served
as non-executive Chairman have, I hope, helped make that transition as
productive as possible," Mr. Gibson said. "Now," he continued, "with the
election of Joe Carleone as Chairman, the transition is complete."

Dr. Carleone praised Mr. Gibson for his sixteen years of exemplary executive
leadership, and his twenty-five years of dedicated service as a Director. He
observed: "During John's tenure as President, Chief Executive Officer and
Chairman, he managed AMPAC through daunting challenges in its specialty
chemicals business, led the strategic diversification of the Corporation into
two major new areas, fine chemicals and in-space propulsion, and supported the
crucial divestiture of the in-space propulsion business with considerable
benefit to stockholders." Dr. Carleone added that "the Board is delighted
that Mr. Gibson will remain a colleague as a director, and AMPAC will continue
to benefit from his experience and wisdom."

Mr. Gibson said, "Joe has demonstrated outstanding executive skills,
experience and special awareness of AMPAC and its businesses. He has earned
the leadership of AMPAC. I am positive that he will lead AMPAC to continued
