(c) Exhibits

Exhibit 99.1        Press Release issued by Aceto Corporation dated  May 8, 2003

ITEM 9.      Regulation FD Disclosure

     The information contained in this report is being furnished pursuant to
Item 12 under Item 9 of Form 8-K.

     On May 8, 2003, Aceto Corporation, a New York corporation (the
"Registrant") issued the attached press release that included financial
information for the third quarter of fiscal 2003. A copy of the press release is
attached as Exhibit 99.1 to this Form 8-K and is incorporated herein by
reference in its entirety.

     In addition, during the earnings conference call held by the Registrant on
May 8, 2003, the Registrant provided certain additional earnings guidance. The
Registrant stated that with respect to the first quarter of fiscal 2004 it
believes it will earn at least $.20 per diluted share without giving effect for
any new product launches. This additional earnings guidance was intended to
constitute a forward-looking statement within the meaning of Section 27A of the
Securities Act of 1933, as amended, and Section 21E of the Securities Exchange
Act of 1934, as amended. As such, it is based on current expectations, estimates
and projections made by Management and is intended to be covered by the
safe-harbor provisions for forward-looking statements. The forward-looking
statement was made as of the date hereof, and the Registrant assumes no
obligation to update it. The forward-looking statement is subject to risks and
uncertainties that could cause actual results to differ materially. These
uncertainties include, but are not limited to, economic and political conditions
in the United States and abroad, as well as other risks detailed in the
Registrant's SEC reports, which are available at WWW.SEC.GOV.


     Pursuant to the requirements of the Securities Exchange Act of 1934, the
Registrant has duly caused this Report to be signed on its behalf by the
undersigned hereunto duly authorized.
