Exhibit 99.1 FOR IMMEDIATE RELEASE --------------------- ACETO CORPORATION ANNOUNCES THIRD QUARTER FINANCIAL RESULTS WITH EPS OF $0.11 VS. $0.08 IN LAST YEAR'S THIRD QUARTER RECEIVES EPA APPROVAL FOR ASULAM HERBICIDE LAKE SUCCESS, NY - May 5, 2006 - Aceto Corporation (NASDAQ:ACET), a global distributor of chemically-derived pharmaceuticals, biopharmaceuticals, specialty chemicals and agrochemicals, today announced results of operations for its fiscal 2006 third quarter and nine months ended March 31, 2006. Net sales for the third quarter were $80.8 million, compared to $82.5 million in the third quarter of fiscal year 2005. The Company's selling, general and administrative expenses decreased 18% from the third quarter of last year, producing a 43% increase in operating income to $4.1 million. Aceto reported net income of $2.8 million or $0.11 per diluted share, a 45% increase from $1.9 million or $0.08 per diluted share in the 2005 quarter. The 2005 quarter includes a $0.01 loss from the Company's discontinued Institutional Sanitary Supplies ("ISS") segment. For the nine months ended March 31, 2006, net sales were $225.3 million compared to $239.7 million in the same period of the prior year, attributable to the previously disclosed decrease in sales of two active pharmaceutical ingredients (APIs) due to intense competition. Net income was $6.3 million or $0.26 per diluted share in the nine-month period, compared to $7.2 million or $0.29 per diluted share in the same period of fiscal 2005. The 2006 period includes an after tax charge of $0.01 per diluted share for exiting the ISS facility, and the 2005 period includes a $0.02 loss from the Company's discontinued ISS segment. Leonard S. Schwartz, Chairman, CEO, and President of Aceto, stated, "I am pleased with our performance in the third quarter. Importantly, despite the highly competitive environment for APIs, our Health Sciences margins rose on a comparable quarter basis, and our market position for APIs is strengthening as a result of our continued focus on enhancing our regulatory capabilities and our sourcing operations in India and China. Combined, these skills enable us to grow our position in the rapidly consolidating generic pharmaceuticals market. We have also been successful in controlling SG&A costs with no diminution of our operational capabilities, while at the same time continuing to invest resources and funds in our new business initiatives. We realized additional cost savings during the quarter, and believe the SG&A level recorded in the third quarter will be our approximate run rate going forward." Providing an update on Aceto's new business initiatives, Mr. Schwartz commented, "With regard to our vaccines for companion animals, the USDA recently approved and gave high marks to the factory of our supplier. However, the USDA is requiring Aceto to perform an additional study to confirm that the testing for the vaccines completed in the EU (which was part of the basis for the supplier's EU approval and provided highly satisfactory results), is in accordance with USDA standards under 9 CFR regulations. We believe this cautionary action by the agency is a direct result of our application being the first ever companion 1 animal vaccines from any supplier outside of the U.S. This additional study extends the anticipated date of approval from late fiscal 2006 to the first half of fiscal 2007. Nevertheless, our marketing program remains on track to sell product under the Aceto label, and we plan to enter the market immediately following receipt of the license." Mr. Schwartz continued, "We are also proceeding with our initiative to sell Aceto branded generic drugs in finished dosage form directly into distribution channels. Integral to the development of this business initiative are: 1) customer acceptance of our marketing strategy, 2) regulatory compliance and 3) supply of approved generic drugs. I am pleased to say that we are progressing well on all three fronts." "As we have stated previously, regarding human generic biopharmaceuticals there is no definitive time frame for regulatory pathways in the U.S. However, we are encouraged by the movement toward regulatory action stemming from developments in the EU as well as some recent progress in the U.S. Last month, a U.S. federal judge ordered the FDA to make a decision on Omnitrope, a generic biopharmaceutical recombinant human growth hormone that was granted marketing authorization by the European Commission. If/when U.S. regulatory pathways are put in place, which would certainly help combat the continuing rise in health care costs, we would capitalize on Aceto's unique position and bring products to the U.S. market from our portfolio of 38 products, three of which are covered under our agreement with Three Rivers Pharmaceuticals." Mr. Schwartz further stated, "With respect to expanding our Agrochemicals segment, we received EPA approval of Asulam, a herbicide used on sugar cane, and will commence supply under a multi-year contract with a major agricultural chemical distributor beginning in the spring 2007 season. The Agrochemicals segment generates higher margins than our other two segments, and should become a larger contributor to our earnings next year." As relates to Aceto's Chemicals & Colorants segment, Mr. Schwartz commented, "We are very pleased with the results in our Chemicals & Colorants segment. The efforts we are putting forth in China for the development of our sourcing operations, combined with the recent acquisition of our own office space, are keeping pace with the rapid growth of the Chinese chemical industry and are bearing fruit. One illustration of this is the success we are having with organic color pigments." Mr. Schwartz concluded, "Our financial position remains extremely strong. We closed the third quarter with working capital of $101.8 million, no long-term debt and shareholders' equity of $112.4 million. We are enthusiastic about Aceto's long-term outlook based on strength in our core businesses, as well as the prospects for our new initiatives. In the fourth quarter of fiscal 2006, we expect to earn approximately $0.09 per diluted share, compared to $0.11 in the final quarter of fiscal 2005. The final quarter of 2005 included a tax benefit of $0.05 per diluted share due to a one-time reduction in the valuation allowance for a portion of Aceto's deferred tax assets in that quarter." 2 CONFERENCE CALL Leonard S.
