FOR IMMEDIATE RELEASE

ACETO CORPORATION ANNOUNCES 6% INCREASE IN OPERATING INCOME

COMPARED TO YEAR AGO QUARTER

LAKE SUCCESS, NY – November 9, 2007 – Aceto Corporation (NASDAQ:ACET), a global leader in the sourcing, regulatory support, marketing and distribution of chemically derived pharmaceuticals, biopharmaceuticals, specialty chemicals and crop protection products, today announced results of operations for the first fiscal quarter ended September 30, 2007.

Net sales for the first quarter were $79.5 million, an increase of 6.4% from $74.7 million in the year ago quarter.  Gross profit increased 15.9% to $14.6 million from $12.6 in the fiscal 2007 quarter. Selling, general and administrative expenses increased 17.8% to $10.8 million from $9.2 million in the fiscal 2007 quarter. Operating income increased 6.0% to $3.6 million compared to $3.4 million in the 2007 comparable quarter.  Net income decreased 47.4% to $1.3 million, or $0.05 per diluted share, down from $2.5 million or $0.10 per diluted share in the 2007 quarter. The fiscal 2008 quarter is being negatively impacted by two charges. The first charge is $0.9 million of expenses relating to an anti-trust case that Aceto has commenced against the owner of certain licensed technology used by one of Aceto’s crop protection products.  The second charge that impacted the first quarter was the devaluation of our tax deferred asset in Germany as the result of a change in the German tax rate from 40% to 30% which caused Aceto to take a non- cash charge of $1.4 million.

Leonard S. Schwartz, Chairman, CEO, and President of Aceto, stated, “We are pleased with the operating results that we have reported today.  Operating income in the first quarter of 2008 increased 6.0%, driven by the 6.4% increase in net sales and the 18.3% gross profit margin, partially offset by a 17.8% increase in selling, general and administrative expenses which was primarily the result of increased legal expenses, and expenses to support our increased marketing efforts. Had it not been for the two specific charges that negatively impacted the quarterly results, the largest of which was a non-cash expense, our net income would have been $0.13 per diluted share compared to the $0.10 reported in the fiscal 2007 first quarter.”

“I am extremely pleased to announce that we have taken another step forward with our Strategic Initiative to provide finished dosage form generic drugs by entering the market and taking an order for our first human finished dosage form generic drug, Ondansetron.  This product is used to prevent the nausea and vomiting associated with traditional cancer treatments, chemotherapy and radiation.  The product fits nicely into our business model of distributing mature products from small to mid size foreign manufacturers who have no direct access to the US markets.”

“During the first quarter of fiscal 2008 sales in our Health Sciences segment grew 9.8% from the 2007 comparable quarter, largely the result of increased sales in our domestic generics product group, as well as increased sales from our foreign subsidiaries, particularly Germany and Singapore.  Our Chemicals & Colorants sales decreased 1.9%, primarily the result of a decrease in the sales of pigment intermediates, other intermediates, and a decrease in sales of our products sold to the food and beverage industries.  These decreases were partially offset by increases in sales of our pigments products and our agricultural intermediates products.  Sales in Crop Protection increased 34.4%, primarily attributable to increased sales of our sprout inhibitor products.”

Updating the status of Aceto’s current Strategic Initiatives, Mr. Schwartz commented, “Looking at our initiative to provide vaccines for companion animals, the requisite animal challenge testing which needs to be redone under the revised testing protocol has begun. In addition, as we have previously disclosed, there will also be a requisite field safety test that will need to be completed.  At this point in time, based on our ongoing conversations with the USDA, we believe that these are the final two major steps in our path towards USDA approval.  As I have said before, please be reminded that this is a regulatory review and while we are doing everything that we can to expedite the process, there can be no assurance given as to when the approval process will be 100% completed. Our application represents the first time the USDA has been asked to approve a foreign produced vaccine for companion animals in the United States.  The USDA has therefore been extremely cautious throughout the process.  Once we receive the anticipated USDA approval, we plan to enter the market promptly with Aceto-branded product.

“In addition to our announcement regarding Ondansetron, we continue to focus our efforts on establishing relationships with other suppliers of ANDA approved products and increasing the number of products in our pipeline.  We believe there are no other distribution companies attempting to do what we are doing, attesting to our biggest competitive strength, the unique marriage of our global sourcing and regulatory capabilities.  Our primary target market, the large retail pharmacies continue to remain very interested in our new and unique business model and are working closely with us in our development activities.”

“Our initiative to enter the Japanese pharmaceutical market continues to move forward.  Aceto Japan, Inc. has been formed and to date we have commenced development activities for a number of products for multiple customers.  We are focusing our efforts on expanding our reach in Japan with respect to both customers and product offerings and we continue to be encouraged by the interest that Japanese pharmaceutical companies have shown in our business model. The key component to our Japanese strategy is the fact that we will be employing Japanese nationals as well as utilizing traditional Japanese business practices and culture at Aceto Japan.”

“With respect to our Crop Protection business, the Aceto model for growth involves partnering with distribution companies to secure entry into the marketplace and acquiring new products for distribution by the acquisition or development of intellectual property leading to an EPA label.  As you may remember, Asulam was the first successful new product launched under this business model.  We have recently entered into a joint venture agreement with a large agrochemical company to launch our second product under this same model. We believe that we will be selling the product beginning with the 2009 growing season, or perhaps sooner. ”

“As you may recall, last quarter we announced we were commencing a new activity for the Company, that is the research and development for two finished dosage form pharmaceuticals in Europe. I am pleased to report that both of the projects are going well. As this is a new activity for the Company, you will see that for the first time we have listed R&D expense as a separate item on our income statement.”

Mr. Schwartz added, “As we continue to look for ways to further globalize our business, I am announcing today that we have established a new Strategic Initiative for the Company, the globalization of our nutraceutical business.”

“In fiscal 2007, our nutraceutical business had total worldwide sales of approximately $32 million with $22 million of those sales coming from the United States.  The balance of the sales, $10 million, comes from Europe and is the result of three years of work since entering the European market in 2004. As a result of this success, and the growth potential we see in that market due to changing European attitudes toward nutritional products, we have decided to globalize this important Aceto business and at the same time, create a new European business strategy. We have created a new position in Europe, Director-European Nutraceuticals, and have engaged a person with many years of experience in this business who will be responsible for all of Europe and report directly to US corporate headquarters. This is the first time that we have established a pan European business.”

Mr. Schwartz concluded, “We ended the first quarter of fiscal 2008 with working capital of $118.3 million, no long-term bank debt and shareholders’ equity of $128.7 million.  We believe this level of working capital provides us the financial strength to move our strategic initiatives forward. We remain optimistic about the Company’s long-term business prospects, with our core businesses serving as a solid foundation for future growth.  In terms of financial guidance, we expect to earn approximately $0.07 per diluted share in the second quarter of fiscal 2008, compared to $0.07 in the second quarter of fiscal 2007.
