PRIORITY HEALTHCARE ANNOUNCES SECOND QUARTER RESULTS – RECORD QUARTERLY SALES

Lake Mary, FL, July 29, 2005 – Priority Healthcare Corporation (Nasdaq: PHCC) reported results for the second quarter ended July 2, 2005.

For the second quarter, sales increased 29% to $567 million, compared to the second quarter of 2004. Excluding transaction costs, net earnings were $11.8 million and diluted earnings per share were $.27. Including transaction costs, net earnings were $11.4 million and diluted earnings per share were $.26. Transaction costs associated with the Company’s pending acquisition by Express Scripts, Inc. (Nasdaq: ESRX) and another transaction that was not consummated were $575,000, or $.01, per diluted share.

“This is an exciting time in the history of Priority Healthcare. Our recently announced transaction with Express Scripts will strengthen and broaden the specialty offering for both companies to maximize the tremendous opportunities on the horizon in our industry,” stated Steve Cosler, President and Chief Executive Officer.

Mr. Cosler continued, “We are pleased with our record sales for the second quarter and the progress we have made with many of our new initiatives. Our strong sales performance was led by ophthalmology, nephrology, ambulatory surgery, primary care and the start-up of the Aetna Specialty Pharmacy.”

“Our new initiatives should be strong future contributors to our performance. We are very pleased with the response we have received to our new relationship with Serono in infertility and believe it will be a key impetus to new marketshare growth in that disease state. The Aetna Specialty Pharmacy is progressing with the exception of products that are either in short supply or not available due to exclusivity agreements with other providers. Our integration of Spectracare into our Integrity Healthcare specialty infusion platform is going well and should be completed in the third quarter. Finally, our new logistics service center in Columbus, OH is performing very well for our initial customer and we look forward to pursuing other opportunities to leverage our infrastructure.”

In commenting on certain financial aspects of the quarter, Steve Saft, Chief Financial Officer, stated, “Our 29% sales increase for the quarter was driven by 23% organic sales growth. Our gross profit increased 10 basis points to 11.1%, sequentially, from the first quarter. SG&A expense, which excludes transaction costs, decreased by 20 basis points to 7.2%, sequentially, from the first quarter, primarily driven by the ramp up of the Aetna Specialty Pharmacy.”

Mr. Saft continued, “Our balance sheet remains strong with $26 million in cash and marketable securities, offset by $70 million drawn on our line of credit. During the quarter we invested $22 million in the acquisition of Spectracare and $7 million to fund additional working capital for the Aetna Specialty Pharmacy. Cash flow from operations was a use of cash of $18 million for the second quarter. This was driven by additional working capital used in the start up of the Aetna Specialty Pharmacy, a temporary growth in inventory of $13 million and the increase in accounts receivable driven by strong growth in specialty distribution and specialty infusion, which was accelerated by the acquisition of Spectracare during the second quarter. Our trade DSO’s were 45 days, a decrease of

one day from the first quarter. Our inventory turns were 15, in line with the first quarter. Return on committed capital and invested capital for the quarter were strong at 30% and 18%, respectively, which we believe is among the highest in the industry.”

Mr. Cosler concluded, “We continue to have success with limited distribution products. We are pleased to have been selected by Bayer as one of the limited network specialty pharmacies that will distribute Viadur^®. Viadur is indicated in the palliative treatment of advanced prostate cancer. We have now added seven limited distribution products this year and are on track to achieve our goal of 10 for 2005. Along with our new initiatives, these new products are a strong foundation for our future growth.”

The costs and charges included in the above non-GAAP measures that are discussed in the press release were outside the normal course of company operations. The non-GAAP measures are used by management in assessing the Company’s on-going performance because the costs and charges were not a component of recurring operations. Management also believes investors will have a better understanding of the ongoing business if the results of operations are presented without the costs and charges. Thus, we have included a separate presentation of the results.
