Allion Healthcare Reports Second quarter 2008 Results

• Net sales for the quarter increased 39% to a record $86.4 million

• Net income increased 200% to $2.9 million

• Earnings per diluted share up 83% to $0.11

MELVILLE, NY — August 7, 2008 — Allion Healthcare (NASDAQ: ALLI) today announced financial results for the three months ended June 30, 2008, which include its recent expansion into the Specialty Infusion market. As a result of the April 4, 2008 acquisition of Biomed America, Inc. (“Biomed”), the Company now operates its business in two segments: Specialty HIV, which is the Company’s legacy specialty pharmacy and disease management services focused on HIV/AIDS patients, and Specialty Infusion, which is the Company’s recently acquired Biomed business of specialized biopharmaceutical medications and services to chronically ill patients. Results for the second quarter reflect the acquisition of Biomed effective April 4, 2008.

Summary of Results

Consolidated net sales for the second quarter of 2008 increased 39% to $86.4 million, compared to $62.3 million for the second quarter of 2007. Same store sales from the Company’s Specialty HIV segment increased 10% to $68.7 million principally resulting from patient growth in its California market. The number of Specialty HIV prescriptions filled increased 7% over the same period in 2007. The Biomed acquisition added $17.7 million in Specialty Infusion revenues during the second quarter of 2008. Approximately 93% of the Specialty Infusion sales were from Hemophilia patients receiving Blood Clotting Factor and patients with Auto Immune Disorders/Neuropathies receiving IVIG.

Gross profit was $17.1 million and $8.9 million for the three months ended June 30, 2008 and 2007, respectively, and represents 19.8% and 14.3% of net sales, respectively. The increase in gross profit as a percentage of revenues is primarily attributable to the relatively higher gross margins of our Specialty Infusion business compared to our Specialty HIV business. The Company’s gross margin from the Specialty HIV segment remained approximately at historical levels.

Selling, general and administrative expenses increased to $9.8 million, or 11.3% of net sales, during the second quarter of 2008, compared to $6.5 million, or 10.5% of net sales, during the second quarter of 2007. The increase was primarily due to the acquisition of the Specialty Infusion segment. The Company does not expect to realize significant cost efficiencies as a result of the Biomed acquisition.

The Company reported net income for the period of $2.9 million, a three fold increase when compared to net income of $973,000 for the second quarter of 2007.

Earnings per diluted share for the second quarter of 2008 were $0.11 compared to earnings per diluted share of $0.06 for the second quarter of 2007.

EBITDA increased to $7.3 million for the second quarter of 2008, from $2.3 million for the second quarter of 2007. An explanation and reconciliation of Net income under GAAP to EBITDA and adjusted EBITDA is provided below.

“Allion’s results for the second quarter exceeded our expectations,” commented Michael Moran, Chairman, President and Chief Executive Officer of Allion Healthcare. “We had a strong second quarter in our Specialty HIV segment, realizing double digit organic growth and steady gross margins. The Biomed acquisition is off to an excellent start and met our earnings target. We feel strongly that the acquisition of Biomed will continue to provide our stockholders with a stronger, more diversified Company and will continue to generate growth in earnings.”

The Company announced that it has established a new subsidiary called Alligenix. Alligenix will focus on relationships with Pharmaceutical manufacturers of both HIV and Specialty Pharmacy products. Bill Jones will serve as the President of Alligenix. Mr. Jones has previously served in senior positions with Medco and US Bioservices, as well as a consultant to Allion during the integration of Biomed. “We are thrilled to attract someone with Bill’s background to join Allion in this new opportunity. We have had some success in small programs working directly with Manufacturers, and believe that with our substantial data base of historical adherence data, and our ability to offer customized services for them, we will be able to generate new revenue opportunities through this division,” commented Mr. Moran.

The Company also announced today that its Board of Directors has appointed Flint D. Besecker as an independent director who will serve on the Nominating and Corporate Governance Committee and will chair the Compensation Committee. Mr. Besecker is currently principal of Firestone Asset Management, a Director with Care Investment Trust (NYSE: CRE) and most recently held the position of President, CIT Healthcare. Mr Besecker fills the vacancy created by the resignation of Harvey Werblowsky, Esq., which was effective upon the election of Mr. Besecker.

Mr. Moran stated, “We welcome Mr. Besecker to our Board of Directors. His extensive experience in the healthcare financial service sector will be an invaluable asset as we continue to broaden our products and services. I would also like to thank Harvey Werblowsky, Esq. for his dedicated service as a past member of the Allion Board.”

EBITDA refers to net income before interest, income tax expense, and depreciation and amortization. Allion considers EBITDA to be a good indication of the Company’s ability to generate cash flow in order to liquidate liabilities and reinvest in the Company. EBITDA is not a measurement of financial performance under GAAP and should not be considered a substitute for net income as a measure of performance. Adjusted EBITDA excludes the litigation settlement and expenses related to the Oris litigation, and the impairment of long-lived assets to reflect comparable year over year EBITDA performance and provide investors with supplemental information to assess recurring EBITDA performance.
