(Nasdaq: HSIC), the largest provider of healthcare products and services to office-based practitioners in the combined North American and European markets, today confirmed 2004 guidance of $3.55 - $3.61 earnings per diluted share, assuming timely receipt of orders of Fluvirin(R) influenza vaccine from Chiron Corporation (Nasdaq: CHIR). The Company is issuing this guidance in response to the press release distributed yesterday by Chiron stating that shipments and releases of Fluvirin have been delayed until early October. "While this new development shifts the timing of Fluvirin sales entirely into the fourth quarter, we continue to look forward to our 15th straight year as a reliable source of influenza vaccine for our customers," said Michael Racioppi, President of Henry Schein's Medical Group. This season, Henry Schein is expected to be the only source to obtain influenza vaccine from all three Food and Drug Administration-approved manufacturers. The Company will make available to its customers injectable vaccine for adults and children as young as six months and the nasally administered FluMist(TM) vaccine, manufactured by MedImmune (Nasdaq: MEDI). Earlier this year Henry Schein was named exclusive distributor for the FluMist product. - more -
