BIOLASE ANNOUNCES UNAUDITED PRELIMINARY SECOND QUARTER REVENUES
104 Percent Year-over-Year Growth; 14 Percent Growth from First Quarter;
Late Change Order and Resulting Supply Chain Delays Push $2 Million of Expected Revenues into Third
Quarter

IRVINE, CA (July 13, 2011) — BIOLASE Technology, Inc. (NASDAQ:BLTI), the World’s leading dental laser manufacturer and distributor, today announced that, based on an unaudited preliminary assessment of its financial performance for the second quarter ended June 30, 2011, the Company expects to report net revenue of approximately $12.0 million, up 104 percent from $5.9 million in the second quarter of 2010 and up 14 percent from $10.6 million in the 2011 first quarter.  Approximately $2 million of orders received in the second quarter were unable to be shipped by June 30, 2011, primarily due to the timing of a significant change order placed by Henry Schein (NASDAQ:HSIC) and the resulting last minute delays of critical components.  Excluding royalties of $375,000 and $1.1 million in the second quarter of 2011 and 2010, respectively, this represents an increase of $6.8 million, or 142 percent, period over period. 

Federico Pignatelli, Chairman and CEO, said, “Commercial activities during the quarter were on track with our quarterly and annual forecasts.  However, primarily due to the timing of a significant change from Schein on a prepaid purchase order, which occurred well into the quarter, we were unfortunately unable to obtain certain critical components in time to ship a portion of such order by June 30, 2011.  We view this as a timing issue and our overall expectations for the Company in 2011 remain unchanged.”

BIOLASE originally planned its second quarter production and organized its supply chain accordingly, anticipating that it would continue to produce iLase™ systems in order to fulfill the final $3 million of the $9 million of purchase orders from Schein with the iLase system.  This prepaid purchase order gives Schein certain rights and priority of delivery.  Some critical components have long lead times and require orders to be placed months in advance.  Schein informed the Company that it was changing its order from iLase systems to a combination of the Waterlase iPlus™ and, to a lesser extent, the ezlase™, on April 28, 2011, well after the start of the second quarter.

Pignatelli added, “The change in the purchase order was within Schein’s contractual rights, but it came a month into the quarter and created a considerable amount of stress on our supply chain and unfortunately a certain number of critical components did not arrive in time to allow the shipment of product by the end of the quarter.  We expect to ship the final portion by the end of July, well before the contractual due date of August 25, 2011. 

“Orders for the iPlus remain strong and the Company is experiencing a substantial increase in its adoption by new users of the Waterlase technology,” Pignatelli concluded.

Fred Furry, CFO, said, “The supply chain issues that developed due to the financial condition of the Company in 2010 are still affecting BIOLASE, but we are rapidly making progress.  We are assessing our vendor relationships, identifying alternative sources and, when appropriate, acquiring safety stock for our specialty and critical components.  We also hired Richard Whipp as our Director of Operations on July 1, 2011, and believe that his experience with lean manufacturing and supply chain management will make an immediate positive impact on our supply chain and production flow.”

The Company will provide additional details as well as an update on the positive initiatives for the second half of the year on a quarterly conference call and webcast when it reports full financial results in August.
