IRVINE, CA (February 28, 2012) — BIOLASE Technology, Inc. (NASDAQ:BLTI), the World’s leading dental laser manufacturer and distributor, today announced that, based on a preliminary review of its financial performance for the fourth quarter ended December 31, 2011, the Company expects to report net revenue of approximately $13.1 million. This would represent net revenue growth of 35 percent year over year from $9.7 million in the fourth quarter of 2010. Net revenue for the fiscal year ended December 31, 2011, is expected to total approximately $48.8 million, up 86 percent year over year from $26.2 million in 2010.

Excluding equipment sales to Henry Schein, Inc. (NASDAQ:HSIC), net revenue for the fourth quarter ended December 31, 2011, is expected to total approximately $13.1 million compared to approximately $7.2 million for the fourth quarter ended December 31, 2010, an increase of approximately $5.9 million, or 82 percent.

Federico Pignatelli, Chairman and CEO, stated, “While we continue to show solid growth in the year and quarter, the Company’s fourth quarter was disappointing with an exceptionally difficult December in sales, traditionally our strongest month of the year. It appears that a particularly aggressive marketing and sales program by Henry Schein resulted in the sale of approximately 180 BIOLASE Waterlase MD™ Turbo laser systems from its inventory during the fourth quarter of 2011, with approximately 120 in the month of December alone. This likely created substantial disruption of BIOLASE’s direct sales efforts. The pending introduction of the Company’s new Waterlase MDX™ 300 and MDX 450 laser systems, recently launched at the Chicago Midwinter Dental Show on February 23, undoubtedly triggered this rushed and more determined selling effort by Schein to clear out its inventory of Waterlase MD Turbo laser systems causing intense competition that greatly confused our customers during the period.

“As announced today, however, we have entered into a definitive agreement to purchase all of the Waterlase MD Turbo laser systems remaining in Schein’s inventory, approximately 180 machines, at very favorable pricing and conditions to BIOLASE,” continued Pignatelli. “A substantial part of the purchase will be paid with monies currently owed to BIOLASE by Henry Schein, with the remainder paid in cash at closing after our inspection of the units has been completed. This new definitive agreement supersedes and terminates all previous agreements between the two companies. It is expected that the Company’s purchase of Henry Schein’s inventory of Waterlase MD Turbo laser systems will result in a substantial one-time gain from the reversal of previously accrued warranties and other items.”

Pignatelli concluded, “I am very pleased with the outcome of this new definitive agreement and I am looking forward in continuing to build BIOLASE’s sales and marketing efforts without the potential disruption from this inventory overhang, which could continue to unbalance our efforts as a direct sales operation. With a large amount of inventory in the hands of such a powerful competitor as Henry Schein, it was extremely challenging for BIOLASE to project and meet revenues in 2011. Having Henry Schein’s remaining inventory of Waterlase MD Turbo laser systems under BIOLASE’s full control will help solidify our marketing efforts and direct sales business model.”
