Core WaterLase Unit Sales Increase 29.9%, Quarter over Quarter
Core WaterLase Non-GAAP Adjusted Revenues Increase 42.0%, Year-to-Date over Prior Period

IRVINE, CA (November 5, 2012) — BIOLASE, Inc. (NASDAQ:BIOL), the world’s leading dental laser manufacturer and distributor, today reported unaudited financial results for the three- and nine-months ended September 30, 2012. Financial highlights include:

Operating highlights of and subsequent to the 2012 third quarter include:

Federico Pignatelli, Chairman and CEO, said, “Sales of our core WaterLase line of products increased by nearly 13% quarter over quarter and 20% year over year. This strong growth testifies to the successful execution of our sales and marketing strategies. While we met our revenue guidance for the third quarter, we are cautiously reducing our range of annual revenue guidance to adjust for the timing delay in obtaining regulatory clearance for our new EPIC 10 soft tissue diode laser. We received CE Mark clearance for the EPIC 10 with only 2 days remaining in the quarter and FDA approval in the fourth quarter, which limited the number of units that we could ship in the quarter.

“In addition to our top line growth, we are very pleased that the combination of improved margins and lower general and administrative expenses enabled us to generate non-GAAP net income during the quarter,” noted Pignatelli.

Third Quarter Financial Results
Net revenue for the third quarter of 2012 totaled $13.8 million, compared with $13.1 million in the third quarter of 2011. The increase of $720,000, or 5.5%, was primarily driven by increased sales of the Company’s all-tissue WaterLase systems and increased imaging revenues, partially offset by lower diode systems sales as customers anticipated the launch of the EPIC 10. The 2011 third quarter revenue included $0.9 million in sales to Schein to satisfy one-time prepaid purchase orders. Excluding these amounts, net revenue for the 2012 third quarter represents a 13.4% increase over non-GAAP adjusted net revenue of $12.2 million for the third quarter of 2011.

The number of WaterLase systems sold increased by 29.9% in the third quarter of 2012 as compared to the prior year quarter, primarily due to increased sales of the WaterLase iPlus^® systems and pre-owned WaterLase MD Turbo™ systems. Revenues from the sale of WaterLase systems increased $1.1 million, or 12.7%, to $9.3 million in the third quarter of 2012 as compared to $8.2 million in the prior year quarter. The 2011 third quarter revenue from the sale of WaterLase systems includes approximately $200,000 in sales to Schein to satisfy one-time prepaid purchase orders. Excluding this amount, revenue from the sale of WaterLase systems for the third quarter of 2012 increased by $1.2 million, or 15.2%, over non-GAAP adjusted net revenue for the prior year quarter. WaterLase system sales comprised approximately 67.2% of net revenues for the third quarter of 2012 compared to 62.9% for the prior year quarter. The majority of these WaterLase revenues were from sales of the Company’s flagship WaterLase iPlus all-tissue laser system.

Diode laser system sales comprised approximately 6.5% of net revenues for the third quarter of 2012 compared to 16.6% for the prior year quarter. Diode laser sales were impacted in the third quarter of 2012 pending regulatory clearance of the new EPIC 10 diode laser system. BIOLASE received the CE Mark for the EPIC 10 in the final days of September 2012, and received notice of its regulatory clearance from the FDA on October 1, 2012. As a result, the Company expects that diode laser system sales will increase significantly beginning with the fourth quarter of 2012.

Pignatelli added, “The EPIC 10 is an exceptional diode laser platform and an exciting new product in the field. It offers more precise cutting, improved patient comfort, and 15 pre-programmed commonly-performed soft tissue procedures, including pain therapy. We believe EPIC 10 has the potential to become a very successful soft-tissue surgical product. We have experienced tremendous interest and have generated a healthy backlog both domestically and internationally since receiving CE Mark approval and regulatory clearance from the FDA. As a result, we expect the EPIC 10 will be a strong contributor to revenue in the fourth quarter of 2012 and beyond.”

Imaging revenues totaled approximately $675,000, or 4.9% of net revenue, during the third quarter of 2012 as compared to $100,000, or 0.7% of net revenue, for the prior year period, an increase of 575%.

Gross profit as a percentage of net revenue was 45.6% as compared to 40.7% for the prior year period. The year-over-year increase for the third quarter was primarily due to increased sales of WaterLase systems, increased license fees and royalty revenue, and decreased costs of revenues as service and warranty expenses continue to decline as manufacturing processes and quality continue to improve.

Operating expenses totaled $6.7 million, or 48.4% of net sales, as compared to $6.3 million, or 47.9% of net sales, in the third quarter of 2011. The increased costs reflect the Company’s continued investment in growing its core business, as follows:

As a result, the net loss for the third quarter of 2012 was $548,000, or ($0.02) per share, compared to a net loss of $953,000, or ($0.03) per share, for the third quarter of 2011.

After removing interest expense of $98,000, non-cash depreciation and amortization expenses of $126,000, and non-cash stock-based, other equity instruments and other non-cash compensation expense of $420,000, this year’s third quarter resulted in non-GAAP net income of $96,000, or $0.00 per share, compared with a non-GAAP net loss of $397,000, or ($0.01) per share, for the third quarter of 2011.

Nine Months Financial Results
GAAP net revenue for the nine months ended September 30, 2012, totaled $38.3 million, compared with net revenue of $35.7 million in the prior year period. The 2012 nine-months revenue reflects a $1.1 million reduction related to the repurchase of WaterLase MD Turbo laser system inventory from Schein, which was completed in April 2012. The 2011 nine-month revenue includes $5.9 million in sales to Schein to satisfy one-time prepaid purchase orders. Excluding these amounts, non-GAAP adjusted net revenue for the nine months ended September 30, 2012, of $39.4 million represents a 32.2% increase over non-GAAP adjusted net revenue of $29.8 million in the prior year period.

The number of WaterLase systems sold during the nine months ended September 30, 2012, increased by 35.1% as compared to the prior year period, primarily due to increased sales of the WaterLase iPlus systems and pre-owned WaterLase MD Turbo systems. Gross revenues from the sale of WaterLase systems, excluding the $1.1 million inventory repurchase from Schein during the second quarter, increased $5.2 million, or 25.9%, to $25.4 million for the nine months ended September 30, 2012, as compared to $20.2 million in the prior year period. The 2011 nine month revenue from the sale of WaterLase systems includes $2.3 million in sales to Schein to satisfy one-time prepaid purchase orders. Excluding this amount, non-GAAP adjusted net revenue from the sale of WaterLase systems for the nine months ended September 30, 2012, increased by $7.5 million, or 42.0%, over non-GAAP adjusted net revenue for the prior year period. WaterLase system sales comprised approximately 63.5% of net revenues for the nine months ended September 30, 2012, compared to 56.6% for the prior year period. The majority of these WaterLase revenues were from sales of the Company’s flagship WaterLase iPlus all-tissue laser system.

Pignatelli commented, “While we continue to look for distribution opportunities to leverage the BIOLASE direct sales force and service engineers, our primary growth drivers for the foreseeable future will be revenue growth in our core WaterLase products and from the highly-anticipated EPIC 10. We have begun implementing several consumer-based initiatives that we believe will enhance this demand in 2013 by driving patients to laser dentists and creating more pull from the marketplace.”

Imaging revenues totaled approximately $1.7 million, or 4.5% of net revenue, during the nine months ended September 30, 2012, as compared to $100,000, or 0.3% of net revenue, for the prior year period.

Gross profit as a percentage of net revenue was 46.0% for the nine months ended September 30, 2012, as compared to 44.2% for the prior year period. The year-over-year increase was primarily due to increased sales of WaterLase systems, coupled with lower costs of revenues reflecting lower service and warranty expenses due to ongoing improvements in manufacturing processes and quality, offset by reduced diode systems sales and reduced license fees and royalty revenue.

Operating expenses totaled $21.3 million for the nine months ended September 30, 2012, or 55.7% of net sales, as compared to $17.8 million, or 50% of net sales, in the prior year period. The increased costs were primarily in sales and marketing and engineering and development, and reflect the Company’s continued investment in growing its core business.

The net loss for the nine months ended September 30, 2012, was $4.1 million, or ($0.13) per share, compared with a net loss of $2.5 million, or ($0.08) per share, in the prior year period.

After removing interest expense of $140,000, non-cash depreciation and amortization expenses of $373,000, and non-cash stock-based, other equity instruments and other non-cash compensation expense of $1.5 million, the non-GAAP net loss for the nine months ended September 30, 2012, was $2.1 million, or ($0.07) per share compared with a non-GAAP net loss of $175,000, or ($0.01) per share, for the nine months ended September 30, 2011.

Liquidity and Capital Resources
As of September 30, 2012, BIOLASE had approximately $6.2 million in working capital. Cash and cash equivalents and restricted cash totaled approximately $1.3 million at September 30, 2012, compared to $1.7 million at June 30, 2012, and $3.3 million at December 31, 2011. Accounts receivable totaled $10.3 million compared to $9.6 million at June 30, 2012, and $8.9 million at December 31, 2011. Stockholders’ equity was $10.3 million at September 30, 2012. In addition, the Company had two revolving credit facilities totaling $8.0 million, with $5.1 million of available borrowings, in excess of the $2.2 million outstanding, at September 30, 2012.

Financial Outlook
BIOLASE expects net revenue for the fourth quarter of 2012 of approximately $16.5 million to $17.5 million, which reflects expected growth of 26% to 34% as compared to the same period last year. The Company also expects to generate non-GAAP net income and be cash flow positive in the fourth quarter of 2012.

Due to the timing in obtaining regulatory clearance for our new EPIC 10 soft tissue diode laser, BIOLASE expects non-GAAP adjusted gross revenue of $55 million to $58 million for 2012, which excludes the $1.1 million reduction in net revenue from the inventory re-purchase from Schein during the 2012 second quarter. Therefore, the Company’s GAAP revenue guidance, which includes the $1.1 million reduction in net revenue from the inventory re-purchase from Schein during the 2012 second quarter, is effectively $53.9 million to $56.9 million for fiscal 2012.

Management believes that providing these non-GAAP financial measures allows investors to view the Company’s financial results in the way that management views the financial results.
