IRVINE, CA (March 5, 2014) — BIOLASE, Inc. (NASDAQ:BIOL), the world’s leading manufacturer and distributor of dental lasers, including the Company’s proprietary WaterLase^®, and a pioneer in laser surgery in other medical specialties, as well as a distributor of digital radiography, intra oral scanners, and chair-side milling machines and 3-D printers for dentistry, today reported unaudited financial results for the fourth quarter and year ended December 31, 2013.

Financial Highlights for the Fourth Quarter and Year ended December 31, 2013:

Operating Highlights of the 2013 Fourth Quarter:

Clinical and Regulatory Highlights of the 2013 Fourth Quarter:

Highlights Subsequent to the 2013 Fourth Quarter:

Net revenue for the 2013 fourth quarter totaled $15.2 million, compared with $19.1 million in the 2012 fourth quarter, a decrease of approximately $3.8 million, or 20%. Net revenue for the year ended December 31, 2013, totaled $56.4 million, a decrease of approximately $1.0 million, or 2%, as compared with net revenue of $57.4 million for the year ended December 31, 2012. The decrease in period-over-period net revenue resulted from decreases in domestic laser system revenue, offset by increases in imaging systems, consumables and other, services, and license fees and royalty revenue. We believe that these results were primarily due to our transition from primarily selling WaterLase dental lasers to selling a wide range of hard- and soft-tissue dental and medical lasers and other high-tech solutions for dentists, including digital radiography and CAD/CAM intra-oral scanners.

Federico Pignatelli, Chairman and CEO, said, “We have invested a significant amount of capital in the last year in order to significantly expand our product offerings and become the only Total Technology Solution™ provider in dentistry. As such, we currently offer several variations of our flagship WaterLase system, including the revolutionary iPlus™, the WaterLase MDX™, and the MD Turbo™; two soft-tissue diode lasers, including the EPIC™ and iLase™; a number of NewTom™ 2-D and 3-D CBCT digital radiography products; several versions of Trios^® intra-oral scanners; our newly introduced GALAXY BioMill chair-side milling machine; and a number of Stratasys^® Design Series 3-D printers. To my knowledge, no other company currently offers such a comprehensive suite of high-tech products for dentistry.

“While we expect this strategic shift to provide significant benefits in the future, it was a substantial drain on our resources for the year ended December 31, 2013. We believe that these efforts were fundamental for our future growth, however, and that we are now poised to grow into an industry leading high-tech, multi-product manufacturer and distributor. Now that we have completed our strategic reorganization to build a platform on which we can leverage our Total Technology Solution for long-term growth, our number one goal for fiscal 2014, to which we are highly committed, is to resume revenue growth and bring BIOLASE to profitability.

“Spearheading this effort is Brian Jaffe, our new Vice President, North American Sales and Marketing. Under Mr. Jaffe’s leadership we have added 15 new sales personnel since October 2013, of which 12 will be primarily focused on selling our core laser products, and have begun to reallocate and rationalize certain marketing and advertising activities. We expect that we will begin to realize the impact of these actions in the second quarter of 2014.

“Additionally, our Board has engaged Piper Jaffray to act as the Company’s exclusive financial advisor in the evaluation of strategic alternatives, including exploring possible M&A transactions with the goal of maximizing shareholder value. We have more opportunities in a variety of medical fields than we can pursue on our own. There can be no assurance, however, that any transaction will occur, or on what terms or as to the timing.

“Lastly, given the unsatisfactory results of the business for the year ended December 31, 2013, I have declined any Board-proposed option compensation for the year ending December 31, 2013. I will also remain at my symbolic $1 annual salary for the year ending December 31, 2014,” concluded Pignatelli.

For the year ended December 31, 2013, laser system net revenue decreased by approximately $3.6 million, or 9%, as compared to the year ended December 31, 2012.

Fred Furry, CFO, commented, “We believe that our overall results for the year ended December 31, 2013 cloud, to some extent, the positive changes we experienced in the fourth quarter of 2013 as we implemented changes in our sales and marketing efforts. Our net revenue of $15.2 million for the fourth quarter ended December 31, 2013, was actually our second strongest revenue quarter since the termination of our previous exclusive global distribution arrangement with Henry Schein in August 2010, and a 23% increase as compared to net revenues of $12.3 million for the third quarter ended September 30, 2013.”

Imaging revenues, which included both cone beam digital imaging and CAD/CAM intraoral scanners for the year ended December 31, 2013, increased by approximately $1.3 million, or 38%, as compared to the prior year. The growth was driven by increased offerings at various value propositions. We expect continued improvement in sales of our imaging systems during the year ending December 31, 2014, as we continue to hire more imaging-specific salespeople and gain more experience marketing and supporting these products.

Consumables and other net revenue, which includes consumable products such as disposable tips, increased by approximately 8% for the year ended December 31, 2013 as compared to the prior year. This increase in consumables and other net revenue was primarily a result of auxiliary sales to our growing laser customer base.

Services net revenue, which consists of extended warranty service contracts, advanced training programs, and other services, increased by approximately $836,000, or 15%, for the year ended December 31, 2013, as compared to the prior year. The increased revenue was due largely to increased follow-on sales related to our growing laser customer base and increased sales and marketing efforts in this part of our business.

Gross profit as a percentage of net revenue was 38% for the year ended December 31, 2013 as compared to 46% for the prior year. The year-over-year decrease is primarily due to higher sales of licensed imaging equipment, which generally carry lower margins than our laser products, and increased international laser sales, which generally carry a lower margin than our domestic laser sales.

Operating expenses totaled $32.5 million, or 58% of net revenue for the year ended December 31, 2013, as compared to $29.0 million, or 51% of net revenue, in the prior year. The year-over-year increases were primarily driven by a substantial investment in our sales and marketing efforts during 2013, legal expenses related to enforcing and protecting our intellectual property portfolio and class action lawsuits, and increases to our payroll and consulting related expenses.

Effective for sales beginning January 1, 2013, the Patient Protection and Affordable Care Act imposed a 2.3% medical device excise tax on certain product sales to customers located in the U.S. As a result, we incurred excise tax expenses of $438,000, or 1% of net revenue, for the year ended December 31, 2013.

Our net loss for the fourth quarter ended December 31, 2013, totaled approximately $2.2 million, or a loss of $0.06 per share, compared to net income of $1 million, or income of $0.03 per share, for the same prior year quarter. After removing interest expense of $214,000, our income tax provision of $18,000, depreciation and amortization expenses of $162,000, and stock-based, other equity instruments, and other non-cash compensation expense of $475,000, the fourth quarter ended December 31, 2013, resulted in a non-GAAP net loss of $1.4 million, or a loss of $0.04 per share, compared with non-GAAP net income of $1.7 million, or income of $0.05 per share, for the same prior year quarter.

For the year ended December 31, 2013, our net loss totaled approximately $11.5 million, or a loss of $0.35 per share, as compared to a net loss of $3.1 million, or a loss of $0.10 per share, for the year ended December 31, 2012. After removing interest expense of $600,000, depreciation and amortization expenses of $601,000, and stock-based, other equity instruments, and other non-cash compensation expense of $2.0 million, and adding back an income tax benefit of $164,000, the year ended December 31, 2013, resulted in a non-GAAP net loss of $8.5 million, or a loss of $0.26 per share, compared with a non-GAAP net loss of $320,000, or a loss of $0.01 per share, for the year ended December 31, 2012.

Liquidity and Capital Resources
As of December 31, 2013, BIOLASE had approximately $3.9 million in working capital. Cash and cash equivalents totaled approximately $1.4 million at December 31, 2013, compared to $2.5 million at December 31, 2012.

On February 10, 2014, we entered into a subscription agreement with Oracle Partners L.P., Oracle Institutional Partners, L.P., and Oracle Ten Fund Master L.P. under which the Company offered an aggregate of 1,945,525 unregistered shares of common stock in a private placement at a price of $2.57 per share. Gross proceeds from the sale totaled $5 million and net proceeds, after offering expenses of approximately $208,000, totaled approximately $4.8 million.
