Issued broad new patent for treating eye conditions, including Presbyopia, Cataracts, and Glaucoma; provides additional support for ophthalmic applications.

•

Collected 24 new articles regarding our WaterLase^® technology published in the English language during the 2013 first quarter.

Federico Pignatelli, Chairman and CEO, said, “While our overall revenue growth was slightly above the midpoint of our guidance, it is to be noted that certain domestic product revenues generated from our WCLI Super Symposium held March 21-24 were not recognized until after the close of the first quarter. The 2013 first quarter was also heavily geared toward international revenues as a result of the AEEDC Dubai held in February and the bi-annual International Dental Show held in early March. Our international revenues have grown as a result of these efforts and BIOLASE^® now has distributors in 71 countries around the world. We are confident that these efforts will continue to increase our international business throughout 2013 and beyond.”

“Domestically we focused on expanding our efforts as the premier total technology provider in dentistry by intensifying our efforts in selling digital imaging and CAD/CAM intra oral scanners, which is evidenced by the 619% growth for our imaging revenues quarter over quarter. Our Total Technology Solution^® is a key component in our strategy to push forward the adoption of lasers as high-tech dentistry and lasers become the standard of care in dentistry versus traditional conventional methods, along with leveraging our significant installed base of diode lasers. We believe that BIOLASE is the only company in North America that currently provides a full line of high-tech products, which includes a full range of all-tissue lasers and diode soft-tissue laser products; CBCT digital imaging products; and CAD/CAM intraoral scanners. We are pleased with the level of laser sales so far this year and we expect the aggressive marketing efforts we undertook in the first quarter to begin to pay off further as we move forward in the second quarter and the rest of 2013.” continued Pignatelli.

First Quarter Financial Results
Net revenue for the 2013 first quarter totaled $14.6 million, compared with $12.3 million in the 2012 first quarter. The increase of $2.3 million, or 19%, was driven by increased sales of the Company’s core laser systems and imaging products.

Laser system net revenue increased by approximately $814,000, or 9% in the 2013 first quarter as compared to the prior year quarter.

Fred Furry, CFO and COO said, “We are very pleased that the Company obtained FDA clearance for the EPIC soft-tissue diode laser platform for over 80 indications in 19 additional medical markets in April 2013. We expect that the EPIC 10 platform will continue to be a strong contributor to revenue in the second quarter and beyond. It is gratifying to have obtained this clearance so quickly.”

Imaging revenues, which included both cone beam and CAD/CAM, totaled approximately $1.0 million, or 7% of net revenue, during the 2013 first quarter as compared to $143,000, or 1% of net revenue, for the prior year quarter.

Pignatelli commented, “We added cone beam digital imaging to our product offerings in late 2011, and further expanded our imaging product offerings with the addition of CAD/CAM intra-oral scanning in late 2012. It is promising to see these product lines continue to grow and we expect this positive trend to continue throughout the year as we gain traction in the market and increase our imaging product offerings. We believe that digital imaging is a tremendous market opportunity and is an excellent complement to our core internally developed laser products.”

Gross profit as a percentage of net revenue was 40% as compared to 47% for the prior year quarter. This quarter-over-quarter decrease was primarily due to higher sales of WaterLase and diode systems internationally, which generally carry a lower margin than our direct sales in North America, and the increase in sales of our licensed imaging systems as a proportion of revenue, which also carries lower margins than our laser products.

“Based on our projected revenues and expenditures, we expect that our gross margin will return to historical levels in the range of 44% to 46% for the second quarter and 2013 overall.” Furry continued.

Operating expenses totaled $8.6 million, or 59% of net revenues, as compared to $7.4 million, or 60% of net revenues, in the 2012 first quarter. The increase of $1.2 million was primarily driven by a substantial investment in our sales and marketing efforts during the 2013 first quarter and increased legal expenses related to enforcing and protecting our intellectual property (“IP”) portfolio.

Sales and marketing expenses totaled $5.3 million for the 2013 first quarter, an increase of $1.3 million, or 30%, as compared to $4.0 million for the prior year quarter. The increase was primarily due to significantly increased convention costs as well as continued development of the Company’s direct sales force and increased media and advertising costs.

“Although we expect sales and marketing expenses to decrease overall as a percentage of revenue for 2013 as compared to 2012, many of the dental industry’s largest and most important trade shows occur during the first quarter of the year,” said Pignatelli. “Attending these shows places an additional burden on BIOLASE because our first quarter is traditionally our slowest and these events require a substantial investment. In addition to our standard trade shows, we attended the International Dental Show in Cologne, Germany, March 10-14, which is the largest dental show in the world and occurs every other year, we attended the 85th Western Veterinary Conference, and we hosted the WCLI Super Symposium, which was held March 21-24. We believe that investing in these additional marketing activities will result in increased revenues throughout the remainder of the year.”

General and administrative expenses totaled $2.2 million during the 2013 first quarter, essentially in line with the prior year quarter, despite significantly increased legal expenses primarily related to the enforcement and defense of the Company’s IP portfolio.

Pignatelli concluded, “Our IP portfolio is the cornerstone of laser technology in dentistry and a valuable asset of BIOLASE. Several of our competitors currently license our IP in their own laser products. We will not hesitate to enforce and protect our valuable IP portfolio.”

Engineering and development totaled $1.0 million during the 2013 first quarter, essentially in line with the prior year quarter.

As a result, the net loss for the 2013 first quarter totaled $2.6 million, or a loss of $0.08 per share, compared to a net loss of $1.7 million, or a loss of $0.05 per share, for the 2012 first quarter.

After removing interest expense of $87,000, non-cash depreciation and amortization expenses of $145,000, and non-cash stock-based, other equity instruments, and other non-cash compensation expense of $494,000, the 2013 first quarter resulted in non-GAAP net loss of $1.9 million, or $0.06 per share, compared with a non-GAAP net loss of $873,000, or a loss of $0.03 per share, for the 2012 first quarter.

Liquidity and Capital Resources
As of March 31, 2013, BIOLASE had approximately $5.2 million in working capital. Cash and cash equivalents totaled approximately $1.2 million at March 31, 2013, compared to $2.5 million at December 31, 2012.

Accounts receivable totaled $10.6 million at March 31, 2013, compared to $11.7 million at December 31, 2012. At March 31, 2013, the Company had two revolving credit facilities totaling $8.0 million, with $4.7 million of available borrowings, in excess of the $3.3 million outstanding. In May 2013, the total of the revolving credit facilities was increased to $10 million.

Financial Outlook
For the year ending December 31, 2013, the Company is reiterating its revenue expectation of approximately $68 million to $72 million. The midpoint of $70 million represents a 22% increase over 2012 net revenue and would also represent record revenue for the Company. The Company also reiterates that it expects to generate cash from operations for the year ending December 31, 2013.

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.

The non-GAAP financial measures presented herein have certain limitations in that they do not reflect all of the costs associated with the operations of the Company’s business as determined in accordance with GAAP.
