BIOLASE REPORTS 2014 SECOND QUARTER RESULTS

IRVINE, CA (August 7, 2014) — BIOLASE, Inc. (NASDAQ:BIOL), the world’s leading manufacturer and distributor of dental lasers, today reported unaudited financial results for the second quarter and six months ended June 30, 2014.

Net revenue for this year’s second quarter was $10.2 million compared to $14.2 million in the second quarter of 2013. Net revenue for the first six months of 2014 was $21.7 million, compared to $28.8 million in the same period in 2013. The overall decrease in period-to-period net revenue reflected a decline in domestic and international laser system revenue, as well as a decline in imaging systems and consumables and other net revenue, partially offset by a slight increase in services revenue.

The net loss for the quarter ended June 30, 2014 totaled $6.4 million, or $0.17 per share, compared to a net loss of $2.6 million, or $0.08 per share, for the same prior year period. The net loss for the six months ended June 30, 2014 was $11.3 million, or $0.31 per share, compared to a net loss of $5.2 million, or $0.16 per share, for the same prior year period.

Commenting on the results, Jeffrey M. Nugent, Acting Chief Executive Officer, said, “Our results for the quarter and six months ended June 30, 2014 clearly demonstrate why BIOLASE needed new leadership. The Company’s performance under the prior CEO, who resigned two weeks before the second quarter ended, was unacceptable and does not reflect the Company’s true potential to deliver value for customers and stockholders.

“We are actively implementing a turnaround plan, which included raising $12 million in new capital in July, retiring all of our $2.9 million in Comerica debt, and addressing issues with suppliers,” continued Nugent. “We are also focused on improving customer service, product quality and clinical support and financial discipline. Our strategy also calls for increased innovation, which will allow us to fully capitalize on our technologies and the core strengths of our business. We expect our renewed focus and strategic plan to result in improved revenues during the remainder of 2014 and into 2015.

“We are pleased that former Chairman and CEO Federico Pignatelli has resigned from the Board and dropped his threat of a proxy fight. It was the right thing to do,” concluded Nugent.

Additional Q2 Information
As a result of a new warranty program for the Company’s WaterLase systems, gross profit decreased from 39.0% of net revenue for the second quarter ended June 30, 2013 to 36.6% of net revenue for this year’s second quarter. In late June 2014, after the resolution of our corporate governance issues, BIOLASE extended the warranty on its WaterLase systems from one year to two years, effective for systems purchased after January 1, 2014. This warranty change resulted in an additional expense of approximately $250,000 during the quarter and six months ended June 30, 2014. This change was made as a strong signal to customers that BIOLASE is confident in the performance of its products and will stand behind them for an additional year of warranty coverage. Management expects gross profit to improve if there is success in increasing revenue from sales of the Company’s core laser systems in the third and fourth quarters of this year.

Operating expenses in the second quarter and first six months ended June 30, 2014 were $9.9 million and $18.5 million, respectively, compared to $7.9 million and $16.5 million in the same prior year periods. The primary driver of the increase during the second quarter and first six months of 2014 was increased legal fees of $2.5 million and $3.2 million for the quarter and six months ended June 30, 2014, respectively, incurred by the Company at the direction of its former Chairman and CEO in connection with the litigation to resolve the dispute over our corporate governance and the composition of BIOLASE’s Board.

After removing interest expense of $185,000, income tax provision of $29,000, non-cash depreciation and amortization expenses of $177,000, and non-cash stock-based compensation expense of $338,000, the non-GAAP net loss for this year’s second quarter was $5.7 million, or $0.15 per share, compared with a non-GAAP net loss of $1.7 million, or $0.05 per share, for the same prior year period.

The non-GAAP net loss was $9.8 million, or $0.26 per share, for the six months ended June 30, 2014 compared with a non-GAAP net loss of $4.0 million, or $0.12 per share, for the same prior year period.

Liquidity and Capital Resources
As of June 30, 2014, the Company had a working capital deficit of approximately $1.2 million. Cash and cash equivalents totaled approximately $2.1 million at June 30, 2014, compared to $1.4 million at December 31, 2013.

On July 22, 2014, the Company sold 6,250,000 unregistered shares of common stock at an undiscounted market price of $1.92 per share. Gross proceeds from the sale were $12 million. The Company expects net proceeds of approximately $11.7 million after expected offering expenses of approximately $300,000.

Also on July 28, 2014, the Company paid in full all amounts due under the revolving lines of credit with Comerica Bank, including principal, accrued interest, and fees which totaled approximately $2.9 million, and the credit facilities were terminated.
