Robust Balance Sheet to Execute Growth Strategies in 2022
Full Year 2022 Revenue Growth Outlook +10%

LAKE FOREST, Calif., March 17, 2022 /PRNewswire/ -- BIOLASE, Inc. (NASDAQ:BIOL), the global leader in dental lasers, today announced its financial results for the fourth quarter and full year ended December 31, 2021.

2021 Fourth Quarter and Recent Highlights

Total revenue was 12.4 million, up 46% year over year
Total revenue also increased 22% over fourth quarter 2019 pre-COVID results
U.S. laser sales increased 39% year over year and U.S. consumable sales increased 40% year over year, driven by significantly increased procedures using BIOLASE lasers
International laser sales increased 87% year over year and international consumable sales increased 29% year over year, driven by significantly increased procedures using BIOLASE lasers
Higher average selling price and sales volumes resulted in 40% gross margin for the quarter, a significant improvement from a year ago
Continued momentum with new customers and dental specialists
FDA clearance received for the new EdgePRO laser, which was co-developed with EdgeEndo, a global leader in commercializing products for the endodontics market
Maintained robust balance sheet with cash and cash equivalents of $30.0 million on December 31, 2021

"Our strong fourth quarter and full year performance reflects the rising demand for our industry-leading dental lasers," commented John Beaver, President and Chief Executive Officer. "Furthermore, our robust balance sheet and continued business momentum allowed us to enter 2022 in a favorable position to achieve our operating objectives for the year.

"With only about 7% of the U.S. dental community currently using dental lasers, we are confident in our ability to drive further adoption of this new standard of care. The positive clinical data published in 2021 on the use of dental lasers, combined with the launch of our specialist academies for endodontists, periodontists, pediatric dentists, and dental hygienists is generating increased adoption of laser technology. These initiatives, along with the continued success of our Waterlase Exclusive Trial Programs and our further penetration into the DSO space, positions us for continued revenue growth in 2022. With every one percentage point increase in market adoption of laser technology in the U.S. alone, we estimate it will generate an additional $50 million in revenue for BIOLASE, assuming we keep our same 60% market share."

2021 Fourth Quarter Financial Results

Net revenue for the fourth quarter of 2021 was $12.4 million, an increase of 46% year over year. Compared to the fourth quarter of 2019, which was the last full quarter prior to the impact of the COVID-19 pandemic, revenue increased 22% from $10.2 million. U.S. laser revenue was $5.3 million for the fourth quarter of 2021, up 39% when compared to U.S. laser revenue of $3.8 million for the fourth quarter of 2020.

Gross margin for the fourth quarter of 2021 was 40%, compared to 19% for the fourth quarter of 2020.

Non-GAAP Financial Measures

In addition to the financial information prepared in conformity with generally accepted accounting principles in the U.S. ("GAAP"), this press release includes certain historical non-GAAP financial information. Management believes that these non-GAAP financial measures assist investors in making comparisons of period-to-period operating results and that, in some respects, these non-GAAP financial measures are more indicative of the Company's ongoing core operating performance than their GAAP equivalents.

Adjusted EBITDA is defined as net loss before interest, taxes, depreciation and amortization, allowance for doubtful accounts, loss on patent litigation settlement, stock-based and other non-cash compensation, debt forgiveness, and other income, net. Management uses Adjusted EBITDA in its evaluation of the Company's core results of operations and trends between fiscal periods and believes that these measures are important components of its internal performance measurement process. Therefore, investors should consider non-GAAP financial measures in addition to, and not as a substitute for, or as superior to, measures of financial performance prepared in accordance with GAAP. Further, the non-GAAP financial measures presented by the Company may be different from similarly named non-GAAP financial measures used by other companies.
