Conference call begins at 4:30 p.m. Eastern time today

CARLSBAD, Calif. (March 10, 2020) – Ra Medical Systems, Inc. (NYSE: RMED), a medical device company focusing on commercializing excimer laser systems to treat vascular and dermatological diseases, reports financial results for the three and 12 months ended December 31, 2019 and provides a business update.

Recent Operational Highlights

“We remain excited about the opportunity we see for the DABRA excimer laser system in the large and growing market for treating vascular disease.  Our system provides physicians with a minimally invasive approach to treat lower extremity vascular blockages by breaking down plaque into its fundamental chemical compounds using a photoablative mechanism of action,” said Andrew Jackson, Ra Medical Systems CFO and Interim CEO.  ”We are working to improve our catheter shelf life and are developing a rapid exchange platform that will allow users to advance DABRA over a guidewire to navigate the vasculature more easily.  We believe our engineering and clinical efforts are key to allowing us to reach a broader market with DABRA and building long-term shareholder value.”

Non-GAAP Financial Measures

Ra Medical has presented certain financial information in accordance with U.S. GAAP and also on a non-GAAP basis for the three-month periods and years ended December 31, 2019 and December 31, 2018. EBITDA and Adjusted EBITDA are performance measures that provide supplemental information management believes is useful to analysts and investors to evaluate Ra Medical’s ongoing results of operations, when considered alongside other GAAP measures. These measures are intended to aid investors in better understanding Ra Medical’s current financial performance and prospects for the future as seen through management. Management uses non-GAAP measures to compare the company’s performance relative to forecasts and strategic plans and to benchmark the company’s performance externally against competitors. Management believes that these non-GAAP financial measures facilitate comparisons with Ra Medical’s historical results and with the results of peer companies who present similar measures (although other companies may define non-GAAP measures differently than we define them, even when similar terms are used to identify such measures). Non-GAAP information is not prepared under a comprehensive set of accounting rules and should only be used to supplement an understanding of the company’s operating results as reported under U.S. GAAP. Ra Medical encourages investors to carefully consider its results under GAAP, as well as its supplemental non-GAAP information and the reconciliation between these presentations, to more fully understand its business. Reconciliations between GAAP and non-GAAP operating results are presented in the accompanying tables of this release.

Investors are encouraged to review the related GAAP financial measures and the reconciliation of these non-GAAP financial measures to their most directly comparable GAAP financial measures, and not to rely on any single financial measure to evaluate our business. Ra Medical defines EBITDA as our GAAP net loss as adjusted to exclude depreciation and amortization, interest income, interest expense and income tax expense.  Ra Medical defines Adjusted EBITDA as our GAAP net loss as adjusted to exclude depreciation and amortization, interest income, interest expense, income tax expense and stock-based compensation.
