Recent Operational Highlights

Business and operational highlights from the first quarter of 2022 and recent weeks include the following:

“I’m encouraged by recent progress in our pivotal atherectomy clinical trial with 107 of the planned 125 subjects now enrolled, including 9 since our last update in late March,” said Will McGuire, Ra Medical Systems CEO. “In addition, we continue to work with the FDA to support their review of the 510(k) application we submitted in February for our next-generation DABRA 2.0 catheter. Finally, given the current economic environment, management and our board of directors are conducting a review of strategic alternatives, and we have engaged an investment bank as a part of this process with the goal of maximizing shareholder value. I look forward to providing further details about this process when appropriate.”

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 ended March 31, 2022 and 2021. 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 U.S. GAAP, as well as its supplemental non-GAAP information and the reconciliation between these presentations, to more fully understand its business. Reconciliations between U.S. GAAP and non-GAAP operating results are presented in the accompanying tables of this news release.

Investors are encouraged to review the related U.S. 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 loss from continuing operations as adjusted to exclude depreciation and amortization, interest income, interest expense and income tax expense. Ra Medical defines Adjusted EBITDA as EBITDA adjusted to exclude stock-based compensation, and gain and loss on sales and disposals of property and equipment.
