Safe Harbor Statement

This presentation contains "forward-looking statements," which are statements related to events, results, activities or developments that SI-BONE expects, believes or anticipates will or

may occur in the future. Forward-looking often contain words such as "intends," "estimates," "anticipates," "hopes," "projects," "plans," "expects," "seek," "believes," "see," "should," "will,"

"would," "target," and similar expressions and the negative versions thereof. Such statements are based on SI-BONE's experience and perception of current conditions, trends, expected future developments and other factors it believes are appropriate under the circumstances, and speak only as of the date made. Forward-looking statements are inherently uncertain and actual results may differ materially from assumptions, estimates or expectations reflected or contained in the forward-looking statements as a result of various factors. Risks to SI-BONE's results include the company's ability to introduce and commercialize new products and indications, its ability to maintain favorable reimbursement for procedures using its products, changes in payor requirements for authorization of procedures involving SI-BONE's products,the impact of any future economic weakness on the ability and desire of patients to undergo elective procedures including those using SI-BONE's devices, its ability to manage risks to its supply chain, and future capital requirements driven by new surgical systems requiring instrument tray investment. Actual results and the timing of events could differ materially from those anticipated in such forward-looking statements as a result of these and other risks and uncertainties, many of which are described in the company's most recent filings on Form 10-K and Form 10-Q, and the company's other filings with the Securities and Exchange Commission (SEC) available at the SEC's Internet site (www.sec.gov), especially under the caption "Risk Factors". SI-BONE does not undertake any obligation to update forward-looking statements and expressly disclaims any obligations or undertaking to release publicly any updates or revisions to any forward-looking statements contained herein, except as required by law.

This presentation includes certain non-GAAP measures, including Adjusted EBITDA. For a reconciliation of such non-GAAP measures to GAAP accounting metrics, please refer to the final page of this presentation or SI-BONE's most recent earnings release.
