SANTA CLARA, Calif. August 7, 2023 - SI-BONE, Inc. (Nasdaq:SIBN), a medical device company dedicated to solving musculoskeletal disorders of the sacropelvic anatomy, today reported financial results for the quarter ended June 30, 2023.

Record worldwide revenue of $33.3 million for the second quarter 2023, representing approximately 30% growth over the corresponding period in 2022
Record U.S. revenue of $31.2 million for the second quarter 2023, representing approximately 31% growth over the corresponding period in 2022
Gross margin of 81% for the second quarter 2023

$169 million in cash and equivalents at the end of the quarter, including $84 million in net proceeds from follow-on offering in May 2023
“I am pleased with the over 30% U.S. revenue growth in the second quarter of 2023, led by increasing demand for our solutions. Having consistently delivered several consecutive quarters of record revenue and operating leverage, we are excited about the significant opportunity ahead of us as we capitalize on underlying business momentum and progress towards profitability,” said Laura Francis, Chief Executive Officer of SI-BONE, Inc. “As we look beyond 2023, we are focused on judiciously investing in long-term growth drivers, including portfolio expansion programs as well as physician engagement initiatives to extend our market leadership and build a sustainable and high-growth revenue platform.”

Second Quarter 2023 Financial Results

Worldwide revenue was $33.3 million in the second quarter 2023, a 30% increase from $25.6 million in the corresponding period in 2022. U.S. revenue for the second quarter 2023 was $31.2 million, a 31% increase from $23.8 million in the corresponding period in 2022. International revenue for the second quarter 2023 was $2.1 million, a 15% increase from $1.8 million in the corresponding period in 2022.

Gross margin was 81% for the second quarter 2023, as compared to 86% in the corresponding period in 2022. Gross margin in the second quarter 2023 was impacted by procedure and product mix given the higher total costs of iFuse-TORQ and iFuse Bedrock Granite. Gross margin also includes the impact of higher depreciation from instrument trays to support the growth of the business and depreciation associated with our second facility in Santa Clara.

Operating expenses decreased 3% to $38.9 million in the second quarter 2023, as compared to $40.0 million in the corresponding period in 2022. The change in operating expenses was primarily driven by timing of certain commercial activities, partially offset by higher commissions and stock-based compensation.

Operating loss improved by 33% to $12.0 million in the second quarter 2023, as compared to an operating loss of $17.9 million in the corresponding period in 2022.

Net loss improved by 39%, to $11.2 million, or $0.30 per diluted share for the second quarter 2023, as compared to a net loss of $18.5 million, or $0.54 per diluted share in the corresponding period in 2022. Net loss per diluted share for the second quarter 2023 also includes the impact of increase in shares outstanding as a result of a follow-on common stock offering in May 2023.

Adjusted EBITDA loss improved by approximately 59% to negative $4.7 million, in the second quarter 2023, as compared to an adjusted EBITDA loss of negative $11.5 million, in the corresponding period in 2022.

Cash and marketable securities were $169.4 million and borrowings were $36.0 million as of June 30, 2023. The cash and marketable securities include $84 million in net proceeds from the May 2023 follow-on offering.

Forward Looking Statements

The statements in this press release regarding expectations of future events or results, including SI-BONE’s expectations of continued revenue and procedure growth and financial outlook, contained in this press release are "forward-looking" statements. These forward-looking statements are based on SI-BONE's current expectations and inherently involve significant risks and uncertainties. These risks include SI-BONE's ability to introduce and commercialize new products and indications, SI-BONE's ability to maintain favorable reimbursement for procedures using its 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, SI-BONE's ability to manage risks to its supply chain, future capital requirements driven by new surgical systems requiring instrument tray investment, and the pace of the re-normalization of the healthcare operating environment including the ability and desire of patients and physicians to undergo and perform procedures using SI-BONE's devices. 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 (, 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.

Use of Non-GAAP Financial Measures

SI-BONE uses adjusted EBITDA, a non-GAAP financial measures that excludes from net loss the effects of interest income, interest expense, depreciation and amortization and stock-based compensation. SI-BONE believes the presentation of adjusted EBITDA is useful to management because it allows management to more consistently analyze period-to-period financial performance and provides meaningful supplemental information with respect to core operational activities used to evaluate management's performance. SI-BONE also believes the presentation of adjusted EBITDA is useful to investors and other interested persons as it enables these persons to use this additional information to assess the company’s performance in using this additional metric that management uses to assess the company’s performance.

Adjusted EBITDA should be considered supplemental to, and not a substitute for, financial information prepared in accordance with GAAP. Because adjusted EBITDA excludes the effect of items that increase or decrease SI-BONE's reported results of operations, management strongly encourages investors to review, when they become available, the company's consolidated financial statements and publicly filed reports in their entirety. The company's definition of adjusted EBITDA may differ from similarly titled measures used by others.
