SAN JOSE, Calif., November 2, 2026 - SI-BONE, Inc. (Nasdaq: SIBN), the global leader in developing procedural solutions to address clinical challenges associated with compromised bone, today reported financial results for the quarter ended September 30, 2026.

“Robust third-quarter growth in procedure volumes and active physicians underscores rising demand for our diversified and differentiated platform technologies,” said Laura Francis, Chief Executive Officer. “We enter the fourth quarter with a record number of active physicians, favorable DRG changes and exceptional early uptake in our alpha launch of iFuse Granite Onyx, our new platform technology that expands our estimated total addressable market to approximately $5 billion. These drivers position us for an excellent finish to 2026 and enter 2027 with the strongest foundation for growth acceleration in our company's history.”





Third Quarter 2026 Financial Results
Worldwide revenue was $55.7 million in the third quarter 2026, a 14.5% increase from $48.7 million in the corresponding period in 2025. U.S. revenue for the third quarter 2026 was $52.8 million, a 13.9% increase from $46.4 million in the corresponding period in 2025. U.S. revenue growth benefited from approximately 19.5% growth in procedure volume partially offset by lower average selling price due to procedure mix and the growing interventional spine physician demand for the INTRA platform in the office-based and ASC sites of care. International revenue for the third quarter 2026 was $2.9 million, a 27.0% increase from $2.3 million in the corresponding period in 2025. International revenue growth reflects the increasing adoption of iFuse TORQ and iFuse TORQ TNT.

Gross profit was $44.2 million in the third quarter 2026, an increase of 13.7% from $38.8 million in the corresponding period in 2025. Gross margin was 79.3% for the third quarter 2026, compared to 79.8% in the corresponding period in 2025 driven by procedure and site of care mix.

Operating expenses increased 9.7% to $48.5 million in the third quarter 2026, as compared to $44.2 million in the corresponding period in 2025. The increase was primarily driven by higher sales commissions on increased revenue, marketing to support new product launches and continued investment in research and development.

Operating loss improved by 19.2% to $4.4 million in the third quarter 2026, as compared to an operating loss of $5.4 million in the corresponding period in 2025.

Net loss improved by 20.7% to $3.6 million, or $0.08 per diluted share, in the third quarter 2026, as compared to a net loss of $4.6 million, or $0.11 per diluted share, in the corresponding period in 2025.

Adjusted EBITDA was $3.0 million in the third quarter 2026, improving from an adjusted EBITDA of $2.3 million in the corresponding period in 2025.



Cash and equivalents as of September 30, 2026 were $146.3 million, compared to $145.9 million as of June 30, 2026. Net cash generated was $0.4 million in the third quarter 2026, compared to $0.2 million in net cash generated during the corresponding period in 2025.

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, 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 or deterioration in economic conditions as a result of tariffs and retaliation by U.S. trading partners on the ability and desire of patients to undergo elective procedures including those using SI-BONE’s products, SI-BONE’s ability to manage risks to its supply chain, future capital requirements driven by new surgical systems requiring instrument tray and implant inventory 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 products. 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 SI-BONE’s most recent filings on Form 10-K and Form 10-Q, and SI-BONE’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.



Use of Non-GAAP Financial Measures
To supplement our condensed consolidated financial statements, which are prepared and presented in accordance with generally accepted accounting principles in the United States ("GAAP"), SI-BONE uses two non-GAAP financial measures: Adjusted EBITDA and free cash flow. Non-GAAP measures should be considered supplemental to, and not a substitute for, financial information prepared in accordance with GAAP. Adjusted EBITDA excludes the effect of items that increase or decrease SI-BONE’s reported results of operations. Free cash flow is not intended to represent our residual cash flow available for discretionary expenditures. 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 and free cash flow may differ from similarly titled measures used by others.

Adjusted EBITDA excludes from net loss the effects of interest income, interest expense, depreciation and amortization, and stock-based compensation. Free cash flow is defined as net cash provided by operating activities less purchases of property and equipment. SI-BONE believes the presentation of these financial measures 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 non-GAAP financial measures 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.
