First Quarter 2022 Financial Results

Worldwide revenue was $22.4 million in the first quarter 2022, a 10% increase from $20.4 million in the corresponding period in 2021. U.S. revenue for the first quarter 2022 was $20.4 million, a 9% increase from $18.8 million in the corresponding period in 2021. International revenue for the first quarter 2022 was $2.1 million, a 24% increase from $1.7 million in the corresponding period in 2021.

Gross margin was 87% for the first quarter 2022, as compared to 89% in the corresponding period in 2021. Gross margin in the first quarter 2022 was impacted by lower average selling prices due to procedure and site of service mix, as well as an increase in cost of operations to support the growth of the business.

Operating expenses increased 22% to $36.3 million in the first quarter 2022, as compared to $29.8 million in the corresponding period in 2021. The increase was driven by higher sales and marketing expenses related to sales force expansion, higher travel costs, research and development investment and increased stock-based compensation.

Operating loss was $16.9 million in the first quarter 2022, as compared to an operating loss of $11.6 million in the corresponding period in 2021.

Net loss was $17.4 million, or $0.52 per diluted share for the first quarter 2022, as compared to a net loss of $12.2 million, or $0.37 per diluted share in the corresponding period in 2021.

Cash and marketable securities were $130.7 million and long-term borrowings were $35.0 million as of March 31, 2022.

SI-BONE is encouraged by the strong momentum in the business, but remains cognizant of the uncertainty surrounding COVID-19 and its impact on elective procedures as well as hospital and ASC infrastructure and staffing levels. The Company continues to expect total 2022 revenue of approximately $106 million to $108 million, representing growth of 18% to 20% compared to full year 2021.

About SI-BONE, Inc.

SI-BONE (NASDAQ: SIBN) is a global leader in technology for surgical treatment of musculoskeletal disorders of the sacropelvic anatomy. In 2009, SI-BONE introduced the iFuse Implant System for minimally invasive surgery of the SI joint, shown to be a source of pain in 15% to 30% of chronic low back pain. Since then, more than 2,700 surgeons have performed a combined total of more than 65,000 SI joint fusion procedures. A unique body of evidence, supporting the triangular iFuse implant, including two RCT’s and over 100 peer reviewed publications, has enabled multiple government and private insurance payors to establish coverage of the SI joint fusion procedure exclusively when performed with SI-BONE's triangular iFuse implant. SI-BONE is leveraging its market leadership position, supported by this proprietary reimbursement advantage, to commercialize other devices intended for surgical treatment of related aspects of the human anatomy.
