"We are pleased to report first quarter results where we began to capitalize on recent, exclusive U.S. reimbursement coverage decisions with execution on sales force expansion and surgeon education," said Jeffrey Dunn, President, Chief Executive Officer, and Chairman. "I am encouraged by the momentum we are building and remain confident that we are executing toward our goals and that our business outlook remains strong.

First Quarter 2019 Financial Results

Revenue was $15.0 million in the first quarter of 2019, an 18% increase from $12.7 million in the corresponding prior year period. U.S. revenue was $13.5 million, an increase of 19% from the corresponding prior year period, and international revenue was $1.5 million, an increase of 9% from the corresponding prior year period. The increase primarily was driven by improvement in domestic and international case volumes.

Gross margin was 90% for the first quarter of 2019, as compared to 92% in the corresponding prior year period. The change in gross margin was due to an increase in personnel in operations to support the growth of the business.

Operating expenses were $22.3 million in the first quarter of 2019, as compared to $14.6 million in the corresponding prior year period, an increase of 53%. The increase in operating expense primarily was driven by a step-up in sales hiring, more surgeon training, and additional advertising and marketing. In addition, we incurred higher general and administrative expenses from new public company costs and increased stock-based compensation expenses.

Operating loss was $8.8 million in the first quarter of 2019, as compared to $2.9 million in the corresponding prior year period.

Net loss was $9.3 million, or $0.38 per diluted share for the first quarter of 2019, as compared to $4.2 million, or $1.17 per diluted share in the corresponding prior year period.

SI BONE is a medical device company that pioneered the iFuse Implant System, a minimally invasive surgical system for fusion of the sacroiliac joint to treat sacroiliac joint dysfunction. The SI joint is the last major joint with a clinically proven surgical treatment. The iFuse Implant, commercially available since 2009, is the only SI joint fusion device supported by multiple prospective clinical studies showing improved pain, patient function and quality of life resulting from treatment. There are over 65 peer reviewed publications supporting the safety, durable effectiveness, and biomechanical and economic benefits unique to the iFuse Implant (www.si-bone.com/results). This body of evidence has enabled multiple government and private insurance payors to establish coverage of the SI joint fusion procedure exclusively when performed with the iFuse Implant System.

The iFuse Implant System is intended for sacroiliac fusion for conditions including sacroiliac joint dysfunction that is a direct result of sacroiliac joint disruption and degenerative sacroiliitis. This includes conditions whose symptoms began during pregnancy or in the peripartum period and have persisted postpartum for more than 6 months. The iFuse Implant System is also intended for sacroiliac fusion to augment immobilization and stabilization of the sacroiliac joint in skeletally mature patients undergoing sacropelvic fixation as part of a lumbar or thoracolumbar fusion. There are potential risks associated with the iFuse Implant System. It may not be appropriate for all patients and all patients may not benefit.
