Intersect ENT Reports Second Quarter 2018 Results

MENLO PARK, Calif. – August 1, 2018 – Intersect ENT, Inc. (NASDAQ:XENT), a company dedicated to improving the quality of life for patients with ear, nose and throat conditions, today reported financial results for the second quarter ended June 30, 2018.

On April 1, 2018, the company announced commencement of the commercial launch of the SINUVA^® (mometasone furoate) Sinus Implant, anin-office treatment for nasal polyp disease in adult patients who have had previous sinus surgery.

“We are gratified by the initial response of patients and physicians to SINUVA, with over 325 patients treated through the second quarter. We are also pleased with the rate of payor coverage and believe that these factors, combined with our strong clinical evidence, reinforce the significant potential of SINUVA,” said Lisa Earnhardt, president and CEO of Intersect ENT. “We are meeting the challenges of the launch by taking action including expanding and leveraging the reimbursement hub and growing our sales and reimbursement teams. We remain convinced that SINUVA has a bright future and that, with these measures in place, we will be in a position to expand our launch and continue to grow PROPEL.”

Second Quarter Financial Results

Total revenue grew to $26.3 million for the second quarter 2018 compared to $24.0 million for the same period of 2017, an increase of 10%. This increase was attributable to growth in the adoption of the PROPEL^® family of steroid releasing implants as well as to the commercialization of SINUVA, which contributed 2% of revenue in the second quarter of 2018.

Gross profit for the second quarter 2018 was $20.7 million and gross margin was 79%. These results compare with gross profit of $20.3 million and gross margin of 85% in the second quarter 2017. The decrease in gross margin was attributable to increased overhead and inefficiencies largely associated with the introduction of SINUVA and to a benefit in the second quarter 2017 from the sale of PROPEL^® Contour product that was produced prior to FDA approval and therefore expensed in the fourth quarter 2016.

Operating expenses for the second quarter 2018 were $25.4 million compared to $22.9 million in the same period of 2017, an increase of 11%. R&D expenses were relatively flat at $4.4 million versus $4.2 million in the second quarter 2017. SG&A expenses increased to $21.0 million from $18.7 million, primarily driven by an increase in headcount and related expenses.

The balance of cash, cash equivalents and short-term investments were $104.9 million compared to $102.3 million at the start of the year.

Outlook

The company expects to achieve third quarter revenue in the range of $23.8 to $24.3 million, and updated full year revenue guidance to $106 to $109 million, including an estimated 2% to 4% contribution from SINUVA product sales. The company expects third quarter and full year gross margin of approximately 80% and full year operating expenses, as previously guided, in the range of $113 to $115 million.
