Intersect ENT Reports Fourth Quarter and Full Year 2018 Results

ENCORE Clinical Study Completed, Primary Endpoints Met

MENLO PARK, Calif.—February 25, 2019 — 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 fourth quarter and full year ended December 31, 2018.

Recent Business Highlights

 

•

In December 2018, the company commenced enrollment in the study of its newest platform product, the ASCEND investigational drug-coated sinus balloon. This novel device is designed to deliver a corticosteroid (mometasone furoate) directly to the sinuses at the time of dilation.

 

•

In November 2018, the International Forum of Allergy and Rhinology published a pooled analysis of the company’s PROPEL® Contour and PROPEL® Mini steroid releasing sinus implants showing improved outcomes of frontal sinus surgery. The pooled analysis showed that the PROPEL frontal steroid releasing implants significantly improved endoscopic outcomes of frontal sinus surgery compared to surgery alone.

In addition, the company announced today the completion of the ENCORE study, a 50-patient multicenter, open-label study focused on evaluation of the safety of repeat placement of SINUVA in a population of chronic sinusitis patients with nasal polyps. Study findings showed zero serious adverse events related to the implants during the measurement period and zero serious adverse events related to repeat placement.

Fourth Quarter Financial Results

Total revenue grew to $32.8 million for the fourth quarter of 2018 compared to $29.5 million for the same period of 2017, an increase of 11%. This increase was attributable to growth in the adoption of the PROPEL^® family of steroid releasing implants as well as to commercialization of the SINUVA^® (mometasone furoate) Sinus Implant, which contributed approximately 4% of revenue, or $1.2 million, in the fourth quarter of 2018.

Gross profit for the fourth quarter 2018 was $26.4 million and gross margin was 81%, compared to gross profit of $24.4 million and gross margin of 83% for the same period of 2017. The decrease in gross margin was attributable to increased overhead and inefficiencies primarily associated with the introduction of SINUVA.

Operating expenses for the fourth quarter of 2018 were $32.1 million, compared to $27.9 million in the same period of 2017, an increase of 15%. R&D expenses increased to $5.7 million from $5.6 million. SG&A expenses increased to $26.3 million from $22.3 million, primarily due to an expansion of SINUVA commercial and market access activities, including headcount, marketing and consulting expenses.

Full Year 2018 Financial Results

Total 2018 revenue grew to $108.5 million compared to $96.3 million in 2017, an increase of 13%. This increase was attributable to growth in the adoption of the PROPEL family of steroid releasing implants as well as to commercialization of SINUVA, which contributed 3% of revenue, or $2.8 million, in 2018.

Gross profit for 2018 was $85.9 million and gross margin was 79%, compared to gross profit of $80.8 million and gross margin of 84% for 2017. The decrease in gross margin was attributable primarily to increased overhead and inefficiencies associated with the introduction of SINUVA.

2018 operating expenses were $110.9 million compared to $98.4 million in 2017, an increase of 13%. R&D expenses increased to $19.3 million from $18.4 million due to an increase in headcount expense and clinical trial activities. SG&A expenses increased to $91.6 million from $80.0 million, primarily due to an increase in headcount expense.

The balance of cash, cash equivalents and short-term investments was $100.8 million compared to $102.3 million at the start of the year.

Outlook

Intersect ENT continues to forecast 2019 revenue in the range of $123 to $127 million and first quarter revenue in the range of $26.0 to $26.5 million. The Company’s 2019 outlook for gross margin is in the range of 80-81% and for expenses in the range of $135 to $137 million.
