MINNEAPOLIS, Minnesota - May 2, 2023 - Inspire Medical Systems, Inc. (NYSE: INSP) (Inspire), a medical technology company focused on the development and commercialization of innovative, minimally invasive solutions for patients with obstructive sleep apnea (OSA), today reported financial results for the quarter ended March 31, 2023.

•Generated revenue of $127.9 million in the first quarter of 2023, an 84% increase over the same quarter last year

•Achieved gross margin of 84.4% in the first quarter of 2023

•Activated 68 new centers in the U.S. in the first quarter of 2023, bringing the total to 973 U.S. medical centers providing Inspire therapy

•Created 17 new U.S. sales territories in the first quarter of 2023, bringing the total to 242 U.S. sales territories

•Finalized countrywide reimbursement in Belgium

•Received FDA approval for pediatric patients with Down syndrome

"We are excited about our strong performance during the first quarter as the team remained focused on high-quality patient outcomes and delivered exceptional results. Our growth was driven primarily by the increased utilization at existing sites and complemented by the addition of 68 new implanting centers and 17 additional U.S. sales territories," said Tim Herbert, President and Chief Executive Officer of Inspire Medical Systems. "Based on the strong momentum we are seeing in our business, we are raising our full year 2023 revenue guidance to between $580 million to $590 million, an increase from our prior guidance of $560 million to $570 million."

"We also achieved two important milestones in the first quarter," continued Mr. Herbert. "The first was the FDA approval for the pediatric Down syndrome population for patients who are at least 13 years of age. The research has been ongoing for several years and many third-party payers, including Medicare, provide coverage for this population, improving a family’s access to care. The second was countrywide reimbursement approval in Belgium at rates consistent with other countries around the world and the team is already expanding patients’ access to care by opening additional centers and training healthcare providers.”

Revenue was $127.9 million for the three months ended March 31, 2023, an 84% increase from $69.4 million in the corresponding period in the prior year. U.S. revenue for the quarter was $124.5 million, an increase of 87% as compared to the prior year quarter. First quarter revenue outside the U.S. was $3.4 million, an increase of 15% as compared to the first quarter of 2022.

Gross margin was 84.4% for the three months ended March 31, 2023, compared to 85.6% for the corresponding prior year period, with the reduction primarily due higher costs of certain component parts somewhat offset by the May 2022 price increase which is substantially in effect across our U.S. customer base.

Operating expense increased to $127.5 million for the first quarter of 2023, as compared to $75.4 million in the corresponding prior year period, an increase of 69%. This increase primarily reflected ongoing investments in the expansion of the U.S. sales organization, direct-to-patient marketing programs, continued product development efforts, as well as increased general corporate costs.

Net loss was $15.4 million for the first quarter of 2023, as compared to $16.7 million in the corresponding prior year period. The diluted net loss per share for the first quarter of 2023 was $0.53 per share, as compared to $0.61 in the prior year period.

As of March 31, 2023, cash, cash equivalents, and investments increased to $452.1 million from $451.4 million on December 31, 2022.

Given the positive trends during the first quarter, Inspire is increasing its full year 2023 revenue guidance to between $580 million to $590 million, which would represent growth of 42% to 45% over full year 2022 revenue of $407.9 million. This compares to the prior revenue guidance of $560 million to $570 million.

The Company is maintaining its full year 2023 gross margin guidance of 83% to 85%.

Inspire is also maintaining its guidance relating to the opening of new U.S. medical centers of 52 to 56 per quarter, as well as its guidance of 12 to 14 new U.S. territories per quarter for the remainder of 2023.

Inspire’s management will host a conference call after market close today, Tuesday, May 2, 2023, at 5:00 p.m. Eastern Time to discuss these results and answer questions.
