“I am thrilled to announce another record revenue quarter and fiscal year for ProSomnus, as we establish the ProSomnus EVO® precision intraoral technology as a truly differentiated therapy for Obstructive Sleep Apnea,” said Len Liptak, Chief Executive Officer. “The team worked tremendously towards executing on our strategic deliverables, and achieved a record number of procedures in both Q4 and the full year. 2023 was an impactful year, as we continued to generate and share strong clinical data supporting the use of ProSomnus precision oral appliance therapy as a first line therapy for Obstructive Sleep Apnea, advanced enrollment in the Severe Obstructive Sleep Apnea study, and prepared a robust dossier to support a premarket submission to the FDA earlier this year for label expansion to include severe OSA. We continued to fine-tune our operations in an effort to progress towards cash flow breakeven while maintaining strong top line growth.  In all, it was a tremendous year of achievements as we advance our mission to position ProSomnus as the leading non-CPAP therapy for Obstructive Sleep Apnea. I am proud of the 2023 results, and I look forward to building upon this momentum during 2024.”

Financial Results for the Fourth Quarter and Year Ended December 31, 2023

Revenues increased to $7.8 million for the fourth quarter ended December 31, 2023.  This reflects an increase of $0.8 million, or 11%, and $2.0 million, or 35%, compared to the quarters ended September 2023 and December 2022, respectively.  Revenue for the full year 2023 increased to $27.7 million, an increase of $8.3 million, or 43%, compared to the year ended December 31, 2022. This increase was primarily driven by increased adoption of our precision devices, increased sales and marketing investments, and mix shift to the EVO Product, all of which contributed to increased unit volumes.

Cost of revenue totaled $4.1 million for the fourth quarter ended December 31, 2023, representing 53% of revenue. This reflects an increase of $0.6 million, or 15%, and $1.4 million, or 54%, compared to the quarters ended September 2023 and December 2022, respectively.  For the full year 2023 cost of revenue totaled $13.6 million, representing 49% of revenue, an increase of $4.5 million, or 49%, compared to $9.1 million, or 47% of revenue, for the year ended December 31, 2022. The increase was primarily due to product costs associated with higher sales volume of our devices and increased overhead stemming from our move into our new manufacturing facility during early 2023.

Sales and marketing expenses totaled $3.4 million for the fourth quarter ended December 31, 2023. Relative to the quarter ended June 30, 2023, the commencement of our expense reduction initiative, sales and marketing has decreased 6% and as percentage of revenue has decreased from 53% to 43% for the quarters ended December 31, 2023 and June 30, 2023, respectively.  Fourth quarter 2023 sales and marketing expense reflects a modest increase compared to the quarter ended September 2023, and an increase of $1.0 million, or 40%, compared to the quarter ended December 2022. Sales and marketing expenses for the full year 2023 totaled $13.1 million, an increase of $4.2 million, or 48%, compared to the year ended December 31, 2022. This year-over-year increase reflects an increase in personnel and consulting-related expenses of $2.7 million due to expansion of the sales team during mid-2023, distribution, marketing events, and advertising expenses of $1.2 million, and commissions paid on higher revenues.

General and administrative expenses totaled $4.0 million for the quarter ended December 31, 2023. Relative to the quarter ended June 30, 2023, general and administrative expenses decreased 11% and as percentage of revenue has decreased from 65% to 51% for the quarters ended December 31, 2023 and June 30, 2023, respectively.  Fourth quarter 2023 general and administrative expenses reflect an increase of $0.5 million, or 16%, compared to the quarter ended September 2023, and a decrease of $1.7 million, or 30%, compared to the quarter ended December 2022.  For the full year 2023 general and administrative expenses totaled $15.2 million, an increase of $5.3 million, or 54%, compared to $9.9 million for the year ended December 31, 2022. This increase was driven primarily by $2.9 million increase in costs that scale with top line and production growth including credit card fees, utilities, rent and depreciation associated with the new manufacturing facility, and public company expenses including $2.5 million increase in professional services, $1.3 million increase in personnel costs, and $1.0 million in insurance, partially offset by $1.4 million decrease in stock-based compensation.

Research and development expenses totaled $1.4 million for the quarter ended December 31, 2023. Relative to the quarter ended June 30, 2023, the commencement of our expense reduction initiative, research and development expenses remained consistent and as percentage of revenue has decreased from 20% to 17% for the quarters ended December 31, 2023 and June 30, 2023, respectively.  Fourth quarter 2023 reflects an increase of $0.3 million, or 31.4%, and $0.3 million, or 28% compared to the quarters ended September 2023 and December 2022, respectively. For the full year 2023 research and development expenses totaled $4.8 million, an increase of $1.8 million, or 61%, compared to the year ended December 31, 2022. This increase was primarily driven by an increase in expenses associated with the ongoing development of the RPMO₂, the Front Line OSA Therapy (“FLOSAT”) clinical study and costs associated with preparing the 510(k) Premarket Notification to U.S. Food and Drug Administration for the severe indication label expansion.

Other income (expense) is comprised of interest expense and accounting charges associated with changes in fair values of certain assets and liabilities and charges associated with financings and debt restructuring. Total other expense for the year ended December 31, 2023 aggregated to $5.0 million compared to total other income of $4.3 million for the year ended December 31, 2022. The other income resulting from the valuation changes in certain of our liabilities reflect the price decline of our publicly traded stock which is a significant input into the fair value valuation assumptions for the liabilities revalued. This other income was offset during 2023 by a loss on debt restructuring associated with changes in the terms of certain of our senior and subordinate indentures as part of our September 2023 financing transactions. Interest expense reflects the interest on our senior and subordinate indentures and equipment financing liabilities.

Cash and restricted cash at December 31, 2023 totaled $7.1M, reflecting a decrease of $4.9 million from the $12.0 million reported at September 30, 2023. The decrease noted includes approximately $1.0 million of cash used to renew the Company’s insurance policies during December 2023.
