Miromatrix Reports Fourth Quarter and Full Year 2022 Results and Provides Corporate Update

EDEN PRAIRIE, MN, March 31, 2023 - Miromatrix Medical Inc. (NASDAQ: MIRO), a life sciences company pioneering a novel technology for bioengineering fully transplantable organs to help save and improve patients' lives, today reported fourth quarter and full year 2022 financial results and provided a corporate update.

"Miromatrix is focused on providing patients with acute liver failure access to miroliverELAP™ as soon as possible," said Jeff Ross, Ph.D., Miromatrix CEO. "We are pioneering a new class of therapies with our bioengineered organs and believe that achieving FDA clearance to initiate a Phase 1 clinical trial for miroliverELAP will provide important validation.  To achieve this significant milestone as rapidly as possible we will be concentrating the majority of our resources on miroliverELAP over the coming months."

Business Highlights and Corporate Update

Fourth Quarter 2022 Financial Results

Unrestricted cash and investments totaled $25.2 million as of December 31, 2022, compared to $52.8 million as of December 31, 2021.  Miromatrix had $1.7 million of one-time cash outlays in the first quarter of 2022 related to the build-out of our new headquarters.  

Licensing revenue for the fourth quarter of 2022 was $930,355, compared to $8,000 in the fourth quarter of 2021. The increase in licensing revenue represents collection of minimum royalties due from Reprise Biomedical, Inc. ("Reprise") for 2020 and 2022.  The remainder of minimum royalties due from Reprise for 2021 has been deferred to 2023.  

Cost of goods sold was $125,000 for both the fourth quarter of 2022 and 2021. Cost of goods sold for both periods relates to the minimum royalty due to the University of Minnesota under our license agreement.

Operating loss for the fourth quarter of 2022 was $7.180 million, compared to $5.465 million in the fourth quarter of 2021. The increase in operating loss for comparable periods was primarily attributable to increased research and development costs and general and administrative costs; notably, cost increases relating to payroll, lab supplies and costs associated with being a public company.

Net loss for the fourth quarter of 2022 was $6.946 million, or $0.33 per share, compared to $5.476 million, or $0.27 per share in the fourth quarter of 2021. The increase in net loss for comparable periods was primarily attributable to the same cost increases described within operating loss above.          

Full Year 2022 Financial Results

Licensing revenue for 2022 was $953,470, compared to $33,066 in 2021.  The increase in licensing revenue represents collection of minimum royalties due from Reprise for 2020 and 2022.  The remainder of minimum royalties due from Reprise for 2021 has been deferred to 2023.  

Cost of goods sold was $500,000 for both 2022 and 2021.  Cost of goods sold for both periods relates to the minimum royalty due to the University of Minnesota under our license agreement.

Operating loss for 2022 was $30.364 million, compared to $16.965 million in 2021. The increase in operating loss was primarily attributable to increased research and development costs and general and administrative costs; notably, cost increases relating to payroll, lab supplies and costs associated with being a public company.

Net loss for 2022 was $29.960 million, or $1.45 per share, compared to $14.671 million, or $1.28 per share in 2021. The increase in net loss was primarily attributable to the same cost increases described within operating loss above, plus one-time gains recognized in the first quarter of 2021 that impacted the full-year comparison.

The increase in weighted average shares used in computing net loss per share for 2022 compared to 2021 is attributable to the issuance of IPO shares in June 2021.
