Exhibit 99.1

Miromatrix Reports Third Quarter 2023 Results

EDEN PRAIRIE, MN, November 14, 2023 - Miromatrix Medical Inc. (Nasdaq: MIRO) (the “Company”), a life sciences company pioneering a novel technology for bioengineering fully transplantable organs to help save and improve patients' lives, today reported third quarter 2023 financial results.

Due to the Company’s pending proposed transaction with United Therapeutics Corporation (Nasdaq: UTHR) (“United Therapeutics”), the Company’s management has suspended guidance for 2023 and will not hold a conference call to discuss third quarter 2023 results.

Third Quarter 2023 Financial Results

Unrestricted cash and investments totaled $16.1 million as of September 30, 2023, compared to $20.4 million as of June 30, 2023.

Operating loss was $6.6 million and $21.4 million for the three- and nine-month periods ended September 30, 2023, respectively, as compared to $7.8 million and $23.2 million for the three- and nine- month periods ended September 30, 2022, respectively. The decrease in operating loss for comparable periods was primarily attributable to reduced research and development spending.

Net loss was $6.5 million and $20.5 million for the three- and nine-month periods ended September 30, 2023, respectively, as compared to $7.6 million and $23.0 million for the three- and nine- month periods ended September 30, 2022, respectively. The decrease in net loss for comparable periods was primarily attributable to reduced research and development spending, in addition to a one-time employee retention credit totaling $0.5 million that was recorded as other income in the first quarter of 2023.

Miromatrix Agrees to be Acquired by United Therapeutics Corporation

On October 30, 2023, the Company announced that it had entered into a definitive merger agreement with United Therapeutics pursuant to which United Therapeutics would acquire the Company. United Therapeutics has commenced a tender offer to acquire all outstanding shares of the Company for a purchase price of $3.25 per share in cash at closing (an aggregate of approximately $91 million) and an additional $1.75 per share in cash upon the achievement of a clinical development milestone related to the Company’s development-stage, fully-implantable manufactured kidney product known as mirokidney™ by December 31, 2025. The offer will expire one minute after 11:59 p.m., New York City time, on December 11, 2023, unless the offer is otherwise extended or earlier terminated. The Company’s board of directors has unanimously recommended that the stockholders of the Company accept the offer and tender their shares.

This transaction is expected to close in the fourth quarter of 2023, subject to customary closing conditions, including the tender of a majority of the outstanding shares of the Company’s common stock.
