WESTON, Fla. and BRIDGEWATER, N.J., July 20, 2022/PRNewswire/ -- ZyVersa Therapeutics, Inc. ("ZyVersa"), a clinical stage specialty biopharmaceutical company leveraging advanced, proprietary technologies to develop product candidates that address unmet medical needs in the areas of renal and inflammatory diseases, and Larkspur Health Acquisition Corp. (NASDAQ: LSPR or "Larkspur"), a blank-check special purpose acquisition company, announced today that they have entered into a definitive business combination agreement (the "Business Combination Agreement"). The business combination transaction is expected to provide ZyVersa with access to the public equity market, which the parties believe will escalate development of ZyVersa's renal and inflammasome product candidate pipelines. Upon the business combination transaction closing, which is expected to occur in the fourth quarter of 2022, the combined company is expected to be named ZyVersa Therapeutics, Inc., which will continue to operate under the ZyVersa management team, led by Stephen C. Glover, Co-Founder, Chief Executive Officer, and Chairman. The combined company's common stock is anticipated to be listed on NASDAQ under ticker symbol "ZVSA."

"We are delighted to partner with Larkspur in this business combination. Their management and board have vast experience as investors and operating executives in the biopharmaceutical industry," stated Mr. Glover. "This merger and entry into the public markets will enable us to escalate development of our pipeline drug candidates for targeted patients with renal and inflammatory diseases, who have the need for disease-modifying drugs that are well tolerated and safe. We believe our drug candidates in development for these patients have potential to meet these needs and help drive improved health outcomes," added Mr. Glover.

"ZyVersa's management team has deep scientific and operational experience, and the company has two exciting assets, IC 100 for inflammatory diseases and VAR 200 for renal diseases," said Daniel J. O'Connor, Chairman and Chief Executive Officer of Larkspur. "IC 100, an inflammasome ASC inhibitor, blocks upstream intracellular initiation of the inflammatory cascade and extracellular perpetuation of inflammation, leading to potential for application in numerous, diverse inflammatory conditions. VAR 200, 2-hydroxypropyl-beta-cyclodextrin, is a cholesterol efflux mediator intended to reduce renal lipid accumulation that contributes to glomerular diseases and their progression. VAR 200's lead indication is orphan focal segmental glomerulosclerosis. It also has potential to treat orphan Alport syndrome and diabetic kidney disease. ZyVersa's CEO, Mr. Glover has co-founded and led multiple biopharma companies. Prior to co-founding ZyVersa, he was Co-founder and Chief Business Officer of Coherus BioSciences, a late-stage commercial biologics platform company focused on delivering biosimilar therapeutics which went public in 2014. Previously, Mr. Glover was President of Insmed Therapeutic Proteins and EVP and Chief Business Officer of Insmed Incorporated, where he was responsible for creating the company's biosimilar business unit and divestiture of that business to Merck. He also led the strategic review process that resulted in the merger of Insmed and Transave," added Mr. O'Connor. "Mr. Glover clearly excels in licensing, M&A, raising capital, and taking companies public. His current management team consists of successful leaders in drug development, manufacturing, and commercialization from his prior companies. We believe that ZyVersa is well positioned to create significant value for stockholders," concluded Mr. O'Connor.

The combined company will have an estimated pro forma enterprise valuation of approximately $108.92 million. Cash proceeds from the transactions contemplated by the Business Combination Agreement (the "Transactions") are expected to consist of up to approximately $77.67 million of cash held in Larkspur's trust account (before any redemptions by Larkspur's public stockholders and the payment of certain expenses) and approximately $7.00 million attributable to a private investment anchored by new institutional investors (the "PIPE Investment"). Proceeds from the PIPE Investment are expected to be used as working capital and to advance the clinical evaluation of VAR 200 and progress IC 100 into the clinic. The PIPE Investment expected to close in connection with the business combination is conditioned upon ZyVersa obtaining an additional interim financing, and also subject to the satisfaction of other customary closing conditions and a NASDAQ listing. After the closing of the Transactions and assuming no redemptions by Larkspur's public stockholders, existing ZyVersa shareholders will retain 100% of their equity ownership and will own approximately 44.20% of the pro forma combined company.

The Transactions, which have been unanimously approved by the boards of directors of both ZyVersa and Larkspur, are subject to, among other customary closing conditions, approval by shareholders of Larkspur, and shareholders of ZyVersa.
