AUSTIN, TX and AMES, IA, March 18, 2020 – Lumos Pharma, Inc. (Lumos Pharma) and NewLink Genetics Corporation (NewLink Genetics) today announced that by an overwhelming majority, NewLink Genetics’ stockholders have voted to approve the issuance of shares in connection with the merger combining NewLink Genetics with Lumos Pharma. The completion of the merger is expected to be effective in the coming days. The combined company will assume the name, Lumos Pharma, Inc., and will trade on Nasdaq under the stock symbol “LUMO.” The combined company will focus on the development and commercialization of innovative therapeutics for rare and neglected diseases. The combined company plans to initiate a Phase 2b trial in mid-2020 evaluating its lead therapeutic candidate, LUM-201 (ibutamoren), an orally administered small molecule, in PGHD with the potential to address other rare endocrine disorders.

“We are pleased that the NewLink stockholders have voted in favor of this merger, and we are excited about the opportunity ahead for the combined company,” said Rick Hawkins, CEO of Lumos Pharma. “We are on solid financial footing and look forward to the imminent initiation of our Phase 2b trial of LUM-201 in PGHD. Our team is enthusiastic about the potential for this orally administered therapeutic to disrupt the standard-of-care injectable treatment regimen for PGHD and other indications for which recombinant growth hormone has been approved.”

Prior to the closing of the merger, NewLink plans to execute a 9-for-1 reverse split of shares of common stock, such that every 9 shares of NewLink issued and outstanding would be converted into 1 issued and outstanding share of common stock. The reverse split is expected to take effect upon opening of trading the day after the close of the merger. Adjusted for the reverse split, total shares of common stock outstanding for the combined company will be approximately 8.26 million shares.

Upon completion of the merger, the combined company’s Board of Directors will consist of Rick Hawkins, CEO, Lumos Pharma; Emmett T. Cunningham, Jr., M.D., Ph.D., Senior Managing Director, Blackstone Life Sciences group; Kevin Lalande, Co-founder and Managing Director, Santé Ventures; Lota S. Zoth, Chairman, Zymeworks and former CFO, MedImmune; Thomas A. Raffin, M.D., co-founder and partner, Telegraph Hill Partners and Professor Emeritus, Stanford School of Medicine; and Chad Johnson, General Counsel, Stine Seed Company. A seventh board member will be designated by the combined board following the completion of the merger.

The combined company’s projected cash position in excess of $80 million as of March 31, 2020 is expected to be sufficient to fund the combined company’s operations through data read-out for the Phase 2b trial of LUM-201 in PGHD. This amount excludes any anticipated non-dilutive funds from the monetization of the priority review voucher (“PRV”) issued in conjunction with the December 19, 2019 FDA approval of partnered Ebola virus vaccine V920 (rVSV∆G-ZEBOV-GP), ERVEBO^®. The combined company is entitled to 60% of the value of the PRV obtained through sale, transfer or other disposition of the PRV.

NewLink Genetics was advised by Stifel as financial advisor and Cooley LLP as legal counsel. Lumos Pharma was advised by Wilson Sonsini Goodrich & Rosati, P.C. as legal counsel.
