Exercise Relates to Remaining Tranche 1 Warrants

Concert Pharmaceuticals, Inc. (NASDAQ: CNCE) today announced that BVF Partners L.P. and RA Capital Management have exercised their remaining tranche 1 warrants issued in connection with the Company’s November 2021 financing, resulting in proceeds of $20.9 million to the Company. Concert has the potential to receive an additional $49.2 million if the tranche 2 warrants issued to BVF and RA Capital in connection with the same financing are exercised in full by their October 31, 2022 expiration date. If the tranche 2 warrants are fully exercised, under its current operating plan, Concert would expect its cash, cash equivalents and investments to fund the Company beyond the anticipated submission of its New Drug Application (NDA) for CTP-543, which is expected in the first half of 2023.

The exercise period of the tranche 1 and tranche 2 warrants was tied to the clinical success of the Company’s CTP-543 THRIVE-AA1 and THRIVE-AA2 Phase 3 trials for alopecia areata. Concert reported positive topline results from the THRIVE-AA1 and THRIVE-AA2 trials in May 2022 and August 2022, respectively. In June 2022, Concert received $18.9 million from the partial exercise of the tranche 1 warrants issued to BVF and RA Capital.

Concert Pharmaceuticals is a late-stage clinical biopharmaceutical company that is developing small molecule drugs that it discovered through the application of its DCE Platform^® (deuterated chemical entity platform). Selective incorporation of deuterium into known molecules has the potential, on a case-by-case basis, to provide better pharmacokinetic or metabolic properties, thereby enhancing their clinical safety, tolerability or efficacy. Concert’s lead product candidate CTP-543 is being developed for the treatment of alopecia areata, a serious autoimmune dermatological condition. Concert is also assessing a number of earlier-stage pipeline candidates. For more information please visit www.concertpharma.com or follow us on Twitter at @ConcertPharma or on LinkedIn.
