Exhibit		Description

99.1		Press release issued by the registrant on March 24, 2020

Mont-Saint-Guibert, Belgium—Celyad (Euronext Brussels and Paris, and NASDAQ: CYAD), a clinical-stage biopharmaceutical company focused on the development of CAR-T cell therapies, today announced its consolidated financial results for fiscal year 2019 ended December 31, 2019 and provided a business update.

“This is an exciting time for us as we advance Celyad as an innovative leader in the industry which is focused on developing CAR-T therapies for cancer patients. The progress we made throughout 2019 positions Celyad with a balanced pipeline of clinical and preclinical CAR-T candidates as we enter the new decade with several milestones on the horizon,” commented Filippo Petti, Chief Executive Officer of Celyad. “We now have two autologous clinical CAR-T candidates in development for the treatment of r/r AML and MDS and a portfolio of promising allogeneic CAR-T candidates, led by CYAD-101, for the treatment of mCRC. We look forward to providing key updates on our clinical progress throughout 2020. Over the past year, we also progressed our shRNA platform for next-generation CAR-T candidates, including our preclinical allogeneic BCMA-targeted candidate, CYAD-211. I am extremely proud of our team’s achievements over the past twelve months and look forward to a productive 2020.”
