MONT-SAINT-GUIBERT, Belgium, May 15, 2023 (GLOBE NEWSWIRE) -- Celyad Oncology ((Euronext &, NASDAQ:CYAD) (the "Company"), is a biotechnology company focused on innovative technologies for chimeric antigen receptor (CAR) T-cell therapies.

The Company had previously announced on April 4^th, 2023, that The Nasdaq Stock Market ("Nasdaq") notified the Company on March 31^st, 2023 that it failed to maintain the continued listing requirement under Nasdaq Listing Rule 5450(b)(1)(A) for the Nasdaq Global Market, which requires that a listed company's stockholders' equity be at least $10.0 million. Further, on April 19^th, 2023, as announced by the Company on April 24^th, 2023, the Company received a notice from Nasdaq informing the Company that the minimum closing bid price per share of its American Depositary Shares representing ordinary shares ("ADSs") was below $1.00 for a period of 30 consecutive business days and that the Company did not meet the minimum bid price requirement set forth in Nasdaq Listing Rule 5450(a)(1). On May 5^th, 2023, the Company announced that its Board of Directors approved the voluntary delisting of its ADSs from the Nasdaq Global Market.

On May 10^th, 2023, the Company received a notification letter from Nasdaq (the "Notice"), advising the Company that its ADSs are scheduled for delisting from The Nasdaq Global Market and will be suspended at the opening of U.S. business on May 19^th, 2023. The Notice stated that Nasdaq has determined that the Company did not provide a definitive plan evidencing its ability to achieve near term compliance with the continued listing requirements or sustain such compliance over an extended period of time. The Company does not intend to appeal Nasdaq's determination and, therefore, it is expected that the Company's ADSs will be delisted from the Nasdaq Global Market on May 19^th, 2023. A Form 25-NSE will be filed with the U.S. Securities and Exchange Commission (the "SEC"), which will remove the Company's ADSs from listing on Nasdaq. The Company will continue to be listed on Euronext Brussels. Whether or not the Company's ADSs will be traded on the over-the-counter market thereafter will depend on the actions of shareholders and independent third parties, without the Company's involvement.

The Company's reporting obligations under applicable U.S. federal securities laws are expected to continue after the delisting from the Nasdaq Global Market.

Additional Information for ADS Holders

On May 5^th, 2023, the Company announced that the Board of Directors approved the termination of its American Depositary Receipt ("ADR") facility and that it will instruct Citibank, N.A., as depositary, to issue the notice of termination of its ADR facility to holders of ADSs according to the requirements under the depositary agreement. At this time, such notice has not been issued and the Company's ADR facility remains in place until further notice. The Company intends to release further information on its ADR facility at a later date.

The Company reserves the right, for any reason, to otherwise change its plans in respect of termination of the ADR facility in any way.
