Twenty One Capital, a Bitcoin reserve company controlled by Tether, has received a non-compliance notice from the New York Stock Exchange (NYSE) due to a lack of independent directors on its Audit Committee. The company must address this issue by June 6 to avoid receiving a "BC" (Below Compliance) designation starting June 9. This situation arose after Tether acquired all Class A shares from SoftBank, leading to the resignation of two directors, including an Audit Committee member. The company, which holds 43,514 BTC valued at approximately $3.1 billion, has seen its stock plummet over 83% year-to-date, with its market capitalization falling below $2.5 billion. Twenty One Capital has pledged to appoint a new independent Audit Committee member soon but has not disclosed further details. The compliance crisis adds to the company's challenges amid leadership instability and unmet business commitments.
