Keystone Acquisition Corp. 8-K

What Happened

• Keystone Acquisition Corp (KEYY) announced on June 18, 2026 (in an 8‑K and press release, Exhibit 99.1) that holders of its publicly traded Units may elect to separately trade the Class A ordinary shares and warrants included in each Unit commencing on or about June 22, 2026.
• Each Unit consists of one Class A ordinary share and one-half of one redeemable warrant to purchase one Class A ordinary share. Unseparated Units will continue trading on the Nasdaq Global Market under the symbol "KEYYU"; separated Class A shares and warrants will trade under "KEYY" and "KEYYW," respectively.

Key Details

• Separation effective on or about June 22, 2026 (press release dated June 18, 2026).
• Unit composition: 1 Class A ordinary share + 0.5 redeemable warrant.
• No fractional warrants will be issued upon separation; only whole warrants will trade.
• Holders must instruct their brokers to contact Efficiency INC., the Company’s transfer agent, to effect the separation.

Why It Matters

• This change gives investors the option to trade the underlying Class A shares and warrants separately, allowing more targeted trading strategies (shares vs. warrants) and potentially different price discovery for each security.
• Investors holding Units should contact their brokers if they want to separate their holdings; note the practical implication that fractional warrants won’t be issued, which may affect how many whole warrants a particular holder can receive.
