Clearthink 1 Acquisition Corp. 8-K

What Happened
Clearthink 1 Acquisition Corp. (the “Company”) announced in an 8-K (filed April 13, 2026) that holders of its public units may elect to separate those Units so the Class A ordinary shares and the rights can trade separately beginning April 16, 2026. The Class A ordinary shares are expected to trade on Nasdaq under the symbol “CTAA” and the rights under “CTAAR.” Units that are not separated will continue trading on Nasdaq under the symbol “CTAAU.” A press release describing the change was attached to the 8-K as Exhibit 99.1.

Key Details

• Separation effective date for separate trading: April 16, 2026.
• Expected Nasdaq symbols: Class A ordinary shares = CTAA; rights = CTAAR; unseparated units = CTAAU.
• Holders must have their brokers contact the transfer agent, VStock Transfer LLC, to effect the separation.
• Press release relating to the announcement filed as Exhibit 99.1 to the Form 8-K.

Why It Matters
Separating the Units lets investors buy, sell or trade the Class A shares and the rights independently, which can change liquidity, pricing and trading strategies for holders. Investors who want separate ownership of shares or rights must instruct their brokers to contact the transfer agent; otherwise their Units will remain whole and continue trading as CTAAU. This is a procedural market-structure change rather than a change to the company’s business or management.
