Agreement and Plan of Merger regulatory

"Pursuant to that certain Agreement and Plan of Merger ("Merger Agreement"), dated May 31, 2026"

An Agreement and Plan of Merger is a formal document where two companies agree to combine into one, outlining how the process will happen. It’s like a step-by-step plan for merging, and it matters because it shows both sides have agreed on the details before the official transition takes place.

Effective Time regulatory

"immediately prior to the effective time of the transactions contemplated thereby (the "Effective Time")"

The exact clock time when a regulatory filing, approval, or corporate action formally becomes legally active; from that moment the change is binding and can be acted on. Investors care because the effective time marks when ownership, rights, trading rules, or new securities take effect — like a light switch turning on a contract or transaction — which determines when risks, benefits and market reactions begin.

Parent Ordinary Shares financial

"0.5537 ordinary shares, par value $0.001 per share, of Parent ("Parent Ordinary Shares")"

maximum cash election amount financial

"subject to a maximum cash election amount; and (B) 0.2392 Parent Ordinary Shares."
