Effective Time regulatory
"Effective as of July 27, 2026 (the Effective Time), a subsidiary merged with Yarrow"
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.
Merger regulatory
"A wholly owned subsidiary of VYNE Therapeutics Inc. merged with and into Yarrow"
A merger is when two companies combine into a single business, with ownership and control reorganized so they operate as one entity. For investors it matters because mergers can change the value and risk of holdings—shares may be exchanged, diluted, or rise if the combined company saves costs or gains market power, and the deal often depends on regulatory approval and successful integration like two households joining resources and routines.
