"and are subject to a right of repurchase by the Company which shall lapse in accordance with the vesting schedule"
Merger financial
"in connection with the merger of Hadron into a subsidiary of GigCapital7 Corp. (the "Company") (the "Merger")"
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.
business combination agreement financial
"pursuant to the exchange ratio set forth in the business combination agreement between Hadron and the Company"
A business combination agreement is a detailed contract that lays out the terms for two companies to join together—covering price, how ownership will be split, the steps needed to close the deal, and what each side promises to do or avoid before closing. For investors it matters because the agreement determines potential changes in value, control, timing, and risk exposure—think of it like the playbook for a merger that shows who wins, who pays, and what could still derail the plan.
Rule 16b-3 regulatory
"The acquisition of these shares is an exempt transaction under Rule 16b-3, promulgated by the U.S. Securities and Exchange"
Rule 16b-3 is a Securities and Exchange Commission regulation that exempts certain routine, pre-approved transactions by company insiders from automatic liability for short-term trading profits. It acts like a safe harbor: if an insider follows a formal plan or the board approves specific transactions in advance, profits from buying and selling company stock within six months are not automatically reclaimed. Investors care because the rule clarifies when insider trades are permissible and reduces uncertainty about potential clawbacks.
