Stock Purchase Agreement financial

"pursuant to the Stock Purchase Agreement"

A stock purchase agreement is a legal contract that sets the terms for buying or selling shares, specifying the price, number of shares, how payment is made, and any conditions or promises each side must meet. It matters to investors because it defines who owns what, when ownership changes, and what protections or obligations attach to the deal—think of it as a detailed receipt plus the house rules that determine the financial risks and benefits of the transaction.
