Key Terms

Business Combination Agreement, Voting, Support and Lock-Up Agreement, Earnout Shares, VWAP, +1 more

5 terms

Business Combination Agreement financial

"The Business Combination Agreement provides for, among other things, the Initial Merger and the Acquisition Merger"

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.

Voting, Support and Lock-Up Agreement financial

"the Reporting Person is party to that certain Voting, Support and Lock-Up Agreement"

Earnout Shares financial

"an aggregate of up to 5,000,000 additional PubCo Ordinary Shares (the "Earnout Shares")"

Earnout shares are company stock promised to sellers as part of an acquisition that only becomes payable if the acquired business hits agreed future performance targets, like revenue or profit goals. They matter to investors because they can increase the number of shares outstanding (dilution), tie seller incentives to future success, and create uncertainty about the actual cost of the deal and future ownership unless the performance conditions are clearly understood.

VWAP financial

"the volume-weighted average price ("VWAP") of the PubCo Ordinary Shares equals or exceeds $11.00"

VWAP, or Volume-Weighted Average Price, is a way to find the average price of a stock throughout the trading day, giving more importance to times when more shares are traded. It helps traders see the typical price and decide whether a stock is expensive or cheap compared to its average, similar to finding the average speed during a trip by giving more weight to times when you traveled faster or slower.

Schedule 13D regulatory

"If the filing person has previously filed a statement on Schedule 13G to report the acquisition"

A Schedule 13D is a legal document that investors file with regulators when they buy a large enough stake in a company to potentially influence its management or decisions. It provides details about the investor’s intention, ownership stake, and plans, helping other investors understand who is gaining control and what their motives might be.
