Calculate Your Payout in a Fixed-Dollar All-Stock Deal

When an all-stock deal fixes a dollar value, your payout is a share count set near the end. The trap is assuming the share count is known before closing. The rule is to find whether the deal terms fix dollars or shares, then locate the price window that turns dollars into shares.

The price basis tells you what is fixed

Read the merger agreement, the contract that sets the deal terms, not the press release. On September 26, 2026, AMD agreed to buy World Labs Technologies, and the World Labs merger agreement provides that the consideration is AMD common stock with a value of about $8.2 billion. The terms leave the AMD share count undetermined rather than setting a fixed number of shares. If you hold equity, the acquirer's public filing is usually the cleanest place to start. AMD made the World Labs acquisition public on September 28, 2026, and submitted a Form 8-K to the SEC that day.

Look for language that sets a total purchase price in dollars and then says the share count will be calculated. If the agreement instead sets a fixed exchange ratio, a set number of acquirer shares per target share, a rising AMD price increases the dollar value of the payout, while the World Labs fixed-dollar formula changes the number of shares instead. You have found the variable when you can name it.

The VWAP window sets your share count

Locate the price basis. The number of AMD shares to be issued is not fixed; AMD will determine the World Labs share count by referencing its stock's daily volume-weighted average price, or VWAP, across the 10 consecutive trading days that end on the second trading day before closing. That window sets the price used to turn dollars into shares, so the final share count is unknown until near the end. You do not need to compute it yourself. You need to know which days count and when the window ends.

The common mistake is to use the announcement-day price or today's price. Use the window in the agreement, not the date the deal became public. If the closing date moves, the window moves with it. That can change the average price even if the deal terms do not. The test is whether you can name the trading days that set the price, not just the announcement date.

A price range beats one number

Build a small table with price scenarios. Using AMD's October 2, 2026 closing price of $633.91, the $8.2 billion purchase price translates to about 12.9 million shares, which is roughly 0.8% of the 1,632,475,042 shares outstanding as of July 29, 2026. The consideration, or deal value, is calculated from approximately $8.2 billion and AMD's 10-day VWAP, and a higher AMD stock price in that window reduces the number of AMD shares issued.

• Current: use the acquirer's price near the VWAP window, not the announcement price.
• Higher: assume a stronger stock price and calculate fewer shares.
• Lower: assume a weaker stock price and calculate more shares.

To model it, divide the fixed dollar value by the VWAP to get total shares. Your share count equals your ownership percentage times the total shares. If you own a small percentage of the company, your slice is that percentage of the total deal value. The output is a range of share counts and dollar values, not one number.

Option treatment changes the final payout

Apply your ownership percentage and option terms to the total deal value. Check whether your options convert into acquirer options, are cashed out at the deal value, or vest early if the deal closes. In a merger paid in stock, equity options are usually addressed in the merger agreement or the option plan. Check the treatment before you accept an offer or model a payout.

You are ready when you can state your slice of the total deal value and the form it takes. The deal is targeted for completion by the end of 2026, subject to regulatory sign-off and standard closing conditions. Your payout date may move with the closing date. Your payout at closing is your stake times the total deal value, adjusted for option terms.
