The exact result depends on the transaction: a fixed stock exchange ratio determines the number of new shares, not necessarily their dollar value. Check the definitive proxy statement or proxy statement/prospectus for the terms, deadlines, and any action required from you.
What happens to your shares in a merger?
The merger agreement sets out what happens to eligible shares at the transaction’s effective time. Depending on the deal, they may convert into cash, a fixed number of shares in the acquiring company, a combination of cash and shares, or consideration calculated using a formula. There can be exclusions, special rights, or separate treatment for options and other equity awards, so the headline description may not cover every security or holder.

For example, one SEC-filed all-cash merger proxy says eligible shares convert into $9.50 cash per share, without interest, at the effective time. That is a term of that particular transaction, not a typical or guaranteed merger payout. See the all-cash merger proxy.
How cash, stock, and mixed consideration differ
| Consideration | What the deal specifies | What can change for you |
|---|---|---|
| Cash | A stated cash amount per eligible share, subject to the deal’s terms and closing. | The deal documents determine eligibility, timing, and any tax consequences. The cited all-cash proxy describes $9.50 per eligible share without interest at the effective time; that figure applies only to that transaction. Proxy example. |
| Stock | An exchange ratio: the number of acquirer shares received for each eligible target share. | The number of shares can be fixed while their market value changes with the acquirer’s share price before closing. |
| Cash and stock | A stated combination of cash and acquirer shares, potentially subject to adjustments or conditions. | Both the formula and the market price of the stock component can affect the value ultimately received. |
In the proposed FOX–Roku transaction, the joint proxy statement/prospectus describes consideration of 0.9693 FOX Class A shares plus $96 cash for each eligible Roku share if the mergers close. It also provides cash in place of issuing fractional FOX shares. Those are transaction-specific proposed terms, not a general rule. FOX–Roku joint proxy statement/prospectus.

Why the stated deal value can move
For stock consideration, distinguish the exchange ratio from the implied dollar value. If the ratio is fixed, it sets how many acquirer shares correspond to each target share; it does not lock in the value of those shares. The FOX–Roku filing states that its ratio would not change with FOX’s share price and that the value of the stock-and-cash consideration would fluctuate with FOX’s market price until consummation. FOX–Roku filing.
The filing gives dated illustrations, not current prices: the proposed consideration implied $162.20 per Roku share using FOX’s June 11, 2026 closing price, and $161.16 using its August 27, 2026 closing price. Each calculation reflects the stated FOX price on that date; neither figure is a market-wide merger statistic or a guaranteed amount at closing.
Rank #2
Some transactions use adjustable ratios rather than a single fixed ratio. An SEC Form 8-K describing the Iridium–Rocket Lab transaction specifies $27 cash plus stock, with a 0.4000 ratio when the measured Rocket Lab price is at or below $67.50, a 0.2400 ratio at or above $112.50, and a formula between those thresholds. The thresholds and formula belong to that transaction alone. Iridium–Rocket Lab Form 8-K.
What to check in the deal documents
Use the definitive proxy statement or proxy statement/prospectus, along with the merger agreement and any exchange-agent or broker instructions. The filed transaction materials explain the governing mechanics; announcement summaries may omit details that matter to a particular holder.
- Consideration: Identify exactly what each eligible share converts into and whether the amount is cash, stock, mixed, or formula-based.
- Ratio and adjustments: Check whether the exchange ratio is fixed, floating, or subject to thresholds, collars, or other adjustment provisions.
- Closing status and conditions: Determine whether the deal is proposed, shareholder-approved, awaiting other conditions, or closed. Announced terms are not the same as delivered consideration.
- Fractional shares and awards: Find out how fractions are settled and whether options, restricted stock, or other awards have separate treatment.
- Voting and procedures: Review any vote, election, certificate, book-entry, exchange, or special-right instructions, including their deadlines.
- Risks and timing: Read the stated closing conditions, expected timing, and transaction risks; a deal can remain incomplete until its conditions are satisfied.
- Tax discussion: Read the transaction-specific tax section, but do not treat it as personal tax advice.
What to do as a shareholder
- Find the definitive filing. Search the issuer’s investor-relations materials or SEC filings for the definitive proxy statement or proxy statement/prospectus. Read its summary, “The Merger,” consideration, conditions, risks, tax, vote, and exchange-agent sections.
- Confirm the deal’s stage. Check whether it has only been announced, has received required approvals, is still subject to conditions, or has closed.
- Work out the stated consideration. For stock or mixed consideration, note the ratio and any adjustment formula. If estimating value, use the acquirer’s market price for a clearly stated date and show the calculation assumptions.
- Follow the instructions that apply to your holding. Check notices from the issuer, transfer agent, exchange agent, and broker. Some arrangements convert automatically; others may require steps for certificates, book-entry shares, elections, or special rights. Do not assume there is one universal action or deadline.
- Keep transaction records. Retain relevant statements and deal notices, particularly if you receive cash, acquirer shares, or cash for a fractional share.
Taxes and shareholder rights depend on the details
Tax treatment depends on the transaction’s structure and the holder’s circumstances. One all-cash proxy says the exchange is generally taxable for U.S. federal income tax purposes and advises holders to consult their own tax advisers about federal, state, local, and non-U.S. consequences. Another merger filing discusses different consequences for holders receiving cash and shares, including basis and holding-period issues. All-cash proxy and mixed-consideration merger filing.
The Iridium–Rocket Lab filing describes an intended U.S. federal tax-free reorganization only if specified conditions concerning the value relationship between stock and cash are met. That conditional statement applies to that transaction and does not establish tax-free treatment for another mixed merger. Form 8-K.
Appraisal or dissenters’ rights, where available, depend on the governing law, transaction facts, eligibility, and compliance with procedural deadlines. The applicable deal documents and law determine whether a particular shareholder qualifies; do not infer eligibility or whether exercising a right is preferable from general examples. For personal tax or legal circumstances, consult a qualified adviser.
