A cash merger is an acquisition in which the buyer pays the target company’s shareholders entirely in cash for their shares rather than issuing stock or a mix of stock and cash. If you own shares in a company being bought this way, you’ll receive a fixed dollar amount per share at closing, owe capital gains tax on any profit, and have a narrow legal path to challenge the price if you think it’s too low. The rest comes down to timing and paperwork.
How You Get Paid at Closing
When the deal closes, every outstanding share of the target company converts into the right to receive the stated cash price. You no longer own stock. You own a claim to a cash payment.
If your shares sit in a brokerage account, the process is largely automatic. The paying agent, usually a bank or trust company appointed by the buyer, sends the funds to your broker, and your broker credits your account within a few business days after closing.
If you hold physical stock certificates or shares registered directly in your name, you’ll get a letter of transmittal from the paying agent. Complete it, sign a W-9, gather your certificates, and submit the package. The paying agent verifies the documents and issues payment by check or wire. Lost a certificate? You’ll need to file an affidavit of loss and may have to buy a surety bond before you get paid.
Most merger agreements set a deadline for submitting the letter of transmittal. Miss it and your funds eventually get turned over to a state unclaimed property office, which turns a routine payout into a recovery project.
What You’ll Owe in Taxes
Receiving cash for your shares is a taxable event. You report the difference between the cash you receive and your cost basis, which is generally what you originally paid for the shares, adjusted for stock splits and reinvested dividends. That difference is a capital gain or loss.1Internal Revenue Service. Topic No. 409, Capital Gains and Losses
How much tax you pay depends on how long you held the shares. More than a year, and the gain is long-term, taxed at preferential rates. A year or less, and it’s short-term, taxed at ordinary income rates that can reach 37%.1Internal Revenue Service. Topic No. 409, Capital Gains and Losses
For 2026, the long-term capital gains brackets are:
- 0% on taxable income up to $49,450 for single filers or $98,900 for married couples filing jointly
- 15% on taxable income up to $545,500 for single filers or $613,700 for married couples filing jointly
- 20% on taxable income above those thresholds
Higher earners also face a 3.8% net investment income tax on capital gains once modified adjusted gross income tops $200,000 for single filers or $250,000 for joint filers.2Internal Revenue Service. Net Investment Income Tax That surtax pushes the top long-term rate to 23.8%.
One point people miss: shares held in an IRA or other tax-advantaged account produce no immediate tax when they’re cashed out. The tax hit applies only to shares in taxable accounts. If you own the same stock in both, only the taxable-account position generates a reportable gain.
If You Think the Price Is Too Low
Shareholders who believe the merger price undervalues their shares can invoke appraisal rights. Under state corporate law, a dissenting shareholder can ask a court to independently determine the fair value of their shares and order the company to pay that amount instead of the merger price. The right exists because a majority vote can otherwise force the deal on holders who disagree with the price.
The procedure is unforgiving. You must deliver a written demand to the company before the shareholder vote, and you must not vote in favor of the merger. Voting against the deal alone is not enough. Vote yes, or miss the written-demand deadline, and the right is gone. After closing, you have a limited window to file a petition in court to start the appraisal proceeding.
It’s also not risk-free. A court can find that fair value equals or falls below the merger price, leaving you worse off after litigation costs. Proceedings can run for years while your cash sits tied up. For most retail investors with small positions, the expense and uncertainty make appraisal impractical. The shareholders who actually pursue it tend to be hedge funds and institutions with enough at stake to justify the fight.
Your Vote and How the Deal Gets Approved
Cash mergers reach closing through one of two structures, and which one applies affects whether you vote at all.
In a one-step merger, the buyer and the target’s board sign a merger agreement, the company files a proxy statement, and shareholders vote at a special meeting. The proxy lays out the merger terms, the board’s reasoning, any fairness opinion from a financial advisor, potential conflicts among directors and officers, and the negotiation history.3U.S. Securities and Exchange Commission. Exchange Act Reporting and Registration Approval usually requires a simple majority of outstanding shares, though some corporate charters or state statutes set the bar higher, such as two-thirds.
In a two-step deal, the buyer first launches a tender offer directly to shareholders at the stated price. If enough shareholders tender, the buyer takes control and completes a back-end merger to cash out the rest at the same price. When the buyer clears 90% in the tender offer, most state statutes allow a short-form merger that skips the shareholder vote entirely.
Either way, the buyer’s shareholders usually don’t vote on a cash deal, because paying cash doesn’t dilute existing buyer shares. Institutional holders like mutual funds and pension funds often control enough of the target’s stock to swing the vote, and proxy advisory firms that recommend how those institutions should vote can effectively decide close contests. Realistically, an individual retail holder’s vote rarely changes the outcome.
If You’re Also an Employee
Employees who own vested stock get cashed out the same way as any other shareholder. Unvested stock options and restricted stock are treated separately, and the merger agreement will spell out one of three outcomes: unvested awards vest immediately at closing and convert to cash, the buyer assumes the grants and replaces them with equivalent equity in the acquiring company, or the awards are canceled. Check the merger agreement and any employee communications for the specific treatment before making assumptions.
Compensation and benefits protection is a separate question. Merger agreements sometimes require the buyer to maintain comparable pay and benefits for a set period after closing, but these terms vary and aren’t guaranteed. If the buyer plans significant post-closing layoffs, the federal Worker Adjustment and Retraining Notification Act may require 60 days’ advance written notice. WARN applies to employers with 100 or more full-time workers when a plant closing or mass layoff affects 50 or more employees at a single site. The seller handles WARN obligations before closing, and the buyer takes them over afterward.4U.S. Department of Labor. Employer’s Guide to Advance Notice of Closings and Layoffs Some states have their own versions with lower thresholds or longer notice periods.
How Long the Deal Takes and What Can Kill It
Most cash mergers close three to six months after signing, with the bulk of that time consumed by regulatory review and proxy preparation. Deals above certain size thresholds require pre-merger notification under the Hart-Scott-Rodino Antitrust Improvements Act. In 2026, a transaction where the acquirer would hold more than $133.9 million in the target’s voting securities or assets triggers an HSR filing with the FTC and the Justice Department, and neither side can close until the waiting period expires.5Federal Trade Commission. FTC Announces 2026 Update of Jurisdictional and Fee Thresholds for Premerger Notification Filings6Office of the Law Revision Counsel. 15 USC 18a – Premerger Notification and Waiting Period
The standard waiting period is 30 days from receipt of both filings, or 15 days for cash tender offers. If regulators have concerns, they can issue a second request, which stops the clock until both parties comply and then restarts a new period.7Federal Trade Commission. Getting in Sync – HSR Timing Considerations A second request is a serious signal, and compliance typically takes months.
Financing is the other thing that can derail a deal. Some buyers pay from cash on hand; most secure committed debt financing from banks before signing, with a commitment letter promising the funds at closing. The merger agreement usually spells out what happens if the lender walks, and that outcome typically involves the buyer paying the target a reverse termination fee, commonly 3% to 6% of equity value. As a target shareholder, you don’t bear that financing risk directly. If the deal fails, you keep your shares and the target collects the fee.
