What happens to listed call options in a cash buyout?

This page is about listed call options you trade at a broker, not employee stock options. When an all-cash buyout closes, listed options usually expire early and settle for their intrinsic value in cash. Time value is gone, so a call can lose money even when the deal price is above the strike.

The short answer

This page is about listed Call option contracts, the kind you buy and sell on an exchange. Employee stock options from your job follow your company's plan and the merger agreement instead. Check those documents or your plan administrator.

For listed options, an all-cash buyout works like this:

• When the deal closes, each share turns into a fixed amount of cash.
• A call on those shares now delivers cash, not stock.
• The OCC usually moves the expiration date up to around the closing. This is called Accelerated expiration.
• Each call settles for its Intrinsic value: the deal price minus the strike, times 100. If the strike is at or above the deal price, the call settles at zero.

There is no time value left. Whatever you paid above intrinsic value is gone. For the full list of events, see my hub on corporate actions and your options.

Why the time value disappears

An option's price has two parts. Intrinsic value is what it's worth if exercised right now. Time value is what people pay for the chance the stock moves further before expiry.

A cash deal kills that chance. Once the deal is announced, the stock tends to trade in a tight band just under the deal price. Once the deal closes, there is no stock left to move at all. The option has nothing left to wait for, so the OCC ends it early.

That's why a call with months left can lose most of its time value in one morning. See how options are priced for the two parts in more detail.

A worked example: the buyout came, and the call still lost (hypothetical)

This is an illustration, not a trade idea. XYZ is a made-up stock.

• XYZ trades at $48.
• You buy one call, $50 strike, six months out, for $5.00. You pay $500. All of it is time value, because the strike is above the price.
• Two weeks later, a buyer offers $54 a share in cash. XYZ jumps to $53.50.

That sounds like a win. The deal is $4 above your strike. But when the deal closes, your call settles for ($54 − $50) × 100 = $400. You paid $500.

Result: −$100. The buyout was above your strike and you still lost money, because the time value you paid for never came back.

Every deal price, for the buyer and the seller

Same call, $50 strike, $500 premium.

The call buyer needs the deal price to beat the strike by more than the premium paid. Here, that is $55. Anything less is a loss.

The seller is on the other side of every row. If you sold this call against shares you own, see a covered call when the stock gets bought out. The shares change that math.

What you can do before the deal closes

Between the announcement and the close, which can take weeks or months, the call still trades. You have three choices.

1. Sell the call. Its price will sit near its intrinsic value, plus a little for the chance of a higher bid. In the example, maybe around $3.80, or $380, with XYZ at $53.50. That locks in −$120.
2. Hold until the close. You get the $400 settlement if the deal closes at $54. If the deal breaks, XYZ usually falls back toward $48 and the call could be worth far less than $380.
3. Exercise early. You'd pay $5,000 for 100 shares, then receive $5,400 when the deal closes. That's the same $400, but it ties up $5,000 for weeks. Selling the call usually gets you as much or more.

Holding gains you $20 if the deal closes. It risks another $330 if it doesn't. That's the trade-off in one row. The $50 value in the deal-break row is a rough guess for illustration.

What about puts?

Puts work the same way. When the deal closes, a put settles for the strike minus the deal price, if positive. A put with a strike below the deal price settles at zero.

That matters if you sell puts, as in the wheel strategy. A short put with a strike below the deal price usually ends worthless, and you keep the premium. The risk is the deal failing first. See what happens to a short put when the stock gets acquired.

What if the deal is stock, or cash and stock?

Then there's usually no early expiration. The contract is adjusted to deliver the buyer's shares, or a mix of shares and cash, and keeps trading until its normal expiry. See options in a cash-and-stock merger.

The OCC publishes an information memo for each deal. It states the exact cash amount, the dates and what happens to each contract. Your broker can point you to it. See how to read an OCC memo.

The rule for next time

• Know what you're paying for. Time value only pays off if the stock moves past your break-even before expiry. A buyout can end that wait early.
• Check the break-even, not the strike. The strike plus the premium is the number the deal must beat.
• After an announcement, compare selling now with holding. The extra you'd earn by holding to the close is usually small next to what a broken deal would cost.
