Covered Call When Your Stock Gets a Takeover Bid: What Happens Next

The Short Answer: Your Call Gets Complicated Fast

When a stock you own gets a takeover bid, your covered call position does not simply disappear. If the bid price lands above your strike price, your call is now deep in-the-money, early assignment becomes very likely, and you will almost certainly sell your shares at the strike — not at the higher takeover price. That gap between your strike and the deal price is money you will not collect.

This is one of the sharpest real-world risks of selling covered calls, and it happens faster than most traders expect. Understanding the mechanics before it hits your portfolio is the only way to protect yourself.

What Actually Happens to Your Option When a Bid Is Announced

The moment a takeover bid is announced, the underlying stock usually gaps up toward the offer price. Your short call, which was probably out-of-the-money or near-the-money when you sold it, is now deep in-the-money.

A deep in-the-money call has almost no time value left — it trades nearly dollar-for-dollar with the stock. The buyer of your call now holds an option worth exercising immediately, because waiting gains them nothing. According to the Options Industry Council (OIC), American-style equity options can be exercised at any time before expiration, and counterparties routinely exercise deep in-the-money calls early to capture the economic value.

Your broker will notify you of assignment, your 100 shares per contract will be called away at your strike price, and you keep the premium you collected when you sold the call. That premium is now the only extra compensation you receive above your strike.

Worked Example: AAPL Gets a Takeover Bid

Say you own 100 shares of Apple (AAPL) bought at $185. Three weeks ago you sold one covered call with a $195 strike expiring in 30 days and collected $2.10 per share ($210 total premium).

Today, a hypothetical acquirer announces a cash tender offer at $220 per share. AAPL gaps up to $218 in pre-market trading.

Here is where you stand:

• Your $195 call is now $23 in-the-money. • The call's market price jumps to roughly $23.00–$23.50 (almost pure intrinsic value, minimal time value left). • The call buyer exercises early. You are assigned. Your 100 shares are sold at $195. • Your total proceeds: $195 (strike) + $2.10 (premium already collected) = $197.10 per share. • The deal price is $220. You missed $22.90 per share — $2,290 on 100 shares.

You still made a profit from your $185 cost basis ($197.10 − $185 = $12.10/share, or $1,210 total). But you left $2,290 on the table compared to an unhedged shareholder who simply held the stock.

This is the covered call's fundamental trade-off in a takeover: you capped your upside before the upside arrived.

Can You Buy Back the Call Before Assignment?

Yes — but it will cost you. To close your short call position before assignment, you buy it back at the current market price. In the AAPL example above, that means paying roughly $23.00–$23.50 to close a call you sold for $2.10. You would take a loss of about $20.90–$21.40 per share on the option trade itself, but you would then own the stock free and clear and could tender your shares at $220.

Net result of buying back: $220 (tender price) − $21.40 (buyback cost) + $2.10 (original premium) = $200.70 per share. That is better than being assigned at $197.10, but it requires fast action and available capital to fund the buyback.

The window is narrow. Once you receive an assignment notice — which can arrive overnight — the shares are already gone. FINRA rules require brokers to process assignment notices promptly, so do not assume you have until market open to act.

Check your broker's cut-off time for same-day option orders. Many brokers stop accepting option orders 15–30 minutes before the 4:00 PM ET close, and assignment can happen after hours.

Stock-for-Stock Deals: A Different Set of Problems

Not every takeover is a clean cash deal. In a stock-for-stock merger, shareholders receive shares of the acquiring company instead of cash. This creates a wrinkle for your covered call.

When the underlying security changes — through a merger, stock split, or special dividend — the Options Clearing Corporation (OCC) adjusts the option contract terms. The OCC, which clears all US listed options, publishes adjustment memos that specify exactly what the new deliverable is. Your $195 AAPL call might be adjusted to deliver a combination of acquirer shares and/or cash that equals the economic equivalent of the original contract.

These adjusted contracts often become illiquid quickly. The bid-ask spread widens, and closing the position at a fair price gets harder. If you are holding a covered call through a stock-for-stock deal, monitor OCC adjustment notices through your broker or directly at the OCC's website and act before liquidity dries up.

Tax Consequences You Need to Know

Assignment in a takeover is a taxable event. When your shares are called away, the IRS treats it as a sale of the underlying stock. Your cost basis is your original purchase price, your proceeds are the strike price, and the premium you collected is added to those proceeds — exactly as in any covered call assignment.

If you held the shares for more than one year before assignment, the gain on the stock qualifies for long-term capital gains rates. However, the IRS has specific rules under Section 1092 about how covered calls interact with holding periods. Selling an in-the-money covered call can suspend your holding period clock. If your call was in-the-money when you sold it, consult a tax professional before assuming long-term treatment applies.

For Canadian investors, the CRA treats option premiums as capital gains or income depending on your trading pattern and intent. CRA guidance on derivatives is less prescriptive than IRS rules, but assignment in a takeover is still a disposition of the shares and triggers a capital gain or loss in the year it occurs.

Neither the IRS nor the CRA provides a special exemption for involuntary assignment caused by a merger. The tax clock runs from the date of assignment, not the date the deal closes.

How to Reduce This Risk Before It Happens

You cannot predict takeover bids, but you can structure your covered calls to limit the damage when one arrives.

Sell shorter-dated calls. A 14–21 day call gives an acquirer less time to announce a deal while your strike is below the bid price. The premium is lower, but so is your exposure window.

Choose higher strikes. Selling a call 8–10% out-of-the-money instead of 2–3% gives you more room before a bid price exceeds your strike. Yes, you collect less premium, but you retain more upside if a deal materializes.

Avoid selling covered calls before known catalyst dates. Earnings, activist investor deadlines, and sector consolidation waves all raise takeover probability. The SEC requires acquirers to file Schedule TO within 10 business days of commencing a tender offer, but the announcement itself is the event that moves the stock — not the filing.

Size your positions. If a single stock represents a large portion of your portfolio, the covered call caps your gain on a concentrated position. Consider whether the premium income justifies that cap given the stock's acquisition potential.

Finally, watch the options market itself. A sudden spike in call volume or implied volatility on a stock you own — especially in out-of-the-money strikes — can signal that someone in the market knows something. Unusual options activity does not guarantee a bid, but it is a reason to review your position.

What happens to my covered call if the stock gets acquired?

If the acquisition price is above your strike, your call will almost certainly be exercised early and your shares called away at the strike price. You keep the premium you collected, but you miss any gain between your strike and the deal price. The Options Industry Council (OIC) confirms that American-style equity options can be exercised at any time before expiration.

Can I still tender my shares in a takeover if I sold a covered call?

Not while the short call is open — you need the shares to cover the call. To tender your shares, you must first buy back the call at the current market price, which will likely be much higher than what you sold it for. Once the call is closed, you own the shares outright and can participate in the tender offer.

Will I get the full takeover price if I own a covered call?

No. If your strike is below the takeover price, you will receive your strike price plus the premium you originally collected — not the deal price. The difference between your strike and the deal price is the opportunity cost of having sold the call.

What happens to my covered call in a stock-for-stock merger?

The Options Clearing Corporation (OCC) adjusts the contract so the deliverable reflects the new merger consideration instead of the original shares. These adjusted contracts often become illiquid quickly, so monitor OCC adjustment notices through your broker and consider closing the position before the deal closes.

Is the assignment from a takeover a taxable event?

Yes. The IRS treats assignment as a sale of your shares at the strike price, with the premium added to your proceeds. Your holding period and cost basis determine whether the gain is short-term or long-term. Canadian investors should note that the CRA also treats assignment as a disposition of the shares in the year it occurs.

How can I protect myself from losing upside in a takeover when I sell covered calls?

Sell shorter-dated calls and choose strikes that are further out-of-the-money to leave more room between your cap and a potential bid price. Avoid selling calls ahead of known catalyst dates when acquisition risk is elevated. Monitoring unusual spikes in call volume or implied volatility on your holdings can also give you an early warning signal.
