What Is a Tender Offer?
A tender offer is one of the few moments in investing where a company actually asks you a direct question: will you sell, and at what price? Unlike ordinary trading, where you decide when to buy or sell on your own schedule, a tender offer puts a deadline and a specific price in front of you.
The short answer
A tender offer is a formal, public invitation for shareholders to sell their shares back to the company itself or to another party — often an acquiring company — at a stated price and within a specific window of time. It’s typically used when someone wants to buy a large block of shares quickly, sometimes as a step toward acquiring the whole company. Shareholders can choose to sell some, all, or none of their shares, and the outcome depends on how many shares are ultimately tendered.
How you respond through your broker
If you hold shares eligible for a tender offer, your brokerage will usually notify you of the terms and give you a way to respond electronically before the deadline. You generally have a few choices: tender all of your shares, tender only a portion, or take no action and keep your shares as they are. Responding doesn’t happen automatically — it typically requires an active election on your part, which sets a tender offer apart from a mandatory corporate action that applies to every shareholder without any input needed.
Partial versus full acceptance
Some tender offers are for all outstanding shares, while others cap the number the buyer is willing to purchase. In a capped offer, if more shares are tendered than the buyer wants, the purchase can be prorated — meaning each shareholder who tendered has only a portion of their shares actually bought, with the rest returned. This proration detail matters because the price offered might look attractive, but the effective outcome depends on how many other shareholders decide to participate.
What happens if you don’t respond
- You keep your shares. If you take no action, your position generally remains unchanged, and you continue to hold the stock under whatever terms existed before the offer.
- The offer may still succeed without you. If enough other shareholders tender their shares to meet the buyer’s threshold, the deal can proceed, and non-participating shareholders may later see their remaining shares converted through a full merger at potentially different terms.
- You could miss a limited window. Tender offers expire on a stated date, and once that date passes, the specific price offered is no longer available even if you later change your mind.
Reading the terms carefully
Because a tender offer’s price and conditions are set by the party making the offer, it helps to compare that price against the stock’s recent trading range and to note any conditions attached to the offer, such as a minimum number of shares needed for the deal to proceed at all. These details are usually spelled out in the official offer documents your broker makes available, rather than in the news headline describing the deal. It can also help to weigh the offered price against the company’s broader market value rather than judging it on the dollar figure alone, since a premium that looks generous in isolation may look different next to the company’s overall size.
The bottom line
A tender offer puts a concrete choice in front of shareholders with a real deadline attached, which makes it different from the passive experience of holding a stock day to day. Reading the actual terms — the price, the expiration date, any proration rules, and what happens if the offer doesn’t reach its threshold — is what turns a tender offer from a confusing notice into an informed decision about a position you already own.
