A tender offer is the faster route on paper: federal rules let it close after just 20 business days, while a merger vote must first clear a proxy filing, a record date and a shareholder meeting. But fast on paper is not the same as cash in your account. In 2026, two tender offers covered on What's On Finance ended with tendered shares handed back unpaid. Meanwhile, a plain-vanilla merger vote went from signing to closing in 161 days.
Route 1: The Tender Offer
In a tender offer, the buyer bids for shares directly. It files a Schedule TO with the SEC, including an Offer to Purchase. The target's board answers with a Schedule 14D-9, which says whether it recommends tendering, rejecting or staying neutral.
The clock is set by federal rule. Under Rule 14e-1(a), an offer must stay open at least 20 business days from the date it is first published or sent to holders. Under Rule 14e-1(b), any change in the price or in the percentage of shares sought means the offer must stay open at least 10 business days from the date that change is announced.
Four more mechanics matter:
- Withdrawal rights. Under Rule 14d-7, tendered shares can be pulled back while the offer remains open. Tendering is reversible until the expiration time.
- The minimum tender condition. The buyer won't accept any shares unless enough are tendered; in both 2026 examples below, that meant a majority. If the count falls short, nobody gets paid.
- Other conditions. Antitrust clearance (HSR timing has its own explainer), no injunctions, and whatever else the deal documents list.
- The back-end merger. For a Delaware target, Section 251(h) of the Delaware General Corporation Law allows the follow-on merger with no stockholder vote. This applies once the buyer holds whatever percentage would otherwise have been needed to approve the deal. Each untendered share is converted into "the same amount and kind" of consideration paid in the offer.
Route 2: The One-Step Merger Vote
The slower route runs through a proxy statement. The target files a preliminary proxy (PREM14A). Rule 14a-6(a) requires it to be on file at least 10 calendar days before the definitive version goes out, and SEC staff may review it in that window. Then comes the definitive proxy (DEFM14A), mailed to holders as of a record date, followed by a special meeting.
The threshold comes from state law and the company's charter. At Talkspace, for example, it was a majority of the outstanding shares, not a majority of the votes cast. That detail matters: a share that never votes counts the same as a "no."
Side by Side: Tender Offer vs Merger Vote
| Item | Tender offer (with 251(h) merger) | One-step merger vote |
|---|---|---|
| Key filings | Schedule TO, Schedule 14D-9, amendments for each extension | PREM14A, DEFM14A, 8-K with vote results |
| Minimum legal period | 20 business days open; +10 business days after a price or percentage change | Preliminary proxy on file at least 10 calendar days before the definitive proxy |
| What the holder does | Tenders through a broker before expiration, or does nothing | Votes by proxy or at the meeting, if holding on the record date |
| Non-participants | Converted in the back-end merger into the same consideration, if the offer closes | Converted at closing like everyone else, if the vote passes |
| Failure mode | Minimum condition missed or other condition unmet; tendered shares returned | Vote fails, or regulatory or financing conditions stall the closing |
Worked Example: Lisata, 64.67% Tendered and Zero Paid
Lisata Therapeutics ($LSTA) signed a merger agreement with Kuva Labs on March 6, 2026. The offer was $4.00 per share in cash plus one contingent value right worth up to $3.00. (Our earlier breakdown covers the CVR.) Lisata's board recommended tendering. The deal was structured for a back-end merger under Section 251(h), with a minimum tender condition of a majority of outstanding shares, counting Kuva's rollover shares.
| Date (2026) | Event, per SEC filings |
|---|---|
| March 6 | Merger agreement signed |
| June 10 | Schedule TO filed; offer set to expire July 10 |
| July 10 | About 5,105,552 shares tendered, 55.98% of 9,119,742 outstanding; offer extended to July 16 |
| July 16 | About 5,897,848 shares tendered as of July 15, 64.67%; offer extended to July 20 |
| July 23 | Offer terminated; no shares accepted, tendered shares returned |
The arithmetic: 96 days passed from signing (March 6) to launch (June 10). Holders who tendered at launch then had their shares tied up for 43 days, from June 10 to July 23. The tendered count alone was already above the majority minimum. According to the final Schedule TO amendment, the offer died because of "the inability of the Purchaser to obtain the financing necessary to satisfy the conditions of the Offer." The warning was in the June 10 Offer to Purchase: no financing condition, but no committed financing either, after Kuva's original commitment letters fell through. Lisata sued Kuva in the Delaware Court of Chancery on July 31, 2026, alleging breach of the merger agreement, per an 8-K.
Worked Example: Genco, a Hostile Offer That Ran Out the Clock
On May 4, 2026, Diana Shipping ($DSX) launched an unsolicited tender offer for Genco Shipping & Trading ($GNK) at $23.50 per share in cash, set to expire June 2. Genco's board answered in a May 15 Schedule 14D-9, unanimously recommending that holders "REJECT the Offer and NOT TENDER." On May 27, Diana raised the price to $24.80 and pushed the deadline to June 26. The old June 2 date sat only four business days later, short of the 10 that Rule 14e-1(b) requires after a price change. As of May 27, just 38 shares had been tendered. (Background: Genco declines Diana's tender offer and what the raised offer means.)
| Count date (2026) | Shares tendered | % of all Genco shares | New expiration |
|---|---|---|---|
| June 26 | 10,583,484 | 24.3% | July 10 |
| July 10 | 11,081,926 | 25.4% | July 24 |
| July 24 (final) | 11,778,419 | 27% | Expired |
Genco's minimum tender condition required a majority of shares on a fully diluted basis, counting the shares Diana already owned. The offer expired on July 24 with its conditions unmet, and Diana told the depositary to return every tendered share. From launch to expiry was 81 days. A separate June 17 proposal to Genco's board, valued by Diana at $27.34 per share in cash and stock, never changed the $24.80 tender price.
Worked Example: Talkspace, the Proxy Route
Talkspace ($TALK) agreed on March 9, 2026 to be acquired by Universal Health Services ($UHS) for $5.25 per share in cash through a one-step merger vote.
| Date (2026) | Step | Days since signing |
|---|---|---|
| March 9 | Merger agreement announced (8-K) | 0 |
| April 7 | Preliminary proxy (PREM14A) | 29 |
| April 13 | Record date | 35 |
| April 20 | Definitive proxy (DEFM14A) | 42 |
| May 29 | Special meeting; about 73.48% of outstanding shares vote for | 81 |
| August 17 | Merger closes | 161 |
The arithmetic: March 9 to May 29 is 81 days, which matches Genco's launch-to-expiry span to the day. The record date came a week before the definitive proxy was filed, so anyone who bought after April 13 got no vote. Another 80 days passed between the vote and the close (May 29 to August 17). An August 12 8-K reported that the state healthcare-law waiting periods the deal was conditioned on had cleared as of August 11.
There is also a third route. Bumble ($BMBL) said in its October 13, 2026 8-K that principal stockholders had already delivered a written consent adopting the merger agreement. Bumble said it will file an information statement under Schedule 14C, so there is no ballot (see our Bumble take-private explainer).
The Common Mistake: "Tender Now or Get Left Behind"
Mistake one: tendering means faster cash. Nobody is paid until the buyer accepts shares, and the buyer accepts nothing until every condition is met. Lisata holders who tendered on day one waited 43 days and got their shares back. Meanwhile, untendered holders could sell at any time; tendered shares can't be sold until withdrawn.
Mistake two: not tendering means losing out. In a negotiated deal under Section 251(h), untendered shares are converted into the same consideration in the back-end merger. Not tendering typically means getting paid a little later, not getting nothing. A hostile bid with no merger agreement, like Diana's, makes no such promise. Appraisal rights under Delaware §262 can apply to non-tendering holders. That is a legal question, and nothing here is legal or tax advice.
A Holder's Checklist
- Identify the route: Schedule TO (tender), DEFM14A (vote), or an information statement (written consent).
- Note the expiration time or the record date, and ask your broker for its own deadline, which can come before the legal one.
- Read the minimum condition and compare it with the latest tendered-share count in each Schedule TO amendment.
- Read the "Source and Amount of Funds" section. "No financing condition" and "no committed financing" can sit side by side, as they did at Lisata.
- Read the board's 14D-9 or proxy recommendation.
- In a vote that needs a majority of outstanding shares, remember that not voting counts as voting no.
- Check for a 251(h) back-end merger before assuming untendered shares will be cashed out.

Bull/Bear Verdict
Bull Case: Where this approach helps: knowing the route tells a holder which filings to watch. When a funded, board-backed tender offer clears its conditions, it can close well inside the 81 days Talkspace needed just to reach its vote.
Bear Case: Where it misleads: "20 business days" is a legal floor, not a forecast. Lisata and Genco both ran far past it and paid nothing. Talkspace's vote came 80 days before its closing. The route sets the minimum; conditions set the real date.
FAQ
Is a tender offer always faster than a merger vote?
Only on paper. Extensions, financing and regulatory conditions can stretch either route for months.
Can I change my mind after tendering?
Yes. Under Rule 14d-7, tendered shares can be withdrawn while the offer is open. In Lisata's offer, tenders became irrevocable after the expiration time, with a further withdrawal right if shares had not been accepted by August 9, 2026.
What happens if I don't tender and the offer succeeds?
In a Delaware deal set up under Section 251(h), untendered shares are converted into the same consideration in the back-end merger, which the statute says must happen "as soon as practicable" after the offer closes. Hostile offers without a merger agreement come with no such guarantee.
Why does the record date matter in a merger vote?
Only holders as of the record date can vote. At Talkspace, the April 13, 2026 record date came before the definitive proxy was filed on April 20.
