Acquirors of public company targets in negotiated, all-cash acquisitions can now complete a transaction on the 11th business day following the commencement of a tender offer. This can shorten the closing timetable for certain public M&A transactions from a minimum of six weeks to as little as a month.[1] This relief will be particularly relevant for all-cash M&A transactions where the regulatory profile is straightforward and the expiration of the required minimum tender offer period is the principal driver of the closing timetable.
What happened
On April 16, 2026, the Securities and Exchange Commission’s Division of Corporation Finance (Corp Fin) issued an Exemptive Order reducing the minimum offer period for qualifying all-cash, fixed-price equity tender offers from 20 business days to 10 business days, effective immediately.[2]
For qualifying negotiated all-cash acquisitions, halving the minimum offer period combined with the already-reduced 15-calendar-day Hart-Scott-Rodino (HSR) waiting period applicable to cash tender offers can materially compress the end-to-end timeline for completing a two-step transaction and has the potential to shift the calculus for parties weighing a tender offer against a one-step merger.
We expect that many two-step transactions will retain a 20-business-day tender offer period if the expected regulatory clearance timetable – which could be driven either by HSR clearance or non-U.S. merger control or other regulatory approvals – is not sufficiently short to support a compressed timeline.[4] Further, we also expect that the majority of US public M&A transactions will continue to be structured as one-step transactions.
However, the increased timing advantage will be a necessary factor to consider among deal participants and their counsel where speed of execution is an important deal dynamic.
Background
Exchange Act Rule 14e-1(a) requires that tender offers remain open for at least 20 business days. That floor has remained fixed for US public company acquisitions in the four decades since the 1986 amendments to the Exchange Act, even as the financial markets, investor behavior and information infrastructure it was designed to serve were transformed by digital advancements and market practice.
Before the Order, the two-step structure (a tender offer followed by a short-form back-end merger) already offered acquirors the fastest route to closing an all-cash public company transaction. Principally, this is because the offer period and SEC staff review run on parallel tracks rather than in sequence, whereas the SEC has 10 calendar days to decide to review a preliminary merger proxy before a definitive can be filed and disseminated, and because HSR review in an all-cash tender offer has a 15-calendar-day waiting period rather than the standard 30 days in a one-step transaction. Those advantages delivered a timing edge of two to four weeks over a one-step merger on a typical timeline. The Order further widens that timing advantage.
The Order identifies three distinct policy objectives motivating the shortened minimum period:
- Market efficiency. The 20-business-day period creates prolonged windows of deal uncertainty that can distort trading behavior and impose unnecessary costs on offerors and target stockholders alike.
- Technological modernization. Market participants now receive and process disclosure materials far more rapidly than they did when the 20-business-day standard was established. Information technology and digital dissemination have compressed the information gap that a lengthy offer period was designed to address.
- Reduced market exposure. Extended offer periods leave both offerors and stockholders unnecessarily exposed to intervening market volatility, an especially acute concern in volatile rate or macro environments.
Unlike a formal rulemaking, the Order is effective immediately and does not require notice-and-comment procedures. M&A participants may rely on the Order immediately if the following conditions are met.
Conditions for use of the shortened time period
Conditions in order for a third-party tender offer subject to Regulation 14D to utilize the shortened 10-business-day period include:
- Negotiated transaction for all shares of the target company. The offer is made pursuant to a negotiated merger agreement or similar business combination agreement and covers all outstanding shares of the subject class of equity securities.
- All cash, fixed price. Consideration must consist exclusively of cash at a fixed price per share.
- Target board recommendation required promptly. The target company must file and disseminate its Schedule 14D-9 disclosing its recommendation no later than 5:30 pm ET on the first business day following commencement (i.e., when the acquiror files and disseminates its Schedule TO). Practically speaking, the target’s Schedule 14D-9 is commonly filed on the same day as the acquiror’s Schedule TO in a negotiated transaction, so this is already aligned with prevailing market practices.
- Press release with hyperlink at commencement. By 10:00 am ET on the commencement date, the offeror must issue a widely disseminated press release disclosing the basic deal terms together with an active hyperlink to a website where holders may access the complete tender offer materials.
A number of types of transactions are excluded from the shortened period:
- No going-private transactions. The offer must not be subject to Rule 13e-3 under the Exchange Act.
- No cross-border offers. Offers made in reliance on the cross-border exemptions under Rule 14d-1(d) are ineligible.
In a world where hostile bids and competing deal jumps have become ubiquitous, there are a few things to note about the Order if a hostile or competing offer comes into play:
- Hostile offers. Only negotiated, board-supported offers are eligible. The shortened period is unavailable if the target board has not agreed to the transaction.
- No competing offer at launch. At the time the offer is publicly announced, the target must not already be the subject of a previously announced tender offer from another bidder, even if that original offer is hostile. So, a “white knight” transaction that the target negotiated in order to ward off a hostile bid would still be required to be open for at least 20 business days.
- Mandatory extension if a competing offer emerges post-commencement. If a competing tender offer is publicly announced after the initial offer has commenced, the initial offeror must extend its offer so that it remains open for at least 20 business days from the initial commencement date, effectively restoring the standard minimum offer period.
Additionally, as the offer period progresses, the acquiror and target need to keep a close eye on material developments and disclose accordingly:
- Early notice of price changes. Any change in the amount of consideration offered must be publicly announced by 9:00 am ET, no later than the fifth business day before expiration.
- Timely disclosure of other material changes. Any other material changes to the offer’s terms must be publicly announced by 9:00 am ET, no later than the second business day before expiration.
For most negotiated all-cash transactions, these conditions should not present a meaningful barrier to relief. The disclosure and notification requirements either mirror or require only modest adjustments to what deal participants would ordinarily do in a well-run process, and the structural conditions, such as the board recommendation requirement and the full-class offer requirement, are already characteristic of the negotiated transactions.
Looking ahead: A signal of things to come
The Order is a bold and deliberate move by Corp Fin. Rather than allow friction that is plainly visible in modern deal practice to await resolution through a formal rulemaking cycle, Corp Fin reached for its exemptive authority to deliver immediate, actionable relief – accelerating material information delivery to investors and providing a clear framework for structuring change-of-control transactions without adding another item to an already crowded rulemaking agenda.
Corp Fin’s comfort with a press release and a website hyperlink as the primary disclosure mechanism may carry implications beyond the Order’s immediate relief. It is an implicit signal that the information infrastructure supporting tender offer practice has matured, where legacy assumptions regarding how quickly investors gain access to filed issuer information no longer hold. Corp Fin may look to build on the principles underlying the Order, extrapolating its modernizing rationale to revisit aspects of the rules governing timing, disclosure and dissemination in business combination transactions more broadly. Long-standing requirements that predate the digital age, such as the tombstone advertisement requirement, could be ripe for reconsideration as Corp Fin’s modernization efforts in this space continue to take shape.
For market participants, the practical takeaway is straightforward: Corp Fin is engaged, it is moving with purpose, and further guidance in this space may be forthcoming. Dealmakers and their counsel should monitor subsequent Corp Fin pronouncements closely, as the broader framework governing business combination transactions will likely continue to evolve in the near term.

Market participants should carefully consider the fiduciary implications of the shortened timeframe in each specific set of deal circumstances.
