Quick Answer
Signing is NOT closing. The definitive agreement binds the parties to close subject to conditions, then a gap period (typically 3 to 9 months) runs the disclosure, regulatory, and communications work. Cash deals file Schedule 14A; stock deals add a joint proxy and prospectus on Form S-4. A buyer can walk only if a closing condition (or a rare Material Adverse Change) fails.
The whole unit on one sheet: the gap window, the disclosure documents, the closing conditions, the Material Adverse Change bar, deal protection, and the communications the exam loves.
The One-Liners That Win Points
- Signing is NOT closing. The definitive agreement creates a binding obligation to close subject to conditions; the deal consummates only when conditions are satisfied (or waived).
- The gap-period workstream applies to BOTH buy-side and sell-side bankers; neither party is finished at signing.
- The banker assists: drafts proxy content, monitors closing conditions, develops communications. The banker does NOT sign the proxy or 8-K, does NOT clear regulators (counsel does), and does NOT distribute press releases (investor relations (IR) does).
- All-cash merger = Schedule 14A proxy only (target vote, no new stock).
- Stock-for-stock merger = joint proxy statement and prospectus on Form S-4: ONE document with TWO regulatory hats (Schedule 14A for the vote, Form S-4 for the new shares).
- The 20% rule (New York Stock Exchange (NYSE) / Nasdaq): an acquirer issuing 20% or more of its outstanding shares triggers an acquirer vote, so the joint proxy schedules TWO meetings.
- Bring-down is SEPARATE from no-MAC. Bring-down asks if signing-date reps are still true at closing; no-MAC asks if the target suffered a Material Adverse Effect (MAE) since signing.
- Material Adverse Change (MAC) protects the BUYER only. The target relies on specific performance to force the buyer to close.
- Break fee is target-pays; reverse termination fee is buyer-pays, and the two are NOT symmetric.
- The Form 8-K announcing the merger agreement is due within 4 BUSINESS days of signing under Item 1.01; the press release and investor deck are FURNISHED (Items 7.01 / 9.01), not filed.

Top Gotchas
- HSR is 30 days for mergers, 15 days for cash tender offers. Trap answers swap the two numbers.
- CFIUS (Committee on Foreign Investment in the United States) is national-security review, not antitrust. It runs in parallel with HSR for foreign acquirers and can block a deal even when antitrust agencies clear it.
- The 10-calendar-day SEC review is just the start; the comment-and-response cycle drives most of the disclosure-side delay.
- MAC requires materiality AND durational significance measured in years, not quarters. A bad quarter does not trigger a walk-away.
- The banker signs a written consent permitting use of the fairness opinion, NOT the proxy itself.
- The press release and investor presentation are FURNISHED, not FILED; that changes liability analysis but NOT the 4-business-day 8-K deadline.
- Bankers monitor; counsel clears. Trap answers suggest the banker files the HSR form.
The Signing-to-Closing Window
- The definitive agreement at signing already contains price, form of consideration (cash, stock, or mix), representations and warranties (R&W), covenants, closing conditions, termination rights, and deal-protection provisions.
- By signing, the sale process has concluded, any fairness opinion is delivered, and both boards have approved.
- Six gap-period workstreams: public announcement, disclosure filings, regulatory clearances, shareholder approval, bring-down, and closing mechanics.
- Mandatory clocks (SEC review, HSR, proxy mailing, share registration/listing) force the 3-to-9-month gap; complex cross-border or heavily regulated deals run longer.
Proxy Statement and Form S-4 Disclosure
- Three document paths: all-cash = Schedule 14A (target only); stock-for-stock = joint proxy and prospectus on Form S-4; acquirer 20% issuance = same joint document with TWO meetings.
- Mixed-consideration deals follow the stock path because stock is still being issued.
- Joint proxy contents: deal terms, background of the merger, board recommendations, fairness-opinion summary, risk factors, pro forma financials, business descriptions, voting and share-exchange mechanics.
- The banker drafts transaction-focused sections (Background of the Merger from the deal log, Opinion of Financial Advisor, Reasons for the Deal, forecasts) but does NOT certify financials (auditors do).
Closing Conditions and Bring-Down Mechanics
- Closing conditions (CPs) are the triggers that must be satisfied (or waived) before either party must close; failure of any unwaived condition gives the affected party a walk-away right.
- Categories: regulatory approvals, shareholder approval, no injunction, bring-down of R&W, no-MAC, covenant compliance, third-party consents, solvency, officers' certificates and legal opinions.
- Bring-down = reps remain accurate at CLOSING, not just signing. General reps use "accurate in all material respects"; fundamental reps (organization, authority, capitalization, brokers' fees) use the tougher "accurate in all respects" (or "in all but de minimis respects").
- Each side delivers a closing certificate signed by an officer attesting reps remain accurate as of closing.
- Regulatory sub-tracks: HSR (filed to the Department of Justice (DOJ) Antitrust Division and Federal Trade Commission (FTC), extendable by a "Second Request"), foreign antitrust (European Union (EU), United Kingdom (UK), others), industry regulators, and CFIUS.
- The banker's primary work product is the closing checklist: every condition with an owner, target date, and status.
Material Adverse Change (MAC) / Material Adverse Effect (MAE) Clauses
- A MAC (also called MAE) clause lets the BUYER walk if the target deteriorates materially between signing and closing; it is the most-negotiated and least-often-invoked provision.
- Structure: a broad trigger definition plus a long list of carve-outs (general economic / industry conditions, changes in law, acts of war / terrorism / pandemics / natural disasters, the deal itself, missed projections), most with a disproportionate-impact override that pulls the target-specific portion back to the seller.
- Akorn v. Fresenius (2018) is the FIRST and (as of 2026) ONLY Delaware Chancery decision to find a true MAE (two independent MAEs: financial collapse plus a regulatory-compliance MAE), affirmed by the Delaware Supreme Court.
- The standard: material AND durationally significant (years, not quarters); the buyer bears the burden of proof.
- Sandbagging is state-specific and contract-driven; Delaware's default is pro-sandbagging (buyer may rely on a known breach if the contract is silent). The target's primary remedy against a walking buyer is specific performance.
Deal Protection: No-Shop, Fiduciary Out, and Termination Fees
- No-shop covenant: the target may NOT solicit, encourage, or initiate alternative proposals, must terminate existing talks, and generally may not share non-public information; it blocks active solicitation, not just acceptance.
- Fiduciary out: the board may RESPOND to an unsolicited bona fide written Superior Proposal, but must give the original buyer notice and a 3-to-5-business-day matching period before terminating.
- Break fee (target-pays): 1% to 4% of equity value; triggers include accepting a Superior Proposal, changing the board recommendation, or a stockholder rejection plus a competing bid.
- Reverse termination fee (buyer-pays): 5% to 10%+ of equity value; triggers include financing failure (most common in private-equity (PE) / leveraged buyout (LBO) deals), regulatory denial, or buyer breach.
- The asymmetry is intentional: the target break fee covers the buyer's sunk costs; the larger buyer fee compensates the target for being left with no deal at all.
External Communications
- Day-of-signing package: joint press release, investor presentation, and joint investor call, all around announcement; employee, customer, and vendor communications follow the public announcement to avoid leaks.
- Form 8-K due within 4 business days of signing: Item 1.01 (Entry into a Material Definitive Agreement), Item 7.01 (Regulation FD), Item 9.01 (exhibits). The agreement attaches as Exhibit 2.1; press release and deck attach as Exhibit 99 series.
- The 8-K is the regulatory floor; press-release and call timing are set by market mechanics and Regulation FD (pushing most announcements to the pre-market window).
- The banker develops and reviews the press release and investor deck, briefs likely investor questions, and rehearses the call with the chief executive officer (CEO) and chief financial officer (CFO), but does NOT issue any of it.
- Regulation FD: pre-announcement, the banker under a non-disclosure agreement (NDA) fits the business-relationship exception; post-announcement, any material follow-up must go through public channels (8-K, press release, public webcast) with no selective tip-offs.
One-Breath Recap
Signing is not closing: the definitive agreement binds the parties to close subject to conditions, and the 3-to-9-month gap period runs disclosure, regulatory clearance, and communications for both buy-side and sell-side bankers. Cash deals file a Schedule 14A proxy while stock deals add a joint proxy and prospectus on Form S-4 (one document, two hats), and the acquirer's 20% share issuance triggers a second vote. Closing conditions must all hold, with bring-down (reps still true at closing) kept distinct from no-MAC (a durationally significant Material Adverse Effect, cleared only once in Delaware, in Akorn v. Fresenius). Deal protection locks the parties in through the no-shop, a fiduciary out with a 3-to-5-business-day matching period, a 1%-to-4% target break fee, and a larger 5%-to-10%+ buyer reverse termination fee. Finally, the merger 8-K is due within 4 business days of signing while the furnished press release and deck ride along as exhibits, and the banker develops all of it but signs and distributes none of it.
