Series 79 M&A, Tender Offers & Restructuring (Function 3 Guide)

Why does Function 3 matter on the Series 79?

Function 3 is the smallest of the Series 79’s three function areas by weight (Function 1 carries 49%, Function 2 carries 27%), but it’s the section most closely tied to what “investment banking” means to most people outside the industry: doing deals. It’s also the most process-heavy section on the exam. Where Function 1 tests whether you can build a DCF and Function 2 tests whether you know the registration exemptions cold, Function 3 tests whether you understand the sequence of a transaction: who does what, in what order, filed on which form, with which rule attached.

That sequencing focus means the material rewards a different kind of studying than Function 1’s modeling work. You’re not solving for an IRR here. You’re tracking a deal through five phases: sell-side or buy-side process, the fairness opinion (if one is needed), the signing-to-closing gap, tender offer mechanics (if the deal is structured that way), and, for distressed situations, financial restructuring inside or outside of bankruptcy court. This article walks through all six FINRA sub-topics in that order: sell-side transactions, buy-side transactions, fairness opinions, signing to closing, tender offer regulation, and financial restructuring and bankruptcy.

How does the sell-side M&A process work?

The sell-side banker represents the company being sold, whether that’s the entire business or a single division. The process starts with a signed engagement letter covering the scope of work, the success fee (often tiered), an exclusivity period, and a tail provision that keeps the banker’s fee alive if a deal closes with a contacted buyer shortly after the engagement ends.

From there, the banker walks the seller through the realistic transaction structures before assuming a straight sale is the answer:

The gotcha the exam likes here: a spinoff goes to every parent shareholder automatically, while a split-off is a choice individual shareholders make. Both can be tax-free under the right conditions; a straight divestiture generally isn’t.

Marketing the deal: teaser, NDA, and CIM

Once the seller commits to a structure, the banker manages a deliberately staged disclosure process so sensitive information only reaches serious, vetted buyers:

Teaser equals no name, no NDA. CIM equals name and projections, after the NDA. A teaser that reveals the seller’s identity defeats the entire point of staged disclosure, and that distinction is exactly the kind of thing the exam tests.

Buyers respond first with non-binding Indications of Interest (IOIs), typically a valuation range rather than a firm number. The seller narrows the field to a handful of finalists, who get access to management presentations, a virtual data room, and often site visits, before submitting a Letter of Intent (LOI): a firm price with committed financing and a defined exclusivity period. The seller picks a winner (or top two) for definitive-agreement negotiations, at which point the deal moves from the banker-led auction to legal-led drafting, with the banker staying on point for the material financial terms.

Along the way, the sell-side banker also coordinates with the seller’s tax and legal advisors on regulatory issues like antitrust review, and with the seller’s leadership on workforce and contract issues (change-of-control triggers in existing debt, employee-benefit obligations, and cultural fit with likely buyers). The banker also evaluates each buyer’s proposal across financial and strategic lenses at once: can the buyer actually pay (cash, remaining debt capacity, ability to issue stock), will the deal help or hurt the buyer’s own earnings per share (a stock deal, at the same valuation, is generally less accretive to the buyer than a cash deal because of the new shares issued), and do the softer social issues matter (headquarters location, brand survival, management’s role after close). Antitrust review under premerger notification rules and, for cross-border deals, national-security review of foreign buyers, round out the regulatory diligence a seller’s banker has to surface before the seller accepts a bid.

How does the buy-side M&A process differ?

Buy-side bankers represent the acquirer, and the process starts from a different question: not “who wants to buy this,” but “can we, and should we.” Before any bid takes shape, the banker confirms the acquirer’s financial capacity (cash on hand, remaining debt headroom, appetite to issue new stock) and strategic rationale (market entry, vertical or horizontal consolidation, technology or talent acquisition, or simply blocking a competitor from getting the asset first). A deal can look great on a valuation model and still be the wrong move if funding it would break a debt covenant or dilute existing shareholders past what the board will accept.

Diagnosing anti-takeover defenses

If the target might resist, the buy-side banker has to diagnose the structural defenses standing in the way before deciding whether to go in friendly or prepare for a fight:

Valuing the target and financing the deal

The buy-side banker applies four standard valuation methods to the target (comparable company analysis, precedent transaction analysis, discounted cash flow analysis, and leveraged buyout analysis), then layers on an accretion/dilution analysis: will the deal increase or decrease the acquirer’s earnings per share once the combined company’s income, new financing costs, and synergies are accounted for? A useful shortcut for an all-stock deal: it tends to be accretive when the acquirer’s price-to-earnings ratio is higher than the target’s, and dilutive when it’s lower, before even factoring in synergies.

Financing runs in parallel with bid development. For a deal larger than cash on hand, the banker arranges a mix from a financing menu that ranges from a bridge loan (short-term, meant to be refinanced quickly) to permanent term debt, high-yield bonds, or new equity issuance, and sellers in competitive auctions typically want to see committed financing, not just a plan, before they’ll take a bid seriously.

Once a preliminary bid is accepted and the deal enters the final round, the buy-side banker runs follow-up due diligence, updates the valuation and financing analysis with what diligence turned up, and (if warranted) hands off to the bank’s fairness committee to prepare the buyer’s own fairness opinion, the same process covered in the next section, just from the other side of the table.

What is a fairness opinion, and who actually needs one?

A fairness opinion is a written conclusion, usually from the deal’s investment bank, that the consideration in an M&A transaction is fair, from a financial point of view, to the party receiving it. That phrasing is precise for a reason: the opinion does not conclude that the price is the best price obtainable, and it doesn’t pass judgment on whether the deal is fair to employees, communities, or anyone outside the specific shareholder class named in the letter. It’s a financial-point-of-view conclusion, full stop, and the board still owns the underlying business decision.

Fairness opinions apply on both buy-side and sell-side deals, and in a stock-for-stock merger it’s common for both sides to get their own, often from different banks. They come up most often in public-company transactions requiring a shareholder vote, going-private transactions, and related-party or conflicted deals like management buyouts, where an independent special committee typically retains its own advisor.

The fairness committee and required disclosures

Before an opinion goes out, the bank issuing it has to run it past an internal fairness committee, a body inside the investment bank (not a committee of the client’s board) built specifically to approve fairness opinions. The committee’s procedures have to address how personnel are selected to serve, what qualifications they need, and critically, a balanced review requirement: people outside the deal team have to take part in the approval, so the same bankers who built the analysis aren’t the only ones blessing it.

When the opinion will reach public shareholders, typically through inclusion in a proxy statement, an additional layer of SEC disclosure requirements attaches, covering the outside advisor’s identity and qualifications, how it was selected, and a summary of the analysis and its conclusions. That disclosure chain connects the fairness opinion directly to the signing-to-closing process covered next, since the proxy statement is exactly where the opinion becomes visible to the shareholders voting on the deal.

What happens between signing and closing?

“Signing to closing” describes the gap between the date the buyer and seller execute the definitive agreement and the date the deal actually closes: consideration paid, securities or assets transferred, target acquired. For large public-company mergers, that gap commonly runs three to nine months, and it applies to both the buy-side and sell-side banker; neither one is finished at signing.

During this window, the banker’s job shifts from deal-making to disclosure, condition monitoring, and communications. That means assisting with the proxy statement or prospectus disclosure sent to shareholders, tracking the status of each closing condition, and helping build the external communications materials (press releases, investor presentations, talking points) that go out once the deal is public.

Closing conditions and the MAC clause

A definitive agreement lists specific conditions that must be satisfied, or waived, before either party is required to close. The most heavily tested one is the Material Adverse Change (MAC) clause, sometimes called a Material Adverse Effect (MAE) clause, which lets the buyer walk away if the target’s business deteriorates materially between signing and closing.

Other standard conditions include regulatory clearance (antitrust review and, where relevant, national-security review for foreign buyers), the required shareholder vote, and a bring-down of the seller’s representations and warranties, meaning those statements made at signing still have to be accurate at closing. Bring-down and MAC are separate tests: bring-down asks whether the seller’s original statements are still true, while MAC asks whether the business itself has suffered a material decline since signing. A buyer can invoke either as grounds to walk.

Deal protection provisions

Definitive agreements also include provisions that lock the parties in while preserving the target board’s obligation to consider a better offer if one shows up:

The fiduciary out is the key release valve: it lets the target’s board respond to an unsolicited proposal that could reasonably be considered superior, but it does not let the board go looking for one. That’s a subtle but frequently tested line: responding to an inbound superior offer is protected; actively shopping the company after signing a no-shop covenant is not.

How does the Williams Act regulate tender offers?

When a deal is structured as a tender offer (the buyer approaches target shareholders directly, rather than negotiating with the target’s board toward a shareholder vote on a merger), a separate and much more detailed rulebook takes over: the Williams Act. The Williams Act amended the Securities Exchange Act of 1934 specifically to regulate tender offers and large beneficial-ownership stakes, and its underlying goal is disclosure and procedural neutrality: giving target shareholders the information and time to decide for themselves, without tilting the playing field toward the bidder or the target.

The bidder’s and target’s disclosure documents

The bidder discloses its offer on Schedule TO, filed at commencement and covering the bidder’s identity, the terms of the offer (price, consideration type, expiration, withdrawal rights), the source of funds, and the bidder’s plans for the target afterward. The target must respond, and the response is mandatory even if the board hasn’t made up its mind yet.

The target must publish its position statement no later than 10 business days after the tender offer is first communicated to shareholders. Staying neutral or saying the board can’t yet decide is allowed; staying silent past that deadline is not.

Timing rules: the minimum offer period and withdrawal rights

The tender offer itself must remain open for at least 20 business days from commencement, the default rule to know for the exam even though a narrow 10-business-day option exists for certain negotiated all-cash deals under a more recent SEC exemptive order. If the bidder changes the price or the percentage of shares it’s seeking during the offer, that change automatically triggers an extension of at least 10 more business days from when the change is announced, so a bidder can’t spring a price change on day 19 and still close on day 20.

Shareholders who tender their shares can withdraw them at any point while the initial offer remains open. That withdrawal right is one of the clearest markers of the Williams Act’s investor-protection design: even after tendering, a shareholder isn’t locked in until the offer actually closes.

Going-private transactions and issuer self-tenders

Two related but distinct frameworks come up when the tender offer involves the company itself rather than a third-party bidder. An issuer self-tender is simply the company buying back its own shares through tender-offer procedures. A going-private transaction is triggered when an issuer or its affiliate engages in a transaction with a reasonable likelihood of taking the company’s shares below the public thresholds for continued reporting, or delisting it from an exchange, and it requires heightened fairness disclosure given the obvious conflict of a company effectively buying out its own public shareholders. An issuer self-tender that happens to cross those going-private thresholds triggers both sets of requirements at once, which is exactly the kind of overlap the exam likes to test.

How does financial restructuring and bankruptcy work?

The final piece of Function 3 covers what happens when a company can’t service its debt: out-of-court restructuring first, and Chapter 11 reorganization if an out-of-court fix isn’t enough. This is the most conceptually different material in Function 3, since it shifts from deal process to creditor priority and court procedure.

The priority waterfall

Every distressed-company question starts from the same idea: claimants get paid in a strict order, and each rank has to be paid in full before the next one sees anything.

Chapter 11 reorganization: the players and the process

Filing a Chapter 11 petition triggers an automatic stay, which immediately halts collection efforts, foreclosures, and lawsuits against the debtor, giving the company breathing room to reorganize. The debtor typically remains in control as a debtor in possession, continuing to run the business under court oversight; a separate Chapter 11 trustee is appointed only in unusual cases involving fraud or gross mismanagement, not as the default. An Official Committee of Unsecured Creditors represents that class, hiring its own advisors at the estate’s expense, and the U.S. Trustee (a Department of Justice office) oversees the administration of the case without stepping in to run the company.

Companies in Chapter 11 often need new financing to keep operating, which is where DIP financing comes in. The Bankruptcy Code authorizes it in tiers, from ordinary unsecured credit needing no special approval up to credit secured by a priming lien senior to existing secured lenders, which requires the court to find the primed lender is adequately protected. DIP financing typically carries the highest priority claim in the entire case, which is why it sits at the top of the waterfall above.

The company eventually files a plan of reorganization, paired with a disclosure statement the court has to approve as containing adequate information before creditors vote. Each class of claims votes separately, and a class accepts the plan if more than two-thirds of the claim amount and more than half the number of claims actually voting say yes. Classes left unimpaired (their rights unchanged) are deemed to accept automatically and don’t vote at all.

Speed matters: three flavors of Chapter 11, plus Section 363 sales

Not every Chapter 11 case takes the same amount of time. The difference comes down to how much creditor consensus exists before the company ever files:

A Section 363 sale offers a faster, separate path for selling assets during a bankruptcy case, letting a debtor sell property free and clear of liens and other claims with court approval, without going through the full plan confirmation process. It’s commonly used for distressed M&A where speed matters more than the more deliberate plan process, often run through a stalking-horse bidder and an auction.

Out-of-court alternatives

Before reaching for Chapter 11 at all, companies often try an out-of-court exchange offer: swapping existing bondholders’ old bonds for new securities with different terms. These exchanges are frequently structured with a consent solicitation attached, amending the old bonds’ covenants for anyone who doesn’t tender, which creates real pressure to participate. Out-of-court exchanges can typically proceed without full securities registration when they’re conducted exclusively with existing holders of the same issuer and no solicitation commission is paid, while securities issued under a confirmed Chapter 11 plan get their own separate registration exemption. Both paths exist because forcing every restructuring through full SEC registration would make an already difficult situation slower and more expensive.

How does the exam test Function 3?

Function 3 questions are mostly scenario-based: a fact pattern describing a deal at a specific stage, asking which document applies, which party is responsible for it, or which timing rule governs. The wrong answers are frequently plausible-sounding rules borrowed from an adjacent but different framework, like applying a merger-vote timeline to a tender offer, or mixing up which schedule the bidder files versus which one the target files.

Because this section spans deal process, securities regulation, and bankruptcy law in roughly equal measure, the most efficient prep approach is to drill each of the six sub-areas separately before mixing them together in full-length practice: sell-side process, buy-side process, fairness opinions, signing to closing, tender offer regulation, and financial restructuring. Once you can identify which of the six a given question belongs to before reading the answer choices, the choices themselves get much easier to eliminate.

This section connects directly to the rest of the exam. Function 1’s valuation methods (comparable companies, precedent transactions, DCF, LBO) are the same four methods applied here on both the buy-side and sell-side, just seen from the deal-process angle instead of the modeling angle. And Function 2’s registration mechanics, covered separately, are what actually govern the S-4 and proxy filings this article’s signing-to-closing section only describes at the process level. Reviewing collection, analysis and evaluation of data and underwriting and new financing transactions alongside this article will reinforce those connections rather than treating all three functions as separate silos.

When you’re ready to test yourself, the Series 79 practice test mixes Function 3 scenarios in with Functions 1 and 2 the same way the real exam does.
