Managing a Merger Investigation: A Practical Guide

Document type: Guide Practice area: Corporate — Antitrust Jurisdiction: United States (federal) Last reviewed: 5 September 2026

Who this is for

Deal counsel and the in-house lawyer running a transaction that has, or may have, an antitrust problem.

Our example is Brackenridge Materials, which agreed to acquire Corvallis Specialty Coatings. The two are the leading suppliers of a specialty industrial coating in North America, with a combined share around 55% in one product tier and much less elsewhere. Brackenridge's general counsel is Anwar Delacroix-Sonnenfeld.

The organizing principle: by the time a second request issues, most of what determines the outcome has already happened — in the overlap analysis nobody ran, the documents executives wrote two years ago, and the risk allocation negotiated at signing. Do that work first.

Step 1 — Map the overlaps before anyone signs

Work at the product and geography level, not the corporate level. Section 7 of the Clayton Act, 15 U.S.C. § 18 reaches harm in any line of commerce in any section of the country. A national transaction is challenged on a single niche or a single metropolitan area.

Build the matrix from the parties' own revenue data: every product line, every geography, both parties' revenue, estimated shares, and the identity of the other significant competitors in each cell.

Then answer the question that actually matters: for each overlap, who does each party lose deals to, and in what order? Win-loss records, bid data, and sales force reporting answer this better than published market shares, and the unilateral effects analysis turns on it.

Screen the non-horizontal theories too. Does either party supply the other's competitors? Would the combination give access to rivals' competitively sensitive information? Is the target a recent entrant or a nascent competitor? Is this the latest in a series of acquisitions that would be assessed cumulatively?

Brackenridge's matrix showed a real problem in one tier and nothing anywhere else — which is the usual pattern and the reason the analysis must be granular.

Step 2 — Run the document assessment before signing

This is the highest-value step in the guide and it costs comparatively little.

Search the likely custodians for the predictable themes: the target described as the principal competitive constraint; pricing effects in the deal model; statements about consolidation, discipline, or the ability to raise price; competitor lists that are shorter than the parties' lawyers would like.

Understand that these documents get produced with the initial filing. 16 C.F.R. Part 803 requires production of specified categories of documents analyzing the transaction with the notification — before any second request issues.

When you find bad documents — and you will — do three things. Understand what the author actually meant and what role they played. Locate the context: the data behind a modeling placeholder, the specific product tier a "principal obstacle" comment referred to, the correction someone sent afterward. And build the explanation before filing rather than after production.

Do not clean the file. Deleting or altering documents once a transaction is contemplated is obstruction, it is discovered, and it converts a civil review into something far worse. Preserve early, broadly, and verifiably.

And do not write a memorandum explaining that the bad email did not mean what it says. That memorandum is produced too.

Step 3 — Price the risk in the agreement

The Step 1 and Step 2 findings should set these terms, not precedent.

The efforts covenant, on a spectrum from commercially reasonable efforts through reasonable best efforts to a hell or high water obligation requiring the buyer to divest and litigate as necessary. Between them: an obligation capped by reference to assets generating up to a stated revenue amount, or an obligation to litigate but not to divest beyond a threshold.

The outside date, with defined automatic extensions tied to regulatory review and a limit on the number.

The reverse termination fee payable if the deal fails on antitrust grounds. Sizing it is where the risk is actually allocated.

Interim operating covenants, drafted to preserve the business without creating buyer control — see Step 8.

Process control: who leads the regulatory effort, who attends agency meetings, who approves submissions, and the seller's information and consultation rights.

Cooperation obligations, including the seller's obligation to produce data and make witnesses available. This is a substantial burden and should be specified rather than assumed.

And the closing condition itself: expiration of the waiting period, and whether the absence of a pending challenge is a condition. A buyer obliged to close over an agency lawsuit is in a very different position.

Step 4 — File, and manage the initial waiting period

Run reportability in writing under 15 U.S.C. § 18a and 16 C.F.R. Part 801, and re-run it if the structure changes — a restructured deal can become reportable when the original was not.

Prepare the Part 803 document production carefully, with the Step 2 context ready.

Expect clearance between the agencies in the first days. Which agency takes the review matters: procedures, remedy practice, and litigation posture differ between the Federal Trade Commission and the Antitrust Division.

Engage early. A voluntary meeting with staff during the initial period, presenting the business and the market, is frequently worth more than anything filed. Bring a short deck and the data.

Expect a pull-and-refile request. A party may withdraw and refile once, restarting the 30-day period without a new fee. The agency asks when it is not ready to decide, and the alternative it is contemplating is a second request. Agree.

And use those extra 30 days. They are not a pause; they are the last chance to persuade before a second request converts the transaction into a litigation project.

Step 5 — Negotiate the second request, in the first three weeks

The cost and duration of the entire response are set here.

Custodian count is the dominant driver. A demand listing 40 custodians is an opening position. Reduce it with a documented explanation of each person's actual role — who set pricing, who decided on products, who dealt with the overlap customers — and expect to land materially lower. Brackenridge went from 38 to 16.

Then date range, category by category. Five years for strategic documents may be reasonable; five years of routine transactional email is not.

Then the data specifications. Structured productions — transaction-level pricing, bid records, customer data — frequently require the finance and IT teams more than the lawyers, and those specifications are negotiable in format, granularity, and period.

Agree the protocol in writing before review begins: search terms or a technology-assisted review methodology with validation, de-duplication and threading, family production rules, privilege log format, rolling production schedule, and the treatment of foreign-language and legacy data.

Staff it as litigation. Review team, project manager, e-discovery vendor, and company personnel who can explain the data. The business people have day jobs; get their time committed in writing.

Do not underestimate the narrative specifications. The requests asking the company to describe its markets, competitors, pricing, and plans are answered by counsel with the business and become admissions. Draft them like pleadings.

Budget honestly and early. For a substantial transaction, second request compliance commonly runs into the millions, and the number the board hears in month two should be the number it sees in month eight.

Step 6 — Run the substantive campaign in parallel

Parties that complete compliance and only then begin persuading have wasted the months when staff views were forming.

The economic submission. Diversion ratios and margins for unilateral effects; entry and expansion evidence; efficiencies that are merger-specific, verifiable, and passed through. Retain the economist early; the analysis takes months and requires the same data the second request demands.

Customer outreach, done carefully. The agency will interview customers, and customer testimony is frequently decisive. The parties should understand what customers will say — which means talking to them — while scrupulously avoiding anything that could be characterized as coaching or pressure. Document the process.

The market story. Who competes, on what, and why the overlap is narrower or the constraints broader than the shares suggest. Ground it in win-loss data, bid records, and customer behavior rather than assertion.

Rebuttal evidence in the United States v. General Dynamics Corp., 415 U.S. 486 (1974) mold, where available: reasons the historical share statistics misdescribe future competitive significance — committed capacity, expiring contracts, technological change, a declining product.

Meet the staff repeatedly. Line attorneys and economists form views during compliance. A party that has walked them through the business, the data, and the market is in a different position at certification than one that arrives with a brief.

And identify the theory early. Ask the staff what concerns them. They frequently say, and the answer determines whether the campaign is about market definition, diversion, or a vertical foreclosure theory nobody screened for.

Step 7 — Certify, and decide about a timing agreement

Substantial compliance is the parties' own certification, and it restarts a 30-day clock (10 days for cash tender offers) under § 18a(e).

Certify at the right moment. Too early and the agency may dispute compliance, which stops the clock and damages credibility. Too late and the deal slips. Confirm the position with staff before filing.

Then the timing agreement. The agency will ask the parties not to close for a period after certification — commonly 60 to 90 days rather than the statutory 30 — with advance notice before closing, in exchange for a schedule of engagement and a decision.

Agree, and negotiate the terms: the length of the post-certification period; the number and timing of substantive meetings; access to the front office and the decision-makers, not only line staff; commitments about the economic and data submissions; and the notice period before closing.

Why agree. An agency that has not finished when the clock expires sues to preserve the status quo. The timing agreement converts a litigation deadline into a negotiation schedule.

And tell the board what it means: the deal is now on a schedule measured in months, and the outside date in the merger agreement needs to accommodate it.

Step 8 — Keep the companies apart

Until the waiting period ends, the parties remain independent competitors, and coordination is unlawful under § 18a and potentially Sherman Act § 1.

Write the clean team protocol before any information moves. A defined group — outside advisors plus a small number of employees who are not commercially responsible for the affected products — receives sensitive information, performs integration analysis, and does not report the underlying data back into the business. Membership, scope, and outputs documented.

What does not move between the parties: current pricing, customer-specific terms, bid information, forward commercial plans, and cost data at a granularity that reveals pricing.

What the buyer does not do: approve or direct the target's pricing, bids, or customer terms; attend customer meetings as one company; allocate customers or territories "for after closing"; integrate sales forces; or transfer employees.

Review the interim operating covenants with antitrust counsel. A consent right over ordinary-course pricing is a control right whatever the merger agreement calls it.

Train the business teams. The enforcement problem is enthusiasm, not comprehension — people excited about a deal begin acting like one company because it is efficient. Give the deal team a single point of contact who can answer "can we do this" within an hour.

And understand the exposure: per-day civil penalties, an independent Sherman Act claim, and — practically — evidence handed to the reviewing agency that the parties already regard themselves as one firm.

Step 9 — Design a remedy that will actually be accepted

Bring it early. A viable proposal presented before the agency commits to a challenge is a negotiation; the same proposal offered as an alternative to litigation is usually declined, and offering it signals that the parties know the deal has a problem.

Structural relief is strongly preferred. Divestiture restores an independent competitor without ongoing supervision.

Design the package as a business, not as a concession. Manufacturing, intellectual property, personnel, customer relationships, supply arrangements, and whatever else the divested line needs to stand alone. A package assembled to minimize what the parties give up fails, and the failure is remembered.

Find an upfront buyer. Financially capable, experienced, independent, and with the incentive and ability to compete. The agencies frequently require the purchaser to be identified and approved before closing, and an approved upfront buyer is often the difference between acceptance and rejection.

Expect to negotiate transitional support — supply agreements, transition services, technology licenses — and expect the agency to dislike the entanglement while recognizing its necessity. Keep the terms short and the exits clean.

Anticipate a crown jewel provision requiring a larger divestiture if the first is not completed.

Behavioral remedies are a hard sell, especially for horizontal overlaps: firewalls, non-discrimination commitments, and supply obligations ask the agency to regulate rather than restore competition, and their enforcement record is mixed. They appear mainly in vertical matters and their acceptance varies with enforcement policy.

Then the decree machinery. Department of Justice settlements are entered as consent judgments subject to public comment and judicial review; Federal Trade Commission settlements proceed by consent order with a comment period. Both carry monitoring, reporting, and compliance obligations that outlast the deal team — assign an owner.

Step 10 — If there is no remedy

Understand the posture. The Antitrust Division sues in district court under 15 U.S.C. § 25. The Federal Trade Commission typically seeks a preliminary injunction under 15 U.S.C. § 53(b) while an administrative proceeding runs in parallel.

Recognize that the preliminary injunction stage is effectively final. Financing, employees, and customers do not survive the delay, whatever the administrative case would later hold.

Prepare for a fast, expert-heavy trial — months, not years. Ordinary-course documents, executive testimony, customer testimony, and competing economic models. A purchaser who credibly testifies that the merging parties are its only two real options outweighs a great deal of econometrics.

Know the burden framework. The government establishes a prima facie case, commonly through market definition and concentration; the burden shifts to defendants to rebut; the ultimate burden of persuasion remains with the government. General Dynamics is the template for rebuttal.

Consider litigating the fix — the transaction as modified by a proposed divestiture the agency rejected — recognizing that whether the court evaluates the deal with or without the remedy is contested and consequential.

And make it a business decision. Litigation costs many millions, takes a year or more, and leaves the target in limbo. Whether to fight is decided by the parties' relative tolerance for that, which is precisely what the efforts covenant and reverse termination fee in Step 3 were meant to allocate.

Step 11 — Do not forget the other reviewers

Build one regulatory calendar at signing, showing every filing, its trigger, timeline, whether it is suspensory, and its owner.

State attorneys general have independent authority and have become materially more active. They frequently participate in the federal investigation and sometimes sue independently. Brief them deliberately.

Foreign merger control in every jurisdiction with a filing trigger. A single suspensory regime sets the closing date regardless of where the commercial center of gravity lies. Keep submissions consistent across jurisdictions; they are compared.

Foreign investment review, where the buyer has foreign ownership or the target holds critical technology, sensitive data, or covered real estate — a separate process with its own timeline and its own ability to block.

Sector regulators in communications, energy, banking, insurance, transportation, healthcare, and defense, several of which apply a broader public interest standard than competition alone.

And check the outside date against all of it, because deals fail when the merger agreement's clock was set by reference to the antitrust review while another suspensory clearance was still running.

Step 4A — Briefing the board, and re-briefing it

A merger review is a year-long project with a binary outcome, and boards experience it badly unless they are managed as deliberately as the agency is.

At signing, tell them three things. The overlap analysis and where the problem is. The realistic timeline — a contested review runs a year or more from signing, not the thirty days the statute describes. And the risk allocation actually negotiated: what the efforts covenant requires the buyer to do, what the divestiture cap is, and what the reverse termination fee compensates.

Then set a reporting cadence — monthly is usually right — with a one-page format: where we are, what the agency has asked, what we have submitted, what the next milestone is, and what has changed in the assessment.

Give them the decision points in advance. There are usually three: whether to agree a pull-and-refile; whether to propose a remedy and what package; and whether to litigate. Each is a business decision with a number attached, and a board that has seen them coming decides better than one presented with a recommendation and a deadline.

Be honest when the assessment worsens. The most damaging thing counsel can do is maintain an optimistic view through month eight and then arrive with a divestiture recommendation. Update the probability honestly, in writing, as the agency's theory becomes clear.

Prepare them for the cost curve. Second request compliance dominates and lands in a concentrated period. The number presented in month two should be the number seen in month eight, with the drivers named.

And address disclosure and reserves early for a public company: whether the matter is probable and estimable, what must be said about the review's status, and what the effect of a prolonged review is on the stock. Involve the auditors and disclosure counsel before the question is urgent.

Step 5A — Executing the divestiture

Agreeing a remedy is not completing one, and the divestiture process is a second transaction run under a deadline set by a consent decree.

Carve out a business, not a set of assets. The package needs the manufacturing capability, the intellectual property and know-how, the regulatory registrations, the customer contracts and relationships, the supply arrangements, and — critically — the people. Divestitures fail when the technical staff who actually make the product stay behind.

Assign a dedicated team. The people running the main integration cannot also run the divestiture; their incentives point the wrong way, and the agency notices.

Preserve the divested business in the meantime. Consent decrees include hold-separate obligations requiring the business to be maintained as a viable competitor pending sale — with independent management, continued investment, and no poaching of its customers or staff. Breaching a hold-separate order is a fast route to a much larger problem.

Manage the buyer approval process. The agency approves the purchaser and the terms. Expect diligence on the buyer's financing, its experience, and its independence, and expect the agency to test whether the buyer will genuinely compete rather than harvest.

Negotiate the transitional arrangements tightly. Supply agreements, transition services, and technology licenses are necessary and are entanglements the agency dislikes. Keep terms short, pricing arm's-length, and exits clean — and remember these become long-term commercial relationships with a company you just created as a competitor.

Watch the crown jewel trigger. Where the decree provides for a larger divestiture if the first is not completed by a date, that date is real and it is not extended sympathetically.

And staff the compliance obligations after closing. Monitoring, reporting, certifications, and — in many decrees — a monitor or divestiture trustee. Assign an owner with authority and a calendar. A failed divestiture is worse than no remedy: it brings the agency back, and it is remembered on the company's next transaction.

Step 6A — Preparing witnesses and the business team

At several points the agency will talk to people who do not practice law, and those conversations shape the outcome more than any brief.

Investigational hearings and depositions. In a second request the agency may take sworn testimony. The witnesses are executives describing their own markets, and they are not accustomed to being cross-examined about a document they wrote three years ago and do not remember.

Prepare with documents, not with themes. A witness who has read their own emails, understands what was happening at the time, and can explain it accurately is credible. One who has been told the company's position and not shown the documents will be impeached with them.

Teach three habits. Answer the question asked. Say "I don't recall" when true, and mean it. And do not speculate about what a document meant if you did not write it or do not remember — speculation becomes an admission.

Do not script. Coached answers are obvious, and the appearance of coaching taints everything else the party has said.

Prepare the sales and commercial teams separately. They will be asked how deals are won, who they compete against, and what happens when a customer threatens to switch. Their honest answers are frequently the party's best evidence — and their casual overstatement ("we own that segment") is frequently the government's.

Brief everyone on the customer contact rule. Customers will be interviewed. Employees must not discuss the investigation with them, must not suggest what to say, and must report any customer who mentions being contacted. Write this down; a well-meaning sales representative reassuring a customer about "what to tell the government" creates a problem no brief will fix.

And prepare the executives who will meet the staff. The most effective advocacy in a merger review is a commercial leader explaining the market with the data in front of her. That takes rehearsal — of the substance, not of a script.

Step 7A — Assembling the team and the budget

A contested merger review is a large project, and staffing it correctly at the start is cheaper than staffing it correctly in month six.

Antitrust counsel who does this. Merger review is a specialist practice with its own relationships, its own conventions, and its own sense of what staff will accept. A generalist corporate group running a second request will spend more and achieve less.

An economist, retained early. Not after the second request issues — the analysis requires the same data, takes months, and shapes what the parties tell the staff in the first meetings.

Document review capacity. A managed review team and an e-discovery vendor, contracted before the second request lands, so that mobilization is not itself a three-week delay.

Company personnel, committed in writing. The finance and IT people who can produce and explain the transaction data; the commercial people who can explain how deals are actually won; a project manager who is not a lawyer. Their time is the resource most likely to be assumed and least likely to be available.

Local and foreign counsel for every other filing on the regulatory calendar.

Then the budget, in phases: filing and initial period; second request compliance, which dominates; economic work; the substantive campaign; remedy negotiation and the divestiture process; and, if it comes, litigation. Present it as a range with the drivers named — custodian count, date range, whether there is a remedy, whether there is litigation — so that the board understands what moves the number.

And name a single point of accountability. Merger reviews are run by a committee of deal counsel, antitrust counsel, the business, and the client's own lawyers, and the ones that go badly are the ones where nobody could say who was deciding.

Step 8A — The economics, in terms a deal team can use

The economic case is built by economists and decided by lawyers and judges, so the deal team needs to understand what it is buying.

Diversion ratios are the center of a unilateral effects case. If Brackenridge raises price and loses 100 units, how many go to Corvallis rather than to a third supplier? A high diversion ratio between the merging parties means the merged firm recaptures its own lost sales, which makes a price increase profitable. This is estimated from win-loss data, bid records, switching evidence, and — where available — a customer survey.

Margins matter as much as shares. The profitability of a price increase depends on the margin on the recaptured sales. High-margin, high-diversion combinations produce large predicted effects even at modest shares.

Upward pricing pressure and merger simulation convert those inputs into a predicted price effect. They are useful and they are contestable: the results are sensitive to assumptions about diversion, margins, and repositioning, and a defense economist will press exactly there.

What actually rebuts. Evidence that customers have real, used alternatives — multi-sourcing, qualification of new suppliers, competitive bidding with three or more participants. Evidence of repositioning: that other suppliers can and do move into the segment. Entry that is timely, likely, and sufficient. And General Dynamics-style evidence that historical shares misstate future competitive significance.

Efficiencies, honestly assessed. They must be merger-specific, verifiable, and passed through. Synergy models prepared for the board are the starting point and are usually inadequate — they include cost savings achievable without the merger and revenue synergies that are not cognizable. Have the economist test them before they are submitted, because a rejected efficiencies claim damages credibility on everything else.

Get the data early. The economist needs transaction-level pricing, bid records, and customer data — the same data the second request demands. Running both from a single extraction saves months.

And translate for the decision-makers. A board approving a divestiture needs to understand, in a paragraph, why the agency thinks price would rise. If counsel cannot explain the theory that simply, the defense of it will not be simple either.

Step 9A — Running the deal while the review runs

A year of regulatory review happens to a business, and managing that is as much of the job as managing the agency.

The employees. The target's people know the deal may fail and that their jobs may change either way. Attrition during a long review is the most common way value leaks out of a transaction, and it falls hardest on exactly the people the buyer wanted. Retention arrangements, honest communication about timing, and — critically — clarity that the buyer cannot make commitments about roles before closing.

The customers. Competitors will tell the target's customers the deal is in trouble and that they should switch. Customers will also be interviewed by the agency. The target must continue selling normally, and the parties must not present jointly — which means the commercial teams need a script and a boundary, not a general instruction to be careful.

The business plan. The target continues to operate, invest, and make decisions under interim covenants. Covenants drafted to protect the buyer can paralyze the seller: a consent right over ordinary capital expenditure or hiring becomes a real operating constraint over twelve months. Draft with the duration in mind and build in materiality thresholds.

The financing. Debt commitments have outside dates and market flex. A review that runs longer than the commitment forces a refinancing on whatever terms exist then, and the risk of that sits with the buyer.

The seller's alternatives. A seller locked up for a year under exclusivity, in a deal that may not close, has given up real optionality. That is what the reverse termination fee compensates, and it is why sellers press on the efforts covenant.

Public company mechanics, where applicable: proxy timing, shareholder votes that may need to be re-run, disclosure of the review's status, and the effect of a prolonged review on the stock.

And the deal team itself. People move on. A year into a review, the person who negotiated the merger agreement may be gone, and the institutional memory of why the efforts covenant reads as it does goes with them. Write it down at signing.

Step 10A — Working with staff, and reading the signals

The relationship with the investigating staff is a real variable, and it is managed rather than left to chance.

Know who is in the room. A line attorney, a supervisor, an economist, and — at decision points — the front office. Each cares about different things. The economist wants data and a coherent model; the line attorney wants documents and customer views; the front office wants a theory it can explain and, if necessary, try.

Ask what concerns them, and listen to the answer. Staff frequently say. A party that spends four months building a market definition defense when the concern is a vertical foreclosure theory has wasted the months.

Read the requests as signals. A follow-up focused on one tier means the theory has narrowed. A sudden interest in a third party's costs means a foreclosure theory. A request for a specific customer's contracts means that customer has said something.

Watch what the customers are doing. Agencies interview customers, and customers talk to the parties. A sales team reporting that "the government called and asked about us" is giving you the most valuable intelligence available in the investigation.

Be scrupulous about accuracy. A submission that is later shown to have been wrong — even innocently — costs more than the point it was making. Correct the record promptly and in writing when something turns out to be inaccurate.

Do not over-lawyer the meetings. Staff respond to the business people who actually know the market. A meeting in which the chief commercial officer explains how bids are won, with the data in front of her, does more than a deck delivered by counsel.

And know when the tone changes. A shift from open-ended questions to requests aimed at building a record is the signal that the staff recommendation is forming. That is the moment to make the best case and, if a remedy is needed, to bring it — not after the recommendation goes up.

Step 11A — How Brackenridge's eleven months ran

Weeks 1–3 (diligence). The overlap matrix showed a genuine problem in one product tier and nothing meaningful elsewhere. Win-loss data showed the two parties facing each other in roughly 70% of tier-one bids and facing three other suppliers in the rest.

Week 4 (diligence). The document assessment across eleven custodians found two problems: a board deck describing Corvallis as "the only supplier we consistently have to price against," and a synergy model line reading "margin recovery, reduced competitive intensity." Neither was written by anyone with pricing authority. Counsel built the context — the board deck sentence appeared in a discussion of one tier, and the synergy line had been removed from the final model at the chief financial officer's direction, which was documented.

Signing. Reasonable best efforts with a divestiture cap set by reference to the tier-one revenue, an eighteen-month outside date with two automatic extensions, and a reverse termination fee sized to the seller's estimated disruption cost. Delacroix-Sonnenfeld's note to the board: the cap was set at the number the overlap analysis said would be required, not at a number borrowed from a precedent deal.

Weeks 5–8. Filed, with the Part 803 documents and the prepared context. Cleared to the Antitrust Division. Voluntary staff meeting in week 6 presenting the business and the tier structure.

Week 8. Pull-and-refile requested and agreed.

Week 12. Second request issued: 38 custodians, five years, extensive transaction-level data.

Weeks 12–15. The negotiation that set the budget. Custodians reduced to 16, date range cut to three years for most categories, technology-assisted review protocol agreed with a validation sample, rolling production over four months. Estimated saving: $3.8 million and roughly seven weeks.

Weeks 15–34. Compliance and campaign, in parallel. Economic submission on diversion. Twenty-two customer conversations, documented, with no coaching. A rebuttal analysis showing that two suppliers had recently qualified at three of the largest accounts.

Week 34. Certification of substantial compliance, confirmed with staff first. Timing agreement: 75 days, three substantive meetings, front office access, ten days' notice before closing.

Weeks 36–42. The Division remained concerned about tier one and nothing else. Brackenridge proposed divesting the Corvallis tier-one line — formulations, two production lines, the technical service team, customer contracts, and a three-year supply agreement — to an identified upfront buyer, a mid-sized specialty chemical company entering the segment.

Week 44. Agreement in principle. Consent decree lodged, comment period run, judgment entered.

Total: eleven months from signing. About $11 million in antitrust cost, roughly $7 million of it second request compliance.

Delacroix-Sonnenfeld's three lessons: map the overlaps before the letter of intent, not after; find your own bad documents in week four; and treat the custodian negotiation as the budget decision it is.

Step 12 — Close, and then comply

Confirm the waiting period has expired or the decree has been entered, and that every other clearance is in hand.

Do not close early. The advance notice commitment in a timing agreement is a commitment, and closing in breach of it is the fastest way to convert a resolved matter into a contested one.

Then run the decree. Divestiture deadlines, buyer approval, transitional service obligations, monitoring, reporting, compliance certifications, and — where a crown jewel provision exists — the trigger date. Assign an owner with authority, calendar every obligation, and brief the business units that will actually perform them.

Complete the divestiture properly. A failed divestiture is worse than no remedy: it invites the agency back, it damages credibility for the company's next transaction, and it is the reason upfront buyer requirements exist.

And debrief. What did the review cost, what drove the cost, which documents caused problems, and what should the company do differently before the next deal. Companies that acquire regularly should be improving at this, and most are not because nobody writes it down.
