Mergers and Acquisitions Advisory Case Studies
Finance5 Case StudiesUpdated Sep 2026
These five cases follow advisory teams through the stretch of deal work where the numbers stop agreeing with each other. Each one begins with a problem inside a fictional company and walks through what the team found, what it decided, and what followed. The mechanics are the ones practitioners meet during diligence, financing, and post-close review. Watch how each team set its thresholds before reading the results, and notice where the evidence was thin. Several cases end without a clean answer, which is usually the honest outcome.
Case Study 1
Ledger gap surfaces during a sell-side reconciliation
Sorrel Point Logistics, a regional freight forwarder with four depots and roughly 260 employees, preparing its first outside sale.
The situation
Caldera Hale's advisory team was preparing Sorrel Point for a sale to a strategic buyer. The company's management had closed the prior fiscal year with audited statements, but the buyer's diligence group wanted monthly reconciliations for the trailing twelve months. In the third week of the process, the team pulled the accounts receivable subledger, the general ledger control account, the bank statements for the two operating accounts, and a sample of customer confirmations. The subledger totaled $14.2 million, the control account showed $13.7 million, and the bank statements did not map cleanly to either figure. The gap was small relative to revenue but large enough to block a clean working capital peg.
The challenge
The variance was not one error. Some of it looked like timing, with cash applied in the bank before the subledger picked it up, and some looked like duplicate postings from a billing migration that had run during the spring. The team had to isolate each component, document it with evidence, and decide how much unexplained balance the buyer would accept before the price adjustment became a negotiation. Management wanted the number closed in one week.
Analysis
Teams grounded in Mergers and Acquisitions Advisory usually start by separating reconciling items from errors before they touch the balance. The team built a bridge with three columns: timing items that cleared within the expected lag, items with a traceable source document but no matching entry, and items with no support at all. Each bridge line was tied to a bank reference, an invoice number, or a credit memo. Anything that could not be tied went to the unsupported column with a dollar value and an owner. The discipline here is refusing to net unsupported items against timing items, because netting hides the number that matters.
The team set its threshold before reading the bridge closely. Under the draft purchase agreement, a working capital shortfall above 150,000 dollars would move the peg, and a variance under 40,000 would be absorbed as normal close noise. Between those two figures, the parties would negotiate. The control evidence mattered as much as the amount. The team asked for the cutoff procedure, the posting approval log, and the bank reconciliation sign-offs for each month. Two of the three months had sign-offs dated after the period was closed, which meant the controls existed on paper but were applied late. That finding changed how much weight the team gave management's explanations.
- Third weekSubledger, control account, and bank totals pulled and compared.
- Days laterBridge built with timing, traceable, and unsupported columns.
- Same weekApproval log showed sign-offs dated after period close.
- End of fourth weekSeller support received for two thirds of unsupported items.
- Final settlementPeg adjusted by $55,000 and controls redesigned.
Actions taken
- Rebuild the bridge from source documents rather than from management's summary, and tag every line as timing, traceable, or unsupported before anyone discusses the total.
- Ask the seller for a written explanation of each unsupported item, with an owner and a date. Anything still open at the end of the week enters the peg calculation at full value.
- Test the controls that failed the timing test: pull the posting approval log for the three months, match every late sign-off to its period close, and record the exceptions in a single schedule.
- Propose a post-close control: a monthly three-way match between subledger, control account, and bank, with a fixed sign-off window of five business days and an escalation to the controller if it slips.
Results
The bridge was closed in the second week of the revised timetable. Of the $500,000 gap, about $340,000 traced to timing items and documented postings, leaving $160,000 unsupported. The seller produced support for roughly two thirds of that remainder, and the parties settled on a peg adjustment of $55,000. The negotiation ran shorter than the original schedule allowed. The control redesign went into the buyer's close calendar, and the first monthly three-way match finished inside its window. Management attributed the late sign-offs to staffing, but the approval log pointed to an older habit.
Questions for discussion
- Which of the three bridge columns would you have been least comfortable netting, and why?
- How should the team have set the peg thresholds if the seller had refused to produce any support?
- What evidence would convince you that a control had changed behavior rather than just changed on paper?
Case Study 2
Shrinking margins test a sale process forecast
Ashcombe Mills, a textile finishing company with two plants, roughly 640 employees, and a customer base concentrated in apparel brands.
The situation
Ashcombe Mills had planned for a steady year of revenue growth ahead of a sale process. Midway through the year, two anchor customers cut orders after a retail season went soft, and a supplier of dye chemicals raised prices twice within a quarter. Monthly revenue ran about 9 percent under the plan, gross margin fell by roughly four points, and operating cash flow turned negative in two consecutive months. The advisory team had built the original model with a board-approved base case, and the lender covenant reset depended on trailing twelve-month EBITDA. The sale timetable had not moved, so the team needed a forecast that a buyer could test.
The challenge
The year had already missed plan. The harder question was which of the misses would persist into the next twelve months and which would reverse once the retail season turned. Management's own forecast assumed a recovery in the second half that depended on two new contracts not yet signed. A buyer's diligence team would pull the same monthly actuals, so any scenario that leaned on unsigned revenue would be discounted, and the seller would lose credibility on the rest of the model.
Analysis
Start with the records rather than the narrative. The team rebuilt the monthly actuals from the sales ledger, the purchase ledger, and the payroll register, then tied the totals to management accounts. The variance on revenue was mostly volume, concentrated in two accounts that together carried about 31 percent of billings. Margin pressure came from dye costs and from a freight surcharge that had been booked to overhead instead of cost of sales. Each driver then got a persistence estimate. Risk exposure sat mainly in the two accounts, where a single further order cut would move covenant headroom past the reset point.
Thresholds had to be fixed before the scenarios reached the board. The team set three triggers: trailing EBITDA below the covenant reset level for two consecutive months, gross margin under 19 percent for a full quarter, and cash on hand below 2,500,000 dollars. Each trigger linked to a specific action, such as drawing the revolver, pausing a capital project, or opening talks with the lender about a waiver. The control evidence was the monthly close package, the customer order file, and written supplier price notices. The team did not accept verbal assurances from sales about pending orders, and it marked every unsigned contract as zero in the base case.
Actions taken
- Build three scenarios: a base case with signed revenue only, a recovery case with the two pending contracts at a haircut, and a downside case with one more account cutting orders.
- Rerun the covenant test under each scenario and identify the month in which headroom disappears, then bring that date to the lender before it arrives rather than after.
- Fix the freight surcharge reclassification in the close package, restate the two prior months, and show the board both the reported and corrected margin so the trend is not distorted by presentation.
- Pre-agree the three triggers with the board and the lender, assign an owner to each action, and review the trigger status at every monthly close, recording any change in the decision log.
Results
The board adopted the middle scenario and agreed to revisit it at each close. The lender agreed to an early discussion of a temporary covenant adjustment, once the restated margins were in hand. Two of the pending contracts later signed, but at prices below the recovery case, so the buyer's model was built on the downside assumptions for the account mix. The sale process continued on schedule, at a narrower valuation range than management had hoped. The response held up because each figure in the forecast could be traced to a signed document or a supplier notice.
Questions for discussion
- Which of the three triggers would you have been most reluctant to pre-agree with the lender, and what would change your mind?
- If the recovery case had been built on verbal assurances from sales, how would the board discussion have differed?
- How should a seller weigh a credible downside case against the risk that buyers anchor on it?
Case Study 3
Unusual payment routing halts an acquisition timetable
Pennick Harbor Holdings, a family-owned holding company that owns three marine equipment distributors, with roughly 1,200 employees across two countries.
The situation
Pennick Harbor was buying a distributor of marine equipment, and the target's revenue had grown quickly over two years through a small group of export customers. During confirmatory diligence, the advisory team noticed that roughly 22 percent of receipts arrived through three third-party payment intermediaries not named in the customer contracts. Several of the paying entities had registered addresses that matched a shared service office, and two had been incorporated within the same few weeks. None of this proved wrongdoing, but the pattern met the buyer's internal list of warning indicators. The deal team had planned to sign within the month, and the seller's counsel was already drafting the disclosure schedule.
The challenge
The team had to decide whether the indicators were explained by ordinary commercial arrangements or whether the buyer would be inheriting exposure it could not quantify. The documentation was thin. Payment instructions were verbal in several cases, and the intermediaries had no written service agreements. A delay of several weeks would strain the seller's financing, and a walk away would cost the buyer its exclusivity period. Someone had to say which way the evidence pointed.
Analysis
Begin with the records that would show where the money went. The team matched 310 receipts from the three intermediaries to invoices, bank credits, and shipping documents. About 70 percent tied cleanly. The rest either lacked a shipping document or showed a shipment consigned to a different party than the paying entity. Exposure was sized in two ways: the gross value of unmatched receipts over the last three years, and the amount of revenue whose counterparties could not be confirmed. The second figure was the one that concerned the buyer's counsel, because it set the scope of any indemnity and the size of the escrow the lenders would require.
The escalation rule in the buyer's policy was specific. Any counterparty that could not be verified against the target's own customer master file, or any payment route that lacked a written agreement, required referral to the compliance committee before signing. The team did not treat the referral as a verdict. The control evidence requested included the target's onboarding files for the intermediaries, its sanctions screening logs, and the approval history for the new routes. Two of the three intermediaries had onboarding files with the same reviewer initials, and the screening log showed no hits on either. That was reassuring but incomplete, because screening only covers names, not ownership chains.
- Detect Flag routes, counterparties, or timing that fall outside normal patterns.
- Assess Size exposure using matched and unmatched values, not gross receipts.
- Escalate Refer the item to the compliance committee with documented evidence attached.
- Remediate Set closing conditions, escrow, and termination of unverifiable routes.
Actions taken
- Trace the ownership of each intermediary and the paying entities through public registry filings and the target's own records, and write down every beneficial owner the team could not identify.
- Refer the three intermediary routes to the compliance committee as a formal item, with the matched and unmatched receipt totals attached, and ask for a decision on continuation before any signing date is set.
- Size the indemnity and escrow against the unconfirmed revenue figure, not the gross receipts, and ask the seller to fund a specific escrow for any route that remains unverified at the signing date.
- Require the seller to terminate payment routes that cannot be documented, and add a closing condition that the buyer's compliance office receives a clean screening report on every named counterparty before funds move.
Results
The committee asked for a three-week extension and approved signing on the condition that the two unverified routes be closed before funds moved. One intermediary was terminated by the seller. The other could not produce ownership documents and was dropped from the revenue base, which reduced the valuation by a figure the seller disputed for most of a month. The deal closed with a narrower price but without an open exposure that the buyer could not describe. The compliance file now shows each decision, the evidence behind it, and the date each condition was met.
Questions for discussion
- At what point would you have stopped treating the shared service office as a coincidence?
- How much weight should a clean screening log carry when the screening covers names but not ownership?
- Should the buyer have walked away once the seller resisted the ownership requests, and what would that have cost?
Case Study 4
Expansion loan request from a tile manufacturer
Marrowby Tile Company, a family-controlled maker of commercial tile and fixtures with two plants and about 430 employees.
The situation
Marrowby Tile wanted 18 million dollars to fund a third kiln line and a distribution contract with a national builder. The company had grown revenue steadily for several years, but its margins were thin and its customer base was concentrated in two builders who accounted for about 46 percent of sales. The owners offered a secured term loan with a personal guarantee and proposed to pledge the existing plant equipment and receivables. The lending committee had asked the advisory team to evaluate the request, test the cash flow under a downside, and recommend approval terms or a decline. The request arrived in the middle of a period when the builder segment had slowed, so the timing was not neutral.
The challenge
The committee wanted to know whether the company could service the debt if both went wrong together. The committee's concern was not the purpose of the loan but the order of events. The kiln line would take nine months to commission, and the distribution contract did not start paying until the line was running at volume. Interest and principal would begin before the new revenue existed. A downside in the builder segment would hit the existing business at the same time as the project was absorbing cash.
Analysis
The team rebuilt cash flow from the last audited statements and the monthly management accounts. It separated maintenance capital from discretionary spending, because the existing kilns had a service schedule that would not move. The base case assumed the new line reached 80 percent utilization by the end of the first year after commissioning. The downside cut builder volume by 20 percent, extended the commissioning period by one quarter, and held the distribution contract price flat. Under that combination, debt service coverage fell below 1.0 in two of the first four quarters. The base case cleared the covenant with modest room, so the decision depended entirely on the downside.
Suitability turned on the owners' tolerance for a personal guarantee against a business whose largest customers could change their orders quickly. The guarantee covered 40 percent of the loan. The lender's policy required collateral coverage of at least 1.2 times on the equipment and receivables, and the appraisal cleared it only if the receivables from the two builders remained current. The team set the approval conditions around three things: a debt service reserve funded at closing, a covenant on builder concentration below 35 percent of sales by the second year, and a restriction on dividends until coverage stayed above 1.3 for four consecutive quarters.
Actions taken
- Approve only with a debt service reserve equal to six months of payments, funded from the loan proceeds at closing, so the first slow quarter does not force a covenant conversation.
- Cap the project draw schedule so that each tranche is released only after the kiln line reaches a defined commissioning milestone, verified by an independent engineer and not by management's internal report.
- Require monthly reporting of builder receivables aging and order backlog, with a trigger that moves the loan to enhanced monitoring if either the top two customers fall below agreed levels for a quarter.
- Decline the request as structured if the owners will not accept the reserve and the builder concentration covenant, and offer to revisit a smaller first phase tied to the existing contract.
Results
The committee approved a reduced facility with a first tranche of 9 million dollars and a conditional second tranche tied to commissioning. The owners accepted the concentration covenant but negotiated a longer cure period than the team had proposed. Two quarters later, a builder cut orders for a season, and the enhanced monitoring trigger was reached in the third quarter after closing. The company drew on the reserve without a covenant breach, and the second tranche was held until the kiln milestone was verified by the independent engineer. The file records the downside case alongside the outcome.
Questions for discussion
- Would you accept a personal guarantee of this size from owners whose other holdings are tied to the same industry, and why?
- How should the committee price the risk that the builder concentration covenant is cured by a single large new customer?
- What would make you approve the second tranche before the kiln milestone was verified?
Case Study 5
Control gaps found in a pre-sale audit review
Vellmar Industrial Supply, a distributor of pumps and valves with three warehouses and about 1,900 employees, owned by a private equity fund.
The situation
Vellmar Industrial Supply was preparing for a sale, and the sponsor asked the advisory team to run a pre-sale review of the controls that would support the buyer's financial diligence. The review covered revenue recognition, inventory counts, purchase order approvals, and the journal entry process at the corporate close. Field work took about six weeks. The review identified a set of weaknesses that were individually modest but collectively significant: rebates accrued without support, inventory adjustments approved by the same person who recorded them, and manual journal entries posted after the close calendar had locked. The sponsor wanted a findings list it could share with the buyer, with a credible remediation plan.
The challenge
Not every finding carried the same weight. A rebate accrual that was unsupported by 18,000 dollars could be corrected in a single entry. A segregation failure over inventory adjustments, on the other hand, meant that the inventory balance itself could not be relied on until the counts were redone. The team had to rank findings by their effect on the reported numbers, assign owners who could actually fix them, and define what evidence would show each fix had worked.
Analysis
Materiality was judged against the figures the buyer would use. The team took the inventory balance of 41 million dollars and the rebate accrual of about 6.5 million as the anchor figures. An inventory adjustment control that could move the balance by up to 2 percent of its value ranked above a rebate gap of similar dollar size, because the rebate gap was bounded by contract terms while the inventory one was not. Findings were scored on exposure, reach into reported figures, and persistence. The journal entry weakness ranked high on persistence, since manual postings after lock appeared in most months of the review window.
Owners were assigned by authority over the process, not by who had complained most loudly. The inventory adjustment approval belonged to the distribution controller, who could separate the recording and approval duties within a week. The rebate accrual belonged to the commercial finance manager, who had to obtain signed rebate agreements for each supplier. Closure was defined as evidence, not assertion. For the rebate finding, closure required signed agreements for every accrued supplier and a rerun of the accrual schedule. For the journal entry finding, closure required a clean lock report for three consecutive closes with no post-lock entries lacking a second approver.
Actions taken
- Rank the findings in a single schedule with dollar exposure, reach into reported figures, and persistence, and agree the ranking with the sponsor before any remediation work starts.
- Separate the recording and approval duties for inventory adjustments in the system, and pull every adjustment made in the review window to confirm whether any was approved by its own preparer.
- Require a second approver for every manual journal entry posted after the lock date, and have the controller sign a monthly exception report that lists each one with its business reason.
- Obtain signed rebate agreements for every accrued supplier, rerun the accrual schedule against them, and correct any difference in the period it is found rather than carrying it forward.
Results
Management closed the rebate and journal entry findings within the remediation window, and the inventory separation was live before the next count. The rebate rerun corrected an accrual by about 310,000 dollars, which was recorded in the period it was found and disclosed to the buyer with the supporting agreements. The lock report showed three clean closes, which satisfied the closure test. The inventory finding took longer because the counts had to be repeated at two warehouses. The sponsor shared the full findings list with the buyer, who asked for the closure evidence rather than the summary.
Questions for discussion
- How would your ranking change if the buyer weighted persistence more heavily than dollar exposure?
- What closure evidence would you accept for the inventory finding if the counts could not be repeated?
- Should the owner of a control be the person most affected by its failure, or the person best placed to fix it?
