Quillfield Mechanical: M&A Case Study with Answer

The deal makes sense if Sablecrest's standalone value plus the synergies Quillfield can realistically capture, minus integration costs, is comfortably above the price. So I would answer three questions: what is Sablecrest worth on its own, what is it worth to Quillfield specifically, and how much of that extra value can we afford to hand to the sellers given the risks.

I would value Sablecrest by segment, because a maintenance contract, a repair call and a fixed-price installation project are very different businesses with different margins, growth and multiples.

• Standalone value: revenue and EBITDA by segment, growth, quality of the contract base, comparable deal multiples.
• Synergies: cost (overlapping branches, purchasing, back office), revenue (selling Quillfield services to Sablecrest customers), one-time integration costs, and dis-synergies such as customers lost when branches close.
• Price: asking price vs standalone value, share of synergies paid away, what the competing bidder can afford, and how Quillfield funds it.
• Risks and integration: customer concentration, founder-held relationships, technician retention, project execution, systems and culture.

What the interviewer is looking for

• Good: covers standalone value, synergies, price and risks.
• Strong: frames the decision as standalone value plus net synergies vs price, and plans to value the segments separately.
• Excellent: asks early who else is bidding and what they can pay, because a buyer without synergies sets the floor of the negotiation.

Push-back: Why not just apply one industry multiple to Sablecrest's $14.4 million of EBITDA and be done with it?

Segment EBITDA is $9.0 million from maintenance (18% of $50M), $4.8 million from repair (12% of $40M) and $0.6 million from projects (2% of $30M), which adds up to the $14.4 million total.

Maintenance contracts are 42% of revenue but 62.5% of EBITDA, and they are the fastest-growing segment at 6% a year. Installation projects are 25% of revenue but only about 4% of EBITDA, and they are shrinking. So Sablecrest is really a maintenance business with a low-margin project arm attached.

Because the profitable segment grows fastest, EBITDA should grow about 4.5% next year at constant margins, roughly twice the 2.25% revenue growth. The value of this deal rests on the maintenance contract base, so renewal rates and who owns those customer relationships are the first things to diligence.

What the interviewer is looking for

• Good: computes segment EBITDA and sees that maintenance carries the business.
• Strong: compares share of revenue with share of EBITDA and links growth to the segment mix.
• Excellent: notes that EBITDA grows faster than revenue because of mix, and turns the finding into diligence priorities (renewals, relationships, project risk).

Push-back: Projects barely make money. Should Quillfield ask the sellers to carve them out of the deal?

Valuing each segment at its own multiple: maintenance $9.0M x 12 = $108.0M, repair $4.8M x 9 = $43.2M, projects $0.6M x 6 = $3.6M. Standalone value is about $154.8 million, or about $155 million.

That is a blended 10.75x EBITDA. The asking price of $180 million is 12.5x EBITDA, which is above even the maintenance-contract multiple, and about $25 million above standalone value. Quillfield can only justify that premium with synergies.

What the interviewer is looking for

• Good: applies multiples to EBITDA and lands near $155 million.
• Strong: values segment by segment instead of one blended multiple, and states the asking price as 12.5x.
• Excellent: points out that 12.5x is above the best segment's multiple, so the sellers are already pricing in a buyer's synergies.

Push-back: The banker says Sablecrest deserves 12x across the board because HVAC services are hot. What do you say?

Cost synergies: branches 4 x $0.9M = $3.6M, purchasing 6% of $40M = $2.4M, back office 50% of $3.0M = $1.5M, so $7.5 million a year. The controls cross-sell is 160 customers x $25,000 = $4.0M of revenue, worth $1.2 million of EBITDA at 30%. Total run-rate synergies are $8.7 million.

At 8x, cost synergies are worth $60 million, or $51 million after the $9 million integration cost. The cross-sell would add $9.6 million, but it is untested, so I would treat it as upside and not pay for it.

Value to Quillfield is $154.8M + $51M = about $206 million, which is the walk-away price. At $180 million Quillfield would pay a $25.2 million premium, handing the sellers about 49% of the net cost synergies it has to work to deliver.

What the interviewer is looking for

• Good: sizes the four levers correctly and gets about $8.7 million of run-rate synergies.
• Strong: separates cost from revenue synergies, nets out the one-time cost and gets a walk-away price near $206 million.
• Excellent: refuses to pay for the untested cross-sell and frames the $180 million price as the share of synergies given to the sellers.

Push-back: The value is $206 million and the price is $180 million. That looks like $26 million of free money. Why not just sign?

The cushion at $180 million is thin. Value to Quillfield is about $205.8 million, so the price leaves $25.8 million for things that go wrong. Two risks alone could eat most of it.

Customer concentration: the largest customer is 9% of revenue, or $10.8 million, worth $1.9 million of EBITDA at 18%. Losing it at the 2027 re-tender would cost about $23.3 million of value at 12x, leaving a cushion of only $2.5 million. The founders own the top relationships and are leaving, which makes this more likely.

Synergy delivery: if Quillfield delivers 70% of cost synergies, as in a typical deal, net synergies fall to $33 million and value to $187.8 million, a cushion of $7.8 million.

People and projects: technician turnover is 24% vs 16% at Quillfield, and technicians are the scarce asset in this business. One in three fixed-price projects runs over budget, so the project arm can turn a $0.6 million profit into a loss.

• Offer $165 million upfront plus an earn-out of up to $15 million over two years, paid only if the county contract is renewed and maintenance renewals stay at 88% or higher. The upfront price gives the sellers about 20% of net cost synergies instead of 49%.
• Use the competing bidder as leverage: a private equity fund without local synergies can justify about $155 million, so Quillfield does not need to match the full ask upfront.
• Fund a technician retention pool of about $1.9 million ($5,000 x 380) before closing, and keep the founders on paid transition contracts for the top 20 accounts.
• In diligence, review every open fixed-price project and stop bidding fixed-price jobs below a set margin.

What the interviewer is looking for

• Good: names customer concentration, founder relationships and technician turnover as risks.
• Strong: puts dollar values on the biggest risks and compares them with the cushion at the asking price.
• Excellent: turns the risks into deal terms (earn-out, retention pool, founder transition) and uses the synergy-less rival bidder as negotiating leverage.

Push-back: If Quillfield offers less than the ask, the private equity fund may win. Are you comfortable losing the deal?

Buy Sablecrest, but not at $180 million upfront. Offer $165 million in cash plus up to $15 million in earn-out tied to renewing the county contract and keeping maintenance renewals at 88% or higher.

Sablecrest is worth about $155 million on its own, driven by a maintenance business that earns 62.5% of its EBITDA and grows 6% a year. Cost synergies of $7.5 million a year add about $51 million after integration costs, so the deal is worth about $206 million to us. At the full $180 million we would give the sellers half of those synergies and keep a $26 million cushion that losing the largest customer alone would almost wipe out.

The rival bidder has no synergies, so we can hold firm. Before signing we need to diligence the county contract and the project overruns, and lock in technician retention and a founder transition.

What the interviewer is looking for

• Good: gives a clear yes or no with a price.
• Strong: backs it with standalone value, synergy value and the cushion at the asking price.
• Excellent: offers a deal structure that shares the risk with the sellers and names what would make Quillfield walk away.

Buy Sablecrest, but do not pay $180 million upfront: offer $165 million in cash plus up to $15 million in earn-out tied to renewing the largest customer and keeping maintenance renewals at 88% or higher.

Standalone, Sablecrest is worth about $155 million (segment multiples on $14.4 million of EBITDA, 62.5% of it from maintenance contracts). Cost synergies of $7.5 million a year are worth about $51 million after $9 million of integration cost, so the deal is worth about $206 million to Quillfield.

At $180 million Quillfield would hand the sellers about half of those synergies and keep a $25.8 million cushion, which losing the largest customer ($23 million of value) would almost erase. The private equity bidder has no synergies and should not go much above $155 million, so Quillfield has room to negotiate.

Next steps: diligence the county contract and the 35% project overrun rate, set a $1.9 million technician retention pool and founder transition contracts before signing, and treat the $1.2 million controls cross-sell as upside, not price.
