There is a dangerous moment in a business acquisition when the financing starts to work.

The seller wants $2.5 million.

I have $500,000.

The lender says it can provide $1.4 million.

The seller agrees to carry $600,000.

The spreadsheet balances.

And for about thirty seconds, the deal feels solved.

It is not.

All I have proved is that I can assemble enough money to close.

I have not proved that the business can carry the debt after I own it.

Those are very different things.

This is the part of acquisition financing that interests me more than the down payment. I already looked at how much money you actually need to buy a business in Canada. That is fundamentally a capital-stack question: buyer equity, senior debt, vendor financing, transaction costs, working capital and liquidity.

This article asks the harder question:

How much acquisition debt can the company itself safely support?

Not how much the bank will lend.

Not how much debt I can cram into the transaction.

Not how much leverage produces the prettiest return on equity.

How much debt can the business repay while still behaving like a healthy business?

That distinction matters because debt can do something extraordinary in an acquisition.

It lets me buy an asset much larger than my own equity cheque, and then lets the acquired company use its future cash flow to repay part of my purchase price.

That is one of the most powerful wealth-creation mechanisms available to an individual investor.

It is also capable of destroying a perfectly good business.

The same leverage that turns $500,000 into control of a $2 million company can turn a 20% earnings decline into a liquidity crisis.

So I would not ask:

What’s the maximum debt this deal can support?

I would ask:

What’s the maximum debt this deal can support after I assume something goes wrong?

That is a much more useful number.

Debt Capacity Starts With Earnings — But Not the Seller’s Number

Suppose a business is marketed with:

SDE: $600,000

The seller works full time.

His spouse does bookkeeping.

His brother handles some sales on an under-market salary.

There are several aggressive add-backs.

If I simply divide acquisition debt by $600,000, I can make the leverage look wonderfully conservative.

But perhaps after normalizing:

• owner’s replacement salary,
• family payroll,
• recurring expenses,
• questionable add-backs,

the business really produces:

$400,000 of owner-independent EBITDA

That is a radically different debt base.

This is why the SDE vs EBITDA question comes before acquisition financing.

I do not want to finance a business against earnings that disappear when the seller leaves.

Debt survives closing.

Add-backs sometimes do not.

The Lender May Think in EBITDA Multiples

Acquisition lenders often express debt capacity as a multiple of EBITDA.

BDC’s business acquisition financing guide gives an example where a senior lender is willing to lend three times EBITDA, while the rest of the transaction is filled with other capital such as vendor debt and mezzanine financing.

That is a useful way to frame leverage.

Suppose normalized EBITDA is:

$500,000

Then:

• 1× EBITDA debt = $500,000
• 2× = $1,000,000
• 3× = $1,500,000
• 4× = $2,000,000

Easy.

But this ratio tells me surprisingly little by itself.

A company with $500,000 EBITDA and almost no capex can support more debt than a company with the same EBITDA that needs $200,000 of machinery every year.

A recurring-revenue company with stable margins can support more leverage than a cyclical project business.

A diversified company can support more than one where a single customer represents 45% of sales.

A business with $800,000 of excess working capital may have options a cash-starved business does not.

So debt/EBITDA is a starting point.

It is not the answer.

EBITDA Does Not Repay Principal

This is one of the most important things to keep straight.

EBITDA is useful because it strips out:

• interest,
• taxes,
• depreciation,
• amortization.

But debt principal is paid with cash.

And the business has other claims on cash before I get comfortable sending everything to the bank.

Suppose:

Normalized EBITDA: $500,000

Now subtract:

• cash taxes: $60,000
• maintenance capex: $75,000
• incremental working capital: $35,000

Cash available before acquisition debt service:

$330,000

That is already 34% below EBITDA.

If I size the acquisition debt as though the full $500,000 is available, I am financing an accounting approximation rather than the company.

This is why I increasingly want three numbers when evaluating a business:

1. Seller SDE.
2. Buyer-normalized EBITDA.
3. Buyer-normalized free cash flow.

The debt is ultimately serviced by number three.

Debt Service Coverage Ratio

The standard bridge between earnings and debt is the debt service coverage ratio, or DSCR.

A simplified version is:

Cash Flow Available for Debt Service ÷ Principal and Interest Payments

BDC’s DSCR guide notes that lenders use debt-service coverage as a key measure of creditworthiness and debt capacity. BDC presents a common calculation using EBITDA divided by annual principal and interest, while also noting that interpretation varies and the inputs matter.

For acquisition underwriting, I would go further than a mechanical EBITDA calculation.

I want to know what cash is actually available after the recurring expenditures required to keep the company producing that EBITDA.

Suppose:

• normalized EBITDA: $500,000
• annual principal + interest: $250,000

Simple DSCR:

2.0×

That looks strong.

But suppose the company also requires:

• $80,000 annual maintenance capex,
• $50,000 cash taxes,
• $40,000 recurring working-capital investment.

Adjusted cash available:

$330,000

My practical coverage is closer to:

1.32×

Same company.

Same debt.

Very different comfort level.

This is why I would always ask what definition of DSCR is being used.

Ratios are only useful if I know what is inside them.

A 1.0× DSCR Is Not a Business Plan

At 1.0× coverage, essentially every dollar available under the chosen calculation is required for debt service.

There is no margin.

BDC’s DSCR discussion makes the obvious but important point that a ratio around 1 is much less healthy because little is left for taxes, reinvestment or distributions. BDC says there is no universal hard-and-fast threshold, although it describes 2× or higher as generally healthy in its basic framework.

I would not turn 2× into a universal acquisition rule.

Different lenders calculate coverage differently.

Different businesses deserve different margins.

But the principle is right:

The closer debt service gets to the company’s real cash generation, the more I am betting that nothing goes wrong.

Things go wrong.

The Acquisition Has Two Debt Questions

I separate debt into two questions.

Question 1: How Much Can the Business Borrow?

This is the lender question.

It depends on:

• EBITDA,
• assets,
• historical cash flow,
• customer quality,
• industry,
• guarantees,
• collateral,
• buyer strength,
• covenants.

Question 2: How Much Should I Let the Business Borrow?

This is my question.

It depends on all of the above plus:

• my downside assumptions,
• desired distributions,
• growth plans,
• maintenance capex,
• working-capital volatility,
• transition risk,
• personal risk tolerance,
• how much liquidity remains after closing.

The bank’s maximum is a ceiling.

It is not a target.

A $2 Million Business at Three Different Debt Levels

Suppose I am buying a business for:

$2,000,000

Normalized EBITDA:

$500,000

Assume for simplicity:

• maintenance capex: $60,000
• cash taxes before financing effects: $50,000
• normalized annual working-capital growth: $30,000

That leaves roughly:

$360,000

before acquisition debt service.

Now compare three capital structures.

Structure A — Conservative

Senior acquisition debt:

$750,000

Assume annual principal and interest:

$150,000

Practical cash coverage:

2.4×

Cash remaining after debt service:

$210,000

That gives me room for:

• distributions,
• extra debt repayment,
• growth investment,
• surprises.

Structure B — Moderate

Senior acquisition debt:

$1,250,000

Annual debt service:

$240,000

Coverage:

1.5×

Cash remaining:

$120,000

Still workable.

But there is less room.

Structure C — Aggressive

Senior acquisition debt:

$1,600,000

Annual debt service:

$315,000

Coverage:

1.14×

Cash remaining:

$45,000

The transaction closes.

The debt gets paid.

The business has almost no room to breathe.

That is not the capital structure I want.

Now Let EBITDA Fall 20%

This is where the financing decision becomes real.

EBITDA falls from:

$500,000 → $400,000

Maybe there is a recession.

Maybe the seller was unusually good at sales.

Maybe the largest customer delays a program.

Maybe margins normalize.

Maintenance capex is still:

$60,000

Taxes may fall somewhat.

Working-capital needs may change.

Suppose adjusted cash available for debt service falls to:

$280,000

Now:

Structure A

Debt service: $150,000

Coverage:

1.87×

Still comfortable.

Structure B

Debt service: $240,000

Coverage:

1.17×

Uncomfortable, but potentially manageable.

Structure C

Debt service: $315,000

Coverage:

0.89×

The business cannot cover scheduled debt service from operating cash.

Nothing catastrophic happened.

EBITDA fell 20%.

That is an entirely ordinary business event.

The aggressive capital structure turned it into a financing event.

That is exactly what I want to avoid.

Good Businesses Have Bad Years

This seems obvious when written down.

It becomes less obvious during an acquisition.

The CIM shows five years of growth.

The broker talks about pipeline.

The seller explains why next year will be even better.

The lender sizes debt against normalized earnings.

Everybody is looking forward.

I want to look sideways.

What did the worst historical year look like?

What happens if it repeats?

What happens if revenue falls 15%?

What if gross margin falls three points?

What if the largest customer disappears?

What if the seller’s replacement takes six months longer than expected?

The debt payment does not care why EBITDA missed the forecast.

It is still due.

Debt Service Is Fixed. Business Earnings Are Not.

This is the fundamental mismatch.

A company may produce:

• $600,000 EBITDA one year,
• $475,000 the next,
• $700,000 the year after.

Debt service may remain:

$250,000 every year

That fixed claim is what creates leverage.

When earnings rise, equity gets the upside.

When earnings fall, debt does not volunteer to share the pain.

This is why stable companies can support more leverage than volatile ones even if their average EBITDA is identical.

Two $500,000 EBITDA Businesses

Consider:

Company A

Five-year EBITDA:

• $470,000
• $490,000
• $510,000
• $500,000
• $530,000

Average:

$500,000

Company B

Five-year EBITDA:

• $250,000
• $700,000
• $350,000
• $800,000
• $400,000

Average:

$500,000

Same average EBITDA.

I would not put the same debt on them.

Company A behaves like an annuity.

Company B behaves like a weather system.

Debt should be sized against the downside, not the average.

Customer Concentration Should Reduce Debt Capacity

Suppose a company generates:

$600,000 EBITDA

One customer represents:

40% of revenue

The customer has been there for fifteen years.

The seller says the relationship is excellent.

Wonderful.

I still have a 40% customer.

If that account disappears after closing, the effect on EBITDA may be much larger than 40% because fixed overhead remains.

Perhaps $600,000 EBITDA becomes:

$250,000

Now imagine I financed the acquisition based on three times $600,000:

$1.8 million of debt

The business did not become bad overnight.

The capital structure became impossible.

Customer concentration is not merely a valuation issue.

It is a debt-capacity issue.

That is why it deserves its own article later in this series.

Owner Dependence Should Reduce Debt Capacity Too

The same is true of seller dependence.

Suppose the seller personally:

• handles the top ten customers,
• prices every large quote,
• approves purchasing,
• recruits key employees,
• knows every machine,
• manages the bank.

The financial statements show $500,000 EBITDA.

But some portion of that cash flow is attached to a human being who is leaving.

I should not lever the business as though the organization owns all of it.

The more owner-dependent the earnings, the less confident I am in the first two years of debt service.

This is another reason the owner dependency test matters before financing.

Acquisition Debt and Operating Debt Are Different

A business may already require debt to operate.

For example:

• operating line for receivables,
• inventory financing,
• equipment loans,
• vehicle leases,
• mortgages.

Then I add acquisition debt.

These obligations all compete for the same cash.

Suppose the company has:

$500,000 EBITDA

I add:

$1.2 million acquisition term debt

But the company also needs:

• $500,000 operating line,
• $250,000 equipment loan,
• several leases.

The acquisition debt is not the entire leverage picture.

I care about total fixed claims.

The company needs enough capacity not only to buy itself but to continue being itself.

Working Capital Can Quietly Consume Debt Capacity

This connects directly to net working capital in a business acquisition.

Suppose the business grows revenue by 20%.

Great.

EBITDA rises from:

$500,000 → $600,000

But NWC is 15% of revenue.

Growth requires another:

$150,000

of receivables and inventory net of payables.

The entire $100,000 EBITDA increase plus another $50,000 disappears into working capital.

If my acquisition debt was sized assuming growth would quickly improve coverage, I may have exactly the opposite experience.

The company becomes more profitable and more cash constrained at the same time.

Growth can make debt harder to service before it makes it easier.

Maintenance Capex Is Debt Service’s Competitor

This is especially important in manufacturing, transportation, construction and asset-heavy service businesses.

A company may report:

$700,000 EBITDA

Excellent.

But it owns:

• CNC machines,
• trucks,
• forklifts,
• compressors,
• production equipment.

Depreciation is added back in EBITDA.

The machines do not care.

They still wear out.

If sustainable maintenance capex is:

$200,000 a year

I do not have a $700,000 cash-flow business.

I have something closer to a $500,000 pre-tax cash-flow business before working capital and financing.

This is why EBITDA can dramatically overstate debt capacity in capital-intensive businesses.

The Capex Trap

Imagine two businesses at:

$500,000 EBITDA

Business A — Service Company

Maintenance capex:

$25,000

Business B — Machine Shop

Maintenance capex:

$175,000

Before taxes and working capital:

• A produces roughly $475,000 after maintenance capex.
• B produces roughly $325,000.

Same EBITDA.

A may support materially more acquisition debt.

Unless, of course, B’s equipment provides enough collateral and stability to offset part of the cash-flow disadvantage.

This is why acquisition underwriting is not one ratio.

It is a system.

Seller Financing Is Still Debt

A VTB can make an acquisition much easier to close.

BDC describes vendor financing as a common component of acquisition packages and notes that it can reduce the buyer’s upfront cash requirement and preserve liquidity. Its vendor financing guide also notes that vendor debt is commonly junior to senior bank financing and may have more flexible repayment terms.

All good.

But a seller note is not free equity.

It is debt.

Suppose:

• senior debt: $1 million
• VTB: $600,000
• buyer equity: $400,000

Purchase price:

$2 million

I might say the business has only $1 million of bank debt.

Economically, it has:

$1.6 million of acquisition debt

The VTB may be patient.

It may be subordinated.

Principal may be deferred.

Those features make it safer.

But eventually someone expects the $600,000 back.

I need to model that.

Patient Debt Can Support More Total Debt

This is where debt structure matters as much as debt amount.

Compare two $1.5 million debt packages.

Package A

• $1.5 million senior loan
• five-year amortization
• full principal immediately

Package B

• $1 million senior loan
• $500,000 VTB
• VTB interest-only for two years
• principal repaid later
• subordinate to senior lender

Same total debt:

$1.5 million

Completely different first-two-year cash burden.

That matters because the transition period is often the riskiest part of an acquisition.

BDC has specifically emphasized preserving liquidity during the ownership transition and notes that vendor financing can be structured more patiently than conventional bank debt.

I would happily pay a somewhat higher interest rate for debt that matches the cash-flow risk of the transition.

Cheap debt with the wrong amortization can be more dangerous than expensive patient debt.

Amortization Can Matter More Than Interest Rate

Suppose I borrow:

$1 million

Loan A

• 6% interest
• 5-year amortization

Loan B

• 8% interest
• 10-year amortization

Loan B costs more interest.

But its annual required principal payment is dramatically lower.

If my priority is surviving the first three years, Loan B may create a safer company.

I am not saying I would automatically choose it.

Longer amortization means debt remains outstanding longer and total interest is higher.

But acquisition debt should be evaluated by:

• rate,
• amortization,
• principal holidays,
• balloon payments,
• covenants,
• prepayment rights,
• security,
• guarantees.

Interest rate is one line in the agreement.

Cash-flow flexibility is the product.

The Balloon Payment Problem

A VTB can look wonderfully affordable because principal is deferred.

Suppose:

$500,000 seller note

Terms:

• 7% interest
• interest-only for five years
• entire $500,000 due at maturity

Annual cash burden:

$35,000

Easy.

Year five:

$500,000

Less easy.

If my model simply assumes I refinance the balloon, I have made a financing assumption about a future lender, future interest rates and future business performance.

Maybe that is reasonable.

But I want to see the balloon on the acquisition model in large red numbers.

Deferred debt is still debt.

It has simply moved the problem into the future.

Covenants Can Make Debt Feel Larger

Loan agreements can require more than payments.

BDC’s guide to loan covenants explains that lenders can impose financial and operating conditions, including maintaining specified ratios or restrictions on additional debt and other actions.

Suppose my company has enough cash to:

• pay the bank,
• pay the VTB,
• make a $150,000 distribution to me.

But the credit agreement prohibits the distribution because DSCR or leverage falls outside the permitted range.

Economically, that debt is more restrictive than the payment schedule alone suggests.

I care about:

• minimum DSCR,
• maximum debt/EBITDA,
• restrictions on distributions,
• additional borrowing,
• capital expenditures,
• acquisitions,
• owner compensation.

I am not just borrowing money.

I am selling the lender a degree of control over the balance sheet.

Personal Guarantees Do Not Increase Business Debt Capacity

This distinction matters.

Suppose the business itself safely supports:

$1 million

of acquisition debt.

The lender says:

We’ll lend $1.3 million if you personally guarantee it and pledge additional assets.

Have I increased the company’s debt capacity?

No.

I have increased the lender’s recovery options.

The business still generates the same cash.

The extra $300,000 may make the transaction financeable.

It does not make the company better able to pay.

This is why I would not confuse:

bank willingness to lend

with:

business ability to service debt

A guarantee protects the bank from my downside.

It does not protect me from it.

The HELOC Can Hide Leverage Outside the Company

Suppose:

• purchase price: $2 million
• acquisition-company debt: $1 million
• VTB: $500,000
• buyer equity: $500,000

Looks like:

2× senior debt / EBITDA

if EBITDA is $500,000.

But I borrowed my entire $500,000 equity cheque on a HELOC.

My economic debt stack is now:

• $1 million senior acquisition debt,
• $500,000 VTB,
• $500,000 personal HELOC.

Total debt supporting the acquisition:

$2 million

I technically contributed equity to the acquisition company.

My household did not.

Again:

Borrowed equity is debt wearing a different jacket.

I would model leverage at both levels.

The Debt-Free Seller Can Make the Business Look Safer Than It Is

This is another acquisition trap.

The seller has owned the company for thirty years.

No bank debt.

Lots of cash.

He tells me:

We’ve never had trouble paying our bills.

Of course not.

The company has no acquisition debt.

Then I buy it and put:

$1.5 million

of debt on the same cash flow.

I am not buying the seller’s financial resilience.

I am replacing it with my capital structure.

A historically debt-free business can become highly leveraged on closing day without one thing changing operationally.

Past stability does not validate my future leverage.

Excess Working Capital Can Hide the Same Problem

A debt-free founder may have accumulated:

• excess inventory,
• slow receivables,
• large cash balances,
• conservative supplier practices.

That can make the company feel incredibly liquid.

After closing, cash may be stripped under a cash-free/debt-free transaction.

The NWC peg may deliver only normalized working capital.

Then acquisition debt is added.

The company I own can have a much tighter balance sheet than the company I diligenced.

That is not necessarily wrong.

It is simply another reason to model the post-closing balance sheet, not admire the historical one.

What Would I Consider a Safe Debt Level?

I do not think there is one universal multiple.

But I would build a debt-capacity range using four tests.

Test 1 — Normalized EBITDA

What are sustainable earnings after replacing the owner and removing questionable add-backs?

Test 2 — Normalized Free Cash Flow

What remains after:

• maintenance capex,
• taxes,
• recurring working-capital needs?

Test 3 — Downside Cash Flow

What happens if EBITDA falls:

• 10%,
• 20%,
• 30%?

Test 4 — Transition Cash Flow

What happens if I incur:

• extra management cost,
• one-time integration expenses,
• delayed customer payments,
• emergency capex?

The debt amount that survives all four is much more interesting to me than the amount a lender initially quotes.

A Practical Debt-Capacity Example

Suppose I am evaluating a manufacturing company.

Historical normalized economics

• Revenue: $5 million
• EBITDA: $650,000
• Maintenance capex: $125,000
• Cash taxes: $75,000
• Normalized working-capital investment: $50,000

Approximate cash available before acquisition debt service:

$400,000

Base Case Debt

Senior debt:

$1.5 million

VTB:

$500,000

Total acquisition debt:

$2 million

Suppose annual payments are:

• senior principal + interest: $300,000
• VTB interest: $35,000
• VTB principal deferred

Initial annual debt service:

$335,000

Practical coverage:

1.19×

I do not like it.

The spreadsheet works.

The company is fragile.

Better Structure

Senior debt:

$1.2 million

VTB:

$500,000

Buyer equity increases by:

$300,000

Senior annual debt service falls to perhaps:

$245,000

VTB interest remains:

$35,000

Total:

$280,000

Coverage:

1.43×

Better.

Still not luxurious.

Now suppose the seller agrees to defer VTB interest for the first year.

Debt service:

$245,000

Coverage:

1.63×

Now I have something I can work with.

Same business.

Same purchase price.

The capital structure changed the risk dramatically.

Now Stress-Test It

EBITDA falls 20%:

$650,000 → $520,000

Suppose cash available after capex, taxes and working capital falls to:

$310,000

First-year debt service:

$245,000

Coverage:

1.27×

Not fun.

But survivable.

If I had used the original $335,000 debt-service structure:

Coverage:

0.93×

Now I am finding money somewhere else.

This is the number I want before I sign the LOI.

Debt Capacity Should Reflect the Business Model

I would generally tolerate more leverage in a business with:

• recurring revenue,
• diversified customers,
• low capex,
• predictable margins,
• low owner dependence,
• strong management,
• low working-capital volatility.

I would tolerate less in:

• project businesses,
• cyclical industries,
• customer-concentrated companies,
• commodity-sensitive businesses,
• capital-intensive operations,
• turnarounds,
• owner-dependent companies.

This is not revolutionary finance.

It is simply matching fixed obligations to cash-flow reliability.

A Distributor Can Be More Leveraged Than It Looks — Or Less

Distribution is a good example.

A distributor may have:

• substantial inventory,
• receivables,
• supplier credit,
• modest capex.

EBITDA may convert well to cash in a steady state.

That can support debt.

But growth may consume huge amounts of working capital.

A 25% sales increase can require:

• more inventory,
• more receivables,
• larger operating line.

If I finance the acquisition aggressively and then grow aggressively, the company can run out of cash while reporting record profits.

That is why I would model growth separately from the base acquisition debt.

A Machine Shop Can Have the Opposite Problem

A machine shop may have:

• equipment collateral,
• relatively modest working capital,
• attractive margins.

A lender likes the machines.

But maintenance and replacement capex can be significant.

If the previous owner delayed replacing two CNC machines before selling, historical EBITDA may overstate sustainable free cash flow.

I buy the company.

Six months later I need:

$500,000 of equipment

The lender says:

Congratulations on the acquisition.

This is why equipment condition belongs in debt underwriting.

Deferred capex is debt I have not borrowed yet.

Deferred Maintenance Is a Hidden Liability

This concept extends beyond machinery.

Suppose a business needs:

• roof replacement,
• fleet renewal,
• ERP upgrade,
• cybersecurity work,
• environmental remediation.

None of those necessarily appear as debt on the closing balance sheet.

But if I know I will spend $300,000 during the first two years, that is a claim on cash just like debt service.

I would reduce acquisition debt capacity accordingly.

The company does not care whether the cheque says:

Loan Principal

or:

Replace Machine #4

Cash is cash.

Growth Capex Is Different

I distinguish maintenance capex from growth capex.

Maintenance capex keeps current earnings alive.

Growth capex is intended to create new earnings.

That matters.

I should absolutely subtract maintenance capex when determining sustainable debt capacity.

Growth capex is more discretionary.

But if my acquisition thesis requires $400,000 of growth investment immediately after closing, then it is not really discretionary to my plan.

I need room for it.

A capital structure that leaves no money to execute the acquisition thesis defeats the purpose of buying the company.

This Is Why Maximum Leverage Can Reduce Returns

It sounds backwards.

More leverage should increase return on equity.

Mathematically, yes.

Operationally, perhaps not.

Suppose aggressive debt prevents me from:

• hiring a sales manager,
• buying a productive machine,
• expanding inventory,
• acquiring a competitor,
• launching a new product.

I saved $300,000 of equity at closing.

Then I starved a business capable of creating $2 million of incremental value.

That is not efficient capital allocation.

Debt is supposed to amplify the asset.

It should not suffocate it.

Debt Paydown Is Part of My Return

This is the positive side.

Suppose I invest:

$600,000

into a $2.4 million acquisition.

The company takes on:

$1.8 million

of acquisition debt.

Five years later debt is:

$900,000

Even if enterprise value remains exactly $2.4 million, my equity has grown from:

$600,000 → $1.5 million

before distributions.

The company paid down:

$900,000

of debt using operating cash flow.

That value accrued to me.

This is why I like acquisition debt.

It can convert business cash flow into equity without requiring a higher valuation multiple.

The trick is surviving long enough for amortization to work.

Debt Amplifies EBITDA Growth Too

Suppose the same company starts at:

• EBITDA: $600,000
• multiple: 4×
• enterprise value: $2.4 million
• debt: $1.8 million
• buyer equity value: $600,000

Five years later:

• EBITDA: $800,000
• same 4× multiple
• enterprise value: $3.2 million
• debt: $900,000

Equity value:

$2.3 million

My $600,000 has become $2.3 million before distributions.

Two things happened:

1. Enterprise value grew by $800,000.
2. Debt fell by $900,000.

Both accrued to equity.

That is why acquisition leverage can be so powerful.

And why I am willing to use it.

I simply do not want to maximize it.

The Asymmetry Is the Problem

If EBITDA grows from $600,000 to $800,000, debt service does not rise proportionately.

I get the upside.

If EBITDA falls from $600,000 to $400,000, debt service does not fall proportionately either.

I get the downside.

Leverage makes equity more volatile.

That is fine if I am being paid for it.

It is dangerous if I mistake the base-case spreadsheet for a guarantee.

The First Two Years Deserve More Margin

I would probably tolerate less debt at acquisition than I might after owning the business for several years.

Why?

Because immediately after closing I know the least.

I do not yet know:

• which customers are truly loyal,
• which employees are flight risks,
• where the hidden expenses are,
• what the seller quietly did every day,
• whether normalized EBITDA was really normalized,
• how much inventory is actually obsolete,
• which machines are temperamental.

After three years, I may know the business intimately.

At closing, I have diligence.

Those are not the same thing.

Transition risk deserves a financing margin.

Vendor Debt Can Absorb Some Transition Risk

This is where I particularly like seller financing.

Suppose the seller carries:

$500,000

with:

• no principal for two years,
• interest accrued rather than paid,
• subordination to senior lender.

Economically, that behaves more like patient capital during the riskiest period.

Later, when the company has stabilized, it becomes normal debt.

That is a much better match between financing and risk.

It also keeps the seller economically connected to the quality of the business he sold me.

I would rather have a $500,000 patient VTB than squeeze another $500,000 of fully amortizing senior debt into the company just to reduce my equity cheque.

The Bank’s Covenant Case Is Not My Downside Case

A lender will stress the business.

I still want my own model.

The lender is trying to answer:

Will we get repaid?

I am trying to answer:

Will I still like owning this company after everyone gets repaid?

Those are different standards.

A lender can be made whole while my equity return is terrible.

A lender can have security over assets.

I own the residual.

My downside model should be harsher.

I Want to Know the Debt-Free Cash Flow

One useful exercise is to ignore acquisition financing entirely.

Ask:

If this company had no acquisition debt, how much cash would it sustainably generate for its owner?

Suppose:

• EBITDA: $600,000
• maintenance capex: $100,000
• taxes: $80,000
• normalized working-capital growth: $40,000

Debt-free cash flow:

$380,000

Now I decide how much of that $380,000 I am comfortable committing to lenders.

At:

$150,000 debt service

I have $230,000 left.

At:

$250,000

I have $130,000.

At:

$350,000

I have $30,000.

That framing is much more intuitive to me than starting with a leverage multiple.

I can see what I am giving up.

Then Ask What the Leftover Cash Has to Do

The cash after debt service is not necessarily mine.

Perhaps it needs to fund:

• growth,
• management hires,
• equipment,
• dividends,
• emergency reserve,
• bolt-on acquisitions.

Suppose my acquisition thesis is:

I can grow this business from $5 million to $8 million of revenue.

Great.

What does that growth consume?

If it needs $500,000 of working capital and $300,000 of equipment, I need cash.

A debt structure that captures every dollar of free cash flow may make the thesis impossible.

The right debt capacity depends partly on what I intend to do after closing.

A Lifestyle Buyer and Growth Buyer May Choose Different Debt

Two buyers acquire the same company.

Buyer A

Wants:

• stable income,
• modest growth,
• aggressive debt paydown.

Buyer B

Wants:

• new locations,
• equipment,
• acquisitions,
• 20% annual growth.

Buyer A may tolerate higher scheduled debt repayment because excess cash is destined for debt anyway.

Buyer B needs liquidity.

Same company.

Different optimal capital structure.

There is no financing structure independent of strategy.

Refinancing Is Upside, Not the Base Case

A common acquisition model says:

We’ll refinance in year three.

Maybe.

If EBITDA grows and leverage falls, refinancing can:

• lower rates,
• extend amortization,
• repay seller debt,
• release capital.

Excellent.

But I would not make the acquisition dependent on a future lender solving today’s overleveraged structure.

Credit markets change.

Rates change.

The business may miss plan.

I want the original financing to work on its own.

Refinancing should improve a good deal.

Not rescue a bad one.

The Canada Small Business Financing Program Has Limits

For smaller transactions, the federal Canada Small Business Financing Program can help finance eligible business assets and working-capital costs through participating financial institutions.

As of 2026, the program allows up to $1.15 million in total financing: up to $1 million in term loans plus up to $150,000 in a line of credit, subject to important sub-limits and eligibility rules.

But there is a crucial acquisition distinction.

The program is designed around eligible assets and costs.

It does not mean the government will simply finance $1.15 million of whatever purchase price the seller and I agree on.

Shares themselves are not an eligible expenditure under the program.

This is another reason purchase structure and asset composition affect financeability.

Government-backed financing can help.

It does not repeal cash-flow underwriting.

Debt Capacity Is Not Purchase-Price Capacity

This deserves to be said plainly.

Suppose a business safely supports:

$1 million of acquisition debt

I have:

$500,000 equity

Seller will finance:

$300,000

That gives me:

$1.8 million

of capital.

It does not mean the business is worth $1.8 million.

Maybe it is worth:

$1.5 million

Then I should pay $1.5 million.

The extra financing capacity stays unused.

One of the easiest ways to overpay is to let the capital stack determine valuation.

Financing tells me whether I can execute the price.

It does not determine the price.

Purchase Multiple and Debt Multiple Are Different

Suppose:

• EBITDA: $500,000
• purchase price: $2.5 million
• purchase multiple: 5×
• senior debt: $1 million
• VTB: $500,000
• equity: $1 million

Total acquisition debt:

3× EBITDA

Purchase multiple:

5× EBITDA

Those are separate ratios.

The business may be conservatively financed but expensively purchased.

Or:

• purchase price: $2 million = 4×
• debt: $1.75 million = 3.5×

Now I may have bought at an attractive valuation but financed it aggressively.

Good price does not guarantee good financing.

Good financing does not guarantee good price.

I need both.

My Acquisition Debt Checklist

Before accepting the financing structure, I would want to answer:

1. What is buyer-normalized EBITDA?
2. What is sustainable free cash flow after maintenance capex?
3. What recurring working-capital investment is required?
4. What does annual senior principal and interest equal?
5. What are the VTB payments?
6. Are any payments deferred?
7. Are there balloon payments?
8. What happens at 10%, 20% and 30% EBITDA declines?
9. What happens if the largest customer leaves?
10. What capex is likely in the first three years?
11. What liquidity remains after closing?
12. What operating debt does the company already require?
13. What covenants restrict distributions or investment?
14. What personal guarantees am I giving?
15. Am I using personal debt to fund the equity cheque?
16. Does the financing leave enough cash to execute my growth plan?
17. Can the deal survive without refinancing?
18. How quickly does debt amortize if the base case works?

If I cannot answer those, I do not know the leverage.

I only know the loan amount.

The Maximum Debt Is the Wrong Target

Suppose the bank will lend:

$1.5 million

The business can probably survive with:

$1.5 million

But it would thrive with:

$1.1 million

Which should I choose?

That depends on what the extra $400,000 of equity costs me.

If putting in another $400,000:

• materially lowers risk,
• preserves growth capital,
• lets me sleep,
• prevents covenant pressure,

perhaps it is excellent capital allocation.

If that $400,000 is my last liquid capital and leaves my family financially exposed, perhaps not.

The point is that the answer is not automatically:

Use all available debt because debt is cheaper than equity.

Equity is expensive.

Financial distress is more expensive.

I Do Not Want to Buy a Good Business and Give It a Bad Balance Sheet

This is probably the simplest way I can put it.

Imagine a company that has operated successfully for thirty years.

It has:

• loyal customers,
• good employees,
• healthy margins,
• no financial stress.

I buy it.

To minimize my equity cheque, I load it with:

• senior acquisition debt,
• a large VTB,
• a maxed operating line,
• aggressive amortization.

Six months later the company is still operationally excellent.

But I cannot:

• replace equipment,
• invest in growth,
• tolerate a customer delay,
• make a distribution.

I did not improve the business.

I financialized it into fragility.

That is not the objective.

The Business Should Become Safer Every Year

The capital structure I like has a natural direction.

At closing:

• leverage is highest,
• uncertainty is highest.

Then:

• debt amortizes,
• I learn the business,
• customer relationships transfer,
• seller dependence falls,
• cash reserves grow,
• EBITDA hopefully grows.

Every year, the acquisition should become less fragile.

That is a beautiful structure.

The opposite is one where:

• principal balloons later,
• capex is deferred,
• VTB comes due,
• working capital is stretched,
• refinancing becomes mandatory.

That structure may become more fragile with time.

I want to know which one I am buying.

How Much Debt Can a Small Business Acquisition Actually Support?

The answer is not:

2× EBITDA.

Or:

3× EBITDA.

Or whatever a lender is willing to quote.

Those can be useful reference points.

But the real answer is:

The business can support the amount of debt whose principal and interest it can pay through a realistic downside scenario while still funding taxes, maintenance capex, working capital and the investments required to keep the company healthy.

That number will be different for every company.

For one $500,000 EBITDA business, perhaps $1.5 million of debt is perfectly sensible.

For another, $750,000 may already be aggressive.

The difference is not the EBITDA.

It is everything underneath it.

What I Would Optimize For

I want enough leverage that the acquisition is worth doing.

Debt should:

• reduce my required equity,
• let company cash flow build my ownership,
• improve return on equity,
• preserve some of my personal capital for other uses.

But I want enough equity that a bad year remains a bad year.

Not an existential event.

That is the balance.

I am not afraid of acquisition debt.

Quite the opposite.

It is one of the things that makes buying a business so attractive.

A company can use its own future cash flow to help pay for my ownership of it.

There are not many assets where I can personally influence the earnings, finance a substantial portion of the purchase price and then have the asset itself amortize the debt.

That is powerful.

But the power comes from surviving the leverage.

If I put $500,000 into a $2 million company and five years later the business has paid $750,000 of debt down for me, that is fantastic.

If I save $200,000 of equity at closing by maximizing debt and then lose the company during a 20% earnings decline, the return on equity was technically spectacular right up until it became negative 100%.

I would rather own slightly less leverage and substantially more optionality.

The bank’s maximum loan is interesting.

The business’s maximum safe loan is the number I actually care about.
