GAAP vs Non-GAAP: What You Need Before Talking to Lenders

Before you sit down with a lender or a buyer, you need two sets of numbers that agree with each other. The first is your financial statements prepared under GAAP. The second is the non-GAAP view, usually adjusted EBITDA, that shows what the business earns on a normal year.

Lenders and buyers will use both. They'll start from GAAP, then test every adjustment you made to get to the second number. If you've done that work first, the conversation goes much better.

This post is for owners of established manufacturers who are refinancing, adding debt, bringing in a partner, or thinking about a sale.

What does GAAP represent, and why do lenders trust it?

GAAP stands for generally accepted accounting principles. It's the standard rulebook for US financial statements. The main point for a manufacturer is that it uses the accrual basis: revenue when it's earned and costs when they're incurred, not when cash moves.

Lenders and buyers trust GAAP because it's consistent. Two manufacturers using GAAP should treat inventory, depreciation and revenue in comparable ways. That lets an outsider compare you to other companies and to your own prior years.

For a refresher on the basics, see what GAAP is and why it's needed.

Are your books actually on GAAP?

Many privately held manufacturers aren't fully on GAAP, and that's often fine for day-to-day use. The books may be on a cash basis, or on a tax basis, or somewhere in between.

The gaps that matter most in manufacturing are usually these:

• Inventory that doesn't include labor and overhead, so all overhead is expensed when spent. GAAP uses absorption costing, which puts a share of overhead into inventory.
• No work-in-process balance, or one that's only updated at year-end.
• Revenue recorded when invoiced instead of when the goods transfer, especially for tooling, deposits and bill-and-hold orders.
• Missing accruals for payroll, bonuses, utilities and vendor bills received late.
• No reserve for slow-moving or obsolete inventory.

There's also a tax point. Many companies under the gross receipts threshold of $32 million for 2026 can use simpler tax methods for inventory and accounting. Those are tax methods, not GAAP. A buyer or lender may still want GAAP numbers, so you may need both. This is general information, not tax advice; work with your CPA on which methods you use.

What does non-GAAP mean for a private manufacturer?

Non-GAAP means any measure that isn't defined by GAAP. For a private manufacturer, the common ones are EBITDA and adjusted EBITDA.

EBITDA is earnings before interest, taxes, depreciation and amortization. It's a rough proxy for operating cash earnings before capital spending and financing. Adjusted EBITDA goes further. It removes items that are personal to the owner, one-time, or not part of how the business will run under new ownership.

Public companies face SEC rules on how they present non-GAAP numbers. A private manufacturer doesn't. That's exactly why lenders and buyers check the adjustments themselves.

Why do companies use adjusted EBITDA at all?

Because GAAP net income for an owner-run company often doesn't reflect what a new owner or lender will see.

The owner may pay themselves well above or below market. Family members may be on payroll. The building may be owned by the owner and leased at a rate that isn't market. There may be a one-time lawsuit, a plant move or an unusual repair. None of that is wrong under GAAP. It just isn't a normal year.

Adjusted EBITDA tries to answer one question: what would this business earn in a normal year under normal ownership?

How does an adjusted EBITDA reconciliation look?

Here's an illustrative example for an S corporation manufacturer. Because it's an S corporation, there's no entity-level income tax line.

Line	Amount
GAAP net income	$1,200,000
Add interest expense	$150,000
Add depreciation	$400,000
EBITDA	$1,750,000
Add owner compensation above market rate	$180,000
Add one-time lawsuit and related legal fees	$70,000
Add payroll for family member not working in the business	$60,000
Subtract below-market rent on owner's building ($240,000 market less $120,000 paid)	-$120,000
Adjusted EBITDA	$1,940,000

Notice the last adjustment goes the other way. Honest add-backs include the ones that lower the number. A buyer will find the rent issue anyway. If you've already shown it, you look credible. If they find it, every other add-back gets a harder look.

The stakes are real. If a buyer values the business at a multiple of adjusted EBITDA, say 5x for illustration, that $120,000 rent adjustment is worth $600,000 of price.

Which add-backs hold up, and which get pushed back?

Add-backs that usually hold up have documentation and a clear reason they won't recur. Owner compensation backed by a market salary study. Personal expenses run through the business, with receipts. A legal settlement with a closed case file.

Add-backs that get pushed back tend to share a pattern. "One-time" costs that show up every year. Repairs added back because they felt unusual, when the equipment will keep needing them. Startup costs for a product line that is still losing money. Pro forma savings that haven't happened yet.

I think the safest test is simple: would you add it back if you were the buyer? If you'd argue against it from the other side of the table, take it out.

Our post on adjusted EBITDA goes deeper on the definitions.

What is a quality of earnings review?

A quality of earnings review, often called a QoE, is a report a buyer (and sometimes a lender) pays an accounting firm to prepare during diligence. It tests whether your adjusted EBITDA is real and repeatable.

For a manufacturer, the QoE team usually looks at:

• Each add-back and its support.
• Revenue cut-off: whether sales landed in the right month, especially around year-end.
• Inventory: counts, costing, overhead absorption, and obsolete stock.
• Gross margin trends by customer and product line.
• Customer concentration.
• Net working capital, meaning receivables plus inventory minus payables, and what a normal level looks like.

That last point matters at closing. Many deals set a target level of net working capital, often called a peg. If you deliver less at closing, the price can go down. If your monthly balance sheets are unreliable, the peg is hard to set fairly. Our post on what buyers look for in diligence covers the broader process.

How do lenders use EBITDA differently from buyers?

Lenders care about EBITDA because it drives covenant tests, like a minimum debt service coverage ratio or a maximum debt-to-EBITDA ratio.

The important thing is that the loan agreement defines EBITDA. It may allow some add-backs and cap or exclude others. Your covenant calculation has to follow the agreement's definition, not the one in your sales deck.

So keep one reconciliation and show which adjustments the bank allows. That way the owner, the lender and the CPA are looking at the same bridge.

Why do lenders and buyers want to see both?

GAAP shows what happened under consistent rules. Adjusted EBITDA shows what you believe the business earns normally. Neither one is complete alone.

If you only show adjusted EBITDA, the reader assumes you're hiding something in the GAAP numbers. If you only show GAAP, you leave value on the table for the owner-specific items that won't carry over.

The reconciliation between the two is where the trust comes from. Every line needs a short explanation and a document behind it.

How should you present GAAP and non-GAAP numbers?

Lead with the GAAP statements. Then show the reconciliation to EBITDA and adjusted EBITDA, line by line, for at least the last three years plus the trailing twelve months.

Use the same adjustments each year. If an item was added back in one year and not another, explain why. Keep a binder, physical or digital, with support for every adjustment.

Don't change your accounting methods right before a sale or a refinancing. A change might be correct, but it makes the trend harder to read and invites questions.

How can you get ready before the first meeting?

Ideally, you start a year or more ahead. Here's the order I'd follow.

1. Move the monthly books to accrual, with inventory costed consistently and a real work-in-process balance.
2. Reconcile every balance sheet account monthly.
3. Decide with your CPA whether you need reviewed or audited statements for the lender or buyer.
4. Build the adjusted EBITDA reconciliation now, with documents, and update it monthly.
5. Track net working capital monthly so you know what normal looks like.
6. Consider a sell-side quality of earnings review before going to market, if a sale is likely.

Our guide to getting your financials ready to sell has a fuller checklist.

Who should prepare this?

Your controller or fractional CFO should own the monthly GAAP books and the adjusted EBITDA bridge. Your outside CPA handles the review or audit and the tax side. We work alongside your CPA so the numbers tie out and nobody is surprised at diligence. See how we work with your CPA.

If a sale or refinancing is on the horizon, our fractional CFO work includes building and defending the reconciliation. The monthly close and GAAP books sit with our outsourced controller team.

Frequently Asked Questions

Do private manufacturers need GAAP financial statements?

Not always by law, but lenders and buyers often require them. Many bank loans ask for reviewed or audited statements prepared under GAAP.

What is the difference between EBITDA and adjusted EBITDA?

EBITDA adds back interest, taxes, depreciation and amortization to net income. Adjusted EBITDA also removes owner-specific and one-time items to show a normal year.

What add-backs do buyers usually accept?

Ones with documents and a clear reason they won't recur, like above-market owner pay or a closed legal settlement. Recurring "one-time" costs and pro forma savings usually get pushed back.

What is a quality of earnings report?

It's a diligence report that tests whether adjusted EBITDA is real and repeatable. For manufacturers it focuses heavily on inventory, revenue cut-off and working capital.

Can I use my own EBITDA definition for bank covenants?

No. The loan agreement defines EBITDA for covenant purposes. Follow its definition, and keep a reconciliation that shows the difference from your own view.
