The Rule That Changes Small Business Acquisition on October 1, 2026

On October 1, 2026, the rulebook that governs how American banks lend money to people buying small businesses changes more than it has in years. Most buyers have not read it. Most sellers do not know it exists. Every lender is scrambling. Here it is, concisely: what changed, why it matters, and what it does to the deal.

Some numbers first, because the scale is the point. The Small Business Administration's 7(a) program is the financing engine of Main Street acquisitions. In the fiscal year just ended, lenders wrote 7,533 change-of-ownership loans totaling $8.8 billion, up from $5.5 billion two years earlier: loan counts growing 22 percent a year and dollars growing faster than that, in a category most people have never heard of. Most of that money went to first-time buyers taking on a personal guarantee to buy a business from a retiring owner. For context, the largest online marketplace for these businesses reported 9,586 closed sales last year at a median price of $350,000, which tells you how much of the market runs through that one government program once a deal gets to real size.

The SBA's new operating procedure, SOP 50 10 8.1 if you want to sound like a lawyer or a banker, takes effect for every loan that receives an SBA loan number on or after October 1. It does four things a buyer needs to understand.

A business has to earn enough to cover its new debt payments 1.25 times over, using its actual historical earnings, not projections. Under the old rules the bar was 1.15x, and a persuasive story about growth could help clear it. Now the story is inadmissible: the test is run on the last fiscal year or a two-year average, and the lender is told in so many words that it may read the buyer's projections but may not rely on them. (The 1.15x bar survives only for an existing business buying another in its own industry.) If the numbers do not support the loan, the loan shrinks, or the price does.

That arithmetic is unforgiving. Moving the floor from 1.15x to 1.25x cuts the debt a given cash flow can support by about eight percent before anyone looks at the earnings themselves. A deal that penciled in September can fail in October with nothing changed but the calendar.

For any first-time acquisition or expansion with a business purchase price of $3 million or more (the price of the business itself, excluding real estate, and before seller financing or buyer equity reduce the loan), the lender must obtain a Quality of Earnings report, an independent analysis of what the business actually earns. Not a report the buyer ordered. Not one the seller commissioned to dress the business for sale. One the lender commissions, prepared for the lender's benefit, by an independent financial professional.

How many deals is that? Using the SBA's own loan-level data, 1,148 acquisition loans last year were large enough to have tripped this requirement (loans of $2.4 million and up, the usual financing on a $3 million purchase), and that slice is growing faster than the market around it: 644 such loans three years ago, 819 the year after, 1,148 last year. Roughly one acquisition loan in seven now carries a mandatory independent review, and the share is rising.

And the lender must use that report's earnings figure, not the seller's adjusted number and not the broker's recast, when it calculates whether the deal clears 1.25x. Every dollar the independent analysis removes from the seller's claimed earnings comes directly out of the maximum loan. For the first time, the seller's add-backs are not a negotiation. They are a finding.

The required analysis includes what the rule calls a Cash Proof: reconciling the bank statements to the income statement and the tax returns, for the trailing twelve months and each of the last two fiscal years. This is the single most powerful test in all of diligence, because a profit-and-loss statement can say anything, but deposits are deposits. The rule also spells out what else the report has to cover: every add-back and adjustment to the seller's earnings, including owner compensation, related-party transactions, deferred maintenance, and the gap between cash-basis and accrual books, plus customer concentration and whether existing revenue and margins survive the sale. Businesses whose reported revenue is not in the bank will have a much harder time being sold with SBA financing after October 1. That is exactly the point.

The cost of the lender's QoE passes to the borrower, though the rule allows it to count toward the buyer's required equity injection. Buyers will grumble. They should not. A first-time buyer is making the largest financial decision of their life, personally guaranteed, on the basis of numbers assembled by the person selling to them. The new rule forces the diligence a careful buyer would have wanted anyway, and puts an independent analyst between the seller's story and the bank's money.

Here is the change I think matters most, and the one I have seen the least written about. Under the old rules a lender could give a growing business credit for where it was going. A company doing $600,000 of earnings but on pace for $800,000 could, with a good story and a cooperative underwriter, be financed closer to the $800,000. That door is now closed. Coverage is tested on historical earnings, and on the independent analyst's version of them at that.

Think about what that does to a growth business. Senior debt is now sized to the trailing numbers, adjusted only for items the lender can document and defend in its credit memo. The growth is still real, and a buyer will still pay for it, but the bank will not. The difference has to come from somewhere else: more buyer equity, a bigger seller note, an earnout that pays the seller for the growth as it arrives. In other words, growth gets financed by the seller and the buyer, not by the lender. Sellers of fast-growing businesses should expect less cash at close and more paper. Buyers with equity to deploy, or sellers willing to carry, just gained an edge over the leveraged competition they used to lose to.

Two practical consequences follow. Timing becomes a tool: a business whose trailing twelve months are rising is worth more to a bank every quarter it waits, so the right moment to sign can be a quarter later than the right moment to agree. And the quality of the earnings analysis now sets the size of the loan directly, which means the analyst's judgment on every add-back has a dollar value the buyer and seller can both calculate. I will write a full issue on buying growth under the new rules; it deserves one.

Expect three things. Sellers and brokers will price deals at $2.9 million to duck the threshold; treat an asking price just under $3 million with a question mark unless the rationale is there. Expect multiple compression on marginal deals, because a financed buyer can now pay, at most, what the historical cash flow will service at 1.25x on a ten-year note plus whatever equity that buyer will stretch; growth stories can no longer be financed on narrative. And expect the smart buyers to run the 1.25x test themselves, before the LOI, so that the lender's report is a confirmation rather than a surprise. We built a free calculator for exactly that, adjusted to the new rules, at getworkup.ai/125x-test. Enter the deal, see the loan the numbers support, and drag the slider to watch what an independent review does to it.

That last habit is the whole lesson of the new rule, and it is the lesson this letter exists to teach: know what you are buying before you agree to buy it. The SBA has now written that principle into the financing of every larger deal in America. It was always the right way to buy a business. Now it is the required way. It is good for everyone at the table.

This is the work Workup does. For buyers, we verify the numbers and give you an investor's read on what the business is worth, before the LOI, so you know whether a deal clears 1.25x before the bank's report decides it for you. For lenders, the same analysis comes in the compliance form the rule now requires, in five business days, independent and insured. If you have a deal in the pipeline that October changes, reply to this email and tell me about it. I read every reply, and the next issue will be built from what you send.

P.S. Two doors, depending on which side of the table you sit on. Buyers: run the last deal you looked at through the calculator. If it clears 1.25x, you learned something about the seller's numbers; if it does not, you learned something about how the deal was priced. Either way you learned it for free and before the bank did. Lenders: under delegated authority the report has to be under an engagement letter at the moment the loan number issues, so the provider list needs to exist before the deal does. If you are assembling yours before October, reply with one word and I will send you our sample report and the engagement letter.
