Roll-ups usually fail for four reasons: they pay too much, borrow too much, fail to integrate what they buy, or issue too much stock. As of October 2026, a study of 6,000+ IPO registrations found that, among newly public firms, stock-paid acquisitions underperformed cash deals by 20–30 percentage points over 3–5 years and were about 50% more likely to end in delisting. One public example: MBH Corporation, a UK holding company of about 19 small businesses, delisted in January 2024 and entered administration the next month.
A roll-up makes money on the gap between what it pays for small companies and what the combined company is worth. Every turn of multiple you overpay comes straight out of that gap.
Overpaying usually happens in one of three ways:
Competition makes this worse. In HVAC, PKF O'Connor Davies counted 25 tracked deals in the first half of 2026, and 14 were private equity add-ons. Those buyers often have cheaper capital and will pay more than you should.
SBA coverage ratios are minimums for making a loan, not targets for running a company. Under SOP 50 10 8.1, an Initial Acquisition needs 1.25x debt service coverage and a Business Expansion needs 1.15x, both on historical cash flow. Seller debt not on full standby counts in that test at a maximum 10-year amortization.
Debt is dangerous in a roll-up because problems arrive together. An integration stalls, a key manager leaves and a rate resets in the same year. SBA loans require personal guarantees from owners of 20% or more, so a failed roll-up can follow the owner home. Keep coverage well above the lender's floor and stress-test a bad year before you sign.
Integration is where the arbitrage becomes real or disappears. It fails for ordinary reasons:
Even good programs lose some deals. In our best client outcome, which was not a typical one, the founder made three acquisitions over seven years. One failed and was closed. The company still went on to sell for $240M in cash.
Stock lets a roll-up buy without cash, but each share issued gives away part of every future dollar of profit. Castellum, listed on NYSE American, paid more than 80% of a roughly $6.6M acquisition in restricted stock. Its share count rose from about 53M to about 94.6M between March 2024 and March 2026.
The academic data points the same way. Completing an IPO raised a firm's annual probability of making an acquisition by about 12 percentage points, and about three-quarters of those extra deals were at least partly paid in stock. Those stock-paid deals were the ones that underperformed.
Assume an add-on earning $1M of EBITDA, a platform the market values at 6.5x, and debt at 10%, the maximum SBA variable rate for loans over $350,000 in September 2026 when prime was 7%. Check current prime; rates move. The 20% earnings drop is an assumption.
A disciplined price absorbs a bad year. An inflated price plus debt does not.
Where these numbers come from: stock-as-currency findings from the CLS Blue Sky Blog (July 14, 2026); MBH Corporation from TheBusinessDesk; Castellum share counts from jwatte.com; GF Data medians via Carry and Conquer; HVAC deal counts from PKF O'Connor Davies; SBA rules via Cantrell Law; SBA rates from NerdWallet; earnout data (SRS Acquiom) via Livmo; deal costs from Big Deal Small Business.
Not if it is contained. Keep each company in its own entity, avoid cross-guarantees where you can, and size each deal so one loss is survivable. Close a failing company early rather than funding it indefinitely.
Yes, and usually for the same reasons, especially debt. Private equity firms have more capital and staff, but leverage magnifies their mistakes as well. Size does not protect a roll-up from overpaying.
They carry extra risks: dilution, the cost of being public and a share price that can fall below what you need to keep issuing stock. They also have advantages, such as a currency sellers can sell. See public vs private roll-up math.
There is no reliable dataset that ranks causes for small roll-ups. Overpaying combined with debt is arguably the most dangerous mix, because it leaves no room for the integration problems that almost always come.
Most overpaying starts with a misunderstanding of what small companies and platforms really trade for. Next, read what's the multiple difference between an add-on and a platform?
