By 2035, about six million small and medium-size businesses (SMBs) will face ownership transitions as baby boomers retire, according to McKinsey Institute for Economic Mobility's February 26, 2026 report, "The Great Ownership Transfer: A New Era of Business Stewardship." By 2040, 22% of the U.S. population will be at retirement age, up from 19% in 2025 and 12% in 2005. Who buys those businesses — and how the transition is financed — will shape jobs, local wealth, and retirement outcomes.
The Scale
- 6 million transitions by 2035. The wave is not just family businesses; it spans owner-operated SMBs where the owner is the operator and the business is the retirement asset.
- 92% involve seller financing. McKinsey and commentator Seller Edge Capital both highlight that 92% of small-business transfers in recent samples involved seller-financed notes — the seller becomes the bank because conventional buyers cannot close otherwise.
- Stranded capital. Seller notes are often 5-to-10-year, low-liquidity instruments. The owner who financed the sale holds a note that cannot be spent, borrowed against easily, or diversified — a persistent financing gap the private-credit market is now targeting.
Why Transitions Stall
Three frictions repeat:
- No succession plan. A majority of owners have no written plan. When retirement, health, or burnout forces a sale, the business hits the market underprepared — financials not diligence-ready, customer concentration undisclosed, owner dependence unaddressed.
- Buyer financing gap. SBA 7(a) covers some deals, but many fall into the gap between SBA limits and conventional bank appetite for goodwill-heavy SMBs. Seller financing fills the gap and creates the stranded-note problem.
- Valuation and workforce risk. Buyers discount businesses with high owner dependence or thin management. McKinsey notes the ownership transfer is also a workforce transfer — retaining key employees through the transition preserves value more than any purchase-price adjustment.
What Owners Should Do in 2026
- Start the three-year clock now. Diligence-ready financials (3 years of accrual-basis statements, customer concentration disclosure, owner add-backs documented) and a management team that can operate without the owner add measurable enterprise value.
- Model seller-financed proceeds as a portfolio. A $1M note at 7% for 8 years is a fixed-income asset with credit risk concentrated in one buyer. Price it accordingly and consider note-sale or participation options — Seller Edge Capital's thesis is that liquidating a portion of seller notes de-risks the seller's retirement concentration.
- Engage advisers early. Retirement-plan advisers, as PLANSPONSOR notes, have an opportunity to connect succession planning to retirement readiness — because for many SMB owners, the business sale funds retirement.
