Lower Middle Market M&A in March 2026: Recovery, Uncertainty, and a Lot of Dry Powder

The lower middle market M&A environment entering March 2026 is full of contradictions.

On paper, almost everything points to a strong year. Buyer confidence is near a multi-year high.

There is more uninvested private equity capital sitting on the sidelines than at almost any other point in history.

Deal supply hit a record in 2025. And yet, completed lower middle market transactions remain well below peak levels, the Iran conflict that erupted in late February introduced fresh macro uncertainty, and SBA lending (the lifeblood of smaller acquisitions) is contracting sharply.

Here is what you actually need to know if you are actively sourcing, buying, or selling a business in the $5M to$100M enterprise value range right now.

Confidence is high. Closings are not.

Axial tracked a record 12,856 deals coming to market in 2025, up 17.1% year-over-year. Meanwhile, GF Data counted only 297 completed PE-sponsored transactions for the full year, a 23% decline from 2024, and 41% below the 2021 peak. More deals marketed. Fewer deals closed. That gap is the story of the LMM right now.

The reasons are not hard to find. Capstone Partners reports that middle market valuation multiples have sat in a compressed 9.0x–9.5x EV/EBITDA band since 2023, well below the historical mean of 10.8x. GF Data puts the average PE-sponsored LMM deal at 7.2x trailing EBITDA for 2025. Sellers who remember 2021 still want 2021 prices. Buyers who are living with all-in borrowing costs of roughly 8.5% cannot pay them. The valuation gap is real, but it is narrowing.

That said, the sentiment numbers are hard to ignore. Deloitte's 2026 M&A Trends Survey of 1,500 corporate and private equity leaders found that 90% of PE respondents expect deal numbers to increase in 2026, and 87% expect higher aggregate deal values. Citizens Bank data shows middle market PE confidence surged from 48% at the start of 2025 to 86% by Q4. And the IBBA Market Pulse Q4 2025 survey found 72% of business brokers expect 2026 conditions to meet or exceed the 2021 peak. That is as optimistic as the intermediary community gets.

There is no shortage of capital, the problem is deploying it.

Global private equity dry powder sits at roughly $2.18 trillion, down from a mid-2024 peak of $2.62 trillion as deployment accelerated. U.S. PE dry powder has dropped more sharply to approximately $880 billion from a record $1.3 trillion in late 2024, a 32% decline, which tells you deals are getting done, just not as fast as the capital stacked up.

Compounding the dry powder story: Bain & Company estimates there are roughly 32,000 unsold PE-backed companies worth $3.8 trillion waiting for exits. PE firms returned only about 14% of AUM back to investors in 2025 *the lowest since the 2008–09 financial crisis.* LPs need distributions. GPs need to show exits. That pressure flows directly into transaction activity, and it is a tailwind for sellers in quality businesses.

On the credit side, the direct lending market is actively borrower-friendly. U.S. direct lending dry powder hit a new record of $146 billion at end-2025. SOFR spreads compressed to record lows: 81% of deals had spreads below 550 basis points. Leverage multiples are stable at around 4.5x with room to expand 0.5–1.0x as rates come down.

The Federal Reserve held rates at 3.50%–3.75% at its January 2026 meeting, and markets are pricing two cuts by year-end, though the Iran conflict (more on that below) is pushing the expected start date further out. CPI in January 2026 was 2.4% headline and 2.5% core, both trending down before the oil shock.

The Iran conflict: déjà vu of the April 2025 tariff shock.

On March 1, 2026, U.S. and Israeli strikes on Iran effectively closed the Strait of Hormuz. Brent crude surged toward $77–82/barrel. The Dow dropped more than 1,000 points on March 3. The 10-year Treasury yield climbed above 4.06% as inflation fears resurfaced. Oxford Economics estimates a base-case conflict duration of 1-3 weeks, but warns that a sustained disruption could add 0.6–0.7% to global inflation and materially delay Fed cuts.

For the LMM specifically, this mirrors what happened in April 2025 when tariff uncertainty caused deal volume to drop roughly 40% quarter-over-quarter. Expect near-term deal pauses, widening bid-ask spreads on businesses with energy or import cost exposure, and lenders tightening underwriting standards on margin-sensitive sectors. Buyers who can move decisively during the uncertainty tend to find the best deals, but execution discipline matters more than ever.

SBA lending is contracting, and the policy changes are only just beginning.

SBA 7(a) originations through the first five months of FY2026 totaled $11.78 billion , an 18% decline from the same period the prior year. The policy changes driving this are significant: a new citizenship-only eligibility requirement (effective March 2026) eliminates green card holders from qualification, reversing the recent "Do What You Do" underwriting expansion, and changes to SBSS credit scoring that tighten approval thresholds.

The IBBA's Q4 2025 Market Pulse found that 41% of business brokers have experienced transaction delays directly attributable to these new SBA policies. Current 7(a) variable rates run approximately 10%–13.5% (prime of 6.75% plus allowable spread). For buyers who relied on SBA financing as their primary acquisition vehicle, these changes require a serious rethink of capital structure: seller notes, earnouts, and mezzanine debt are becoming more central to LMM deal structures, with earnouts now appearing in roughly 22% of all transactions.

The boomer succession wave is not slowing down.

Whatever short-term macro noise exists, the structural supply story for the LMM is as strong as it has ever been. McKinsey projects 6 million small and mid-size businesses will face ownership transitions by 2035, representing $5 trillion in enterprise value. 10,000 baby boomers are turning 65 every day. Most of their businesses are in the exact $1M–$25M EBITDA range that defines the lower middle market.

The IBBA data confirms this is already flowing into broker pipelines. Axial's Q4 2025 SMB M&A Pipeline report showed deal supply up for the fifth consecutive quarter. The problem is not finding deals. The problem is finding the right deals fast enough, in the right sectors, at prices that pencil out.

How OutSearched fits in

The single biggest challenge buyers report in the LMM is not capital, it is deal sourcing. The market is fragmented, the best deals are off-market, and proprietary flow requires relationships built over years. That is precisely the problem OutSearched was built to solve.

OutSearched is the most comprehensive M&A dealflow provider in the lower middle market, connecting buyers: private equity firms, search funds, independent sponsors, and strategic acquirers, with quality off-market and lightly marketed businesses across every sector. In an environment where record deal supply meets compressed valuations, tighter SBA lending, and geopolitical uncertainty, the competitive advantage goes to buyers who can see more opportunities, move faster, and close with conviction. That starts with better dealflow.

The market is moving. The question is whether you are positioned to move with it.
