2026 Lower Middle Market M&A Outlook: Valuations, Deal Activity & Market Trends

The lower middle market is entering 2026 with a familiar mix of cautious optimism and hard-earned discipline.

Following a somewhat choppy 2025 shaped by macro volatility, shifting financing conditions, and persistent valuation gaps, dealmakers are beginning to see signs of stabilization. Capital remains active, advisors expect to win more engagements, and buyer interest in high-quality assets is holding firm—though alignment between buyers and sellers continues to determine whether deals ultimately get done.

This report draws on insights from a recent Axial member survey of 107 lower middle market participants across both the buy- and sell-side. It also incorporates comparisons to Axial’s mid-year 2025 sentiment survey, highlighting how perspectives on deal activity, valuations, and market dynamics have evolved over the past 6-9 months.

Together, the data and commentary offer a snapshot of what’s changing, what’s holding steady, and what it will take for improved sentiment to translate into completed transactions in 2026.

Why Deals Failed to Close in 2025

What is the single biggest reason deals failed to close in 2025?

The leading cause of deal failures in 2025 was valuation expectations, cited by 28.3% of respondents, narrowly ahead of diligence findings (24.5%). Macroeconomic uncertainty (20.8%) and financing constraints (17.9%) also played significant roles, underscoring external pressures and challenges with capital availability. These factors appear throughout the survey and are further explored in the sections that follow.

Investor Perspectives: Capital, Competition & Constraints

Deal Closing Expectations

Compared to 2025, how difficult do you expect it will be to close M&A transactions in 2026?

Investor sentiment suggests a more stable deal environment heading into 2026. Half of respondents expect closing conditions to remain about the same as in 2025, while 32.1% anticipate an easier path to getting deals done. Just 17.9% expect conditions to worsen.

This marks a clear shift from mid-2025 sentiment, when 56.2% of investors reported that getting deals done had become harder, and just 6.2% experienced an easier environment.

Anticipated Constraints on Investment Activity in 2026

What do you anticipate the top constraint on deploying capital will be?

Limited quality deal flow continues to be the top constraint on deploying capital, cited by 37.9% of investors in 2026, though notably down from 56.3% in 2025.

At the same time, other challenges are becoming more pronounced. Concerns around operational risk (20.7%, up from 12.5%) and macroeconomic factors (13.8%, up from 6.3%) have increased, suggesting investors are shifting focus from simply finding deals to underwriting them more carefully. Valuations remain a consistent consideration, while financing constraints appear relatively stable.

Evolving Investor Flexibility on Valuation

How willing are you to stretch on valuation for a high-quality asset?

Compared to mid-2025, investors appear slightly more measured in their willingness to stretch on valuation. The share of respondents who are very willing to pay up for a high-quality asset dropped to 11.1% (from 25.0%), while those somewhat willing increased to 37.0% (from 25.0%).

At the same time, reluctance has risen. 25.9% of buyers are now somewhat reluctant (up from 12.5%), signaling a shift toward more disciplined underwriting, even for high-quality opportunities.

Advisor Insights: Seller Behavior & Deal Execution

Engagement Activity Expected to Increase

Do you expect to win more or fewer client engagements in 2026 compared to 2025?

M&A advisors are broadly optimistic about engagement activity in 2026. 77.9% expect to win more client engagements than in 2025, while just 3.9% anticipate fewer, and 18.2% expect activity to remain about the same.

Compared to mid-2025, when 57.9% of advisors expected engagement levels to remain flat and none anticipated a decline, sentiment now points to an increase in sell-side activity.

Seller Sentiment Remains Cautious and Engaged

How would you describe seller sentiment right now?

Seller sentiment continues to be “opportunistic, but cautious,” cited by 61.5% of advisors in 2026, roughly in line with 63.2% in mid-2025. Notably, fewer sellers are pausing processes (6.4% vs. 15.8% in mid-2025), while the share of eager sellers has increased to 19.2% (from 10.5%).

2025 Deal Closing Rate

What percentage of deals with a target close date in 2025 ultimately closed?

Looking back on 2025, 58.6% of advisors reported that more than half of their deals closed, including 27.2% who closed over 75% of processes. At the same time, 41.4% reported closing half or fewer of their deals, highlighting the continued execution challenges across the market.

More Deals Are on Hold—Not Dead

Of the deals that didn’t close as intended, did more die or go on hold?

Among deals that didn’t close as intended, advisors report that more are going on hold than dying outright. Nearly half (48.7%) indicated more deals were paused, compared to just 13.2% that saw more deals fall apart, while 38.1% reported no meaningful difference between the two.

Below, advisors share additional context on what’s driving these outcomes, with common themes including macroeconomic uncertainty, valuation misalignment, and seller readiness challenges. Many noted that deals are being paused due to financial preparedness issues or shifting expectations, rather than a lack of buyer interest, while others pointed to financing dynamics and external market conditions as contributing factors.

2026 M&A Outlook: Dealmaker Perspectives & Market Dynamics

Cautious Optimism for a Stronger 2026 M&A Environment

How confident are you that 2026 will be a stronger year for lower middle market M&A than 2025?

Dealmakers are largely optimistic that 2026 will outperform 2025, with 70.5% expressing confidence—including 25.7% who are very confident and 44.8% somewhat confident. Meanwhile, 19.1% remain neutral or uncertain, and just 10.5% express doubt.

The data reflects a market leaning positive, though not without reservations. Below are select quotes from the surveyed dealmakers that provide additional context for their confidence level for 2026.

Taken together, dealmaker commentary points to a market supported by strong tailwinds—including ample capital availability, improving financing conditions, and a growing supply of motivated sellers—but still constrained by valuation alignment and macro uncertainty.

As Vlad Ilyusha of Light3 Capital Group puts it, “All the ingredients are there: record dry powder that’s aging out, financing conditions improving, and a huge wave of boomer-owned businesses that can’t wait forever. The back half of 2025 already felt like a gear shift, with buyer engagement picking up and processes moving faster. The question is whether buyers and sellers can get aligned on value.”

While confidence in 2026 is building, many dealmakers emphasized that pricing expectations and overall alignment between buyers and sellers will be key to translating improved sentiment into completed transactions.

Valuation Expectations for 2026

What is your expectation for valuation multiples in 2026 relative to 2025?

Most dealmakers expect valuation multiples to hold steady in 2026. A clear majority (61.9%) anticipate valuations will remain stable relative to 2025, while sentiment on directional movement is mixed—18.1% expect slight increases, and 18.1% expect slight decreases. Very few respondents expect more dramatic shifts in either direction.

The table below features commentary from a selection of respondents on what they believe will drive valuation trends in 2026.

Dealmaker commentary reinforces the expectation of relative stability in valuation multiples, though the underlying drivers vary. Some point to increased buyer competition and improving financing conditions as supportive of pricing, while others highlight macroeconomic uncertainty, potential increases in deal supply, and evolving buyer selectivity as moderating forces.

To better understand how these dynamics are evolving, we asked dealmakers to identify the factors exerting the greatest upward and downward pressure on valuations today—and how those forces compare to mid-2025.

Competing Forces Shaping Valuations

Which factor is having the greatest upward pressure on valuations right now?

Which factor is having the greatest downward pressure on valuations right now?

Surveyed Axial dealmakers point to strong buyer competition for quality assets as the primary driver of upward valuation pressure (46.7% in 2026, up from 42.9% in 2025). Meanwhile, macroeconomic uncertainty was again the most commonly cited factor applying downward pressure (39.4% vs. 42.4% in 2025), followed by business performance (31.7%, up from 24.2%). The responses suggest a market balancing optimism around high-quality opportunities with caution tied to external volatility and business performance.

Buyer Competition Outlook: Stable or More Competitive

Compared to 2025, how much investor competition do you expect in deal processes in 2026?

A majority (52.4%) expect investor competition to remain about the same as in 2025, while a meaningful 37.1% anticipate a more competitive landscape, and just 8.6% expect less competition. This suggests that while competition may not intensify materially across the board, a meaningful portion of the market is preparing for increased investor interest.

Trends to Watch in 2026

Looking ahead, surveyed Axial dealmakers are closely monitoring a mix of technological disruption, shifting capital dynamics, and evolving seller behavior. Themes such as the rise of AI, increased deal supply from aging business owners, and new sources of buyer capital are expected to shape activity, while interest rates, sector-specific tailwinds, and operational efficiency gains could influence both deal flow and valuations.

Below, dealmakers share the trends they’re watching most closely as 2026 unfolds.

Final Thoughts

Across the data and dealmaker commentary, a consistent picture emerges: capital is ready, sellers are increasingly motivated, and activity is picking up. But execution will continue to depend on discipline, particularly around valuation expectations, underwriting rigor, and navigating macro uncertainty.

Those who can bridge the gap between opportunity and alignment may be well positioned to benefit from a more active—and potentially more productive—2026.
