Lower middle market M&A activity is sending mixed messages in 2026. Business owners remain interested in understanding their options, but fewer are ultimately choosing to go to market or sell, and fewer transactions are making it across the finish line.
Calder Capital is seeing this firsthand. Through Q3, our Sell-Side information requests are up approximately 7% and valuation deliverables are up 12%, while signed Sell-Side engagements are down 24%. Broader market data points in a similar direction. BizBuySell and KeyBanc have reported declining transaction activity, while Axial’s First Half 2026 survey found a significant increase in advisors citing valuation expectations as the primary reason deals fail to close.
Calder’s Buy-Side activity provides another perspective on the market through Q3. The team generated 2,750 introductions to off-market sellers, held 1,175 meetings and owner conversations, submitted 213 offers, and closed 21 acquisitions through September. Sourcing opportunities is only part of completing an acquisition: buyers also need to understand seller priorities, explore deal structures that can bridge valuation gaps, and establish financing capacity early. Together, Calder’s Buy-Side and Sell-Side observations point to a market where activity continues, but aligning expectations and executing carefully remain central to closing.

In Calder Capital’s Q3 2026 Lower Middle Market M&A Update, Founder and Managing Partner Max Friar examines what may be contributing to the disconnect between owner interest and completed transactions, including a rapidly emerging factor: artificial intelligence use. As sellers, buyers, lenders, and advisors increasingly use AI to analyze valuations, diligence materials, and transaction risks, these tools are beginning to influence expectations and negotiations throughout the M&A process.
Key Takeaways
- Owner interest is rising, but fewer are moving forward with a sale. Calder’s information requests are up 7% and valuation deliverables are up 12% this year, while signed Sell-Side engagements are down 24%, matching trends identified through Axial and other M&A industry reports.
- Valuation expectations are becoming a bigger obstacle to closing deals. In Axial’s First Half 2026 survey, Max cites that 57% of advisors identified valuation expectations as the leading reason deals failed to close, compared with 28% in 2025.
- AI can inform valuation discussions, but its conclusions need to be pressure-tested. Prompts, assumptions, and underlying sources can significantly influence the answer. Owners should test AI-generated valuations from the buyer’s and lender’s perspectives as well.
- Buyers are using AI to scrutinize deals more closely. AI makes it easier to analyze contracts, challenge add-backs, build diligence requests, and identify potential risks. Sellers should be prepared to support their financial adjustments and other key information throughout diligence.
- A valuation gap may involve more than the total purchase price. Cash at closing, financing, working capital, seller notes, earnouts, and rollover equity can all influence the economics of a transaction and whether the parties ultimately reach an agreement.
