Lower-middle-market sale processes now run 14 weeks to signed LOI

New Yanne Capital research says lower-middle-market M&A sale processes now take a median 14 weeks from banker engagement to signed letter of intent, up from 2022, as buyer-list quality and deeper diligence slow deals. The findings suggest founders need cleaner data rooms, better buyer segmentation and more time for strategics.

Why it matters: - Lower-middle-market sellers are spending more time in market before reaching a signed LOI, which can delay outcomes and increase the risk of process fatigue. - Buyer response rates have fallen sharply, and LOI-to-close dynamics are weaker, making process design more important for founders and bankers. - Strategic buyers can still command a premium, but only if the process is structured to match how those buyers actually approve deals.

What happened: - Yanne Capital said the median lower-middle-market sale-side process now takes 14 weeks from banker engagement to signed LOI. - The firm's research compares that pace with the 12-week timeline commonly used in pitch decks and with the 2022 pace, when the process was four weeks faster. - Yanne Capital published an operator's map that breaks the sale process into week-by-week stages and shows where delays now occur. - The research was released in New York on September 16, 2026.

The details: - Weeks 1-2 still cover CIM preparation and buyer-list construction. - Weeks 3-4 remain the first outreach wave. - Weeks 5-6 cover management meetings and IOIs. - Weeks 7-8 are for LOI selection. - Weeks 9-12 are for confirmatory diligence and signing. - Buyer-list construction now takes two weeks instead of one because sponsor coverage needs more curation. - Diligence now stretches longer because sponsors are doing deeper commercial diligence and quality-of-earnings work before funding an LOI. - A generic 80-name sponsor blast produces a 38% response rate in the current market, down from 61% in 2022. - A curated 25-name list built for sector fit and check-size fit can produce response rates above 70%. - Yanne Capital said PE sponsors with committed capital in the relevant size band make up about 60% of the addressable buyer set in this market. - Strategic corporate development makes up the other 40%, and its share has grown as public strategics look for growth through acquisition. - Mixing sponsors and strategics in one outreach wave is a common mistake in founder-run processes. - The biggest change in recent years is the drop in IOI-to-LOI conversion. - In 2022, about two-thirds of IOIs converted to signed LOIs. - That figure is now closer to 41%, based on transactions tracked through Mergermarket and Yanne Capital's process observation. - The lower conversion rate means a founder needs about 60% more IOIs to reach the same closing probability. - Buyers are scrutinizing customer concentration, gross retention curves and financial adjustments earlier in the process. - Yanne Capital said the paper details ten diligence questions that drive conversion in the current market. - Roughly one in four signed LOIs in the lower middle market now fail to reach close, based on S&P Capital IQ transaction data and the firm's process experience. - Most failures stem from confirmatory diligence uncovering issues not fully disclosed at the CIM stage, including customer notices, founder-key-person concentration in bookings or working-capital swings. - Yanne Capital argues the confirmatory diligence package should be treated as the real deliverable of weeks 1-2, not the CIM. - The firm says surfacing material issues in the data room on day one can shorten weeks 9-12 by two to three weeks and reduce retrades. - Strategic corporate development, which was quieter in 2023 and early 2024, is active again in lower-middle-market deals. - Yanne Capital said strategic-led processes follow quarterly board-approval cycles, not banker timelines, and can take 16-18 weeks when included in a 12-week process. - The paper recommends dual-track processes when the buyer set includes both sponsors and strategics. - In that model, sponsors stay on a standard 12-week clock while strategics run on a parallel 16-week clock with aligned milestone gates. - Yanne Capital said that approach can preserve the strategic premium, typically 15% to 25% above sponsor bids, while keeping sponsor optionality. - The company included a LinkedIn link in the release: Yanne Capital on LinkedIn.

Between the lines: - The research points to a shift from valuation-first thinking to process-quality thinking. - Better buyer targeting and earlier diligence disclosure now matter as much as headline price in getting a deal to close. - The rise of strategic buyers adds upside, but it also complicates timeline management because strategics move on internal approval cycles.

What's next: - Founders and advisors are likely to spend more time building curated buyer lists before launch. - More processes may move to dual-track structures when sponsor and strategic buyers are both in play. - Sellers that pre-package diligence issues early may have a better chance of closing at the original LOI price.

The bottom line: - Lower-middle-market sales are taking longer, converting less reliably and demanding more upfront discipline from sellers who want to keep leverage through signing and close.
