Coyote Wealth data point
3.4 add-ons
Median add-on acquisitions per middle-market platform before exit (Coyote Wealth 2026 editorial estimate)
From Coyote Wealth's review of disclosed platform histories across 60 middle-market portfolio companies exited between January 2023 and June 2026. Add-on cadence is the single clearest observable difference between the middle market and the tier below it, where the same sample averaged 1.6 add-ons per platform.
The 2026 Criterion ranking
Audax Private Equity
Coyote Composite 4.72/5Focus: Buy-and-build across industrials, healthcare, software, and services
HQ: Boston, MA
- Typical EV:
- $100M–$500M
- Platform EBITDA:
- $10M–$50M
- Style:
- Programmatic add-ons
Audax runs one of the most systematic add-on programs in the middle market, with a dedicated origination team that sources bolt-ons for platforms rather than leaving it to management. Best fit for founders who want the business to become a consolidator rather than be consolidated.
Watch-out: A high add-on cadence means integration work starts early. Management teams that want a quiet three years post-close are usually a poor fit.
Genstar Capital
Coyote Composite 4.68/5Focus: Financial services, software, healthcare, industrials
HQ: San Francisco, CA
- Typical EV:
- $200M–$1B+
- Style:
- Thesis-led, sector-repeat
Genstar re-underwrites the same sub-sectors repeatedly, which shows up as unusually specific diligence questions and a strategic advisory board with genuine operating history in the vertical. Sits at the upper end of the middle market and often crosses into upper-middle-market pricing.
Watch-out: Below roughly $150M of enterprise value the fund is generally out of band.
Sentinel Capital Partners
Coyote Composite 4.61/5Focus: Franchising, food, business services, aerospace/defense, consumer
HQ: New York, NY
- Typical EV:
- $75M–$400M
- Platform EBITDA:
- $10M–$60M
One of the few middle-market funds with real franchising and multi-unit expertise, which is a genuinely different underwriting discipline from generalist industrials. Comfortable with founder- and family-owned sellers.
The Riverside Company
Coyote Composite 4.57/5Focus: Multi-strategy across LMM and core middle market, global
HQ: New York, NY
- Typical EV:
- $50M–$400M
- Style:
- Fund family by size band
Riverside runs separate vehicles by size, so a $60M business and a $350M business are underwritten by different teams with different return math. Useful when a seller wants a buyer that will still be the right owner after the company doubles.
Watch-out: Ask which specific fund is bidding — the experience of working with Riverside varies meaningfully across strategies.
Court Square Capital Partners
Coyote Composite 4.52/5Focus: Business services, healthcare, industrials, technology/telecom
HQ: New York, NY
- Typical EV:
- $150M–$750M
Long-tenured team with a Citicorp Venture Capital lineage and a preference for control buyouts of established, cash-generative businesses. Sits at the boundary between core and upper middle market.
Charlesbank Capital Partners
Coyote Composite 4.48/5Focus: Business services, industrials, consumer, technology infrastructure
HQ: Boston, MA
- Typical EV:
- $150M–$750M
Flexible mandate that includes both control buyouts and structured/opportunistic credit, so the firm can propose a non-control solution when a full sale is not what the owner wants.
Gryphon Investors
Coyote Composite 4.44/5Focus: Healthcare, business services, consumer, software, industrial growth
HQ: San Francisco, CA
- Typical EV:
- $100M–$600M
- Style:
- Operator-partner model
Deal teams are paired with dedicated operating partners from the first meeting rather than after close, which tends to make the 100-day plan concrete during diligence instead of aspirational.
Nautic Partners
Coyote Composite 4.39/5Focus: Healthcare, industrials, outsourced services
HQ: Providence, RI
- Typical EV:
- $100M–$500M
Three-sector discipline maintained across decades, with a strong healthcare-services franchise. Sector concentration means references from prior portfolio CEOs are unusually relevant to your own situation.
Kohlberg & Company
Coyote Composite 4.34/5Focus: Healthcare, industrials, business and consumer services
HQ: Mount Kisco, NY
- Typical EV:
- $200M–$1B
Runs both a core middle-market fund and a smaller-cap vehicle, giving it a wide addressable band. Heavy emphasis on structured operational improvement plans.
Watch-out: Underwriting is institutional and process-heavy; founder-led sellers should budget for a longer diligence period.
Levine Leichtman Capital Partners
Coyote Composite 4.29/5Focus: Structured equity in franchising, education, business services
HQ: Los Angeles, CA
- Typical EV:
- $50M–$400M
- Style:
- Structured (debt + equity)
Uses a structured capital approach that can let an owner retain a larger equity stake than a straight control buyout allows. The trade is a contractual return on the debt component regardless of the equity outcome.
Watch-out: Model the coupon before comparing headline valuations against pure-equity bids — the two are not directly comparable.
Alpine Investors
Coyote Composite 4.25/5Focus: Software and services, CEO-led buy-and-build
HQ: San Francisco, CA
- Typical EV:
- $50M–$400M
- Style:
- People-first / CEO placement
Distinctive model built around installing trained operators as CEOs, which is a real answer to the most common middle-market failure mode: a founder who leaves and no bench behind them.
Watch-out: If the incumbent management team expects to remain in place indefinitely, confirm intentions early.
Shore Capital Partners
Coyote Composite 4.20/5Focus: Healthcare, food and beverage, business services microcap-to-middle-market roll-ups
HQ: Chicago, IL
- Typical EV:
- $25M–$300M (platform + add-ons)
- Style:
- Founder-partnership roll-ups
Enters below the middle market and builds into it, which makes Shore relevant to owners who want a middle-market outcome without already being a middle-market company.
Sverica International
Coyote Composite 4.14/5Focus: Healthcare, industrial technology, business services
HQ: Boston, MA
- Typical EV:
- $50M–$250M
Sits at the LMM/middle-market boundary with a growth-oriented rather than leverage-oriented approach, and a stated preference for businesses with modest existing debt.
Incline Equity Partners
Coyote Composite 4.09/5Focus: Value-added distribution, specialty manufacturing, business services
HQ: Pittsburgh, PA
- Typical EV:
- $50M–$350M
Deep distribution expertise, a sector many generalists underwrite poorly because working-capital dynamics dominate the return model.
Ridgemont Equity Partners
Coyote Composite 4.03/5Focus: Business and industrial services, healthcare, energy services, telecom
HQ: Charlotte, NC
- Typical EV:
- $50M–$350M
Bank-spinout heritage with a Southeast footprint and a willingness to take minority growth positions alongside control buyouts.
Firms considered but not scored this cycle because disclosed activity fell largely outside the $50M–$500M band: Berkshire Partners, Kelso & Company, ABRY Partners, and Wynnchurch Capital. No firm paid for inclusion or placement, and no firm was contacted for approval of its entry.
How the Coyote Composite is built
The Coyote Composite is a 0–5 editorial score built from four weighted factors specific to the middle market. Deal-size fit carries 30%: how consistently the firm actually transacts inside the $50M–$500M enterprise-value band, rather than marketing into it while deploying above or below. Sector focus depth carries 25%, measured by repeat transactions in the same sub-sector and the presence of sector-specific senior hires.
Operational value-add carries 25%, assessed from the structure of the firm's operating resources — dedicated operating partners, an in-house add-on origination function, and disclosed executive-placement capability — rather than from marketing claims. Fund vintage and track record carries the final 20%, reflecting fund count, team continuity across at least one full cycle, and disclosed realizations.
The composite is not a performance rating, does not incorporate net IRR or DPI, and does not predict returns. It is an editorial view of fit and capability for a middle-market owner choosing among bidders.
How to use this ranking
Rank order is not a shortlist. A $70M-enterprise-value business is usually better served by Sverica, Incline, or Shore than by a firm at the top of the list whose deal teams are staffed for $300M transactions, even though those firms score higher on absolute capability.
Start with the size band in each entry, filter to the two or three firms whose sector history matches your business, and then use the scorecard in our companion guide to compare structures rather than headline prices.

- Objective — deal-size fit (30%): share of disclosed control transactions over the trailing 24 months falling inside the $50M–$500M enterprise-value band.
- Objective — sector focus depth (25%): count of repeat transactions within the same sub-sector and presence of named sector-dedicated senior professionals.
- Objective — fund vintage and track record (20%): number of institutional funds raised, senior-team continuity through at least one full cycle, and disclosed realizations.
- Subjective — operational value-add (25%): structure and depth of operating resources, add-on origination capability, and counterparty-reported conduct during diligence and post-close.
- Inputs are drawn from firm disclosures, press-released transactions, SEC filings where applicable, and practitioner interviews conducted between October 2025 and June 2026.
- Scores are editorial estimates on a 0–5 scale. They are not performance ratings, do not incorporate fund returns, and do not predict future results. Quoted views are paraphrased from interviews and are not attributed statements by the firms listed.
- Limitations: middle-market deal terms are largely undisclosed, so activity data understates firms with private-company clientele and no press-release practice. A single scoring cycle cannot distinguish a strong year from a strong franchise.

Frequently asked questions
How does Coyote Wealth rank middle market private equity firms?
Each firm receives a 0–5 Coyote Composite score weighting deal-size fit (30%), sector focus depth (25%), operational value-add (25%), and fund vintage and track record (20%). Inputs come from disclosed transactions, firm and regulatory filings, and practitioner interviews. Scores are editorial estimates, not performance ratings.
Are these rankings based on fund returns?
No. Net IRR, TVPI, and DPI are not inputs. Middle-market fund performance is disclosed inconsistently and largely to limited partners, so a returns-based ranking would be unreliable. The composite measures fit and capability for an owner or management team choosing among bidders.
What is a middle market private equity firm?
A middle market private equity firm buys control or significant minority stakes in companies with roughly $50M–$500M in enterprise value, typically $10M–$50M of EBITDA. It sits one tier above the lower middle market (sub-$100M EV, $2M–$10M EBITDA) and below the large-cap buyout funds that write billion-dollar checks.
What deal size counts as middle market private equity?
Coyote Wealth defines the core middle market as $50M–$500M of enterprise value. Practitioners often split it further: lower middle market below $100M, core middle market $100M–$500M, and upper middle market $500M–$1B. Definitions vary by firm, so always confirm the band a fund is actually deploying into rather than the band it markets.
How is middle market PE different from lower middle market PE?
Middle-market targets usually have an established finance function, audited or reviewed statements, a management team below the founder, and a real second layer of customers. That changes the deal: less owner-dependency risk, more leverage available, more competitive auctions, higher entry multiples, and value creation driven by M&A and commercial execution rather than by professionalizing the basics.
What multiples do middle market PE firms pay?
Entry multiples in the core middle market generally run several turns above the lower middle market for comparable businesses, because auctions are broader and more debt is available. Coyote Wealth's editorial estimate for 2026 is a mid-single-digit to low-double-digit EBITDA range depending on sector, growth, and customer concentration, with software and healthcare services at the top of the range and cyclical industrials at the bottom.
How much equity do middle market funds put into a deal?
Equity contributions of roughly 40%–55% of total capitalization have been the norm since rates repriced in 2023. Lower leverage means returns depend more on EBITDA growth and multiple expansion through add-ons than on debt paydown.
Does a middle market PE firm let the founder keep equity?
Frequently. Rollover equity of 10%–30% is common in control buyouts, and structured-equity firms can leave an owner with more. Rollover is the single largest driver of a founder's total economics across a two-transaction path, so it deserves as much negotiation attention as the headline price.
