Buyout tiers · Updated 2026
Middle Market Private Equity Firms: How the Mid-Cap Tier Actually Works
Middle market private equity firms acquire companies with roughly $50M–$500M in enterprise value and $10M–$50M of EBITDA — one tier above the lower middle market and below large-cap buyout. Deals in this band typically use 40%–55% equity, a 4–6 year hold, 10%–30% founder rollover, and value creation driven by add-on acquisitions and commercial execution rather than by professionalizing basic finance and operations.

Coyote Wealth data point
3.4 add-ons
Median add-on acquisitions per middle-market platform before exit (Coyote Wealth 2026 editorial estimate)
Derived from Coyote Wealth's review of disclosed platform histories across 60 middle-market portfolio companies exited between January 2023 and June 2026, supplemented by practitioner interviews. Lower middle market platforms in the same sample averaged 1.6 add-ons; upper middle market platforms averaged 4.9. This is an editorial estimate from public disclosures, not audited data.
15 active middle market private equity firms
Audax Private Equity
Focus: 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
Focus: 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
Focus: 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
Focus: 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
Focus: 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
Focus: 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
Focus: 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
Focus: 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
Focus: 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
Focus: 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
Focus: 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
Focus: 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
Focus: 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
Focus: 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
Focus: 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.
Also active in the core middle market: Berkshire Partners, ABRY Partners, HIG Capital (multiple strategies), Wynnchurch Capital, Kelso & Company, One Equity Partners, and dozens of sector specialists. Inclusion is editorial, is not an endorsement, and is not a solicitation. No firm paid for inclusion.
What 'middle market' means as a distinct tier
The private equity market is segmented by enterprise value, not by ambition. Coyote Wealth uses $50M–$500M of enterprise value as the core middle market band, with $10M–$50M of EBITDA as the operating proxy. Below that sits the lower middle market ($5M–$100M EV, $2M–$10M EBITDA), where owner-dependency is the dominant risk. Above it sits the upper middle market ($500M–$1B) and then large-cap buyout, where deals are syndicated, banked, and priced against public comparables.
The tier boundaries are not cosmetic. They determine which lenders will underwrite the capital structure, how many bidders show up, whether a sell-side bank runs a broad auction or a targeted process, and — most consequentially for a seller — whether the buyer's return model depends on fixing the company or on growing it.
A useful test: if the buyer's investment committee memo spends most of its pages on management succession and systems, you are in the lower middle market. If it spends most of its pages on the add-on pipeline and pricing strategy, you are in the middle market.
How middle market funds structure deals differently
Capital structure
Typically 40%–55% equity with the balance in unitranche or club bank debt. Since 2023, private credit rather than syndicated bank debt has financed most of this band, which means one lender relationship instead of an arranged syndicate and faster, more certain closes at a higher coupon.
Rollover and management equity
Founder rollover of 10%–30% is standard, and the option pool for the broader management team is usually 8%–12% of fully diluted equity with a mix of time and performance vesting. In the lower middle market the pool is often smaller and less formalized.
Governance
A real board with independent directors, quarterly reporting packages, and a defined 100-day plan. Middle-market sponsors generally install a controller-to-CFO upgrade path and a monthly close discipline within the first two quarters.
Value creation model
Add-on M&A is the primary lever. Coyote Wealth's estimate of 3.4 add-ons per platform reflects a market where multiple arbitrage — buying $4M-EBITDA businesses into a $25M-EBITDA platform — is more reliable than organic growth alone.
Hold period and exit path
Four to six years, with exits split between upper-middle-market sponsors, strategics, and continuation vehicles. Continuation funds have become a genuine third exit route in this band rather than an exception.
Process shape
Broad two-round auctions run by core middle-market banks, 80–150 buyers contacted, indications of interest at week 6–8, and 60–90 days of confirmatory diligence. Expect quality-of-earnings, IT, insurance, and often ESG workstreams that a lower-middle-market process would skip.
Where middle market PE goes wrong for sellers
The most common seller mistake in this band is comparing headline enterprise values across bids with different structures. A structured-equity bid with a contractual coupon, an all-cash control bid with a small rollover, and a bid with a large rollover into a buy-and-build platform can produce wildly different outcomes at the same nominal price.
The second is treating add-on strategy as the buyer's problem. If the thesis depends on acquiring four competitors and you know two of them will never sell, the plan that justifies the multiple is already impaired — and you may be holding rollover equity in it.

Frequently asked questions
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.
