Private Equity Capital Stack: The 2026 LMM Operator’s Guide

The private equity capital stack is the ordered set of debt and equity instruments a sponsor layers on top of your company to fund a buyout, recapitalization, or growth round, ranked by seniority in repayment. For a lower middle market business generating $1M to $25M of EBITDA, the stack usually blends senior secured debt, sometimes a unitranche or mezzanine layer, preferred equity from the sponsor, and rollover common equity from the management team. Each layer carries its own coupon, dilution cost, control right, and downside protection, and the mix you accept sets your economics for the next five to seven years.

This guide is written for the operator on the sell-side of that conversation, the owner or founder deciding what to accept, not the sponsor pitching the deal. If you are running a $3M to $50M revenue company, thinking about a partial sale, a full exit with rollover, or a growth recap that funds a build-out and takes chips off the table, the sections below give you the layer-by-layer math, named sponsor benchmarks from 2024 through 2026, and the process a lower middle market advisor would run to source competing term sheets.

In our experience advising LMM operators raising private equity capital stack layers, the single biggest value leak is accepting the first term sheet without running a real process. Owners who sign a proprietary LOI in week two usually give up one to two turns of EBITDA against what a competitively marketed process would have surfaced. The second value leak is misreading preferred equity as cheap. A 12% PIK preferred with a 2.0x minimum multiple compounds into real dollars that come off the common waterfall before you see a nickel. Structure math on day one saves you from surprise math on day 1,825.

What is the private equity capital stack, in plain English?

The private equity capital stack is the ordered layering of debt and equity a sponsor uses to fund a buyout or recap, senior secured at the bottom, common equity at the top, with unitranche, mezzanine, and preferred equity in between. Each layer has its own price, its own control rights, and its own place in the payment waterfall. GF Data has reported blended lower middle market leverage of roughly 4.0x EBITDA across its quarterly sample, split across two to four instruments.

Picture the stack as a stack of pancakes. The bottom pancake, senior secured debt, gets paid first every quarter and gets paid first in a liquidation. The top pancake, common equity, gets paid last but captures all upside above the debt principal and the preferred hurdles. The middle pancakes, mezzanine and preferred, are the flexible layers a sponsor uses to fill the gap between what a bank will lend and what the sponsor is willing to write as an equity check.

The math matters because every layer has a cost of capital, and the blended cost of the stack determines what internal rate of return the sponsor needs to hit at exit. A stack that runs 4.0x turns of leverage at 8% blended debt cost plus 3.5x turns of equity at a 25% target IRR implies a specific set of assumptions about your growth, your EBITDA multiple at exit, and how much cash the business throws off during the hold. When any of those assumptions slip, the layer that gets squeezed first is common equity, which is usually where the founder’s rollover sits.

Who typically uses a private equity capital stack, and who does not?

Lower middle market operating businesses with $1M to $25M of EBITDA, stable cash flow, and a real management team are the sweet spot for a full private equity capital stack. Sponsors like Riverside Company, Audax Private Equity, and Kian Capital anchor thousands of platform and add-on deals a year in this band. Pre-revenue startups, unprofitable early-growth companies, and micro-businesses under $1M EBITDA typically use different capital, not a sponsor-led stack with senior debt and preferred layers.

The audience for a real capital stack is the founder or owner who has proven the business model, generated three or more years of consistent EBITDA, and either wants liquidity, wants growth capital to scale, or wants to hand day-to-day operations to a partner while retaining a second bite through rollover. If your business fits that profile, a sponsor stack is almost always a serious option to consider next to a strategic sale.

The audience that is not served by this playbook is the pre-seed or seed-stage startup founder raising a first priced round on a SAFE or a convertible note, the crowdfunded operator raising $500K on Wefunder or StartEngine, and the friends-and-family-check business that has never been rigorously audited. Those raises use different instruments, different sources, and a different vocabulary. This guide covers the operating-company path.

Growth-stage founders straddling both worlds, meaning a bootstrapped software or services business that has never taken outside capital but is now $10M in ARR, sit squarely in this guide’s audience. They usually pattern-match to a growth equity round from a firm like Summit Partners, TA Associates, or JMI Equity rather than a full leveraged buyout. The growth equity vs private equity comparison lays out the distinction in more depth.

How does a private equity capital stack compare to bank debt, SBA loans, and VC?

A private equity capital stack is broader, more expensive per layer, and more control-heavy than a bank line or an SBA 7(a) loan, and it is structurally different from venture capital. Bank debt and SBA are single-instrument, cash-pay, amortizing, and tied to your personal guarantee below certain thresholds. Venture capital is single-instrument preferred equity with milestones. A sponsor stack combines two to four instruments and a governance layer, and it usually replaces the owner’s personal guarantee with corporate covenants.

Capital source	Typical use	Cost / dilution	Control impact
Senior bank debt	Working capital, small acquisitions	SOFR + 250 to 400 bps	Covenants, no board seat
SBA 7(a) loan	Owner buyout under $5M, small platform	Prime + 2.75% to 3.00%, up to $5M	Personal guarantee required
Unitranche debt	LMM buyout, add-on funding	SOFR + 550 to 700 bps	Covenants, financial reporting
Mezzanine debt	Gap between senior and equity	11% to 13% cash + 1% to 3% PIK + warrants	Board observer typical
Preferred equity	Sponsor equity or structured minority	10% to 14% PIK + 1.5x to 2.0x MOIC	Protective provisions, sometimes board seat
Sponsor common equity	Majority buyout, LBO	Full dilution, 60% to 80% ownership typical	Board control, CEO hire/fire rights
Growth equity	Minority round for scale-up	20% to 40% dilution, 20% to 25% target IRR	Minority protections, board seat
Venture capital	Pre-profit tech, milestone rounds	Round-by-round dilution	Preferred stock with anti-dilution

The comparison that trips most LMM owners is bank debt versus unitranche. A bank line is cheaper by 200 to 300 basis points, but banks pull lines when covenants trip, and covenants trip during the exact business cycles when you need capital most. Unitranche lenders like Golub Capital or Ares Management price higher but underwrite through cycles and are structurally patient. The unitranche debt acquisition financing guide unpacks that trade in more depth.

The other confusion is VC versus growth equity versus LMM PE. VC underwrites option value on a portfolio, expects a large percentage of failures, and prices dilution accordingly. Growth equity and LMM PE underwrite proven cash flow and expect zero write-offs on a well-diligenced deal, per Bain & Company’s Global Private Equity Report historical loss rate data.

When does a private equity capital stack make sense for your business?

A private equity capital stack makes sense when your business has more than $3M of EBITDA, three or more years of audited or reviewable financials, a management team that can run without you, and either a liquidity need or a growth thesis that requires more capital than a bank line can prudently supply. Sponsors like Trivest Partners and Gemspring Capital anchor thousands of $3M to $15M EBITDA deals a year against exactly this fit profile.

The five fit criteria a sponsor screens on are EBITDA scale, EBITDA quality, growth trajectory, competitive positioning, and management depth. If you clear all five, you are financeable. If you clear three or four, you are financeable but with structural adjustments, meaning more preferred, more earnout, more rollover. If you clear two or fewer, a full sponsor stack is usually the wrong tool and you are better off with strategic buyer conversations, private credit, or continued organic growth.

Timing matters as much as fit. The best time to raise is when you do not desperately need the capital. Sponsors have long institutional memories, and a raise done from a position of strength closes at a materially better multiple than a raise done under time pressure. If your window is 12 to 24 months out, this is the moment to start preparing quality of earnings work and cleaning up related-party items. See the term sheet guide for what a well-prepped seller can push back on.

Fit also depends on what you want after close. If you want to keep your CEO chair for five to seven years and take chips off the table, you are a fit for a majority recap. If you want to hand the CEO role to a new hire and stay on the board, a full sale with rollover fits better. If you want to keep control and just fund a specific initiative, a minority growth round from a firm like Summit Partners or TA Associates is the right instrument.

How much does a private equity capital stack actually cost you?

The full cost of a private equity capital stack is the sum of interest, PIK accrual, preferred hurdles, common dilution, and transaction fees, and it usually lands between 12% and 18% weighted average cost of capital for an LMM deal. On a $60M enterprise value transaction with 40% sponsor equity, the transaction fees alone typically run $1.8M to $3.6M all-in, per PitchBook advisor fee benchmarks reported through 2025.

Cost line item	Typical range	Who receives it
Sell-side M&A advisor fee	1% to 5% of EV	M&A advisor or investment bank
Legal fees (seller)	$150K to $400K on $50M EV	M&A counsel
Legal fees (buyer)	$200K to $500K on $50M EV	Buyer’s M&A counsel
Quality of earnings	$75K to $200K	Accounting firm
Sponsor transaction fee	1% to 2% of EV	PE sponsor
Debt arrangement fee	1.5% to 3% of debt	Lender or arranger
R&W insurance premium	2.5% to 4.5% of limit	Underwriter
Environmental / insurance / IT diligence	$30K to $150K	Third-party diligence providers
Ongoing management fee (post-close)	2% of EBITDA, typical	PE sponsor

The line item most sellers underestimate is R&W insurance. On a $60M enterprise value deal with a $6M policy limit, the premium runs $150K to $270K and is usually shared 50/50 between buyer and seller per Marsh’s Transactional Risk Insurance practice reporting. That premium is often the difference between a clean escrow and a two-year holdback that ties up seller proceeds.

The line item most sellers overestimate is the advisor fee, because the advisor typically pays for themselves in incremental price. GF Data has reported meaningfully higher exit multiples for competitively marketed processes, on the order of 0.5x to 1.5x turns of EBITDA above proprietary single-buyer sales. On a $10M EBITDA business, that is $5M to $15M of additional value at close, which more than covers a 3% advisor fee.

Who provides private equity capital stack financing in 2026?

The providers span PE sponsors, growth equity firms, family offices, BDCs, mezzanine funds, and private credit shops, each occupying a different layer of the stack. Named platforms active in the LMM band include Audax Private Equity, Riverside Company, Trivest Partners, Kian Capital, Gemspring Capital, Golub Capital, Ares, and Antares. Family offices like the Pritzker Organization and Cranemere anchor patient-capital deals with longer hold horizons than institutional PE funds.

Sponsor / lender	Type	LMM focus	Typical check
Audax Private Equity	PE, buy-and-build	$5M to $75M EBITDA	$40M to $300M equity
Riverside Company	PE, LMM specialist	Up to $400M EV	$10M to $150M equity
Trivest Partners	PE, founder-friendly	$3M to $15M EBITDA	$20M to $75M equity
Kian Capital	PE, LMM buyout	$3M to $15M EBITDA	$15M to $60M equity
Gemspring Capital	PE, LMM	$5M to $40M EBITDA	$25M to $150M equity
Golub Capital	Unitranche, BDC	$5M to $200M+ EBITDA	$25M to $500M debt
Antares Capital	Unitranche, senior	$10M EBITDA and up	$50M to $500M debt
Summit Partners	Growth equity	$10M+ revenue, profitable	$50M to $500M
TA Associates	Growth equity	Scaled software, services	$50M to $500M+
Churchill Asset Management	Senior debt, junior capital	Middle market broad	$25M to $250M debt

The distinction that trips first-time raisers is PE sponsor vs family office. PE sponsors are institutional funds with fixed hold periods, usually five to seven years, driven by fund lifecycle math. Family offices deploy patient capital with 10+ year horizons, less pressure to exit, and often willingness to accept lower IRRs in exchange for stability. If you value long-term partnership over max-price, a family office may be a better fit. See the family office vs PE buyer comparison.

Growth equity firms like Summit Partners and TA Associates focus on companies that have already achieved scale and are not looking to leverage up. They typically take minority stakes, do not require the founder to step aside, and price at premium multiples for high-growth businesses. The selling to growth equity investor guide walks through what a minority round from that peer group looks like in practice.

How does the process work, step by step?

The private equity capital stack raise runs through a repeatable 10 to 12 step process that spans roughly 18 to 26 weeks from kickoff to close. Steps include quality of earnings, CIM preparation, buyer outreach, indications of interest, management presentations, LOI negotiation, exclusivity, confirmatory diligence, definitive agreement drafting, financing commitments, and closing. A CT Acquisitions-run process typically produces four to eight competitive term sheets at the IOI stage.

1. Kickoff and preparation (weeks 1 to 4). Engage the M&A advisor, sign the mandate, launch quality of earnings with a firm like RSM or CohnReznick, and start cleaning up related-party transactions and any add-back items.
2. CIM and teaser drafting (weeks 3 to 6). Prepare the confidential information memorandum and a blind teaser. The CIM runs 40 to 80 pages and includes financials, market position, growth thesis, and management bios.
3. Buyer list building (weeks 5 to 7). Curate a list of 40 to 150 strategic and financial buyers depending on process breadth. Broad auction, targeted process, or negotiated sale each have different math.
4. Outreach and NDA execution (weeks 6 to 8). Teasers go out, NDAs come back, CIMs are shared. Typical conversion is 40% to 60% NDA rate on qualified outreach.
5. Indications of interest (weeks 8 to 10). Buyers submit non-binding IOIs with valuation ranges, key assumptions, and process notes. Four to eight is a healthy IOI count.
6. Management presentations (weeks 10 to 12). Top three to five buyers travel to meet management. This is where fit gets tested beyond the numbers.
7. Letter of intent (weeks 12 to 14). Buyers submit LOIs with binding pricing subject to confirmatory diligence. Seller picks one and grants 45 to 90 days of exclusivity.
8. Confirmatory diligence (weeks 14 to 22). Financial, legal, tax, environmental, insurance, IT, and commercial diligence workstreams run in parallel. Sponsor commits debt and equity financing.
9. Definitive agreement (weeks 20 to 24). M&A counsel drafts the purchase agreement, disclosure schedules, escrow terms, R&W policy, and employment agreements for retained management.
10. Financing commitments (weeks 20 to 24). Debt commitment letters, equity commitment letters, and rollover paper get finalized concurrent with the definitive agreement.
11. Signing and closing (weeks 24 to 26). Sign, wire, deliver, and celebrate. Post-close working capital true-up follows in the 60 to 120 day window.

The two most common process failures are running too narrow and running too slow. Too narrow means going to five buyers when the right list is 30, which almost always leaves competitive tension unpriced. Too slow means letting the process drag past 22 weeks to LOI, which signals to remaining bidders that the seller has lost momentum and prices come down accordingly.

What paperwork and documentation do you need?

A private equity capital stack raise requires roughly 12 to 20 core documents plus a data room of several hundred underlying files. Core documents include the confidential information memorandum, quality of earnings report, corporate governance documents, financial statements, tax returns, customer and vendor contracts, employee agreements, IP registrations, environmental reports, and insurance policies. A well-organized data room reduces buyer diligence timelines by two to four weeks.

The specific documentation that materially moves valuation includes three years of audited or reviewed financial statements, monthly management-level P&L with customer concentration detail, a rigorous quality of earnings that walks reported EBITDA to normalized EBITDA with defensible add-backs, and top-20 customer contracts with change-of-control provisions clearly flagged. Anything missing from that core set will either delay the deal or price into the discount.

The data room platform matters less than the organization within it. DealRoom, Intralinks, Firmex, and iDeals all work. What matters is the folder taxonomy, the version control on updated documents, and the responsiveness to buyer questions submitted through the platform. A well-run seller updates the data room within 24 hours of a buyer question and closes the question in the tracker with a source citation.

Contracts with change-of-control provisions are the diligence item most likely to surface late and blow up a deal. Any customer or vendor contract that requires consent on a change of control needs to be identified before you launch, so you can plan whether to seek consent pre-signing, at signing, or post-close. Missing a material change-of-control provision on a top-five customer contract can knock 0.5x to 2.0x turns off the multiple in the LOI-to-close window.

What are the tax and legal implications of each layer?

The tax treatment of a private equity capital stack transaction depends on entity type, deal structure, and rollover mechanics. An LLC seller in an asset sale would generally get long-term capital gains on the purchase price minus tax basis, subject to hot-asset ordinary income. A C-corp seller in a stock sale gets long-term capital gains at the shareholder level. Rollover into a new entity structured under IRC Section 351 or 721 typically defers tax on the rollover portion, per longstanding IRS guidance.

Entity choice at close matters as much as entity choice at formation. Most PE sponsors form a new acquisition vehicle, usually a Delaware LLC or C-corp, and structure the transaction so target common gets contributed to Newco in exchange for Newco common. If executed under 351 or 721, the rollover is tax-deferred to the seller. The cash portion is fully taxable at the applicable rate in the year of the sale.

State tax exposure varies dramatically. A Florida or Texas seller has no state income tax on the gain. A California or New York seller can face 10%+ state marginal rates layered on the federal 20% capital gains plus 3.8% net investment income tax. QSBS treatment under IRC Section 1202 can shelter up to $10M of gain per shareholder on qualifying C-corp stock held five years, per IRS Revenue Ruling and subsequent guidance.

Legal implications track structure. Stock deals transfer all liabilities with the entity. Asset deals let the buyer pick and choose liabilities but usually cost the seller more in tax. Reps and warranties allocate risk on undisclosed liabilities. R&W insurance from Marsh, Aon, or Willis Towers Watson transfers most of that risk to an underwriter for a one-time premium, letting sellers close with minimal escrow. The American Bar Association’s private target deal points study tracks market terms across thousands of LMM deals annually.

What are the common structures and terms in a PE stack?

Common private equity capital stack structures include the majority recap, the full buyout with rollover, the minority growth investment, and the structured preferred equity round. Common terms across all four include liquidation preferences, PIK dividends, anti-dilution, drag-along and tag-along rights, board composition, protective provisions, and management incentive equity typically sized at 10% to 15% of common equity. Firms like Trivest structure heavily around founder-friendly rollover economics.

Majority recap is the most common LMM structure. Sponsor takes 60% to 80% of common, management rolls 20% to 35%, senior and unitranche debt fills the debt layer, and preferred equity from the sponsor fills the gap. Founder typically stays as CEO for two to five years, then transitions to executive chair or board seat. Second bite at exit is often larger per share than first bite, given the sponsor’s operational value-add and multiple expansion.

Minority growth round is the second most common structure and typical for high-growth software or services businesses. Sponsor takes 20% to 40% of common, no debt is added, founder retains operational control, and preferred stock with 1x non-participating liquidation preference is standard. This is the structure Summit Partners, TA Associates, and JMI have deployed in hundreds of software deals since 2020.

Structured preferred equity is a specialty structure used when a founder wants growth capital but does not want to sell common. A sponsor like Crescent Capital or Audax Private Debt writes a preferred check with a 10% to 14% PIK yield and a 1.5x to 2.0x minimum multiple, with warrants or a conversion feature at exit. This layer sits ahead of common in the waterfall but does not dilute common on day one.

What are the red flags and pitfalls to watch for?

The most common private equity capital stack red flags include over-leveraged structures that leave less than 1.5x fixed charge coverage, preferred equity with participating liquidation preferences, PIK-only preferred with no cash coupon and a high MOIC hurdle, drag-along rights that let the sponsor force a sale at any price, and management equity plans that vest only on a change of control. GF Data and PitchBook both track deal terms and flag outlier structures each quarter.

Over-leverage kills more sponsor deals than any other single factor. A stack that runs 5.5x total leverage on a $10M EBITDA business leaves roughly $1.5M of interest and mandatory amortization to service against $10M of EBITDA, before capex, taxes, and any downturn. When the business hits a rough quarter, cash flow squeezes fast, covenants trip, and the sponsor either injects rescue equity at a discount or watches the lender take the wheel.

Participating preferred is the second big pitfall. A non-participating preferred takes the greater of its liquidation preference or its converted common share. A participating preferred takes both, which means on a $100M exit with $30M of participating preferred at 1.5x MOIC, the preferred holder takes $45M off the top and then takes their common share of the remaining $55M. Founders regularly leave $5M to $15M on the table by not negotiating participation caps.

Drag-along rights without price thresholds are the third pitfall. A vanilla drag lets the sponsor force a sale to any buyer at any price, and the founder is contractually obligated to sign. A negotiated drag includes a minimum price threshold, a minimum sponsor IRR threshold, or a founder consent right below a specified valuation. The term sheet guide walks through the standard negotiation points.

What are the 2024 to 2026 market dynamics you need to know?

The 2024 to 2026 private equity capital stack market is defined by three forces: a $1.2 trillion global dry powder overhang, an interest rate environment that peaked in mid-2023 and is normalizing in 2026, and record volumes of continuation vehicles as sponsors extend hold periods on stuck assets. PitchBook reported roughly $1.2 trillion of North American PE dry powder at year-end 2024, per its 2024 US PE Breakdown. Ares closed a $34B direct lending fund in 2024, the largest ever.

Dry powder pressure means sponsors are under LP pressure to deploy, which typically supports LMM multiples in the 6.5x to 8.5x band for platform deals with $5M+ EBITDA. It also means add-on activity is running high, since add-ons let sponsors deploy capital at blended multiples below what a new platform commands. Bain & Company’s Global Private Equity Report tracks these trends annually.

Interest rate dynamics have compressed leveraged buyout returns since 2022. SOFR at 5%+ meant an all-in debt cost of 10% to 12% through 2024, which forced sponsors to inject more equity to hit the same IRR. As rates have started to normalize through 2026, deal activity has picked up. LSTA middle market data reported through 2025 showed spreads on senior middle market debt tightening as competition among BDCs and private credit funds intensified.

Named 2024 to 2026 deal comps that illustrate the current market include KKR’s take-private of Envision Healthcare’s remaining assets, Blackstone’s continued platform building in enterprise software, and multiple family office-anchored deals in the $50M to $250M enterprise value band. PR Newswire and SEC filings from public sponsors like Ares Management and Blackstone publish transaction detail sponsors can use for benchmarking.

How does CT Acquisitions help you find the right equity partner?

CT Acquisitions runs the full private equity capital stack raise from mandate through close, sourcing four to eight competitive term sheets from a curated buyer list of PE sponsors, growth equity funds, family offices, and structured capital providers matched to your revenue, EBITDA, sector, and post-close role preferences. Our process typically closes 10 to 26 weeks depending on process breadth and diligence complexity.

The mechanics are straightforward. We start with a mandate call, a fit assessment of your business against current market appetite, and a fee proposal. If you engage, we launch quality of earnings, draft the CIM and teaser, build the buyer list, and manage the entire outreach through LOI. We do not accept representation payments from sponsors, which means our alignment is with you as seller, not with any buyer paying us to source deals.

What separates the CT process from a generic sell-side engagement is the specificity of the buyer list. For an LMM business under $10M EBITDA, we typically curate 40 to 90 buyers, including 10 to 20 family offices most owners have never heard of and 10 to 15 growth-focused PE sponsors that would not respond to a cold email from a first-time raiser. The buyer list is where advisor value shows up.

See our M&A advisory pillar, buy-side M&A advisory, and LMM M&A advisor guide for how we structure engagements. See the Raise Capital hub for the full menu of instruments we advise on, from senior debt through preferred equity through majority recap.

How do you choose among competing advisors?

Choose your private equity capital stack advisor on three criteria: relevant LMM transaction experience in your revenue and sector band, the specificity and quality of their buyer list, and the alignment of their fee structure with your outcome. Verify with references from three closed sellers in the last 24 months. Axial’s 2024 platform data reported that roughly 4,000 investment banks and M&A advisors serve the LMM in North America, and quality varies widely.

Experience matters at the sector and size band level, not the raw firm brand. A bulge bracket bank that closed 200 mega-cap deals last year may or may not have relevant experience for your $8M EBITDA specialty distribution business. Ask specifically for closed comparable transactions in your sector in the last 36 months, and speak directly with two or three of those sellers.

Buyer list quality is the single biggest differentiator. Ask any prospective advisor how many buyers they would run to in your process, what percentage would be strategic vs financial, and how many family offices they have direct partner-level relationships with. A generic advisor will pitch you a canned 50-buyer list. A specialized advisor will walk you through 80 specific firms and why each is a fit.

Fee alignment closes the loop. A retainer-heavy structure with a small success fee misaligns incentives, since the advisor gets paid whether or not the deal closes. A modest retainer with a Lehman-scale success fee credited against retainer keeps the advisor motivated to close at max price. Beware advisors who push for percentage-of-EBITDA-uplift bonuses layered on top of a Lehman, which can compound into fees well above market.

2024 to 2026 named deal comps for reference

Named 2024 to 2026 LMM and middle market deal comps help calibrate what your business could clear in the market. Sponsors like Audax, Riverside, and Genstar closed dozens of platform and add-on deals in the $30M to $500M EV band across 2024 and 2025, per their published portfolio pages and PR Newswire announcements. Family offices like the Pritzker Organization anchored several $75M+ deals in the industrial and specialty distribution verticals.

Buyer / sponsor	Target sector	Deal type	Reported year
Audax Private Equity	Healthcare services	Platform, LMM	2024
Riverside Company	Specialty industrial	Add-on program	2024 to 2025
Kian Capital	Consumer services	Platform, LMM	2024
Genstar Capital	Software, tech-enabled	Platform, mid market	2025
Trivest Partners	Founder-led services	Recap	2024
Ares Management	Various middle market	Unitranche	2024 to 2025
Golub Capital	Various middle market	Unitranche, senior	2024 to 2025
Summit Partners	Growth software	Minority growth	2024 to 2025
TA Associates	Growth software, services	Minority growth	2025
Blackstone Credit	Middle market debt	Direct lending	2024 to 2026

Sourcing your own comps is worth the effort. Bain & Company, PwC, PitchBook, and Preqin publish quarterly LMM and middle market transaction reports. GF Data specifically focuses on the $10M to $500M EV band with quarterly reports on leverage, valuation, and terms. See GF Data and PitchBook for benchmark data most advisors reference in pitches.

Every named 2024 to 2026 transaction cited here is publicly reported through the sponsor’s own portfolio page, a PR Newswire release, SEC filing (for public sponsors like Ares, Blackstone, and KKR), or a trade press publication like PE Hub, Axios Pro Rata, or Middle Market Growth. Sponsors that decline to publicly announce deals typically still list them on their portfolio pages within 60 to 120 days of close.

The bottom line on the private equity capital stack

The private equity capital stack is a set of layered instruments, not a single product, and getting the mix right is worth millions of dollars over a five to seven year hold. LMM operators who run a competitive process, negotiate the term sheet with a specialist advisor, and structure rollover with tax efficiency in mind consistently outperform sellers who accept the first proprietary LOI. GF Data has reported that competitive processes clear 0.5x to 1.5x turns of EBITDA above single-buyer sales.

If you are within 12 to 24 months of a raise or a sale, the highest-leverage move you can make right now is engaging quality of earnings work and starting to interview advisors. Both take 30 to 90 days to execute properly, and both are common bottlenecks that push transaction timelines by a full quarter when left until the last minute.

The wrong move is picking your advisor on brand alone or, worse, running the process yourself to save fees. GF Data’s decade of transaction terms reporting is consistent: competitive processes clear at meaningfully higher multiples, and the advisor fee is almost always recovered inside the improved outcome. That is the single most important number to know when you are deciding whether to hire.

Frequently asked questions

What is a typical private equity capital stack for a $10M EBITDA business?

A representative 2026 lower middle market stack for a $10M EBITDA business at a 7.5x multiple would combine roughly 3.5x senior or unitranche debt, 0.5x to 1.0x mezzanine, and 3.0x to 3.5x sponsor common equity, with 15% to 25% management rollover inside the common layer. GF Data has reported blended leverage in that range across its LMM sample for several quarters.

How much of my company do I give up in a private equity recap?

In a majority recap, the sponsor would typically take 60% to 80% of common equity, and management would roll 10% to 35% of prior ownership into new common. In a minority growth recap from a firm like Summit Partners or TA Associates, the sponsor may take 20% to 40% and the founder retains control. Preferred equity does not dilute common on day one but sits ahead of it in returns.

What is the difference between mezzanine debt and preferred equity in a PE stack?

Mezzanine is subordinated debt with a cash coupon plus PIK, warrants, and a fixed maturity, and it sits below senior debt but above equity in the waterfall. Preferred equity has no fixed maturity, accrues a PIK dividend, and includes a liquidation preference plus a minimum multiple hurdle. Mezzanine holders push for interest servicing, preferred holders push for exit.

How long does a private equity capital raise take for a lower middle market company?

A CT Acquisitions process would typically run 10 to 14 weeks from CIM launch to signed LOI, and another 8 to 12 weeks through diligence to close. Faster processes usually leave value behind because they short the competitive tension. Slower processes usually signal a stale market read or a diligence problem that surfaced late.

Do I need an investment banker or can I go direct to a private equity firm?

You can go direct, and roughly one third of proprietary LMM deals close that way per Axial’s 2024 platform data. But single-buyer processes typically clear 0.5x to 1.5x turns of EBITDA below competitively marketed deals in the GF Data set. A banker or M&A advisor manufactures the competitive tension that moves multiple, and their fee is usually recovered inside the improved price.

What is a rollover equity investment in a private equity deal?

Rollover equity is the portion of your after-tax proceeds you reinvest in the new post-close entity, usually alongside the sponsor’s common equity on the same terms. A 20% rollover on a $60M sale would put $12M of new common equity behind the transaction. Rollover aligns management incentives and captures the second bite at exit, which often exceeds the first bite on a per-share basis.

What is a fair advisor fee to sell my LMM business?

A lower middle market sell-side advisor fee typically ranges from 1% to 5% of enterprise value, structured as a Lehman or modified Lehman scale with a monthly retainer credited against the success fee. Deals below $10M usually carry the highest percentage. A well-run process usually generates enough incremental price to cover the fee two or three times over.

What does CT Acquisitions charge to help me find the right equity partner?

CT Acquisitions charges a modest engagement retainer plus a success fee tied to closing, sized to your transaction range. The retainer is credited against the success fee. We prefer to align on outcome, so the majority of our compensation is contingent on a closed deal you are happy with. Contact us for a fee proposal specific to your revenue and EBITDA profile.
