Deal Sizes and Capital Structures Across the Mid-Market PE Spectrum

Not all mid-market PE deals are built alike. This episode breaks down how deal sizes, leverage, equity checks, rollovers, and earnouts diverge dramatically across the lower, core, and upper mid-market bands — with hard data to back it up.

Show Notes

The term "mid-market" gets applied to deals ranging from $5 million to nearly $1 billion in enterprise value — yet the mechanics of a lower mid-market carve-out and an upper mid-market platform recapitalization have almost nothing in common. This episode of PrivateEquityInvestor.com draws on 2025 data from GF Data, LSEG LPC, SRS Acquiom, Goodwin, and PGIM to map exactly how capital structures, leverage ratios, equity checks, and deal terms shift across three distinct bands of the mid-market spectrum. The full reference guide behind this episode is available in the mid-market deal sizes and structures article on the site.

The episode walks through each band — lower mid-market ($5M–$100M EV), core mid-market ($100M–$500M EV), and upper mid-market ($500M–$1B EV) — and examines how the structural differences at each tier cascade into almost every element of a deal. Here's what's covered:

• Purchase price multiples by tier: GF Data figures show average EBITDA multiples jumping from 6.4× at the smallest deal sizes to 10.3× in the $100M–$250M range — a size premium that drives nearly every downstream structural decision.
• Equity check sizing and composition: Sponsor equity contributions have risen from roughly 35% of the capital stack in 2019 to around 50% today, meaning a $750M upper mid-market deal now typically requires $340M–$400M in equity — the level at which club structures, co-investment sleeves, and large single-fund commitments become operational necessities rather than options.
• Debt structures and leverage compression: Private credit financed 85% of leveraged buyouts in 2024, and single unitranche loans have largely displaced senior-plus-mezzanine structures in the lower mid-market. Across all tiers, the episode stresses scrutinizing add-back-adjusted EBITDA against reported leverage multiples — a deal closing at 4.5× reported EBITDA can be closer to 5.3× on trailing cash earnings. Listeners evaluating debt arrangements can use the Debt Service Coverage Ratio (DSCR) Calculator to stress-test coverage at close.
• Rollover equity trends: Goodwin data shows rollover inclusion in mid-market deals rose from 46% in 2020 to 57% in 2023, with average rollover equity as a share of total EV climbing from 14% to nearly 17% by Q3 2025 — a direct response to tighter leverage availability. Rollover sizing conventions differ meaningfully by tier, from founder-led lower mid-market deals to secondary buyouts where selling sponsors are distributing, not reinvesting.
• Earnout mechanics and frequency: SRS Acquiom's 2026 Deal Terms Study found earnouts present in 24% of private-target deals overall, but in 35% of the smallest transactions. The episode highlights the structural questions practitioners must ask: what metric governs the earnout, who controls the accounting policy behind it, and what happens on a change of control mid-period.
