Key Takeaways
- • European and UK firms have captured half of the top 20 positions in the 2025 HEC Paris–Dow Jones Lower MidMarket Buyout Performance Ranking, with Gridiron Capital holding the #1 spot, followed by three UK firms and six EU-based firms in the remaining top 20.
- • Summa Equity, a Swedish dedicated impact fund, has ranked #4 globally in the 2025 Lower MidMarket Buyout Performance Ranking, marking the first time in the 16-year history of the HEC Paris–Dow Jones PE Performance Rankings (since 2009) that an impact-focused fund has entered the top five across any segment.
- • UK and Japan-based firms have broken into the top 10 of the 2024 Growth Capital Performance Ranking for the first time, with Apis Partners (UK) at #2, Sprits (UK) at #7, and Whiz Partners (Japan) at #8, signaling geographic diversification in global private equity performance.
- • Professor Oliver Gottschalg, the ranking's architect at HEC Paris, characterizes the results as evidence of a "levelling global playing field" in lower midmarket PE, stating that "world-class value creation is no longer concentrated in a single geography" and that Summa's performance demonstrates impact-focused strategies can rival established PE firms.
- • Impact investing has demonstrated competitive performance parity with traditional private equity, with Summa Equity's ranking suggesting that measurable social impact and exceptional financial returns are complementary rather than mutually exclusive objectives.
Summary
The 2025 HEC Paris–Dow Jones Lower MidMarket Buyout Performance Ranking reveals a significant geographic shift in private equity dominance, with non-US firms occupying half of the top 20 positions. Gridiron Capital maintains the top ranking, while European and UK-based firms—three from the UK and six from the EU—have consolidated substantial representation in the upper tier. This represents a material challenge to the historical dominance of US-based private equity firms in this segment, indicating that superior deal performance and value creation capabilities are no longer concentrated in a single geographic region.
The most significant development is the entry of Summa Equity, a Swedish dedicated impact fund, into the top five of any HEC Paris–Dow Jones ranking segment. Ranking fourth globally in the Lower MidMarket Buyout Performance Ranking, Summa Equity's inclusion marks a watershed moment in private equity performance measurement. According to Professor Oliver Gottschalg, the architect of the ranking, "The inclusion of a dedicated impact fund in the top five is a watershed moment. It demonstrates that impact-focused strategies are now delivering returns that rival the most established names in private equity." This breakthrough suggests that impact investing—defined by measurable social outcomes alongside financial profit—is no longer a performance constraint but rather a value driver in institutional portfolio construction.
Geographic expansion has also accelerated in the Growth Capital segment. The 2024 ranking marks the first time that UK and Japan-based firms have entered the top 10. Apis Partners, a UK firm, achieved the #2 position, while fellow British firm Sprits ranked #7. Japan's Whiz Partners secured #8, representing the first Asian-based firm to enter the top 10 of the Growth Capital rankings. While US firms still represent 14 of the top 20 firms globally, the reshuffling of positions below the top rank signals an increasingly competitive and globalized capital markets environment, as noted by Professor Gottschalg.
The broader implication for institutional investors and alternative asset managers is twofold. First, deal sourcing and manager selection strategies should account for geographic diversification in private equity performance; European and UK-based platforms have demonstrated competitive capability in both lower midmarket buyouts and growth capital deployment. Second, the performance of dedicated impact funds suggests that environmental, social, and governance (ESG) integration strategies have matured sufficiently to compete with traditional return optimization frameworks, potentially reshaping capital allocation decisions within institutional LP portfolios.
