Before EOS IM, Mongillo served as CEO and Deputy Chairman of a listed renewable-energy company on the Italian Stock Exchange. Public profile data also links him to leadership roles at TE Wind S.A., Keystone Srl, PROGEFIN S.p.A., CM&F Srl and FCF Srl. He received Il Sole 24 Ore’s “Best Entrepreneur 2014 Career Award.”
His LinkedIn profile lists Il Sole 24 ORE Business School education, including a 2013–2014 Master Executive Corporate Finance & Banking, and a 2012 SDA Bocconi anti-money-laundering certificate.
Investment Thesis & Focus
- EOS IM’s stated mission is to “generate financial value by investing in the real economy” while promoting positive environmental and social impact.
- The firm focuses on two core strategies: Clean Energy Infrastructure and Mid-Market Private Equity.
- In private equity, EOS invests in Italian SMEs with a clear competitive edge and growth opportunities, aiming to accelerate their transition toward sustainability and digital transformation.
- EOS Next Transition Fund II targets Italian SMEs driving decarbonization through three pillars: energy transition, circular economy and sustainable agriculture.
- The fund deploys flexible capital, including majority and minority buy-outs and growth equity, backing niche leaders and first movers with expansion potential and international ambitions.
- Mongillo has described EOS’s PE style as balanced and “risk adverse,” favoring growth projects, low financial leverage and partnerships with founders.
- In clean energy, EOS invests in large-scale solar and wind projects across Europe, with specific focus on Italy, including greenfield, grid-parity and unsubsidized renewable-energy projects.
- Mongillo’s stated view is that sustainability and digitalization are not trade-offs against profitability; he argues they make companies more competitive over the medium and long term.
