Frequently asked questions

Is IDI a traditional private equity fund or a publicly traded entity?

IDI is a publicly traded company listed on Euronext Paris, making it a permanent-capital vehicle rather than a conventional closed-end fund. This means it does not have finite fund lives or mandatory capital-return schedules. Its balance-sheet equity funds investments directly, and the firm is subject to French listed-company regulations and public disclosure obligations.

What types of deals does IDI typically pursue?

IDI focuses on the French mid-market, targeting majority buyouts, management buy-ins, growth capital injections, and complex situations such as spin-offs or restructurings. The permanent-capital structure allows the firm to hold investments beyond the typical private-equity fund horizon, accommodating longer operational transformations or delayed exit windows.

How does IDI's geographic focus influence its deal pipeline?

IDI concentrates on companies headquartered or operating primarily in France, with occasional exposure elsewhere in continental Europe. Its Paris base and decades-long domestic presence provide access to family-owned businesses, corporate carve-outs, and succession-driven opportunities that often require French-language negotiation and local regulatory familiarity.

What is the advantage of IDI's Euronext listing compared to private fund structures?

The listing provides permanent capital that does not expire, removing the pressure to exit investments on a fund-lifecycle timeline. It also offers liquidity to shareholders and imposes public-company transparency, which can reassure founders and corporate sellers. The trade-off is exposure to stock-market volatility and the administrative overhead of French public-company compliance.
