About Altamir

Altamir is a listed private equity company (Euronext Paris-B, ticker: LTA) founded in 1995 and with a NAV of nearly €1.2bn. Its objective is to provide shareholders with long-term capital appreciation and regular dividends by investing in a diversified portfolio of private equity investments.

Altamir's investment policy is to invest principally via and with the funds managed or advised by Seven2 and Apax, two leading private equity firms that take majority or lead positions in buyouts and growth capital transactions and seek ambitious value creation objectives. In this way, Altamir provides access to a diversified portfolio of fast-growing companies across Seven2' and Apax's sectors of specialisation (Tech & Software, Consumer, Healthcare, Services) and in complementary market segments (mid-sized companies in continental Europe and large companies in Europe, North America and key emerging markets).

Altamir derives certain tax benefits from its status as a SCR ("Société de Capital Risque"). As such, Altamir is exempt from corporate tax and the company's investors may benefit from tax exemptions, subject to specific holding-period and dividend-reinvestment conditions.
