New co-investments in OneStream and Septeo

London, 2 March 2026: HgCapital Trust plc ("HgT") today announces new co-investments in OneStream, Inc ("OneStream") and Septeo Group ("Septeo"), totalling approximately £46 million.

On 6 January 2026, HgT announced that it would invest approximately £93m in OneStream, investing alongside other institutional investors via the Hg Saturn 4 fund. Hg has subsequently completed the over-subscribed syndication of $1.5bn of OneStream equity alongside the Hg Saturn 4 fund. As part of the syndication, HgT will invest an additional $9 million (c. £7 million) in OneStream as a co-investor, increasing its aggregate investment in OneStream to approximately £100 million.

In a separate transaction, Hg has also signed the partial sell-down of over ?500 million of equity in Septeo at the 31 December 2025 valuation to a group of institutional investors. As part of this transaction, HgT has taken the opportunity to convert c.?45 million (c. £39 million) of its existing NAV exposure in Septeo via the Hg Genesis 9 fund into fee-free co-investment, by co-investing in a structure alongside the new investors coming into the business.

Together these two transactions, both of which were agreed during a period of heightened volatility in public markets, reflect continued demand in the private markets for Hg's portfolio investments. The transactions have also increased HgT's exposure to fee-free co-investments from c. 10% to 12% of the estimated 31 December 2025 NAV.
