As previously announced on April 5, 2021, we were admitted as an anchor investor in Hy24 (the “Hydrogen Fund”). Hy24 is a joint venture between Ardian, a European investment house, and FiveT Hydrogen, a new investment manager specialized purely on clean hydrogen investments. Investments to date include a green steel manufacturing plant that integrates green H2 located in Sweden, upstream e-Methanol and sustainable aviation fuel production in Europe, and green hydrogen production projects (electrolysis) in Europe. Our investment year to date is euro 3.2 million (equivalent to $3.4) making our unfunded commitment euro 44.1 million (equivalent to $48.7). During the twelve months ended December 31, 2023 there was a return of capital of $0.3 from Hy24.

The fund manager of the Hydrogen Fund (the “Management Company”) established a Limited Partners Advisory Committee (the “LPAC”) which consults with and helps advise the Management Company with respect to certain key decisions governing the fund that the Management Company shall make. The LPAC is comprised of up to fifteen (15) members, the

majority of whom are chosen by certain industrial investors and who are (i) representatives of the anchor investors and (ii) subject to any remaining available seats, representatives of the non-anchor investors selected by the Management Company.

Class A1 Shares, which we hold, are entitled to the return of any associated paid-up capital contributions (excluding any subscription premium or default interest, if any), the Preferred Return calculated thereon as described below, and their share of the Hydrogen Fund’s capital gain beyond the Preferred Return in accordance with the order of distributions in the by-laws of the Hydrogen Fund (in each case to the extent of available funds). The “Preferred Return” equals an annual interest rate of seven percent (7%) if fifteen percent (15%) of the Hydrogen Fund’s aggregate capital commitments from all investors is invested in strategic investments; provided, however, that such seven percent (7%) interest rate shall be reduced in a linear fashion to six and one-half percent (6.5%) if twenty percent (20%) of the Hydrogen Fund’s aggregate capital commitments from all investors is invested in strategic investments. The Management Company currently expects that the Hydrogen Fund will attract aggregate capital commitments equal to its hard cap of euro 1.8 billion.

The Hydrogen Fund shall determine the net asset value of each class of its shares at the end of each quarter (including the Class A1 Shares that we hold), which will be used to record the fair value of our investment.

The Hydrogen Fund will have a term of twelve (12) years, commencing from December 16, 2021, subject to certain potential extensions. Investors cannot request the redemption of their shares by the Hydrogen Fund at any time prior to the final liquidation of the fund. Capital calls will be made by the Management Company in accordance with investment opportunities and the financing needs of the Hydrogen Fund’s activities.

The Management Company is required to send capital call requests to investors at least ten (10) business days prior to their deadline for payment. In the event that, following any capital call made by the Management Company, an investor of the Hydrogen Fund does not timely fund all or any portion of its capital commitment required thereby, such investor will be charged interest thereon equal to the Preferred Return plus one-half percent (0.5%), and shall not be entitled to receive distributions from the Hydrogen Fund until it is no longer delinquent.
