The aggregate cost of such equipment is approximately $278.3 million. The Reservation Agreement was assigned to Stonebriar in connection with entry into the Lease Documents. The cost of the investment may be financed under the Lease Documents as progress payments become due. We expect deliveries to begin in late 2026. Pursuant to the Reservation Agreement, the parties negotiated and entered into an engineering, procurement and construction agreement governing the terms of the manufacture, delivery and installation for a certain portion of the equipment, which provided for an additional estimated $53.7 million commitment for balance of plant and labor costs and contains customary representations, warranties and agreements of the parties, indemnification obligations and other customary terms and conditions associated therewith. The Reservation Agreement and terms and conditions of sale also contain customary agreements of the parties and customary terms and conditions. As of June 30, 2026, there has been $124.3 million spent and $207.7 million outstanding on these commitments. The Company expects substantially all of this amount to be incurred over the second half of 2026 and 2027, with the timing within that period dependent on project execution and deliveries.
