NWN Renewables Purchase Agreements
NWN Renewables is an unregulated subsidiary of NW Holdings established to pursue investments in RNG activities. NWN Renewables, through its subsidiary Ohio Renewables, executed agreements with a subsidiary of EDL, a global producer of sustainable distributed energy, to secure RNG supply from two production facilities that convert landfill waste gases to RNG. This arrangement consists of a development agreement, an exclusive use agreement, a purchase agreement, and various guarantees.
Under the development agreement, the EDL subsidiary was responsible for the development and construction of the facilities. The first facility was completed and commenced delivery of RNG to Ohio Renewables in September 2024. Upon reaching this milestone, Ohio Renewables paid $26.0 million to the EDL subsidiary. The second facility was completed and commenced delivery of RNG to Ohio Renewables in December 2024 at which point Ohio Renewables made an additional payment of $25.4 million to the EDL subsidiary. The payments were recorded as long-term prepaid assets and will be amortized based on the volumes delivered over the life of the agreement.
Under the purchase agreement, Ohio Renewables and the subsidiary of EDL executed agreements for Ohio Renewables to purchase up to an annual specified amount of RNG produced by the EDL facilities over a 20-year period at a contractually specified price. In December 2025, Ohio Renewables entered into an agreement to purchase up to an annual specified amount of RNG produced by the EDL facilities from a separate investment-grade counterparty over an 11-year period at a contractually specified price. Purchase volumes are variable based on production, and purchases may not exceed contracted amounts. We currently estimate the amount of RNG purchases based on prices and estimated production volumes specified in the agreements to be $20.9 million in 2026, $31.4 million in 2027, $31.6 million in 2028, $30.8 million in 2029, $31.4 million in 2030 and $599.3 million thereafter through 2044. In 2025, purchases totaled $14.5 million.

Per the guarantee, NW Holdings unconditionally and irrevocably guarantees the timely payment and performance when due of all obligations of Ohio Renewables.
