UPDATE 1: In reference to the Deferred Collection Agreement referenced in paragraph two below, this update is to provide additional clarification regarding the Deferred Collection Agreement.

1.    To ensure inclusion in the January 2026 billing cycle, signed Deferred Collection Agreements must be returned to Northern by January 23, 2026. Agreements returned after this date will be processed on a commercially reasonable basis to accommodate January billing.

2.    To ensure accurate crediting, billing and tracking of deferred balances, Deferred Collection Agreements are not applicable to temporary capacity release transactions.

3.    Customers belonging to a rate case shipper group may sign Deferred Collection Agreements. There is no requirement that all members of a shipper group sign Deferred Collection Agreements for individual customers in the shipper group to participate.

If you have any questions, please contact Tom Halpin or your marketing representative.

ORIGINAL NOTICE: Northern will be filing a motion to implement the suspended tariff rates associated with Docket No. RP25-989 to be effective January 1, 2026. In furtherance of settlement discussions, Northern is also proposing to implement lower interim reservation rates compared to filed rates for the market area and the field area. Northern's proposed interim rates reflect an approximate 17% reduction below the Market Area filed rates and a 29% reduction below the Field Area filed rates. The interim transportation rates that Northern expects to implement are presented on the table below. At the present time, Northern is still evaluating the storage rates. Northern anticipates that the interim storage rates will be close to the filed storage rates.

As it has done in the past, Northern is offering customers on Northern's pipeline system an opportunity to enter into a Deferred Collection Agreement. In exchange for customer’s agreement that it sees a path to settlement, Northern will agree to defer collection of the difference between the billed interim rates (applicable tariff rates) and the proposed settlement rates beginning January 1, 2026, as more fully described in the Deferred Collection Agreement.
