NOG Provides Fourth Quarter Update

Northern Oil and Gas, Inc. (NYSE:NOG) ("NOG" or the "Company") today provided an update on a number of business matters including fourth quarter hedging results, an update on ground game transactions and a non-cash impairment charge.

BUSINESS UPDATE

Unrealized mark-to-market gains on derivatives for the fourth quarter were an estimated $84.0 – $88.0 million, driven by changes to the value of the Company's derivatives portfolio. Realized hedge gains were an estimated $70.0 – $72.0 million, driven by the Company's natural gas, crude oil and basis hedges.

The Company continues to execute its policy of protecting its capital program by periodically entering into financial derivative instruments with counterparties to lock in future commodity prices on a portion of its expected production. NOG has added additional hedges since its third quarter report, including hedges to oil, natural gas and Waha, Midland-Cushing and M2 basis hedges. The Company currently has an average of over 45,000 barrels per day of oil hedged for the first half of 2026 and an average of over 40,000 barrels per day of oil hedged for full-year 2026, through a combination of swaps and collars. Additionally, NOG has an average of over 285 MMBtu per day of natural gas hedged for the first half of 2026 and an average of over 295 MMBtu per day of natural gas hedged for full-year 2026, through a combination of swaps and collars. An updated copy of the hedge tables can be found below.

GROUND GAME UPDATE

NOG continued its successful ground game efforts in the fourth quarter with a record 33 ground game transactions, deploying approximately $77.0 million of acquisition and development capital across the Company's four basins adding 1.2 net wells and over 6,000 net acres.

In 2025, the Company deployed approximately $173.5 million of acquisition and development capital across a record 84 ground game transactions, adding 12.8 net wells and over 12,000 acres. These activities will add over 65 net incremental locations across all of NOG's active basins.

NON-CASH IMPAIRMENT

NOG accounts for its assets under the full-cost method under SEC guidelines, as opposed to the Successful Efforts method, which does not perform historical price-based asset tests. Driven by lower average oil prices on a year-over-year basis, the Company expects to take a non-cash impairment charge in the fourth quarter of 2025 of $260 – $270 million under the "ceiling test" of the full cost pool on its assets. This non-cash charge will have no impact on cash flows of the Company.
