NOG Announces Proposed Reopening of 3.625% Convertible Senior Notes Due 2029

• Reopening of existing 2029 convertible notes provides NOG with incremental strategic flexibility
• A portion of the proceeds will be used to repurchase stock and purchase a hedge overlay intended to offset share dilution until the stock is above $50.87

Northern Oil and Gas, Inc. (NYSE:NOG) (the "Company" or "NOG") today announced its intention to offer, subject to market and other conditions, $150.0 million aggregate principal amount of additional 3.625% convertible senior notes due 2029 (the "new notes") in a private offering to qualified institutional buyers pursuant to Rule 144A under the Securities Act of 1933, as amended (the "Securities Act"). The new notes will be issued under the same indenture as the Company's $500.0 million aggregate principal amount of 3.625% convertible senior notes due 2029 (the "initial notes" and, together with the new notes, the "notes") issued on October 14, 2022 and will form a part of the same series of notes as the initial notes. While the new notes the Company is offering will initially trade under a Rule 144A CUSIP number, the Company expects that once de-legended, the new notes will trade with same CUSIP number as the initial notes. The Company also expects to grant the initial purchasers of the new notes an option to purchase, for settlement within a period of 13 days from, and including, the date new notes are first issued, up to an additional $22.5 million principal amount of new notes.

The Company intends to use a portion of the net proceeds of the offering to fund the cost of entering into the capped call transactions described below. In addition, the Company intends to use a portion of the net proceeds of the offering to repurchase shares of its common stock concurrently with the pricing of the offering in privately negotiated transactions effected through one of the initial purchasers of the new notes or its affiliate, as the Company's agent. The Company intends to use any remaining net proceeds from the offering for general corporate purposes (initially, the repayment of a portion of the outstanding debt under its revolving credit facility). If the initial purchasers exercise their option to purchase additional new notes, the Company expects to use a portion of the net proceeds from the sale of the additional new notes to enter into additional capped call transactions.

The new notes will be senior, unsecured obligations of the Company, will accrue interest payable semi-annually in arrears and will mature on April 15, 2029, unless earlier repurchased, redeemed or converted. Noteholders will have the right to convert their notes in certain circumstances and during specified periods. The Company will settle conversions by paying or delivering, as applicable, cash and, if applicable, shares of its common stock, based on the applicable conversion rate(s).

The notes will be redeemable, in whole or in part (subject to certain limitations), for cash at the Company's option at any time, and from time to time, on or after April 15, 2026 and on or before the 40th scheduled trading day immediately before the maturity date, but only if the last reported sale price per share of the Company's common stock exceeds 130% of the conversion price for a specified period of time. The redemption price will be equal to the principal amount of the notes to be redeemed, plus accrued and unpaid interest, if any, to, but excluding, the redemption date. Notwithstanding the foregoing, the Company will agree not to call any of the new notes issued in the offering for redemption unless those notes are "freely tradable" (as defined in the indenture governing the initial notes) pursuant to the proviso to the first sentence of the definition thereof.

If certain corporate events that constitute a "fundamental change" occur, then, subject to a limited exception, noteholders may require the Company to repurchase their notes for cash. The repurchase price will be equal to the principal amount of the notes to be repurchased, plus accrued and unpaid interest, if any, to, but excluding, the applicable repurchase date.

In connection with the pricing of the new notes, the Company expects to enter into privately negotiated capped call transactions with one or more of the initial purchasers or their respective affiliates and/or other financial institutions (the "counterparties"). The capped call transactions are expected to offset the potential dilution to the Company's common stock upon any conversion of new notes and/or offset any cash payments the Company is required to make in excess of the principal amount of converted new notes, as the case may be, with such offset subject to a cap.

The Company expects that, in connection with establishing their initial hedge of the capped call transactions, the counterparties or their respective affiliates will purchase shares of the Company's common stock and/or enter into various derivative transactions with respect to the Company's common stock concurrently with, or shortly after, the pricing of the new notes, including potentially with certain investors in the new notes. These activities could increase (or reduce the size of any decrease in) the market price of the common stock or the notes at that time. In addition, the counterparties or their respective affiliates may modify their hedge positions by entering into or unwinding various derivatives with respect to the Company's common stock and/or purchasing or selling shares of common stock or other securities of the Company in secondary market transactions following the pricing of the new notes and prior to the maturity of the notes (and are likely to do so during any observation period relating to a conversion of the notes). This activity could also cause or prevent an increase or a decrease in the market price of the common stock or the notes, which could affect the ability of noteholders to convert the notes and, to the extent the activity occurs during any observation period related to a conversion of the notes, could affect the number of shares of the Company's common stock and value of the consideration that noteholders will receive upon conversion of the notes.

The offer and sale of the new notes and any shares of common stock issuable upon conversion of the new notes have not been, and will not be, registered under the Securities Act or any other securities laws, and the new notes and any such shares cannot be offered or sold except pursuant to an exemption from, or in a transaction not subject to, the registration requirements of the Securities Act and any other applicable securities laws. This press release does not constitute an offer to sell, or the solicitation of an offer to buy, the new notes or any shares of common stock issuable upon conversion of the new notes, nor will there be any sale of the new notes or any such shares, in any state or other jurisdiction in which such offer, sale or solicitation would be unlawful.
