The notes will be senior unsecured obligations of Murphy Oil Corporation and will rank equally with all of Murphy Oil Corporation’s other senior unsecured indebtedness from time to time outstanding.

Neither the Securities and Exchange Commission nor any state securities commission has approved or disapproved of these securities or determined if this prospectus is truthful or complete. Any representation to the contrary is a criminal offense.

See “Risk Factors” beginning on page S-14 of this prospectus supplement for a discussion of certain risks that you should consider in connection with making an investment in the notes.

FORWARD-LOOKING STATEMENTS

This prospectus supplement and the accompanying prospectus, including the documents we incorporate by reference, contain forward-looking statements as defined in the Private Securities Litigation Reform Act of 1995. These statements, which express management’s current views concerning future events or results, are subject to inherent risks and uncertainties. Forward-looking statements are generally identified through the inclusion of words such as “aim”, “anticipate”, “believe”, “drive”, “estimate”, “expect”, “expressed confidence”, “forecast”, “future”, “goal”, “guidance”, “intend”, “may”, “objective”, “outlook”, “plan”, “position”, “potential”, “project”, “seek”, “should”, “strategy”, “target”, “will” or variations of such words and other similar expressions. These statements, which express management’s current views concerning future events, results and plans, are subject to inherent risks, uncertainties and assumptions (many of which are beyond our control) and are not guarantees of performance. In particular, statements, express or implied, concerning the Company’s future operating results or activities and returns or the Company’s ability and decisions to replace or increase reserves, increase production, generate returns and rates of return, replace or increase drilling locations, reduce or otherwise control operating costs and expenditures, generate cash flows, pay down or refinance indebtedness, achieve, reach or otherwise meet initiatives, plans, goals, ambitions or targets with respect to emissions, safety matters or other ESG (environmental/social/governance) matters, make capital expenditures or pay and/or increase dividends or make share repurchases and other capital allocation decisions are forward-looking statements. Factors that could cause one or more of these future events, results or plans not to occur as implied by any forward-looking statement, which consequently could cause actual results or activities to differ materially from the expectations expressed or implied by such forward-looking statements, include, but are not limited to: macro conditions in the oil and gas industry, including supply/demand levels, actions taken by major oil exporters and the resulting impacts on commodity prices; geopolitical concerns; increased volatility or deterioration in the success rate of our exploration programs or in our ability to maintain production rates and replace reserves; reduced customer demand for our products due to environmental, regulatory, technological or other reasons; adverse foreign exchange movements; political and regulatory instability in the markets where we do business; the impact on our operations or market of health pandemics such as COVID-19 and related government responses; other natural hazards impacting our operations or markets; any other deterioration in our business, markets or prospects; any failure to obtain necessary regulatory approvals; any inability to service or refinance our outstanding debt or to access debt markets at acceptable prices; or adverse developments in the U.S. or global capital markets, credit markets, banking system or economies in general, including inflation. For further discussion of factors that could cause one or more of these future events or results not to occur as implied by any forward-looking statement, see “Risk Factors” in this prospectus supplement and in our most recent Annual Report and any subsequent Quarterly Report on Form 10-Q or Current Report on Form 8-K that we file. We undertake no duty to publicly update or revise any forward-looking statements.

NON-GAAP FINANCIAL MEASURES

While Murphy Oil reports financial results in accordance with accounting principles generally accepted in the U.S. (“GAAP”), this prospectus supplement includes certain non-GAAP measures, including EBITDA, Adjusted EBITDA, EBITDAX, Adjusted EBITDAX and PV-10. We define EBITDA as net income (loss) attributable to Murphy before interest, taxes, depreciation, depletion and amortization. We define Adjusted EBITDA as EBITDA before impairment expense, discontinued operations, foreign exchange gains and losses, mark-to-market gains and losses on derivative instruments, accretion of asset retirement obligations and certain other items that management believes affect comparability between periods. We define EBITDAX as EBITDA before exploration expenses. We define Adjusted EBITDAX as EBITDAX before impairment expense, discontinued operations, foreign exchange gains and losses, mark-to-market gains and losses on derivative instruments, accretion of asset retirement obligations and certain other items that management believes affect comparability between periods. All of EBITDA, Adjusted EBITDA, EBITDAX and Adjusted EBITDAX are reported as “attributable to Murphy” and therefore exclude the portion attributable to non-controlling interest. Adjustments to derive Adjusted EBITDA, EBITDAX and Adjusted EBITDAX exclude the portion attributable to

S-iii

non-controlling interest. PV-10 represents present value, discounted at 10% per annum, of estimated future net revenue before income tax of our estimated proved reserves.

Management has included a presentation of EBITDA, Adjusted EBITDA, EBITDAX and Adjusted EBITDAX in this prospectus supplement, because they are used by management to evaluate the Company’s operational performance and trends between periods and relative to industry competitors. In addition, management believes they may be useful to investors and analysts to gain a better understanding of the Company’s financial results and to assess the Company’s ability to service its debt. However, EBITDA, Adjusted EBITDA, EBITDAX and Adjusted EBITDAX are not GAAP measures. You should not consider EBITDA, Adjusted EBITDA, EBITDAX or Adjusted EBITDAX as alternatives to net income, cash flow from operations or any other GAAP financial measure of performance or as indicators of our operating performance. It should also be noted that all companies do not calculate EBITDA, Adjusted EBITDA, EBITDAX and Adjusted EBITDAX in the same manner and, accordingly, EBITDA, Adjusted EBITDA, EBITDAX and Adjusted EBITDAX presented in this prospectus supplement may not be comparable to similarly titled measures used by other companies. We have included reconciliations of EBITDA, Adjusted EBITDA, EBITDAX and Adjusted EBITDAX to net income, the most directly comparable GAAP measure. See “Summary—Summary Consolidated Historical Financial Data.”

Management has included a presentation of PV-10 because it is widely used by professional analysts and sophisticated investors in evaluating oil and gas companies. PV-10 should not be considered as an alternative to the standardized measure as defined under GAAP. We have included a reconciliation of PV-10 to standardized measure of discounted future net cash flows, the most directly comparable GAAP measure. See “Summary—Summary Consolidated Historical Financial Data”.

RISK FACTORS

Investing in the notes involves risks. You should carefully consider all the information set forth in this prospectus supplement, the accompanying prospectus and the documents incorporated by reference herein and therein before deciding to invest in the notes. In particular, we urge you to carefully consider the risk factors set forth below as well as those under the heading “Risk Factors” in our Annual Report.

Risks Relating to the Notes

The notes are structurally subordinated to all liabilities of our subsidiaries and all liabilities guaranteed by our subsidiaries.

The notes are structurally subordinated to all liabilities of our subsidiaries and all liabilities guaranteed by our subsidiaries, including without limitation, their debt and trade payables and our revolving credit facility. As of June 30, 2024, after giving effect to the Refinancing Transactions, we would have had approximately $193.2 million of issued and undrawn letters of credit outstanding, all of which are obligations guaranteed by our subsidiaries and would have been structurally senior to the notes. Additionally, as of June 30, 2024, after giving effect to the Refinancing Transactions, our subsidiaries would have had approximately $1,527 million of indebtedness, trade payables and other accrued current and non-current liabilities outstanding, all of which would rank structurally senior to the notes. None of our subsidiaries has guaranteed or otherwise become obligated with respect to the notes. Our right to receive assets from any of our subsidiaries upon its liquidation or reorganization, and the right of the holders of the notes to participate in those assets, is structurally subordinated to claims of that subsidiary’s creditors. We and our subsidiaries will be permitted under the terms of the indenture governing the notes to incur certain additional indebtedness or otherwise enter into agreements that may restrict or prohibit subsidiaries of ours from the making of distributions, the payment of dividends or the making of loans to us. Even if we were a creditor of any of our subsidiaries, our rights as a creditor would be subordinate to any security interest in the assets of that subsidiary and any debt of that subsidiary senior to that held by us, and our rights could otherwise be subordinated to the rights of other creditors of that subsidiary. Furthermore, we are a holding company and currently conduct substantially all of our operations through our subsidiaries, and our subsidiaries generate substantially all of our operating income and cash flow. As a result, distributions or advances from our subsidiaries are the principal source of the funds we use to meet our debt service obligations. None of our subsidiaries is under any obligation to make payments to us, and any payments to us would depend on the earnings or financial condition of our subsidiaries and various business considerations. Contractual or other legal restrictions may also limit our subsidiaries’ ability to pay dividends or make distributions, loans or advances to us. For these reasons, we may not have access to any assets or cash flows of our subsidiaries to make interest and principal payments on the notes.

Changes in our credit ratings may adversely affect your investment in the notes.

The credit ratings of our indebtedness are an assessment by rating agencies of our ability to pay our debts when due. These ratings are not recommendations to purchase, hold or sell the notes, inasmuch as the ratings do not comment as to market price or suitability for a particular investor, are limited in scope, and do not address all material risks relating to an investment in the notes, but rather reflect only the view of each rating agency at the time the rating is issued. The ratings are based on current information furnished to the ratings agencies by us and information obtained by the ratings agencies from other sources. An explanation of the significance of such rating may be obtained from such rating agency. We cannot assure you that such credit ratings will remain in effect for any given period of time or that such ratings will not be lowered, suspended or withdrawn entirely by the rating agencies, if, in each rating agency’s judgment, circumstances so warrant. Actual or anticipated changes or downgrades in our credit ratings, including any announcement that our ratings are under review for a downgrade, could affect the market value and liquidity of the notes and increase our borrowing costs.

S-14

Despite our current level of indebtedness, we and our subsidiaries may still be able to incur substantially more debt.

We and our subsidiaries may be able to incur substantial additional indebtedness, including additional notes and secured indebtedness, in the future. The indenture governing the notes will not prohibit us from incurring additional indebtedness that is not secured or guaranteed by our subsidiaries. Further, the indenture governing the notes will not fully prohibit our subsidiaries from incurring additional indebtedness or prohibit us or our subsidiaries from incurring secured indebtedness, and any limitations will be subject to a number of significant qualifications and exceptions.

Additionally, the indenture governing the notes will not prevent us or our subsidiaries from incurring obligations that do not constitute indebtedness under the indenture governing the notes.

The notes will be effectively junior to all of our secured indebtedness unless they are entitled to be equally and ratably secured.

The notes will be our senior unsecured obligations and will rank equally with all our other senior unsecured indebtedness. The notes will be effectively subordinated to any secured debt we may incur in the future to the extent of the value of the assets securing such debt. Although the indenture governing the notes will limit our ability to incur secured debt, any limitations will be subject to a number of significant qualifications and exceptions. If we default on the notes, become bankrupt, liquidate or reorganize, any secured creditors could use our assets securing their debt to satisfy their secured debt before you would receive any payment on the notes. If the value of the collateral is not sufficient to pay any secured debt in full, our secured creditors would share the value of our other assets, if any, with you and the holders of other claims against us that rank equally with the notes. As of June 30, 2024, after giving effect to the Refinancing Transactions, we would have had approximately $1,284.9 million of senior unsecured indebtedness outstanding (before unamortized debt issuance cost and discount on notes payable).

We may be unable to purchase the notes upon a change of control triggering event.

The terms of the notes will require us to make an offer to repurchase the notes upon the occurrence of a change of control triggering event at a purchase price equal to 101% of the principal amount of the notes, plus accrued and unpaid interest to the date of the repurchase. The occurrence of certain change of control events (including certain events that would not constitute change of control triggering events) would cause an event of default under our revolving credit facility and therefore could cause us to have to repay amounts outstanding thereunder, and any financing arrangements we may enter into in the future may also require repayment of amounts outstanding in the event of a change of control and therefore limit our ability to fund the repurchase of your notes pursuant to the change of control offer. It is possible that we will not have sufficient funds, or be able to arrange for additional financing, at the time of the change of control triggering event to make the required repurchase of notes. If we have insufficient funds to repurchase all notes that holders tender for purchase pursuant to the change of control offer, and we are unable to raise additional capital, an event of default would occur under the indenture governing the notes. An event of default could cause any other debt that we may have at that time to become automatically due, further exacerbating our financial condition and diminishing the value and liquidity of the notes. We cannot assure you that additional capital would be available to us on acceptable terms, or at all. See “Description of the Notes—Repurchase Upon a Change of Control Triggering Event.”

Your ability to transfer the notes may be limited by the absence of an active trading market, and we cannot assure you that any active trading market will develop for the notes.

The notes are a new issue of securities for which there is no established trading market. Certain of the underwriters have advised us that they intend to make a market in the notes, as permitted by applicable laws and regulations; however, the underwriters are not obligated to make a market in the notes and they may discontinue

S-15

their market-making activities at any time without notice. Therefore, an active market for the notes may not develop or, if developed, may not continue. The liquidity of any market for the notes will depend upon, among other things, the number of holders of the notes, our performance, the market for similar securities, the interest of securities dealers in making a market in the notes and other factors. If a market develops, the notes could trade at prices that may be lower than the initial offering prices of the notes.

Certain actions in respect of defaults taken under the indenture governing the notes by beneficial owners with short positions in excess of their interests in the notes will be disregarded.

By acceptance of the notes, each holder of notes agrees, in connection with any notice of default (as defined in “Description of the Notes”), notice of acceleration or instruction to the trustee (as defined in “Description of the Notes”) to provide a notice of default, notice of acceleration or take any other action (a “Noteholder Direction”), to (i) deliver a written representation to the Company and the trustee that such holder and any of its affiliates acting in concert with it in connection with its investment in the notes (other than Screened Affiliates (as defined in “Description of the Notes”)) are not (or, in the case such holder is DTC or its nominee, that such holder is being instructed solely by beneficial owners that (together with such affiliates) are not) Net Short (as defined under “Description of the Notes”) and (ii) provide the Company with such other information as the Company may reasonably request from time to time in order to verify the accuracy of such holder’s representation within five business days of request therefor. Holders of the notes, including holders that have hedged their exposure to the notes in the ordinary course and not for speculative purposes, may not be able to make such representations or provide the requested additional information. These restrictions may impact a holder’s ability to participate in Noteholder Directions.

S-16

USE OF PROCEEDS

We expect the net proceeds from this offering of notes to be approximately $591.8 million, after deducting underwriting discounts and other estimated expenses of the offering. We intend to use the net proceeds from this offering, together with cash on hand, to fund the Tender Offers and any related premiums, fees and expenses. The foregoing is not an offer to purchase or a solicitation of an offer to sell the Tender Notes. See “Summary—Recent Developments—Concurrent Tender Offers.”

Certain of the underwriters and/or their affiliates are holders of our Tender Notes, and may receive their proportionate share of the net proceeds of this offering in connection with the Tender Offers. See “Underwriting.”

S-17

CAPITALIZATION

We have provided in the table below our unaudited consolidated capitalization as of June 30, 2024 and as adjusted to give effect to Refinancing Transactions. See “Summary—Recent Developments” and “Use of Proceeds.”

S-18

DESCRIPTION OF THE NOTES

We have summarized selected provisions of the notes and the indenture governing the notes below. This summary does not purport to be complete and is qualified in its entirety by reference to the indenture governing the notes. This summary supplements and replaces, where inconsistent, the description of the general terms and provisions of debt securities under the caption “Description of Debt Securities” in the accompanying prospectus. As used in the description below, the terms “Murphy Oil Corporation,” “we,” “our,” “us,” “the Company,” “Murphy Oil” and “Murphy” refer to Murphy Oil Corporation only and not to any of its subsidiaries. Certain terms used in this description are defined under the subheading “—Certain Definitions.”

General

The notes will be issued under the indenture dated as of May 18, 2012 (the “Base Indenture”) between Murphy Oil and Regions Bank (as successor to U.S. Bank National Association), as trustee and a supplement to the Base Indenture, to be dated as of October 3, 2024 between Murphy Oil and Regions Bank, as trustee (the “trustee”), hereafter collectively referred to as the “indenture.” The notes offered hereby will vote as a separate class from the other series of notes issued under the Base Indenture, except as otherwise provided in the indenture.

The notes will initially be limited to an aggregate principal amount of $600,000,000.

The notes will mature on October 1, 2032 and will bear interest at 6.000% per year. Interest on the notes will accrue from October 3, 2024. We:

We will issue the notes only in fully registered form, without coupons, in minimum denominations of $2,000 and any integral multiple of $1,000 in excess thereof. The notes will not be subject to any sinking fund, and will be subject to redemption at our option, as described below.

Further Issuances

We may from time to time, without the consent of the existing holders, create and issue additional notes having the same terms and conditions as the notes offered by this prospectus supplement in all respects, except for the issue date, issue price and, under some circumstances, the date of the first payment of interest on the notes, provided that if the additional notes are not fungible with the notes offered by this prospectus supplement for U.S. federal income tax purposes, such additional notes will have a different CUSIP. Additional notes issued in this manner will be consolidated with and form a single series with the previously outstanding notes.

S-19

Optional Redemption

The notes may be redeemed in whole at any time or in part from time to time, at our option, as set forth below.

If the notes are redeemed at any time prior to October 1, 2027, the notes may be redeemed by us, in whole or in part, at our option, at a redemption price equal to the greater of:

plus, in either case, accrued and unpaid interest on the principal amount of the notes being redeemed to, but not including, the redemption date.

On or after October 1, 2027, the notes may be redeemed by us, in whole or in part, at our option, at the redemption prices set forth below (expressed in percentages of principal amount of the notes being redeemed on the redemption date), plus accrued and unpaid interest on the principal amount of the notes being redeemed to, but not including, the redemption date, if redeemed during the 12-month period commencing on October 1 of the years set forth below.

“Treasury rate” means, with respect to any redemption date:

The treasury rate will be calculated on the third business day next preceding the date fixed for redemption (the “calculation date”). “Comparable treasury issue” means the U.S. Treasury security selected by an independent investment banker as having a maturity comparable to the remaining term (“remaining life”) of the notes to be redeemed that would be utilized, at the time of selection and in accordance with customary financial practice, in pricing new issues of corporate debt securities of comparable maturity to the remaining term of such notes.

S-20

“Comparable treasury price” means, with respect to any redemption date, (1) the average of four reference treasury dealer quotations for such redemption date, after excluding the highest and lowest reference treasury dealer quotations, or (2) if the independent investment banker obtains fewer than four such reference treasury dealer quotations, the average of all such quotations.

“Independent investment banker” means J.P. Morgan Securities LLC or its successors, as specified by us, or, if such firm is unwilling or unable to select the comparable treasury issue, an independent investment banking institution of national standing appointed by us.

“Reference treasury dealer” means each of (1) J.P. Morgan Securities LLC or its successors, provided, however, that if the foregoing shall cease to be a primary U.S. government securities dealer in the United States (a “primary treasury dealer”), we will substitute therefor another primary treasury dealer and (2) any three other primary treasury dealers selected by us after consultation with an independent investment banker.

“Reference treasury dealer quotations” means, with respect to each reference treasury dealer and any redemption date, the average, as determined by the independent investment banker, of the bid and asked prices for the comparable treasury issue (expressed in each case as a percentage of its principal amount) quoted in writing to the independent investment banker at 5:00 p.m., New York City time, on the calculation date.

We will deliver electronically or, at our option, mail by first-class mail a notice of redemption to each holder of notes to be redeemed, with a copy to the trustee, at least 15 and not more than 60 days prior to the date fixed for redemption. Notice of any redemption of the notes in connection with a transaction (including an Incurrence of Indebtedness, a Change of Control or other transaction) may, at our discretion, be given prior to the completion thereof. Any redemption or notice of redemption may, at our discretion, be subject to one or more conditions precedent, including completion of a related transaction. If such redemption or purchase is so subject to satisfaction of one or more conditions precedent, such notice shall describe each such condition, and if applicable, shall state that, in our discretion, the redemption date may be delayed until such time (including more than 60 days after the date the notice of redemption was mailed or delivered, including by electronic transmission) as any or all such conditions shall be satisfied (or waived), or such redemption or purchase may not occur and such notice may be rescinded in the event that any or all such conditions shall not have been satisfied (or waived) by the redemption date, or by the redemption date as so delayed. In addition, we may provide in such notice that payment of the redemption price and performance of our obligations with respect to such redemption may be performed by another Person. We will provide written notice to the trustee no later than the close of business on the business day prior to the redemption date if any such redemption has been rescinded or delayed.

Unless we default on payment of the redemption price, interest will cease to accrue on the notes or portions thereof called for redemption on and after the redemption date. If fewer than all of the notes are to be redeemed, the trustee will select, not more than 60 days prior to the redemption date, the particular notes or portions thereof for redemption from the outstanding notes not previously called by such method as the trustee deems fair and appropriate (or, in the case of notes issued in global form, by such method as DTC may require). The redemption price for notes redeemed at any time prior to October 1, 2027 will be calculated by the independent investment banker and we, the trustee and any paying agent for the notes will be entitled to rely on such calculation. The redemption price will otherwise be determined in accordance with the table above, and the trustee shall have no duty to calculate or verify any calculation of any redemption price.

Except as described above, the notes will not be redeemable by us prior to maturity and will not be entitled to the benefit of any sinking fund.

Repurchase Upon a Change of Control Triggering Event

Upon the occurrence of a change of control triggering event with respect to the notes, unless the Company has exercised its right to redeem all of the notes as described under “—Optional Redemption,” each holder of the notes will have the right to require the Company to purchase all or a portion of such holder’s notes

S-21

pursuant to the offer described below (the “change of control offer”), at a purchase price in cash (the “change of control payment”) equal to 101% of the principal amount thereof plus accrued and unpaid interest, if any, to the date of purchase, provided that any payment of interest becoming due on or prior to the change of control payment date (as defined below) shall be payable to the holders of such notes registered as such on the relevant record date.

Within 30 days following the date upon which the change of control triggering event occurs, or at the Company’s option, prior to any change of control but after the public announcement of the pending change of control, the Company will be required to send, electronically or, at our option by first class mail, a notice to each holder of the notes, with a copy to the trustee, which notice will govern the terms of the change of control offer and describe the change of control triggering event. Such notice will state, among other things, the purchase date, which must be no earlier than 30 days nor later than 60 days from the date such notice is mailed or otherwise transmitted, other than as may be required by law (the “change of control payment date”). The notice, if mailed or otherwise transmitted prior to the date of consummation of the change of control, will state that the change of control offer is conditioned on the change of control being consummated on or prior to the change of control payment date.

Upon the change of control payment date, the Company will, to the extent lawful:

The Company will not be required to make a change of control offer if (i) a third party makes such an offer in the manner, at the times and otherwise in compliance with the requirements for such an offer made by the Company and such third party purchases all notes properly tendered and not withdrawn under its offer or (ii) a notice of redemption for all outstanding notes has been given previous to, or concurrently with, the change of control pursuant to the indenture as described above under the caption “—Optional Redemption”, unless and until there is a default in payment of the applicable redemption price.

If holders of not less than 90% in aggregate principal amount of the outstanding notes validly tender and do not withdraw such notes in a change of control offer and we, or any third party making a change of control offer in lieu of us, as described above, purchase all of the notes validly tendered and not withdrawn by such holders, we or such third party will have the right, upon not less than 15 nor more than 60 days’ prior notice (with a copy to the trustee), with such notice given not more than 30 days following the change of control payment date, to redeem all notes that remain outstanding following such purchase at a redemption price equal to the change of control payment plus, to the extent not included in the change of control payment, accrued and unpaid interest, if any, on the notes that remain outstanding to the date of redemption, provided that any payment of interest becoming due on or prior to the redemption date shall be payable to the holders of such notes registered as such on the relevant record date.

“Change of control” means the occurrence of any of the following:

S-22

“Change of control triggering event” means (1) the ratings of the notes is downgraded by any two of the ratings agencies during the 60-day period (the “trigger period”) commencing on the earlier of (i) the occurrence of a change of control or (ii) the first public announcement of the occurrence of a change of control or the Company’s intention to effect a change of control (which trigger period will be extended so long as the ratings of the notes is under publicly announced consideration for possible downgrade by any of the ratings agencies) and (2) the notes are rated below an investment grade rating by any two of the ratings agencies on any date during the trigger period; provided that a change of control triggering event will not be deemed to have occurred in respect of a particular change of control if such ratings agencies do not publicly announce or confirm or inform the trustee in writing at our request that the reduction was the result, in whole or in part, of any event or circumstance comprised of or arising as a result of, or in respect of, the change of control (whether or not the applicable change of control has occurred at the time of the change of control triggering event). Notwithstanding the foregoing, no change of control triggering event will be deemed to have occurred in connection with any particular change of control unless and until such change of control has actually been consummated.

“Fitch” means Fitch Ratings Inc. and its successors.

“Immediate family” of a person means such person’s spouse, children, siblings, parents, mother-in-law and father-in-law, sons-in-law, daughters-in-law, brothers-in-law and sisters-in-law.

“Investment grade” means a rating of Baa3 or better by Moody’s (or its equivalent under any successor rating category of Moody’s), a rating of BBB- or better by S&P (or its equivalent under any successor rating category of S&P), a rating of BBB- or better by Fitch (or its equivalent under any successor rating category of Fitch) or an equivalent investment grade rating from any replacement ratings agency appointed by the Company.

“Moody’s” means Moody’s Investors Service, Inc. and its successors.

S-23

“Murphy family” means (1) (i) the C.H. Murphy Family Investments Limited Partnership; (ii) the estate and descendants of C.H. Murphy, Jr.; (iii) the siblings of the late C.H. Murphy, Jr. and their respective estates and descendants; (iv) the respective immediate family of, immediate family of descendants of and descendants of immediate family of, any individual included in clause (ii) or (iii); (v) any trust established for the benefit of any of the foregoing or any charitable trust or foundation established by any of the foregoing, and the respective trustees, fiduciaries and beneficiaries of any such trust or foundation; and (vi) any corporation, limited partnership, limited liability company or other entity owned by any of the foregoing, or organized to achieve estate planning objectives of any of the foregoing; and (2) any affiliate (as defined in Rule-12b-2 under the Exchange Act) or successor of any of the foregoing.

“Ratings agency” means each of Fitch, Moody’s and S&P; provided, that if any of Fitch, Moody’s and S&P ceases to rate the notes or fails to make a rating of the notes publicly available for reasons outside of the Company’s control, the Company may appoint a replacement for such ratings agency that is a “nationally recognized statistical rating organization” within the meaning of Section 3(a)(62) of the Exchange Act with respect to the notes.

“S&P” means Standard & Poor’s Ratings Services, a division of The McGraw-Hill Companies, Inc., and its successors.

“Voting stock” of any specified person as of any date means the capital stock of such person that is at the time entitled to vote generally in the election of the board of directors of such person.

The Company will comply with the applicable requirements of Rule 14e-1 under the Exchange Act and any other securities laws and regulations thereunder to the extent those laws and regulations are applicable in connection with the repurchase of the notes as a result of a change of control triggering event. To the extent that the provisions of any securities laws or regulations conflict with the change of control offer provisions of the notes, the Company will comply with those securities laws and regulations and will not be deemed to have breached its obligations under the change of control offer provisions of the notes by virtue of any such conflict.

Unless the Company defaults in the change of control payment, on and after the change of control payment date, interest will cease to accrue on the notes or portions of the notes tendered for repurchase pursuant to the change of control offer.

Ranking

The notes will be our senior unsecured obligations and will rank equally in right of payment with all of our other senior unsecured and unsubordinated indebtedness from time to time outstanding.

We currently conduct substantially all of our operations through our subsidiaries, and our subsidiaries generate substantially all of our operating income and cash flow. As a result, distributions or advances from our subsidiaries are the principal source of the funds we use to meet our debt service obligations. Laws or contractual provisions, as well as our subsidiaries’ financial condition and operating requirements, may limit our ability to obtain cash from our subsidiaries that we require to pay our debt service obligations, including payments on the notes. The notes will not be guaranteed by any of our subsidiaries and therefore will be structurally subordinated to all obligations of our subsidiaries, including trade payables and any of our obligations that are guaranteed by any of our subsidiaries. This means that holders of the notes will have a junior position to the claims of creditors of our subsidiaries on their assets and earnings. The notes will also be effectively subordinated to any secured debt we may incur, to the extent of the value of the assets securing that debt. The indenture restricts the amount of debt our subsidiaries can incur or guarantee and restricts our ability to incur secured debt, subject to the limitations described under “Covenants—Limitations on Subsidiary Indebtedness” and “Covenants—Limitations on Liens” below, respectively.

S-24

As of June 30, 2024, after giving effect to the Refinancing Transactions, Murphy Oil would have had approximately $1,284.9 million of senior unsecured indebtedness outstanding (before unamortized debt issuance cost and discount on notes payable) and approximately $193.2 million of issued and undrawn letters of credit outstanding. As of June 30, 2024, after giving effect to the Refinancing Transactions, our subsidiaries would have had approximately $1,527 million of indebtedness, trade payables and other accrued current and non-current liabilities outstanding.

Covenants

Limitations on liens.

Neither we nor any subsidiary will issue, assume or guarantee any Debt secured by a mortgage, lien, pledge or other encumbrance, which are collectively called “mortgages” in the indenture, on any principal property or on any Debt or capital stock of any subsidiary which owns any principal property without providing that the notes will be secured equally and ratably or prior to the Debt.

However, the limitation on liens shall not apply to the following:

S-25

Limitations on subsidiary indebtedness.

We will not permit any of our subsidiaries to Incur any Indebtedness. However, the limitation on Indebtedness of our subsidiaries shall not apply to the following:

S-26

Limitations on sale and lease-back transactions.

Neither we nor any subsidiary will lease any principal property for more than three years from the purchaser or transferee of such principal property (a “Sale and Lease-Back Transaction”). However, the limitation on this type of arrangement shall not apply if:

S-27

Consolidation, Merger or Sale of Assets

We will not merge or consolidate with any other corporation or sell or convey all or substantially all of our assets to any person, unless (i) either we are the continuing corporation, or the successor corporation or the person which acquires by sale or conveyance substantially all our assets (if other than us) will be a corporation organized under the laws of the United States of America or any state thereof and will expressly assume the due and punctual payment of the principal of and interest on all debt securities under the indenture, according to their tenor, and the due and punctual performance and observance of all of the covenants and conditions of the indenture to be performed or observed by us, by supplemental indenture in form reasonably satisfactory to the trustee, executed and delivered to the trustee by such corporation, and (ii) we or our successor corporation, as the case may be, are not, immediately after such merger or consolidation, or such sale or conveyance, in default in the performance of any such covenant or condition of the indenture.

In case of any such consolidation, merger, sale or conveyance, and following such an assumption by the successor corporation, such successor corporation will succeed to and be substituted for us, with the same effect as if it had been named in the indenture. Such successor corporation may cause to be signed, and may issue either in its own name or in our name prior to such succession any or all of the debt securities issuable under the indenture which theretofore had not been signed by us and delivered to the trustee; and, upon the order of such successor corporation instead of us and subject to all the terms, conditions and limitations prescribed in the indenture, the trustee will authenticate and will deliver any debt securities which previously were signed and delivered by our officers to the trustee for authentication, and any debt securities which such successor corporation thereafter causes to be signed and delivered to the trustee for that purpose. All of the debt securities so issued will in all respects have the same legal rank and benefit under the indenture as the debt securities theretofore or thereafter issued in accordance with the terms of the indenture as though all of such debt securities had been issued at the date of the execution of the indenture.

In the event of any such sale or conveyance (other than a conveyance by way of lease) we or any successor corporation which has become such in the manner described above will be discharged from all obligations and covenants under the indenture and the debt securities issued thereunder and may be liquidated and dissolved.

Amendment and Waivers

We and the trustee may from time to time and at any time enter into supplemental indentures without the consent of any holder for one or more of the following purposes:

S-28

With the consent of holders of not less than a majority in aggregate principal amount of the notes outstanding, we and the trustee may, from time to time and at any time, enter into one or more supplemental indentures for the purpose of adding any provisions to or changing in any manner or eliminating any of the provisions of the indenture or of modifying in any manner the rights of the holders of notes. Notwithstanding the preceding sentence, no supplemental indenture may (a) extend the final maturity, or reduce the principal amount, or reduce the rate or extend the time of payment of interest, or reduce any amount payable on redemption of any note or any right of repayment at the option of the holder without the consent of the holder so affected, or (b) reduce the required percentage of holders, the consent of which is required for any such supplemental indenture, without the consent of the holders so affected.

It will not be necessary for the consent of holders to approve the particular form of any proposed supplemental indenture, but it will be sufficient if such consent approves the substance thereof.

In executing an amendment or supplement to the indenture, the trustee shall be entitled to receive and be fully protected in relying upon an officer’s certificate and an opinion of counsel stating that all covenants and conditions precedent to such amendment or supplement have been complied with, that such amendment or supplement is authorized or permitted by the indenture, and, with respect to such opinion of counsel, that the amendment or supplement constitutes the Company’s legal, valid and binding obligation, enforceable against the Company in accordance with its terms.

Events of Default, Notice and Waiver

“Event of default” means any of the following in relation to the notes:

S-29

If any event of default relating to the outstanding notes occurs and is continuing, either the trustee or the holders of at least 25% in principal amount of the outstanding notes may declare the principal and accrued interest of all of the outstanding notes to be due and immediately payable; provided that a notice of default under the preceding clauses (3) and (4) of this covenant must specify the default, demand that it be remediated and state that such notice is a “notice of default” and may not be given with respect to any action taken, and reported publicly or to holders, more than two years prior to such notice of default. Any notice of default, notice of acceleration or instruction to the trustee to provide a notice of default, notice of acceleration or take any other action (a “Noteholder Direction”) provided by any one or more holders (each a “Directing Holder”) must be accompanied by a written representation from each such holder delivered to us and the trustee that such holder is not (or, in the case such holder is DTC or its nominee, that such holder is being instructed solely by beneficial owners that are not) Net Short (a “Position Representation”), which representation, in the case of a Noteholder Direction relating to delivery of a notice of default (a “Default Direction”) shall be deemed a continuing representation until the resulting event of default is cured or otherwise ceases to exist or the notes are accelerated. In addition, each Directing Holder must, at the time of providing a Noteholder Direction, covenant to provide us with such other information as we may reasonably request from time to time in order to verify the accuracy of such noteholder’s Position Representation within five business days of request therefor (a “Verification Covenant”). The trustee shall have no duty whatsoever to provide this information to us or to obtain this information for us. In any case in which the holder is DTC or its nominee, any Position Representation or Verification Covenant required hereunder shall be provided by the beneficial owner of the notes in lieu of DTC or its nominee and the trustee shall be entitled to conclusively rely on such Position Representation and Verification Covenant.

If, following the delivery of a Noteholder Direction, but prior to acceleration of the notes, we determine in good faith that there is a reasonable basis to believe a Directing Holder was, at any relevant time, in breach of its Position Representation and provide to the trustee an officer’s certificate stating that we have filed papers with a court of competent jurisdiction seeking a determination that such Directing Holder was, at such time, in breach of its Position Representation, and seeking to invalidate any event of default that resulted from the applicable

S-30

Noteholder Direction, the cure period with respect to such event of default shall be automatically stayed pending a final and non-appealable determination of a court of competent jurisdiction on such matter. If, following the delivery of a Noteholder Direction, but prior to acceleration of the notes, we provide to the trustee an officer’s certificate stating that a Directing Holder failed to satisfy its Verification Covenant, the cure period with respect to any event of default that resulted from the applicable Noteholder Direction shall be automatically stayed pending satisfaction of such Verification Covenant. Any breach of the Position Representation shall result in such holder’s participation in such Noteholder Direction being disregarded; and, if, without the participation of such holder, the percentage of notes held by the remaining holders that provided such Noteholder Direction would have been insufficient to validly provide such Noteholder Direction, such Noteholder Direction shall be void ab initio, with the effect that such event of default shall be deemed never to have occurred and the trustee shall be deemed not to have received such Noteholder Direction or any notice of such event of default; provided, however, this shall not invalidate any indemnity or security provided by the Directing Holders to the trustee which obligations shall continue to survive.

Notwithstanding anything in the preceding two paragraphs to the contrary, any Noteholder Direction delivered to the trustee during the pendency of an event of default as the result of a bankruptcy or similar proceeding shall not require compliance with the foregoing paragraphs.

For the avoidance of doubt, the trustee shall be entitled to conclusively rely on any Noteholder Direction delivered to it in accordance with the Indenture and shall have no duty to inquire as to or investigate the accuracy of any Position Representation, enforce compliance with any Verification Covenant, verify any statements in any officer’s certificate delivered to it, or otherwise make calculations, investigations or determinations with respect to Derivative Instruments, Net Shorts, Long Derivative Instruments, Short Derivative Instruments or otherwise and shall have no liability for ceasing to take any action, staying any remedy or otherwise failing to act in accordance with a Noteholder Direction during the pendency of relevant litigation or otherwise as set forth above. The trustee shall have no liability or responsibility to the Company, any holder or any other Person in connection with any Noteholder Direction.

With their acquisition of the notes, each noteholder and subsequent purchaser of the notes consents to the delivery of its Position Representation by the trustee to us in accordance with the terms of this section. Each noteholder and subsequent purchaser of the notes waives any and all claims, in law and/or in equity, against the trustee and agrees not to commence any legal proceeding against the trustee in respect of, and agrees that the trustee will not be liable for any action that the trustee takes in accordance with this section, or arising out of or in connection with following instructions or taking actions in accordance with a Noteholder Direction.

We hereby waive any and all claims, in law and/or in equity, against the trustee, and agree not to commence any legal proceeding against the trustee in respect of, and agrees that the trustee will not be liable for any action that the trustee takes in accordance with this section, or arising out of or in connection with following instructions or taking actions in accordance with a Noteholder Direction.

For the avoidance of doubt, the trustee will treat all holders equally with respect to their rights under this section. In connection with the requisite percentages required under this section, the trustee shall also treat all outstanding notes equally irrespective of any Position Representation in determining whether the requisite percentage has been obtained with respect to the initial delivery of the Noteholder Direction. We hereby confirm that any and all other actions that the trustee takes or omits to take under this section and all fees, costs expenses of the trustee and its agents and counsel arising hereunder and in connection herewith shall be covered by our indemnifications under the indemnification section of the indenture.

If an event of default occurs pertaining to events of bankruptcy, insolvency or similar proceedings, the principal amount and accrued interest shall be immediately due and payable without any declaration or other act by the trustee or any holder.

S-31

The indenture provides that the holders of at least a majority in principal amount of the outstanding notes may direct the time, method and place of conducting any proceeding for any remedy available to the trustee, or of exercising any trust or power conferred on the trustee, with respect to the notes. The trustee may act in any way that is consistent with those directions and may decline to act if any of the directions is contrary to law or to the indenture or would involve the trustee in personal liability.

The indenture provides that the holders of at least a majority in principal amount of the notes may on behalf of the holders of all of the outstanding notes waive any past default (and its consequences) under the indenture, except a default (a) in the payment of the principal of or interest on any of the notes, (b) with respect to voluntary or involuntary bankruptcy, insolvency or similar proceedings, or (c) with respect to a covenant or provision of such indenture which, under the terms of such indenture, cannot be modified or amended without the consent of the holders of all of the outstanding notes. In the case of clause (b) above, the holders of at least a majority of all outstanding debt securities under the indenture (voting as one class) may on behalf of all such holders waive a default.

The indenture contains provisions entitling the trustee to be indemnified to its satisfaction by the holders of the notes before proceeding to exercise any right or power under the indenture at the request of those holders.

The indenture requires the trustee to, within 90 days after the occurrence of a default known to it with respect to the notes, give the holders of the notes notice of the default if uncured and unwaived. However, the trustee may withhold this notice if it in good faith determines that the withholding of this notice is in the interest of those holders. However, the trustee may not withhold this notice in the case of a default in payment of principal of or interest on the notes. The term “default” for the purpose of this provision means any event that is, or after notice or lapse of time, or both, would become, an event of default with respect to the notes.

Any time period in the indenture to cure any actual or alleged default or event of default may be extended or stayed by a court of competent jurisdiction.

The indenture requires us to file annually with the trustee a certificate, executed by our officers, indicating whether any of the officers has knowledge of any default under the indenture.

Notices

We will mail notices and communications to the holder’s address shown on the register of the notes with a copy to the trustee.

Paying Agents and Transfer Agents

The trustee will be the paying agent and transfer agent for the notes.

The Trustee

Regions Bank is the trustee for the notes under the indenture. Regions Bank is also a lender under the Company’s revolving credit facility.

Book-Entry Delivery and Settlement

The Depository Trust Company (“DTC”), New York, New York, will act as securities depository for the notes. The notes will be issued as fully-registered securities registered in the name of Cede & Co. (DTC’s partnership nominee) or such other name as may be requested by an authorized representative of DTC. One or more fully-registered certificates will be issued for the notes, in the aggregate principal amount of such issue, and will be deposited with DTC.

S-32

DTC has advised us as follows:

We have provided the following descriptions of the operations and procedures of DTC solely as a matter of convenience. These operations and procedures are solely within the control of DTC and are subject to change by them from time to time.

We expect that under the procedures established by DTC:

The foregoing information concerning DTC and DTC’s book-entry system has been obtained from sources that we believe to be reliable, but none of Murphy Oil, the underwriters or the trustee takes any responsibility for the accuracy of the foregoing information, and you are urged to contact DTC or its participants directly to discuss these matters.

Euroclear and Clearstream will hold interests in the notes on behalf of their participants through customers’ securities accounts in their respective names on the books of their respective depositaries, which are Euroclear Bank, S.A./N.V., as operator of Euroclear, and Citibank, N.A., as operator of Clearstream.

S-33

The laws of some jurisdictions require that purchasers of securities take physical delivery of those securities in definitive form. Accordingly, the ability to transfer interests in the notes represented by a global note to those persons may be limited. In addition, because DTC can act only on behalf of its participants, who in turn act on behalf of persons who hold interests through participants, the ability of a person having an interest in notes represented by a global note to pledge or transfer those interests to persons or entities that do not participate in DTC’s system, or otherwise to take actions in respect of such interest, may be affected by the lack of a physical definitive security in respect of such interest.

So long as DTC or its nominee is the registered owner of a global note, DTC or that nominee will be considered the sole owner or holder of the notes represented by that global note for all purposes under the indenture and under the notes. Except as provided below, owners of beneficial interests in a global note will not be entitled to have notes represented by that global note registered in their names, will not receive or be entitled to receive physical delivery of certificated notes and will not be considered the owners or holders thereof under the indenture or under the notes for any purpose, including with respect to the giving of any direction, instruction or approval to the trustee. Accordingly, each holder owning a beneficial interest in a global note must rely on the procedures of DTC and, if that holder is not a direct or indirect participant, on the procedures of the participant through which that holder owns its interest, to exercise any rights of a holder of notes under the indenture or the global note.

Neither we nor the trustee will have any responsibility or liability for any aspect of the records relating to or payments made on account of notes by DTC, or for maintaining, supervising or reviewing any records of DTC relating to the notes.

Payments on the notes represented by the global notes will be made to DTC or its nominee, as the case may be, as the registered owner of the notes. We expect that DTC or its nominee, upon receipt of any payment on the notes represented by a global note, will credit participants’ accounts with payments in amounts proportionate to their respective beneficial interests in the global note as shown in the records of DTC or its nominee. We also expect that payments by participants to owners of beneficial interests in the global note held through such participants will be governed by standing instructions and customary practice as is now the case with securities held for the accounts of customers registered in the names of nominees for such customers. The participants will be responsible for those payments.

Payments on the notes represented by the global notes will be made in immediately available funds. Transfers between participants in DTC will be effected in accordance with DTC rules and will be settled in immediately available funds.

Cross-market transfers between participants in DTC, on the one hand, and Euroclear or Clearstream participants, on the other hand, will be effected through DTC in accordance with DTC’s rules on behalf of Euroclear or Clearstream, as the case may be, by their depositaries. Cross-market transactions will require delivery of instructions to Euroclear or Clearstream, as the case may be, by the counterparty in that system in accordance with the rules and procedures and within the established deadlines (Brussels time) of that system. Euroclear or Clearstream, as the case may be, will, if the transaction meets its settlement requirements, deliver instructions to its respective depositaries to take action to effect final settlement on its behalf by delivering or receiving interests in the relevant global note in DTC, and making or receiving payment in accordance with normal procedures for same-day funds settlement applicable to DTC. Euroclear and Clearstream participants may not deliver instructions directly to the depositaries for Euroclear or Clearstream.

Because of time zone differences, the securities account of a Euroclear or Clearstream participant purchasing an interest in a global note from a participant in DTC will be credited and reported to the relevant Euroclear or Clearstream participant, during the securities settlement processing day (which must be a business day for Euroclear and Clearstream) immediately following the settlement date of DTC. DTC has advised us that cash received in Euroclear or Clearstream as a result of sales of interests in a global note by or through a

S-34

Euroclear or Clearstream participant to a participant in DTC will be received with value on the settlement date of DTC but will be available in the relevant Euroclear or Clearstream cash account only as of the business day for Euroclear or Clearstream following DTC’s settlement date.

Certificated Notes

We will issue certificated notes to each person that DTC identifies as the beneficial owner of the notes represented by global notes upon surrender by DTC of such global notes if:

Neither we nor the trustee will be liable for any delay by DTC, its nominee or any direct or indirect participant in identifying the beneficial owners of the related notes. We and the trustee may conclusively rely on, and will be protected in relying on, instructions from DTC or its nominee for all purposes, including with respect to the registration and delivery, and the respective principal amounts, of the notes to be issued.

MATERIAL U.S. FEDERAL INCOME TAX CONSIDERATIONS FOR NON-U.S. HOLDERS

The following are the material U.S. federal income tax consequences to non-U.S. Holders (as defined below) of owning and disposing of notes purchased in this offering at the “issue price,” which is the first price at which a substantial amount of the notes is sold to the public, and held as capital assets for U.S. federal income tax purposes.

This discussion does not describe all of the tax consequences that may be relevant to you in light of your particular circumstances, including the potential application of the income accrual rules set forth in Section 451(b) of the Internal Revenue Code of 1986, as amended (the “Code”), alternative minimum tax and “Medicare contribution tax” consequences and differing tax consequences applicable to you if you are, for instance:

If you are a partnership for U.S. federal income tax purposes, the U.S. federal income tax treatment of your partners will generally depend on the status of the partners and your activities. If you are such a partnership and are considering the purchase of notes, or if you are a partner in such a partnership, you are urged to consult your tax adviser about the U.S. federal income tax consequences of purchasing, owning and disposing of the notes.

This summary is based on the Code, administrative pronouncements, judicial decisions and final, temporary and proposed Treasury Regulations, changes to any of which subsequent to the date of this prospectus supplement may affect the tax consequences described herein. This summary does not address all of the tax considerations that may be relevant to investors that purchase the notes and participate in the Tender Offers for our Tender Notes. You are urged to consult your tax advisor if you purchase the notes and participate in the Tender Offers for our Tender Notes. In addition, this summary does not address any specific aspect of state, local or non-U.S. taxation, or any taxes other than income taxes.

You should consult your tax adviser with regard to the application of the U.S. federal tax laws to your particular situation, as well as any tax consequences arising under the laws of any state, local or non-U.S. taxing jurisdiction.

As used herein, the term “non-U.S. Holder” means a beneficial owner of a note that is, for U.S. federal income tax purposes:

S-39

You are not a non-U.S. Holder if you are a non-resident alien individual present in the United States for 183 days or more in the taxable year of disposition, or if you are a former citizen or former resident of the United States, in which case you should consult your tax adviser regarding the U.S. federal income tax consequences of owning or disposing of a note.

Payments on the Notes

Subject to the discussion below under “—Effectively Connected Income,” “—Backup Withholding and Information Reporting,” and “—FATCA,” payments of principal and interest on the notes by the Company or any paying agent to you will not be subject to U.S. federal income or withholding tax, provided that, in the case of interest,

If you cannot satisfy one of the first three requirements described above and interest on the notes is not effectively connected with your conduct of a trade or business in the United States as described below, payments of interest on the notes generally will be subject to withholding tax at a rate of 30%, subject to an applicable income tax treaty providing for a reduced rate.

Sale or Other Taxable Disposition of the Notes

Subject to the discussion below under “—Backup Withholding and Information Reporting,” you generally will not be subject to U.S. federal income or withholding tax on gain realized on a sale, redemption or other taxable disposition of notes, unless the gain is effectively connected with your conduct of a trade or business in the United States as described below, provided, however, that any amounts attributable to accrued interest will be treated as described above under “—Payments on the Notes.”

Effectively Connected Income

If interest or gain on a note is effectively connected with your conduct of a trade or business in the United States (and, if required by an applicable income tax treaty, is attributable to a U.S. permanent establishment maintained by you), you will generally be taxed in the same manner as a United States person. In this case, you will be exempt from the withholding tax on interest discussed above, although you will be required to provide a properly executed IRS Form W-8ECI in order to claim an exemption from withholding. You are urged to consult your tax adviser with respect to other U.S. tax consequences of the ownership and disposition of notes, including the possible imposition of a branch profits tax at a rate of 30% (or a lower treaty rate) if you are a corporation.

Backup Withholding and Information Reporting

Information returns are required to be filed with the IRS in connection with payments of interest on the notes. Unless you comply with certification procedures to establish that you are not a United States person, information returns may also be filed with the IRS in connection with the proceeds from a sale or other

S-40

disposition of a note. You may be subject to backup withholding on payments on the notes or on the proceeds from a sale or other disposition of the notes unless you comply with certification procedures to establish that you are not a United States person or otherwise establish an exemption. The certification procedures required to claim the exemption from withholding tax on interest described above under “—Payments on the Notes,” will satisfy the certification requirements necessary to avoid backup withholding as well. Backup withholding is not an additional tax. The amount of any backup withholding withheld from a payment to you will be allowed as a credit against your U.S. federal income tax liability and may entitle you to a refund, provided that the required information is timely furnished to the IRS.

FATCA

Provisions commonly referred to as “FATCA” impose withholding of 30% on payments of interest on the notes to “foreign financial institutions” (which is broadly defined for this purpose and in general includes investment vehicles) and certain other non-U.S. entities unless various U.S. information reporting and due diligence requirements (generally relating to ownership by U.S. persons of interests in or accounts with those entities) have been satisfied, or an exemption applies. Withholding may also apply to payments of proceeds of sales or redemptions of the notes, although under proposed regulations issued in December 2018 (the preamble to which specifies that taxpayers are permitted to rely on them pending finalization) no withholding will apply on payments of gross proceeds. You should consult your tax advisers regarding the effects of FATCA on your investment in the notes.

UNDERWRITING

Subject to the terms and conditions stated in the underwriting agreement dated the date of this prospectus supplement, the underwriters named below, for whom J.P. Morgan Securities LLC is acting as representative, have severally agreed to purchase, and we have agreed to sell to such underwriters, the principal amount of the notes set forth opposite the names of such underwriters.

The underwriting agreement provides that the obligations of the several underwriters to purchase the notes included in this offering are subject to approval of certain legal matters by counsel and to certain other conditions. The underwriters are obligated to purchase all the notes if they purchase any of the notes. The underwriters may offer and sell the notes through one or more affiliates. The underwriters reserve the right to withdraw, cancel or modify offers to the public and reject orders in whole or in part.

The underwriters propose to offer some of the notes directly to the public at the public offering price set forth on the cover page of this prospectus supplement and some of the notes to certain dealers at the public offering price less a concession not in excess of 0.675% of the principal amount of the notes. The underwriters may allow, and such dealers may reallow, a concession not in excess of 0.450% of the principal amount of the notes on sales to certain other dealers. After the initial offering of the notes to the public, the public offering price and such concessions may be changed. The offering of the notes by the underwriters is subject to receipt and acceptance and subject to the underwriters’ right to reject any order in whole or in part. If the notes are traded, they may trade at a discount from their initial offering price, depending on prevailing interest rates, the market for similar securities, our operating performance and financial condition, general economic conditions and other factors.

The following table shows the underwriting discount to be paid to the underwriters by us in connection with this offering.

The notes are a new issue of securities with no established trading market. We do not currently intend to apply for the listing of the notes on any securities exchange or for quotation of the notes in any dealer quotation system. We have been advised by certain of the underwriters that one or more of them intends to make a market in the notes, but the underwriters are not obligated to do so and may discontinue any market-making activities at any time without notice. We can give no assurance as to the liquidity of the trading market for the notes. If an active public trading market for the notes does not develop, the market price and liquidity of the notes may be adversely affected. If the notes are traded, they may trade at a discount from their initial offering price, depending on prevailing interest rates, the market for similar securities, our operating performance and financial condition, general economic conditions and other factors.

S-42

We estimate that our total expenses for this offering, excluding the underwriting discount, will be approximately $1.5 million.

In connection with the offering, the representative, on behalf of the underwriters, may purchase and sell notes in the open market. These transactions may include over-allotment, syndicate covering transactions and stabilizing transactions. Over-allotment involves syndicate sales of notes in excess of the principal amount of notes to be purchased by the underwriters in the offering, which creates a syndicate short position. Syndicate covering transactions involve purchases of the notes in the open market after the distribution has been completed in order to cover syndicate short positions. Stabilizing transactions consist of certain bids or purchases of notes made for the purpose of preventing or retarding a decline in the market price of the notes while the offering is in progress. Any of these activities may cause the price of the notes to be higher than the price that otherwise would exist in the open market in the absence of such transactions. These transactions may be effected in the over-the-counter market or otherwise and, if commenced, may be discontinued at any time without notice. Neither we nor any of the underwriters make any representation or prediction as to the direction of magnitude of any effect that the transactions described above may have on the price of the notes.

We expect to deliver the notes against payment for the notes on or about October 3, 2024, which will be the tenth business day following the date of the pricing of the notes (“T+10”). Under Rule 15c6-1 under the Exchange Act, trades in the secondary market generally must settle in one business day, unless the parties to the trade expressly agree otherwise. Accordingly, purchasers who wish to trade the notes on any day prior to one business day before delivery hereunder will be required, by virtue of the fact that the notes initially will settle in T+10, to specify an alternative settlement cycle at the time of any such trade to prevent a failed settlement. Purchasers of the notes who wish to trade the notes on any day prior to one business day before delivery hereunder should consult their own advisors.

We have agreed to indemnify the several underwriters against certain liabilities, including certain liabilities under the Securities Act of 1933, as amended, or to contribute to payments the underwriters may be required to make in respect of any of those liabilities.

We have also agreed that, for a period of 15 days from the closing of the offering contemplated by this prospectus supplement, we will not, without the prior written consent of J.P. Morgan Securities LLC, as representative to the underwriters, offer, sell, contract to sell, pledge, or otherwise dispose of (or enter into any transaction which is designed to, or might reasonably be expected to result in the disposition (whether by actual disposition or effective economic disposition due to cash settlement or otherwise) by the Company or any affiliate of the Company or any person in privity with the Company or any affiliate of the Company), including the filing of a registration statement with the SEC in respect of, or establish or increase a put equivalent position or liquidate or decrease a call equivalent position within the meaning of Section 16 of the Exchange Act, any debt securities issued or guaranteed by the Company except for the notes, or publicly announce an intention to effect any such transaction.

In the ordinary course of their respective businesses, certain of the underwriters and the trustee and some of their affiliates have performed and may in the future perform various financial advisory, investment and commercial banking and lending services for us from time to time, including serving as counterparties to certain derivative and hedging arrangements, for which they have received or will receive customary fees. Some of the underwriters or affiliates of some of the underwriters, including affiliates of the representative, J.P. Morgan Securities LLC, and the trustee are, or may in the future serve as, lenders under our revolving credit facility. In addition, certain of the underwriters or their respective affiliates are acting as dealer managers in connection with the Tender Offers, for which they may receive customary fees and/or customary out-of-pocket expense reimbursement, which may be paid using a portion of the net proceeds from this offering.

In addition, in the ordinary course of their various business activities, the underwriters and their respective affiliates may make or hold a broad array of investments and actively trade debt and equity securities

S-43

(or related derivative securities) and financial instruments (including bank loans) for their own account and for the accounts of their customers, and such investment and securities activities may involve securities and instruments of ours or our affiliates. In particular, some of the underwriters or their affiliates hold the Tender Notes for their own account or for the account of their customers. Because we intend to use the net proceeds from this offering to repurchase Tender Notes in the Tender Offers, such underwriters or their affiliates may receive a portion of the proceeds from this offering as a result of the Tender Offers. See “Summary—Recent Developments—Concurrent Tender Offers.” If any of the underwriters or their affiliates has a lending relationship with us, certain of those underwriters and their affiliates routinely hedge, and certain other of those underwriters or their affiliates may hedge, their credit exposure to us consistent with their customary risk management policies. Typically, such underwriters and their affiliates would hedge such exposure by entering into transactions which consist of either the purchase of credit default swaps or the creation of short positions in our securities, including potentially the notes offered hereby. Any such credit default swaps or short positions could adversely affect future trading prices of the notes offered hereby. The underwriters and their respective affiliates may also make investment recommendations or publish or express independent research views in respect of such securities or financial instruments and may at any time hold, or recommend to clients that they acquire, long or short positions in such securities and instruments.

Standard Chartered Bank will not effect any offers or sales of any notes in the United States unless it is through one or more U.S. registered broker-dealers as permitted by the regulations of FINRA.
