We expect that delivery of the notes will be made against payment therefore on or about the closing date specified on the cover page of this prospectus supplement, which will be the business day following the date of this prospectus supplement. This settlement cycle is referred to as “T+ .” Under Rule 15c6-1 under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), trades in the secondary market generally are required to settle in one business day, unless the parties to any such trade expressly agree otherwise. Accordingly, purchasers who wish to trade notes prior to the date that is one business day preceding the settlement date, will be required, by virtue of the fact that the notes initially will settle T+ , to specify an alternate settlement cycle at the time of any such trade to prevent a failed settlement. Purchasers of notes who wish to trade notes prior to the date that is one business day preceding the settlement date should consult their own advisors.

TABLE OF CONTENTS

FORWARD-LOOKING STATEMENTS

This prospectus supplement and the accompanying base prospectus include “forward-looking statements” within the meaning of Section 27A of the Securities Act of 1933 (the “Securities Act”) and Section 21E of the Exchange Act. Forward-looking statements include our current expectations or forecasts of future events, including matters relating to, armed conflict between Russia and Ukraine, instability in the Middle East and Venezuela and changes in China-Taiwan relations, along with the effects of the current global economic environment, and the impact of each on our business, financial condition, results of operations and cash flows, actions by, or disputes among or between, members of OPEC+ and other foreign oil-exporting countries, market factors, market prices, our ability to meet debt service requirements, our ability to continue to pay cash dividends, the amount and timing of any cash dividends and our sustainability initiatives. Forward-looking and other statements in this prospectus supplement and the accompanying base prospectus regarding our environmental, social and other sustainability plans and goals are not an indication that these statements are necessarily material to investors or required to be disclosed in our filings with the SEC. In addition, historical, current, and forward-looking environmental, social and sustainability-related statements may be based on standards for measuring progress that are still developing, internal controls and processes that continue to evolve, and assumptions that are subject to change in the future. Forward-looking statements often address our expected future business, financial performance and financial condition, and often contain words such as “aim,” “predict,” “should,” “expect,” “could,” “may,” “anticipate,” “intend,” “plan,” “ability,” “believe,” “seek,” “see,” “will,” “would,” “estimate,” “forecast,” “target,” “guidance,” “outlook,” “opportunity” or “strategy.”

Although we believe the expectations and forecasts reflected in our forward-looking statements are reasonable, they are inherently subject to numerous risks and uncertainties, most of which are difficult to predict and many of which are beyond our control. No assurance can be given that such forward-looking statements will be correct or achieved or that the assumptions are accurate or will not change over time. Particular uncertainties that could cause our actual results to be materially different than those expressed in our forward-looking statements include:

•

reduced demand for natural gas, oil and natural gas liquids;

•

negative public perceptions of our industry;

•

competition in the natural gas and oil exploration and production industry;

•

the volatility of natural gas, oil and natural gas liquids (“NGL”) prices, which are affected by general economic and business conditions, as well as increased demand for (and availability of) alternative fuels and electric vehicles;

•

risks from regional epidemics or pandemics and related economic turmoil, including supply chain constraints;

•

write-downs of our natural gas and oil asset carrying values due to low commodity prices;

•

significant capital expenditures are required to replace our reserves and conduct our business;

•

our ability to replace reserves and sustain production;

•

uncertainties inherent in estimating quantities of natural gas, oil and NGL reserves and projecting future rates of production and the amount and timing of development expenditures;

•

drilling and operating risks and resulting liabilities;

•

our ability to generate profits or achieve targeted results in drilling and well operations;

•

leasehold terms expiring before production can be established;

•

risks from our commodity price risk management activities;

uncertainties, risks and costs associated with natural gas and oil operations;

•

our need to secure adequate supplies of water for our drilling operations and to dispose of or recycle the water used;

TABLE OF CONTENTS

SUMMARY

This summary highlights information contained elsewhere in this prospectus supplement and the accompanying base prospectus. It does not contain all of the information that you should consider before making an investment decision. You should read the entire prospectus supplement, the accompanying base prospectus and the documents incorporated by reference for a more complete understanding of this offering. See “Risk Factors” beginning on page S-10 of this prospectus supplement and page 1 of the accompanying base prospectus for more information about important risks that you should consider before investing in the notes.

Unless otherwise provided or the context otherwise requires, references to “Expand Energy,” “we,” “our,” “us” and the “Company” refer to Expand Energy Corporation and its consolidated subsidiaries.

Expand Energy Corporation

Expand Energy is the largest independent natural gas producer in the United States, based on net daily production, and is focused on responsibly developing an abundant supply of natural gas, oil and NGLs to expand energy access for all. Our operations are located in Louisiana and Texas in the Haynesville and Bossier Shales (“Haynesville”), in Pennsylvania in the Marcellus Shale (“Northeast Appalachia”), and in West Virginia and Ohio in the Marcellus and Utica Shales (“Southwest Appalachia”) and include working interests in approximately 6,600 gross natural gas and oil wells.

Our strategy is to create resilient shareholder value through the responsible development of our significant resource plays while continuing to be a leading provider of natural gas to growing markets. We continue to focus on improving margins through operating efficiencies, marketing and commercial efforts and financial discipline and improving our safety and sustainability performance. To accomplish these goals, we intend to allocate our human resources and capital expenditures to projects we believe offer the highest cash return on capital invested, to deploy leading drilling and completion technology throughout our portfolio, and to take advantage of acquisition and divestiture opportunities to strengthen our portfolio. We also intend to continue to invest in projects designed to reduce the environmental impact of our production activities.

Recent Developments

Twin Eagle Acquisition

On July 24, 2026, we entered into an agreement and plan of merger with Twin Eagle Holdings N.A., LLC (“Twin Eagle”), a provider of natural gas marketing and logistics services, and one of our wholly owned subsidiaries whereby we will acquire Twin Eagle (the “Twin Eagle Acquisition”). The transaction is subject to customary closing conditions, including certain regulatory approvals, and is expected to close in the third quarter of 2026. The purchase price is approximately $1.25 billion, subject to typical purchase price adjustments, including for working capital. The Company expects to fund the transaction through a combination of cash on hand and borrowings under our revolving credit facility. Twin Eagle Resource Management, LLC (“TERM”) and Twin Eagle Resource Management Canada, LLC (“TERM Canada” and, together with TERM, the “TERM Subsidiaries”) are party to a senior secured credit facility with an elected capacity of $1.0 billion as of June 30, 2026, which matures in May 2027 (the “Twin Eagle Credit Facility”) and which will remain outstanding as an obligation of the TERM Subsidiaries following the completion of the Twin Eagle Acquisition. Neither Expand nor its subsidiaries (other than the TERM Subsidiaries) are expected to provide guarantees of such facility. After the completion of the Twin Eagle Acquisition, we expect for the Twin Eagle Credit Facility to remain outstanding for a limited period of time, after which we intend to terminate the facility once borrowings and outstanding letters of credit are canceled. See “Description of the Notes — Ranking.” Following the close of the Twin Eagle Acquisition, key members of the Twin Eagle management team will continue with the Company. All conditions precedent, other than those satisfied concurrently with closing, have been satisfied, and we anticipate the closing of the Twin Eagle Acquisition will occur imminently. We anticipate a portion of the Twin Eagle Acquisition purchase price will be funded with borrowings under our revolving credit facility.

(a)

Adjusted EBITDAX is a Non-GAAP measure and is defined as net income (loss) before interest expense, income tax expense (benefit), depreciation, depletion and amortization expense, exploration expense, unrealized (gains) losses on derivatives, separation and other termination costs, (gains) losses on sales of assets, and certain items management believes affect the comparability of operating results. Adjusted EBITDAX is presented as it provides investors an indication of the Company’s ability to internally fund exploration and development activities and service or incur debt. Adjusted EBITDAX should not be considered an alternative to, or more meaningful than, net income (loss) as presented in accordance with GAAP.

Management believes Adjusted EBITDAX is a meaningful adjunct to earnings calculated in accordance with GAAP because (a) management uses this financial measure to evaluate the Company’s trends and performance, (b) this financial measure is comparable to estimates provided by certain securities analysts, and (c) items excluded generally are one-time items or items whose timing or amount cannot be reasonably estimated.

(b)

Net Debt is a Non-GAAP measure and is defined as GAAP total debt excluding premiums, discounts, and deferred issuance costs less cash and cash equivalents. Net Debt is useful to investors as a widely understood measure of liquidity and leverage, but this measure should not be considered as an alternative to, or more meaningful than, total debt presented in accordance with GAAP.

TABLE OF CONTENTS

RISK FACTORS

An investment in the notes involves risks. You should carefully consider all of the information contained in this prospectus supplement, the accompanying base prospectus and the documents incorporated by reference as provided under “Incorporation by Reference,” including our most recent Annual Report on Form 10-K and our Quarterly Reports on Form 10-Q, and the risk factors described under “Risk Factors” therein, as applicable. This prospectus supplement, the accompanying base prospectus and the documents incorporated by reference also contain forward-looking statements that involve risks and uncertainties. See “Forward-Looking Statements.” Our actual results could differ materially from those anticipated in the forward-looking statements as a result of certain factors, including the risks described elsewhere in this prospectus supplement, in the accompanying base prospectus and in the documents incorporated by reference. If any of these risks occur, our business, financial condition or results of operation could be adversely affected.

Risks Related to this Offering and the Notes

The notes will be effectively subordinated to any secured debt of ours, and, in the event of our bankruptcy or liquidation, holders of the notes will be paid from any assets remaining after payments to any holders of any secured debt we may have. In addition, the notes will be structurally subordinated to any debt of our subsidiaries.

The notes will be our general unsecured senior obligations, and effectively subordinated to any secured debt that we may have, to the extent of the value of the assets securing that debt. The notes and the indenture under which the notes will be issued permit us to incur secured debt provided certain conditions are met. If we are declared bankrupt or insolvent, or are liquidated, the holders of our secured debt will be entitled to be paid from our assets securing their debt before any payment may be made with respect to the notes. If any of the preceding events occur, we may not have sufficient assets to pay amounts due on our secured debt and the notes.

None of our subsidiaries will guarantee the notes initially, and as a result, the notes will be structurally subordinated to the claims of all creditors, including unsecured indebtedness, trade creditors and tort claimants, of those subsidiaries. In the event of the insolvency, bankruptcy, liquidation, reorganization, dissolution or winding up of the business of any of our subsidiaries, creditors of such subsidiaries would generally have the right to be paid in full before any distribution is made to us or the holders of the notes. As of June 30, 2026, our subsidiaries had no outstanding indebtedness. In connection with the completion of the Twin Eagle Acquisition, the Twin Eagle Credit Facility will remain outstanding as an obligation of the TERM Subsidiaries. Neither Expand nor its subsidiaries (other than the TERM Subsidiaries) are expected to provide guarantees of such facility. As of June 30, 2026, the Twin Eagle Credit Facility had $95 million of borrowings outstanding, $282 million of undrawn letters of credit outstanding and $623 million available for borrowing. The Twin Eagle Credit Facility matures in May 2027.

Our substantial indebtedness could adversely affect our financial condition.

We currently have, and after the completion of this offering, we will continue to have, a significant amount of indebtedness. This significant amount of indebtedness could limit our ability to obtain additional financing for working capital, capital expenditures, stock repurchases, acquisitions, debt service requirements or other purposes. It may also increase our vulnerability to adverse economic, market and industry conditions, limit our flexibility in planning for, or reacting to, changes in our business operations or to our industry overall, and place us at a disadvantage in relation to our competitors that have lower debt levels. Any or all of the above events and/or factors could have an adverse effect on our results of operations and financial condition.

We and our subsidiaries may still be able to incur substantially more debt.

The Company and its subsidiaries may be able to incur substantial additional indebtedness in the future. The notes and the indenture under which the notes will be issued do not restrict the Company’s or its subsidiaries’ ability to incur a specified amount of secured indebtedness or an unlimited amount of secured indebtedness to the extent the notes are secured equally and ratably with such indebtedness. In addition, the notes will not require us to achieve or maintain any minimum financial results relating to our financial condition or results of operations. Our ability to recapitalize, incur additional debt, and to take a

S-10

TABLE OF CONTENTS

number of other actions that are not limited by the terms of the notes could have the effect of diminishing our ability to make payments on the notes when due. In addition, the Company will not be restricted from repurchasing common stock by the terms of the notes.

We may issue additional notes.

We may from time to time without notice to, or the consent of, the holders of the notes, create and issue additional notes, which notes will be equal in rank to the notes offered hereby so that the new notes may be consolidated and form a single series with the notes offered hereby and have the same terms as to status, redemption or otherwise as such notes (except for the issue date and, under certain circumstances, the issue price, the initial interest payment date and corresponding record date and the date from which interest thereon will begin to accrue).

The notes will not be protected by restrictive covenants.

Except for limitations on liens, the notes and the indenture under which the notes will be issued do not contain any financial or operating covenants or restrictions on the payment of dividends, the incurrence of indebtedness or the issuance or repurchase of securities by the Company or any of its subsidiaries. In addition, the indenture does not contain covenants or other provisions to afford protection to holders of the notes in the event of a change of control involving us.

There is no public market for the notes.

We can give no assurances concerning the liquidity of any market that may develop for the notes offered hereby, the ability of any investor to sell the notes or the prices at which investors would be able to sell them. If a market for the notes does not develop, investors may be unable to resell the notes for an extended period of time, if at all. If a market for the notes does develop, it may not continue or it may not be sufficiently liquid to allow holders to resell any of the notes. Consequently, investors may not be able to liquidate their investment readily, and lenders may not readily accept the notes as collateral for loans.

An increase in market interest rates could result in a decrease in the market value of the notes.

The condition of the financial markets and prevailing interest rates have fluctuated in the past and are likely to continue fluctuating into the future, which could have an adverse effect on the market price of the notes. In general, as market interest rates rise, debt securities bearing interest at fixed rates of interest decline in value. Consequently, if you purchase notes bearing interest at fixed rates of interest and market interest rates increase, the market value of those notes may decline. We cannot predict the future level of market interest rates.

We may redeem the notes before they mature, which could occur when prevailing interest rates are relatively low.

We may redeem all or any portion of the notes at our option as described under “Description of the Notes — Optional Redemption.” Any such redemption may occur when prevailing interest rates are lower than the rates borne by the notes. These redemption rights may, depending on prevailing market conditions at the time, create reinvestment risk for the holders in that they may be unable to find a suitable replacement investment with a comparable return to those notes. If prevailing rates are lower at the time of redemption, holders may not be able to reinvest the redemption proceeds in a comparable security at an effective interest rate as high as the interest rate on the notes being redeemed. The redemption of the notes also may adversely affect holders’ ability to sell the notes if and at any time after the notes are called for partial or full redemption.

Our credit ratings may not reflect all risks of an investment in the notes, and changes in our credit ratings may adversely affect your investment in the notes and may require us to post cash collateral or additional letters of credit.

The credit ratings assigned to the notes are not a recommendation to buy, sell or hold the notes and do not address all material risks relating to an investment in the notes, but rather reflect only the view of each

S-11

TABLE OF CONTENTS

rating agency at the time the rating is issued. Each agency’s rating should be evaluated independently of any other agency’s rating. We have no obligation to maintain the ratings, and neither we nor any underwriter undertakes any obligation to advise holders of notes of any change in ratings.

We cannot assure you that our credit ratings will remain in effect for any given period of time or that a rating will not be revised downward, placed on a watch list or withdrawn entirely by the applicable rating agencies if in their judgment circumstances so warrant. An increase in the level of our outstanding indebtedness, an inability to reduce our indebtedness in a timely fashion or at all, or other events that could have an adverse impact on our business, properties, financial condition, results of operations or prospects may cause the rating agencies to downgrade our debt credit rating generally and the ratings on the notes. 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 trading price for or liquidity of the notes, increase our corporate borrowing costs, limit our access to the capital markets or result in more restrictive covenants in future debt agreements.

In addition, downgrades in our credit ratings would allow certain counterparties to our pipeline and gathering agreements and hedging contracts to require us to post cash collateral or letters of credit to support our commitments to them. Although we believe we have sufficient letter of credit capacity or other liquidity options to satisfy our collateral obligations in such a scenario, we cannot predict the impact these posting requirements may have on our business, financial condition, results of operations or prospects.

Our financial performance and other factors could adversely impact our ability to make payments on the notes.

Our ability to make scheduled payments with respect to our indebtedness, including the notes, will depend on our financial and operating performance, which, in turn, is subject to prevailing economic conditions and to financial, business and other factors beyond our control.

Risks Related to our Operations

The Twin Eagle Acquisition will materially expand our natural gas marketing and trading activities, which may expose us to increased commodity-price, liquidity and counterparty-credit risks.

Following the completion of the Twin Eagle Acquisition, we anticipate meaningfully expanding our natural gas marketing and trading activities, which will expose us to risks that differ from, and may be greater than, those associated with our historical operations.

Commodity-price volatility and changes in market conditions could result in mark-to-market losses on forward purchase and sale commitments and other trading positions. In addition, we or our counterparties may be required to post cash, letters of credit or other collateral under trading or similar arrangements. During periods of heightened commodity-price volatility, such requirements may increase significantly and on short notice, adversely affecting our liquidity and financial flexibility.

The acquisition will also increase the number and diversity of commercial counterparties with which we transact and our aggregate credit exposure through marketing and trading arrangements. Counterparties may fail to perform due to financial distress, bankruptcy, commodity-price volatility or other factors outside of our control. Although we expect to monitor counterparty creditworthiness and use credit-support arrangements where appropriate, those measures may not fully mitigate the risk of counterparty defaults or concentrations of credit exposure, which could adversely affect our results of operations, cash flows and financial condition.

TABLE OF CONTENTS

DESCRIPTION OF THE NOTES

The Company will issue the notes (as defined below) under a supplemental indenture (the “Supplemental Indenture”), to be dated as of the Issue Date, among itself and Regions Bank, as trustee (the “Trustee”), supplementing that certain Indenture, dated as of December 2, 2024 (the “Base Indenture” and, together with the Supplemental Indenture, the “Indenture”), between the Company and the Trustee. The terms of the notes include those expressly set forth in the Indenture and those made part of the Indenture by reference to the Trust Indenture Act of 1939, as amended (the “Trust Indenture Act”). The notes will be a new series of our debt securities described in the Base Prospectus. The notes issued in this offering will be limited to $ in aggregate principal amount of senior notes due 2031 (the “notes”), although we may issue an unlimited principal amount of additional notes of any series having identical terms and conditions as the notes of such series, other than issue date, issue price, the first interest payment date and the date from which interest shall accrue (“Additional Notes”). Any Additional Notes will be part of the same series as the notes that we are currently offering and will vote on all matters with the holders of such notes. We may from time to time issue other series of debt securities under the Base Indenture, in unlimited principal amount.

This Description of the Notes is intended to be a useful overview of the material provisions of the notes and the Indenture. This Description of the Notes is only a summary. You should also refer to the section entitled “Description of Debt Securities” in the Base Prospectus for a summary description of other material terms of the notes and the Base Indenture. To the extent that any terms of the notes set forth in this Description of the Notes are different than the terms described in the Base Prospectus, the terms in this Description of the Notes will govern. For more information, we refer you to the notes, the Supplemental Indenture and the Base Indenture filed, or incorporated by reference, as exhibits to the registration statement, which includes this prospectus supplement, or available by request.

You will find the definitions of certain capitalized terms used in this Description of the Notes under the heading “— Certain Definitions.” For purposes of this Description of the Notes, references to “the Company,” “we,” “our” and “us” refer only to Expand Energy Corporation and not to its subsidiaries. Certain defined terms used in this Description of the Notes but not defined herein have the meanings assigned to them in the Indenture.

Principal, Maturity and Interest

The notes will be issued in an initial maximum aggregate principal amount of $ , will bear interest at a rate of % per year and will mature on , 2031.

Interest on the notes will accrue from , 2026, and will be payable in cash semi-annually on and of each year, beginning , 2027. The notes will be issued in minimum denominations of $2,000 and integral multiples of $1,000 in excess of $2,000. We will make each interest payment on the notes to the holders of record on the or immediately preceding the related interest payment date (whether or not a business day). Interest will be computed on the basis of a 360-day year comprising twelve 30-day months.

Payments on the Notes; Paying Agent and Registrar

We will pay principal of, premium, if any, and interest on the notes at the office or agency designated by the Company, which is initially the corporate trust office of the trustee in Birmingham, Alabama. We will pay principal of, premium, if any, and interest on the notes in global form registered in the name of or held by The Depository Trust Company or its nominee in immediately available funds to The Depository Trust Company or its nominee, as the case may be, as the registered holder of such Global Note (as defined herein). The Company shall make all payments in respect of a Certificated Note (as defined herein) by mailing a check to the registered address of each holder thereof as such address shall appear in the Registrar’s books; provided, however, that payments on the notes represented by Certificated Notes may also be made by wire transfer to a U.S. dollar account maintained by the payee with a bank in the United States if such holder elects payment by wire transfer by giving written notice to the Trustee or the Paying Agent in accordance with the terms of the Indenture.

We have initially designated the Trustee to act as our Paying Agent and Registrar with respect to any Global Notes. We may, however, appoint and change the Paying Agent or Registrar without prior notice to the holders of the notes, and the Company or any of its Subsidiaries may act as Paying Agent or Registrar.

S-15

TABLE OF CONTENTS

If any scheduled date for a payment on the notes is not a business day, then the payment will be paid on the next succeeding business day without additional interest in respect of such delay.

Transfer and Exchange

A holder may transfer or exchange the notes in accordance with the Indenture. The Registrar and the Trustee may require a holder, among other things, to furnish appropriate endorsements and transfer documents. No service charge will be imposed by the Company, the Trustee or the Registrar for any registration of transfer or exchange of notes, but the Company may require a holder to pay a sum sufficient to cover any transfer tax or other governmental taxes and fees required by law or permitted by the Indenture. The Company is not required to transfer or exchange any note selected for redemption or any note for a period of 15 days before a selection of the notes to be redeemed.

The registered holder of a note will be treated as the owner of it for all purposes.

Optional Redemption

Prior to the Par Call Date, the Company may redeem the notes at its option, in whole or in part, at any time and from time to time, at a redemption price (expressed as a percentage of principal amount and rounded to three decimal places) equal to the greater of:

(1) (a) the sum of the present values of the remaining scheduled payments of principal and interest on the notes of such series to be redeemed discounted to the redemption date (assuming the notes of such series matured on such Par Call Date) on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Rate plus basis points less (b) interest accrued to the date of redemption; and

(2) 100% of the principal amount of the notes to be redeemed,

plus, in either case, accrued and unpaid interest thereon to but not including the redemption date.

On or after the Par Call Date, the Company may redeem the notes, in whole or in part, at any time and from time to time, at a redemption price equal to 100% of the principal amount of the notes being redeemed plus accrued and unpaid interest thereon to but not including the redemption date.

The Company’s actions and determinations in determining the redemption price shall be conclusive and binding for all purposes, absent manifest error.

For purposes of this Description of the Notes, “Par Call Date” shall mean , 2031.

Notice of any redemption will be mailed or electronically delivered (or otherwise transmitted in accordance with the Depositary’s applicable procedures) at least 10 days but not more than 60 days before the redemption date to each holder of notes to be redeemed.

Notwithstanding anything herein to the contrary, notices may be sent more than 60 days prior to a redemption date if the notice is issued in connection with a covenant defeasance or legal defeasance with respect to the notes or a satisfaction and discharge of the Indenture with respect to the notes or in accordance with the following paragraph.

Notice of any redemption may, at the Company’s discretion, be subject to one or more conditions precedent. If any such condition precedent has not been satisfied or waived, the Company shall provide written notice to the Trustee prior to the close of business one business day prior to the Redemption Date (or such shorter period as may be acceptable to the Trustee). Upon receipt of such notice, notwithstanding anything herein to the contrary, the notice of redemption shall be rescinded or delayed, and the redemption of the notes shall be rescinded or delayed as provided in such notice. Upon receipt, the Trustee shall provide such notice to each holder in the same manner in which the notice of redemption was given. A notice of redemption need not set forth the exact redemption price but only the manner of calculation thereof.

In the case of a partial redemption, selection of the notes of a series for redemption will be made pro rata, by lot or by such other method as the Trustee in its sole discretion deems appropriate and fair, subject to the

S-16

TABLE OF CONTENTS

last sentence of this paragraph. No notes of a principal amount of $2,000 or less will be redeemed in part. If the notes are to be redeemed in part only, the notice of redemption that relates to the notes will state the portion of the principal amount of the notes to be redeemed. A new note in a principal amount equal to the unredeemed portion of the note will be issued in the name of the holder of the note upon surrender for cancellation of the original note. For so long as the notes are held by the Depositary, the redemption of the notes shall be done in accordance with the policies and procedures of such Depositary.

Unless the Company defaults in payment of the redemption price or any conditions precedent described in the notice of redemption are not satisfied or waived and the notice of redemption is rescinded in accordance with the seventh paragraph under the heading “Optional Redemption,” on and after the redemption date interest will cease to accrue on the notes or portions thereof called for redemption.

“Treasury Rate” means, with respect to any redemption date for the notes, the yield will be determined by the Company in accordance with the following two paragraphs.

The Treasury Rate shall be determined by the Company after 4:15 p.m., New York City time (or after such time as yields on U.S. government securities are posted daily by the Board of Governors of the Federal Reserve System), on the third business day preceding the date of the notice of redemption relating to such redemption date based upon the yield or yields for the most recent day that appear after such time on such day in the most recent statistical release published by the Board of Governors of the Federal Reserve System designated as “Selected Interest Rates (Daily) — H.15” (or any successor designation or publication) (“H.15”) under the caption “U.S. government securities — Treasury constant maturities — Nominal” (or any successor caption or heading) (“H.15 TCM”). In determining the Treasury Rate, the Company shall select, as applicable: (1) the yield for the Treasury constant maturity on H.15 exactly equal to the period from the redemption date to the Par Call Date (the “Remaining Life”); or (2) if there is no such Treasury constant maturity on H.15 exactly equal to the Remaining Life, the two yields-one yield corresponding to the Treasury constant maturity on H.15 immediately shorter than and one yield corresponding to the Treasury constant maturity on H.15 immediately longer than the Remaining Life and shall interpolate to the Par Call Date on a straight-line basis (using the actual number of days) using such yields and rounding the result to three decimal places; or (3) if there is no such Treasury constant maturity on H.15 shorter than or longer than the Remaining Life, the yield for the single Treasury constant maturity on H.15 closest to the Remaining Life. For purposes of this paragraph, the applicable Treasury constant maturity or maturities on H.15 shall be deemed to have a maturity date equal to the relevant number of months or years, as applicable, of such Treasury constant maturity from the redemption date.

If on the third business day preceding the date of the notice of redemption relating to such redemption date H.15 TCM is no longer published, the Company shall calculate the Treasury Rate based on the rate per annum equal to the semi-annual equivalent yield to maturity at 11:00 a.m., New York City time, on the second business day preceding the date of such notice of redemption of the United States Treasury security maturing on, or with a maturity that is closest to, the Par Call Date, as applicable. If there is no United States Treasury security maturing on the Par Call Date but there are two or more United States Treasury securities with a maturity date equally distant from the Par Call Date, one with a maturity date preceding the Par Call Date and one with a maturity date following the Par Call Date, the Company shall select the United States Treasury security with a maturity date preceding the Par Call Date. If there are two or more United States Treasury securities maturing on the Par Call Date or two or more United States Treasury securities meeting the criteria of the preceding sentence, the Company shall select from among these two or more United States Treasury securities the United States Treasury security that is trading closest to par based upon the average of the bid and asked prices for such United States Treasury securities at 11:00 a.m., New York City time. In determining the applicable Treasury Rate in accordance with the terms of this paragraph, the semi-annual yield to maturity of the applicable United States Treasury security shall be based upon the average of the bid and asked prices (expressed as a percentage of principal amount) at 11:00 a.m., New York City time, of such United States Treasury security, and rounded to three decimal places.

The Company is not required to make mandatory redemption payments or sinking fund payments with respect to the notes. Accordingly, Article XI of the Base Indenture shall not apply to the notes.

The Company and its subsidiaries and affiliates may acquire the notes by means other than a redemption, whether by tender offer, open market purchases, negotiated transactions or otherwise, in accordance with applicable securities laws.

TABLE OF CONTENTS

Ranking

The notes will be our senior unsecured obligations and will (i) rank equally in right of payment with all of the Company’s existing and future senior indebtedness (including the obligations under the Existing Credit Facility and the Existing Notes), (ii) rank senior in right of payment to any of the Company’s future indebtedness that is expressly subordinated in right of payment to the notes, (iii) be effectively subordinated to any of our existing and future secured indebtedness, if any, to the extent of the value of the collateral securing such indebtedness and (iv) be structurally subordinated to all of the existing and future indebtedness and other liabilities (including trade payables) of each of our Subsidiaries, including the Twin Eagle Credit Facility. In the event of bankruptcy, liquidation, reorganization or other winding up of the Company upon a default in payment with respect to, or the acceleration of, any senior secured indebtedness, the assets of the Company that secure such senior secured indebtedness will be available to pay obligations on the notes only after all obligations under such senior secured indebtedness have been repaid in full from such assets. We advise you that there may not be sufficient assets remaining to pay amounts due on any or all the notes then outstanding.

As of June 30, 2026, we had no secured indebtedness for borrowed money and we had approximately $3,738 million in principal amount of unsecured indebtedness for borrowed money, including zero outstanding under our revolving credit facility and $3,738 million principal amount of senior notes, none of which was guaranteed by our subsidiaries.

The TERM Subsidiaries are party to the Twin Eagle Credit Facility, which we intend to assume upon closing of the Twin Eagle Acquisition and subsequently terminate once borrowings and outstanding letters of credit under such facility are canceled. In May 2025, the Twin Eagle Credit Facility was renewed with a maximum capacity of $1.40 billion, an incremental accordion capacity of $0.6 billion and a maturity in May 2027. At June 30, 2026, Twin Eagle and each of the TERM Subsidiaries was in compliance with its borrowing base and all covenants, which include requirements related to working capital, tangible net worth, and leverage ratios.

The Twin Eagle Credit Facility may be utilized for borrowings or for the issuance of letters of credit. Borrowings under the Twin Eagle Credit Facility bear interest at a rate based on either secured overnight financing rate, a base rate or a quoted cost-of-funds rate, in each case plus an applicable margin. Additionally, Twin Eagle is required to pay a quarterly commitment fee on the unused committed portion of the Twin Eagle Credit Facility (up to $0.7 billion), an annual facility fee, and fees related to letters of credit. Substantially, all of TERM’s assets are pledged as security for the Twin Eagle Credit Facility. As of June 30, 2026, the Twin Eagle Credit Facility had $95 million of borrowings outstanding, $282 million of undrawn letters of credit outstanding and $623 million available for borrowing. The Company anticipates borrowing needs under the Twin Eagle Credit Facility will be minimal upon closing of the Twin Eagle Acquisition and that the majority of letters of credit will be replaced by a parent guarantee from the Company, given the Company’s investment grade rating.

Certain Covenants

Limitation on Liens

The Company will not, and will not permit any of its Restricted Subsidiaries to, create, Incur or assume, any Lien securing Funded Debt (other than Permitted Liens) upon any Principal Property, whether owned on the Issue Date or acquired after that date, unless the Indebtedness due under the Indenture (as it relates to the notes), the notes are secured equally and ratably with (or senior in priority to in the case of Liens with respect to Funded Debt that is expressly subordinated to the notes) the Funded Debt secured by such Lien for so long as such Funded Debt is so secured.

Notwithstanding the preceding paragraph, we may, and may permit any Restricted Subsidiary of ours to, create, Incur or assume, any Lien securing Funded Debt upon any Principal Property without securing the Indebtedness due under the Indenture, and the notes if the aggregate principal amount of such Funded Debt secured by such Lien upon such Principal Property, together with the aggregate outstanding principal amount of all other Funded Debt of ours and of any Restricted Subsidiary of ours secured by any Liens (other than Permitted Liens) upon Principal Property, does not at the time such Funded Debt is created,

S-18

TABLE OF CONTENTS

Incurred or assumed (or, if later, at the time such Lien is created, Incurred or assumed) exceed the greater of (i) 15% of Consolidated Net Tangible Assets at such time and (ii) $3.0 billion.

Reports

The Company will furnish or file with the Trustee, (i) within 15 days after it files the same with the SEC, copies of the annual reports and the information, documents and other reports (or copies of such portions of any of the foregoing as the SEC may by rules and regulations prescribe) that the Company is required to file with the SEC pursuant to Section 13 or 15(d) of the Exchange Act and (ii) other information, documents, or reports as may be required pursuant to the Trust Indenture Act at the times and in the manner provided in the Trust Indenture Act. For purposes of this covenant, the Company will be deemed to have furnished such reports and information to, or filed such reports and information with, the Trustee (and, if applicable, any other Persons) as required by this covenant if it has filed such reports or information with the SEC via the EDGAR filing system (or any successor filing system) or otherwise made such reports or information publicly available on a freely accessible page on the Company’s website. The Trustee shall have no obligation whatsoever to determine whether or not such reports and information have been filed or have been posted on such website.

The Company also shall furnish to the Trustee, within 120 days after the end of each fiscal year of the Company, a brief certificate from the principal executive officer, principal financial officer or principal accounting officer as to his or her knowledge of the Company’s compliance with all covenants under the Indenture.

Delivery of any reports, information and documents under this caption “— Reports” to the Trustee is for informational purposes only and the Trustee’s receipt of such shall not constitute notice, constructive or otherwise, of any information contained therein or determinable from information contained therein, including the compliance by the Company with any of the Company’s covenants (as to which the Trustee is entitled to rely exclusively on certificates described in the second paragraph under this caption “— Reports”).

Unrestricted Subsidiaries

The Board of Directors of the Company may after the Issue Date designate any Subsidiary as an “Unrestricted Subsidiary” if: (1) no Default or Event of Default shall have occurred and be continuing at the time of or after giving effect to such designation; and (2) such Subsidiary has no Indebtedness other than Non-Recourse Debt.

The Board of Directors of the Company may at any time, subject to the following sentence, designate any Unrestricted Subsidiary to be a Restricted Subsidiary of the Company. Any such designation will be deemed to be an incurrence of Funded Debt and Liens by a Restricted Subsidiary of the Company of any outstanding Funded Debt and Liens, respectively, of such Unrestricted Subsidiary, and such designation will only be permitted if no Default or Event of Default would be in existence following such designation.

Events of Default

Each of the following is an Event of Default with respect to the notes:

(1) default in any payment of interest on any note of such series when due and payable, continued for 30 days;

(2) default in the payment of principal of or premium, if any, on any note of such series when due and payable, whether at its Stated Maturity or upon redemption, acceleration or otherwise;

(3)(a) failure by the Company to comply, for 180 days after notice as provided below, with the covenant described under “— Certain Covenants — Reports;” or

(b) failure by the Company to comply, for 90 days after notice as provided below, with its agreements (other than the agreements that are the subject of clauses (1) – (2) and (3)(a) above) contained in the Indenture (as it relates to the notes of such series) or the notes;

S-19

TABLE OF CONTENTS

(4) default under any mortgage, indenture or similar instrument under which there is issued or by which there is secured or evidenced any Indebtedness for money borrowed by the Company (or the payment of which is guaranteed by the Company), other than Indebtedness owed to a Subsidiary, whether such Indebtedness or guarantee now exists or is created after the Issue Date, which default:

(a) is caused by a failure to pay principal of, or interest or premium, if any, on such Indebtedness prior to the expiration of the grace period provided in such Indebtedness (“payment default”); or

(b) results in the acceleration of such Indebtedness prior to its maturity; and, in each case, the principal amount of any such Indebtedness, together with the principal amount of any other such Indebtedness under which there is an outstanding uncured payment default or the maturity of which has been and remains so accelerated, as applicable, aggregates to $250.0 million or more; or

(5) certain events of bankruptcy, insolvency or reorganization of the Company (the “bankruptcy provisions”).

However, a Default under clause (3) above will not constitute an Event of Default until the Trustee or the holders of at least 25% in principal amount of the then outstanding notes notify the Company in writing of the Default and the Company does not cure such Default within the applicable time specified in clause (3) above after receipt of such notice. Such notice must specify the Default, demand that it be remedied, and state that such notice is a “Notice of Default.”

If an Event of Default (other than an Event of Default described in clause (5) above) occurs and is continuing, the Trustee by written notice to the Company, or holders of at least 25% in principal amount of the then outstanding notes by written notice to the Company and the Trustee, may, and the Trustee at the request of holders of at least 25% in principal amount of the then outstanding notes shall, declare the principal, premium, if any, and accrued and unpaid interest, if any, on all the notes to be due and payable. Such notice must specify the Event of Default and state that such notice is a “Notice of Acceleration.” Upon such a declaration, such principal, premium, if any, and accrued and unpaid interest in respect of the notes will be due and payable immediately.

In the event of a declaration of acceleration of the notes because an Event of Default described in clause (4) above has occurred and is continuing, the declaration of acceleration of the notes shall be automatically annulled if (x) such Indebtedness or guarantee is discharged in full (other than customary surviving contingent obligations) or (y) the Default triggering such Event of Default pursuant to clause (4) shall be remedied or cured by the Company or waived by the holders of the relevant Indebtedness, in each case within 60 days after the written notice of declaration of acceleration of the notes with respect thereto is received by the Company and if the annulment of the acceleration of the notes would not conflict with any judgment or decree of a court of competent jurisdiction.

If an Event of Default described in clause (5) above occurs, the principal, premium, if any, and accrued and unpaid interest on all the notes will become and be immediately due and payable without any declaration or other act on the part of the Trustee or any holders.

At any time after a declaration of acceleration, but before a judgment or decree for the payment of the money due has been obtained by the Trustee, holders of a majority in principal amount of the outstanding notes may by notice to the Trustee and the Company (including, without limitation, waivers and consents obtained in connection with a purchase of, or tender offer or exchange offer for, notes) waive all current defaults (except with respect to nonpayment of principal, premium, if any, or interest) and rescind any such acceleration with respect to the notes and its consequences if rescission would not conflict with any judgment or decree of a court of competent jurisdiction.

Certain provisions relating to the rights and remedies of holders of notes and the rights, remedies and obligations of the Trustee are described in the Description of Debt Securities set forth in the Base Prospectus under the caption “— Events of Default.”

Amendments and Waivers

(in each case, as it relates to the notes) and the notes with the consent of the holders of a majority in principal amount of the notes then outstanding (including, without limitation, consents obtained in connection with a purchase of, or tender offer or exchange offer for, notes) and any past default or compliance with any provisions of the Supplemental Indenture and the Base Indenture and the notes may be waived with the consent of the holders of a majority in principal amount of the notes then outstanding (including, without limitation, consents obtained in connection with a purchase of, or tender offer or exchange offer for, notes).

However, without the consent of each holder of an outstanding note, no amendment, supplement or waiver may (with respect to any notes held by a non-consenting holder):

(1) reduce the principal amount of notes whose holders must consent to an amendment, supplement or waiver;

(2) reduce the stated rate of interest or extend the stated time for payment of interest on any note;

(3) reduce the principal of or extend the Stated Maturity of any note;

(4) waive a Default or Event of Default in the payment of principal of, premium, if any, or interest on the notes (except a rescission of acceleration of the notes by holders of a majority in aggregate principal amount of the then outstanding notes with respect to a nonpayment default and a waiver of the payment default that resulted from such acceleration);

(5) reduce the premium payable upon the redemption of any note or change the time at which any note of such series may be redeemed as described above under “— Optional Redemption” whether through an amendment or waiver of provisions in the Indenture, related definitions or otherwise;

(6) make any note payable in money other than that stated in the note;

(7) impair the right of any holder to receive payment of principal, premium, if any, and interest on such holder’s notes on or after the due dates therefor or to institute suit for the enforcement of any payment on or with respect to such holder’s notes; or

(8) make any change in the amendment or waiver provisions that require each holder’s consent.

Notwithstanding the foregoing, without the consent of any holder of notes, the Company and the Trustee may amend or supplement the Supplemental Indenture and the Base Indenture and the notes to:

(1) cure any ambiguity, omission, defect or inconsistency;

(2) provide for the assumption by a successor entity of the obligations of the Company under the Supplemental Indenture and the Base Indenture or the notes;

(3) provide for or facilitate the issuance of uncertificated notes of such series in addition to or in place of certificated notes (provided that the uncertificated notes are issued in registered form for purposes of Section 163(f) of the Code);

(4) add Guarantees with respect to the notes of such series, evidence the release of a Guarantor from its Guarantee or provide for the assumption by a successor entity of the obligations of a Guarantor in accordance with the applicable provisions of the Indenture;

(5) secure the notes;

(6) add covenants of the Company or other obligor under the Indenture or the notes, as the case may be or Events of Default for the benefit of the holders of the notes or to make other changes that would provide additional rights to the holders of the notes or to surrender any right or power conferred upon the Company or other such obligor;

(7) make any change that does not adversely affect the legal or contractual rights of any holder under the Indenture (as it relates to the notes of such series) or the notes;

S-21

(8) evidence and provide for the acceptance of an appointment under the Indenture of a successor trustee; provided that the successor trustee is otherwise qualified and eligible to act as such under the terms of the Indenture;

(9) provide for the issuance of Additional Notes of such series permitted to be issued under the Indenture (as it relates to the notes of such series);

(10) comply with the rules of any applicable securities depositary; or

(11) conform the text of the Supplemental Indenture or the Base Indenture, the notes to any provision of this “Description of the Notes” or the “Description of Debt Securities” set forth in the Base Prospectus to the extent that such provision in this “Description of the Notes” or such “Description of Debt Securities” was intended to be a complete description or summary of a provision of the Indenture or the notes.

The consent of the holders is not necessary under the Indenture to approve the particular form of any proposed amendment, supplement or waiver. It is sufficient if such consent approves the substance of the proposed amendment, supplement or waiver. A consent to any amendment, supplement or waiver under the Indenture by any holder of notes given in connection with a tender of such holder’s notes will not be rendered invalid by such tender. After an amendment, supplement or waiver under the Indenture becomes effective, the Company is required to send to the applicable holders a notice briefly describing such amendment, supplement or waiver. However, the failure to give such notice to all the holders of the notes, or any defect in the notice, will not impair or affect the validity of any amendment, supplement or waiver.

Defeasance

The legal defeasance and covenant defeasance provisions described under “Description of Debt Securities — Defeasance of Debt Securities and Certain Covenants in Certain Circumstances” in the Base Prospectus shall be applicable to the notes and any Guarantee thereof. In the case of a covenant defeasance, the Company may terminate its obligations to comply with the covenant described under “— Certain Covenants — Limitation on Liens” above in this Description of the Notes and certain covenants described under “— Certain Covenants” in the Description of Debt Securities in the Base Prospectus, other than the covenant described under clause (2) under “— Consolidation, Merger and Sale of Assets.”

If the Company exercises its legal defeasance or its covenant defeasance option in respect of the notes, all Guarantees in respect of the notes (if any are in effect at such time) will terminate.

Satisfaction and Discharge

The satisfaction and discharge provisions described under “Description of Debt Securities — Satisfaction and Discharge” in the Base Prospectus shall be applicable to the notes and any Guarantee thereof.

MATERIAL U.S. FEDERAL INCOME TAX CONSEQUENCES

The following discussion is a summary of the material U.S. federal income tax consequences of the purchase, ownership and disposition of the notes issued pursuant to this offering but does not purport to be a complete analysis of all potential tax effects. The effects of other U.S. federal tax laws, such as estate and gift tax laws, and any applicable state, local or foreign tax laws are not discussed. This discussion is based on the U.S. Internal Revenue Code of 1986, as amended (the “Code”), Treasury regulations promulgated thereunder (“Treasury Regulations”), judicial decisions, and published rulings and administrative pronouncements of the U.S. Internal Revenue Service (the “IRS”), in each case, in effect as of the date hereof. These authorities may change or be subject to differing interpretations. Any such change or differing interpretation may be applied retroactively in a manner that could adversely affect a holder of the notes. We have not sought and will not seek any rulings from the IRS regarding the matters discussed below. There can be no assurance that the IRS or a court will not take a contrary position to that discussed below regarding the tax consequences of the purchase, ownership and disposition of the notes.

This discussion is limited to holders who hold the notes as “capital assets” within the meaning of Section 1221 of the Code (generally, property held for investment). In addition, this discussion is limited to persons purchasing the notes for cash at original issue and at their original “issue price” within the meaning of Section 1273 of the Code (i.e., the first price at which a substantial amount of the notes is sold to the public for cash other than to bond houses, brokers or similar persons or organizations acting in the capacity of underwriters, placement agents or wholesalers). This discussion assumes that the notes are not issued with original issue discount as that term is defined in the Code and the Treasury Regulations. This discussion does not address all U.S. federal income tax consequences relevant to a holder’s particular circumstances, including the impact of the Medicare contribution tax on net investment income under Section 1411 of the Code. In addition, it does not address consequences relevant to holders subject to special rules, including, without limitation:

•

U.S. expatriates and former citizens or long-term residents of the United States;

•

persons subject to the alternative minimum tax;

•

U.S. Holders (as defined below) whose functional currency is not the U.S. dollar;

•

persons holding the notes as part of a hedge, straddle or other risk reduction strategy or as part of a conversion transaction or other integrated investment;

•

banks, insurance companies, and other financial institutions;

•

real estate investment trusts, regulated investment companies or grantor trusts;

•

brokers, dealers or traders in securities, currencies or commodities;

•

“controlled foreign corporations,” “passive foreign investment companies,” and corporations that accumulate earnings to avoid U.S. federal income tax;

•

S corporations, partnerships or other entities or arrangements treated as partnerships for U.S. federal income tax purposes (and investors therein);

•

tax-exempt organizations or governmental organizations;

•

persons deemed to sell the notes under the constructive sale provisions of the Code;

•

individual retirement accounts or other tax-deferred accounts;

•

U.S. Holders that hold the notes through non-U.S. brokers or other non-U.S. intermediaries;

•

entities subject to the U.S. anti-inversion rules;

•

holders that are members of an “expanded group” or “modified expanded group” with us within the meaning of the Treasury Regulations under Section 385 of the Code;

•

hybrid entities;

•

holders that have made an election to include in gross income all interest on a note under the constant yield method;

S-28

TABLE OF CONTENTS

•

persons subject to the base erosion and anti-abuse tax;

•

non-U.S. trusts or estates that have United States beneficiaries;

•

persons subject to the personal holding company rules; and

•

persons subject to special tax accounting rules as a result of any item of gross income with respect to the notes being taken into account in an applicable financial statement.

If an entity or arrangement treated as a partnership for U.S. federal income tax purposes holds the notes, the tax treatment of a partner in the partnership will depend on the status of the partner, the activities of the partnership and certain determinations made at the partner level. Accordingly, partnerships holding the notes and the partners in such partnerships should consult their tax advisors regarding the U.S. federal income tax consequences to them.

THIS DISCUSSION IS FOR INFORMATIONAL PURPOSES ONLY AND IS NOT TAX ADVICE. INVESTORS SHOULD CONSULT THEIR TAX ADVISORS WITH RESPECT TO THE APPLICATION OF THE U.S. FEDERAL INCOME TAX LAWS TO THEIR PARTICULAR SITUATIONS AS WELL AS ANY TAX CONSEQUENCES OF THE PURCHASE, OWNERSHIP AND DISPOSITION OF THE NOTES ARISING UNDER OTHER U.S. FEDERAL TAX LAWS (INCLUDING ESTATE AND GIFT TAX LAWS), UNDER THE LAWS OF ANY STATE, LOCAL OR NON-U.S. TAXING JURISDICTION OR UNDER ANY APPLICABLE TAX TREATY, INCLUDING THE CONSEQUENCES OF ANY PROPOSED CHANGE IN APPLICABLE LAWS.

Characterization of the Notes

In certain circumstances, as described under “Description of the Notes — Optional Redemption” we may be obligated to pay amounts on the notes that are in excess of stated interest and principal payments on the notes.

Although the issue is not free from doubt, we believe and intend to take the position that the possibility of paying such additional amounts should not cause the notes to be treated as contingent payment debt instruments, which are subject to special rules. This position is based in part on our determination that, as of the issuance date of the notes, the possibility that such additional amounts will have to be paid is a remote or incidental contingency within the meaning of applicable Treasury Regulations.

Our determination that the notes are not contingent payment debt instruments is binding on a holder, unless such holder explicitly discloses to the IRS on its tax return for the year during which it acquires the notes that it is taking a different position. However, our position is not binding on the IRS. If the IRS takes a contrary position to that described above, then the notes may be treated as contingent payment debt instruments and, regardless of a holder’s method of accounting, a holder may be required to accrue interest income on the notes based upon a comparable yield at which we would have issued a fixed rate debt instrument with no contingent payments, but with terms and conditions similar to those of the notes. In addition, any gain on the sale, exchange, redemption, retirement or other taxable disposition of the notes generally would be characterized as ordinary income, rather than capital gain. The remainder of this discussion assumes that the notes will not be treated as contingent payment debt instruments. Holders should consult their own tax advisors regarding the possible application of the contingent payment debt instrument rules to the notes.

Tax Consequences Applicable to U.S. Holders

Definition of a U.S. Holder

For purposes of this discussion, a “U.S. Holder” is a beneficial owner of a note that, for U.S. federal income tax purposes, is or is treated as:

•

an individual who is a citizen or resident of the United States;

•

a corporation created or organized under the laws of the United States, any state thereof, or the District of Columbia;

S-29

TABLE OF CONTENTS

•

an estate, the income of which is subject to U.S. federal income tax regardless of its source; or

•

a trust that (1) is subject to the primary supervision of a U.S. court and the control of one or more “United States persons” (within the meaning of Section 7701(a)(30) of the Code), or (2) has a valid election in effect to be treated as a United States person for U.S. federal income tax purposes.

Payments of Interest

Interest on a note will be taxable to a U.S. Holder as ordinary income at the time such interest is received or accrued, in accordance with such U.S. Holder’s method of tax accounting for U.S. federal income tax purposes.

Sale or Other Taxable Disposition

A U.S. Holder will recognize gain or loss on the sale, exchange, redemption, retirement or other taxable disposition of a note. The amount of such gain or loss will equal the difference between the amount received for the note in cash or other property valued at fair market value (less amounts attributable to any accrued but unpaid interest, which will be taxable as interest to the extent not previously included in income) and the U.S. Holder’s adjusted tax basis in the note. A U.S. Holder’s adjusted tax basis in a note generally will be equal to the amount the U.S. Holder paid for the note, reduced by any payment previously received by the U.S. Holder on the note other than a payment of qualified stated interest. Any gain or loss will be capital gain or loss, and will be long-term capital gain or loss if the U.S. Holder has held the note for more than one year at the time of sale or other taxable disposition. Otherwise, such gain or loss will be short-term capital gain or loss. Long-term capital gains recognized by certain non-corporate U.S. Holders, including individuals, generally will be taxable at a reduced rate. The deductibility of capital losses is subject to limitations.

Information Reporting and Backup withholding

A U.S. Holder may be subject to information reporting and backup withholding when such holder receives payments on a note or receives proceeds from the sale or other taxable disposition of a note (including a redemption or retirement of a note). Certain U.S. Holders are exempt from backup withholding, including corporations and certain tax-exempt organizations. A U.S. Holder will be subject to backup withholding if such holder is not otherwise exempt and:

•

the holder fails to furnish the holder’s taxpayer identification number, which for an individual is ordinarily his or her social security number;

•

the holder furnishes an incorrect taxpayer identification number;

•

the applicable withholding agent is notified by the IRS that the holder previously failed to properly report payments of interest or dividends; or

•

the holder fails to certify under penalties of perjury on IRS Form W-9 (or applicable successor form) that the holder has furnished a correct taxpayer identification number and that the IRS has not notified the holder that the holder is subject to backup withholding.

The amount of any reportable payments, including reportable payments of interest, made to a U.S. Holder that is not exempt, and the amount of any tax withheld with respect to such payments, will be reported to such U.S. Holder and to the IRS for each calendar year.

Backup withholding is not an additional tax. Any amounts withheld under the backup withholding rules may be allowed as a refund or a credit against a U.S. Holder’s U.S. federal income tax liability, provided the required information is timely furnished to the IRS. U.S. Holders should consult their tax advisors regarding their qualification for an exemption from backup withholding and the procedures for obtaining such an exemption.

Tax Consequences Applicable to Non-U.S. Holders

Definition of a Non-U.S. Holder

For purposes of this discussion, a “Non-U.S. Holder” is a beneficial owner of a note that is neither a U.S. Holder nor an entity or arrangement treated as a partnership for U.S. federal income tax purposes.

TABLE OF CONTENTS

Payments of Interest

Interest paid on a note to a Non-U.S. Holder that is not effectively connected with the Non-U.S. Holder’s conduct of a trade or business within the United States generally will not be subject to U.S. federal income tax, or withholding tax of 30% (or such lower rate specified by an applicable income tax treaty), provided that:

•

the Non-U.S. Holder does not, actually or constructively, own 10% or more of the total combined voting power of all classes of our voting stock within the meaning of Section 871(h)(3) of the Code;

•

the Non-U.S. Holder is not a “controlled foreign corporation” described in Section 881(c)(3)(C) of the Code that is related to us, actually or constructively, through the stock ownership rules of Section 864(d)(4) of the Code;

•

the Non-U.S. Holder is not a bank that received the note on an extension of credit made pursuant to a loan agreement entered into in the ordinary course of its trade or business as described in Section 881(c)(3)(A) of the Code; and

•

either (1) the Non-U.S. Holder certifies in a statement provided to the applicable withholding agent under penalties of perjury that it is not a United States person and provides its name and address; (2) a securities clearing organization, bank or other financial institution that holds customers’ securities in the ordinary course of its trade or business and holds the note on behalf of the Non-U.S. Holder certifies to the applicable withholding agent under penalties of perjury that it, or the financial institution between it and the Non-U.S. Holder, has received from the Non-U.S. Holder a statement under penalties of perjury that such holder is not a United States person and provides a copy of such statement to the applicable withholding agent; or (3) the Non-U.S. Holder holds its note directly through a “qualified intermediary” (within the meaning of applicable Treasury Regulations) and certain conditions are satisfied, which a non-U.S. financial institution may establish by furnishing an IRS Form W-8IMY certifying that it has entered into an agreement with the IRS to be treated as a qualified intermediary.

If a Non-U.S. Holder does not satisfy the requirements above, such Non-U.S. Holder may be entitled to a reduction in or an exemption from withholding on such interest as a result of an applicable income tax treaty. To claim such entitlement, the Non-U.S. Holder must provide the applicable withholding agent with a properly executed IRS Form W-8BEN or W-8BEN-E (or other applicable documentation) claiming a reduction in or exemption from withholding tax under the benefit of an income tax treaty between the United States and the country in which the Non-U.S. Holder resides or is established. A Non-U.S. Holder claiming treaty benefits may also be required to furnish its U.S. taxpayer identification number, and a claim for exemption will not be effective if the applicable withholding agent has actual knowledge or reason to know that the statements on the form are false.

If interest paid to a Non-U.S. Holder is effectively connected with the Non-U.S. Holder’s conduct of a trade or business within the United States (and, if required by an applicable income tax treaty, the Non-U.S. Holder maintains a permanent establishment in the United States to which such interest is attributable), the Non-U.S. Holder will be exempt from the U.S. federal withholding tax described above. To claim the exemption, the Non-U.S. Holder must furnish to the applicable withholding agent a valid IRS Form W- 8ECI, certifying that interest paid on a note is not subject to withholding tax because it is effectively connected with the conduct by the Non-U.S. Holder of a trade or business within the United States.

Any such effectively connected interest will be subject to U.S. federal income tax at the regular graduated rates. A Non-U.S. Holder that is a corporation also may be subject to a branch profits tax at a rate of 30% (or such lower rate specified by an applicable income tax treaty) on such effectively connected interest, as adjusted for certain items.

The certifications described above must be provided to the applicable withholding agent prior to the payment of interest and must be updated periodically. Non-U.S. Holders that do not timely provide the applicable withholding agent with the required certification, but that qualify for a reduced rate under an applicable income tax treaty, may obtain a refund of any excess amounts withheld by timely filing an appropriate claim for refund with the IRS. Non-U.S. Holders should consult their tax advisors regarding their entitlement to benefits under any applicable income tax treaty.

TABLE OF CONTENTS

Sale or Other Taxable Disposition

A Non-U.S. Holder will not be subject to U.S. federal income tax on any gain realized upon the sale, exchange, redemption, retirement or other taxable disposition of a note (such amount excludes any amount allocable to accrued and unpaid interest, which will be treated as interest and may be subject to the rules discussed above in “— Payments of Interest”) unless:

•

the gain is effectively connected with the Non-U.S. Holder’s conduct of a trade or business within the United States (and, if required by an applicable income tax treaty, the Non-U.S. Holder maintains a permanent establishment in the United States to which such gain is attributable); or

•

the Non-U.S. Holder is a nonresident alien individual present in the United States for 183 days or more during the taxable year of the disposition and certain other requirements are met.

Gain described in the first bullet point above will be subject to U.S. federal income tax on a net income basis at the regular graduated rates. A Non-U.S. Holder that is a foreign corporation also may be subject to a branch profits tax at a rate of 30% (or such lower rate specified by an applicable income tax treaty) on such effectively connected gain, as adjusted for certain items.

Gain described in the second bullet point above will be subject to U.S. federal income tax at a rate of 30% (or such lower rate specified by an applicable income tax treaty), which may be offset by U.S. source capital losses of the Non-U.S. Holder (even though the individual is not considered a resident of the United States), provided the Non-U.S. Holder has timely filed U.S. federal income tax returns with respect to such losses.

A Non-U.S. Holder’s ability to claim a loss on the disposition of a note will be subject to substantial limitations. Non-U.S. Holders should consult their tax advisors regarding the tax consequences of disposing of the notes at a loss.

Non-U.S. Holders should consult their tax advisors regarding any applicable income tax treaties that may provide for different rules.

Information Reporting and Backup Withholding

Payments of interest will not be subject to backup withholding, provided the applicable withholding agent does not have actual knowledge or reason to know the holder is a United States person and the holder certifies its non-U.S. status as described above under “— Payments of Interest.” However, information returns are required to be filed with the IRS in connection with any interest paid to the Non-U.S. Holder, regardless of whether any tax was actually withheld. In addition, proceeds of the sale or other taxable disposition of a note (including a retirement or redemption of the note) within the United States or conducted through certain U.S.-related brokers generally will not be subject to backup withholding or information reporting, if the applicable withholding agent receives the statement described above and does not have actual knowledge or reason to know that such holder is a United States person or the holder otherwise establishes an exemption. Proceeds of a disposition of a note paid outside the United States and conducted through a non-U.S. office of a non-U.S. broker generally will not be subject to backup withholding or information reporting, unless the broker is (1) a United States person, (2) a controlled foreign corporation, (3) a foreign person 50% or more of whose gross income for certain periods is effectively connected with the conduct of a trade or business within the United States, or (4) a foreign partnership if, at any time during its taxable year, one or more of its partners are United States persons that in the aggregate hold more than 50% of the income or capital interests in the partnership, or the foreign partnership is engaged in a trade or business within the United States, and, in each case, the Non-U.S. Holder does not establish an exemption.

Copies of information returns that are filed with the IRS may also be made available under the provisions of an applicable treaty or agreement to the tax authorities of the country in which the Non-U.S. Holder resides or is established.

Backup withholding is not an additional tax. Any amounts withheld under the backup withholding rules may be allowed as a refund or a credit against a Non-U.S. Holder’s U.S. federal income tax liability, provided the required information is timely furnished to the IRS.

TABLE OF CONTENTS

Additional Withholding Tax on Payments Made to Foreign Accounts

Withholding taxes may be imposed under Sections 1471 to 1474 of the Code (such Sections commonly referred to as the Foreign Account Tax Compliance Act, or “FATCA”) on certain types of payments made to non-U.S. financial institutions and certain other non-U.S. entities. Specifically, a 30% withholding tax may be imposed on payments of interest on, or (subject to the proposed Treasury Regulations discussed below) gross proceeds from the sale or other disposition of, a note paid to a “foreign financial institution” or a “non-financial foreign entity” (each as defined in the Code), unless (1) the foreign financial institution undertakes certain diligence and reporting obligations, (2) the non-financial foreign entity either certifies it does not have any “substantial United States owners” (as defined in the Code) or furnishes identifying information regarding each substantial United States owner, or (3) the foreign financial institution or nonfinancial foreign entity otherwise qualifies for an exemption from these rules. If the payee is a foreign financial institution and is subject to the diligence and reporting requirements in (1) above, it must enter into an agreement with the U.S. Department of the Treasury requiring, among other things, that it undertake to identify accounts held by certain “specified United States persons” or “United States owned foreign entities” (each as defined in the Code), annually report certain information about such accounts, and withhold 30% on certain payments to non-compliant foreign financial institutions and certain other account holders. Foreign financial institutions located in jurisdictions that have an intergovernmental agreement with the United States governing FATCA may be subject to different rules.

Under the applicable Treasury Regulations and administrative guidance, withholding under FATCA generally applies to payments of interest on a note. While withholding under FATCA would have applied also to payments of gross proceeds from the sale or other disposition of a note on or after January 1, 2019, proposed Treasury Regulations eliminate FATCA withholding on payments of gross proceeds entirely. Taxpayers generally may rely on these proposed Treasury Regulations until final Treasury Regulations are issued, although there can be no assurance that a similar rule will not take effect in the future. In many cases, a Non-U.S. Holder may establish an exemption from, or compliance with, FATCA by providing a properly completed and duly executed IRS Form W-8BEN or W-8BEN-E (or other applicable successor form) to the applicable withholding agent, although additional information and diligence requirements may apply. We will not pay any additional amounts to holders in respect of any amounts withheld under FATCA.

Prospective investors should consult their tax advisors regarding the potential application of withholding under FATCA to their investment in the notes.

UNDERWRITING

Subject to the terms and conditions stated in the underwriting agreement dated the date of this prospectus supplement by and among us and the underwriters named below, for whom Citigroup Global Markets Inc. and J.P. Morgan Securities LLC are acting as representatives, we have agreed to sell to each of the underwriters, and each of the underwriters has agreed, severally and not jointly, to purchase from us, the principal amount of the notes indicated in the following table:

Underwriters	Principal Amount of the notes
Citigroup Global Markets Inc.		$
J.P. Morgan Securities LLC
Total		$

Under the terms and conditions of the underwriting agreement, if the underwriters take any of the notes, then they are obligated to take and pay for all the notes. The underwriting agreement also provides that if an underwriter defaults, the purchase commitments of non-defaulting underwriters may also be increased or the underwriting agreement may be terminated. The underwriters are offering the notes, subject to prior sale, when, as and if issued to and accepted by them, subject to approval of legal matters by their counsel, including the validity of the notes, and other conditions contained in the underwriting agreement, such as the receipt by the underwriters of officer’s certificates and legal opinions. The underwriters reserve the right to withdraw, cancel or modify offers to the public and to reject orders in whole or in part.

The notes are a new issue of securities with no established trading market and will not be listed on any national securities exchange. The underwriters have advised us that they intend to make a market for the notes, but they have no obligation to do so and may discontinue market-making at any time without providing any notice. No assurance can be given as to the liquidity of any trading market for the notes. Notes sold by the underwriters to the public will initially be offered at the public offering prices set forth on the cover page of this prospectus supplement. Any notes sold by the underwriters to securities dealers may be sold at a discount from the public offering price of up to % of the principal amount of the notes. The underwriters may allow, and any such dealer may reallow, a concession not in excess of % of the principal amount of the notes. After the initial offering of the notes to the public, the underwriters may change the offering price and other selling terms.

The following table summarizes the compensation to be paid by us to the underwriters:

Per note

Total

Underwriting discount paid by us

We expect that delivery of the notes will be made to investors on or about the closing date specified on the cover page of this prospectus supplement, which will be the business day following the date of this prospectus supplement. This settlement cycle is referred to as “T+ .” Under Rule 15c6-l under the Exchange Act, trades in the secondary market generally are required to settle in one business day, unless the parties to any such trade expressly agree otherwise. Accordingly, purchasers who wish to trade notes on the date of this prospectus supplement or the next succeeding business days will be required, by virtue of the fact that the notes initially will settle T+ , to specify an alternate settlement cycle at the time of any such trade to prevent a failed settlement. Purchasers of notes who wish to trade notes on the date of this prospectus supplement or the next succeeding business days should consult their own advisors.

We estimate that the total expenses of this offering to be paid by us, excluding underwriting discounts, will be approximately $ .

We have agreed to indemnify the underwriters against certain liabilities, including liabilities under the Securities Act or to contribute to payments that the underwriters may be required to make in respect of any such liabilities.

S-34

TABLE OF CONTENTS

In connection with the offering, the underwriters may engage in stabilizing transactions, over-allotment transactions, syndicate covering transactions and penalty bids in accordance with Regulation M under the Exchange Act.

•

Stabilizing transactions permit bids to purchase the underlying security so long as the stabilizing bids do not exceed a specified maximum.

•

Over-allotment transactions involve sales by the underwriters of notes in excess of the principal amount of notes the underwriters are obligated to purchase, 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.

•

Penalty bids permit the underwriters to reclaim a selling concession from a syndicate member when the notes originally sold by the syndicate member are purchased in a stabilizing transaction or a syndicate covering transaction to cover syndicate short positions.

These stabilizing transactions, over-allotment transactions, syndicate covering transactions and penalty bids may have the effect of raising or maintaining the market price of the notes or preventing or retarding a decline in the market price of the notes. As a result the price of the notes may be higher than the price that might otherwise exist in the open market. These transactions, if commenced, may be discontinued at any time without notice.

The underwriters and their respective affiliates are full service financial institutions engaged in various activities, which may include securities trading, commercial and investment banking, financial advisory, investment management, investment research, principal investment, hedging, financing and brokerage activities. In the ordinary course of business, the underwriters and their respective affiliates have from time to time performed and may in the future perform various financial advisory, commercial banking, investment banking, asset leasing and treasury services for us and our affiliates, for which they received, or will continue to receive, customary fees or compensation.

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 (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 respective subsidiaries. Certain of the underwriters or their affiliates that have a lending relationship with us routinely hedge, and certain other underwriters or their affiliates that have a lending relationship with us may hedge their credit exposure to us consistent with their customary risk management policies. Typically, these underwriters or 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 and our parent’s securities, including potentially the notes offered hereby. Any such credit default swaps or short positions could adversely affect future trading prices of the notes. The underwriters and their respective affiliates may also make investment recommendations or publish or express independent research views in respect of such securities or instruments and may at any time hold, or recommend to clients that they acquire, long or short positions in such securities and instruments.

By using a shelf registration statement, we may sell securities from time to time and in one or more offerings as described in this prospectus. Each time that we offer and sell securities, we will provide a prospectus supplement to this prospectus that contains specific information about the securities being offered and sold and the specific terms of that offering. We may also authorize one or more free writing prospectuses to be provided to you that may contain material information relating to these offerings. The prospectus supplement or free writing prospectus may also add, update or change information contained in this prospectus with respect to that offering. If there is any inconsistency between the information in this prospectus and the applicable prospectus supplement or free writing prospectus, you should rely on the prospectus supplement or free writing prospectus, as applicable.

Our business, financial condition, results of operations and prospects may have changed since those dates. This prospectus incorporates by reference, and any prospectus supplement or free writing prospectus may contain and incorporate by reference, market data and industry statistics and forecasts that are based on independent industry publications and other publicly available information. Although we believe these sources are reliable, we do not guarantee the accuracy or completeness of this information and we have not independently verified this information. In addition, the market and industry data and forecasts that may be included or incorporated by reference in this prospectus, any prospectus supplement or any applicable free writing prospectus may involve estimates, assumptions and other risks and uncertainties and are subject to change based on various factors, including those discussed under the heading “Risk Factors” contained in this prospectus, the applicable prospectus supplement and any applicable free writing prospectus, and under similar headings in other documents that are incorporated by reference into this prospectus and the applicable prospectus supplement.

In addition, historical, current, and forward-looking environmental, social and sustainability-related statements may be based on standards for measuring progress that are still developing, internal controls and processes that continue to evolve, and assumptions that are subject to change in the future.

TABLE OF CONTENTS

OUR COMPANY

General

Established through the combination of Chesapeake Energy Corporation (“Chesapeake”) and Southwestern Energy Company (“Southwestern”) (the “Merger”), Expand Energy is the largest independent natural gas producer in the United States, based on net daily production, and is focused on responsibly developing an abundant supply of natural gas, oil and NGLs to expand energy access for all. Our operations are located in Louisiana in the Haynesville/Bossier Shales, in Pennsylvania in the Marcellus Shale, and in West Virginia and Ohio in the Marcellus and Utica Shales.

Our strategy is to create shareholder value through the responsible development of our significant resource plays while continuing to be a leading provider of natural gas to markets in need. We continue to focus on improving margins through operating efficiencies and financial discipline and improving our ESG performance. To accomplish these goals, we intend to allocate our human resources and capital expenditures to projects we believe offer the highest cash return on capital invested, to deploy leading drilling and completion technology throughout our portfolio, and to take advantage of acquisition and divestiture opportunities to strengthen our portfolio. We also intend to continue to dedicate capital to projects that reduce the environmental impact of our production activities.

Our principal executive offices are located at 6100 North Western Avenue, Oklahoma City, Oklahoma 73118, and our telephone number is (405) 848-8000.

TABLE OF CONTENTS

RISK FACTORS

Investment in any securities offered pursuant to this prospectus and the applicable prospectus supplement involves risks. Before deciding whether to invest in our securities, you should carefully consider the risk factors incorporated by reference to our most recent Annual Report on Form 10-K and any subsequent Quarterly Reports on Form 10-Q or Current Reports on Form 8-K, and all other information contained or incorporated by reference into this prospectus, including but not limited to, the matters addressed in the section titled “Cautionary Statement Regarding Forward-Looking Statements,” as updated by our subsequent filings under the Exchange Act, and the risk factors and other information contained in or incorporated by reference in the applicable prospectus supplement and any applicable free writing prospectus. The occurrence of any of these risks might cause you to lose all or part of your investment in the offered securities. There may be other unknown or unpredictable economic, business, competitive, regulatory or other factors that could have material adverse effects on our future results. Past financial performance may not be a reliable indicator of future performance, and historical trends should not be used to anticipate results or trends in future periods. If any of these risks actually occurs, our business, financial condition, results of operations or cash flow could be seriously harmed. This could cause the trading price of our securities to decline, resulting in a loss of all or part of your investment. Please also carefully read the section entitled “Cautionary Statement Regarding Forward-Looking Statements” included in our most recent Annual Report on Form 10-K and any subsequent Quarterly Reports on Form 10-Q or Current Reports on Form 8-K.

USE OF PROCEEDS

We intend to use the net proceeds from the sale of the securities as set forth in the applicable prospectus supplement.

TABLE OF CONTENTS

DESCRIPTION OF CAPITAL STOCK

The following description of our capital stock is not complete and may not contain all the information you should consider before investing in our capital stock. This description is summarized from, and qualified in its entirety by reference to, our certificate of incorporation, which has been publicly filed with the SEC. See “Where You Can Find More Information; Incorporation by Reference.”

The Third Amended and Restated Certificate of Incorporation of Expand Energy (the “Expand Energy Charter”) provides that the Company is authorized to issue 495 million shares of capital stock, divided into two classes consisting of (a) 450 million shares of common stock, par value $0.01 per share, and (b) 45 million shares of preferred stock, par value $0.01 per share.

As of November 18, 2024, there were 231,096,625 shares of Common Stock and 0 shares of preferred stock outstanding and 1,260,494, 3,099,093 and 3,680,062 Class A Warrants to purchase Common Stock (“Class A Warrants”), Class B Warrants to purchase Common Stock (“Class B Warrants”) and Class C Warrants to purchase Common Stock (“Class C Warrants”), respectively, outstanding (collectively, the “Warrants”).

Common Stock

Each holder of shares of Common Stock, as such, shall be entitled to one vote for each share of Common Stock held of record by such holder on all matters on which shareholders generally are entitled to vote.

Subject to the rights of any then-outstanding shares of preferred stock, the holders of Common Stock may receive such dividends as the Board of Directors (the “Board”) may declare in its discretion out of legally available funds. Holders of Common Stock will be entitled to receive all of the remaining assets of the Company available for distribution to its shareholders, ratably in proportion to the number of shares of Common Stock held by them.

Voting Rights

Each holder of Common Stock is entitled to one vote for each share on all matters submitted to a vote of the shareholders, including the election or removal of directors.

The Third Amended and Restated Bylaws of Expand Energy (the “Expand Energy Bylaws”) provide that the number of directors which shall constitute the whole board of directors shall not be less than three (3) nor more than eleven (11), and shall be determined by resolution adopted by a vote of a majority of the entire Board then in office, or at an annual or special meeting of shareholders by the affirmative vote of at least a majority of the then outstanding shares of the Company’s capital stock entitled to vote thereon. No reduction in number shall have the effect of removing any director prior to the expiration of his term. No person may stand for election to, or be elected to, the Board or be appointed by the directors to fill a vacancy on the Board who shall have made, or be making, improper or unlawful use of the Company’s confidential information. All elections of directors shall be by written ballot unless otherwise provided in the Expand Energy Charter. However, if authorized by the board of directors in its sole discretion, the ballot may be submitted by electronic transmission, provided that any such electronic transmission must either set forth, or be submitted with, information from which it can be determined that the electronic transmission was authorized by the shareholder or proxyholder. Vacancies and newly created directorships resulting from any increase in the authorized number of directors may be filled by a majority of the directors then in office, though less than a quorum, and the directors so chosen shall hold office until the next annual meeting of shareholders and until his or her successor is duly elected and qualified, or until his or her earlier resignation or removal.

Dividends

The Board may from time to time declare, and the Company may pay, dividends (payable in cash, property or shares of the Company’s capital stock) on the Company’s outstanding shares of capital stock, subject to applicable law and the Expand Energy Charter and may be paid in cash, in property or in shares of the capital stock, or in any combination thereof.

TABLE OF CONTENTS

Liquidation

Except as otherwise required by the Expand Energy Bylaws or Expand Energy Charter, the common stock will have all rights and privileges typically associated with such securities as set forth in the Oklahoma General Corporation Act (the “OGCA”) in relation to rights upon liquidation.

Preferred Stock

The Expand Energy Charter provides that shares of preferred stock may be issued from time to time in one or more series. The Board will be authorized to fix the voting rights, if any, designations, powers, preferences, the relative, participating, optional or other special rights and any qualifications, limitations and restrictions thereof, applicable to the shares of each series. The Board may, without shareholder approval, issue preferred stock with voting and other rights that could adversely affect the voting power and other rights of the holders of the Common Stock and could have anti-takeover effects. The ability of the Board to issue preferred stock without shareholder approval could have the effect of delaying, deferring or preventing a change of control of the Company or the removal of existing management. The Company has no preferred stock outstanding at the date hereof.

Warrants

Currently each holder of a Class A Warrant is entitled to purchase 1.22 shares of the Company’s Common Stock for $22.576 per share, each holder of a Class B Warrant is entitled to purchase 1.22 shares of the Company’s Common Stock for $26.254 per share, and each holder of a Class C Warrant is entitled to purchase 1.22 shares of the Company’s Common Stock for $29.562 per share, subject to certain adjustments. Warrants must be exercised for a whole share of Common Stock. The Warrants will expire on February 9, 2026, or earlier upon liquidation.

The Warrants have been issued in registered form pursuant to each applicable warrant agreement, by and between Equiniti Trust Company, as warrant agent, and us (each, a “Warrant Agreement”). You should review a copy of each applicable Warrant Agreement, which is filed as an exhibit to this prospectus, for a complete description of the terms and conditions applicable to the Warrants. Each Warrant Agreement provides that the terms of the Warrants may be amended without the consent of any holder to cure any ambiguity or to correct or supplement any defective provision, but any amendment, modification or waiver that adversely affects the interests of a holder of the applicable Warrant disproportionally relative to any other holder in any material respect requires the approval of each affected warrant holder.

In addition, if we, at any time while the Warrants are outstanding and unexpired, (i) declare a dividend or make a distribution on our Common Stock in Common Stock, (ii) split, subdivide, recapitalize, restructure or reclassify the outstanding Common Stock into a greater number of shares of Common Stock or effect a similar transaction or (iii) combine, recapitalize, restructure or reclassify the outstanding Common Stock into a smaller number of shares of Common Stock or effect a similar transaction, the number of shares of Common Stock issuable upon exercise of a warrant at the time of the record date for such dividend or distribution or the effective date of such split, subdivision, combination, recapitalization, restructuring, reclassification or similar transaction shall be proportionately adjusted so that the applicable warrant holder, after such date, shall be entitled to purchase the number of shares of Common Stock which such warrant holder would have owned or been entitled to receive on such date had such applicable warrants been exercised immediately prior to such date. In such event, the exercise price in effect at the time of the record date for such dividend or distribution or the effective date of such split, subdivision, combination, recapitalization, restructuring, reclassification or similar transaction shall be adjusted to the number obtained by dividing (x) the product of (i) the number of shares of Common Stock issuable upon the exercise of a warrant before such adjustment and (ii) the exercise price in effect immediately prior to the record date or effective date, as the case may be, for such dividend, distribution, split, subdivision, combination, recapitalization, restructuring, reclassification or similar transaction giving rise to this adjustment by (y) the new number of shares of Common Stock issuable upon exercise of the applicable warrants determined pursuant to the immediately preceding sentence.

The Warrants may be exercised upon surrender of the warrant certificate on or prior to the expiration date at the offices of the warrant agent, with the exercise form on the reverse side of the warrant certificate

TABLE OF CONTENTS

completed and executed as indicated, accompanied by full payment of the exercise price (or on a cashless basis, if applicable), by certified or official bank check payable to us, for the number of warrants being exercised. The warrant holders do not have the rights or privileges of holders of Common Stock and any voting rights until they exercise their warrants and receive shares of Common Stock. After the issuance of shares of Common Stock upon exercise of the warrants, each holder will be entitled to one vote for each share held of record on all matters to be voted on by shareholders.

Certain Anti-Takeover Provisions

Oklahoma General Corporation Act

Some provisions of Oklahoma law, the Expand Energy Charter and the Expand Energy Bylaws summarized below could make certain change of control transactions more difficult, including acquisitions of the Company by means of a tender offer, proxy contest or otherwise, as well as removal of the incumbent directors. These provisions may have the effect of preventing changes in management. It is possible that these provisions would make it more difficult to accomplish or deter transactions that a shareholder might consider in his or her best interest, including those attempts that might result in a premium over the market price for the Common Stock.

Number and Election of Directors

The Expand Energy Bylaws provide that the Board shall be comprised of no less than three and no more than 11 directors, with the number of directors to be fixed from time to time by resolution adopted by the Board.

Calling of Special Meetings of Shareholders

The Expand Energy Bylaws provide that special meetings of shareholders may be called only by (i) the chairman of the Board, (ii) the chief executive officer or the president of the Company, (iii) the Board acting pursuant to a resolution adopted by a majority of the directors of the Board then in office or (iv) the secretary of the Company upon the delivery of a written request to the Company by the holders of at least 35% of the voting power of the Company’s then outstanding capital stock in the manner provided in the Expand Energy Bylaws.

Amendments to the Expand Energy Charter and Expand Energy Bylaws

The Expand Energy Charter may be adopted, repealed, altered, amended or rescinded by the affirmative vote of the holders of at least a majority of the shares of the Company’s then outstanding capital stock entitled to vote thereon, except that the affirmative vote of the holders of at least sixty percent (60%) of the voting power of the Company’s then outstanding capital stock entitled to vote is required to amend, repeal, or adopt any provision inconsistent with Articles V, VI, VII, VIII, IX, X or XI of the Expand Energy Charter.

The Expand Energy Bylaws may be adopted, repealed, altered, amended or rescinded by either the Board or the affirmative vote of the holders of at least a majority of the shares of the Company’s then outstanding capital stock entitled to vote thereon (a “Shareholder Adopted Bylaw”), except that Section 5.8, Section 5.9 and Article VII of the Expand Energy Bylaws may not be amended by the Board or by a Shareholder Adopted Bylaw without the approval of sixty percent (60%) of the voting power of the then outstanding shares of the Company’s capital stock entitled to vote at an election of directors. In addition, any Shareholder Adopted Bylaw that is approved by sixty percent (60%) or more of the voting power of the Company’s then outstanding capital stock entitled to vote at an election of directors (a “Supermajority Bylaw”) may only be amended, altered or repealed by the affirmative vote of holders of at least sixty percent (60%) of the voting power of the Company’s then outstanding capital stock entitled to vote at an election of directors, and the Board may not adopt any new bylaw, or amend, alter or repeal any existing bylaw, if such adoption, amendment, alteration or repeal would be directly contrary to a Supermajority Bylaw.

Other Limitations on Shareholder Actions

Advance notice is required for shareholders to nominate directors or to submit proposals for consideration at meetings of shareholders. These procedures provide that notice of shareholder proposals

TABLE OF CONTENTS

must be timely given in writing to the corporate secretary prior to the meeting at which the action is to be taken. Generally, to be timely, notice must be received at the principal executive offices not less than 90 days nor more than 120 days prior to the anniversary of the immediately preceding annual meeting of shareholders. The Expand Energy Bylaws specify in detail the requirements as to form and content of all shareholder notices. These requirements may preclude shareholders from bringing matters before the shareholders at an annual or special meeting. The Expand Energy Bylaws also describe certain criteria for when shareholder-requested meetings need not be held.

Directors may be removed from office at any time by the affirmative vote of holders of at least a majority of the outstanding shares of common stock entitled generally to vote in the election of directors.

Newly Created Directorships and Vacancies on the Board

Under the Expand Energy Bylaws, any newly created directorships resulting from any increase in the number of directors and any vacancies on the Board for any reason may be filled by a majority vote of the directors then in office, even if less than a quorum, and the directors so chosen shall hold office until the next annual meeting of shareholders and until his or her successor is duly elected and qualified, or until his or her earlier resignation or removal.

Authorized but Unissued Shares

The Company’s authorized but unissued shares of common stock are available for future issuance. The Company may use these additional shares of common stock for a variety of corporate purposes, including future public offerings to raise additional capital, acquisitions and employee benefit plans. The existence of authorized but unissued shares of common stock could render more difficult or discourage an attempt to obtain control of the Company by means of a proxy contest, tender offer, merger or otherwise.

Exclusive Forum

The Expand Energy Charter provides that, unless the Company consents in writing to the selection of an alternative forum, the state courts within the State of Oklahoma (or, if no such state court has jurisdiction, the United States District Court for the Western District of Oklahoma) will be the sole and exclusive forum for (i) any derivative action or proceeding brought on the Company’s behalf, (ii) any action asserting a claim of breach of a fiduciary duty owed by any current or former directors, officers, other employees or shareholders to the Company or to the shareholders, (iii) any action asserting a claim arising pursuant to any provision of the Oklahoma General Corporation Act, the Expand Energy Charter or the Expand Energy Bylaws (as each may be amended from time to time), or (iv) any action asserting a claim related to or involving the Company that is governed by the internal affairs doctrine.

Additionally, Article VIII of the Expand Energy Charters provides that unless we consent in writing to the selection of an alternative forum, the federal courts shall be the sole and exclusive forum for the resolution of any complaint asserting a cause of action arising under the Securities Act against us or any of our directors, officers, other employees or agents. Section 22 of the Securities Act, however, created concurrent jurisdiction for federal and state courts over all suits brought to enforce any duty or liability created by the Securities Act or the rules and regulations thereunder. However, we note that there is uncertainty as to whether a court would enforce such provisions, and that investors cannot waive compliance with the federal securities laws and the rules and regulations thereunder. The foregoing descriptions of the Expand Energy Charter and Expand Energy Bylaws do not purport to be complete and are qualified in their entirety by reference to the Expand Energy Charter and Expand Energy Bylaws, copies of which are attached hereto as Exhibits 3.1 and 3.2 and incorporated herein by reference.

TABLE OF CONTENTS

securities is payable in a foreign currency or currencies or a foreign currency unit or units, we will provide you with information on the restrictions, elections, general tax considerations, specific terms and other information with respect to that issue of debt securities and such foreign currency or currencies or foreign currency unit or units in the applicable prospectus supplement.

Transfer and Exchange

Each debt security will be represented by either one or more global securities registered in the name of The Depository Trust Company (the “Depositary”), or a nominee of the Depositary (we will refer to any debt security represented by a global debt security as a “book-entry debt security”), or a certificate issued in definitive registered form (we will refer to any debt security represented by a certificated security as a “certificated debt security”) as set forth in the applicable prospectus supplement. Except as set forth under the heading “Global Debt Securities and Book-Entry System” below, book-entry debt securities will not be issuable in certificated form.

Certificated Debt Securities. You may transfer or exchange certificated debt securities at any office we maintain for this purpose in accordance with the terms of the indenture. (Section 2.4) No service charge will be made for any transfer or exchange of certificated debt securities, but we may require payment of a sum sufficient to cover any tax or other governmental charge payable in connection with a transfer or exchange. (Section 2.7)

You may effect the transfer of certificated debt securities and the right to receive the principal of, premium and interest on certificated debt securities only by surrendering the certificate representing those certificated debt securities and either reissuance by us or the trustee of the certificate to the new holder or the issuance by us or the trustee of a new certificate to the new holder.

Global Debt Securities and Book-Entry System. Each global debt security representing book-entry debt securities will be deposited with, or on behalf of, the Depositary, and registered in the name of the Depositary or a nominee of the Depositary. Please see “Global Securities.”

Covenants

We will set forth in the applicable prospectus supplement any restrictive covenants applicable to any issue of debt securities. (Article IV)

No Protection in the Event of a Change of Control

Unless we state otherwise in the applicable prospectus supplement, the debt securities will not contain any provisions which may afford holders of the debt securities protection in the event we have a change in control or in the event of a highly leveraged transaction (whether or not such transaction results in a change in control) which could adversely affect holders of debt securities.

Consolidation, Merger and Sale of Assets

We may not consolidate with or merge with or into, or convey, transfer or lease all or substantially all of our properties and assets to any person (a “successor person”) unless:

•

we are the surviving entity or the successor person (if other than Expand Energy) is a corporation, partnership, trust or other entity organized and validly existing under the laws of any U.S. domestic jurisdiction and expressly assumes our obligations on the debt securities and under the indenture; and

•

immediately after giving effect to the transaction, no Default or Event of Default, shall have occurred and be continuing.

Notwithstanding the above, any of our subsidiaries may consolidate with, merge into or transfer all or part of its properties to us. (Section 5.1)

Events of Default

“Event of Default” means with respect to any series of debt securities, any of the following:

TABLE OF CONTENTS

•

default in the payment of any interest upon any debt security of that series when it becomes due and payable, and continuance of such default for a period of 30 days (unless the entire amount of the payment is deposited by us with the trustee or with a paying agent prior to the expiration of the 30-day period);

•

default in the payment of principal of any security of that series at its maturity;

•

default in the performance or breach of any other covenant or warranty by us in the indenture (other than a covenant or warranty that has been included in the indenture solely for the benefit of a series of debt securities other than that series), which default continues uncured for a period of 60 days after we receive written notice from the trustee or Expand Energy and the trustee receive written notice from the holders of not less than 25% in principal amount of the outstanding debt securities of that series as provided in the indenture;

•

certain voluntary or involuntary events of bankruptcy, insolvency or reorganization of Expand Energy;

•

any other Event of Default provided with respect to debt securities of that series that is described in the applicable prospectus supplement. (Section 6.1)

No Event of Default with respect to a particular series of debt securities (except as to certain events of bankruptcy, insolvency or reorganization) necessarily constitutes an Event of Default with respect to any other series of debt securities. (Section 6.1) The occurrence of certain Events of Default or an acceleration under the indenture may constitute an event of default under certain indebtedness of ours or our subsidiaries outstanding from time to time.

We will provide the trustee written notice of any Default or Event of Default within 30 days of becoming aware of the occurrence of such Default or Event of Default, which notice will describe in reasonable detail the status of such Default or Event of Default and what action we are taking or propose to take in respect thereof. (Section 6.1)

If an Event of Default with respect to debt securities of any series at the time outstanding occurs and is continuing, then the trustee or the holders of not less than 25% in principal amount of the outstanding debt securities of that series may, by a notice in writing to us (and to the trustee if given by the holders), declare to be due and payable immediately the principal of (or, if the debt securities of that series are discount securities, that portion of the principal amount as may be specified in the terms of that series) and accrued and unpaid interest, if any, on all debt securities of that series. In the case of an Event of Default resulting from certain events of bankruptcy, insolvency or reorganization, the principal (or such specified amount) of and accrued and unpaid interest, if any, on all outstanding debt securities will become and be immediately due and payable without any declaration or other act on the part of the trustee or any holder of outstanding debt securities. At any time after a declaration of acceleration with respect to debt securities of any series has been made, but before a judgment or decree for payment of the money due has been obtained by the trustee, the holders of a majority in principal amount of the outstanding debt securities of that series may rescind and annul the acceleration if all Events of Default, other than the non-payment of accelerated principal and interest, if any, with respect to debt securities of that series, have been cured or waived as provided in the indenture. (Section 6.2) We refer you to the prospectus supplement relating to any series of debt securities that are discount securities for the particular provisions relating to acceleration of a portion of the principal amount of such discount securities upon the occurrence of an Event of Default.

The indenture provides that the trustee may refuse to perform any duty or exercise any of its rights or powers under the indenture unless the trustee receives indemnity satisfactory to it against any cost, liability or expense which might be incurred by it in performing such duty or exercising such right or power. (Section 7.1(e)) Subject to certain rights of the trustee, the holders of a majority in principal amount of the outstanding debt securities of any series will have the right to direct the time, method and place of conducting any proceeding for any remedy available to the trustee or exercising any trust or power conferred on the trustee with respect to the debt securities of that series. (Section 6.12)

No holder of any debt security of any series will have any right to institute any proceeding, judicial or otherwise, with respect to the indenture or for the appointment of a receiver or trustee, or for any remedy under the indenture, unless:

TABLE OF CONTENTS

•

that holder has previously given to the trustee written notice of a continuing Event of Default with respect to debt securities of that series; and

•

the holders of not less than 25% in principal amount of the outstanding debt securities of that series have made written request, and offered indemnity or security satisfactory to the trustee, to the trustee to institute the proceeding as trustee, and the trustee has not received from the holders of not less than a majority in principal amount of the outstanding debt securities of that series a direction inconsistent with that request and has failed to institute the proceeding within 60 days. (Section 6.7)

Notwithstanding any other provision in the indenture, the holder of any debt security will have an absolute and unconditional right to receive payment of the principal of, premium and any interest on that debt security on or after the due dates expressed in that debt security and to institute suit for the enforcement of payment. (Section 6.8)

The indenture requires us, within 120 days after the end of our fiscal year, to furnish to the trustee a statement as to compliance with the indenture. (Section 4.3) If a Default or Event of Default occurs and is continuing with respect to the securities of any series and if it is known to a responsible officer of the trustee, the trustee shall mail to each Securityholder of the securities of that series notice of a Default or Event of Default within 90 days after it occurs or, if later, after a responsible officer of the trustee has knowledge of such Default or Event of Default. The indenture provides that the trustee may withhold notice to the holders of debt securities of any series of any Default or Event of Default (except in payment on any debt securities of that series) with respect to debt securities of that series if the trustee determines in good faith that withholding notice is in the interest of the holders of those debt securities. (Section 7.5)

Modification and Waiver

We and the trustee may modify, amend or supplement the indenture or the debt securities of any series without the consent of any holder of any debt security:

•

to cure any ambiguity, defect or inconsistency;

•

to comply with covenants in the indenture described above under the heading “Consolidation, Merger and Sale of Assets”;

•

to provide for uncertificated securities in addition to or in place of certificated securities;

•

to add guarantees with respect to debt securities of any series or secure debt securities of any series;

•

to surrender any of our rights or powers under the indenture;

•

to add covenants or events of default for the benefit of the holders of debt securities of any series;

to provide for the issuance of and establish the form and terms and conditions of debt securities of any series as permitted by the indenture;

to effect the appointment of a successor trustee with respect to the debt securities of any series and to add to or change any of the provisions of the indenture to provide for or facilitate administration by more than one trustee;

•

to comply with requirements of the SEC in order to effect or maintain the qualification of the indenture under the Trust Indenture Act; or

•

to conform the text of the indenture or any debt securities to any provision of the “Description of Debt Securities” or “Description of the Notes” (or comparable) section in any offering memorandum, prospectus or prospectus supplement of the Company prepared from time to time with respect to the offer and sale of debt securities of any series, to the extent that such provision was intended to be a complete description or summary of a provision of the indenture or the debt securities, as determined in good faith by the Company (which intent will be established by an officer’s certificate). (Section 9.1)

TABLE OF CONTENTS

We may also modify and amend the indenture with the consent of the holders of at least a majority in principal amount of the outstanding debt securities of each series affected by the modifications or amendments. We may not make any modification or amendment without the consent of the holders of each affected debt security then outstanding if that amendment will:

•

reduce the amount of debt securities whose holders must consent to an amendment, supplement or waiver;

•

reduce the rate of or extend the time for payment of interest (including default interest) on any debt security;

•

reduce the principal of or premium on or change the fixed maturity of any debt security or reduce the amount of, or postpone the date fixed for, the payment of any sinking fund or analogous obligation with respect to any series of debt securities;

•

reduce the principal amount of discount securities payable upon acceleration of maturity;

•

waive a default in the payment of the principal of, premium or interest on any debt security (except a rescission of acceleration of the debt securities of any series by the holders of at least a majority in aggregate principal amount of the then outstanding debt securities of that series and a waiver of the payment default that resulted from such acceleration);

•

make the principal of or premium or interest on any debt security payable in currency other than that stated in the debt security;

•

make any change to certain provisions of the indenture relating to, among other things, the right of holders of debt securities to receive payment of the principal of, premium and interest on those debt securities and to institute suit for the enforcement of any such payment and to waivers or amendments; or

•

waive a redemption payment with respect to any debt security. (Section 9.3)

Except for certain specified provisions, the holders of at least a majority in principal amount of the outstanding debt securities of any series may on behalf of the holders of all debt securities of that series waive our compliance with provisions of the indenture. (Section 9.2) The holders of a majority in principal amount of the outstanding debt securities of any series may on behalf of the holders of all the debt securities of such series waive any past default under the indenture with respect to that series and its consequences, except a default in the payment of the principal of, premium or any interest on any debt security of that series; provided, however, that the holders of a majority in principal amount of the outstanding debt securities of any series may rescind an acceleration and its consequences, including any related payment default that resulted from the acceleration. (Section 6.13)

Defeasance of Debt Securities and Certain Covenants in Certain Circumstances

Legal Defeasance. The indenture provides that, unless otherwise provided by the terms of the applicable series of debt securities, we may be discharged from any and all obligations in respect of the debt securities of any series (subject to certain exceptions). We will be so discharged upon the irrevocable deposit with the trustee, in trust, of money and/or U.S. government obligations or, in the case of debt securities denominated in a single currency other than U.S. Dollars, government obligations of the government that issued or caused to be issued such currency, that, through the payment of interest and principal in accordance with their terms, will provide money or U.S. government obligations in an amount sufficient in the opinion of a nationally recognized investment bank, appraisal firm or firm of independent public accountants (or if no nationally recognized investment bank, appraisal firm or firm of independent public accountants agrees to express such opinion, a certificate from the chief financial officer of Expand Energy expressing his or her opinion) to pay and discharge each installment of principal, premium and interest on and any mandatory sinking fund payments in respect of the debt securities of that series on the stated maturity of those payments in accordance with the terms of the indenture and those debt securities.

This discharge may occur only if, among other things, we have delivered to the trustee an opinion of counsel stating that we have received from, or there has been published by, the United States Internal Revenue Service a ruling or, since the date of execution of the indenture, there has been a change in the applicable

TABLE OF CONTENTS

United States federal income tax law, in either case to the effect that, and based thereon such opinion shall confirm that, the holders of the debt securities of that series will not recognize income, gain or loss for United States federal income tax purposes as a result of the deposit, defeasance and discharge and will be subject to United States federal income tax on the same amounts and in the same manner and at the same times as would have been the case if the deposit, defeasance and discharge had not occurred. (Section 8.3)

Defeasance of Certain Covenants. The indenture provides that, unless otherwise provided by the terms of the applicable series of debt securities, upon compliance with certain conditions:

•

we may omit to comply with the covenant described under the heading “Consolidation, Merger and Sale of Assets” and certain other covenants set forth in the indenture, as well as any additional covenants which may be set forth in the applicable prospectus supplement; and

•

any omission to comply with those covenants will not constitute a Default or an Event of Default with respect to the debt securities of that series (“covenant defeasance”).

The conditions include:

•

depositing with the trustee money and/or U.S. government obligations or, in the case of debt securities denominated in a single currency other than U.S. Dollars, government obligations of the government that issued or caused to be issued such currency, that, through the payment of interest and principal in accordance with their terms, will provide money in an amount sufficient in the opinion of a nationally recognized investment bank, appraisal firm or firm of independent public accountants (or if no nationally recognized investment bank, appraisal firm or firm of independent public accountants agrees to express such opinion, a certificate from the chief financial officer of Expand Energy expressing his or her opinion) to pay and discharge each installment of principal of, premium and interest on and any mandatory sinking fund payments in respect of the debt securities of that series on the stated maturity of those payments in accordance with the terms of the indenture and those debt securities; and

•

delivering to the trustee an opinion of counsel to the effect that the holders of the debt securities of that series will not recognize income, gain or loss for United States federal income tax purposes as a result of the deposit and related covenant defeasance and will be subject to United States federal income tax on the same amounts and in the same manner and at the same times as would have been the case if the deposit and related covenant defeasance had not occurred. (Section 8.4)

No Personal Liability of Directors, Officers, Employees or Securityholders

None of our past, present or future directors, officers, employees or securityholders, as such, will have any liability for any of our obligations under the debt securities or the indenture or for any claim based on, or in respect or by reason of, such obligations or their creation. By accepting a debt security, each holder waives and releases all such liability. This waiver and release is part of the consideration for the issue of the debt securities. However, this waiver and release may not be effective to waive liabilities under U.S. federal securities laws, and it is the view of the SEC that such a waiver is against public policy.

Governing Law

The indenture and the debt securities, including any claim or controversy arising out of or relating to the indenture or the securities, will be governed by the laws of the State of New York.

The indenture will provide that we, the trustee and the holders of the debt securities (by their acceptance of the debt securities) irrevocably waive, to the fullest extent permitted by applicable law, any and all right to trial by jury in any legal proceeding arising out of or relating to the indenture, the debt securities or the transactions contemplated thereby.

The indenture will provide that any legal suit, action or proceeding arising out of or based upon the indenture or the transactions contemplated thereby may be instituted in the federal courts of the United States of America located in the City of New York or the courts of the State of New York in each case located in the City of New York, and we, the trustee and the holder of the debt securities (by their acceptance of the debt securities) irrevocably submit to the non-exclusive jurisdiction of such courts in any such suit, action

TABLE OF CONTENTS

or proceeding. The indenture will further provide that service of any process, summons, notice or document by mail (to the extent allowed under any applicable statute or rule of court) to such party’s address set forth in the indenture will be effective service of process for any suit, action or other proceeding brought in any such court. The indenture will further provide that we, the trustee and the holders of the debt securities (by their acceptance of the debt securities) irrevocably and unconditionally waive any objection to the laying of venue of any suit, action or other proceeding in the courts specified above and irrevocably and unconditionally waive and agree not to plead or claim any such suit, action or other proceeding has been brought in an inconvenient forum.

The global securities will be deposited with, or on behalf of, The Depository Trust Company, New York, New York, as depositary (“DTC”), and registered in the name of Cede & Co., the nominee of DTC. Unless and until it is exchanged for individual certificates evidencing securities under the limited circumstances described below, a global security may not be transferred except as a whole by the depositary to its nominee or by the nominee to the depositary, or by the depositary or its nominee to a successor depositary or to a nominee of the successor depositary.

DTC has advised us that it is:

•

a limited-purpose trust company organized under the New York Banking Law;

•

a “banking organization” within the meaning of the New York Banking Law;

•

a member of the Federal Reserve System;

•

a “clearing corporation” within the meaning of the New York Uniform Commercial Code; and

•

a “clearing agency” registered pursuant to the provisions of Section 17A of the Exchange Act.

DTC holds securities that its participants deposit with DTC. DTC also facilitates the settlement among its participants of securities transactions, such as transfers and pledges, in deposited securities through electronic computerized book-entry changes in participants’ accounts, thereby eliminating the need for physical movement of securities certificates. “Direct participants” in DTC include securities brokers and dealers, including underwriters, banks, trust companies, clearing corporations and other organizations. DTC is a wholly-owned subsidiary of The Depository Trust & Clearing Corporation, or DTCC. DTCC is the holding company for DTC, National Securities Clearing Corporation and Fixed Income Clearing Corporation, all of which are registered clearing agencies. DTCC is owned by the users of its regulated subsidiaries. Access to the DTC system is also available to others, which we sometimes refer to as indirect participants, that clear through or maintain a custodial relationship with a direct participant, either directly or indirectly. The rules applicable to DTC and its participants are on file with the SEC.

Purchases of securities under the DTC system must be made by or through direct participants, which will receive a credit for the securities on DTC’s records. The ownership interest of the actual purchaser of a security, which we sometimes refer to as a beneficial owner, is in turn recorded on the direct and indirect participants’ records. Beneficial owners of securities will not receive written confirmation from DTC of their purchases. However, beneficial owners are expected to receive written confirmations providing details of their transactions, as well as periodic statements of their holdings, from the direct or indirect participants through which they purchased securities. Transfers of ownership interests in global securities are to be accomplished by entries made on the books of participants acting on behalf of beneficial owners. Beneficial owners will not receive certificates representing their ownership interests in the global securities, except under the limited circumstances described below.

To facilitate subsequent transfers, all global securities deposited by direct participants with DTC will be registered in the name of DTC’s partnership nominee, Cede & Co., or such other name as may be requested by an authorized representative of DTC. The deposit of securities with DTC and their registration in the name of Cede & Co. or such other nominee will not change the beneficial ownership of the securities. DTC has no knowledge of the actual beneficial owners of the securities. DTC’s records reflect only the identity of the direct participants to whose accounts the securities are credited, which may or may not be the beneficial owners. The participants are responsible for keeping account of their holdings on behalf of their customers.

So long as the securities are in book-entry form, you will receive payments and may transfer securities only through the facilities of the depositary and its direct and indirect participants. We will maintain an office or agency in the location specified in the prospectus supplement for the applicable securities, where notices and demands in respect of the securities and the indenture may be delivered to us and where certificated securities may be surrendered for payment, registration of transfer or exchange.

TABLE OF CONTENTS

Conveyance of notices and other communications by DTC to direct participants, by direct participants to indirect participants and by direct participants and indirect participants to beneficial owners will be governed by arrangements among them, subject to any legal requirements in effect from time to time.

Redemption notices will be sent to DTC. If less than all of the securities of a particular series are being redeemed, DTC’s practice is to determine by lot the amount of the interest of each direct participant in the securities of such series to be redeemed.

Neither DTC nor Cede & Co. (or such other DTC nominee) will consent or vote with respect to the securities. Under its usual procedures, DTC will mail an omnibus proxy to us as soon as possible after the record date. The omnibus proxy assigns the consenting or voting rights of Cede & Co. to those direct participants to whose accounts the securities of such series are credited on the record date, identified in a listing attached to the omnibus proxy.

So long as securities are in book-entry form, we will make payments on those securities to the depositary or its nominee, as the registered owner of such securities, by wire transfer of immediately available funds. If securities are issued in definitive certificated form under the limited circumstances described below and unless if otherwise provided in the description of the applicable securities herein or in the applicable prospectus supplement, we will have the option of making payments by check mailed to the addresses of the persons entitled to payment or by wire transfer to bank accounts in the United States designated in writing to the applicable trustee or other designated party at least 15 days before the applicable payment date by the persons entitled to payment, unless a shorter period is satisfactory to the applicable trustee or other designated party.

Redemption proceeds, distributions and dividend payments on the securities will be made to Cede & Co., or such other nominee as may be requested by an authorized representative of DTC. DTC’s practice is to credit direct participants’ accounts upon DTC’s receipt of funds and corresponding information from us on the payment date in accordance with their respective holdings shown on DTC records. Payments by participants to beneficial owners will be governed by standing instructions and customary practices, as is the case with securities held for the account of customers in bearer form or registered in “street name.” Those payments will be the responsibility of participants and not of DTC or us, subject to any statutory or regulatory requirements in effect from time to time. Payment of redemption proceeds, distributions and dividend payments to Cede & Co., or such other nominee as may be requested by an authorized representative of DTC, is our responsibility, disbursement of payments to direct participants is the responsibility of DTC, and disbursement of payments to the beneficial owners is the responsibility of direct and indirect participants.

Except under the limited circumstances described below, purchasers of securities will not be entitled to have securities registered in their names and will not receive physical delivery of securities. Accordingly, each beneficial owner must rely on the procedures of DTC and its participants to exercise any rights under the securities and the indenture.

The laws of some jurisdictions may require that some purchasers of securities take physical delivery of securities in definitive form. Those laws may impair the ability to transfer or pledge beneficial interests in securities.

DTC may discontinue providing its services as securities depositary with respect to the securities at any time by giving reasonable notice to us. Under such circumstances, in the event that a successor depositary is not obtained, securities certificates are required to be printed and delivered.

As noted above, beneficial owners of a particular series of securities generally will not receive certificates representing their ownership interests in those securities. However, if:

•

DTC notifies us that it is unwilling or unable to continue as a depositary for the global security or securities representing such series of securities or if DTC ceases to be a clearing agency registered under the Exchange Act at a time when it is required to be registered and a successor depositary is not appointed within 90 days of the notification to us or of our becoming aware of DTC’s ceasing to be so registered, as the case may be;

TABLE OF CONTENTS

•

we determine, in our sole discretion, not to have such securities represented by one or more global securities; or

•

an Event of Default has occurred and is continuing with respect to such series of securities,

we will prepare and deliver certificates for such securities in exchange for beneficial interests in the global securities. Any beneficial interest in a global security that is exchangeable under the circumstances described in the preceding sentence will be exchangeable for securities in definitive certificated form registered in the names that the depositary directs. It is expected that these directions will be based upon directions received by the depositary from its participants with respect to ownership of beneficial interests in the global securities.

Euroclear and Clearstream

If so provided in the applicable prospectus supplement, you may hold interests in a global security through Clearstream Banking S.A., which we refer to as “Clearstream,” or Euroclear Bank S.A./N.V., as operator of the Euroclear System, which we refer to as “Euroclear,” either directly if you are a participant in Clearstream or Euroclear or indirectly through organizations which are participants in Clearstream or Euroclear. Clearstream and Euroclear will hold interests on behalf of their respective participants through customers’ securities accounts in the names of Clearstream and Euroclear, respectively, on the books of their respective U.S. depositaries, which in turn will hold such interests in customers’ securities accounts in such depositaries’ names on DTC’s books.

Clearstream and Euroclear are securities clearance systems in Europe. Clearstream and Euroclear hold securities for their respective participating organizations and facilitate the clearance and settlement of securities transactions between those participants through electronic book-entry changes in their accounts, thereby eliminating the need for physical movement of certificates.

Payments, deliveries, transfers, exchanges, notices and other matters relating to beneficial interests in global securities owned through Euroclear or Clearstream must comply with the rules and procedures of those systems. Transactions between participants in Euroclear or Clearstream, on one hand, and other participants in DTC, on the other hand, are also subject to DTC’s rules and procedures.

Investors will be able to make and receive through Euroclear and Clearstream payments, deliveries, transfers and other transactions involving any beneficial interests in global securities held through those systems only on days when those systems are open for business. Those systems may not be open for business on days when banks, brokers and other institutions are open for business in the United States.

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

Due to time zone differences, the securities accounts of a participant in Euroclear or Clearstream purchasing an interest in a global security from a direct participant in DTC will be credited, and any such crediting will be reported to the relevant participant in Euroclear or Clearstream, during the securities settlement processing day (which must be a business day for Euroclear or Clearstream) immediately following the settlement date of DTC. Cash received in Euroclear or Clearstream as a result of sales of interests in a global security by or through a participant in Euroclear or Clearstream to a direct 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.
