The Notes will mature on , 2056. Interest on the Notes will accrue from and including , 2025 and will be payable semi-annually in arrears on and of each year, beginning on , 2026.

So long as no Event of Default (as defined herein) with respect to the Notes has occurred and is continuing, we may, at our option, defer interest payments on the Notes, from time to time, for one or more deferral periods of up to 20 consecutive semi-annual Interest Payment Periods (as defined herein) each. During any deferral period, interest on the Notes will continue to accrue at the then-applicable interest rate on the Notes (as reset from time to time on any Reset Date occurring during such deferral period in accordance with the terms of the Notes) and, in addition, interest on deferred interest will accrue at the then applicable interest rate on the Notes (as reset from time to time on any Reset Date occurring during such deferral period in accordance with the terms of the Notes), compounded semi-annually, to the extent permitted by applicable law. See “Description of the Notes—Option to Defer Interest Payments.”

The Notes will be fully and unconditionally guaranteed, on a joint, several and subordinated basis (the “Guarantees”), by Emera Incorporated, a Nova Scotia company (“Emera”), and Emera US Holdings Inc., a Delaware corporation (“EUSHI,” and together with Emera, the “Guarantors”). See “Description of the Notes–Guarantees.” EUSHI is a direct and indirect wholly-owned subsidiary of Emera and the Issuer is a direct, wholly-owned subsidiary of EUSHI.

The Issuer may redeem the Notes, in whole or in part at the times and the redemption prices described in this prospectus supplement under the caption “Description of the Notes—Redemption.”

The Notes and the Guarantees will be the Issuer’s and the Guarantors’ unsecured and subordinated obligations and will (a) be subordinate and rank junior in right of payment to all existing and future Senior Indebtedness (as defined in “Description of the Notes—Subordination”) of the Issuer or the relevant Guarantor, (b) rank equally in right of payment with all existing and future unsecured and subordinated indebtedness that each of the Issuer and the Guarantors may incur from time to time if the terms of such indebtedness provide that it ranks equally with the Notes and the Guarantees in right of payment, (c) be effectively subordinated to all existing and future secured indebtedness of the Issuer or the Guarantors, to the extent of the value of the assets securing such indebtedness, and (d) be structurally subordinated in right of payment to all existing and future indebtedness and other liabilities (including trade payables) of Emera’s direct and indirect subsidiaries (other than EUSHI and the Issuer). See “Description of the Notes—Subordination.” The indenture under which the Notes will be issued (the “Indenture”) contains no restrictions on the amount of Senior Indebtedness or additional secured or unsecured indebtedness the Issuer and the Guarantors may incur or the amount of indebtedness (whether secured or unsecured) that their respective subsidiaries may incur.

There is no established trading market for the Notes, and we have no plans to list the Notes on a securities exchange.

We are permitted, under a multijurisdictional disclosure system adopted by the United States and Canada, to prepare this prospectus supplement and the accompanying prospectus in accordance with Canadian disclosure requirements. Prospective investors should be aware that such requirements are different from those of the United States.

For the definitions of the terms “Reset Period,” “Five-year U.S. Treasury Rate,” “Reset Interest Determination Date” and “Reset Date” and for other important information concerning the

	calculation of interest on the Notes, see “Description of the Notes—Maturity, Interest and Payment.”

Reset Period	The period from and including the First Reset Date to but excluding the next following Reset Date and thereafter each period from and including a Reset Date to but excluding the next following Reset Date, or the maturity date or date of redemption or repayment, as the case may be.
Optional Interest Deferral	So long as no Event of Default with respect to the Notes has occurred and is continuing, the Issuer may, at its option, defer interest payments on the Notes, from time to time, for one or more deferral periods of up to 20 consecutive semi-annual Interest Payment Periods each (each such deferral period, commencing on the interest payment date on which the first such deferred interest payment otherwise would have been made, an “Optional Deferral Period”), except that no such Optional Deferral Period may extend beyond the final maturity date of the Notes or end on a day other than the day immediately preceding an interest payment date. In other words, the Issuer may declare at its discretion up to a ten-year interest payment moratorium on the Notes and may choose to do that on one or more occasions. No interest will be due or payable on the Notes during any such Optional Deferral Period unless the Issuer elects, at its option, to redeem Notes during such Optional Deferral Period, in which case accrued and unpaid interest to but excluding the redemption date will be due and payable on such redemption date only on the Notes being redeemed, or unless the principal of and interest on the Notes shall have been declared due and payable as the result of an Event of Default with respect to the Notes, in which case all accrued and unpaid interest on the Notes shall become due and payable. The Issuer may elect, at its option, to extend the length of any Optional Deferral Period that is shorter than 20 consecutive semi-annual Interest Payment Periods (so long as the entire Optional Deferral Period does not exceed 20 consecutive semi-annual Interest Payment Periods or extend beyond the final maturity date of the Notes) and to shorten the length of any Optional Deferral Period. The Issuer cannot begin a new Optional Deferral Period until the Issuer or the Guarantors have paid all accrued and unpaid interest on the Notes from any previous Optional Deferral Period. During any Optional Deferral Period, interest on the Notes will continue to accrue at the then applicable interest rate on the Notes (as reset from time to time on any Reset Date occurring during such Optional Deferral Period in accordance with the terms of the Notes). In addition,

during any Optional Deferral Period, interest on the deferred interest will accrue at the then-applicable interest rate on the Notes (as reset from time to time on any Reset Date occurring during such Optional Deferral Period in accordance with the terms of the Notes), compounded semi-annually, to the extent permitted by applicable law. For the definition of the term “Event of Default,” see “Description of the Notes—Events of Default”, and for the definition of the term “Interest Payment Period” and other important information concerning the Issuer’s right to defer interest payments on the Notes, see “Description of the Notes—Option to Defer Interest Payments.”

If the Issuer defers payments of interest on the Notes, the Notes will be treated at that time, solely for purposes of the original issue discount rules, as having been retired and reissued with original issue discount for U.S. federal income tax purposes. This means that if you are subject to U.S. federal income taxation on a net income basis, you would be required to include in your gross income for U.S. federal income tax purposes the deferred interest payments on your Notes before you receive any cash, regardless of your regular method of accounting for U.S. federal income tax purposes. For more information concerning the tax consequences you may have if payments of interest are deferred, see “Risk Factors—Holders of the Notes subject to U.S. federal income taxation may have to pay taxes on interest before they receive payments from us” and “Material U.S. Federal Income Tax Considerations—Exercise of Deferral Option.”

Additional Amounts	Subject to certain exceptions and limitations described under the heading “Description of the Notes–Additional Amounts,” the Issuer will pay such Additional Amounts (as defined herein) on the Notes as will result in the receipt by the holders of the Notes of such amounts as would have been received by them had no withholding or deduction (that is required by law) been required. For more information regarding Additional Amounts with respect to the Notes, see “Description of the Notes–Additional Amounts.”
Denominations	The Notes will be issued in minimum denominations of US$2,000 and integral multiples of US$1,000 in excess thereof.
Trustee	Equiniti Trust Company, LLC.
Governing Law	The Notes and the related Guarantees will be, and the Indenture is, governed by the laws of the State of New York.
No Listing	The Notes are a new issue of securities and no established trading market for the Notes exists. The Notes will not be listed on any automated dealer quotation system, and we do not intend to apply for listing of the Notes on any securities exchange. We have been advised that the underwriters intend to make a market in the Notes. However, they are not obligated

	to do so, and they may discontinue any market-making activities with respect to the Notes at any time without notice. No assurance can be given as to the liquidity of the trading market for the Notes or that an active public market for the Notes will develop. If an active public trading market for the Notes does not develop, the market price and liquidity of the Notes may be adversely affected.
Use of Proceeds	We estimate that the net proceeds from the offering of the Notes, after deducting the underwriting discount and our estimated offering expenses, will be approximately US$ million. We intend to use the net proceeds from this offering for general corporate purposes, including, without limitation, to repay existing indebtedness. See “Use of Proceeds” in this prospectus supplement.
Risk Factors	Investing in the Notes involves risks. See “Risk Factors” beginning on page S-9 of this prospectus supplement for a discussion of factors that you should refer to and carefully consider before deciding to invest in these Notes.

An investment in the Notes involves certain risks. A prospective purchaser of the Notes should carefully consider the risk factors set forth below as well as the other information contained in this prospectus supplement and the documents incorporated by reference herein before you decide to purchase the Notes, including, without limitation, the risk factors discussed under (i) the heading “Risk Factors” in the Emera’s Annual Information Form dated February 21, 2025 for the year ended December 31, 2024 (filed on EDGAR as Exhibit 99.1 to Emera’s Form 40-F filed February 21, 2025 and incorporated by reference herein); (ii) the heading “Principal Financial Risks and Uncertainties” in note 28 to Emera’s audited consolidated financial statements as at and for the years ended December 31, 2024 and 2023 filed on Exhibit 99.3 to Emera’s Form 40-F filed February 21, 2025; (iii) the heading “Enterprise Risk and Risk Management” in Emera’s Management’s Discussion and Analysis for the year ended December 31, 2024; and (iv) the heading “Principal Financial Risks and Uncertainties” in note 20 to Emera’s unaudited condensed consolidated interim financial statements as at and for the three and six months ended June 30, 2025 and June 30, 2024 filed on Exhibit 99.2 to Emera’s Form 6-K furnished on August 8, 2025. The risks described below are not the only risks that may affect us. Additional risks and uncertainties not currently known to us or those we currently view to be immaterial may also materially and adversely affect our business, financial condition or results of operations. Any of the following risks could materially and adversely affect our business, financial condition or results of operations. In such a case, you may lose all or a part of your investment.

Emera has a substantial amount of indebtedness which may adversely affect its cash flow and ability to operate its business.

Emera has incurred a significant amount of debt. As of June 30, 2025, Emera has approximately Cdn$20,995 million of total debt outstanding. The implications of such indebtedness include:

If new debt is added to Emera’s current debt levels, the risks that it now faces would intensify. Emera’s ability to generate sufficient cash flow from operations to make scheduled payments on its debt will depend on a range of economic, competitive and business factors, many of which are outside of its control. There can be no assurance that Emera’s business will generate sufficient cash flow from operations to make these payments, including with respect to the Notes. If Emera is unable to meet its expenses and debt obligations, Emera may need to refinance all or a portion of its indebtedness before maturity. Emera may not be able to refinance any of its indebtedness on commercially reasonable terms or at all, which could cause it to default on its obligations and impair its liquidity.

The Notes are obligations of the Issuer and the Guarantors and not of the Issuer’s or the Guarantors’ subsidiaries and will be subordinated to all other indebtedness of the Issuer and the Guarantors (other than any unsecured indebtedness the Issuer or the Guarantors may incur in the future that ranks junior to or pari passu

with the Notes) and structurally subordinated to the claims of the Issuer’s and the Guarantors’ subsidiaries’ creditors.

The Notes will be subordinated in right of payment to all of the Issuer’s and the Guarantors’ existing and future Senior Indebtedness. This means that, in the event of (a) the Issuer’s or the Guarantors’ dissolution, winding-up, liquidation or reorganization, (b) the Issuer’s or the Guarantors’ failure to pay any interest, principal or other monetary amounts due on any of its Senior Indebtedness when due (and continuance of that default beyond any applicable grace period) or (c) acceleration of the maturity of any of the Issuer’s or the Guarantors’ Senior Indebtedness as a result of a default, the Issuer will not be permitted to make any payments on the Notes until, in the case of clause (a), all amounts due or to become due on all of its Senior Indebtedness have been paid in full, or, in the case of clauses (b) and (c), all amounts due on its Senior Indebtedness have been paid in full. For additional information about the subordination of the Notes to our Senior Indebtedness, see “Description of the Notes—Subordination”

The Notes will also be structurally subordinated to any indebtedness and other liabilities of Emera’s subsidiaries (other than EUSHI and the Issuer). As of June 30, 2025, the Issuer and the Guarantors had Cdn$1,430 million of indebtedness, none of which was secured, and Emera’s subsidiaries (other than EUSHI and the Issuer) had approximately Cdn$17,245 million in indebtedness.

Due to the subordination of the Notes to the Senior Indebtedness and the effective subordination of the Notes to any secured indebtedness of the Issuer and the Guarantors, if either the Issuer’s or the Guarantors’ assets are distributed upon their respective dissolution, winding-up, liquidation or reorganization, holders of their Senior Indebtedness and any secured indebtedness would likely recover more, ratably, than the holders of the Notes, and it is possible that no payments would be made to the holders of the Notes.

The Notes will rank equally in right of payment with any existing and future unsecured and subordinated indebtedness that the Issuer or the Guarantors may incur from time to time if the terms of such indebtedness provide that it ranks equally with the Notes in right of payment.

The Issuer can defer interest payments on the Notes for one or more Optional Deferral Periods of up to 20 consecutive semi-annual Interest Payment Periods each.

So long as no Event of Default with respect to the Notes has occurred and is continuing, the Issuer may, at its option, defer interest payments on the Notes, from time to time, for one or more Optional Deferral Periods of up to 20 consecutive semi-annual Interest Payment Periods each, except that no such Optional Deferral Period may extend beyond the final maturity date of the Notes or end on a day other than the day immediately preceding an interest payment date. In other words, the Issuer may declare at its discretion up to a ten-year interest payment moratorium on the Notes and may choose to do that on one or more occasions. Moreover, following the end of any Optional Deferral Period, if all amounts then due on the Notes are paid, the Issuer could immediately start a new Optional Deferral Period of up to 20 consecutive semi-annual Interest Payment Periods. No interest will be paid or payable on the Notes during any Optional Deferral Period unless the Issuer elects, at its option, to redeem Notes during such Optional Deferral Period, in which case accrued and unpaid interest to but excluding the redemption date will be due and payable on such redemption date only on the Notes being redeemed, or unless the principal of and interest on the Notes shall have been declared due and payable as a result of an Event of Default with respect to the Notes, in which case all accrued and unpaid interest on the Notes shall become due and payable. Instead, interest on the Notes would be deferred but would continue to accrue at the then-applicable interest rate on the Notes (as reset from time to time on any Reset Date occurring during such Optional Deferral Period in accordance with the terms of the Notes). In addition, during any Optional Deferral Period, interest on the deferred interest would accrue at the then-applicable interest rate on the Notes (as reset from time to time on any Reset Date occurring during such Optional Deferral Period in accordance with the terms of the Notes), compounded semi-annually, to the extent permitted by applicable law. If the Issuer exercises this interest deferral right, the Notes may trade at a price that does not reflect the value of accrued and unpaid interest on the Notes or that is otherwise substantially less than the price at which the Notes would have traded if the Issuer had not exercised such deferral right. If the Issuer exercises this interest deferral right and you sell your Notes during an Optional Deferral Period, you may not receive the same return on your investment as a holder that continues to hold its Notes until the Issuer pays the deferred interest following the end of such Optional Deferral Period. In addition, as a result of the Issuer’s right to defer interest payments, the market price of the Notes may be more volatile than other securities that do not have these rights.

The Issuer or the Guarantors could enter into various transactions that could increase the amount of its outstanding indebtedness, or adversely affect their capital structure or credit ratings, or otherwise adversely affect holders of the Notes.

The terms of the Notes will not prevent the Issuer or the Guarantors from entering into a variety of acquisition, refinancing, recapitalization or other highly-leveraged transactions. As a result, the Issuer or the Guarantors may enter into a transaction even though the transaction could increase the total amount of their outstanding indebtedness, adversely affect their capital structure or credit ratings or otherwise adversely affect the holders of the Notes.

Each Guarantor’s Guarantee of the Notes could be voided or subordinated by applicable federal bankruptcy law and insolvency laws in the United States or Canada.

The Issuer’s obligations under the Notes will be guaranteed by the Guarantors. In the United States, under federal bankruptcy law and comparable provisions of state fraudulent transfer laws, each Guarantor’s Guarantee could be voided, or claims in respect of such Guarantee could be subordinated to all other debts of such Guarantor if, among other things, such Guarantor, at the time it incurred the indebtedness evidenced by its Guarantee, received less than reasonably equivalent value or fair consideration for the incurrence of such Guarantee; and

In addition, any payment by a Guarantor pursuant to its Guarantee could be voided and required to be returned to the Guarantor or to a fund for the benefit of the creditors of the Guarantor.

As one of the Guarantors, Emera, is organized under the laws of the province of Nova Scotia, Canada and a portion of its assets are located in Canada, applicable Canadian statutes may also allow courts to void the Notes and/or the Guarantees. The Issuer’s creditors or creditors of the Guarantors could challenge the Guarantees as fraudulent transfers, conveyances, preferences, transfers at undervalue or on other grounds under applicable Canadian federal or provincial law. Payments made to the holders of the Notes may be required to be returned or the Guarantees may be avoided or set aside under Canadian federal or provincial legislation if it is judicially determined that, among other things:

The measure of insolvency for purposes of these fraudulent transfer laws will vary depending upon the law applied in any proceeding to determine whether a fraudulent transfer has occurred. Generally, however, a guarantor would be considered insolvent if:

We cannot be sure as to the standards that a court would use to determine whether or not each Guarantor was solvent at the relevant time, or, regardless of the standard that the court uses, that the issuance of each Guarantee of the Notes would not be voided or each Guarantee of the Notes would not be subordinated to each Guarantor’s other debt.

If a Guarantee were legally challenged, such Guarantee could also be subject to the claim that, since the Guarantee was incurred for the Issuer’s benefit, and only indirectly for the benefit of the Guarantor, the obligations of the Guarantor were incurred for less than fair consideration.

A court could thus void the obligations under each Guarantee or subordinate each Guarantee to each Guarantor’s other debt or take other action detrimental to holders of the Notes.

Canadian bankruptcy and insolvency laws may impair the Trustee’s ability to enforce remedies under the Notes.

Emera is a company governed by the laws of the Province of Nova Scotia, Canada, and a portion of its assets are located in Canada. Therefore, Canadian bankruptcy and insolvency laws will apply in the event of Emera’s bankruptcy or insolvency.

Canadian bankruptcy, insolvency, winding-up, reorganization and other restructuring or similar corporate arrangement legislation (collectively, “Canadian insolvency laws”), may impair, delay, stay, compromise, or otherwise restrict the rights of the Trustee, as applicable, to enforce remedies under the Indenture governing the Notes or the Guarantees, or the Notes or the Guarantees if the benefit of applicable Canadian insolvency laws is sought with respect to Emera. For example, the Bankruptcy and Insolvency Act (Canada) and the Companies’ Creditors Arrangement Act (Canada), the Winding-Up and Restructuring Act (Canada) and other corporate arrangement legislation each contain provisions enabling a debtor to obtain a stay of proceedings or other rights and remedies in favor of itself and its property against its creditors and others and to prepare and file a restructuring proposal, a plan of arrangement or a plan of compromise or arrangement to be voted on by the various classes of its affected creditors. A restructuring proposal, plan of arrangement or plan of compromise or arrangement, as applicable, if accepted by the requisite majorities of each affected class of creditors, and if approved by the relevant Canadian court and implemented, would be binding on all affected creditors within each affected class, including those affected creditors that did not vote to accept the proposal, plan of arrangement or plan of compromise or arrangement. In addition, the relevant Canadian court may, subject to certain conditions, create court-ordered charges on the assets of the debtor to secure interim financing, professional fees, post-filing amounts owing to critical suppliers, director liabilities or other obligations, in priority to the security interests that secure the Notes and the Guarantees. Moreover, Canadian insolvency laws, in certain instances, permit the debtor (or its court appointed receiver) to retain possession and administration of its property (including property that constitutes collateral), subject to court oversight, even though it may be in default under the applicable debt instrument or security document during the applicable proceedings and notwithstanding the ability of its creditors to enforce their rights upon such default are impaired, delayed, stayed, compromised, or otherwise restricted,. In addition, it may be possible to restructure certain debt obligations, including Guarantees, under the applicable governing federal or provincial corporate statute without commencing formal insolvency proceedings.

In this regard, any approval threshold requirements provided in the Indenture governing the Notes for modification of certain rights of the holders of Notes may be disregarded in a restructuring of Emera’s debt under applicable law or the order or decree of a court having jurisdiction. In an insolvency, bankruptcy corporate arrangement in respect of a compromise of the debt of the debtors or similar proceeding, the applicable statute or the court will establish the approval threshold. The approval threshold requirements under the Indenture governing the Notes may also be disregarded in a restructuring by way of a court approved arrangement under a Canadian corporate statute. Stays of proceedings have also been granted in connection with these corporate debt restructurings.

The powers of the court under Canadian insolvency laws, and particularly the Companies’ Creditors Arrangement Act (Canada), have been interpreted and exercised broadly and remedially so as to preserve the enterprise value of a restructuring entity and protect such entity and its assets from actions taken by creditors and other parties. Accordingly, the Issuer cannot predict whether payments under the Notes or the Guarantees thereof would be made during any bankruptcy, insolvency, corporate arrangement in respect of a compromise of the debt of the debtors or other restructuring proceedings, whether (and to what extent) or when the Trustee could exercise its rights under the Indenture governing the Notes or the Guarantees during any such proceedings, or whether (and to what extent) holders of the Notes would be compensated for any delays in payment of principal, interest and costs, including the fees and

disbursements of the Trustee. Accordingly, if Emera were to become subject to any bankruptcy, insolvency, corporate arrangement in respect of a compromise of the debt of the debtors or other restructuring proceedings, Emera may cease making payments on the Guarantees and the Trustee may not be able to exercise its rights under the Indenture governing the Notes and Guarantees, respectively, following commencement of or during such proceedings, without leave of the court.

In addition, under Canadian insolvency laws, courts have jurisdiction over a debtor’s property wherever it is located, including property situated in other countries. However, courts outside of Canada may not recognize the Canadian court’s jurisdiction. Accordingly, absent recognition of the Canadian proceeding in the foreign jurisdiction, there may be difficulty administering a Canadian bankruptcy or insolvency proceeding involving the Issuer or the Guarantors in respect of property located outside of Canada, and any orders or judgments of a Canadian court may not be enforceable against the Issuer or the Guarantors with respect to their property located outside Canada.

Investors in the Notes located outside of Canada may have difficulties enforcing civil liabilities.

Emera is organized under the laws of Nova Scotia, Canada. Moreover, some of the directors and officers of Emera, EUSHI and EUSHI Finance and some of the experts named in this prospectus and documents incorporated by reference herein are non-U.S. residents, and some of Emera’s assets and some of the assets of those officers, directors and experts are located outside of the United States. We will agree, in accordance with the terms of the Indenture, to accept service of process in any suit, action or proceeding with respect to the Indenture or the Notes brought in any federal or state court located in New York City by an agent designated for such purpose, and to submit to the jurisdiction of such courts in connection with such suits, actions or proceedings. Nevertheless, it may be difficult for holders of the Notes to effect service of process within the United States upon directors, officers and experts who are not residents of the United States or to realize in the United States upon judgments of courts of the United States predicated upon civil liability under U.S. federal or state securities laws or other laws of the United States. In addition, there is doubt as to the enforceability in Canada against Emera or against Emera’s directors, officers and experts who are not residents of the United States, in original actions or in actions for enforcement of judgments of courts of the United States, of liabilities predicated solely upon U.S. federal or state securities laws.

The Issuer’s cash flow is dependent on the operating cash flows of Emera and its other subsidiaries and their ability to pay cash to the Issuer.

The Issuer’s cash flow is dependent on the operating cash flows of Emera and its subsidiaries and their ability to pay cash to the Issuer. As a result, distributions or advances from Emera and its subsidiaries are the principal source of funds necessary to meet the debt service obligations of the Issuer. Contractual provisions or laws, as well as Emera’s and its subsidiaries’ financial condition and operating requirements, may limit the ability of the Issuer to obtain cash from Emera and its subsidiaries that it requires to pay its debt service obligations, and may also limit the ability of the Guarantors to meet their obligations under their respective Guarantees, including any payments required to be made under the Notes. In addition, certain of Emera’s businesses are regulated by entities that possess broad oversight powers to ensure that the needs of utility customers are being met. While Emera is not currently aware of any plans to do so, such regulators could attempt to impose restrictions on the ability of Emera or its subsidiaries to pay cash to the Issuer pursuant to these broad powers. Other than EUSHI and the Issuer, the subsidiaries of Emera are legally distinct and have no obligations to pay amounts due on the indebtedness of the Issuer or the Guarantors, or to make funds available for such payment. In addition, non-guarantor subsidiaries of Emera will be permitted under the terms of the Indenture to incur additional indebtedness that may restrict or prohibit the making of distributions, the payment of dividends or the making of loans by such subsidiaries to the Issuer and the Guarantors. The agreements governing current and future indebtedness of Emera’s subsidiaries may not permit such subsidiaries to provide Emera with sufficient dividends, distributions or loans to fund payments on the Notes when due.

The Guarantors are holding companies and depend on dividends and other distributions from their subsidiaries. Each of Emera and EUSHI conducts substantially all its operations through subsidiaries, and those subsidiaries generate substantially all of its operating income and cash flow. As a result, distributions or advances from those subsidiaries are the principal source of funds necessary to meet the debt service obligations of the Guarantors. Contractual provisions or laws, as well as the subsidiaries’ financial condition and operating requirements, may limit the ability of the Guarantors to obtain cash from their subsidiaries that they require to pay their debt service obligations, including any payments required to be made under the Notes.

An increase in interest rates could result in a decrease in the relative value of the Notes.

In general, as market interest rates rise, Notes bearing interest at a fixed rate generally decline in value because the premium, if any, over market interest rates will decline. Consequently, if you purchase Notes and market interest rates increase, the market value of your Notes may decline. We cannot predict future levels of market interest rates.

The trading prices for the Notes will be directly affected by many factors, including our credit rating.

Credit rating agencies continually revise their ratings for companies they follow or discontinue rating companies, which could include the Issuer. Any ratings downgrade or decisions by a credit rating agency to discontinue rating us could adversely affect the trading price of the Notes, or the trading market for the Notes, to the extent a trading market for the Notes develops. The condition of the financial and credit markets and prevailing interest rates have fluctuated in the past and are likely to fluctuate in the future and any fluctuation may impact the trading price of the Notes.

We expect the Notes to be rated by “nationally recognized statistical rating organizations” within the meaning of the U.S. Securities Exchange Act of 1934, as amended (the “Exchange Act”). The Notes may in the future be rated by additional rating agencies. We cannot assure you that any rating so assigned will remain for any given period of time or that a rating will not be lowered or withdrawn entirely by a rating agency if, in that rating agency’s judgment, circumstances relating to the basis of the rating, such as adverse changes to our business, so warrant. Any lowering or withdrawal of a rating by a rating agency could reduce the liquidity or market value of the Notes.

Rating agencies may change their practices for rating the Notes, which change may affect the market price of the Notes. In addition, the Issuer may redeem the Notes if a rating agency makes certain changes in the equity credit methodology for securities such as the Notes.

The rating agencies that currently or may in the future publish a rating for the Issuer, including Moody’s Investors Service, Inc., S&P Global Ratings and Fitch Ratings, Inc., each of which is expected to publish a rating of the Notes, may, from time to time in the future, change the way they analyze securities with features similar to the Notes. This may include, for example, changes to the relationship between ratings assigned to an issuer’s senior securities and ratings assigned to subordinated securities with features similar to the Notes. If any rating agencies change their practices for rating these types of securities in the future, and the ratings of the Notes are subsequently lowered, the trading price of the Notes could be negatively affected. In addition, the Issuer may redeem the Notes, at its option, in whole but not in part, if a rating agency makes certain changes in the equity credit methodology for securities such as the Notes. See “Description of the Notes—Redemption—Redemption Following a Rating Agency Event.”

Your ability to transfer the Notes may be limited by the absence of a trading market for the Notes.

There is no established trading market for the Notes, and we have no plans to list the Notes on a securities exchange. We have been advised by each underwriter of the Notes that it presently intends to make a market for the Notes; however, no underwriter of the Notes is obligated to do so. Any market making activity, if initiated, may be discontinued at any time, for any reason, without notice. If the underwriters of the Notes cease to act as market makers for the Notes for any reason, we cannot assure you that another firm or person will make a market in such Notes. The liquidity of any market for the Notes will depend upon the number of holders of such Notes, our results of operations and financial condition, the market for similar securities, the interest of securities dealers in making a market in the Notes and other factors. An active or liquid trading market may not develop for the Notes.

The Issuer can defer interest payments on the Notes for one or more Optional Deferral Periods of up to 20 consecutive semi-annual Interest Payment Periods each. This may affect the market price of the Notes.

payable on such redemption date only on the Notes being redeemed, or unless the principal of and interest on the Notes shall have been declared due and payable as a result of an Event of Default with respect to the Notes, in which case all accrued and unpaid interest on the Notes shall become due and payable. Instead, interest on the Notes would be deferred but would continue to accrue at the then-applicable interest rate on the Notes (as reset from time to time on any Reset Date occurring during such Optional Deferral Period in accordance with the terms of the Notes). In addition, during any Optional Deferral Period, interest on the deferred interest would accrue at the then-applicable interest rate on the Notes (as reset from time to time on any Reset Date occurring during such Optional Deferral Period in accordance with the terms of the Notes), compounded semi-annually, to the extent permitted by applicable law. If the Issuer exercises this interest deferral right, the Notes may trade at a price that does not reflect the value of accrued and unpaid interest on the Notes or that is otherwise substantially less than the price at which the Notes would have traded if the Issuer had not exercised such deferral right. If the Issuer exercises this interest deferral right and you sell your Notes during an Optional Deferral Period, you may not receive the same return on your investment as a holder that continues to hold its Notes until the Issuer pays the deferred interest following the end of such Optional Deferral Period. In addition, as a result of the Issuer’s right to defer interest payments, the market price of the Notes may be more volatile than other securities that do not have these rights.

Holders of the Notes subject to U.S. federal income taxation may have to pay taxes on interest before they receive payments from us.

If the Issuer defers interest payments on the Notes, a holder of the Notes subject to U.S. federal income tax on a net income basis will be required to accrue interest income for U.S. federal income tax purposes in respect of such holder’s proportionate share of the accrued but unpaid interest on the Notes, even if such holder normally reports income when received. As a result, a holder will be required to include the accrued interest in such holder’s gross income for U.S. federal income tax purposes even though such holder will not have received any cash. A holder’s adjusted tax basis in a Note generally will be increased by such amounts that it was required to include in gross income. In addition, unpaid interest accrued on the Notes during an Optional Deferral Period will be payable on the interest payment date immediately following the last day of such Optional Deferral Period. If a holder sells its Notes on or before the record date for such interest payment date, then all of the interest accrued on such Notes during the Optional Deferral Period will be paid to the person who is the registered owner of those Notes at the close of business on such record date, and the holder who sold those Notes will not receive from the Issuer any of the interest that accrued on those Notes during the Optional Deferral Period and that such holder reported as income for tax purposes. Holders should consult with their tax advisors regarding the tax consequences of an investment in the Notes. For more information regarding the tax consequences of purchasing, owning and disposing of the Notes, see “Material Income Tax Considerations.”

The Issuer may at its option redeem the Notes in whole or in part at the times and the applicable redemption price described herein. See “Description of the Notes—Redemption.” The Issuer may choose to redeem your Notes at a time when prevailing interest rates are lower than the interest rate paid on your Notes. If prevailing interest rates are lower at the time of redemption, you may not be able to reinvest the redemption proceeds in a comparable security at an effective interest rate as high as the interest rate of the Notes being redeemed.

The historical Five-year U.S. Treasury Rates are not an indication of future Five-year U.S. Treasury Rates.

The annual interest rate on the Notes for each Reset Period will be set by reference to the Five-year U.S. Treasury Rate as of the most recent Reset Interest Determination Date (provided, that the interest rate during any Reset Period will not reset below the initial interest rate). In the past, U.S. Treasury rates have experienced significant fluctuations. You should note that historical levels, fluctuations and trends of U.S. Treasury rates are not necessarily indicative of future levels. Any historical upward or downward trend in U.S. Treasury rates is not an indication that U.S. Treasury rates are more or less likely to increase or decrease at any time in the future and you should not take historical U.S. Treasury rates as an indication of future U.S. treasury Rates.

While it is not possible for the interest rate on the Notes to decrease below the initial interest rate, the interest rate on the Notes may fluctuate over time.

While it is not possible for the interest rate on the Notes to decrease below the initial interest rate, the interest rate for a given Reset Period subsequent to the initial Reset Period may decrease as compared to the interest rate for the

prior Reset Period. We have no control over the factors that may affect U.S. Treasury rates, including geopolitical, economic, financial, political, regulatory, judicial or other conditions or events.

As of June 30, 2025, Emera had US$2.95 billion (as of December 31, 2024 – US$2.95 billion) senior unsecured notes issued by Emera US Finance LP and junior subordinated notes issued by EUSHI Finance (collectively referred to as the “US Notes”) outstanding.

The US Notes are fully and unconditionally guaranteed, on a joint and several basis, and in the case of the fixed-to-fixed reset rate junior subordinated notes due 2054 only, on a joint, several and subordinated basis, by Emera and EUSHI (in such capacity, the “Guarantor Subsidiaries”). Emera owns, directly or indirectly, all of the limited and general partnership interests in Emera US Finance LP. EUSHI Finance is owned indirectly by Emera through EUSHI. Other subsidiaries of Emera do not guarantee the US Notes (such subsidiaries are referred to as the “Non-Guarantor Subsidiaries”); however, Emera has unrestricted access to the assets of consolidated entities. In compliance with Rule 13-01 of Regulation S-X, Emera is including summarized financial information for Emera, EUSHI and EUSHI Finance (together, the “Obligor Group”), on a combined basis after transactions and balances between the combined entities have been eliminated. Investments in and equity earnings of the Non-Guarantor Subsidiaries have been excluded from the summarized financial information.

The Obligor Group was not determined using geographic, service line or other similar criteria and, as a result, the summarized financial information includes portions of Emera’s domestic and international operations. Accordingly, this basis of presentation is not intended to present Emera’s financial condition or results of operations for any purpose other than to comply with the specific requirements for guarantor reporting.

We estimate that the net proceeds from this offering of the Notes, after deducting the underwriting discount and our estimated offering expenses, will be approximately US$ million. We intend to use the net proceeds from this offering for general corporate purposes, including, without limitation, to repay existing indebtedness. We may invest funds that we do not immediately use in short-term marketable securities.

As used below, the terms (i) “we,” “our,” and “us” refer to Emera Incorporated, EUSHI Finance, Inc., Emera US Holdings Inc., and, if the context requires, Emera Incorporated’s subsidiaries, (ii) “Emera” refers to Emera Incorporated and, if the context requires, its subsidiaries, (iii) the “Issuer” refers to EUSHI Finance, Inc., (iv) the “Guarantors” refers collectively to Emera Incorporated and Emera US Holdings Inc., and (v) “EUSHI” refers to Emera US Holdings Inc.

We are offering US$ % Fixed-to-Fixed Reset Rate Junior Subordinated Notes due 2056 (the “Notes”), which will be registered under the Securities Act of 1933, as amended (the “Securities Act”).

The Notes will be issued, under an indenture dated as of June 18, 2024 as to be amended and supplemented by a supplemental indenture (collectively, the “Indenture”), among us, the Guarantors and Equiniti Trust Company, LLC, as trustee (the “Trustee”). The Notes will be fully and unconditionally guaranteed, on a joint, several and subordinated basis, by the Guarantors (the “Guarantees”). The Indenture is subject to the Trust Indenture Act of 1939, as amended (the “Trust Indenture Act”). The terms of the Notes will include those expressly set forth in the Indenture and those made part of the Indenture by reference to the Trust Indenture Act.

The following description of the particular terms and provisions on the Notes and the Guarantees, supplements and, to the extent inconsistent therewith, replaces the description of the Debt Securities and the guarantees set forth in the accompanying prospectus under “Description of the Debt Securities and Guarantees” to which reference is made.

This description of the Notes is intended to be a useful overview of the material provisions of the Notes, the Guarantees and the Indenture. Since this description is only a summary, you should refer to the Indenture, a copy of which is available from us upon request, for a complete description of the obligations of the Issuer and the Guarantors and your rights. We urge you to read the Indenture carefully because it, and not the following description, will govern your rights as a holder of the Notes.

The Notes will mature on , 2056, subject to earlier redemption at the Issuer’s option as described under “—Redemption.”

The Notes will bear interest (i) from and including , 2025 (the “original issue date”) to but excluding , 2031 (the “First Reset Date”), at the rate of % per annum and (ii) from and including the First Reset Date, during each Reset Period (as defined below) at a rate per annum equal to the Five-year U.S. Treasury Rate (as defined below) as of the most recent Reset Interest Determination Date (as defined below), plus a spread of % to be reset on each Reset Date (as defined below); provided, that the interest rate during any Reset Period will not reset below % (which equals the initial interest rate on the Notes). Interest on the Notes will accrue from the original issue date and will be payable semi-annually in arrears on and (each, an “interest payment date”) of each year until maturity or earlier redemption, beginning on , 2026, to the holders of record at the close of business on the record date for the applicable interest payment date, which will be (i) the business day immediately preceding such interest payment date so long as all of the Notes remain in book-entry only form or (ii) the 15th calendar day preceding such interest payment (whether or not a business day) if any of the Notes do not remain in book-entry only form (each, a “record date”), subject to our right to defer interest payments as described below under “—Option to Defer Interest Payments.” Interest on the Notes will be computed on the basis of a 360-day year of twelve 30-day months.

The applicable interest rate for each Reset Period will be determined by the calculation agent (as defined below), as of the applicable Reset Interest Determination Date, in accordance with the following provisions:

“Five-year U.S. Treasury Rate” means, as of any Reset Interest Determination Date, (i) an interest rate (expressed as a decimal) determined to be the per annum rate equal to the arithmetic mean of the yields to maturity for U.S. Treasury securities adjusted to constant maturity with a maturity of five years from the next Reset Date and trading in the public securities markets, for the five consecutive business days immediately prior to the respective Reset Interest Determination Date as published (or, if fewer than five consecutive business days are so published on the applicable Reset Interest Determination Date, for such number of business days published) in the most recent H.15, or (ii) if there is no such published U.S. Treasury security with a maturity of five years from the next Reset Date and trading in the

public securities markets, then the rate will be determined by interpolation between the arithmetic mean of the yields to maturity for each of the two series of U.S. Treasury securities adjusted to constant maturity trading in the public securities markets, (A) one maturing as close as possible to, but earlier than, the Reset Date following the next succeeding Reset Interest Determination Date, and (B) the other maturing as close as possible to, but later than, the Reset Date following the next succeeding Reset Interest Determination Date, in each case for the five consecutive business days immediately prior to the respective Reset Interest Determination Date as published (or, if fewer than five consecutive business days are so published on the applicable Reset Interest Determination Date, for such number of business days published) in the most recent H.15. If the Five-year U.S. Treasury Rate cannot be determined pursuant to the methods described in clause (i) or (ii) above, then the Five-year U.S. Treasury Rate will be the same interest rate determined for the prior Reset Interest Determination Date or, if the Five-year U.S. Treasury Rate cannot be so determined as of the Reset Interest Determination Date preceding the First Reset Date, then the interest rate applicable for the Reset Period beginning on and including the First Reset Date will be deemed to be % per annum, which is the same interest rate as in effect from and including the original issue date to but excluding the First Reset Date.

“H.15” means the statistical release designated as such, or any successor publication, published by the Board of Governors of the U.S. Federal Reserve System (or any successor thereto).

The “most recent H.15” means the H.15 published closest in time but prior to the close of business on the second business day prior to the applicable Reset Date.

“Reset Interest Determination Date” means, in respect of any Reset Period, the day falling two business days prior to the first day of such Reset Period.

“Reset Period” means the period from and including the First Reset Date to but excluding the next following Reset Date and thereafter each period from and including a Reset Date to but excluding the next following Reset Date, or the maturity date or date of redemption or repayment, as the case may be.

As used under this caption “Description of the Notes,” the term “business day” means, unless otherwise expressly stated, any day other than (i) a Saturday or Sunday or (ii) a day on which banks and trust companies in The City of New York are authorized or obligated by law, regulation or executive order to remain closed.

The term “calculation agent” means, at any time, the entity appointed by the Issuer and serving as such agent with respect to the Notes at such time. Unless the Issuer has validly called all of the outstanding Notes for redemption on a redemption date occurring prior to the First Reset Date, the Issuer will appoint a calculation agent for the Notes prior to the Reset Interest Determination Date immediately preceding the First Reset Date; provided that, if the Issuer has called all of the outstanding Notes for redemption on a redemption date occurring prior to the First Reset Date but the Issuer does not redeem all of the outstanding Notes on such redemption date, the Issuer will appoint a calculation agent for the Notes as promptly as practicable after such proposed redemption date. The Issuer may terminate any such appointment and may appoint a successor calculation agent at any time and from time to time (so long as there shall always be a calculation agent in respect of the Notes when so required). The Issuer may appoint Emera or an affiliate of Emera as calculation agent.

As provided above, the applicable interest rate for each Reset Period will be determined by the calculation agent as of the applicable Reset Interest Determination Date. Promptly upon such determination, the calculation agent will notify us of the interest rate for the Reset Period and the Issuer will promptly notify, or cause the calculation agent to promptly notify, the Trustee and each paying agent of such interest rate. The calculation agent’s determination of any interest rate, and its calculation of the amount of interest for any Interest Payment Period (as defined below under “—Option to Defer Interest Payments”) beginning on or after the First Reset Date, will be on file at the Issuer’s principal offices, will be made available to any holder or beneficial owner of the Notes upon request and will be final and binding in the absence of manifest error.

If an interest payment date, redemption date, or maturity date falls on a day that is not a business day, payment will be made on the next succeeding business day with the same force and effect as if made on such payment date.

The Notes are a new issue of securities with no established trading market. The Issuer does not intend to apply for the listing or trading of the Notes on any securities exchange or trading facility or for inclusion of the Notes in any automated quotation system.

Each holder (and beneficial owner) of the Notes will, by accepting any Notes (or a beneficial interest therein), be deemed to have agreed to treat the Notes as indebtedness and interest thereon as U.S. source, and will treat the Notes and interest accordingly, for U.S. federal, state and local tax purposes. For a discussion of the tax treatment of the Notes, see “Material U.S. Federal Income Tax Considerations.”

Each Guarantor will fully and unconditionally guarantee, on a joint, several and subordinated basis, the due and punctual payment of the principal of, premium, if any, and interest on the Notes and any other obligations of the Issuer under the Notes when and as they become due and payable, whether at stated maturity, upon redemption (including with respect to a Tax Event or a Rating Agency Event), by acceleration or otherwise if the Issuer is unable to satisfy these obligations.

Emera is a holding company and conducts substantially all of its business through its direct and indirect operating subsidiaries. EUSHI, a direct and indirect wholly owned subsidiary of Emera, serves as a holding company for Emera’s current assets located in the United States. The principal sources of income of Emera and EUSHI are the dividends and distributions they receive from their subsidiaries.

The Guarantees will be the joint, several and subordinated obligations exclusively of Emera and EUSHI and will rank junior and subordinated in right of payment to the prior payment in full of the Guarantor’s Senior Indebtedness. Furthermore, none of Emera’s direct and indirect subsidiaries (other than EUSHI) will guarantee or otherwise be responsible for the payment of principal of, any premium or interest or other payments required to be made by the Guarantors under the Guarantees. Accordingly, obligations of the Guarantors under the Guarantees will be structurally subordinated to all existing and future indebtedness and other liabilities (including trade payables) of Emera’s direct and indirect subsidiaries (other than EUSHI).

The Indenture provides that upon a default in payment of principal or any premium or interest on a Note, the holder of the Notes may institute legal proceedings directly against the Guarantors to enforce the Guarantees without first proceeding against the Issuer. The obligations of each Guarantor under the Guarantees will be limited as necessary to prevent such Guarantees from constituting a fraudulent conveyance or fraudulent transfer under applicable law.

The payment of the principal of, premium, if any, and interest on the Notes and the payment of the Guarantees will:

The Notes and the Guarantees will be subordinated in right of payment to the prior payment in full of all Senior Indebtedness. This means that upon:

“Senior Indebtedness” means, with respect to the Notes and the Guarantees, (i) indebtedness of the Issuer or the Guarantors, whether outstanding at the date of the Indenture or incurred, created or assumed after such date, (a) in respect of money borrowed by the Issuer or the Guarantors (including any financial derivative, hedging or futures contract or similar instrument, to the extent any such item is primarily a financing transaction) and (b) evidenced by debentures, bonds, notes, credit or loan agreements or other similar instruments or agreements issued or entered into by the Issuer or the Guarantors; (ii) all finance lease obligations of the Issuer or the Guarantors; (iii) all obligations of the Issuer or the Guarantors issued or assumed as the deferred purchase price of property, all conditional sale obligations of the Issuer or the Guarantors and all obligations of the Issuer or the Guarantors under any title retention agreement (but excluding, for the avoidance of doubt, trade accounts payable arising in the ordinary course of business and long-term purchase obligations); (iv) all obligations of the Issuer or the Guarantors for the reimbursement of any letter of credit, banker’s acceptance, security purchase facility or similar credit transaction; and (v) all obligations of the type referred to in clauses (i) through (iv) above of other persons for the payment of which the Issuer or the Guarantors are responsible or liable as obligor, guarantor or otherwise, except for any obligations, instruments or agreements of the type referred to in any of clauses (i) through (v) above that, by the terms of the instruments or agreements creating or evidencing the same or pursuant to which the same is outstanding, are subordinated or equal in right of payment to each of the Notes and the Guarantees. As of June 30, 2025, the Issuer and the Guarantors had approximately Cdn$1,430 million of indebtedness, none of which was secured, and Cdn$2,320 million of which was subordinated. As of June 30, 2025 Emera’s subsidiaries (other than EUSHI and the Issuer) had approximately Cdn$17,245 million in indebtedness.

In the event of an insolvency, liquidation or other reorganization of any of Emera’s subsidiaries (other than EUSHI and the Issuer), the creditors of such subsidiaries would generally be entitled to payment in full from such assets before any assets are made available for distribution to the Guarantors.

Due to the subordination of the Notes and the Guarantees, if assets of the Issuer or the Guarantors are distributed upon their respective dissolution, winding-up, liquidation or reorganization, holders of their Senior Indebtedness and other indebtedness and obligations that are not equal or junior to each of the Notes and the Guarantees in right of payment will likely recover more, ratably, than holders of the Notes and the Guarantees, and it is possible that no payments will be made to the holders of the Notes and the Guarantees.

None of the Notes, the Guarantees or the Indenture will limit the amount of indebtedness, including Senior Indebtedness, that the Issuer and the Guarantors may issue, guarantee or otherwise incur or the amount of liabilities, including debt or preferred stock, that the Issuer, the Guarantors' and their respective subsidiaries may issue, guarantee or otherwise incur.

So long as no Event of Default (as defined below under “—Events of Default”) with respect to the Notes has occurred and is continuing, the Issuer may, at its option, defer interest payments on the Notes, from time to time, for one or more deferral periods of up to 20 consecutive semi-annual Interest Payment Periods (as defined below) (each such deferral period, commencing on the interest payment date on which the first such deferred interest payment otherwise would have been made, an “Optional Deferral Period”), except that no such Optional Deferral Period may extend beyond the final maturity date of the Notes or end on a day other than the day immediately preceding an interest payment date. During any Optional Deferral Period, interest on the Notes will continue to accrue at the then-applicable interest rate on the Notes (as reset from time to time on any Reset Date occurring during such Optional Deferral Period in accordance with the terms of the Notes). In addition, during any Optional Deferral Period, interest on the deferred interest (“compound interest”) will accrue at the then-applicable interest rate on the Notes (as reset from time to time on any Reset Date occurring during such Optional Deferral Period in accordance with the terms of the Notes), compounded semi-annually, to the extent permitted by applicable law. No interest will be due or payable on the Notes during an Optional Deferral Period, except upon a redemption of any Notes on any redemption date during such Optional Deferral Period (in which case all accrued and unpaid interest (including, to the extent permitted by applicable law, any compound interest) on the Notes to be redeemed to but excluding such redemption date will be due and payable on such redemption date), or unless the principal of and interest on the Notes shall have been declared due and payable as the result of an Event of Default with respect to the Notes (in which case all accrued and unpaid interest, including, to the extent permitted by applicable law, any compound interest, on the Notes shall become due and payable). All references in the Notes and, insofar as relates to the Notes, the Indenture, to “interest” on the Notes shall be deemed to include any such deferred interest and, to the extent permitted by applicable law, any compound interest, unless otherwise expressly stated or the context otherwise requires.

Before the end of any Optional Deferral Period that is shorter than 20 consecutive semi-annual Interest Payment Periods, the Issuer may elect, at its option, to extend such Optional Deferral Period, so long as the entire Optional Deferral Period does not exceed 20 consecutive semi-annual Interest Payment Periods or extend beyond the final maturity date of the Notes. The Issuer may also elect, at its option, to shorten the length of any Optional Deferral Period. No Optional Deferral Period (including as extended or shortened) may end on a day other than the day immediately preceding an interest payment date. At the end of any Optional Deferral Period, if all amounts then due on the Notes, including all accrued and unpaid interest thereon (including, without limitation and to the extent permitted by applicable law, any compound interest), are paid, the Issuer may elect to begin a new Optional Deferral Period; provided, however, that, without limitation of the foregoing, the Issuer may not begin a new Optional Deferral Period unless the Issuer has paid all accrued and unpaid interest on the Notes (including, without limitation and to the extent permitted by applicable law, any compound interest) from any previous Optional Deferral Periods.

During any Optional Deferral Period, the Issuer and the Guarantors will not do any of the following (subject to the exceptions set forth in the next succeeding paragraph):

However, during an Optional Deferral Period, the Issuer and the Guarantors may (a) declare and pay dividends or distributions payable solely in shares of Emera’s or the Issuer’s common stock (together, for the avoidance of doubt, with cash in lieu of any fractional share) or options, warrants or rights to subscribe for or purchase shares of the

Emera’s or the Issuer’s common stock, (b) declare and pay any dividend in connection with the implementation of a plan (a “Rights Plan”) providing for the issuance by Emera or the Issuer to all holders of Emera’s or the Issuer’s common stock of rights entitling them to subscribe for or purchase common stock or any class or series of Emera’s or the Issuer’s preferred stock, which rights (1) are deemed to be transferred with such common stock, (2) are not exercisable until the occurrence of a specified event or events and (3) are also issued in respect of future issuances of Emera’s or the Issuer’s common stock, (c) issue any of shares Emera’s or the Issuer’s Capital Stock under any Rights Plan or redeem or repurchase any rights distributed pursuant to a Rights Plan, (d) reclassify Emera’s or the Issuer’s Capital Stock or exchange or convert one class or series of Emera’s or the Issuer’s’ Capital Stock for another class or series of Emera’s or the Issuer’s’ Capital Stock, (e) purchase fractional interests in shares of Emera’s or the Issuer’s Capital Stock pursuant to the conversion or exchange provisions of such Capital Stock or the security being converted or exchanged, (f) purchase, acquire or withhold shares of Emera’s or the Issuer’s common stock related to the issuance of Emera’s or the Issuer’s common stock or rights under any dividend reinvestment plan or related to any of Emera’s or the Issuer’s benefit plans for Emera’s and the Issuer’s directors, officers, employees, consultants or advisors, including any employment contract, and (g) for the avoidance of doubt, convert convertible Capital Stock of Emera’s or the Issuer’s into other Capital Stock of Emera or the Issuer in accordance with the terms of such convertible Capital Stock (together, for the avoidance of doubt, with cash in lieu of any fractional share).

Notwithstanding the foregoing, the Indenture does not restrict in any manner the ability of any of Emera’s subsidiaries (other than the Issuer) to pay dividends or make any distributions to Emera or to any of Emera’s other subsidiaries.

The Issuer will give the holders of the Notes and the Trustee notice of its election of, or any shortening or extension of, an Optional Deferral Period at least 10 business days prior to the earlier of (1) the next succeeding interest payment date or (2) the date upon which the Issuer is required to give notice to any applicable self-regulatory organization or to holders of the Notes of the next succeeding interest payment date or the record date therefor. The record date for the payment of deferred interest and, to the extent permitted by applicable law, any compound interest payable on the interest payment date immediately following the last day of an Optional Deferral Period will be the regular record date with respect to such interest payment date.

“Capital Stock” means (i) in the case of a corporation or a company, corporate stock or shares; (ii) in the case of an association or business entity, any and all shares, interests, participations, rights or other equivalents (however designated) of corporate stock; (iii) in the case of a partnership or limited liability company, partnership or membership interests (whether general or limited); and (iv) any other interest or participation that confers on a person the right to receive a share of the profits and losses of, or distributions of assets of, the issuing person.

“Interest Payment Period” means the semi-annual period from and including an interest payment date to but excluding the next succeeding interest payment date, except for the first Interest Payment Period which shall be the period from and including the original issue date to but excluding , 2026.

The Issuer may redeem some or all of the Notes, at its option, in whole or in part (i) on any day in the period commencing on the date falling 90 days prior to the First Reset Date and ending on and including the First Reset Date and (ii) after the First Reset Date, on any interest payment date, at a redemption price in cash equal to 100% of the principal amount of the Notes being redeemed, plus, subject to the terms described in the first paragraph under “—Redemption Procedures; Cancellation of Redemption” below, accrued and unpaid interest on the Notes to be redeemed to but excluding the redemption date.

The Issuer may at its option redeem the Notes, in whole but not in part, at any time following the occurrence and during the continuance of a Tax Event (as defined below) at a redemption price in cash equal to 100% of the principal amount of the Notes, plus, subject to the terms described in the first paragraph under “—Redemption Procedures; Cancellation of Redemption” below, accrued and unpaid interest on the Notes to but excluding the redemption date.

A “Tax Event” means that the Issuer has received an opinion of counsel experienced in such matters to the effect that, as a result of:

which amendment, clarification or change is effective or the administrative action is taken or judicial decision, interpretation or pronouncement is issued or threatened challenge is asserted or becomes publicly-known after the date of this prospectus supplement, there is more than an insubstantial risk that interest payable by the Issuer on the Notes is not deductible, or within 90 days would not be deductible, in whole or in part, by the Issuer (or a member of the U.S. consolidated group of which the issuer is a member) for U.S. federal income tax purposes.

The Issuer may at its option redeem the Notes, in whole but not in part, at any time following the occurrence and during the continuance of a Rating Agency Event (as defined below) at a redemption price in cash equal to 102% of the principal amount of the Notes, plus, subject to the terms described in the first paragraph under “—Redemption Procedures; Cancellation of Redemption” below, accrued and unpaid interest on the Notes to but excluding the redemption date.

“Rating Agency Event” means, as of any date, a change, clarification or amendment in the methodology published by any nationally recognized statistical rating organization within the meaning of Section 3(a)(62) of the Exchange Act (or any successor provision thereto), that then publishes a rating for the Issuer (together with any successor thereto, a “rating agency”) in assigning equity credit to securities such as the Notes, (a) as such methodology was in effect on the date of this prospectus supplement, in the case of any rating agency that published a rating for the Issuer as of the date of this prospectus supplement, or (b) as such methodology was in effect on the date such rating agency first published a rating for the Issuer, in the case of any rating agency that first publishes a rating for the Issuer after the date of this prospectus supplement (in the case of either clause (a) or (b), the “current methodology”), that results in (i) any shortening of the length of time for which a particular level of equity credit pertaining to the Notes by such rating agency would have been in effect had the current methodology not been changed or (ii) a lower equity credit (including up to a lesser amount) being assigned by such rating agency to the Notes as of the date of such change, clarification or amendment than the equity credit that would have been assigned to the Notes by such rating agency had the current methodology not been changed.

Notwithstanding any statement under this caption “—Redemption” to the contrary, installments of interest on the Notes that are due and payable on any interest payment date falling on or prior to a redemption date for the Notes will be payable on that interest payment date to the registered holders thereof as of the close of business on the relevant record date according to the terms of the Notes and the Indenture, except that, if the redemption date for any Notes falls on any day during an Optional Deferral Period (as defined below under “—Option to Defer Interest Payments”), accrued and unpaid interest (including, to the extent permitted by applicable law, any compound interest (as defined below under “—Option to Defer Interest Payments”)) on such Notes will be paid on such redemption date to the persons entitled to receive the redemption price of such Notes. For the avoidance of doubt, the interest payment date

falling immediately after the last day of an Optional Deferral Period shall not be deemed to fall on a day during such Optional Deferral Period.

Notice of any redemption will be mailed or electronically delivered (or otherwise transmitted in accordance with the depositary’s procedures) at least 10 days but not more than 60 days before the redemption date to each holder of Notes to be redeemed. Once notice of redemption is mailed, the Notes called for redemption will become due and payable on the redemption date at the applicable redemption price, plus, subject to the terms described in the immediately preceding paragraph, accrued and unpaid interest to but excluding the redemption date, and will be paid upon surrender thereof for redemption, unless (a) the notice of redemption provides that such redemption shall be subject to the condition described in the next succeeding paragraph and (b) such redemption shall have been canceled in accordance with the provisions of the next succeeding paragraph because such condition shall not have been satisfied. If only part of a note is redeemed, the Trustee will issue in the name of the registered holder of the note and deliver to such holder a new note in a principal amount equal to the unredeemed portion of the principal of the note surrendered for redemption. If the Issuer elects to redeem all or a portion of the Notes, then, unless otherwise provided in such notice of redemption as described in the next succeeding paragraph, the redemption will not be conditional upon receipt by the paying agent or the Trustee of monies sufficient to pay the redemption price.

If, at the time a notice of redemption is given, (i) the Issuer has not effected satisfaction and discharge of the Notes as described under “—Satisfaction and Discharge” and (ii) such notice of redemption is not being given in connection with or in order to effect satisfaction and discharge of the Notes, then, if the notice of redemption so provides and at our option, the redemption may be subject to the condition that the Trustee shall have received, on or before the applicable redemption date, monies in an amount sufficient to pay the redemption price and accrued and unpaid interest on the Notes called for redemption to but excluding the redemption date. If monies in such amount are not received by the Trustee on or before such redemption date, such notice of redemption shall be automatically canceled and of no force or effect, such proposed redemption shall be automatically canceled and the Issuer shall not be required to redeem the Notes called for redemption on such redemption date. In the event that a redemption is canceled, the Issuer will, not later than the business day immediately following the proposed redemption date, deliver, or cause to be delivered, notice of such cancellation to the registered holders of the Notes called for redemption (which notice will also indicate that any Notes or portions thereof surrendered for redemption shall be returned to the applicable holders), and the Issuer will direct the Trustee to, and the Trustee will, promptly return any Notes or portions thereof that have been surrendered for redemption to the applicable holders.

Unless the Issuer or the Guarantor defaults in payment of the redemption price or the proposed redemption is canceled in accordance with the provisions set forth in the immediately preceding paragraph, on and after the redemption date interest will cease to accrue on the Notes or portions thereof called for redemption.

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

The Trustee shall have no duty to determine, or verify the calculation of, the redemption price.

If the Issuer redeems less than all of the Notes on any redemption date, the Trustee will select the Notes to be redeemed by lot or, in the case of Notes in book-entry form represented by one or more global Notes, by such other customary method prescribed by the depositary, which may be made on a pro rata pass-through distribution of principal basis.

Unless the Issuer or the Guarantors default in payment of the redemption price, on and after the redemption date interest will cease to accrue on the Notes or portions thereof called for redemption.

All payments made by or on behalf of Emera, EUSHI or the Issuer under or with respect to the Notes or the Guarantees will be made free and clear of and without withholding or deduction for or on account of any present or future tax, duty, levy, impost, assessment or other governmental charge imposed or levied by or on behalf of the Government of Canada or any province or territory thereof or by any authority or agency therein or thereof having power to tax (“Canadian Taxes”), unless Emera, EUSHI or the Issuer, as the case may be, is required to withhold or deduct Canadian Taxes by law or by the interpretation or administration thereof. If Emera, EUSHI or the Issuer, as the case may be, is so required to withhold or deduct any amount for or on account of Canadian Taxes from any

payment made under or with respect to the Notes or the Guarantees, Emera, EUSHI or the Issuer, as the case may be, will pay to each holder of such Notes as additional interest such additional amounts (“Additional Amounts”) as may be necessary so that the net amount received by each such holder after such withholding or deduction (and after deducting any Canadian Taxes on such Additional Amounts) will not be less than the amount such holder would have received if such Canadian Taxes had not been withheld or deducted. However, no Additional Amounts will be payable with respect to a payment made to a recipient or beneficial owner of such payment:

The Issuer will also (i) make such withholding or deduction and (ii) remit the full amount deducted or withheld to the relevant authority in accordance with applicable law. Notwithstanding the foregoing, Emera, EUSHI or the Issuer, as the case may be, will indemnify and hold harmless the recipient of any payment made under the Notes or any Guarantee for the amount of any taxes under Regulation 803 of the Tax Act or any similar or successor provision (other than taxes described in clauses (i) through (viii) above or taxes arising by reason of a transfer of the Note to a person resident in Canada with whom the transferor does not deal at arm’s length for the purposes of the Tax Act except where such non-arm’s length relationship arises as a result of the exercise or enforcement of rights under any Notes or any Guarantee) levied or imposed on and paid by such recipient as a result of such payment.

The Issuer will furnish to the holders of the Notes within 60 days after the date the payment of any Canadian Taxes is due pursuant to applicable law, certified copies of tax receipts or other documents evidencing such payment by the Issuer.

In the event the Issuer fails to remit any Canadian Taxes in respect of which Additional Amounts are payable, the Issuer will indemnify and hold harmless each holder of Notes (other than, for certainty, a recipient or beneficial owner not entitled to receive Additional Amounts) and upon written request reimburse each such holder for the amount, excluding any payment of Additional Amounts by the Issuer, of

Wherever in the Indenture there is mentioned, in any context, the payment of principal, premium, if any, interest or any other amount payable under or with respect to the Notes or the Guarantees, such mention shall be deemed to include mention of the payment of Additional Amounts to the extent that, in such context, Additional Amounts are, were or would be payable in respect thereof.

The Indenture provides, with respect to the Notes, that any of the following events constitutes an Event of Default:

No Event of Default with respect to the Notes will necessarily constitute an Event of Default with respect to the subordinated debt securities of any other series that may be issued under the Indenture, and no Event of Default with respect to any such other series of subordinated debt securities that may be issued under the Indenture will necessarily constitute an Event of Default with respect to the Notes.

If an Event of Default (other than one described in clause (5) above) occurs and is continuing with respect to the Notes, either the Trustee or the holders of at least 25% in principal amount of the outstanding Notes may declare the principal of, premium, if any, and accrued and unpaid interest (including, without limitation, any deferred interest and, to the extent permitted by applicable law, any compound interest) on the Notes to be due and payable immediately (notwithstanding any deferral of interest payments in accordance with the provisions discussed above under “—Option to Defer Interest Payments”). If any Event of Default described in clause (5) above occurs, the principal of, premium, if any, and accrued and unpaid interest (including, without limitation, any deferred interest and, to the extent permitted by applicable law, any compound interest) on the Notes will be automatically due and payable immediately (notwithstanding any deferral of interest payments in accordance with the provisions discussed above under “—Option to Defer Interest Payments”), without any declaration, notice or other act on the part of the Trustee or any holder. However, any time after an acceleration with respect to the Notes has occurred, but before a judgment or decree based on such acceleration has been obtained, the holders of a majority in principal amount of outstanding Notes may, under some circumstances, rescind and annul such acceleration. The majority-holders, however, may not annul or waive a continuing default in payment of principal of, premium, if any, or interest on the Notes.

The Trustee will be entitled to receive reasonable indemnification satisfactory to it from the holders of the Notes before the Trustee exercises any of its rights or powers under the Indenture. This indemnification is subject to the Trustee’s duty to act with the required standard of care during a default.

The holders of a majority in principal amount of the outstanding Notes may direct the time, method and place of:

This right of the holders of the Notes is, however, subject to the provisions in the Indenture providing for the indemnification of the Trustee and other specified limitations. In general, the holders of Notes may institute an action against the Issuer or the Guarantors or any other obligor under the Notes only if the following four conditions are fulfilled:

The above four conditions do not apply to actions by holders of the Notes against the Issuer or the Guarantors or any other obligor under the Notes for payment of principal of, premium, if any, or interest on or after the due date.

The Indenture contains a covenant that the Issuer, the Guarantors and any other obligor under the Notes will file annually with the Trustee a statement by an officer as to whether or not the Issuer or the Guarantors, as the case may be, to his or her knowledge, is in default in the performance or observance of any of the terms, provisions and conditions of the Indenture and, if so, specifying all such known defaults, provided, however, that a failure to deliver such statement of a default shall not constitute a default under the Indenture, if such default is remedied within any applicable cure period.

The Indenture limits the ability of the Issuer and the Guarantors to enter into mergers, consolidations or transfers of all of their respective assets. Accordingly, neither the Issuer nor the Guarantors are permitted to consolidate or merge with any other entity or convey, transfer or lease all or substantially all of its assets or properties to any entity unless:

Regardless of whether Emera is subject to the reporting requirements of Section 13 or 15(d) of the Exchange Act or otherwise reports on an annual and quarterly basis on forms provided for such annual and quarterly reporting pursuant to rules and regulations promulgated by the SEC, the Indenture requires Emera to provide to the Trustee:

regardless of applicable requirements shall, at a minimum, contain such information required to be provided in quarterly reports under the laws of Nova Scotia, including applicable securities laws and the rules of the Toronto Stock Exchange or any province thereof to security holders of a corporation with securities listed on the Toronto Stock Exchange, whether or not Emera has any of our securities listed on such exchange.

Emera is a foreign private issuer eligible to use the Multi-Jurisdictional Disclosure System available to certain issuers incorporated pursuant to the laws of a Canadian province. As such, Emera is exempt from certain sections of the Exchange Act that U.S. issuers would otherwise be subject to, including the requirement to provide information statements or proxy statements that comply with U.S. securities laws and to file reports under Section 16 of the Exchange Act. For the avoidance of doubt, none of the above reporting requirements shall be construed to require such statements or reports that would not otherwise be required to be filed by foreign private issuers subject to the Multi-Jurisdictional Disclosure System.

Each such report, to the extent permitted by the rules and regulations of the SEC, will be prepared in accordance with Canadian disclosure requirements, provided, however, that Emera shall not be obligated to file such reports with the SEC if the SEC does not permit such filings.

Nothing herein shall be construed to require the registered public accounting firm that prepares or issues the audit report for Emera to attest to, and report on, the assessment made by the management of Emera pursuant to the requirements of Section 404(b) of the Sarbanes-Oxley Act of 2002, unless otherwise required by the Exchange Act.

Neither the Indenture, the Guarantees nor the Notes will afford holders of the Notes protection in the event of a highly leveraged transaction involving the Issuer, Emera or EUSHI, as applicable, or will contain any restrictions on the amount of additional indebtedness that the Issuer, Emera or EUSHI, as applicable, may incur.

The Issuer may “reopen” the Notes and issue additional Notes (the “additional notes”) from time to time without notice or the consent of holders of the Notes. The Notes and any additional Notes subsequently issued under the Indenture, together with any related Notes, will be treated as a single class for all purposes under the Indenture, including, without limitation, waivers, amendments and redemptions; provided that if such additional notes are not fungible with the notes of the applicable series offered hereby for U.S. federal income tax purposes, such additional notes will have a separate CUSIP and/or ISIN number. Except as otherwise specified herein, all references to the notes of any series include any additional notes and Notes of that series. No additional notes may be issued if an Event of Default under the Indenture has occurred and is continuing with respect to the Notes.

The Notes will be issued as one or more global securities in the name of a nominee of DTC and will be available only in book-entry form. The Notes will be issued in denominations of $2,000 and integral multiples of $1,000 in excess thereof.

Amendments of the Indenture and the Notes may be made by the Issuer, the Guarantors and the Trustee with the consent of the holders of a majority in principal amount of the outstanding Notes affected thereby; provided, however, that no such amendment may, without the consent of the holder the Notes affected thereby:

Without the consent of any holder of outstanding Notes, the Issuer, the Guarantors and the Trustee may amend the Indenture and the Notes to:

The holders of a majority in principal amount of the outstanding Notes may, on behalf of the holders of all Notes, waive compliance with any covenant or any past default under the Indenture with respect to the Notes, except a default in the payment of the principal of, premium, if any, or interest on any Note or in respect of a provision which under the Indenture cannot be amended without the consent of the holder of each outstanding Note affected.

It is not necessary for the consent of the holders under the Indenture to approve the particular form of any proposed amendment or waiver. It is sufficient if such consent approves the substance of the proposed amendment or waiver. A consent to any amendment 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 or waiver under the Indenture requiring consent of the holders becomes effective, the Issuer will deliver to the holders and the Trustee a notice briefly describing such amendment or waiver. However, the failure to give such notice, or any defect in the notice, will not impair or affect the validity of the amendment or waiver.

The Issuer will pay principal of, premium, if any, and interest on any Notes issued in certificated form (“Certificated Notes”) at the office or agency the Issuer designates in The City of New York, except that the Issuer may pay interest on any Certificated Notes either at the corporate trust office of the Trustee in The City of New York or, at the Issuer’s option, by check mailed to holders of the Notes at their registered addresses as they appear in the registrar’s books. In addition, if a holder of any Certificated Notes has given wire transfer instructions in accordance with the Indenture, the Issuer will make all payments on those Notes by wire transfer.

The Issuer has initially designated the Trustee, at its corporate trust office in The City of New York, to act as the Issuer’s paying agent and registrar. The Issuer may, however, change the paying agent or registrar without prior notice to the holders of the Notes, and the Issuer or any of the Issuer’s subsidiaries may act as paying agent or registrar.

The Issuer will pay principal of, premium, if any, and interest on, any Note in global form registered in the name of or held by the Depository or its nominee in immediately available funds to the Depository or its nominee, as the case may be, as the registered holder of such global note.

The Issuer will pay principal of, premium, if any, and interest on the Notes in U.S. dollars.

The Issuer may discharge or defease its obligations under the Notes as set forth below.

Under terms specified in the Indenture, the Issuer may discharge certain obligations to holders of the Notes that have not already been delivered to the Trustee for cancellation. The Notes must also:

The Issuer may discharge the Notes by, among other things, irrevocably depositing an amount certified to be sufficient to pay at final maturity, or upon redemption (including with respect to a Tax Event or a Rating Agency Event), the principal, premium, if any, and interest on the Notes. The Issuer may make the deposit in cash, U.S. Government Obligations, or a combination thereof, as defined in the Indenture.

The Issuer may terminate all its obligations under the Notes and the Indenture at any time, except for certain obligations, including those respecting the defeasance trust and obligations to register the transfer or exchange of the Notes, to replace mutilated, destroyed, lost or stolen Notes and to maintain a registrar and paying agent in respect of the Notes. This is referred to as “legal defeasance.” If the Issuer exercises its legal defeasance option with respect to the Notes, the Guarantees in effect at such time will terminate with respect to the Notes.

Under terms specified in the Indenture, the Issuer and the Guarantors may be released with respect to any outstanding Notes from the obligations imposed by the sections of the Indenture that contain the covenants described above under “—Guarantees,” and “—Consolidation, Merger, Conveyance or Transfer.” In that case, the Issuer and the Guarantors would no longer be required to comply with these sections without the creation of an Event of Default under the Notes. This is typically referred to as “covenant defeasance.” If the Issuer exercises the covenant defeasance option with respect to the Notes, the Guarantees of the Notes in effect at the time will terminate. The Issuer may exercise the legal defeasance option notwithstanding the prior exercise of the covenant defeasance option.

Legal defeasance or covenant defeasance with respect to the Notes may be effected by the Issuer only if, among other things:

A holder of Notes may transfer or exchange Notes at the office of the registrar 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 Issuer, the Trustee or the registrar for any registration of transfer or exchange of Notes, but the Issuer may require a holder or beneficial owner to pay a sum sufficient to cover any transfer tax or other similar governmental charge or other fee required by law. The Issuer will not be required to transfer or exchange any Note selected for redemption. Also, the Issuer will not be required to transfer or exchange any Note for a period of 15 days before sending a notice of redemption. The registered holder of a Note will be treated as the owner of it for all purposes.

Under the Indenture, Emera has irrevocably appointed the Issuer as its agent for service of process in any suit, action or proceeding arising out of or relating to the Indenture, the Notes and the Guarantees and for actions brought under federal or state securities laws brought in any Federal or state court located in The City of New York, and has submitted to such non-exclusive jurisdiction.

The Indenture, the Notes and the Guarantees are governed by the internal laws of the State of New York.

Prior to default, the Trustee will perform only those duties specifically set forth in the Indenture. After default, the Trustee will exercise the same degree of care as a prudent individual would exercise in the conduct of his or her own affairs. The Trustee is not required to expend or risk its own funds or otherwise incur personal financial liability in the performance of its duties if it reasonably believes that it may not receive repayment or adequate indemnity.

Because Equiniti Trust Company, LLC is the Trustee under the Indenture, it may be required to resign as Trustee under the Indenture if there is an Event of Default under the Indenture.

The Notes will be represented by one or more global securities that will be deposited with and registered in the name of DTC or its nominee. Thus, we will not issue certificated securities to you for the Notes, except in the limited circumstances described below. Each global security will be issued to DTC, which will keep a computerized record of its participants whose clients have purchased the Notes. Each participant will then keep a record of its clients. Unless it is exchanged in whole or in part for a certificated security, a global security may not be transferred. DTC, its nominees and their successors may, however, transfer a global security as a whole to one another, and these transfers are required to be recorded on our records or a register to be maintained by the Trustee. The laws of some jurisdictions may require that certain purchasers of securities take physical delivery of such securities in definitive form. Such limits and laws may impair the ability to transfer or pledge beneficial interests in the global securities.

Beneficial interests in a global security will be shown on, and transfers of beneficial interests in the global security will be made only through, records maintained by DTC and its participants. DTC has provided us with the following information: DTC 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 United States Federal Reserve System, a “clearing corporation” within the meaning of the New York Uniform Commercial Code and a “clearing agency” registered under the provisions of Section 17A of the Exchange Act. DTC holds securities that its direct participants deposit with DTC. DTC also records the settlements among direct participants of securities transactions, such as transfers and pledges, in deposited securities through computerized records for direct participants’ accounts. This eliminates the need to exchange certificated securities. Direct participants include securities brokers and dealers, banks, trust companies, clearing corporations and certain other organizations, some of whom (and/or their representatives) own DTC.

DTC’s book-entry system is also used by other organizations such as securities brokers and dealers, banks and trust companies that work through a direct participant. The rules that apply to DTC and its participants are on file with the SEC.

When you purchase Notes through the DTC system, the purchases must be made by or through a direct participant, which will receive credit for the Notes on DTC’s records. When you actually purchase the Notes, you will become their beneficial owner. Your ownership interest will be recorded only on the direct or indirect participants’ records. DTC will have no knowledge of your individual ownership of the Notes. DTC’s records will show only the identity of the direct participant and the amount of the Notes held by or through them. You will not receive a written confirmation of your purchase or sale or any periodic account statement directly from DTC. You should instead receive these from your direct or indirect participant. As a result, the direct or indirect participants are responsible for keeping accurate account of the holdings of their customers. The Trustee will wire payments on the Notes to DTC’s nominee. The Trustee and we will treat DTC’s nominee as the owner of each global security for all purposes. Accordingly, the Trustee, any paying agent and we will have no direct responsibility or liability to pay amounts due on a global security to you or any other beneficial owners in that global security. Any redemption notices will be sent by us directly to DTC, which will, in turn, inform the direct participants (or the indirect participants), which will then contact you as a beneficial holder.

It is DTC’s current practice, upon receipt of any payment of distributions or liquidation amounts, to proportionately credit direct participants’ accounts on the payment date based on their holdings. In addition, it is DTC’s current practice to pass through any consenting or voting rights to such participants by using an omnibus proxy. Those participants will, in turn, make payments to and solicit votes from you, the ultimate owner of Notes, based on their customary practices. Payments to you will be the responsibility of the participants and not of DTC, the Trustee or our company.

Notes represented by one or more global securities will be exchangeable for certificated securities with the same terms in authorized denominations only if:

If the global security is exchanged for certificated securities, the Trustee will keep the registration books for the Notes at its corporate trust office and follow customary practices and procedures regarding those certificated securities.

Links have been established among DTC, Euroclear Bank SA/NV, as operator of the Euroclear System (“Euroclear”) and Clearstream Banking S.A. (“Clearstream”), which are two European book-entry depositaries similar to DTC, to facilitate the initial issuance of the Notes sold outside of the United States of America and cross-market transfers of the Notes associated with secondary market trading.

Although DTC, Clearstream and Euroclear have agreed to the procedures provided below in order to facilitate transfers, they are under no obligation to perform these procedures, and these procedures may be modified or discontinued at any time.

Clearstream and Euroclear will record the ownership interests of their participants in much the same way as DTC, and DTC will record the total ownership of each of the U.S. agents of Clearstream and Euroclear, as participants in DTC.

When Notes are to be transferred from the account of a DTC participant to the account of a Clearstream participant or a Euroclear participant, the purchaser must send instructions to Clearstream or Euroclear through a participant at least one day prior to settlement. Clearstream or Euroclear, as the case may be, will instruct its U.S. agent to receive Notes against payment. After settlement, Clearstream or Euroclear will credit its participant’s account. Credit for the Notes will appear on the next day (European time).

Because settlement is taking place during New York business hours, DTC participants will be able to employ their usual procedures for sending Notes to the relevant U.S. agent acting for the benefit of Clearstream or Euroclear participants. The sale proceeds will be available to the DTC seller on the settlement date. As a result, to the DTC participant, a cross-market transaction will settle no differently than a trade between two DTC participants.

When a Clearstream or Euroclear participant wishes to transfer Notes to a DTC participant, the seller will be required to send instructions to Clearstream or Euroclear through a participant at least one Business Day prior to settlement. In these cases, Clearstream or Euroclear will instruct its U.S. agent to transfer these Notes against payment for them. The payment will then be reflected in the account of the Clearstream or Euroclear participant the following day, with the proceeds back-valued to the value date, which would be the preceding day, when settlement occurs in New York. If settlement is not completed on the intended value date, that is, the trade fails, proceeds credited to the Clearstream or Euroclear participant’s account will instead be valued as of the actual settlement date.

Each of the summaries under this section “Material Income Tax Considerations” is of a general nature only and is not intended to be, and should not be construed to be, legal or tax advice to any particular holder, and no representation is made with respect to the United States federal tax consequences or Canadian tax consequences to any particular holder. Accordingly, prospective purchasers are urged to consult their own tax advisors with respect to the United States federal tax consequences or Canadian tax consequences relevant to them, having regard to their particular circumstances.

The following are the material U.S. federal income tax consequences of ownership and disposition of the Notes. This discussion applies only to Notes that meet both of the following conditions:

This discussion does not describe all aspects of U.S. federal income taxes and does not deal with all of the tax consequences that may be relevant to holders in light of their particular circumstances or to holders subject to special rules such as:

If an entity or arrangement treated as a partnership for U.S. federal income tax purposes holds Notes, the U.S. federal income tax treatment of a partner will generally depend upon the status of the partner and the activities of the partnership. Partners of partnerships holding Notes should consult their tax advisors as to the particular U.S. federal income tax consequences to them of holding and disposing of the Notes.

This summary is based on the Code, administrative pronouncements, judicial decisions and final, temporary and proposed U.S. Treasury Regulations in effect as of the date hereof, changes to any of which subsequent to the date of this prospectus supplement may affect the tax consequences described herein, possibly with retroactive effect.

This summary addresses only U.S. federal income tax consequences. Persons considering the purchase of Notes should consult their tax advisors with regard to the application of the U.S. federal income or other federal tax laws (including estate and gift tax laws and the Medicare tax on investment income) to their particular situations as well as any tax consequences arising under the laws of any state, local or foreign taxing jurisdiction.

The determination of whether a security should be classified as indebtedness or equity for U.S. federal income tax purposes requires a judgment based on all relevant facts and circumstances. There is no statutory, judicial or administrative authority that directly addresses the U.S. federal income tax treatment of securities similar to the Notes. Under current law and based on the facts contained in this prospectus supplement, the terms of the Indenture and the Notes, and certain assumptions and representations, the Notes should be classified for U.S. federal income tax purposes as indebtedness and interest thereon should be treated as U.S. source (although there is no controlling authority directly on point with respect to the treatment of the Notes and interest thereon). This treatment is not binding on the Internal Revenue Service (the “IRS”) or the courts. Moreover, no rulings have been or will be sought from the IRS with respect to the transactions described in this prospectus supplement. Accordingly, the Issuer cannot assure holders that the IRS will not challenge the treatment described herein or that a court would not sustain such a challenge. If the IRS were to successfully challenge this treatment, interest payments on the Notes could be treated for U.S. federal income tax purposes as dividends to the extent of the applicable current or accumulated earnings and profits. In the case of Non-U.S. Holders (as defined below), interest payments treated as dividends could be subject to withholding of U.S. income tax, except to the extent a reduced rate is provided by an applicable income tax treaty. In addition, such a determination could constitute a Tax Event that would entitle us to redeem the Notes as described under “Description of the Notes—Redemption—Redemption Following a Tax Event.” The Issuer agrees, and by acquiring an interest in a Note, each beneficial owner of a Note will agree, to treat the Notes as indebtedness and the interest thereon as U.S. source, for U.S. federal income tax purposes. Holders should consult their tax advisors regarding the tax consequences that will arise if the Notes are not so treated. The remainder of this discussion assumes such treatment is respected.

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

Subject to the discussion immediately below, stated interest paid on a Note will be taxable to a U.S. Holder as ordinary interest income at the time it accrues or is received, in accordance with the U.S. Holder’s method of accounting for U.S. federal income tax purposes.

The Notes should be treated as “variable rate debt instruments” for U.S. federal income tax purposes. If the Notes were not treated as variable rate debt instruments, then the Notes would generally be treated as “contingent payment debt instruments,” in which case U.S. Holders could be required to accrue interest income on the Notes in excess of stated interest and would be required to treat as ordinary income rather than as capital gain any income realized on a taxable disposition of the Notes. Applicable Treasury Regulations set forth rules to determine whether a variable rate debt instrument is treated as issued with original issue discount for U.S. federal income tax purposes (“OID”). Based on the application of these Treasury Regulations and the expected pricing terms of the Notes, the Issuer does not expect the pricing of the Notes to result in the Notes as being treated as issued with OID. The Issuer has the option under certain circumstances to defer payments of stated interest on the Notes. Under the Treasury Regulations relating to OID, a debt instrument is deemed to be issued with OID if there is more than a “remote” contingency that periodic stated interest payments due on the instrument will not be timely paid. The Issuer believes the likelihood of exercising the option to defer payment of stated interest on the Notes is remote within the meaning of the Treasury Regulations in part because the exercise of the option to defer payments of stated interest on the Notes would generally prevent the Issuer from:

Similarly, if certain circumstances occur (see “Description of the Notes—Redemption—Redemption Following a Rating Agency Event”), the Issuer will be obligated to pay amounts in excess of stated principal of the Notes. Such excess payments will not affect the amount of interest income that a U.S. Holder recognizes if there is only a remote likelihood that such payments will be made. The Issuer believes the likelihood that it will make any such payments is remote.

Based on these positions, a U.S. Holder generally should be required to recognize any stated interest as ordinary income at the time it is received or accrued on the Notes in accordance with such holder’s regular method of accounting for U.S. federal income tax purposes, as described above. The Issuer’s determination that these contingencies are remote is binding on a U.S. Holder unless such holder discloses its contrary position in the manner required by applicable Treasury Regulations. The Issuer’s determination is not, however, binding on the IRS. There can be no assurance that the IRS or a court will agree with these positions. The meaning of the term “remote” in the Treasury Regulations has not yet been addressed in any rulings or other guidance by the IRS or any court. If the possibility of interest deferral were determined not to be remote, the Notes would be treated as issued with OID and all stated interest would be treated as OID as long as the Notes are outstanding. In that case, U.S. Holders would be required to accrue interest income on the Notes using a constant yield method whether or not they receive any cash payment attributable to that interest, regardless of their regular method of accounting for U.S. federal income tax purposes.

Moreover, if the possibility of excess payments following a Rating Agency Event were determined not to be remote, the Notes could be treated as “contingent payment debt instruments,” in which case U.S. Holders could be required to accrue interest income on the Notes in excess of stated interest and would be required to treat as ordinary income rather than as capital gain any income realized on a taxable disposition of the Notes, as described below.

The remainder of this discussion assumes the Notes will not be treated as issued with OID or as contingent payment debt instruments.

Under the Treasury Regulations, if the Issuer exercises the option to defer the payment of interest on the Notes, the Notes will be treated as if they had been redeemed and reissued solely for OID purposes. In that event, all remaining interest payments on the Notes (including interest on deferred interest) would be treated as OID, which U.S. Holders would be required to accrue and include in taxable income, without regard to such U.S. Holders’ regular method of accounting for U.S. federal income tax purposes. The amount of OID includible in such U.S. Holders’ taxable income would be determined on the basis of a constant yield method over the remaining term of the Notes, and the actual receipt of future payments of stated interest on the Notes would no longer be separately reported as taxable income. The total amount of OID that would accrue during the deferral period would be approximately equal to the amount of the cash payment due immediately following the end of that period. Any OID included in income would increase U.S. Holders’ adjusted tax basis in their Notes, and their actual receipt of cash interest payments would reduce that adjusted tax basis.

Upon the sale, exchange or retirement of a Note that is a taxable disposition, a U.S. Holder will recognize taxable gain or loss equal to the difference between the amount realized on such sale, exchange or retirement and the U.S. Holder’s adjusted tax basis in the Note, which will generally equal the cost of the Note. For these purposes, the amount realized does not include any amount attributable to accrued interest. Amounts attributable to accrued interest are treated as interest as described under “Payments of Interest” above. If the Notes are treated as having been issued or reissued with OID, such adjusted tax basis will also be increased by the amount of any OID previously included in a U.S. Holder’s gross income with respect to the Notes and decreased by any payments received on the Notes since and including the date that the Notes were deemed to be issued with OID.

Gain or loss realized on the sale, exchange or retirement of a Note will generally be capital gain or loss and will be long-term capital gain or loss if at the time of sale, exchange or retirement the Note has been held for more than one year. The deductibility of capital losses is subject to limitations.

Information returns generally will be filed with the IRS in connection with payments on the Notes (including OID) and the proceeds from a sale or other disposition of the Notes. A U.S. Holder will be subject to backup withholding on these payments if the U.S. Holder fails to provide its correct taxpayer identification number to the applicable withholding agent and comply with certain certification procedures or otherwise establish an exemption from backup withholding. Backup withholding is not an additional tax. The amount of any backup withholding from a payment to a U.S. Holder will be allowed as a credit against the U.S. Holder’s U.S. federal income tax liability and may entitle the U.S. Holder to a refund, provided that the required information is timely furnished to the IRS.

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

The term “Non-U.S. Holder” does not include a beneficial owner who is an individual present in the United States for 183 days or more in the taxable year of disposition or who is (or may become while holding Notes) a former citizen or resident of the United States. Such a beneficial owner is urged to consult his or her own tax advisor regarding the U.S. federal income tax consequences of the sale, exchange or other disposition of a Note.

Subject to the discussions below concerning backup withholding and FATCA (as defined below), payments of principal, interest (including any OID) and premium on the Notes to a Non-U.S. Holder generally will not be subject to U.S. federal income tax or withholding, provided that, in the case of interest:

Subject to the discussion below concerning income of a Non-U.S. Holder that is effectively connected with the conduct of a trade or business in the United States, if a Non-U.S. Holder cannot satisfy the requirements described above, payments of interest on the Notes to such Non-U.S. Holder will generally be subject to 30% U.S. federal withholding, unless the Non-U.S. Holder provides the applicable withholding agent with a properly executed IRS Form W-8 appropriate to the Non-U.S. Holder’s circumstances claiming an exemption from or reduction in withholding under an applicable income tax treaty and complies with any other applicable procedures. See the discussion below under “FATCA” regarding withholding on interest under the FATCA rules.

A Non-U.S. Holder of a Note will not be subject to U.S. federal income tax on gain realized on the sale, exchange or retirement of such Note, unless the gain is effectively connected with the conduct by the Non-U.S. Holder of a trade or business in the United States, subject to an applicable income tax treaty providing otherwise, although any amounts attributable to accrued interest will generally be treated as described above under “Payments on the Notes.” See the discussion below under “FATCA” regarding withholding under the FATCA rules on gross proceeds of the sale, exchange or retirement of the Notes.

If a Non-U.S. Holder of a Note is engaged in a trade or business in the United States, and if income or gain on the Note is effectively connected with the conduct of this trade or business (and if required by an applicable income tax treaty, the income or gain is attributable to a permanent establishment or fixed base maintained by the Non-U.S. Holder in the United States), the Non-U.S. Holder, although exempt from the withholding tax on interest discussed above, will generally be taxed in the same manner as a U.S. Holder (see “Tax Consequences to U.S. Holders” above), except that the Non-U.S. Holder will be required to provide to the applicable withholding agent a properly executed IRS Form W-8ECI in order to claim an exemption from withholding tax on interest. These Non-U.S. Holders should consult their tax advisors with respect to other U.S. tax consequences of the ownership and disposition of Notes, including, in the case of a corporation, the possible imposition of a branch profits tax at a rate of 30% (or a lower rate under an applicable income tax treaty).

Information returns generally will be filed with the IRS in connection with interest payments on the Notes.

Copies of the information returns reporting such interest payments and any withholding may also be made available to the tax authorities in the country in which the Non-U.S. Holder resides under the provisions of an applicable income tax treaty. Unless the Non-U.S. Holder complies with certification procedures to establish that it is not a United States person, information returns may be filed with the IRS in connection with the proceeds from a sale or other disposition of the Notes, and the Non-U.S. Holder may be subject to backup withholding on payments on the Notes or on the proceeds from a sale or other disposition of the Notes. Compliance with the certification procedures required to claim the exemption from withholding tax on interest described above will satisfy the certification requirements necessary to avoid backup withholding as well. Backup withholding is not an additional tax. The amount of any backup withholding from a payment to a Non-U.S. Holder will be allowed as a credit against the Non-U.S. Holder’s U.S. federal income tax liability and may entitle the Non-U.S. Holder to a refund, provided that the required information is furnished to the IRS.

Provisions in the Code and the U.S. Treasury Regulations promulgated thereunder, commonly referred to as “FATCA,” generally impose a withholding tax of 30% on payments to certain non-U.S. entities (including financial intermediaries) with respect to certain financial instruments, unless various U.S. information reporting and due diligence requirements have been satisfied. An intergovernmental agreement between the United States and the non-U.S. entity’s jurisdiction may modify these requirements. Withholding under these rules (if applicable) applies to payments of interest on the Notes (including any OID) and to payments of gross proceeds of the sale, exchange or retirement of the Notes. However, under proposed U.S. Treasury Regulations (the preamble to which specifies that taxpayers are permitted to rely on them pending finalization), no withholding will apply on payments of gross proceeds. Non-U.S. Holders, and U.S. Holders holding Notes through a non-U.S. intermediary, should consult their tax advisors regarding the potential application of FATCA to the Notes.

The following summary describes the principal Canadian federal income tax considerations under the Tax Act generally applicable to a purchaser who acquires notes, including entitlement to all payments thereunder, as a beneficial owner pursuant to this offering and who, at all relevant times, for purposes of the application of the Tax Act, (1) is not, and is not deemed to be, resident in Canada; (2) deals at arm’s length with the Issuer and the Guarantors, and with any transferee resident (or deemed to be resident) in Canada to whom the purchaser disposes of the notes; (3) does not use or hold the notes in a business carried on in Canada; (4) is not a “specified non-resident shareholder” of Emera for purposes of the Tax Act or a non-resident person not dealing at arm’s length with a “specified

shareholder” (within the meaning of Subsection 18(5) of the Tax Act) of Emera; and (5) is not an entity in respect of which Emera is a “specified entity” (as defined in the Tax Act) and is not a “specified entity” in respect of any transferee resident (or deemed to be resident) in Canada to whom the purchaser disposes of the notes (a “Non-Canadian Holder”). Special rules, which are not discussed in this summary, may apply to a Non-Canadian Holder that is an insurer that carries on an insurance business in Canada and elsewhere.

This summary is based on the current provisions of the Tax Act and on counsel’s understanding of the current administrative policies and assessing practices of the Canada Revenue Agency (the “CRA”) published in writing prior to the date hereof. This summary takes into account all specific proposals to amend the Tax Act publicly announced by or on behalf of the Minister of Finance (Canada) prior to the date hereof (the “Proposed Amendments”) and assumes that all Proposed Amendments will be enacted in the form proposed. However, no assurances can be given that the Proposed Amendments will be enacted as proposed, or at all. This summary does not otherwise take into account or anticipate any changes in law or administrative policy or assessing practice of the CRA whether by legislative, administrative or judicial action nor does it take into account tax legislation or considerations of any province, territory or foreign jurisdiction, which may differ from those discussed herein.

This summary is of a general nature only and is not, and is not intended to be, legal or tax advice to any particular holder. This summary is not exhaustive of all Canadian federal income tax considerations. Accordingly, prospective purchasers of notes should consult their own tax advisors having regard to their own particular circumstances.

No Canadian withholding tax will apply to interest, principal and premium, if any, paid or credited to a Non-Canadian Holder by the Issuer on a note or to the proceeds received by a Non-Canadian Holder on the disposition of a note including a redemption, payment on maturity or repurchase.

No other tax on income or gains will be payable by a Non-Canadian Holder on interest, principal or premium, if any, paid or credited to a Non-Canadian Holder by the Issuer on a note or on the proceeds received by a Non-Canadian Holder on the disposition of a note including a redemption, payment on maturity or repurchase.

J.P. Morgan Securities LLC, Morgan Stanley & Co LLC, MUFG Securities Americas Inc., RBC Capital Markets, LLC, Scotia Capital (USA) Inc. and Wells Fargo Securities, LLC are acting as representatives (the “Representatives”) of the underwriters named below.

Subject to the terms and conditions stated in the underwriting agreement dated the date of this prospectus supplement, each underwriter named below has severally and not jointly agreed to purchase, and we have agreed to sell to that underwriter, the principal amount of Notes set forth opposite such underwriter’s name.

The underwriters are offering the Notes subject to prior sale, when, as and if issued and accepted by them, subject to approval of legal matters by counsel and to other conditions. The underwriters are obligated to purchase all the Notes if they purchase any of the Notes. The underwriters reserve the right to cancel, reject or modify an order of Notes in whole or in part.

The underwriters propose to offer the Notes directly to the public at the public offering price set forth on the cover page of this prospectus supplement and may offer the Notes to dealers at the public offering price less a concession not to exceed % of the principal amount of the Notes. The underwriters may allow, and dealers may reallow, a concession not to exceed % of the principal amount of the Notes. After the initial offering of the Notes to the public, the underwriters may change the public offering price, concessions and other selling terms.

In connection with this offering, the underwriters may purchase and sell Notes in the open market. These transactions may include over-allotment, syndicate covering transactions and stabilizing transactions. Over-allotment involves syndicate sales of the Notes in excess of the principal amount of the Notes to be purchased by the underwriters in this offering, which creates a syndicate short position. Syndicate covering transactions involve purchases of the Notes in the open market after the distribution has been completed in order to cover syndicate short positions. Stabilizing transactions consist of certain bids or purchases of Notes made for the purpose of preventing or retarding a decline in the market price of the Notes while this offering is in progress.

Any of these activities may have the effect of preventing or retarding a decline in the market price of the Notes. They may also cause the price of the Notes to be higher than the price that otherwise would exist in the open market in the absence of these transactions. The underwriters may conduct these transactions in the over-the-counter market or otherwise. If the underwriters commence any of these transactions, they may discontinue them at any time. There will be no obligation on the underwriters to engage in these activities.

The Notes are a new issue of securities and no established trading market for the Notes exists. The Notes will not be listed on any automated dealer quotation system, and we do not intend to apply for listing of the Notes on any securities exchange. We have been advised that the underwriters intend to make a market in the Notes. However, they are not obligated to do so, and they may discontinue any market-making activities with respect to the Notes at any time without notice. No assurance can be given as to the liquidity of the trading market for the Notes or that an active public market for the Notes will develop. If an active public trading market for the Notes does not develop, the market price and liquidity of the Notes may be adversely affected.

The following table shows the underwriting discount that we will pay the underwriters in connection with this offering (expressed as a percentage of the principal amount of the Notes).

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

The underwriters or their respective affiliates perform and have performed commercial banking, investment banking and advisory services for us from time to time for which they receive and have received customary fees and expenses. The underwriters and their affiliates may, from time to time, engage in transactions with and perform services for us in the ordinary course of their business. In addition, in the ordinary course of their business activities, the underwriters and their 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. These investments and securities activities may involve securities and/or instruments of ours or our affiliates. The underwriters and their affiliates may also make investment recommendations and/or publish or express independent research views in respect of these securities or financial instruments and may hold, or recommend to clients that they acquire, long and/or short positions in these securities and instruments.

If any of the underwriters or their affiliates has a lending relationship with us or our affiliates, certain of those underwriters or their affiliates routinely hedge, certain other of those underwriters or their affiliates have hedged and are likely in the future to hedge, and certain other of those underwriters of their affiliates may hedge, their credit exposure to us consistent with their customary risk management policies. Typically, these underwriters and their affiliates would hedge that exposure by entering into transactions which consist of either the purchase of credit default swaps or the creation of short positions in our affiliates’ securities, including potentially the Notes offered hereby. Any of these credit default swaps or short positions could adversely affect future trading prices of the Notes offered hereby.

Affiliates of RBC Capital Markets, LLC and Scotia Capital (USA) Inc. are lenders under the Revolving Facility and an affiliate of RBC Capital Markets, LLC is a lender under the Non-Revolving Facility (collectively, the “Facilities”). The lenders under the Facilities were not involved in their capacity as such in the decision to issue the Notes or in determining the price of the Notes or the terms of this offering. The financial position of Emera has not materially changed since indebtedness was incurred under the Facilities, other than as has been publicly disclosed and/or as described in this prospectus. Emera is currently in compliance with all covenants under the Facilities, and no breach thereof has been waived by any of the lenders since the execution of such facilities. As of September 26, 2025, Emera had approximately C$1,060 million drawn on the Revolving Facility and C$200 million drawn on the Non-Revolving Facility.

The decision to offer the Notes was made solely by the Issuer and Emera and the terms upon which the Notes are being offered were determined by negotiation between the Issuer and RBC Capital Markets, LLC and Scotia Capital (USA) Inc. RBC Capital Markets, LLC and Scotia Capital (USA) Inc. will not receive any proceeds of the offering except as described above.

We have agreed to indemnify the underwriters against certain liabilities, including liabilities under the U.S. Securities Act, or to contribute to payments the underwriters may be required to make because of any of those liabilities.

We expect that delivery of the Notes will be made against payment therefor on or about the date specified on the cover page of this prospectus supplement, which will be the business day following the date of pricing of the Notes (this settlement cycle being herein referred to as “T+ ”). Under Rule 15c6-1 of 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 more than one business day prior to the scheduled settlement date will be required, by virtue of the fact that the Notes initially will settle in T+ , to specify an alternate settlement cycle at the time of any such trade to prevent a failed settlement. Purchasers of the Notes who wish to make such trades should consult their own advisor.

The Notes may be sold only to purchasers purchasing, or deemed to be purchasing, as principal that are accredited investors, as defined in National Instrument 45-106 Prospectus Exemptions or subsection 73.3(1) of the Securities Act (Ontario), and are permitted clients, as defined in National Instrument 31-103 Registration Requirements, Exemptions and Ongoing Registrant Obligations. Any resale of the Notes must be made in accordance with an exemption from, or in a transaction not subject to, the prospectus requirements of applicable securities laws.

Securities legislation in certain provinces or territories of Canada may provide a purchaser with remedies for rescission or damages if this prospectus supplement or the accompanying prospectus (including any amendment hereto or thereto) contains a misrepresentation, provided that the remedies for rescission or damages are exercised by the purchaser within the time limit prescribed by the securities legislation of the purchaser’s province or territory. The purchaser should refer to any applicable provisions of the securities legislation of the purchaser’s province or territory for particulars of these rights or consult with a legal advisor.

The Notes are not intended to be offered, sold or otherwise made available to and should not be offered, sold or otherwise made available to any retail investor in the European Economic Area (“EEA”). For these purposes, a retail investor means a person who is one (or more) of: (i) a retail client as defined in point (11) of Article 4(1) of Directive 2014/65/EU (as amended, “MiFID II”); or (ii) a customer within the meaning of Directive (EU) 2016/97 (as amended, the “Insurance Distribution Directive”), where that customer would not qualify as a professional client as defined in point (10) of Article 4(1) of MiFID II; or (iii) not a qualified investor as defined in Regulation (EU) 2017/1129 (as amended, the “Prospectus Regulation”). Consequently, no key information document required by Regulation (EU) No 1286/2014 (as amended, the “PRIIPs Regulation”) for offering or selling the Notes or otherwise making them available to retail investors in the EEA has been prepared and therefore offering or selling the Notes or otherwise making them available to any retail investor in the EEA may be unlawful under the PRIIPs Regulation. This prospectus supplement and the accompanying prospectus have been prepared on the basis that any offer of Notes in any member state of the EEA will be made pursuant to an exemption under the Prospectus Regulation from the requirement to publish a prospectus for offers of Notes. This prospectus supplement and the accompanying prospectus is not a prospectus for the purposes of the Prospectus Regulation.

The Notes are not intended to be offered, sold or otherwise made available to and should not be offered, sold or otherwise made available to any retail investor in the United Kingdom (“UK”). For these purposes, a retail investor means a person who is one (or more) of: (i) a retail client, as defined in point (8) of Article 2 of Regulation (EU) No 2017/565 as it forms part of domestic law by virtue of the European Union (Withdrawal) Act 2018 (as amended, the “EUWA”); or (ii) a customer within the meaning of the provisions of the Financial Services and Markets Act 2000 (as amended, the “FSMA”) and any rules or regulations made under the FSMA to implement the Insurance Distribution Directive, where that customer would not qualify as a professional client, as defined in point (8) of Article 2(1) of Regulation (EU) No 600/2014 as it forms part of domestic law by virtue of the EUWA; or (iii) not a qualified investor as defined in Article 2 of Regulation (EU) 2017/1129 as it forms part of domestic law by virtue of the EUWA (the “UK Prospectus Regulation”). Consequently, no key information document required by Regulation (EU) 1286/2014 as it forms part of domestic law by virtue of the EUWA (the “UK PRIIPs Regulation”) for offering or selling the Notes or otherwise making them available to retail investors in the UK has been prepared and therefore offering or selling the Notes or otherwise making them available to any retail investor in the UK may be unlawful under the UK PRIIPs Regulation. This prospectus supplement and the accompanying prospectus have been prepared on the basis that any offer of Notes in the UK will be made pursuant to an exemption under the UK Prospectus Regulation from the requirement to publish a prospectus for offers of Notes. This prospectus supplement and the accompanying prospectus is not a prospectus for the purposes of the UK Prospectus Regulation or the FSMA.

In the UK, this prospectus supplement is for distribution only to persons who (i) have professional experience in matters relating to investments and who qualify as investment professionals within the meaning of Article 19(5) of the Financial Services and Markets Act 2000 (Financial Promotion) Order 2005 (as amended, the “Financial Promotion Order”) or (ii) are persons falling within Article 49(2)(a) to (d) (“high net worth companies, unincorporated associations etc.”) of the Financial Promotion Order (all such persons together being referred to as “relevant persons”).

No advertisement, invitation or document relating to the Notes has been, may be or will be issued, or has been, may be, or will be in the possession of any person for the purpose of issue (in each case whether in Hong Kong or elsewhere), which is directed at, or the contents of which are likely to be accessed or read by, the public of Hong Kong (except if permitted to do so under the securities laws of Hong Kong) other than with respect to the Notes which are or are intended to be disposed of only to persons outside Hong Kong or only to “professional investors” as defined in the Securities and Futures Ordinance (Cap. 571, Laws of Hong Kong) and any rules made thereunder.

This offering of the Notes has not been and will not be registered pursuant to Article 4, Paragraph 1 of the Financial Instruments and Exchange Act of Japan (Act No. 25 of April 13, 1948, as amended; the “FIEA”).

The Debt Securities will be senior and/or subordinated unsecured obligations of EUSHI Finance and will be guaranteed on a senior and/or subordinated, unsecured basis, jointly and severally (the “Guarantees”), by Emera Incorporated, a Nova Scotia company (“Emera”) and its subsidiary, Emera US Holdings Inc., a Delaware corporation (“EUSHI”, and together with Emera, the “Guarantors”). EUSHI is a direct and indirect wholly-owned subsidiary of Emera and the Issuer is a direct, wholly-owned subsidiary of EUSHI. All references to “Debt Securities” in this prospectus shall include the related Guarantees by the Guarantors.

EUSHI Finance will provide the specific terms of the Debt Securities in respect of which this prospectus is being delivered in applicable prospectus supplements and may include, where applicable, the specific designation, aggregate principal amount, currency, maturity, interest provisions, authorized denominations, offering price, any terms for redemption at our option or at the option of the holder and any other specific terms. You should read this prospectus and any applicable prospectus supplements carefully before you invest. Debt Securities may consist of debentures, notes or other types of debt and may be issuable in series. This prospectus may not be used to offer Debt Securities unless accompanied by a prospectus supplement. Our intended use for any net proceeds that we expect to receive from the issue of Debt Securities will be set forth in a prospectus supplement.

Investing in the Debt Securities is subject to certain risks. See the “Risk Factors” section on page 10 of this prospectus, in any accompanying prospectus supplement or in the documents incorporated by reference into this prospectus and the accompanying prospectus supplement before making a decision to invest in our securities.

We are permitted, under a multijurisdictional disclosure system adopted by the United States and Canada, to prepare this prospectus in accordance with Canadian disclosure requirements. Prospective investors should be aware that such requirements are different from those of the United States. The financial statements of Emera and its consolidated subsidiaries included or incorporated by reference in this prospectus have been prepared in accordance with U.S. Generally Accepted Account Principles

(“GAAP”). Our financial statements are audited in accordance with the standards of the Public Company Accounting Oversight Board (PCAOB). Ernst & Young LLP, Emera’s independent registered public accounting firm, has advised that they comply with the auditor independence rules of the U.S. Securities and Exchange Commission (the “SEC”) and the requirements of the PCAOB.

Owning the Debt Securities may have tax consequences in both the United States and Canada. You should consult your own tax advisor with respect to your own particular circumstances and read the tax discussion in this prospectus and any applicable prospectus supplement.

The ability of investors to enforce civil liabilities under U.S. federal securities laws may be affected adversely by the fact that Emera is incorporated under the laws of Nova Scotia, some of the officers and directors of Emera, EUSHI and EUSHI Finance and some of the experts named in this prospectus and the documents incorporated by reference herein are non-U.S. residents, and some of our assets and some of the assets of those officers, directors and experts are located outside of the United States.

Unless otherwise specified in an applicable prospectus supplement, the Debt Securities will not be listed on any securities or stock exchange or on any automated dealer quotation system. There may be no market through which the Debt Securities may be sold and purchasers may not be able to resell the Debt Securities purchased under this prospectus. This may affect the pricing of the Debt Securities in the secondary market, the transparency and availability of trading prices and the liquidity of the Debt Securities. See the “Risk Factors” section of this prospectus.

Prospective investors should be aware that, during any period in which offers and sales of Debt Securities are being made, the registrants or their respective affiliates, directly or indirectly, may bid for or make purchases of the Debt Securities or certain related debt securities, as permitted by applicable laws or regulations of Canada, or its provinces or territories.

THESE DEBT SECURITIES HAVE NOT BEEN APPROVED OR DISAPPROVED BY THE U.S. SECURITIES AND EXCHANGE COMMISSION OR ANY STATE SECURITIES REGULATOR NOR HAS THE U.S. SECURITIES AND EXCHANGE COMMISSION OR ANY STATE SECURITIES REGULATOR PASSED UPON THE ACCURACY OR ADEQUACY OF THIS PROSPECTUS.

This prospectus is part of the joint registration statement on Forms F-10 and F-3 relating to the Debt Securities that we filed with the U.S. Securities and Exchange Commission (the “SEC”). Under this “shelf” registration process, we may, from time to time, sell any combination of Debt Securities in one or more offerings up to an aggregate principal amount of US$3,000,000,000. This prospectus provides you with a general description of the Debt Securities that we may offer. Each time we sell Debt Securities under the registration statement, we will provide a prospectus supplement that will contain specific information about the terms, including the issuer, of that offering of Debt Securities. The prospectus supplement may also add, update or change information contained in this prospectus. Before you invest, you should read both this prospectus and any applicable prospectus supplement together with additional information described under the heading “Where You Can Find More Information.” This prospectus does not contain all of the information contained in the registration statement, certain parts of which are omitted in accordance with the rules and regulations of the SEC. You should refer to the registration statement and the exhibits to the registration statement for further information with respect to us and the Debt Securities.

We have not authorized anyone to provide you with any information other than that contained or incorporated by reference in this prospectus or in any free writing prospectus prepared by or on behalf of us or to which we have referred you. We take no responsibility for, and can provide no assurance as to the reliability of, any other information that others may give you.

Emera is a reporting issuer in Canada, and as such Emera is subject to continuous disclosure and other obligations applicable to Canadian reporting issuers under applicable Canadian provincial securities laws. Emera files annual and quarterly reports, management’s discussion and analysis, management information circulars, annual information forms and other information with the various securities commissions or other securities regulatory authorities in the provinces of Canada (the “CSA”). The filings that Emera makes with the CSA may be retrieved, accessed and printed, free of charge, through SEDAR+, the secure web-based system used by all market participants to file, disclose and search for information in Canada’s capital markets maintained on behalf of the CSA. The URL of that website is http://www.sedarplus.ca. In addition, the SEC maintains an Internet site at http://www.sec.gov (“EDGAR”) that contains reports, proxy and information statements and other information Emera has filed or furnished electronically with the SEC. Emera also makes this and other information available on its corporate website at http://www.emera.com. The information found on its corporate website and the information that it files on SEDAR+ or files or furnishes on EDGAR does not, except as specifically set forth below, form part of this prospectus and is not incorporated by reference herein.

Emera is a company incorporated under and governed by the Companies Act (Nova Scotia). Some of the directors and officers of Emera, EUSHI and EUSHI Finance, as well as certain of the experts named in this prospectus and the documents incorporated by reference into this prospectus, are non-U.S. residents and all or a substantial portion of their assets and a substantial portion of Emera’s assets are located outside of the United States. It may be difficult for holders of Debt Securities to effect service within the United States upon the directors and officers of Emera, EUSHI and EUSHI Finance and the experts named in this prospectus and any documents incorporated by reference into this prospectus who are not residents of the United States or to enforce against them in the United States judgments of courts of the United States predicated upon civil liability under United States federal securities laws. While we believe that a monetary judgment of a United States court predicated solely upon civil liability under United States federal securities laws would likely be enforceable in Canada if the United States court in which the judgment was obtained had a basis for jurisdiction in the matter that was recognized by a Canadian court for such purposes, we cannot assure you that this will be the case. It is less certain that an action could be brought in Canada in the first instance on the basis of liability predicated solely upon such laws.

Each of EUSHI and EUSHI Finance is a corporation formed under the laws of the State of Delaware.

EUSHI Finance, EUSHI, and certain of the directors and officers of EUSHI Finance and the Guarantors, reside outside of Canada. These individuals and entities have appointed Emera, as their agent for service of process in Canada:

Purchasers are advised that it may not be possible for investors to enforce judgments obtained in Canada against any person that is incorporated, continued or otherwise organized under the laws of a foreign jurisdiction or resides outside of Canada, even if the person has appointed an agent for service of process in Canada.

Any statement contained in a document incorporated or deemed to be incorporated by reference in this prospectus shall be deemed to be modified or superseded for purposes of this prospectus to the extent that a statement contained herein, or in any other subsequently filed or furnished document which also is incorporated or is deemed to be incorporated by reference herein, modifies or supersedes such statement. The modifying or superseding statement need not state that it has modified or superseded a prior statement or include any other information set forth in the document that it modifies or supersedes.

Emera was incorporated in the Province of Nova Scotia in 1998 and is the direct or indirect owner of all of the shares in EUSHI. Emera’s principal executive office is located at 5151 Terminal Road, P.O. Box 910, Halifax, NS B3J 1A1, Canada, and Emera’s telephone number is (902) 450-0507.

EUSHI Finance is a Delaware corporation that was formed on May 20, 2016. EUSHI Finance is owned indirectly by Emera through EUSHI. EUSHI Finance was formed for the purpose of Emera’s intercompany financings and does not have any operations or assets other than interests in other financing-related entities, and it does not have any operating revenues.

Investing in the Debt Securities is subject to certain risks. Before purchasing Debt Securities, you should consider carefully the risk factors set forth under the heading “Risk Factors” in Emera’s annual information form, which is contained in Emera’s annual report on Form 40-F for the year ended December 31, 2024 (and our annual information forms for subsequent years), as well as the other information contained in and incorporated by reference in this prospectus (including subsequently filed documents incorporated by reference) and, if applicable, those described and incorporated by reference in the applicable prospectus supplement. If any of the events or developments discussed in these risks actually occur, our business, financial condition or results of operations or the value of the Debt Securities could be adversely affected.

As of June 30, 2025, Emera had $2.95 billion USD (as of December 31, 2024 – $2.95 billion USD) senior unsecured notes issued by Emera US Finance LP and junior subordinated notes issued by EUSHI Finance (collectively referred to as the “US Notes”) outstanding.

In compliance with Rule 13-01 of Regulation S-X, Emera is including summarized financial information for Emera, EUSHI and EUSHI Finance (together, the “Obligor Group”), on a combined basis after transactions and balances between the combined entities have been eliminated. Investments in and equity earnings of the Non-Guarantor Subsidiaries have been excluded from the summarized financial information.

Unless otherwise specified in a prospectus supplement that accompanies this prospectus, the net proceeds from the sale of the Debt Securities will be used for general corporate purposes including, without limitation, to repay existing indebtedness. We may invest funds that we do not immediately use in short-term marketable securities. We may from time to time offer Debt Securities and incur additional indebtedness other than through an offering under this prospectus and any applicable prospectus supplements.

There have been no material changes in the share and loan capital of Emera, on a consolidated basis, since June 30, 2025. See “Use of Proceeds”.

This section describes certain general terms and provisions of the Debt Securities. We will provide the particular terms and provisions of a series of Debt Securities and a description of how the general terms and provisions described below apply to that series in a prospectus supplement. Thus, for a description of the terms of a particular series of Debt Securities, you must refer to both the applicable prospectus supplement relating to that series and the description of the Debt Securities contained in this prospectus.

We may issue senior or subordinated Debt Securities under, in the case of senior Debt Securities, one or more senior debt indentures to be entered into among Emera, EUSHI Finance, EUSHI and the applicable senior notes trustees (the “Senior Indentures”), and, in the case of subordinated Debt Securities, under an indenture, dated June 18, 2024, between EUSHI Finance, the Guarantors and Equiniti Trust Company, LLC (as may be amended and/or supplemented from time to time, the “Subordinated Indenture” and together with the Senior Indenture, the “Indentures”). An indenture is a contract between a financial institution, acting on your behalf as trustee of the Debt Securities, and us.

The following description of the Indentures and the Debt Securities is a summary only. Please refer to the complete text of the provisions of the Debt Securities and the applicable Indenture, including the definition of certain terms in the applicable Indenture. It is the respective Indenture, and not this summary, that governs the rights of holders of Debt Securities. Capitalized terms that are used in this section and not defined have the meanings assigned to them in the Indenture. We have defined selected terms at the end of this section.

The Indentures provide that an unlimited amount of Debt Securities may be issued from time to time in one or more series and may be denominated and payable in U.S. dollars or any other currency; however, we may offer no more than US$3,000,000,000 (or the equivalent in non-U.S. Currency) aggregate principal amount of Debt Securities pursuant to this prospectus. The specific terms of any series of Debt Securities will be established at the time of issuance and will be described in the applicable prospectus supplement. These terms may include, but are not limited to, any of the following:

The general provisions of the Indentures do not contain any provisions that would limit our ability to incur indebtedness or that would afford holders protection in the event of a highly leveraged or similar transaction involving Emera.

Under each Indenture, we may have the ability, in addition to the ability to issue Debt Securities with terms different from those of other Debt Securities previously issued, without the consent of the holders, to reopen a previous issue of a series of Debt Securities and issue additional Debt Securities of such series.

We may issue under any senior debt indenture the Debt Securities that will constitute part of our senior debt. These senior Debt Securities will rank equally and pari passu with all of our other unsecured and unsubordinated debt.

We may issue under the Subordinated Indenture the Debt Securities that will constitute part of our subordinated debt. These Debt Securities will be subordinate and junior in right of payment, to the extent and in the manner set forth in the Subordinated Indenture, to all of our “senior indebtedness.”

The Debt Securities will be fully and unconditionally guaranteed by the Guarantors, on a joint and several basis, and such guarantees will rank equally with each such Guarantor’s other senior and/or subordinated unsecured obligations, as applicable, and will effectively be subordinated to all existing and future liabilities of each such Guarantor’s subsidiaries (other than EUSHI Finance and EUSHI).

Unless otherwise specified in an applicable prospectus supplement relating to a series of Debt Securities, the Indentures will not limit the amount of secured debt that Emera, EUSHI and EUSHI Finance may incur, as applicable, and the Debt Securities will effectively be subordinated in right of payment to any secured debt Emera, EUSHI and EUSHI Finance, may incur, as applicable, and to any of their respective secured obligations, in each case to the extent of the value of the collateral securing such debt or other obligations.

Debt Securities of a series may be issuable solely as registered Debt Securities issuable in denominations of US$2,000 and integral multiples of US$1,000 or in such other denominations as may be provided for by the terms of the Debt Securities of any particular series. The Indentures also provide that Debt Securities of a series may be issuable in global form, which are referred to as Global Securities. Debt Securities of any series will be exchangeable for other Debt Securities of the same series of any authorized denominations and of a like aggregate principal amount and tenor.

The Debt Securities may be presented for exchange as described above, and Debt Securities may be presented for registration of transfer (duly endorsed or accompanied by a written instrument of transfer), at the corporate trust office of the trustee or at the office of any transfer agent designated by us for such purpose with respect to any series of Debt Securities. No service charge will be made for any transfer or exchange of Debt Securities, but we may require payment of a sum sufficient to cover any tax or other governmental charge payable in connection therewith. We may at any time designate one or more successor or additional transfer agents with

respect to any series of Debt Securities and may from time to time rescind any such designation. We will be required to maintain a transfer agent in each Place of Payment for such series.

The Guarantors will fully and unconditionally guarantee, jointly and severally as primary obligors and not merely as sureties, on a senior and/or subordinated unsecured basis, the full and punctual payment when due, whether at stated maturity, by acceleration or otherwise, of all obligations of EUSHI Finance under the Debt Securities, whether for payment of principal of, or premium or interest on the Debt Securities, Additional Amounts, indemnification or otherwise. Each guarantee from a Guarantor will be limited to an amount not to exceed the maximum amount that can be guaranteed by the applicable Guarantor without rendering the guarantee, as it relates to that Guarantor, voidable under applicable law relating to fraudulent conveyance or fraudulent transfer or similar laws affecting the rights of creditors generally.

The Subordinated Indenture provides, with respect to any series of Outstanding Debt Securities thereunder, that the following shall constitute Events of Default:

The Senior Indenture provides, with respect to any series of Outstanding Debt Securities thereunder, that the following shall constitute Events of Default:

No Event of Default provided with respect to a particular series of Debt Securities necessarily constitutes an Event of Default with respect to any other series of Debt Securities.

If an Event of Default (other than an Event of Default related to certain events of bankruptcy, insolvency or reorganization) with respect to Debt Securities of any series at the time outstanding occurs and is continuing, then in every such case the trustee or the holders of not less than 25% in principal amount of the outstanding Debt Securities of that series may declare the principal amount, premium, if any, of all of the outstanding Debt Securities of that series and any accrued but unpaid interest thereon to be due and payable immediately, by a notice in writing to EUSHI Finance and the Guarantors (and to the trustee if given by holders or other act on the part of the trustee or any holder), and upon any such declaration such principal amount (or specified portion thereof), premium, if any, and any accrued but unpaid interest thereon shall become immediately due and payable. If an Event of Default related to certain events of bankruptcy, insolvency or reorganization occurs, then the principal amount of all of the outstanding Debt Securities, premium, if any, and any accrued but unpaid interest thereon shall ipso facto become and be immediately due and payable without any declaration, notice or other act on the part of the trustee or any holder.

Subject to the provisions of the Indentures relating to the duties of the trustee in case an Event of Default occurs and is continuing, the trustee shall be under no obligation to exercise any of the rights or powers vested in it by the Indentures at the request or direction of any of the holders of Debt Securities of any series pursuant to the Indenture, unless such holders shall have offered to the trustee security or indemnity satisfactory to the trustee against the costs, expenses and liabilities which might be incurred by it in compliance with such request or direction.

The holders of not less than a majority in principal amount of the outstanding Debt Securities of all series affected by an Event of Default shall 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 outstanding Debt Securities of such affected series, the Guarantee in respect thereof, provided in each case: (i) such direction shall not be in conflict with any rule of law or with the terms of the applicable Indenture, (ii) the trustee may take any other action deemed proper by the trustee which is not inconsistent with such direction, and (iii) the trustee need not take any action which might expose the trustee to personal liability or be unduly prejudicial to the holders of outstanding Debt Securities of such affected series not joining therein.

We and the trustee (and any applicable Guarantor, solely in the case of supplemental indentures amending any covenant, right or power of such Guarantor under the applicable Indenture) may modify and amend the applicable Indenture with the consent of the holders of not less than a majority in principal amount of all Outstanding Debt Securities under the applicable Indenture that are affected by such modification or amendment; provided that no such modification or amendment may, without the consent of the holder of each Outstanding Debt Security affected thereby, among other things:

The holders of a majority in principal amount of Outstanding Debt Securities under the Indenture affected thereby have the right to waive compliance by us with certain covenants.

We and the trustee (and any applicable Guarantor solely in the case of supplemental indentures establishing the form or terms of any series of Debt Securities pursuant to the applicable Indenture, adding or evidencing the succession of a Guarantor or amending any covenant, right or power of such Guarantor under the applicable Indenture) may modify and amend the applicable Indenture without the consent of any holder under the relevant Indenture, for any of the following purposes:

The Indentures provide that each Guarantor shall not be required to enter into any indenture supplemental to the Indenture, other than in the case of any supplemental indenture establishing the form or terms of any series of Debt Securities pursuant to the Indenture or amending any covenant, right or power of such Guarantor pursuant to the Indenture.

The Indentures provide that in determining whether the holders of the requisite principal amount of Debt Securities of a series then Outstanding under such Indenture have given any request, demand, authorization, direction, notice, consent or waiver thereunder:

The Indentures provide that EUSHI Finance and the Guarantors may not amalgamate or consolidate with or merge into any other Person and EUSHI Finance and the Guarantors may not convey, transfer, sell or lease its properties and assets substantially as an entirety to any Person, unless:

Notwithstanding the foregoing, any Subsidiary of Emera, other than EUSHI and EUSHI Finance, may consolidate with, merge into or transfer all or a portion of its properties or assets to Emera.

We may discharge certain obligations to holders of any series of Debt Securities issued under either Indenture which have not already been delivered to the trustee for cancellation and which have either become due and payable or are by their terms due and payable within one year (or scheduled for redemption within one year) by irrevocably depositing with the trustee trust funds in an amount sufficient to pay the entire indebtedness on such Debt Securities for principal (and premium, if any) and interest to the date of such deposit (if such Debt Securities have become due and payable) or to the Stated Maturity or Redemption Date, as the case may be.

We may, at our option and at any time, elect to have EUSHI Finance’s, as issuer, and each applicable Guarantor’s obligations discharged with respect to the Outstanding Debt Securities of or within any series, which we refer to as defeasance. Defeasance means that we shall be deemed to have paid and discharged the entire indebtedness represented by such Outstanding Debt Securities and to have satisfied our other obligations under the relevant Indenture with respect to such Debt Securities, except for:

We may, at our option and at any time, elect to be released from our obligations with respect to certain covenants that are described in either Indenture (including those described under “Merger, Consolidation or Amalgamation”), and we refer to this as “covenant defeasance,” and any omission to comply with such obligations thereafter shall not constitute a default or an Event of Default with respect to such Debt Securities.

Unless otherwise specified in the applicable Indenture, principal of (and premium, if any) and interest, if any, on any Debt Securities will be payable at an office or agency maintained by us in New York, New York, except that at our option, interest, if any, may be paid by:

Payment of any installment of interest on Debt Securities will be made to the Person in whose name such Debt Security is registered at the close of business on the Regular Record Date for such interest.

Any Paying Agent outside the United States and any other Paying Agent in the United States initially designated by us for the Debt Securities may be established for each series of Debt Securities. We may at any time designate additional Paying Agents or rescind the designation of any Paying Agent or approve a change in the office through which any Paying Agent acts, except that we will be required to maintain a Paying Agent in each Place of Payment for such series.

No resignation or removal of the trustee and no appointment of a successor trustee shall become effective until the acceptance of appointment by the successor trustee, in accordance with the applicable of the relevant Indenture. The trustee may resign at any time with respect to the Debt Securities of one or more series by giving written notice thereof to the Issuer. If the instrument of acceptance by a successor trustee is not delivered to the trustee within 30 days after the giving of such notice of resignation, the resigning trustee may petition any court of competent jurisdiction for the appointment of a successor trustee with respect to the Debt Securities of such series.

The Debt Securities of a series may be issued in whole or in part in the form of one or more Global Securities that will be deposited with, or on behalf of, a depositary for a series of Debt Securities. Global Securities may be issued in either temporary or permanent form. Unless otherwise provided for a series of Debt Securities, Debt Securities that are represented by a Global Security shall be issuable in denominations of $2,000 and integral multiples of $1,000 in excess thereof or in such other denominations as may be provided for by the terms of the Debt Securities of any particular series, and will be issued in registered form only, without coupons. Payments of principal of (and premium, if any) and interest, if any, on any Debt Securities represented by a Global Security will be made by the trustee to the depositary or its nominee.

The Indentures, the Guarantees and the Debt Securities shall be governed by and construed in accordance with the law of the State of New York. The Indentures are subject to the provisions of the Trust Indenture Act that are required to be part of the Indenture and shall, to the extent applicable, be governed by such provisions.

The Indentures provide that Emera has designated its subsidiary, EUSHI Finance, as its authorized agent for service of process in any suit, action or proceeding arising out of or relating to the Indenture and the Debt

Securities that may be instituted in any federal or state court located in the Borough of Manhattan, in the City of New York, or brought under United States federal or state securities laws or brought by the trustee, and Emera has irrevocably submitted to the jurisdiction of such courts.

We may sell Debt Securities at fixed prices or at non-fixed prices, such as prices determined by reference to the prevailing price of the specified securities in a specified market, at market prices prevailing at the time of sale or at prices to be negotiated with purchasers, which prices may vary as between purchasers and during the period of distribution of the securities. The applicable prospectus supplement will set forth the terms of the offering of the Debt Securities including the name or names of any underwriters, the purchase price of such Debt Securities and the proceeds to us from such sale, any underwriting discounts and other items constituting underwriters’ compensation, any public offering price and any discounts or concessions allowed or reallowed or paid to dealers. Only underwriters so named in the prospectus supplement are deemed to be underwriters in connection with the Debt Securities offered thereby.

If underwriters are used in the sale, the Debt Securities may be acquired by the underwriters for their own account and may be resold from time to time in one or more transactions, including negotiated transactions, at a fixed public offering price or at varying prices determined at the time of sale. The obligations of the underwriters to purchase such Debt Securities will be subject to certain conditions precedent, and the underwriters will be obligated to purchase all the Debt Securities of the series offered through the applicable prospectus supplement if any of such Debt Securities are purchased. Any public offering price and any discounts or concessions allowed or reallowed or paid to dealers may be changed from time to time.

We may also sell Debt Securities directly at such prices and upon such terms as agreed to by us and the purchaser or through agents designated by us from time to time. Any agent involved in the offering and sale of the Debt Securities in respect of which this prospectus is delivered will be named, and any commissions payable by us to such agent will be set forth, in the prospectus supplement. Unless otherwise indicated in the prospectus supplement, any agent is acting on a best efforts basis for the period of its appointment.

We may agree to pay the underwriters a commission for various services relating to the issue and sale of the Debt Securities offered hereby.

In connection with any offering of the Debt Securities, the underwriters or agents may over-allot or effect transactions which stabilize or maintain the market price of the Debt Securities offered at a level above that which might otherwise prevail in the open market. These transactions, if commenced, may be discontinued at any time.

Underwriters, dealers and agents who participate in the distribution of the Debt Securities may be entitled under agreements to be entered into with us to indemnification by us against certain liabilities, including liabilities under securities legislation, or to contribution with respect to payments which such underwriters, dealers or agents may be required to make in respect thereof. These underwriters, dealers and agents may be customers of, engage in transactions with or perform services for us in the ordinary course of business. Insofar as indemnification for liabilities arising under the U.S. Securities Act of 1933, as amended (the “U.S. Securities Act”) may be permitted to directors, officers and controlling persons of Emera, EUSHI, or EUSHI Finance, such issuers have been advised that, in the opinion of the SEC, such indemnification is against public policy as expressed in the U.S. Securities Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the issuers of expenses incurred or paid by a director, officer or controlling person of the issuers in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the issuers will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the U.S. Securities Act and will be governed by the final adjudication of such issue.

Each series of the Debt Securities will be a new issue of securities with no established trading market. Unless otherwise specified in an applicable prospectus supplement relating to a series of Debt Securities, the Debt Securities will not be listed on any securities or stock exchange or on any automated dealer quotation system. Some broker-dealers may make a market in the Debt Securities, but they will not be obligated to do so and may discontinue any market-making activities at any time without notice. There may not be a trading market for the Debt Securities and no assurances can be given as to the liquidity of the trading market, if any, for the Debt Securities.

A prospectus supplement may describe any material Canadian federal income tax consequences of the acquisition, ownership and disposition of Debt Securities by an initial investor, including any such consequences to an investor who is not a resident of Canada (for purposes of the Income Tax Act (Canada) and any applicable income tax convention).

A prospectus supplement may describe any material U.S. federal income tax consequences of the acquisition, ownership and disposition of Debt Securities by an initial investor, including, to the extent applicable, any such consequences relating to Debt Securities payable in a currency other than U.S. dollars, issued with original issue discount for U.S. federal income tax purposes, or containing any early redemption provisions or other special terms.

The validity of the Debt Securities and the related Guarantees will be passed on for us by Davis Polk & Wardwell LLP, New York, New York.
