[424B5] TORONTO DOMINION BANK Prospectus Supplement (Debt Securities)

Rhea-AI Filing Summary

The Toronto-Dominion Bank is offering Senior Medium-Term Notes, Series F denominated in U.S. dollars. The notes carry standard minimum denominations of US$2,000 (and integral multiples of US$1,000 thereafter), pay interest semi‑annually under a 30/360 day count, and will settle through DTC global facilities including Euroclear and Clearstream. The offering is not exchange‑listed and holders have no put right; optional redemption by the bank is described but holders’ optional redemption is not applicable. TD Securities (USA) LLC, an affiliate, is a joint book‑running manager and the offering will conform to FINRA Rule 5121 conflict‑of‑interest requirements.

Crucially, the notes are defined as bail‑inable under the CDIC Act and may be converted, in whole or in part, into common shares of the bank (or an affiliate) pursuant to Canadian bail‑in powers, with resulting variation or extinguishment of debt. The offering is concurrent with several other senior and floating‑rate series; settlement of each series is independent.

Positive

• U.S. dollar denomination and DTC global settlement facilitate broad institutional distribution
• Standard market mechanics: semi‑annual interest and 30/360 day count provide predictable cash flows
• Minimum denominations of US$2,000 support liquidity for retail and institutional investors

Negative

• Notes are bail‑inable under the CDIC Act, allowing conversion into common shares and potential extinguishment of debt
• Not listed on any exchange, which may limit secondary market visibility and price discovery
• Affiliate manager conflict (TD Securities (USA) LLC) triggers FINRA Rule 5121 constraints on sales to discretionary accounts

Insights

Debt Capital Markets Analyst

TL;DR: Senior U.S. dollar notes with standard market mechanics but carry Canadian bail‑in conversion risk.

The issuance uses conventional settlement and interest mechanics: U.S. dollar denomination, US$2,000 minimum, semi‑annual coupons on a 30/360 basis and DTC global clearance, which supports institutional distribution and secondary trading via Euroclear/Clearstream.

However, the classification as bail‑inable under the CDIC Act creates a structural credit‑event dependency where principal and accrued interest may be converted into common shares. Monitor applicable regulatory actions and any conversion triggers during the life of the notes.

Regulatory Counsel (Banking)

TL;DR: Legal framework imposes a non‑payment resolution path under Canadian law, not a contractual default remedy.

The notes explicitly reference subsection 39.2(2.3) of the CDIC Act and related Ontario/federal law, permitting conversion or extinguishment by statutory exercise of bail‑in powers. Holders are deemed to consent to receiving common shares for converted amounts.

Key dependencies include future regulatory determinations and any statutory amendments; watch near‑term regulatory communications or exercise of resolution powers which would materially affect claim recovery profiles.

Agreement with Respect to the Exercise of Canadian Bail-in Powers

By its acquisition of an interest in any Note, each holder or beneficial owner of that Note is deemed to (1) agree to be bound, in respect of the Notes, by the CDIC Act, including the conversion of the Notes, in whole or in part — by means of a transaction or series of transactions and in one or more steps — into common shares of the Bank or any of its affiliates under subsection 39.2(2.3) of the CDIC Act and the variation or extinguishment of the Notes in consequence, and by the application of the laws of the Province of Ontario and the federal laws of Canada applicable therein in respect of the operation of the CDIC Act with respect to the Notes; (2) attorn and submit to the jurisdiction of the courts in the Province of Ontario with respect to the CDIC Act and those laws; (3) have represented and warranted that TD has not directly or indirectly provided financing to the holder or beneficial owner of the Notes for the express purpose of investing in the Notes; and (4) acknowledge and agree that the terms referred to in clauses (1) and (2), above, are binding on that holder or beneficial owner despite any provisions in the indenture or the Notes, any other law that governs the Notes and any other agreement, arrangement or understanding between that holder or beneficial owner and the Bank with respect to the Notes.

Holders and beneficial owners of Notes will have no further rights in respect of their bail-inable notes to the extent those bail-inable notes are converted in a bail-in conversion, other than those provided under the bail-in regime, and by its acquisition of an interest in any Note, each holder or beneficial owner of that Note is deemed to irrevocably consent to the converted portion of the principal amount of that Note and any accrued and unpaid interest thereon being deemed paid in full by the Bank by the issuance of common shares of the Bank (or, if applicable, any of its affiliates) upon the occurrence of a bail-in conversion, which bail-in conversion will occur

PS-4

without any further action on the part of that holder or beneficial owner or the trustee; provided that, for the avoidance of doubt, this consent will not limit or otherwise affect any rights that holders or beneficial owners may have under the bail-in regime.

See “Description of the Debt Securities — Terms Specific to Senior Debt Securities — Special Provisions Related to Bail-inable Debt Securities” in the accompanying prospectus supplement and base prospectus for a description of the provisions applicable to the Notes as a result of Canadian bail-in powers.

Additional Amounts

All payments of principal and interest and other amounts payable in respect of the Notes by us will be made without us making any withholding of or deduction for, or on account of, any present or future taxes, duties, assessments or governmental charges of whatever nature (“Taxes”), unless the withholding or deduction of such Taxes is required or authorized by law or the administration thereof. In that event, we will, subject to certain exceptions and limitations set forth below, pay such additional amounts (“Additional Amounts”) to the holder or beneficial owner of any Note as may be necessary in order that every net payment of the principal of and interest on such Note and any other amounts payable on such Note, after any withholding or deduction for Taxes imposed or levied by or on behalf of Canada or any political subdivision or taxing authority thereof or therein having the power to tax (each a “Taxing Jurisdiction”) (and Taxes imposed or levied by a Taxing Jurisdiction on such Additional Amounts), will not be less than the amount such holder or beneficial owner would have received if such Taxes imposed or levied by or on behalf of a Taxing Jurisdiction had not been withheld or deducted. We will not, however, be required to make any payment of Additional Amounts to any holder or beneficial owner for or on account of:

• any Taxes that would not have been so imposed but for a present or former connection (including, without limitation, carrying on business in a Taxing Jurisdiction or having a permanent establishment or fixed base in a Taxing Jurisdiction) between such holder or beneficial owner of a Note (or between a fiduciary, settlor, beneficiary, member or shareholder of, or possessor of power over, such holder or beneficial owner, if such holder or beneficial owner is an estate, trust, partnership, limited liability company or corporation) and a Taxing Jurisdiction, other than merely holding such Note or receiving payments with respect to such Note;

• any estate, inheritance, gift, sales, transfer or personal property Tax or any similar Tax with respect to a Note;

• any Tax imposed by reason that such holder or beneficial owner of a Note, or other person (including a partnership) that receives or is entitled to payment under the Note, does not deal at arm’s length within the meaning of the Income Tax Act (Canada) with us or is, or does not deal at arm’s length with any person who is, a “specified shareholder” (as defined in subsection 18(5) of the Income Tax Act (Canada)) of us, or as a result of us or any payer being a “specified entity” (as defined in subsection 18.4 (1) of the Income Tax Act (Canada)) in respect of the holder, beneficial owner, or other person (including a partnership) that receives or is entitled to payments on the Note;

• any Tax that is levied or collected otherwise than by withholding from payments on or in respect of a Note;

• any Tax required to be withheld by any paying agent from any payment on a Note, if such payment can be made without such withholding by at least one other paying agent;

• any Tax that would not have been imposed but for the failure of a holder or beneficial owner of a Note to comply with certification, identification, declaration, information or other reporting requirements, if such compliance is required by a Taxing Jurisdiction (including where required by statute, treaty, regulation or administrative pronouncement) as a precondition to relief or exemption from such Tax;

• any Tax which would not have been imposed but for the presentation of a Note (where presentation is required) for payment on a date more than 30 days after (i) the date on which such payment became due and payable or (ii) the date on which payment thereof is duly provided for, whichever occurs later;

PS-5

• any withholding or deduction imposed pursuant to (i) Sections 1471 to 1474 of the U.S. Internal Revenue Code of 1986, as amended (“FATCA”), or any successor version thereof, or any similar legislation imposed by any other governmental authority, (ii) any treaty, law, regulation or other official guidance enacted by Canada implementing FATCA or an intergovernmental agreement with respect to FATCA or any similar legislation imposed by any other governmental authority, or (iii) any agreement between us and the United States or any authority thereof implementing FATCA; or

• any combination of the items listed above;

nor shall Additional Amounts be paid with respect to any payment on a Note to a holder who is a fiduciary or partnership or any person other than the sole beneficial owner of such payment to the extent a beneficiary or settlor with respect to such fiduciary, a member of such partnership or such beneficial owner would not have been entitled to the Additional Amounts had such beneficiary, settlor, member or beneficial owner held its interest in the Note directly. For the purposes of this discussion of “Additional Amounts”, the term “person” shall include a partnership.

In addition, no Additional Amounts will be payable under the provisions described above to any holder or beneficial owner of a Note on account of Taxes that are in excess of the Taxes that would have been imposed if, at all relevant times, such holder or beneficial owner of a Note were a resident of the United States for purposes of, and was entitled to all of the benefits of, the United States-Canada Income Tax Convention (1980), as amended, including any protocols thereto (the “Convention”). As a result of the limitation on the payment of Additional Amounts discussed in the preceding sentence, the Additional Amounts received by certain holders or beneficial owners of Notes may be less than the amount of Canadian taxes withheld or deducted and, accordingly, the net amount received by such holders or beneficial owners of Notes will be less than the amount such holders or beneficial owners would have received had there been no such withholding or deduction in respect of Canadian taxes. Any prospective investor that is not a resident of the United States for purposes of, and entitled to all of the benefits of, the Convention should consult its tax advisor regarding the possibility of any future Canadian withholding tax that would reduce its return from the Notes.

Optional Redemption

The Notes may be redeemed at any time prior to maturity, as a whole or in part, at our option, at any time and from time to time on at least 10 days’, but not more than 60 days’, prior notice provided (or otherwise transmitted in accordance with DTC procedures) to each holder of the Notes to be redeemed. The redemption price will be calculated by us and will be equal to the sum of (i) 100% of the principal amount of the Notes to be redeemed; (ii) the Make-Whole Amount (as defined below), if any, with respect to such Notes; and (iii) accrued and unpaid interest on such Notes to, but excluding, the date of redemption.

“Make-Whole Amount” means, in connection with any optional redemption of the Notes, the excess, if any, of: (i) the aggregate present value as of the date of such redemption of each dollar of principal being redeemed and the amount of interest (exclusive of interest accrued to the date of redemption) that would have been payable in respect of each such dollar if such redemption had not been made, determined by discounting, on a semi-annual basis, such principal and interest at the Reinvestment Rate (as defined below) (determined on the third business day preceding the applicable redemption date) from the respective dates on which such principal and interest would have been payable if such redemption had not been made, over (ii) the aggregate principal amount of the Notes being redeemed.

“Reinvestment Rate” means the yield on Treasury securities at a constant maturity corresponding to the remaining life (as of the date of redemption, and rounded to the nearest month) to stated maturity (the “Treasury Yield”), plus     %. For purposes hereof, the Treasury Yield shall be equal to the arithmetic mean of the yields published in the Statistical Release (as defined below) under the heading which represents the average for

PS-6

the immediately preceding week for “U.S. Government Securities—Treasury Constant Maturities” with a maturity equal to such remaining life; provided, that if no published maturity exactly corresponds to such remaining life, then the Treasury Yield shall be interpolated or extrapolated on a straight-line basis from the arithmetic means of the yields for the next shortest and next longest published maturities. For purposes of calculating the Reinvestment Rate, the most recent Statistical Release published prior to the third business day preceding the applicable redemption date shall be used. If the format or content of the Statistical Release changes in a manner that precludes determination of the Treasury Yield in the above manner, then the Treasury Yield shall be determined in the manner that most closely approximates the above manner, as reasonably determined by us.

“Statistical Release” means the Data Download Program designated as “H.15” or any successor publication which is published weekly by the Board of Governors of the Federal Reserve System and which reports yields on actively traded United States government securities adjusted to constant maturities, or, if such statistical release is not published at the time of any determination under the senior indenture, then such other reasonably comparable index which shall be designated by us.

On and after the redemption date, interest will cease to accrue on the Notes or any portion of the Notes called for redemption, unless we default in the payment of the redemption price and accrued interest. On or before the redemption date, we will deposit with our paying agent or the trustee money sufficient to pay the redemption price of and accrued interest on the Notes to be redeemed on that date.

Any redemption or notice may, at our discretion, be subject to one or more conditions precedent and, at our discretion, the redemption date may be delayed until such time as any or all such conditions precedent included at our discretion shall be satisfied (or waived by us) or the redemption date may not occur and such notice may be rescinded if all such conditions precedent included at our discretion shall not have been satisfied (or waived by us).

In the case of any partial redemption, selection of the Notes to be redeemed will be made in accordance with applicable procedures of DTC.

Redemption for Tax Reasons

We may redeem the Notes, in whole but not in part, at our option at any time prior to maturity, upon the giving of a notice of redemption as described below, if:

(i) as a result of any change (including any announced prospective change) in or amendment to the laws or treaties (or any rules, regulations, rulings or administrative pronouncements thereunder) of Canada or of any political subdivision or taxing authority thereof or therein affecting taxation, or any change in official position regarding the application or interpretation of such laws, treaties, rules, regulations, rulings or administrative pronouncements (including a holding by a court of competent jurisdiction), which change or amendment is announced or becomes effective on or after May 27, 2025, in the written opinion of our legal counsel of recognized standing, we have or will become obligated to pay, on the next succeeding date on which interest is due, Additional Amounts (assuming, in the case of any announced prospective change, that such announced change will become effective as of the date specified in such announcement and in the form announced); or

(ii) on or after May 27, 2025 any action has been taken by any taxing authority of, or any decision has been rendered by a court of competent jurisdiction in, Canada or any political subdivision or taxing authority thereof or therein, including any of those actions specified in the paragraph immediately above, whether or not such action was taken or decision was rendered with respect to us, or any change, amendment, application or interpretation shall be officially proposed, which, in any such case, in the written opinion of our legal counsel of recognized standing, will result in our becoming obligated to pay, on the next succeeding date on which interest is due, Additional Amounts (assuming, in the case of any announced prospective change, that such announced change will become effective as of the date specified in such announcement and in the form announced);

PS-7

and, in any such case, we in our business judgment determine that such obligation cannot be avoided by the use of reasonable measures available to us. For the avoidance of doubt, reasonable measures do not include a change in the terms of the Notes or a substitution of the issuer.

Prior to the giving of any notice of redemption pursuant to the above paragraph, we will deliver to the trustee:

• a certificate stating that we are entitled to effect such redemption and setting forth a statement of facts showing that the conditions precedent to our right to so redeem have occurred; and

• an opinion of counsel prepared in accordance with the terms of the indenture.

Any Notes redeemed for tax reasons will be redeemed at 100% of their principal amount together with interest accrued up to, but excluding, the redemption date. Notice of redemption will be given not less than 10 nor more than 60 days prior to the date fixed for redemption, which date and the applicable redemption price will be specified in the notice.

Any such redemption of bail-inable notes will require the prior approval of the Superintendent of Financial Institutions (Canada) if the redemption would result in TD not meeting the Total Loss Absorbing Capacity (“TLAC”) requirements applicable to it pursuant to the Office of the Superintendent of Financial Institutions guideline on TLAC.

For a discussion of certain material U.S. federal income tax consequences of owning the Notes, please see the section “Tax Consequences — United States Taxation” in the accompanying prospectus supplement and base prospectus. The following discussion supplements and, to the extent inconsistent therewith, replaces the discussion in such section.

The initial offering price for the Notes will include amounts attributable to unpaid interest accrued from June 3, 2025 (“pre-issuance accrued interest”). For U.S. federal income tax purposes, we intend to treat the Notes as having been purchased for a price that does not include any pre-issuance accrued interest. If the Notes are so treated, the portion of the first stated interest payment equal to the pre-issuance accrued interest should be treated a non-taxable return of pre-issuance accrued interest and should not be taxable as interest on the Notes.

CANADIAN FEDERAL INCOME TAX CONSIDERATIONS

For a discussion of certain material Canadian federal income tax consequences of owning the Notes, please see the section “Tax Consequences — Canadian Taxation” in the accompanying prospectus supplement and base prospectus.

BENEFIT PLAN INVESTOR CONSIDERATIONS

For a discussion of certain considerations in connection with owning the Notes with plan assets, please see the section “Benefit Plan Investor Considerations” in the accompanying prospectus supplement and base prospectus.

UNDERWRITING (CONFLICTS OF INTEREST)

On     , 2025, we entered into a Terms Agreement with the agents pursuant to the Distribution Agreement, dated February 26, 2025, between us and TD Securities (USA) LLC for the purchase and sale of the Notes. We have agreed to sell to each of the agents, and each of the agents has severally agreed to purchase from us, as principal, the principal amount of the Notes shown opposite its name at the public offering price set forth above, subject to the terms and conditions set forth in the Terms Agreement and the Distribution Agreement.

Agent		Principal Amount of Notes
TD Securities (USA) LLC		US$
		US$
		US$
		US$
Total		US$

The agents initially propose to offer the Notes to the public at the public offering price set forth on the cover page of this pricing supplement and may offer the Notes to certain dealers at the public offering price less a concession not in excess of     % of the principal amount of the Notes. The agents may allow, and such dealers may reallow, a concession not in excess of     % of the principal amount of the Notes on sales to certain dealers. After the initial offering of the Notes, the public offering price and other selling terms may from time to time be changed. The offering of the Notes by the agents is subject to receipt and acceptance and subject to the agents’ right to reject any order in whole or in part.

We estimate that the total offering expenses for the Notes and the Concurrent Offerings, excluding underwriting commissions, will be approximately US$    .

We have agreed to indemnify the several agents against certain liabilities, including liabilities under the Securities Act of 1933, as amended.

To the extent any agent that is not a U.S. registered broker-dealer intends to effect any offers or sales of any notes in the United States, it will do so through one or more U.S. registered broker-dealers in accordance with the applicable U.S. securities laws and regulations.

The agents and their respective affiliates are full service financial institutions engaged in various activities, which may include securities trading, commercial and investment banking, financial advisory, investment management, investment research, principal investment, hedging, financing and brokerage activities. Certain of the agents and their respective affiliates have, from time to time, performed, and may in the future perform, various financial advisory and investment banking services for the Bank, for which they received or will receive customary fees and expenses.

In the ordinary course of their various business activities, the agents and their respective affiliates may make or hold a broad array of investments, including serving as counterparties to certain derivative and trading arrangements, and actively trade debt and equity securities (or related derivative securities) and financial instruments (including bank loans) for their own account and for the accounts of their customers, and such investment and securities activities may involve securities and/or instruments of the Bank. If any of the agents or their respective affiliates has a lending relationship with us, certain of those agents or their affiliates routinely hedge, and certain of those agents or their affiliates may hedge, their credit exposure to us consistent with their customary risk management policies. Typically, these agents and their affiliates would hedge such exposure by entering into transactions which consist of either the purchase of credit default swaps or the creation of short positions in our securities, including potentially the Notes. Any such credit default swaps or short positions could adversely affect future trading prices of the Notes. The agents and their respective affiliates may also make investment recommendations and/or publish or express independent research views in respect of such securities or instruments and may at any time hold, or recommend to clients that they acquire, long and/or short positions in such securities and instruments.

PS-10

It is expected that delivery of the Notes will be made against payment therefor on or about      , 2025, which is the    business day following the date hereof (such settlement cycle being referred to as “T+ ”). Under Rule 15c6-1 under the Exchange Act, trades in the secondary market generally are required to settle in one business day unless the parties to any such trade expressly agree otherwise. Accordingly, purchasers who wish to trade the Notes prior to the business day immediately before settlement will be required, by virtue of the fact that the Notes initially will settle in T+ , to specify an alternative settlement cycle at the time of any such trade to prevent a failed settlement.

Conflicts of Interest

TD Securities (USA) LLC is our affiliate. Accordingly, the offering of the Notes will conform to the requirements of FINRA Rule 5121. TD Securities (USA) LLC is not permitted to sell the Notes to an account over which it exercises discretionary authority without the prior specific written approval of the account holder.
