· Enhanced Return Potential — If the Final Underlier Value is greater than the Lookback Underlier Value, at maturity, investors will receive a return equal to 119.25% of the Underlier Return.

· Contingent Return of Principal at Maturity — If the Final Underlier Value is less than or equal to the Lookback Underlier Value, but is greater than or equal to the Buffer Value (90% of the Lookback Underlier Value), at maturity, investors will receive the principal amount of their Notes. If the Final Underlier Value is less than the Buffer Value, at maturity, investors will lose 1% of the principal amount of their Notes for each 1% that the Final Underlier Value is less than the Lookback Underlier Value in excess of the Buffer Percentage of 10%.

· The Notes do not pay interest.

· Any payments on the Notes are subject to our credit risk.

· The Notes will not be listed on any securities exchange.

⁽¹⁾ We or one of our affiliates may pay varying selling concessions of up to $2.50 per $1,000 principal amount of Notes in connection with the distribution of the Notes to other registered broker-dealers. Certain dealers who purchase the Notes for sale to certain fee-based advisory accounts may forgo some or all of their underwriting discount or selling concessions. The public offering price for investors purchasing the Notes in these accounts may be between $997.50 and $1,000.00 per $1,000 principal amount of Notes.

HYPOTHETICAL RETURNS

The table and examples set forth below illustrate hypothetical payments at maturity for hypothetical performance of the Underlier, based on the Buffer Value of 90% of the Lookback Underlier Value, the Participation Rate of 119.25% and the Buffer Percentage of 10%. The table and examples are only for illustrative purposes and may not show the actual return applicable to investors.

Hypothetical Underlier Return	Payment at Maturity per $1,000 Principal Amount of Notes	Payment at Maturity as Percentage of Principal Amount
50.00%	$1,596.250	159.6250%
40.00%	$1,477.000	147.7000%
30.00%	$1,357.750	135.7750%
20.00%	$1,238.500	123.8500%
10.00%	$1,119.250	111.9250%
5.00%	$1,059.625	105.9625%

0.00%	$1,000.000	100.0000%

-10.00%	$1,000.000	100.0000%
-20.00%	$900.000	90.0000%
-30.00%	$800.000	80.0000%
-40.00%	$700.000	70.0000%
-50.00%	$600.000	60.0000%
-60.00%	$500.000	50.0000%
-70.00%	$400.000	40.0000%
-80.00%	$300.000	30.0000%
-90.00%	$200.000	20.0000%
-100.00%	$100.000	10.0000%

Example 1 —	The value of the Underlier increases from the Lookback Underlier Value to the Final Underlier Value by 2%.
	Underlier Return:	2%
	Payment at Maturity:	$1,000 + ($1,000 × 2% × 119.25%) = $1,000 + $23.85 = $1,023.85
	In this example, the payment at maturity is $1,023.85 per $1,000 principal amount of Notes, for a return of 2.385%. Because the Final Underlier Value is greater than the Lookback Underlier Value, investors receive a return equal to 119.25% of the Underlier Return.

P-6 RBC Capital Markets, LLC

Lookback Entry Enhanced Return Buffer Notes Linked to the S&P 500^® Futures Excess Return Index

Example 2 —	The value of the Underlier decreases from the Lookback Underlier Value to the Final Underlier Value by 5% (i.e., the Final Underlier Value is below the Lookback Underlier Value but above the Buffer Value).
	Underlier Return:	-5%
	Payment at Maturity:	$1,000
	In this example, the payment at maturity is $1,000 per $1,000 principal amount of Notes, for a return of 0%. Because the Final Underlier Value is greater than the Buffer Value, investors receive a full return of the principal amount of their Notes.

Example 3 —	The value of the Underlier decreases from the Lookback Underlier Value to the Final Underlier Value by 50% (i.e., the Final Underlier Value is below the Buffer Value).
	Underlier Return:	-50%
	Payment at Maturity:	$1,000 + [$1,000 × (-50% + 10%)] = $1,000 – $400 = $600
	In this example, the payment at maturity is $600 per $1,000 principal amount of Notes, representing a loss of 40% of the principal amount. Because the Final Underlier Value is less than the Buffer Value, investors do not receive a full return of the principal amount of their Notes.

Investors in the Notes could lose some or a substantial portion of the principal amount of their Notes at maturity.

SELECTED RISK CONSIDERATIONS

An investment in the Notes involves significant risks. We urge you to consult your investment, legal, tax, accounting and other advisers before you invest in the Notes. Some of the risks that apply to an investment in the Notes are summarized below, but we urge you to read also the “Risk Factors” sections of the accompanying prospectus, prospectus supplement and product supplement. You should not purchase the Notes unless you understand and can bear the risks of investing in the Notes.

Risks Relating to the Terms and Structure of the Notes

· You May Lose a Substantial Portion of the Principal Amount at Maturity — If the Final Underlier Value is less than the Buffer Value, you will lose 1% of the principal amount of your Notes for each 1% that the Final Underlier Value is less than the Lookback Underlier Value in excess of the Buffer Percentage. You could lose some or a substantial portion of your principal amount at maturity.

· The Lookback Underlier Value Will Not Be Known until the Lookback Observation End Date — The Lookback Underlier Value of the Underlier will be the lowest closing value of the Underlier on any scheduled trading day during the Lookback Observation Period. Accordingly, you will not know the Lookback Underlier Value for a period of time after the Trade Date. There can be no assurance that the closing value of the Underlier will decline on any scheduled trading day during the Lookback Observation Period below the closing value of the Underlier on the Trade Date.

· The Notes Do Not Pay Interest, and Your Return on the Notes May Be Lower Than the Return on a Conventional Debt Security of Comparable Maturity — There will be no periodic interest payments on the Notes as there would be on a conventional fixed-rate or floating-rate debt security having the same maturity. The return that you will receive on the Notes, which could be negative, may be less than the return you could earn on other investments. Even if your return is positive, your return may be less than the return you would earn if you purchased one of our conventional senior interest-bearing debt securities.

· Payments on the Notes Are Subject to Our Credit Risk, and Market Perceptions about Our Creditworthiness May Adversely Affect the Market Value of the Notes — The Notes are our senior unsecured debt securities, and your receipt of any amounts due on the Notes is dependent upon our ability to pay our obligations as they come due. If we were to default on our payment obligations, you may not receive any amounts owed to you under the Notes and you could lose your entire investment. In addition, any negative changes in market perceptions about our creditworthiness may adversely affect the market value of the Notes.

· Any Payment on the Notes Will Be Determined Based on the Closing Values of the Underlier on the Dates Specified — Any payment on the Notes will be determined based on the closing values of the Underlier on the dates specified. You will not benefit from any more favorable value of the Underlier determined at any other time.

· The U.S. Federal Income Tax Consequences of an Investment in the Notes Are Uncertain — There is no direct legal authority regarding the proper U.S. federal income tax treatment of the Notes, and significant aspects of the tax treatment of the Notes are uncertain. You should review carefully the section entitled “United States Federal Income Tax Considerations” herein, in combination with the section entitled “United States Federal Income Tax Considerations” in the accompanying product supplement, and consult your tax adviser regarding the U.S. federal income tax consequences of an investment in the Notes.

Risks Relating to the Initial Estimated Value of the Notes and the Secondary Market for the Notes

· There May Not Be an Active Trading Market for the Notes; Sales in the Secondary Market May Result in Significant Losses — There may be little or no secondary market for the Notes. The Notes will not be listed on any securities exchange. RBCCM and our other affiliates may make a market for the Notes; however, they are not required to do so and, if they choose to do so, may stop any market-making activities at any time. Because other dealers are not likely to make a secondary market for the Notes, the price at which you may be able to trade your Notes is likely to depend on the price, if any, at which RBCCM or any of our other affiliates is willing to buy the Notes. Even if a secondary

P-8 RBC Capital Markets, LLC

Lookback Entry Enhanced Return Buffer Notes Linked to the S&P 500^® Futures Excess Return Index

market for the Notes develops, it may not provide enough liquidity to allow you to easily trade or sell the Notes. We expect that transaction costs in any secondary market would be high. As a result, the difference between bid and ask prices for your Notes in any secondary market could be substantial. If you sell your Notes before maturity, you may have to do so at a substantial discount from the price that you paid for them, and as a result, you may suffer significant losses. The Notes are not designed to be short-term trading instruments. Accordingly, you should be able and willing to hold your Notes to maturity.

· The Initial Estimated Value of the Notes Will Be Less Than the Public Offering Price — The initial estimated value of the Notes will be less than the public offering price of the Notes and does not represent a minimum price at which we, RBCCM or any of our other affiliates would be willing to purchase the Notes in any secondary market (if any exists) at any time. If you attempt to sell the Notes prior to maturity, their market value may be lower than the price you paid for them and the initial estimated value. This is due to, among other things, changes in the value of the Underlier, the internal funding rate we pay to issue securities of this kind (which is lower than the rate at which we borrow funds by issuing conventional fixed rate debt) and the inclusion in the public offering price of the underwriting discount, the referral fee, our estimated profit and the estimated costs relating to our hedging of the Notes. These factors, together with various credit, market and economic factors over the term of the Notes, are expected to reduce the price at which you may be able to sell the Notes in any secondary market and will affect the value of the Notes in complex and unpredictable ways. Assuming no change in market conditions or any other relevant factors, the price, if any, at which you may be able to sell your Notes prior to maturity may be less than your original purchase price, as any such sale price would not be expected to include the underwriting discount, the referral fee, our estimated profit or the hedging costs relating to the Notes. In addition, any price at which you may sell the Notes is likely to reflect customary bid-ask spreads for similar trades. In addition to bid-ask spreads, the value of the Notes determined for any secondary market price is expected to be based on a secondary market rate rather than the internal funding rate used to price the Notes and determine the initial estimated value. As a result, the secondary market price will be less than if the internal funding rate were used.

· The Initial Estimated Value of the Notes Is Only an Estimate, Calculated as of the Trade Date — The initial estimated value of the Notes is based on the value of our obligation to make the payments on the Notes, together with the mid-market value of the derivative embedded in the terms of the Notes. See “Structuring the Notes” below. Our estimate is based on a variety of assumptions, including our internal funding rate (which represents a discount from our credit spreads), expectations as to dividends, interest rates and volatility and the expected term of the Notes. These assumptions are based on certain forecasts about future events, which may prove to be incorrect. Other entities may value the Notes or similar securities at a price that is significantly different than we do.

The value of the Notes at any time after the Trade Date will vary based on many factors, including changes in market conditions, and cannot be predicted with accuracy. As a result, the actual value you would receive if you sold the Notes in any secondary market, if any, should be expected to differ materially from the initial estimated value of the Notes.

Risks Relating to Conflicts of Interest and Our Trading Activities

· Our and Our Affiliates’ Business and Trading Activities May Create Conflicts of Interest — You should make your own independent investigation of the merits of investing in the Notes. Our and our affiliates’ economic interests are potentially adverse to your interests as an investor in the Notes due to our and our affiliates’ business and trading activities, and we and our affiliates have no obligation to consider your interests in taking any actions that might affect the value of the Notes. Trading by us and our affiliates may adversely affect the value of the Underlier and the market value of the Notes. See “Risk Factors—Risks Relating to Conflicts of Interest” in the accompanying product supplement.

· RBCCM’s Role as Calculation Agent May Create Conflicts of Interest — As Calculation Agent, our affiliate, RBCCM, will determine any values of the Underlier and make any other determinations necessary to calculate any payments on the Notes. In making these determinations, the Calculation Agent may be required to make discretionary judgments, including those described under “—Risks Relating to the Underlier” below. In making these discretionary judgments, the economic interests of the Calculation Agent are potentially adverse to your interests as an investor in the Notes, and any of these determinations may adversely affect any payments on the Notes. The Calculation Agent will have no obligation to consider your interests as an investor in the Notes in making any determinations with respect to the Notes.

P-9 RBC Capital Markets, LLC

Lookback Entry Enhanced Return Buffer Notes Linked to the S&P 500^® Futures Excess Return Index

Risks Relating to the Underlier

· You Will Not Have Any Rights to the Futures Contracts Included in the Underlier or the Securities Included in the Reference Index — As an investor in the Notes, you will not have voting rights or rights to receive dividends or other distributions or any other rights with respect to the futures contracts included in the Underlier or the securities included in the S&P 500^® Index (the “Reference Index”).

· The Underlier Reflects the Price Return of the Futures Contracts Composing the Underlier, Not the Total Return — The return on the Notes is based on the performance of the Underlier, which reflects changes in the market prices of the futures contracts composing the Underlier and positive or negative yields associated with rolling those futures contracts. The Underlier is not a “total return” index that, in addition to reflecting those price and roll returns, would also reflect interest on a hypothetical cash position collateralizing the futures contracts composing the Underlier.

· The Performance of the Underlier Will Differ from the Performance of the Reference Index — A variety of factors can lead to a disparity between the performance of an equity index futures contract and the index referenced by those futures contracts, including the expected dividend yields of the equity securities included in that index, an implicit financing cost associated with the futures contract and policies of the exchange on which the futures contracts are traded, such as margin requirements. A decline in expected dividends yields or an increase in margin requirements may adversely affect the performance of the Underlier. In addition, the implicit financing cost will negatively affect the performance of the Underlier, with a greater negative effect when market interest rates are higher. During periods of high market interest rates, the Underlier is likely to underperform the Reference Index, perhaps significantly.

· Negative Roll Returns Associated with the Futures Contracts Composing the Underlier May Adversely Affect the Level of the Underlier and the Value of the Notes — Unlike equity securities, the futures contracts composing the Underlier, by their terms, have stated expirations. As the futures contracts composing the Underlier approach expiration, they are replaced by contracts of the same series that have a later expiration. For example, a futures contract notionally purchased and held in June may specify a September expiration date. As time passes, the contract expiring in September is replaced by a contract for delivery in December. This is accomplished by notionally selling the September contract and notionally purchasing the December contract. This process is referred to as “rolling.” Excluding other considerations, if prices are higher in the distant delivery months than in the nearer delivery months, the notional purchase of the December contract would take place at a price that is higher than the price of the September contract, thereby creating a negative “roll return.” Negative roll returns adversely affect the returns on the futures contracts composing the Underlier and, therefore, the value of the Underlier and any payments on, and the value of, the Notes. Because of the potential effects of negative roll returns, it is possible for the value of the Underlier to decrease significantly over time, even when the levels of the Reference Index are stable or increasing.

· The Underlier Is Subject to Significant Risks Associated with Futures Markets — Futures markets are subject to temporary distortions or other disruptions due to various factors, including lack of liquidity, the participation of speculators and government regulation and intervention. In addition, futures exchanges generally have regulations that limit the amount of the futures contract price fluctuations that may occur in a single day. These limits are generally referred to as “daily price fluctuation limits” and the maximum or minimum price of a contract on any given day as a result of those limits is referred to as a “limit price.” Once the limit price has been reached in a particular contract, no trades may be made at a price beyond the limit, or trading may be limited for a set period of time. Limit prices have the effect of precluding trading in a particular contract or forcing the liquidation of contracts at potentially disadvantageous times or prices. These circumstances could delay the calculation of the value of the Underlier. These factors and others can cause the prices of the futures contracts composing the Underlier to be volatile and could adversely affect the value of the Underlier and any payments on, and the value of, your Notes.

· Any Payment on the Notes May Be Postponed and Adversely Affected by the Occurrence of a Market Disruption Event — The timing and amount of any payment on the Notes is subject to adjustment upon the occurrence of a market disruption event affecting the Underlier. If a market disruption event persists for a sustained period, the Calculation Agent may make a determination of the closing value of the Underlier. See “General Terms of the Notes—Indices—Market Disruption Events,” “General Terms of the Notes—Postponement of a Determination Date” and “General Terms

Lookback Entry Enhanced Return Buffer Notes Linked to the S&P 500^® Futures Excess Return Index

· Adjustments to the Underlier or the Reference Index Could Adversely Affect Any Payments on the Notes — The sponsor of the Reference Index may add, delete, substitute or adjust the securities composing the Reference Index or the sponsor of the Underlier or the Reference Index may make methodological changes to the Underlier or the Reference Index, as applicable, that could affect its performance. The Calculation Agent will calculate the value to be used as the closing value of the Underlier in the event of certain material changes in, or modifications to, the Underlier. In addition, the sponsor of the Underlier may also discontinue or suspend calculation or publication of the Underlier at any time. Under these circumstances, the Calculation Agent may select a successor index that the Calculation Agent determines to be comparable to the Underlier or, if no successor index is available, the Calculation Agent will determine the value to be used as the closing value of the Underlier. Any of these actions could adversely affect the value of the Underlier and, consequently, the value of the Notes. See “General Terms of the Notes—Indices—Discontinuation of, or Adjustments to, an Index” in the accompanying product supplement.

UNITED STATES FEDERAL INCOME TAX CONSIDERATIONS

You should review carefully the section in the accompanying product supplement entitled “United States Federal Income Tax Considerations.” The following discussion, when read in combination with that section, constitutes the full opinion of our counsel, Davis Polk & Wardwell LLP, regarding the material U.S. federal income tax consequences of owning and disposing of the Notes.

Generally, this discussion assumes that you purchased the Notes for cash in the original issuance at the stated issue price and does not address other circumstances specific to you, including consequences that may arise due to any other investments relating to the Underlier. You should consult your tax adviser regarding the effect any such circumstances may have on the U.S. federal income tax consequences of your ownership of a Note.

In the opinion of our counsel, which is based on current market conditions, it is reasonable to treat the Notes for U.S. federal income tax purposes as prepaid financial contracts that are “open transactions,” as described in the section entitled “United States Federal Income Tax Considerations—Tax Consequences to U.S. Holders—Notes Treated as Prepaid Financial Contracts that are Open Transactions” in the accompanying product supplement. There is uncertainty regarding this treatment, and the Internal Revenue Service (the “IRS”) or a court might not agree with it. Moreover, because this treatment of the Notes and our counsel’s opinion are based on market conditions as of the date of this preliminary pricing supplement, each is subject to confirmation on the Trade Date. A different tax treatment could be adverse to you. Generally, if this treatment is respected, (i) you should not recognize taxable income or loss prior to the taxable disposition of your Notes (including upon maturity or an earlier redemption, if applicable) and (ii) the gain or loss on your Notes should be treated as short-term capital gain or loss unless you have held the Notes for more than one year, in which case your gain or loss should be treated as long-term capital gain or loss.

We do not plan to request a ruling from the IRS regarding the treatment of the Notes. An alternative characterization of the Notes could materially and adversely affect the tax consequences of ownership and disposition of the Notes, including the timing and character of income recognized. In addition, the U.S. Treasury Department and the IRS have requested comments on various issues regarding the U.S. federal income tax treatment of “prepaid forward contracts” and similar financial instruments and have indicated that such transactions may be the subject of future regulations or other guidance. Furthermore, members of Congress have proposed legislative changes to the tax treatment of derivative contracts. Any legislation, Treasury regulations or other guidance promulgated after consideration of these issues could materially and adversely affect the tax consequences of an investment in the Notes, possibly with retroactive effect.

Non-U.S. Holders. As discussed under “United States Federal Income Tax Considerations—Tax Consequences to Non-U.S. Holders—Dividend Equivalents under Section 871(m) of the Code” in the accompanying product supplement, Section 871(m) of the Internal Revenue Code and Treasury regulations promulgated thereunder (“Section 871(m)”) generally impose a 30% withholding tax on dividend equivalents paid or deemed paid to Non-U.S. Holders with respect to certain financial instruments linked to U.S. equities or indices that include U.S. equities. The Treasury regulations, as modified by an IRS notice, exempt financial instruments issued prior to January 1, 2027 that do not have a “delta” of one. Based on certain determinations made by us, we expect that Section 871(m) will not apply to the Notes with regard to Non-U.S. Holders. Our determination is not binding on the IRS, and the IRS may disagree with this determination. If necessary, further information regarding the potential application of Section 871(m) will be provided in the final pricing supplement for the Notes.

We will not be required to pay any additional amounts with respect to U.S. federal withholding taxes.

You should consult your tax adviser regarding the U.S. federal income tax consequences of an investment in the Notes, including possible alternative treatments, as well as tax consequences arising under the laws of any state, local or non-U.S. taxing jurisdiction.

SUPPLEMENTAL PLAN OF DISTRIBUTION (CONFLICTS OF INTEREST)

The Notes are offered initially to investors at a purchase price equal to par, except with respect to certain accounts as indicated on the cover page of this pricing supplement. We or one of our affiliates may pay the underwriting discount and may pay a broker-dealer that is not affiliated with us a referral fee, in each case as set forth on the cover page of this pricing supplement.

The value of the Notes shown on your account statement may be based on RBCCM’s estimate of the value of the Notes if RBCCM or another of our affiliates were to make a market in the Notes (which it is not obligated to do). That estimate will be based on the price that RBCCM may pay for the Notes in light of then-prevailing market conditions, our creditworthiness and transaction costs. For a period of approximately twelve months after the Issue Date, the value of the Notes that may be shown on your account statement may be higher than RBCCM’s estimated value of the Notes at that time. This is because the estimated value of the Notes will not include the underwriting discount, the referral fee or our hedging costs and profits; however, the value of the Notes shown on your account statement during that period may initially be a higher amount, reflecting the addition of the underwriting discount, the referral fee and our estimated costs and profits from hedging the Notes. This excess is expected to decrease over time until the end of this period. After this period, if RBCCM repurchases your Notes, it expects to do so at prices that reflect their estimated value.

RBCCM or another of its affiliates or agents may use this pricing supplement in the initial sale of the Notes. In addition, RBCCM or another of our affiliates may use this pricing supplement in a market-making transaction in the Notes after their initial sale. Unless we or our agent informs the purchaser otherwise in the confirmation of sale, this pricing supplement is being used in a market-making transaction.

For additional information about the settlement cycle of the Notes, see “Plan of Distribution” in the accompanying prospectus. For additional information as to the relationship between us and RBCCM, see the section “Plan of Distribution—Conflicts of Interest” in the accompanying prospectus.

STRUCTURING THE NOTES

The Notes are our debt securities. As is the case for all of our debt securities, including our structured notes, the economic terms of the Notes reflect our actual or perceived creditworthiness. In addition, because structured notes result in increased operational, funding and liability management costs to us, we typically borrow the funds under structured notes at a rate that is lower than the rate that we might pay for a conventional fixed or floating rate debt security of comparable maturity. The lower internal funding rate, the underwriting discount, the referral fee and the hedging-related costs relating to the Notes reduce the economic terms of the Notes to you and result in the initial estimated value for the Notes being less than their public offering price. Unlike the initial estimated value, any value of the Notes determined for purposes of a secondary market transaction may be based on a secondary market rate, which may result in a lower value for the Notes than if our initial internal funding rate were used.

In order to satisfy our payment obligations under the Notes, we may choose to enter into certain hedging arrangements (which may include call options, put options or other derivatives) with RBCCM and/or one of our other subsidiaries. The terms of these hedging arrangements take into account a number of factors, including our creditworthiness, interest rate movements, volatility and the tenor of the Notes. The economic terms of the Notes and the initial estimated value depend in part on the terms of these hedging arrangements.

See “Selected Risk Considerations—Risks Relating to the Initial Estimated Value of the Notes and the Secondary Market for the Notes—The Initial Estimated Value of the Notes Will Be Less Than the Public Offering Price” above.
