PRELIMINARY PROSPECTUS SUPPLEMENT

(To Prospectus dated December 20, 2023)

$    

American Assets Trust, L.P.

 % Senior Notes due 20 

Guaranteed by

American Assets Trust, Inc.

The notes will bear interest at the rate of % per year. Interest on the notes will be payable semi-annually in arrears on    and    of each year, beginning    , 2025. The notes will mature on    , 20 , unless earlier redeemed as described in this prospectus supplement.

American Assets Trust, L.P., which we refer to as the operating partnership, may, at its option, redeem the notes in whole or in part, at any time and from time to time, at the applicable redemption price described under the section titled “Description of Notes—Redemption of the Notes at the Option of the Operating Partnership” in this prospectus supplement. The notes will be senior unsecured obligations of the operating partnership and will rank equally in right of payment with all of its other existing and future senior unsecured indebtedness and will be effectively subordinated in right of payment to, among other things, all of its existing and future mortgage indebtedness and other secured indebtedness (to the extent of the value of the collateral securing such indebtedness) and to all existing and future indebtedness and other liabilities, whether secured or unsecured, of the operating partnership’s subsidiaries. The notes will be guaranteed by American Assets Trust, Inc., which we refer to as the Company. The Company has no material assets other than its investment in the operating partnership.

The notes are a new issue of securities with no established trading market. We do not intend to apply for listing of the notes on any securities exchange or for inclusion of the notes in any quotation system.

Insurance Company of the West, or one of its affiliates, which is controlled by Ernest Rady, our Chairman and Chief Executive Officer, has indicated an interest in purchasing an aggregate of up to approximately $50.0 million in principal amount of the notes in this offering at the public offering price of the notes and on the same terms as the other purchasers in this offering. However, because indications of interest are not binding agreements or commitments to purchase, the underwriters could determine to sell more, less or none of the notes to this potential purchaser, and this potential purchaser could determine to purchase more, less or none of the notes in this offering. The underwriters will receive the same underwriting discount and commissions on these notes as they will on any other notes sold to the public in this offering.

An investment in the notes involves various risks and prospective investors should carefully consider the matters discussed under the section titled “Risk Factors” beginning on page S-11 of this prospectus supplement and the matters discussed in the documents incorporated by reference in this prospectus supplement and the accompanying prospectus before making a decision to invest in the notes.

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

We expect that the notes will be ready for delivery in book-entry form through The Depository Trust Company on or about September , 2024, which will be the     business day following the date of the pricing of the notes (such settlement being referred to as “T+ ”). See the section titled “Underwriting (Conflicts of Interest)—Settlement Cycle.”

FORWARD-LOOKING INFORMATION

This prospectus supplement and the accompanying prospectus and the documents that we incorporate by reference in each contain “forward-looking statements” within the meaning of the Private Securities Litigation Reform Act of 1995 (set forth in Section 27A of the Securities Act of 1933, as amended, or the Securities Act, and Section 21E of the Securities Exchange Act of 1934, as amended, or the Exchange Act). Also, documents we subsequently file with the SEC and incorporate by reference will contain forward-looking statements. In particular, statements relating to our liquidity and capital resources, portfolio performance and results of operations contain forward-looking statements. Furthermore, all of the statements regarding future financial performance (including anticipated funds from operations, market conditions and demographics) are forward-looking statements. We are including this cautionary statement to make applicable, and take advantage of, the safe harbor provisions of the Private Securities Litigation Reform Act of 1995 for any such forward-looking statements. We caution investors that any forward-looking statements presented in this prospectus supplement and the accompanying prospectus and the documents that we incorporate by reference in each are based on management’s beliefs and assumptions made by, and information currently available to, management.

We do not guarantee that the transactions and events described will happen as described (or that they will happen at all).

Some of the risks and uncertainties that may cause our actual results, performance, liquidity or achievements to differ materially from those expressed or implied by forward-looking statements include, among others, the following:

S-iv

While forward-looking statements reflect our good faith beliefs, they are not guarantees of future performance. We disclaim any obligation to publicly update or revise any forward-looking statement to reflect changes in underlying assumptions or factors, new information, data or methods, future events or other changes.

RISK FACTORS

Investing in the notes involves risks. You should carefully consider the following risks, the risks described in Item 1A of our Annual Report on Form 10-K for the year ended December 31, 2023, as well as the other information and data set forth in this prospectus supplement, the accompanying prospectus and the documents incorporated by reference herein and therein before making an investment decision with respect to the notes. The risks associated with our business and properties described or incorporated by reference herein, to the extent that they relate generally to the ownership and operation of real estate. The occurrence of any of the following risks could materially and adversely affect our business, prospects, financial condition, results of operations and our ability to repay the principal amount of the notes and the accrued interest, which could cause you to lose all or a part of your investment.

Risks Related to this Offering

The effective subordination of the notes may limit our ability to satisfy our obligations under the notes.

The notes will be the operating partnership’s senior unsecured obligations and will rank equally in right of payment with all of its other existing and future senior unsecured indebtedness. The notes will be effectively subordinated in right of payment to:

Similarly, the Company’s guarantee of the notes will be its senior unsecured obligation and will rank equally in right of payment with all of its other existing and future senior unsecured indebtedness and senior unsecured guarantees. The Company’s guarantee of the notes will be effectively subordinated in right of payment to:

The indenture that will govern the notes will not prohibit the operating partnership, the Company or any of their respective subsidiaries from incurring secured or unsecured indebtedness in the future and, although the indenture will contain covenants that will limit the ability of the operating partnership and its subsidiaries to incur secured and unsecured indebtedness, those covenants are subject to significant exceptions and limitations, and in any event the operating partnership and its subsidiaries may be able, without taking advantage of any such exceptions and limitations, to incur substantial amounts of additional secured and unsecured indebtedness without violating those covenants. Moreover, these covenants limiting the incurrence of indebtedness will not apply to the Company. For additional information, see the section titled “Description of Notes—Certain Covenants.”

S-11

In the event of the bankruptcy, liquidation, reorganization or other winding up of the operating partnership or the Company, assets that secure any of their respective secured indebtedness, secured guarantees and other secured obligations will be available to pay their respective obligations under the notes or the guarantee of the notes, as applicable, and their other respective unsecured indebtedness, unsecured guarantees and other unsecured obligations only after all of their respective indebtedness, guarantees and other obligations secured by those assets have been repaid in full, and we caution you that there may not be sufficient assets remaining to pay amounts due on the notes or the guarantee of the notes, as the case may be. In the event of the bankruptcy, liquidation, reorganization or other winding up of any of subsidiaries of the operating partnership or the Company, the rights of holders of indebtedness and other obligations of the operating partnership (including the notes) or the Company (including its guarantee of the notes), as the case may be, will be effectively subordinated to the prior claims of that subsidiary’s creditors and of the holders of any indebtedness or other obligations of or guaranteed by that subsidiary, except to the extent that the operating partnership or the Company, as the case may be, is itself a creditor with recognized claims against that subsidiary, in which case those claims would still be effectively subordinated to all indebtedness, guarantees and other obligations secured by mortgages or other liens on the assets of that subsidiary (to the extent of the value of those assets) and would be subordinate to all indebtedness, guarantees and other obligations of that subsidiary senior to that held by the operating partnership or the Company, as the case may be. Moreover, in the event of the bankruptcy, liquidation, reorganization or other winding up of any subsidiary of the operating partnership or the Company, the rights of holders of indebtedness and other obligations of the operating partnership (including the notes) or the Company (including its guarantee of the notes), as the case may be, will be effectively subordinated to any preferred equity interests in that subsidiary held by persons other than the operating partnership or the Company, as the case may be. In addition, in the event of the bankruptcy, liquidation, reorganization or other winding up of any entity that the operating partnership or the Company accounts for using the equity method of accounting, the rights of holders of indebtedness and other obligations of the operating partnership (including the notes) or the Company (including its guarantee of the notes), as the case may be, will be subject to the prior claims of that entity’s creditors and the holders of any indebtedness or other obligations of or guaranteed by that entity, except to the extent that the operating partnership or the Company, as the case may be, is itself a creditor with recognized claims against that entity, in which case those claims would still be effectively subordinated to all indebtedness, guarantees and other obligations secured by mortgages or other liens on the assets of that entity (to the extent of the value of those assets) and would be subordinate to all indebtedness, guarantees and other obligations of that entity senior to that held by the operating partnership or the Company, as the case may be.

As of June 30, 2024, the operating partnership (excluding its subsidiaries) had, in addition to trade payables and other liabilities, approximately $1.6 billion aggregate principal amount of outstanding unsecured indebtedness (including borrowings outstanding under its 3.375% senior unsecured notes, senior guaranteed notes, third amended and restated credit facility and amended and restated unsecured term loan facility), had no borrowing capacity available under its $100.0 million unsecured term loan under its third amended and restated credit facility, and had no borrowing capacity under its $150.0 million or $75.0 million unsecured term loans under its amended and restated unsecured term loan facility. In addition, as of June 30, 2024, the operating partnership had $400.0 million of remaining borrowing capacity available (subject to customary conditions) under the Revolver Loan under its third amended and restated credit facility, of which the Company drew $100.0 million on July 18, 2024 to repay the $100.0 million outstanding principal amount of the operating partnership’s 3.78% Senior Guaranteed Notes, Series F, due July 19, 2024, or Series F Notes, at maturity. As of June 30, 2024, the Company (excluding its subsidiaries) had no outstanding indebtedness and had guaranteed the operating partnership’s borrowings under the operating partnership’s 3.375% senior unsecured notes, senior guaranteed notes, third amended and restated credit facility and amended and restated unsecured term loan facility and other outstanding indebtedness of the operating partnership totaling approximately $1.6 billion aggregate principal amount. As of June 30, 2024, the subsidiaries of the operating partnership and the subsidiaries of the Company (excluding the operating partnership) had approximately $75.0 million aggregate principal amount of secured indebtedness outstanding and no outstanding unsecured indebtedness, in addition to their trade payables and other liabilities. In addition, as of June 30, 2024, the subsidiaries of the operating partnership and the subsidiaries of the Company did not guarantee any indebtedness of the operating partnership or the Company.

S-12

We may not be able to meet our debt service obligations.

Our ability to make payments on and to refinance our indebtedness, including the notes, and to fund our operations, working capital and capital expenditures, depends on our ability to generate cash in the future. Our cash flow is subject to general economic, industry, financial, competitive, operating, legislative, regulatory, environmental and other factors, many of which are beyond our control. Our level of debt and the limitations imposed on us by our debt agreements could have significant adverse consequences, including the following:

If any one of these events were to occur, our financial condition, results of operations, cash flow and per share trading price of our common stock could be adversely affected. Furthermore, foreclosures could create taxable income without accompanying cash proceeds, which could hinder our ability to meet the REIT distribution requirements imposed by the Internal Revenue Code of 1986, as amended, or the Code.

The instruments and agreements governing some of our outstanding indebtedness (including borrowings under the operating partnership’s third amended and restated credit facility, amended and restated unsecured term loan facility and senior guaranteed notes) contain provisions that require us to repurchase for cash or repay that indebtedness under specified circumstances or upon the occurrence of specified events (including upon the acquisition by any person or group of more than a specified percentage of the aggregate voting power of all of the Company’s issued and outstanding voting stock, if the Company ceases to be the sole general partner of the operating partnership or the Company ceases to own, directly or indirectly, a majority of the voting equity interests in the operating partnership) and our future debt agreements and debt securities may contain similar provisions or may require that we repay or repurchase or offer to repurchase for cash the applicable indebtedness under specified circumstances or upon the occurrence of specified changes of control of the Company or the operating partnership or other events. We may not have sufficient funds to pay our indebtedness when due (including upon any such required repurchase, repayment or offer to repurchase), and we may not be able to arrange for the financing necessary to make those payments or repurchases on favorable terms or at all. In addition, our ability to make required payments on our indebtedness when due (including upon any such required repurchase, repayment or offer to repurchase) may be limited by the terms of other debt instruments or agreements. Our failure to pay amounts due in respect of any of our indebtedness when due would generally constitute an event of default under the instrument governing that indebtedness, which could permit the holders of that indebtedness to require the immediate repayment of that indebtedness in full and, in the case of secured indebtedness, could allow them to sell the collateral securing that indebtedness and use the proceeds to repay that indebtedness. Moreover, any acceleration of or default in respect of any of our indebtedness could, in turn, constitute an event of default under other debt instruments or agreements, thereby resulting in the acceleration and required repayment of that other indebtedness. Any of these events could materially adversely affect our ability to make payments of principal and interest on our indebtedness, including the notes, when due and could prevent us from making those payments altogether.

We cannot assure you that our business will generate sufficient cash flow from operations or that future sources of cash will be available to us in an amount sufficient to enable us to pay amounts due on our indebtedness,

S-13

including the notes, or to fund our other liquidity needs, including cash distributions to stockholders necessary to maintain the Company’s REIT qualification. Additionally, if we incur additional indebtedness in connection with future acquisitions or for any other purpose, our debt service obligations could increase.

We may need to refinance all or a portion of our indebtedness, including the notes, on or before maturity. Our ability to refinance our indebtedness or obtain additional financing will depend on, among other things:

As a result, we may not be able to refinance our indebtedness, including the notes, on commercially reasonable terms or at all. If we do not generate sufficient cash flow from operations, and additional borrowings or refinancings or proceeds of asset sales or other sources of cash are not available to us, we may not have sufficient cash to enable us to meet all of our obligations, including payments on the notes. Accordingly, if we cannot service our indebtedness, we may have to take actions such as seeking additional equity financing, delaying capital expenditures, or entering into strategic acquisitions and alliances.

Any of these events or circumstances could have a material adverse effect on our financial condition, results of operations, cash flows, the trading price of our securities (including the notes) and our ability to satisfy our debt service obligations and to pay dividends and distributions to our security holders. In addition, foreclosures of properties that we own could create taxable income without accompanying cash proceeds, which could require us to borrow or sell assets to raise the funds necessary to pay amounts due on our indebtedness, including the notes, and to meet the REIT distribution requirements under the Code, even if such actions are not on favorable terms.

Despite our substantial indebtedness, we may still incur significantly more debt, which could exacerbate the risks related to our indebtedness, and adversely impact our ability to pay the principal of or interest on the notes.

We may be able to incur substantial additional indebtedness in the future. Although the agreements governing our secured and unsecured indebtedness limit, and the indenture governing the notes will limit, our ability to incur additional indebtedness, these restrictions are subject to a number of significant exceptions and, in addition, we will have the ability to incur additional indebtedness, which could be substantial, without violating the limitations imposed by these debt instruments. To the extent we incur additional indebtedness, we may face additional risks associated with our indebtedness, including our possible inability to pay the principal of and interest on the notes.

The Company has no significant operations, other than as the operating partnership’s general partner, and no material assets, other than its investment in the operating partnership.

The notes will be guaranteed by the Company. However, the Company has no significant operations, other than as general partner of the operating partnership, and no material assets, other than its investment in the operating partnership. Accordingly, if the operating partnership fails to make a payment on the notes when due, there can be no assurance that the Company would have funds to pay that amount pursuant to its guarantee. Furthermore, as described above under “—The effective subordination of the notes may limit our ability to satisfy our obligations under the notes,” the Company’s guarantee will be effectively subordinated in right of payment to:

S-14

Federal and state laws allow courts, under specific circumstances, to void guarantees and require holders of guaranteed debt to return payments received from guarantors.

Under the federal bankruptcy law and comparable provisions of state fraudulent transfer laws, a court could void the guarantee of the notes provided by the Company or could subordinate the guarantee to all other debts and guarantees of the Company if, among other things, the Company, at the time it incurred or entered into its guarantee of the notes, received less than reasonably equivalent value or fair consideration for the incurrence of the guarantee and any of the following is also true:

In addition, under any of the circumstances described above, any payment by the Company pursuant to its guarantee of the notes could be voided and holders of the notes could be required to return those payments to the Company or to a fund for the benefit of the creditors of the Company.

The measures 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:

Moreover, a court might also void the Company’s guarantee of the notes, without regard to the above factors, if it found that the Company entered into its guarantee with actual or deemed intent to hinder, delay, or defraud its creditors. We cannot be certain as to the standards a court would use to determine whether reasonably equivalent value or fair consideration was received by the Company for its guarantee of the notes. If a court voided such guarantee, holders of the notes would no longer have a claim against the Company under such guarantee. In addition, the court might direct holders of the notes to repay any amounts already received from the Company under its guarantee. If the court were to void the Company’s guarantee, require the return of monies paid by the Company under its guarantee or subordinate the guarantee to other obligations of the Company, we could not assure you that funds to pay the notes would be available from the operating partnership or any of our other subsidiaries or from any other source.

There is currently no trading market for the notes, and an active public trading market for the notes may not develop or, if it develops, be maintained or be liquid. The failure of an active public trading market for the notes to develop or be maintained is likely to adversely affect the market price and liquidity of the notes.

The notes are a new issue of securities with no established trading market. We do not intend to apply for listing of the notes on any securities exchange or for inclusion in any quotation system. Although the underwriters have advised us that they intend to make a market in the notes, they are not obligated to do so and may discontinue any market-making at any time without notice. Accordingly, an active public trading market may not develop for the notes and, even if one develops, may not be maintained or be liquid. If an active public trading market for the notes does not develop or is not maintained, the market price and liquidity of the notes are likely to be adversely affected and holders may not be able to sell their notes at desired times and prices or at all. If any of the notes are traded after their purchase in this offering, they may trade at a discount, which could be substantial, from their purchase price.

S-15

The liquidity of the trading market, if any, and future trading prices of the notes will depend on many factors, including, among other things, prevailing interest rates, the financial condition, results of operations, business, prospects and credit quality of the operating partnership and its subsidiaries and the Company and its subsidiaries and other comparable entities, the market for similar securities and the overall securities markets, and may be adversely affected by unfavorable changes in any of these factors, many of which are beyond our control. In addition, market volatility or events or developments in the credit markets could materially and adversely affect the market value of the notes, regardless of the operating partnership’s, the Company’s or their respective subsidiaries’ financial condition, results of operations, business, prospects or credit quality.

The market price of the notes may fluctuate significantly.

The market price of the notes may fluctuate significantly in response to many factors, including:

Many of the factors listed above are beyond our control. These factors may cause the market price of the notes to decline, regardless of our financial condition, results of operations, business or prospects. It is impossible to provide any assurance that the market price of the notes will not fall in the future, and it may be difficult for investors to resell the notes at prices they find attractive or at all.

S-16

Holders of the notes will not be entitled to require us to redeem or repurchase the notes upon the occurrence of change of control or highly levered transactions or other designated events.

The instruments and agreements governing some of our outstanding indebtedness (including borrowings under the operating partnership’s third amended and restated credit facility, amended and restated unsecured term loan facility and senior guaranteed notes) contain provisions that require us to repurchase for cash or repay that indebtedness under specified circumstances or upon the occurrence of specified events (including upon the acquisition by any person or group of more than a specified percentage of the aggregate voting power of all of the Company’s issued and outstanding voting stock, if the Company or one of its wholly-owned subsidiaries ceases to be the sole general partner of the operating partnership or the Company ceases to own, directly or indirectly, a majority of the voting equity interests in the operating partnership) and our future debt agreements and debt securities may contain similar provisions or may require that we repay or repurchase or offer to repurchase for cash the applicable indebtedness under specified circumstances or upon the occurrence of specified changes of control of the Company or the operating partnership or other events.

The notes offered hereby do not have any similar rights to require us to repurchase or repay the notes, whether upon the occurrence of a change of control or highly leveraged transaction or otherwise, even though these transactions could increase the amount of our indebtedness or otherwise adversely affect our capital structure or credit ratings, thereby adversely affecting the market value of the notes. These provisions may also allow holders of that other indebtedness to be repaid upon the occurrence of specified transactions or events, which may deplete our available cash and sources of financing and make it difficult or impossible for us to make payments on the notes when due.

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

In general, as market interest rates rise, notes bearing interest at a fixed rate generally decline in value. Consequently, if you purchase these notes and market interest rates increase, the market value of your notes may decline. We cannot predict the future level of market interest rates.

A downgrade in our credit ratings could materially adversely affect our business and financial condition and the market value of the notes.

The credit ratings assigned to the notes and other debt securities of the operating partnership could change based upon, among other things, our results of operations and financial condition. These ratings are subject to ongoing evaluation by credit rating agencies, and we cannot assure you that any rating will not be changed or withdrawn by a rating agency in the future if, in its judgment, circumstances warrant. Moreover, these credit ratings are not recommendations to buy, sell or hold the notes or any other securities. If any of the credit rating agencies that have rated the notes or other debt securities of the operating partnership downgrades or lowers its credit rating, or if any credit rating agency indicates that it has placed any such rating on a so-called “watch list” for a possible downgrading or lowering or otherwise indicates that its outlook for that rating is negative, it could have a material adverse effect on our costs and availability of capital, which could in turn have a material adverse effect on our financial condition, results of operations, cash flows and our ability to satisfy our debt service obligations (including payments on the notes) and to make dividends and distributions to our security holders and could also have the material adverse effect on the market value of the notes.

The notes are subject to early redemption.

As described under the section titled “Description of Notes—Redemption of the Notes at the Option of the Operating Partnership,” the operating partnership may, at its option, redeem the notes offered hereby in whole or in part, at any time and from time to time, at the redemption prices described under such caption. Consequently, the operating partnership may choose to redeem your notes at times when prevailing interest rates are lower than the effective interest rate on your notes. If that were to occur, you may be unable to reinvest your redemption proceeds in an investment with a return that is as high as the return you would have earned on the notes had they not been redeemed and that presents a similar level of investment risk as the notes.

S-17

USE OF PROCEEDS

We expect that the net proceeds from this offering will be approximately $     million, after deducting the underwriting discount and our estimated expenses. We intend to use the net proceeds from this offering as follows:

Pending application of the net proceeds for these purposes, we may temporarily invest such net proceeds in marketable securities.

As of June 30, 2024, we had $100.0 million in principal amount of Series B Notes outstanding and approximately $0.8 million of accrued but unpaid interest thereon. The Series B Notes mature on February 2, 2025 and interest accrues on our Series B Notes at a rate of 4.45% per annum and is payable quarterly on the last day of January, April, July and October until maturity.

As of June 30, 2024, we had $100.0 million in principal amount of Series C Notes outstanding and approximately $0.8 million of accrued but unpaid interest thereon. The Series C Notes mature on April 1, 2025 and interest accrues on our Series C Notes at a rate of 4.50% per annum and is payable quarterly on the last day of January, April, July and October until maturity.

As of June 30, 2024, there were no amounts outstanding under our Revolver Loan under our third amended and restated credit facility. However, on July 18, 2024, we drew $100.0 million on our Revolver Loan in order to repay the $100.0 million outstanding principal amount of our Series F Notes at maturity. The Revolver Loan initially matures on January 5, 2026, with two, six-month extension options. Outstanding borrowings on the Revolver Loan bear interest at floating rates equal to the applicable secured overnight financing rate, or SOFR, plus a SOFR adjustment and a spread which ranges from 1.05%-1.50% based on our consolidated leverage ratio.

Certain of the underwriters and/or their respective affiliates are lenders under our third amended and restated credit facility. As described in this prospectus supplement, we intend to use a portion of the net proceeds from this offering to repay outstanding borrowings under the Revolver Loan under our third amended and restated credit facility. To the extent that we use a portion of the net proceeds of this offering to repay borrowings under the Revolver Loan under our third amended and restated credit facility, such underwriters and/or their respective affiliates will receive their proportionate shares of any such amount. See the section titled “Underwriting (Conflicts of Interest)—Conflicts of Interest.”

DESCRIPTION OF NOTES

The notes will be issued pursuant to an indenture, dated as of January 26, 2021, among the operating partnership, as issuer, the Company, as guarantor, and U.S. Bank Trust Company, National Association, as successor in interest to U.S. Bank National Association, as trustee, or the indenture. The terms of the notes include those stated in the indenture and those made part of the indenture by reference to the Trust Indenture Act of 1939, as amended.

The notes will be a series of “debt securities” referred to in the accompanying prospectus. The following description of some of the provisions of the notes and the indenture supplements, and to the extent inconsistent supersedes and replaces, the description of some of the general provisions of the debt securities and the indenture contained in the accompanying prospectus. The following description of some of the provisions of the notes, the officers’ certificate establishing certain terms of the notes and the indenture and the description of some of the general provisions of the debt securities and the indenture contained in the accompanying prospectus are not complete and are subject to, and qualified in their entirety by reference to, the form of the notes and indenture which have been or will be filed as exhibits to the registration statement of which the accompanying prospectus is a part and which may be obtained as described under the section titled “Where You Can Find More Information” in the accompanying prospectus. We urge you to read those documents in their entirety because they, and not this description nor the description in the accompanying prospectus, define your rights as a holder of notes. You may request a copy of those documents from us as described in the section titled “Where You Can Find More Information” in the accompanying prospectus.

As used in this “Description of Notes” and in the section titled “Description of Debt Securities and Related Guarantees” in the accompanying prospectus, references to the “operating partnership,” “we,” “our” or “us” refer solely to American Assets Trust, L.P. and not to any of its subsidiaries and references to the “Company” or “guarantor” refer solely to American Assets Trust, Inc. and not to any of its subsidiaries, unless otherwise expressly stated or the context otherwise requires.

General

The notes:

The notes will constitute a single series of debt securities under the indenture and will initially be limited to an aggregate principal amount of $   . The operating partnership may, without the consent of or notice to the holders of the notes, increase the principal amount of the notes by issuing additional notes of this series from

S-19

time to time in the future. Any such additional notes will have the same terms and provisions as the notes offered hereby, except for any difference in issue date, issue price, date from which interest will begin to accrue, interest accrued prior to the issue date and first interest payment date of those additional notes. Such additional notes may have the same CUSIP number as the applicable series of notes offered hereby so long as such additional notes are fungible for U.S. federal income tax purposes with the applicable series of notes offered hereby. The notes offered hereby and any additional notes of this series that the operating partnership may issue in the future will vote and act together as a single series of debt securities under the indenture, which means that, in circumstances where the indenture provides for holders of the notes of this series to vote or take any action, the notes offered hereby and any additional notes of this series that the operating partnership may issue in the future will vote or take that action as a single series.

Except to the extent described below under “—Certain Covenants” and in the accompanying prospectus under the section titled “Description of Debt Securities and Related Guarantees—Merger, Consolidation and Sale of Assets,” the indenture governing the notes will not prohibit the operating partnership or the Company or any of the operating partnership’s or the Company’s subsidiaries from incurring additional secured or unsecured indebtedness or issuing preferred equity in the future, nor will the indenture afford holders of the notes protection in the event of (1) a recapitalization or other highly leveraged or similar transaction involving the operating partnership or the Company, (2) a change of control of the operating partnership or the Company or (3) a merger, consolidation, reorganization, restructuring or transfer or lease of all or substantially all of the operating partnership’s or the Company’s assets or similar transactions that may adversely affect the holders of the notes. The operating partnership or the Company may, in the future, enter into certain transactions, such as the sale of all or substantially all of the operating partnership’s or the Company’s assets or a merger or consolidation, that may increase the amount of the operating partnership’s or the Company’s indebtedness or substantially change the operating partnership’s or the Company’s assets, which may have a material adverse effect on the operating partnership’s ability to service its indebtedness, including the notes, or on the Company’s ability to pay amounts due under its guarantee of the notes. Furthermore, the notes and the indenture will not include any provisions that would allow holders of the notes to require the operating partnership or the Company to repurchase or redeem the notes in the event of a transaction of the nature described above. See the sections titled “Risk Factors—The effective subordination of the notes may limit our ability to satisfy our obligations under the notes” and “Risk Factors—Holders of the notes will not be entitled to require us to redeem or repurchase the notes upon the occurrence of change of control or highly levered transactions or other designated events.”

The operating partnership does not intend to apply to list the notes on any securities exchange or include them on any quotation system.

Interest

Interest on the notes will accrue at the rate of  % per year from and including September  , 2024 or the most recent interest payment date to which interest has been paid or provided for, and will be payable semi-annually in arrears on    and    of each year, beginning    , 2025. The interest so payable will be paid to each holder in whose name a note is registered at the close of business on the    or     (whether or not a business day) immediately preceding the applicable interest payment date. Interest on the notes will be computed on the basis of a 360-day year consisting of twelve 30-day months.

Company Guarantee

The Company will guarantee the operating partnership’s obligations under the notes, including the due and punctual payment of principal of and premium, if any, and interest on the notes, whether at stated maturity, upon acceleration, upon redemption or otherwise. Under the terms of the Company’s guarantee, holders of the notes will not be required to exercise their remedies against the operating partnership before they proceed directly against the Company. The Company’s obligations under the guarantee of the notes will be limited to the maximum amount that will not, after giving effect to all other contingent and fixed liabilities of the Company,

S-20

result in the guarantee constituting a fraudulent transfer or conveyance. See the section titled “Risk Factors—Federal and state laws allow courts, under specific circumstances, to void guarantees and require holders of guaranteed debt to return payments received from guarantors.”

The covenants in the indenture that will limit the ability of the operating partnership and its subsidiaries to incur indebtedness will not apply to the Company.

The Company has no significant operations, other than as the operating partnership’s general partner, and no material assets, other than its investment in the operating partnership. Accordingly, if the operating partnership fails to make a payment on the notes when due, there can be no assurance that the Company would have funds to pay that amount pursuant to its guarantee. See the section titled “Risk Factors—The Company has no significant operations, other than as the operating partnership’s general partner, and no material assets, other than its investment in the operating partnership.”

Ranking

The notes will be the operating partnership’s senior unsecured obligations and will rank equally in right of payment with all of the operating partnership’s other existing and future senior unsecured indebtedness. The notes will be effectively subordinated in right of payment to:

As of June 30, 2024, the operating partnership (excluding its subsidiaries) had, in addition to trade payables and other liabilities, approximately $1.6 billion aggregate principal amount of outstanding unsecured indebtedness (including borrowings outstanding under its 3.375% senior unsecured notes, senior guaranteed notes, third amended and restated credit facility and amended and restated unsecured term loan facility) and no borrowing capacity under its $150.0 million or $75.0 million unsecured term loans under its amended and restated unsecured term loan facility. In addition, as of June 30, 2024, the operating partnership had $400.0 million of remaining borrowing capacity available (subject to customary conditions) under the Revolver Loan under its third amended and restated credit facility, of which the Company drew approximately $100.0 million on July 18, 2024 to repay the $100.0 million outstanding principal amount of the operating partnership’s Series F Notes at maturity. As of June 30, 2024, the Company (excluding its subsidiaries) had no outstanding indebtedness and had guaranteed the operating partnership’s borrowings under the operating partnership’s 3.375% senior unsecured notes, senior guaranteed notes, third amended and restated credit facility and amended and restated unsecured term loan facility and other outstanding indebtedness of the operating partnership totaling approximately $1.6 billion aggregate principal amount. As of June 30, 2024, the subsidiaries of the operating partnership and the subsidiaries of the Company (excluding the operating partnership) had approximately $75.0 million aggregate principal amount of secured indebtedness outstanding and no outstanding unsecured indebtedness, in addition to their trade payables and other liabilities. In addition, as of June 30, 2024, the subsidiaries of the operating partnership and the subsidiaries of the Company did not guarantee any indebtedness of the operating partnership or the Company.

The indenture that will govern the notes will not prohibit the operating partnership, the Company or any of their respective subsidiaries from incurring secured or unsecured indebtedness or issuing preferred equity in the future and, although the indenture will contain covenants that will limit the ability of the operating partnership

S-21

and its subsidiaries to incur secured and unsecured indebtedness, those covenants are subject to significant exceptions, and in any event the operating partnership and its subsidiaries may be able, without taking advantage of any such exceptions, to incur substantial amounts of additional secured and unsecured indebtedness without violating those covenants.

The guarantee of the notes will be a senior unsecured obligation of the Company and will rank equally in right of payment with all other existing and future senior unsecured indebtedness and senior unsecured guarantees of the Company. The Company’s guarantee of the notes will be effectively subordinated in right of payment to:

For additional information, see the section titled “Risk Factors—The effective subordination of the notes may limit our ability to satisfy our obligations under the notes.”

Redemption of the Notes at the Option of the Operating Partnership

Prior to    , 20 (   months prior to maturity), or the Par Call Date, the operating partnership may redeem the notes at its option, in whole or in part, at any time and from time to time, at a redemption price (expressed as a percentage of principal amount and rounded to three decimal places) equal to the greater of:

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

plus, in either case, accrued and unpaid interest thereon to the redemption date.

On or after the Par Call Date, the operating partnership may redeem the notes, in whole or in part, at any time and from time to time, at a redemption price equal to 100% of the principal amount of the notes being redeemed plus accrued and unpaid interest thereon to the redemption date.

“Treasury Rate” means, with respect to any redemption date, the yield determined by the operating partnership in accordance with the following two paragraphs.

The Treasury Rate shall be determined by the operating partnership after 4:15 p.m., New York City time (or after such time as yields on U.S. government securities are posted daily by the Board of Governors of the Federal Reserve System), on the third business day preceding the date the notice of redemption is given based upon the yield or yields for the most recent day that appear after such time on such day in the most recent statistical release published by the Board of Governors of the Federal Reserve System designated as “Selected Interest Rates (Daily)—H.15” (or any successor designation or publication), or H.15, under the caption “U.S. government securities–Treasury constant maturities–Nominal” (or any successor caption or heading), or H.15 TCM. In determining the Treasury Rate, the operating partnership shall select, as applicable: (1) the yield for the Treasury

S-22

constant maturity on H.15 exactly equal to the period from the redemption date to the Par Call Date, or the Remaining Life; or (2) if there is no such Treasury constant maturity on H.15 exactly equal to the Remaining Life, the two yields—one yield corresponding to the Treasury constant maturity on H.15 immediately shorter than and one yield corresponding to the Treasury constant maturity on H.15 immediately longer than the Remaining Life—and shall interpolate to the Par Call Date on a straight-line basis (using the actual number of days) using such yields and rounding the result to three decimal places; or (3) if there is no such Treasury constant maturity on H.15 shorter than or longer than the Remaining Life, the yield for the single Treasury constant maturity on H.15 closest to the Remaining Life. For purposes of this paragraph, the applicable Treasury constant maturity or maturities on H.15 shall be deemed to have a maturity date equal to the relevant number of months or years, as applicable, of such Treasury constant maturity from the redemption date.

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

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

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.

In the case of a partial redemption, selection of the notes for redemption will be made pro rata, by lot or by such other method as the Trustee in its sole discretion deems appropriate and fair. No notes of a principal amount of $2,000 or less will be redeemed in part. If any note is to be redeemed in part only, the notice of redemption that relates to the note will state the portion of the principal amount of the note to be redeemed. A new note in a principal amount equal to the unredeemed portion of the note will be issued in the name of the holder of the note upon surrender for cancellation of the original note. For so long as the notes are held by DTC (or another depositary), the redemption of the notes shall be done in accordance with the policies and procedures of the depositary.

Unless the operating partnership defaults 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.

Certain Covenants

The following covenants will be applicable to the notes:

Aggregate Debt Test. The operating partnership will not, and will not permit any of its Subsidiaries to, incur any Debt (including without limitation Acquired Debt) if, immediately after giving effect to the incurrence of

S-23

such Debt and the application of the proceeds from such Debt on a pro forma basis, the aggregate principal amount of all outstanding Debt of the operating partnership and its Subsidiaries (determined on a consolidated basis in accordance with GAAP) is greater than 60% of the sum of the following (without duplication):

For purposes of this covenant, Debt will be deemed to be incurred by the operating partnership or any of its Subsidiaries whenever the operating partnership or such Subsidiary shall create, assume, guarantee or otherwise become liable in respect thereof.

Debt Service Test. The operating partnership will not, and will not permit any of its Subsidiaries to, incur any Debt (including without limitation Acquired Debt) if the ratio of Consolidated Income Available for Debt Service to Annual Debt Service Charge for the period consisting of the four consecutive fiscal quarters ending with the most recently ended fiscal quarter covered in the Company’s annual or quarterly report most recently furnished to holders of the notes or filed with the SEC, as the case may be, prior to the date on which such additional Debt is to be incurred shall have been less than 1.5:1 on a pro forma basis after giving effect to the incurrence of such Debt and the application of the proceeds from such Debt (determined on a consolidated basis in accordance with GAAP), and calculated on the following assumptions:

If the Debt giving rise to the need to make the calculation described in this covenant or any other Debt incurred after the first day of the relevant four-quarter period bears interest at a floating rate, then, for purposes of calculating the Annual Debt Service Charge, the interest rate on such Debt will be computed on a pro forma basis by applying the average daily rate which would have been in effect during the entire four-quarter period to the greater of the amount of such Debt outstanding at the end of such period or the average amount of such Debt outstanding during such period.

For purposes of this covenant, Debt will be deemed to be incurred by the operating partnership or any of its Subsidiaries whenever the operating partnership or such Subsidiary shall create, assume, guarantee or otherwise become liable in respect thereof.

S-24

Secured Debt Test. The operating partnership will not, and will not permit any of its Subsidiaries to, incur any Debt (including without limitation Acquired Debt) secured by any Lien on any property or assets of the operating partnership or any of its Subsidiaries, whether owned on the date that the notes are originally issued or subsequently acquired, if, immediately after giving effect to the incurrence of such Debt and the application of the proceeds from such Debt on a pro forma basis, the aggregate principal amount (determined on a consolidated basis in accordance with GAAP) of all outstanding Debt of the operating partnership and its Subsidiaries which is secured by a Lien on any property or assets of the operating partnership or any of its Subsidiaries is greater than 40% of the sum of (without duplication):

For purposes of this covenant, Debt will be deemed to be incurred by the operating partnership or any of its Subsidiaries whenever the operating partnership or such Subsidiary shall create, assume, guarantee or otherwise become liable in respect thereof.

Future Guarantors. If at any time after the issuance of the notes, including following any release of any Subsidiary that guarantees the notes pursuant to the covenant described in this paragraph (such Subsidiary, a Subsidiary Guarantor) from its guarantee under the indenture, or a Subsidiary Guarantee, a Subsidiary of the operating partnership (including any future Subsidiary) guarantees Unsecured Debt of the operating partnership (that would constitute Debt under the first bullet of the definition thereof) in an amount equal to or greater than $5.0 million, the Company will cause such Subsidiary to guarantee the notes by executing and delivering a supplemental indenture in accordance with the indenture within 10 business days; provided that if the other Unsecured Debt of the operating partnership being guaranteed by such Subsidiary that gives rise to the obligation of such Subsidiary Guarantor to guarantee the notes pursuant to the covenant described in this paragraph is Acquired Debt, the Company will cause such Subsidiary to guarantee the notes by executing and delivering a supplemental indenture in accordance with the indenture within 30 days.

Existence. Except as permitted by the covenant described in the accompanying prospectus under the section titled “Description of Debt Securities and Related Guarantees—Merger, Consolidation and Sale of Assets,” the operating partnership will do or cause to be done all things necessary to preserve and keep in full force and effect its existence, rights (charter and statutory) and franchises, and the Company will do or cause to be done all things necessary to preserve and keep in full force and effect its existence, rights (charter and statutory) and franchises. However, neither the operating partnership nor the Company will be required to preserve any right or franchise if the board of directors of the Company (or any duly authorized committee of that board of directors), as the case may be, determines that the preservation of the right or franchise is no longer desirable in the conduct of the business of the operating partnership or the Company, as the case may be.

S-25

Maintenance of Properties. The operating partnership will cause all of its properties used or useful in the conduct of its business or the business of any Subsidiary of the operating partnership to be maintained and kept in good condition, repair and working order and supplied with all necessary equipment and cause all necessary repairs, renewals, replacements, betterments and improvements to be made, all as in the judgment of the operating partnership may be necessary in order for the operating partnership to at all times properly and advantageously conduct its business carried on in connection with such properties.

Insurance. The operating partnership will, and will cause each of its Subsidiaries to, keep in force upon all of its properties and operations insurance policies carried with responsible companies in such amounts and covering all such risks as is customary in the industry in which the operating partnership and its Subsidiaries do business in accordance with prevailing market conditions and availability.

Payment of Taxes and Other Claims. Each of the operating partnership and the Company will pay or discharge or cause to be paid or discharged before it becomes delinquent:

However, neither the Company nor the operating partnership will be required to pay or discharge or cause to be paid or discharged any tax, assessment, charge or claim the amount, applicability or validity of which is being contested in good faith by appropriate proceedings.

Provision of Financial Information. The Company will:

The Company will be deemed to have filed any of the foregoing with the trustee if the Company has filed the same with the SEC using the EDGAR filing system and such filings are publicly available.

The covenants described under this caption “—Certain Covenants” shall, insofar as they relate to the notes, be subject to covenant defeasance as described in the accompanying prospectus under the section titled “Description of Debt Securities and Related Guarantees—Discharge, Defeasance and Covenant Defeasance,” provided that, notwithstanding the foregoing, the covenant of the operating partnership and the Company to do or cause to be done all things necessary to preserve and keep in full force and effect their respective existence (except as permitted by the provisions described in the accompanying prospectus under the section titled

S-26

“Description of Debt Securities and Related Guarantees—Merger, Consolidation and Sale of Assets”) and the provisions described above under “—Provision of Financial Information” shall not be subject to covenant defeasance. In addition, the operating partnership and the Company may omit in any particular instance to comply, insofar as relates to the notes, with any covenant described under this caption “—Certain Covenants” (other than the covenant described under “—Provision of Financial Information”) if the holders of at least a majority in principal amount of the outstanding notes waive such compliance.

Suspension of Future Guarantors Covenant

For so long as (i) the notes are rated at least BBB+, Baa1 or the equivalent, provided, that if such rating is equal to BBB+, Baa1 or the equivalent it must be without qualification by a negative outlook, negative watch or any other similar indication of potential downgrade, or an Applicable Rating, by at least two of S&P, Moody’s and Fitch (or, if any of S&P, Moody’s or Fitch have been replaced in accordance with the definition of “Rating Agencies,” by at least two of the then-applicable Rating Agencies) and (ii) no default has occurred and is continuing under the indenture, the operating partnership, the Company, and the Subsidiaries will not be subject to the covenant described under the section titled “—Certain Covenants—Future Guarantors”, or the Suspended Covenant.

If at any time the notes are no longer assigned an Applicable Rating by at least two of S&P, Moody’s and Fitch (or, if any of S&P, Moody’s or Fitch have been replaced in accordance with the definition of “Rating Agencies,” by at least two of the then-applicable Rating Agencies), then the Suspended Covenant will thereafter be reinstated (such date, the Reinstatement Date) and will be applicable pursuant to the terms of the indenture (including in connection with performing any calculation or assessment to determine compliance with the terms of the indenture) and, in the event that any Subsidiaries would be required to guarantee the notes at the time of such reinstatement, the Subsidiary Guarantee of such Subsidiary shall be automatically reinstated on (or, if any such Subsidiary was not a Subsidiary Guarantor of the notes at the time of the suspension, such entity shall enter into a supplemental indenture pursuant to which it shall become a Subsidiary Guarantor of the notes under the indenture within 10 business days of) such Reinstatement Date and, unless and until the notes subsequently attain an Applicable Rating from at least two of S&P, Moody’s and Fitch (or, if any of S&P, Moody’s or Fitch have been replaced in accordance with the definition of “Rating Agencies,” by at least two of the then applicable Rating Agencies) and no default shall have occurred and be continuing (in which event the Suspended Covenant and the Subsidiary Guarantees will no longer be in effect for such time that the notes maintain an Applicable Rating from two or more Rating Agencies, subject to subsequent reinstatement thereof under the circumstances described above in this paragraph). The period of time from and including the date of suspension of the Suspended Covenant to, but excluding, the Reinstatement Date or, if there is no Reinstatement Date, through and including the final maturity date of the Notes is referred to as a Suspension Period. For purposes of clarity, it is understood that there may be one or more Suspension Periods and one or more Reinstatement Dates. The operating partnership shall provide an officers’ certificate to the trustee indicating the occurrence of any Suspension Period, Suspended Covenant or Reinstatement Date. The trustee shall have no obligation to monitor the ratings of the notes, independently determine or verify if such events have occurred or notify the holders of notes of any Suspension Period, Suspended Covenant or Reinstatement Date.

Subsidiary Guarantees

The notes will not initially be guaranteed by any Subsidiaries of the operating partnership. The obligations of any Subsidiary Guarantor under such a Subsidiary Guarantee will be limited to the amount necessary to prevent such guarantee from constituting a fraudulent transfer or conveyance under applicable law. Any Subsidiary Guarantee will be a continuing guarantee and will inure to the benefit of and be enforceable by the trustee, the holders of the notes and their successors, transferees and assigns.

S-27

A Subsidiary Guarantor will be automatically and unconditionally released from its obligations under an indenture and the related guarantee:

provided, however, that in the case of the first bullet above, (x) such sale or other disposition is made to a Person other than the operating partnership or any of its Subsidiaries and (y) such sale or disposition is otherwise permitted by the indenture.

Nothing contained in the indenture or in the notes will prevent any consolidation or merger of a Subsidiary Guarantor with or into the Guarantor, the operating partnership (in which case such Subsidiary Guarantor shall no longer be a Subsidiary Guarantor) or another Subsidiary Guarantor or shall prevent any sale or conveyance of the property of a Subsidiary Guarantor as an entirety or substantially as an entirety to the Company, operating partnership or another Subsidiary Guarantor.

Trustee

U.S. Bank Trust Company, National Association will initially act as the trustee, registrar and paying agent for the notes.

If the trustee becomes one of the operating partnership’s or the Company’s creditors, it will be subject to limitations on its rights to obtain payment of claims or to realize on some property received for any such claim, as security or otherwise. The trustee is permitted to engage in other transactions with the operating partnership, the Company or their respective subsidiaries. If, however, it acquires any conflicting interest, it must eliminate that conflict or resign.

Payments on the Notes; Paying Agent and Registrar; Transfer

The operating partnership will pay the principal of and premium, if any, and interest on notes in global form registered in the name of DTC or its nominee by wire transfer of immediately available funds to DTC or its nominee, as the case may be, as the registered holder of such global notes. The operating partnership will make all payments of principal, interest and premium, if any, with respect to certificated notes (if issued) by wire transfer of immediately available funds to the accounts specified by the holders of the certificated notes or, if no such account is specified, by mailing a check to each such holder’s registered address. The operating partnership will maintain an office or agency where notes may be presented or surrendered for payment and for registration of transfer and exchange. Interest on any note that is payable, and is punctually paid or duly provided for, on any interest payment date will be paid to the person in whose name that note (or one or more predecessor notes) is registered at the close of business on the applicable record date. The operating partnership has initially designated the trustee as paying agent and registrar for the notes and its agency in Los Angeles, California as a place where notes may be presented for payment or for registration of transfer or exchange. The operating partnership may, however, change the paying agent or registrar without prior notice to the holders of the notes, and the operating partnership may act as paying agent or registrar.

If any interest payment date, stated maturity date or redemption date of a note is not a business day, the payment otherwise required to be made on such date may be made on the next business day with the same force

S-28

and effect as if made on such interest payment date, stated maturity date or redemption date, as the case may be, and no interest shall accrue on the amount so payable for the period from and after such interest payment date, stated maturity date or redemption date, as the case may be, until such next business day. All payments will be made in United States dollars.

A holder of notes may transfer or exchange notes at the office of the registrar in accordance with the indenture. Every note presented or surrendered for registration of transfer or for exchange or redemption shall (if so required by the operating partnership or the registrar) be duly endorsed, or accompanied by a written instrument of transfer in form satisfactory to the operating partnership and the registrar, duly executed by the registered holder thereof or such holder’s attorney duly authorized in writing. No service charge shall be made for any registration of transfer or exchange of notes, but the operating partnership may require payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in connection therewith, subject to limited exceptions.

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

No Personal Liability of Directors, Officers, Employees and Stockholders

No recourse under or upon any obligation, covenant or agreement contained in the indenture, the notes or any guarantee or because of any indebtedness evidenced thereby shall be had against any past, present or future stockholder, employee, officer or director, as such, of the operating partnership or the Company (either in its capacity as the operating partnership’s general partner or as guarantor of the notes), all such liability being expressly waived and released by the acceptance of the notes by the registered holders and as part of the consideration for the issue of the notes.

Notices

The indenture provides that notices to holders of the notes will be given by mail to the addresses of holders of the notes as they appear in the note register or in accordance with the applicable procedures of DTC.

UNDERWRITING (CONFLICTS OF INTEREST)

Under the terms and subject to the conditions in an underwriting agreement dated the date of this prospectus supplement, the underwriters named below, for whom Wells Fargo Securities, LLC, Mizuho Securities USA LLC and PNC Capital Markets LLC are acting as representatives, have severally and not jointly agreed to purchase, and we have agreed to sell to them, severally and not jointly, the respective principal amount of the notes set forth opposite their respective names below:

The underwriters and the representatives are collectively referred to as the “underwriters” and the “representatives,” respectively. The underwriting agreement provides that the obligations of the underwriters are subject to certain conditions precedent, and that the underwriters will purchase all notes offered hereby if any of such notes are purchased. If an underwriter defaults, the underwriting agreement provides that the purchase commitments of the non-defaulting underwriters may be increased or the underwriting agreement may be terminated. The offering of the notes by the underwriters is subject to receipt and acceptance and subject to the underwriters’ right to reject any order in whole or in part.

The underwriters propose to offer the notes directly to the public at the public offering price specified on the cover page to this prospectus supplement and may also offer the notes to certain dealers at the public offering prices less a concession not to exceed  % of the principal amount of the notes. The underwriters may allow, and these dealers may reallow, concession to certain brokers and dealers not to exceed % of the principal amount of the notes. After the initial offering of the notes, the underwriters may change the public offering price and other selling terms.

The notes are a new issue of securities with no established trading market. We do not intend to apply for listing of the notes on any securities exchange or for quotation of the notes on any automated dealer quotation system. The underwriters have advised us that they intend to make a market in the notes, but they are not obligated to do so and may discontinue any market-making 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.

We estimate our expenses for this offering, other than the underwriting discounts and commissions, to be approximately $    , and will be payable by us.

The operating partnership and the Company have agreed to indemnify the several underwriters against certain liabilities, including liabilities under the Securities Act or to contribute to payments which the underwriters may be required to make in respect thereof.

In order to facilitate the offering, the underwriters may engage in transactions that stabilize, maintain or otherwise affect the price of the notes. Specifically, the underwriters may over-allot in connection with the offering, creating short positions in the notes for their own accounts. In addition, to cover over-allotments or to stabilize the price of the notes, the underwriters may bid for, and purchase, notes in the open market. The underwriters may reclaim selling concessions allowed to an underwriter or dealer for distributing notes in the offering if the underwriters repurchase previously distributed notes in transactions to cover short positions, in stabilization transactions or otherwise. Any of these activities may stabilize or maintain the market price of the notes above independent market levels. The underwriters are not required to engage in these activities, and may end any of these activities at any time without notice.

S-33

Conflicts of Interest

Certain of the underwriters and/or their respective affiliates are lenders under our third amended and restated credit facility. As described in this prospectus supplement, we intend to use a portion of the net proceeds from this offering to repay outstanding borrowings under the Revolver Loan under our third amended and restated credit facility. To the extent that we use a portion of the net proceeds of this offering to repay borrowings under the Revolver Loan under our third amended and restated credit facility, such underwriters and/or their respective affiliates will receive their proportionate shares of any such amount.

Other Relationships

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

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

Settlement Cycle

It is expected that delivery of the notes will be made against payment therefor on or about the date specified in the last paragraph of the cover page of this prospectus supplement, which will be the   business day following the date of the pricing of the notes (such settlement being referred to as “T+ ”). Under Rule 15c6-1 under the Exchange Act, trades in the secondary market are generally 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 first business day preceding the closing date of this offering will be required, by virtue of the fact that the notes will initially settle in T+ , to specify an alternate settlement arrangement at the time of any such trade to prevent a failed settlement.

Selling Restrictions

Prohibition of Sales to EEA Retail Investors

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, or the 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, or MiFID II; (ii) a customer within the meaning of Directive (EU) 2016/97 (as amended or superseded, or the Insurance Distribution Directive, where that customer would not

S-34

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 or superseded, or the Prospectus Regulation). Consequently, no key information document required by Regulation (EU) No 1286/2014, as amended, or 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.

Prohibition of Sales to United Kingdom Retail Investors

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, or the 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, or EUWA; (ii) a customer within the meaning of the provisions of the Financial Services and Markets Act 2000, or 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. Consequently no key information document required by Regulation (EU) No 1286/2014 as it forms part of domestic law by virtue of the EUWA, or 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.

THE COMPANY

We are a full service, vertically integrated and self-administered REIT that owns, operates, acquires and develops high quality retail, office, multifamily and mixed-use properties in attractive, high-barrier-to-entry markets in Southern California, Northern California, Washington, Oregon, Texas and Hawaii. As of September 30, 2023, our portfolio was comprised of twelve office properties; twelve retail shopping centers; a mixed-use property consisting of a 369-room all-suite hotel and a retail shopping center; and six multifamily properties. Additionally, as of September 30, 2023, we owned land at three of our properties that we classified as held for development and/or construction in progress. Our core markets include San Diego, California; the San Francisco Bay Area, California; Bellevue, Washington; Portland, Oregon and Oahu, Hawaii.

The Company is a Maryland corporation formed on July 16, 2010 to acquire the entities owning various controlling and noncontrolling interests in real estate assets owned and/or managed by Ernest S. Rady or his affiliates, including the Ernest Rady Trust U/D/T March 13, 1983, or the Rady Trust, and did not have any operating activity until the consummation of our initial public offering on January 19, 2011. The Company, as the sole general partner of the operating partnership, has control of our operating partnership and owned 78.8% of our operating partnership as of September 30, 2023. Accordingly, the Company consolidates the assets, liabilities and results of operations of our operating partnership. The Company has elected to be taxed as a REIT for federal income tax purposes commencing with its taxable year ended December 31, 2011. The Company believes that it has operated in a manner that has allowed it to qualify as a REIT for federal income tax purposes commencing with such taxable year, and intends to continue operating in such a manner. The Company conducts substantially all of its business through our operating partnership, of which it serves as the sole general partner.

Our principal executive offices are located at 3420 Carmel Mountain Road, Suite 100, San Diego, California 92121, and our telephone number is (858) 350-2600.

GUARANTOR DISCLOSURES

American Assets Trust, Inc. may guarantee debt securities of the operating partnership as described in “Description of Debt Securities and Related Guarantees.” Any such guarantees by American Assets Trust, Inc. will be full, irrevocable, unconditional and absolute joint and several guarantees to the holders of each series of such outstanding guaranteed debt securities. The Company owns all of its assets and conducts all of its operations through the operating partnership and the operating partnership is consolidated into the Company’s financial statements.

The Company and the operating partnership have filed this prospectus with the Securities and Exchange Commission registering, among other securities, debt securities of the operating partnership, which will be fully and unconditionally guaranteed by the Company. Pursuant to Rule 3-10 of Regulation S-X, subsidiary issuers of obligations guaranteed by the parent are not required to provide separate financial statements, provided that the subsidiary obligor is consolidated into the parent company’s consolidated financial statements, the parent guarantee is “full and unconditional” and, subject to certain exceptions as set forth below, the alternative disclosure required by Rule 13-01 is provided, which includes narrative disclosure and summarized financial information. Accordingly, separate consolidated financial statements of the operating partnership are not expected to be presented or incorporated by reference for future periods.

Furthermore, as permitted under Rule 13-01(a)(4)(vi) of Regulation S-X, we do not expect to present or incorporate by reference summarized financial information for the operating partnership going forward because the assets, liabilities and results of operations of the operating partnership are not materially different than the corresponding amounts in American Assets Trust, Inc.’s consolidated financial statements that have been and will be incorporated by reference herein, and management believes such summarized financial information would be repetitive and would not provide incremental value to investors.

USE OF PROCEEDS

We intend to use the net proceeds from the sale of the securities as set forth in the applicable prospectus supplement. We will not receive any proceeds from the sale of common stock by the selling securityholders.

DESCRIPTION OF DEBT SECURITIES AND RELATED GUARANTEES

This section describes the general terms and provisions of our operating partnership’s debt securities. When our operating partnership offers to sell a particular series of debt securities, we will describe the specific terms of the series in a supplement to this prospectus, along with any applicable modifications of or additions to the general terms of the debt securities as described in this prospectus, including the terms of any related guarantees by the Company and the terms, if any, on which a series of debt securities may be convertible into or exchangeable for other securities. To the extent the information contained in the prospectus supplement differs from this summary description, you should rely on the information in the prospectus supplement.

The debt securities may be offered either separately, or together with, or upon the conversion or exercise of or in exchange for, other securities described in this prospectus. Debt securities may be our operating partnership’s senior, senior subordinated or subordinated obligations and may be issued in one or more series. Unless otherwise specified in the applicable prospectus supplement, the debt securities will be our operating partnership’s direct, unsecured senior obligations and will rank equally in right of payment with all of its other senior unsecured indebtedness.

Unless otherwise specified in a prospectus supplement, the debt securities will be issued under the indenture to be entered into among our operating partnership, the Company and U.S. Bank National Association, as trustee, a form of which has been filed as an exhibit to the Registration Statement of which this prospectus is a part, or the indenture. The indenture contains the full legal text of the matters described in this section. We have summarized select portions of the indenture below. The summary is not complete and is subject to and qualified in its entirety by reference to all the provisions of the indenture, including definitions of the terms used in the indenture. Whenever we refer to particular sections or defined terms of the indenture in this prospectus or in a prospectus supplement, those sections or defined terms are incorporated by reference into this prospectus or the applicable prospectus supplement, and this summary also is subject to and qualified by reference to the description of the particular terms of a particular series of debt securities described in the applicable prospectus supplement. You should read the indenture for provisions that may be important to you. Capitalized terms used in the summary and not defined herein have the meanings specified in the indenture.

As used in this “Description of Debt Securities and Related Guarantees,” references to the “operating partnership,” refer solely to American Assets Trust, L.P. and not to any of its subsidiaries and references to the “Company”, “guarantor”, “we,” “our” or “us” refer solely to American Assets Trust, Inc. and not to any of its subsidiaries, unless otherwise expressly stated or the context otherwise requires.

General

The terms of each series of debt securities will be established by or pursuant to a resolution of the Company’s board of directors and set forth or determined in the manner provided in a resolution of the Company’s board of directors, in an officer’s certificate or by a supplemental indenture. The particular terms of each series of debt securities, along with any applicable modifications of or additions to the general terms of the debt securities as described in this prospectus, will be described in a prospectus supplement relating to such series (including any pricing supplement or term sheet). A prospectus supplement, pricing supplement or term sheet may change any of the terms of the debt securities described in this prospectus.

Unless we state otherwise in the applicable prospectus supplement, we can issue an unlimited amount of our operating partnership’s debt securities under the indenture that may be in one or more series with the same or various maturities, at par, at a premium, or at a discount. We will set forth in a prospectus supplement (including any pricing supplement or term sheet) relating to any series of debt securities being offered, the aggregate principal amount and the following terms of the debt securities, if applicable:

8

9

As discussed above, we may issue debt securities of our operating partnership that provide for an amount less than their stated principal amount to be due and payable upon declaration of acceleration of their maturity pursuant to the terms of the indenture. In addition, we may denominate the purchase price of any of the debt securities in a foreign currency or currencies or a foreign currency unit or units, and the principal of and any premium and interest on any series of debt securities may be payable in a foreign currency or currencies or a foreign currency unit or units. The applicable prospectus supplement will provide you with information on the federal income tax considerations and other special considerations applicable to any such debt securities.

No Protection in the Event of a Change of Control

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

Covenants

We will set forth in the applicable prospectus supplement any restrictive covenants applicable to any issue of any series of debt securities.

Merger, Consolidation and Sale of Assets

Unless we state otherwise in the applicable prospectus supplement, our operating partnership and the Company may consolidate with, or sell, lease or convey all or substantially all of their respective assets to, or merge with or into, any other entity, provided that the following conditions are met:

10

Upon any such merger, consolidation or conveyance, the resulting, surviving or transferee person shall succeed to, and may exercise every right and power of, our operating partnership or the Company, as the case may be, under the indenture.

Events of Default

Unless we state otherwise in the applicable prospectus supplement, the indenture provides that the following events are “Events of Default” with respect to any series of debt securities:

11

A supplemental indenture or officer’s certificate establishing the terms of a particular series of debt securities may delete, modify or add to the Events of Default described above.

If an Event of Default with respect to the debt securities of a particular series occurs and is continuing (other than an Event of Default specified in the last bullet above, which shall result in an automatic acceleration), then in every case the trustee or the holders of not less than 25% in principal amount of the outstanding debt securities of such series may declare the principal amount of, and accrued and unpaid interest on, all of the debt securities of such series to be due and payable immediately by written notice thereof to our operating partnership and the Company (and to the trustee if given by the holders). However, at any time after the declaration of acceleration (or automatic acceleration) with respect to the debt securities of such series has occurred, but before a judgment or decree for payment of the money due has been obtained by the trustee, the holders of not less than a majority in principal amount of the debt securities of such series outstanding may rescind and annul the declaration and its consequences if:

The indenture also provides that the holders of not less than a majority in principal amount of the outstanding debt securities of any series may waive any past default or Event of Default with respect to the debt securities of such series and its consequences, except, among other things, a default:

The trustee will be required to give notice to the holders of the debt securities of any particular series within 90 days of a default under the indenture with respect to the debt securities of such series known to a responsible officer (as defined in the indenture) of the trustee unless the default has been cured or waived; provided, however, that the trustee may withhold notice to the holders of the debt securities of such series of any default with respect to the debt securities of such series (except a default in the payment of the principal of or premium, if any or interest on the debt securities of such series) if responsible officers of the trustee in good faith determine the withholding to be in the interest of the holders of the debt securities of such series; and provided, further, that in the case of a default with respect to the debt securities of any series of the character specified in the penultimate bullet point of the first paragraph under this caption “Events of Default,” no such notice to holders of debt securities of such series shall be given until at least 60 days after the occurrence thereof.

The indenture provides that no holder of the debt securities of a particular series may institute any action or proceedings, judicial or otherwise, with respect to the indenture or for any remedy thereunder, unless:

12

This provision will not prevent, however, any holder of the debt securities of any series from instituting suit for the enforcement of payment of the principal of or premium if any, or interest on such debt securities on or after the respective due dates thereof.

Subject to provisions in the indenture relating to its duties in case of default, the trustee will be under no obligation to exercise any of its rights or powers under the indenture at the request or direction of any holders of debt securities of any series then outstanding under the indenture, unless the holders of debt securities of such series shall have offered to the trustee security or indemnity satisfactory to the trustee. The holders of not less than a majority in principal amount of the outstanding debt securities of any series shall have the right to direct the time, method and place of conducting any proceeding for any remedy available to the trustee, or of exercising any trust or power conferred upon the trustee with respect to the debt securities of such series. However, the trustee may refuse to follow any direction which is in conflict with any law or the indenture or which may involve the trustee in personal liability or be unduly prejudicial to the holders of the debt securities of such series not joining therein.

Within 120 days after the close of each fiscal year, our operating partnership and the Company must deliver a certificate of an officer certifying to the trustee whether or not the officer has knowledge of any default under the indenture and, if so, specifying each default and the nature and status thereof.

As used in this subsection titled “—Events of Default”, the following terms have the respective meanings specified below:

“Non-Recourse Indebtedness” means indebtedness of a Subsidiary of our operating partnership (or an entity in which our operating partnership is the general partner or managing member) that is directly or indirectly secured by real estate assets or other real estate-related assets (including equity interests) of a Subsidiary of our operating partnership (or entity in which our operating partnership is the general partner or managing member) that is the borrower and is non-recourse to our operating partnership or any Subsidiary of our operating partnership (other than pursuant to a Permitted Non-Recourse Guarantee and other than with respect to the Subsidiary of our operating partnership (or entity in which our operating partnership is the general partner or managing member) that is the borrower); provided, further, that, if any such indebtedness is partially recourse to our operating partnership or any Subsidiary of our operating partnership (other than pursuant to a Permitted Non-Recourse Guarantee and other than with respect to the Subsidiary of our operating partnership (or entity in which our operating partnership is the general partner or managing member) that is the borrower) and therefore does not meet the criteria set forth above, only the portion of such indebtedness that does meet the criteria set forth above shall constitute “Non-Recourse Indebtedness.”

“Permitted Non-Recourse Guarantees” means customary completion or budget guarantees or indemnities (including by means of separate indemnification agreements and carve-out guarantees) provided under Non-Recourse Indebtedness in the ordinary course of business by our operating partnership or any Subsidiary of our operating partnership in financing transactions that are directly or indirectly secured by real estate assets or other real estate-related assets (including equity interests) of a Subsidiary of our operating partnership (or entity in which our operating partnership is the general partner or managing member), in each case that is the borrower in such financing, but is non-recourse to our operating partnership or any of our operating partnership’s other

13

Subsidiaries, except for customary completion or budget guarantees or indemnities (including by means of separate indemnification agreements or carve-out guarantees) as are consistent with customary industry practice (such as environmental indemnities and recourse triggers based on violation of transfer restrictions and other customary exceptions to nonrecourse liability).

“Significant Subsidiary” of any specified person means any Subsidiary in which such person has invested at least $50.0 million in capital.

“Subsidiary” means, with respect to our operating partnership or the Company, any person (as defined in the indenture but excluding an individual), a majority of the outstanding voting stock, partnership interests, membership interests or other equity interest, as the case may be, of which is owned or controlled, directly or indirectly, by our operating partnership or the Company, as the case may be, or by one or more other Subsidiaries of our operating partnership or the Company, as the case may be. For the purposes of this definition, “voting stock” means stock having voting power for the election of directors, trustees or managers, as the case may be, whether at all times or only so long as no senior class of stock has such voting power by reason of any contingency.

Modification, Waiver and Meetings

Unless we state otherwise in the applicable prospectus supplement, modifications and amendments of the indenture will be permitted to be made pursuant to a supplemental indenture entered into by our operating partnership, the Company and the trustee with the consent of the holders of not less than a majority in principal amount of all outstanding debt securities of each series affected by such supplemental indenture (including consent obtained in connection with a tender offer or exchange offer for the outstanding debt securities of such series); provided, however, that no modification or amendment may, without the consent of the holder of each debt security affected thereby:

Notwithstanding the foregoing, modifications and amendments of the indenture will be permitted to be made by supplemental indenture executed by our operating partnership, the Company and the trustee without the consent of any holder of the debt securities for, among other things, any of the following purposes:
