Ares Industrial Real Estate Income Trust Inc. (referred to herein as the “Company,” “we,” “our,” or “us”) is filing this Current Report on Form 8-K in order to provide an update regarding our net asset value (“NAV”), our assets and portfolio.

Most Recent Transaction Price and Net Asset Value Per Share

November 1, 2026 Transaction Price

The transaction price for each of our share classes is equal to such share class’s NAV per share as of September 30, 2026. A calculation of the NAV per share is set forth below.

September 30, 2026 NAV Per Share

Our board of directors, including a majority of our independent directors, has adopted valuation procedures, as amended from time to time, that contain a comprehensive set of methodologies to be used in connection with the calculation of our NAV. Our most recent NAV per share for each share class, which is updated as of the last calendar day of each month, is posted on our website at www.areswms.com/solutions/aireit and is also available on our toll-free, automated telephone line at (888) 310-9352. With the approval of our board of directors, including a majority of our independent directors, we have engaged Altus Group U.S. Inc., a third-party valuation firm, to serve as our independent valuation advisor (“Altus Group” or the “Independent Valuation Advisor”) with respect to helping us administer the valuation and review process for the real properties in our portfolio, providing monthly real property appraisals and valuations for certain of our debt-related assets, reviewing annual third-party real property appraisals, reviewing the internal valuations of loans (“DST Program Loans”) provided to certain investors in our program to raise capital in private placements exempt from registration pursuant to Rule 506(b) of Regulation D under the Securities Act of 1933, as amended, through the sale of beneficial interests (“DST Interests”) in specific Delaware statutory trusts holding real properties, including properties currently indirectly owned by our operating partnership (the “DST Program”), and debt-related liabilities performed by Ares Commercial Real Estate Management LLC (our “Advisor”), providing quarterly valuations of our properties subject to master lease obligations associated with the DST Program, and assisting in the development and review of our valuation procedures.

As used below, “Fund Interests” means our outstanding shares of common stock, along with the partnership units in our operating partnership (“OP Units”), which may be or were held directly or indirectly by the Advisor, affiliates of the sponsor and the Advisor, and third parties, and “Aggregate Fund NAV” means the NAV of all the Fund Interests.

The following table sets forth the components of Aggregate Fund NAV as of September 30, 2026 and August 31, 2026:

The following table sets forth the NAV per Fund Interest as of September 30, 2026 and August 31, 2026:

Under U.S. generally accepted accounting principles (“GAAP”), we record liabilities for ongoing distribution fees that we estimate we may pay in future periods for the Fund Interests. As of September 30, 2026, we estimated approximately $138 million of ongoing distribution fees were potentially payable. We do not deduct the liability for estimated future distribution fees in our calculation of NAV since we intend for our NAV to reflect our estimated value on the date that we determine our NAV. Accordingly, our estimated NAV at any given time does not include consideration of any estimated future distribution fees that may become payable after such date.

We include no discounts to our NAV for the illiquid nature of our shares, including the limitations on our stockholders’ ability to redeem shares under our share redemption program and our ability to make exceptions to, modify or suspend our share redemption program at any time. Our NAV generally does not reflect the potential impact of exit costs (e.g. selling costs and commissions related to the sale of a property) that would likely be incurred if our assets and liabilities were liquidated or sold today. While we may use market pricing concepts to value individual components of our NAV, our per share NAV is not derived from the market pricing information of open-end real estate funds listed on stock exchanges.

Our NAV is not a representation, warranty or guarantee that: (i) we would fully realize our NAV upon a sale of our assets; (ii) shares of our common stock would trade at our per share NAV on a national securities exchange; and (iii) a stockholder would be able to realize the per share NAV if such stockholder attempted to sell his or her shares to a third party.

The valuations of our real properties as of September 30, 2026, excluding certain newly acquired properties that are currently held at cost which we believe reflects the fair value of such properties, were provided by the Independent Valuation Advisor in accordance with our valuation procedures. Certain key assumptions that were used by the Independent Valuation Advisor in the discounted cash flow analysis are set forth in the following table:

A change in the exit capitalization and discount rates used would impact the calculation of the value of our real property. For example, assuming all other factors remain constant, the changes listed below would result in the following effects on the value of our real properties, excluding certain newly acquired properties that are currently held at cost which we believe reflects the fair value of such properties:

Distributions

We authorized monthly gross distributions for each class of shares of our common stock in the amount of $0.0550 per share for the month of September 2026. These distributions were paid to all stockholders of record as of the close of business on September 30, 2026, net of, as applicable, distribution fees that are payable monthly with respect to certain classes of shares of our common stock.

Update on Our Assets and Activities

As of September 30, 2026, we directly owned and managed a real estate portfolio that included 270 industrial buildings totaling approximately 54 million square feet located in 31 markets throughout the U.S. and was 90% occupied (91% leased).

As of September 30, 2026, our leverage ratio was approximately 40% (calculated as outstanding principal balance of our borrowings, including secured financings on investments in real estate debt securities and related party notes payable, less cash and cash equivalents, divided by the fair value of our real property, net investments in unconsolidated joint venture partnerships and investments in real estate debt and securities not associated with the DST Program, as determined in accordance with our valuation procedures) and the weighted-average interest rate of our consolidated borrowings was 4.43%.

For the quarter ended September 30, 2026, we raised gross proceeds of approximately $408 million, including proceeds from our distribution reinvestment plan and the sale of DST Interests (including $64 million of DST Interests financed by DST Program Loans). The aggregate dollar amount of common stock and OP Unit redemptions requested for July, August and September, which were redeemed in full on August 1, 2026, September 1, 2026 and October 1, 2026, respectively, was $76 million.

Update on Real Properties

As of September 30, 2026 our real estate portfolio included:

•268 industrial buildings totaling approximately 54 million square feet comprised our operating portfolio, which includes stabilized properties, and was 91% occupied (91% leased) with a weighted-average remaining lease term (based on square feet) of approximately 3.5 years; and

•Two industrial buildings totaling approximately 189 thousand square feet comprised our value-add portfolio, which includes buildings acquired with the intention to reposition or redevelop, or buildings recently completed which have not yet reached stabilization. We generally consider a building to be stabilized on the earlier to occur of the first anniversary of a building’s shell completion or a building achieving 90% occupancy.

Additionally, as of September 30, 2026, we owned and managed two buildings in the pre-construction phase. Unless otherwise noted, these buildings are excluded from the presentation of our portfolio data herein.

During the trailing 12 months ended September 30, 2026, we transacted approximately 9 million square feet of new and renewal leases, and rent growth on comparable leases averaged 35%, calculated using cash basis rental rates (46% when calculated using GAAP basis rental rates). As of September 30, 2026, rents across our portfolio were estimated to be 16% below market (on a weighted-average basis).

During the three months ended September 30, 2026, we acquired eight industrial buildings for an aggregate contractual purchase price of $222 million.

During the three months ended September 30, 2026, we established a joint venture in which we hold a 51% interest and which includes a seed portfolio contributed by us comprising 14 industrial buildings.

Building Types. Our industrial buildings consist primarily of warehouse distribution facilities suitable for single or multiple customers. The following table summarizes our portfolio by building type as of September 30, 2026:

Portfolio Overview and Market Diversification. As of September 30, 2026, the average effective annual rent of our total real estate portfolio (calculated by dividing total annualized base rent, which includes the impact of any contractual tenant concessions (cash basis), by total occupied square footage) was approximately $8.30 per square foot. The following table summarizes certain operating metrics of our portfolio by market as of September 30, 2026:

We generally consider a building to be stabilized on the earlier to occur of the first anniversary of a building’s shell completion or a building achieving 90% occupancy.

Lease Terms. Lease terms typically range from one to 10 years and often include renewal options. Leases that are structured on a “triple net basis,” in which customers pay their proportionate share of real estate taxes, insurance, common area maintenance, and certain other operating costs, account for 99% of our total leased portfolio, based on number of leases. In addition, most of our leases include fixed rental increases or Consumer Price Index-based rental increases.

Lease Expirations. As of September 30, 2026, the weighted-average remaining lease term (based on square feet) of our total occupied portfolio was approximately 3.4 years, excluding renewal options. The following table summarizes the lease expirations of our occupied portfolio for leases in place as of September 30, 2026, without giving effect to the exercise of renewal options or termination rights, if any:

These statements are not guarantees of future performance, and involve certain risks, uncertainties and assumptions that are difficult to predict. The forward-looking statements included herein are based upon our current expectations, plans, estimates, assumptions, and beliefs that involve numerous risks and uncertainties.
