SUNSTONE HOTEL INVESTORS REPORTS RESULTS FOR THIRD QUARTER 2026

Completes Additional Accretive Common and Preferred Stock Repurchases

Further Increases Full Year Outlook

ALISO VIEJO, CA – November 6, 2026 – Sunstone Hotel Investors, Inc. (the “Company” or “Sunstone”) (NYSE: SHO) today announced results for the third quarter ended September 30, 2026.

Third Quarter 2026 Operational Results (as compared to Third Quarter 2025):

Information regarding the non-GAAP financial measures disclosed in this release is provided below in “Non-GAAP Financial Measures.” Reconciliations of non-GAAP financial measures to the most comparable GAAP measure for each of the periods presented are included later in this release.

Bryan A. Giglia, Chief Executive Officer, stated, “Our portfolio performed very well in the third quarter and generated revenue and earnings that meaningfully exceeded our expectations. Our well-located portfolio grew Total RevPAR by over 10% and Adjusted FFO per diluted share by nearly 18%, driven by broad-based strength across demand segments and from the contribution of our recent investments. Given our strong performance in the quarter and our revised expectations for near-term trends, we are once again increasing our full year outlook. While current year fundamentals have been better than expected, we are also encouraged by the trends we are seeing for next year, with robust group pace, further recovery in certain of our markets, and additional contribution from our investment activity.”

Mr. Giglia continued, “Our capital allocation activity this year demonstrates the value creation potential of our strategy. By realizing private market values through opportunistic asset sales and redeploying proceeds into the repurchase of nearly $200 million of our common and preferred stock at meaningful discounts, we have increased Adjusted FFO and NAV per share while preserving our leverage profile. Our strong balance sheet and dynamic approach to capital allocation allow us to remain nimble and deploy capital toward the opportunities we believe will offer the most compelling risk-adjusted returns, whether through investments in our portfolio, acquisitions, or the repurchase of our securities.”

Non-GAAP Financial Measures

We present the following non-GAAP financial measures that we believe are useful to investors as key supplemental measures of our operating performance: earnings before interest expense, taxes, depreciation and amortization for real estate, or EBITDAre; Adjusted EBITDAre (as defined below); funds from operations attributable to common stockholders, or FFO attributable to common stockholders; Adjusted FFO attributable to common stockholders (as defined below); hotel Adjusted EBITDAre; and hotel Adjusted EBITDAre margins. These measures should not be considered in isolation or as a substitute for measures of performance in accordance with GAAP. In addition, our calculation of these measures may not be comparable to other companies that do not define

such terms exactly the same as we do. These non-GAAP measures are used in addition to and in conjunction with results presented in accordance with GAAP. They should not be considered as alternatives to net income (loss), cash flow from operations, or any other operating performance measure prescribed by GAAP. These non-GAAP financial measures reflect additional ways of viewing our operations that we believe, when viewed with our GAAP results and the reconciliations to the corresponding GAAP financial measures, provide a more complete understanding of factors and trends affecting our business than could be obtained absent this disclosure. We strongly encourage investors to review our financial information in its entirety and not to rely on a single financial measure.

We present EBITDAre in accordance with guidelines established by the National Association of Real Estate Investment Trusts (“Nareit”), as defined in its September 2017 white paper “Earnings Before Interest, Taxes, Depreciation and Amortization for Real Estate.” We believe EBITDAre is a useful performance measure to help investors evaluate and compare the results of our operations from period to period in comparison to our peers. Nareit defines EBITDAre as net income (calculated in accordance with GAAP) plus interest expense, income tax expense, depreciation and amortization, gains or losses on the disposition of depreciated property (including gains or losses on change in control), impairment write-downs of depreciated property and of investments in unconsolidated affiliates caused by a decrease in the value of depreciated property in the affiliate, and adjustments to reflect the entity’s share of EBITDAre of unconsolidated affiliates.

We make additional adjustments to EBITDAre when evaluating our performance because we believe that the exclusion of certain additional items described below provides useful information to investors regarding our operating performance, and that the presentation of Adjusted EBITDAre, when combined with the primary GAAP presentation of net income, is beneficial to an investor’s complete understanding of our operating performance. In addition, we use both EBITDAre and Adjusted EBITDAre as measures in determining the value of hotel acquisitions and dispositions.

We believe that the presentation of FFO attributable to common stockholders provides useful information to investors regarding our operating performance because it is a measure of our operations without regard to specified noncash items such as real estate depreciation and amortization, any real estate impairment loss and any gain or loss on sale of real estate assets, all of which are based on historical cost accounting and may be of lesser significance in evaluating our current performance. Our presentation of FFO attributable to common stockholders conforms to Nareit’s definition of “FFO applicable to common shares.” Our presentation may not be comparable to FFO reported by other REITs that do not define the terms in accordance with the current Nareit definition, or that interpret the current Nareit definition differently than we do.

We also present Adjusted FFO attributable to common stockholders when evaluating our operating performance because we believe that the exclusion of certain additional items described below provides useful supplemental information to investors regarding our ongoing operating performance and may facilitate comparisons of operating performance between periods and our peer companies.

We adjust EBITDAre and FFO attributable to common stockholders for the following items, which may occur in any period, and refer to these measures as either Adjusted EBITDAre or Adjusted FFO attributable to common stockholders:

In addition, to derive Adjusted EBITDAre, we exclude the amortization of our right-of-use assets and related lease obligations as these expenses are based on historical cost accounting and do not reflect the actual rent amounts due to the respective lessors or the underlying performance of our hotels. We also exclude the effect of gains and losses on the disposition of undepreciated assets because we believe that including them in Adjusted EBITDAre is not consistent with reflecting the ongoing performance of our assets.

To derive Adjusted FFO attributable to common stockholders, we also exclude the noncash interest on our derivatives as we believe that these items are not reflective of our ongoing finance costs. Additionally, we exclude the real estate amortization of our right-of-use assets and related lease obligations (with the exception of our corporate operating lease) as these expenses are based on historical cost accounting and do not reflect the actual rent amounts due to the respective lessors or the underlying performance of our hotels. We also exclude gains or losses on the redemptions or repurchases of preferred stock, changes to deferred tax assets, liabilities or valuation allowances, and income tax benefits or provisions associated with the application of net operating loss carryforwards, uncertain tax positions or with the sale of assets.

In presenting hotel Adjusted EBITDAre and hotel Adjusted EBITDAre margins, miscellaneous non-hotel items have been excluded. We believe the calculation of hotel Adjusted EBITDAre results in a more accurate presentation of the hotel Adjusted EBITDAre margins for our hotels, and that these non-GAAP financial measures are useful to investors in evaluating our property-level operating performance.

Reconciliations of net income to EBITDAre, Adjusted EBITDAre, FFO attributable to common stockholders, Adjusted FFO attributable to common stockholders, hotel Adjusted EBITDAre and hotel Adjusted EBITDAre margins are set forth in the following pages of this release.
