Peakstone Realty Trust Reports Fourth Quarter and Full Year 2025 Results

El Segundo, Calif. (February 18, 2026) - Peakstone Realty Trust (“Peakstone” or the “Company”) (NYSE: PKST), an industrial real estate investment trust with a strategic focus on the industrial outdoor storage (“IOS”) sector, today announced its financial results for the quarter and full year ended December 31, 2025.

Proposed Merger

On February 2, 2026, the Company and PKST OP L.P., its operating partnership (the “Operating Partnership”), entered into an Agreement and Plan of Merger (the “Merger Agreement”) with certain affiliates of Brookfield Asset Management (NYSE: BAM, TSX: BAM) (“Brookfield”) in which, upon the terms and subject to the conditions set forth in the Merger Agreement, a Brookfield private real estate fund would acquire all of the outstanding shares of Peakstone for $21.00 per share in cash (collectively with the other transactions contemplated by the Merger Agreement, the “Mergers”). The all-cash transaction represents an implied enterprise value of approximately $1.2 billion. The proposed purchase price represents a premium of 34% to Peakstone’s share price on January 30, 2026, the last full trading day prior to the announcement of the Mergers, as well as a 46% premium to the Company’s 30-day volume weighted average price (VWAP) and a 51% premium to the Company’s 90-day VWAP, for the period ended January 30, 2026. The transaction was unanimously approved by the Peakstone Board of Trustees and is expected to close by the end of the second quarter of 2026, subject to customary closing conditions, including approval by the Company’s common shareholders.

Discontinued Operations

During 2025, the Company completed its strategic transformation to an industrial-only REIT through the disposition of all properties in its Office segment. As a result, the Office segment was eliminated as of December 31, 2025.

All previously disposed Office segment properties not included within the Office Discontinued Operations Properties are included within continuing operations for all periods presented.

Funds from Operations, Core Funds from Operations and Adjusted Funds from Operations

(Unaudited; in thousands except share and per share amounts)

We use Funds from Operations (“FFO”), Core Funds from Operation (“Core FFO”) and Adjusted Funds from Operations (“AFFO”) as supplemental financial measures of our performance. These measures are used by management as supplemental financial measures of operating performance. We do not use these measures as, nor should they be considered to be, alternatives to net earnings computed under GAAP, as indicators of our operating performance, as alternatives to cash from operating activities computed under GAAP or as indicators of our ability to fund our cash needs.

The summary below describes the way we use these measures, provides information regarding why we believe these measures are meaningful supplemental measures of performance and reconciles these measures from net income or loss, the most directly comparable GAAP measures.

FFO

We compute FFO in accordance with the definition adopted by the Board of Governors of the National Association of Real Estate Investment Trusts (“NAREIT”). FFO is defined as net income or loss computed in accordance with GAAP, excluding real estate related depreciation and amortization, impairment losses of depreciable real estate assets, gains (losses) from sales of depreciable real estate assets and after adjustments for unconsolidated joint ventures. FFO is used to facilitate meaningful comparisons of operating performance between periods and among other REITs, primarily because it excludes the effect of real estate depreciation and amortization and net gains (losses) from real estate sales, which are based on historical costs and implicitly assume that the value of real estate diminishes predictably over time. Since real estate values instead have historically risen or fallen with market conditions, FFO can help facilitate comparisons of operating performance between periods and among other REITs. It should be noted, however, that other REITs may not define FFO in accordance with the current NAREIT definition or may interpret the current NAREIT definition differently than we do, making comparisons less meaningful.

Core FFO

We compute Core FFO by adjusting FFO, as defined by NAREIT, to exclude certain items such as gain or loss from the extinguishment of debt, goodwill impairment, unrealized gains or losses on derivative instruments, employee separation expense, transaction expenses, lease termination fees, and other items not related to ongoing operating performance of our properties. We believe that Core FFO is a useful supplemental measure in addition to FFO because it excludes the effects of certain items which can create significant earnings volatility, but which do not directly relate to our core business operations. As with FFO, our reported Core FFO may not be comparable to Core FFO as defined by other REITs.

AFFO

AFFO is presented in addition to Core FFO. AFFO further adjusts Core FFO for certain other non-cash items, including straight-line rent adjustment, amortization of share-based compensation, deferred rent – ground lease, non-cash amortization items (e.g., amortization of above- and below-market rent, net, debt premium and discount, net, ground lease interests, tax benefits and deferred financing costs) and other non-cash transactions. We believe AFFO provides a useful supplemental measure of our operating performance and is useful in comparing our operating performance with other REITs that may not be involved in similar transactions or activities. As with Core FFO, our reported AFFO may not be comparable to AFFO as defined by other REITs.

Net Operating Income, including Cash and Same Store Cash NOI

(Unaudited; in thousands)

Net operating income (“NOI”) is a non-GAAP financial measure calculated as net income or loss, the most directly comparable financial measure calculated and presented in accordance with GAAP, excluding (to the extent applicable during the periods presented) general and administrative expenses, corporate operating expenses to related parties, impairment of real estate, depreciation and amortization, interest expense, other income, net, gains or losses on early extinguishment of debt, gains or losses on sales of real estate, impairment of goodwill, investment income or loss, transaction expense and net income or loss from discontinued operations and equity in earnings of unconsolidated real estate joint ventures. NOI on a cash basis (“Cash NOI”) is NOI adjusted to exclude the effect of straight-line rent, amortization of acquired above- and below-market lease intangibles, deferred termination income, other deferred adjustments and amortization of other intangibles. Cash NOI for our Same Store portfolio (“Same Store Cash NOI”) is Cash NOI for properties held for the entirety of all periods presented, with adjustments for lease termination fees and rent abatements (to the extent applicable during the periods presented). We believe that NOI, Cash NOI and Same-Store Cash NOI are helpful to investors as additional measures of operating performance because we believe they help both investors and management to understand the core operations of our properties excluding corporate and financing-related costs and non-cash depreciation and amortization. NOI, Cash NOI and Same Store Cash NOI are unlevered operating performance metrics of our properties and allow for a useful comparison of the operating performance of individual assets or groups of assets. These measures thereby provide an operating perspective not immediately apparent from GAAP income from operations or net income (loss). In addition, NOI, Cash NOI and Same Store Cash NOI are considered by many in the real estate industry to be useful starting points for determining the value of a real estate asset or group of assets. Because NOI, Cash NOI and Same Store Cash NOI exclude depreciation and amortization and capture neither the changes in the value of our properties that result from use or market conditions, nor the level of capital expenditures and capitalized leasing commissions necessary to maintain the operating performance of our properties, all of which have real economic effect and could materially impact our results from operations, the utility of NOI, Cash NOI and Same Store Cash NOI as measures of our performance is limited. Therefore, NOI, Cash NOI and Same Store Cash NOI should not be considered as alternatives to net income or loss, as computed in accordance with GAAP. NOI, Cash NOI and Same Store Cash NOI may not be comparable to similarly titled measures of other companies.

Our calculation of each of NOI, Cash NOI and Same Store Cash NOI is presented in the following table for the three months and full year ended December 31, 2025 and 2024 (dollars in thousands):

EBITDA, EBITDAre, and Adjusted EBITDAre

(Unaudited; in thousands)

To supplement our consolidated financial statements, which are prepared and presented in accordance with GAAP, we use EBITDA, EBITDAre and Adjusted EBITDAre , collectively, to help us evaluate our business. We use such non-GAAP financial measures to make strategic decisions, establish business plans and forecasts, identify trends affecting our business, and evaluate our operating performance. We believe that these non-GAAP financial measures, when taken collectively, may be helpful to investors because they allow for greater transparency into what measures we use in operating our business and measuring our performance and enable comparison of financial trends and results between periods where items may vary independent of business performance. These non-GAAP financial measures are presented for supplemental informational purposes only and should not be considered a substitute for financial information presented in accordance with GAAP.

We believe excluding items that neither relate to the ordinary course of business nor reflect our underlying business performance or that other companies, including companies in our industry, frequently exclude from similar non-GAAP measures enables us and our investors to compare our underlying business performance from period to period. Accordingly, we believe these adjustments facilitate a useful evaluation of our current operating performance and comparison to our past operating performance and provide investors with additional means to evaluate cost and expense trends. In addition, we also believe these adjustments enhance comparability of our financial performance and are similar measures that are widely used by analysts and investors as a means of evaluating a company’s performance.

There are a number of limitations related to our non-GAAP measures. Some of these limitations are that these measures, to the extent applicable, exclude: (i) historical or future cash requirements for maintenance capital expenditures or growth and expansion capital expenditures; (ii) depreciation and amortization, a non-cash expense, where the assets being depreciated and amortized may have to be replaced in the future and these measures do not reflect cash capital expenditure requirements for such replacements; (iii) interest expense, net, or the cash requirements necessary to service interest or principal payments on our indebtedness, which reduces cash available to us; (iv) share-based compensation expense, which has been, and will continue to be for the foreseeable future, a significant recurring expense for our business and an important part of our compensation strategy; (v) provision for income taxes, which may represent a reduction in cash available to us; and (vi) certain other items that we believe are not indicative of the performance of our portfolio. In addition, other companies, including companies in our industry, may calculate these non-GAAP measures or similarly titled non-GAAP measures differently or may use other measures to evaluate their performance, all of which could reduce the usefulness of our disclosure of non-GAAP measures as a tool for comparison.

Because of these and other limitations, these non-GAAP measures should be considered along with other financial performance measures, including our financial results prepared in accordance with GAAP.

EBITDA

EBITDA is defined as earnings before interest, tax, depreciation and amortization.

EBITDAre

EBITDAre is defined by The National Association of Real Estate Investment Trusts (“NAREIT”) as follows: (a) GAAP net income or loss, plus (b) interest expense, plus (c) income tax expense, plus (d) depreciation and amortization plus/minus (e) losses and gains on the disposition of depreciated properties, including losses/gains on change of control, plus (f) impairment write-downs of depreciated property and of investments in unconsolidated affiliates caused by a decrease in value of depreciated property in the affiliate, plus (g) adjustments to reflect the entity’s share of EBITDAre of consolidated affiliates.

Adjusted EBITDAre

Adjusted EBITDAre is defined as EBITDAre modified to exclude items such as acquisition-related expenses, employee separation expenses, share-based compensation expenses, and other items that we believe are not indicative of the performance of our portfolio. We also include an adjustment to reflect a full period of net operating income on the operating properties we acquire during the quarter and to remove net operating income on properties we dispose of during the quarter (in each case, as if such acquisition or disposition, as applicable, had occurred on the first day of the quarter). The adjustment for acquisitions is based on our estimate of the net operating income we would have received from such property if it had been owned for the full quarter; however, the net operating income we actually receive from such properties in future quarters may differ based on our experience operating such properties subsequent to closing of the acquisitions. We may also exclude the annualizing of other large transaction items such as termination income recognized during the quarter.

Our calculation of EBITDA, EBITDAre, and Adjusted EBITDAre is presented in the following table for the three months ended December 31, 2025 (dollars in thousands):

Appendix

Annualized Base Rent, Net Debt, Occupancy, and WALT Definitions

“Annualized Base Rent” or “ABR” is calculated as the monthly contractual base rent for leases that have commenced as of the end of the quarter, excluding rent abatements, multiplied by 12 months and deducting base year operating expenses for gross and modified leases, unless otherwise specified. For leases in effect at the end of any quarter that provide for rent abatement during the last month of that quarter, the Company used the monthly contractual base rent payable following expiration of the abatement period.

“Net Debt” is total debt (excluding deferred financing costs and debt premiums/discounts) less cash and cash equivalents (excluding restricted cash).

“Occupancy" is the leased square footage or usable acres, as applicable, under leases that have commenced as of the end of the quarter. "Occupancy Percentage" is total applicable Occupancy divided by the total applicable leasable square footage or usable acres.

"Operating Property" is any property not classified as a Redevelopment Property. "Operating Portfolio" refers to all Operating Properties.

"Redevelopment Property" is a property where we intend to undertake “repositioning/redevelopment work” including (i) making capital improvements to enhance its functionality, (ii) removing existing structures, (iii) building a new facility from the ground up, and/or (iv) converting the property to a different use. A Redevelopment Property will be moved to the Operating Portfolio upon the earlier of (i) achieving 90% Occupancy of the intended use or (ii) 12 months after completion of the repositioning/redevelopment work. “Redevelopment Portfolio” refers to all Redevelopment Properties.

“WALT” is the weighted average lease term in years (excluding unexercised renewal options and early termination rights) based on Annualized Base Rent.
