*Continued Progress Toward Industrial Transformation*

*Majority Industrial Portfolio – Industrial ABR Reached 60% After Quarter End*

*Significant Leverage Reduction*

*Strong Industrial Outdoor Storage ("IOS") Leasing Activity*

*$247 Million of Office Sales in 3Q and $116 Million Closed After Quarter End*

**El Segundo, Calif.

"During and subsequent to the quarter, we continued to execute on our strategy to transform Peakstone into an industrial-only REIT focused on growth in the industrial outdoor storage sector," said Michael Escalante, Peakstone's Chief Executive Officer. "We delivered strong IOS leasing results and redeployed sales proceeds toward both IOS investments and debt reduction. We ended the quarter at 5.4x net debt to Adjusted EBITDAre, with ample liquidity and a strong pipeline of IOS opportunities. We are confident in our strategy and our ability to continue executing and creating value for shareholders."

**<u>Discontinued Operations</u>**

The Company's plan to dispose of its Office segment properties represents a strategic shift in its business that met the criteria for classification as discontinued operations as of September 30, 2025. Accordingly, (i) the 16 remaining Office segment properties owned by the Company as of September 30, 2025 (all of which were classified as held for sale), and (ii) 11 Office segment properties disposed of prior to that date (collectively, the "Office Discontinued Operations Properties") were classified within discontinued operations for all periods presented. All previously disposed Office segment properties not included within the Office Discontinued Operations Properties are included within continuing operations for all periods presented.

**<u>Financial Highlights</u>**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• *Revenue:* Approximately $25.8 million from continuing operations (excludes approximately $25.2 million of revenue from Office Discontinued Operations Properties).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• *Net income*: Approximately $3.8 million; net income attributable to common shareholders of approximately $3.5 million, or $0.09 per basic and diluted share.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• *Core Funds from Operations ("Core FFO"):* $0.48 per basic and diluted share/unit.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• *Adjusted Funds from Operations ("AFFO"*): $0.47 per basic and diluted share/unit.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• *Same Store Cash Net Operating Income ("Same Store Cash NOI")*: Increased 3.7% to approximately $11.4 million compared to the same quarter last year.

At quarter end, the Company's portfolio was comprised of 86 properties reported in two segments: Industrial and Office. The Industrial segment included 70 properties, consisting of 66 operating properties and four properties designated for redevelopment or repositioning.

***Industrial Segment:***

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• During the quarter, the Company executed several IOS leases that will collectively add approximately $1.1 million of incremental IOS ABR. On a combined basis, the weighted average releasing spreads were 116% on a cash basis and 120% on a GAAP basis.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;◦ A new 2.5-year, full-site lease for all 7.5 usable acres at an IOS property in Savannah, GA that was previously under redevelopment. The lease includes 4% annual rent escalations and commenced during the quarter.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;◦ A new 8-year lease for 1.6 usable acres at an IOS property in Philadelphia, PA, estimated to commence in Q1 2026 following completion of landlord work.

The Company proactively negotiated a downsize with the existing tenant and secured a new tenant for the remaining acreage. Overall, this leasing activity resulted in releasing spreads of 239% on a cash basis and 251% on a GAAP basis. Both leases are effective October 1, 2025, and the average annual rent escalations are 3.3% on a combined basis.

**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.

Our calculation of FFO, Core FFO, and AFFO is presented in the following table for the three months ended September 30, 2025 and 2024 (dollars in thousands, except per share amounts):

**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 ended September 30, 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, stock-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.

**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.

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

Notes & Definitions 40

------

![](pkstsupplemental-9302025041.jpg)

41 Notes & Definitions ABR (Annualized Base Rent) "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. Average Annual Rent Escalations "Average Annual Rent Escalations" is defined as weighted average rental increase based on the remaining term of each lease, excluding i) unexercised renewal options and early termination rights and ii) leases that expire within one year. Cash and cash equivalents "Cash and cash equivalents" excludes restricted cash. The Company considers all short-term, highly liquid investments that are readily convertible to cash with a maturity of three months or less at the time of purchase to be cash equivalents. Cash Rent Change "Cash Rent Change" is calculated as the percentage change between initial cash rents for new/renewal leases and the expiring cash rents of comparable leases for the same space, excluding any rent abatements. We do not calculate Cash Rent Change for lease comparisons if either lease involved has any of the following characteristics, as we believe such leases do not provide a reliable basis for comparison: (i) the lease is for space that has never been leased under our ownership, (ii) the lease is for space that has been redeveloped or repositioned, (iii) the lease has a structure that is not comparable to the other lease or (iv) the lease term is less than 12 months. EBITDA, EBITDAre and Adjusted EBITDAre 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.

42 Notes & Definitions (continued) EBITDA, EBITDAre and Adjusted EBITDAre (Cont.) 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 property, 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 stock-based compensation expenses, lease terminations, debt extinguishments, transaction expenses, employee separation 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 for i) operating properties acquired during the quarter, ii) operating properties disposed of during the quarter, and iii) redevelopment properties that were re-classified to operating properties during the quarter (in each case, as if such property, as applicable, had occurred on the first day of the quarter). The adjustments for acquisitions and redevelopment properties are based on our estimate of the net operating income we would have received from such property if it had been owned or operating for the full quarter; however, the net operating income we actually receive from such properties in future quarters may differ based on our experience owning or operating such properties subsequent to the closing of the acquisition or re- classification from redevelopment.

43 Notes & Definitions (continued) Funds from Operations ("FFO"), Core Funds from Operations ("Core FFO"), and Adjusted Funds from Operations ("AFFO") 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.

44 Notes & Definitions (continued) GAAP Rent Change "GAAP Rent Change" is calculated as the percentage change between GAAP rents for new/renewal leases and the expiring GAAP rents of comparable leases for the same space. We do not calculate GAAP Rent Change for lease comparisons if either lease involved has any of the following characteristics, as we believe such leases do not provide a reliable basis for comparison: (i) the lease is for space that has never been leased under our ownership, (ii) the lease is for space that has been redeveloped or repositioned, (iii) the lease has a structure that is not comparable to the other lease or (iv) the lease term is less than 12 months. Net Debt "Net Debt" is total debt (excluding deferred financing costs and debt premiums/discounts) less cash and cash equivalents (excluding restricted cash). See below for reconciliations of total debt to net debt for 9/30/2025, 6/30/2025 and 9/30/2024. As of quarter 9/30/2025 6/30/2025 9/30/2024 Total Debt $1,050,766 $1,260,326 $1,183,018 Less: Cash and cash equivalents (excl. restricted cash) (326,085) (264,392) (241,550) Net Debt $724,681 $995,934 $941,468

45 Notes & Definitions (continued) Net Operating Income (NOI), Cash NOI, and Same Store Cash NOI 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.

46 Notes & Definitions (continued) Occupancy or Occupancy Percentage "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 Margin "Operating Margin" is NOI divided by revenue. Operating Partnership "Operating Partnership" refers to our operating partnership, PKST OP, L.P., which owns directly and indirectly all of the Company's assets. OP Units "OP Units" represent the outstanding common units of limited partnership interest in the Operating Partnership. Operating Property or Operating Portfolio "Operating Property" is any property not classified as a Redevelopment Property. "Operating Portfolio" refers to all Operating Properties. Per Share "Per Share" data represents amounts calculated based on the weighted-average number of basic and diluted common shares outstanding. Per Share/Unit "Per Share/Unit" data represents amounts calculated based on (i) the weighted-average number of basic and diluted common shares outstanding plus (ii) the weighted-average number of OP Units outstanding (that are owned by unitholders other than Peakstone Realty Trust). This metric is used in FFO and AFFO calculations. Redevelopment Property "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. Same Store "Same store" portfolio means properties which were held for a full period compared to the same period in the prior year. WALT "WALT" is the weighted average lease term in years (excluding unexercised renewal options and early termination rights) based on Annualized Base Rent.
