Definitions 37 Term Definition ABR (“Annualized Base Rent”) “Annualized base rent” or “ABR” means the contractual base rent before abatements and deducting base year operating expenses for gross and modified gross leases as of December 31, 2022, unless otherwise specified, multiplied by 12 months. For properties in our portfolio that had rent abatements as of December 31, 2022, we used the monthly contractual base rent payable following expiration of the abatement EBITDA Earnings before interest, tax, depreciation and amortization EBITDAre The National Association of Real Estate Investment Trusts ("NAREIT") has defined EBITDAre as follows: (a) GAAP Net Income 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. Adjustments to reflect the entity's share of EBITDAre of consolidated affiliates

Definitions (Cont’d) 38 Term Definition Investment Grade Investment grade companies means companies (e.g., a tenant or a guarantor or non-guarantor parent of a tenant) that have received an investment grade credit rating from a NRSRO approved by the U.S. Securities and Exchange Commission (e.g., Moody’s Investors Service, Inc., S&P Global Ratings and/or Fitch Ratings Inc.) or a company with a non-NRSRO credit rating (e.g., Bloomberg’s default risk rating) that management believes is generally equivalent to an NRSRO investment grade rating; management can provide no assurance as to the comparability of these ratings methodologies or that any particular rating for a company is indicative of the rating that a single NRSRO would provide in the event that it rated all companies for which the Company provides credit ratings; to the extent such companies are rated only by non-NRSRO ratings providers, such ratings providers may use methodologies that are different and less rigorous than those applied by NRSROs; moreover, because PKST provides credit ratings for some companies that are non-guarantor parents of Company's tenants, such credit ratings may not be indicative of the creditworthiness of the relevant tenants NAV Net asset value. This represents the fair value of our assets less liabilities divided by total shares and OP units outstanding Normalized EBITDAre We use Normalized EBITDAre as a non-GAAP supplemental performance measure to evaluate the operating performance of the Company. Normalized EBITDAre, as defined by the Company, represents EBITDAre (as defined by NAREIT), modified to exclude nonroutine items such as acquisition-related expenses, employee separation expenses and other non-routine costs. Normalized EBITDAre also omits the Normalized EBITDAre impact of properties sold during the period and extrapolate the operations of acquired properties to estimate a full quarter of ownership. We may also exclude the annualizing of large transaction items such as termination income recognized during the quarter. Management believes these adjustments to reconcile to Normalized EBITDAre provides investors with supplemental performance information that is consistent with the performance models and analysis used by management, and provides investors a view of the performance of our portfolio over time. Therefore, Normalized EBITDAre should not be considered as an alternative to net income, as computed in accordance with GAAP. Normalized EBITDAre may not be comparable to similarly titled measures of other companies

Definitions (Cont’d) 39 Term Definition Net Debt Total debt less cash and cash equivalents (excluding restricted cash) Net Debt (pro rata share) Total debt plus unconsolidated debt (pro rata share), less cash and cash equivalents (excluding restricted cash) Net Operating Income (NOI) & Cash NOI NOI is a non-GAAP measure which includes the revenue and expense directly attributable to our real estate properties. NOI is calculated as total revenue from real estate operations less property expenses, which includes operating property expenses, property tax expenses and management fees. Net operating income on a cash basis (“Cash NOI”) is net operating income adjusted to exclude the effect of straight-line rent and amortization of acquired above- and below-market lease intangibles adjustments required by GAAP. We believe that NOI and 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 and 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. In addition, NOI and 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 WALT Weighted average lease term (in years). This is the average remaining lease term for all leases combined, weighted based on Annualized Base Rent
