24 Appendix – Definitions Adjusted EBITDAre: Adjusted EBITDAre represents net income (loss) before interest, income taxes, depreciation and amortization, and before our share of interest and depreciation from unconsolidated real estate entities and further adjusted to eliminate the impact of certain non-cash items and items that we do not consider indicative of our ongoing performance. We believe that Adjusted EBITDAre is useful because it allows investors and management to evaluate and compare our performance from period to period in a meaningful and consistent manner, in addition to standard financial measurements under GAAP. Adjusted EBITDAre is not a measurement of financial performance under GAAP and should not be considered as an alternative to income attributable to common shareholders, as an indicator of operating performance or any measure of performance derived in accordance with GAAP. Our calculation of Adjusted EBITDAre may be different from the calculation used by other companies and, accordingly, comparability may be limited. Adjusted Funds from Operations (“AFFO”): Non-GAAP financial measure we believe is a useful supplemental measure of our performance. We compute AFFO by adding to FFO (excluding specified items) HPP’s share of non-cash compensation expense and amortization of deferred financing costs, and subtracting recurring capital expenditures related to HPP’s share of tenant improvements and leasing commissions (excluding pre-existing obligations on contributed or acquired properties funded with amounts received in settlement of prorations), and eliminating the net effect of HPP’s share of straight-line rents, amortization of lease buy-out costs, amortization of above-and below-market lease intangible assets and liabilities, amortization of above-and below-market ground lease intangible assets and liabilities and amortization of loan discounts/premiums. AFFO is not intended to represent cash flow for the period. We believe that AFFO provides useful information to the investment community about our financial position as compared to other REITs since AFFO is a widely reported measure used by other REITs. However, other REITs may use different methodologies for calculating AFFO and, accordingly, our AFFO may not be comparable to other REITs. Annualized Base Rent (“ABR”): For office properties, calculated by multiplying (i) cash base rents under commenced leases excluding tenant reimbursements as of March 31, 2023 by (ii) 12. On a per square foot basis, ABR is divided by square footage under commenced leases as of March 31, 2023. For all expiration years, ABR is calculated as (i) cash base rents at expiration under commenced leases divided by (ii) square footage under commenced leases as of March 31, 2023. The methodology is the same when calculating ABR per square foot either in place or at expiration for uncommenced leases. Rent data is presented without regard to cancellation options. Where applicable, rental rates converted to USD using the foreign currency exchange rate as of March 31, 2023. For studio properties, ABR reflects actual base rent for the 12 months ended March 31, 2023, excluding tenant reimbursements. ABR per leased square foot calculated as (i) annual base rent divided by (ii) square footage under lease as of March 31, 2023. Consolidated Debt: Consolidated unsecured and secured debt. Consolidated Debt, Net: Similar to consolidated debt, less consolidated cash and cash equivalents. Consolidated Unsecured and Secured Debt: Excludes joint venture partner debt, unamortized deferred financing costs and unamortized loan discounts/premiums related to our registered senior debt. Includes full amount of debt related to the Hill7, Hollywood Media Portfolio and 1918 Eighth joint ventures. Estimated Stabilized Yield: Calculated as the quotient of estimated NOI and our investment in a property once project stabilizes and initial rental concessions, if any, have elapsed, excluding the impact of leverage. Cash rents related to development and redevelopment projects are expected to increase over time and average cash yields are expected to be greater than estimated initial stabilized yields. Our estimates for cash yields and total costs at completion represent our current estimates, which may be updated upon project completion or sooner, if there are significant changes to expected yields or costs. We caution against placing undue reliance on the estimated stabilized yields which are based solely on our estimates, using data available to us during the development process. The amount of total investment required to reach stabilized occupancy may differ substantially from our estimates due to various factors. We can provide no assurance that the actual stabilized yields will be consistent with the estimated stabilized yields set forth herein. Estimated Project Costs: Estimated project costs exclude interest costs capitalized in accordance with ASC 835-20-50-1, personnel costs capitalized in accordance with ASC 970- 360-25 and operating expenses capitalized in accordance with ASC 970-340. Estimated Square Feet: Represents management’s estimate of leasable square footage, which may be less or more than the Building Owners and Managers Association (BOMA) rentable area. Square footage may change over time due to re-measurement or re-leasing. For land properties, square footage represents management’s estimate of developable square footage, the majority of which remains subject to entitlement approvals not yet obtained.

25 Appendix – Definitions (Cont.) Estimated Stabilization Date: Based on management’s estimate of stabilized occupancy (92.0%). Occupancy for stabilization purposes defined as the commencement of cash rental payments. Funds from Operations (“FFO”): We calculate FFO in accordance with the White Paper on FFO approved by the Board of Governors of the National Association of Real Estate Investment Trusts. The White Paper defines FFO as net income or loss calculated in accordance with GAAP, excluding gains and losses from sales of depreciable real estate and impairment write-downs associated with depreciable real estate, plus the HPP’s share of real estate-related depreciation and amortization, excluding amortization of deferred financing costs and depreciation of non-real estate assets. The calculation of FFO includes the HPP’s share of amortization of deferred revenue related to tenant-funded tenant improvements and excludes the depreciation of the related tenant improvement assets. FFO is a non-GAAP financial measure we believe is a useful supplemental measure of our operating performance. The exclusion from FFO of gains and losses from the sale of operating real estate assets allows investors and analysts to readily identify the operating results of the assets that form the core of our activity and assists in comparing those operating results between periods. Also, because FFO is generally recognized as the industry standard for reporting the operations of REITs, it facilitates comparisons of operating performance to other REITs. However, other REITs may use different methodologies to calculate FFO, and accordingly, our FFO may not be comparable to all other REITs. Implicit in historical cost accounting for real estate assets in accordance with GAAP is the assumption that the value of real estate assets diminishes predictably over time. Since real estate values have historically risen or fallen with market conditions, many industry investors and analysts have considered presentations of operating results for real estate companies using historical cost accounting alone to be insufficient. Because FFO excludes depreciation and amortization of real estate assets, we believe that FFO along with the required GAAP presentations provides a more complete measurement of our performance relative to our competitors and a more appropriate basis on which to make decisions involving operating, financing and investing activities than the required GAAP presentations alone would provide. We use FFO per share to calculate annual cash bonuses for certain employees. However, FFO should not be viewed as an alternative measure of our operating performance because it does not reflect either depreciation and amortization costs or the level of capital expenditures and leasing costs necessary to maintain the operating performance of our properties, which are significant economic costs and could materially impact our results from operations. HPP’s Share: Non-GAAP financial measures calculated as the measure on a consolidated basis, in accordance with GAAP, plus our Operating Partnership’s share of the measure from our unconsolidated joint ventures (calculated based upon the Operating Partnership’s percentage ownership interest), minus our partners’ share of the measure from our consolidated joint ventures (calculated based upon the partners’ percentage ownership interests). We believe that presenting HPP’s share of these measures provides useful information to investors regarding the Company’s financial condition and/or results of operations because we have several significant joint ventures, and in some cases, we exercise significant influence over, but do not control, the joint venture. In such instances, GAAP requires us to account for the joint venture entity using the equity method of accounting, which we do not consolidate for financial reporting purposes. In other cases, GAAP requires us to consolidate the venture even though our partner(s) own(s) a significant percentage interest. HPP’s Share of Debt: Similar to consolidated debt except it includes HPP’s share of unconsolidated joint venture debt and excludes partners’ share of consolidated joint venture partner debt. HPP’s Share of Gross Assets : HPP’s share of total assets plus HPP’s share of accumulated depreciation. HPP’s Share of Undepreciated Book Value : HPP’s share of total assets plus HPP’s share of accumulated depreciation and HPP’s share of accumulated amortization. In-Service Properties: Owned properties, excluding repositioning, redevelopment, development and held for sale properties. Net Effective Rent: Weighted average initial annual cash rent, net of annualized concessions (i.e. free rent), tenant improvements and lease commissions.

26 Appendix – Definitions (Cont.) Net Operating Income (“NOI”): We evaluate performance based upon property NOI from continuing operations. NOI is not a measure of operating results or cash flows from operating activities or cash flows as measured by GAAP and should not be considered an alternative to income from continuing operations, as an indication of our performance, or as an alternative to cash flows as a measure of liquidity, or our ability to make distributions. All companies may not calculate NOI in the same manner. We consider NOI to be a useful performance measure to investors and management because when compared across periods, NOI reflects the revenues and expenses directly associated with owning and operating our properties and the impact to operations from trends in occupancy rates, rental rates and operating costs, providing a perspective not immediately apparent from income from continuing operations. We calculate NOI as net income (loss) excluding corporate general and administrative expenses, depreciation and amortization, impairments, gains/losses on sales of real estate, interest expense, transaction-related expenses and other non-operating items. We define NOI as operating revenues (rental revenues, other property-related revenue, tenant recoveries and other operating revenues), less property-level operating expenses (external management fees, if any, and property-level general and administrative expenses). NOI on a cash basis is NOI adjusted to exclude the effect of straightline rent and other non-cash adjustments required by GAAP. We believe that NOI on a cash basis is helpful to investors as an additional measure of operating performance because it eliminates straight-line rent and other non-cash adjustments to revenue and expenses. Operating Partnership: The Company conducts all of its operations through the Operating Partnership, Hudson Pacific Properties, L.P., and serves as its sole general partner. As of March 31, 2023, the Company owned 97.2% of the ownership interest in the Operating Partnership, including unvested restricted units. Percent Occupied/Leased: For office properties, calculated as (i) square footage under commenced leases as of March 31, 2023, divided by (ii) total square feet, expressed as a percentage, whereas percent leased includes uncommenced leases. For studio properties, percent occupied reflects the average percent occupied for the 12 months ended March 31, 2023. Same-Store Studio: Same-store studio for the three months ended March 31, 2023 defined as all properties owned and included in our stabilized studio portfolio as of January 1, 2022 and still owned and included in the stabilized studio portfolio as of March 31, 2023.
