Pending Merger Transaction

On April 24, 2022, the Company and PS Business Parks, L.P. (the “OP”) entered into an Agreement and Plan of Merger (the “Merger Agreement”) whereby affiliates of Blackstone Real Estate. (“Blackstone”) will acquire all outstanding shares of the Company’s common stock for $187.50 per share in cash. Subject to the terms and conditions set forth in the Merger Agreement, each share of the Company’s common stock and each common unit of partnership interest of the OP, respectively, will be converted into the right to receive an amount in cash equal to $187.50, without interest. Each share of the Company’s outstanding preferred stock (and each depositary share representing an interest therein) will be unaffected and will remain outstanding in accordance with their respective terms. The merger transaction is expected to close in the third quarter of 2022. However, the merger transaction is subject to customary closing conditions, including approval by the Company’s common stockholders. The Company can provide no assurances regarding whether the merger will close when expected or at all.

Financial Results

Net income allocable to common stockholders for the three months ended March 31, 2022 was $72.0 million, or $2.60 per diluted common share.

FFO for the three months ended March 31, 2022 was $1.65 per share, representing a 1.2% decrease from the same period in 2021. The decrease in FFO per share for the first quarter was due to a one-time cash payment of $6.6 million to the former Chief Executive Officer ("CEO"), for RSUs and a $0.1 million cash payment for COBRA coverage reimbursement, in accordance with his separation agreement, partially offset by $0.6 million non-cash adjustment related to the reversal of stock compensation for the unvested former CEO's shares, net of dividend forfeiture expense. The decrease in FFO was partially offset by lower preferred distributions in the first quarter due to the Series W preferred stock redemption in Q4 2021.

Core FFO for the three months ended March 31, 2022 was $1.82 per share, representing a 9.0% increase from the same period in 2021. Core FFO excludes the impact of the one-time cost associated with the Company's payout of the above-mentioned former CEO compensation expense.

FAD for the quarter ended March 31, 2022 was $50.2 million, representing a 0.1% decrease from the same period in 2021. The decrease in FAD for the quarter ended March 31, 2022 is primarily attributable to higher recurring capital expenditures compared to the same period in the prior year, virtually offset by higher Same Park Cash NOI driven by higher weighted average occupancy combined with higher cash rent growth compared to the same period in the prior year.

Same Park NOI was $74.1 million for the three months ended March 31, 2022, representing a 7.7% increase over the same period in 2021.

The Company also reports NOI on a cash basis, which excludes non-cash rental income such as amortization of deferred rent receivable and other non-cash items. Same Park Cash NOI was $73.7 million for the quarter ended March 31, 2022, representing an 8.6% increase over the same period in 2021. The increase in Same Park Cash NOI for the three months ended March 31, 2022 was primarily driven by higher weighted average occupancy in the first quarter of 2022, which was 96.0% versus 93.3% for the same period in 2021. The Company noted that Same Park Cash Rental Income per occupied square foot increased by 4.6% during the period, from $16.10 in 2021 to $16.84 in 2022.

Definitions/Discussion of Non-GAAP Financial Measures

Cash NOI – We utilize cash NOI to evaluate the cash flow performance of our business parks. Cash NOI represents NOI adjusted to exclude non-cash items included in rental income and non-cash expenses. The non-cash rental income includes amortization of deferred rent receivable (net of write-offs), in-place lease intangible, tenant improvement reimbursements, and lease incentives. The non-cash expense is equal to stock compensation expense for employees whose compensation expense is recorded in GAAP cost of operations in the amount of $0.5 million for each of the three months ended March 31, 2022 and 2021. We believe that cash NOI assists investors in analyzing cash flow performance of our business parks.

Cash NOI Margin – Cash NOI margin is computed by dividing Cash NOI by Cash Rental Income.

Cash Rental Income –Cash rental income represents rental income, excluding non-cash rental income, specifically amortization of deferred rent receivable (net of write-offs), in-place lease intangible, tenant improvement reimbursements, and lease incentives.

Cash Rental Income per Occupied Square Feet –Computed by dividing Cash rental income for the period by weighted average occupied square feet. Cash rental income per occupied square feet for the three month period shown is annualized.

Core Funds from Operations (Core FFO) – We calculate Core FFO by adjusting FFO, as defined below, excluding the impact of (i) charges related to the redemption of preferred stock and (ii) other nonrecurring income or expense items as appropriate. Management believes that Core FFO is a useful supplemental measure as it provides a more meaningful and consistent comparison of operating performance and allows investors to more easily compare the Company’s operating results. Because certain of these adjustments have a real economic impact on our financial condition and results from operations, the utility of Core FFO as a measure of our performance is limited. Other REITs may not calculate Core FFO in a consistent manner. Accordingly, our Core FFO may not be comparable to other REITs’ Core FFO. Core FFO should be considered only as a supplement to net income computed in accordance with GAAP as a measure of our performance.

Cost of Operations under Cash NOI – Cash cost of operations represents cost of operations, excluding non-cash stock compensation expense for employees whose compensation expense is recorded in cost of operations in the amount of $0.5 million, for each of the three months ended March 31, 2022 and 2021, which can vary significantly period to period based upon the performance of the Company.

Funds Available for Distribution (FAD) – FAD is a non-GAAP measure that represents FFO adjusted to (a) deduct recurring capital improvements that maintains the condition of our real estate, tenant improvements and lease commissions and (b) remove certain non-cash rental income or expenses such as amortization of deferred rent receivable and non-cash stock compensation expense, and (c) charges related to the redemption of preferred stock. We believe our presentation of FAD assists investors and analysts in analyzing and comparing our operating and financial performance between reporting periods. FAD is not a substitute for GAAP net cash flow in evaluating our liquidity or ability to pay dividends, because they exclude investing and financing activities presented on our statements of cash flows.

Funds from Operations (FFO) – We calculate FFO in accordance with the standards established by the National Association of Real Estate Investment Trusts (“NAREIT”). FFO represents net income (loss) (computed in accordance with GAAP), excluding gains (or losses) from sales of depreciable operating property, gains (or losses) from sales of assets incidental to our business, impairment losses of depreciable operating property or assets incidental to our business, real estate related depreciation and amortization (excluding amortization of deferred financing costs and amortization of above/below-market lease intangibles) and after adjustments for unconsolidated joint ventures. Management uses FFO as a supplemental performance measure because, in excluding real estate related depreciation and amortization, gains and losses from property dispositions, other than temporary impairments of unconsolidated real estate entities, and impairment on our investment in real estate, it provides a performance measure that, when compared year over year, captures trends in occupancy rates, rental rates and operating costs. We also believe that, as a widely recognized measure of performance used by other REITs, FFO may be used by investors as a basis to compare our operating performance with that of other REITs. However, because FFO excludes depreciation and amortization and captures neither the changes in the value of our properties that result from use or market conditions nor the level of capital expenditures and leasing commissions necessary to maintain the operating performance of our properties, all of which have real economic effects and could materially impact our results from operations, the utility of FFO as a measure of our performance is limited. Other equity REITs may not calculate or interpret FFO in accordance with the NAREIT definition as we do, and, accordingly, our FFO may not be comparable to such other REITs’ FFO. FFO should not be used as a measure of our liquidity and is not indicative of funds available for our cash needs, including our ability to pay dividends. FFO should be considered only as a supplement to net income computed in accordance with GAAP as a measure of our performance. A reconciliation of net income, the nearest GAAP equivalent, to FFO is under the additional financial data section.

Net Operating Income (NOI) – We utilize NOI, a non-GAAP financial measure, to evaluate the operating performance of our business parks. We define NOI as rental income less cost of operations. We believe NOI assists investors in analyzing the performance and value of our business parks by excluding (i) corporate overhead (i.e. general and administrative expenses) because it does not relate to the results of our business parks and (ii) depreciation and amortization expense because it does not accurately reflect changes in the fair value of our business parks.

NOI Margin –NOI margin is computed by dividing NOI by rental income.

7

Revenue Per Occupied Square Foot – Computed by dividing rental income for the period by weighted average occupied for the same period. Revenue per occupied square foot for the three month period shown is annualized.

Same Park – The Company believes that evaluation of the Same Park portfolio, defined as all properties owned and operated as of March 31, 2022 that were acquired prior to January 1, 2020, provides an informative view of how the Company’s portfolio has performed over comparable periods. As of March 31, 2022, the Same Park portfolio consisted of 25.7 million square feet, or 95.3% of the Company’s 27.0 million total square feet, excluding the Company’s 95.0% interest in a 395-unit multifamily property.

(2) S&P downgraded PSB to 'BBB+' and subsequently downgraded PSB's preferred stock to 'BBB-'. S&P placed all their ratings on PSB, including our 'BBB+' issuer credit rating, on CreditWatch with negative implications. The CreditWatch placement reflects that S&P could lower their ratings upon closing of the transaction, based on the pro forma capital structure and their view of the acquirer's aggressive financial policy. S&P no longer view PSB as being moderately strategic to Public Storage. Public Storage, which holds approximately 41% common equity interest in PSB, has agreed to Blackstone's acquisition bid. S&P previously considered PSB to be moderately strategic to Public Storage and, as such, S&P believed that Public Storage would provide support to PSB under a stress scenario. As a result, S&P applied a one-notch improvement to their standalone rating on PSB. The transaction changes S&P's view, such that they no longer expect Public Storage to support PSB under a hypothetical stress scenario. As a result, S&P downgraded PSB by one notch to 'BBB+'. S&P also lowered their ratings on PSB's preferred stock by one notch to 'BBB-', two notches below its issuer credit rating, in line with S&P's criteria.

(3) Moody’s Investors Service (“Moody’s”) has placed on review for downgrade the ratings of PS Business Parks, Inc. (PSB), including its Baa2 preferred stock rating and the (P)Baa1 senior unsecured shelf rating of its main operating subsidiary, PS Business Parks, L.P. The review for downgrade follows the announcement that the REIT, which owns a portfolio primarily comprised of multi-tenant industrial and flex properties, has entered into a definitive agreement by which affiliates of Blackstone Real Estate will acquire all of PSB’s outstanding shares in a transaction valued at about $7.6 billion. The review for downgrade reflects the likelihood that PSB’s credit profile will deteriorate under Blackstone’s ownership, with the potential for meaningfully higher leverage and secured debt levels that could result in a multi-notch downgrade of the REIT’s ratings, including crossing over to non-investment grade territory, upon transaction close.

Definitions and Non-GAAP Disclosures

Provided within this supplemental information package are measures not defined in accordance with U.S. generally accepted accounting principles (“GAAP”). We believe our presentation of these non-GAAP measures assists investors and analysts in analyzing and comparing our operating and financial performance between reporting periods. These non-GAAP measures discussed below are not substitutes of other measures of financial performance presented in accordance with GAAP. In addition, other real estate investment trusts (“REITs”) may compute these measures differently, so comparisons among REITs may not be helpful.

Assets sold or held for sale – Assets sold or held for sale represents

Assets Sold in 2022:

•702,000 square foot industrial-flex business park located in Irving, Texas – Sold in March 2022

Assets Sold in 2021:

•70,000 square foot industrial-flex building located in Irving, Texas – Sold in December 2021

•53,000 square foot industrial building located in Beltsville, Maryland – Sold in December 2021

•371,000 square foot industrial-flex business park located in San Diego, California – Sold in October 2021

•22,000 square foot industrial-flex building located in Irving, Texas – Sold in September 2021

•244,000 square foot office business park located in Herndon, Virginia – Sold in July 2021

•198,000 square foot office-oriented flex business park located in Chantilly, Virginia – Sold in June 2021

Cash NOI – We utilize cash NOI to evaluate the cash flow performance of our business parks. Cash NOI represents NOI adjusted to exclude non-cash items included in rental income and non-cash expenses. The non-cash rental income includes amortization of deferred rent receivable (net of write-offs), in-place lease intangible, tenant improvement reimbursements, and lease incentives. The non-cash expense is equal to stock compensation expense for employees whose compensation expense is recorded in GAAP cost of operations in the amount of $0.5 million.for each of the three months ended March 31, 2022 and 2021. We believe that cash NOI assists investors in analyzing cash flow performance of our business parks.

Cash Rental Income – Cash rental income represents rental income, excluding non-cash rental income, specifically amortization of deferred rent receivable (net of write-offs), in-place lease intangible, tenant improvement reimbursements, and lease incentives.

Cash Rental Income per Occupied Square Feet – Computed by dividing cash rental income for the period by weighted average occupied square feet. Cash rental income per occupied square feet for the three month period shown is annualized.

Cash Rental Rate Change – Cash rental rate change percentages are computed by taking the percentage difference between outgoing rents (including estimated expense recoveries) and incoming rents (including estimated expense recoveries) for leases executed during the period. Leases executed on spaces vacant for more than the preceding twelve months have been excluded.

First Quarter 2022 Supplemental Financial Reporting Package             29

Definitions and Non-GAAP Disclosures

Core Funds from Operations (Core FFO) – We calculate Core FFO by adjusting FFO, as defined below, excluding the impact of (i) charges related to the redemption of preferred stock and (ii) other nonrecurring income or expense items as appropriate. Management believes that Core FFO is a useful supplemental measure as it provides a more meaningful and consistent comparison of operating performance and allows investors to more easily compare the Company’s operating results. Because certain of these adjustments have a real economic impact on our financial condition and results from operations, the utility of Core FFO as a measure of our performance is limited. Other REITs may not calculate Core FFO in a consistent manner. Accordingly, our Core FFO may not be comparable to other REITs’ Core FFO. Core FFO should be considered only as a supplement to net income computed in accordance with GAAP as a measure of our performance.

Cost of Operations under Cash NOI – Cash cost of operations represents cost of operations, excluding non-cash stock compensation expense for employees whose compensation expense is recorded in cost of operations in the amount of $0.5 million, for each of the three months ended March 31, 2022 and 2021, which can vary significantly period to period based upon the performance of the Company.

Earnings before Interest, Taxes, Depreciation and Amortization for Real Estate (“EBITDAre”) – EBITDAre is defined by the National Association of Real Estate Investment Trusts (“NAREIT”) and is often utilized to evaluate the performance of real estate companies. EBITDAre is calculated as GAAP net income before interest, depreciation and amortization and adjusted to exclude gains or losses from sales of depreciable real estate assets and impairment charges on real estate assets. We believe our presentation of EBITDAre assists investors and analysts in evaluating the operating performance of our business activities, including the impact of general and administrative expenses, and without the impact from gains or losses from sales of depreciable real estate assets.

Free Cash Available after Fixed Charges – Free cash available after fixed charges represents FAD less dividends and distributions.

Funds Available for Distribution (FAD) – FAD is a non-GAAP measure that represents FFO adjusted to (a) deduct recurring capital improvements that maintains the condition of our real estate, tenant improvements and lease commissions and (b) remove certain non-cash rental income or expenses such as amortization of deferred rent receivable and non-cash stock compensation expense, and (c) charges related to the redemption of preferred stock. We believe our presentation of FAD assists investors and analysts in analyzing and comparing our operating and financial performance between reporting periods. FAD is not a substitute for GAAP net cash flow in evaluating our liquidity or ability to pay dividends, because they exclude investing and financing activities presented on our statements of cash flows. The GAAP measure most directly comparable to FAD is operating cash flow from our statements of cash flows.

Funds from Operations (FFO) – We calculate FFO in accordance with the standards established by the National Association of Real Estate Investment Trusts (“NAREIT”). FFO represents net income (loss) (computed in accordance with GAAP), excluding gains (or losses) from sales of depreciable operating property, gains (or losses) from sales of assets incidental to our business, impairment losses of depreciable operating property or assets incidental to our business, real estate related depreciation and amortization (excluding amortization of deferred financing costs and amortization of above/below-market lease intangibles) and after adjustments for unconsolidated joint ventures. Management uses FFO as a supplemental performance measure because, in excluding real estate related depreciation and amortization, gains and losses from property dispositions, other than temporary impairments of unconsolidated real estate entities, and impairment on our investment in real estate, it provides a performance measure that, when compared year over year, captures trends in occupancy rates, rental rates and operating costs. We also believe that, as a widely recognized measure of performance used by other REITs, FFO may be used by investors as a basis to compare our operating performance with that of other REITs. However, because FFO excludes depreciation and amortization and captures neither the changes in the value of our properties that result from use or market conditions nor the level of capital expenditures and leasing commissions necessary to maintain the operating performance of our properties, all of which have real economic effects and could materially impact our results from operations, the utility of FFO as a measure of our performance is limited. Other equity REITs may not calculate or interpret FFO in accordance with the NAREIT definition as we do, and, accordingly, our FFO may not be comparable to such other REITs’ FFO. FFO should not be used as a measure of our liquidity and is not indicative of funds available for our cash needs, including our ability to pay dividends. FFO should be considered only as a supplement to net income computed in accordance with GAAP as a measure of our performance. A reconciliation of net income, the nearest GAAP equivalent, to FFO is under the additional financial data section.

GAAP Rent Growth – Average net effective rent growth represents the weighted average percentage change in net effective rents for leases executed during a period compared against the prior leases for the same units. Net effective rent represents average rental payments for the term of a lease on a straight-line basis, against the ending lease rates on prior leases for the same units, excluding operating expense reimbursements.

First Quarter 2022 Supplemental Financial Reporting Package             30

Definitions and Non-GAAP Disclosures

Net Operating Income (NOI) – We utilize NOI, a non-GAAP financial measure, to evaluate the operating performance of our business parks. We define NOI as rental income less cost of operations. We believe NOI assists investors in analyzing the performance and value of our business parks by excluding (i) corporate overhead (i.e. general and administrative expenses) because it does not relate to the results of our business parks and (ii) depreciation and amortization expense because it does not accurately reflect changes in the fair value of our business parks.

Non-Recurring Property Renovations – Non-recurring property renovations represents renovations that substantially enhance the value and useful life of a property, including capitalized costs associated with repositioning of acquired assets.

Non-Same Park – Non-Same Park includes assets acquired on or subsequent to January 1, 2020.

Recurring Capital Expenditures – Recurring capital expenditures are capitalized costs necessary to continue to operate the property at its current economic value. Capital improvements in excess of $2,000 with a useful life greater than 24 months are capitalized. Lease transaction costs (i.e. tenant improvements and leasing commissions) of $1,000 or more for leases with terms greater than 12 months are capitalized. All leasing costs, including first generation tenant improvements and leasing commissions, are included in recurring capital expenditures.

Retained Cash – Retained cash represents free cash available after fixed charges less non-recurring property renovations and funds used for development and redevelopment.

Same Park – The Company believes that evaluation of the Same Park portfolio, defined as all properties owned and operated as of March 31, 2022 that were acquired prior to January 1, 2020, provides an informative view of how the Company’s portfolio has performed over comparable periods. As of March 31, 2022, the Same Park portfolio consisted of 25.7 million square feet, or 95.3% of the Company’s 27.0 million total square feet, excluding the Company’s 95.0% interest in a 395-unit multifamily property.

Transaction Costs as a Percentage of Rents – Transaction costs as a percentage of rents are computed by taking the total transaction costs divided by the total rents (including estimated expense recoveries) over the term of the lease.
