City Office REIT Reports Fourth Quarter and Full Year 2022 Results

VANCOUVER— February 23, 2023—City Office REIT, Inc. (NYSE: CIO) (the “Company,” “City Office,” “we” or “our”) today announced its results for the quarter and full year ended December 31, 2022.

Fourth Quarter Highlights

• Rental and other revenues were $44.6 million. GAAP net loss attributable to common stockholders was approximately $14.3 million, or ($0.36) per fully diluted share;

• Core FFO was approximately $15.4 million, or $0.38 per fully diluted share;

• AFFO was approximately $5.0 million, or $0.12 per fully diluted share;

• In-place occupancy was 86.2% as of quarter end;

• Executed approximately 108,000 square feet of new and renewal leases during the quarter;

• Declared a fourth quarter dividend of $0.20 per share of common stock, paid on January 24, 2023; and

• Declared a fourth quarter dividend of $0.4140625 per share of Series A Preferred Stock, paid on January 24, 2023.

Highlights Subsequent to Quarter End

• Increased the total authorized borrowings under the Company’s unsecured credit facility (the “Unsecured Credit Facility”) from $350 million to $375 million by entering into a three-year $25 million term loan. The variable interest rate on the term loan was effectively fixed at 5.9% by entering into an interest rate swap; and

• Entered into an interest rate swap effectively fixing the variable interest rate on $140 million of the Unsecured Credit Facility at 5.6%. These two interest rate swap transactions effectively fixed over 90% of the Company’s total debt.

“Our active approach to asset management and value creation led to strong operating results in the fourth quarter and 2022 as a whole,” commented James Farrar, the Company’s Chief Executive Officer. “For the year, we generated the highest annual Core FFO per share in the Company’s history and, in doing so, increased Core FFO per share 15% over the prior year. This was a result of, among other initiatives, our integration and stabilization of the three major acquisitions in Raleigh, Phoenix and Dallas that we made in December 2021.”

“2022 also posed significant challenges, with rapidly rising interest rates, challenging conditions in the capital markets and headwinds across the office industry. Our 2023 strategic plan focuses on enhancing occupancy, driving operating performance, repositioning select assets and pruning non-core properties, which we believe will position us for long term growth and value creation. Our goal is to enhance the composition of our portfolio while positioning ourselves with capital that can be invested to drive performance. Overall, our high-quality Sun Belt market footprint continues to underpin our confidence in our ability to outperform.”

A reconciliation of certain non-GAAP financial measures, including FFO, Core FFO, AFFO, NOI, Same Store NOI, Same Store Cash NOI, Adjusted Cash NOI and their equivalent per share measures, to the most directly comparable financial measure under U.S. generally accepted accounting principles (“GAAP”) can be found at the end of this release.

Portfolio Operations

The Company reported that its total portfolio as of December 31, 2022 contained 6.0 million net rentable square feet and was 86.2% occupied.

Net Operating Income was approximately $27.6 million and Adjusted Cash NOI (CIO share) was approximately $26.2 million for the fourth quarter of 2022.

Same Store Cash NOI decreased 1.2% for the three months ended December 31, 2022 as compared to the same period in the prior year. Same Store Cash NOI decreased 4.4% for the twelve months ended December 31, 2022 as compared to the prior year.

Leasing Activity

The Company’s total leasing activity during the fourth quarter of 2022 was approximately 108,000 square feet, which included 68,000 square feet of new leasing and 40,000 square feet of renewals. Approximately 97,000 square feet of leases signed within the quarter will commence subsequent to quarter end. The Company’s total leasing activity during the full year 2022 was approximately 777,000 square feet.

New Leasing – New leases were signed with a weighted average lease term of 5.9 years at a weighted average annual rent of $33.16 per square foot and at a weighted average cost of $7.79 per square foot per year.

Renewal Leasing – Renewal leases were signed with a weighted average lease term of 3.8 years at a weighted average annual rent of $32.58 per square foot and at a weighted average cost of $2.46 per square foot per year.

Capital Structure

As of December 31, 2022, the Company had total principal outstanding debt of approximately $693.8 million. Approximately 71.1% of the Company’s debt was fixed rate or effectively fixed rate due to an interest rate swap. City Office’s total principal outstanding debt had a weighted average maturity of approximately 3.2 years and a weighted average interest rate of 4.4%.

Subsequent to quarter end, the Company entered into an amendment to the Unsecured Credit Facility and entered into a three-year $25 million term loan. The term loan increased the Company’s total authorized borrowings under the Unsecured Credit Facility from $350 million to $375 million. In conjunction with the $25 million term loan, the Company also entered into a three-year interest rate swap for a notional amount of $25 million, effectively fixing the rate of the term loan at approximately 5.9% for the three-year term.

2

Subsequent to quarter end, the Company entered into an interest rate swap effectively fixing the variable interest rate on $140 million of the Unsecured Credit Facility at approximately 5.6% through November 16, 2025. These two interest rate swap transactions effectively fixed over 90% of the Company’s total debt.

Impairment of Real Estate

During the quarter, the Company recorded an impairment of real estate for $13.4 million. The non-cash impairment was related to the write down of the book value of 190 Office Center in Dallas, Texas and Cascade Station in Portland, Oregon for $6.9 million and $6.5 million, respectively, to the fair value for each property.

Dividends

On December 15, 2022, the Company’s Board of Directors approved and the Company declared a cash dividend of $0.20 per share of the Company’s common stock for the three months ended December 31, 2022. The dividend was paid on January 24, 2023 to common stockholders and unitholders of record as of January 10, 2023.

On December 15, 2022, the Company’s Board of Directors approved and the Company declared a cash dividend of $0.4140625 per share of the Company’s 6.625% Series A Preferred Stock for the three months ended December 31, 2022. The dividend was paid on January 24, 2023 to preferred stockholders of record as of January 10, 2023.

2023 Outlook

The Company is introducing its full year 2023 guidance. 2023 guidance assumes no share issuances and no share repurchase activity. Further, guidance does include the impact of a modest amount of speculative leasing, generally weighted towards the second half of the year.

Full Year 2023 Guidance	Low			High
Acquisitions	$	0.0M		$	0.0M
Dispositions	$	25.0M		$	75.0M
Net Operating Income	$	109.0M		$	111.0M
General & Administrative Expenses	$	14.5M		$	15.5M
Interest Expense	$	32.0M		$	33.0M
2023 Core FFO per diluted share	$	1.38		$	1.43
Net Recurring Straight-Line Rent Adjustment	$	4.5M		$	5.5M
Same Store Cash NOI Change		2.0	%		4.0	%
December 31, 2023 Occupancy		85.0	%		87.0	%

3

Material Considerations:

1. The General and Administrative Expenses guidance includes approximately $4.2 million for stock-based compensation. Our Core FFO definition excludes stock-based compensation. Excluding stock-based compensation, General and Administrative Expenses guidance for Full Year 2023 would have been $10.3 million – $11.3 million.

2. Annual weighted average fully diluted shares of common stock outstanding are assumed to be approximately 40.8 million.

The Company’s guidance is based on current plans and assumptions and subject to the risks and uncertainties more fully described in the Company’s filings with the United States Securities and Exchange Commission. This outlook reflects management’s view of current and future market conditions, including assumptions such as timing and magnitude of future acquisitions and dispositions, if any, rental rates, occupancy levels, leasing activity, our ability to renew expiring leases, uncollectible rents, operating and general administrative expenses, weighted average diluted shares outstanding and rising interest rates. The Company reminds investors that the impacts of the COVID-19 pandemic, inflation and general market conditions are uncertain and impossible to predict. See “Forward-looking Statements” below.

Non-GAAP Financial Measures

Funds from Operations (“FFO”) – The National Association of Real Estate Investment Trusts (“NAREIT”) states FFO should represent net income or loss (computed in accordance with GAAP) plus real estate related depreciation and amortization (excluding amortization of deferred financing costs) and after adjustments of unconsolidated partnerships and joint ventures, gains or losses on the sale of property and impairments to real estate.

The Company uses FFO as a supplemental performance measure because the Company believes that FFO is beneficial to investors as a starting point in measuring the Company’s operational performance. We also believe that, as a widely recognized measure of the performance of REITs, FFO will be used by investors as a basis to compare the Company’s operating performance with that of other REITs.

4

However, because FFO excludes depreciation and amortization and captures neither the changes in the value of the Company’s properties that result from use or market conditions nor the level of capital expenditures and leasing commissions necessary to maintain the operating performance of the Company’s properties, all of which have real economic effects and could materially impact the Company’s results from operations, the utility of FFO as a measure of the Company’s performance is limited. In addition, other equity REITs may not calculate FFO in accordance with the NAREIT definition as the Company does, and, accordingly, the Company’s FFO may not be comparable to such other REITs’ FFO. Accordingly, FFO should be considered only as a supplement to net income as a measure of the Company’s performance.

Core Funds from Operations (“Core FFO”) – We calculate Core FFO by using FFO as defined by NAREIT and adjusting for certain other non-core items. We also exclude from our Core FFO calculation acquisition costs, loss on early extinguishment of debt, changes in the fair value of earn-outs, changes in fair value of contingent consideration and the amortization of stock based compensation.

We believe Core FFO provides a useful metric in comparing operations between reporting periods and in assessing the sustainability of our ongoing operating performance. Other equity REITs may calculate Core FFO differently or not at all, and, accordingly, the Company’s Core FFO may not be comparable to such other REITs’ Core FFO.

Adjusted Funds from Operations (“AFFO”) – We compute AFFO by adding to Core FFO the non-cash amortization of deferred financing fees and non-real estate depreciation and then subtracting cash paid for recurring tenant improvements, leasing commissions, and capital expenditures, and eliminating the net effect of straight-line rent / expense, deferred market rent and debt fair value amortization. Recurring capital expenditures exclude development / redevelopment activities, capital expenditures planned at acquisition and costs to reposition a property. We exclude first generation leasing costs within the first two years of acquisition, which are generally to fill vacant space in properties we acquire or were planned at acquisition. We have further excluded all costs associated with tenant improvements, leasing commissions and capital expenditures which were funded by the entity contributing the properties at closing.

Along with FFO and Core FFO, we believe AFFO provides investors with appropriate supplemental information to evaluate the ongoing operations of the Company. Other equity REITs may calculate AFFO differently, and, accordingly, the Company’s AFFO may not be comparable to such other REITs’ AFFO.

Net Operating Income (“NOI”), Adjusted Cash NOI (CIO share) – We define NOI as rental and other revenues less property operating expenses. We define Adjusted Cash NOI as NOI less the effect of recurring straight-line rent / expense, deferred market rent, and any amounts which are funded by the selling entities and NCI in properties.

We consider NOI and Adjusted Cash NOI to be appropriate supplemental performance measures to net income because we believe they provide information useful in understanding the core operations and operating performance of our portfolio.

Same Store Net Operating Income (“Same Store NOI”) and Same Store Cash Net Operating Income (“Same Store Cash NOI”) – Same Store NOI and Same Store Cash NOI are calculated as the NOI attributable to the properties continuously owned and operated for the entirety of the reporting periods presented. The Company’s definition of Same Store NOI and Same Store Cash NOI excludes properties that were not stabilized during both of the applicable reporting periods. These exclusions may include, but are not limited to, acquisitions, dispositions and properties undergoing repositioning or significant renovations.

5

We believe Same Store NOI and Same Store Cash NOI are important measures of comparison because it allows for comparison of operating results of stabilized properties owned and operated for the entirety of both applicable periods and therefore eliminates variations caused by acquisitions, dispositions or repositionings during such periods. Other REITs may calculate Same Store NOI and Same Store Cash NOI differently and our calculation should not be compared to that of other REITs.
