Safe Harbor Certain statements contained in this press release (other than statements of historical fact) are forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended and Section 21E of the Securities Exchange Act of 1934, as amended. Forward-looking statements can typically be identified by words such as “believe,” “estimate,” “expect,” “intend,” “anticipate,” “will,” “could,” “may,” “should,” “plan,” “potential,” “predict,” “forecast,” “project,” and similar expressions, as well as variations or negatives of these words. Although forward-looking statements are made based upon management’s present expectations and reasonable beliefs concerning future developments and their potential effect upon the Company, a number of factors could cause the Company’s actual results to differ materially from those set forth in the forward-looking statements. Such factors may include, but are not limited to: the Company’s ability to remain qualified as a REIT; the Company’s exposure to U.S. federal and state income tax law changes, including changes to the REIT requirements; general adverse economic and real estate conditions; the ultimate geographic spread, severity and duration of pandemics such as the recent outbreak of the novel coronavirus, actions that may be taken by governmental authorities to contain or address the impact of such pandemics, and the potential negative impacts of such pandemics on the global economy and the Company’s financial condition and results of operations; the inability of major tenants to continue paying their rent or obligations due to bankruptcy, insolvency or a general downturn in their business; the loss or failure, or decline in the business or assets of PINE or the venture formed when the Company sold its controlling interest in the entity that owned the Company’s remaining land portfolio, of which the Company has a retained interest; the completion of 1031 exchange transactions; the availability of investment properties that meet the Company’s investment goals and criteria; the uncertainties associated with obtaining required governmental permits and satisfying other closing conditions for planned acquisitions and sales; and the uncertainties and risk factors discussed in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2020 and other risks and uncertainties discussed from time to time in the Company’s filings with the U.S. Securities and Exchange Commission. There can be no assurance that future developments will be in accordance with management’s expectations or that the effect of future developments on the Company will be those anticipated by management. Readers are cautioned not to place undue reliance on these forward-looking statements, which speak only as of the date of this press release. The Company undertakes no obligation to update the information contained in this press release to reflect subsequently occurring events or circumstances. Non-GAAP Financial Measures Our reported results are presented in accordance with accounting principles generally accepted in the United States of America (“GAAP”). We also disclose Funds From Operations (“FFO”) and Adjusted Funds From Operations (“AFFO”), both of which are non-GAAP financial measures. We believe these two non-GAAP financial measures are useful to investors because they are widely accepted industry measures used by analysts and investors to compare the operating performance of REITs. FFO and AFFO do not represent cash generated from operating activities and are not necessarily indicative of cash available to fund cash requirements; accordingly, they should not be considered alternatives to net income as a performance measure or cash flows from operating activities as reported on our statement of cash flows as a liquidity measure and should be considered in addition to, and not in lieu of, GAAP financial measures. We compute FFO in accordance with the definition adopted by the Board of Governors of the National Association of Real Estate Investment Trusts, or NAREIT. NAREIT defines FFO as GAAP net income or loss adjusted to exclude extraordinary items (as defined by GAAP), net gain or loss from sales of depreciable real estate assets, impairment write-downs associated with depreciable real estate assets and real estate related depreciation and amortization, including the pro rata share of such adjustments of unconsolidated subsidiaries. The Company also excludes the gains or losses from sales of assets incidental to the primary business of the REIT which specifically include the sales of mitigation credits, impact fee credits, subsurface sales, and the land sales gains included in discontinued operations. To derive AFFO, we modify the NAREIT computation of FFO to include other adjustments to GAAP net income related to non-cash revenues and expenses such as straight-line rental revenue, amortization of deferred financing costs, amortization of capitalized lease incentives and above- and below-market lease related intangibles, and non-cash compensation. Such items may cause short-term fluctuations in net income but have no impact on operating cash flows or long-term operating performance. We use AFFO as one measure of our performance when we formulate corporate goals. FFO is used by management, investors and analysts to facilitate meaningful comparisons of operating performance between periods and among our peers primarily because it excludes the effect of real estate depreciation and amortization and net gains or losses on sales, which are based on historical costs and implicitly assume that the value of real estate diminishes predictably over time, rather than fluctuating based on existing market conditions. We believe that AFFO is an additional useful supplemental measure for investors to consider because it will help them to better assess our operating performance without the distortions created by other non-cash revenues or expenses. FFO and AFFO may not be comparable to similarly titled measures employed by other companies. 3 For the Quarter Ended September 30, 2021

Definitions and Terms 27 Annualized Base Rent (ABR) is the annual straight-line recognition of a lease’s minimum base rent as calculated based on the leases in-place within the Company’s portfolio as of the end of the reporting period. Funds From Operations (FFO) and Adjusted Funds From Operations (AFFO) are both non-GAAP financial measures. We believe these two non-GAAP financial measures are useful to investors because they are widely accepted industry measures used by analysts and investors to compare the operating performance of REITs. FFO and AFFO do not represent cash generated from operating activities and are not necessarily indicative of cash available to fund cash requirements; accordingly, they should not be considered alternatives to net income as a performance measure or cash flows from operating activities as reported on our statement of cash flows as a liquidity measure and should be considered in addition to, and not in lieu of, GAAP financial measures. We compute FFO in accordance with the definition adopted by the Board of Governors of the National Association of Real Estate Investment Trusts, or NAREIT. NAREIT defines FFO as GAAP net income or loss adjusted to exclude extraordinary items (as defined by GAAP), net gain or loss from sales of depreciable real estate assets, impairment write- downs associated with depreciable real estate assets and real estate related depreciation and amortization, including the pro rata share of such adjustments of unconsolidated subsidiaries. The Company also excludes the gains or losses from sales of assets incidental to the primary business of the REIT which specifically include the sales of mitigation credits, impact fee credits, subsurface sales, and the land sales gains included in discontinued operations. To derive AFFO, we modify the NAREIT computation of FFO to include other adjustments to GAAP net income related to non-cash revenues and expenses such as straight-line rental revenue, amortization of deferred financing costs, amortization of capitalized lease incentives and above- and below-market lease related intangibles, and non-cash compensation. Such items may cause short-term fluctuations in net income but have no impact on operating cash flows or long-term operating performance. We use AFFO as one measure of our performance when we formulate corporate goals. FFO is used by management, investors and analysts to facilitate meaningful comparisons of operating performance between periods and among our peers primarily because it excludes the effect of real estate depreciation and amortization and net gains on sales, which are based on historical costs and implicitly assume that the value of real estate diminishes predictably over time, rather than fluctuating based on existing market conditions. We believe that AFFO is an additional useful supplemental measure for investors to consider because it will help them to better assess our operating performance without the distortions created by other non-cash revenues or expenses. FFO and AFFO may not be comparable to similarly titled measures employed by other companies. Net Debt is calculated as our gross debt at face value and before the effects of net deferred financing costs, less cash, cash equivalents and restricted cash. We believe it is appropriate to exclude cash, cash equivalents and restricted cash from gross debt because the cash, cash equivalents and restricted cash could be used to repay debt. We believe net debt is a beneficial disclosure because it represents the contractual obligations of the company that would potentially need to be repaid in the future. New Cash Rent PSF is the in-place minimum cash rent of the newly signed lease, divided by the square feet of the unit for which the tenant is occupying. Weighted Average Term is the term of a set of leases, weighted by the amount of in-place annual minimum base rent. For the Quarter Ended September 30, 2021
