Forward Looking Statements This presentation contains statements that are not historical facts and may be forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995, including statements regarding the timing, ability to consummate and consideration related to our anticipated acquisitions and dispositions, the intent, belief or current expectations of us, our operating partnership and members of our management team, our business and growth strategies, and our investment and financing activites, as well as the assumptions on which such statements are based, and generally are identified by the use of words such as “may,” “will,” “seeks,” “anticipates,” “believes,” “expects,” “estimates,” “projects,” “potential,” “predicts,” “plans,” “intends,” “would,” “could,” “should” or similar expressions are intended to identify forward-looking statements, although not all forward-looking statements contain these identifying words. These forward-looking statements are subject to risks, uncertainties, and other factors, many of which are outside of our control, which could cause actual results to differ materially from the results contemplated by the forward-looking statements. These risks and uncertainties include the risks that any potential future acquisition or disposition by us is subject to market conditions, capital availability and timing considerations and may not be identified or completed on favorable terms, or at all. Some of the risks and uncertainties, although not all risks and uncertainties, that could cause our actual results to differ materially from those presented in our forward-looking statements are set forth under “Risk Factors”, “Management’s Discussion and Analysis of Financial Condition and Results of Operations” and “Quantitative and Qualitative Disclosures about Market Risk” sections in our Annual Report on Form 10-K for the year ended December 31, 2025, filed with the SEC on February 25, 2026, our Quarterly Reports on Form 10-Q and our other filings with the U.S. Securities and Exchange Commission (“SEC”) as such risks, uncertainties and other important factors may be updated from time to time in our subsequent reports. Further, forward-looking statements speak only as of the date they are made, and we undertake no obligation to update or revise any forward-looking statement to reflect changed assumptions, the occurrence of unanticipated events or changes to future operating results over time, unless required by law. Projections This presentation also includes estimated projections of future operating results. These projections are not prepared in accordance with published guidelines of the SEC or the guidelines established by the American Institute of Certified Public Accountants for preparation and presentation of financial projections. This information is not fact and should not be relied upon as being necessarily indicative of future results; the projections were prepared in good faith by management and are based on numerous assumptions that may prove to be wrong. All such statements, including but not limited to estimates of value accretion, synergies, run-rate or annualized figures and results of future operations after making adjustments to give effect to assumed future operations reflect assumptions as to certain business decisions and events that are subject to change. As a result, actual results may differ materially from those contained in the estimates. Accordingly, there can be no assurance that the estimates will be realized, or that the projections described in this presentation will be realized at all. This presentation also contains estimates and information concerning our industry and tenants, including market position, market size and growth rates of the markets in which we operate, that are based on industry publications and other third-party reports. This information involves a number of assumptions and limitations, and you are cautioned not to give undue weight to these estimates. We have not independently verified the accuracy or completeness of the data contained in these publications and reports. The industry in which we operate is subject to a high degree of uncertainty and risk due to a variety of factors, including those described in the “Risk Factors”, “Management’s Discussion and Analysis of Financial Condition and Results of Operations” and “Quantitative and Qualitative Disclosures about Market Risk” sections of the Company’s Annual Report on Form 10-K, and all of its other filings with the SEC, as such risks, uncertainties and other important factors may be updated from time to time in the Company’s subsequent reports. Credit Ratings A securities rating is not a recommendation to buy, sell or hold securities and may be subject to revision or withdrawal at any time. Each rating agency has its own methodology of assigning ratings and, accordingly, each rating should be evaluated independently of any other rating. Q4 2025 2

Track Record of Delivering on Strategic Goals Q4 2025 4 Successful Disposition Program Since launching its disposition program, GNL has completed approximately $3.4 billion in sales, highlighted by the $1.8 billion Multi-Tenant Retail Portfolio sale, which accelerated debt reduction efforts and materially strengthened the balance sheet and portfolio Significant Leverage Reduction GNL has prioritized deploying net proceeds from non-core asset sales toward debt reduction, lowering Net Debt to Adjusted EBITDA by nearly two turns since the end of Q4’23, going from 8.4x to 6.7x, and materially strengthening its overall leverage profile Accretive Share Repurchase Program GNL deploys a portion of net proceeds from non-core asset sales to accretively repurchase shares, having repurchased 17.2 million shares for $136 million at a weighted average price of $7.88(1) 2025 in Review Throughout 2025, GNL undertook a broad set of actions that collectively repositioned the Company – elevating overall quality through a more streamlined portfolio, a materially lower leverage profile, enhanced liquidity and improved credit metrics 1.

We do not provide guidance on net income. We only provide guidance on AFFO per share and our Net Debt to Adjusted EBITDA ratio and do not provide reconciliations of this forward-looking non-GAAP guidance to net income per share or our debt to net income due to the inherent difficulty in quantifying certain items necessary to provide such reconciliations as a result of their unknown effect, timing and potential significance. Examples of such items include impairment of assets, gains and losses from sales of assets, and depreciation and amortization from new acquisitions and other non-recurring expenses. 2. Adjusted EBITDA annualized based on forecasted Adjusted EBITDA for the quarter ended December 31, 2026 multiplied by four. Annualized figures based on assumed future operations that reflect assumptions as to certain business decisions and events that are subject to change. There can be no assurance that these annualized figures will prove to be accurate. 3. 2026 full year guidance based on gross transaction volume of $250 million and $350 million, inclusive of both dispositions and acquisitions.

Implied investment grade may include actual ratings of tenant parent, guarantor parent (regardless of whether or not the parent has guaranteed the tenant's obligation under the lease) or by using a proprietary Moody's analytical tool, which generates an implied rating by measuring a company's probability of default. The term "parent" for these purposes includes any entity, including any governmental entity, owning more than 50% of the voting stock in a tenant or a guarantor. Based on annualized SLR and as of December 31, 2025, GNL’s portfolio was 34% actual investment grade rated and 32% implied investment grade rated.

Financial Definitions Non-GAAP Financial Measures This presentation includes various performance indicators and non-GAAP financial measures that we use to help us evaluate our performance, ability to incur and service debt, financial condition and results of operations. These non-GAAP financial measures include Funds from Operations (“FFO”), Core Funds from Operations (“Core FFO”), Adjusted Funds from Operations (“AFFO”), Adjusted Earnings before Interest, Taxes, Depreciation and Amortization (“Adjusted EBITDA”), Net Operating Income (“NOI”), Cash Net Operating Income (“Cash NOI”) and Cash Paid for Interest. While NOI is a property-level measure, AFFO is based on total Company performance and therefore reflects the impact of other items not specifically associated with NOI such as, interest expense, general and administrative expenses and operating fees to related parties. Additionally, NOI does not reflect an adjustment for straight-line rent, but AFFO does include this adjustment. FFO, Core FFO, AFFO, Adjusted EBITDA, NOI and Cash NOI and pro forma presentations of the foregoing are financial measures that are calculated and presented on the basis of methodologies other than in accordance with generally accepted accounting principles in the United States of America (“GAAP”). Definitions of such non-GAAP measures can be found in the Company’s Q4 2025 earnings release for the quarter ended December 31, 2025, furnished as exhibit 99.1 to the Current Report on Form 8-K filed on February 25, 2026. Reconciliations of such non-GAAP measures for Q4 2025 to their nearest comparable GAAP measures can be found in the Appendix found within, and with respect to the quarterly information regarding Q4 2024, the reconciliations can be found in the Company’s earnings release for the quarter ended December 31, 2024, furnished as exhibit 99.1 to the Current Report on Form 8-K filed with the SEC on February 27, 2025. Any non-GAAP financial measures used in this presentation are in addition to, and not meant to be considered superior to, or a substitute for, the Company’s financial statements prepared in accordance with GAAP. Additional information with respect to the Company is contained in its filings with the SEC and is available at the SEC's website, www.sec.gov, and on the Company’s website, https://www.globalnetlease.com/. Caution on Use of Non-GAAP Measures FFO, Core FFO, AFFO, Adjusted EBITDA, NOI, Cash NOI and Cash Paid for Interest should not be construed to be more relevant or accurate than the current GAAP methodology in calculating net income or in its applicability in evaluating our operating performance. The method utilized to evaluate the value and performance of real estate under GAAP should be construed as a more relevant measure of operational performance and considered more prominently than the non-GAAP measures. Other REITs may not define FFO in accordance with the current National Association of Real Estate Investment Trusts (“NAREIT”) definition (as we do) or may interpret the current NAREIT definition differently than we do or may calculate Core FFO or AFFO differently than we do. Consequently, our presentation of FFO, Core FFO and AFFO may not be comparable to other similarly-titled measures presented by other REITs. We consider FFO, Core FFO and AFFO useful indicators of our performance. Because FFO, Core FFO and AFFO calculations exclude such factors as depreciation and amortization of real estate assets and gain or loss from sales of operating real estate assets (which can vary among owners of identical assets in similar conditions based on historical cost accounting and useful-life estimates), FFO, Core FFO and AFFO presentations facilitate comparisons of operating performance between periods and between other REITs in our peer group.

Represents deferred tax expense specifically related to the capital gain recorded upon the disposition of the McLaren campus. This amount is recorded in the income tax expense line item in our consolidated statements of operations. We do not consider this expense to be part of our normal operating performance and have, accordingly, increased AFFO for this amount. 3. Represents adjustments to the fair value of the embedded derivative feature of the multi-tenant disposition receivable. We do not consider these adjustments to be indicative of our normal operating performance and have, accordingly, increased AFFO for this amount.
