Investor Presentation Through Second Quarter 2021 Exhibit 99.1

2 This presentation and the accompanying oral presentation includes forward-looking statements within the meaning of Section 27A of the Securities Act, Section 21E of the Exchange Act and the safe harbor provisions of the U.S. Private Securities Litigation Reform Act of 1995, that relate to our current expectations and views of future events. All statements other than statements of historical facts contained in this presentation, including statements regarding our future results of operations and financial position, industry dynamics, business strategy and plans and our objectives for future operations, are forward-looking statements. These statements represent our opinions, expectations, beliefs, intentions, estimates or strategies regarding the future, which may not be realized. In some cases, you can identify forward-looking statements by terms such as “believe,” “may,” “estimate,” “continue,” “anticipate,” “intend,” “should,” “plan,” “expect,” “predict,” “potential,” “could,” “will,” “would,” “ongoing,” “future” or the negative of these terms or other similar expressions that are intended to identify forward-looking statements, although not all forward-looking statements contain these identifying words. Forward-looking statements are based largely on our current expectations and projections about future events and financial trends that we believe may affect our financial condition, results of operations, business strategy, short-term and long-term business operations and objectives and financial needs. These forward-looking statements involve known and unknown risks, uncertainties, contingencies, changes in circumstances that are difficult to predict and other important factors that may cause our actual results, performance or achievements to be materially and/or significantly different from any future results, performance or achievements expressed or implied by the forward-looking statement. Such risks include our ability to manage expansion into the U.S. markets and other markets; compete in our industry; our expectations regarding our financial performance, including our revenue, costs, EBITDA, Adjusted EBITDA, Adjusted EBITDA Margin and Free Cash Flow; the sufficiency of our cash, cash equivalents, and investments to meet our liquidity needs; mitigate and address unanticipated performance problems on our websites, or platforms; attract, retain, and maintain good relations with our customers; anticipate market needs or develop new or enhanced offerings and services to meet those needs; stay in compliance with laws and regulations, including tax laws, that currently apply or may become applicable to our business both in the U.S. and internationally and our expectations regarding various laws and restrictions that relate to our business; anticipate the effects of existing and developing laws and regulations, including with respect to taxation, and privacy and data protection that relate to our business; obtain and maintain licenses or approvals with gambling authorities in the U.S.; effectively manage our growth and maintain our corporate culture; identify, recruit, and retain skilled personnel, including key members of senior management; our ability to successfully identify, manage, consummate and integrate any existing and potential acquisitions; our ability to maintain, protect, and enhance our intellectual property; our intended use of the net proceeds from this offering; our ability to manage the increased expenses associated and compliance demands with being a public company; our ability to maintain our foreign private issuer status; and other important risk factors discussed under the caption “Risk Factors” in Gambling.com Group’s prospectus pursuant to Rule 424(b) filed with the US Securities and Exchange Commission (“SEC”) on July 23, 2021. Moreover, we operate in a very competitive and rapidly changing environment. New risks emerge from time to time. It is not possible for our management to predict all risks, nor can we assess the impact of all factors on our business or the extent to which any factor, or combination of factors, may cause actual results to differ materially from those contained in any forward-looking statements we may make. In light of these risks, uncertainties and assumptions, the forward-looking events and circumstances discussed in this presentation may not occur and actual results could differ materially and adversely from those anticipated or implied in the forward-looking statements. We caution you therefore against relying on these forward-looking statements, and we qualify all of our forward-looking statements by these cautionary statements. The forward-looking statements included in this presentation are made only as of the date hereof. Although we believe that the expectations reflected in the forward-looking statements are reasonable, we cannot guarantee that the future results, levels of activity, performance or events and circumstances reflected in the forward-looking statements will be achieved or occur. Moreover, neither we nor our advisors nor any other person assumes responsibility for the accuracy and completeness of the forward-looking statements. Neither we nor our advisors undertake any obligation to revise, supplement or update any forward-looking statements for any reason after the date of this presentation to conform these statements to actual results or to changes in our expectations, even if new information becomes available in the future, except as may be required by law. You should read this presentation with the understanding that our actual future results, levels of activity, performance and events and circumstances may be materially different from what we expect. Unless otherwise indicated, information contained in this presentation concerning our industry, competitive position and the markets in which we operate is based on information from independent industry and research organizations, other third-party sources and management estimates. Management estimates are derived from publicly available information released by independent industry analysts and other third-party sources, as well as data from our internal research, and are based on assumptions made by us upon reviewing such data, and our experience in, and knowledge of, such industry and markets, which we believe to be reasonable. In addition, projections, assumptions and estimates of the future performance of the industry in which we operate and our future performance are necessarily subject to uncertainty and risk due to a variety of factors, including those described above. These and other factors could cause results to differ materially from those expressed in the estimates made by independent parties and by us. Industry publications, research, surveys and studies generally state that the information they contain has been obtained from sources believed to be reliable, but that the accuracy and completeness of such information is not guaranteed. Forecasts and other forward-looking information obtained from these sources are subject to the same qualifications and uncertainties as the other forward-looking statements in this presentation. The trademarks included herein are the property of the owners thereof and are used for reference purposes only. Non-IFRS Financial Measures Management uses several financial measures, both IFRS and non-IFRS financial measures, in analyzing and assessing the overall performance of the business and for making operational decisions. EBITDA is a non-IFRS financial measure defined as earnings excluding net finance costs, income tax charge, depreciation, and amortization. Adjusted EBITDA is a non-IFRS financial measure defined as EBITDA adjusted to exclude the effect of non-recurring items, significant non-cash items, share-based payment expense and other items that our board of directors believes do not reflect the underlying performance of the business. Adjusted EBITDA Margin is a non-IFRS measure defined as Adjusted EBITDA as a percentage of revenue.   We believe EBITDA, Adjusted EBITDA and Adjusted EBITDA Margin are useful to our management as a measure of comparative operating performance from period to period as they remove the effect of items not directly resulting from our core operations including effects that are generated by differences in capital structure, depreciation, tax effects and non-recurring events.   While we use EBITDA, Adjusted EBITDA and Adjusted EBITDA Margin as tools to enhance our understanding of certain aspects of our financial performance, we do not believe that EBITDA, Adjusted EBITDA and Adjusted EBITDA Margin are substitutes for, or superior to, the information provided by IFRS results. As such, the presentation of EBITDA, Adjusted EBITDA and Adjusted EBITDA Margin is not intended to be considered in isolation or as a substitute for any measure prepared in accordance with IFRS. The primary limitations associated with the use of EBITDA, Adjusted EBITDA and Adjusted EBITDA Margin as compared to IFRS results are that EBITDA, Adjusted EBITDA and Adjusted EBITDA Margin as we define them may not be comparable to similarly titled measures used by other companies in our industry and that EBITDA, Adjusted EBITDA and Adjusted EBITDA Margin may exclude financial information that some investors may consider important in evaluating our performance.   Free Cash Flow Free Cash Flow is a non-IFRS financial measure defined as cash flow from operating activities less capital expenditures, or CAPEX. We believe Free Cash Flow is useful to our management as a measure of financial performance as it measures our ability to generate additional cash from our operations. While we use Free Cash Flow as a tool to enhance our understanding of certain aspects of our financial performance, we do not believe that Free Cash Flow is a substitute for, or superior to, the information provided by IFRS metrics. As such, the presentation of Free Cash Flow is not intended to be considered in isolation or as a substitute for any measure prepared in accordance with IFRS.   The primary limitation associated with the use of Free Cash Flow as compared to IFRS metrics is that Free Cash Flow does not represent residual cash flows available for discretionary expenditures due to the fact that the measure does not deduct the payments required for debt service and other obligations or payments made for business acquisitions. Free Cash Flow as we define it also may not be comparable to similarly titled measures used by other companies in the online gambling affiliate industry.   Adjusted figures represent non-IFRS information. See the tables at the end of this presentation for an explanation of the adjustments and reconciliations to the comparable numbers. Safe Harbor Statement
