The Company has based these forward-looking statements largely on its estimates of its financial results and its current expectations and projections about future events and financial trends that it believes may affect its financial condition, results of operations, business strategy, short-term and long-term business operations and objectives and financial needs. These forward-looking statements are subject to a number of risks, uncertainties and assumptions, including fluctuations in the number of COVID-19 cases and the spread of COVID-19 variants, the COVID-19 vaccination rate in the United States, the timeframe for the lifting of COVID-19-related public health restrictions and the pace of economic recovery in local economies and the United States generally; the impact of fear or actual outbreaks of diseases, including the COVID-19 pandemic and any variants thereof, and any resulting changes in consumer behavior, economic conditions or governmental actions; our ability to maintain and expand our base of advertisers, particularly as many businesses continue to face operating restrictions in connection with the COVID-19 pandemic and other constraints; our ability to continue to effectively operate with a primarily remote work force and attract and retain key talent; our limited operating history in an evolving and competitive industry; our ability to generate and maintain sufficient high-quality content from our users; our reliance on traffic from search engines like Google and Bing and the quality and reliability of such traffic; our ability to manage acquisitions of new businesses, solutions or technologies and to integrate and monetize those businesses, solutions or technologies; our ability to timely upgrade and develop our systems, infrastructure and customer service capabilities; our ability to maintain a strong brand and manage negative publicity that may arise; and changes in political, business and economic conditions. These risks and uncertainties may also include those described in the Company's most recent Form 10-Q or Form 10-K filed with the Securities and Exchange Commission. New risks emerge from time to time. It is not possible for Company management to predict all risks, nor can the Company assess the impact of all factors on its 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 the Company may make. In light of these risks, uncertainties and assumptions, the forward-looking events and circumstances discussed in these slides and the accompanying oral presentation may not occur and actual results could differ materially and adversely from those anticipated or implied in the forward-looking statements. You should not rely upon forward-looking statements as predictions of future events. Although the Company believes that the expectations reflected in the forward-looking statements are reasonable, the Company 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 the Company nor any other person assumes responsibility for the accuracy and completeness of the forward-looking statements. Any forward-looking statement speaks only as of its date. Except as required by law, the Company undertakes no obligation to update publicly any forward-looking statements for any reason after the date of this presentation, to conform these statements to actual results or to changes in the Company's expectations. 2#3Key investment highlights Trusted Content Well-known brand and trusted content provide competitive moat and lower traffic acquisition cost Broad-based Local Ad Platform Large, high-intent consumer audience supports broad-based advertising model with large TAM and significant monetization opportunity Sustainable Growth Portfolio of product initiatives to drive sustainable, profitable growth over the long term Transformed Business Model Consistent execution of strategic initiatives has driven structural efficiency through product innovation and sales channel mix 'As of December 31, 2021 Prudent Capital Allocation Nearly $1 billion returned to shareholders through repurchases¹ Strong Governance Talented Board with diverse skill set and focus on performance, including ESG and Yelp's mission in our local communities 3#4About Yelp#5Yelp is all things local We serve a wide variety of consumers' and businesses' local needs Landscaping Near Me E Sponsored Results Shoe's Bloomers (923) Verified License 0.1 mi Landscaping 30 years in business Free estimates Response time 10 mins Response rate 100% Request a quote = Home Delivery Me Collections More Consumers Search Discovery Request-A-Quote Table booking Food ordering ← 9:41 Penelope's request Local Biz Large consumer audience Visibility High-intent leads Table management Food orders Hi there, please respond with a price. estimate.

We define Adjusted EBITDA margin as Adjusted EBITDA divided by Net revenue. This presentation includes Adjusted EBITDA and Adjusted EBITDA margin, each of which is a "non-GAAP financial measure." Adjusted EBITDA is not prepared under any comprehensive set of accounting rules or principles, has limitations as an analytical tool, and you should not consider it in isolation or as a substitute for analysis of Yelp's results as reported under GAAP. In particular, Adjusted EBITDA should not be viewed as a substitute for, or superior to, GAAP Net income (loss) as a measure of profitability of liquidity. You can read more about the limitations of Adjusted EBITDA, as well as the basis of presentation of the numbers in the table above, in Yelp's most recent Annual Report on Form 10-K or Quarterly Report on Form 10-Q at www.yelp-ir.com or the SEC's website at www.sec.gov. Because of these limitations, you should consider Adjusted EBITDA and Adjusted EBITDA margin alongside other financial performance measures, including various cash flow metrics, Net income (loss) and Yelp's other GAAP results. Amounts have not been recast in accordance with Accounting Standards Update 2014-09, "Revenue from Contracts with Customers (ASC 606)." 39
