In particular, statements in this presentation regarding: our transformation to a transaction-enabled platform; industry trends; our market awareness; our business and growth strategy and our plans to execute on our growth strategy; our ability to grow our business, including CarOffer, profitably and efficiently; the growth levers we expect to drive our business; our brand awareness efforts; our ability to realize marketing spend efficiencies; our investments in and ability to drive adoption of new and existing products and their benefits; the attractiveness and value proposition of our current offerings and other product opportunities; our ability to maintain existing and acquire new customers; addressable opportunities; our ability to innovate and invest in new growth initiatives and long-term growth objectives; synergies that can be created from our combined offerings, including with respect to product synergies, consumer experience, dealer value proposition, new products and revenue opportunities, and other business efficiencies; the potential growth, scaling and efficiency of CarOffer, as well as the value proposition of CarOffer’s business and expected transaction synergies; the potential growth and scaling of CarGurus Instant Max Cash Offer and our Digital Retail product opportunities; our future financial and business performance, including for the second quarter of 2022; our long-term financial targets; the impact of macro-level industry issues on our business and financial results; our belief that the presentation of non-GAAP financial measures and other business metrics is helpful to our investors; and other statements regarding our plans, prospects and expectations, are examples of such forward-looking statements. These forward-looking statements are subject to a number of risks and uncertainties, including, without limitation, risks related to: our growth and ability to grow our revenue; our relationships with dealers; competition in the markets in which we operate; market growth; our ability to innovate; our ability to realize benefits from our acquisitions and successfully implement the integration strategies in connection therewith; natural disasters, epidemics or pandemics, like COVID-19 that has negatively impacted our business; global supply chain challenges, the semiconductor chip shortage, and other macroeconomic issues; our ability to operate in compliance with applicable laws, as well as other risks and uncertainties that we have detailed in the “Risk Factors” section of our Quarterly Report on Form 10-Q, filed on May 9, 2022 with the U.S. Securities and Exchange Commission (“SEC”), and our subsequent filings with the SEC. These factors could cause actual results and developments to be materially different from those expressed in or implied by such statements. Forward-looking statements do not guarantee future performance and actual results may differ materially from those projected. The forward-looking statements are made only as of the date of this presentation, and we undertake no obligation to update such forward-looking statements to reflect subsequent events or circumstance. This presentation also contains estimates and other statistical data, including those relating to our industry and the market in which we operate, that we have obtained or derived from internally-prepared studies and surveys, third-party studies, industry publications and reports, as well as other publicly available information prepared by a number of third-party sources. We rely on both internal data and Google Analytics for data relating to our own key business metrics and, for consistency, we rely on Comscore and, as applicable, third-party studies for data relating to comparisons with our competitors. Google Analytics, Comscore and applicable third-party studies use different methodologies to derive their data and therefore their data for similar statistics are not comparable. These third-party studies and industry publications and reports generally indicate that they have obtained their information from sources believed to be reliable, but do not guarantee the accuracy and completeness of their information. This information involves a number of assumptions and limitations, and you are cautioned not to give undue weight to these estimates, as there is no assurance that any of them will be reached. Based on our experience, we believe that these third-party studies and industry publications and reports are reliable and that the conclusions contained therein are reasonable. In addition, you are cautioned not to rely on our extrapolations of internally-prepared studies and surveys and/or third-party studies, as these are estimates involving a number of assumptions and limitations, which we are unable to ensure will be reached. In addition to the financial measures contained in this presentation that are prepared in accordance with U.S. Generally Accepted Accounting Principles (“GAAP”), this presentation includes certain non-GAAP financial measures and other business metrics. The presentation of non-GAAP financial information and other business metrics is not meant to be considered in isolation or as a substitute for the directly comparable financial measures prepared in accordance with GAAP. While our non-GAAP financial measures and other business metrics are an important tool for financial and operational decision-making and for evaluating our own operating results over different periods of time, we urge investors to review the reconciliation of the non-GAAP financial measures to the comparable GAAP financial measure included in the Appendix to this presentation and not to rely on any single financial measure to evaluate our business.

Please see the Appendix to this presentation for a reconciliation of these non-GAAP measures 2. The assumptions that are built into the long-term targets above are based on recent market behaviors and industry conditions. Long-term targets exclude the effects of significant COVID-19 resurgences, including the reintroduction of lockdowns and/or a slowed pace of recovery, or other macro-level industry issues that result in dealers and consumers materially changing their recent market behaviors or that cause us to enact measures to assist dealers, such as offering fee reductions or waivers as we have done from time to time during the COVID-19 pandemic. Long-term targets also exclude any potential impact of foreign currency exchange gains or losses. CarGurus has not reconciled its long-term targets for non-GAAP gross margins to GAAP gross margins because stock-based compensation and amortization of intangible assets, the reconciling items between such GAAP and non-GAAP financial measures, cannot be reasonably predicted due to the timing, amount, valuation and number of future employee equity awards, and therefore cannot be determined without unreasonable effort. 11 CarGurus®

Please see the Appendix to this presentation for a reconciliation of these non-GAAP measures 2. Inclusive of Digital Retail 3. The assumptions that are built into the long-term targets above are based on recent market behaviors and industry conditions. Long-term targets exclude the effects of significant COVID-19 resurgences, including the reintroduction of lockdowns and/or a slowed pace of recovery, or other macro-level industry issues that result in dealers and consumers materially changing their recent market behaviors or that cause us to enact measures to assist dealers, such as offering fee reductions or waivers as we have done from time to time during the COVID-19 pandemic. Long-term targets also exclude any potential impact of foreign currency exchange gains or losses. CarGurus has not reconciled its long-term targets for: (i) non-GAAP gross margins to GAAP gross margins because stock-based compensation and amortization of intangible assets, the reconciling items between such GAAP and non-GAAP financial measures, cannot be reasonably predicted due to the timing, amount, valuation and number of future employee equity awards, and therefore cannot be determined without unreasonable effort; or (ii) adjusted EBITDA to GAAP net income because stock-based compensation, amortization of intangible assets, acquisition-related expenses, depreciation expenses, non-intangible amortization, other income (net), and the provision for income taxes, the reconciling items between such GAAP and non-GAAP financial measures, cannot be reasonably predicted due to, as applicable, the timing, amount, valuation and number of future employee equity awards, and the uncertainty relating to the timing, frequency and effect of acquisitions, and therefore cannot be determined without unreasonable effort. 80 CarGurus®

Q2 Guidance: updated $ in Millions (*except Non-GAAP EPS) 1Q’2022 2Q’2022 – Original Guidance (5/9/22)1 2Q’2022 - Updated Guidance (5/25/22) Revenue $431 $480 - $510 $490 - $520 IMCO Revenue $162 $219 - $239 $227 - $247 Non–GAAP Operating Income $62 $44 - $52 $48 - $56 Consolidated Adjusted EBITDA $66 N/A $51.5 - $59.5 Non-GAAP EPS $0.36 $0.26 - $0.29 $0.27 - $0.30 1. Prior guidance provided in CarGurus’ first quarter 2022 earnings results call and/or in its earnings press release dated May 9, 2022, furnished as Exhibit 99.1 to CarGurus’ Current Report on Form 8-K filed with the SEC on May 9, 2022. This prior guidance is updated with today’s presentation. Note: The second quarter 2022 non-GAAP EPS calculation assumes 119.5 million diluted weighted-average common shares outstanding. This assumed number of shares outstanding excludes the potential dilution from CarGurus utilizing its equity as the sole form of consideration to purchase the remaining 49% interest in CarOffer, which is assumed for accounting purposes. As of March 31, 2022, there were 7.9 million potentially dilutive shares related to the potential future purchase of the remaining 49% interest in CarOffer, all of which have been excluded from the calculation of the second quarter 2022 non-GAAP EPS calculation as they were anti-dilutive as of such date. The assumptions that are built into guidance for the second quarter 2022 regarding our pace of paid dealer acquisition, churn, and expansion activity for the relevant period are based on recent market behaviors and industry conditions. Guidance for the second quarter 2022 excludes the effects of significant COVID-19 resurgences, including the reintroduction of lockdowns and/or a slowed pace of recovery, or other macro-level industry issues that result in dealers and consumers materially changing their recent market behaviors or that cause us to enact measures to assist dealers, such as offering fee reductions or waivers as we have done from time to time during the COVID-19 pandemic. Guidance also excludes adjustments to the carrying value of redeemable noncontrolling interests resulting from potential changes in the redemption value of such interests, and any potential impact of foreign currency exchange gains or losses. CarGurus has not reconciled its guidance for (i) non-GAAP operating income to GAAP operating income, (ii) consolidated adjusted EBITDA to GAAP consolidated net income, or (iii) non-GAAP EPS to GAAP EPS because the reconciling items between such GAAP and non-GAAP financial measures, which include, as applicable, stock-based compensation, amortization of intangible assets, acquisition-related expenses, depreciation expenses, non-intangible amortization, other income (net), the provision for income taxes, and adjustments to the carrying value of redeemable noncontrolling interests resulting from changes in the redemption value of such interests, cannot be reasonably predicted due to, as applicable, the timing, amount, valuation and number of future employee equity awards, and the uncertainty relating to the timing, frequency and effect of acquisitions and the significance of the resulting acquisition-related expenses, including adjustments to the carrying value of redeemable noncontrolling interests resulting from potential changes in the redemption value of such interests, and therefore cannot be determined without unreasonable effort. 81 CarGurus®

A dealer account that is active with CarGurus’ Restricted listings at the end of a defined period, but does not have an active, paid marketplace subscription at the end of such defined period. Restricted listings do not display the name, address, website URL, or phone number of the relevant dealer and are subject to other limitations. Defined as those for which CarOffer and the applicable dealer have signed an enrollment agreement to participate on the CarOffer platform and CarOffer has entered such dealer’s rooftops in its sales management system. Includes dealers that have signed an enrollment agreement but have not yet completed CarOffer’s onboarding process. The number of vehicles sold through the CarOffer platform (other than those sold by consumers) during the specified time period, based on the date that CarOffer considers the vehicle as sold, which can vary depending on the nature of the transaction. The number of transactions for reported periods is subject to potential adjustment after the date hereof based on future arbitration claims that may occur in the ordinary course. The number of vehicles sold by consumers through the CarOffer platform during the specified time period, based on the date that CarOffer considers the vehicle as sold, which can vary depending on the nature of the transaction. The number of transactions for reported periods is subject to potential adjustment after the date hereof based on future arbitration claims that may occur in the ordinary course. The aggregate of CarOffer Dealer-to-Dealer Transactions and Instant Max Cash Offer Transactions during the specified time period. The number of transactions for reported periods is subject to potential adjustment after the date hereof based on future arbitration claims that may occur in the ordinary course. The aggregate sale price of all vehicles sold through the CarOffer platform during the specified time period, calculated as the sum of each vehicle’s selling price indicated in the CarOffer system of record based on the date on which CarOffer considers the vehicle as sold, which can vary depending on the nature of the transaction. Excludes OfferGuard and Guaranteed Put-Bid contracts, as well as all fees relating to transportation, inspection, and arbitration. Amounts for reported periods are subject to potential adjustment after the date hereof based on future arbitration claims that may occur in the ordinary course.

Definitions CAROFFER AVERAGE TRANSACTIONS PER DEALER (PURCHASES AND SALES) QUARTERLY AVERAGE REVENUE PER SUBSCRIBING DEALER (“QARSD”) AVERAGE MONTHLY SESSIONS AVERAGE MONTHLY UNIQUE USERS The number of CarOffer Total Transactions during the specified time period, divided by the total number of participating dealers in such time period. Participating dealers reflect dealers that purchased or sold at least one vehicle through the CarOffer platform during the specified time period, based on the date that CarOffer considers the vehicle as sold, which can vary depending on the nature of the transaction. The number of transactions for reported periods is subject to potential adjustment after the date hereof based on future arbitration claims that may occur in the ordinary course. We define QARSD, which is measured at the end of a fiscal quarter, as the marketplace revenue primarily from subscriptions to our Listings packages and Real-time Performance Marketing digital advertising suite during that trailing quarter divided by the average number of paying dealers in that marketplace during the quarter. We calculate the average number of paying dealers for a period by adding the number of paying dealers at the end of such period and the end of the prior period and dividing by two. We define monthly sessions as the number of distinct visits to our websites (excluding CarOffer) that take place each month within a given time frame, as measured and defined by Google Analytics. We calculate average monthly sessions as the sum of the monthly sessions in a given period, divided by the number of months in that period. A session is defined as beginning with the first page view from a computer or mobile device and ending at the earliest of when a user closes their browser window, after 30 minutes of inactivity, or each night at midnight (i) Eastern Time for our United States and Canada websites, other than the Autolist website, (ii) Pacific Time for the Autolist website, and (iii) Greenwich Mean Time for our U.K. websites. A session can be made up of multiple page views and visitor actions, such as performing a search, visiting vehicle detail pages, and connecting with a dealer. For each of our websites (excluding CarOffer), we define a monthly unique user (or visitor) as an individual who has visited any such website within a calendar month, based on data as measured by Google Analytics. We calculate average monthly unique users as the sum of the monthly unique users of each of our websites in a given period, divided by the number of months in that period. We count a unique user the first time a computer or mobile device with a unique device identifier accesses any of our websites during a calendar month. If an individual accesses a website using a different device within a given month, the first access by each such device is counted as a separate unique user. If an individual uses multiple browsers on a single device and/or clears their cookies and returns to our site within a calendar month, we count each such visit as a unique user. 91 CarGurus®

We assessed the materiality of these adjustments on our historical financial statements, individually and in aggregate, and concluded the effect was not material for any of the relevant periods. Note: We define non-GAAP Gross Profit Margin for our CarOffer dealer-to-dealer business as non-GAAP Gross Profit for such business divided by GAAP Revenue for such business. We define non-GAAP Gross Profit for our CarOffer dealer-to-dealer business as the difference between GAAP Revenue for such business and GAAP Cost of Revenue for such business adjusted for the impacts of Amortization of Intangible Assets and Stock-Based Compensation Expense in GAAP Cost of Revenue for such business.
