Forward Looking Statements

This letter contains forward-looking statements within the meaning of the Securities Act of 1933, as amended, the Securities Exchange Act of 1934, as amended, and the Private Securities Litigation Reform Act of 1995. Forward-looking statements generally relate to future events or Reddit's future financial or operating performance. In some cases, you can identify forward-looking statements because they contain words such as "may," "will," "should," "expects," "plans," "anticipates," "going to," "could," "intends," "target," "projects," "contemplates," "believes," "estimates," "predicts," "potential" or "continue" or the negative of these words or other similar terms or expressions that concern Reddit's expectations, strategy, priorities, plans or intentions. Forward-looking statements in this release include, but are not limited to, statements regarding Reddit’s priorities, future financial and operating performance, including headcount strategy, breakeven performance objective, capitalization of training data, evolution of AI, international growth strategies to increase content consumption and improve local user experience, consumer product strategy with respect to growth and engagement, GAAP and non-GAAP guidance, strategies, and expectations of growth. Reddit's expectations and beliefs regarding these matters may not materialize, and actual results in future periods are subject to risks and uncertainties that could cause actual results to differ materially from those projected, including those more fully described under the caption “Risk Factors” and elsewhere in documents that Reddit files with the Securities and Exchange Commission (the “SEC”) from time to time, including Reddit’s Quarterly Report on Form 10-Q for the quarter ended March 31, 2024, which is being filed with the SEC at or around the date hereof. The forward-looking statements in this release are based on information available to Reddit as of the date hereof, and Reddit undertakes no obligation to update any forward-looking statements, except as required by law.

A Note About Metrics

We define a daily active unique (“DAUq”) as a user whom we can identify with a unique identifier who has visited a page on the Reddit website, www.reddit.com, or opened a Reddit application at least once during a 24-hour period. Average DAUq for a particular period is calculated by adding the number of DAUq on each day of that period and dividing that sum by the number of days in that period.

We define a weekly active unique (“WAUq”) as a user whom we can identify with a unique identifier who has visited a page on the Reddit website, www.reddit.com, or opened a Reddit application at least once during a trailing seven-day period. Average quarterly WAUq for a particular period is calculated by adding the number of WAUq on each day of that period and dividing that sum by the number of days in that period.

We define average revenue per unique (“ARPU”) as quarterly revenue in a given geography divided by the average DAUq in that geography. For the purposes of calculating ARPU, advertising revenue in a given geography is based on the geographic location in which advertising impressions are delivered, as this approximates revenue based on user activity, while other revenue in a given geography is based on the billing address of the customer.

Use of Non-GAAP Financial Measures

We use certain non-GAAP financial measures to supplement our consolidated financial statements, which are presented in accordance with U.S. GAAP, to evaluate our core operating performance. These non-GAAP financial measures include Adjusted EBITDA, Free Cash Flow, non-GAAP gross profit, non-GAAP gross margin, non-GAAP operating expense, non-GAAP research and development expense, non-GAAP sales and marketing expense, and non-GAAP general and administrative expense. We use these non-GAAP financial measures to facilitate reviews of our operational performance and as a basis for strategic planning. By excluding certain items that are non-recurring or not reflective of the performance of our normal course of business, we believe that these non-GAAP financial measures provide meaningful supplemental information regarding our performance. Accordingly, we believe these non-GAAP financial measures are useful to investors and others because they allow investors to supplement their understanding of our financial trends and evaluate our ongoing and future performance in the same manner as management. However, there are a number of limitations related to the use of non-GAAP financial measures as they

reflect the exercise of judgment by our management about which expenses are excluded or included in determining these non-GAAP measures. These non-GAAP measures should be considered in addition to, not as a substitute for or in isolation from, our financial results prepared in accordance with U.S. GAAP. Other companies, including companies in our industry, may calculate these non-GAAP financial measures differently or not at all, which reduces their usefulness as comparative measures.

A reconciliation is provided in the Appendix for each historical non-GAAP financial measure to the most directly comparable financial measure stated in accordance with U.S. GAAP. Reddit encourages investors to review the related U.S. GAAP financial measures and the reconciliation of these non-GAAP financial measures to their most directly comparable U.S. GAAP financial measures, and not to rely on any single financial measure to evaluate Reddit’s business. We have not provided a reconciliation to the forward-looking GAAP equivalent measures for our non-GAAP guidance due to uncertainty regarding, and the potential variability of, reconciling items. Therefore, a reconciliation of these non-GAAP guidance measures to their corresponding GAAP guidance measures is not available without unreasonable effort.

Adjusted EBITDA is defined as net income (loss) excluding interest (income) expense, net, income tax expense (benefit), depreciation and amortization, stock-based compensation expense and related taxes, other (income) expense, net, and certain other non-recurring or non-cash items impacting net income (loss) that we do not consider indicative of our ongoing business performance. Other (income) expense, net consists primarily of realized gains and losses on sales of marketable securities, foreign currency transaction gains and losses, and other income and expense that are not indicative of our core operating performance. We consider the exclusion of certain non-recurring or non-cash items in calculating Adjusted EBITDA to provide a useful measure for investors and others to evaluate our operating results in the same manner as management.

Free Cash Flow represents net cash provided by (used in) operating activities less purchases of property and equipment. We believe that Free Cash Flow is useful to investors as a liquidity measure because it measures our ability to generate or use cash. Once our business needs and obligations are met, cash can be used to maintain a strong balance sheet and invest in future growth. Additionally, we believe that Free Cash Flow is an important measure since we use third-party infrastructure partners to host our services and therefore we do not incur significant capital expenditures to support revenue generating activities.

Non-GAAP gross profit is defined as gross profit excluding stock-based compensation and related taxes, depreciation, and amortization expenses. Non-GAAP gross margin is defined as non-GAAP gross profit divided by revenue. We believe that these non-GAAP financial measures are useful to investors as they exclude expenses that are not reflective of our operational performance during the period and could mask underlying trends in our business.

Non-GAAP operating expenses represents operating expenses excluding stock-based compensation and related taxes, depreciation and amortization, and certain other non-recurring or non-cash items impacting operating expenses that we do not consider indicative of our ongoing business performance. Non-GAAP research and development expense, non-GAAP sales and marketing expense, and non-GAAP general and administrative expense represent their respective operating expense line items excluding stock-based compensation and related taxes, depreciation, amortization, and certain other non-recurring or non-cash items. Similar to non-GAAP gross profit and non-GAAP gross margin, we consider non-GAAP operating expense, non-GAAP research and development expense, non-GAAP sales and marketing expense, and non-GAAP general and administrative expense to be useful measures as they exclude expenses that are not reflective of our operational performance and could mask underlying trends in our business.

Dear fellow shareholders, 3 Q1 2024 • Letter to Shareholders We believe that great companies are built in the public markets, and we are proud to have made the transition this quarter. Our IPO was an important moment for the company. I want to say thank you to our employees, users, and investors who all made it possible. I also want to say welcome to our new investors, particularly to our new user-investors. For users to be able to own some of Reddit has long been a dream of mine. It’s an exciting time. Reddit is one of the largest places for authentic human connection and conversation online, and we are seeing more and more people discover and appreciate this. We believe Reddit is more important than ever before, both as an alternative to traditional social media, and as we enter the AI era. People need a place where they can truly be themselves, and as more content on the internet is written by machines, Reddit is a source for authentic conversation, unique perspectives, earnest advice, honest reviews, and answers to questions about every topic imaginable. We are happy with our progress this quarter. We grew users across the platform, including logged-in and logged-out and the U.S. and abroad. We were cash flow positive and had our first profitable Q1 on an Adjusted EBITDA basis, which as an ads business is typically our smallest quarter from a revenue standpoint. Our management target is to grow revenue twice as fast as total adjusted costs, but this quarter we grew revenue five times faster. The most reliable way to grow is to make Reddit better. As such, our primary focus this year is to continue to make Reddit faster, safer, and easier to use. It sounds simple, but the details matter. Anyone who has used Reddit has encountered rough edges that we aim to smooth. We believe our investments in ML and AI will continue to improve relevance, engagement, and moderation. When we say relevance, we are referring to our ability to help users find communities they will love, which in turn increases engagement across the platform. For moderation, our testing of large language models has dramatically reduced the time required for communities to enforce their own rules. We are also using machine translation to unlock our mostly-English language corpus for the rest of the world. We believe this will drive growth in the near term, and over time will also allow users from all over the world to connect regardless of the languages they speak.

As we look to the future, we see huge opportunities for on-platform search and our user economy. Historically, the value of Reddit to our users has been in conversation about recent topics, but with improvements to search, we can unlock the huge amount of latent value in past content, including questions, reviews, and advice that we have. The user economy refers to a family of features that includes both our developer platform, which enables third-party developers to expand what the Reddit platform can be used for, and monetization primitives that can unlock the entrepreneurial energy we see across Reddit today. Overall, this was a strong start to the year for Reddit and we are executing better than ever. We see so much opportunity, and could not be more excited about our future.

User & product highlights International growth & machine translation International growth remains a top priority and we are seeing progress with our playbook to localize the user experience In Q1, we launched machine translation in select languages, beginning in French, with additional languages on our roadmap Machine translation is a multi-phase strategy where we first translate the highest quality posts to drive top-of-funnel traffic and then scale to an immersive experience to break the language barrier on Reddit over time 5 In Q1, we saw record traffic with quarterly average DAUq of 82.7 million and over 37% year-over-year growth We saw growth across the platform as U.S. DAUq grew 45% and International DAUq grew 30% year-over-year We saw strong growth in both Logged-in and Logged-out Users, growing 27% and 48% year-over-year, respectively Weekly Active Uniques (“WAUq”) averaged 306.2 million in the first quarter of 2024, an all-time high and an increase of 40% year- over-year Structural user growth is driven by our work on the product and our investments in machine learning and search to personalize and improve the experience for users Quarterly results Q1 2024 • Letter to Shareholders 37% Y/Y 41.5 Q1 ‘23 Q2 ‘23 Q4 ‘23Q3 ‘23 Q1 ‘24 (IN MILLIONS)US DAUq Int’l DAUq 28.6 28.7 32.0 36.4 41.2 31.7 31.7 34.0 36.7 82.7 60.3 60.4 66.0 73.1 Q1 ‘24 DAUq 82.7M Machine translation

6 We are using AI to assist in moderation and reduce friction with creating content and contributing on the platform This builds on the work we did last year to deliver a suite of new moderator products and enhancements for our more than 60,000 daily active moderators We launched a post guidance tool in one of Reddit’s largest communities, r/askreddit with 46M members, to help users in real-time with composing a post that fits the communities’ rules, driving more efficient contribution and less manual moderation The post guidance tool reduced content that would have been removed by a human moderator by 20% and increased users’ posts attempts, based on tests run in r/askreddit between December 2023 and January 2024 Making it easier to moderate allows our moderators to focus on leading and growing their communities Product spotlight: AI moderation & post guidance Post guidance Q1 2024 • Letter to Shareholders User & product highlights

7 Total revenue in Q1 grew 48% year-over-year to $243.0 million, the fastest year-over-year growth since Q1'22 and the third consecutive quarter of accelerating revenue growth Advertising revenue grew 39% year-over-year, and other revenue of $20.3M increased over 450% year-over-year, primarily driven by new data licensing agreements signed in the first quarter U.S. revenue grew 53% year-over-year and International revenue grew 30% year-over-year. International revenue represented 18% of total revenue in the first quarter Advertising Revenue growth was primarily driven by increases in impressions delivered as we continued to attract new users and deepen engagement on the platform, which offset a year- over-year decline in advertising pricing Our full suite of solutions across the marketing funnel continued to position us well for a broad set of advertisers.

Advertising & monetization highlights Free-form ads are a Reddit unique ad format for advertisers to create long-form multimedia content, including images, videos, and text Users come to Reddit to be informed and this format enables advertisers to contribute their voice and expertise to communities that are relevant for their category In internal tests, free-form ads are outperforming other ad types in average click-through-rates by 28% Just Eat Takeaway, a mid-sized EMEA- based advertiser that connects customers with restaurants for delivery, utilized free- form ads as a strategy to drive brand awareness and engagement on Reddit Just Eat Takeaway targeted a variety of interests and communities related to Healthy Living and Food & Drink, and asked Redditors to upvote their favorite veggie meal The campaign drove a 10pt lift in ad awareness, the highest increase across all other formats in their campaign To help businesses understand how their brand or category is discussed on Reddit, we launched Reddit Pro, a free suite of social listening and engagement tools, in March.

Revenue Total revenue was $243.0 million, an increase of 48% from $163.7 million in the first quarter of 2023, primarily driven by an increase in impressions, partially offset by a decrease in ad pricing. In addition, other revenues increased as a result of data licensing agreements executed in 2024. ARPU ARPU was $2.94, an increase of 8% from $2.72 in the first quarter of 2023. Cost of Revenue Cost of revenue was $27.6 million, an increase of 3% from $26.9 million in the first quarter of 2023, primarily driven by increased hosting usage to support user growth on our platform and an increase in advertising measurement and other services, partially offset by hosting cost efficiencies and lower hosting prices. Gross Profit and Non-GAAP Gross Profit Gross profit was $215.3 million, or a gross margin of 88.6%, as compared to $136.9 million, or a gross margin of 83.6%, in the first quarter of 2023.

Operating Expenses and Non-GAAP Operating Expenses Total operating expense was $804.6 million, as compared to $207.5 million, in the first quarter of 2023. The increase in total operating expenses in the first quarter of 2024 was primarily driven by an increase in stock-based compensation expense and related taxes as a result of the IPO. Total stock-based compensation expense and related taxes was $595.5 million, as compared to $13.2 million in the first quarter of 2023. Non-GAAP operating expense⁴ (which excludes stock-based compensation and related taxes, depreciation, amortization, and restructuring expenses) was $205.6 million, as compared to $187.2 million, in the first quarter of 2023. Non-GAAP operating expenses growth slowed starting in the three months ended March 31, 2023, as a result of operating efficiencies put into place throughout 2023. Net Loss and Adjusted EBITDA Net loss was $575.1 million, an increase from a net loss of $60.9 million in the first quarter of 2023. The increase in net loss was primarily driven by an increase in stock-based compensation expense and related taxes as a result of the IPO. Adjusted EBITDA¹ was $10.0 million as compared to $(50.2) million in the first quarter of 2023. The increase in Adjusted EBITDA over the prior year was primarily driven by an increase in revenue and slowing cost growth as the result of operating efficiencies. Cash Flow and Capital Expenditures Net cash provided by operating activities was $32.1 million, an increase from $4.1 million in the first quarter of 2023. Free Cash Flow² was $29.2 million, an increase from $3.7 million in the first quarter of 2023. Capital expenditures were $2.9 million in the first quarter or about 1% of revenue. Balance Sheet and Share Count Cash, cash equivalents, and marketable securities were $1.67 billion and $1.21 billion as of March 31, 2024 and December 31, 2023, respectively.

Forward Looking Statements This letter contains forward-looking statements within the meaning of the Securities Act of 1933, as amended, the Securities Exchange Act of 1934, as amended, and the Private Securities Litigation Reform Act of 1995. Forward-looking statements generally relate to future events or Reddit's future financial or operating performance. In some cases, you can identify forward-looking statements because they contain words such as "may," "will," "should," "expects," "plans," "anticipates," "going to," "could," "intends," "target," "projects," "contemplates," "believes," "estimates," "predicts," "potential" or "continue" or the negative of these words or other similar terms or expressions that concern Reddit's expectations, strategy, priorities, plans or intentions. Forward-looking statements in this release include, but are not limited to, statements regarding Reddit’s priorities, future financial and operating performance, including headcount strategy, breakeven performance objective, capitalization of training data, evolution of AI, international growth strategies to increase content consumption and improve local user experience, consumer product strategy with respect to growth and engagement, GAAP and non-GAAP guidance, strategies, and expectations of growth. Reddit's expectations and beliefs regarding these matters may not materialize, and actual results in future periods are subject to risks and uncertainties that could cause actual results to differ materially from those projected, including those more fully described under the caption “Risk Q1 2024 • Letter to Shareholders

Factors” and elsewhere in documents that Reddit files with the Securities and Exchange Commission (the “SEC”) from time to time, including Reddit’s Quarterly Report on Form 10-Q for the quarter ended March 31, 2024, which is being filed with the SEC at or around the date hereof. The forward-looking statements in this release are based on information available to Reddit as of the date hereof, and Reddit undertakes no obligation to update any forward-looking statements, except as required by law. A Note About Metrics We define a daily active unique (“DAUq”) as a user whom we can identify with a unique identifier who has visited a page on the Reddit website, www.reddit.com, or opened a Reddit application at least once during a 24-hour period. Average DAUq for a particular period is calculated by adding the number of DAUq on each day of that period and dividing that sum by the number of days in that period. We define a weekly active unique (“WAUq”) as a user whom we can identify with a unique identifier who has visited a page on the Reddit website, www.reddit.com, or opened a Reddit application at least once during a trailing seven-day period. Average quarterly WAUq for a particular period is calculated by adding the number of WAUq on each day of that period and dividing that sum by the number of days in that period. We define average revenue per unique (“ARPU”) as quarterly revenue in a given geography divided by the average DAUq in that geography. For the purposes of calculating ARPU, advertising revenue in a given geography is based on the geographic location in which advertising impressions are delivered, as this approximates revenue based on user activity, while other revenue in a given geography is based on the billing address of the customer. Use of Non-GAAP Financial Measures We use certain non-GAAP financial measures to supplement our consolidated financial statements, which are presented in accordance with U.S. GAAP, to evaluate our core operating performance. These non- GAAP financial measures include Adjusted EBITDA, Free Cash Flow, non-GAAP gross profit, non-GAAP gross margin, non-GAAP operating expense, non-GAAP research and development expense, non-GAAP sales and marketing expense, and non-GAAP general and administrative expense. We use these non- GAAP financial measures to facilitate reviews of our operational performance and as a basis for strategic planning. By excluding certain items that are non-recurring or not reflective of the performance of our normal course of business, we believe that these non-GAAP financial measures provide meaningful supplemental information regarding our performance. Accordingly, we believe these non-GAAP financial measures are useful to investors and others because they allow investors to supplement their understanding of our financial trends and evaluate our ongoing and future performance in the same manner as management. However, there are a number of limitations related to the use of non-GAAP financial measures as they reflect the exercise of judgment by our management about which expenses are excluded or included in determining these non-GAAP measures. These non-GAAP measures should be considered in addition to, not as a substitute for or in isolation from, our financial results prepared in accordance with U.S. GAAP. Other companies, including companies in our industry, may calculate these non-GAAP financial measures differently or not at all, which reduces their usefulness as comparative measures. A reconciliation is provided in the Appendix for each historical non-GAAP financial measure to the most directly comparable financial measure stated in accordance with U.S. GAAP. Reddit encourages investors 14 Q1 2024 • Letter to Shareholders

15 to review the related U.S. GAAP financial measures and the reconciliation of these non-GAAP financial measures to their most directly comparable U.S. GAAP financial measures, and not to rely on any single financial measure to evaluate Reddit’s business. Adjusted EBITDA is defined as net income (loss) excluding interest (income) expense, net, income tax expense (benefit), depreciation and amortization, stock-based compensation expense and related taxes, other (income) expense, net, and certain other non-recurring or non-cash items impacting net income (loss) that we do not consider indicative of our ongoing business performance. Other (income) expense, net consists primarily of realized gains and losses on sales of marketable securities, foreign currency transaction gains and losses, and other income and expense that are not indicative of our core operating performance. We consider the exclusion of certain non-recurring or non-cash items in calculating Adjusted EBITDA to provide a useful measure for investors and others to evaluate our operating results in the same manner as management. Free Cash Flow represents net cash provided by (used in) operating activities less purchases of property and equipment. We believe that Free Cash Flow is useful to investors as a liquidity measure because it measures our ability to generate or use cash. Once our business needs and obligations are met, cash can be used to maintain a strong balance sheet and invest in future growth. Additionally, we believe that Free Cash Flow is an important measure since we use third-party infrastructure partners to host our services and therefore we do not incur significant capital expenditures to support revenue generating activities. Non-GAAP gross profit is defined as gross profit excluding stock-based compensation and related taxes, depreciation, and amortization expenses. Non-GAAP gross margin is defined as non-GAAP gross profit divided by revenue. We believe that these non-GAAP financial measures are useful to investors as they exclude expenses that are not reflective of our operational performance during the period and could mask underlying trends in our business. Non-GAAP operating expenses represents operating expenses excluding stock-based compensation and related taxes, depreciation and amortization, and certain other non-recurring or non-cash items impacting operating expenses that we do not consider indicative of our ongoing business performance. Non-GAAP research and development expense, non-GAAP sales and marketing expense, and non- GAAP general and administrative expense represent their respective operating expense line items excluding stock-based compensation and related taxes, depreciation, amortization, and certain other non-recurring or non-cash items. Similar to non-GAAP gross profit and non-GAAP gross margin, we consider non-GAAP operating expense, non-GAAP research and development expense, non-GAAP sales and marketing expense, and non-GAAP general and administrative expense to be useful measures as they exclude expenses that are not reflective of our operational performance and could mask underlying trends in our business.
