Dear fellow shareholders, It’s been another strong quarter for Reddit, with particularly strong performance on the revenue and profitability lines, and I’m proud of how the company is executing as we move into the second half of 2025. A personal highlight for me was meeting with advertisers in Cannes earlier this summer. That trip was a good barometer for how brands view Reddit today: they want to work with us, they understand our distinct role on the internet, and they recognize we deliver real value to their businesses. During a demo of Reddit Insights, our new AI- powered brand insights product, a client remarked, “This will be our Super Bowl ad next year.” Ok, on to the numbers: Revenue grew 78% year-over-year to $500 million—our fastest quarterly growth rate since 2022. Daily active users grew to 110 million, up 21% year-over-year, with growth in both the U.S. and international markets. This was driven mainly by product improvements and increased marketing activity. And this was our most profitable quarter yet. These results are a testament to our work, our users, and the power of Reddit’s communities. We’ll get to Q2 shortly, but what excites me most is what’s ahead. The world and the internet are rapidly changing, and I believe Reddit has a once-in-a-generation opportunity. For people, conversation and connection are becoming more valuable and rare. In a world increasingly dominated by algorithms and automation, the need for human voices has never been greater. We see this every day as nearly 50 million scrollers come to Reddit for their favorite communities, and 60 million seekers land on Reddit in search of better answers to their questions. In fact, ~80% of users in a recent survey¹ said they believe some questions can only be answered by humans, as opposed to AI-generated summaries. For LLMs and AI search engines, these conversations and the knowledge they create are essential for training. Platforms like Reddit, where people discuss every aspect of life—from the trivial to the transformative—are the backbone of building AI that actually works. That’s why Reddit is the #1 most cited domain for AI across all models, per data collected by Profound. In an automated world that depends on human knowledge, we view Reddit as one of the most important and differentiated data sources. We believe this validates what we’ve always thought: human conversation is not being replaced by AI; instead, it’s becoming more important. AI doesn’t invent knowledge—it learns from us. From real people, sharing real perspectives. You can’t have artificial intelligence without actual intelligence. And for brands, Reddit’s authenticity creates something rare: a direct connection with people when they’re seeking trustworthy opinions. As more of the content you see online is synthesized, summarized, and sanitized by AI, Reddit stands out for its honesty and subjectivity. For many questions, there isn’t a single objective answer; people want multiple viewpoints and lived experiences. This is why Reddit is synonymous with product and service recommendations—people turn to Reddit when they want to make informed decisions fast. 3 Q2 2025 • Letter to Shareholders ¹Source: Reddit Custom Survey, n=2,340, June 2025 (US, UK, AUS, CA).

We see tremendous potential to grow our user base and deepen engagement, and we’re moving quickly to align priorities and resources to capture that opportunity. As a first step, we clarified our product strategy and are investing in making Reddit a better experience for everyone who comes to the platform—whether they’re scrolling their favorite subreddit, seeking input on a purchase, or discovering a new community for the first time. To focus on the areas that matter most, we are deprioritizing a few initiatives, including our work on the user economy. It’s still an opportunity we believe in, but we’re concentrating our resources on the areas that will drive results for our most pressing needs: improving the core product, making Reddit a go-to search engine, and expanding internationally. Here’s what we’re working on right now: Let’s start with the core product: First impressions matter, and we want to make your first moments on Reddit sticky and worth coming back for. We’re zeroing in on a few key areas: making onboarding even more intuitive and search- forward, lowering barriers to log in and contribute, and using AI to help people find their home, whether that’s through real-time personalization or smarter community discovery. We’re also moving fast on human verification to preserve Reddit’s authenticity—something our users have repeatedly asked for, and we’re eager to deliver on. Second, search: Reddit is one of the few platforms positioned to become a true search destination. We offer something special: a breadth of conversations and knowledge you can’t find anywhere else. Every week, hundreds of millions of people come to Reddit looking for advice, and we’re turning more of that intent into active users of Reddit’s native search. We’re seeing good traction here as our core search product now has 70 million weekly users and Reddit Answers has grown to 6 million, up from 1 million last quarter. Next, we’re expanding Reddit Answers globally, integrating it more deeply into the core search experience, and making search a central feature across Reddit. We’re pairing these product updates with marketing initiatives to increase awareness and adoption of Reddit Answers worldwide. And finally, international expansion: Machine translation is now live in 23 languages, unlocking Reddit for millions of people across Asia, Europe, and Latin America. This is just the start of a growth flywheel—translation and marketing bring people in, localized content and app experience deepen relevancy, and scaled moderator recruitment creates stronger ecosystems. Our goal is for Reddit to be self-sustaining in these countries, and the early results are promising. Recently, we celebrated Reddit’s 20th year, and I’ve never been more excited about our business and potential than I am today. The internet is evolving, and our role as a community-powered platform for human connection is only becoming more critical. This next chapter is ours to write—and we’re finishing the first pages already. As I’ve said before, we control our own destiny—and we’re focused on building Reddit into the most human, trusted place on the internet. Thank you to our team, the moderators, and users for helping make Reddit what it is today. Steve Huffman Co-Founder & Chief Executive Officer 4 Q2 2025 • Letter to Shareholders

Reddit communities: real, relevant, and essential In a rapidly changing internet, real human conversation is becoming more rare, but it’s still what people seek most when making decisions or trying to understand the world.

Therefore, a reconciliation of these non-GAAP guidance measures to their corresponding U.S. GAAP guidance measures is not available without unreasonable effort About Reddit Reddit is a community of communities.

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 letter include, but are not limited to, statements regarding Reddit’s priorities, future financial and operating performance, including evolution of machine translation, 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 SEC from time to time, including Reddit’s Quarterly Report on Form 10-Q for the quarter ended June 30, 2025, which is 12 Q2 2025 • Letter to Shareholders

being filed with the SEC at or around the date hereof. The forward-looking statements in this letter 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, Adjusted EBITDA margin, Free Cash Flow, Free Cash Flow margin, total adjusted costs and expenses, 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 included or excluded 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 below 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 13 Q2 2025 • Letter to Shareholders

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. Adjusted EBITDA margin is defined as Adjusted EBITDA divided by revenue. Incremental Adjusted EBITDA margin is defined as the change in Adjusted EBITDA divided by the change in revenue over the same period. We consider the exclusion of certain non-recurring or non- cash items in calculating Adjusted EBITDA and Adjusted EBITDA margin 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. Free Cash Flow margin is defined as Free Cash Flow divided by revenue. 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. Total adjusted costs and expenses represents cost of revenue and operating expenses excluding stock- based compensation and related taxes, depreciation and amortization, and certain other non-recurring or non-cash items impacting cost of revenue and operating expenses that we do not consider indicative of our ongoing business performance. 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 and amortization, and certain other non-recurring or non-cash items. We consider adjusted costs and expenses, 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.
