Dear Shareholders, This is my first letter to you as CEO of Instacart — and I couldn’t be more energized about where we’re headed. Over the past six years, I’ve had the privilege of helping build many of the capabilities and partnerships that make Instacart distinct. We’re so much more than a marketplace. Instacart is the leading technology and enablement partner for the grocery industry — helping consumers save time, retailers run their businesses, and brands connect with customers. In a trillion-dollar industry ripe for innovation – we power how groceries get discovered, bought, and delivered — and we’re just getting started. Our foundation is strong, our momentum is growing, and I’m confident we have all the right ingredients to accelerate into our next chapter. In Q3, we delivered another strong quarter: orders grew 14% year-over-year, GTV increased 10%, and both net income and Adjusted EBITDA expanded. Our strategy to accelerate online grocery adoption is working. We’re deepening customer and retailer relationships, expanding our ads ecosystem, and launching innovative AI-powered tools across all aspects of our business — all while driving profitable growth. Winning in grocery means nailing the fundamentals — selection, quality, convenience, and affordability. Fresh food is the hardest part of online grocery, and it’s where Instacart shines. Our deep retailer network, data from over 1.5 billion lifetime orders, and our experienced shopper network ensures we deliver the same freshness and care customers expect from the grocers they’ve trusted for generations. And we deliver fast. 75% of our delivery orders are on demand meaning they are on median delivered in 90 minutes or less, and approximately 25% of typical priority orders are delivered in less than 30 minutes. That combination of selection, quality, speed, and reliability builds trust — and when customers trust us with their perishables, they shop more often, spend more per order, and stay longer. Affordability is key to accelerating online grocery adoption. We’re helping retailers see how offering the same prices online and in-store drives both growth and loyalty. The results are clear: over the past year, retailers offering same-as-in-store pricing have on average grown more than 10 percentage points faster than those that haven’t — and they retain customers better on our platform. In recent months, more retailers are taking action. Pattison Food Group banners – including Buy Low Foods, Nesters Market, and Save-on-Foods – are now live on our marketplace at price parity, along with Best Buy and regional grocers like Choices Market and Jerry’s. Several national and regional grocers have also launched price parity pilots in markets including Chicago, Dallas, Nashville, Tampa, and Tucson. And we’re making these savings easier for customers to find — through improved merchandising and tools like Flyers and Loyalty that help retailers deliver even more value directly to customers. We’re also extending the power of our marketplace to retailers through our enterprise solutions — taking what we’ve built and putting it directly in their hands, at a scale no one else can match. Our enterprise offerings — including Storefront technologies, Fulfillment Services, Carrot Ads, Caper Carts, FoodStorm, Carrot Tags, and more — help retailers compete and grow online and in-store. And because we’re not a retailer ourselves, our success is fully aligned with theirs. When our partners grow, we grow. ​ ​ ​ ​ 1

That alignment is paying off. Our Storefront technologies now power more than 350 grocers’ e-commerce sites – and it’s built to scale, as we expand into new categories and regions. We recently launched Storefront Pro with Cub Grocery & Liquor, a leading Midwest grocer, and signed a new partnership with Merchants Distributors, who collectively represents hundreds of local independent grocers. We also rolled out Storefront Pro for Restaurant Depot, one of the biggest wholesalers serving independent restaurants, and introduced Instacart Business features within Storefront and Storefront Pro to help grocers manage complex ordering needs. We also see an exciting international opportunity ahead. Building on our acquisition of Wynshop – which powers storefronts for retailers in Europe and Australia – we’re seeing strong demand and clear product-market fit for our technologies abroad. AI is the newest pillar of our enterprise offerings – and we’re introducing Instacart’s AI solutions at the exact moment retailers need us most. As AI transforms how people shop for groceries and feed their families, our tools bring powerful, practical capabilities to help grocers compete and win — from personalized shopping assistants and smarter catalog insights to real-time shelf intelligence and instant, self-serve analytics. Built for the complexity of grocery and powered by our unique insights, Instacart’s AI Solutions deliver more personalized, connected, and efficient shopping experiences — online and in-stores. We’re partnering with leading retailers like Good Food Holdings, Kroger, McKeever’s, and Sprouts Farmers Market on these solutions and are excited to build on this momentum. Together, the combination of our marketplace scale and enterprise platform make our business stronger and more resilient. Even when retailers participate on other marketplaces, the depth of our integrations and the differentiated value of our enterprise solutions empower us to achieve consistent double-digit annual GTV growth with those retailers on average1. We expect Kroger will be another example of this, especially as they just doubled down on Instacart as their primary delivery fulfillment partner across all Kroger digital properties. Today, more than 80% of our GTV comes from non-exclusive retailers, and among the exclusive GTV that remains, the majority is with retailers who partner with us on at least one enterprise solution. ​ 1 Includes total GTV from both marketplace and enterprise for Instacart's top enterprise retailers that have launched on other marketplace(s) for at least one year. Average line represents the linear regression line of best fit. ​ ​ ​ ​ 2

We’re also expanding and strengthening our ads ecosystem — extending our reach across online, off-platform, and in-store channels for more than 7,500 brand partners. Beyond our leading marketplace, which spans more than 1,800 retail banners, we work with over 240 Carrot Ads partners – and that number keeps growing. Nearly all of our new Storefront Pro launches now include Carrot Ads, including recent additions like Cub Grocery & Liquor and Restaurant Depot. We’ve also signed new third-party partners like Bottlecapps and Vroom Delivery, launched Carrot Ads with Hy-Vee RedMedia to power ads on Hy-Vee.com, and deepened our relationships with existing partners such as Uber Eats, where we recently launched Shoppable Display ads on its U.S. grocery and retail marketplace. Together, these integrations showcase the strength of our technology, the depth of advertiser demand, and add more revenue opportunities over time. We’re also bringing our advertiser network into stores. We recently launched Caper Ads with Wakefern, where our AI-powered smart carts will soon be deployed across nearly 20% of Wakefern’s cooperative member stores. And we’re proud to be TikTok’s first end-to-end retail media network partner — opening a new channel for CPGs to use our first-party retail media data to reach highly engaged audiences. Underpinning all of this is AI — which is helping us build smarter products, better tools, and more accurate measurement across our ads ecosystem. In Q3, we enhanced our ad relevance system with large language models — driving stronger engagement and more items added to carts via our Sponsored Product units. We've also scaled our one-click, AI-powered recommendations to approximately 3,000 brands, making it easier for them to optimize bids, budgets, and creativity. And now, our AI-generated landing pages are available to all brands, enabling rapid creation of dynamic, high-performing content for both on-platform and off-platform campaigns. Across our marketplace, enterprise solutions, and ads ecosystem – Instacart is executing from a position of strength. We’re the clear leader in online grocery among digital-first players, one of the top retail media networks in North America, and we operate a profitable, cash-generating model that gives us the flexibility to keep investing in what’s next. Our scale, density, and operational discipline continue to unlock efficiencies that fuel innovation and growth across our platform. And we’re focused on accelerating – bringing more customers online, deepening our partnerships with retailers and brands, and building the technologies that will power the future of grocery. To underscore our confidence in long-term value creation, we authorized a $1.5 billion increase to our share repurchase program and plan to enter into a $250 million accelerated share repurchase program, while continuing to opportunistically repurchase shares.​ Chris Rogers Chief Executive Officer ​ ​ ​ ​ 3

Q3’25 Financial Update Q3'25 Financial Highlights ●​ Orders of 83.4 million, up 14% year-over-year. ●​ GTV of $9,170 million, up 10% year-over-year. ●​ Total revenue of $939 million, up 10% year-over-year, representing 10.2% of GTV. ●​ Transaction revenue of $670 million, up 10% year-over-year, representing 7.3% of GTV. ●​ Advertising & other revenue of $269 million, up 10% year-over-year, representing 2.9% of GTV. ●​ GAAP gross profit of $692 million, up 8% year-over-year, representing 7.5% of GTV and 74% of total revenue. ●​ GAAP net income of $144 million, up 22% year-over-year, representing 1.6% of GTV and 15% of total revenue. ●​ Adjusted EBITDA of $278 million, up 22% year-over-year, representing 3.0% of GTV and 30% of total revenue. Orders were 83.4 million, up 14% year-over-year, driving GTV of $9,170 million, up 10% year-over-year. As we expected, average order value decreased 4% year-over-year, driven by restaurant orders and lowered basket minimums to $10 for Instacart+ members to get waived delivery fees. Total revenue was $939 million, up 10% year-over-year, primarily driven by GTV growth. ​ ​ ​ ​ 8

Transaction revenue was $670 million, up 10% year-over-year, representing 7.3% of GTV. Transaction revenue as a percent of GTV was flat on a year-over-year basis, as our ongoing investments in affordability initiatives designed to increase customer engagement were largely offset by lower consumer incentives and increased fulfillment efficiencies. ​ ​ Advertising & other revenue was $269 million, up 10% year-over-year. This performance was in-line with our expectations and reflects the ongoing resiliency and diversification of our ads platform. Advertising & other investment rate of 2.9% was effectively flat year-over-year. GAAP gross profit was $692 million, up 8% year-over-year, representing 7.5% of GTV and 74% of total revenue compared to 7.7% of GTV and 75% of total revenue in Q3’24. The year-over-year decrease in GAAP gross profit as a percent of GTV and as a percent of revenue was primarily driven by an increase in cost of revenue. ​ ​ ​ ​ 9

GAAP total operating expenses were $525 million, representing 5.7% of GTV compared to 6.1% of GTV in Q3'24. The year-over-year decrease in GAAP total operating expenses as a percent of GTV was primarily due to a decrease in paid marketing, which was elevated in the prior year quarter as we leaned into seasonal events. Adjusted total operating expenses, which exclude the impact of stock-based compensation expense and certain other expenses, were $436 million and represented 4.8% of GTV compared to 5.1% of GTV in Q3'24. The year-over-year improvement was primarily driven by a decrease in paid marketing for the reasons described above. GAAP net income was $144 million, up 22% year-over-year, representing 1.6% of GTV and 15% of total revenue. The year-over-year increase was primarily driven by growth in GAAP gross profit as described above. Adjusted EBITDA was $278 million, up 22% year-over-year, representing 3.0% of GTV and 30% of total revenue. The year-over-year increase was driven by a combination of GTV growth and operating leverage. We also generated operating cash flow of $287 million, an increase of $102 million year-over-year, primarily driven by strong operational performance. ​ ​ ​ ​ 10

Q4’25 Financial Outlook GTV $9,450 - $9,600 million Adjusted EBITDA $285 - $295 million ​ This GTV outlook represents year-over-year growth between 9% to 11%, with orders growth expected to outpace GTV growth. It reflects our strong performance in October, continued momentum from landing and expanding our enterprise partnerships, and is partially offset by the expected impact of EBT SNAP funding scenarios on our business. We have not provided the forward-looking GAAP equivalent to our adjusted EBITDA or a GAAP reconciliation as a result of the uncertainty regarding, and the potential variability of, reconciling items such as stock-based compensation and related payroll tax expenses, certain legal and regulatory accruals and settlements, and reserves for sales and other indirect taxes. Accordingly, a reconciliation of this non-GAAP guidance metric to its corresponding GAAP equivalent is not available without unreasonable effort. However, it is important to note that these reconciling items could have a significant effect on future GAAP results.​ Live Conference Call Instacart management will host a conference call to discuss the company's results at 5:00 a.m. Pacific Time (8:00 a.m. Eastern Time) on Monday, November 10. To access a live webcast of the conference call, please visit our Investor Relations website at https://investors.instacart.com.

You should not rely on forward-looking statements as predictions of future events. We have based the forward-looking statements contained in this letter and the accompanying oral presentation primarily on information available to us as of the date of this letter and the accompanying oral presentation and our current expectations and projections about future events and trends that we believe may affect our business, financial condition, and results of operations. While we believe such information provides a reasonable basis for these statements, such information may be limited or incomplete. Our statements should not be read to indicate that we have conducted an exhaustive inquiry into, or review of, all relevant information. These statements are inherently uncertain, and investors are cautioned not to unduly rely on these statements. Moreover, we operate in a very competitive and rapidly changing environment, and new risks may emerge from time to time. It is not possible for us 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 or outcomes to differ materially from those contained in any forward-looking statements we may make. Except as required by law, we undertake no obligation, and do not intend, to update these forward-looking statements. Key Business Metrics We use the following key business metrics to help us evaluate our business, identify trends affecting our performance, formulate business plans, and make strategic decisions. •​ Gross Transaction Value (GTV): We define GTV as the value of the products sold through Instacart, including applicable taxes, deposits and other local fees, customer tips, which go directly to shoppers, customer fees, which include flat subscription fees related to Instacart+ that are charged monthly or annually, and other fees. GTV consists of orders including those completed through Instacart Marketplace or services that are part of the Instacart Enterprise Platform. We believe that GTV indicates the health of our business, including our ability to drive revenue and profits, and the value we provide to our constituents. •​ Orders: We define an order as a completed customer transaction to purchase goods for delivery or pickup primarily from a single retailer through Instacart during the period indicated, including those completed through Instacart Marketplace or services that are part of the Instacart Enterprise Platform. We believe that orders are an indicator of the scale and growth of our business as well as the value we bring to our constituents. Non-GAAP Financial Measures We use the following non-GAAP financial measures in conjunction with GAAP measures to assess performance, to inform the preparation of our annual operating budget and quarterly forecasts, to evaluate the effectiveness of our business strategies, and to discuss our business and financial performance with our board of directors. We believe that these non-GAAP financial measures provide useful information to investors about our business and financial performance, enhance their overall understanding of our past performance and future prospects, and allow for greater transparency with respect to metrics used by our management in their financial and operational decision making. We are presenting these non-GAAP financial measures to assist investors in seeing our business and ​ ​ ​ ​ 13

financial performance through the eyes of management, and because we believe that these non-GAAP financial measures provide an additional tool for investors to use in comparing results of operations of our business over multiple periods with other companies in our industry. Adjusted EBITDA, Adjusted EBITDA as a Percent of GTV, and Adjusted EBITDA Margin. We define adjusted EBITDA as net income, adjusted to exclude (i) provision for income taxes, (ii) interest income, (iii) other (income) expense, net, (iv) depreciation and amortization expense, (v) stock-based compensation expense, (vi) payroll taxes related to stock-based compensation, (vii) certain legal and regulatory accruals and settlements, net, (viii) reserves for sales and other indirect taxes, net, and (ix) acquisition-related expenses. We define adjusted EBITDA margin as adjusted EBITDA as a percent of total revenue. We use adjusted EBITDA, adjusted EBITDA as a percent of GTV, and adjusted EBITDA margin because they are important measures upon which our management assesses our operating performance and the operating leverage in our business. Because adjusted EBITDA, adjusted EBITDA as a percent of GTV, and adjusted EBITDA margin facilitate internal comparisons of our historical operating performance, including as an indication of our total revenue growth and operating efficiencies when compared to GTV and total revenue over time, we use them to evaluate the effectiveness of our strategic initiatives and for business planning purposes. We also believe that adjusted EBITDA, adjusted EBITDA as a percent of GTV, and adjusted EBITDA margin, when taken collectively, may be useful to investors because they provide consistency and comparability with past financial performance, so that investors can evaluate our operating efficiencies by excluding certain items that may not be indicative of our business, results of operations, or outlook. In addition, we believe adjusted EBITDA is widely used by investors, securities analysts, rating agencies, and other parties in evaluating companies in our industry as a measure of operational performance. Adjusted EBITDA, adjusted EBITDA as a percent of GTV, and adjusted EBITDA margin should not be considered as alternatives to net income, net income as a percent of GTV, net income as a percent of total revenue, or any other measure of financial performance calculated and presented in accordance with GAAP. There are a number of limitations related to the use of adjusted EBITDA, adjusted EBITDA as a percent of GTV, and adjusted EBITDA margin rather than net income, net income as a percent of GTV, and net income as a percent of total revenue, which are the most directly comparable GAAP measures. Some of these limitations are that each of adjusted EBITDA, adjusted EBITDA as a percent of GTV, and adjusted EBITDA margin: ●​ excludes stock-based compensation expense; ●​ excludes payroll taxes related to stock-based compensation; ●​ excludes depreciation and amortization expense, and although these are non-cash expenses the assets being depreciated may have to be replaced in the future, increasing our cash requirements; ●​ excludes acquisition-related expenses; ●​ does not reflect the positive or adverse adjustments related to the reserve for sales and other indirect taxes or certain legal regulatory accruals and settlements; ●​ does not reflect interest income which increases cash available to us; ●​ does not reflect other income or expense that includes unrealized and realized gains and losses on foreign currency exchange; and ●​ does not reflect provision for or benefit from income taxes that reduces or increases cash available to us. ​ ​ ​ ​ 14

Adjusted Cost of Revenue and Adjusted Cost of Revenue as a Percent of GTV. We define adjusted cost of revenue as cost of revenue excluding depreciation and amortization expense and stock-based compensation expense. Adjusted Operations and Support Expense and Adjusted Operations and Support Expense as a Percent of GTV. We define adjusted operations and support expense as operations and support expense excluding depreciation and amortization expense, stock-based compensation expense, and payroll taxes related to stock-based compensation. Adjusted Research and Development Expense and Adjusted Research and Development Expense as a Percent of GTV. We define adjusted research and development expense as research and development expense excluding depreciation and amortization expense, stock-based compensation expense, and payroll taxes related to stock-based compensation. Adjusted Sales and Marketing Expense and Adjusted Sales and Marketing Expense as a Percent of GTV. We define adjusted sales and marketing expense as sales and marketing expense excluding depreciation and amortization expense, stock-based compensation expense, and payroll taxes related to stock-based compensation. Adjusted General and Administrative Expense and Adjusted General and Administrative Expense as a Percent of GTV. We define adjusted general and administrative expense as general and administrative expense excluding depreciation and amortization expense; stock-based compensation expense; payroll taxes related to stock-based compensation; certain legal and regulatory accruals and settlements, net; reserves for sales and other indirect taxes, net; and acquisition-related expenses. Adjusted Total Operating Expenses and Adjusted Total Operating Expenses as a Percent of GTV. We define adjusted total operating expenses as the sum of adjusted operations and support expense, adjusted research and development expense, adjusted sales and marketing expense, and adjusted general and administrative expense. We exclude depreciation and amortization expense and stock-based compensation expense from our non-GAAP financial measures as these are non-cash in nature. We exclude payroll taxes related to the vesting and settlement of certain equity awards; certain legal and regulatory accruals and settlements, net; reserves for sales and other indirect taxes, net; and acquisition-related expenses as these are not indicative of our operating performance. Non-GAAP financial measures are not meant to be considered in isolation or as a substitute for comparable GAAP financial measures and should be read only in conjunction with our condensed consolidated financial statements prepared in accordance with GAAP. Our presentation of non-GAAP financial measures may not be comparable to similar measures used by other companies, which reduce their usefulness as comparative measures. In addition, other companies may not publish these or similar measures. Further, these measures have certain limitations in that they do not include the impact of certain expenses that are reflected in our consolidated statements of operations. We encourage investors and others to review our business, results of operations, and financial information in their entirety, not to rely on any single financial measure, and carefully consider our results under GAAP, as well as our supplemental non-GAAP information and the reconciliation between these presentations, to more fully understand our business.
