While we may elect to update such forward-looking statements at some point in the future, except as may be required by law, we disclaim any obligation to do so, even if subsequent events cause our views to change. Non-GAAP Financial Measures In addition to our results determined in accordance with generally accepted accounting principles in the United States (“GAAP”), we review financial measures that are not calculated and presented in accordance with GAAP (“non-GAAP financial measures”). We believe our non-GAAP financial measures are useful in evaluating our operating performance. We use the following non-GAAP financial information, collectively, to evaluate our ongoing operations and for internal planning and forecasting purposes. We believe that non-GAAP financial information, when taken collectively, may be helpful to investors, because it focuses on underlying operating results and trends, provides consistency and comparability with past financial performance, and assists in comparisons with other companies, some of which use similar non-GAAP financial information to supplement their GAAP results. The non-GAAP financial information is presented for supplemental informational purposes only, should not be considered a substitute for financial information presented in accordance with GAAP, and may be different from similarly titled non-GAAP measures used by other companies. A reconciliation of each historical non-GAAP financial measure to the most directly comparable financial measure stated in accordance with GAAP is provided above. Reconciliations of forward- looking non-GAAP financial measures are not provided because we are unable to provide such reconciliations without unreasonable effort due to the uncertainty regarding, and potential variability of, certain items, such as stock-based compensation expense and other costs and expenses that may be incurred in the future. Investors are encouraged to review the related GAAP financial measures and the reconciliation of these non-GAAP financial measures to their most directly comparable GAAP financial measures.

At Rivian, we are laying the foundations for a future that we believe will be fully electric, autonomous, and AI defined. The reviews for R2 affirm that our category-defining brand and vertically integrated and extensible technologies resonates deeply with consumers. Start of External R2 Deliveries Rivian began deliveries of R2 vehicles to external customers on June 9, 2026. We believe R2 will be a game changer for our customers and a driver of our company’s long-term growth and profitability. Commercial Van Momentum Amazon now has over 40,000 Rivian Electric Delivery Vans delivering packages across thousands of cities in North America. In addition to the EDV standard pack variant already on the road, we are developing new variants with a large battery pack and all-wheel drive (AWD) to support Amazon’s needs. Technology Roadmap In the not too distant future, we believe advanced assisted driving capabilities will be a key differentiator for customers and a driver of market share. Our assisted driving feature development for Autonomy+ is progressing well. We expect to begin rolling out point-to-point capabilities by the end of this year. We are encouraged with the take rates for our Autonomy+ offering. Quarterly Financial Highlights In the second quarter, Rivian generated $1.658 billion of revenue, a 27% increase over the same quarter last year driven by a 14% year-over-year increase in delivery volumes, $108 million in revenues related to regulatory credits, and strong performance from our software and services segment. Gross profit was $179 million. 4Q2 2026 Earnings Presentation © 2026 Rivian. All rights reserved. Start of R2 external customer deliveries and continued execution Q2 2026 Business Summary

All rights reserved. 6 “I've driven lots of electric SUVs in recent years, and the new R2 is the most compelling of the bunch.” “I had high expectations for R2, it totally blew me away.” “A muscular electric SUV that's legitimately capable off-road, but whose technology and sheer ingenuity feel a full generation ahead of anything from legacy automakers.” “The new Rivian R2 is a very composed, modern utility vehicle that’s as capable on and off the road as it is comfortable throughout. It’s also jam-packed with tech designed to enhance the driving experience while elevating the aspects of your life adjacent to driving.” “The new Rivian R2 is one of the best new cars I've driven in years…It's only June, but I can confidently call the R2 my best car of the year without much doubt. Only two new cars exist in the entire world right now that I might actually want: an unobtainium 992.2 Porsche GT3 Touring and now the almost bafflingly affordable Rivian R2.” “[R2 is] awesome. I want one. And I’ll buy one. I rate Rivian’s winsome, innovation-packed new terrain droid among the finest vehicle designs in the world, not least because it looks convincingly like an SUV.” More unfiltered R2 reviews are available at stories.rivian.com/r2-media-drive-impressions-utah-june-2026 Sign up for your R2 demo drive now at rivian.com/demo-drive

Continuous Software Improvement Rivian Assistant is now available to all R1 owners with plans to launch on R2 later this year Our relentless focus on vertical integration remains a core competitive differentiator, allowing us to seamlessly unify our hardware and software architecture to deliver unprecedented value to our customers. Controlling the entire technology stack in-house enables us to roll out rapid, vehicle-wide OTA software updates that continuously improve and transform the customer ownership experience. This structural advantage is demonstrated by our latest major software deployment, the introduction of Rivian Assistant. Built directly into our vehicle hardware, this next-generation, AI-powered voice assistant transcends basic phone-mirroring systems. Powered by our proprietary, multi-modal AI foundation and an in-house agentic framework, Rivian Assistant possesses deep, context-aware intelligence. It gives drivers voice-activated control over the vehicle’s hardware and features—from toggling drive modes and adjusting ride height to smart navigation, voice-powered messaging, and sophisticated third-party integrations like Google Calendar. Rolling out to all R2 vehicles later this year, and already available in all R1 vehicles, this launch underscores how our pioneering AI-defined vehicles are expected to grow more capable over time, paving the way for high-margin software revenue while providing our customers technology at the cutting edge of automotive innovation.

All rights reserved. 16 LOAN SIZE Up to $4.5B and 80% LTV Includes $0.5B of capitalized Interest during construction, first draw expected by early 2027 STRUCTURE Pro Rata Base and contingent equity will be pre-funded into reserve accounts before first advance INTEREST RATE U.S. Treasury-Equivalent Rate United States Treasury-equivalent yield curve with a 0% credit spread, set at each advance LOAN TERM Up to 15 Years Up to 15 years from the start of amortization in March 2031 FINANCIAL COVENANTS $2B Minimum Liquidity Sponsor covenants include max 55% debt/ tangible assets, min 1.25x current ratio, and $2.0B min consolidated liquidity STRATEGIC CAPITAL ROADMAP We partnered with the DOE for an up to $4.5B loan to build out our Georgia facility, providing low cost financing to scale our U.S. manufacturing and customer base. This funding enables Rivian to establish a stronger leadership position in U.S. technology and job growth. The pro rata draws from the loan and contributed Rivian equity structure require full equity contributions and contingencies to be pre-funded in reserves before the first advance. This derisks construction and facility ramp-up by ensuring capital is fully secured, while accelerating the strategic need for capital to fund these reserves. In early July, Rivian issued 86.25M shares at an offering price of $15.50 per share for net proceeds of approximately $1.3B. These proceeds are expected to be used for general corporate purposes including the funding of certain equity contributions and reserves associated with the DOE loan. 1 Details and defined terms, including financial covenants, are contained in the Amended and Restated Loan Arrangement and Reimbursement and Sponsor Support Agreement 2 Includes the borrowers and guarantors under Rivian’s existing ABL (asset-based lending) credit facility and excludes Rivian and Volkswagen Group Technologies, LLC
