During the second quarter of 2025, we made significant progress across our strategic priorities. We continue to focus on advancing our technologies and vehicle platforms to create technology enabled, compelling products that improve over time. We made progress on our R2 platform and are currently producing design validation vehicles primarily using production tooled parts. We believe R2 will embody the performance, capability, utility, and experience of the Rivian brand, but at a significantly lower price point than R1. We have substantially completed the facilities expansion in Normal, Illinois and have begun installing manufacturing equipment which is designed to manufacture up to 155,000 R2 vehicles annually. Technology is at the core of our vehicles and how we operate. We continue to integrate AI tools to enhance manufacturing, customer interactions, and internal operations, reinforcing the benefits of our vertical integration and direct to customer approach. A large part of our AI development is The Rivian Autonomy Platform. This year, we delivered meaningful updates including an updated autonomy view and enhanced highway assist, as well as a next generation onboard perception model that is more robust in difficult conditions and more responsive to behavior from nearby vehicles. Our in-house vehicle software and electrical hardware design coupled with our high quality perception stack enables the crucial data flywheel for training the Rivian Large Driving Model, a large scale foundation model for driving. Our customer fleet also has the onboard intelligence to identify scenes of interest, catalog them, and prioritize their uploads which is critical to improving the performance of our model. Our early fusion approach, where raw data from sensors is fused into a single representation, operates in an additive way where every sensor increases the fidelity of the output.

In addition to our autonomy system, we continue to make progress on other aspects of software.

Our recently launched customer OTA software updates included an enhanced suspension system

for a smoother low-speed ride and a reimagined in-vehicle energy experience with faster charging times and intelligent charging visuals. In addition, we recently partnered with Google Maps for an integrated and industry-leading navigation experience tailored for Rivian.

The recent launch of our R1 Quad-Motor variant highlights how our technology development has helped advance our flagship product. Within the Quad vehicle we launched a user configurable dynamics mode RAD Tuner. RAD Tuner allows customers to fine-tune vehicle dynamics behavior including torque balance, roll stiffness, ride height, and more. The new Quad-Motor is engineered

for extremes and delivers exceptional performance for any adventure. We believe this variant elevates the R1 platform to a whole new level.

In addition to our technology, we further expanded our footprint. In July, in partnership with the

State of Georgia, we announced our East Coast headquarters in Atlanta which we expect to open later this year. The headquarters will be a focal point for our global growth strategy and a key investment

in a top state for electric mobility. This site will complement our upcoming Georgia manufacturing facility in Stanton Springs North, just outside of Atlanta.

The global economic landscape and the US regulatory environment presents significant uncertainty, particularly regarding evolving trade regulation, policies around regulatory credits and EVs, tariffs, and the overall impact these items may have on our results, consumer sentiment and demand.

These factors have impacted and are expected to continue to impact our global supply chain,

material costs and access, profitability, and capital expenditures. We are actively monitoring

these developments and working to mitigate potential risks through a variety of initiatives including strategic sourcing, operational and cost efficiencies, and proactive engagement with policymakers. While uncertainties persist, we believe we are taking the appropriate steps for our long-term growth, profitability and technology leadership.

During the second quarter, we demonstrated significant progress against our key value drivers:

Technology leadership

•Delivered OTAs providing customers with improved autonomy features, energy experience,

and suspension

•Partnered with Google to provide customers with a superior mapping experience through seamless integration of industry leading maps which include navigation, trip planning, and charging experiences

Demand generation and enhancing customer experience

•Expanded our charging network to have over 780 chargers across 123 sites while maintaining high reliability of 98% uptime in Q2’25

•We currently have 112 locations across service and retail and expect to have over 135 by

the end of 2025

Drive towards profitability

•R2 estimated to be less than half the cost of revenues per unit as compared to R1

•34% gross margin from software and services

Optimize operational efficiency

•Completed phase one of the paint shop upgrade ahead of our R2 launch, expected

to reduce the required downtime starting in September by approximately one week

•Increased the rate of the R1 general assembly line by 36% to more efficiently produce

R1 vehicles

R2 Our excitement for R2 continues to grow as we approach the start of deliveries expected in the first half of 2026. We are currently in the midst of our R2 design validation builds, where we are building R2 vehicles on our pilot line. These builds enable us to validate the performance and capabilities of the full vehicle along with working with our suppliers on their ramp. Importantly, the quality of build, and associated software stability in these early validation vehicles is incredibly high. We strategically invested in development assets and mule vehicles which allowed us to advance development and supplier validation much earlier in the timeline as compared to R1. Many of the leaders helping assemble the vehicles in our pilot production line in California are the same leaders who will manage the production process in Normal, Illinois once we start saleable production expected in the first half of 2026. In preparation for our manufacturing validation builds later this year, we have substantially completed the construction of our new 1.1 million square foot building in Normal, Illinois which will house R2’s general assembly and body shop. Installation of production tooling equipment for component manufacturing is underway and we expect to commission the new R2 line in the third quarter of this year to start validating the equipment and production processes.

Autonomy We have control over the software and hardware on our vehicles, and importantly have the ability to collect the exponentially growing amount of data from our best-in-class on board sensor set. This data collection and processing is ultimately what informs the training process of our core AI models. The Rivian Autonomy Platform is one of our most critical technology focus areas. This platform is designed around a data flywheel for training our Rivian Large Driving Model with an end-to-end approach. Our second generation R1 vehicles include an improved sensor set which offers high quality data from cameras and radars on the vehicles. Our autonomy features continue to improve. Most recently we upgraded our onboard machine learning model, which enables the 360º view to intelligently detect and render vehicles in complex scenarios like crossing traffic and parking lots. This advanced autonomy platform will also be available on R2. We believe high levels of autonomy that can truly offer customers enhanced safety and time back will drive purchase decisions at scale as it transforms the utility of their cars. To further our AI and autonomous driving ambitions, we are opening an office in London. Since the UK is rapidly becoming a leader in AI, establishing a presence there will allow us to tap into this valuable talent pool and complement the world class team we have built at Rivian.

	Software New features deployed via over the air updates continued to make dramatic improvements to our vehicles and customers' experience. Rivian and Google Maps have partnered to build a navigation experience that specifically supports Rivian’s vehicles. This partnership enhances the Rivian user experience through seamless integration offering our customers the best of both worlds. With over 100 million updates a day, Google Maps will provide industry-leading routing, estimated time of arrivals, real-time traffic updates about road disruptions, tappable points of interest, place information, and satellite imagery. In combination with our enhanced in-vehicle charging route planner, these updates improve navigation, trip planning, and charging experiences, empowering customers to confidently embark on their next adventure. In a recent OTA update, the suspension system was enhanced for a more comfortable low speed ride over rough terrain in certain drive modes. Our engineers have developed a smarter way to detect low speed bumps and jolts, using intelligent algorithms that can better analyze the data from sensors around the vehicle. This keeps the comfort valves open for a much wider range of low-speed situations, giving a significantly smoother ride. The in-vehicle energy experience has been completely reimagined. In addition to a brand new user interface, customers will better understand range, know when, how, and where to charge, and how to make the most of the vehicle's capabilities. Improvements to our charging and battery management software systems have enabled up to a 15% improvement in charging efficiency.3

Go-to-Market In the second quarter of 2025, our commercial strategy remained focused on strengthening demand through building brand awareness, deepening our customer engagement, and scaling our commercial infrastructure across the business in preparation for the planned launch of R2 in the first half of 2026. We have 31 spaces including 7 new spaces that opened since the start of the second quarter of 2025, complemented by 81 service locations with the majority providing both sales activities and demo drives. In the second quarter of 2025, we conducted over 26,000 demo drives. We plan to continue expanding our commercial footprint and expect to have over 35 spaces, and over 100 service locations by the end of 2025. The Rivian Adventure Network continues to scale, launching 10 additional sites in the second quarter, now with over 780 chargers across 123 sites in 37 states. Additionally, we upfit more than 40 sites to our latest generation chargers enabling over 65% of the network to be accessible to all electric vehicles. This widens our ability to provide reliable, quality charging to all, and to introduce more EV drivers to the Rivian brand. The Rivian Adventure Network also introduced off-peak pricing at many sites, offering drivers the flexibility to save at charging throughout the day.

R1 Quad Launch In July, we launched and started deliveries of our second-generation Quad-Motor R1. Our new Quad-Motor system was designed to be the pinnacle variant of our R1 lineup with more power and capability, and more fun to drive than any of our previous R1 models. The Quad-Motor comes with a range of new software features including launch mode with launch cam, RAD Tuner, and a kick turn feature making it easier to steer in off-road conditions by controlling the power and tire grip, letting the vehicle spin about its center, even when it's moving. RAD Tuner allows customers to use intuitive sliders to adjust handling and performance settings with the ability to save drive modes for later. The feature allows the boundaries of the vehicle to be pushed through adjusting torque balance, roll stiffness, ride height, and more to transform the character of the vehicle. The Quad-Motor R1 is powered by our newest drive unit, featuring four in-house designed and manufactured motors, powering both the front and rear. The front motors are smaller, optimized for efficiency at cruising speeds. The rear motors are much larger, geared to maximize torque to the tires’ traction limit. Offering an EPA-estimated up to 374 miles of range (and up to 400 miles in Conserve mode), not only is the Quad-Motor R1 more powerful and capable than any of our previous R1 models, but it enables customers to go further on road trips. The vehicles feature a native NACS charge port. This allows customers easier access and even more convenient charging across North America.

Production and Deliveries In the second quarter of 2025, we produced 5,979 and delivered 10,661 vehicles in our manufacturing facility in Normal, Illinois. Production during the second quarter for both our R1 products and commercial vans was limited due to a variety of supply chain related complexities partially driven by shifts in trade policy. In addition to the model year cutover, at the end of the second quarter, we took one week of downtime in the Normal Plant to complete the first phase of the paint shop upgrade in preparation for R2. Starting in September, we expect the production lines to be down for approximately three weeks as we increase the annual production capacity of the Normal Plant to approximately 215,000 units. We anticipate the third quarter to be our highest delivery quarter for the year across both our consumer and commercial vehicles.

Revenues Automotive Total automotive revenues for the second quarter of 2025 were $927 million compared to $1,074 million in the same period in 2024. This decrease was primarily due to higher sales in the prior period associated with sales of first generation R1 vehicles ahead of the second generation introduction as well as commercial vans, partially offset by increased average selling prices. Software and Services Total software and services revenues for the second quarter of 2025 were $376 million compared to $84 million in the same period in 2024, primarily due to vehicle electrical architecture and software development services that were not performed during the prior period, an increase in remarketing sales, and increased vehicle repair and maintenance service. During the second quarter of 2025, we recognized revenue of approximately $182 million for the combined performance obligation of the joint venture. This revenue was recognized both from the ongoing payments to fund the joint venture's development services as well as from the $1,960 million of consideration that was received in conjunction with the closing of the joint venture. We expect the remainder of the consideration received at closing will be fully recognized as revenue over approximately the next three years. We expect the amount of revenue recognized each period will gradually increase over time as the joint venture ramps its operations and progresses toward completing its performance obligation. Consolidated Total consolidated revenues were $1,303 million for the second quarter of 2025, compared to $1,158 million in the same quarter in 2024.

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 and cash 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.
	Our non-GAAP financial measures include adjusted research and development expenses, adjusted selling, general, and administrative expenses, total adjusted operating expenses, adjusted EBITDA, adjusted net loss, adjusted net loss per share, and free cash flow. Adjusted research and development expenses is defined as total research and development expenses, less R&D depreciation and amortization expenses and R&D stock-based compensation expenses. Adjusted selling, general, and administrative expenses is defined as total selling, general, and administrative expenses, less SG&A depreciation and amortization expenses and SG&A stock-based compensation expenses. Adjusted operating expenses is defined as total operating expenses, less R&D depreciation and amortization expenses, R&D stock-based compensation expenses, SG&A depreciation and amortization expenses, and SG&A stock-based compensation expenses.
	Adjusted EBITDA is defined as net loss before interest expense (income), net, provision for income taxes, depreciation and amortization, stock-based compensation, other expense (income), net, and special items. Our management team ordinarily excludes special items from its review of the results of the ongoing operations. Special items is comprised of (i) cost of revenue efficiency initiatives which include costs incurred as we transition between major vehicle programs, cost incurred for negotiations with major suppliers regarding changing demand forecasts or design modifications, and other costs for enhancing capital and cost optimization of the Company (ii) restructuring expenses for significant actions taken by the Company, (iii) significant asset impairments and write-offs, and (iv) other items that we do not necessarily consider to be indicative of earnings from ongoing operating activities, including loss (gain) on convertible note, net, and joint venture formation expenses. Adjusted net loss is defined as net loss before stock-based compensation expense, other (expense) income, and special items. Our management team ordinarily excludes special items from its review of the results of the ongoing operations. Special items is comprised of (i) cost of revenue efficiency initiatives which include costs incurred as we transition between major vehicle programs, cost incurred for negotiations with major suppliers regarding changing demand forecasts or design modifications, and other costs for enhancing capital and cost optimization of the Company (ii) restructuring expenses for significant actions taken by the Company, (iii) significant asset impairments and write-offs, and (iv) other items that we do not necessarily consider to be indicative of earnings from ongoing operating activities, including loss (gain) on convertible note, net, and joint venture formation expenses. Adjusted net loss per share is defined as adjusted net loss divided by the weighted-average common shares outstanding. Free cash flow is defined as net cash used in operating activities less capital expenditures.
