Rivian Releases First Quarter 2026 Financial Results

•Started production of saleable R2 vehicles and made first deliveries to employees with external customer deliveries expected in the coming weeks

•Consolidated revenue growth of 11 percent year-over-year and generated $119 million of consolidated gross profit for the quarter

•Increased Georgia plant initial production capacity to 300,000 vehicles annually; expects first advance on $4.5 billion DOE loan in early 2027

•Robotaxi partnership with Uber to deploy up to 50,000 fully autonomous robotaxis

•$1 billion of funding from Volkswagen Group through successful completion of winter testing

Irvine, California, April 30, 2026: Rivian Automotive, Inc. (NASDAQ: RIVN), an American automotive technology company that develops and manufactures category-defining electric vehicles as well as vertically integrated software and services for the entire lifecycle of the vehicle, today announced its first quarter 2026 financial results.

RJ Scaringe, Rivian Founder and CEO, said:

“With the launch of R2, we are excited to dramatically expand our market opportunity and have more people driving Rivians. The support of the Department of Energy for the $4.5 billion loan to build our Georgia facility enables Rivian to grow American jobs and establish stronger U.S. technology and manufacturing leadership while further scaling our customer base.”

Business Highlights

Last week Rivian announced the start of production of saleable R2 vehicles in Normal, Illinois. This key step is an exciting milestone in Rivian’s history and is the culmination of the hard work from many teams across the company. With R2, Rivian has taken its design, performance and technology and brought it to a significantly broader audience without losing what makes a Rivian unmistakably Rivian.

The company made the strategic decision to increase the initial production capacity of its Georgia plant by 50 percent, bringing the first phase to 300,000 units of annual production capacity for the company’s mid-sized vehicle platform. This change is expected to boost cost efficiency while still providing significant room for future expansion in later phases. The company remains on track for vehicle production in Georgia to begin in late 2028.

As part of this new vision for the Georgia facility, Rivian worked with the Department of Energy to make strategic changes to the company’s DOE loan. The up to $4.5 billion loan ($4,006 million principal and $494 million capitalized interest) is aligned with the updated facility design. Rivian now expects to draw on the loan by early 2027, subject to meeting certain conditions.

In March, Rivian announced a partnership with Uber to help accelerate both companies’ autonomous vehicle plans. The deal is expected to enable Uber, or its fleet partners, to purchase 10,000 fully autonomous R2 robotaxis with the option to purchase up to 40,000 more in 2030. Uber will invest up to $1.25 billion in Rivian through 2031, subject to the achievement of certain milestones and conditions, building towards a scaled, fully-autonomous fleet of Rivian R2 robotaxis, which will be available through the Uber platform. An initial $300 million equity investment is expected to close in the second quarter of 2026, subject to certain conditions, and an additional $250 million equity investment is expected later this year, subject to certain conditions.

Last month, Rivian’s joint venture with Volkswagen Group, Rivian and Volkswagen Group Technologies (RV Tech), successfully completed winter weather testing of its production-intent zonal architecture for first generation software-defined vehicles. Achieving this milestone unlocked a $1 billion equity investment in Rivian by Volkswagen Group, which we received today.

First Quarter 2026 Results Summary

Production and Deliveries

•10,236 vehicles produced at Rivian’s manufacturing facility in Normal, Illinois.

•10,365 vehicles delivered to customers.

Revenues

•Consolidated revenue was $1,381 million, an 11 percent increase over the same quarter of the previous year.

◦Automotive segment revenue was $908 million, a 2 percent decrease over the same quarter of the previous year, primarily due to a $100 million decrease in sales of automotive regulatory credits and a decline in automotive revenue per unit delivered due to a higher mix of commercial vans, which were partially offset by a 20 percent increase in vehicle deliveries.

◦Software and services segment revenue was $473 million, a 49 percent increase over the same quarter of the previous year, due to an increase in vehicle electrical architecture and software development services, as well as vehicle repair and maintenance service and remarketing.

Gross Profit

•Consolidated gross profit was $119 million, an $87 million decrease over the same quarter in the previous year.

◦Automotive segment gross profit loss was $(62) million compared to $92 million in gross profit for the same quarter in 2025, due primarily to the $100 million decrease in sales of automotive regulatory credits and lower production volumes, resulting in a $42 million and $3 million increase in depreciation and stock based compensation respectively.

◦Software and services segment gross profit was $181 million, a $67 million increase over the same quarter of the previous year, primarily due to higher vehicle electrical architecture and software development services and vehicle repair and maintenance services.

Operating Expenses and Operating Loss

•Total operating expenses in the first quarter increased to $1,000 million, compared to $861 million in the same quarter of the previous year. Within operating expenses, we recognized non-cash, stock-based compensation expenses of $180 million compared to $159 million in the same quarter of the previous year and depreciation and amortization expense of $80 million as compared to $72 million in the same quarter of the previous year.

◦Research and development (R&D) expense was $458 million compared to $381 million in the same quarter of the previous year. The increase was primarily related to increased software and cloud spend on autonomy and R2 pre-production costs, including payroll and related expenses.

◦Selling, general and administrative (SG&A) expense was $542 million compared to $480 million in the same quarter the previous year. The increase was primarily related to

expanding our go-to-market operations and footprint, including higher payroll and stock-based compensation expenses and facilities, software, and other operating expenses.

•For the first quarter of 2026, we experienced a loss from operations of $881 million compared to $655 million in the same quarter of the previous year due to lower gross profit and higher operating expenses.

Adjusted Operating Expenses

•Total adjusted operating expenses for the first quarter of 2026 were $740 million compared to $630 million for the same quarter of the previous year.

◦Adjusted R&D expenses for the first quarter of 2026 were $348 million compared to $285 million for the same quarter the previous year.

◦Adjusted SG&A expenses for the first quarter of 2026 were $392 million compared to $345 million for the same quarter the previous year.

Net Loss

•Net loss for the first quarter of 2026 was $(416) million compared to $(541) million for the same quarter the previous year. Net loss for the quarter benefited from a $506 million gain in other income related to the Series A capital raise and related deconsolidation of Mind Robotics.

Adjusted EBITDA

•Adjusted EBITDA for the first quarter of 2026 was $(472) million compared to $(329) million for the same quarter the previous year.

Net Cash Used in Operating Activities

•Net cash used in operating activities for the first quarter of 2026 was $(703) million compared to $(188) million for the same quarter the previous year. The increase in net cash used in operations was primarily driven by cash consumed by working capital, increased operating expenses, and a reduction in regulatory credit sales.

Capital Expenditures

•Capital expenditures for the first quarter of 2026 were $372 million compared to $338 million for the same quarter the previous year.

Liquidity and Free Cash Flow

•Rivian ended the first quarter of 2026 with $4,830 million in cash, cash equivalents, and short-term investments.

◦Including the capacity under our asset-based revolving-credit facility, we ended the first quarter of 2026 with $5,394 million of total liquidity.

•We define free cash flow as net cash used or provided by operating activities less capital expenditures. The increase in net cash used in operating activities coupled with the increase in capital expenditures discussed above resulted in negative free cash flow¹ of $(1,075) million for the first quarter of 2026 compared to negative free cash flow of $(526) million for the same quarter the previous year.

Current Outlook

Vehicles Delivered 62,000 - 67,000

*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.

Our non-GAAP financial measures include adjusted research and development expenses, adjusted selling, general, and administrative expenses, adjusted EBITDA, 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 EBITDA 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.

Free cash flow is defined as net cash used in operating activities less capital expenditures.

This quarter the Rivian team executed across many fronts, laying a strong foundation for the years ahead. As an American automotive technology company, we are building for a future that we believe will be fully electric, autonomous and AI-defined. With our category-defining brand, the start of production and deliveries of R2, our technology roadmap and a direct-to-customer ownership experience, we are excited about the opportunity ahead for our customers and our business. R2 Start of Saleable Production Last week in Normal, Illinois, our team celebrated the start of saleable R2 production. It is an exciting milestone in Rivian’s history and is the culmination of all the hard work and energy from so many people across the company. In an American automotive marketplace starved for high-quality EV choice, we believe R2 is an attractively priced option that is sized for everyday adventures. We could not be more excited to start getting this incredible vehicle in the hands of our customers this spring. Optimized Capacity for Georgia and Department of Energy Loan We are pleased to partner with the U.S. Department of Energy ("DOE") to grow our manufacturing footprint in Georgia. We made the strategic decision to increase the initial phase of production capacity by 50%, bringing it to 300,000 units for our mid-sized vehicle platform. This change is expected to boost cost efficiency, while still providing significant room for future expansion in later phases.The up to $4.5 billion DOE loan ($4,006 million principal and $494 million capitalized interest) to build our Georgia facility provides low cost financing that will enable Rivian to grow American jobs and establish stronger U.S. technology and manufacturing leadership while further scaling our customer base. Strategic Partnership Updates In March, we were excited to announce a new partnership with Uber to accelerate our shared autonomous vehicle goals, including plans for future R2 robotaxis. This partnership includes an investment of up to $1.25 billion from Uber subject to technical milestones and conditions. Additionally, the Rivian and Volkswagen Group Technologies joint venture ("RV Tech") successfully completed winter weather testing of its production-intent zonal architecture for first generation Volkswagen Group software-defined vehicles. Achieving this milestone unlocked a $1 billion investment in Rivian by Volkswagen Group which we received today. Quarterly Financial Highlights In the first quarter, Rivian generated approximately $1.4 billion of revenue, an 11% increase over the same quarter last year driven by a 20% year-over-year increase in delivery volumes and a strong performance from our software and services segment. Gross profit was $119 million. 4Q1 2026 Earnings Presentation © 2026 Rivian. All rights reserved.

All rights reserved. Progress on Rivian's Strategic Priorities Scaling R2 production and deliveries enables path to profitability

Production of saleable R2 commenced with external customer deliveries expected in the coming weeks Trims, Pricing and First Deliveries from Normal In an American automotive marketplace starved for high-quality EV choice, we believe R 2 is an attractively priced option sized for everyday adventures — from school pickups to weekend excursions. R 2 brings Rivian’s design, performance and technology to a significantly broader audience with an array of trims to accommodate our customers' varying needs and driving styles: • R 2 Performance debuts in the spring and is the most capable R 2 on- and -off road; it is a dual-motor AWD variant with a staggering 656 horsepower and an EPA-estimated range of up to 330 miles • R 2 Premium is expected to be available late this year and is elevated inside and out; it features a dual-motor AWD setup that produces 450 horsepower and an EPA-estimated range of up to 330 miles • R 2 Standard is expected to be available in the first half of 2027 and redefines expectations for the mid-size SUV segment; the RWD long-range configuration of R2 Standard delivers 350 horsepower and a Rivian-estimated range of up to 345 miles • An additional R 2 Standard variant starting at around $45,000 is expected to start deliveries in late 2027 We were excited to celebrate another key milestone with the start of saleable R 2 series production last week. This key step is the culmination of hard work from so many team members as we gear up for expected customer deliveries to the public in the coming weeks. We’ve already begun delivering R 2 vehicles to our employees. We could not be more excited to get this incredible vehicle in the hands of our customers this spring. Q1 2026 Earnings Presentation © 2026 Rivian. All rights reserved. 6 R2 is Designed for Big Adventures and Everyday Use

Profitably Delivering R2 at an Accessible Price 7 R2 bill of materials expected to be approximately 50% of R1 and non-BOM costs expected to decline greater than 50% due to focus on design for manufacturing and fixed cost efficiencies1 Key Design Changes & Sourcing Leverage Structural cost reductions from design changes, sourcing leverage and manufacturing simplicity2 Fixed Costs Depreciation and conversion costs absorbed over more units increasing profitability Front Suspension Strut architecture delivering over 70% savings vs. R1 double-wishbone Maximus Drive Unit ~30% piece cost savings; integrated side-mounted inverter Power Conversion 5-to-1 module consolidation with integrated electronics; ~70% reduction in high-voltage cabling Battery Pack Floor to pack design; 4695 Structural Pack Underbody Structure Utilizing large high pressure die casting resulting in over 90% fewer parts and ~30% piece cost reduction Corner Radar and Ultrasonic Sensors Over 50% savings from removing the ultrasonic sensors and sourcing leverage on corner radars Q1 2026 Earnings Presentation © 2026 Rivian. All rights reserved. 1 Based on average vehicle cost as of the end of 2027 2 Percentage savings represent the expected decrease in cost of components for R2 vs. R1 production Rear Doors ~65% part count reduction and ~55% savings from design optimization Low Voltage Harnesses 2.3 mile reduction in harness length and over 60% reduction in the number of in-line connectors Front Windshield ~50% savings predominantly from sourcing leverage

Site capacity does not equal current production rates. There may be limitations discovered as production rates approach capacity. Production rates depend on a variety of factors, including equipment uptime, component supply, downtime related to factory upgrades, regulatory considerations and other factors. Optimized Capacity for Georgia Plant 50% increase in phase one expected to boost cost efficiency and support thousands of U.S. manufacturing jobs We updated capacity for our Georgia plant allowing for a 50% increase in initial production capacity to 300,000 units annually for our mid-sized platform. This change is expected to boost cost efficiency, while still providing significant room for future expansion in later phases. The company remains on track for vehicle production in Georgia to begin in late 2028. As part of this new vision for our Georgia facility, Rivian worked with the Department of Energy to make strategic changes to the company’s DOE loan. The up to $4.5 billion loan ($4,006 million principal and $494 million capitalized interest) provides low-cost financing for our Georgia plant. Rivian expects to draw on the loan by early 2027, subject to meeting certain conditions. Q1 2026 Earnings Presentation © 2026 Rivian.

Strategic Partnerships Update Highlights extensibility of our technology and vehicle programs to drive value Robotaxi Partnership with Uber In March, we announced a new partnership with Uber to accelerate our shared autonomous vehicle goals, including plans for future R 2 robotaxis. We believe this partnership is an important validation of our technology roadmap and vertically integrated approach. At the core of our platform is the Rivian Autonomy Processor (RAP1), our multi-modal perception platform (cameras, radar and LiDAR) and our AI-based approach to building our Large Driving Model with the data flywheel from our growing car parc. Key elements of the partnership included an expected investment of up to $1.25 billion in Rivian through 2031 based on the achievement of autonomous performance milestones, a vehicle purchase commitment by Uber, or its fleet partners, for up to 50,000 fully autonomous R 2 robotaxis and certain software licensing fees in connection with its use of Rivian’s Level 4 autonomous driving software system, subject to meeting certain conditions. Q1 2026 Earnings Presentation © 2026 Rivian. All rights reserved. 9 Completion of Key Winter Testing Milestones by RV Tech In March, RV Tech successfully completed winter testing of production-intent zonal architecture developed for the first generation of Volkswagen Group software-defined vehicles. Testing took place over several months in Phoenix (USA) and Arjeplog (Sweden) by a joint team from Volkswagen, Audi, and Scout brands and RV Tech. Tests included validating functionality and performance of the electronics and software, including OTA functionality — an important milestone for the joint venture’s ongoing development work. This milestone unlocked the next phase of equity investment from Volkswagen Group to Rivian of $1 billion which we received today.

Strategic Investments Update Funding momentum for Rivian spin out companies Mind Robotics Series A Funding Late last year, the company established Mind Robotics to address a structural gap with current industrial automation solutions. Existing industrial robotics can perform repeatable dimensionally stable tasks, but a large share of factory value-add work requires human-like dexterity, adaptation and physical reasoning that current robotics cannot address. Mind Robotics is building the AI foundation — models, hardware, and deployment infrastructure — to close that gap. In March, Mind Robotics announced it raised $500 million in a Series A funding co-led by venture capital firms Accel and Andreessen Horowitz. As of March 31, 2026, Rivian’s ownership interest was approximately 38% on a shares outstanding basis. Q1 2026 Earnings Presentation © 2026 Rivian. All rights reserved. 10 ALSO. Series C Funding and DoorDash Partnership Bike lanes, shoulders and curbsides are the areas that make up the hardest part of the last-mile delivery puzzle. They are also where traditional vehicles struggle most and where smaller, more adaptable EVs like those being designed by ALSO have the greatest opportunity to perform. In March ALSO, Rivian’s micro mobility spin-off, announced a strategic investment and multi-year commercial collaboration with DoorDash to develop and deploy small, purpose-built EVs designed to optimize how goods move in dynamic, population-dense environments. This collaboration comes alongside ALSO’s $200 million Series C financing round led by Greenoaks, with participation from Prysm Capital and strategic investment from DoorDash. In addition, Amazon has partnered with ALSO to purchase thousands of pedal-assist electric cargo quads, known as the TM-Q. As of March 31, 2026, Rivian’s ownership interest was approximately 35% on a shares outstanding basis.
