Q3 2024 Shareholder Letter © 2024 Rivian. All rights reserved. 2

During the third quarter of 2024, we made progress advancing R2 development, driving greater efficiency in operating expenses, launching new R1 variants, investing in our go-to-market infrastructure, and introducing new services to further improve the customer experience. We continue to see cost progress from our second generation R1 vehicles which we expect to be represented in the fourth quarter when we anticipate achieving modest positive gross profit. Rivian produced 13,157 vehicles and delivered 10,018 vehicles during the third quarter of 2024. As previously disclosed, Rivian is experiencing a production disruption due to a shortage of a shared component within our Enduro motor system on the R1 and RCV platforms. Our team has a strong sense of urgency in finding a solution as we work in close partnership with the supplier to ramp additional capacity to accommodate planned production. Over the long-term we believe Rivian’s value will be determined by the scale it can reach with its midsize platform including the R2, R3, and R3X, as well as our ability to continue to reduce costs and develop differentiated technologies. Our midsize platform is expected to address global market segments and is designed to build upon our industry-leading technology platform as well as our focus on reducing manufacturing complexity and cost efficiency. Our team is laser-focused on executing the development plan for R2. The recent transition to our second generation R1 vehicles has implemented multiple new technologies which will serve as the foundation for our midsize platform such as our zonal network architecture and Rivian Autonomous Platform, positioning R2 for a simplified launch. We believe the formation of the expected joint venture with Volkswagen Group will be a landmark development for the industry. The joint venture will benefit from Rivian's differentiated and well-proven zonal network architecture and full-stack software technologies as well as enhanced software and electrical architecture innovation. The upcoming partnership with Volkswagen Group validates Rivian’s technology leadership and creates new growth opportunities for Rivian to be a technology partner to other manufacturers. The joint venture is expected to provide a meaningful financial opportunity for Rivian with a total deal size of approximately $5 billion, in addition to the annual operating expense savings Rivian expects to realize. The planned investments by Volkswagen Group in addition to our current cash, cash equivalents, and short-term investments are expected to provide the capital to fund Rivian’s operations through the ramp of R2 in Normal, as well as the midsize platform in Georgia – enabling a path to positive free cash flow and meaningful scale.

	We believe the introduction of our second generation R1, along with the formation of the joint venture, will enhance execution against our core value drivers: Focus on demand generation and enhancing the customer experience: Demand for R1 vehicles was negatively impacted in the third quarter of 2024 by the production disruption and a challenging consumer backdrop. We remain focused on maximizing the levers within our control and strategically investing in our go-to-market strategy. We continue to make progress expanding our commercial footprint and enabling the opportunity for more potential customers to experience Rivian vehicles. In the third quarter of 2024, we increased our total demo drives by approximately 20% as compared to the second quarter of 2024. Optimize operational efficiency: We continue to focus on maximizing spend efficiency across all aspects of the organization. As compared to the second quarter of 2024, third quarter of 2024 GAAP operating expenses were down $147 million, marking our lowest quarter in the last three years. Excluding stock-based compensation and depreciation and amortization, our adjusted operating expenses1 for the quarter were down $77 million as compared to the prior quarter. Technology leadership: We believe technology is a competitive differentiator for Rivian. Our midsize platform is designed to build upon our industry-leading technology platform. We expect the midsize platform to benefit from the key vertically integrated technologies developed for R1 including our in-house software stack, propulsion technology, network architecture, and vehicle electronics. Drive towards profitability: We are seeing meaningful progress on our second generation R1 material costs due to the new technologies incorporated into the vehicle and manufacturing process. The introduction of the second generation R1 platform combined with commercial cost improvements and commodity tail winds are expected to enable a 20% material cost reduction when comparing an R1 Dual-Motor with Large Pack produced in the first quarter of 2024 versus the same vehicle produced in fourth quarter of 2024. In the third quarter of 2024, we have already seen reductions in our material cost in line with our target. In addition, we have made meaningful progress in sourcing components for R2. We are approximately 85% through the sourcing of R2 bill of materials and are currently in line with our cost targets. We anticipate the material cost of an R2 AWD Large vehicle to be 45% lower than a second generation R1 Dual Large vehicle. We want to thank our employees, customers, suppliers, partners, communities, and shareholders for their continued support of our vision.

R2 Progress We believe R2 will be a fundamental driver of Rivian’s growth and profit potential. It allows Rivian to address global market segments and is designed to build upon our industry-leading technology platform. R2 will benefit from vertically integrated technologies developed for R1 including our in-house software stack, propulsion technology, network architecture, and vehicle electronics. R2 development has focused on reducing the number of parts, joints, and fasteners in a focused effort to drive manufacturing simplicity. This includes a structural battery pack that serves as the floor of the vehicle, large structural die castings, further electronics consolidation enabling harness simplification, and a wide range of design decisions to enable low cost execution. We have made meaningful progress in sourcing components for R2. We are approximately 85% through the sourcing of R2 bill of materials and are currently in line with our cost targets.

Q3 2024 Shareholder Letter © 2024 Rivian. All rights reserved. 7

	In addition, we continue to make rapid progress in Normal constructing our facility expansion which will house the general assembly, body shop, and end of line for R2 production. This is a critical step to achieve our target of launching R2 in the first half of 2026.

Update on R2 Propulsion Today we announced an important strategic partnership with LG Energy Solution (LGES) to supply US manufactured cells for our upcoming R2 vehicle. LGES will provide 4695 cylindrical batteries enabling high-quality, advanced battery technology to our vehicles, ensuring long range and segment-leading performance. The agreement also pioneers a plethora of supply chain innovations and strengthens domestic sourcing for battery materials. Within the first year of production, the batteries are expected to be manufactured at LGES' Queen Creek, Arizona plant, aligning with Rivian's focus on U.S. domestic manufacturing and IRA compliance. Our battery pack architecture is expected to continue to evolve and improve with R2 and R3. It will be based upon a simplified pack structure which reduces weight, complexity, and cost while also having greater energy density. We expect a meaningful reduction in dollar per kilowatt hour (kWh) at the pack level when compared to the R1 platform. In addition, the 4695 is a larger cell form factor than R1 which allows for reduced cell count for improved manufacturability. We expect battery pack assembly processing to improve by approximately 45%.

Software Our intentional decision to own the software and technology hardware stack in the vehicle has been focused on an improved experience for our customers. Rivian customers enjoy continuous enhancement to their vehicles via frequent over the air updates, with over 35 updates made to the vehicles since launching. Rivian’s software platform allows seamless integration of the services for simple, convenient, and immersive infotainment experience. Available applications now include Apple Music and Audible with Google Cast and YouTube coming later this year. This quarter we introduced Connect+, a streaming and connectivity service providing customers music, audio, in-vehicle hotspot, and video streaming connectivity with an easy monthly or annual subscription. Included within Connect+ subscription, customers can now access the Gear Guard Live Cam feature offering peace of mind from in or away from the vehicle. The system includes high-resolution cameras embedded around the vehicle, physical cables that secure your gear, and an attentive animation on the center display. With this update, customers can see what is happening in and around their vehicle from almost anywhere via the Rivian mobile app. Following the launch of Connect+, we provided customers a 60 day free trial period; we have seen the majority of R1 customers have subscribed to Connect+ following the free trial period.

R1 Update The second generation of R1 vehicles have hundreds of design, engineering, and performance upgrades to provide a superior customer experience and a meaningful improvement to the cost structure of the vehicle. As a result of these changes, the material cost of the R1 vehicle is now meaningfully lower when comparing a vehicle produced in the first quarter of 2024 to a vehicle produced in the third quarter of 2024. The introduction of the second generation R1 platform combined with commercial cost improvements and commodity tail winds are expected to enable a 20% material cost reduction when comparing an R1 Dual-Motor with Large Pack produced in the first quarter of 2024 versus the same vehicle produced in the fourth quarter of 2024. We recently launched our Tri-Motor R1 configuration, combining performance levels that surpass our original quad motor offerings. Tri-Motor packs two of our Ascent motors in the rear and one Enduro motor in front for a blend of exceptional power and range. With 850 horsepower and 1,103 Ib-ft of torque, it reaches 0-60 mph in 2.9 seconds and when driving in Conserve mode has 405 miles of range. In addition, we expect to launch the Quad-Motor variant in 2025. The Quad-Motor variant has two smaller motors in the front, optimized for efficiency at cruising speeds and two in the rear delivering 0-60 mph in 2.5 seconds and 1,025 horsepower. Both the Tri-Motor and Quad-Motor are equipped with our new Ascend premium interior offering. In both Tri- and Quad- variants, while operating in Conserve mode, an automatic rear disconnect ensures AWD performance is always available, but intuitively turns off when driving demand doesn't require it, helping you maximize range when you need it, and performance when you want it. All Rivian motors are oil-cooled, significantly improving thermal performance during high-torque, low-speed driving such as rock crawling while also improving range efficiency during low-torque, high-speed cruising.

Go-to-Market We remain focused on our top of funnel demand generation as we expand our presence across the country and get more customers into vehicles for demo drives. We currently have 16 spaces including six new spaces opened since the start of the the third quarter of 2024 in Yosemite, San Diego, Nashville, Boston, Scottsdale, and Chicago and have 62 service locations with the majority staffed for sales and demo drives. In the third quarter of 2024, we conducted over 29,000 demo drives and launched our consumer referral program. While we anticipate a challenging consumer backdrop in the near-term, we continue to see a significant opportunity to increase our brand awareness and have more customers behind the wheel of our award-winning products.

Production and Deliveries In the third quarter of 2024, we produced 13,157 vehicles and delivered 10,018 vehicles. During the third quarter of 2024, we experienced a production disruption due to a shortage of a component within our Enduro motor system. The Enduro motor is our in-house single-motor-per-axle system used in our R1 vehicles as both motors in the Dual-Motor variant, and one of the motors in the Tri-Motor variant, as well as our commercial vans as the single motor. We expect to produce more Tri-Motors and commercial vans as a mitigating factor to the supply constraint, with Amazon increasing its delivery order of vans in the fourth quarter of 2024. Demand for R1 vehicles was negatively impacted in the third quarter of 2024 by the production disruption and challenging consumer backdrop. Due to the sequential production ramp following the plant retooling upgrade, the part shortage limited availability of specific R1 variants for sale.

Path to Profitability Our long-term success and ability to make an impact will ultimately be determined by our ability to operate profitably and generate cash flow. Over the past few years, we have taken significant steps to reduce our capital expenditures and overhead costs. This includes our decision to bring the first line of R2 production to Normal and other organizational changes we have made. In addition, we remain focused on generating positive gross margins through improved unit economics on our vehicle platforms. We expect to generate modest positive gross margin in the fourth quarter of 2024 supported by the following key drivers: •Revenue per unit: We anticipate an increase in revenue per unit delivered mainly driven by the increase in non-vehicle revenues such as the sale of regulatory credits, vehicle service, remarketing, software, and other services. In addition, we anticipate the average selling price per vehicle to increase due to the higher mix of second generation R1 vehicles and more premium variants like the Tri-Motor, partially offset by an increased mix of commercial vans. •Variable costs: As part of the cutover to our second generation R1 vehicles, we are starting to see significantly improved material costs associated with our R1 vehicles. These benefits are due to design changes, supplier negotiations, and lower raw material costs. We also expect the variable cost per unit delivered to benefit from an increase in the mix of commercial van sales. •Fixed and semi-fixed costs: We have made changes to the design of our vehicles and manufacturing process which we expect to significantly reduce our fixed costs per vehicle delivered in the fourth quarter of 2024. We also expect our ending inventory lower of cost or net realizable value (LCNRV) and liabilities for losses on firm purchase commitments balances to continue decreasing.

2024 Outlook During the third quarter of 2024, we took meaningful steps to enhance the profitability of our second generation R1 vehicles. We are reaffirming our production guidance of between 47,000 to 49,000 vehicles. We are reaffirming our delivery outlook of between 50,500 to 52,000 vehicles and $1,200 million in capital expenditures. The lower production outlook for 2024 has a negative impact on our profitability for 2024 due to our limited ability to leverage the fixed costs of our production facility. Because of this, we are revising our annual adjusted EBITDA guidance to between a $(2.825) billion loss to a $(2.875) billion loss.

Revenues

Total revenues for the third quarter of 2024 were $874 million, primarily driven by the delivery of 10,018 vehicles. Total revenues from the sale of regulatory credits were $8 million for the quarter. Compared to the third quarter of 2023, a portion of the decrease was driven by timing of higher EDV deliveries in the third quarter of 2023 following the first quarter of 2023 line shutdown. The remaining portion of the decrease was driven in part from our production disruption causing a limited number of R1 variants being available for sale and a more challenging consumer environment.

Gross Profit

We generated negative gross profit of $(392) million for the third quarter of 2024 as compared to $(477) million for the third quarter of 2023. Gross profit losses decreased year-over-year primarily due to lower delivery volume. Gross profit losses per unit increased primarily due to an increase in cost of revenue efficiency initiatives and smaller reduction in LCNRV of inventory and losses on firm purchase commitments. Cost of revenues for the third quarter of 2024 included $37 million of costs we do not anticipate being part of our long-term cost structure. This was made up of cost of revenue efficiency initiatives primarily related to certain supplier liabilities incurred. The third quarter of 2024 was impacted by a charge for LCNRV write-downs on inventory and losses on firm purchase commitments. Our ending inventory balance includes LCNRV write-downs of $130 million while liabilities for losses on firm purchase commitments were $10 million, for a total of $140 million at the end of the third quarter of 2024 as compared to our ending inventory balance LCNRV write-downs of $292 million and liabilities for losses on firm purchase commitments of $160 million, for a total of $452 million at the end of the third quarter of 2023. The decrease is primarily due to an increase in projected positive-margin variants and a decrease in estimated materials’ costs for the projected negative-margin variants. We expect LCNRV write-downs of inventory and losses on firm purchase commitments to continue to decrease over time as we further reduce the cost to manufacture our products. The key drivers of our path to positive gross profit include increasing our revenues per delivered unit, reducing variable costs, and reducing fixed and semi-fixed costs.

Operating Expenses and Operating Loss	Total operating expenses in the third quarter of 2024 decreased to $777 million, as compared to $963 million in the same period last year. In the third quarter of 2024, we recognized non-cash, stock-based compensation expense within operating expenses of $105 million as compared to $219 million in the third quarter of 2023 and depreciation and amortization expense within operating expenses of $73 million as compared to $80 million in the third quarter of 2023. Research and development (“R&D”) expense in the third quarter of 2024 was $350 million, as compared to $529 million in the same period last year. The decrease was primarily due to a $74 million decrease in stock-based compensation expense primarily related to a reversal in the accrual of a previously recorded stock-based bonus expense and decreased grants, a $57 million decrease in engineering, design, and development costs and other related project costs primarily surrounding the R1 platform design and technology upgrades, and a $30 million decrease in depreciation and amortization. Selling, general, and administrative (“SG&A”) expense in the third quarter of 2024 was $427 million, as compared to $434 million in the same period last year. SG&A expenses remained relatively flat compared to three months ended September 30, 2023, with a $40 million decrease in stock-based compensation expense primarily related to a reversal in the accrual of a previously recorded stock-based bonus expense offset by a $23 million increase in depreciation and amortization and a $17 million increase in sales and marketing expenses to support go-to-market operations. We experienced a loss from operations in the third quarter of 2024 totaling $(1,169) million, as compared to $(1,440) million in the same period last year.
Adjusted Operating Expenses (Non-GAAP)¹	Adjusted R&D¹ for the third quarter of 2024 was $271 million as compared to $346 million for the same period last year.

Liquidity and Free Cash Flow (non-GAAP)¹	We ended the third quarter of 2024 with $6,739 million in cash, cash equivalents, and short-term investments. Including the capacity under our asset-based revolving-credit facility, we ended the third quarter of 2024 with $8,105 million of total liquidity. The third quarter of 2024’s ending cash, cash equivalents, and short-term investments balance of $6,739 million includes $1 billion of an unsecured convertible note issued to Volkswagen International America, Inc. in association with the announcement of our expected joint venture with Volkswagen Group. The convertible note will automatically convert into shares of Class A common stock on December 1, 2024 as all conversion conditions have been satisfied as of September 30, 2024. We define free cash flow as net cash used in operating activities less capital expenditures. The increase in year-over-year capital expenditures discussed above resulted in negative free cash flow¹ of $(1,153) million for the third quarter of 2024 as compared to $(1,067) million for the same period last year.
Webcast	We will host an audio webcast to discuss our results and provide a business update at 2:00pm PT / 5:00pm ET on Thursday, November 7th, 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 fair value gain or loss 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 fair value gain or loss 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.
