Estimated Preliminary Results as of and for the Three Months Ended September 30, 2023

Set forth below are certain preliminary and unaudited estimates of selected financial information as of and for the three months ended September 30, 2023. The unaudited selected financial information as of and for the three months ended September 30, 2023 reflects our preliminary estimates with respect to such results based on currently available information and is subject to completion of our financial closing procedures. Our financial closing procedures for the three months ended September 30, 2023 are not yet complete and, as a result, our actual results may vary from the estimated preliminary results presented here and will not be finalized until after the completion of this offering.

These estimates should not be viewed as a substitute for our full interim or annual financial statements prepared in accordance with U.S. generally accepted accounting practices (“U.S. GAAP”). Further, our preliminary estimated results are not necessarily indicative of the results to be expected for any future period as a result of various factors, including, but not limited to, those discussed in the sections titled “Risk Factors” and “Cautionary Note Regarding Forward-Looking Statements.” This information should be read in conjunction with “Management’s Discussion and Analysis of Financial Condition and Results of Operations” for prior periods incorporated by reference into this offering memorandum.

The preliminary estimates presented below have been prepared by, and are the responsibility of, management. KPMG LLP, our independent registered public accounting firm, has not audited, reviewed, compiled, or performed any procedures with respect to the preliminary financial information. Accordingly, KPMG LLP does not express an opinion or any other form of assurance with respect thereto.

The following table provides our preliminary estimates of revenue for the three months ended September 30, 2023:

We expect revenue to increase for the three months ended September 30, 2023 as compared to the three months ended September 30, 2022, primarily due to an increase in deliveries of vehicles during the three months ended September 30, 2023.

The following table provides our preliminary estimate of cash, cash equivalents and short-term investments as of September 30, 2023, compared to June 30, 2023:

We believe our existing cash, cash equivalents and short-term investments (without giving effect to this offering or the use of proceeds thereof) will be sufficient to enable us to fund our operations and capital expenditures through 2025. The foregoing is based on assumptions which may prove to be incorrect, and we could use our available capital resources sooner than we currently expect. This estimate is also based on current intentions, plans and business conditions, which could change in the future as our plans and business conditions evolve.

Rivian Automotive, Inc. Announces Proposed Green Convertible Senior Notes Offering

IRVINE, Calif.—(BUSINESS WIRE)—October 4, 2023—Rivian Automotive, Inc. (Nasdaq: RIVN) (“Rivian”) today announced its intention to offer, subject to market and other conditions, $1,500,000,000 aggregate principal amount of green convertible senior notes due 2030 (the “notes”) in a private offering to qualified institutional buyers pursuant to Rule 144A under the Securities Act of 1933, as amended (the “Securities Act”). Rivian also expects to grant the initial purchasers of the notes an option to purchase, for settlement within a period of 13 days from, and including, the date the notes are first issued, up to an additional $225,000,000 principal amount of notes.

The notes will be senior, unsecured obligations of Rivian, will accrue interest payable semi-annually in arrears and will mature on October 15, 2030, unless earlier repurchased, redeemed or converted. Noteholders will have the right to convert their notes in certain circumstances and during specified periods. Rivian will settle conversions by paying or delivering, as applicable, cash, shares of its Class A common stock (the “common stock”) or a combination of cash and shares of its common stock, at Rivian’s election.

The notes will be redeemable, in whole or in part (subject to certain limitations), for cash at Rivian’s option at any time, and from time to time, on or after October 20, 2027 and on or before the 20th scheduled trading day immediately before the maturity date, but only if the last reported sale price per share of Rivian’s common stock exceeds 130% of the conversion price for a specified period of time. The redemption price will be equal to the principal amount of the notes to be redeemed, plus accrued and unpaid interest, if any, to, but excluding, the redemption date.

If certain events that constitute a “fundamental change” occur, then, subject to limited exceptions, noteholders may require Rivian to repurchase their notes for cash. The repurchase price will be equal to the principal amount of the notes to be repurchased, plus accrued and unpaid interest, if any, to, but excluding, the applicable repurchase date.

The interest rate, initial conversion rate and other terms of the notes will be determined at the pricing of the offering.

Rivian intends to allocate an amount equal to the net proceeds from the offering to finance, refinance, make direct investments in, in whole or in part, one or more new or recently completed (within the 24 months prior to the issue date of the notes), current and/or future eligible projects (such projects, “Eligible Green Projects”), in alignment with the guidelines of the Green Bond Principles, 2021. Eligible Green Projects include expenditures relating to, investments in, financings of and/or acquisitions of one or more of the following: (i) clean transportation, (ii) renewable energy, (iii) circular economy, (iv) energy efficiency and (v) pollution prevention and control. Pending full allocation of an amount equal to the net proceeds from the offering to Eligible Green Projects, Rivian may temporarily invest the remainder of the net proceeds from the offering in cash, cash equivalents, and/or high-quality marketable securities, and will not knowingly invest in operations that result in an overall net increase in greenhouse gas emissions.

In connection with the pricing of the notes, Rivian expects to enter into privately negotiated capped call transactions with one or more of the initial purchasers or their affiliates and/or other financial institutions (the “option counterparties”). The capped call transactions are expected to cover, subject to customary adjustments, the number of shares of Rivian’s common stock that will initially underlie the notes. If the initial purchasers exercise their option to purchase additional notes, Rivian expects to enter into additional capped call transactions with the option counterparties. Rivian intends to use cash on hand to fund the cost of entering into the capped call transactions, including any additional capped call transactions.

The capped call transactions are expected generally to reduce the potential dilution to Rivian’s common stock upon any conversion of the notes and/or at Rivian’s election (subject to certain conditions) offset any potential cash payments Rivian is required to make in excess of the principal amount of converted notes, as the case may be, upon conversion of the notes. If, however, the market price per share of Rivian’s common stock, as measured under the terms of the capped call transactions, exceeds the cap price of the capped call transactions, there would nevertheless be dilution and/or there would not be an offset of such potential cash payments, in each case, to the extent that such market price exceeds the cap price of the capped call transactions.

In connection with establishing their initial hedges of the capped call transactions, the option counterparties or their respective affiliates expect to enter into various derivative transactions with respect to Rivian’s common stock and/or purchase shares of Rivian’s common stock concurrently with or shortly after the pricing of the notes. This activity could increase (or reduce the size of any decrease in) the market price of Rivian’s common stock or the notes at that time.

In addition, the option counterparties or their respective affiliates may modify their hedge positions by entering into or unwinding various derivatives with respect to Rivian’s common stock and/or purchasing or selling Rivian’s common stock or other securities in secondary market transactions following the pricing of the notes and prior to the maturity of the notes (and are likely to do so on each exercise date of the capped call transactions, which are expected to occur during the 20 trading day period beginning on the 21st scheduled trading day prior to the maturity date of the notes, or following our election to terminate any portion of the capped call transactions in connection with any repurchase, redemption, exchange or early conversion of the notes). This activity could also cause or avoid an increase or decrease in the market price of Rivian’s common stock or the notes, which could affect the ability to convert the notes, and, to the extent the activity occurs during any observation period related to a conversion of notes, it could affect the number of shares and value of the consideration that noteholders will receive upon conversion of the notes.

The offer and sale of the notes and any shares of common stock issuable upon conversion of the notes have not been, and will not be, registered under the Securities Act or any other securities laws, and the notes and any such shares cannot be offered or sold except pursuant to an exemption from, or in a transaction not subject to, the registration requirements of the Securities Act and any other applicable securities laws. This press release does not constitute an offer to sell, or the solicitation of an offer to buy, the notes or any shares of common stock issuable upon conversion of the notes, nor will there be any sale of the notes or any such shares, in any state or other jurisdiction in which such offer, sale or solicitation would be unlawful.
