ABOUT THIS PROSPECTUS SUPPLEMENT

This document is in two parts. The first part is this prospectus supplement, which describes the specific terms of this offering of common stock and also adds to and updates information contained in the accompanying prospectus and the documents incorporated by reference into this prospectus supplement and the accompanying prospectus. The second part is the accompanying prospectus dated October 24, 2024, included in our registration statement on Form S-3 (File No. 333-282809), along with the documents incorporated by reference therein, which provides more general information, some of which may not apply to this offering. Generally, when we refer to this prospectus, we are referring to both parts of this document combined. To the extent there is a conflict between the information contained in this prospectus supplement, on the one hand, and the information contained in the accompanying prospectus or in any document incorporated by reference that was filed with the Securities and Exchange Commission (the "SEC") before the date of this prospectus supplement, on the other hand, you should rely on the information contained in this prospectus supplement. If any statement in one of these documents is inconsistent with a statement in another document having a later date-for example, a document incorporated by reference in the accompanying prospectus-the statement in the document having the later date modifies or supersedes the earlier statement.

This prospectus supplement and the accompanying prospectus are part of a "shelf" registration statement that we filed with the SEC. Under this shelf registration process, we may offer from time to time various securities, of which this offering of shares of our common stock is a part. Such registration statement also includes exhibits that provide more detail on the matters discussed in this prospectus supplement and the accompanying prospectus. You should read this prospectus supplement, the accompanying prospectus, including the information incorporated by reference herein and therein, and the exhibits filed with the SEC in their entirety before making an investment decision.

We have not, and the underwriters have not, authorized anyone to provide you with information, or to make any representation, different from that contained or incorporated by reference in this prospectus supplement and the accompanying prospectus. We and the underwriters take no responsibility for, and can provide no assurance as to the reliability of, any other information that others may give you. You should assume that the information appearing in this prospectus supplement, the accompanying prospectus, the documents incorporated by reference in this prospectus supplement and the accompanying prospectus is accurate only as of the respective dates of those documents, unless we indicate otherwise. Our business, financial condition, results of operations and prospects may have changed since those dates.

We further note that the representations, warranties and covenants made by us in any agreement that is filed as an exhibit to any document that is incorporated by reference in this prospectus supplement or the accompanying prospectus were made solely for the benefit of the parties to such agreement, including, in some cases, for the purpose of allocating risk among the parties to such agreements, and should not be deemed to be a representation, warranty or covenant to you. Moreover, such representations, warranties and covenants were accurate only as of the date when made; therefore, such representations, warranties and covenants should not be relied on as accurate representations of the current state of our affairs.

We are not, and the underwriters are not, making an offer to sell our common stock in any jurisdiction where the offer or sale is not permitted. Neither this prospectus supplement nor the accompanying prospectus constitute, and may not be used in connection with, an offer to sell, or a solicitation of an offer to buy, any securities offered by this prospectus supplement by any person in any jurisdiction in which it is unlawful for such person to make such an offer or solicitation. You must comply with all applicable laws and regulations in force in any applicable jurisdiction and you must obtain any consent, approval or permission required by you for the purchase, offer or sale of the common stock under the laws and regulations in force in the jurisdiction to which you are subject or in which you make your purchase, offer or sale, and neither we nor the underwriters will have any responsibility therefor.

PROSPECTUS SUPPLEMENT SUMMARY

This summary highlights certain information about us, this offering and selected information contained elsewhere in or incorporated by reference into this prospectus supplement or the accompanying prospectus. This summary is not complete and does not contain all of the information that you should consider before deciding whether to invest in our common stock. For a more complete understanding of our company and this offering, we encourage you to read and consider carefully the more detailed information in this prospectus supplement and the accompanying prospectus, including the information incorporated by herein and therein, which are described under the heading "Where You Can Find More Information; Incorporation by Reference" in this prospectus supplement. You should also carefully consider the matters discussed in the sections in this prospectus supplement and in the accompanying prospectus titled "Risk Factors" and the other information that we incorporate by reference into this prospectus supplement, including the section titled "Risk Factors" in our Annual Report on Form 10-K for the year ended December 31, 2023.

Overview

We have spent more than a decade designing and testing a piloted all-electric, vertical take-off and landing ("eVTOL") aircraft that we intend to operate in cities around the world. Our mission is to help the world connect faster and more easily with the people and places that matter most by delivering a new form of clean, fast, quiet and convenient aerial transportation service. The Joby eVTOL is designed to transport a pilot and four passengers at speeds of up to 200 mph with a range optimized for urban markets of up to 100 miles on a single charge, and is expected to have a 1,000 pound payload. According to our modeling, more than 99% of urban routes in cities such as New York City and Los Angeles are significantly shorter than this, enabling higher utilization through faster turnaround times of our aircraft. By combining the freedom of air travel with the efficiency of our aircraft, we expect to deliver journeys that are up to 10 times faster than driving, and it is our goal to steadily drive down end-user pricing in the years following commercial launch to make the service widely accessible.

Our aircraft has been specifically designed with multiple redundancies across systems and components for enhanced safety and to achieve a considerably lower noise footprint than that of similarly sized conventional aircraft or helicopters. We believe the low noise enabled by the all-electric powertrain will allow the aircraft to operate around dense, urban areas while blending into the background noise of cities. The aircraft is quiet at takeoff and near silent when flying overhead, which we anticipate will allow us to operate from new skyport locations nearer to where people live and work, in addition to utilizing the more than 5,000 heliport and airport infrastructure facilities already in existence in the U.S.

We are in the process of certifying our aircraft with the U.S. Federal Aviation Administration ("FAA"). This involves a rigorous process of design, testing, verification and quality control. We think of the FAA type certification process in five stages and have made significant progress towards certification. We have completed or substantially completed three of these five stages. With more than 1,000 successful test flights already completed, and as the first eVTOL aircraft developer to receive a signed, stage 4 G-1 certification basis which was subsequently published in final form in the Federal Register, we believe we are well positioned to be the first eVTOL manufacturer to earn airworthiness certification from the FAA. We have also begun working with regulators in other countries, including the United Kingdom, Japan, South Korea and the United Arab Emirates ("UAE") to pursue commercialization opportunities in those markets. While foreign certification in many countries leverages our work with the FAA, in some, such as the UAE, it may also provide a path to commercial operations prior to receiving certification in the United States.

We have flown more than 30,000 miles in our prototype aircraft. In November 2023, we completed our first urban flight exhibition at an event in New York City hosted by the New York City Economic Development Corporation, and attended by critical stakeholders such as the Port Authority of New York and New Jersey and elected officials.

We plan to manufacture, own and operate our aircraft, building a vertically integrated transportation company that will deliver transportation services to our customers, including government agencies, such as the U.S. Air Force ("USAF"), through sales or contracted operations, and to individual end-users through a convenient app-based aerial

ridesharing service. We delivered our first aircraft for initial service operations with the U.S. Department of Defense ("DOD") in September 2023 and are targeting initial commercial passenger operations as early as the end of 2025. We believe this vertically-integrated business model will generate the greatest economic returns, while providing us with end-to-end control over the customer experience to optimize for customer safety, comfort and value. While selling aircraft is not our primary business model, there may be circumstances in which it is either required (for example, due to operating restrictions on foreign ownership in other countries) or otherwise desirable to sell aircraft in the future. We do not expect this would change our core focus on building a vertically integrated transportation company.

We operate a powertrain and electronics engineering and manufacturing facility in San Carlos, California, as well as 130,000 square feet of additive and subtractive manufacturing, machining, aircraft assembly and flight test facilities in Marina, California. These facilities are utilized to design, build and test the components, systems and assemblies for our aircraft as we refine our design and hone our production process. We believe that our California operations will both be able to support our initial low-rate production plans as well as serve as a testing and development facility for future innovations. Our high-rate production facility is planned for Dayton, Ohio where we have identified a 140-acre site that has the potential to support significant growth over time, with enough land to build over two million square feet of manufacturing space. We expect to have the capacity to manufacture up to one aircraft per month by the end of 2024, and at scale, we aim to produce up to 500 aircraft per year. With strong financial incentives and support from state and local governments, we look forward to expanding our manufacturing in the birthplace of aviation as our business grows.

Our preparations for commercial passenger service include forming sector-leading relationships with partners such as Toyota, Uber, Delta Air Lines, and SK Telecom in South Korea, all of whom have invested in Joby, as well as global partners such as ANA Airlines in Japan and the Road and Transport Authority in Dubai. We have also established relationships with infrastructure providers, including fixed base operators of landing sites, such as Atlantic Aviation, Helo Holdings, Inc. ("HHI") and Skyports, to facilitate infrastructure development in key markets. Additionally, we have long-standing relationships in research and development with federal government agencies as we evolved our design for the fastest, quietest eVTOL in its class.

Announcement of Toyota's $500 Million Incremental Investment to Further Support Certification and Production

On October 1, 2024, we entered into a stock purchase agreement (the "Stock Purchase Agreement") with Toyota Motor Corporation ("Toyota"), providing for the issuance and sale of up to an aggregate of 99,403,579 shares of our common stock to Toyota, at a purchase price of $5.03 per share, in a private placement upon the terms and conditions set forth in the Stock Purchase Agreement (the "Toyota Investment").

The Toyota Investment is structured in two equal tranches of $250.0 million each. The closing of each tranche is subject to the satisfaction of certain closing conditions set forth in the Stock Purchase Agreement. The first tranche is subject to conditions including, but not limited to: (i) the satisfaction of certain regulatory approvals or clearances, including with respect to the Committee on Foreign Investment in the United States and under the United States Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, and the rules and regulations promulgated thereunder; (ii) the adoption of certain changes to the provisions of our amended and restated bylaws concerning the ownership of common stock by non-citizens of the United States (the "Foreign Ownership Requirement"); (iii) the authorization by our board of directors of certain changes to Article XIV of our amended and restated certificate of incorporation concerning the Foreign Ownership Requirement (the "Charter Amendment"), subject to approval by our stockholders at our annual meeting in 2025; (iv) the execution of an amendment and restatement of the Amended and Restated Collaboration Agreement, dated August 30, 2019, between us and Toyota; (v) the execution of a services agreement by us and Toyota; and (vi) certain other customary closing conditions.

conditions are subject to the receipt of regulatory approvals, us and Toyota negotiating and entering into definitive agreements and the conditions included within the applicable definitive documents.

We intend to use the net proceeds from the Toyota Investment for working capital and general corporate purposes to support our certification efforts and commercial production of its electric air taxi.

We are subject to a number of obligations in the Stock Purchase Agreement, including, among others, covenants regarding the conduct of and carrying on of our business, and certain limitations with respect to the use of the proceeds from the sale of the shares in the Toyota Investment. The Stock Purchase Agreement contains customary representations, warranties and agreements by us, indemnification obligations of us and Toyota for liabilities under the Securities Act of 1933, as amended (the "Securities Act"), and other obligations of the parties.

Toyota has certain demand registration rights and piggyback registration rights pursuant to the terms of the Stock Purchase Agreement.

Please see "Risk Factors-Risks Related to this Offering-The Toyota Investment is subject to closing conditions, including conditions beyond our control, and no assurance can be given that closing will take place on the timeline currently anticipated or at all. Any failure to close one or both of the tranches of the Toyota Investment could adversely impact our future liquidity and our financial condition" or our Current Report on Form 8-K filed with the SEC on October 2, 2024 for more information.

RISK FACTORS

Investing in our common stock involves risk. Before deciding whether to invest in our common stock, you should consider carefully the risks and uncertainties described below. You should also consider the risks, uncertainties and assumptions discussed under the heading "Risk Factors" included in our Annual Report on Form 10-K for the year ended December 31, 2023, which is incorporated herein by reference, and which may be amended, supplemented or superseded from time to time by other reports we file with the SEC in the future. There may be other unknown or unpredictable economic, business, competitive, regulatory or other factors that could have material adverse effects on our future results. If any of these risks actually occurs, our business, business prospects, financial condition or results of operations could be seriously harmed. This could cause the trading price of our common stock to decline, resulting in a loss of all or part of your investment. Please also read carefully the section titled "Special Note Regarding Forward-Looking Statements."

Risks Related to This Offering

Our management team may invest or spend the proceeds of this offering in ways with which you may not agree or in ways which may not yield a significant return.

Our management will have broad discretion over the use of proceeds from this offering. We currently intend to use the net proceeds from this offering, together with our existing cash, cash equivalents and short-term in, to fund our certification and manufacturing efforts, prepare for commercial operations and for general working capital and other general corporate purposes. Our management will have considerable discretion in the application of the net proceeds, and you will not have the opportunity, as part of your investment decision, to assess whether the proceeds are being used appropriately. The net proceeds may be used for corporate purposes that do not improve our results of operations or enhance the value of our common stock.

Purchasers of shares of our common stock in this offering will experience immediate and substantial dilution in the book value of their investment and may experience further dilution as a result of shares that we may issue in connection with the Toyota Investment.

The public offering price of our common stock is substantially higher than the as adjusted net tangible book value per share of our common stock. Therefore, if you purchase our common stock in this offering, you will pay a price per share that substantially exceeds the as adjusted net tangible book value per share after the completion of this offering. Based on the public offering price of $5.05 per share, you will experience immediate dilution of $3.72 per share (or $3.69 per share if the underwriters exercise their option to purchase additional shares in full), representing the difference between our as adjusted net tangible book value per share as of June 30, 2024 and the public offering price. Furthermore, if the underwriters exercise their option to purchase additional shares. if outstanding options or warrants are exercised or additional RSUs vest and settle, or if we issue shares of common stock in connection with the Toyota Investment, you could experience further dilution. We anticipate issuing up to 99,403,579 shares of common stock in connection with the Toyota Investment at a purchase price of $5.03 per share. See the risk factor titled "The Toyota Investment is subject to closing conditions and no assurance can be given that closing will take place on the timeline currently anticipated or at all. Any failure to close one or both of the tranches of the Toyota Investment could adversely impact our future liquidity and our financial condition." See the section titled "Dilution" for a more detailed description of the dilution to new investors participating in this offering.

You may experience future dilution as a result of future equity offerings.

In order to raise additional capital, we expect to offer additional shares of our common stock or other securities convertible into or exchangeable for our common stock in the future. We cannot assure you that we will be able to sell shares or other securities in any other offering at a price per share that is equal to or greater than the price per share paid by investors in this offering, and investors purchasing shares or other securities in the future could have rights superior to existing stockholders. The price per share at which we sell additional shares of our common stock or other securities convertible into or exchangeable for our common stock in future transactions may be higher or lower than the price per share in this offering.

S-6

Table of Contents

The sale of our common stock in this offering and any future sales of our common stock, or the perception that such sales could occur, may depress our stock price and our ability to raise funds in new stock offerings.

The market price of our common stock could decline as a result of sales of a large number of shares of our common stock in the public market. The perception that these sales might occur, including sales by us, our executive officers and directors or our significant stockholders, may also cause the market price of our common stock to decline.

We and our executive officers and directors have entered into lock-up agreements with the underwriters under which we and they have agreed, subject to specific exceptions described in the section titled "Underwriters," not to sell, directly or indirectly, any of our equity securities without the permission of Morgan Stanley & Co. LLC, as representative of the underwriters of this offering, for a period of 90 days following the date of this prospectus supplement. When this lock-up period expires, we and our securityholders subject to a lock-up agreement could sell shares in the public market, which could cause our stock price to fall. Morgan Stanley & Co. LLC may, in its sole discretion, permit the persons who are subject to these lock-up agreements to sell shares prior to the expiration of the lock-up agreements. See the section titled "Underwriters" for a description of the lock-up agreements with the underwriters of this offering. Sales of a substantial number of such shares upon expiration of the lock-up agreements, the perception that such sales may occur or early release of these agreements, could cause our market price to fall or make it more difficult for you to sell your common stock at a time and price that you deem appropriate.

In addition, certain of our stockholders are contractually restricted from selling or transferring shares of common stock (the "Lock-up Shares") for an agreed-upon period of time. For example, certain significant stockholders have agreed to a five-year lockup, which began in 2021, with 20% of the Lock-up Shares being released on each anniversary of the closing of the Merger (as defined in the accompanying prospectus), subject to a complete release of the Lock-Up Shares if we undergo a change of control (the "Major Company Equityholders Lock-Up Agreement"). Under the Sponsor Agreement (as defined in the accompanying prospectus), by and among us, Reinvent Sponsor, LLC ("Sponsor") and Reinvent Technology Partners, the Sponsor's Lock-up Shares are subject to the same releases agreed to in the Major Company Equityholders' Lock-Up Agreement in addition to vesting conditions. Following the expiration of each lock-up tranche, the applicable stockholders will no longer be restricted from selling shares of our common stock held by them, other than by applicable securities laws. As such, sales of a substantial number of shares of our common stock in the public market could occur at any time. These sales, or the perception in the market that the holders of a large number of shares intend to sell their shares, could reduce the market price of our common stock. As of September 30, 2024, there were approximately 151,890,585 shares subject to the Major Company Equityholders Lock-Up Agreement. As restrictions on resale end, the sale or possibility of sale of these shares could have the effect of increasing the volatility in our share price or the market price of our common stock could decline if the holders of currently restricted shares sell them or are perceived by the market as intending to sell them.

Further, shares issued upon the exercise of outstanding warrants or upon the exercise or settlement of outstanding awards under our equity incentive plans, or pursuant to future awards granted under those plans, will become available for sale in the public market to the extent permitted by the provisions of applicable vesting schedules and applicable law.

Moreover, certain holders of a substantial number of shares of our common stock have rights, subject to conditions, to require us to file registration statements covering their shares or to include their shares in registration statements that we may file for ourselves or other stockholders.

The Toyota Investment is subject to closing conditions, including conditions beyond our control, and no assurance can be given that closing will take place on the timeline currently anticipated or at all. Any failure to close one or both of the tranches of the Toyota Investment could adversely impact our future liquidity and our financial condition.

On October 1, 2024, we entered into the Stock Purchase Agreement with Toyota providing for the potential issuance and sale of up to an aggregate of 99,403,579 shares of our common stock to Toyota. The Toyota

Investment is structured in two equal tranches of $250.0 million each. The closing of each tranche is subject to the satisfaction of certain closing conditions set forth in the Stock Purchase Agreement. The first tranche is subject to conditions including, but not limited to: (i) the satisfaction of certain regulatory approvals or clearances, including with respect to the Committee on Foreign Investment in the United States and under the United States Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, and the rules and regulations promulgated thereunder; (ii) the Foreign Ownership Requirement; (iii) the authorization by our board of directors of the Charter Amendment, subject to approval by our stockholders at our annual meeting in 2025; (iv) the execution of an amendment and restatement of the Amended and Restated Collaboration Agreement, dated August 30, 2019, between us and Toyota; (v) the execution of a services agreement by us and Toyota; and (vi) certain other customary closing conditions. The Additional Closing is subject to conditions including, but not limited to: (i) the execution of a strategic alliance agreement relating to, among other things, manufacturing arrangements, by us and Toyota; (ii) the approval of the Charter Amendment by our stockholders at our annual meeting in 2025; and (iii) certain other customary closing conditions. The agreements to be entered into in connection with such conditions are subject to the receipt of regulatory approvals, the parties negotiating and entering into definitive agreements and the conditions included within the applicable definitive documents.

We may experience delays and difficulties in satisfying the conditions for closing on either or both of the tranches of the Toyota Investment, and no assurance can be given that closing will take place on the timeline currently anticipated or at all. Some of the conditions to closing are outside of our control and it is possible that not all of the closing conditions to the Toyota Investment will be satisfied or that we will not receive the entire amount of expected proceeds on the timeline currently anticipated or at all. For example, the Toyota Investment is subject to, among others, certain regulatory approvals and clearances and the approval of the Charter Amendment by our stockholders at our annual meeting in 2025. In addition, certain closing conditions require us and Toyota to successfully negotiate and enter into definitive agreements. The final terms of such definitive agreements are not yet established and the negotiation and execution of such agreements may take longer than expected or may not be possible to accomplish on terms acceptable to us, or at all. No assurance can be given that any agreement we may reach will achieve our goals or be on terms that prove to be economically or strategically beneficial to us. Such adverse developments, including any failure to close one or both of the tranches of the Toyota Investment, could adversely impact our business, financial condition, results of operations and liquidity.

You should not rely upon forward-looking statements as predictions of future events. We have based the forward-looking statements contained or incorporated by reference in this prospectus supplement primarily on our current expectations and projections about future events and trends that we believe may affect our business, financial condition, results of operations and prospects.

Moreover, we operate in a very competitive and rapidly changing environment. New risks and uncertainties emerge from time to time and it is not possible for us to predict all risks and uncertainties or the extent to which any factor or combination of factors may cause actual results to differ materially from those contained in any forward-looking statements we may make in this prospectus supplement or the documents incorporated by reference herein. We cannot assure you that the results, events and circumstances reflected in the forward-looking statements will be achieved or occur. Actual results, events or circumstances could differ materially and adversely from those described or anticipated in the forward-looking statements.

We may not actually achieve the plans, intentions or expectations disclosed in our forward-looking statements and you should not place undue reliance on our forward-looking statements.

Our actual results and timing of selected events may differ materially from those anticipated in these forward-looking statements as a result of many factors, including those described in, or incorporated by reference into, the section titled "Risk Factors" and elsewhere in this prospectus supplement.

USE OF PROCEEDS

We estimate that the net proceeds to us from this offering will be approximately $192.8 million, after deducting the underwriting discounts and commissions and estimated offering expenses payable by us. If the underwriters exercise their option to purchase additional shares in full, we estimate that our net proceeds will be approximately $221.8 million, after deducting the underwriting discounts and commissions and estimated offering expenses payable by us.

We currently intend to use the net proceeds from this offering, together with our existing cash, cash equivalents and short-term investments to fund our certification and manufacturing efforts, prepare for commercial operations and for general working capital and other general corporate purposes.

Our expected uses of the net proceeds from this offering represent our intentions based on our present plans and business conditions. The amounts and timing of our actual expenditures will depend on numerous factors, including our progress against certification and manufacturing milestones, the speed at which we grow our workforce, the timing of capital expenditures related to our planned manufacturing operations, as well as the amount of cash used in our operations and the actual and anticipated growth of our business. We therefore cannot estimate with certainty the amount of net proceeds to be used for the purposes described above. We may find it necessary or advisable to use the net proceeds for other purposes, and we will have broad discretion in the application of the net proceeds.

Pending the uses described above, we intend to invest the net proceeds from this offering in short-term, investment-grade, interest-bearing securities such as money market accounts, certificates of deposit, commercial paper and guaranteed obligations of the U.S. government.

DIVIDEND POLICY

We have never declared or paid, and do not anticipate declaring or paying in the foreseeable future, any dividends on our capital stock. Any future determination as to the declaration and payment of dividends, if any, will be at the discretion of our board of directors, subject to applicable laws and will depend on then-existing conditions, including our financial condition, results of operations, capital requirements, contractual restrictions, such as those that are included in current agreements or that may be contained in future agreements and financing instruments, business prospects and other factors our board of directors may deem relevant.

DILUTION

If you invest in our common stock in this offering, your ownership interest will be immediately diluted to the extent of the difference between the public offering price per share of our common stock in this offering and the net tangible book value per share of our common stock after this offering.

Our net tangible book value as of June 30, 2024 was $809.7 million, or $1.13 per share. Net tangible book value per share is determined by dividing our total tangible assets, less total liabilities, by the number of shares of our common stock outstanding as of June 30, 2024. Dilution in net tangible book value per share represents the difference between the amount per share paid by purchasers of shares of common stock in this offering and the as adjusted net tangible book value per share of our common stock immediately after giving effect to this offering.

After giving effect to the sale of shares of common stock in this offering by us at the public offering price of $5.05 per share, and after deducting the underwriting discounts and commissions and estimated offering expenses payable by us, our as adjusted net tangible book value as of June 30, 2024 would have been $1.0 billion, or $1.33 per share. This represents an immediate increase in net tangible book value of $0.20 per share to existing stockholders and an immediate dilution of $3.72 per share to investors participating in this offering, as illustrated in the following table:


Public offering price per share	$	5.05
Net tangible book value per share as of June 30, 2024	$	1.13
Increase in net tangible book value per share attributable to this offering	$	0.20
As adjusted net tangible book value per share after giving effect to this offering	$	1.33
Dilution in net tangible book value per share to new investors participating in this offering	$	3.72

If the underwriters exercise in full their option to purchase additional shares, as adjusted net tangible book value after this offering would increase to $1.36 per share, and there would be an immediate dilution of $3.69 per share to new investors.

Upon the vesting and settlement of outstanding RSUs, and to the extent that outstanding options or warrants are exercised, or if we issue shares of common stock in connection with the Toyota Investment, new investors will experience further dilution. We anticipate issuing up to 99,403,579 shares of common stock in connection with the Toyota Investment. In addition, we may choose to raise additional capital due to market conditions or strategic considerations even if we believe we have sufficient funds for our current or future operating plans. To the extent that we raise additional capital through the sale of equity or convertible debt securities, the issuance of these securities could result in further dilution to our stockholders.

The foregoing table and calculations exclude the following shares as of June 30, 2024:

•12,014,628 shares of common stock issuable upon the exercise of outstanding stock options having a weighted-average exercise price of $0.70 per share;

•43,863,217 shares of common stock issuable upon the vesting and settlement of outstanding RSUs;

•2,136,091 shares of common stock issuable upon the vesting and settlement of RSUs granted subsequent to June 30, 2024;

•86,311,618 shares of common stock reserved for issuance pursuant to future equity awards under our 2021 Incentive Award Plan as of June 30, 2024, as well as any future increases in the number of shares of our common stock reserved for future issuance under this plan;

MATERIAL U.S. FEDERAL INCOME TAX CONSEQUENCES TO NON-U.S. HOLDERS

The following discussion is a summary of the material U.S. federal income tax consequences to Non-U.S. Holders (as defined below) of the purchase, ownership and disposition of our common stock issued pursuant to this offering, but does not purport to be a complete analysis of all potential tax effects. The effects of other U.S. federal tax laws, such as estate and gift tax laws, and any applicable state, local or non-U.S. tax laws are not discussed. This discussion is based on the U.S. Internal Revenue Code of 1986, as amended (the "Code"), Treasury Regulations promulgated thereunder, judicial decisions and published rulings and administrative pronouncements of the U.S. Internal Revenue Service (the "IRS"), in each case in effect as of the date hereof. These authorities may change or be subject to differing interpretations. Any such change or differing interpretation may be applied retroactively in a manner that could adversely affect a Non-U.S. Holder. We have not sought and will not seek any rulings from the IRS regarding the matters discussed below. There can be no assurance the IRS or a court will not take a contrary position to that discussed below regarding the tax consequences of the purchase, ownership and disposition of our common stock.

This discussion is limited to Non-U.S. Holders that hold our common stock as a "capital asset" within the meaning of Section 1221 of the Code (generally, property held for investment). This discussion does not address all U.S. federal income tax consequences relevant to a Non-U.S. Holder's particular circumstances, including the impact of the Medicare contribution tax on net investment income and the alternative minimum tax. In addition, it does not address consequences relevant to Non-U.S. Holders subject to special rules, including, without limitation:

•U.S. expatriates and former citizens or long-term residents of the United States;

•persons holding our common stock as part of a hedge, straddle or other risk reduction strategy or as part of a conversion transaction or other integrated investment;

•banks, insurance companies and other financial institutions;

•brokers, dealers or traders in securities;

•"controlled foreign corporations," "passive foreign investment companies" and corporations that accumulate earnings to avoid U.S. federal income tax;

•partnerships or other entities or arrangements treated as partnerships for U.S. federal income tax purposes (and investors therein);

•tax-exempt organizations or governmental organizations;

•persons deemed to sell our common stock under the constructive sale provisions of the Code;

•persons who hold or receive our common stock pursuant to the exercise of any employee stock option or otherwise as compensation;

•tax-qualified retirement plans; and

•"qualified foreign pension funds" as defined in Section 897(l)(2) of the Code and entities all of the interests of which are held by qualified foreign pension funds.

If an entity treated as a partnership or other pass-through entity for U.S. federal income tax purposes holds our common stock, the tax treatment of a partner or beneficial owner in the partnership or other pass-through entity will depend on the status of the partner or beneficial owner, the activities of the partnership or other pass-through entity and certain determinations made at the partner or beneficial owner level. Accordingly, partnerships and other pass-through entities holding our common stock and the partners or beneficial owners in such partnerships or other pass-through entities should consult their tax advisors regarding the U.S. federal income tax consequences to them.

THIS DISCUSSION IS FOR INFORMATIONAL PURPOSES ONLY AND IS NOT TAX ADVICE. INVESTORS SHOULD CONSULT THEIR TAX ADVISORS WITH RESPECT TO THE APPLICATION OF THE U.S. FEDERAL INCOME TAX LAWS TO THEIR PARTICULAR SITUATIONS AS WELL AS ANY TAX CONSEQUENCES OF THE PURCHASE, OWNERSHIP AND DISPOSITION OF OUR COMMON STOCK ARISING UNDER THE U.S. FEDERAL ESTATE OR GIFT TAX LAWS OR UNDER THE LAWS OF ANY STATE, LOCAL OR NON-U.S. TAXING JURISDICTION OR UNDER ANY APPLICABLE INCOME TAX TREATY.

Definition of a Non-U.S. Holder

For purposes of this discussion, a "Non-U.S. Holder" is any beneficial owner of our common stock that is neither a "United States person" nor an entity treated as a partnership or other pass-through entity for U.S. federal income tax purposes. A United States person is any person that, for U.S. federal income tax purposes, is or is treated as any of the following:

•an individual who is a citizen or resident of the United States;

•a corporation created or organized under the laws of the United States, any state thereof or the District of Columbia;

•an estate, the income of which is subject to U.S. federal income tax regardless of its source; or

•a trust that (1) is subject to the primary supervision of a U.S. court and all substantial decisions of which are subject to the control of one or more United States persons, or (2) has a valid election in effect to be treated as a United States person for U.S. federal income tax purposes.

Distributions

As described in the section titled "Dividend Policy," we have never declared or paid, and do not anticipate declaring or paying in the foreseeable future, any dividends on our common stock. However, if we do make distributions of cash or property on our common stock, such distributions will constitute dividends for U.S. federal income tax purposes to the extent paid from our current or accumulated earnings and profits, as determined under U.S. federal income tax principles. Amounts not treated as dividends for U.S. federal income tax purposes will constitute a return of capital and first be applied against and reduce a Non-U.S. Holder's adjusted tax basis in its common stock, but not below zero. Any excess will be treated as capital gain and will be treated as described below under "-Sale or Other Taxable Disposition."

Subject to the discussion below regarding effectively connected income, dividends paid to a Non-U.S. Holder will be subject to U.S. federal withholding tax at a rate of 30% of the gross amount of the dividends (or such lower rate specified by an applicable income tax treaty, provided the Non-U.S. Holder furnishes a valid IRS Form W-8BEN or W-8BEN-E (or other applicable documentation) certifying qualification for the lower treaty rate). A Non-U.S. Holder that does not timely furnish the required documentation, but that qualifies for a reduced treaty rate, may obtain a refund of any excess amounts withheld by timely filing an appropriate claim for refund with the IRS. Non-U.S. Holders should consult their tax advisors regarding their entitlement to benefits under any applicable tax treaties.

If dividends paid to a Non-U.S. Holder are effectively connected with the Non-U.S. Holder's conduct of a trade or business within the United States (and, if required by an applicable income tax treaty, the Non-U.S. Holder maintains a permanent establishment in the United States to which such dividends are attributable), the Non-U.S. Holder will be exempt from the U.S. federal withholding tax described above. To claim the exemption, the Non-U.S. Holder must furnish to the applicable withholding agent a valid IRS Form W-8ECI, certifying that the dividends are effectively connected with the Non-U.S. Holder's conduct of a trade or business within the United States.

Any such effectively connected dividends will be subject to U.S. federal income tax on a net income basis at the regular rates applicable to United States persons. A Non-U.S. Holder that is a corporation also may be subject to a branch profits tax at a rate of 30% (or such lower rate specified by an applicable income tax treaty) on such

S-15

Table of Contents

effectively connected dividends, as adjusted for certain items. Non-U.S. Holders should consult their tax advisors regarding any applicable tax treaties that may provide for different rules.

Sale or Other Taxable Disposition

Subject to the discussion below regarding backup withholding, a Non-U.S. Holder generally will not be subject to U.S. federal income or withholding tax on any gain realized upon the sale or other taxable disposition of our common stock unless:

•the gain is effectively connected with the Non-U.S. Holder's conduct of a trade or business within the United States (and, if required by an applicable income tax treaty, the Non-U.S. Holder maintains a permanent establishment in the United States to which such gain is attributable);

•the Non-U.S. Holder is a nonresident alien individual present in the United States for 183 days or more during the taxable year of the disposition and certain other requirements are met; or

•our common stock constitutes a U.S. real property interest (a "USRPI") by reason of our status as a U.S. real property holding corporation (a "USRPHC") for U.S. federal income tax purposes.

Gain described in the first bullet point above generally will be subject to U.S. federal income tax on a net income basis at the regular rates applicable to United States persons. A Non-U.S. Holder that is a corporation also may be subject to a branch profits tax at a rate of 30% (or such lower rate specified by an applicable income tax treaty) on such effectively connected gain, as adjusted for certain items.

A Non-U.S. Holder described in the second bullet point above will be subject to U.S. federal income tax at a rate of 30% (or such lower rate specified by an applicable income tax treaty) on gain realized upon the sale or other taxable disposition of our common stock, which may be offset by certain U.S.-source capital losses of the Non-U.S. Holder (even though the individual is not considered a resident of the United States), provided the Non-U.S. Holder has timely filed U.S. federal income tax returns with respect to such losses.

With respect to the third bullet point above, we believe we currently are not, and do not anticipate becoming, a USRPHC. Because the determination of whether we are a USRPHC depends, however, on the fair market value of our USRPIs relative to the fair market value of our non-USRPIs and our other business assets, there can be no assurance we currently are not a USRPHC or will not become one in the future. Even if we are or were to become a USRPHC, gain arising from the sale or other taxable disposition of our common stock by a Non-U.S. Holder will not be subject to U.S. federal income tax if our common stock is "regularly traded," as defined by applicable Treasury Regulations, on an established securities market, and such Non-U.S. Holder owned, actually and constructively, 5% or less of our common stock throughout the shorter of the five-year period ending on the date of the sale or other taxable disposition or the Non-U.S. Holder's holding period.

Non-U.S. Holders should consult their tax advisors regarding any applicable tax treaties that may provide for different rules.

Information Reporting and Backup Withholding

Payments of dividends on our common stock will not be subject to backup withholding, provided the Non-U.S. Holder certifies its non-U.S. status, such as by furnishing a valid IRS Form W-8BEN, W-8BEN-E or W-8ECI, or otherwise establishes an exemption. However, information returns are required to be filed with the IRS in connection with any distributions on our common stock paid to the Non-U.S. Holder, regardless of whether such distributions constitute dividends or whether any tax was actually withheld. In addition, proceeds of the sale or other taxable disposition of our common stock within the United States or conducted through certain U.S.-related brokers generally will not be subject to backup withholding or information reporting if the applicable withholding agent receives the certification described above or the Non-U.S. Holder otherwise establishes an exemption. Proceeds of a disposition of our common stock conducted through a non-U.S. office of a non-U.S. broker that does not have certain enumerated relationships with the United States generally will not be subject to backup withholding or information reporting.

S-16

Table of Contents

Copies of information returns that are filed with the IRS may also be made available under the provisions of an applicable treaty or agreement to the tax authorities of the country in which the Non-U.S. Holder resides or is established.

Backup withholding is not an additional tax. Any amounts withheld under the backup withholding rules may be allowed as a refund or a credit against a Non-U.S. Holder's U.S. federal income tax liability, provided the required information is timely furnished to the IRS.

Additional Withholding Tax on Payments Made to Foreign Accounts

Withholding taxes may be imposed under Sections 1471 to 1474 of the Code (such Sections commonly referred to as the Foreign Account Tax Compliance Act ("FATCA")) on certain types of payments made to non-U.S. financial institutions and certain other non-U.S. entities. Specifically, a 30% withholding tax may be imposed on dividends on, or, subject to the proposed Treasury Regulations discussed below, gross proceeds from the sale or other disposition of, our common stock paid to a "foreign financial institution" or a "non-financial foreign entity" (each as defined in the Code), unless (1) the foreign financial institution undertakes certain diligence and reporting obligations, (2) the non-financial foreign entity either certifies it does not have any "substantial United States owners" (as defined in the Code) or furnishes identifying information regarding each substantial United States owner or (3) the foreign financial institution or non-financial foreign entity otherwise qualifies for an exemption from these rules. If the payee is a foreign financial institution and is subject to the diligence and reporting requirements in (1) above, it must enter into an agreement with the U.S. Department of the Treasury requiring, among other things, that it undertake to identify accounts held by certain "specified United States persons" or "United States owned foreign entities" (each as defined in the Code), annually report certain information about such accounts, and withhold 30% on certain payments to non-compliant foreign financial institutions and certain other account holders. Foreign financial institutions located in jurisdictions that have an intergovernmental agreement with the United States governing FATCA may be subject to different rules.

Under the applicable Treasury Regulations and administrative guidance, withholding under FATCA generally applies to payments of dividends on our common stock. While withholding under FATCA would have applied also to payments of gross proceeds from the sale or other disposition of our common stock on or after January 1, 2019, proposed Treasury Regulations eliminate FATCA withholding on payments of gross proceeds entirely. Taxpayers generally may rely on these proposed Treasury Regulations until final Treasury Regulations are issued.

Prospective investors should consult their tax advisors regarding the potential application of withholding under FATCA to their investment in our common stock.

UNDERWRITERS

Under the terms and subject to the conditions in an underwriting agreement dated the date of this prospectus supplement, the underwriters named below, for whom Morgan Stanley & Co. LLC and Allen & Company LLC are acting as representatives, have severally agreed to purchase, and we have agreed to sell to them, severally, the number of shares indicated below:


Name	Number of Shares
Morgan Stanley & Co. LLC	32,000,000
Allen & Company LLC	8,000,000
Total:	40,000,000

The underwriters and the representatives are collectively referred to as the "underwriters" and the "representatives," respectively. The underwriters are offering the shares of common stock subject to their acceptance of the shares from us and subject to prior sale. The underwriting agreement provides that the obligations of the several underwriters to pay for and accept delivery of the shares of common stock offered by this prospectus supplement are subject to the approval of certain legal matters by their counsel and to certain other conditions. The underwriters are obligated to take and pay for all of the shares of common stock offered by this prospectus supplement if any such shares are taken. However, the underwriters are not required to take or pay for the shares covered by the underwriters' option to purchase additional shares described below.

The underwriters initially propose to offer part of the shares of common stock directly to the public at the offering price listed on the cover page of this prospectus supplement and part to certain dealers at a price that represents a concession not in excess of $0.128775 per share under the public offering price. After the initial offering of the shares of common stock, the offering price and other selling terms may from time to time be varied by the representatives.

We have granted to the underwriters an option, exercisable for 30 days from the date of this prospectus supplement, to purchase up to 6,000,000 additional shares of common stock at the public offering price listed on the cover page of this prospectus supplement, less underwriting discounts and commissions. To the extent the option is exercised, each underwriter will become obligated, subject to certain conditions, to purchase about the same percentage of the additional shares of common stock as the number listed next to the underwriter's name in the preceding table bears to the total number of shares of common stock listed next to the names of all underwriters in the preceding table.

The following table shows the per share and total public offering price, underwriting discounts and commissions, and proceeds before expenses to us. These amounts are shown assuming both no exercise and full exercise of the underwriters' option to purchase up to an additional 6,000,000 shares of common stock.


Total
Per Share	No Exercise	Full Exercise
Public offering price	$5.05	$202,000,000	$232,300,000
Underwriting discounts and commissions to be paid by us	$0.214625	$8,585,000	$9,872,750
Proceeds, before expenses, to us	$4.835375	$193,415,000	$222,427,250

The estimated offering expenses payable by us, exclusive of the underwriting discounts and commissions, are approximately $625,000. We have agreed to reimburse the underwriters for expenses relating to clearance of this offering with the Financial Industry Regulatory Authority up to $30,000.

Our common stock is listed on the New York Stock Exchange under the trading symbol "JOBY".

We and all directors and officers have agreed that, without the prior written consent of Morgan Stanley & Co. LLC on behalf of the underwriters, we and they will not, and will not publicly disclose an intention to, during the period ending 90 days after the date of this prospectus supplement (the "Restricted Period"):

Morgan Stanley & Co. LLC, in its sole discretion, may release the common stock and other securities subject to the lock-up agreements described above in whole or in part at any time.

In order to facilitate the offering of our common stock, the underwriters may engage in transactions that stabilize, maintain or otherwise affect the price of the common stock. Specifically, the underwriters may sell more shares than they are obligated to purchase under the underwriting agreement, creating a short position. A short sale is covered if the short position is no greater than the number of shares available for purchase by the underwriters under the option. The underwriters can close out a covered short sale by exercising the option or purchasing shares in the open market. In determining the source of shares to close out a covered short sale, the underwriters will consider, among other things, the open market price of shares compared to the price available under the option. The underwriters may also sell shares in excess of the option, creating a naked short position. The underwriters must close out any naked short position by purchasing shares in the open market. A naked short position is more likely to be created if the underwriters are concerned that there may be downward pressure on the price of the common stock in the open market after pricing that could adversely affect investors who purchase in this offering. As an additional means of facilitating this offering, the underwriters may bid for, and purchase, shares of common stock in the open market to stabilize the price of the common stock. These activities may raise or maintain the market price of the common stock above independent market levels or prevent or retard a decline in the market price of the common stock. The underwriters are not required to engage in these activities and may end any of these activities at any time.

We and the underwriters have agreed to indemnify each other against certain liabilities, including liabilities under the Securities Act.

A prospectus supplement in electronic format may be made available on websites maintained by one or more underwriters, or selling group members, if any, participating in this offering. The representatives may agree to allocate a number of shares of common stock to underwriters for sale to their online brokerage account holders. Internet distributions will be allocated by the representatives to underwriters that may make Internet distributions on the same basis as other allocations.

The underwriters and their respective affiliates are full service financial institutions engaged in various activities, which may include securities trading, commercial and investment banking, financial advisory, investment

management, investment research, principal investment, hedging, financing and brokerage activities. Certain of the underwriters and their respective affiliates have, from time to time, performed, and may in the future perform, various financial advisory and investment banking services for us, for which they received or will receive customary fees and expenses.

In addition, in the ordinary course of their various business activities, the underwriters and their respective affiliates may make or hold a broad array of investments and actively trade debt and equity securities (or related derivative securities) and financial instruments (including bank loans) for their own account and for the accounts of their customers and may at any time hold long and short positions in such securities and instruments. Such investment and securities activities may involve our securities and instruments. The underwriters and their respective affiliates may also make investment recommendations or publish or express independent research views in respect of such securities or instruments and may at any time hold, or recommend to clients that they acquire, long or short positions in such securities and instruments.

ABOUT THIS PROSPECTUS

This prospectus is part of a registration statement that we filed with the U.S. Securities and Exchange Commission (the "SEC"), as a "well-known seasoned issuer" as defined in Rule 405 under the Securities Act of 1933, as amended (the "Securities Act"), using a "shelf" registration process. By using a shelf registration statement, we may sell securities from time to time and in one or more offerings, and the selling securityholders to be named in a supplement to this prospectus may, from time to time, sell shares of common stock from time to time in one or more offerings as described in this prospectus. Each time that we or the selling securityholders offer and sell securities, we or the selling securityholders will provide a prospectus supplement to this prospectus that contains specific information about the securities being offered and sold and the specific terms of that offering. We may also authorize one or more free writing prospectuses to be provided to you that may contain material information relating to these offerings.

All statements contained or incorporated by reference in this prospectus other than statements of historical fact, including statements regarding our future financial position and results of operations, our business strategy and plans and our objectives for future operations, are forward-looking statements.

You should not rely upon forward-looking statements as predictions of future events. We have based the forward-looking statements contained or incorporated by reference in this prospectus primarily on our current expectations and projections about future events and trends that we believe may affect our business, financial condition, results of operations and prospects. The outcome of the events described in these forward-looking statements is subject to risks, uncertainties and other factors including those described in, or incorporated by reference into, the section titled "Risk Factors" and elsewhere in this prospectus. Moreover, we operate in a very competitive and rapidly changing environment. New risks and uncertainties emerge from time to time and it is not possible for us to predict all risks and uncertainties or the extent to which any factor or combination of factors may cause actual results to differ materially from those contained in any forward-looking statements we may make in this prospectus or the documents incorporated by reference herein. We cannot assure you that the results, events and circumstances reflected in the forward-looking statements will be achieved or occur. Actual results, events or circumstances could differ materially and adversely from those described or anticipated in the forward-looking statements.

The forward-looking statements made in, or incorporated by reference into, this prospectus relate only to events as of the date on which the statements are made. We undertake no obligation to update any forward-looking statements made or incorporated by reference in this prospectus to reflect events or circumstances after the date of this prospectus or to reflect new information or the occurrence of unanticipated events, except as required by law. We may not actually achieve the plans, intentions or expectations disclosed in our forward-looking statements and you should not place undue reliance on our forward-looking statements.

RISK FACTORS

Investment in any securities offered pursuant to this prospectus and the applicable prospectus supplement involves risks. Before deciding whether to invest in our securities, you should carefully consider the risk factors incorporated by reference to our most recent Annual Report on Form 10-K and any subsequent Quarterly Reports on Form 10-Q or Current Reports on Form 8-K, and all other information contained or incorporated by reference into this prospectus, as updated by our subsequent filings under the Exchange Act, and the risk factors and other information contained in the applicable prospectus supplement and any applicable free writing prospectus. The occurrence of any of these risks might cause you to lose all or part of your investment in the offered securities. There may be other unknown or unpredictable economic, business, competitive, regulatory or other factors that could have material adverse effects on our future results. Past financial performance may not be a reliable indicator of future performance, and historical trends should not be used to anticipate results or trends in future periods. If any of these risks actually occurs, our business, financial condition, results of operations or cash flow could be seriously harmed. This could cause the trading price of our securities to decline, resulting in a loss of all or part of your investment. Please also carefully read the section titled "Special Note Regarding Forward-Looking Statements" included in our most recent Annual Report on Form 10-K and any subsequent Quarterly Reports on Form 10-Q or Current Reports on Form 8-K.

USE OF PROCEEDS

Table of Contents

DESCRIPTION OF CAPITAL STOCK

The following description of our capital stock is not complete and may not contain all the information you should consider before investing in our capital stock. This description is summarized from, and qualified in its entirety by reference to, our certificate of incorporation, which has been publicly filed with the SEC. See the section titled "Where You Can Find More Information; Incorporation by Reference."

Our authorized capital stock consists of:

•1,400,000,000 shares of common stock, $0.0001 par value; and

•100,000,000 shares of preferred stock, $0.0001 par value.

Common Stock

Our common stock is not entitled to preemptive or other similar subscription rights to purchase any of Joby Aviation's securities. Our common stock is neither convertible nor redeemable. Unless our board of directors determines otherwise, we will issue all of our capital stock in uncertificated form.

Voting Rights

Each holder of our common stock is entitled to one vote per share on each matter submitted to a vote of stockholders, except as provided by our Amended and Restated Certificate of Incorporation (the "Certificate of Incorporation") and outlined below. Our Bylaws provide that the holders of a majority of the capital stock issued and outstanding and entitled to vote thereat, present in person or represented by proxy, will constitute a quorum at all meetings of the stockholders for the transaction of business. When a quorum is present, the affirmative vote of a majority of the votes cast is required to take action, unless otherwise specified by law, our Bylaws or our Certificate of Incorporation, and except for the election of directors, which is determined by a plurality vote. There are no cumulative voting rights. In addition, the affirmative vote of holders of 66 2/3% of the voting power of all of the then outstanding voting stock will be required to take certain actions, including amending certain provisions of our amended and restated certificate of incorporation, such as the provisions relating to amending our amended and restated bylaws, the classified board and director liability.

To comply with restrictions imposed by federal law on foreign ownership of U.S. air transportation operations, our Certificate of Incorporation and our Bylaws restrict voting of shares of our capital stock by non-U.S. citizens. The restrictions imposed by federal law currently require that no more than 25% of our voting stock be voted, directly or indirectly, by persons who are not U.S. citizens, and that our president and at least two-thirds of the members of our board of directors be U.S. citizens. Under our Certificate of Incorporation and Bylaws, we or any designated transfer agent shall maintain a Foreign Stock Record for registered common stock known to us to be owned and/or controlled by non-U.S. citizens. In the event that we determine that the common stock registered on the Foreign Stock Record exceeds the permitted percentage, sufficient shares shall be removed from the Foreign Stock Record in reverse chronological order based upon the date of registration therein so that the number of shares entered does not exceed the permitted percentage; provided, that upon the vesting of any Sponsor Shares pursuant to the Sponsor Agreement, dated February 23, 2021, by and among Joby Aviation, Reinvent Sponsor LLC (the "Sponsor") and Joby Aero, Inc. (the "Sponsor Agreement"), such Sponsor Shares held by the Sponsor shall be deemed registered on the Foreign Stock Record before the registration of any Joby Aviation capital stock held by any other Non-U.S. citizen. If at any time while we are subject to (or control a subsidiary that is subject to) the requirement that an air carrier be a "citizen of the United States" (as defined in Section 40102 of the Act and administrative interpretations issued by the Department of Transportation, its predecessors and successors, from time to time) non-U.S. citizens at any time own and/or control in excess of the permitted percentage, the voting rights of the shares of our common stock in excess and not registered on the Foreign Stock Record will be automatically suspended until the earlier of (i) the transfer of such shares to a person or entity who is not a Non-U.S. citizen or (ii) the registration of such shares on the Foreign Stock Record.

Table of Contents

Other Rights

Each holder of our common stock is subject to, and may be adversely affected by, the rights of the holders of any series of our preferred stock that we may designate and issue in the future.

Liquidation Rights

If we are involved in voluntary or involuntary liquidation, dissolution or winding up of our affairs, or a similar event, each holder of our common stock will participate pro rata in all assets remaining after payment of liabilities, subject to prior distribution rights of our preferred stock, if any, then outstanding.

Transfer Agent

The transfer agent and registrar for our common stock is Continental Stock Transfer & Trust Company.

Dividend

Each holder of shares of our capital stock is entitled to the payment of dividends and other distributions as may be declared by our board of directors from time to time out of our assets or funds legally available for dividends or other distributions. These rights are subject to the preferential rights of the holders of our preferred stock, if any, and any contractual limitations on our ability to declare and pay dividends.

Preferred Stock

Our board of directors has authority to issue shares of our preferred stock in one or more series, to fix for each such series such voting powers, designations, preferences, qualifications, limitations or restrictions thereof, including dividend rights, conversion rights, redemption privileges and liquidation preferences for the issue of such series all to the fullest extent permitted by the Delaware General Corporation Law (the "DGCL"). The issuance of our preferred stock, while providing flexibility in connection with possible acquisitions and other corporate purposes, could, among other things, have the effect of decreasing the trading price of our common stock, restricting dividends on our capital stock, diluting the voting power of our common stock, impairing the liquidation rights of our capital stock, or delaying or preventing a change in control of Joby Aviation.

Section 203 of the Delaware General Corporation Law

Our Certificate of Incorporation contains a provision opting out of Section 203 of the DGCL. However, our Certificate of Incorporation contains provisions that are similar to Section 203 of the DGCL. Specifically, our Certificate of Incorporation provides that, subject to certain exceptions, we are not able to engage in a "business combination" with any "interested stockholder" for three years following the date that the person became an interested stockholder, unless:

•prior to such time, our board of directors approved either the business combination or the transaction that resulted in the stockholder becoming an interested stockholder;

•upon consummation of the transaction that resulted in the stockholder becoming an interested stockholder, the interested stockholder owned at least 85% of our voting stock outstanding at the time the transaction commenced, excluding certain shares; or

•at or subsequent to that time, the business combination is approved by our board of directors and at an annual or special meeting of stockholders, and not by written consent, by the affirmative vote of at least 66 2/3% of our outstanding voting stock that is not owned by the interested stockholder.

Generally, a "business combination" includes a merger, asset or stock sale, consolidation involving us and the "interested stockholder" or other transactions resulting in a financial benefit to the interested stockholder. Subject to certain exceptions, an "interested stockholder" is any entity or person who, together with that entity's or person's affiliates and associates, owns or within the previous three years owned, 15% or more of our outstanding voting stock. For purposes of this section only, "voting stock" has the meaning given to it in Section 203 of the DGCL.

Table of Contents

Under certain circumstances, this provision makes it more difficult for a person who would be an "interested stockholder" to effect various business combinations with us for a period of three years. This provision may encourage companies interested in acquiring us to negotiate in advance with our board of directors. These provisions also may have the effect of preventing changes in our board of directors and may make it more difficult to accomplish transactions that stockholders may otherwise deem to be in their best interests.

Our Certificate of Incorporation provides that certain parties shall not be deemed to be "interested stockholders" for purposes of this provision.

Anti-takeover Effects of the Certificate of Incorporation and the Bylaws

Our Certificate of Incorporation and Bylaws contain provisions that may delay, defer or discourage another party from acquiring control of Joby Aviation. We expect that these provisions, which are summarized below, will discourage coercive takeover practices or inadequate takeover bids. These provisions are also designed to encourage persons seeking to acquire control of Joby Aviation to first negotiate with our board of directors, which we believe may result in an improvement of the terms of any such acquisition in favor of our stockholders. However, these provisions also give our board of directors the power to discourage mergers that some stockholders may favor.

Undesignated Preferred Stock

Our board of directors has the authority, without further action by our stockholders, to issue undesignated preferred stock with voting or other rights or preferences as designated from time to time by our board of directors. The existence of authorized but unissued shares of preferred stock, or the terms of any such preferred stock, could impede the success of any attempt to change control of Joby Aviation. These and other provisions may have the effect of deterring hostile takeovers or delaying changes in control or management of Joby Aviation.

Special Meetings of Stockholders

Our Certificate of Incorporation provides that a special meeting of stockholders may be called by the (a) the Chairperson of our board of directors, (b) our board of directors, (c) our Chief Executive Officer or (d) our President, provided that such special meeting may be postponed, rescheduled or cancelled by our board of directors or other person calling the meeting. These provisions might delay the ability of stockholders to force consideration of a proposal or for stockholders controlling a majority of our capital stock to take any action, including the removal of directors.

Requirements for Advance Notification of Stockholder Nominations and Proposals

Our Bylaws establish advance notice procedures with respect to stockholder proposals and the nomination of candidates for election as directors, other than nominations made by or at the direction of our board of directors or a committee of the board of directors. These provisions might preclude stockholders from bringing matters before our annual meeting of stockholders or from making nominations for directors at our annual meeting of stockholders if the proper procedures are not followed. These provisions may also discourage or deter a potential acquirer from conducting a solicitation of proxies to elect the acquirer's own slate of directors or otherwise attempting to change control of Joby Aviation.

Classified Board of Directors

Our Certificate of Incorporation provides that our board of directors is divided into three classes of directors, with the classes to be as nearly equal in number as possible, and with each director serving a three-year term. As a result, approximately one-third of the board of directors will be elected each year. The classification of directors has the effect of making it more difficult for stockholders to change the composition of our board of directors.

Action by Written Consent

Our Certificate of Incorporation provides that any action required or permitted to be taken by the stockholders must be effected at an annual or special meeting of stockholders, and may not be taken by written consent in lieu of a meeting.

Table of Contents

No Cumulative Voting

The DGCL provides that stockholders are not entitled to cumulate votes in the election of directors unless a corporation's certificate of incorporation provides otherwise. Our Certificate of Incorporation does not provide for cumulative voting.

Amendment of the Certificate of Incorporation and Bylaws

Our board of directors is expressly authorized to adopt, amend or repeal the Bylaws, subject to the power of our stockholders entitled to vote with respect thereto to adopt, amend or repeal the Bylaws. Our stockholders have the power to adopt, amend or repeal the Bylaws; provided, that in addition to any vote of the holders of any class or series of our stock required by applicable law or by our Certificate of Incorporation or Bylaws, the adoption, amendment or repeal of our Bylaws by our stockholders shall require the affirmative vote of the holders of at least two-thirds of the voting power of all of the then outstanding shares of our voting stock entitled to vote generally in an election of directors.

Additionally, the vote of at least 66 2/3% of the total voting power of our outstanding shares entitled to vote thereon, voting together as a single class, is required to amend certain provisions of our Certificate of Incorporation, including those relating to the terms of our authorized preferred stock (Article V(B)), the authority and composition of our board of directors (Article VII), special meetings of our stockholders and the ability of our stockholders to act by written consent (Article VIII), limitation of liability of our directors (Article IX), restrictions similar to Section 203 of the DGCL (Article X), our obligation to indemnify our directors and officers to the fullest extent permitted by law (Article XI), exclusive jurisdiction of certain legal proceedings involving our stockholders (Article XII), and restrictions on ownership or control by non-citizens (Article XIV).

Events of Default

"Event of Default" means with respect to any series of debt securities, any of the following:

•default in the payment of any interest upon any debt security of that series when it becomes due and payable, and continuance of such default for a period of 30 days (unless the entire amount of the payment is deposited by us with the trustee or with a paying agent prior to the expiration of the 30-day period);

•default in the payment of principal of any security of that series at its maturity;

•default in the performance or breach of any other covenant or warranty by us in the indenture (other than a covenant or warranty that has been included in the indenture solely for the benefit of a series of debt securities other than that series), which default continues uncured for a period of 60 days after we receive written notice from the trustee or Joby and the trustee receive written notice from the holders of not less than 25% in principal amount of the outstanding debt securities of that series as provided in the indenture;

•certain voluntary or involuntary events of bankruptcy, insolvency or reorganization of Joby;

•any other Event of Default provided with respect to debt securities of that series that is described in the applicable prospectus supplement. (Section 6.1)

No Event of Default with respect to a particular series of debt securities (except as to certain events of bankruptcy, insolvency or reorganization) necessarily constitutes an Event of Default with respect to any other series of debt securities. (Section 6.1) The occurrence of certain Events of Default or an acceleration under the indenture may constitute an event of default under certain indebtedness of ours or our subsidiaries outstanding from time to time.

We will provide the trustee written notice of any Default or Event of Default within 30 days of becoming aware of the occurrence of such Default or Event of Default, which notice will describe in reasonable detail the status of such Default or Event of Default and what action we are taking or propose to take in respect thereof. (Section 6.1)

If an Event of Default with respect to debt securities of any series at the time outstanding occurs and is continuing, then the trustee or the holders of not less than 25% in principal amount of the outstanding debt securities of that series may, by a notice in writing to us (and to the trustee if given by the holders), declare to be due and payable immediately the principal of (or, if the debt securities of that series are discount securities, that portion of the principal amount as may be specified in the terms of that series) and accrued and unpaid interest, if any, on all debt securities of that series. In the case of an Event of Default resulting from certain events of bankruptcy, insolvency or reorganization, the principal (or such specified amount) of and accrued and unpaid interest, if any, on all outstanding debt securities will become and be immediately due and payable without any declaration or other act on the part of the trustee or any holder of outstanding debt securities. At any time after a declaration of acceleration with respect to debt securities of any series has been made, but before a judgment or decree for payment of the money due has been obtained by the trustee, the holders of a majority in principal amount of the outstanding debt securities of that series may rescind and annul the acceleration if all Events of Default, other than the non-payment of accelerated principal and interest, if any, with respect to debt securities of that series, have been cured or waived as provided in the indenture. (Section 6.2) We refer you to the prospectus supplement relating to any series of debt securities that are discount securities for the particular provisions relating to acceleration of a portion of the principal amount of such discount securities upon the occurrence of an Event of Default.

The indenture provides that the trustee may refuse to perform any duty or exercise any of its rights or powers under the indenture unless the trustee receives indemnity satisfactory to it against any cost, liability or expense that

Table of Contents

might be incurred by it in performing such duty or exercising such right or power. (Section 7.1(e)) Subject to certain rights of the trustee, the holders of a majority in principal amount of the outstanding debt securities of any series will have the right to direct the time, method and place of conducting any proceeding for any remedy available to the trustee or exercising any trust or power conferred on the trustee with respect to the debt securities of that series. (Section 6.12)

No holder of any debt security of any series will have any right to institute any proceeding, judicial or otherwise, with respect to the indenture or for the appointment of a receiver or trustee, or for any remedy under the indenture, unless:

•that holder has previously given to the trustee written notice of a continuing Event of Default with respect to debt securities of that series; and

•the holders of not less than 25% in principal amount of the outstanding debt securities of that series have made written request, and offered indemnity or security satisfactory to the trustee, to the trustee to institute the proceeding as trustee, and the trustee has not received from the holders of not less than a majority in principal amount of the outstanding debt securities of that series a direction inconsistent with that request and has failed to institute the proceeding within 60 days. (Section 6.7)

Notwithstanding any other provision in the indenture, the holder of any debt security will have an absolute and unconditional right to receive payment of the principal of, premium, if any, and any interest on that debt security on or after the due dates expressed in that debt security and to institute suit for the enforcement of payment. (Section 6.8)

The indenture requires us, within 120 days after the end of our fiscal year, to furnish to the trustee a statement as to compliance with the indenture. (Section 4.3) If a Default or Event of Default occurs and is continuing with respect to the securities of any series and if it is known to a responsible officer of the trustee, the trustee shall mail to each holder of the securities of that series notice of a Default or Event of Default within 90 days after it occurs or, if later, after a responsible officer of the trustee has knowledge of such Default or Event of Default. The indenture provides that the trustee may withhold notice to the holders of debt securities of any series of any Default or Event of Default (except in payment on any debt securities of that series) with respect to debt securities of that series if the trustee determines in good faith that withholding notice is in the interest of the holders of those debt securities. (Section 7.5)

Modification and Waiver

We and the trustee may modify, amend or supplement the indenture or the debt securities of any series without the consent of any holder of any debt security:

•to cure any ambiguity, defect or inconsistency;

•to comply with covenants in the indenture described above under the heading "Consolidation, Merger and Sale of Assets";

•to provide for uncertificated securities in addition to or in place of certificated securities;

•to add guarantees with respect to debt securities of any series or secure debt securities of any series;

•to surrender any of our rights or powers under the indenture;

•to add covenants or events of default for the benefit of the holders of debt securities of any series;

•to comply with the applicable procedures of the applicable depositary;

•to make any change that does not adversely affect the rights of any holder of debt securities;

•to provide for the issuance of, and establish the form and terms and conditions of, debt securities of any series as permitted by the indenture;

Table of Contents

•to effect the appointment of a successor trustee with respect to the debt securities of any series and to add to or change any of the provisions of the indenture to provide for or facilitate administration by more than one trustee; or

•to comply with requirements of the SEC in order to effect or maintain the qualification of the indenture under the Trust Indenture Act. (Section 9.1)

We may also modify and amend the indenture with the consent of the holders of at least a majority in principal amount of the outstanding debt securities of each series affected by the modifications or amendments. We may not make any modification or amendment without the consent of the holders of each affected debt security then outstanding if that amendment will:

•reduce the amount of debt securities whose holders must consent to an amendment, supplement or waiver;

•reduce the rate of or extend the time for payment of interest (including default interest) on any debt security;

•reduce the principal of or premium on or change the fixed maturity of any debt security or reduce the amount of, or postpone the date fixed for, the payment of any sinking fund or analogous obligation with respect to any series of debt securities;

•reduce the principal amount of discount securities payable upon acceleration of maturity;

•waive a default in the payment of the principal of, premium, if any, or interest on any debt security (except a rescission of acceleration of the debt securities of any series by the holders of at least a majority in aggregate principal amount of the then outstanding debt securities of that series and a waiver of the payment default that resulted from such acceleration);

•make the principal of or premium or interest on any debt security payable in currency other than that stated in the debt security;

•make any change to certain provisions of the indenture relating to, among other things, the right of holders of debt securities to receive payment of the principal of, premium, if any, and interest on those debt securities and to institute suit for the enforcement of any such payment and to waivers or amendments; or

•waive a redemption payment with respect to any debt security. (Section 9.3)

Except for certain specified provisions, the holders of at least a majority in principal amount of the outstanding debt securities of any series may on behalf of the holders of all debt securities of that series waive our compliance with provisions of the indenture. (Section 9.2) The holders of a majority in principal amount of the outstanding debt securities of any series may on behalf of the holders of all the debt securities of such series waive any past default under the indenture with respect to that series and its consequences, except a default in the payment of the principal of, premium, if any, or any interest on any debt security of that series; provided, however, that the holders of a majority in principal amount of the outstanding debt securities of any series may rescind an acceleration and its consequences, including any related payment default that resulted from the acceleration. (Section 6.13)

Defeasance of Debt Securities and Certain Covenants in Certain Circumstances

Legal Defeasance. The indenture provides that, unless otherwise provided by the terms of the applicable series of debt securities, we may be discharged from any and all obligations in respect of the debt securities of any series (subject to certain exceptions). We will be so discharged upon the irrevocable deposit with the trustee, in trust, of money and/or U.S. government obligations or, in the case of debt securities denominated in a single currency other than U.S. dollars, government obligations of the government that issued or caused to be issued such currency, that, through the payment of interest and principal in accordance with their terms, will provide money or U.S. government obligations in an amount sufficient in the opinion of a nationally recognized firm of independent public

Table of Contents

accountants or investment bank to pay and discharge each installment of principal, premium, if any, and interest on and any mandatory sinking fund payments in respect of the debt securities of that series on the stated maturity of those payments in accordance with the terms of the indenture and those debt securities.

This discharge may occur only if, among other things, we have delivered to the trustee an opinion of counsel stating that we have received from, or there has been published by, the U.S. Internal Revenue Service a ruling or, since the date of execution of the indenture, there has been a change in the applicable U.S. federal income tax law, in either case to the effect that, and based thereon such opinion shall confirm that, the holders of the debt securities of that series will not recognize income, gain or loss for U.S. federal income tax purposes as a result of the deposit, defeasance and discharge and will be subject to U.S. federal income tax on the same amounts and in the same manner and at the same times as would have been the case if the deposit, defeasance and discharge had not occurred. (Section 8.3)

Defeasance of Certain Covenants. The indenture provides that, unless otherwise provided by the terms of the applicable series of debt securities, upon compliance with certain conditions:

•we may omit to comply with the covenant described under the heading "Consolidation, Merger and Sale of Assets" and certain other covenants set forth in the indenture, as well as any additional covenants that may be set forth in the applicable prospectus supplement; and

•any omission to comply with those covenants will not constitute a Default or an Event of Default with respect to the debt securities of that series ("covenant defeasance").

The conditions include:

•depositing with the trustee money and/or U.S. government obligations or, in the case of debt securities denominated in a single currency other than U.S. dollars, government obligations of the government that issued or caused to be issued such currency, that, through the payment of interest and principal in accordance with their terms, will provide money in an amount sufficient in the opinion of a nationally recognized firm of independent public accountants or investment bank to pay and discharge each installment of principal of, premium, if any, and interest on and any mandatory sinking fund payments in respect of the debt securities of that series on the stated maturity of those payments in accordance with the terms of the indenture and those debt securities; and

•delivering to the trustee an opinion of counsel to the effect that the holders of the debt securities of that series will not recognize income, gain or loss for U.S. federal income tax purposes as a result of the deposit and related covenant defeasance and will be subject to U.S. federal income tax on the same amounts and in the same manner and at the same times as would have been the case if the deposit and related covenant defeasance had not occurred. (Section 8.4)

No Personal Liability of Directors, Officers, Employees or Securityholders

None of our past, present or future directors, officers, employees or securityholders, as such, will have any liability for any of our obligations under the debt securities or the indenture or for any claim based on, or in respect or by reason of, such obligations or their creation. By accepting a debt security, each holder waives and releases all such liability. This waiver and release is part of the consideration for the issue of the debt securities. However, this waiver and release may not be effective to waive liabilities under U.S. federal securities laws, and it is the view of the SEC that such a waiver is against public policy.

Governing Law

The indenture and the debt securities, including any claim or controversy arising out of or relating to the indenture or the securities, will be governed by the laws of the State of New York.

The indenture will provide that we, the trustee and the holders of the debt securities (by their acceptance of the debt securities) irrevocably waive, to the fullest extent permitted by applicable law, any and all right to trial by

Table of Contents

jury in any legal proceeding arising out of or relating to the indenture, the debt securities or the transactions contemplated thereby.

The indenture will provide that any legal suit, action or proceeding arising out of or based upon the indenture or the transactions contemplated thereby may be instituted in the federal courts of the United States of America or the courts of the State of New York, in each case located in the City of New York, and we, the trustee and the holder of the debt securities (by their acceptance of the debt securities) irrevocably submit to the non-exclusive jurisdiction of such courts in any such suit, action or proceeding. The indenture will further provide that service of any process, summons, notice or document by mail (to the extent allowed under any applicable statute or rule of court) to such party's address set forth in the indenture will be effective service of process for any suit, action or other proceeding brought in any such court. The indenture will further provide that we, the trustee and the holders of the debt securities (by their acceptance of the debt securities) irrevocably and unconditionally waive any objection to the laying of venue of any suit, action or other proceeding in the courts specified above and irrevocably and unconditionally waive and agree not to plead or claim any such suit, action or other proceeding has been brought in an inconvenient forum. (Section 10.10)

GLOBAL SECURITIES

Book-Entry, Delivery and Form

Unless we indicate differently in any applicable prospectus supplement or free writing prospectus, the securities initially will be issued in book-entry form and represented by one or more global notes or global securities (collectively, "global securities"). The global securities will be deposited with, or on behalf of, DTC, as depositary, and registered in the name of Cede & Co., the nominee of DTC. Unless and until it is exchanged for individual certificates evidencing securities under the limited circumstances described below, a global security may not be transferred except as a whole by the depositary to its nominee or by the nominee to the depositary, or by the depositary or its nominee to a successor depositary or to a nominee of the successor depositary.

DTC has advised us that it is:

•a limited-purpose trust company organized under the New York Banking Law;

•a "banking organization" within the meaning of the New York Banking Law;

•a member of the Federal Reserve System;

•a "clearing corporation" within the meaning of the New York Uniform Commercial Code; and

•a "clearing agency" registered pursuant to the provisions of Section 17A of the Exchange Act.

DTC holds securities that its participants deposit with DTC. DTC also facilitates the settlement among its participants of securities transactions, such as transfers and pledges, in deposited securities through electronic computerized book-entry changes in participants' accounts, thereby eliminating the need for physical movement of securities certificates. "Direct participants" in DTC include securities brokers and dealers, including underwriters, banks, trust companies, clearing corporations and other organizations. DTC is a wholly owned subsidiary of The Depository Trust & Clearing Corporation ("DTCC"). DTCC is the holding company for DTC, National Securities Clearing Corporation and Fixed Income Clearing Corporation, all of which are registered clearing agencies. DTCC is owned by the users of its regulated subsidiaries. Access to the DTC system is also available to others, which we sometimes refer to as indirect participants, that clear through or maintain a custodial relationship with a direct participant, either directly or indirectly. The rules applicable to DTC and its participants are on file with the SEC.

Purchases of securities under the DTC system must be made by or through direct participants, which will receive a credit for the securities on DTC's records. The ownership interest of the actual purchaser of a security, which we sometimes refer to as a beneficial owner, is in turn recorded on the direct and indirect participants' records. Beneficial owners of securities will not receive written confirmation from DTC of their purchases. However, beneficial owners are expected to receive written confirmations providing details of their transactions, as well as periodic statements of their holdings, from the direct or indirect participants through which they purchased securities. Transfers of ownership interests in global securities are to be accomplished by entries made on the books of participants acting on behalf of beneficial owners. Beneficial owners will not receive certificates representing their ownership interests in the global securities, except under the limited circumstances described below.

To facilitate subsequent transfers, all global securities deposited by direct participants with DTC will be registered in the name of DTC's partnership nominee, Cede & Co., or such other name as may be requested by an authorized representative of DTC. The deposit of securities with DTC and their registration in the name of Cede & Co. or such other nominee will not change the beneficial ownership of the securities. DTC has no knowledge of the actual beneficial owners of the securities. DTC's records reflect only the identity of the direct participants to whose accounts the securities are credited, which may or may not be the beneficial owners. The participants are responsible for keeping account of their holdings on behalf of their customers.

So long as the securities are in book-entry form, you will receive payments and may transfer securities only through the facilities of the depositary and its direct and indirect participants. We will maintain an office or agency in the location specified in the prospectus supplement for the applicable securities, where notices and demands in

Table of Contents

respect of the securities and the indenture may be delivered to us and where certificated securities may be surrendered for payment, registration of transfer or exchange.

Conveyance of notices and other communications by DTC to direct participants, by direct participants to indirect participants and by direct participants and indirect participants to beneficial owners will be governed by arrangements among them, subject to any legal requirements in effect from time to time.

Redemption notices will be sent to DTC. If less than all of the securities of a particular series are being redeemed, DTC's practice is to determine by lot the amount of the interest of each direct participant in the securities of such series to be redeemed.

Neither DTC nor Cede & Co. (or such other DTC nominee) will consent or vote with respect to the securities. Under its usual procedures, DTC will mail an omnibus proxy to us as soon as possible after the record date. The omnibus proxy assigns the consenting or voting rights of Cede & Co. to those direct participants to whose accounts the securities of such series are credited on the record date, identified in a listing attached to the omnibus proxy.

So long as securities are in book-entry form, we will make payments on those securities to the depositary or its nominee, as the registered owner of such securities, by wire transfer of immediately available funds. If securities are issued in definitive certificated form under the limited circumstances described below and unless if otherwise provided in the description of the applicable securities herein or in the applicable prospectus supplement, we will have the option of making payments by check mailed to the addresses of the persons entitled to payment or by wire transfer to bank accounts in the United States designated in writing to the applicable trustee or other designated party at least 15 days before the applicable payment date by the persons entitled to payment, unless a shorter period is satisfactory to the applicable trustee or other designated party.

Redemption proceeds, distributions and dividend payments on the securities will be made to Cede & Co., or such other nominee as may be requested by an authorized representative of DTC. DTC's practice is to credit direct participants' accounts upon DTC's receipt of funds and corresponding detail information from us on the payment date in accordance with their respective holdings shown on DTC records. Payments by participants to beneficial owners will be governed by standing instructions and customary practices, as is the case with securities held for the account of customers in bearer form or registered in "street name." Those payments will be the responsibility of participants and not of DTC or us, subject to any statutory or regulatory requirements in effect from time to time. Payment of redemption proceeds, distributions and dividend payments to Cede & Co., or such other nominee as may be requested by an authorized representative of DTC, is our responsibility, disbursement of payments to direct participants is the responsibility of DTC, and disbursement of payments to the beneficial owners is the responsibility of direct and indirect participants.

Except under the limited circumstances described below, purchasers of securities will not be entitled to have securities registered in their names and will not receive physical delivery of securities. Accordingly, each beneficial owner must rely on the procedures of DTC and its participants to exercise any rights under the securities and the indenture.

The laws of some jurisdictions may require that some purchasers of securities take physical delivery of securities in definitive form. Those laws may impair the ability to transfer or pledge beneficial interests in securities.

DTC may discontinue providing its services as securities depositary with respect to the securities at any time by giving reasonable notice to us. Under such circumstances, in the event that a successor depositary is not obtained, securities certificates are required to be printed and delivered.

As noted above, beneficial owners of a particular series of securities generally will not receive certificates representing their ownership interests in those securities. However, if:

•DTC notifies us that it is unwilling or unable to continue as a depositary for the global security or securities representing such series of securities or if DTC ceases to be a clearing agency registered under the Exchange Act at a time when it is required to be registered and a successor depositary is not

Table of Contents

appointed within 90 days of the notification to us or of our becoming aware of DTC's ceasing to be so registered, as the case may be;

•we determine, in our sole discretion, not to have such securities represented by one or more global securities; or

•an Event of Default has occurred and is continuing with respect to such series of securities,

we will prepare and deliver certificates for such securities in exchange for beneficial interests in the global securities. Any beneficial interest in a global security that is exchangeable under the circumstances described in the preceding sentence will be exchangeable for securities in definitive certificated form registered in the names that the depositary directs. It is expected that these directions will be based upon directions received by the depositary from its participants with respect to ownership of beneficial interests in the global securities.

Euroclear and Clearstream

If so provided in the applicable prospectus supplement, you may hold interests in a global security through Clearstream Banking S.A. ("Clearstream") or Euroclear Bank S.A./N.V., as operator of the Euroclear System ("Euroclear") either directly if you are a participant in Clearstream or Euroclear or indirectly through organizations which are participants in Clearstream or Euroclear. Clearstream and Euroclear will hold interests on behalf of their respective participants through customers' securities accounts in the names of Clearstream and Euroclear, respectively, on the books of their respective U.S. depositaries, which in turn will hold such interests in customers' securities accounts in such depositaries' names on DTC's books.

Clearstream and Euroclear are securities clearance systems in Europe. Clearstream and Euroclear hold securities for their respective participating organizations and facilitate the clearance and settlement of securities transactions between those participants through electronic book-entry changes in their accounts, thereby eliminating the need for physical movement of certificates.

Payments, deliveries, transfers, exchanges, notices and other matters relating to beneficial interests in global securities owned through Euroclear or Clearstream must comply with the rules and procedures of those systems. Transactions between participants in Euroclear or Clearstream, on one hand, and other participants in DTC, on the other hand, are also subject to DTC's rules and procedures.

Investors will be able to make and receive through Euroclear and Clearstream payments, deliveries, transfers and other transactions involving any beneficial interests in global securities held through those systems only on days when those systems are open for business. Those systems may not be open for business on days when banks, brokers and other institutions are open for business in the United States.

Cross-market transfers between participants in DTC, on the one hand, and participants in Euroclear or Clearstream, on the other hand, will be effected through DTC in accordance with the DTC's rules on behalf of Euroclear or Clearstream, as the case may be, by their respective U.S. depositaries; however, such cross-market transactions will require delivery of instructions to Euroclear or Clearstream, as the case may be, by the counterparty in such system in accordance with the rules and procedures and within the established deadlines (European time) of such system. Euroclear or Clearstream, as the case may be, will, if the transaction meets its settlement requirements, deliver instructions to its U.S. depositary to take action to effect final settlement on its behalf by delivering or receiving interests in the global securities through DTC, and making or receiving payment in accordance with normal procedures for same-day fund settlement. Participants in Euroclear or Clearstream may not deliver instructions directly to their respective U.S. depositaries.

Due to time zone differences, the securities accounts of a participant in Euroclear or Clearstream purchasing an interest in a global security from a direct participant in DTC will be credited, and any such crediting will be reported to the relevant participant in Euroclear or Clearstream, during the securities settlement processing day (which must be a business day for Euroclear or Clearstream) immediately following the settlement date of DTC. Cash received in Euroclear or Clearstream as a result of sales of interests in a global security by or through a participant in Euroclear or Clearstream to a direct participant in DTC will be received with value on the settlement date of DTC but will be

Table of Contents

available in the relevant Euroclear or Clearstream cash account only as of the business day for Euroclear or Clearstream following DTC's settlement date.
