Dear Stockholder,

As a stockholder of Joby Aero, Inc. (“Joby”), please find attached a Notice of Stockholder Action Taken Without a Meeting and Notice of Statutory Appraisal Rights Pursuant to Sections 228 and 262 of the General Corporation Law of the State of Delaware, which provides you notice with respect to certain actions including (1) the Joby requisite holders’ approval and adoption of that certain Agreement and Plan of Merger, dated as of February 23, 2021 (as it may be amended and/or restated from time to time, the “Merger Agreement”), by and among Joby, Reinvent Technology Partners, a Cayman Islands exempted company limited by shares (which shall migrate to and domesticate as a Delaware corporation prior to the Closing (as defined therein)) (“RTP”), and RTP Merger Sub Inc., a Delaware corporation and a direct wholly owned subsidiary of RTP (“Merger Sub”) and (2) the Joby requisite holders’ consent to and affirmation of the transactions contemplated by the Merger Agreement being treated as a “Liquidation Event” pursuant to Joby’s certificate of incorporation and a “Sale of the Company” pursuant to the Voting Agreement (as defined in the attached).

Under the Merger Agreement, Merger Sub will merge with and into Joby, with Joby surviving the merger as a wholly owned subsidiary of RTP (the “Merger”; such subsidiary, the “surviving corporation”). Additionally, RTP will change its name to Joby Aviation, Inc.

FAQS

Will my Joby shares automatically be exchanged for Joby Aviation shares?

Yes, shares of Joby will be exchanged automatically for shares of Joby PubCo pursuant to the terms of the Merger Agreement. Joby PubCo’s exchange agent will provide additional communications regarding your holdings following the closing. The exchange ratio will be based on a $5 billion valuation and will be calculated in accordance with the terms of the Merger Agreement.

Will Joby stockholders be subject to a lock up?

Yes, all Joby stockholders are subject to a 180-day lockup from the date of the closing of this transaction. However, certain tenured Joby employees may have up to 20% of their shares released from the lock up at closing; provided, that the total amount of such shares released will not exceed 5,000,000 shares. A lockup period is a window of time when stockholders are not allowed to sell shares. If you are a tenured Joby employee who is eligible for a partial release from the 180-day lockup, Joby PubCo or its exchange agent will reach out to you following the closing of the transaction.

Certain significant stockholders of Joby and its directors and officers have agreed to either (1) a one-year lockup subject to certain early priced based releases or (2) a staggered lockup for up to five years subject to certain early priced releases. These stockholders have agreed to enter into a separate lock up agreement at closing.

When will I get information about trading my shares?

Following the end of your lock-up period, your shares of Joby PubCo will become tradeable subject to compliance with securities laws. You can obtain further information at that time from the exchange agent engaged by Joby PubCo.

If I was an employee or former employee, will signing this consent impact any options or restricted stock units I hold?

No, your options or restricted stock units, if any, will be exchanged for options or restricted stock units exercisable for shares of Joby PubCo using the exchange ratio as set forth in the Merger Agreement.
