Filed by Reinvent Technology Partners Y

Pursuant to Rule 425 under the Securities Act of 1933

and deemed filed pursuant to Rule 14a-12

of the Securities Exchange Act of 1934

Subject Company: Aurora Innovation, Inc.

Commission File No. 333-257912

Dear Aurora Stockholders,

As you may know, Aurora Innovation, Inc. (Aurora) is planning to become a public company through a merger with Reinvent Technology Partners Y (RTPY) that is expected to close on November 3 (the Closing). We’d like to provide you with some important information on what to expect as it relates to Aurora securities over the next few weeks.

Equity Management Platform

On the anticipated closing date (November 3), your securities in Carta will be cancelled and exchanged at the applicable exchange ratio for securities in RTPY (to be renamed Aurora Innovation, Inc. under the trading symbol AUR). Because of the administrative processes involved in implementing the share exchange and onboarding with new public company equity management systems, it may be several weeks after Closing before you are able to access your post-closing holdings online. We appreciate your patience!

Upcoming communications: You will receive a welcome letter from Continental during the weeks following closing. This letter will come to you by physical mail. Please keep an eye out for this letter, because it includes important instructions on how to login to the Continental platform and view your holdings online.

After the release of the lock-up restrictions, as well as any vesting or escrow restrictions, you will be able to transfer your shares from Continental to your own brokerage account.

Exchange Ratio

The final exchange ratio that will apply to your Aurora securities is expected to be publicly announced via 8-K after the Closing.

Lock-Up Restrictions

Under Section 6.8 of the bylaws that will be effective upon the Closing (subject to limited exceptions), shares and equity awards held by Aurora shareholders immediately prior to Closing will be subject to lock-up for 180 days following the Closing. During the lock-up period, such shares and equity awards (including any shares underlying such equity awards) may not be sold, transferred, assigned, pledged, or encumbered. In addition, certain significant stockholders, certain directors, and Aurora’s founders will be subject to a four-year lock-up period, with 25% of their shares generally being released annually following the Closing. Assuming the Closing occurs on November 3, 2021, the lock-up is expected to expire on May 2, 2022.

Best regards,

Jessica
