Exhibit 99.1

CORRECTION -- Rover Group, Inc. Announces “Redemption Fair Market Value” in Connection With Redemption of its Outstanding Warrants

SEATTLE, Jan. 5, 2022 (GLOBE NEWSWIRE) -- In a release issued under the same headline on December 29, 2021 by Rover Group, Inc. (NASDAQ: ROVR), please note that in the bulleted section in the fifth paragraph, the Redemption Fair Market Value of $10.12 should have been $10.14; and the 0.2544 shares of Class A Common Stock holders would receive should have been 0.2558 shares. The corrected release follows:

Rover Group, Inc. (“Rover”) (NASDAQ: ROVR), the world’s largest online marketplace for pet care, today announced the “Redemption Fair Market Value” in connection with its previously announced redemption of its outstanding Warrants (as defined below). The Redemption Fair Market Value will be used to determine the number of shares of Class A common stock, par value $0.0001 per share (the “Class A Common Stock”), that will be issued on a “cashless” exercise of a Warrant subject to the terms of the Warrant Agreement (as defined below).

On December 13, 2021, Rover (f/k/a Nebula Caravel Acquisition Corp. (“Caravel”)) announced that it will redeem all of its outstanding warrants (the “Public Warrants”) to purchase shares of Class A Common Stock that were issued as part of the units sold in Caravel’s initial public offering (the “IPO”) under the Warrant Agreement dated December 8, 2020, between Rover and American Stock Transfer & Trust Company, LLC, as warrant agent (the “Warrant Agent”) (as amended by the First Amendment to Warrant Agreement, dated December 10, 2021, the “Warrant Agreement”). In addition, Rover announced that it will redeem all of its outstanding warrants to purchase Class A Common Stock that were issued under the Warrant Agreement in a private placement simultaneously with the IPO (together with the Public Warrants, the “Warrants”) on the same terms as the outstanding Public Warrants.

The redemption will occur at 5:00 p.m. New York City time on January 12, 2022 (the “Redemption Date”), before which time the Warrants may be exercised on a “cashless” basis. Warrant holders may no longer exercise Warrants and receive Class A Common Stock in exchange for payment in cash of the $11.50 per Warrant exercise price. All Warrants that remain unexercised following 5:00 p.m. New York City time on the Redemption Datewill be void and no longer exercisable, and the holders of those Warrants will be entitled to receive only the redemption price of $0.10 per Warrant (or as otherwise described in the Redemption Notice for holders who hold their Public Warrants in “street name”).

In connection with the redemption, the Warrant Agent previously mailed a redemption notice (the “Redemption Notice”) on Rover’s behalf, and Rover committed to provide registered holders of the outstanding Warrants the calculation of the Redemption Fair Market Value (as defined in the Warrant Agreement to mean the volume weighted average price of the Class A Common Stock during the 10 trading days immediately following the date on which the Redemption Notice was sent to the registered holders of the Warrants).

The Warrant Agent has mailed a notice (the “Redemption Fair Market Value Notice”) on Rover’s behalf to each of the registered holders of the outstanding Warrants informing holders:

•that the Redemption Fair Market Value is $10.14; and

•as a result, holders who elect to exercise their Warrants on a “cashless basis” will be entitled to receive 0.2558 shares of Class A Common Stock per Warrant.

For additional information, including information on how holders may exercise their Warrants, see the Redemption Notice. For copies of the Redemption Notice and the Redemption Fair Market Value Notice, an update on the estimated number of shares of Class A Common Stock outstanding post-redemption, and answers to frequently asked questions, please visit Rover’s investor relations website https://investors.rover.com.

None of Rover, its board of directors or employees has made or is making any representation or recommendation to any holder of the Warrants as to whether to exercise or refrain from exercising any Warrants.

The shares of Class A Common Stock issuable upon exercise of the Warrants have been registered by Rover under the Securities Act of 1933, as amended, and are covered by a registration statement filed on Form S-1 with, and declared effective by, the Securities and Exchange Commission (Registration No. 333-259519).

Exhibit 99.2

BY FIRST CLASS MAIL

December 29, 2021 (as amended on January 5, 2022 to correct the Redemption Fair Market Value and the number of shares to be received upon a “cashless exercise” of Warrants)

NOTICE OF “REDEMPTION FAIR MARKET VALUE”TO THE HOLDERS OF ROVER GROUP, INC. PUBLIC WARRANTS (CUSIP 77936F111) AND PRIVATE WARRANTS

Reference is made to that certain Redemption Notice (as defined below) under which Rover Group, Inc. (the “Company”) committed to provide registered holders of the Company’s Warrants (as defined below) notice of the following information on this date. 

Background

On December 13, 2021, the Company (f/k/a Nebula Caravel Acquisition Corp. (“Caravel”)) mailed a notice of redemption (the “Redemption Notice”) indicating that the Company is redeeming, at 5:00 p.m. New York City time on January 12, 2022 (the “Redemption Date”), all of the Company’s outstanding warrants (the “Public Warrants”) to purchase shares of the Company’s Class A common stock, par value $0.0001 per share (the “Class ACommon Stock”), that were issued under the Warrant Agreement, dated December 8, 2020, between the Company and American Stock Transfer & Trust Company, LLC, as warrant agent (as amended by the First Amendment to Warrant Agreement dated December 10, 2021, the “Warrant Agreement”), as part of the units sold in Caravel’s initial public offering (the “IPO”) for a redemption price of $0.10 per Public Warrant (the “Redemption Price”). In addition, the Company will redeem all of its outstanding warrants to purchase shares of Class A Common Stock that were issued under the Warrant Agreement in a private placement simultaneously with the IPO (the “Private Warrants” and, together with the Public Warrants, the “Warrants”) on the same terms as the outstanding Public Warrants.

At the close of trading on the Redemption Date, the Public Warrants will cease trading on Nasdaq.

Redemption Fair Market Value

The “Redemption Fair Market Value” is determined in accordance with Section 6.5 of the Warrant Agreement based on the volume weighted average price of the Class A Common Stock during the 10 trading days immediately following the date on which the Redemption Notice was sent to the registered holders of the Warrants.

Based on the date the Redemption Notice was mailed, the Redemption Fair Market Value is $10.14 (corrected from $10.12 in the prior notice). 

Cashless Exercise of Warrants

The Warrants may be exercised on a cashless basis by the holders thereof until 5:00 p.m. New York City time on the Redemption Date to acquire fully paid and non-assessable shares of Class A Common Stock underlying such Warrants. Payment upon exercise of the Warrants may be made on a “cashless basis” in which the exercising holder will receive a number of shares of Class A Common Stock determined in accordance with the terms of Section 6.5 of the Warrant Agreement and based on the Redemption Date and the Redemption Fair Market Value. Those who hold their Warrants in “street name” should immediately contact their broker to determine their broker’s procedure for exercising their Warrants.

In particular, should a holder elect to exercise Warrants on a “cashless basis,” such holder would receive a number of shares of Class A Common Stock determined by reference to the table set forth in Section 6.5 of the Warrant Agreement.Based on the Redemption Fair Market Value and the number of months between the Redemption Date and the expiration of the Warrants, the number of shares of Class A Common Stock to be issued for each Warrant that is exercised on a “cashless basis” is 0.2558 shares (corrected from 0.2544 shares in the prior notice).

If any holder of Warrants would, after taking into account all of such holder’s Warrants exercised at one time, be entitled to receive a fractional interest in a share of Class A Common Stock, the number of shares the holder will be entitled to receive will be rounded down to the nearest whole number of shares.

Warrant holders may no longer exercise Warrants and receive Class A Common Stock in exchange for payment in cash of the $11.50 per Warrant exercise price.

Redemption of Warrants

Any Warrants that remain unexercised at 5:00 p.m. New York City time on the Redemption Date will be void and no longer exercisable, and the holders of those Warrants will be entitled to receive only the Redemption Price of $0.10 per Warrant.

Additional Information and Questions Regarding Redemption and Exercise

For additional information, including information on how holders may exercise their Warrants and procedures for those who hold Warrants in “street name,” see the Redemption Notice. For a copy of the Redemption Notice, please visit the Company’s investor relations website at https://investors.rover.com. In addition, a copy of the Redemption Notice was attached as Exhibit 99.2 to the Current Report on Form 8-K filed by the Company on December 13, 2021, and is available on the website of the U.S. Securities and Exchange Commission at www.sec.gov.
