CARG 0001718636 Trevisan Jason 2 CANAL PARK 4TH FLOOR CAMBRIDGE MA 02141 1 1 Chief Executive Officer Class A Common Stock 2022-02-08 4 F 0 13849 34.88 D 588399 D Class A Common Stock 80000 I See Footnote Shares withheld for payment of tax liability upon vesting of restricted stock units ("RSUs"). The Reporting Person previously reported a prior award of performance-based RSUs in Table II of the Form 4 filed by the Reporting Person on February 12, 2021 (the "Prior Form 4"). These awards were amended by the Compensation Committee of the Issuer's Board of Directors on February 8, 2022 to revise the vesting terms thereunder from performance-based to time-based and therefore are being moved to Table I, consistent with prior grants of time-based RSUs by the Issuer to the Reporting Person. The total reported in Column 5 of this Form 4 includes the 126,368 time-based RSUs previously reported as performance-based RSUs in Table II of the Prior Form 4. Each such RSU represents a contingent right to receive one share of the Issuer's Class A Common Stock. Subject to the Reporting Person's continuous service as an employee of the Issuer, 6.25% of the RSUs vested on each of April 1, 2021, July 1, 2021, October 1, 2021 and January 1, 2022, and 6.25% of the RSUs will vest on the last day of each three-month period thereafter until January 1, 2025. Such vesting may be accelerated in connection with a Change of Control (as defined in the Issuer's Omnibus Incentive Compensation Plan). These shares are held directly by the Trevisan 2021 Grantor Retained Annuity Trust dated March 12, 2021 (the "GRAT"), of which the Reporting Person is trustee. The Reporting Person's children are the beneficiaries of the GRAT. /s/ Josh Goldstein, as attorney-in-fact 2022-02-10
