Item 4.

Purpose of Transaction.

Item 4 of the Statement is amended by adding the following at the end thereof:

On November 24, 2020, the Dolby Family Fund gifted an aggregate of 97,000 shares of Class A Common Stock to an unaffiliated third-party charity (such share gift, the “November 2020 DDF Gift”). On various dates from December 9, 2020 to April 19, 2021, the Dagmar Dolby Fund gifted an aggregate of 354,300 shares of Class A Common Stock to unaffiliated third-party charities (the “2020-21 DDF Gifts”). On March 18, 2021 and June 1, 2021, the Dagmar Dolby Trust gifted an aggregate of 39,500 shares of Class A Common Stock to unaffiliated third-party charities (the “2021 DDT Gifts”).

On November 29, 2021, 1,427,000 shares of Class B Common Stock that were previously held indirectly by the Dagmar Dolby 2020 Trust BB-2 were transferred to the Dagmar Dolby Trust in exchange for property of equivalent value (the “November 2021 GRAT Share Exchange”). The shares subject to the November 2021 GRAT Share Exchange were valued at $85.635 per share, the mean of the high and low trading price for the Class A Common Stock on November 29, 2021, for such purpose. The November 2021 GRAT Share Exchange was accomplished in accordance with the terms of the Dagmar Dolby 2020 Trust BB-2, pursuant to which Dagmar Dolby, as the Settlor of the GRAT, retained the right to substitute property of equivalent value, valued on the date of substitution, in the GRAT.

Also on November 29, 2021, the Dagmar Dolby 2020 Trust BB-2 transferred 1,573,000 shares of Class B Common Stock to the Dagmar Dolby Trust (the “November 2021 GRAT Annuity Share Distribution”). The Dagmar Dolby 2020 Trust BB-2’s trust instrument requires an annual annuity payment to the Dagmar Dolby Trust, and the November 2021 GRAT Annuity Share Distribution was effected in satisfaction of the annuity payment requirements, and in accordance with the terms, of such trust instrument. The November 2021 GRAT Annuity Share Distribution was a transfer for no value, without the payment or receipt of any funds or other consideration by any Reporting Person in exchange therefor.
