Structure and Voting Arrangements Behind the First Trust Filing

According to the filing, The Charger Corporation serves as the general partner of both First Trust Portfolios L.P. and First Trust Advisors L.P. First Trust Portfolios L.P. acts as sponsor of certain unit investment trusts that hold shares of Dolby Laboratories, and the filing states that no individual unit investment trust sponsored by First Trust Portfolios L.P. holds more than 3% of any registered investment company issuer's shares. The 17,727 shares attributed solely to shared dispositive power under First Trust Portfolios L.P. represent holdings within those unit investment trusts.

The filing explains that none of the three reporting persons holds the power to vote the shares held by the unit investment trusts. Instead, the filing states that those shares "are voted by the trustee of such unit investment trusts so as to insure that the shares are ordinarily voted as closely as possible in the same manner and in the same general proportion as are the shares held by owners other than such unit investment trusts." First Trust Advisors L.P. is described as acting as portfolio supervisor of the unit investment trusts and as investment advisor or sub-advisor for other registered investment companies, pooled investment vehicles, and separately managed accounts that may also hold Dolby Laboratories shares.

The filing was signed by James M. Dykas, identified as Chief Financial Officer of First Trust Portfolios L.P. and First Trust Advisors L.P., and as Chief Financial Officer and Treasurer of The Charger Corporation, on October 27, 2026. The filers certified that the securities "were acquired and are held in the ordinary course of business and were not acquired and are not held for the purpose of or with the effect of changing or influencing the control of the issuer."
