Pew III and the Company (the “Letter Agreement”) and (iii) the Voting and Support Agreement, dated as of August 3, 2025, by and among HNI, Mr. Pew and Susan H. Taylor (the “Voting Agreement”), Mr. Pew converted 2,216,114 shares of Class B common stock, no par value, of the Company (the “Company Class B Common Stock”) into 2,216,114 shares of Class A common stock, no par value, of the Company (the “Company Class A Common Stock”) pursuant to the voluntary conversion procedure under the Company’s Second Restated Articles of Incorporation, dated as of July 13, 2011, as amended (the “Articles”), resulting in an Event of Automatic Conversion (as defined in the Articles) and the automatic conversion of all shares of Company Class B Common Stock into shares of Company Class A Common Stock on a one-for-one basis (the “Conversion”). After the Conversion, shares of Company Class B Common Stock that were converted into shares of Company Class A Common Stock will be retired and canceled. As of August 8, 2025, following the Conversion, there were 114,717,466 shares of Company Class A Common Stock outstanding and no shares of Company Class B Common Stock outstanding.

Pursuant to the Articles, (a) the certificates that represented shares of Company Class B Common Stock immediately prior to the Conversion shall, upon the Conversion, represent the same number of shares of Company Class A Common Stock; (b) a person entitled to receive shares of Company Class A Common Stock issuable upon the Conversion will be treated for all purposes as the record holder of such shares of Company Class A Common Stock at and as of the time of the Conversion; and (c) the rights of such person as a holder of shares of Company Class B Common Stock that have been converted in the Conversion shall cease and terminate at and as of the time of the Conversion.

The Articles provide that holders of converted Company Class B Common Stock shall deliver their certificates, duly endorsed in blank or accompanied by proper instruments of transfer, to the principal office of the Company or the office of any transfer agent for shares of the Company Class A Common Stock, together with a notice setting out the name or names (with addresses) and denominations in which the certificate or certificates representing such shares of Company Class A Common Stock are to be issued and including instructions for delivery thereof. Pursuant to the Articles, upon such delivery in connection with the Conversion, the Company or its transfer agent will promptly issue and deliver at the stated address to the holder of shares of Company Class A Common Stock a certificate or certificates representing the number of shares of Company Class A Common Stock to which the holder is entitled by reason of the Conversion, and will cause such shares of Company Class A Common Stock to be registered in the name of such holder.
