Explanation of Responses:

( 1 )Includes 734.0792 shares acquired under the Kimball International Dividend Reinvestment Plan. ( 2 )On June 1, 2023, pursuant to the Agreement and Plan of Merger, dated as of March 7, 2023 (the "Merger Agreement"), by and among Kimball International, Inc. ("Kimball"), HNI Corporation ("HNI") and Ozark Merger Sub, Inc. ("Merger Sub"), Merger Sub merged with and into Kimball (the "Merger"), with Kimball surviving the Merger as a wholly-owned subsidiary of HNI. ( 3 )Pursuant to the Merger Agreement, each share of Kimball common stock issued and outstanding immediately prior to the effective time of the Merger was converted into the right to receive (A) $9.00 in cash, without interest (the "Cash Consideration"), and (B) 0.1301 (the "Exchange Ratio") of a share of HNI common stock, par value $1.00. On May 31, 2023 (the last full trading day prior to the Merger), the closing price of one share of HNI common stock was $25.50. ( 4 )At the effective time of the Merger, each outstanding Kimball restricted stock unit award that is not subject to performance vesting conditions was assumed by HNI and thereafter constitutes a restricted stock unit award with respect to a number of shares of HNI common stock, determined by multiplying (i) each share of Kimball common stock subject to such Kimball restricted stock unit award by (ii) the sum of (A) the Exchange Ratio and (B) the quotient of the sum of the Cash Consideration plus the dividend equivalents accrued thereon, divided by $26.59, the volume weighted average price per share of HNI common stock on the New York Stock Exchange for the ten consecutive trading days ending the two trading days prior to the closing of the Merger as reported by Bloomberg, L.P. (such price, the ?Parent Share Price?).
