("HomeTrust" and such shares "HomeTrust common stock") being registered is based on an estimate of (i) the maximum number of shares of common stock, no par value, of Blue Ridge Bankshares, Inc. ("Blue Ridge" and such shares, "Blue Ridge common stock") currently outstanding or issuable prior to the merger of Blue Ridge and Kinloch Merger Sub, Inc., a direct, wholly owned subsidiary of HomeTrust (the "merger"), collectively equal to 109,500,000, multiplied by (ii) the exchange ratio of 0.086 of a share of HomeTrust common stock for each share of Blue Ridge common stock.

Estimated solely for the purpose of calculating the registration fee required by Section 6(b) of the Securities Act of 1933, as amended, and calculated in accordance with Rules 457(c) and Rule 457(f)(1) promulgated thereunder, the maximum aggregate offering price ($420,206,250) is (x) the average of the high and the low sale prices of Blue Ridge common stock as reported on NYSE American on October 1, 2026 ($3.8375 per share), multiplied by (y) the estimated maximum number of shares of Blue Ridge common stock that may be exchanged in the merger for the securities being registered (103,100,000).</ffd:OfferingNote>
