In addition, pursuant to Rule 416(a) under the Securities Act of 1933, this Registration Statement also covers such indeterminate number of additional shares as may be authorized in the event of an adjustment as a result of an increase in the number of issued shares of Common Stock resulting from the payment of stock dividends or stock splits or certain other capital adjustments. For the purpose of computing the registration fee only, the price shown is based upon the price of $16.53 per share, the average of the high and low prices for the Common Stock of the Registrant as reported in the Nasdaq Global Select Market on October 13, 2025, in accordance with Rule 457(c) and (h). Pursuant to General Instruction E to Form S-8, a filing fee is only being paid with respect to the registration of additional securities for the Plan.</ffd:OfferingNote>
