(NASDAQ:XBIT) ("Xbiotech") announced today that it commenced a "modified Dutch auction" issuer tender offer to purchase up to $80,000,000 in value of its common shares, or such lesser number of common shares as are properly tendered and not properly withdrawn, at a price not greater than $4.00 nor less than $3.80 per common share, to the seller in cash, less any applicable withholding taxes and without interest (the "Offer"). The Offer is made upon the terms and subject to the conditions described in an offer to purchase dated May 17, 2023, the related letter of transmittal and the website established for purposes of effectuating the Offer.
