Explanation of Responses:

Remarks:

Effective June 29, 2018, W. Thorpe McKenzie (the "Reporting Person"), a Director of XBiotech, Inc. (the "Company"), adopted a stock trading plan (the "10b5-1 Plan"). For personal tax and financial planning purposes, Mr. McKenzie presently intends to sell up to approximately 15% of his total holdings in the Company in monthly installments, beginning on July 30, 2018 and which will terminate on or before February 28, 2019. The 10b5-1 Plan was adopted in accordance with guidelines specified by Rule 10b5-1 under the Securities Exchange Act of 1934, as amended, and the Company's insider trading policies. Rule 10b5-1 permits corporate officers, directors and others to adopt written, pre-arranged stock trading plans when they are not in possession of material, non-public information. Using these plans, insiders may gradually diversify their investment portfolios and spread stock trades over a period of time regardless of any material, non-public information they may receive after adopting their plans. In accordance with Rule 10b5-1, Mr. McKenzie will have no discretion over the sales of his shares of common stock under the plan. As reflected in this Form 4, W. Thorpe McKenzie (the "Reporting Person") sold 385,000 shares of XBiotech Inc. common stock in a private transaction on October 4, 2018. The Reporting Person has terminated the 10B5-1 Plan that was put into effect on June 29, 2018.
