        <footnote id="F1">The Reporting Persons previously disclosed an in-kind pro rata distribution for no consideration of shares of common stock of Itron, Inc. (the &quot;Issuer&quot;) by an investment fund for which Scopia Capital Management LP serves as investment manager to investors in such investment fund that took place on March 11, 2019. The previously filed Form 4 stated that none of the Reporting Persons nor any Investment Vehicle (as defined in the previously filed Form 4) retained a pecuniary interest in such shares of common stock of the Issuer.  The Form 4 is amended to delete that statement as 1,202 shares of common stock were transferred to Matthew Sirovich and 653 shares of common stock were transferred to Jeremy Mindich in the in-kind pro rata distribution for no consideration that was exempt from Section 16 as a change in form of beneficial ownership pursuant to Rule 16a-13.</footnote>
