On April 13, 2026, Itron, Inc. (the "Company" or "Itron") was notified that an unauthorized third party had gained access to certain of its systems.

The Company activated its cybersecurity response plan and launched an investigation with the support of external advisors to assess, mitigate, remediate, and contain the unauthorized activity. The Company's response efforts included proactively notifying law enforcement.

The Company took action to remediate and remove the unauthorized activity and has not observed any subsequent unauthorized activity within its corporate systems. Further, no unauthorized activity was observed in the customer hosted portion of its systems.

As a result of the Company's contingency plans and data backup systems, the Company's operations have continued in all material respects. In addition, Itron currently expects that a significant portion of its direct costs incurred relating to the incident will be reimbursed by its insurers.

The Company is evaluating what legal filings and regulatory notifications might be required because of this incident and intends to take appropriate action based on its review and findings.

While the Company's investigation and assessment of this incident is ongoing, the Company does not currently believe the incident has had or is reasonably likely to have a material impact on the Company.
