Item 3 — Legal Proceedings
Xcel Energy is involved in various litigation matters that are being defended and handled in the ordinary course of business. The
assessment of whether a loss is probable or is a reasonable possibility, and whether the loss or a range of loss is estimable, often
involves a series of complex judgments about future events. Management maintains accruals for such losses that are probable of
being incurred and subject to reasonable estimation. Management is sometimes unable to estimate an amount or range of a reasonably
possible loss in certain situations, including but not limited to when (1) the damages sought are indeterminate, (2) the proceedings are
in the early stages, or (3) the matters involve novel or unsettled legal theories. In such cases, there is considerable uncertainty
regarding the timing or ultimate resolution of such matters, including a possible eventual loss.

Item 7 and Note 12 to the consolidated financial statements for a discussion of proceedings involving utility rates and other regulatory
matters.
Item 4 — Mine Safety Disclosures
