Item 2.03. Creation of a Direct Financial\nObligation or an Obligation under an Off-Balance-Sheet Arrangement of a\nRegistrant.

On October 15, 2026, Tucson Electric Power\nCompany (TEP) entered into a second amended and\nrestated credit agreement\nwith MUFG Bank, Ltd. (MUFG), as administrative agent, and a group of lenders (2026 Credit\nAgreement). The 2026 Credit Agreement amends and restates in its entirety the credit facility entered into on October 15, 2021, which included a $250 million revolving credit and letter of credit\nfacility, with a $15 million swingline sublimit and a $50 million letter of\ncredit sublimit. The 2026 Credit Agreement provides\nfor a $350 million revolving credit, with a $15\nmillion swingline sublimit and\na $50 million letter of credit sublimit. The 2026 Credit Agreement\nalso permits TEP to request increases in the aggregate commitments, in an\namount not to exceed $50 million, on no more than two occasions, subject to\ncertain conditions. It expires on October 15, 2031, at which time all\noutstanding amounts thereunder will be due and payable. The final maturity date\nis subject to two one-year extensions if certain conditions are satisfied.

TEP expects that borrowings will be made from\ntime to time under the revolving credit facility for working capital and other\ngeneral corporate purposes and that letters of credit will be issued from time\nto time to support energy procurement and hedging activities and for other lawful purposes.

Interest rates and fees under the 2026 Credit\nAgreement are based on a pricing grid tied to TEP’s credit ratings. Borrowings\nunder the revolving credit facility bear interest at a variable interest rate\nconsisting of a spread over SOFR or Alternate Base Rate. Alternate Base Rate is\nequal to the greater of (i) MUFG’s prime rate, (ii) the\nfederal funds rate plus ½ of 1%, or (iii) Term SOFR for an interest\nperiod of one month plus 1%, but in no event less than zero percent. The\ninterest rate presently in effect on borrowings is Term SOFR plus 1.00% for SOFR\nloans or Alternate Base Rate plus 0.00% for Alternate Base Rate loans.

The 2026 Credit Agreement is\nunsecured and ranks pari passu with TEP’s other senior unsecured debt\nobligations.

The 2026 Credit Agreement contains a\nnumber of covenants which restrict TEP and its subsidiaries, including\nrestrictions on liens, mergers and sales of assets. The 2026 Credit\nAgreement also requires TEP not to exceed a maximum leverage ratio of 0.65 to 1.00\nat the end of any fiscal quarter. Under the terms of the 2026 Credit\nAgreement, TEP has agreed not to pay dividends to its parent, UNS Energy Corporation\n(other than in additional shares of its common stock), unless it maintains\ncompliance with the 2026 Credit Agreement.

Upon the occurrence and continuance of an event\nof default under the 2026 Credit Agreement,\noutstanding borrowings may become immediately due and payable. Events of\ndefault include the failure to make payments required thereunder or to comply\nwith the covenants contained therein, change in control, as defined, or certain\nbankruptcy events with respect to TEP or certain subsidiaries. In addition, an\nevent of default would include the failure of TEP or certain subsidiaries to\nmake required payments on indebtedness in excess of $40 million or events\ngiving the holders of such indebtedness the right to require repayment of such\nindebtedness.

The foregoing description of the 2026 Credit\nAgreement does not purport to be complete and is qualified in\nits entirety by reference to the complete text of the 2026 Credit Agreement, a\ncopy of which is filed as Exhibit 4.1 to this Current Report\non Form 8-K and is incorporated by reference herein.
