 has taken an uncertain position that more likely than not would not be sustained upon examination by the IRS. The plan administrator has analyzed the tax positions taken by the Plan, and has concluded that as of December 31, 2024, and 2023, there were no uncertain positions taken or expected to be taken that would require recognition of a liability (or asset) or disclosure in the financial statements. The Plan is subject to routine audits by taxing jurisdictions; however, there are currently no audits for any tax periods in progress.

#### 7. Risks and Uncertainties
The Plan provides for various investment options. Investments are exposed to various risks, such as interest rate, market, and credit risks. Due to the level of risk associated with certain investments, it is at least reasonably possible that changes in the values of investments will occur in the near term and that such changes could materially affect participants’ account balances and the amounts reported in the Statements of Net Assets Available for Benefits.

#### 8. Subsequent Events
The plan administrator has evaluated subsequent events from the date of these financial statements and supplemental schedule, through the date of issuance of this report, and determined that, other than the Ametros Plan Merger and plan amendments discussed above in Note 1: Description of the Plan, no significant events were identified requiring recognition or disclosure.
