As of December 28, 2025, there were no diversified issuances in the Company’s securities portfolio in an unrealized loss position.

The Company does not believe there has been any significant decline in the creditworthiness of the issuers and the Company does not have current liquidity needs that would necessitate a sale of any material investments prior to maturity. Therefore, the Company has not recorded an allowance for credit losses on the investment securities as of December 28, 2025.

The fair value and location of all investment securities are included in “Fair Value Measurements” in Note 5 below.
