SIERRA BANCORP

Interest-earning cash balances were discussed above in the “Investments” section, but the Company also maintains a certain level of cash on hand in the normal course of business, as well as non-earning deposits at other financial institutions. The Company’s balance of cash and due from banks depends on the timing of collection of outstanding cash items (checks), the amount of cash held in the branches, and the reserve requirement among other things, and it is subject to significant fluctuations in the normal course of business. While cash flows are normally predictable within limits, those limits are fairly broad and the Company manages its short-term cash position through the utilization of overnight loans to, and borrowings from, correspondent banks, including the FRB and the FHLB. Should a large “short” overnight position persist for any length of time, the Company typically raises money through focused retail deposit gathering efforts or by adding brokered time deposits. If a “long” position is prevalent, the Company could let brokered deposits or other wholesale borrowings roll off as they mature, or invest excess liquidity into investments or loans, subject to the Company’s risk tolerances. The Company’s balance of non-earning cash and due from banks was $81.8 million at September 30, 2025, relative to $79.6 million at December 31, 2024.

Foreclosed assets are discussed above in the section titled “Nonperforming Assets.”

Net premises and equipment decreased by $0.4 million during the first nine months of 2025, to $15.1 million. This decline was mostly a result of depreciation in the first nine months of 2025.

Goodwill was $27.4 million at September 30, 2025, unchanged during the first nine months of 2025. Goodwill is tested for impairment annually, unless events and circumstances exist which indicate that an impairment test should be performed. The annual goodwill impairment test was last performed on October 1, 2025, and it was determined that no impairment existed. Management continues to evaluate whether or not a triggering event occurs, or circumstances change

that would more likely than not reduce the fair value of the Company below its carrying amount before the next annual test in 2025.

Bank-owned life insurance, with a balance of $68.7 million at September 30, 2025, increased $15.6 million during the first nine months of 2025, primarily due to the purchase of additional life insurance policies. Additional details are discussed above in the “Noninterest Income and Noninterest Expense” section.

The remainder of other assets consists primarily of right-of-use assets tied to operating leases, accrued interest receivable, deferred taxes, investments in bank stocks, prepaid assets, investments in low-income housing credits, investments in SBA loan funds, and other miscellaneous assets. Bank stocks include Pacific Coast Bankers Bank (PCBB) stock (marked to market value annually) and restricted stock related to the Federal Home Loan Bank of San Francisco (FHLB SF) stock held in conjunction with our FHLB borrowings. Both the PCBB and FHLB SF stock are not deemed to be marketable or liquid. Our net deferred tax asset is evaluated as of every reporting date pursuant to FASB guidance, and we have determined that no impairment exists.
