The following description of the ServisFirst Bank 401(k) Profit Sharing Plan and Trust (the “Plan”) provides only general information. Participants should refer to the plan document for a complete description of the Plan’s provisions.

General

The Plan is a defined contribution plan covering all employees of ServisFirst Bank (the “Company”) who have attained age 21 except union employees whose employment is governed under a collective bargaining agreement and certain nonresident aliens who have no earned income from sources within the United States. The Plan is subject to the provisions of the Employee Retirement Income Security Act of 1974 (“ERISA”).

Contributions

Participants contribute a percentage of pretax and Roth after-tax annual compensation (as defined by the Plan), not to exceed federal limits. Participants who have attained age 50 before the end of the Plan year are eligible to make catch-up contributions. Participants may also contribute amounts representing distributions from other qualified defined benefit or defined contribution plans. The Company contributes a safe harbor matching contribution equal to 100 percent of participant salary deferrals that do not exceed 4% of compensation. The Company may also contribute discretionary matching or profit- sharing contributions as determined by the Company’s Board of Directors. No such discretionary contributions were made during 2025 or 2024.

Investment Options

Participants direct the investment of their accounts into various investment options offered by the Plan. The Plan currently offers investments in various mutual funds, a money market fund, a stable value investment contract and the common stock of ServisFirst Bancshares, Inc., the Company’s parent company.

Participant Accounts

Each participant’s account is credited with the participant’s contribution, the Company’s contribution, plan earnings or losses from that account’s investment activities, and is charged with benefit payments and allocations of administrative expenses. Allocations are based on participant earnings or account balance, as defined. The benefit to which a participant is entitled is the benefit that can be provided from the participant’s vested account.

Administration

The Plan is administered by the Senior Vice President of Human Resources of the Company (the “plan administrator”). The plan administrator is responsible for general administration of the Plan and interpretation and execution of the Plan’s provisions. Charles Schwab Trust Bank serves as the custodian of the Plan’s assets and as the plan trustee. Envestnet Retirement Services serves as an investment advisor. Schwab Retirement Plan Services, Inc. serves as the recordkeeper and third-party administrator (“TPA”) for the Plan.

Payment of Benefits

On termination of service due to separation, death, disability, or retirement, a participant may elect to receive a lump-sum amount equal to the value of the participant’s vested interest in his or her account. A participant may also elect installment payments over a fixed reasonable period of time for required minimum distributions only. A participant may obtain an in-service or hardship withdrawal from his or her tax-deferred contributions subject to certain conditions and penalties (as defined by the Plan).

Vesting

Participants are immediately vested in their voluntary and safe harbor matching contributions plus actual earnings thereon. Vesting in the Company’s discretionary contribution portion of their accounts plus earnings thereon is based on years of continuous service. A participant is 100 percent vested in discretionary contributions after five years of credited service.

Forfeited Accounts

Forfeitures of terminated, nonvested participant accounts may first be used to pay plan expenses and then may be used to reduce current or future Company discretionary contributions or reallocated to participant accounts as an additional Company contribution. At December 31, 2025 and 2024, forfeited non-vested accounts totaled $1,474 and $4,592, respectively. All forfeitures were used to reduce the Company’s matching contributions in 2025 and 2024.

Notes Receivable from Participants

The Plan does not permit loans to participants.

Plan Termination

Although the Company has not expressed any intent to do so, it has the right under the Plan to discontinue its contributions at any time and to terminate the Plan subject to the provisions of ERISA. In the event of plan termination, participants would become 100 percent vested in their Company contributions.

Administrative Expenses

Certain administrative expenses, including accounting fees, have been paid by the Company. Contract administrative fees are paid by the Participants.

The framework for measuring fair value provides a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical financial instruments (level 1) and the lowest priority to unobservable inputs (level 3).

Measurement of fair value under U.S. GAAP establishes a hierarchy that prioritizes observable and unobservable inputs used to measure fair value, as of the measurement date, into three broad levels, which are described below:

The financial instrument’s fair value measurement level within the fair value hierarchy is based on the lowest level of any input that is significant to the fair value measurement. Valuation techniques used need to maximize the use of observable inputs and minimize the use of unobservable inputs.

The following tables present the Plan’s investments at fair value as of December 31, 2025 and 2024:

The Plan recognizes transfers between the levels as of the actual date of the event or change in circumstances that caused the transfer. There were no gross transfers between the levels at December 31, 2025 and 2024.

The following is a description of the valuation methodologies used for assets measured at fair value. There have been no changes in the methodologies used at December 31, 2025 and 2024.



Mutual funds

Mutual funds are valued at the daily closing price as reported by the fund. Mutual funds held by the Plan are open-end mutual funds that are registered with the Securities and Exchange Commission. These funds are required to publish their daily net asset value (NAV) and to transact at that price and are deemed to be actively traded.

Money market funds

Money market funds are a public investment vehicle valued using $1 as the net asset value (NAV) and are deemed to be actively traded.

ServisFirst Bancshares, Inc. common stock fund

The ServisFirst Bancshares, Inc. common stock fund is a unitized stock fund valued at the net asset value (NAV) and includes shares of common stock valued at quoted market prices, and a nominal amount of cash and cash equivalents to provide liquidity for participant directed transactions.

The Lincoln Stable Value Fixed Account (Fixed Account) is a fully benefit-responsive investment contract issued by the Lincoln National Life Insurance Company with the backing of their general account. As it is not a portfolio of contracts whose yields are based on changes in fair value of underlying assets, this type of investment is considered fairly valued at contract value. The methodology for calculating the interest crediting rate is defined in the contract. Under the terms of the existing contract, the composite crediting rate is currently reset on a quarterly basis and will never be less than the guaranteed minimum interest rate, as defined in the contract. The Plan’s ability to receive amounts due in accordance with fully benefit-responsive investment contracts is dependent on the third-party issuer’s ability to meet its financial obligations. The issuer’s ability to meet its contractual obligations may be affected by future economic and regulatory developments. By definition, the Fixed Account is an investment contract. As a result, the Plan may transact according to the terms defined in the contract at any time. Certain events might limit the availability of the Plan to transact at contract value with the contract issuer. Examples of such events include the Plan’s failure to qualify under Section 401(a) of the Internal Revenue Code or the failure of the trust to be tax-exempt under Section 501(a) of the Internal Revenue Code (“IRC”); premature termination of the contract; Plan termination or merger; changes to the Plan’s prohibition on competing investment options; or bankruptcy of the Plan sponsor or other Plan sponsor events (for example divestitures or spinoffs of a subsidiary) that significantly affect the Plan’s normal operations. No events are probable of occurring that might limit the ability of the Plan to transact at contract value with the participants. In addition, certain events allow the issuer to terminate the contracts with the Plan and settle at an amount different from contract value. Examples of such events include an uncured violation of the Plan’s investment guidelines; a breach of material obligation under the contract; a material misrepresentation; or a material amendment to the agreements without the consent of the issuer.

The Company adopted a prototype non-standardized profit-sharing plan with a cash or deferral arrangement, which received a favorable opinion letter from the Internal Revenue Service, stating that the prototype is designed in accordance with applicable sections of the IRC. The Plan has not obtained or requested a determination letter. However, the plan administrator believes that the Plan is currently designed and being operated in compliance with the applicable requirements of the Internal Revenue Code and that the Plan was qualified and the related trust was tax exempt as of the financial statement date. The Plan’s income tax returns for the past three years are subject to examination by tax authorities and may change upon examination.

U.S. GAAP requires plan management to evaluate tax positions taken by the Plan and recognize a tax liability (or asset) if the Plan has taken an uncertain position that more likely than not would not be sustained upon examination by the Internal Revenue Service. The plan administrator has confirmed that there are no uncertain positions taken that would require recognition of a liability (or asset) or disclosure in the financial statements.

The Plan invests in various investment securities. Investment securities are exposed to various risks such as interest rate, market and credit risks. Because of the level of risk associated with certain investment securities, it is reasonably possible that changes in the values of investment securities could 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.

The Plan paid $74,335 and $57,070 of recordkeeping and investment fees to Charles Schwab during the years ended December 31, 2025 and 2024, respectively. Additionally, Charles Schwab managed Plan investment in its money market fund. Charles Schwab is the trustee and TPA as defined by the Plan and, therefore, these transactions qualify as party-in-interest transactions. Additional expenses paid to parties-in-interest for investment management services aggregated to $98,128 during the year ended December 31, 2025. The Plan paid $145,880 of recordkeeping, administrative and investment management fees to other parties-in-interest during the year ended December 31, 2024.

The Plan also invests in shares of the Company’s parent company. The Company is the Plan sponsor; therefore, these transactions qualify as exempt party‑in‑interest transactions. The Company directly pays any other fees related to the Plan’s operations and provides certain administrative services at no cost to the Plan.
