Annual Report of Employee Stock Purchase/Savings Plan (Form 11-K)

Note 1 - Plan Description

The GEO Save 401(k) Plan (the "Plan") is a defined contribution plan sponsored by GEO Group, Inc. (the "Company"). The Plan is subject to the provisions of the Employee Retirement Income Security Act of 1974, as amended ("ERISA").

The following is a summary of major plan provisions. Participants should refer to the Plan document for more complete information.

Participation

An employee age 18 or older and not considered to be a highly compensated employee (as defined in the Plan) is eligible to participate in the Plan on the first day of the payroll period following the date of employment. Highly compensated employees are excluded from participation in the Plan.

Contributions and Allocations

The Plan permits tax-deferred contributions from 1% to 75% of a participant's eligible compensation, subject to certain Internal Revenue Code ("IRC") limitations. The Plan also allows participants to make after-tax Roth 401(k) contributions. Participants are vested immediately in their contributions plus actual earnings thereon. The Plan allows for rollovers of vested balances from previous employers' qualified plans. Participants who have attained age 50 before the end of the Plan year are eligible to make catch-up contributions. Participants direct the investment of their contributions into various investment options offered by the Plan.

The Company may contribute to the Plan either annual or bi-weekly matching contributions on behalf of participants who made elective deferrals during such period in an amount determined annually by the Company's management. The Company may, at its discretion, designate a different matching contribution formula for participants at each separate work site, and/or participants with different job classifications. In order to be entitled to an allocation of the Company's discretionary annual matching contribution, participants, as defined under the Plan, must be employed on the last day of the Plan year. Also, the Company, at its discretion, may make a non-elective contribution to the Plan each year. There were no such discretionary non-elective contributions made during the year ended December 31, 2025.

Participant Accounts

Each participant's account is adjusted with the participant's contributions and the participant's withdrawals, and allocations of the Company's contributions, Plan earnings, losses and expenses. Allocations are based on participant earnings and losses or account balances, or specific participant transactions, as defined, as of the date of the allocation. The benefit to which a participant is entitled is the benefit that can be provided from the participant's vested account.

Notes Receivable from Participants

Participants may borrow from their accounts a minimum of $1,000 and a maximum not to exceed the lesser of $50,000, or 50% of their vested account balance. Loans are repayable through payroll deductions over a period not to exceed five years, unless used to acquire a principal residence, in which case the repayment period may not exceed ten years. Loans are secured by balances in participants' vested accounts, and a participant may only have one outstanding loan at a time. The interest rates on loans outstanding are based on the prime rate plus 1%. Generally, principal and interest is paid ratably through monthly payroll deductions.

Vesting

Participants fully vest in the Company's contributions upon completion of three years of vesting service, as defined in the Plan. Additionally, Company contributions become fully vested upon normal retirement age, as defined by the Plan, death, or termination of employment as a result of a total or permanent disability. See vesting schedule below:

Forfeited Accounts

At December 31, 2025 and 2024, forfeited non-vested amounts totaled approximately $776,000 and $949,000, respectively. Any non-vested portion of matching contributions credited to the accounts of participants who withdraw prior to becoming fully vested is forfeited and used by the Company to reduce future matching contributions and/or payment of eligible administrative expenses. The Company utilized approximately $841,000 of forfeitures for the payment of employer matching contributions and administrative expenses during the year ended December 31, 2025.

Payment of Benefits

Eligible participants may elect to receive benefits in a lump-sum payment, a series of payments within one calendar year, a series of annual installments of approximately equal amounts to be paid over a period of five to ten years, or the employee's vested benefit may be used to purchase an immediate or deferred annuity. The amount of benefits paid will be determined by the vested balance in the participant's Plan account at the date of retirement, termination, death or disability.

Voting Rights

Each participant who has an interest in The GEO Group, Inc. Common Stock is entitled to exercise voting rights attributable to the shares allocated to his or her Stock Fund account and is notified by the Trustee, as defined by the Plan, prior to the time that such rights are to be exercised. If the Trustee does not receive timely instructions, the Trustee itself or by proxy shall vote all such shares in the same ratio as the shares with respect to which instructions were received from participants.

Note 2 - Summary of Significant Accounting Policies

Note 3 - Fair Value of Investments

Accounting standards provide a framework for measuring investments at fair value. The framework 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 assets or liabilities (level 1 measurements) and the lowest priority to unobservable inputs (level 3 measurements).

Three levels of inputs may be used to measure fair value:

Level 1 - Inputs to the valuation methodology are unadjusted quoted prices for identical assets or liabilities in active markets that the Plan has the ability to access;

Level 2 - Inputs to the valuation methodology include (i) quoted prices for similar assets or liabilities in active markets, (ii) quoted prices for identical or similar assets or liabilities in inactive markets, (iii) inputs other than quoted prices that are observable for the asset or liability, or (iv) inputs that are derived from or corroborated by observable market data by correlation or other means. If the asset or liability has a specified (contractual) term, the level 2 input must be observable for substantially the full term of the asset or liability; and

Level 3 - Inputs to the valuation methodology are unobservable and significant to the fair value measurement.

A financial instrument's level within the fair value hierarchy is based on the lowest level of any input that is significant to the fair value measurement. The following is a description of the valuation methodologies used for instruments measured at fair value, including the general classification of such instruments pursuant to the valuation hierarchy.

Mutual Funds - These investments are public investment vehicles valued using the Net Asset Value ("NAV") provided by the administrator of the fund. Mutual funds held by the Plan are open-end mutual funds that are registered with the Securities and Exchange Commission. The NAV is a quoted price in an active market and classified within level 1 of the valuation hierarchy. The mutual funds held by the Plan are deemed to be actively traded.

The GEO Group, Inc. Common Stock Fund - The GEO Group, Inc. common stock fund is based on the ending quoted closing price of the common stock of the Company that is held by the account on the last day of the Plan year plus any cash held in the account, and is classified within level 1 of the valuation hierarchy.

Collective Trust Fund - This investment consists of pools of investments used by institutional investors to obtain exposure to equity and fixed income markets. The collective trust fund held by the Plan seeks long-term growth of capital from a high conviction concentrated portfolio of large U.S. stocks. Shares held in the collective trust fund are reported at the NAV as determined by the issuer based on the underlying fair value of its net assets.

The methods described above may produce a fair value calculation that may not be indicative of net realizable value or reflective of future fair values. Furthermore, while the Plan believes its valuation methods are appropriate and consistent with other market participants, the use of different methodologies or assumptions to determine fair value of certain financial instruments could result in a

different fair value measurement at the reporting date. There have been no changes in the methodologies used at December 31, 2025 and 2024.

Note 4 - Separate Account Guaranteed Interest Contract

The Plan has entered into a traditional fully benefit-responsive investment contract with Mass Mutual Retirement Services. The Separate Account Guaranteed Interest Contract ("SAGIC") maintains the contributions in a general account. The account is credited with earnings on the underlying investments and charged for participant withdrawals and administrative expenses. The contract is included in the financial statements at contract value as reported to the Plan by the SAGIC. Contract value represents contributions made under the contract, plus earnings, less participant withdrawals and administrative expenses. Participants may ordinarily direct the withdrawal or transfer of all or a portion of their investment at contract value. The guaranteed investment contract issuer is contractually obligated to repay the principal and a specified interest rate that is guaranteed to the Plan.

As described in Note 2, because the SAGIC is fully benefit-responsive, contract value is the relevant measurement attribute for that portion of the net assets available for benefits attributable to the guaranteed investment contract. There are no reserves against contract value for credit risk of the contract issuer or otherwise. The crediting interest rate is reviewed on a quarterly basis for resetting. The SAGIC does not allow the crediting interest rate below zero percent.

Certain events limit the ability of the Plan to transact at contract value with the issuer. Such events include the following: (1) amendments to the Plan documents (including complete or partial Plan termination or merger with another plan), (2) changes to the Plan's prohibition on competing investment options or deletion of equity wash provisions, (3) bankruptcy of the Plan sponsor or other Plan sponsor events (for example, divestitures or spin-offs of a subsidiary) that cause a significant withdrawal from the Plan, or (4) the failure of the trust to qualify for exemption from federal income taxes or any required prohibited transaction exemption under ERISA. The Plan administrator does not believe that any events which would limit the Plan's ability to transact at contract value with participants are probable of occurring.

The SAGIC does not permit the insurance company to terminate the agreement unless the Plan is not in compliance with the investment agreement.

Note 5 - Plan Termination

Although it has not expressed any intent to do so, the Company 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% vested in their accounts.

Note 6 - Income Tax Status

The Internal Revenue Service issued an opinion letter dated November 14, 2022, indicating that the volume submitter plan document adopted by the Plan, as then designed, was in accordance with applicable sections of the IRC. Although the Plan has been amended since receiving the opinion letter, the Plan administrator believes that the Plan is designed and is currently being operated in compliance with the applicable requirements of the IRC. Therefore, no provision for income taxes has been included in the Plan's financial statements.

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 is subject to routine audits by tax jurisdictions; however, there are currently no audits for any tax periods in progress.

Note 7 - Administrative Expenses

Certain expenses of maintaining the Plan are paid by the Plan, unless otherwise paid by the Company. Expenses that are paid by the Company are excluded from these financial statements. Fees related to the administration of notes receivable from participants are charged directly to the participant's account and are included in administrative expenses. Investment related expenses are included in net appreciation of fair value of investments.

Note 8 - Related Party and Party-In-Interest Transactions

Certain Plan investments held during 2025 and 2024 were issued by MML Investors Services Inc., a subsidiary of Empower Retirement, the Plan's third-party administrator. The Plan also invests in The GEO Group, Inc. common stock and therefore, these transactions qualify as related party and party-in-interest transactions. Notes receivable from participants are also considered party-in-interest transactions.

Note 9 - Risks and Uncertainties

The Plan provides for various investment options in investment securities. Investment securities, in general, are exposed to various risks, such as interest rate, credit and overall market volatility. Due to the level of risk associated with certain investment securities, it is reasonably possible that changes in the values of investment securities will occur in the near term which could materially affect the amounts reported in the statements of net assets available for benefits.
