Compensation Discussion and Analysis

Our compensation discussion and analysis provides a detailed description of our executive compensation philosophy, plans and programs, and the factors used by the Compensation Committee for determining 2025 compensation for our Named Executive Officers, identified pursuant to the rules of the SEC. For fiscal year 2025, the following executive officers comprised Columbia Financial’s Named Executive Officers (collectively, our “NEOs”):

Executive Compensation Philosophy

The Compensation Committee is committed to providing competitive, market-based total compensation programs that are aligned with our short- and long-term business strategies, tied to the performance of Columbia Financial and aligned with the long-term interests of our stockholders. The Compensation Committee achieves these objectives by using a combination of base salary, incentive-based cash awards and long-term incentive equity awards. Columbia Financial believes this mix of these compensation elements provides Columbia Financial’s NEOs with compensation that is reasonable and competitive within Columbia Financial’s market area, consistent with prudent banking practices, and also appropriately reflects Columbia Financial’s performance and the individual’s contributions to that performance.

Columbia Financial’s compensation philosophy recognizes the importance of individual achievements while also emphasizing overall corporate achievements. As such, our short-term and long-term incentive programs are heavily weighted toward the achievement of specific corporate goals.

In order to achieve these goals and consistent with our philosophy to provide a target reward when Columbia Financial meets its goals, our compensation program is comprised of four components: base salary, annual short-term cash incentives, long-term equity incentive compensation and benefit programs.

Elements of 2025 Executive Compensation Program

The various elements of our 2025 compensation program are intended to reflect our compensation philosophy and: (i) provide an appropriate level of financial certainty through fixed compensation, (ii) ensure that a significant portion of the compensation program is at-risk based on performance, (iii) ensure that at least 50% of equity compensation is at-risk based on performance, and (iv) create a balance of short-term and long-term incentives.

Compensation Tied to Performance

Consistent with our philosophy that a significant portion of the pay of our Named Executive Officer is at-risk compensation, we align the compensation of our executives with the interests of our stockholders by ensuring that a majority of our executives’ pay is at risk and depends on performance.

2025 CEO Target Compensation		2025 NEO Target Compensation

“Say on Pay Vote” Results

On June 6, 2025, stockholders of Columbia Financial voted on a non-binding resolution to approve the compensation for the NEOs, commonly referred to as a “Say on Pay” vote. The resolution was approved with an affirmative vote of 99.2% of votes cast, which reflects a strong vote of confidence in our executive compensation program and practices.

Our Executive Compensation Program

Our 2025 executive compensation program was based on the compensation philosophy adopted by our Compensation Committee and reflected the advice of the Compensation Committee’s independent compensation consultant. The Compensation Committee is guided by the following key principles in determining the compensation structure for our executives:

8

Our Executive Compensation Governance and Practices

Role of Compensation Committee

The Compensation Committee is made up of independent directors as required under the Nasdaq listing rules. Details on the Compensation Committee’s functions are described in the Compensation Committee’s charter, which has been approved by the Board and is available on our Investor Relations website.

The Compensation Committee has the authority to obtain advice and assistance from internal or external legal, human resources, accounting or other experts, advisors, or consultants as it deems desirable or appropriate. The Compensation Committee has sole authority to retain and terminate any compensation consultant and to approve the fee arrangements and the terms of engagement. For 2025, the Compensation Committee engaged an independent compensation consultant, which specializes in executive compensation.

During 2025, the Compensation Committee reviewed and approved all aspects of the compensation plans and policies applicable to the NEOs, including participation and performance measures. In carrying out its duties, the Compensation Committee considered the relationship of corporate performance to total compensation, set salary and incentive compensation levels, and reviewed the adequacy and effectiveness of various compensation and benefit plans. The Chair of the Compensation Committee reported the committee actions to the Board following each committee meeting.

Role of the CEO

The Compensation Committee worked closely with Mr. Kemly to review and discuss his recommendations for the NEOs and other executive officers. The Compensation Committee also considered the market and peer group analysis provided by the compensation consultant to assess market practices, the mix of fixed and variable compensation, and the levels of compensation for each named executive officer. In consultation with Mr. Kemly, the Compensation Committee determined to increase base salaries for the NEOs in 2025 based on individual performance and to better align base salaries with market median levels.

The Compensation Committee reviewed and accepted the self-evaluation (including relevant quantitative and qualitative accomplishments) of Mr. Kemly for the 2025 calendar year and provided feedback to Mr. Kemly. The Compensation Committee used this evaluation in making compensation decisions concerning Mr. Kemly and, as recommended by the Chair of the Compensation Committee for the 2025 calendar year, determined to increase Mr. Kemly’s base salary based on individual performance, general market movement in base salaries anticipated for 2025, and to better align base salary with the market median. Mr. Kemly does not make recommendations with respect to his own compensation or participate in the deliberations regarding the setting of his own compensation. Decisions related to Mr. Kemly’s 2025 compensation opportunities were made independently by the committee in consultation with its independent compensation consultant.

Role of Management

Members of our senior management team attend regular meetings in which executive compensation, Company performance, individual performance and competitive compensation levels and practices are discussed and evaluated. Only the Compensation Committee members can vote on decisions regarding NEO compensation.

The Compensation Committee believes that even the best advice of a compensation consultant or other outside advisors must be combined with the input from senior management and the Compensation Committee’s own individual experiences and judgment to arrive at the proper alignment of compensation philosophy, programs, and practices. Members of senior management worked with the Compensation Committee to provide perspectives on reward strategies and how to align those strategies with Columbia Financial’s business and management retention goals. They provided feedback and insights into the effectiveness of Columbia Financial’s compensation programs and practices. The Compensation Committee looked to the CEO, other members of executive management, and outside legal counsel for advice in the design and implementation of compensation plans, programs, and practices. In addition, the chief executive officer, and other members of executive management at times attended portions of Compensation Committee meetings to participate in the presentation of materials and to discuss management’s point of view regarding compensation issues.

Role of Independent Compensation Consultant

The Compensation Committee has retained the services of an independent compensation consultant, Pearl Meyer (“Pearl Meyer”) since 2022, to perform a competitive assessment of Columbia Financial’s executive and non-employee director compensation programs, as well as to provide guidance on the changing regulatory environment governing executive compensation. The annual

9

executive and director assessments include, but are not limited to, an assessment of Columbia Financial’s financial performance relative to its peers, an assessment of Columbia Financial’s compensation program compared to its peers, recommendations for total cash compensation opportunities (base salary and cash incentives), and a comparative benchmark study of executive compensation and non-employee director compensation. Since 2022, Pearl Meyer has assisted the Compensation Committee in developing an annual long-term performance-based equity incentive program for the NEOs.

Representatives of Pearl Meyer attended Compensation Committee and Board meetings during 2025, upon request, to review compensation data and participate in general discussions on compensation and benefits for the NEOs and the board members. While the Compensation Committee considered input from its compensation consultant when making compensation decisions, the Compensation Committee’s final compensation decisions reflect many factors and considerations.

The Compensation Committee considered the independence of Pearl Meyer under applicable SEC and Nasdaq listing rules and concluded there was no conflicts of interest with respect to the compensation consultant.

Peer Group and Benchmarking

The Compensation Committee believes benchmarking relative to our peers is a useful method to gauge both the compensation level and compensation mix for executives within competitive job markets that are relevant to Columbia Financial.

Competitive benchmarking is one of many factors considered by the Compensation Committee in making executive compensation decisions. The Compensation Committee generally reviews data gathered from the proxy statements of our peer group (as defined below) as well as industry surveys for benchmarking purposes in its review and analysis of base salaries, discretionary bonuses and short-term and long-term cash incentives, and equity grants to establish our executive compensation program. The Compensation Committee reviews the peer group annually and updates the peer group as appropriate to ensure that the peer group continues to consist of financial institutions with business models and demographics and a reasonable range of financial performance similar to Columbia Financial.

Pearl Meyer, at the request of the Compensation Committee, conducted a benchmarking study of NEO cash and equity compensation with respect to Columbia Financial’s peer group for the Compensation Committee to utilize in reviewing and approving 2025 compensation for the NEOs.

The Compensation Committee considered the following factors in reviewing its peer group: total assets, net income, ROE, ROAA, EPS, market capitalization, non-interest income, efficiency ratio, loan to asset ratio, loan to deposit ratio, number of full-time employees, and net income per employee. For purposes of reviewing and approving 2025 executive compensation, the Compensation Committee selected publicly traded financial institutions from the Northeast and Mid-Atlantic regions. The median asset size of the peer group was $13.3 billion as of June 30, 2024, placing Columbia Financial at slightly above the 25^th percentile in asset size, with an asset size on June 30, 2024 of $10.8 billion.

The peer group approved by the Compensation Committee for setting executive compensation for 2025 included the following 22 banks, all of which were used in the prior year.

10

The peer group was also utilized by the Compensation Committee for purposes of determining compensation of non-employee directors for 2025.

Timing of Executive Compensation Decisions

The Compensation Committee meets throughout the year to, among other things, discuss matters related to executive pay, including the say-on-pay vote results from its annual meeting of stockholders and the reports issued by the proxy advisory firms. At several meetings a year, the Compensation Committee receives input and reports from its independent compensation consultant on best practices for executive pay and emerging trends. In September of each year, the Compensation Committee typically reviews benchmarking data for the NEOs to determine whether any changes should be made to NEO base pay in the coming year. In June of each year, the Compensation Committee reviews the benchmarking data for the peer group to determine whether any changes should be made to the compensation structure of non-employee director compensation. The Compensation Committee also reviews the peer group composition once each year and makes revisions as determined necessary. In December 2024, the Compensation Committee approved the performance measures and corporate goals for the 2025 PAIP. In March 2025, the Compensation Committee approved the 2025-2027 LTIP metrics and goals.

2025 Compensation

Base Salary

Our NEO base salaries are set at levels that are intended to reflect the competitive marketplace in attracting, retaining, motivating, and rewarding high performing executives. In determining base salaries, the Compensation Committee considers the following elements: (i) individual performance based on experience and scope of responsibility, (ii) non-financial performance indicators including strategic developments for which an executive has responsibility and managerial accountability, (iii) compensation paid by peers, functionality of the executive management team, (iv) economic conditions in Columbia Financial’s market areas, and (v) analyses or guidance from independent consultants during the annual review process. The base salaries are intended to compensate the NEOs for the day-to-day services performed for Columbia Financial and Columbia Bank.

In establishing base salaries for our NEOs for 2025, the Compensation Committee reviewed the factors discussed above and determined to increase base salaries of the NEOs for 2025. Below are the NEO base salaries for 2024 and 2025.

Annual Incentive Compensation

Performance Achievement Incentive Program. We maintain an annual cash incentive program — the Performance Achievement Incentive Program (“PAIP”) — that is designed to align the interests of our employees with the overall performance of Columbia Financial. All exempt employees (excluding commissioned employees), including the NEOs, are eligible to participate in the PAIP, subject to certain eligibility requirements. A participant is eligible to earn a target incentive award for a calendar year defined as a percentage of the participant’s base salary. For 2025, the participant’s target incentive opportunity was based on achievement of a combination of overall Company, Bank, department/team, and individual performance goals. Awards to the NEOs are approved by the Compensation Committee in March following the end of the prior fiscal year.

When designing the 2025 PAIP and when considering whether the target performance metrics for a payout under the 2025 PAIP are achieved, the Compensation Committee had the discretion to take into account categories of significant, unplanned and unusual items that would be excluded from the performance metrics, whether the resulting impact was positive or negative, because they distort our operating performance. This practice, which is consistent with the practices of peer group companies, ensures that our executives will not be unduly influenced in their day-to-day decision-making because they would neither benefit, nor be penalized, as a result of certain unexpected and uncontrollable events or strategic initiatives that may positively or negatively affect the performance metric in the short-term.

11

The performance measures for the 2025 PAIP included the same corporate goals for each NEO and specific individual goals depending on the individual roles and responsibilities of each NEO, with each NEO’s individual scorecard setting forth the weightings assigned to each performance measure. The corporate goals utilized for 2025 did not change from those utilized for the 2024 PAIP, while individual goals did change for 2025 based on Columbia Financial’s department priorities for 2025.

The following table summarizes the thresholds, targets, and maximum parameters and actual 2025 performance for each of the applicable financial metrics selected under the 2025 PAIP:

The weighting assigned to each NEO in the categories that are applicable to them are set forth below:

12

For purposes of determining the level of achievement for each of the performance measures under the 2025 PAIP, the Compensation Committee reviewed the applicable financial metrics, as derived from our 2025 financial results, and the individual and department metrics. For the 2025 performance year, the Compensation Committee certified achievement of the three pre-established corporate performance measures reflected in the table above that were met for the CEO and each of the other NEOs.

After review and discussion, the successful execution of certain individual and departmental strategic objectives in 2025 coupled with achieving all three of the corporate goals resulted in payouts ranging between 82.72% and 90.30% of each NEO’s target 2025 PAIP opportunity, as is set forth below.

13

Long-Term Incentive Compensation

In March 2025, the board of directors of Columbia Financial approved the 2025 Long-Term Incentive Program (“LTIP”), as recommended by the Compensation Committee. Under the 2025 LTIP, long-term incentives are issued under the terms of our 2019 Equity Incentive Plan (the “2019 Equity Plan”). The target long-term incentive opportunity for each NEO under the 2025 LTIP was allocated among performance-based restricted stock (“PRSA”) (50%) and time-based vested nonqualified stock options (“NQSO”) (50%) as follows:

2025 – 2027 Performance Restricted Stock Awards. We grant PRSAs to our executives to align pay and long-term financial performance. The PRSAs have a three-year performance period, which will be measured over the period January 1, 2025 through December 31, 2027, with cliff vesting following the end of the performance period. Under the 2019 Plan and the applicable award agreements, the PRSAs are forfeited upon the executive’s termination of employment prior to the settlement date, which occurs after the close of the performance period. The awards vest at 50% of target upon the executive’s termination of employment by reason of death or disability with remainder of the PRSAs forfeited.

For the 2025 LTIP, the Compensation Committee retained one of the performance metrics for the 2025 LTIP as was used for the 2024 LTIP: Absolute Core Bank Return on Assets (“ROAA”). The second performance metric for the 2025 LTIP was Relative Stock Price Appreciation. ROAA will be calculated on a year-by-year basis based on annual performance targets, with the final metric calculated based on the average of the three years performance in the measurement period. ROAA is defined as the ratio that is derived by dividing Columbia Bank’s core net income by its total average assets for each fiscal year of Columbia Bank during the performance period, as publicly reported by Columbia Bank. ROAA is weighted at 60%. The Relative Stock Price Appreciation metric will be calculated based on the change in stock price from the beginning of the three-year performance period to the end of the three-year performance period as compared to Columbia Financial’s compensation peer group. The Relative Stock Appreciation metric is weighted at 40%.

The Compensation Committee believes that use of the ROAA metric facilitates alignment of the incentive awards grants with achievement of Columbia Bank’s targets for growth in earnings, over the three-year period. The Relative Stock Appreciation metric creates alignment with Columbia Bank’s strategic plan to create alignment between Columbia Bank’s strategic plan and stockholder interests as reflected in Columbia Financial’s relative stock price growth, as well as to benchmark this progress against peer banks.

At the end of the three-year performance period, our NEOs can earn between 0% and 150% of the target number of PRSAs granted based on the level of achievement of the two metrics. Payouts for intermediate performance level will be determined using straight-line interpolation. PRSA awards for the 2025-2027 performance period will be settled in the first quarter of 2028, following completion of Columbia Financial’s 2027 audited financial statements and review of final peer group financial results.

Stock Options. 2025 LTIP non-qualified stock option grants vest in equal installments over three years commencing on March 3, 2025, subject to continued service with Columbia Financial or its subsidiaries.

Results of 2023-2025 Performance-Based Restricted Stock Awards

The three-year performance period for the 2023-2025 PRSAs concluded on December 31, 2025. Payout of the award was based on Core Bank Return on Assets (“ROAA”) and Relative Core Bank Efficiency Ratio for the three-year performance period.

ROAA was calculated on a year-by-year basis based on annual performance targets, with the final metric calculated based on the average of the three-years performance period. ROAA was defined as the ratio that is derived by dividing Columbia Bank’s net income by its total average assets for each fiscal year of Columbia Bank during the performance period, as publicly reported by the Columbia Bank. ROAA was weighted at 60%. The Relative Core Bank Efficiency Ratio was calculated based on the average performance of Columbia Bank over the three-year performance period relative to the efficiency ratios achieved by the companies in

the KBW Nasdaq Regional Bank Index, as fixed at January 1, 2023. The Efficiency Ratio was calculated by dividing Columbia Bank’s non-interest expense by the sum of Columbia Bank’s net interest income plus non-interest income for each fiscal year of Columbia Bank or portion thereof in the performance period, as publicly reported by Columbia Bank. The Efficiency Ratio is weighted at 40%.

For the 2023-2025 performance period, the Efficiency Ratio metric was not achieved and the average performance for Core ROAA metric was achieved at 42%, which resulted in a total payout at 25%. Payouts for the 2023-2025 performance period will be made upon the vesting date of May 1, 2026.

The following table lists the number of shares to which our NEOs became vested at the end of the 2021-2023 performance cycle.

Other Compensation Programs and Policies

Retirement Benefits and Deferred Compensation

We maintain broad-based tax-qualified employee stock ownership and tax-qualified 401(k) plans. Generally, all employees of Columbia Financial are eligible to participate in these plans, including the NEOs. We also maintain a tax-qualified pension plan, which plan was closed to new participants effective October 1, 2018.

In addition to the tax-qualified plans described above, we provide our NEOs and other highly compensated employees with benefits under a nonqualified retirement and deferred compensation plans, as described below.

See the narrative accompanying the pension benefit tables and nonqualified deferred compensation tables for details regarding these plans as well as the discussion of such plans below under “Executive Compensation” below.

Other Benefits

We provide our NEOs with a set of core benefits that are generally available to our other full-time employees (e.g., coverage for medical, dental, vision care, prescription drugs, and basic life insurance and long-term disability coverage), plus voluntary benefits that a NEO may select (e.g., supplemental life insurance).

Life Insurance Benefits. We maintain supplemental life insurance agreements with each of the named executive officers, other than Ms. Schlesinger. Pursuant to those agreements, the executive officer’s designated beneficiary will be entitled to share in the death proceeds payable under one or more life insurance policies owned by us in the event of the executive’s death while the agreement remains in effect. The amount payable to the named executive officers’ beneficiaries, other than Mr. Kemly, is one and one-half times base salary. For Mr. Kemly the benefit payable is three times his base salary. These benefits are in addition to the basic life insurance Columbia Financial provides to all full-time employees, limited to $1.0 million. The supplemental life insurance agreements will terminate if the executive officer has a separation from service, other than as a result of the executive officer’s disability or retirement. The Summary Compensation Table includes the taxable income associated with this benefit in the column labeled All Other Compensation.

15

Perquisites

We annually review the perquisites that we make available to our named executive officers. The primary perquisites for these individuals may include automobile allowances and mobile phone charges. See “Executive Compensation — Summary Compensation Table” for detailed information on the perquisites provided to our NEOs.

Employment Agreements

The Compensation Committee believes that employment agreements are necessary to attract and retain qualified executives and ensure the stability of our executive management team. Our employment agreements with our NEOs generally set forth the terms of the executive’s employment with Columbia Financial and also promise severance benefits if the executive is involuntarily terminated without cause or, in some cases, if the executive voluntarily terminates his or her employment for good reason. The retention of key management is essential to and in our stockholders’ best interests. The Compensation Committee believes reasonable severance benefits help ensure the continued dedication and efforts of management without undue concern for or distraction by their personal, financial and employment security. Similarly, in the context of a potential change in control transaction, the Compensation Committee believes that employment agreements effectively motivate executives to remain engaged and strive to create stockholder value, despite the risk of job loss or the loss of equity vesting opportunity. In addition, these severance arrangements are necessary to attract and retain qualified executives who may have other job alternatives that may appear to them to be less risky absent these arrangements. For a detailed description of Columbia Financial’s employment agreements with our NEOs, please see the section entitled “Summary of Executive Employment Agreements and Potential Payments upon Termination or Change in Control.” Columbia Financial has entered into new employment agreements with our executive management team in connection with Columbia Bank’s proposed second-step conversion, other than Mr. Kemly whose existing employment agreement will be assumed by Columbia Financial, Inc., a newly formed Maryland holding company that will become the holding company for Columbia Bank upon the completion of the second-step conversion. Columbia Financial, Inc. (a Maryland corporation)and Columbia Bank are also parties to the new agreements. The new employment agreements are substantially the same as the current employment agreements with Columbia Financial. The primary change from the current agreements was to have the severance terms for all executive officers be the same whereas, in the prior agreements, the severance terms varied among the executives.

Tax Deductibility of Executive Compensation

To the greatest extent possible, we structure our compensation programs in a tax-efficient manner. The Compensation Committee believes that tax deductibility is but one factor to consider in developing an appropriate compensation package for executives. As such, the Compensation Committee reserves and will exercise its discretion in this area to design a compensation program that serves the long-term interests of Columbia Financial, but which may not qualify for tax deductibility under Section 162(m) of the Internal Revenue Code.

Executive Compensation Policies

Recoupment and Clawback Policies. Columbia Financial has a policy for the recoupment of incentive compensation (the “Recoupment Policy”), which was formerly referred to as our Clawback Policy, and which was updated in 2023 to comply with the Exchange Act and the Nasdaq Listing Rules.

The Recoupment Policy provides for the prompt recovery of certain excess incentive-based compensation received during an applicable three-year recovery period by current or former executive officers in the event we are required to prepare an accounting restatement due to material noncompliance with any financial reporting requirement under the securities laws. Triggering events include accounting restatements to correct an error in previously issued financial statements that is material to such previously issued financial statements, or that would result in a material misstatement if the error were corrected in the current period or left uncorrected in the current period. Excess incentive-based compensation for these purposes generally means the amount of incentive-based compensation received by such executive officer that exceeds the amount of incentive-based compensation that would have been received by such executive officer had it been determined based on the restated amounts, without regard to any taxes paid. Incentive- based compensation potentially subject to recovery under the Recoupment Policy is in general limited to any compensation granted, earned, or vested based wholly or in part on the attainment of one or more financial reporting measures.

16

Based on the foregoing risk assessment conducted for 2025, the Compensation Committee concluded that our incentive compensation plans do not create significant inappropriate or unintended risk to Columbia Financial. Further, it determined that our incentive compensation arrangements provide incentives that do not encourage risk-taking beyond Columbia Financial’s ability to effectively identify and manage significant risks; that are compatible with effective internal controls and our risk management practices; and that are supported by strong governance and the oversight and administration of the Compensation Committee and the board of directors.

Compensation Committee Interlocks and Insider Participation

None of the members of the Compensation Committee of Columbia Financial is or has been an officer or employee of Columbia Bank, and no executive officer of Columbia Bank served on the compensation committee or board of any company that employed any member of Columbia Financial’s Compensation Committee or board of directors. None of the members of the Compensation Committee had a relationship that would require disclosure under Item 13 of this Form 10-K/A, except as may be described under that item of this Form 10-K/A.

Pension Benefits

Tax-Qualified Pension Plan. The Columbia Bank Retirement Plan (“Pension Plan”) is a tax-qualified defined benefit pension plan that covers approximately 841 eligible current employees, former employees, and retirees of Columbia Financial. All of the NEOs, other than Mr. Lewis, participate in the Pension Plan. If a participant elects to retire upon the attainment of age 65, and the participant was hired prior to July 1, 2005, the plan provides that the participant’s normal retirement benefit will equal 2% of his or her average annual compensation for each plan year and month of service, up to a maximum of 45 years. If a participant elects to retire upon attainment of age 65, and the participant was hired on or after July 1, 2005, the plan provides that the participant’s normal retirement benefit will equal 1.8% of his or her average annual highest compensation over five consecutive years for each plan year and month of service, up to a maximum of 45 years. Participants who have attained age 55 and have completed 10 years of service may retire early. If the participant was hired prior to July 1, 2005, his or her benefit will be reduced by 3.0% for each year of early commencement between age 55 and 65; if the participant was hired on or after July 1, 2005, his or her benefit will be reduced by 1/15th for each year of early commencement between age 60 and 65 and an additional 1/30th for each year of early commencement between age 55 and 60. Participants become fully vested in their accrued plan benefit after five years of service. Under the plan, “average annual compensation” is defined as the average of a participant’s compensation for the period of five consecutive years during which his or her compensation was the highest. The Pension Plan was closed to new participants effective October 1, 2018. The Pension Plan was overfunded on December 31, 2025, with assets representing 204.2% of our benefit obligation at that date.

Retirement Income Maintenance Plan. The Columbia Bank Retirement Income Maintenance Plan (“RIM”) is a nonqualified and unfunded defined benefit retirement plan that provides supplemental retirement benefits to certain highly compensated employees of Columbia Financial and its subsidiaries whose benefits under the Pension Plan are limited due to the restrictions of Section 415 and/or Section 401(a)(17) of the Internal Revenue Code. All of the NEOs who participate in the Pension Plan also participate in the RIM. A participant’s benefit under the RIM is equal to the excess of (i) the benefit that would be payable to the participant in accordance with the terms of the tax-qualified pension plan disregarding the limitations imposed by Section 415 and Section 401(a)(17) of the Internal Revenue Code, less (ii) the benefit actually payable to the participant under the Pension Plan after taking such limitations into account. A participant becomes vested in his or her RIM benefits upon satisfying the requirements for early retirement (attaining age 55 while employed and completing 10 years of service) or normal retirement (attaining age 65 while

22

employed and completing five years of service). A participant’s vested RIM benefit will be paid at the time and in the form elected by the participant; the default time and form of payment is a life annuity with a minimum of 120 monthly payments commencing on the first day of the month following the month in which the participant separates from service, provided that if the participant is a “specified employee” for purposes of Section 409A of the Internal Revenue Code on the date of the participant’s separation from service, payment will be delayed for six months following the participant’s separation from service.

Pension Benefits Table. The following table shows the actuarial present value of the accumulated benefit under our tax-qualified pension plan and the RIM, along with the number of years of credited service under the respective plans, for each of our named executive officers.

Nonqualified Deferred Compensation

Supplemental Executive Retirement Plan. The Columbia Bank ESOP Supplemental Executive Retirement Plan (“ESOP SERP”) is a nonqualified and unfunded defined contribution retirement plan that provides supplemental retirement benefits related to its tax-qualified employee stock ownership plan. The ESOP SERP provides benefits to eligible officers of Columbia Financial and its subsidiaries designated by the Board that cannot be provided under the tax-qualified employee stock ownership plan but for the eligibility requirements of the plans or limitations imposed by the Internal Revenue Code. All NEOs are eligible to participate in the ESOP SERP. An NEO becomes vested in these benefits in 25% increments after completing two, three, four and five years of service with Columbia Financial. In addition to providing benefits that would otherwise be lost because of eligibility requirements or the Internal Revenue Code limitations on tax-qualified plans, the ESOP SERP also provides a supplemental benefit upon a change of control prior to the scheduled repayment of the tax-qualified employee stock ownership plan loan. Under the terms of the ESOP SERP, each NEO is eligible to receive a cash payment in the event of a change in control equal to the dollar value of the stock benefit the NEO would have received under the tax-qualified employee stock ownership plan and ESOP SERP had the executives remained employed throughout the term of the loan, less the shares of common stock allocated under the tax-qualified employee stock ownership plan and ESOP SERP on the NEO’s behalf. The supplemental change in control benefits under the ESOP SERP are nonforfeitable and distributable upon termination of employment for any reason.

Non-Qualified Savings Income Maintenance Plan. The Columbia Bank Savings Income Maintenance Plan (the “SIM”) is a non-qualified and unfunded defined contribution retirement plan for the benefit of certain highly compensated employees of Columbia Financial and its subsidiaries. All NEOs are eligible to participate in the SIM. Under the SIM, a participant may defer between 3% and 13% of the participant’s compensation above the salary limit imposed by Section 401(a)(17), reduced by the amount of Federal Insurance Contribution Act taxes that the participant must pay in a plan year with respect to such compensation. In addition, Columbia Financial may make matching contributions equal to a portion of a participant’s compensation deferred under the SIM. For 2025, Columbia Bank made matching contributions in an amount equal to 100% of up to the first 3% of a participant’s compensation in

excess of $350,000 that the participant deferred under the SIM including all of the NEOs. Participants earn a return on their notional account balances based on investment in phantom investment funds (like those available under the 401(k) Plan) selected by participants. The SIM does not guarantee a rate of return and none of the investment funds provide above market earnings. Participants are immediately 100% vested in their account balances attributable to compensation deferral contributions. Participants generally become vested in their account balances attributable to matching contributions in installments — 25% after two years of

23

service, 50% after three years of service, 75% after four years of service and 100% after five years of service — and become 100% vested upon death. A participant’s vested account balance will be distributed to the participant in a single lump sum upon the earlier of the participant’s separation from service or a change in control of Columbia Bank. If distribution is triggered by separation from service, it will be made on the first day of the month next following the two-month anniversary of the participant’s separation from service, provided that if the participant is a “specified employee” for purposes of Section 409A of the Internal Revenue Code on the date of the participant’s separation from service, payment will be delayed for six months following the participant’s separation from service. If distribution is triggered by a change in control, it will be made on the first day of the month next following the change in control.

Stock-Based Deferral Plan. The Columbia Bank Stock-Based Deferral Plan provides eligible key executives and members of the board of directors with the opportunity to elect to defer compensation received from Columbia Bank for their services and make contributions to the Stock-Based Deferral Plan which are credited to the individual’s deferral account in the form of phantom shares of Columbia Financial common stock. Pursuant to the Stock-Based Deferral Plan, eligible employees can defer up to 100% of their salary, bonus or cash-based incentive compensation and directors can defer up to 100% of their cash retainers. Assets in the Stock-Based Deferral Plan are held in a separate Rabbi Trust to pay Plan benefits. In order to maintain the Plan’s tax-deferred status, Rabbi Trust assets are subject to the claims of creditors of Columbia Financial in the event of its insolvency.

Nonqualified Deferred Compensation Table. The following table discloses contributions made under the SIM and the ESOP SERP for each named executive officer in 2025, along with the earnings and balances on each executive’s account as of December 31, 2025.

Summary of Executive Employment Agreements and Potential Payments Upon Termination or Change in Control

Columbia Financial previously entered into two-year employment agreements with Messrs. Kemly, Gibney, Klimowich, Lewis, and Ms. Schlesinger. Under these agreements, the Board may extend the terms of the employment agreements with the NEOs annually for another 12-month period unless the NEO gives notice of non-renewal at least 60 days prior to such extension. The Compensation Committee annually reviews the NEO’s base salaries. In addition to base salary, the agreements provide that the NEOs shall be eligible to participate in the short-term and long-term incentive compensation plans of Columbia Bank. Each NEO shall also be entitled to continue participation in any fringe benefit arrangements in which he or she was participating on the effective date of the employment agreement. In addition, the agreements provide for reimbursement of reasonable travel and other business expenses incurred in connection with the performance of the NEO’s duties.

24

Columbia Financial, Columbia Financial, Inc. (a Maryland corporation) and Columbia Bank have entered into new, two year employment agreements with Messrs. Gibney, Klimowich, Lewis and Ms. Schlesinger. The primary purpose of the new agreements was to make the terms of the agreements consistent among the NEOs, particularly with respect to severance provisions. Mr. Kemly’s current employment agreement will be assumed by Columbia Financial, Inc. (a Maryland corporation) upon the completion of Columbia Bank’s second-step conversion.

This summary and the potential termination payments are based on the prior employment agreements, which were in effect as of December 31, 2025.

Termination Without Cause or Resignation for Good Reason

If a NEO’s employment is terminated by Columbia Financial or Columbia Bank during the term of the agreement, without cause, including a resignation for good reason (as defined in the agreement), but excluding termination for cause or due to death, disability, retirement, the executive would be entitled to a payment equal to a multiple (three times for Mr. Kemly and two times for Messrs. Gibney, and Klimowich and one times for Mr. Lewis and Ms. Schlesinger) of the sum of: (i) his or her annual base salary plus (ii) his or her target annual bonus in effect on the termination date. The severance payment shall be paid to the NEO as salary continuation in substantially equal installments over the thirty-six, twenty-four or twelve-month period, respectively, in accordance with Columbia Bank’s customary payroll practices, subject to the receipt of a signed release of claims from the NEO within the time frame set forth in the agreement. Assuming the NEO elects continued medical, vision and dental coverage under COBRA, Columbia Bank will reimburse the executive the amount equal to the monthly COBRA premium paid by the NEO for such coverage less the active employee premium for such coverage for a period of 36 months, in the case of Mr. Kemly, and 24 months, in the case of Messrs. Gibney, and Klimowich and 12 months in the case of Mr. Lewis and Ms. Schlesinger or such lesser period as may be required under COBRA.

Termination Without Cause or Resignation for Good Reason upon a Change in Control

If a NEO’s employment is terminated during the term of the agreement by Columbia Financial or Columbia Bank without cause, including a resignation for good reason (as defined in the agreements), within 24 months after a change in control (as also defined in the agreements), the NEO would be entitled to a payment equal to a multiple of three times (two times in the case of Ms. Schlesinger) of the sum of: (i) his or her annual base salary (or his base salary in effect immediately before the change in control, if higher) plus (ii) his or her annual target bonus (or his target bonus in effect immediately before the change in control, if higher). The severance payment shall be paid to the NEO within sixty days of the termination date in a single lump sum payment. The payment shall also include a sum equal to his or her prior year bonus in a lump sum on the date on which the annual bonus would have been paid to NEO but for NEO’s termination of employment. In addition, each NEO shall receive a lump sum payment equal to the cost of providing continued medical, vision and dental coverage for 36 months following termination less the active employee charge for such coverage in effect on the termination date.

Definition of Good Reason

For purposes of the NEO’s ability to resign and receive a payment under the agreement, “good reason” would include the occurrence of any of the following events: (i) a material reduction in the NEO’s base salary or target bonus under the cash incentive plans, if applicable, except for reductions proportionate with similar reductions to all other members of the executive leadership team; (ii) a material adverse change in NEO’s position that results in a demotion in the NEO’s status within Columbia Financial or Columbia Bank; (iii) a change in the primary location at which the NEO is required to perform the duties of his employment with Columbia Financial and Columbia Bank to a location that is more than 30 miles from the location of Columbia Bank’s headquarters as of the date of the agreement; or (iv) a material breach by Columbia Financial or Columbia Bank of any written agreement between the NEO, on the one hand, and any of Columbia Financial and Columbia Bank or any other affiliate of Columbia Financial, on the other hand, unless arising from the NEO’s inability to materially perform his or her duties under the agreement.

Best Net Benefits

Section 280G of the Internal Revenue Code provides that severance payments that equal or exceed three times an individual’s base amount are deemed to be “excess parachute payments” if they are contingent upon a change in control. An individual’s base amount is generally equal to an average of the individual’s taxable compensation for the five taxable years preceding the year a change in control occurs. The employment agreements with our NEOs provide for a “best net benefits” approach in the event that severance benefits under the agreements or otherwise result in “excess parachute payments” under Section 280G. The best net benefits approach reduces an NEO’s payments and benefits to avoid triggering the excise tax if the reduction would result in a greater after-tax amount to the NEO compared to the amount the NEO would receive net of the excise tax if no reduction were made.

25

Termination as a Result of Disability

Under the employment agreements, if an NEO’s employment terminates as a result of disability, the employment agreement will terminate and the NEO will receive an amount equal to one time the sum of his or her base salary and target bonus in effect on the termination date less the amount expected to be paid to the NEO under the Columbia Bank long term disability plan, payable as salary continuation in substantially equal installments over a twelve-month period. For these purposes, disability will occur on the date on which the insurer or administrator of Columbia Bank’s long-term disability insurance determines that the NEO is eligible to commence benefits under such insurance. If the NEO dies while employed, (i) the NEO will remain entitled to life insurance benefits pursuant to Columbia Bank’s plans, programs, arrangements, and practices in this regard and (ii) Columbia Bank will pay to his or her designated beneficiary an amount equal to one time the sum of the NEO’s base salary and target bonus in effect on the termination date.

Treatment of Equity Awards in the Event of a Change in Control

Under the 2019 Equity Incentive Plan and the award agreements for the equity awards made to the NEOs, in the event of a change in control (as defined in the plan) and the involuntary separation of the NEO from service with Columbia Financial and its affiliates without cause within 12 months of the change in control and prior to the last vesting date for such awards, if such awards are not assumed by the surviving entity in the change in control, all such awards that are unvested at the time of the change in control will become immediately vested upon the effective date of the change in control.

Payments under Nonqualified Deferred Compensation Plans

As disclosed under “Nonqualified Deferred Compensation” above, under the terms of the ESOP SERP, an NEO will receive an additional cash payment in the event of a change in control equal to the benefit the NEO would have received under the Columbia Bank ESOP and the ESOP SERP had the NEO remained employed throughout the term of the ESOP loan, less the benefits actually provided under the Columbia Bank ESOP and ESOP SERP on the NEO’s behalf. The supplemental change in control benefits credited to NEO accounts under the ESOP SERP are nonforfeitable and will be distributed upon termination of employment for any reason. Distributions from the ESOP SERP (except for the supplemental ESOP SERP benefit in the event of a change in control) are not categorized as parachute payments and, therefore, do not count towards a participating executive’s limitation under Section 280G of the Internal Revenue Code.

Each NEO’s account balance under the SIM will become fully vested upon the NEO’s death. SIM benefits are described in more detail under “Pension Benefits Table.”

Messrs. Kemly, and Klimowich are vested in their RIM benefits, and they have each elected to receive payment of their accrued benefits under the RIM upon a change in control (as defined in the RIM). RIM benefits are described in more detail under “Pension Benefits.”
