Benefit Plans and Agreements 

Employment Agreement with Thomas L. Amell**.**   On July 17, 2019, Pioneer Bank entered into an employment agreement with Mr. Amell.  The employment agreement has an initial term that ends on December 31, 2021. The initial term will extend automatically for one additional year on January 1 of each year beginning January 1, 2020 unless either Pioneer Bank or Mr. Amell give notice no later than 30 days before the anniversary date that the term will not be renewed. At least 30 days prior to each anniversary date of the employment agreement, disinterested members of the board of directors of Pioneer Bank will conduct a comprehensive performance evaluation and review of Mr. Amell’s performance for purposes of determining whether to take action to not renew the employment agreement.

The employment agreement specifies Mr. Amell’s base salary, which currently is $651,182. The compensation committee of the board of directors (the “Compensation Committee”) may increase, but not decrease, Mr. Amell’s base salary.  In addition to the base salary, the agreement provides that Mr. Amell is eligible to participate in any bonus plan or arrangement of Pioneer Bank in which senior management is eligible to participate and/or may receive a bonus on a discretionary basis, as determined by the Compensation Committee. Mr. Amell is also entitled to participate in all employee benefit plans, arrangements and perquisites offered to employees

----

and officers of Pioneer Bank and the reimbursement of reasonable travel and other business expenses incurred in the performance of his duties with Pioneer Bank, including memberships in organizations as Mr. Amell and the board mutually agree are necessary and appropriate.

Pioneer Bank may terminate the executive’s employment, and Mr. Amell may resign, at any time with or without good reason.  In the event of Mr. Amell’s (1) termination without cause other than due to death or disability, or (2) voluntary resignation for good reason (a “qualifying termination event”), Pioneer Bank would pay Mr. Amell a cash lump sum payment equal to the base salary he would have earned had he remained employed for the greater of: (1) the remaining term of the employment agreement; or (2) 12 months (the “benefits period”).  In addition, Mr. Amell would receive non-taxable medical and dental insurance coverage under Pioneer Bank’s group health plan at the same cost-sharing arrangement in effect as of the date of determination during the benefits period or, if earlier, until Mr. Amell receives substantially comparable health and welfare coverage from another employer. A “good reason” condition for purposes of the employment agreement would include a material reduction in base salary, a material reduction in authority, duties or responsibilities associated with Mr. Amell’s position with Pioneer Bank, a relocation of Mr. Amell’s principal place of employment by more than 35 miles from Pioneer Bank’s main office or a material breach of the employment agreement by Pioneer Bank.

In the event Mr. Amell’s qualifying termination event occurs on or after a change in control of Pioneer Bancorp or Pioneer Bank, Mr. Amell would be entitled to (in lieu of the payments and benefits described in the previous paragraph) a severance payment equal to three times the sum of his: (1) base salary in effect as of the date of his termination or immediately prior to the change in control, whichever is higher; and (2) the highest annual cash bonus earned for the three most recently completed performance periods prior to the change in control.   Such payment will be made in a cash lump sum within 30 days following the Mr. Amell’s date of termination. In addition, Pioneer Bank (or its successor) will continue to provide Mr. Amell with life insurance and non-taxable medical and dental insurance coverage substantially comparable to the coverage provided to him immediately before his date of termination at no cost to Mr. Amell.  Such continued coverage will cease upon the earlier of: (1) 36 months after the date of termination; or (2) the date on which Mr. Amell becomes a full-time employee of another employer and receives comparable health and welfare benefits.

The employment agreement would immediately terminate upon the earlier of Mr. Amell’s voluntary resignation without good reason, death or disability, and Pioneer Bank would have no obligation to pay any additional severance benefits to Mr. Amell under the employment agreement.

Upon termination of employment (other than a termination in connection with a change in control), Mr. Amell will be required to adhere to one-year non-competition and non-solicitation restrictions set forth in his employment agreement.

Change in Control Agreements**.**  Pioneer Bank entered into individual change in control agreements with five other executive officers, including Frank C. Sarratori, Executive Vice President, Chief Administrative Officer, General Counsel and Corporate Secretary, Jesse Tomczak, Executive Vice President and Chief Banking Officer, and Patrick J. Hughes, Executive Vice President and Chief Financial Officer.  The change in control agreements have terms that initially end on December 31, 2020.  Each agreement will extend automatically for one additional year on January 1 of each year beginning January 1, 2020 so that the remaining term is two years unless either Pioneer Bank or the executive gives notice no later than 30 days before such anniversary date that the agreement will not be renewed. At least 30 days prior to each anniversary date of the change in control agreements, disinterested members of the board of directors of Pioneer Bank will conduct a comprehensive performance evaluation and review of each executive’s performance for purposes of determining whether to not renew the executive’s change in control agreement.  Notwithstanding the foregoing, in the event that Pioneer Bancorp or Pioneer Bank enters into a transaction that would be considered a change in control as defined under the agreements, the term of the agreements would extend automatically so that they would expire no less than two years beyond the effective date of the change in control.

In the event of the executive’s involuntary termination of employment other than for cause, disability or death, or voluntary resignation for “good reason” on or after the effective date of a change in control of Pioneer Bancorp or Pioneer Bank, each executive would be entitled to a severance payment equal to two times the sum of the executive’s: (1) base salary in effect as of the date of his termination or immediately prior to the change in control, whichever is higher; and (2) the highest annual cash bonus earned for the three most recently completed performance periods prior to the change in control.  Such payment will be made in a cash lump sum within 30 days following the executive’s date of termination.  In addition, Pioneer Bank (or its successor) will continue to provide each executive with life insurance and non-taxable medical and dental insurance coverage substantially comparable to the coverage provided to him or her immediately before the date of termination at no cost to the executive.  Such continued coverage will cease upon the earlier of: (1) 24 months after the date of termination; or (2) the date on which the executive becomes a full-time employee of another employer and receives comparable health and welfare benefits.

A “good reason” condition for purposes of each change in control agreement would include a material reduction in base salary, a material reduction in authority, duties or responsibilities associated with the executive’s position with Pioneer Bank, a relocation of the executive’s principal place of employment by more than 35 miles from Pioneer Bank’s main office or a material breach of the change in control agreement by Pioneer Bank.

Targeted Incentive Plan (TIP).  Pioneer Bank adopted the TIP for its executive officers who are approved annually by the board.  Each named executive officer is a participant in the TIP.  The TIP is designed to provide participants with incentives and motivation to increase Pioneer Bank’s profitability and growth while maintaining its safety and soundness.  The TIP provides annual incentive awards to participants based on overall bank-wide, department and/or individual performance goals established annually, which are determined by using performance history, peer data, market data and the Compensation Committee’s judgment based on previous experience and projected market conditions.  

Each participant can achieve annual incentive awards based on a percentage of base salary, depending on performance goals at certain percentages of achievement, ranging from 90% to 115% for the Chief Executive Officer and 90% to 110% for the other executive officers.  Each performance goal established is weighted.  The annual performance period under the TIP is a 12-month period ending on December 31 of each year (the “plan year”). The calculation of adjusted net income as applied to the performance goals for the plan year ended December 31, 2019 is net income under accounting principles generally accepted in the United States of America, excluding gains or losses on securities transactions and the contribution to the Pioneer Bank Foundation.  For the plan year ended December 31, 2019, the performance goals established were based on: (1) current year return on assets; (2) three-year return on assets; (3) core deposit growth; and (4) three-year return on assets compared to a peer group of all federally insured savings banks having assets between $300 million and $1.0 billion. The performance goals were equally weighted for each participant, except for the CEO, whose performance goals were weighted 15%, 40%, 15% and 30%, respectively, to be more focused on the long-term performance of Pioneer Bank. Furthermore, any annual incentive award payable under the TIP was contingent upon Pioneer Bank obtaining minimum performance goals related to net income and safety and soundness and the participant having satisfactory job performance during the plan year.  Each named officer’s annual incentive award opportunities for the plan year ended December 31, 2019, as a percentage of base salary, was 40%. 

Each participant’s annual incentive award is payable in a cash lump sum as soon as practicable following the completion of the plan year, provided, however, that such payment will be made no later than two and one-half months following the end of the plan year.  A participant must be actively employed on the last day of the plan year in order to receive the annual incentive award.  Based on the foregoing, Messrs. Amell, Sarratori and Hughes earned $127,236, $51,432 and $49,621, respectively, under the TIP for the plan year ended December 31, 2019 and such bonuses were paid to Messrs. Amell, Sarratori and Hughes in February, 2020. 

Board of Directors and Executive Employees Deferred Compensation Plan.  Pioneer Bank maintains the Pioneer Bank Board of Directors and Executive Employees Deferred Compensation Plan for directors and certain executives of Pioneer Bank who are designated to participate in the plan by the board.  Mr. Sarratori is the only named executive officer participating in the plan.  Participants may make an election on a deferral election form (the “election form”) to defer a portion the participants’ compensation, up to 100%.  Amounts deferred are credited to a bookkeeping account established in the name of each participant.  The participant’s account balance accrues earnings, as if the balance was invested in one or more investment funds as selected by the employer, in multiples of 1%.  Participants are always 100% vested in their deferral accounts.  Participants must elect on the participation agreements the form and timing of distribution at the time the participant makes the deferral election. If the participant fails to properly elect the time and form of distribution, the participant’s account will be designated as a separate account and will be paid in a lump sum.  Unless the participant has elected for his or her account balance to be payable while employed with Pioneer Bank, the participant’s account balance is generally distributed upon the earlier of death, disability or termination of employment.  

**Tax-Qualified Retirement Plans**

Pension Plan.  Pioneer Bank maintains The Retirement Plan of Pioneer Savings Bank, a qualified, tax-exempt non-contributory defined benefit plan (the “pension plan”) for employees of Pioneer Bank, excluding union employees and leased employees. Employees hired prior to September 1, 2019 are enrolled on January 1 or July 1 following the completion of one year of service and attainment of age 21.  Part-time employees are eligible if they have worked a minimum of 1,000 hours in their first year of employment or in any subsequent pension plan year.  Employee hired on or after September 1, 2019 are not eligible to participate in the pension plan.  Contributions to the pension plan are made to satisfy the actuarially determined minimum funding requirements according to the Employee Retirement Income Security Act of 1974, as amended (“ERISA”).  A participant becomes 100% vested in his or her accrued benefit under the pension plan after five years of service with Pioneer Bank.

Upon attainment of normal retirement date (age 65 for participants who entered the plan before October 1, 1988, or the later of age 65 or the fifth anniversary of participation in the plan for participants who entered the plan on or after October 1, 1988), the participant is entitled to a normal retirement benefit, which is an monthly benefit equal to 1/12 of the product of 2% of the participant’s average annual earnings, multiplied by the participant’s full and fractional years of service (up to a maximum of 30 years) earned before January 1, 2010, plus the product of 1.5% of the participant’s average annual earnings multiplied by the participant’s full and fractional years of service earned after December 31, 2009 (up to a maximum of 30 years reduced by years of service earned prior to January 1, 2010) payable for the life of the participant.  Alternative forms of payments include the actuarial equivalent of the normal retirement benefit paid in the form of a lifetime benefit, with a guaranteed minimum of 10 or 15 years, a 50%, 75% or 100% survivor lifetime benefit for the participant and his or her joint annuitant, and an annuity with the option to elect the form of survivor benefit which meets the requirements of Section 401(a)(9) of the Internal Revenue Code. 

If the participant has attained his or her early retirement date (the date on which the participant has completed 30 years of service or attainment of age 60 with 20 years of service) and elects the normal retirement benefit to commence prior to the normal retirement date, the participant would receive an early retirement benefit equal to the participant’s accrued pension benefit, reduced by 0.4166% for each of the first 60 months before the normal retirement date and 0.2083% for each additional month before the normal retirement date.  

If a participant terminates employment prior to the normal retirement date and early retirement date, the participant would be entitled to the participant’s vested accrued benefit, determined as of the date of termination of employment, payable as of the participant’s normal retirement date; provided, however, that if  the participant has completed 20 years of service for the normal retirement benefit, the participant may elect to begin benefit payments as of the first day of any month following the month in which the participant would have been eligible for early retirement if the participant had continued employment adjusted by the same factors as the early retirement benefit.  

401(k) Plan.  Pioneer Bank maintains the Pioneer Bank 401(k) Plan, which is a qualified, tax-exempt profit-sharing plan with a salary deferral feature under Section 401(k) of the Internal Revenue Code (the “401(k) Plan”).  All eligible employees may participate in the plan upon reaching age 21 and working for at least three months with respect to making elective salary deferrals and receiving all other employer contributions.  Eligible employees are permitted to make elective salary deferrals in an amount up to $19,500 (as indexed annually).  Eligible employees who have not made a salary deferral election automatically have withheld 6% of their salary deferred as a pre-tax contribution which will be invested in accordance with the plan’s investment policies.  Eligible employees may designate their salary deferrals as either pre-tax or after-tax Roth deferrals.

An employee may also contribute rollover contributions to the plan from another eligible retirement plan.  Employees who have attained age 50 before the end of a plan year are also eligible to make catch-up contributions during the year in an amount not to exceed $6,500 (as indexed annually).  All employee elective salary deferrals, catch-up contributions and “rollover” contributions are fully and immediately vested.  

In addition, Pioneer Bank currently makes an employer matching contribution for the amount a participant contributes as salary deferrals up to 100% of the amount contributed for the first 1% of the participant’s plan compensation plus 50% of the amount contributed between 1% and 6% of the participant’s plan compensation.  Pioneer Bank may also make discretionary qualified non-elective contributions.  Pioneer Bank may also make a discretionary pro-rata employer contribution each plan year.  

Employer matching contributions and employer discretionary pro-rata contributions are subject to a six-year vesting schedule, such that the participant vests in the first 20% of his or her account attributable to employer matching and profit-sharing contributions after two years of service and an additional 20% each year thereafter until fully vested after six years.  The qualified non-elective contributions are fully and immediately vested.  Generally, a participant is not entitled to an in-service distribution of his or her account balance until the participant attains age 59-1/2.  In addition, the 401(k) Plan permits loans to participants within the limits set forth in the Internal Revenue Code and according to loan procedures established by Pioneer Bank.  Participants are entitled to benefit payments upon termination of employment, disability or death.  Participants may elect that benefits be distributed in the form of a lump sum or in equal annual installments paid over a set of number of years.  Pioneer Bank has established an employer stock fund in the 401(k) Plan so that participants can acquire an interest in the common stock of Pioneer Bancorp through their accounts in the 401(k) Plan.  

Employee Stock Ownership Plan.  In connection with its mutual holding company reorganization and related stock offering, Pioneer Bank adopted an employee stock ownership plan (the “ESOP”) for eligible employees.  The named executive officers are eligible to participate in the ESOP just like other eligible employees.  Eligible employees who have attained age 21 on the first entry date commencing on or after the eligible employee’s completion of one year of service.

​

----

The ESOP trustee purchased, on behalf of the ESOP, 1,018,325 shares of Pioneer Bancorp common stock outstanding, funded with a loan from Pioneer Bancorp equal to the aggregate purchase price of the common stock.  The loan is repaid principally through Pioneer Bank’ discretionary contributions to the ESOP and any dividends payable on common stock held by the ESOP over the 20-year term of the loan.  The interest rate for the ESOP loan is the prime rate, as published in The Wall Street Journal.  The interest rate adjusts annually and is the prime rate on the first business day of the calendar year.  

The trustee holds the shares purchased by the ESOP in an unallocated suspense account, and shares are released from the suspense account on a pro-rata basis as the loan is repaid. The trustee allocates the shares released among participants on the basis of each participant’s proportional share of compensation relative to all participants.  Participants will vest in the first 20% of their account balances after two years of service and an additional 20% each year thereafter until full vesting occurs after six years. No vesting credit will be given for years of service prior to January 1, 2019. Participants also will become fully vested automatically upon normal retirement, death or disability, a change in control, or termination of the ESOP.  Generally, participants will receive distributions from the ESOP upon separation from service in accordance with the terms of the plan document.  The ESOP reallocates any unvested shares forfeited upon termination of employment among the remaining participants.

**Item 13. Certain Relationships and Related Transactions, and Director Independence**

**Board Independence**

The board of directors of Pioneer Bancorp has determined that each of the Company’s directors, except Mr. Amell, is “independent” as defined in, and for purposes of satisfying the listing standards of, the Nasdaq Stock Market.  Mr. Amell is not considered independent because he is an executive officer of Pioneer Bancorp and Pioneer Bank.  

In determining the independence of the Company’s directors, the Board of Directors considered relationships between Pioneer Bank and the directors that are not required to be reported under “— Transactions With Certain Related Persons,” below. TAGSolutions, an IT vendor for Pioneer Bank, is a wholly owned subsidiary of NextRidge Inc., a business partly owned by Director Mahoney. TAGSolutions received from Pioneer Bank payments totaling $274,000 during the year ended June 30, 2020. In addition, Mahoney Performance Institute, of which Director Mahoney is the owner and Chief Executive Officer, provided leadership training to the employees of Pioneer Bank and received $3,500 in fees during the year ended June 30, 2020. 

**Transactions With Certain Related Persons**

Section 402 of the Sarbanes-Oxley Act of 2002 generally prohibits an issuer from: (1) extending or maintaining credit; (2) arranging for the extension of credit; or (3) renewing an extension of credit in the form of a personal loan for an officer or director.  There are several exceptions to this general prohibition, one of which is applicable to Pioneer Bank.  The Sarbanes-Oxley Act does not apply to loans made by a depository institution that is insured by the Federal Deposit Insurance Corporation and is subject to the insider lending restrictions of the Federal Reserve Act.  All loans to Pioneer Bank’s directors and officers are made in conformity with the Federal Reserve Act and applicable regulations.  

All loans made by Pioneer Bank to executive officers, directors, immediate family members of executive officers and directors, or organizations with which executive officers and directors are affiliated, were made in the ordinary course of business, on substantially the same terms, including interest rates and collateral, as those prevailing at the time for comparable loans to persons not related to Pioneer Bank, and did not involve more than the normal risk of collectability or present other unfavorable features.  Pioneer Bank is in compliance with federal regulations with respect to its loans and extensions of credit to executive officers and directors. The aggregate amount of Pioneer Bank’s outstanding loans to executive officers and directors was approximatively $1.6 million at June 30, 2020.  As of June 30, 2020, these loans were performing according to their original repayment terms.  

Pursuant to the Policy and Procedures for Approval of Related Person Transactions, the Audit Committee periodically reviews, no less frequently than twice a year, a summary of transactions in excess of $25,000 with directors, executive officers, and their family members, for the purpose of determining whether the transactions are within the Company’s policies and should be ratified and approved.  Additionally, pursuant to the Code of Business Conduct and Ethics, all of executive officers and directors must disclose any personal or financial interest in any matter that comes before Pioneer Bancorp.

Tax Fees.  During the years ended June 30, 2020 and 2019, tax fees billed by Bonadio & Co., LLP were for tax preparation services and other tax-related consulting. 

**Policy on Audit Committee Pre-Approval of Audit and Non-Audit Services of Independent Registered Public Accounting Firm**

The Audit Committee has considered whether the provision of non-audit services, which relate primarily to tax services is compatible with maintaining the independence of Bonadio & Co., LLP.  The Audit Committee concluded that performing such services does not affect the independence of Bonadio & Co., LLP in performing its function as the Company’s independent registered public accounting firm.

The Audit Committee’s current policy is to pre-approve all audit and non-audit services provided by the independent registered public accounting firm, either by approving an engagement prior to the engagement or pursuant to a pre-approval policy with respect to particular services, subject to the de minimus exceptions for non-audit services described in Section 10A(i)(1)(B) of the Securities Exchange Act of 1934, as amended. These services may include audit services, audit-related services, tax services and other services.  The Audit Committee may delegate pre-approval authority to one or more members of the Audit Committee when expedition of services is necessary.  The independent registered public accounting firm and management are required to periodically report to the full Audit Committee regarding the extent of services provided by the independent registered public accounting firm in accordance with this pre-approval, and the fees for the services performed to date.  The Audit Committee pre-approved 100% of audit-related fees and tax fees billed and paid during the year ended June 30, 2020, as indicated in the table above.
