PROXY STATEMENT

FOR

2017 ANNUAL MEETING OF STOCKHOLDERS

GENERAL INFORMATION

We are providing this proxy statement to you in connection with the solicitation of proxies by the Board of Directors of PCSB Financial Corporation for use only at the 2017 annual meeting of stockholders and at any adjournment or postponement of the meeting. In this proxy statement, we may refer to PCSB Financial Corporation as “PCSB Financial,” the “Company,” “we,” “our” or “us.”

We are holding the 2017 annual meeting of stockholders at our executive offices/headquarters located at 2651 Strang Blvd., Suite 100, Yorktown Heights, New York on Wednesday, November 15, 2017 at 11:00 a.m., local time.

We intend to mail this proxy statement and the enclosed proxy card to stockholders of record beginning on or about October 12, 2017.

IMPORTANT NOTICE REGARDING THE AVAILABILITY OF PROXY MATERIALS

FOR THE STOCKHOLDERS’ MEETING TO BE HELD ON NOVEMBER 15, 2017

This proxy statement and the Company’s Annual Report on Form 10-K, as filed with the Securities and Exchange Commission, are available at http://astproxyportal.com/ast/21339.

INFORMATION ABOUT VOTING

Who Can Vote

You are entitled to vote your shares of Company common stock that you owned as of the close of business on September 29, 2017. As of the close of business on that date, 18,165,110 shares of Company common stock were outstanding. Each share of common stock has one vote.

The Company’s Articles of Incorporation provide that record holders of the Company’s common stock who beneficially own, either directly or indirectly, in excess of 10% of the Company’s outstanding shares are not entitled to any vote with respect to those shares held in excess of the 10% limit.

Ownership of Shares; Attending the Meeting

You may own shares of Company common stock in one or more of the following ways:

• Directly in your name as the stockholder of record;

• Indirectly through a broker, bank or other holder of record in “street name”;

• Indirectly through the PCSB Bank Employee Stock Ownership Plan (the “ESOP”); or

• Indirectly through the PCSB Bank 401(k) Savings Plan (the “401(k) Plan”).

2

If your shares are registered directly in your name, you are the holder of record of these shares and we are sending these proxy materials directly to you. As the holder of record, you have the right to give your proxy directly to us or to vote in person at the meeting.

If you hold your shares in street name, your broker, bank or other holder of record is sending these proxy materials to you. As the beneficial owner, you have the right to direct your broker, bank or other holder of record how to vote by filling out a voting instruction form that accompanies your proxy materials. Your broker, bank or other holder of record may allow you to provide voting instructions by telephone or by the Internet. See the instruction form provided by your broker, bank or other holder of record that accompanies this proxy statement. If you hold your shares in street name, you will need proof of ownership to be admitted to the meeting. Examples of proof of ownership are a recent brokerage statement or a letter from a bank or broker. If you want to vote your shares of Company common stock held in street name in person at the meeting, you must obtain a written proxy in your name from the broker, bank or other nominee who is the record holder of your shares.

If you own shares of Company common stock indirectly through the ESOP or the 401(k) Plan, see “ESOP and 401(k) Plan Participant Voting” for voting information.

Quorum and Voting

Quorum. We will have a quorum and will be able to conduct the business of the annual meeting if the holders of a majority of the outstanding shares of common stock entitled to vote are present at the meeting, either in person or by proxy.

Vote Required for Proposals. Stockholders will elect three directors to serve for a term of three years. In voting on the election of directors, you may vote in favor of the nominees, withhold votes as to all nominees, or withhold votes as to specific nominees. There is no cumulative voting for the election of directors. Directors must be elected by a plurality of the votes cast at the annual meeting, meaning that the nominees receiving the greatest number of votes will be elected up to the maximum number of directors to be elected at the annual meeting. The maximum number of directors to be elected at the annual meeting is three.

In voting on the ratification of the appointment of Crowe Horwath LLP to serve as the Company’s independent registered public accounting firm, you may vote in favor of the proposal, vote against the proposal or abstain from voting. To ratify the appointment, the affirmative vote of a majority of the votes cast at the annual meeting is required.

Counting of Votes. If you return valid proxy instructions or attend the meeting in person, we will count your shares to determine whether there is quorum, even if you abstain from voting. Broker non-votes will also be counted to determine the existence of a quorum.

In the election of directors, votes that are withheld and broker non-votes will have no effect on the outcome of the election.

In counting votes on the proposal to ratify the appointment of the independent registered public accounting firm, abstentions and broker non-votes will have no effect on the outcome of the vote on the proposal.

3

Effect of Not Casting Your Vote

If you hold your shares in street name, you must cast your vote if you want it to count in the election of directors. Current regulations prohibit your bank or broker from voting your uninstructed shares in the election of directors and on certain other matters on a discretionary basis. Therefore, if you hold your shares in street name and you do not instruct your bank or broker how to vote in the election of directors, no votes will be cast on these matters on your behalf. These are referred to as broker non-votes. Your bank or broker does, however, have discretion to vote any uninstructed shares on the ratification of the appointment of the independent registered public accounting firm.

Voting by Proxy

We are sending you this proxy statement to request that you allow your shares of Company common stock to be represented at the annual meeting by the persons named in the enclosed proxy card. All shares of Company common stock represented at the meeting by properly executed and dated proxies will be voted according to the instructions indicated on the proxy card. If you sign, date and return a proxy card without giving voting instructions, your shares will be voted as recommended by the Board of Directors. The Board of Directors unanimously recommends that you vote:

• “FOR” all of the nominees for director; and

• “FOR” the ratification of the appointment of Crowe Horwath LLP to serve as the independent registered public accounting firm.

We do not currently know of any other matters to be presented at the annual meeting. Execution of a proxy, however, confers discretionary authority on the designated proxy to vote the shares in accordance with their best judgment on such other business, if any, which may properly come before the annual meeting or any adjournments thereof.

Instead of voting by completing and mailing a proxy card, registered stockholders can vote their shares of Company common stock via the Internet or by telephone. The Internet and telephone voting procedures are designed to authenticate stockholders’ identities, allow stockholders to provide their voting instructions and confirm that their instructions have been recorded properly. Specific instructions for Internet and telephone voting appear on the enclosed proxy card and for the benefit plans on the voting instruction cards. The deadline for Internet and telephone voting is 11:59 p.m., Eastern Time, on November 14, 2017.

ESOP and 401(k) Plan Participant Voting

If you participate in the ESOP or invest in Company common stock through the 401(k) Plan, you will receive a voting instruction card for each plan that reflects all shares you may direct the trustees to vote on your behalf under the plan. You may submit your voting instruction cards, or convey your voting instructions via the Internet, by telephone or by mail. Specific instructions for Internet or telephone submission are set forth on the voting instruction cards. Under the terms of the ESOP, all allocated shares of Company common stock held by the ESOP are voted by the ESOP trustee, as directed by plan participants. The ESOP trustee generally votes all unallocated shares of Company common stock held by the ESOP and allocated shares for which no timely voting instructions are received in the same proportion as shares for which the ESOP trustee has received timely voting instructions, subject to the exercise of its fiduciary duties. If no shares have been allocated at the time of a stockholder vote, each participant will be deemed to have received one share for purposes of providing voting instructions. Under the terms of the 401(k) Plan a participant may direct the trustee how to vote the shares of Company common stock credited to the Participant under the plan. The Company will direct the 401(k) Plan trustee how to vote the shares of Company common stock for which timely voting instructions are not received. The deadline for returning voting instructions is November 8, 2017.

4

Revoking Your Proxy

Whether you vote or direct your vote by mail, telephone or via the Internet, if you are a registered stockholder or a participant in the ESOP and/or the 401(k) Plan, unless otherwise noted, you may later revoke your proxy by:

• sending a written statement to that effect to the Corporate Secretary;

• submitting a properly signed proxy card or voting instruction card with a later date;

• voting by telephone or by Internet at a later time (if initially able to vote in that manner) so long as the later vote or voting direction is received by the applicable date and time set forth above for registered stockholders and participants in the ESOP and/or the 401(k) Plan; or

• voting in person at the annual meeting (except for shares held in the ESOP and/or the 401(k) Plan).

If you hold your shares in “street name” through a bank, broker, trustee or nominee and you have instructed the bank, broker, trustee or nominee to vote your shares, you must follow the directions received from your bank, broker, trustee or nominee to change those instructions.

CORPORATE GOVERNANCE

Director Independence

The Board of Directors has determined that all of our directors, other than Messrs. Lusardi and Roberto, are “independent” as defined in, and for purposes of satisfying the listing standards of, the Nasdaq Stock Market. Mr. Roberto is not considered independent because he is an executive officer of the Company and PCSB Bank. Mr. Lusardi is not considered independent because of the aggregate amount of legal fees paid by the Company, PCSB Bank and by borrowers of PCSB Bank to his law firm during the fiscal year ended June 30, 2017 for legal services rendered to or on behalf of the Company and PCSB Bank.

In determining the independence of our directors, the Board of Directors considered the following relationships between the Company, PCSB Bank and our directors and officers, which is not required to be disclosed under “Other Information Relating to Directors and Executive Officers—Transactions with Related Persons” below. Mr. Thimm acts as a guarantor on a residential mortgage loan to an affiliated party. Mr. Weiss acts as a guarantor on a residential mortgage loan to a family member.

Board Leadership Structure and Board’s Role in Risk Oversight

The Board of Directors currently combines the offices of Chairman of the Board and Chief Executive Officer, but coupled with the designation of a lead independent director to strengthen the Company’s governance structure. The Board of Directors believes this structure provides an efficient and effective leadership model for the Company. Combining the offices of Chairman of the Board and Chief Executive Officer fosters clear accountability, effective decision-making, alignment on corporate strategy, and a clear and direct channel of communication between senior management and the full Board of Directors. Vice Chairman Richard F. Weiss serves as the lead independent director. The responsibilities of the lead independent director include leading all meetings of independent directors. To assure effective independent oversight, the Board of Directors has adopted a number of governance practices, including holding executive sessions of the independent directors at least twice a year or more often as needed.

Risk is inherent with every business, and how well a business manages risk can ultimately determine its success. The Company faces a number of risks, including credit risk, interest rate risk, liquidity risk, operational risk, strategic risk and reputation risk. Management is responsible for the daily management of risks the Company faces, while the Board of Directors, as a whole and through its committees, has responsibility for the oversight of risk management. In its risk oversight role, the Board of Directors has the responsibility to satisfy itself that the risk management processes designed and implemented by management are adequate and functioning as designed. To do this, the Chairman and Vice-Chairman of the Board meet regularly with management to discuss strategy and the risks facing the Company. Senior management attends Board meetings and is available to address any questions or concerns raised by the directors regarding risk management and any other matters. The Chairman and Vice-Chairman of the Board and the independent directors work together to provide strong, independent oversight of the Company’s management and affairs through its standing committees and, when necessary, special meetings of independent directors.

Corporate Governance Policy

The Board of Directors has adopted a corporate governance policy to govern certain activities, including: the duties and responsibilities of directors; the composition, responsibilities and operations of the Board; the establishment and operation of Board committees; succession planning; convening executive sessions of independent directors; the Board’s interaction with management and third parties; and the evaluation of the performance of the Board and of the Chairman, President and Chief Executive Officer.

Committees of the Board

The following table identifies the standing committees of the Company’s Board of Directors and their members as of June 30, 2017. All members of each committee are independent in accordance with the NASDAQ Stock Market listing requirements. Each committee operates under a written charter, which is approved by the Board of Directors and governs its composition, responsibilities and operation. Each committee reviews and reassesses the adequacy of its charter at least annually. Each committee charter is available at the Investor Relations section of PCSB Bank’s website (www.pcsb.com).

Audit Committee

The Audit Committee is responsible for providing oversight relating to our consolidated financial statements and financial reporting process, systems of internal accounting and financial controls, internal audit function, annual independent audit and the compliance and ethics programs established by management and the Board of Directors. The Audit Committee is also responsible for engaging the Company’s independent registered public accounting firm and monitoring its conduct and independence. The Board of Directors has designated Richard F. Weiss and Matthew G. McCrosson as “audit committee financial experts” as that term is defined by the rules and regulations of the Securities and Exchange Commission.

Compensation Committee

The Compensation Committee approves the compensation objectives for the Company and PCSB Bank, establishes the compensation for the Company’s and PCSB Bank’s executive management, and conducts the performance review of the Chairman, President and Chief Executive Officer. The Compensation Committee reviews all components of compensation, including salaries, cash incentive plans, long-term incentive plans and various employee benefit matters. Decisions by the Compensation Committee with respect to the compensation of executive officers are approved by the full Board of Directors.

Nominating/Corporate Governance Committee

The Nominating/Corporate Governance Committee assists the Board of Directors: (i) to identify individuals qualified to become Board members, consistent with criteria approved by the Board; (ii) to recommend the director nominees for the next annual meeting; (iii) to implement policies and practices relating to corporate governance, including implementation of and monitoring adherence to corporate governance guidelines; (iv) to lead the Board in its annual review of the Board’s performance; and (v) to recommend director nominees for each committee.

7

Minimum Qualifications for Director Nominees. The Nominating/Corporate Governance Committee has adopted a set of criteria that it considers when it selects individuals to be nominated for election to the Board of Directors. A candidate must meet the eligibility requirements set forth in the Company’s Bylaws, which include a residency requirement and a requirement that the candidate not have been subject to certain criminal or regulatory actions. A candidate also must meet any qualification requirements set forth in any Board or committee governing documents.

If a candidate is deemed eligible for election to the Board of Directors, the Nominating/Corporate Governance Committee will then evaluate the following criteria in selecting nominees:

• contributions to the range of talent, skill and expertise of the Board of Directors;

• financial, regulatory and business experience, knowledge of the banking and financial service industries, familiarity with the operations of public companies and ability to read and understand financial statements;

• familiarity with the Company’s market area and participation in and ties to local businesses and local civic, charitable and religious organizations;

• personal and professional integrity, honesty and reputation;

• the ability to represent the best interests of the stockholders of the Company and the best interests of the Company and Bank;

• the ability to devote sufficient time and energy to the performance of his or her duties; and

• independence, as is defined under applicable Securities and Exchange Commission and stock exchange listing criteria.

The Nominating/Corporate Governance Committee also will consider any other factors it deems relevant, including diversity, competition, size of the Board of Directors, and regulatory disclosure obligations.

With respect to nominating an existing director for re-election to the Board of Directors, the Nominating/Corporate Governance Committee will consider and review an existing director’s attendance and performance at meetings of committees on which he or she serves; length of service; the experience, skills and contributions that he or she brings to the Board of Directors; and independence.

Director Nomination Process. The process that the Nominating/Corporate Governance Committee follows to identify and evaluate individuals to be nominated for election to the Board of Directors is as follows:

For purposes of identifying director nominees, the Nominating/Corporate Governance Committee relies on personal contacts of its committee members and other members of the Board of Directors, as well as its knowledge of members of the communities served by PCSB Bank. The Nominating/Corporate Governance Committee will also consider director candidates recommended by stockholders according to the policy and procedures set forth below. The Nominating/Corporate Governance Committee has not used the services of an independent search firm to identify nominees.

8

In evaluating potential nominees, the Nominating/Corporate Governance Committee determines whether the candidate is eligible and qualified for service on the Board of Directors by evaluating the candidate under the criteria set forth above. If such individual fulfills these criteria, the Nominating/Corporate Governance Committee will conduct a check of the individual’s background and interview the candidate to further assess the qualities of the prospective nominee and the contributions he or she would make to the Board of Directors.

Considerations of Recommendations by Stockholders. The policy of the Nominating/Corporate Governance Committee is to consider director candidates recommended by stockholders who appear to be qualified to serve as a director. The Nominating/Corporate Governance Committee may choose not to consider an unsolicited recommendation if no vacancy exists on the Board of Directors and the Nominating/Corporate Governance Committee does not perceive a need to increase the size of the Board of Directors. In order to avoid the unnecessary use of the Nominating/Corporate Governance Committee’s resources, the Nominating/ Corporate Governance Committee will consider only those director candidates recommended in accordance with the procedures set forth below.

Procedures to be Followed by Stockholders. To submit a recommendation of a director candidate to the Nominating/Corporate Governance Committee, a stockholder should submit the following information in writing, addressed to the Corporate Secretary, at the main office of the Company:

1. A statement that the writer is a stockholder and is recommending a candidate for consideration by the Nominating/Corporate Governance Committee;

2. The name and address of the stockholder as he or she appears on the Company’s books, and number of shares of the Company’s common stock that are owned beneficially by such stockholder (if the stockholder is not a holder of record, appropriate evidence of the stockholder’s ownership will be required);

3. The name, address and contact information for the candidate, and the number of shares of the Company’s common stock that are owned by the candidate (if the candidate is not a holder of record, appropriate evidence of the stockholder’s ownership will be required);

4. A statement of the candidate’s business and educational experience;

5. Such other information regarding the candidate as would be required to be included in the proxy statement pursuant to SEC Regulation 14A;

6. A statement detailing any relationship between the candidate and any customer, supplier or competitor of the Company;

7. Detailed information about any relationship or understanding between the recommending stockholder and the candidate; and

8. A statement that the candidate is willing to be considered and willing to serve as a director if nominated and elected.

In order for a director candidate to be considered for nomination at the Company’s annual meeting of stockholders, the recommendation must be received by the Nominating/Corporate Governance Committee at least 60 days before the date the Company’s proxy statement was released to stockholders in connection with the previous year’s annual meeting, advanced by one year.

9

Board and Committee Meetings

During the fiscal year ended June 30, 2017, the Company’s Board of Directors held 7 meetings and PCSB Bank’s Board of the Directors held 14 meetings. No director attended fewer than 75% of the total meetings of the Company’s Board of Directors or of PCSB Bank’s Board of Directors and the respective committees on which such director served during fiscal 2017.

Director Attendance at Annual Meetings of Stockholders

This will be our first annual meeting since we completed our initial public offering this past April. The Board of Directors encourages each director to attend the annual meeting of stockholders.

Code of Ethics and Business Conduct

The Company has adopted codes of ethics and business conduct which apply to all of the Company’s and PCSB Bank’s directors, officers and employees. They are available on the Investor Relations portion of PCSB Bank’s website (www.pcsb.com).

REPORT OF THE AUDIT COMMITTEE

The Company’s management is responsible for the Company’s internal controls and financial reporting process. The Company’s independent registered public accounting firm is responsible for performing an independent audit of the Company’s consolidated financial statements and issuing an opinion on the conformity of those financial statements with generally accepted accounting principles in the United States of America (“GAAP”). The Audit Committee oversees the Company’s internal controls and financial reporting process on behalf of the Board of Directors.

In this context, the Audit Committee has met and held discussions with management and the independent registered public accounting firm. Management represented to the Audit Committee that the Company’s consolidated financial statements were prepared in accordance with GAAP and the Audit Committee has reviewed and discussed the consolidated financial statements with management and the independent registered public accounting firm. The Audit Committee discussed with the independent registered public accounting firm matters required to be discussed by Public Company Accounting Oversight Board (the “PCAOB”) Auditing Standard No. 1301, which include matters related to the conduct of the audit of the Company’s consolidated financial statements.

In addition, the Audit Committee has received the written disclosures and the letter from the independent registered public accounting firm, required by the applicable requirements of the PCAOB regarding the independent registered public accounting firm’s communications with the Audit Committee concerning independence, and has discussed with the independent registered public accounting firm the firm’s independence from the Company and its management. In concluding that the registered public accounting firm is independent, the Audit Committee considered, among other factors, whether the non-audit services provided by the firm were compatible with its independence.

The Audit Committee discussed with the Company’s independent registered public accounting firm the overall scope and plans for their audit. The Audit Committee meets with the independent registered public accounting firm, with and without management present, to discuss the results of their examination, their evaluation of the Company’s internal controls, and the overall quality of the Company’s financial reporting.

10

In performing all of these functions, the Audit Committee acts only in an oversight capacity. In its oversight role, the Audit Committee relies on the work and assurances of the Company’s management, which has the primary responsibility for financial statements and reports, and of the independent registered public accounting firm who, in its report, express an opinion on the conformity of the Company’s consolidated financial statements to GAAP. The Audit Committee’s oversight does not provide it with an independent basis to determine that management has maintained appropriate accounting and financial reporting principles or policies, or appropriate internal controls and procedures designed to assure compliance with accounting standards and applicable laws and regulations. Furthermore, the Audit Committee’s considerations and discussions with management and the independent registered public accounting firm do not assure that the Company’s consolidated financial statements are presented in accordance with GAAP, that the audit of the Company’s consolidated financial statements has been carried out in accordance with GAAP or that the Company’s independent registered public accounting firm is “independent.”

In reliance on the reviews and discussions referred to above, the Audit Committee has recommended to the Board of Directors, and the Board of Directors has approved, that the audited consolidated financial statements be included in the Company’s Annual Report on Form 10-K for the fiscal year ended June 30, 2017 for filing with the Securities and Exchange Commission. The Audit Committee also has approved, subject to stockholder ratification, the selection of the Company’s independent registered public accounting firm for the fiscal year ending June 30, 2018.

(1) Reflects the above market interest earned under the Trustee Fee Deferral Plan for the fiscal year ended June 30, 2017.

(2) Mr. Hill’s service as a director began in January 2017.

Director Fee Deferral Plan. PCSB Bank maintains a Director Fee Deferral Plan for non-employee directors. It is a non-qualified deferred compensation plan subject to the requirements of Section 409A of the Internal Revenue Code. A participant in the plan is eligible to defer a fixed percentage of the periodic fees the participant would be entitled to receive by entering into an election form and submitting it to PCSB Bank before initial participation, and thereafter, if desired, before the beginning of each plan year. As of the last day of each plan year, PCSB Bank credits each participant’s account with interest equal to the prime rate as reported in The Wall Street Journal on the first business day of the plan year, compounded annually, provided, that the crediting rate will not be less than 3% nor greater than 10%. A participant’s deferred fees and earnings are held by PCSB Bank until distributed to the participant. The participants’ account balances remain subject to the claims of PCSB Bank’s creditors in the event of PCSB Bank’s insolvency until distributed to the participants.

Each participant is entitled to elect, by filing a timely election form, whether to receive payment of the participant’s account balance on either of: (i) separation from service or (ii) a specified date. In addition, the participant may elect to receive payment in installments or in a lump sum distribution. If the participant fails to make an election, the participant’s account will be distributed in a lump sum distribution at the appropriate time. In addition, if a participant dies, becomes disabled or upon the occurrence of a change in control of PCSB Bank, the participant’s benefit will be distributed in a lump sum distribution.

Director Supplemental Life Insurance Plan. PCSB Bank has adopted a Director Supplemental Life Insurance Plan for non-employee directors. Eligible directors participating in the plan are Messrs. Kellogg, McCrosson, Cuddy, Lusardi, Thimm, Dwyer, and Weiss.

The Director Supplemental Insurance Plan provides for a death benefit to the beneficiaries if the director was in service with PCSB Bank at the time of his death. During a director’s period of coverage, the director is entitled to designate the beneficiary of his death benefit under the plan. The death benefit will be the lesser of (i) $100,000 or (ii) the net death benefit. For these purposes, the “net death benefit”

BUSINESS ITEMS TO BE VOTED ON BY STOCKHOLDERS

Item 1 — Election of Directors

The Board of Directors consists of ten members. The Board is divided into three classes, each with three-year staggered terms, with approximately one-third of the directors elected each year. All of the nominees for director and all of the directors continuing in office currently serve as directors of the Company and PCSB Bank.

Three directors will be elected at the annual meeting. On the recommendation of the Nominating/Corporate Governance Committee, the Board of Directors has nominated Richard F. Weiss, Karl A. Thimm and Michael T. Weber for election as directors. Each individual has agreed to serve and, if elected, will serve until their respective successors have been elected and qualified.

If any nominee is unable or declines to serve, the persons named in the proxy card as proxies will vote with respect to a substitute nominee designated by the current Board of Directors. At this time, the Board of Directors knows of no reason why any nominee would be unable to serve or would decline to serve, if elected.

The Board unanimously recommends that stockholders vote “FOR” all of the nominees.

Employment Agreements. Messrs. Roberto, Nogles and Goldrick (each an “executive” and, collectively, the “executives”) have each entered into employment agreements with the Company and PCSB Bank. The agreements have a term that ends on December 31, 2019, in the case of Mr. Roberto’s agreements, and December 31, 2018 in the case of Messrs. Nogles and Goldrick’s agreements. Each agreement will extend automatically for one additional year on January 1 of each year beginning January 1, 2018 unless either the employers or the applicable executive gives notice no later than 90 days before such anniversary date that an agreement will not be renewed.

20

Each agreement specifies the executive’s base salary, which currently is $560,000 for Mr. Roberto, $295,920 for Mr. Nogles and $255,505 for Mr. Goldrick. The base salary will be reviewed not less frequently than once every twelve months and may be increased in the board’s discretion. In addition to the base salary, the agreements provide that the executives shall be eligible to participate in short-term and long-term incentive compensation, determined and payable at the discretion of the Compensation Committee. The executives shall also be entitled to continue participation in any fringe benefit arrangements in which they were 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 executive’s duties. The agreement for Mr. Roberto provides that he will be entitled to a personal benefits allotment of $30,000 annually which will be used by him, in his sole discretion, towards a car allowance, country club membership, tax or financial advice or such other perquisites as he deems appropriate.

If the executive’s employment is terminated by PCSB Bank without cause, including a resignation for good reason (as defined in the agreement) during the term of the agreement, but excluding termination for cause or due to death, disability, retirement or following a change in control, the executive would be entitled to a payment equal to a multiple (i.e., three times for Mr. Roberto, two times for Mr. Nogles and one times for Mr. Goldrick) of the sum of: (i) his average base salary (or, in the case of Mr. Goldrick, his current base salary)plus (ii) his average annual incentive cash compensation awarded during the three (in the case of Mr. Roberto) and two (in the case of Messrs. Nogles and Goldrick) most recent fiscal years ending before the executive’s termination. The severance payment shall be paid to the executive within 30 days (or 60 days in certain circumstances) of the termination date, subject to the receipt of a signed release of claims from the executive within the time frame set forth in the agreement. In the case of Mr. Roberto, the payment shall also include a sum equal to three times his personal benefits allotment and a cash lump sum payment equal to the applicable co-payment percentage that PCSB Bank pays for his continuing life, medical and dental coverage, based on the costs of such coverage on the effective date of Mr. Roberto’s termination. Assuming Messrs. Nogles and Goldrick elect continued medical and dental coverage under COBRA, PCSB Bank and/or PCSB Financial will pay the applicable employer co-pay percentage for a period of 18 months, in the case of Mr. Nogles, and 12 months, in the case of Mr. Goldrick. Such coverage will be paid on a pre-tax basis, if providing such coverage did not result in excise taxes or penalties to PCSB Bank or PCSB Financial, otherwise such coverage would be provided on an after-tax basis. In addition, if Mr. Nogles elected continued COBRA coverage, PCSB Bank would also provide Mr. Nogles with a cash lump sum payment equal to the applicable employer co-pay percentage of such coverage for a period of an additional six months (based on the cost of such coverage at his termination date). PCSB Bank will also provide each executive with a cash lump sum payment equal to the cost of 24 months of life insurance premiums under the PCSB Bank-sponsored life insurance arrangements, in the case of Mr. Nogles, and 12 months, in the case of Mr. Goldrick (based on the cost of such coverage at the executive’s termination date). In addition, each executive would fully vest in any benefits under any nonqualified deferred compensation plans in which such executive is participating.

If the executive’s employment is terminated during the term of the agreement by PCSB 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 executive would be entitled to a payment equal a multiple (i.e., three times for Messrs. Roberto and Nogles and two times for Mr. Goldrick) of the sum of: (i) his current base salary (or his base salary in effect immediately before the change in control, if higher) plus (ii) his highest annual incentive cash compensation awarded during the three (in the case of Messrs. Roberto and Nogles) and two (in the case of Mr. Goldrick) most recent fiscal years ending before

21

the executive’s termination. The severance payment shall be paid to the executive within five business days of the termination date. In the case of Mr. Roberto, the payment shall also include a sum equal to three times his personal benefits allotment and a cash lump sum payment equal to the cost of providing continued life, medical and dental coverage for 36 months following termination, at no cost to the executive, based on the costs of such coverage on the effective date of Mr. Roberto’s date of termination. Assuming Messrs. Nogles and Goldrick elect continued medical and dental coverage under COBRA, the employers will pay the entire cost of such coverage for a period of 18 months. Such coverage will be paid on a pre-tax basis, if possible or if providing such pre-tax coverage does not result in excise taxes or penalties to PCSB Bank or PCSB Financial. Otherwise such coverage would be provided on an after-tax basis. In addition, if Messrs. Nogles and Goldrick elect continued COBRA coverage, the employers will also provide the executive with a cash lump sum payment equal to the cost of such coverage for a period of an additional 18 months, in the case of Mr. Nogles, and six months, in the case of Mr. Goldrick (based on the cost of such coverage at his termination date). The employers will also provide each executive with a cash lump sum payment equal to the premium cost for 36 months of life insurance coverage, in the case of Mr. Nogles, and 24 months, in the case of Mr. Goldrick (based on the cost of such coverage at the executive’s termination date). In addition, Messrs. Roberto and Nogles would fully vest in any benefits under any nonqualified deferred compensation plans in which such executive is participating.

For purposes of the executive’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 failure of the employers to continue the executive in the executive’s position or, in the case of Messrs. Roberto and Nogles, the issuance by the employers of a notice to the executive that the term of the employment agreement will not be extended; (ii) a material adverse change in the nature or scope of executive’s responsibilities, title, authorities, powers, functions or duties or the duties normally exercised by someone in his executive position, without his consent, (iii) an involuntary reduction in his base salary, except in connection with an across-the-board salary reduction affecting substantially all management employees and based on the employer’s financial performance, (iv) an involuntary relocation of executive’s principal place of employment by more than 35 miles driving distance from such office as determined at the date of the agreement, or (v) a material breach by the employers of the compensation provisions or any other provision of the agreement which continues for more than 10 days following notice given by the executive. If an event constituting “good reason” occurs, the executive is required to give the employers notice within 60 days and the employers will have 30 days to correct the good reason, however, the 30 day period may be waived by the employers.

If the payments to the executives under their employment agreements with the employers made in connection with a change in control would result in an excise tax under Sections 280G and 4999 of the Internal Revenue Code, the severance amounts payable to Messrs. Nogles and Goldrick would be reduced to avoid an excess parachute payment. The employment agreements with Mr. Roberto are silent with respect to any reduction.

If the executive is terminated due to disability, the employment agreement terminates. For these purposes, disability is defined as any medically determinable physical or mental impairment that can be expected to result in death or can be expected to last for a continuous period of not less than 12 months and that renders the executive unable to engage in any substantial gainful activity. If the executive dies while employed, the employers will continue to provide his base salary to his designated beneficiary for three months following his death.

Upon retirement of an executive according to any retirement policy established by the employers’ boards and consented to by the executive, the executive will be entitled to benefits under any retirement plans to which he is a party but shall not be entitled to any amount or benefits under the employment agreement.

22

The employment agreements require the executives not to compete with PCSB Bank for a period of one year following a termination of employment for which the executive receives severance payments as the result of an involuntary termination or resignation for good reason (other than a termination of employment following a change in control). The employment agreements further require that the executives not solicit business, customers or employees of PCSB Bank or PCSB Financial for a 12 month period following termination (other than a termination of employment following a change in control) and require the executives to maintain confidential information.

The employment agreements with PCSB Financial specify that there will be no obligation of payment or benefits paid under both the PCSB Bank and PCSB Financial employment agreements. To the extent that a payment is made or a benefit is received from PCSB Bank, the same payment or benefit will not be paid by or received from PCSB Financial.

Supplemental Executive Retirement Plan for Joseph D. Roberto. PCSB Bank has adopted a Supplemental Executive Retirement Plan for Mr. Roberto. Under the Supplemental Executive Retirement Plan, which is a nonqualified deferred compensation plan subject to Section 409A of the Internal Revenue Code, Mr. Roberto will be entitled to a normal retirement benefit if he separates from service after his normal retirement age of 68. The normal retirement benefit payable at age 68 is calculated as an annuity of $223,642 per year, payable in monthly installments for his lifetime with 15 years certain. If he separates from service before his normal retirement age (other than for cause or due to his death), his benefit will be reduced by 12.5% per year, for each year before his normal retirement age in which his separation occurs. If he works beyond his normal retirement age, his normal retirement benefit will be increased by multiplying the number of years beyond his normal retirement age that he works by 3% (i.e., retirement occurring five years beyond normal retirement age would result in a benefit equal to 115% of the normal retirement benefit). If PCSB Bank undergoes a change in control (as defined in the Supplemental Executive Retirement Plan), his benefit becomes fully vested. Upon Mr. Roberto’s separation from service, he will be entitled to a benefit equal to the normal retirement benefit. If he becomes disabled before attainment of his normal retirement age, his disability benefit would be equal to the benefit payable at his normal retirement age, payable in the form of a life annuity. If he is terminated for cause (as defined in the plan), he forfeits his right to any benefit under the Supplemental Executive Retirement Plan. Mr. Roberto’s right to a benefit under the Supplemental Executive Retirement Plan is conditioned on his agreement that for a period of one year following his termination of employment, he agrees not to solicit employees or customers of PCSB Bank to terminate their relationship with PCSB Bank, and further agrees not to otherwise compete with PCSB Bank within a 15 mile radius of the location in which PCSB Bank or its affiliates has business operations or has filed an application for regulatory approval to establish an office as of the date of his termination, provided that the requirement not to compete will not apply if his termination occurs following a change in control.

Contemporaneously with the adoption of the Supplemental Executive Retirement Plan, PCSB Bank purchased bank-owned life insurance and entered into a Supplemental Life Insurance Agreement (described below) with Mr. Roberto which would pay a death benefit to his beneficiary if he dies while employed at PCSB Bank. If he dies before retirement, his beneficiaries will receive a benefit under the life insurance agreement in lieu of any benefit under the Supplemental Executive Retirement Plan.

In connection with the adoption of the Supplemental Executive Retirement Plan, Mr. Roberto entered into a participation agreement with PCSB Bank confirming his participation in the plan. The participation agreement permitted him to elect to receive his benefits under the plan in a lump sum payment rather than in a life annuity with 15 years certain. He has elected to receive a lump sum payment under each payment alternative set forth above.

23

Supplemental Life Insurance Agreement for Joseph D. Roberto. In conjunction with the adoption of the Supplemental Executive Retirement Plan for Mr. Roberto, PCSB Bank also entered into a Supplemental Life Insurance Agreement with Mr. Roberto. In connection with the adoption of the Supplemental Life Insurance Agreement, PCSB Bank acquired one or more life insurance policies on Mr. Roberto’s life. PCSB Bank is the owner of the policy or policies and has entered into an endorsement form with Mr. Roberto to endorse a portion of the death benefits to Mr. Roberto or his beneficiary (such arrangements are referred to as “split dollar agreements”). If Mr. Roberto dies before the payment of his retirement benefit commences under the Supplemental Executive Retirement Plan, his beneficiary would be entitled to a cash lump sum payment from the Supplemental Life Insurance Agreement, in lieu of any benefit under the Supplemental Executive Retirement Plan, equal to the lesser of (i) $2,517,841 or (ii) the net death proceeds available under the Supplemental Life Insurance Agreement. For these purposes, the “net death proceeds” are defined as the total death proceeds in the policy or policies on Mr. Roberto’s life, minus the greater of (i) the cash surrender value of the policy or (ii) the aggregate premiums paid by PCSB Bank on the policy or policies. If Mr. Roberto dies after his retirement benefits have commenced under the Supplemental Executive Retirement Plan, his beneficiary will be entitled to receive a benefit under the Supplemental Life Insurance Agreement equal to the lesser of (i) the present value of the remaining retirement benefits that would have been paid to him under the Supplemental Executive Retirement Plan had he lived for 15 years after retirement, using a 5% discount rate (or such other reasonable rate as the board determines) and (ii) the net death proceeds. Since Mr. Roberto has elected to receive his retirement benefit under the Supplemental Executive Retirement Plan in a lump sum payment following his separation from service, it is expected that no further benefit would be payable to him under this plan following his retirement.

Supplemental Retirement Plan for Senior Executives. PCSB Bank has adopted a Supplemental Retirement Plan for Senior Executives, effective January 1, 2017. Messrs. Nogles and Goldrick are the only participants in the Supplemental Retirement Plan for Senior Executives. Each executive will be required to enter into a participation agreement evidencing his participation in the plan.

Under the Supplemental Retirement Plan for Senior Executives, which is a nonqualified deferred compensation plan subject to Section 409A of the Internal Revenue Code, the participating executive will be entitled to a supplemental benefit, calculated as a fixed annual payment for 15 years, if he separates from service after reaching his benefit age (which is age 65 in the case of both Messrs. Nogles and Goldrick). The “supplemental benefit” for Messrs. Nogles and Goldrick is equal to an annual payment of $75,000 and $50,000, respectively. The normal form of benefit will be a single lump sum payment equal of the present value of the supplemental benefit unless the executive makes a timely election to be paid in 15 annual installments. If the executive has a separation from service before reaching his benefit age (other than due to death, disability, the occurrence of a change in control or for cause), the executive will be entitled to the supplemental benefit multiplied by his applicable vested percentage. The supplemental benefit will vest in each executive in equal percentages over a seven year period.

If the executive dies before attaining his benefit age while employed at PCSB Bank, the executive’s beneficiary will be in entitled to the supplemental benefit and payment will commence on the first day of the second month following the executive’s death. If the executive dies following his separation from service and after becoming vested in any portion of the supplemental benefit but before commencement of benefit payments, the executive’s beneficiary will be entitled to the amount otherwise payable to the executive and payment will commence on the first day of the second month following the executive’s death.

If the executive becomes disabled before separation from service and before reaching the benefit age, the executive will receive the supplemental benefit as if the executive had reached his benefit age before disability. The payment will be made in a lump sum either within 30 days of the disability determination or at age 65, in accordance with the executive’s election set forth in his participation agreement.

24

If PCSB Bank has a change in control (as defined in the Supplemental Retirement Plan for Senior Executives) and the executive’s employment is involuntary terminated (including a good reason termination by the executive) following the change in control, the executive will be entitled to the supplemental benefit, calculated as if executive had attained his benefit age at the time of separation from service. If the executive’s employment is terminated within two years following the change in control, the executive’s benefit will be the present value of the supplemental benefit paid in a lump sum within 30 days following separation from service. If the executive’s employment terminates more than two years following the change in control (other than due to death or disability), the executive will be entitled to the supplemental benefit, payable in the manner set forth in the executive’s participation agreement for benefits payable on a “separation from service prior to benefit age” or “separation from service on or after benefit age”, as applicable. If a change in control occurs after the executive commences receiving the supplemental benefit paid in the form of installment payments and the executive has made an election in the participation agreement to receive a lump sum payment of the remaining amounts due following a change in control, the present value of the remaining payments will be determined and made payable no later than 30 days after the occurrence of the change in control.

If the executive is terminated for cause, he forfeits his rights to any benefit under the Supplemental Retirement Plan for Senior Executives. The benefits provided under the Supplemental Retirement Plan for Senior Executives are conditioned on the executive’s covenant that for a period of one year following the executive’s termination of employment (other than following a change in control), the executive will not compete with PCSB Bank in any city, town, or county in which the executive’s normal business office is located and PCSB Bank or the Company has an office or has filed an application for a regulatory approval to establish an office. In addition, the executive shall not hire or attempt to hire any employee of PCSB Bank or solicit any business from any customer of PCSB Bank or their subsidiaries.

Supplemental Life Insurance Plan. PCSB Bank maintains a Supplemental Life Insurance Plan for the benefit of certain executives, other than Mr. Roberto, who have been selected to participate in the plan. Messrs. Nogles and Goldrick are participants in the Supplemental Life Insurance Plan, which provides for a death benefit payment equal to the lesser of: (i) one and one-half times a participant’s highest rate of base salary, as in existence in the 2012 calendar year, or (ii) the executive’s net death proceeds if he dies while employed with PCSB Bank. For these purposes, the “net death proceeds” are defined as the total death proceeds in the officer’s policy minus the greater of the cash surrender value of the policy or the aggregate premiums paid by PCSB Bank on the policy. An officer’s participation in the Supplemental Life Insurance Plan will terminate: (i) if any regulatory agency requires PCSB Bank to sever its relationship with the executive; (ii) if PCSB Bank is subjected to regulatory restrictions limiting its ability to pay the compensation under the plan; (iii) in the event of insolvency, receivership or dissolution of PCSB Bank, (iv) upon termination of the executive’s employment, or (v) as otherwise may be determined by PCSB Bank’s Board of Directors in good faith.

Pension Plan. PCSB Bank maintains a Retirement Plan in RSI Retirement Trust, a qualified non-contributory defined benefit plan (the “pension plan”) for employees. PCSB Bank froze participation in the pension plan with respect to individuals hired after October 1, 2012 (i.e., a “soft freeze”). In connection with the soft freeze, employees of PCSB Bank before October 1, 2012, who completed one year of service, attained age 21, and were not in one of the excluded classifications were (and remain) eligible to accrue benefits under the pension plan. On February 15, 2017, PCSB Bank froze participation in the pension plan to all employees on May 1, 2017 (i.e., a “hard freeze”). After the hard freeze, no further benefits will accrue to the benefit of participants. Contributions to the Plan will continue to be

25

made, if necessary, in order to satisfy the actuarially determined minimum funding requirements according to the Employee Retirement Income Security Act of 1974, as amended (“ERISA”). A participant will become 100% vested in his or her accrued benefit under the plan after five years of service with PCSB Bank.

Under the terms of the frozen plan, upon attainment of normal retirement age (age 65) or upon termination after early retirement age (age 60), a participant who is not married and has accrued benefits in excess of $1,000 will receive a life annuity for the participant’s life, unless the participant elects another form of payment. If the participant is married and the present lump sum value of his accrued benefit exceeds $1,000, the normal form of payment will be a joint and survivor annuity, with a percentage of the participant’s benefit continuing to the participant’s spouse upon the participant’s death. If the participant’s vested account balance is $1,000 or less, the participant will receive a cash distribution as soon as practicable. A participant’s accrued benefit will become fully vested upon the participant’s death. If a participant dies while the participant is still employed by PCSB Bank or if the participant dies after he or she retires or terminates employment but before benefit payments start, the surviving spouse will be entitled to a life annuity based on the value of the participant’s vested accrued benefit.

The basic normal retirement benefit is calculated by multiplying the participant’s average of his highest three consecutive years of service by 2% for each year of credited service, up to a maximum of 30 years. A reduced benefit is payable upon early retirement at or after age 60. In the event of late retirement, the late retirement benefit will be the actuarial equivalent of the basic normal retirement benefit plus credit for accruals after attainment of normal retirement age.

401(k) Plan. PCSB Bank maintains a 401(k) Plan, which is a qualified, tax-exempt profit sharing plan with a salary deferral feature under Section 401(k) of the Code (the “401(k) Plan”). All employees who have attained age 21 and completed one year of eligibility service except for union employees, leased employees, and employees compensated on an hourly or commission basis are eligible to participate in the plan. Employees may make elective salary deferrals in an amount no less than 1% of compensation and up to the lesser of 25% of compensation (as defined by the 401(k) Plan) or $18,000 (as indexed). 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 $6,000 (as indexed). All employee elective salary deferrals and catch-up contributions are fully and immediately vested.

In addition, PCSB Bank will make an employer matching contribution equal to 75% of up to 6% of a participant’s compensation that the participant defers to the plan. In addition, employees who were hired on or after October 1, 2012, who were not eligible to participate in the pension plan due to its “soft freeze,” received an additional profit sharing contribution equal to 5% of their compensation. However, this additional profit sharing contribution was discontinued in 2017. Profit sharing contributions and employer matching contributions are subject to a six year vesting schedule. Participants are entitled to benefit payments upon termination of employment due to normal retirement at or after age 65, early retirement at or after age 60, disability or death. Benefits will be distributed in the form of lump sum, which is the normal form of distribution, or installment payments at the election of the participant.

Employee Stock Ownership Plan. PCSB Bank adopted an employee stock ownership plan for eligible employees, effective as of January 1, 2017, in connection with the Company’s initial public offering. Eligible employees who had attained age 21 and had completed one year of eligibility service on or before April 20, 2017, the closing date of the initial public offering, began to participate in the employee stock ownership plan, retroactively, as of January 1, 2017, the plan’s effective date. All employees, except for union employees, leased employees and employees compensated on an hourly basis or commission basis, are eligible to participate. Employees who did not satisfy the eligibility requirements on April 20, 2017 will become eligible to enter the plan on the first entry date commencing on or after both attainment of age 21 and completion of one year of service.

26

The employee stock ownership plan trustee purchased, on behalf of the employee stock ownership plan, 1,453,209 shares of the Company’s common stock issued in the initial offering with the proceeds of a loan from the Company equal to the aggregate purchase price of the common stock. The loan will be repaid principally through PCSB Bank’s contribution to the employee stock ownership plan and dividends payable on common stock held by the employee stock ownership plan over the anticipated 15-year term of the loan. Currently, the interest rate for the employee stock ownership plan loan is an adjustable-rate equal to the prime rate, as published in The Wall Street Journal, on April 20, 2017. The interest rate will adjust annually and will be the prime rate on the first business day of the calendar year, retroactive to January 1 of such year. The trustee will hold the shares purchased by the employee stock ownership plan in an unallocated suspense account and will release the shares from the suspense account as the employee stock ownership plan repays the loan. The trustee will allocate the shares released among participants on the basis of each participant’s proportional share of compensation relative to all participants. Participants will become 100% vested in their benefit after six years of credited service. Participants also will become fully vested upon normal retirement, death or disability, a change in control, or termination of the employee stock ownership plan. Generally, participants will receive distributions from the employee stock ownership plan after severance from employment.

OTHER INFORMATION RELATING TO DIRECTORS AND EXECUTIVE OFFICERS

Section 16(a) Beneficial Ownership Reporting Compliance

Section 16(a) of the Securities Exchange Act of 1934 requires the Company’s executive officers and directors, and persons who own more than 10% of any registered class of the Company’s equity securities, to file reports of ownership and changes in ownership with the Securities and Exchange Commission. These individuals are required by regulation to furnish the Company with copies of all Section 16(a) reports they file.

Based solely on its review of the copies of the reports it has received and written representations provided to it from the individuals required to file the reports, the Company believes that each of its executive officers and directors has complied with applicable reporting requirements for transactions in the Company’s common stock during the fiscal year ended June 30, 2017.

Transactions with Related Persons

Loans and Extensions of Credit. Federal law generally prohibits publicly traded companies from extending credit to their executive officers and directors, but it contains a specific exemption from the prohibition for extensions of credit made by federally insured financial institutions, such as PCSB Bank, to their executive officers and directors in compliance with federal banking regulations. However, it is the policy of PCSB Bank not to extend credit to its directors and executive officers and their related interests.

Other Transactions. Mr. Lusardi is a partner in the law firm of Daniels, Porco and Lusardi LLP, which received legal fees from the Company and PCSB Bank aggregating $143,726 for the fiscal year ended June 30, 2017.

CONFIDENTIAL ESOP VOTING INSTRUCTIONS

SOLICITED ON BEHALF OF THE TRUSTEE OF

PCSB BANK EMPLOYEE STOCK OWNERSHIP PLAN FOR

THE ANNUAL MEETING OF STOCKHOLDERS TO BE HELD ON NOVEMBER 15, 2017

Dear ESOP Participant:

On behalf of the Board of Directors of PCSB Financial Corporation (the “Company”), you are receiving the attached Vote Authorization Form to convey to Pentegra Trust Company (the “ESOP Trustee”) your voting instructions on the proposals to be presented at the Company’s Annual Meeting of Stockholders to be held at the Company’s headquarters at 2651 Strang Blvd., Suite 100, Yorktown Heights, New York on Wednesday, November 15, 2017 at 11:00 a.m., Eastern Standard Time (“EST”).

The PCSB Bank Employee Stock Ownership Plan (the “ESOP”) allows participants to direct the ESOP Trustee how to vote the common stock of the Company that has been allocated to the participants’ ESOP accounts. As of September 29, 2017, the record date for stockholders entitled to vote at the Annual Meeting, no shares have been allocated to any participant in the ESOP. If no shares have been allocated at the time of the Annual Meeting, each ESOP participant will be deemed to have one share of Company common stock allocated to his or her account for purposes of providing voting instructions to the ESOP Trustee. Therefore, as a participant in the ESOP, you will be deemed to have one share of Company common stock allocated to your account for purposes of issuing directions to the ESOP Trustee regarding the voting of such share at the Annual Meeting.

The ESOP Trustee has appointed American Stock Transfer & Trust Company, LLC (“AST”) as its agent to receive the ESOP Vote Authorization Forms and to tabulate the results. In order to direct the voting of the share deemed allocated to your account, you must either complete, sign and date the ESOP Authorization Form and return it in the accompanying postage-paid envelope to AST or you may provide your voting instructions via the Internet or by telephone, as described on the enclosed ESOP Vote Authorization Form.

Dear 401(k) Plan Participant:

On behalf of the Board of Directors of PCSB Financial Corporation (the “Company”), you are receiving the attached 401(k) Plan Vote Authorization Form to convey to Pentegra Trust Company (the “401(k) Plan Trustee”) your voting instructions with respect to shares of the Company’s common stock allocated to your account in the PCSB Bank 401(k) Savings Plan (the “401(k) Plan”) on the proposals to be presented at the Company’s Annual Meeting of Stockholders to be held on at the Company’s headquarters at 2651 Strang Blvd., Suite 100, Yorktown Heights, New York on Wednesday, November 15, 2017 at 11:00 a.m., Eastern Standard Time (“EST”).

The 401(k) Plan allows participants to direct the 401(k) Plan Trustee how to vote the common stock allocated to the participant’s 401(k) Plan account. As a participant in the 401(k) Plan with an investment in the PCSB Financial Stock Fund as of September 29, 2017, the record date for the Annual Meeting, you are entitled to instruct the 401(k) Plan Trustee how to vote the shares of Company common stock allocated to your account at the Annual Meeting by completing and returning the 401(k) Plan Vote Authorization Form.

The 401(k) Plan Trustee has appointed American Stock Transfer & Trust Company, LLC (“AST”) as its agent to receive the 401(k) Vote Authorization Forms and to tabulate the results. In order to direct the voting of the shares allocated to your account, you must either complete, sign and date the 401(k) Plan Vote Authorization Form and return it in the accompanying postage-paid envelope to AST or you may provide your voting instructions via the Internet or by telephone, as described on the enclosed 401(k) Vote Authorization Form. In any event your voting instructions must be received no later than 11:59 p.m., EST, on Wednesday, November 8, 2017.

The 401(k) Plan Trustee will vote the shares of Company common stock held in the 401(k) Plan in accordance with the timely received and completed voting instructions received from participants, so long as such vote is in accordance with the provisions of the Employee Retirement Income Security Act of 1974, as amended (“ERISA”).

IF YOU VOTE BY RETURNING THE 401(k) PLAN VOTE AUTHORIZATION FORM, IT MUST BE RECEIVED BY AST NO LATER THAN 11:59 P.M., EST, ON WEDNESDAY, NOVEMBER 8, 2017, SEVEN (7) DAYS BEFORE THE ANNUAL MEETING DATE. YOUR INDIVIDUAL VOTE WILL NOT BE REVEALED TO THE COMPANY.

2. Vote the shares as to which no timely instructions have been received, in the same proportion as shares for which the Trustee has received timely voting instructions, subject to its fiduciary duties under ERISA.
