Prospectus Supplement

PYRAMAX BANK, FSB 401(K) SAVINGS PLAN

Offering of Participation Interests in up to 1,295,457 Shares of

1895 Bancorp of Wisconsin, Inc. common stock

1895 Bancorp of Wisconsin, Inc., a new Maryland corporation that we refer to as “New 1895 Bancorp” throughout this prospectus supplement, is offering shares of common stock for sale at $10.00 per share in connection with the conversion of 1895 Bancorp of Wisconsin, Inc., a federal corporation that we refer to as “Old 1895 Bancorp” throughout this prospectus supplement, from the mutual holding company to the stock holding company form of organization. The shares being offered represent the ownership interest in Old 1895 Bancorp owned by 1895 Bancorp of Wisconsin, MHC. Old 1895 Bancorp’s common stock currently trades on the Nasdaq Capital Market under the trading symbol “BCOW.” We expect that New 1895 Bancorp’s common stock will be quoted on the Nasdaq Capital Market (NASDAQ) upon conclusion of the stock offering and we have applied to list the shares of New 1895 Bancorp common stock on the NASDAQ under the symbol “BCOW.”

The Bank has registered on behalf of the 401(k) Plan up to 1,295,457 participation interests so that the trustee of the 401(k) Plan could acquire up to 1,295,457 shares of New 1895 Bancorp common stock in the offering, at the purchase price of $10.00 per share and after the offering at the prevailing market price. Of the maximum that may be acquired by the 401(k) Plan, the shares available to purchase in the 401(k) Plan in the offering will be reduced by the number of shares of Old 1895 Bancorp currently held in the 401(k) Plan that will be exchanged for New 1895 Bancorp shares and the aggregate amount of participant loans outstanding. This prospectus supplement relates to the election of Plan participants to direct the trustee of the 401(k) Plan to invest up to 50% of their 401(k) Plan accounts in the 1895 Bancorp Stock Fund on the date of the stock offering.

RISK FACTORS

In addition to considering the material risks disclosed under “Risk Factors” beginning on page 19 of the attached prospectus, you should also consider the following:

If you elect to purchase New 1895 Bancorp common stock using your 401(k) Plan account balance and the stock offering is oversubscribed, you will bear the risk of price changes in the investment funds of the 401(k) Plan.

If you elect to purchase New 1895 Bancorp common stock using your existing 401(k) Plan account balance, the 401(k) Plan trustee will sell the designated dollar amount or percentage of your designated investment funds (other than the 1895 Bancorp Stock Fund) within your 401(k) Plan account based on your investment election and invest the proceeds in the new Stock Purchase Fund which has been established in connection with the stock offering. If the stock offering is oversubscribed (i.e., there are more orders for New 1895 Bancorp common stock than shares available for sale in the stock offering) and the 401(k) Plan trustee cannot use any or all of the funds you allocate to purchase New 1895 Bancorp common stock, the funds that cannot be invested in New 1895 Bancorp common stock, and any interest earned on such funds, will be reinvested in your existing investment funds of the 401(k) Plan (other than the existing 1895 Bancorp Stock Fund), according to your then existing investment election (i.e., in proportion to your investment direction for future contributions). During the period from when the 401(k) Plan trustee sells a percentage of each of your investment funds until reinvestment of some or all of those funds back into your investment funds as a result of an oversubscription, you will bear the risk of price changes in the investment funds. It is possible that during this period some or all of the investment funds may have increased in value more than the amount of any interest you may have earned on the reinvested funds before reinvestment. See “The Offering – Purchases in the Offering and Oversubscriptions” in this prospectus supplement.

THE OFFERING


Securities Offered		New 1895 Bancorp is offering participants in the PyraMax Bank, FSB 401(k) Savings Plan (the “401(k) Plan”) the opportunity to purchase stock of New 1895 Bancorp through the 401(k) Plan by purchasing “participation interests,” through the Stock Purchase Fund established under the 401(k) Plan in connection with the stock offering (or “offering”). The 401(k) Plan may acquire up to 1,295,457 shares of New 1895 Bancorp common stock in the stock offering at the purchase price of $10.00 per share and after the offering at the prevailing market price. Your investment in New 1895 Bancorp common stock in connection with the stock offering through the Stock Purchase Fund is subject to the purchase priorities contained in the Plan of Conversion and Reorganization of 1895 Bancorp of Wisconsin, Inc. (the “Plan of Conversion”).

		Information with regard to the 401(k) Plan is contained in this prospectus supplement and information with regard to the financial condition, results of operations and business of New 1895 Bancorp is contained in the accompanying prospectus. The address of the principal executive office of New 1895 Bancorp and the Bank is 7001 West Edgerton Avenue, Greenfield, WI 53220. The Bank’s telephone number is (414) 421-8200.

		Any questions about purchasing New 1895 Bancorp stock in the offering through the 401(k) Plan or about this prospectus supplement should be addressed to Monica Baker, Senior Vice President, Chief Brand Officer and Director, PyraMax Bank, FSB, 7001 West Edgerton Avenue, Greenfield, WI, 53220, telephone number (414) 235-5204.

S-1


Stock Purchase Fund		In connection with the conversion and stock offering, you may elect to designate up to 50% of your 401(k) Plan account balance to purchase common stock of New 1895 Bancorp issued in the stock offering at $10.00 per share by transferring a portion of your account balance to the new Stock Purchase Fund. For these purposes, your “account balance” will be determined by subtracting the amount of any participant loans you have outstanding. If the amount you elect to transfer to the Stock Purchase Fund plus the amount you have invested in the 1895 Bancorp of Wisconsin, Inc. Stock Fund (“1895 Bancorp Stock Fund”) exceeds 50% of your account balance (after subtracting participant loans), the excess will be returned to your other investments at the close of the offering. In making this determination, you should carefully consider the information set forth on page S-18 of this prospectus supplement under “Notice of Your Rights Concerning Employer Securities — The Importance of Diversifying Your Retirement Savings.” The trustee of the Stock Purchase Fund will purchase common stock of New 1895 Bancorp at $10.00 per share to be held as stock in accordance with your directions.

Purchase Priorities		401(k) Plan participants are eligible to direct a transfer of funds to the Stock Purchase Fund. However, such directions are subject to the purchase priorities and purchase limitations in the Plan of Conversion, which provides for a subscription and community offering, as described below.

		In the offering, the purchase priorities are as follows and apply in the case more shares are ordered than are available for sale (an “oversubscription”): Subscription offering: (1) First, to depositors of PyraMax Bank, FSB with $50 or more at the close of business on December 31, 2019. (2) Second, to PyraMax Bank, FSB’s and New 1895 Bancorp’s tax-qualified plans, including the employee stock ownership plan and the 401(k) Plan. (3) Third, to depositors of PyraMax Bank, FSB with $50 or more on deposit at the close of business on March 31, 2021. (4) Fourth, to members of PyraMax Bank, FSB (as defined in the Bank’s charter and bylaws) at the close of business on May 3, 2021 who do not qualify in one of the foregoing categories.

		If there are shares remaining after all of the orders in the subscription offering have been filled, shares will be offered in a community offering with a preference to natural persons residing in the Wisconsin Counties of Milwaukee, Waukesha and Ozaukee.

		If you fall into subscription offering categories (1), (3), or (4) above, you have subscription rights to purchase New 1895 Bancorp common stock in the subscription offering. You will separately receive offering materials in the mail, including a Stock Order Form. If you wish to purchase stock outside of the 401(k) Plan, you must complete and submit the Stock Order Form and payment, using the stock order reply envelope provided.

		Additionally, or instead of placing an order outside of the 401(k) Plan through a Stock Order Form, as a 401(k) Plan participant, you may place an order for common stock through the 401(k) Plan, in the manner described below under “How to Order Stock in the Offering.”

S-2


Purchases in the Offering and Oversubscriptions		The trustee of the 401(k) Plan will purchase New 1895 Bancorp common stock in the offering based on the dollar amount or percentage you designate in your on-line election. Once you make your election, the amount that you elect to transfer from your existing investment options for the purchase of New 1895 Bancorp common stock in connection with the stock offering will be removed from your existing investment options and transferred to the Stock Purchase Fund, which is an interest-bearing cash account in the 401(k) Plan, pending the formal closing of the stock offering, several weeks later. NOTE: any amount that you have invested in Old 1895 Bancorp common stock in the 1895 Bancorp Stock Fund will automatically convert to New 1895 Bancorp common stock pursuant to the exchange ratio that is determined in connection with the conversion. For further information on the exchange ratio see “How We Determined the Offering Range, the Exchange Ratio and the $10.00 Per Share Purchase Price” on page 7 of the accompanying prospectus.

		After the end of the stock offering period, we will determine whether all or any portion of your order may be filled (based on your purchase priority as described above and whether the stock offering is oversubscribed). The amount that can be used toward your order will be applied to the purchase of participation interests and will be denominated in shares of New 1895 Bancorp common stock in the 401(k) Plan.

		In the event the stock offering is oversubscribed, i.e. there are more orders for shares of New 1895 Bancorp common stock than shares available for sale in the stock offering, and the trustee is unable to use the full amount allocated by you to purchase shares of common stock in the stock offering, the amount that cannot be invested in shares of common stock, and any interest earned, will be reinvested in the other investment funds of the 401(k) Plan in accordance with your then existing investment election (in proportion to your investment direction for future contributions). If you do not have an existing election as to the investment of future contributions, then such amounts will be transferred to and invested in the applicable Blackrock Lifepath Index Fund, based on your retirement age assumption, pending your reinvestment in another fund of your choice.

		If you choose not to direct the investment of your account balances towards the purchase of any shares in the offering, your account balances will remain in the investment funds of the 401(k) Plan as previously directed by you. At the conclusion of the offering, once the eligible assets in the Stock Purchase Fund have been used to purchase New 1895 Bancorp common stock, the shares will be transferred to and held in the 1895 Bancorp Stock Fund. Your interests in the 1895 Bancorp Stock Fund will be referred to as participation interests and will be denominated in shares of 1895 Bancorp common stock.

Composition of 1895 Bancorp Stock Fund		The value of one participation interest will equal one share of common stock of New 1895 Bancorp, which will be initially valued at $10.00. Shares purchased in the 401(k) Plan in the offering as well as shares previously invested in the Old 1895 Bancorp common stock will be held in the 1895 Bancorp Stock Fund. The 1895 Bancorp Stock Fund is neither a mutual fund nor a diversified or managed investment option. Rather, it is merely a recordkeeping mechanism established in the 401(k) Plan to track the shares purchased by the participants in the 401(k) Plan. The 1895 Bancorp Stock Fund will invest 100% of the amounts allocated to the fund in common stock of New 1895 Bancorp. Each share of common stock will initially be valued at $10.00, the offering price of the common stock in the offering.

		Following the stock offering, as 401(k) Plan participants begin to trade their common stock in the 401(k) Plan in market transactions, the aggregate value of the 1895 Bancorp Stock Fund will increase or decrease depending on the total number of shares in the 1895 Bancorp Stock Fund at the end of the day multiplied by the closing price of 1895 Bancorp common stock on such date. The value of each participation interest will be the same as one share of New

S-3


		1895 Bancorp common stock. Your account in the 1895 Bancorp Stock Fund will be reported to you on your regular 401(k) Plan participant statements. You can also go on-line at any time to www.principal.com or call 1-800-547-7754 to review your account balances.

Value of the 401(k) Plan Assets		As of December 31, 2020, the market value of the assets of the 401(k) Plan attributable to active and former employees of the Bank was approximately $12,954,570. The 401(k) Plan administrator informed each participant of the value of his or her account balance under the 401(k) Plan as of December 31, 2020, however participants can also go on-line and look at their account balances at any time.

Election to Purchase Stock in the Offering		In connection with the stock offering, the 401(k) Plan will permit you to direct the trustee to transfer up to 50% of your account balance in the 401(k) Plan (after subtracting your participant loans) to the Stock Purchase Fund for the purchase of shares of common stock of 1895 Bancorp of Wisconsin, Inc. in the offering at $10.00 each. The trustee of the 401(k) Plan will subscribe for common stock of New 1895 Bancorp offered for sale in the offering, in accordance with each participant’s direction, provided, however, that if the amount transferred to the Stock Purchase Fund when aggregated with the amount you have invested in the Employer Stock Fund exceeds 50% of your account balance (subtracting participant loans), the excess will not be invested in common stock of New 1895 Bancorp and will be returned to your other investment funds after the offering closes. In making this determination, you should carefully consider the information set forth on page S-18 of this prospectus supplement under “Notice of Your Rights Concerning Employer Securities — The Importance of Diversifying Your Retirement Savings.”

How to Order Stock in the Offering		You can elect to transfer (in whole percentages or dollar amounts) up to 50% of your account balance (reduced by the amount you then have invested in the 1895 Bancorp Stock Fund and any participant loans you have outstanding) in the 401(k) Plan to the Stock Purchase Fund. Please note the following stipulations concerning this election:

		• You can direct up to 50% (in dollars or percentages) of your current account balance (after subtracting your participant loans) to the Stock Purchase Fund. • Your election is subject to a minimum purchase of 25 shares which equates to $250.00. • Your election, plus any order you placed outside the 401(k) Plan, is subject to a maximum purchase of 40,000 shares which equates to $400,000, or 50,000 shares which equates to $500,000 if you purchase in concert with an associate or group of persons acting in concert (as more fully described in the prospectus). • The election period closes at 3:00 p.m., Central Time, June 10, 2021.

		• Your election to purchase common stock in the offering through the 401(k) Plan will be accepted by Principal Financial Group, the recordkeeper of the 401(k) Plan. After your election is accepted, it will be rounded down to the closest dollar amount divisible by $10.00. The difference will remain in the Stock Purchase Fund until the formal close of the offering and the shares are acquired by the 401(k) Plan. This will occur several weeks after the election period ends. • At that time, the common stock purchased based on your election will be transferred to the 1895 Bancorp Stock Fund and any remaining funds from your account will be transferred out of the Stock Purchase Fund for investment in the other funds under the 401(k) Plan, based on your election currently on file for future contributions. If you do not have an election on file for future contributions, any remaining funds will be transferred to the

S-4


		applicable Blackrock Lifepath Index Fund, based on your retirement age assumption, to be reinvested by you in your discretion. • During the stock offering period, you will continue to have the ability to transfer amounts not invested in the Stock Purchase Fund among all the other investment funds on a daily basis. However, you will not be permitted to change the investment amounts that you designated to be transferred to the Stock Purchase Fund. • The amount you elect to transfer to the purchase of 1895 Bancorp common stock needs to be segregated and held until the offering closes. Therefore, this money is not available for distributions, loans or withdrawals until the offering is completed, which is several weeks after the closing of the subscription offering period.

DESCRIPTION OF THE 401(k) PLAN

Introduction

PyraMax Bank, FSB originally adopted the 401(k) Plan effective as of February 13, 1989. The 401(k) Plan was last restated, effective July 1, 2017. In connection with the conversion of PyraMax Bank, FSB from the mutual to stock form of organization as the wholly owned subsidiary of Old 1895 Bancorp, PyraMax Bank amended the 401(k) Plan to allow participants to purchase common stock of Old 1895 Bancorp with their 401(k) Plan accounts. The 401(k) Plan is a tax-qualified plan with a cash or deferred compensation feature established in accordance with the requirements under Section 401(a) and Section 401(k) of the Internal Revenue Code of 1986, as amended (the “Code”).

The Bank intends that the 401(k) Plan, in operation, will comply with the requirements under Section 401(a) and Section 401(k) of the Code. The Bank will adopt any amendments to the 401(k) Plan that may be necessary to ensure the continuing qualified status of the 401(k) Plan under the Code and applicable Treasury Regulations.

Employee Retirement Income Security Act of 1974 (“ERISA”). The 401(k) Plan is an “individual account plan” other than a “money purchase pension plan” within the meaning of ERISA. As such, the 401(k) Plan is subject to all the provisions of Title I (Protection of Employee Benefit Rights) and Title II (Amendments to the Code Relating to Retirement Plans) of ERISA, except the funding requirements contained in Part 3 of Title I of ERISA, which by their terms do not apply to an individual account plan (other than a money purchase plan). The 401(k) Plan is not subject to Title IV (Plan Termination Insurance) of ERISA. The funding requirements contained in Title IV of ERISA are not applicable to participants or beneficiaries under the 401(k) Plan.

Reference to Full Text of 401(k) Plan. The following portions of this prospectus supplement summarize certain provisions of the 401(k) Plan. They are not complete and are qualified in their entirety by the full text of the 401(k) Plan. Copies of the 401(k) Plan are available to all employees by filing a request with the 401(k) Plan Administrator c/o PyraMax Bank, FSB, Attn: Monica Baker, Senior Vice President, Chief Brand Officer.

As of December 31, 2020, there were approximately 118 active and former employees with account balances in the 401(k) Plan.

Contributions under the 401(k) Plan

Elective Deferrals. You are permitted to defer on a pre-tax basis up to 100% of your Compensation, subject to certain restrictions imposed by the Code, and to have that amount contributed to the 401(k) Plan on your behalf. Your pre-tax deferrals are subject to certain restrictions imposed by the Code, and for 2021, you may defer up to $19,500 and you may defer an additional $6,500 if you qualify for catch-up contributions as described in the next paragraph. The Compensation of each participant taken into account under the 401(k) Plan is limited by the Code, and for 2021 the limit is $290,000 (this limit may change on an annual basis). Canceling or changing your contribution percentage can be accomplished either over the telephone or over the internet at any time.

If, after receiving a notice from the Bank, you do not make an elective deferral contribution election, you will be deemed to have made an election to defer 6% of your Compensation. This percentage election will increase each year by 1% until your elective deferral is 10%. You can prevent this automatic deferral contribution election if you turn in the applicable form to prevent such contributions. Similarly, you can withdraw contributions made without your consent for up to a brief period of time after the automatic contributions are first removed from your Compensation.

Roth Elective Deferrals. You may elect to designate all or a portion of your deferrals as Roth elective deferrals. Roth elective deferrals do not reduce your total taxable income or your current taxes. Because you pay taxes on Roth elective deferrals when they are made, these contributions will not be taxed later when received as a benefit and distributed as a qualified distribution. A distribution will be a qualified distribution if (i) the distribution is made on or after you attain age 59¹/₂, on or after the date of your death, or as a result of you becoming disabled as defined by the Code; or (ii) the distribution is made after the end of the 5-taxable-year period beginning with the first taxable year in which you make a Roth elective deferral contribution to this plan.

Catch-up Contributions. If you have made the maximum amount of elective deferrals allowed by the 401(k) Plan or other legal limits and you have attained at least age 50 (or will reach age 50 prior to the end of the tax year, which is March 31), you are also eligible to make an additional catch-up contribution. In 2021, the maximum catch-up contribution is $6,500. You may authorize your employer to withhold a specified dollar amount of your compensation for this purpose.

Safe Harbor Matching Contributions. The Bank will make a safe harbor matching contribution to your account if you have satisfied the eligibility requirements and have made a “matched employee contribution during the plan year. A matched employee contribution is any elective deferral contribution or catch-up contribution that you may make. The safe harbor matching contribution is an amount equal to 100% of your matched employee contributions that are not in excess of six percent (6%) of your Compensation. The safe harbor matching contribution is subject to change from year to year, in the discretion of the Bank.

S-8

Profit Sharing Contributions. The Bank may, in its discretion, make profit sharing contributions to the accounts of eligible participants from time to time on a nondiscriminatory basis. The amount of any profit sharing contributions, if made, will be determined in the sole discretion of the Bank and will only be available to participants who have 1,000 hours of service during the plan year and are employed on the last day of the plan year.

Qualified Non-Elective Contributions. In addition to the contributions described above, the Bank may make additional qualified non-elective contributions for the benefit of participants determined at the discretion of the Bank.

Rollover Contributions. The 401(k) Plan may accept a rollover contribution from another tax-qualified plan or eligible individual retirement account made on behalf of an eligible employee, regardless of whether such employee has met the age and service requirements of the Plan. An eligible employee who has not met the age and service requirements of the 401(k) Plan shall be considered a participant only with respect to the amount of his or her rollover contributions, if any.

Limitations on Contributions

Contribution Limits. For the tax year beginning January 1, 2021, the amount of your elective deferrals may not exceed $19,500 per calendar year, or $26,000 if you are eligible to make catch-up contributions. Contributions in excess of this limit are known as excess deferrals. If you defer amounts in excess of this limitation, your gross income for federal income tax purposes will include the excess in the year of the deferral. In addition, unless the excess deferral is distributed before April 15 of the following year, it will be taxed again in the year distributed. Income on the excess deferral distributed by April 15 of the immediately succeeding year will be treated, for federal income tax purposes, as earned and received by you in the tax year in which the contribution is made.

The total amount of contributions that you make and any contribution your employer makes on your behalf to your account in one year is limited to the lesser of 100% of your compensation or $58,000 (for 2021), or if applicable, $64,500 (for 2021) including catch-up contributions.

Rollovers. You may make a rollover contribution of an eligible rollover distribution from any other qualified retirement plan or an individual retirement arrangement (IRA). These funds will be maintained in a separate rollover account in which you will have a nonforfeitable vested interest.

Benefits under the 401(k) Plan

Vesting. At all times, you have a fully vested, nonforfeitable interest in your elective deferrals, including Roth elective deferrals, catch-up contributions, if any, safe harbor matching contributions, qualified non-elective contributions and rollover contributions.

Your profit sharing contributions, if any, will vest in accordance with the following:


Vesting Schedule
Profit Sharing Contributions

Period of Service	Vested Percentage
Less than 2 years		0	%
2 years		20	%
3 years		40	%
4 years		60	%
5 years or more		100	%

Distribution at Termination of Employment. You will be entitled to receive a distribution of the vested amounts in your account when your employment terminates for any reason. Your benefit will be equal to the vested balance of your account. The 401(k) Plan will make involuntary cash-out distributions of vested account balances in accordance with the 401(k) Plan. If you are not a 5% or more owner of your employer, your required benefit commencement date is the April 1^st following the close of the year in which the later occurs: you attain age 72 or you terminate employment.

S-9

Distribution after Death of Participant. In the event of your death, the value of your entire account will be payable to your beneficiary in accordance with the 401(k) Plan.

Investment of Contributions and Account Balances

All amounts credited to your accounts under the 401(k) Plan are held in the 401(k) Plan trust (the “Trust”), which is administered by the trustee of the 401(k) Plan. Prior to the effective date of the Offering, you were provided the opportunity to direct the investments of your account into one of the investment options described below.

Administration of the 401(k) Plan

The Trustee and Custodian. The trustee of the 401(k) Plan is Principal Trust Company, however, in connection with the offering, PyraMax Bank, FSB, will appoint a “special trustee” consisting of certain officers of PyraMax Bank, FSB, to manage the purchases in the offering and the Stock Purchase Fund. After the offering has concluded, the special trustee will resign and Principal Trust Company will be the sole trustee of the 401(k) Plan.

Plan Administrator. Pursuant to the terms of the 401(k) Plan, the 401(k) Plan is administered by the 401(k) Plan administrator. The address of the 401(k) Plan administrator is PyraMax Bank, FSB, 7001 West Edgerton Avenue, Greenfield, WI 53220. The 401(k) Plan administrator is responsible for the administration of the 401(k) Plan, interpretation of the provisions of the 401(k) Plan, prescribing procedures for filing applications for benefits, preparation and distribution of information explaining the 401(k) Plan, maintenance of plan records, books of account and all other data necessary for the proper administration of the 401(k) Plan, preparation and filing of all returns and reports relating to the 401(k) Plan which are required to be filed with the U.S. Department of Labor and the Internal Revenue Service, and for all disclosures required to be made to participants, beneficiaries and others under Sections 104 and 105 of ERISA.

Reports to Plan Participants. The 401(k) Plan administrator will furnish a statement to you at least quarterly showing the balance in your account as of the end of that period, the amount of contributions allocated to your account for that period, and any adjustments to your account to reflect earnings or losses (if any). In addition, you can go on-line to principal.com or call 1-800-547-7754 at any time to review your account balances.

Amendment and Termination

It is the intention of the Bank to continue the 401(k) Plan indefinitely. Nevertheless, the Bank may terminate the 401(k) Plan at any time. If the 401(k) Plan is terminated in whole or in part, then regardless of other provisions in the 401(k) Plan, you will have a fully vested interest in your accounts. The Bank reserves the right to make any amendment or amendments to the 401(k) Plan which do not cause any part of the trust to be used for, or diverted to, any purpose other than the exclusive benefit of participants or their beneficiaries; provided, however, that the Bank may make any amendment it determines necessary or desirable, with or without retroactive effect, to comply with ERISA.

Merger, Consolidation or Transfer

In the event of the merger or consolidation of the 401(k) Plan with another plan, or the transfer of the trust assets to another plan, the 401(k) Plan requires that you receive a benefit immediately after the merger, consolidation or transfer which is equal to or greater than the benefit you would have been entitled to receive immediately before the merger, consolidation or transfer.

Federal Income Tax Consequences

The following is a brief summary of the material federal income tax aspects of the 401(k) Plan. You should not rely on this summary as a complete or definitive description of the material federal income tax consequences relating to the 401(k) Plan. Statutory provisions change, as do their interpretations, and their application may vary in individual circumstances. Finally, the consequences under applicable state and local income tax laws may not be the same as under the federal income tax laws. Please consult your tax advisor with respect to any distribution from the 401(k) Plan and transactions involving the 401(k) Plan.

As a “tax-qualified retirement plan,” the Code affords the 401(k) Plan special tax treatment, including:

(1) the sponsoring employer is allowed an immediate tax deduction for the amount contributed to the 401(k) Plan each year;

S-16

(2) participants pay no current income tax on elective deferrals, other than Roth deferrals, contributed by the employer on their behalf (Roth deferrals are taxed in the year deferred);

(3) earnings of the 401(k) Plan are tax-deferred, thereby permitting the tax-free accumulation of income and gains on investments; and

(4). Amounts distributed from the 401(k) Plan are generally taxed at ordinary income tax rates at the time of distribution.

Roth deferrals and earnings on Roth deferrals that are distributed in a qualifying distribution receive special tax treatment (see the discussion on Roth deferrals under the section on “Description of the 401(k) Plan—Contributions Under the 401(k) Plan”) In addition, special tax treatment is afforded to shares of common stock of New 1895 Bancorp distributed in a lump sum distribution after termination of employment. (See the discussion below under “Federal Income Tax Consequences—New 1895 Bancorp Common Stock Included in Lump-Sum Distribution.”)

The Bank will administer the 401(k) Plan to comply with the requirements of the Code as of the applicable effective date of any change in the law.

Lump-Sum Distribution. A distribution from the 401(k) Plan to a participant or the beneficiary of a participant will qualify as a lump-sum distribution if it is made within one taxable year, on account of the participant’s death, disability or separation from service, or after the participant attains age 59¹/₂, and consists of the balance credited to participants under the 401(k) Plan and all other profit sharing plans (and in some cases all other stock bonus plans), if any, maintained by the Bank. The portion of any lump-sum distribution required to be included in your taxable income for federal income tax purposes consists of the entire amount of the lump-sum distribution, less the amount of after-tax contributions, if any, you have made to this 401(k) Plan and any other profit sharing plans maintained by the Bank, which is included in the distribution.

New 1895 Bancorp Common Stock Included in Lump-Sum Distribution. If a lump-sum distribution includes 1895 Bancorp common stock, the distribution generally will be taxed in the manner described above, except that the total taxable amount may be reduced by the amount of any net unrealized appreciation with respect to 1895 Bancorp common stock, that is, the excess of the value of 1895 Bancorp common stock at the time of the distribution over its cost or other basis of the securities to the trust. The tax basis of 1895 Bancorp common stock, for purposes of computing gain or loss on its subsequent sale, equals the value of 1895 Bancorp common stock at the time of distribution, less the amount of net unrealized appreciation. Any gain on a subsequent sale or other taxable disposition of 1895 Bancorp common stock, to the extent of the amount of net unrealized appreciation at the time of distribution, will constitute long-term capital gain, regardless of the holding period of 1895 Bancorp common stock. Any gain on a subsequent sale or other taxable disposition of 1895 Bancorp common stock, in excess of the amount of net unrealized appreciation at the time of distribution, will be considered long-term capital gain. The recipient of a distribution may elect to include the amount of any net unrealized appreciation in the total taxable amount of the distribution, to the extent allowed by regulations to be issued by the Internal Revenue Service.

Distributions: Rollovers and Direct Transfers to Another Qualified Plan or to an IRA. You may roll over virtually all distributions from the 401(k) Plan to another qualified plan or to an individual retirement account (IRA) in accordance with the terms of the other plan or account.

Notice of Your Rights Concerning Employer Securities

Because you may in the future have investments in 1895 Bancorp Stock Fund under the 401(k) Plan, you should take the time to read the following information carefully.

Your Rights Concerning Employer Securities. The 401(k) Plan must allow you to elect to move any portion of your account that is invested in the 1895 Bancorp Stock Fund from that investment into other investment alternatives under the 401(k) Plan. You may contact the 401(k) Plan Administrator shown above for specific information regarding this right, including how to make this election. In deciding whether to exercise this right, you will want to give careful consideration to the information below that describes the importance of diversification. All of the investment options under the 401(k) Plan are available to you if you decide to diversify out of the 1895 Bancorp Stock Fund.

S-17

The Importance of Diversifying Your Retirement Savings. To help achieve long-term retirement security, you should give careful consideration to the benefits of a well-balanced and diversified investment portfolio. Spreading your assets among different types of investments can help you achieve a favorable rate of return, while minimizing your overall risk of losing money. This is because market or other economic conditions that cause one category of assets, or one particular security, to perform very well often cause another asset category, or another particular security, to perform poorly. If you invest more than 20% of your retirement savings in any one company or industry, your savings may not be properly diversified. Although diversification is not a guarantee against loss, it is an effective strategy to help you manage investment risk.

In deciding how to invest your retirement savings, you should take into account all of your assets, including any retirement savings outside of the 401(k) Plan. No single approach is right for everyone because, among other factors, individuals have different financial goals, different time horizons for meeting their goals, and different tolerance for risk. Therefore, you should carefully consider the rights described here and how these rights affect the amount of money that you invest in 1895 Bancorp common stock through the 401(k) Plan.

It is also important to periodically review your investment portfolio, your investment objectives, and the investment options under the 401(k) Plan to help ensure that your retirement savings will meet your retirement goals.

Additional ERISA Considerations

The 401(k) Plan is subject to certain provisions of ERISA, including special provisions relating to control over the 401(k) Plan’s assets by participants and beneficiaries. The 401(k) Plan’s feature that allows you to direct the investment of your account balances is intended to satisfy the requirements of Section 404(c) of ERISA relating to control over plan assets by a participant or beneficiary. The effect of this is two-fold. First, you will not be deemed a “fiduciary” because of your exercise of investment discretion. Second, no person who otherwise is a fiduciary, such as the Bank, the 401(k) Plan Administrator, or the 401(k) Plan’s trustee is liable under the fiduciary responsibility provision of ERISA for any loss which results from your exercise of control over the assets in your 401(k) Plan account.

Because you will be entitled to invest up to 50% of your account balance in the 401(k) Plan in New 1895 Bancorp common stock, the regulations under Section 404(c) of ERISA require that the 401(k) Plan establish procedures that ensure the confidentiality of your decision to purchase, hold, or sell employer securities, except to the extent that disclosure of such information is necessary to comply with federal or state laws not preempted by ERISA. These regulations also require that your exercise of voting and similar rights with respect to the common stock be conducted in a way that ensures the confidentiality of your exercise of these rights.

Securities and Exchange Commission Reporting and Short-Swing Profit Liability

Section 16 of the Securities Exchange Act of 1934, as amended, imposes reporting and liability requirements on (i) officers, (ii) directors, and (iii) persons beneficially owning more than 10% of public companies such as New 1895 Bancorp Section 16(a) of the Securities Exchange Act of 1934 requires the filing of reports of beneficial ownership. Within 10 days of becoming an officer, director or person beneficially owning more than 10% of the shares of New 1895 Bancorp the individual must fill out a Form 3 reporting initial beneficial ownership and file it with the Securities and Exchange Commission. Changes in beneficial ownership, such as purchases, sales and gifts generally must be reported periodically, either on a Form 4 within two business days after the change occurs, or annually on a Form 5 within 45 days after the close of New 1895 Bancorp’s fiscal year. Discretionary transactions in and beneficial ownership of the common stock through the New 1895 Bancorp Stock Fund of the 401(k) Plan by officers, directors and persons beneficially owning more than 10% of the common stock of New 1895 Bancorp generally must be reported to the Securities and Exchange Commission by such individuals.

S-18

In addition to the reporting requirements described above, Section 16(b) of the Securities Exchange Act of 1934, as amended, provides for the recovery by New 1895 Bancorp of profits realized by an officer, director or any person beneficially owning more than 10% of New 1895 Bancorp’s common stock resulting from non-exempt purchases and sales of New 1895 Bancorp common stock within any six-month period.

The Securities and Exchange Commission has adopted rules that provide exemptions from the profit recovery provisions of Section 16(b) for all transactions in employer securities within an employee benefit plan, provided certain requirements are met. These requirements generally involve restrictions upon the timing of elections to acquire or dispose of employer securities for the accounts of Section 16(b) persons.

Except for distributions of common stock due to death, disability, retirement, termination of employment or under a qualified domestic relations order, persons affected by Section 16(b) are required to hold shares of common stock distributed from the 401(k) Plan for six months following such distribution and are prohibited from directing additional purchases within the New 1895 Bancorp Stock Fund for six months after receiving such a distribution.
