******************************************************************************

Effective <award_date> (the “Date of Grant”), the Compensation Committee of the Board of Directors (the “Committee”) of BWX Technologies, Inc. (“BWXT”) awarded you a grant of performance-based Restricted Stock Units (“Performance RSUs”) under the Plan. The provisions of the Plan are incorporated herein by reference and capitalized terms used but not otherwise defined in this Agreement have the meanings given them in the Plan.

Any reference or definition contained in this Agreement shall, except as otherwise specified, be construed in accordance with the terms and conditions of the Plan and all determinations and interpretations made by the Committee with regard to any question arising hereunder or under the Plan shall be binding and conclusive on you and your legal representatives and beneficiaries. The term “BWXT” as used in this Agreement with reference to employment shall include subsidiaries of BWXT (including unconsolidated joint ventures). Whenever the words “you” or “your” are used in any provision of this Agreement under circumstances where the provision should logically be construed to apply to your beneficiary, estate, or personal representative, to whom any rights under this Agreement may be transferred by will or by the laws of descent and distribution, it shall be deemed to include such person.

Performance RSUs

1. Performance RSU Award. You have been awarded <shares_awarded> performance-based restricted stock units (the “Initial Performance RSUs”). These Performance RSUs represent a right to receive Shares, calculated as described below, provided (and to the extent that) the applicable performance measures and vesting requirements set forth in this Agreement have been satisfied. No Shares are awarded or issued to you on the Date of Xxxxx.

2. Vesting Requirements. Subject to Section 3 of this Agreement (the “Forfeiture of Performance RSUs” provision), Performance RSUs will become vested under one of the following circumstances, to the extent the Performance RSUs have not previously vested or become forfeited:

a percentage of the Initial Performance RSUs shall become vested on the third anniversary of the Date of Xxxxx (the “Third Anniversary Date”), provided you are still employed by BWXT (with the number in which you vest determined as described in Section 4 of this Agreement (the “Number of Performance RSUs” provision));

if your employment terminates on or after the first anniversary of the Date of Grant but prior to the Third Anniversary Date due to Retirement (as defined below) or an involuntary termination by BWXT without Cause, you will be eligible to vest in a number of Performance RSUs equal to the product of (a) the number of Performance RSUs that would have vested if you would have remained in the continuous employ of BWXT until the Third Anniversary Date or the occurrence of a Change in Control that would otherwise result in vesting (whichever occurs first) multiplied by (b) a fraction, the numerator of which is the number of calendar days you are employed by BWXT during the Performance Period, and the denominator of which is the total number of calendar days in the Performance Period;

100% of the Initial Performance RSUs shall become vested prior to the Third Anniversary Date on the earlier to occur of: (a) your death, or (b) your Disability; and

the Committee may provide for additional vesting under other circumstances, in its sole discretion.

In the event of a Change in Control that occurs prior to the vesting or forfeiture of the Performance RSUs, the Performance RSUs shall be treated as set forth in Article 16 of the Plan.

For purposes of this Agreement, “Retirement” means termination of your employment with BWXT (other than for Cause) after attaining (i) at least 60 years of age and (ii) at least [5 for key executives] [10] years of service with BWXT (with years of service calculated by reference from your “adjusted service date,” as determined by the Company).

3. Forfeiture of Performance RSUs. Except as otherwise provided in Section 2 above, Performance RSUs which are not or do not become vested upon your termination of employment for any reason shall, coincident therewith, be forfeited and be of no force and effect.

In the event of termination of your employment for Cause, as determined in the sole judgment of the Committee, all Performance RSUs and all rights or benefits awarded to you under this grant of Performance RSUs are forfeited, terminated and withdrawn immediately upon notice of such determination. The Committee shall have the right to suspend any and all rights or benefits awarded to you hereunder pending its investigation and final determination with regard to such matters. The forfeiture provisions of this paragraph are in addition to the provisions under the heading “Clawback Provisions” below.

4. Number of Performance RSUs. Except as otherwise provided in this Agreement and subject to adjustments permitted by the Plan, the number of Performance RSUs in which you will vest under this Agreement, if any, will be determined by multiplying (a) the sum of (i) 0.4 times the vested percentage applicable to Earnings Before Interest, Taxes, Depreciation, and Amortization

“EBITDA” plus (ii) 0.4 times the vested percentage applicable to Return on Invested Capital (“ROIC”), plus (iii) 0.2 times the vested percentage applicable to relative Total Shareholder Return (“TSR”) by (b) the number of Initial Performance RSUs. The maximum number of Performance RSUs in which you can vest is 200% of your Initial Performance RSUs and the minimum number of Performance RSUs in which you can vest is 0% of your Initial Performance RSUs.

The vested percentage applicable to EBITDA, ROIC and TSR will each be determined over the Performance Period as set forth on Schedule 1 attached hereto and incorporated by reference herein. For purposes of this Agreement, the “Performance Period” means the period beginning on January 1, 2023 and ending on December 31, 2025.

5. Settlement of Performance RSUs. You (or your beneficiary, if applicable) will receive one Share for each Performance RSU that vests under this Agreement. If you have made a permitted deferral election with respect to the Performance RSUs, then, subject to compliance with Section 409A of the Code (to the extent applicable), vested Performance RSUs shall be paid to you in accordance with such deferral election. If you have not made a permitted deferral election with respect to the Performance RSUs, vested Performance RSUs shall be paid to you as soon as administratively practicable after the Performance RSUs vest, but in no event later than the earlier of (a) March 15 following the end of the calendar year in which the Performance RSUs vest and (b) March 15, 2026 (and in all events within the short-term deferral period for purposes of Section 409A of the Code).

6. Dividend, Voting Rights and Other Rights. You shall have no rights of ownership in the Shares underlying the Performance RSUs and shall have no right to vote such Shares until the date on which the Shares are transferred to you pursuant hereto. From and after the Date of Grant and until the earlier of (a) the time when the Performance RSUs become vested and are paid in accordance with Section 5 hereof or (b) the time when your right to receive Shares in payment of the Performance RSUs is forfeited in accordance with Section 3 hereof, on the date that BWXT pays a cash dividend (if any) to holders of Shares generally, you shall be credited with cash per Performance RSU equal to the amount of such dividend. Any amounts credited pursuant to the immediately preceding sentence shall be subject to the same applicable terms and conditions (including vesting, payment and forfeitability) as apply to the Performance RSUs based on which the dividend equivalents were credited, and such amounts shall be paid in cash (without interest) at the same time as the Shares underlying the Performance RSUs to which they relate are delivered.

Taxes

7. Liability for Tax-Related Items. Regardless of any action BWXT or your employer (the “Employer”) takes with respect to any or all federal, state, local or foreign taxes or other tax-related amounts (“Tax-Related Items”), you acknowledge and agree that the ultimate liability for all Tax-Related Items legally due by you is and remains your responsibility and that BWXT and/or the Employer (i) make no representations nor undertakings regarding the treatment of any Tax-Related Items in connection with any aspect of this grant of Performance RSUs, including the grant and vesting of Performance RSUs, subsequent delivery of Shares or the subsequent sale of any Shares acquired pursuant to such Performance RSUs and receipt of any dividend equivalent payments (if any) and (ii) do not commit to structure the terms or any aspect of this grant of Performance RSUs to reduce or eliminate your liability for Tax-Related Items. To the extent that BWXT or the Employer is required to withhold Tax-Related Items in connection with any payment made to or benefit realized by you or another person with respect to the Performance RSUs, you agree that, unless otherwise determined by the Committee, BWXT or the Employer will withhold Shares having a value equal to (A) the minimum statutory withholding amount permissible or (B) if approved by the Committee, a greater amount based on your election. In no event will the market value of the Shares to be withheld and/or delivered pursuant to this Section 7 to satisfy applicable Tax-Related Items exceed your estimated tax obligations attributable to the applicable transaction. To the extent that the amounts available to BWXT or the Employer for such withholding are insufficient, it shall be a condition to the receipt of such payment or the realization of such benefit that you or such other person make arrangements satisfactory to BWXT or the Employer, as applicable, for payment of the balance of such Tax-Related Items required to be withheld. The Shares withheld as described above shall be credited against any such withholding requirement at the fair market value of such Shares on the date the applicable benefit is to be included in your income.

Transferability

8. Non-Transferability. Performance RSUs granted hereunder are non-transferable other than by will or by the laws of descent and distribution.

Clawback Provisions

9. Recovery of Performance RSUs. In the event that BWXT is required to prepare an accounting restatement due to the material noncompliance of BWXT with any financial reporting requirement under the U.S. federal securities laws as a result of misconduct (a “Restatement”) and the Board reasonably determines that you knowingly engaged in the misconduct, BWXT will have the right to recover the Performance RSUs granted during the three-year period preceding the date on which the Board or BWXT, as applicable, determines it is required to prepare the Restatement (the “Three-Year Period”), or vested in whole or in part during the Three-Year Period, or the proceeds related to the Performance RSUs in the Three-Year Period, to the extent of any excess of what would have been granted to or would have vested for you under the Restatement.

10. Recovery Process. In the event a Restatement is required, the Board, based upon a recommendation by the Committee, will (a) review the Performance RSUs either granted or vested in whole or in part during the Three-Year Period and (b) in accordance with the provisions of this Agreement and the Plan, will take reasonable action to seek recovery of the amount of such Performance RSUs in excess of what would have been granted to or would have vested for you under the Restatement (but in no event more than the total amount of such Performance RSUs), as such excess amount is reasonably determined by the Board in its sole discretion, in compliance with

Section 409A of the Code. There shall be no duplication of recovery under Sections 9 and 10 of this Agreement and any of 15 U.S.C. Section 7243 (Section 304 of The Xxxxxxxx-Xxxxx Act of 2002) and Section 10D of the Exchange Act. Notwithstanding anything in this Agreement to the contrary, you acknowledge and agree that this Agreement and the award described herein (and any settlement thereof) are subject to the terms and conditions of the Company’s clawback policy (if any) as may be in effect from time to time, or otherwise adopted after the Date of Grant for any reason, including specifically to implement Section 10D of the Exchange Act, and any applicable rules or regulations promulgated thereunder (including applicable rules and regulations of any national securities exchange on which the Shares may be traded) (the “Compensation Recovery Policy”), and that Sections 9 and 10 of this Agreement shall be deemed superseded by and subject to the terms and conditions of the Compensation Recovery Policy from and after the effective date thereof.

Other Information

11. No Guarantee of Continued Service. Neither the action of BWXT in establishing the Plan, nor any action taken by it, by the Committee or by your employer, nor any provision of the Plan or this Agreement shall be construed as conferring upon you the right to be retained in the employment of BWXT or any of its subsidiaries or affiliates.

12. Adjustments. The Performance RSUs evidenced by this Agreement are subject to adjustment as provided in Sections 4.3 and 17.2 of the Plan.

13. Compliance with Section 409A of the Code. To the extent applicable, it is intended that this Agreement and the Plan comply with the provisions of Section 409A of the Code. This Agreement and the Plan shall be administered in a manner consistent with this intent, and any provision that would cause this Agreement or the Plan to fail to satisfy Section 409A of the Code shall have no force or effect until amended to comply with Section 409A of the Code (which amendment may be retroactive to the extent permitted by Section 409A of the Code and may be made by BWXT without your consent). Any reference in this Agreement to Section 409A of the Code will also include any proposed, temporary or final regulations, or any other guidance, promulgated with respect to such Section by the U.S. Department of the Treasury or the Internal Revenue Service.

14. Electronic Delivery. BWXT may, in its sole discretion, deliver any documents related to the Performance RSUs and your participation in the Plan, or future awards that may be granted under the Plan, by electronic means or request your consent to participate in the Plan by electronic means. You hereby consent to receive such documents by electronic delivery and, if requested, agree to participate in the Plan through an on-line or electronic system established and maintained by BWXT or another third party designated by BWXT.

15. Severability. In the event that one or more of the provisions of this Agreement shall be invalidated for any reason by a court of competent jurisdiction, any provision so invalidated shall be deemed to be separable from the other provisions hereof, and the remaining provisions hereof shall continue to be valid and fully enforceable.

16. Successors and Assigns. Without limiting Section 8 hereof, the provisions of this Agreement shall inure to the benefit of, and be binding upon, your successors, administrators, heirs, legal representatives and assigns, and the successors and assigns of the Company.

17. Acknowledgement. You acknowledge that you (a) have received a copy of the Plan, (b) have had an opportunity to review the terms of this Agreement and the Plan, (c) understand the terms and conditions of this Agreement and the Plan and (d) agree to such terms and conditions.

18. Country-Specific Special Terms and Conditions. Notwithstanding any provisions in this Agreement, the Performance RSUs shall also be subject to the special terms and conditions set forth in Appendix A to this Agreement for your country of residence. Moreover, if you relocate to one of the countries included on Appendix A, the special terms and conditions for such country will apply

to you, to the extent BWXT determines that the application of such terms and conditions are necessary or advisable in order to comply with local law or facilitate the administration of the Plan. Appendix A constitutes part of this Agreement.

19. Notice to Governmental Authority. Notwithstanding anything in this Agreement to the contrary, nothing in this Agreement prevents you from providing, without prior notice to BWXT, information to governmental authorities regarding possible legal violations or otherwise testifying or participating in any investigation or proceeding by any governmental authorities regarding possible legal violations, and for purpose of clarity you are not prohibited from providing information voluntarily to the Securities and Exchange Commission pursuant to Section 21F of the 1934 Act.

Schedule 1

Calculating EBITDA, ROIC and TSR

Except as otherwise described below, the component values used to calculate EBITDA, ROIC and TSR will be determined in accordance with U.S. generally accepted accounting principles excluding (1) expenses associated with the acquisition or disposition of any asset, (2) expenses associated with company restructuring activity, (3) any pension accounting mark-to-market losses, (4) acquisition related amortization resulting from an acquisition that occurs during the Performance Period, (5) losses from divestitures, (6) impairments of tangible and intangible assets, (7) losses in respect of legal proceedings and dispute resolutions, (8) losses from tax valuation allowances, (9) fluctuations in foreign currency exchange rates impacting translation of foreign earnings into USD, and (10) losses in respect of an Act of God/Force Majeure matter. The performance goals or the component values will also be adjusted to reflect the negative effects from applicable changes in accounting standards / policies or tax regulations after the Date of Grant. No adjustment herein shall limit any discretion provided by the Plan to increase or reduce the amount of a Participant’s Final Award as computed hereunder.

Earnings Before Interest Taxes Depreciation and Amortization (EBITDA)

The vested percentage applicable to EBITDA will be determined based on BWXT’s cumulative EBITDA (as calculated below) (“Cumulative EBITDA”) for the Performance Period in accordance with the following schedule:

Cumulative EBITDA EBITDA Vested Percentage

$ x.xx 50%

$ x.xx 100%

$ x.xx 200%

Vested percentages between the amounts shown will be calculated by linear interpolation. The vested percentage applicable to EBITDA will be 0% if the Cumulative EBITDA for the Performance Period is below $x.xx. In no event will the vested percentage applicable to EBITDA be greater than 200%.

EBITDA will be calculated for each calendar year during the Performance Period and Cumulative EBITDA for the Performance Period will equal the sum of the three applicable annual EBITDA calculations.

For purposes of this Agreement, the term “EBITDA” means BWXT’s operating income for the applicable period plus depreciation and amortization expense for the applicable period.

Return on Invested Capital (ROIC)

The vested percentage applicable to ROIC will be determined based on BWXT’s average annual ROIC (as calculated below) (“Average ROIC”) for the Performance Period in accordance with the following schedule:

Average ROIC ROIC Vested Percentage

xx.x% 50%

xx.x% 100%

xx.x% 200%

Vested percentages between the amounts shown will be calculated by linear interpolation. The vested percentage applicable to ROIC will be 0% if the Average ROIC for the Performance Period is below xx.x%. In no event will the vested percentage applicable to ROIC be greater than 200%.

ROIC will be calculated quarterly and the ROIC for any calendar year during the Performance Period will equal the sum of the four applicable quarterly ROIC calculations. Average ROIC will equal the sum of the three annual ROIC calculations during the Performance Period divided by three.

For purposes of this Agreement, the term “ROIC” is a ratio measure of BWXT’s net income in relation to BWXT’s invested capital. For purposes of determining ROIC, net income is pre-tax income less tax expense calculated in accordance with U.S. generally accepted accounting principles. Invested capital is BWXT’s total assets less current liabilities. Current liabilities include any liabilities that are due within one calendar year and will be defined based on BWXT’s consolidated balance sheet applicable to the applicable period.

Total Shareholder Return (TSR)

The vested percentage applicable to TSR will be determined based on BWXT’s TSR (as defined below) over the Performance Measurement Period relative to the TSR of the companies included in the S&P Aerospace & Defense Select Industry Index as of the first business day of the Performance Measurement Period (as defined below) and set forth in Schedule 2 attached herewith (the “TSR Companies”) during the same period in accordance with the following schedule:

TSR Ranking Relative to TSR Companies TSR Vested Percentage

<25th percentile 0%

25th percentile 50%

50th percentile 100%

>75th percentile 200%

Vested percentages between the amounts shown will be calculated by linear interpolation. The vested percentage applicable to TSR will be 0% if BWXT’s TSR ranks lower than the 25th percentile relative to the TSR Companies. In no event will the vested percentage applicable to TSR be greater than 200%. If BWXT’s TSR during the Performance Measurement Period is negative, the vested percentage applicable to TSR shall not exceed 100%.

For purposes of this Agreement, the term TSR means [(a) – (b) + (c)]/b, where (a) is the Stock Price (as defined below) on the last business day of the Performance Measurement Period, (b) is the Stock Price on the first business day of the Performance Measurement Period and (c) is dividends paid and reinvested during the Performance Measurement Period. The term “Stock Price” means the average daily closing price of a

share of common stock of the applicable company during the preceding 30 calendar days. The Stock Price shall be adjusted to reflect a stock split, spin-off or other extraordinary corporate event occurring during the Performance Measurement Period.

The Committee, in its discretion, may adjust the composition of the TSR Companies due to extraordinary corporate events involving these companies, including but not limited to merger, acquisition, bankruptcy, dissolution or divestiture.

Schedule 2

7.Liability for Tax-Related Items. Section 6 of the Agreement (the “Liability for Tax-Related Items” provision) is deleted in its entirety and replaced with the following:

“Liability for Tax-Related Items. Regardless of any action BWXT or your employer (the “Employer”) takes with respect to any or all federal, state, provincial, local, foreign, social insurance, payroll or other taxes (“Tax-Related Items”), you acknowledge and agree that the ultimate liability for all Tax-Related Items legally due by you is and remains your responsibility and that BWXT and/or the Employer (i) make no representations nor undertakings regarding the treatment of any Tax-Related Items in connection with any aspect of this grant of Performance RSUs, including the grant and vesting of Performance RSUs, subsequent delivery of Shares or the subsequent sale of any Shares acquired pursuant to such Performance RSUs and any dividend equivalent (if any) and (ii) do not commit to structure the terms or any aspect of this grant of Performance RSUs to reduce or eliminate your liability for Tax-Related Items. To the extent that BWXT or the Employer is required to withhold Tax-Related Items in connection with any payment made to or benefit realized by you or another person with respect to the Performance RSUs, you agree that, unless otherwise determined by the Committee, BWXT or the Employer will withhold Shares having a value equal to (A) the minimum statutory withholding amount permissible or (B) if approved by the Committee, a greater amount based on your election. In no event will the market value of the Shares to be withheld and/or delivered pursuant to this Section 7 to satisfy applicable Tax-Related Items exceed your estimated tax obligations attributable to the applicable transaction. Furthermore, you may withdraw such agreement to withhold Shares at any time, provided that you make advance arrangements satisfactory to BWXT and the Employer to satisfy the withholding of Tax-Related Items as and when they become due. To the extent that the amounts available to BWXT or the Employer for such withholding are insufficient, it shall be a condition to the receipt of such payment or the realization of such benefit that you or such other person make arrangements satisfactory to BWXT or the Employer, as applicable, for payment of the balance of such Tax-Related Items required to be withheld. Any Shares withheld as described above shall be credited against any such withholding requirement at the fair market value of such Shares on the date the applicable benefit is to be included in your income.

If the obligation for Tax-Related Items is satisfied by withholding a number of Shares as described herein, you understand that you will be deemed to have been issued the full number of Shares subject to the settled Performance RSUs, notwithstanding that a number of Shares are held back solely for the purpose of paying the Tax-Related Items due as a result of the settlement of the Performance RSUs. Notwithstanding anything herein to the contrary, if the Federal Insurance Contributions Act tax (“FICA Tax”) imposed under Sections 3101, 3121(a) and 3121(v)(2) of the Code becomes due with respect to any of the Performance RSUs prior to the payment of such Performance RSUs, BWXT or Employer will withhold from your cash compensation an amount sufficient to pay the FICA Tax with respect to such Performance RSUs.

8.Language Consent. The following provision will apply to residents of Quebec:

The parties acknowledge that it is their express wish that this Agreement, as well as all documents, notices, and legal proceedings entered into, given or instituted pursuant hereto or relating directly or indirectly hereto, be drawn up in English.

Les parties reconnaissent avoir exigé la rédaction en anglais de cette convention, ainsi que de tous documents, avis et procédures judiciaires, exécutés, donnés ou intentés en vertu de, ou liés directement ou indirectement à la présente convention.

9.Dividend Equivalents Settled in Shares Only. Notwithstanding anything to the contrary in the Plan and/or this Agreement, any dividend equivalents credited shall be in the form of additional Performance RSUs that are subject to the same terms and conditions, including vesting and time of settlement, as the Performance RSUs to which they relate and shall only be settled in Shares.

10.Performance RSUs Settled in Shares Only. Notwithstanding anything to the contrary in the Plan and/or this Agreement, the Company shall not have the right unilaterally to cause you to surrender all or a portion of your Performance RSUs for cash in lieu of Shares (including with respect to cash amounts required to satisfy Tax-Related Items). However, from time to time, the Committee may provide you with the right to elect (which right may be time-limited and/or tied to the occurrence of contingent events, at the Committee’s sole discretion) to surrender such Performance RSUs for a cash compensation payment. Any Performance RSUs that you have not elected to be surrendered for cash compensation shall only be settled in Shares or, if so determined by the Committee and communicated to you in advance, forfeited.

11.Form of Payment. Notwithstanding any language to the contrary in the Plan, you are prohibited from surrendering Shares that you already own or from attesting to the ownership of Shares to pay any tax withholding in connection with Performance RSUs granted to you.

12.No Fractional Shares. Notwithstanding anything to the contrary in the Plan, no payment or other compensation shall be provided with respect to fractional Shares, which shall be rounded down to the nearest whole number of Shares.

13.Additional Restrictions on Resale. In addition to the restrictions on resale and transfer noted in the Plan materials, securities purchased under the Plan may be subject to certain restrictions on resale imposed by Canadian provincial securities laws. You are encouraged to seek legal advice prior to any resale of such securities. In general, participants resident in Canada may resell their securities in transactions carried out on exchanges outside of Canada and, in particular, you are generally permitted to sell Shares acquired pursuant to the Plan through the designated broker appointed under the Plan, if any, provided that BWXT is a foreign issuer that is not public in Canada and the sale of the Shares acquired pursuant to the Plan takes place: (i) through an exchange, or a market, outside of Canada on the distribution date; or (ii) to a person or company outside of Canada. For purposes hereof, a foreign issuer is an issuer that: (a) is not incorporated or existing pursuant to the laws of Canada or any jurisdiction of Canada; (b) does not have its head office in Canada; and (c) does not have a majority of its executive officers or directors ordinarily resident in Canada.

14.Tax Reporting. You acknowledge that the Tax Act and the regulations thereunder require a Canadian resident individual (among others) to file an information return disclosing prescribed information where, at any time in a tax year, the total cost amount of such individual’s “specified foreign property” (which includes shares, options, restricted stock units, and performance-based restricted stock units) exceeds Cdn.$100,000. You acknowledge having had the opportunity to consult your own tax advisor regarding this reporting requirement and agree that such requirement is solely your responsibility.

15.Non-Qualified Security. In the event that BWXT or the Employer is at any time concurrent with a grant of a Performance RSU a “specified person” as defined in subsection 110(0.1) of the Tax Act, each Share subject to such Performance RSU is hereby designated a “non-qualified security” within the meaning of section 110 of the Tax Act.
