Holders of Accepted Notes will receive the Consideration, plus accrued and unpaid interest on such Accepted Notes from the last interest payment date to, but not including, November 13, 2026, the second business day following the Expiration Time (the \u201cSettlement Date\u201d). Interest will cease to accrue on the Settlement Date for all Accepted Notes. Accepted Notes purchased in the Offers will be cancelled.<\/p>\n \nBWXT has also received the Requisite Consents to adopt the Proposed Amendments with respect to each Series of Notes. BWXT has executed and delivered to the trustee a New Supplemental Indenture to each Indenture. The New Supplemental Indentures became effective upon execution and the Proposed Amendments will become operative when the Notes with respect to which Consents have been delivered are paid for on the Settlement Date.<\/p>\n \nBWXT\u2019s obligation to accept for purchase, and to pay for, Notes and Consents validly tendered or delivered and not validly withdrawn or revoked pursuant to the Offers and the Solicitations is subject to the satisfaction or waiver of certain conditions described in the Statement, including the successful completion of the New Notes Offering and certain general conditions, each as described in the Statement. BWXT may waive any condition, in whole or in part, with respect to either or both Series. No assurance can be given that the New Notes Offering will be completed. The New Notes Offering is not conditioned upon the consummation of the Offers and the Solicitations.<\/p>\n \nBWXT has retained D.F. King & Co., Inc. as the tender and information agent, and J.P. Morgan Securities LLC as the sole dealer manager and the sole solicitation agent, for the Offers and the Solicitations.

This press release shall not constitute an offer to buy or a solicitation of an offer to sell any Notes, a solicitation of Consents with respect to the Notes or the Proposed Amendments, or an offer to sell or the solicitation of an offer to buy any other securities, including the New Notes. The New Notes to be issued in the New Notes Offering have not been and will not be registered under the U.S. Securities Act of 1933, as amended (the \u201cSecurities Act\u201d), or the securities laws of any state or other jurisdiction, and may not be offered or sold in the United States or to U.S. persons absent registration or an applicable exemption from, or in a transaction not subject to, the registration requirements of the Securities Act and applicable state securities laws. In no event will the information contained in this press release regarding the New Notes Offering constitute an offer to sell or a solicitation of an offer to buy any securities in the New Notes Offering.<\/p>\n \nNo representation is made as to the correctness or accuracy of the CUSIP numbers listed in this press release or printed on the Notes. They are provided solely for the convenience of the reader.<\/p>\n Forward-Looking Statements<\/b><\/p>\n This press release contains forward-looking statements based on BWXT\u2019s current expectations and assumptions. These include statements about the conduct, terms, timing and completion of the Offers and the Solicitations, the operativeness of the Proposed Amendments, the proposed New Notes Offering, and the intended use of the net proceeds from the New Notes Offering. Forward-looking statements can generally be identified by words such as \u201cestimate,\u201d \u201cproject,\u201d \u201cpredict,\u201d \u201cbelieve,\u201d \u201cexpect,\u201d \u201canticipate,\u201d \u201cplan,\u201d \u201cseek,\u201d \u201cgoal,\u201d \u201ccould,\u201d \u201cintend,\u201d \u201cmay,\u201d \u201cwould,\u201d \u201cshould,\u201d \u201cwill\u201d or other words that convey the uncertainty of future events or outcomes, although not all forward-looking statements contain these words. Forward-looking statements involve known and unknown risks, uncertainties and other factors, many of which are beyond BWXT\u2019s control, that could cause actual results to differ materially from those expressed or implied. These factors include market conditions, prevailing interest rates and fluctuations in the price of U.S. Treasury securities. They also include BWXT\u2019s ability to complete the New Notes Offering on acceptable terms or at all and the satisfaction or waiver of the conditions to the Offers and the Solicitations. As a contractor to the U.S. Government, BWXT is also subject to risks that include, without limitation, budget uncertainty, the risk of future budget cuts, the impact of continuing resolution funding mechanisms and the debt ceiling, the risk of government shutdowns, including the risk of program cancellations, schedule delays, production halts and other disruptions and nonpayment and changing funding and acquisition priorities. For more information on these and other risks and uncertainties, see \u201cRisk Factors\u201d in BWXT\u2019s Annual Report on Form 10-K for the year ended December 31, 2025 and its subsequent filings with the Securities and Exchange Commission. You should not place undue reliance on forward-looking statements, which speak only as of the date of this press release. Except as required by applicable law, BWXT does not intend, and undertakes no obligation, to update or revise any forward-looking statement to reflect events or circumstances after the date of this press release, whether as a result of new information, future events or otherwise.<\/i><\/p>\n About BWXT<\/i><\/b><\/p>\n At BWX Technologies, Inc.
