Luxfer Holdings PLC filed a Form 8-K with the SEC on October 26, 2026, voluntarily supplementing its Definitive Proxy Statement to address allegations in two shareholder lawsuits and multiple demand letters related to its pending acquisition by Double Eagle Acquisition Buyer, Inc.

Key Highlights

  • Two lawsuits filed: Purported shareholders filed actions in the Supreme Court of the State of New York, captioned Johnson v. Luxfer Holdings PLC, No. 162890/2026, and Thompson v. Luxfer Holdings PLC, No. 655883/2026.
  • Allegations: The actions allege the Definitive Proxy Statement omits material information and seek, among other things, an injunction, rescission, or damages if the Transaction is consummated.
  • Company position: According to the filing, Luxfer "believes that the allegations in the Actions and the Shareholder Letters are without merit and that no further disclosure is required under applicable law."
  • Voluntary supplements: The company determined to voluntarily supplement the Definitive Proxy Statement, stating this is done "solely in order to avoid the risk that the Actions and the Shareholder Letters delay or otherwise adversely affect the consummation of the Transaction."
  • Shareholder meetings unchanged: The filing states the Supplemental Disclosures "will not change the consideration to be paid to the Company's shareholders in connection with the Transaction or the timing of the Meetings," which remain scheduled for November 4, 2026.
  • Board recommendation unchanged: The Company Board continues to recommend shareholders vote "FOR" each of the proposals described in the Definitive Proxy Statement.
  • DCF disclosure added: Deutsche Bank's discounted cash flow analysis applied discount rates of 12.5% to 14.5%, and the filing provides an expanded definition of how unlevered free cash flow was calculated for the period from April 1, 2026 through 2030.

Luxfer Discloses Shareholder Actions and Supplemental Proxy Details Ahead of November 4 Vote

According to the filing, Luxfer Holdings PLC (NYSE:LXFR) entered into a Transaction Agreement with Double Eagle Acquisition Buyer, Inc., a Delaware corporation described as "a newly formed holding company owned by funds managed by Wynnchurch Capital, L.P.," pursuant to which the buyer will acquire the entire issued share capital of Luxfer. The transaction is structured as a court-sanctioned English law scheme of arrangement under Part 26 of the Companies Act 2006, as previously disclosed in a Form 8-K filed July 27, 2026.

Following the filing of the Definitive Proxy Statement on September 17, 2026, the company disclosed that two lawsuits were filed by purported shareholders against Luxfer and members of its board in the Supreme Court of the State of New York. The company also reported receiving demand letters from purported shareholders alleging deficient disclosures in both the Preliminary and Definitive Proxy Statements. The filing notes it is possible "additional, similar complaints may be filed, the Actions may be amended, or additional demand letters from purported shareholders may be received."

The Supplemental Disclosures address two areas of the Definitive Proxy Statement. The first clarifies that certain standstill provisions in confidentiality agreements entered into during the sale process "would fall away after Luxfer entered into a definitive agreement with a third party providing for a change of control transaction," and that "none of the confidentiality agreements entered into by Luxfer in connection with the sale process contained a 'don't ask, don't waive' provision." The second provides additional detail on Deutsche Bank's discounted cash flow methodology, including the components used to calculate unlevered free cash flow for Q2-Q4 2026 and for the years 2027 through 2030. The filing states that nothing in it "shall be deemed an admission of the legal necessity or materiality under applicable law of any of the Supplemental Disclosures."

What Was Disclosed

Luxfer filed a supplemental disclosure to its Definitive Proxy Statement, reporting two shareholder lawsuits and demand letters alleging proxy omissions, while affirming the company denies all allegations, maintaining its board recommendation and the November 4, 2026 shareholder meeting dates without change.
