~~Appointment~~Set forth below are unaudited preliminary estimated financial results for the Company, based on information available to us as of ~~John~~the ~~Krenicki~~date of this Current Report on Form 8-K. The amounts set forth below are subject to revision based upon the completion of our quarter-end financial closing process, a final review by our management, as ~~Interim~~well ~~President~~as the related external review of our results of operations for the three months ended March 31, 2025 and ~~Chief~~the ~~Executive Officer~~preparation of full financial statements and related notes. The unaudited preliminary estimated financial information included in this Current Report on Form 8-K has been prepared by, and is the responsibility of, our management. Deloitte & Touche LLP has not audited, reviewed, compiled or applied agreed-upon procedures with respect to the preliminary financial information. The processes the Company has used to produce the unaudited preliminary estimated financial information required a greater degree of estimation and assumptions than required during a typical period end closing process. During the completion of such procedures and preparation, the Company may identify additional items that require adjustments to the unaudited preliminary estimated financial information presented below. The unaudited preliminary estimated financial information should not be considered a substitute for the financial statements for the three months ended March 31, 2025 prepared in accordance with U.S. generally accepted accounting principles (“U.S. GAAP”) once they become available. Therefore, investors should not place undue reliance on the unaudited preliminary estimated financial information below. The preliminary results presented below are not necessarily indicative of any future period or our full fiscal year 2025 and should be read together with the Company’s audited consolidated financial statements and related notes and other financial information reported in the Annual Report on Form 10-K for the fiscal year ended December 31, 2024. The Company undertakes no obligation to update or revise these amounts as a result of new information or otherwise.

The Company’s Board of Directors has appointed John Krenicki, the Chairman of the Board, to serve as the Company’s Interim President and Chief Executive Officer as of the effective date of Ms. Lee’s resignation. The Board has engaged a nationally recognized firm to conduct a search for Ms. Lee’s successor.

~~Departure~~Non-GAAP ofFinancial ~~Wayne F. Irmiter as Chief Accounting Officer of the Company~~Measures

OnThis ~~March 18~~Current Report on Form 8-K includes estimates of Pro Forma Net Sales, ~~2025~~Adjusted EBITDA and Pro Forma Adjusted EBITDA, ~~Wayne F~~which are not financial metrics prepared in accordance with U.S. ~~Irmiter~~GAAP and, as a result, are considered non-GAAP financial measures. Our non-GAAP financial measures are not intended to replace the ~~Company’s~~presentation ~~Senior~~of ~~Vice~~the ~~President~~comparable measures under U.S. GAAP. However, ~~Chief~~we ~~Accounting~~believe ~~Officer~~the ~~departed~~presentation of the ~~Company~~non-GAAP financial measures, when considered together with the comparable U.S. GAAP financial measures, assist investors in understanding the factors and trends affecting our underlying business that could not be obtained absent these disclosures. Additionally, we believe that the presentation of our non-GAAP financial measures enables investors to evaluate trends in the business excluding certain items which are not entirely a result of base operations.

~~SIGNATURE~~Furthermore, the presentation of this non-GAAP financial measure supplements other metrics we use to internally evaluate our business and facilitates the comparison of past and present operations. The non-GAAP financial measures we use may differ

~~Pursuant~~from tonon-GAAP ~~the~~financial ~~requirements~~measures ofused ~~the~~by ~~Securities~~other ~~Exchange~~companies ~~Act~~and ofother ~~1934, the~~companies ~~registrant~~may ~~has~~not ~~duly~~define ~~caused~~non-GAAP ~~this~~financial ~~report~~measures towe beuse ~~signed~~in ~~on its behalf by~~ the ~~undersigned~~same ~~thereunto duly authorized~~way.

~~Date:~~A ~~March 21~~reconciliation of Adjusted EBITDA and Pro Forma Adjusted EBITDA to Operating Income is included in this Current Report on Form 8-K because we are unable to quantify certain amounts that would be required to be included in Net Income without unreasonable effort and, ~~2025~~as such, we believe a reconciliation of Adjusted EBITDA and Pro Forma Adjusted EBITDA to Net Income would imply a degree of precision that would be confusing or misleading to investors.
