Cautionary Note Regarding Forward-Looking Statements

This press release contains forward-looking statements within the meaning of the “safe harbor” provisions of the Private Securities Litigation Reform Act of 1995. Sizzle II’s, Trasteel’s and/or Pubco’s actual results may differ from their expectations, estimates and projections and, consequently, you should not rely on these forward-looking statements as predictions of future events. Forward-looking statements include statements concerning plans, objectives, goals, strategies, future events or performance, and underlying assumptions, and other statements that are other than statements of historical fact. No representations or warranties, express or implied, are given in, or in respect of, this press release. When words such as “may,” “will,” “intend,” “should,” “believe,” “expect,” “anticipate,” “project,” “estimate” or similar expressions that do not relate solely to historical matters are used, such terms are, among others, used in the context of making forward-looking statements.

These forward-looking statements, and factors that may cause actual results to differ materially from current expectations, include, but are not limited to, the following, which reflect the risk factors described in the Registration Statement:

Risks relating to Trasteel’s business and industry: the tie of Trasteel’s results to cyclical global steel and raw-material prices; the risk that Trasteel’s back-to-back, hedged trading model may not fully offset price risk; global steel oversupply, China’s dominant share of production and shifting trade flows; intense competition and disintermediation; the dependence of Trasteel’s growth strategy on acquiring and integrating industrial assets; geographic concentration of revenues in the European Union, particularly Italy; and tariffs, trade remedies, sanctions and the EU Carbon Border Adjustment Mechanism; dependence on trade-finance and credit facilities;

Risks relating to Pubco’s structure and jurisdiction: Pubco’s status as a Luxembourg company and as a “foreign private issuer,” including its exemption from certain U.S. securities rules and the possible loss of foreign private issuer status; the governance of shareholder rights under Luxembourg law and the differences between Luxembourg and European insolvency laws and those of the United States; the potential difficulty of enforcing judgments against Pubco or its directors, whose assets are located outside the United States; the concentration of ownership of Pubco Ordinary Shares among Trasteel’s principal shareholders following the Business Combination; and identified material weaknesses in internal control over financial reporting and substantial doubt about the ability to continue as a going concern;

Risks relating to the Proposed Business Combination and Sizzle II: the ability of the parties to complete the Proposed Business Combination in a timely manner or at all; the risk that Sizzle II does not consummate the Business Combination by April 3, 2027 and is required to liquidate and dissolve; the failure to obtain the approval of Sizzle II’s shareholders or to satisfy the minimum cash condition or other closing conditions; the level of redemptions by Sizzle II’s public shareholders and the resulting reduction in available cash and working capital and effect on Sizzle II’s strategic plan; conflicts of interest of the Sponsor and Sizzle II’s directors and officers; the ability to obtain and maintain the listing of Pubco Ordinary Shares on Nasdaq; the risks of becoming a public company through a special purpose acquisition company rather than an underwritten offering, including the absence of an underwriter’s independent due diligence review; the costs of the Proposed Business Combination and of operating as a public company; the effect of the announcement or pendency of the Proposed Business Combination on Trasteel’s and Sizzle II’s business relationships, operating results and operations; the absence of a prior public market for, and the potential illiquidity of, Pubco Ordinary Shares, and the effect of future sales of shares; and the intention not to pay dividends; and those factors discussed under the heading “Risk Factors” in the Registration Statement and in the Sizzle II Form 10-K, and other documents Sizzle II has filed, or that Sizzle II or Pubco will file, with the SEC.

The foregoing list of factors is not exhaustive. You should carefully consider the foregoing factors and the other risks and uncertainties described in the “Risk Factors” section of the Registration Statement referenced above, the final prospectus of Sizzle II dated March 31, 2025 and filed with the SEC on April 2, 2025, Sizzle II’s most recent Quarterly Report on Form 10-Q filed with the SEC on August 12, 2026, the Sizzle II Form 10-K, and other documents filed or to be filed by Sizzle II and Pubco from time to time with the SEC. These filings identify and address other important risks and uncertainties that could cause actual events and results to differ materially from those contained in the forward-looking statements. Forward-looking statements speak only as of the date they are made. There may be additional risks that none of Sizzle II, Trasteel or Pubco presently know, or that they currently believe are immaterial, which in each case could cause actual results to differ from those contained in the forward-looking statements. For these reasons, among others, investors and other interested persons are cautioned not to place undue reliance upon any forward-looking statements in this press release. None of Sizzle II, Trasteel or Pubco undertakes any obligation to publicly revise any forward-looking statements to reflect events or circumstances that arise after the date of this press release, except as required by applicable law.
