Cautionary Statement Regarding Forward-Looking Statements This communication contains statements that constitute “forward-looking statements” within the meaning of the Private Securities Litigation Reform Act of 1995, Section 27A of the Securities Act of 1933 and Section 21E of the Securities Exchange Act of 1934, each as amended. All statements other than statements of historical fact, including statements regarding market and industry prospects and future results of operations or financial position, made in this communication are forward-looking. In many cases, you can identify forward-looking statements by terminology, such as “may”, “should”, “expects”, “intends”, “plans”, “anticipates”, “believes”, “estimates”, “predicts”, “potential” or “continue” or the negative of such terms and other comparable terminology. Statements in this communication that are forward looking may include, but are not limited to, statements regarding the benefits of the proposed acquisition of Haynes International, Inc. (“Haynes”) by North American Stainless, Inc. (“Parent”) and the associated integration plans, expected synergies and capital expenditure commitments, anticipated future operating performance and results of Haynes, the expected management and governance of Haynes following the acquisition and expected timing of the closing of the proposed acquisition and other transactions contemplated by the merger agreement governing the proposed acquisition (the “Merger Agreement”). There may also be other statements of expectations, beliefs, future plans and strategies, anticipated events or trends and similar expressions concerning matters that are not historical facts. Readers are cautioned that any such forward-looking statements are not guarantees of future performance and involve risks and uncertainties, many of which are difficult to predict and are generally outside Haynes’ control, that could cause actual performance or results to differ materially from those expressed in, or implied or projected by, the forward-looking statements. Such risks and uncertainties include, but are not limited to: the occurrence of any event, change or other circumstance that could give rise to the right of Haynes or Parent or both of them to terminate the Merger Agreement, including circumstances requiring a party to pay the other party a termination fee pursuant to the Merger Agreement; the failure to obtain applicable regulatory or Haynes stockholder approval in a timely manner or otherwise; the risk that the acquisition may not close in the anticipated timeframe or at all due to one or more of the other closing conditions to the transaction not being satisfied or waived; the risk that there may be unexpected costs, charges or expenses resulting from the proposed acquisition; risks related to the ability of Haynes and Parent to successfully integrate the businesses and achieve the expected synergies and operating efficiencies within the expected timeframes or at all and the possibility that such integration may be more difficult, time consuming or costly than expected; risks that the proposed transaction disrupts Haynes’ or Parent’s current plans and operations; the risk that certain restrictions during the pendency of the proposed transaction may impact Haynes’ or Parent’s ability to pursue certain business opportunities or strategic transactions; risks related to disruption of each company’s management’s time and attention from ongoing business operations due to the proposed transaction; continued availability of capital and financing and rating agency actions; the risk that any announcements relating to the proposed transaction could have adverse effects on the market price of Haynes’ and/or Parent’s common stock, credit ratings or operating results; the risk that the proposed transaction and its announcement could have an adverse effect on the ability of Haynes and Parent to retain and hire key personnel, to retain customers and to maintain relationships with each of their respective business partners, suppliers and customers and on their respective operating results and businesses generally; the risk of litigation that could be instituted against the parties to the Merger Agreement or their respective directors, managers or officers and/or regulatory actions related to the proposed acquisition, including the effects of any outcomes related thereto; risks related to unpredictable and severe or catastrophic events, including but not limited to acts of terrorism, war or hostilities, cyber attacks, or the impact of the COVID-19 pandemic or any other pandemic, epidemic or outbreak of an infectious disease in the United States or worldwide on Haynes’ or Parent’s business, financial condition and results of operations, as well as the response thereto by each company’s management; and other business effects, including the effects of industry, market, economic, political or regulatory conditions. Also, Haynes’ actual results may differ materially from those contemplated by the forward-looking statements for a number of additional reasons as described in Haynes’ filings with the Securities and Exchange Commission (the “SEC”), including those set forth in the Risk Factors section and under any “Forward-Looking Statements” or similar heading in Haynes’ most recently filed Annual Report on Form 10-K filed November 16, 2023 and Haynes’ Current Reports on Form 8-K. Haynes has based these forward-looking statements on its current expectations and projections about future events. Although Haynes believes that the assumptions on which the forward-looking statements contained herein are based are reasonable, any of those assumptions could prove to be inaccurate. As a result, the forward-looking statements based upon those assumptions also could be incorrect. Except to the extent required by law, Haynes undertakes no obligation to publicly update or revise any forward-looking statements, whether as a result of new information, future events or otherwise.
