Forward-looking statements include all statements that do not relate solely to historical or current facts, and you can identify forward-looking statements because they contain words such as "believes," "expects," "may," "will," "outlook," "should," "seeks," "intends," "trends," "plans," "estimates," "projects" or "anticipates" or similar expressions that concern our strategy, plans, expectations or intentions. All statements made relating to our estimated and projected earnings, margins, costs, expenditures, cash flows, growth rates and financial results are forward-looking statements. Such forward-looking statements include but are not limited to statements about the benefits of the Transaction, including future financial and operating results, the combined company's plans, objectives, expectations and intentions, and other statements that are not historical facts.  These forward-looking statements are subject to risks, uncertainties and other factors that may cause our actual results, performance or achievements to be materially different from future results, performance or achievements expressed or implied by such forward-looking statements. We derive many of our forward-looking statements from our operating budgets and forecasts, which are based upon many detailed assumptions. While we believe that our assumptions are reasonable, it is very difficult to predict the effect of known factors, and, of course, it is impossible to anticipate all factors that could affect our actual results. In light of the significant uncertainties inherent in the forward-looking statements included herein, the inclusion of such information should not be regarded as a representation by us or any other person that the results or conditions described in such statements or our objectives and plans will be realized. Important factors could affect our results and could cause results to differ materially from those expressed in our forward-looking statements, including but not limited to the factors discussed in the section entitled "Risk Factors" in Summit's Annual Report on Form 10-K for the fiscal year ended December 31, 2022, as filed with the SEC, and any factors discussed in the section entitled "Risk Factors" in any of our subsequently filed SEC filings (including the Proxy Statement); and the following: (i) the risk that the benefits from the Transaction may not be fully realized or may take longer to realize than expected, including as a result of changes in, or problems arising from, general economic and market conditions, interest and exchange rates, monetary policy, laws and regulations and their enforcement, and the degree of competition in the geographic and business areas in which we and Cementos Argos operate; (ii) the ability to promptly and effectively integrate our business and the businesses of Cementos Argos; (iii) reputational risk and potential adverse reactions of our or Cementos Argos's customers, employees or other business partners, including those resulting from the completion of the Transaction; (iv) the dilution caused by our issuance of additional shares of capital stock in connection with the Transaction; (v) the diversion of management's attention and time from ongoing business operations and opportunities on Transaction-related matters; and (vi) the impact of the global COVID-19 pandemic on our or Cementos Argos's businesses, the ability to complete the Transaction or any of the other foregoing risks.

All subsequent written and oral forward-looking statements attributable to us, or persons acting on our behalf, are expressly qualified in their entirety by these cautionary statements.
