As a general matter, forward-looking statements are those focused upon future plans, objectives or performance as opposed to historical items and include statements of anticipated events or trends and expectations and beliefs relating to matters not historical in nature. Such forward-looking statements involve known and unknown risks and are subject to uncertainties and factors relating to Core Molding Technologies' operations and business environment, all of which are difficult to predict and many of which are beyond Core Molding Technologies' control. Words such as “may,” “will,” “could,” “would,” “should,” “anticipate,” “predict,” “potential,” “continue,” “expect,” “intend,” “plans,” “projects,” “believes,” “estimates,” “encouraged,” “confident” and similar expressions are used to identify these forward-looking statements. These uncertainties and factors could cause Core Molding Technologies' actual results to differ materially from those matters expressed in or implied by such forward-looking statements. Core Molding Technologies believes that the following factors, among others, could affect its future performance and cause actual results to differ materially from those expressed or implied by forward-looking statements made in this presentation: business conditions in the plastics, transportation, power sports, utilities and commercial product industries (including changes in demand for truck production); federal and state regulations (including engine emission regulations); general economic, social, regulatory (including foreign trade policy) and political environments in the countries in which Core Molding Technologies operates; changes in U.S. trade policy, including tariffs and related foreign relations; the adverse impact of coronavirus (COVID-19) global pandemic on our business, results of operations, financial position, liquidity or cash flow, as well as impact on customers and supply chains; safety and security conditions in Mexico; fluctuations in foreign currency exchange rates; disruptions in financial markets and the availability and cost of credit; dependence upon certain major customers as the primary source of Core Molding Technologies’ sales revenues; efforts of Core Molding Technologies to expand its customer base and replace lost or transitioning programs; the cyclical nature of the industries and markets we serve; the ability to develop new and innovative products and to diversify markets, materials and processes and increase operational enhancements; ability to accurately quote and execute manufacturing processes for new business; the actions of competitors, customers, and suppliers; failure of Core Molding Technologies’ suppliers to perform their obligations; the availability and pricing of raw materials, including supply chain disruptions and inflationary pressures; long-term fixed price customer contracts; labor relations, labor availability and competition for skilled workers, as well as possible work stoppages or labor disruptions at one or more of our union locations or one of our customer or supplier locations; the loss or inability of Core Molding Technologies to attract and retain key personnel; risks associated with foreign operations in Mexico and Canada; the ability to successfully identify, evaluate and manage potential acquisitions and strategic initiatives; federal, state and local environmental laws and regulations; climate change, weather severity and energy prices; the availability of sufficient capital; the ability of Core Molding Technologies to provide on-time delivery to customers, which may require additional shipping expenses to ensure on-time delivery or otherwise result in late fees and other customer charges; risk of cancellation, delay or change in scope of orders or projects; inadequate insurance coverage to protect against potential hazards; equipment and machinery failure; product liability, recall and warranty claims; the inability to protect proprietary information and intellectual property rights; risks associated with the use of artificial intelligence in our business and operations; cybersecurity incidents; our ability to maintain effective internal control over financial reporting and comply with debt covenants; impairment charges related to goodwill or other intangible assets; tax policy changes or adverse tax audits; stock price volatility; and other risks identified from time to time in Core Molding Technologies’ other public documents on file with the Securities and Exchange Commission, including those described in Item 1A of the December 31, 2025 Annual Report on Form 10-K.
