Forward-looking statements include, among other things, statements regarding guidance, outlook, targets, objectives, future operating performance, cash generation, capital allocation, market conditions and strategic initiatives. These forward-looking statements are subject to risks and uncertainties that could cause actual results to differ from those projected, anticipated, expected or implied. The most significant of these uncertainties are described in Carpenter Technology’s filings with the Securities and Exchange Commission, including its report on Form 10-K for the fiscal year ended June 30, 2026, and the exhibits attached to that filing. They include but are not limited to: (1) the cyclical nature of the specialty materials business and certain end-use markets, including aerospace, defense, medical, energy, transportation, industrial and consumer, or other influences on Carpenter Technology's business such as new competitors, the consolidation of competitors, customers, and suppliers or the transfer of manufacturing capacity from the United States to foreign countries; (2) the ability of Carpenter Technology to achieve cash generation, growth, earnings, profitability, operating income, cost savings and reductions, qualifications, productivity improvements or process changes; (3) the ability to recoup increases in the cost of energy, raw materials, freight or other factors; (4) domestic and foreign excess manufacturing capacity for certain metals; (5) fluctuations in currency exchange and interest rates; (6) the effect of government trade actions, including tariffs; (7) the valuation of the assets and liabilities in Carpenter Technology's pension trusts and the accounting for pension plans; (8) possible labor disputes or work stoppages; (9) the potential that our customers may substitute alternate materials or adopt different manufacturing practices that replace or limit the suitability of our products; (10) the ability to successfully acquire and integrate acquisitions; (11) the availability of credit facilities to Carpenter Technology, its customers or other members of the supply chain; (12) the ability to obtain energy or raw materials, especially from suppliers located in countries that may be subject to unstable political or economic conditions; (13) Carpenter Technology's manufacturing processes are dependent upon highly specialized equipment located primarily in facilities in Reading and Latrobe, Pennsylvania and Athens, Alabama for which there may be limited alternatives if there are significant equipment failures or a catastrophic event; (14) the ability to hire and retain a qualified workforce and key personnel, including members of the executive management team, management, metallurgists and other skilled personnel; (15) fluctuations in oil and gas prices and production; (16) the impact of potential cybersecurity incidents, ransomware attacks, malicious AI usage, operational technology disruptions, information technology failures, data security breaches and failures of third-party technology service providers; (17) the ability of suppliers, logistics providers and other supply-chain participants to meet obligations due to capacity constraints, transportation disruptions, energy shortages, geopolitical events, labor shortages or other factors; (18) the ability to meet increased demand, production targets or commitments; (19) the ability to manage the impacts of natural disasters, climate change, pandemics and outbreaks of contagious diseases and other adverse public health developments; (20) geopolitical, economic, regulatory and security risks relating to our global business, including international conflicts, military actions, diplomatic tensions, trade restrictions, sanctions, disruptions to transportation corridors and shipping routes and changes in U.S. and foreign trade, tax and regulatory requirements; (21) challenges affecting the commercial aviation industry or key participants; (22) the consequences of the announcement, maintenance or use of Carpenter Technology’s share repurchase program; and (23) the ability to successfully execute major capital projects and brownfield expansion initiatives, including achieving expected costs, schedules, capacity additions, productivity improvements and returns on investment. Any of these factors could have an adverse and/or fluctuating effect on Carpenter Technology's results of operations. The forward-looking statements in this document are intended to be subject to the safe harbor protection provided by Section 27A of the Securities Act of 1933, as amended (the "Securities Act"), and Section 21E of the Securities Exchange Act of 1934, as amended.
