Forward-Looking Statements

This annual report and the documents incorporated or deemed to be incorporated by reference therein contain statements concerning our future results and performance and other matters that are “forward-looking” within the meaning of Section 27A of the Securities Act of 1933 and Section 21E of the Securities Exchange Act of 1934. These forward-looking statements are intended to provide management's current expectations or plans for our future operating and financial performance, based on assumptions currently believed to be valid. Forward-looking statements may be identified by the use of terminology such as “believe,” “expect,” “anticipate,” “intend,” "seek," "target," "approximately," “estimate,” “plan,” “project,” “may,” “will,” "would," “should,” "could," or the negative of such words or other comparable terminology in connection with a discussion of future operating or financial performance. The discussion of financial outlook, trends, strategy, plans, assumptions, or intentions may also include forward-looking statements. Readers should not place undue reliance on forward-looking statements, such as financial performance forecasts, which speak only as of the date they are first made. Because forward-looking statements are subject to risks and uncertainties, actual results may differ materially from those expressed or implied by the forward-looking statements. There are a number of risks, uncertainties, and other important factors that could cause actual results to differ materially from those projected, anticipated, or implied, including, but not limited to:

•Conditions in the industries in which our Machine Clothing and Albany Engineered Composites segments compete, along with the general risks associated with macroeconomic conditions, including higher interest rates, inflationary pressures, or the effects of another pandemic, for an extended period of time;

•Across the entire Company, increasing labor, raw material, energy, and logistic costs due to supply chain constraints and inflationary pressures. These challenges have only increased as a result of the ongoing Russia-Ukraine war and the conflict in the Middle East;

•Across both segments, potential port strikes could cause additional disruptions to our supply chain;

•Harm caused by changes in our relationships or contracts with suppliers and customers;

•In the Machine Clothing segment, greater than anticipated declines in the demand for publication grades of paper, or lower than anticipated growth in other paper grades;

•In the Albany Engineered Composites segment, longer-than-expected timeframe for the aerospace industry to utilize existing inventories, and unanticipated reductions in demand, delays, technical difficulties or cancellations in aerospace programs that are expected to generate revenue and drive long-term growth;

•Inability of our Machine Clothing or Albany Engineered Composite segments to create additional production capacity in a timely manner or the occurrence of other manufacturing or supply difficulties (including as a result of geopolitical crises, natural disaster, public health crises and epidemics/pandemics, regulatory or otherwise);

•Changes in geopolitical conditions impacting countries where the Company does or intends to do business;

•Failure to achieve or maintain anticipated profitable growth;

•Failure to achieve our strategic initiatives and other goals, including, but not limited to, our sustainability goals;

•In the Albany Engineered Composites segment, the estimates and expectations based on aircraft production rates provided by Airbus, Boeing and others;

•In the Albany Engineered Composites segment, risks and uncertainties associated with the successful implementation and ramp up of significant new programs, including the ability to manufacture the products to the detailed specifications required and recover start-up costs and other investments in the programs;

•In the Albany Engineered Composites segment, risks associated with changes in estimates and assumptions that could result in a decline in program gross margins or turn a profitable program into a loss program;

•Adverse impacts from inflation, an economic slowdown or recession and by disruption in capital and credit markets that might impede our access to credit, increase our borrowing costs and impair the financial soundness of our customers and suppliers;

Index

•With the change in the United States Presidential Administration, proposed tariffs by the new Administration that may significantly and adversely impact our results of operations;

•Expectations regarding our ability to attract, motivate, and retain the workforce necessary to execute our business strategy;

•Adverse impacts from fluctuations in foreign currency exchange rates;

•Harm caused by large customer purchase reductions, payment defaults or contract non-renewal;

•In the Albany Engineered Composites segment, future funding and compliance risks associated with our contracts with government entities, OEM customers or prime contractors on contracts with governmental agencies;

•Costly and disruptive legal disputes and settlements;

•Future levels of indebtedness and capital expenditures;

•Adverse impacts from changes in tax legislation or challenges to our tax positions;

•Cybersecurity incidents or significant computer system compromises or data breaches;

•Significant problems with information systems or networks;

•Failure to successfully integrate the Heimbach Group companies into our business systems and processes within the expected timeframe or, failure to or delayed realization of anticipated benefits of the acquisition could adversely impact the Company’s business, financial condition and results of operations; and

•Other risks and uncertainties detailed in this report and other periodic reports.

Further information concerning important factors that could cause actual events or results to be materially different from the forward-looking statements can be found in “Business Environment Overview and Trends” in Item 7, Management's Discussion and Analysis of Financial Condition and Results of Operations, as well as in Item 1A, Risk Factors. Although we believe the expectations reflected in our forward-looking statements are based on reasonable assumptions, it is not possible to foresee or identify all factors that could have a material and negative impact on our future performance. The forward-looking statements included or incorporated by reference in this annual report are made on the basis of our assumptions and analyses, as of the time the statements are made, in light of our experience and perception of historical conditions, expected future developments, and other factors believed to be appropriate under the circumstances, except as otherwise required by law. We undertake no obligation to publicly update or revise any forward-looking statements, whether as a result of new information, future events, or otherwise, except as required by applicable law.
