Forward-Looking Statements

This Form 10-K and other documents filed with the Securities and Exchange Commission (“SEC”) contain forward-looking statements regarding Preformed Line Products Company’s (the “Company”) and the Company’s management’s beliefs and expectations. Any forward-looking statements are made pursuant to the safe harbor provisions of the Private Securities Litigation Reform Act of 1995. 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. Use of words such “anticipates,” “believes,” “may,” “should,” “will,” “would,” “could,” “plans,” “projects,” “expects,” “estimates,” “predicts,” “targets,” “forecasts,” “intends,” “contemplates,” and similar words may identify forward-looking statements. Such forward-looking statements are subject to uncertainties and factors relating to the Company’s operations and business environment, all of which are difficult to predict and many of which are beyond the Company’s control. Such uncertainties and factors could cause the Company’s actual results to differ materially from those matters expressed in or implied by such forward-looking statements.

The following factors, among others, could affect the Company’s future performance and cause the Company’s actual results to differ materially from those expressed or implied by forward-looking statements made in this report:

•The overall demand for cable anchoring and control hardware for electrical transmission and distribution lines on a worldwide basis, which has a slow growth rate in mature markets such as the United States (“U.S.”), Canada, Australia and Western Europe and may grow slowly or experience prolonged delay in developing regions despite expanding power needs;

•The potential impact of global economic conditions, including the impact of inflation, tariffs and rising interest rates, on the Company’s ongoing profitability and future growth opportunities in the Company’s core markets in the U.S. and other foreign countries, which may experience continued or further instability due to political and economic conditions, social unrest, acts of war, military conflict (including the ongoing Russian-Ukrainian and Israeli-Palestinian conflicts), international hostilities or the perception that hostilities may be imminent, terrorism, changes in diplomatic and trade relationships and public health concerns (including viral outbreaks such as COVID-19);

•The ability of the Company’s customers to raise funds needed to build the infrastructure projects their customers require;

•Technological developments that affect longer-term trends for communication lines, such as wireless communication;

•The decreasing demand for product supporting copper-based infrastructure due to the introduction of products using new technologies or adoption of new industry standards;

•The Company’s success at continuing to develop proprietary technology and maintaining high quality products and customer service to meet or exceed new industry performance standards and individual customer expectations;

•The Company’s success in strengthening and retaining relationships with the Company’s customers, growing sales at targeted accounts and expanding geographically;

•The extent to which the Company is successful at expanding the Company’s product line or production facilities into new areas or implementing efficiency measures at existing facilities;

•The effects of fluctuation in currency exchange rates upon the Company’s foreign subsidiaries’ operations and reported results from international operations, together with non-currency risks of investing in and conducting significant operations in foreign countries, including those relating to political, social, economic, trade and regulatory factors;

•The Company’s ability to identify, complete, obtain funding for and integrate acquisitions for profitable growth;

•The potential impact of consolidation, deregulation and bankruptcy among the Company’s suppliers, competitors and customers and of any legal or regulatory claims;

•The relative degree of competitive and customer price pressure on the Company’s products;

•The cost, availability and quality of raw materials required for the manufacture of products and any tariffs that may be associated with the purchase of these products or components of these products. The Company’s supply chain could face disruptions and constraints from inflationary pressures and ongoing wars and military conflicts, which could have a material, adverse effect on the ability to secure raw materials and supplies;

•Strikes, labor disruptions and other fluctuations in labor costs;

•Changes in significant government regulations, including those affecting environmental compliance or regulatory or third-party litigation matters;

•Security breaches or other disruptions to the Company’s information technology structure;

•The telecommunication market’s continued deployment of Fiber-to-the-Premises;

•The impact of any failure to timely implement and maintain adequate financial, information technology and management processes and controls and procedures; and

•Those factors described under the heading “Risk Factors” on page 9.

In light of these risks and uncertainties, the Company cautions you not to place undue reliance on these forward-looking statements. Any forward-looking statements that the Company makes in this report speaks only as of the date of such statement, and the Company undertakes no obligation to update any forward-looking statement or to publicly announce the results of any revision to any of those statements to reflect future events or developments. Comparisons of results for current and any prior periods are not intended to express any future trends or indications of future performance, unless specifically expressed as such, and should only be viewed as historical data.
