CLEVELAND, OHIO – October 29, 2025 - Preformed Line Products Company (NASDAQ: PLPC) today reported financial results for its third quarter of 2025.

Q3 2025 highlights compared to same quarter last year:

•Net sales growth of 21%

•Previously announced U.S. Pension Plan termination successfully completed in Q3, resulting in a non-cash pre-tax charge of $11.7 million

•Fully diluted EPS of $0.53 compared to $1.54 due to pension termination charge

•Adjusted fully diluted EPS, which excludes the pension termination charge, of $2.09, an increase of 36%

Net sales in the third quarter of 2025 were $178.1 million compared to $147.0 million in the third quarter of 2024, a 21% increase. PLP-USA continued its strong 2025 performance as both energy product and communications end-market sales contributed to the increase. The international segments bolstered the sales increase with higher energy product sales as well as incremental communication sales from the recently acquired JAP Telecom. Foreign currency translation increased third-quarter 2025 net sales by $1.9 million.

Net income for the quarter ended September 30, 2025 was $2.6 million, or $0.53 per diluted share, compared to $7.7 million, or $1.54 per diluted share, for the comparable period in 2024. Excluding the non-cash pension plan termination charge, adjusted net income for the quarter ended September 30, 2025 was $10.3 million, or $2.09 per diluted share. In addition to the one-time non-cash pension termination charge, the third quarter of 2025 net income was impacted by the continuing tariffs affecting goods sourced internationally by PLP-USA and tariff-related acceleration of Last-In First-Out (LIFO) inventory valuation costs totaling $3.8 million on a pre-tax basis. These costs were offset by margin contribution from higher sales levels and lower interest expense. Selling price increases announced earlier this year on new orders meant to offset the recently enacted tariffs currently lag the tariff impact on the income statement.

Net sales increased 16% to $496.2 million for the first nine months of 2025 compared to $426.6 million for the first nine months of 2024. All segments realized a year-over-year increase in net sales due to higher volumes of energy and communication market sales. Foreign currency translation rates reduced net sales by $3.0 million for the nine months ended September 30, 2025.

Net income for the nine months ended September 30, 2025 was $26.8 million, or $5.42 per diluted share, compared to $26.6 million, or $5.37 per diluted share, for the comparable period in 2024. Excluding the pension termination charge, adjusted net income for the nine-month ended September 30, 2025 was $34.6 million, or $6.98 per diluted share, a 30% increase. In addition to the pension termination charge, net income for the nine months ended September 30, 2025 was impacted by the recently enacted tariffs, pre-tax LIFO inventory valuation costs of $6.2 million offset by margin contribution from higher sales levels and lower interest expense.

Rob Ruhlman, Executive Chairman, said, “We continue to post quarterly sales gains due to the strength of our core energy and communication end markets. We are very pleased that the sales growth is global, benefiting the USA energy and communications business as well as sales growth in all international segments for the current quarter and full year. While both order quoting and backlog show signs of market strength, the impact on customer demand caused by recently enacted tariffs creates uncertainty. We have incurred cost increases on key commodity inputs necessary for our USA production process, primarily due to Section 232 steel and aluminum tariffs. Earlier this year, we announced selling price increases designed to mitigate the impact of the recently enacted tariffs.

While these selling price increases currently lag the flow through of higher costs associated with tariffs in our income statement, over time, full mitigation is expected. In the third quarter, we also successfully completed the previously announced U.S. Pension Plan termination through the purchase of a group annuity contract. This is another significant step in strengthening and de-risking our balance sheet. Our focus is unchanged: provide our customers with the high-quality products and superior customer service they have come to expect from PLP.”
