CLEVELAND, OHIO – July 30, 2025 - Preformed Line Products Company (NASDAQ: PLPC) today reported financial results for its second quarter of 2025.

Q2 2025 highlights compared to same quarter last year:

•Net sales growth of 22%

•Gross margin increase of 80 bps

•Net income and fully diluted EPS increase of 35%

Net sales in the second quarter of 2025 were $169.6 million compared to $138.7 million in the second quarter of 2024, a 22% 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 reduced second-quarter 2025 net sales by $0.5 million.

Net income for the quarter ended June 30, 2025, was $12.7 million, or $2.56 per diluted share, compared to $9.4 million, or $1.89 per diluted share, for the comparable period in 2024. The second quarter of 2025 net income was impacted by an increase in gross profit from higher sales levels and lower interest expense, partially offset by higher period expenses and the impact of recently enacted tariffs affecting goods sourced internationally by the USA segment. Gross profit as a percentage of net sales was 32.7% for the second quarter of 2025, an increase of 80 basis points versus the same quarter in 2024.

Net sales increased 14% to $318.1 million for the first six months of 2025 compared to $279.6 million for the first six months of 2024. All segments realized a year-over-year increase in sales due to higher volumes of energy and communication market sales. Foreign currency translation rates reduced net sales by $4.9 million for the six months ended June 30, 2025.

Net income for the six months ended June 30, 2025 was $24.2 million, or $4.89 per diluted share, compared to $19.0 million, or $3.83 per diluted share, for the comparable period in 2024. YTD June 30, 2025 net income was impacted by an increase in gross profit resulting from the increase in sales and lower interest expense, which were partially offset by higher period expenses and increased tariff expense.

Rob Ruhlman, Executive Chairman, said, “Building on a strong Q1 2025, we posted strong sales and earnings gains for Q2 2025. I am most pleased that the sales growth is global, benefiting the USA energy and communications business as well as growth in many of the international operations. While we remain optimistic that our primary end markets will continue to grow, the impact on customer demand caused by recently enacted tariffs creates uncertainty. Our strong commitment to USA manufacturing provides a competitive advantage in the current high-tariff environment, but we will incur certain cost increases related to key commodity inputs necessary for our USA production process, primarily due to Section 232 steel and aluminum tariffs. Through strong execution, we have managed the tariff impact well. We will continue to actively mitigate the impact of higher costs caused by tariffs and other global commodity cost increases by implementing targeted selling price increases and continued focus on cost containment and supply chain strategies. I am also happy to welcome newly acquired JAP Telecom to the PLP family and I am confident in the contributions they will make to our communications product portfolio. Our current focus is unchanged: provide our customers with the high-quality products and superior customer service they have come to expect from PLP.”
