PREFORMED LINE PRODUCTS ANNOUNCES RECORD SECOND QUARTER 2026 FINANCIAL RESULTS

CLEVELAND, OHIO – July 29, 2026 - Preformed Line Products Company (NASDAQ: PLPC) today reported record financial results for its second quarter of 2026.

Q2 2026 highlights:

•Record quarterly net sales of $212.7 million, an increase of 25% from Q2 2025 and 21% from Q1 2026.

•Record quarterly USA sales, with growth of 32% from Q2 2025 and 12% from Q1 2026, driven by robust demand in energy markets, with communications markets also providing increases.

•Gross profit margin of 34.3%, up 160 basis points from Q2 2025 and 300 basis points from Q1 2026.

•Record quarterly diluted EPS of $4.49 per share, up 75% from Q2 2025 and more than doubling from Q1 2026.

Net sales in the second quarter of 2026 were $212.7 million compared to $169.6 million in the second quarter of 2025, a 25% increase. PLP-USA continued its strong 2026 performance driven primarily by growth in energy sales. All International segments also contributed, with each segment increasing sales from Q2 2025. The Americas segment also benefited from the acquisition of Delta Star Conetores Electricos Ltda ("Delta Star") in May 2026. Foreign currency translation increased second-quarter 2026 net sales by $6.0 million.

Net income for the quarter ended June 30, 2026, was $21.5 million, or $4.49 per diluted share, compared to $12.7 million, or $2.56 per diluted share, for the comparable period in 2025. The increase in net income was primarily driven by higher sales volumes, favorable product mix, fixed cost leverage and the benefit of price increases enacted in 2025. This increase was partially offset by increases in selling costs and investments in personnel supporting strategic market growth in our core product offerings, primarily for sales, sales support and engineering resources. Tariff headwinds also continued to impact net income. Foreign currency translation had a favorable impact of $0.5 million on the second quarter of 2026 net income.

Net sales increased 22% to $389.0 million for the first six months of 2026 compared to $318.1 million for the first six months of 2025. All segments realized a year-over-year increase in net sales due to higher volumes of energy and communications sales, driven most significantly by PLP-USA with a 29% net sales growth. Foreign currency translation rates increased net sales by $13.2 million for the six months ended June 30, 2026.

Net income for the six months ended June 30, 2026, was $32.0 million, or $6.62 per diluted share, compared to $24.2 million, or $4.89 per diluted share, for the comparable period in 2025. The increase in net income was due to higher sales volumes and the benefit of price increases enacted in 2025, partially offset by higher personnel and selling costs, tariff expenses and a higher effective tax rate for the six-month period. Foreign currency translation had a favorable impact of $0.7 million on six-month 2026 net income.

"What a quarter! I am so proud of our global team's execution, which delivered record second-quarter and first-half results," said Rob Ruhlman, Executive Chairman. "Our quarterly net sales and EPS, the highest in the Company's history, reflect the strength of demand in our core energy and communications markets and the resilience of our global operations. Our steadfast commitment to domestic manufacturing continues to provide a strategic advantage, with PLP-USA delivering exceptional 32% sales growth in the quarter. Our international segments continued to provide strong contributions, with each segment providing sales increases. In a very challenging operating environment, I am most encouraged by our 300-basis-point improvement in gross profit margin in Q2 2026 compared to Q1 2026, reflecting the effectiveness of our pricing strategies, supply chain discipline, and ongoing investment in operational efficiency. Our balance

sheet remains a source of strength, providing flexibility to pursue strategic growth opportunities while continuing to invest in our people and facilities. In the second quarter, we welcomed Delta Star, located in Salto, Brazil, to the PLP family. Delta Star provides significant operational support to accelerate growth in our U.S. substation business while also expanding our substation portfolio in the South American region."

"While we celebrate a record second quarter, we remain vigilant in monitoring the evolving tariff and geopolitical landscape, and I believe our significant U.S. manufacturing footprint, diversified global operations, and financially sound position make us well-equipped to navigate these challenges and continue investing in our business. Our focus is unchanged: provide our customers with the high-quality products and superior customer service they have come to expect from PLP.”
