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

Q1 2026 highlights:

•Quarterly net sales of $176.3 million, an increase of 19% from Q1 2025.

•USA sales growth of 26% from Q1 2025, driven by robust demand in energy and communications markets.

•Gross profit margin of 31.3%, up 150 basis points from Q4 2025.

•Diluted EPS of $2.14 per share, up 24% from Q4 2025.

Net sales in the first quarter of 2026 were $176.3 million compared to $148.5 million in the first quarter of 2025, a 19% increase. All segments recorded sales growth compared to the first quarter of 2025, with the PLP-USA business growing by 26%, primarily due to higher demand for energy and communications products. Foreign currency translation had a favorable impact of $7.2 million on the first quarter of 2026 net sales.

Net income for the quarter ended March 31, 2026, was $10.5 million, or $2.14 per diluted share, compared to $11.5 million, or $2.33 per diluted share, for the comparable period in 2025. While gross profit was up approximately $6.5 million from Q1 2025, period expenses were impacted by increased personnel costs supporting strategic market growth in core product offerings in both energy and communications, primarily for sales, sales support and engineering resources. Net income for the first quarter of 2026 was affected by an income tax charge of $1.3 million related to PLP's French subsidiary. Foreign currency translation had a favorable impact of $0.1 million on the first quarter of 2026 net income. Compared against Q4 2025, which contained many of the same tariff headwinds that impacted Q1 2025, gross profit margins, net income, and diluted EPS all increased.

"As we reflect on the first quarter of 2026, I am proud of the Company’s continued resilience in a challenging and dynamic global environment," said Rob Ruhlman, Executive Chairman. "Our team achieved exceptional sales growth this quarter, propelled by outstanding results from our U.S. manufacturing operations and our ability to meet rising demand. We faced margin pressure from higher manufacturing and ongoing tariff-related costs, as well as volatility in commodity prices. However, our impressive 150 basis point increase in gross profit percentage from Q4 2025 shows that we are actively managing these challenges through supply chain optimization, pricing strategies, and investment in efficiency and innovation. Our healthy balance sheet and strong liquidity provide flexibility to pursue strategic acquisitions, while also investing in facility modernization and returning capital to our valued shareholders. While the ongoing tariff and geopolitical uncertainties present challenges, I believe our team is well prepared to adapt.

Our focus is unchanged: provide our customers with the high-quality products and superior customer service they have come to expect from PLP."
