Preformed Line Products Q2 earnings

Sales surged 25% year over year and 21% sequentially, setting a new quarterly record for the company. Much of this growth came in the U.S. market, where y-o-y sales growth was 32%.

Gross profit margin inched up 1.6 percentage points to 34.3% year over year, growing 3 points sequentially. Combined with the sales growth, which drove up earnings 75% year over year -- and more than doubled from Q1 2026 -- price increases and higher sales volumes offset headwinds from higher tariff rates.

What's next for PLP?

Management did not provide guidance in its earnings release, but did say that a combination of strong U.S. demand and a focus on U.S. manufacturing is helping to drive growth. (It's also probably helping avoid some tariffs!)

One area of growth investors should keep an eye on lies south of the border, where PLP recently acquired Brazilian wire producer Delta Star. The company expects this acquisition to help accelerate growth in sales to electrical substations in the U.S. -- and also grow international sales in South America."

On the minus side, data from S&P Global Market Intelligence show that operating profit margins in the Americas, ex-U.S.A., are currently less than half of U.S. margins. Investors will want to look for improvement in that dynamic, to learn if the Delta Star acquisition will pay off -- or was a mistake.
