Read MoreHide Full Article
Shares of Preformed Line Products Company (PLPC - Free Report) have surged 104.7% over the past year, significantly outperforming the sub-industry’s 32.7% return. The rally has coincided with record sales, stronger profitability and broad-based demand across the company’s energy and communications markets.

PLPC is also expanding its manufacturing footprint and strengthening its international operations through acquisitions and capacity investments. With operating momentum remaining healthy and financial flexibility supporting further expansion, the factors behind the stock’s strong run merit a closer look.
What’s Fueling PLPC’s Growth?
Energy demand remains at the center of PLPC’s operating momentum. Second-quarter 2026 net sales reached a record $212.7 million, increasing 25% year over year and 21% from the first quarter. PLP-USA generated record quarterly sales of $104.3 million, up 32% year over year and 12% sequentially, primarily reflecting higher energy volumes.
Energy sales rose 25% year over year and 19% sequentially to $148.9 million, with transmission demand continuing to support growth. Communications operations provided an additional tailwind. PLP-USA communications sales increased 19% sequentially, driven by strong demand for fiber-closure products, while EMEA communications sales advanced 24% year over year.
The benefits are extending beyond the top line. Gross margin improved to 34.3%, up 160 basis points year over year and 300 basis points sequentially. The second quarter marked the fourth consecutive quarter of gross-margin improvement.
Higher volumes, favorable product mix, price increases implemented in 2025 and improved fixed-cost leverage helped net income reach $21.5 million. EPS climbed 75% year over year to a record $4.49.
Expansion Efforts Add Another Growth Layer
Beyond organic demand, PLPC is broadening its growth platform geographically. All international segments delivered year-over-year sales growth in the second quarter of 2026. The Americas and EMEA recorded quarterly sales growth of 19% and 31%, respectively, reaching record levels.
The May 2026 acquisition of Delta Star expands PLPC’s substation connector capabilities and strengthens its presence in the South American energy market. Delta Star generated $1.2 million in sales during the quarter and is also providing operational support for the expansion of the U.S. substation business.
Capacity expansion is another important part of the strategy. On July 21, 2026, PLP Canada acquired a facility and related property for approximately $16.7 million. The facility will replace its existing operation while expanding manufacturing capacity and supporting future growth initiatives.
In Poland, PLPC is financing construction of a new manufacturing plant through a loan facility of up to approximately $26.7 million. Together, these investments give the company additional capacity to address demand across energy and communications infrastructure markets.
Balance Sheet Provides Room to Invest
The expansion strategy is supported by a healthy liquidity position. As of June 30, 2026, PLPC held $76.2 million in cash and cash equivalents.
Only $6.7 million of its $60 million global credit facility was drawn, leaving $53.3 million available. The bank debt-to-equity ratio stood at 8.6%.
Cash-generation trends have also strengthened. Operating cash flow totaled $31.3 million during the first six months of 2026, while second-quarter free cash flow improved to $18.3 million from negative $3.9 million in the first quarter. Free cash flow conversion reached 85%.
This financial flexibility allows the company to fund manufacturing investments and acquisitions while continuing to pay its regular dividend.
Is the Valuation Still Supportive?
Despite the stock’s substantial appreciation, PLPC currently trades at a trailing 12-month enterprise value-to-EBITDA multiple of 20.13, below the broader industry average of 33.81.
The valuation therefore remains notable given the company’s record sales, improving margins, international expansion and strong energy-market demand.

The Bottom Line
PLPC’s share-price rally is being backed by improving fundamentals rather than stock momentum alone. Strong transmission demand is driving the energy business, communications activity is providing additional support and international operations are expanding.
At the same time, the Delta Star acquisition and manufacturing investments in Canada and Poland are broadening the company’s growth platform. Improving margins, stronger cash generation and ample liquidity provide additional support for these initiatives.
