The global industrial automation and PLC market just received a powerful confirmation signal from the supply chain. NN Inc. (NASDAQ: NNBR) reported Q1 2026 earnings on May 9, revealing that its Power Solutions segment—a critical supplier of precision components to industrial automation, electrical control, and PLC manufacturing sectors—posted a staggering 27% year-over-year revenue surge to $55.4 million. This isn't just a single-company success story; it represents a tangible, upstream indicator that demand for programmable logic controllers and industrial control systems is accelerating at a pace that warrants serious attention from OEMs, integrators, and procurement strategists alike.
Analyst Insight: NN Inc.'s Power Solutions segment serves as a bellwether for the industrial automation supply chain. When a Tier-2 precision components supplier posts 27% growth with expanding margins, it signals that Tier-1 PLC manufacturers and control system OEMs are ramping production to meet surging end-market demand. This data point aligns with broader macro trends of reshoring, smart factory investment, and energy infrastructure modernization.
The Numbers Behind the Surge
NN Inc. reported consolidated net sales of $118.5 million for Q1 2026, representing a 12.1% increase year-over-year. The standout performer was unquestionably the Power Solutions segment, which delivered $55.4 million in net sales—a 27% leap driven by higher volumes, an improved product mix, and favorable foreign exchange tailwinds.
Adjusted EBITDA for Power Solutions reached $10.4 million, translating to an 18.7% margin. This marks a dramatic 65.1% improvement from the $6.3 million and 14.5% margin recorded in the same quarter a year ago. The margin expansion suggests not only rising demand but also operational leverage kicking in as production volumes scale.

Why Power Solutions Growth Matters for PLC and Industrial Automation Markets
The Power Solutions segment manufactures precision-engineered components—including electrical contacts, connectors, bus bars, and power management assemblies—that feed directly into the production lines of major industrial automation equipment manufacturers. These components are essential building blocks for PLC hardware, motor control centers, industrial power supplies, and automated control cabinets deployed across factory floors worldwide.
When an upstream supplier like NN Inc. reports 27% volume-driven growth, it indicates that PLC manufacturers and industrial control system integrators are pulling more components through the supply chain. This demand pull typically precedes—or confirms—a capital expenditure upcycle in discrete manufacturing, process automation, and energy management sectors.
Market Trend: The industrial automation components market is projected to grow at a CAGR exceeding 8% through 2030, fueled by Industry 4.0 adoption, the expansion of smart grid infrastructure, and increasing investment in semiconductor fabrication facilities. NN Inc.'s Q1 results provide an early, data-backed signal that this growth trajectory remains firmly intact—and may be accelerating.
The margin expansion story is equally significant. Power Solutions' adjusted EBITDA margin jumped 420 basis points to 18.7%, suggesting that the industrial automation supply chain is absorbing higher production volumes efficiently. For buyers and procurement managers, this signals that component suppliers have capacity headroom to meet rising demand without immediate pricing pressure—though sustained growth could tighten lead times in the quarters ahead.
Full-Year 2026 Guidance Upgrade Reinforces Bullish Outlook
In a move that underscores management's confidence in the industrial automation demand cycle, NN Inc. raised its full-year 2026 guidance concurrent with the Q1 earnings release. The upward revision reflects sustained order book strength across Power Solutions' end markets, including factory automation, electrical infrastructure, and renewable energy control systems.
The guidance raise is particularly noteworthy given ongoing macroeconomic uncertainties. NN Inc.'s willingness to project higher full-year performance suggests that the demand signals observed in Q1 are not transient—they represent a structural expansion in the industrial automation components market that is expected to persist through the remainder of 2026.
What This Means for PLC Buyers and Procurement Teams
For procurement professionals sourcing PLC hardware and industrial control systems, NN Inc.'s results carry three actionable implications:
1. Lead times may extend. As component suppliers operate at higher utilization rates, standard lead times for PLC hardware, I/O modules, and related control equipment could stretch. Early ordering and safety stock strategies are advisable.
2. Pricing stability—for now. The margin expansion at NN Inc. indicates operational efficiency gains are offsetting input cost pressures. However, sustained demand could shift pricing leverage toward suppliers in the second half of 2026.
3. Diversify sourcing. With demand accelerating, single-sourcing strategies for critical automation components carry elevated risk. Procurement teams should evaluate alternative suppliers and qualify secondary sources for PLC-related precision components.
Frequently Asked Questions
How does NN Inc.'s Power Solutions segment relate to the PLC market?
NN Inc.'s Power Solutions segment manufactures precision electrical components—such as contacts, connectors, and bus bar assemblies—that are integrated into programmable logic controllers (PLCs), motor control centers, industrial power supplies, and related automation hardware produced by major OEMs in the industrial control sector.
Is the 27% growth sustainable for the industrial automation supply chain?
NN Inc.'s raised full-year 2026 guidance suggests management believes the growth is sustainable through year-end. The 65% EBITDA increase and expanding margins indicate that the demand is volume-driven rather than price-driven, which historically correlates with durable industrial investment cycles rather than short-term inventory restocking.
What end-markets are driving Power Solutions growth?
The segment serves multiple industrial automation end-markets including factory automation, electrical infrastructure and smart grid, renewable energy control systems, semiconductor manufacturing equipment, and general industrial motion control. The breadth of end-market exposure diversifies the growth drivers beyond any single sector.
Should PLC buyers expect price increases following these results?
Near-term pricing appears stable given NN Inc.'s margin expansion through operational efficiency. However, if demand continues accelerating through Q2 and Q3 2026, component suppliers across the industrial automation value chain may gain pricing leverage. Procurement teams should monitor quarterly earnings from other automation component suppliers for confirmation of broader pricing trends.
The Bottom Line
NN Inc.'s Q1 2026 earnings deliver a clear, data-driven message: the industrial automation and PLC market is experiencing robust, volume-led growth that extends deep into the supply chain. The 27% surge in Power Solutions revenue—coupled with significant margin expansion and an upward guidance revision—provides procurement professionals, system integrators, and OEM strategists with a compelling reason to reassess sourcing strategies and capacity planning for the balance of 2026 and beyond.
