Rogers shows a turnaround, not proof yet
- Q1 2026 looked better: net sales rose 5.2% year over year to $200.5 million.
- Gross margin improved to 32.2%, a sharp reset after weak 2025 profitability.
- EMS was the key bright spot, with gross margin rising to 35.4% from 32.3% a year earlier.
- Automotive sales were still lower, so EV and hybrid demand remains the main watch item.
- The 2025 curamik impairment still matters because it points to competition and supply pressure in AES.
A better quarter, with strings attached
Rogers had a real rebound in Q1 2026. Net sales grew 5.2% year over year to $200.5 million, gross margin rose 230 basis points to 32.2%, and operating margin improved to 5.3% from an operating loss of 0.2% a year earlier. That is a clear break from the 2025 story, when sales fell and profitability weakened.
The bull case is that the company is fixing its own problems. EMS gross margin recovered to 35.4% from 32.3%, helped by higher sales volume, better factory use, and favorable product mix. AES also improved, helped by cost savings from manufacturing footprint consolidation.
The bear case is that one strong quarter does not prove a durable turn. Automotive sales were still down in Q1 2026, which matters because EV and hybrid vehicle materials are a major part of the strategy. AES also has a new production line with low utilization, which means the factory is not yet running at the level needed to spread costs well.
Finn's view should stay balanced. The recovery is encouraging, but the score is not high enough to treat Rogers as a clean growth story. The next proof points are simple: keep consolidated gross margin above 32%, show automotive growth again, and explain whether the EMS margin gain can repeat.
Special materials for hard jobs
Rogers makes high-performance engineered materials and components. Customers use them in products where heat, power, signal quality, weight, or reliability matter. That includes electric vehicles, advanced driver systems, aerospace communications, wireless gear, industrial equipment, and portable electronics.
The company makes money by selling these materials into specialized applications. Its edge comes from knowing how the material will perform inside the customer's design, not from selling a basic commodity. Engineers and sales teams work with customers early, which can make relationships sticky if the material gets designed into a product.
That model can break when end markets slow or customers carry too much inventory. It can also break when a new line runs below target use, because fixed factory costs get spread across fewer units. In 2025, Rogers also took a $71.8 million impairment in the AES curamik unit after changing competition and supply dynamics lowered demand and margin forecasts.
Where the materials go
EV and hybrid vehicle materials
Rogers sells battery cell pads, ceramic substrates, and related materials for electric and hybrid vehicles. This is a key growth area, but recent automotive weakness keeps the timing uncertain.
ADAS materials
The company supplies materials for advanced driver-assistance systems, which help cars sense and react to the road. ADAS can grow even when the broader auto cycle is uneven.
Aerospace and defense communications
Rogers sells components used in advanced communication systems for aerospace and defense. This market helped offset weakness in other areas during parts of 2025.
Portable electronics and 5G smartphones
The company provides materials for portable electronics, including 5G smartphones. This can add growth, but consumer electronics demand can move in cycles.
Industrial and electronics applications
Industrial and electronics sales rose in Q1 2026 compared with Q1 2025. This helped offset lower automotive sales in the quarter.
Renewable energy, wireless infrastructure, and transit
Rogers also sells into renewable energy, wireless infrastructure, and mass transit. These markets give the company more ways to grow, but each has its own investment cycle.
AES is still the largest piece
Segment mix is based on Q1 2026 net sales: AES at $107.7 million, EMS at $88.4 million, and Other at $4.4 million. The mix is concentrated in two main segments, so a problem in either one can move total results.
What could still go wrong
Automotive demand stays weak
High impact · Medium oddsAutomotive sales were lower in Q1 2026 compared with Q1 2025. That matters because EV, hybrid, and ADAS materials are central to the growth plan. If vehicle programs are delayed or customers keep reducing inventory, Rogers may not get the volume it needs.
Margin recovery fades
High impact · Medium oddsQ1 2026 gross margin improved to 32.2%, and EMS margin rose to 35.4%. The question is whether that came from lasting fixes or from mix that may not repeat. If the next quarters fall back, the turnaround case weakens fast.
AES utilization stays low
Medium impact · Medium oddsAES margin improved in Q1 2026, but lower utilization on a new production line still held it back. Low utilization means a factory is not making enough volume to spread its fixed costs well. That can limit profit even if demand improves elsewhere.
Competition pressures curamik
High impact · Medium oddsRogers recorded a $71.8 million impairment in 2025 tied to the curamik reporting unit inside AES. Management pointed to changing market competition and supply dynamics. That suggests part of the problem may be structural, not only a short-term downturn.
Tariffs and China trade disrupt sales
Medium impact · Medium oddsRogers has risk from tariffs on goods from Mexico, Canada, and China, and from weaker U.S.-China trade relations. The company also sells into China, so trade limits could hurt revenue or raise costs. Tariffs can also pressure margins if Rogers cannot pass costs to customers.
In one breath
What does Rogers Corporation do?
Rogers makes engineered materials and components for demanding uses. Its products go into electric and hybrid vehicles, driver-assistance systems, aerospace communications, electronics, industrial equipment, and wireless infrastructure.
Is Rogers mainly an EV stock?
EV and hybrid vehicle materials are important to the growth story, but Rogers is not only tied to EVs. It also sells into industrial, electronics, communications, aerospace and defense, renewable energy, and portable electronics markets.
Why did the Rogers thesis improve in Q1 2026?
Sales returned to growth and gross margin improved sharply. EMS was the biggest positive change, with margin rising to 35.4% from 32.3% a year earlier.
What is the biggest concern for Rogers now?
The biggest concern is whether the Q1 rebound can last. Automotive demand is still weak, and the 2025 curamik impairment raises questions about competition and pricing power in part of AES.
