Rogers Corp

Rogers produces high-frequency laminates, ceramic substrates, and elastomeric foams used in electric vehicles, 5G telecom infrastructure, aerospace radar systems, and industrial equipment. Its best-known products are the RO4000® series circuit materials and curamik® ceramic substrates for power modules. The company does not sell finished consumer goods — its output goes entirely into other manufacturers' products as intermediate components.

Capital allocation decisions — including manufacturing capacity expansion, R&D budget setting, and M&A — are made by the CEO and CFO with oversight from a public-company board of directors. As a listed manufacturer, Rogers does not operate an investment portfolio; its corporate development function acquires complementary materials businesses, such as the 2021 purchase of Silicone Engineering Ltd. for $30 million to expand its elastomer portfolio.

As a publicly traded company, Rogers files quarterly with the SEC, disclosing segment revenue, operating margins, and material customer concentrations. This offers a transparency that private industrial companies and family-owned manufacturers rarely provide. The trade-off is quarterly earnings pressure, which has occasionally led to activist investor attention — Starboard Value LP took a roughly 6.5% stake in 2023 and pushed for operational improvements.

Rogers has been in a net simplification posture since 2023. It divested the non-core polyolefin business in November 2024 for roughly $110 million, exited certain lower-margin product lines, and consolidated some manufacturing steps. Simultaneously, it has added capacity for curamik® substrates in Germany to meet EV power-module demand, reflecting a deliberate shift toward higher-margin, application-specific materials.

The company's materials go into four primary verticals. Automotive accounts for roughly 35%-40% of revenue — mostly silicone foams for EV battery cell compression pads and ceramic substrates for traction inverters. Aerospace and defense contribute around 25% via radar-facing laminates and satellite communications substrates. Telecommunications infrastructure — 5G base station antennas — is approximately 15%-20%. The remainder is general industrial, including mass transit, renewable energy, and medical devices. The company has publicly stated it does not focus on consumer electronics.
