KeyBanc downgrades Materion on China tariff impacts

KeyBanc last night downgraded Materion (MTRN) to Sector Weight from Overweight without a price target The firm cites its downward earnings revisions and a modestly lower valuation range following the company’s Q1 report for the downgrade. The analyst reduced estimates to reflect Materion’s lower Q1 profit baseline plus relatively penal impacts from China tariffs over the balance of 2025 and 2026. Should macro conditions change, including some secession of China tariffs, KeyBanc would consider becoming more positive, the analyst tells investors in a research note.
