Mistras Group is rated a buy, driven by recovering upstream oil activity and strategic focus on higher-margin segments like data centers and aerospace. MG's Q1 2026 revenue grew 5% to $169M, with infrastructure and aerospace segments offsetting an 11% oil & gas decline due to exiting low-margin operations. Despite sector-lagging margins and volatile free cash flow, MG's forward EPS growth is projected at 27.55%, and EBITDA growth aligns with sector averages.
