NGK Corporation (5333.T) : juste valeur

Thèse ACCE

NGK Corporation makes ceramic components that sit inside a wide range of industrial and automotive equipment, most visibly spark plugs and oxygen sensors for combustion engines, along with ceramic substrates and sensors for industrial processes. Its moat rests on decades of materials science and high-volume manufacturing that few rivals can match at the same quality, which gives it pricing power and an entrenched position with OEM customers. The near-term story is a mix of steady demand from industrial ceramics and the company's efforts to broaden beyond combustion-engine parts as the auto industry electrifies, though that transition is a real risk to the core franchise. Revenue grew 10.6% and the operating margin sits at 17.7%, with a gross margin of 30.3%, which is solid for a manufacturer of this type. The stock trades at 24.2 times trailing earnings and 23.6 times forward, a premium that assumes the company can keep growing while its legacy product line shrinks, which is the central question for a deeper look.
