Modine Manufacturing (MOD)

The sleeper story is that Modine hit 94% organic data center growth but is already guiding for deceleration, suggesting either capacity constraints or conservative sandbagging; either way, the liquid cooling CDU product that was supposed to launch this year just slipped to 'first shipments' in Q4. The Street celebrates 138% data center growth and 10th straight quarter of margin beats, but the binding constraint is becoming clear: they can't build capacity fast enough and their next-gen liquid cooling product isn't ready, evidenced by the 'test phase' language replacing 'production' language. Most revealing quote: 'as fast as they add the capacity, we're taking orders and shipping' which sounds great until you realize it means zero inventory buffer and likely lost sales. My view changes if they announce a major capacity addition with specific timeline or if CDU ships earlier than Q4 with actual revenue attached.
