AI Data Center Demand Drives Record Results, But Margin Concerns Linger
AI data center demand fuels record bookings and strong guidance Littelfuse's data center and grid infrastructure sales have grown to about 20% of the business, with bookings up over 20% year over year. Management guided Q3 sales to $780–800 million on record bookings and a book-to-bill well above 1.0, signaling continued momentum that supports the stock price.
This is the core growth engine behind the stock's rally and the strongest new positive catalyst this period.
Q2 beat estimates with 20% revenue growth and margin expansion Littelfuse reported Q2 revenue of $739 million, up 20% year over year and 5.4% above estimates, with adjusted EPS of $4.19 and EBITDA margin improving to 23.6%. The dividend was raised 7%. Strong results and shareholder returns reinforce confidence in the business.
The earnings beat and margin improvement are concrete proof the growth story is translating into profits.
Long-term margin and growth concerns persist Despite the rally, analysts flag that Littelfuse's operating margin has fallen sharply over five years to just 2.8% and revenue growth has averaged only 4.3% annually. Return on invested capital has also declined, raising doubts about whether the recent growth can be sustained profitably.
This is the main counterweight to the bullish narrative and could cap further gains if margins don't recover.
Competitive pressure from larger rival Corning Corning, a much larger competitor, grew revenue 24% over the past two years versus Littelfuse's 17.6%, helped by AI data center partnerships with Nvidia, Broadcom, Meta, Amazon, and Apple. This highlights Littelfuse's relatively smaller scale and slower growth in the same hot market.
Shows Littelfuse may be losing relative ground to a bigger, better-connected rival in the AI data center space.
