Three layers of AI infrastructure grew in the same quarter
Results from Supermicro, CoreWeave and Lumentum show AI infrastructure demand reaching servers, cloud capacity and optical links, while rapid growth produces different cost, margin and profit pictures in each set of accounts.

Demand reaches three separate layers
The three companies' August 11 results show AI data-centre investment expanding across three connected layers. Server maker Supermicro reported fourth-quarter net sales of 11.1 billion dollars, taking full-year sales to 39.1 billion dollars. It said more than 60 billion dollars of new orders arrived during the quarter. Cloud infrastructure provider CoreWeave's second-quarter revenue rose from 1,212 million dollars a year earlier to 2,575 million dollars, while its revenue backlog stood at about 104 billion dollars at the end of June. Optical-link maker Lumentum reported fourth-quarter net revenue of 1,006.3 million dollars, an increase of 109.3 per cent from a year earlier. Chief executive Michael Hurlston connected that demand with data-centre architects turning to optical links as AI workloads increase in speed and bandwidth. The same investment wave therefore appears as server orders at Supermicro, cloud commitments at CoreWeave and connectivity revenue at Lumentum, giving three separate company views of infrastructure demand.[1], [2], [3]
Growth lands differently in the accounts
Revenue growth produced different profit pictures in the three accounts. Supermicro posted a gross margin of 17.5 per cent and GAAP net income of 1,178 million dollars, with GAAP diluted earnings of 1.62 dollars a share. CoreWeave increased revenue by 112 per cent and lifted adjusted EBITDA by 101 per cent to 1,510 million dollars. It nevertheless reported an operating loss of 49 million dollars and a net loss of 626 million dollars, after capital expenditure of 14,117 million dollars in the first 6 months of the year. Lumentum's non-GAAP gross margin was 50.4 per cent and its non-GAAP operating margin was 36.6 per cent. Its GAAP net loss of 7,161.7 million dollars was driven by a non-cash loss of 7.8 billion dollars from converting notes into equity, while non-GAAP earnings came to 3.23 dollars a share. The results show rapid growth moving into the profit line in different ways because of operating structure, capital spending and accounting events.[1], [2], [3]
Forward measures keep the capacity race moving
The companies' forward measures also describe different stops along the demand chain. Supermicro guides to September-quarter net sales of 14.5 billion to 15.5 billion dollars and expects fiscal 2027 sales of 65 billion to 72 billion dollars. CoreWeave said it added more than 25 billion dollars of net new commitments early in the third quarter to a revenue backlog of about 104 billion dollars at the end of June. Lumentum guides to September-quarter revenue of 1.225 billion to 1.275 billion dollars and non-GAAP earnings of 4.05 to 4.35 dollars a share. These measures describe different obligations: an order, a long-term revenue commitment and next-quarter guidance are separate accounting categories. Read together, however, they show customers allocating resources both to computing capacity and to the hardware that connects that capacity. Growth is the common line across the night's results; the distinction lies in how much capital it requires and how quickly revenue reaches profit. Ranking the three companies only by revenue growth would therefore miss the clearest differences in their accounts.[1], [2], [3]
