Fresh quarterly results from CoreWeave, Super Micro Computer (Supermicro) and Lumentum indicate that investment in AI infrastructure remains robust. All three companies reported substantial revenue growth and marked improvements in profitability, suggesting there is no immediate slowdown in data‑centre spending.
CoreWeave: revenue soars, backlog signals sustained demand
AI cloud provider CoreWeave reported second‑quarter revenue rising from $1.21 billion a year earlier to $2.58 billion, an increase of 113 percent. Adjusted EBITDA climbed from $753 million to $1.51 billion (about a 101 percent rise). The company remained unprofitable on a GAAP basis, recording a net loss of $626 million, partly due to elevated financing costs.
Management said short‑term available capacity is essentially sold out, and order backlog stood at $104 billion at the end of June. The market reaction was immediate: CoreWeave shares rose more than 18 percent in pre‑market trading.
Super Micro Computer: strong top line and improving margins
Server and AI‑server maker Super Micro Computer reported quarterly revenue of $11.1 billion, up from $5.8 billion a year earlier — an increase of over 91 percent. Profitability improved notably: gross margin rose from 9.5 percent to 17.5 percent (an 8 percentage‑point improvement), while net income increased from $195 million to $1.18 billion, roughly a 500 percent jump.
This improvement is significant because Supermicro’s earlier challenge was not demand but how much profit it could retain from rapidly growing sales. For fiscal 2027 the company expects revenue of $65–72 billion; compared with the just‑closed year’s $39.1 billion in sales, the midpoint of that range would imply roughly a 75 percent additional increase. Supermicro shares gained about 9 percent in pre‑market trading.
Lumentum: optical component demand doubles, margins expand
Optical networking equipment supplier Lumentum posted quarterly revenue up 109 percent year‑on‑year to $1.01 billion — more than double. Profitability improved sharply: adjusted operating margin rose from 15 percent to 36.6 percent (a 21.6 percentage‑point increase). Adjusted earnings per share increased from $0.88 to $3.23, an increase of about 267 percent.
Lumentum expects revenue of $1.23–1.28 billion for the next quarter. Its results illustrate that the AI investment wave extends beyond chips: as GPU clusters scale up, demand for high‑speed optical interconnects inside data centres is rising. Lumentum shares strengthened nearly 8 percent in pre‑market trading.
Conclusion: sustained demand and improving profitability across the AI supply chain
Taken together, the three reports point to continued strong demand for AI infrastructure and improving profitability for many suppliers. Backlogs, management guidance and market reactions all indicate ongoing investment to expand data‑centre capacity — a trend benefiting server manufacturers, optical component makers and cloud providers.
