After the Bell: Lumentum and Super Micro Ride AI Guidance, Cava Slips on a Beat
Tuesday's closing bell handed the market one of the last busy evenings of the second-quarter season, and the after-hours tape repeated the year's dominant lesson: the guidance paragraph moves the stock. Alongside CoreWeave's closely watched report, covered separately, results from Super Micro Computer, Lumentum, Cava Group and H&R Block sorted winners from losers largely on what management said about the quarters ahead, per Investing.com's after-hours summary.
Lumentum delivered the cleanest beat of the group. The optical components maker earned $3.23 per share in its fiscal fourth quarter against expectations of $2.95, on revenue of $1.01 billion, according to Investing.com. Guidance pointed higher still: management projected first-quarter revenue of $1.23 billion to $1.27 billion and earnings of $4.05 to $4.35 per share, a step up that reflects the datacenter optics demand tied to AI buildouts. Shares added about 0.8% in initial extended trading.
Super Micro Computer's numbers were bigger and its message bolder. The server maker posted fiscal fourth-quarter adjusted earnings of $1.70 per share on revenue of $11.12 billion, per Investing.com, and guided first-quarter revenue to a range of $14.5 billion to $15.5 billion, with a full-year outlook reaching as high as $72 billion. Yahoo Finance reported the stock jumped on the upbeat outlook before settling to a more modest gain of under 1% as the session progressed, a muted close for numbers that size and a hint of how much AI hardware growth is already priced in.
Cava Group showed the other side of the pattern. The Mediterranean fast-casual chain reported quarterly earnings of $0.19 per share on revenue of $365.4 million and guided full-year same-restaurant sales growth of 4.5% to 6.5% with 75 to 77 net new locations, per Investing.com. None of that was a stumble, but shares slipped about 1.3% after hours, the kind of reaction that has met richly valued growth stories all season when guidance merely confirms rather than raises the trajectory.
H&R Block offered a quieter positive. The tax preparer earned $2.38 per share in its fiscal fourth quarter on $1.14 billion of revenue and issued fiscal 2027 guidance of $6.04 to $6.24 in earnings per share with revenue of up to $4.16 billion, according to Investing.com. Shares rose about 1.6%, a straightforward reward for a forward outlook that cleared the bar.
The evening also produced a sympathy trade. Nebius Group, the AI cloud infrastructure provider that competes in CoreWeave's neighborhood, climbed nearly 5% after hours without a report of its own, per Investing.com, as CoreWeave's backlog figures lifted sentiment across the neocloud group.
Taken together, Tuesday evening looked like the season in miniature. Two AI-adjacent hardware names beat and raised and were rewarded only modestly; a high-multiple consumer growth story executed and still drifted lower; and a mature cash generator gained simply by guiding up. Wednesday's session will show whether those initial reactions hold, with Cisco's report after tomorrow's close next in line to test the pattern.
