Morning movers: Lumentum rises 8.0% as AI optics accelerate

The Morning Read has today’s CPI and broader market context. This stock brief uses delayed Nasdaq pre-market quotes at 05:43 ET on 12 August 2026, independently checked against TradingView.

LITE: +8.03% as optical demand reaches the rack

Lumentum reported $1.0063 billion of fiscal-Q4 revenue, up 109.3% from a year earlier and 24.5% sequentially. GAAP gross margin rose to 47.4%, from 33.3% a year ago. Management tied the acceleration to AI-network optics, including 1.6-terabit cloud modules and lasers for co-packaged optics. Its fiscal-Q1 revenue outlook of $1.225-$1.275 billion put the midpoint at $1.25 billion. That combination supports a revenue-and-margin re-rating rather than a move based only on sentiment.

• Objective levels: the $863.60-$897.00 delayed range, then Tuesday’s $820.59 close.
• Main risk: guidance depends on customers converting large AI-optics demand into shipments while Lumentum scales supply without giving back its margin gains.

SMCI: +8.67% as sales and gross margin jump together

Supermicro’s preliminary fiscal-Q4 release showed $11.1 billion of net sales, versus $5.8 billion a year earlier. GAAP gross margin reached 17.5%, versus 9.5%, while diluted GAAP earnings were $1.62 per share. For fiscal 2027, management projected $65-$72 billion of net sales. The stock’s reaction reflects more than server volume: the margin recovery suggests a richer customer mix and better economics on complete data-centre systems. Still, the company labelled the figures preliminary and disclosed an independent review related to export-control transactions.

• Objective levels: the $34.03-$35.11 delayed range and Tuesday’s $31.60 close.
• Main risk: final results or the independent review could change the interpretation of today’s preliminary numbers and outlook.

BORR: -9.86% as refinancing overwhelms fleet expansion

Borr Drilling reported $232.3 million of Q2 operating revenue, down 6% from Q1. Adjusted EBITDA fell 51% sequentially to $43.8 million, and the net loss widened to $241.4 million. The largest stated driver was a $176.3 million debt-extinguishment charge from refinancing. The company also highlighted $541 million of year-to-date day-rate-equivalent backlog and a subsequent $287 million joint-venture purchase of five jack-up rigs. The negative reaction says the market is weighing near-term earnings and financing costs against longer-run fleet scale.

• Objective levels: the $3.80-$3.96 delayed range and Tuesday’s $4.26 close.
• Main risk: management said Middle East conflict has reduced near-term visibility for tenders and contract starts.

Also on the radar

• CRWV +17.33% at $105.97 near 05:43 ET: record Q2 revenue and a $104 billion backlog are covered in today’s Morning Read rather than repeated here. CRWV is on Eddie’s watchlist.
• NBIS +9.34% at $211.28 near 05:43 ET: Nebius scheduled Q2 results for 08:00 ET, so the move preceded the official package and remains a binary-event signal, not a confirmed earnings reaction. NBIS is on the watchlist.

What to watch today

• 08:00 ET — Nebius call: compare the official Q2 release with the pre-release NBIS move; do not infer results from the tape.
• 08:30 ET — U.S. CPI: the Morning Read covers the macro event; watch whether the stock-specific gaps hold after the release.
• 09:30 ET — opening auction: compare first regular-session prints with every delayed range above.
• After the open — option chains: rebuild bids, asks and implied volatility; Cboe totals are prior-session context only.
