Lumentum reported a resilient top-line uptick in QQ2 2025 with revenue of USD 402.2 million, up 9.65% year over year and 19.38% quarter over quarter, underscoring ongoing demand in optical communications and laser technologies. Gross profit was USD 99.6 million, delivering a gross margin of 24.8%, while operating income remained negative at USD -51.6 million, reflecting sustained investment in R&D and go-to-market expenses that offset the revenue growth. EBITDA stood at USD 28.2 million (7.0% margin), yet net income declined to USD -60.9 million, producing an EPS of -0.88. Despite the bottom-line weakness, the company generated USD 24.3 million of operating cash flow and ended the period with USD 479.7 million in cash (and USD 896.7 million in cash and short-term investments) against USD 2.61 billion of total debt, signaling a leveraged but liquid balance sheet.
