It entered 2025 after years of losses: in the quarter to September 2024 it reported an operating loss of $72.7 million on revenue of $336.9 million. Its shares fell to an intraday low of $45.65 in April 2025. Revenue then rose each quarter. On 4 November 2025 Lumentum reported quarterly revenue of $533.8 million, up 58% from a year earlier, and guided to more than 20% sequential growth for the next quarter.
