Lumentum Fell 31% From Its High While Revenue Grew 90% in the Same Quarter

The chart above shows Lumentum (LITE) moving in sharp cycles over the past year rather than climbing steadily. Drawdowns of 10% to 20% recurred between last September and this spring, each followed by a recovery toward new highs.

That pattern changed in March, when Lumentum’s stock fell nearly 30% in a single stretch before recovering again into May. The current drawdown, sitting around 31% as of early July, is the deepest of the past year, and Lumentum has yet to fully recover from it.

That pattern changed in March, when the stock fell nearly 30% in a single stretch before recovering again into May. The current drawdown, at around 31% as of the start of July, is the deepest in the past year and has not yet been fully offset.

What makes this drawdown different from the others is timing. It’s happening in the same window, the company just reported its strongest quarter on record. Fiscal third quarter 2026 revenue came in at $808.4 million, up 90% year over year.

Non-GAAP gross margin expanded to 47.9%, up more than 12 percentage points from a year ago, and non-GAAP operating margin reached 32.2%, up more than 21 percentage points over the same period. GAAP net income flipped from a loss of $44.1 million a year ago to a profit of $144.2 million.

Those are not the numbers of a business under strain. They point to a business scaling faster than its cost structure is growing, which is usually a sign of durable operating leverage rather than a temporary spike.

Guidance for the fourth quarter points to more of the same. Management expects revenue between $960 million and $1.01 billion, along with a non-GAAP operating margin of 35% to 36%.

CEO Michael Hurlston specifically called out co-packaged optics and optical circuit switches as growth drivers that have barely begun contributing, suggesting the current pace isn’t simply the company riding past a peak.

Operating Margin Collapsed to 3% in 2024, Then TIKR’s Estimates Show a Sharp Rebound

Lumentum’s margin history over the past five years tells the story of a business that experienced a genuine downturn before this recovery began.

EBIT margin sat around 31% in both 2021 and 2022, then fell to around 19% in 2023 before collapsing to under 3% in 2024, a period when demand for optical components softened broadly across the industry. Margin recovered modestly to under 10% in 2025.

TIKR’s estimates now show a sharp reversal from that trough, with EBIT margin projected to climb back toward 29% in 2026 and continue expanding toward the low 40s by 2028. The actual results from the most recent quarter support that trajectory rather than undermine it.

Non-GAAP operating margin of 32.2% in fiscal Q3 already sits ahead of the annual estimate line, and management’s Q4 guidance of 35% to 36% would push the full year further in that direction. The question worth watching isn’t whether the recovery is real.

It’s whether the current pace of margin expansion, which has been unusually steep, moderates to a more sustainable pace as the AI datacenter buildout matures.

TIKR’s Model Shows a Wide Range of Outcomes, Here’s What Drives the Difference

TIKR’s mid-case model targets Lumentum at around $3,250 by mid-2031, implying a total return of around 350% and an annualized return of around 45%. That is an unusually large figure, and it deserves context rather than a face value reading.

It reflects a scenario in which revenue growth averages around 57% per year over the forecast window, and net income margin expands to around 35%, both of which are extrapolations of the acceleration Lumentum is showing right now, carried forward over several years.

Whether that scenario plays out depends on how durable AI data center demand for optical components proves to be, and how well Lumentum executes on capacity and new-product ramps, such as co-packaged optics.

The Street’s own consensus target of around $1,110 is far more conservative, which highlights how much the outcome depends on which growth assumptions an investor finds credible.

TIKR’s model isn’t a prediction so much as a framework for thinking through what would need to be true for the stock to compound at that rate, and the gap between the model and the Street target is a useful gauge of how much of that growth is already priced in.

Should You Invest in Lumentum Stock

Lumentum’s pullback looks more like a reset in a volatile, high multiple stock than a signal that the underlying business has weakened. Revenue is accelerating, margins are recovering from a real 2024 trough, and management points to next-generation product categories that are still early in their ramp.

The risk is that a business capable of moving from a 3% operating margin to over 30% in two years can move in the other direction just as quickly if AI infrastructure spending slows or competition intensifies in the optical components market.

For investors comfortable with that volatility, the current price sits well below both the Street’s target and TIKR’s longer-term model.
