Is It Too Early To Buy Marvell Stock After Its Three-Month Fall?

Marvell Technology (MRVL) has more than tripled over the past year. It has also fallen about 28% in three months and trades about 30% below its 52-week high. If you are wondering whether the growth story broke, it did not. Marvell raised its revenue guidance on August 27, 2026, and the stock fell anyway.

What Are You Paying For Marvell Today?

Marvell trades at roughly 32 times the earnings analysts expect for fiscal 2028. Its trailing profit is not a clean yardstick: net margin ran above operating margin, so part of it came from below the operating line, not from the chip business.

Revenue over the last twelve months was about $9.5 billion. Management now guides fiscal 2028 to approximately $18 billion, up from $16.5 billion a quarter earlier. That raise is broad: optical DSPs, scale-up optics, switching and custom silicon are all running ahead of plan.

Why Did Marvell Fall On Better Numbers?

Mix. Marvell guided fiscal Q3 2027 non-GAAP gross margin to a midpoint of 58.0%, below the 58.9% non-GAAP figure it delivered in fiscal Q2 2027. The CFO blamed that step down on the ramp in custom silicon, the chips Marvell designs for hyperscalers. Custom silicon is expected to accelerate through the second half of fiscal 2027.

Consensus has revenue growing 54.7% a year from the last twelve months to fiscal 2028, against 30.6% delivered over the last twelve months. Management guides acceleration too, so the top line is not the stretch. Underneath it, consensus expects earnings to grow faster than revenue between fiscal 2027 and fiscal 2028.

That needs margins to widen. The CFO’s preliminary view is that fiscal 2028 gross margin stays in the same range Marvell exits fiscal 2027 in, and he said it depends on ultimate mix, so the widening in operating margin has to come from the expense line. The CFO guided fiscal 2028 non-GAAP operating expenses to grow at roughly half the rate of revenue, and said that expense restraint is what lifts non-GAAP operating margin to the upper end of its current 38% to 40% long-term target range through fiscal 2028. What the market marked down in August was a bigger revenue number guided alongside a softer gross margin.

Should You Wait For Marvell To Settle The Gross Margin Question?

Marvell will hold an investor day on October 6, 2026. The CFO said the long-term target model gets reset at that event.

Management says that revenue from the expanded hyperscaler agreement it disclosed in August already sits inside the custom target through fiscal 2028, and that the big impact would come in fiscal 2029 and beyond.

Marvell’s report days cut both ways: down 12.3% over the two trading days after its August 27, 2026 report, and up 22.4% over the same window after its March 5, 2026 one. Its worst peak-to-trough fall over the past three years was about 61%, so this drop is no floor on its own. The fall has not broken the growth. It has not answered the gross margin question either. Marvell has put a date on that answer. If a rising guide is what you are buying, check which other companies are raising guidance the same way.

So Do You Buy Marvell Before The Investor Day?

Perhaps, but only if you would still want the shares after a bad reaction. Timing one stock around one presentation is hard, even when the business is winning. If you would rather not make that call at all, look at the Trefis High Quality Portfolio. It holds quality names, sized and rebalanced with discipline, so no single stock decides your year. That portfolio has a track record of outpacing the three major indices.
