Marvell Technology (MRVL) shares got roughed up Monday after Benchmark yanked its Buy rating and moved the chipmaker to Hold. The culprit? Growing evidence that Marvell has lost a major piece of business with Amazon to Taiwan's Alchip.
What Went Wrong
Benchmark's downgrade came after the firm spent two days at industry meetings and walked away increasingly convinced that Marvell won't be designing Amazon's Tranium 3 and 4 chips. That's a big deal. Analysts at Benchmark said the shift looks tied to Amazon deciding to license Tranium 3 and Tranium 4 SERDES technology from Synopsys instead of relying on Marvell. On top of that, Amazon appears to be working with Alchip for design, foundry, and backend support.
This competitive loss is expected to be the main factor behind Marvell's projected slowdown to roughly 20% XPU growth in calendar year 2026. While Marvell recently assured investors it doesn't expect a revenue "air pocket" next year with its lead XPU customer, Amazon, Benchmark isn't buying it. The firm believes that optimistic outlook is actually driven by expected Tranium 2 volumes and a Kuiper low-earth orbit engagement rather than any successful transition to Tranium 3.
There's more nuance here: Amazon's announced Tranium 3 is currently only the air-cooled version for customer evaluation, with the liquid-cooled variant not expected until at least mid-2026. Benchmark believes Tranium 2 volumes will continue supporting Marvell's near-term forecasts, which explains why the pain isn't immediate.
Looking ahead, Benchmark noted that Marvell's outlook for renewed XPU growth in fiscal 2028 reflects expectations for a new hyperscaler engagement ramping in subsequent years. But with shares performing strongly following recent earnings, the firm recommended investors take near-term profits while they can.
Reading The Charts
The market reaction was swift and brutal. The stock opened at $90.45, climbed to a high of $92.61 on Monday, before tumbling to a low of $88.92 during the session. That's serious volatility. Trading volume spiked to 24.8 million shares, well above average, suggesting plenty of investor anxiety and repositioning.
From a technical standpoint, Marvell is currently trading approximately 2.3% above its 50-day moving average, which could offer some near-term support. But the bigger picture looks rougher: the stock is trading 21.3% below its 200-day moving average, highlighting a longer-term bearish trend that might worry investors. The stock's 52-week range of $47.08 to $127.48 shows just how wild the ride has been.
The drop may have breached key support levels, with immediate support potentially found around that $88.92 low. If that level doesn't hold, traders are eyeing further downside, possibly testing the psychological $85 level. On the upside, resistance likely sits around the recent high of $92.61, which could cap any near-term bounce attempts.
At the time of writing, Marvell shares were trading 6.53% lower at $92.38.
