Marvell Stock Hits $170 Resistance as POET Cancellation Clouds AI Roadmap

Marvell Technology (MRVL) is one of the most interesting AI infrastructure plays on Wall Street, but there is a new supply chain issue that the market hasn't fully addressed yet. Shares closed at $164.31 on April 24 and then fell to $160.88 in pre-market trading. They were stuck between RBC Capital Markets' $170 price target and a 6% drop caused by the cancellation of a purchase order with optical component supplier POET Technologies, whose stock dropped about 50% in one day.

Both the POET cancellation and the wider AI infrastructure bull case want the same amount of value. Which story gets more attention will depend on what Marvell says in its next earnings call about the timing for its Celestial AI optical interconnect.

The POET Cancellation: What Happened and Why It Matters

Marvell ended its POET order because procurement and shipping information was shared without permission. This was a clear breach of confidentiality that Marvell had no doubts about upholding. The reasoning can be defended; a business that keeps private information about its supply line from the public is acting logically.

The market is worried not about the breach itself, but about the dependence it showed. POET was giving Marvell's Celestial AI business optical signal transceiver parts. Celestial AI works on optical computing interconnect technology for fast data transfer in Nvidia's AI server clusters. Celestial AI is Marvell's entry into the AI optical networking market. It's the infrastructure that lets GPU clusters connect quickly enough for current AI workloads. If you lose a supplier in the middle of development, the roadmap doesn't stop, but there is a risk to the schedule that the market quickly priced as a 6% discount.

The market is asking about structure: how long does it take to qualify a replacement if Celestial AI's optical connection technology depends on certain features of the parts POET supplied? And does that delay make it harder for Marvell to compete with Broadcom and other optical networking companies?

The answer will depend on what Marvell says on its next earnings call. The market will see the POET event as a supplier management incident, which is already reflected in the 6% drop, if the company names a qualified alternative supplier and confirms that the Celestial AI timeline will not change. Valuation pressure will stay in place if Celestial AI's progress is lowered or if management doesn't say anything.

The Bull Case: Everything Else Is Working

If you take away the POET noise, Marvell's positioning in terms of AI infrastructure is one of the best in the semiconductor industry. The company made a record $8.195 billion in fiscal 2026, which is 42% more than the previous year. CEO Matt Murphy said the rise was due to "robust AI demand." Last quarter, revenue from AI-related activities passed 50% of total revenue. This is the most important metric for proving the company's shift from a niche chip player to an AI infrastructure specialist.

The changes to the strategic relationship have been important. Nvidia gave Marvell $2 billion and said they would work together through the NVLink Fusion platform. This is clear proof of Marvell's role in the high-speed connectivity layer that connects AI computing systems. "The inference inflection has arrived," said Jensen Huang, CEO of Nvidia. He pointed to Marvell's optical interconnect and switching technologies as important building blocks for AI on a large scale.

The April 22 announcement of the Polariton Technologies acquisition directly addresses the Celestial AI optical roadmap. It brings in silicon photonics knowledge that moves data using light instead of electricity, which saves energy and speeds things up. That purchase might end up being more useful for Celestial AI's supplier needs than the POET withdrawal was harmful.

Reports that Google is in talks to make special AI chips add a possible source of income that could be on par with what Broadcom makes from its current relationships with hyperscaler ASIC manufacturers. As is usual before an agreement, both Google and Marvell declined to comment. However, the conversation itself is important because of how big Google is.

The Valuation Debate: Where Targets Actually Sit

The real story about how much optimism is already there is in the analyst goal distribution. RBC Capital Markets raised its price target from $115 to $170 and kept the Outperform rating. After talking with Marvell executives, Oppenheimer also raised its price from $150 to $170. B. Riley changed the price from $135 to $156 and said again "Buy." On the bullish end, those goals are being met by the current share price. This means that the most hopeful predictions made by institutions have already come true.

StockAnalysis tracks 32 experts, and the average price target for Marvell is $120.28. This is a lot less than where the stock is currently trading. One analyst at Seeking Alpha downgraded the stock to "Hold," estimating its fair value to be $132 and pointing out a 138% rise since their last report. Chris Versace of TheStreet Pro sold 415 Marvell shares "at or around $170." He pointed out that the RSI was close to 90, which is a number that usually means momentum is too high, and said the sale was part of his portfolio's discipline after a 125% rise in eight weeks.

There is real uncertainty about how quickly the Google ASIC relationship turns into revenue, whether Celestial AI sticks to its schedule after POET, and whether cloud infrastructure spending stays at levels that justify current multiples. This is reflected in the difference between the $170 bullish calls and the $120 average target.

The most important event is Marvell's next results call. Two specific signs will show if the stock can stay near $170 or if it is about to go through a bigger consolidation. First, any official statement from Celestial AI that a POET replacement is qualified and the schedule for the optical interconnect is still on track. Second, whether AI's share of revenue stays above 50%, which is the level that supports the story of transformation instead of saying that the disruption in the POET is a sign of a broader slowing of momentum.

The bull case, which includes talks about a partnership with Nvidia, the purchase of Polariton, and high sales, is real and built on solid ground. The execution risk, which includes the time it takes to replace POET, a high concentration of customers, and a share price that is already above the most optimistic analyst goals, is just as real. At $160–164, buyers are paying for the bull case to come true with little to no slippage. They'll find out if that premium was worth it on the results call in June.
