Bank of America has strong message for Marvell stock investors

Marvell Technology (MRVL) has given its investors plenty to cheer about amid a remarkably choppy AI trade.

Shares of the AI giant have surged over 160% in the past six months, according to Seeking Alpha data, as demand for its data center chips has fueled optimism. According to a note shared with TheStreet, after meeting CEO Matt Murphy and CFO Dan Durn, Bank of America's Vivek Arya sees plenty of reasons to continue doubling down on the stock.

The momentum has continued of late as well. Shares have surged nearly 12% through September 11, while peers like Nvidia (NVDA) shed over 5% in value over the past week.

For perspective, Marvell is involved in building the machinery behind AI. It designs custom processors and the chips that move data between them and allow massive computing systems to work together efficiently.

Its expanded Google partnership, as reported by Yahoo Finance, in particular drew attention, covering chips that support the search giant's AI infrastructure. Also, that agreement grants Google the right to scoop up Marvell shares at a certain price, contingent on future purchases.

But Arya's latest comments, following a management lunch, reach beyond a specific customer.

BofA underscored a growing portfolio of products that could deepen Marvell's role in AI systems. With an October 6 analyst day approaching, investors could soon get an even clearer view of how massive that opportunity could become.

Why BofA is doubling down on Marvell stock

Bank of America has maintained its Buy rating and lofty $365 price target on Marvell stock, implying nearly 55% upside from Marvell's September 11 closing price near $236.10.

More Wall Street:

Analysts led by Vivek Arya base their conviction on how much more technology Marvell could sell within each AI system.

Arya and his team argue that Marvell's biggest opportunity involves supporting the chips that connect processors, manage memory, and move data. That business is a lot harder for customers to replicate than the processors themselves.

Marvell is already shipping these products to the four major U.S. hyperscalers, and each of its custom processors requires one or two supporting chips, which carry a $500 to $1,500 price tag, creating new opportunities for Marvell to earn revenue from its customers as they expand their compute capacity.

BofA estimates this supporting-chip market alone might exceed $60 billion–$65 billion by 2030. At a projected 40%–50% share, Marvell's annual sales opportunity could potentially rise to $30 billion, compared to the management's $3 billion–$4 billion-plus outlook for 2028.

Additionally, custom processors offer another major growth driver.

BofA sees $15 billion in potential Marvell sales there by 2030, which brings the combined opportunity to $40 billion–$45 billion. It's important to note, though, that these are modeled opportunities, not exactly booked orders.

Also, the earnings implications underscore that enthusiasm.

Arya sees calendar-2028 earnings power near $14 a share, compared to $11 baseline, with each additional $1 billion in sales adding 30–35 cents.

His target uses 33 times baseline earnings, excluding stock compensation. The bull case, therefore, depends heavily on substantial growth and on investors sustaining a premium valuation as Marvell executes.

For perspective, its five-year non-GAAP price-to-earnings ratio is 42 times, so a 33-times baseline is not quite as demanding, according to Seeking Alpha data.

What could derail Marvell's rally

Marvell's biggest risk is the gap between its tremendous market opportunity and the earnings it actually delivers.

BofA's massive $40 billion–$45 billion sales scenario depends a ton on market expansion, customer spending, and substantial share price gains. The sales are still in the future.

Customer execution is arguably the first test.

BofA flags uncertainty around next-generation Amazon and Microsoft chip projects. A delayed launch might push sales outward as development costs continue, weakening the earnings growth investors are anticipating.

Competition will likely compound that exposure.

Broadcom (AVGO) remains perhaps the most formidable custom-chip incumbent, while standard AI processors are competing for the same spending budgets. Marvell's broad connectivity portfolio offers multiple routes to growth, but winning business doesn't exactly guarantee pricing power or the margins BofA's earnings assumptions require.

Moreover, the Google agreement also deserves careful reading.

The much-talked-about $120 billion price tag entails a purchase-linked framework instead of guaranteed orders. Nearly 59 million shares could be issued under the warrant, creating potential dilution alongside the commercial opportunity, as skeptically noted by my colleague Peace Longe.

Valuation leaves another pressure point.

BofA's target is 33 times calendar-2028 earnings, significantly above its cited historical median of 26 times. So that lofty target suggests investors need to continue rewarding Marvell with a premium. Slower growth could hurt both earnings estimates and the multiple applied to them.

As a result, the October 6 analyst day needs to be judged on delivery schedules, margin expectations, and customer ramps. Bigger market forecasts alone can offer limited reassurance following such a rally.

The strongest confirmation might then be clearer evidence that sales growth potentially translates into durable earnings and cash flow per share.
