Like with death and taxes, there are two inalienable truths in investing: hardware businesses earn thin margins and software businesses earn fat ones, because making physical things is costly while selling code that can be copied endlessly is, comparatively speaking, not.
Every so often, though, a company scrambles that neat distinction, and few are doing it more clearly than Sandisk Corporation (NASDAQ: SNDK). The maker of physical flash memory chips recently posted margin numbers that look almost too good for its industry.
Thanks in large part to revenue soaring more than 370% in its earnings report earlier this month, SanDisk’s gross margins hit 85%. For context, that’s a higher gross margin print than the 78% reported by software giant Salesforce Inc (NYSE: CRM), which doesn’t physically manufacture so much as a paperclip.
That combination of explosive growth paired with software-like margins is extraordinarily rare in hardware, and it raises a tantalizing question—has Sandisk stumbled onto one of the most profitable growth stories in the entire technology sector, and if so, can it last?
A Margin Profile That Defies the Category
To appreciate how unusual Sandisk's profitability is, it helps to see it alongside its peers. Traditional storage rivals like Western Digital Corporation (NASDAQ: WDC) and Seagate Technology (NASDAQ: STX) typically run gross margins in the region of 40% to 50%, and the wider hardware sector often far less.
Sandisk, with its margins at 85%, is in a different league entirely, which helps explain why its stock is up 540% for the year, versus 180% for Western Digital and 230% for Seagate.
The Secret Behind the Software-Like Economics
The driver behind these dream-like margins is in how Sandisk sells. Rather than relying on the notoriously volatile spot market for memory, where prices swing wildly with supply and demand, the company has been locking its biggest customers into multi-year, largely fixed-price contracts.
These agreements have transformed the business. Sandisk now has tens of billions of dollars in minimum contracted revenue stretching years ahead, covering a large slice of its expected output. That gives it something the memory industry has often sought but rarely received: predictable, annuity-like revenue that behaves more like a software subscription than a one-time sale.
Underpinning it all is the voracious appetite for storage created by the artificial intelligence (AI) boom. Demand for memory continues to outstrip supply, and this imbalance is expected to persist, handing Sandisk the pricing power to sign these lucrative deals in the first place.
Wall Street Is Taking Notice
That transformation has not been lost on the analyst community. Argus recently upgraded its rating on Sandisk to a Buy, slapping a hefty $1,600 price target on the stock after the recent bout of profit-taking left the shares looking heavily oversold.
The team there pointed to accelerating demand, the company's leadership in NAND flash memory, and its push deeper into the lucrative data center market as reasons to expect those enviable margins to keep expanding.
Why the Bears Are Not Buying It
For all the excitement, some still urge caution. The most pointed concern is that those same fixed-price contracts, so prized for their visibility, may also cap how much higher margins can climb. Indeed, the company's own guidance for the current quarter implies margins holding steady or even ticking down slightly from their recent peak.
A second worry centers on how Sandisk got there. The bears note that much of the surge came from rising prices rather than shipping vastly more product, and price-led booms tend to fade once the shortage eases. Demonstrating durable growth in actual volumes, they argue, is the real test of whether these margins can endure.
Where the Real Test Lies
So which side has it right? Both bulls and bears are looking at the same eye-watering numbers and drawing opposite conclusions about what they mean for the stock. It’s easy to get excited about the bulls’ argument and lean into the real structural shift taking place, with contracted revenue and AI-driven demand turning a cyclical business into something steadier. However, the bears’ view that this is a price-driven spike destined to fade is hard to ignore.
The share price reflects that uncertainty. While Sandisk shares are up over 540% so far this year, the ride has been anything but smooth, including a fall of more than 50% during an industry-wide sell-off in July before a rebound of almost 40% in the past fortnight.
In many ways, that kind of volatility is to be expected for a stock whose future is so hotly contested, and anyone thinking about getting involved needs to be ready for more periods like it.
