As the demand for artificial intelligence computing power accelerates, investors are comparing the digital infrastructure of Applied Digital (APLD -4.13%) against the specialized hardware offerings of Super Micro Computer (SMCI -3.30%). Which stock is the better buy?
Applied Digital focuses on building and operating the large-scale data centers required for advanced computing workloads, while Super Micro Computer designs the high-end server racks that power them. Both companies are central to the AI revolution but face distinct operational and financial hurdles as the industry matures.
The case for Applied Digital
Applied Digital builds and operates high-performance computing data centers that provide the physical foundation for artificial intelligence and machine learning applications. The company primarily generates revenue through long-term hosting leases with major customers such as CoreWeave and other investment-grade hyperscalers. Customer concentration like this adds a layer of risk to the business, as a significant portion of future growth relies on a handful of key relationships. To meet rising demand, the company is expanding its capacity through massive projects like Polaris Forge and Delta Forge in North America.
In its 2026 fiscal year (FY), ended May 31, revenue reached $611.3 million, representing an increase of 167% compared to the prior year. Despite this rapid top-line expansion, the company reported a net loss attributable to common stockholders of $249.2 million for its continuing operations. This resulted in a negative net margin of 40.8%, illustrating that the company is currently prioritizing rapid infrastructure scaling over immediate profitability. This aggressive growth strategy requires constant investment in capital-intensive data center facilities.
As of its May 2026 balance sheet, the current ratio is 4.0x, which measures a company's ability to pay short-term debts with short-term assets. The debt-to-equity ratio reached 2.9x, indicating that total liabilities exceed shareholder equity. Free cash flow, the cash remaining after paying for operations and capital expenses, was negative $2.8 billion during this period. Note that stock-based compensation represented 245.5% of operating cash flow, meaning reported cash generation is heavily inflated by this non-cash add-back. This is a common characteristic among semiconductor stocks and related infrastructure providers during high-growth phases.
The case for Super Micro Computer
Super Micro Computer designs and sells application-optimized IT solutions, including liquid-cooled server racks and rack-scale systems for enterprise and cloud providers. The company has a significant global footprint with manufacturing campuses in Asia and Europe, allowing it to serve a diverse set of internet data centers and 5G infrastructure markets. Revenue is concentrated among a limited group of large customers, with four accounts each representing more than 10% of total net sales in recent periods. This dependency means that the loss of a single major partner could significantly impact overall results.
In FY 2026, which ended June 30, revenue reached $39.1 billion, which is a growth of 77.8% over the previous fiscal year. Unlike many high-growth infrastructure peers, the company is profitable, reporting net income of $2.2 billion for the same period. This led to a net margin of 5.7%, showing that Super Micro Computer can generate consistent earnings while scaling its server production. The company continues to benefit from the cyclical demand for high-end computing solutions across the tech sector.
As of its June 2026 balance sheet, the current ratio is 3.9x, suggesting a healthy cushion for meeting short-term obligations. The debt-to-equity ratio is 0.6x, indicating a more conservative capital structure compared to many smaller infrastructure plays. Free cash flow was negative $7.0 billion for the fiscal year, largely due to the high costs of inventory and equipment needed to meet surging AI demand. While the company is profitable on a net income basis, its cash consumption remains high as it builds out global manufacturing capacity.

Key Financial Metrics
Risk profile comparison
Applied Digital faces significant risks related to its high customer concentration and its need for substantial additional capital to finish ongoing data center projects. The company carries a heavy debt load and relies on third-party power suppliers, which can lead to operational delays or increased costs if energy prices fluctuate. There are also potential conflicts of interest regarding its relationships with certain affiliates and risks associated with its recent ChronoScale cloud business separation. These factors make the company's path to consistent profitability dependent on both execution and favorable market conditions.
Super Micro Computer deals with legal and regulatory challenges, including multiple class action lawsuits and past issues regarding internal control over financial reporting. The company relies on a limited number of suppliers for critical components like GPUs, putting it at the mercy of industry giants like NVIDIA and Intel. Geopolitical tensions and trade control restrictions also pose threats to its global manufacturing and sales operations. Furthermore, the server market is intensely competitive, and any shift in the cyclical demand for AI computing could cause volatility in its operating results.
Valuation comparison
Super Micro Computer stock appears significantly cheaper, while Applied Digital trades at a premium reflecting its specialized niche and faster revenue growth rate.

Which stock would I buy in 2026?
Investors looking at Applied Digital and Super Micro Computer stocks to gain exposure to the artificial intelligence market have a tough choice. Both are experiencing strong revenue growth thanks to the AI tailwind.
However, Applied Digital has amassed over $5 billion in debt at the end of its FY 2026 as it tries to quickly build out more data centers. It is a landlord to AI hyperscalers, and cannot collect rent until these facilities are built. To its credit, it has secured lease agreements worth $36 billion over the next 15 years. So if it can complete the new data centers, the company can count on predictable revenue for years to come.
Super Micro Computer has been plagued by controversies in recent years. Last year, the company's stock was almost delisted for failing to file required earnings reports on time. This year, one of its founders, who no longer works for Super Micro, was charged with attempting to smuggle servers to China in violation of U.S. export laws.
If you can overlook the controversies, Super Micro Computer is the better stock to own. Not only are its sales soaring, it is a profitable company, unlike Applied Digital. For fiscal year 2027, Super Micro forecasted sales in the range of $65 billion to $72 billion, an impressive increase from the prior year's $39.1 billion.
