ARM vs MU: key metrics side by side

Full side-by-side comparison of ARM and MU across valuation, profitability, growth and analyst sentiment. Data updated 2026-04-14.

ARM vs MU valuation comparison

When assessing ARM vs MU valuation, a stark contrast emerges. Arm Holdings plc trades at an exceptionally high P/E ratio of 213.3x and a P/B ratio of 21.91x. These figures suggest that ARM is priced for considerable future growth and innovation, reflecting its strategic position in the semiconductor design IP market. However, such elevated multiples indicate a premium valuation that could expose investors to significant risk if growth expectations are not met or if market sentiment shifts. The discounted cash flow (DCF) analysis for ARM further emphasizes this, indicating a substantial negative upside of -94.9%, suggesting the current market price is far above its intrinsic value based on this model.

In contrast, Micron Technology, Inc. presents a more grounded valuation. MU’s P/E ratio stands at 20.5x, which is significantly lower than ARM’s, positioning it as a potentially more attractive option for value-conscious investors within the technology sector. Its P/B ratio of 6.82x also points to a more reasonable pricing relative to its book value. The DCF model for MU, while still showing a negative upside of -85.9%, indicates a less severe overvaluation compared to ARM. This suggests that while both stocks appear overvalued by traditional DCF methods, MU offers a comparatively cheaper entry point and potentially a better risk-reward profile from a pure valuation perspective in this arm vs mu fundamentals and valuation comparison.

ARM vs MU growth comparison

The arm vs mu stock comparison 2026 reveals a clear leader in revenue growth momentum. Micron Technology, Inc. boasts an impressive year-over-year revenue growth of +48.9%, significantly outpacing Arm Holdings plc’s +23.9%. This robust growth for MU reflects strong demand for its memory and storage products, likely driven by advancements in AI, data centers, and other high-growth segments of the technology market. Micron’s substantial top-line expansion suggests strong underlying business momentum and market share gains in its cyclical industry.

While ARM’s 23.9% revenue growth is respectable, especially for a company with its market position in chip design, it does not match the accelerated pace seen at MU. ARM’s business model, focused on licensing intellectual property, typically boasts higher gross margins (95.43% for ARM vs 58.44% for MU), but MU’s overall revenue trajectory is currently stronger. When considering overall growth potential, both companies operate in dynamic and expanding markets. However, for investors prioritizing near-term revenue expansion and market momentum, MU exhibits stronger current growth indicators, translating into a more aggressive trajectory in this arm vs mu earnings growth comparison.

ARM vs MU profitability

Analyzing ARM vs MU profitability highlights different strengths and operational efficiencies within their respective business models. Micron Technology, Inc. demonstrates significantly higher net profitability, with a net margin of 41.49%, nearly two and a half times that of Arm Holdings plc’s 17.15%. This superior net margin for MU indicates excellent cost management and strong pricing power within its core memory and storage segments, allowing a larger portion of its revenue to translate into net income. Furthermore, MU’s EBITDA margin of 63.91% dwarfs ARM’s 22.41%, reinforcing Micron’s operational efficiency and ability to generate substantial earnings before interest, taxes, depreciation, and amortization.

In terms of cash generation, MU also holds a considerable advantage. Its Free Cash Flow (FCF) yield stands at 4.45%, demonstrating a strong ability to convert earnings into cash that can be used for reinvestment, debt reduction, or shareholder returns. ARM, in contrast, has a much lower FCF yield of 0.57%, suggesting its business model, while asset-light, generates less free cash relative to its market capitalization. Both companies report N/A% for Return on Equity (ROE), preventing a direct comparison on this specific metric. Overall, for investors prioritizing robust profitability and strong cash flow generation, Micron Technology, Inc. clearly generates more cash and exhibits superior margins in this arm vs mu profitability comparison.

Analyst ratings: ARM vs MU

When examining analyst ratings for ARM vs MU, both stocks receive a consensus ‘Buy’ recommendation, yet there are nuanced differences in the level of conviction and projected price targets. Arm Holdings plc is covered by 27 analysts, with 74.1% issuing a ‘Buy’ rating. The average analyst price target for ARM is $156.25, which implies a slight downside of -2.9% from its current price of $160.9717. This suggests that while analysts generally view ARM positively, they see its current valuation as largely reflecting its near-term potential, with limited immediate upside based on their models.

Micron Technology, Inc., with coverage from a larger pool of 68 analysts, has an even stronger consensus, with 80.9% recommending a ‘Buy’. The average analyst price target for MU is $428.65, indicating a marginal downside of -2.5% from its current price of $439.49. Although both stocks are trading slightly above their consensus price targets, MU’s higher percentage of ‘Buy’ ratings and slightly less negative implied downside suggests a stronger overall analyst preference. This broader and more confident backing from the analyst community indicates that MU is perceived as having a more favorable risk-reward balance or a more sustainable growth trajectory, making it the preferred choice among analysts in this arm vs mu analyst ratings and recommendations comparison.

Should I buy ARM or MU stock in 2026?

Deciding whether to buy ARM or MU stock in 2026 depends heavily on an investor’s specific objectives and risk tolerance. For growth investors, Micron Technology (MU) appears to offer a more compelling narrative. With its impressive 48.9% year-over-year revenue growth, significantly outperforming ARM’s 23.9%, MU demonstrates stronger current momentum in a cyclical yet resurgent memory and storage market, driven by AI and data center demand. While ARM has long-term potential due to its foundational role in chip design, MU’s immediate growth trajectory makes it the more attractive option for those prioritizing rapid top-line expansion in this arm vs mu stock comparison 2026.

From a value investment perspective, Micron Technology (MU) also stands out as the more appealing choice. Its P/E ratio of 20.5x and P/B ratio of 6.82x are substantially lower than ARM’s exorbitant P/E of 213.3x and P/B of 21.91x. While both stocks show negative DCF upsides, MU’s -85.9% is less extreme than ARM’s -94.9%, suggesting a comparatively more reasonable valuation relative to its intrinsic value. Investors seeking a balance of growth and a more palatable entry multiple in this arm vs mu fundamentals and valuation analysis would likely find MU a better fit.

For income-focused investors, neither ARM nor MU are suitable options, as both companies currently have a 0% dividend yield. Both are growth-oriented technology companies that prioritize reinvesting earnings back into the business for future expansion rather than distributing profits to shareholders via dividends. Therefore, if generating regular income from stock holdings is a primary goal, investors should look elsewhere. This is not investment advice; always conduct thorough due diligence before making investment decisions.
