ARM vs LRCX: key metrics side by side

Full side-by-side comparison of ARM and LRCX across valuation, profitability, growth and analyst sentiment. Data updated 2026-04-01.

ARM vs LRCX valuation comparison

A direct ARM vs LRCX valuation comparison for 2026 reveals a significant divergence, particularly in price-to-earnings (P/E) ratios. ARM trades at a P/E of 200.57x, which is exceptionally high and suggests strong market expectations for future growth, or that the stock may be considerably overvalued at its current price of $151.28. In contrast, LRCX presents a much more appealing P/E ratio of 43.32x, which, while still elevated, is substantially lower than ARM’s and indicates a more reasonable valuation for its current earnings, especially given its position in the semiconductor equipment industry. This makes LRCX appear considerably cheaper on an earnings multiple basis.

Further examining the ARM vs LRCX valuation, the Discounted Cash Flow (DCF) models indicate that both stocks may be trading above their intrinsic value, but LRCX shows less severe overvaluation. ARM’s DCF suggests a potential downside of -95.5%, valuing the company at just $6.88 compared to its current price. LRCX’s DCF also indicates a negative upside of -76.3%, implying an intrinsic value of $50.62. While both DCF figures signal caution, LRCX’s valuation gap is less extreme. On a price-to-book (P/B) basis, ARM has a P/B of 20.6x, which is lower than LRCX’s 26.53x, suggesting ARM’s assets are valued slightly less by the market per share, though both are quite high. Overall, when considering the P/E and DCF metrics, LRCX emerges as the more attractively valued stock in this ARM vs LRCX fundamentals and valuation analysis.

ARM vs LRCX growth comparison

In the ARM vs LRCX growth comparison, both companies exhibit robust year-over-year revenue growth figures, highlighting the dynamic nature of the technology sector they operate within. ARM has reported a revenue growth of +23.9%, marginally outpacing LRCX’s +23.7%. This slight edge indicates strong momentum for ARM, which is at the forefront of semiconductor intellectual property design, benefiting from the expanding demand for AI-driven chips and other advanced computing architectures. Despite its smaller revenue base of $4.01 billion compared to LRCX’s $18.44 billion, ARM’s percentage growth rate underscores its rapidly expanding market footprint.

LRCX, with its substantial revenue base and comparable growth rate, demonstrates impressive scale and operational efficiency in the highly competitive semiconductor manufacturing equipment industry. A 23.7% revenue growth on an $18.44 billion base represents a significant absolute increase in sales. While ARM’s growth is slightly higher in percentage terms, LRCX’s larger scale suggests a formidable ability to capture market share and execute on large-scale projects. Both companies benefit from secular tailwinds in semiconductors, but ARM’s niche in IP licensing provides a slightly different growth vector than LRCX’s capital equipment sales. Looking at future estimates, both are expected to continue benefiting from high demand in the technology sector, with ARM’s slightly higher percentage growth suggesting a stronger momentum in its specific market segment.

ARM vs LRCX profitability

When comparing ARM vs LRCX profitability, Lam Research Corporation (LRCX) clearly demonstrates superior efficiency in turning revenue into profit. LRCX boasts a net profit margin of 30.22%, significantly outperforming ARM’s 17.15%. This suggests that for every dollar of revenue, LRCX retains nearly twice as much as profit after all expenses, including taxes, are accounted for. This robust net margin for LRCX is further supported by an EBITDA margin of 36.48%, which is also considerably higher than ARM’s 22.41%. These figures highlight LRCX’s operational leverage and cost management effectiveness within the complex semiconductor equipment manufacturing landscape.

Moving to cash generation, LRCX also leads in Free Cash Flow (FCF) yield. LRCX offers an FCF yield of 2.5%, indicating a healthier ability to generate cash from its operations after accounting for capital expenditures. ARM’s FCF yield stands at a much lower 0.6%, suggesting that despite its growth, it is currently converting less of its revenue into free cash that could be used for debt reduction, dividends, or share buybacks. Neither company provided a Return on Equity (ROE) figure, both being N/A%, which limits a complete picture of shareholder return efficiency. However, based on net margins, EBITDA margins, and FCF yield, LRCX unequivocally generates more cash and is the more profitable entity in this ARM vs LRCX stock comparison 2026.

Analyst ratings: ARM vs LRCX

The analyst community holds a generally positive outlook for both ARM and LRCX, with both stocks carrying a “Buy” consensus rating. ARM is covered by 27 analysts, with a compelling 77.8% recommending a “Buy.” This high percentage indicates strong confidence in ARM’s long-term prospects, particularly given its crucial role in chip design innovation for various growing markets. However, the consensus price target for ARM is $156.25, suggesting a modest upside of just +3.3% from its current price of $151.28. This implies that much of its future potential might already be priced into the stock, or analysts are exercising caution given its already high valuation multiples.

LRCX, on the other hand, is covered by a larger pool of 50 analysts, with 76.0% issuing a “Buy” recommendation. While slightly lower than ARM’s percentage, it still represents a strong positive sentiment. What truly sets LRCX apart is the significant upside projected by these analysts. The consensus price target for LRCX stands at $275.76, which represents an impressive +29.1% upside from its current price of $213.66. This suggests that analysts see considerably more room for appreciation in LRCX’s stock value compared to ARM. Therefore, while both are rated “Buy,” analysts see a much more substantial return potential from LRCX, making it the preferred choice for potential capital appreciation based on expert projections.

Should I buy ARM or LRCX stock in 2026?

Deciding whether to buy ARM or LRCX stock in 2026 depends heavily on an investor’s specific objectives and risk tolerance, as both companies offer distinct profiles within the technology sector. For growth-oriented investors, ARM might initially appear attractive due to its slightly higher revenue growth rate of 23.9% year-over-year compared to LRCX’s 23.7%. ARM’s position at the core of semiconductor design, particularly with the surging demand for AI and efficient computing, offers a compelling long-term narrative for continued expansion. However, its substantial valuation metrics, such as a P/E of 200.57x and a highly negative DCF upside, suggest that this growth potential may already be fully reflected, or even exceeded, in its current share price. Investors prioritizing pure growth must weigh this against the valuation risk.

For value investors, or those seeking a more balanced risk-reward proposition, LRCX appears to be the more compelling choice in this arm vs lrcx stock comparison 2026. With a P/E ratio of 43.32x, LRCX offers a significantly more palatable valuation multiple compared to ARM. While its DCF also indicates overvaluation, the projected downside of -76.3% is less severe than ARM’s -95.5%. Furthermore, LRCX demonstrates superior profitability with a net margin of 30.22% and a higher FCF yield of 2.5%, indicating a more efficient and cash-generative business model. These strong fundamentals, combined with a robust +29.1% analyst target upside, suggest LRCX could offer a better combination of growth and value.

Neither ARM nor LRCX are suitable for income investors seeking dividends, as both companies have a 0% dividend yield. Therefore, the decision should be purely based on capital appreciation potential and financial strength. Given the current arm vs lrcx fundamentals and valuation, LRCX presents a more attractive investment opportunity for those seeking a company with strong profitability, a substantial revenue base, and a more reasonable valuation with considerable analyst upside. This is not investment advice; always conduct thorough personal research and consider your financial situation before making investment decisions.
