Approach 1: Lam Research Discounted Cash Flow (DCF) Analysis

A Discounted Cash Flow, or DCF, model estimates what a company might be worth today by projecting its future cash flows and then discounting those back to a present value.

For Lam Research, the model uses a 2 Stage Free Cash Flow to Equity approach. It starts from last twelve months free cash flow of about US$6.40b. Analysts supply forecasts for several years, and then Simply Wall St extends these out, with projected free cash flow of US$11.69b in 2030. Intermediate annual projections between 2026 and 2035 are also included and range in the multi billion dollar level, with each year discounted back to reflect risk and the time value of money.

When all these discounted cash flows are added together, the DCF model arrives at an estimated intrinsic value of US$115.13 per share. Against the recent share price of US$233.31, this implies the stock is about 103% above the DCF estimate, so the model suggests Lam Research is overvalued on this cash flow basis.

Result: OVERVALUED

Approach 2: Lam Research Price vs Earnings

For a profitable company, the P/E ratio is a straightforward way to connect what you pay for each share with the earnings that support that price. It helps you see how many dollars investors are willing to pay today for one dollar of current earnings.

What counts as a "normal" P/E depends on how the market views a company’s growth potential and risk. Higher expected growth or lower perceived risk can support a higher P/E, while lower growth or higher risk tends to point toward a lower multiple.

Lam Research currently trades on a P/E of 46.89x. That sits above the broader Semiconductor industry average of 40.05x, but below the peer group average of 50.20x. Simply Wall St’s Fair Ratio for Lam Research is 45.88x, which is its own estimate of an appropriate P/E given factors such as earnings growth, profit margins, industry, market cap and specific risks.

This Fair Ratio goes further than a simple comparison with peers or the industry because it ties the expected multiple more closely to Lam Research’s own characteristics instead of broad group averages.

With the actual P/E of 46.89x sitting slightly above the Fair Ratio of 45.88x, the stock screens as mildly overvalued on this metric.

Result: OVERVALUED

Upgrade Your Decision Making: Choose your Lam Research Narrative

Earlier it was mentioned that there is an even better way to understand valuation, so this is where Narratives come in, letting you attach a clear story about Lam Research to the numbers, connect that story to a forecast for revenue, earnings and margins, and then compare the resulting Fair Value with the current share price of US$233.31 in a simple, visual way on the Narratives section of the Simply Wall St Community page.

Each Narrative is a short, structured view of what you think the next few years look like. The platform then turns that view into a Fair Value range that updates automatically when fresh information arrives, such as Lam Research’s guidance for Q3 2026 revenue of US$5.4b to US$6.0b and non GAAP EPS of US$1.35, or new commentary around wafer fab equipment spending and AI related demand.

For Lam Research specifically, one investor might choose a more cautious Narrative that aligns with a Fair Value near US$115, focusing on export controls, China exposure and margin pressure. Another might pick a more optimistic Narrative closer to US$325 that leans on AI data center buildouts, DRAM and NAND spending and higher assumed margins. Comparing either Narrative Fair Value with the current price helps you decide whether the stock looks expensive, cheap or roughly in line with your own expectations.

For Lam Research, here are previews of two leading Lam Research Narratives to help frame the analysis:

Fair value in this bullish Narrative is about US$274.90 per share.

On that basis, the current price of US$233.31 sits roughly 15.1% below the Narrative fair value estimate.

Revenue growth in this scenario uses an annual rate of about 16.49%.

• Assumes AI related chip demand, new fab incentives and Lam's process tools keep the order book strong and broaden the customer base.
• Builds in solid earnings and margin support from advanced etch and deposition tools, higher value content per wafer and more recurring service revenue.
• Accepts risks around geopolitics, customer concentration and competition, but still concludes the stock could justify a higher valuation if these catalysts play out.

Fair value in this bearish Narrative is about US$115.00 per share.

With the current price at US$233.31, that view implies the stock sits around 102.9% above the Narrative fair value estimate.

Revenue growth in this scenario uses an annual rate of about 7.58%.

• Focuses on export controls, heavy China exposure and rising local competition as potential headwinds for Lam's orders and pricing.
• Builds in pressure from higher R&D and compliance costs, which could weigh on margins and free cash flow over time.
• Assumes lower revenue growth and a more modest P/E multiple, which together point to a substantially lower fair value than the current share price.

Both previews provide a clear starting point. The key step now is deciding which set of assumptions aligns more closely with your view of Lam Research's growth, risks and fair value.
