Approach 1: Teradyne Discounted Cash Flow (DCF) Analysis

A Discounted Cash Flow model takes projected future cash flows and discounts them back to today using a required rate of return to estimate what the business might be worth right now.

For Teradyne, the latest twelve month Free Cash Flow is about $533 million. Analysts supply Free Cash Flow estimates for the next few years, and Simply Wall St extends those using a 2 Stage Free Cash Flow to Equity model, with projections reaching a Free Cash Flow figure of $2.29b in 2030. All of these are assessed in dollar terms, even if accounting and listing currencies differ.

Using these projections, the DCF model arrives at an estimated intrinsic value of about $197.44 per share, compared with the current share price of $345.42. On this basis, the model implies the stock is around 75.0% overvalued, which suggests expectations in the market are ahead of what this cash flow forecast supports.

Result: OVERVALUED

Our Discounted Cash Flow (DCF) analysis suggests Teradyne may be overvalued by 75.0%. Discover 51 high quality undervalued stocks or create your own screener to find better value opportunities.

Approach 2: Teradyne Price vs Earnings

For profitable companies, the P/E ratio is a useful shorthand for what you are paying today for each dollar of earnings. It lets you compare how the market prices different businesses that already generate profits, rather than relying on sales or assets alone.

What counts as a “normal” P/E partly reflects how quickly earnings are expected to grow and how risky those earnings appear. Higher expected growth or lower perceived risk can justify a higher P/E, while slower growth or higher risk usually lines up with a lower multiple.

Teradyne currently trades on a P/E of 63.32x. That sits above the Semiconductor industry average of about 48.19x and above the peer average of 57.32x. Simply Wall St’s proprietary Fair Ratio for Teradyne is 50.47x, which is the P/E level it estimates based on factors such as earnings growth, industry, profit margin, market cap and company specific risks.

This Fair Ratio aims to improve on simple peer or industry comparisons by tailoring the “expected” P/E to Teradyne’s own profile instead of assuming it should match the group. Comparing the current 63.32x P/E with the 50.47x Fair Ratio suggests the shares are priced richer than that model would indicate.

Result: OVERVALUED

Upgrade Your Decision Making: Choose your Teradyne Narrative

Earlier it was mentioned that there is an even better way to understand valuation, so this is where Narratives come in, giving you a short story about Teradyne that sits behind the numbers you see for fair value, future revenue, earnings and margins, and linking that story directly to a forecast and a fair value estimate.

On Simply Wall St’s Community page, Narratives are available as an easy tool used by millions of investors. You can see different Teradyne stories side by side and how each one translates into a modeled fair value that you can compare with the current US$345.42 share price when thinking about buy or sell decisions.

For Teradyne, one investor might lean toward the higher fair value around US$415.00, built on assumptions such as faster revenue growth and higher profit margins tied to AI data center test demand and robotics. Another might anchor on a lower fair value near US$74.00 that reflects concerns about competition, cyclicality and lower assumed P/E multiples.

As news, earnings and guidance arrive, those Narratives and their underlying assumptions are updated. This means the fair values and storylines you see stay aligned with the latest information rather than a one off snapshot that goes stale.

For Teradyne however we will make it really easy for you with previews of two leading Teradyne Narratives:

Fair value in this bullish narrative: US$415.00 per share.

Implied discount to this fair value at US$345.42: about 16.8% undervalued.

Assumed future revenue growth: 31.51% a year.

• Assumes AI data center test and high bandwidth memory demand support higher sales and margins across Teradyne's core test platforms.
• Builds in a mix of semiconductor and robotics revenue, supported by product development, partnerships and a US$1b buyback through 2026.
• Values the stock at a future P/E of 37.5x on projected 2029 earnings, with fair value at US$415.00 subject to the growth and margin profile playing out as outlined.

Fair value in this more conservative narrative: US$307.41 per share.

Implied premium to this fair value at US$345.42: about 12.4% overvalued.

Assumed future revenue growth: 22.73% a year.

• Works off analysts expecting solid but lower revenue growth and margin expansion than the bullish case, with earnings reaching about US$952.0m by 2028.
• Factors in benefits from AI, robotics and automation, along with the Quantifi Photonics acquisition and buybacks, but balances these with tariff and demand uncertainty.
• Applies a lower future P/E of 24.0x to those earnings and arrives at a fair value of about US$307.41, which sits below the current US$345.42 share price.

Both narratives use the same company, the same current share price and many of the same data points, but show how different assumptions about growth, margins, risks and future P/E can lead to very different fair value ranges. The key step for you is to decide which story, if either, lines up more closely with your own expectations for Teradyne over the next few years.
