Is Twist Bioscience (TWST) Too Rich Or Still Reasonable On Sales?
Share
Listen to the news

Twist Bioscience has seen its share price move sharply over recent years, which puts a spotlight on a simple question for you as an investor. Is the current valuation of the stock supported by the sales the business is generating today and what the market expects those revenues to become?

  • Over the past 3 years, Twist Bioscience has delivered a very large share price gain of around 7x. This raises the stakes on whether the underlying sales justify that kind of move.
  • The company is highlighted as a key player in the growing biofoundry-as-a-service market. This can shape how investors think about its potential revenue trajectory and the price placed on each dollar of sales.
  • Your read on Twist Bioscience is one view; the desks covering it have another. See what analysts think Twist Bioscience's shares could be worth.

The issue now is whether the stock price around US$139.77 is aligned with the company’s sales when judged against a Fair Ratio benchmark.

Does Twist Bioscience Look Pricey on Sales?

P/S fits Twist Bioscience because the business is still loss making and investors are effectively paying for revenue and the promise of future cash flows rather than current profits.

On this lens, the stock trades on a P/S ratio of about 20.3x, which is much higher than the Biotechs industry average of roughly 10.8x and also above the peer group around 12.8x. The Fair Ratio, which reflects what might be paid for each dollar of sales given Twist Bioscience’s growth profile, profitability path, size and risk, sits below the current P/S so the shares screen overvalued on this framework. Because the biofoundry as a service market is being highlighted for rapid expansion and AI automation, the current premium P/S suggests investors are already paying up heavily for that story.

For you as a shareholder or potential buyer, that gap between the present 20.3x sales multiple and the benchmark raises the bar for how much future revenue quality and scale Twist Bioscience needs to deliver for the share price to look justified on this single metric.
