• On Simply Wall St's value checks, Avantor scores 5 out of 6. This sets up a closer look at how different valuation methods line up for the stock and how a deeper framework later in this article can help you judge whether that score fits your own view.

Approach 1: Avantor Discounted Cash Flow (DCF) Analysis

A Discounted Cash Flow, or DCF, model estimates what a business could be worth by projecting its future cash flows and then discounting those back to today using a required rate of return. It focuses on the cash the company is expected to generate for shareholders rather than near term earnings.

For Avantor, the model used is a 2 Stage Free Cash Flow to Equity approach based on cash flow projections. The latest twelve month Free Cash Flow is about $487 million. Analysts provide several years of Free Cash Flow estimates, and Simply Wall St then extends these projections further. For example, the model includes a ten year path where projected Free Cash Flow reaches $887.9 million in 2035, with discounted values for each year.

Bringing all those future cash flows back to today, the DCF output suggests an intrinsic value of about US$15.67 per share. Against the recent share price of US$7.86, this implies the stock is 49.8% undervalued based on these assumptions and inputs.

Result: UNDERVALUED

Approach 2: Avantor Price vs Sales

For companies where revenue is a key anchor and earnings can be less consistent, the P/S ratio is often a useful yardstick because it compares what investors pay to the sales the business generates. The higher the growth investors expect and the lower they perceive the risk, the higher the P/S ratio they are usually prepared to accept as “normal” for a stock.

Avantor currently trades on a P/S ratio of 0.81x. That is below the Life Sciences industry average P/S of 3.26x and also below the peer group average of 4.17x. Simply Wall St’s Fair Ratio for Avantor is 2.48x, which is a proprietary estimate of what the P/S might be given factors such as earnings growth, industry, profit margin, company size and risk profile.

This Fair Ratio can be more informative than a simple comparison with peers or the industry because it adjusts for Avantor’s own mix of growth, risks, margins, industry and market capitalization. Comparing the Fair Ratio of 2.48x with the current P/S of 0.81x suggests the shares trade at a discount on this measure.

Result: UNDERVALUED

Upgrade Your Decision Making: Choose your Avantor Narrative

Earlier the article mentioned that there is an even better way to understand valuation, so here is Narratives. This is where you set out a clear story for Avantor, link that story to specific forecasts for revenue, earnings and margins, and then see the fair value that falls out of those assumptions.

On Simply Wall St’s Community page, Narratives are an easy tool that lets you connect what you believe about Avantor’s business, such as a turnaround in Lab Solutions or lasting margin pressure, to a full financial model and a fair value estimate that you can compare directly with the current share price to help decide whether the stock looks cheap or expensive to you.

Because Narratives update automatically when new earnings, news or analyst targets are added, you can see how different viewpoints play out in real time. For example, you can compare a more optimistic fair value near US$19.00 with a cautious view closer to US$7.00, then choose which version of Avantor’s future you think is more realistic and how that lines up with today’s price.
