Avantor (AVTR) Stock Looks Fairly Valued After a 56% Five Year Fall

Avantor has bounced hard this year, yet over a 5 year stretch long term holders have seen a very different story. That split performance raises a direct question for anyone looking at the stock today, which is whether the current share price sits on solid ground when you look at the cash the business is expected to generate.

• The share price has fallen 56.3% over 5 years, which puts the focus firmly on whether the cash flow outlook now lines up with the recovery in sentiment.
• The business model leans on recurring demand for lab supplies and services, which can support relatively steady cash generation if customers keep spending through different industry cycles.

The issue now is whether Avantor's recent share price level is justified by what its cash flows suggest the stock is intrinsically worth.

If you want to sanity check Avantor against other opportunities where pricing is also anchored on cash generation, it can help to line it up beside 29 high quality undervalued stocks.

Where Does Avantor Sit on Cash Flow?

The Discounted Cash Flow (DCF) model here focuses on the cash Avantor can return to shareholders over time, adjusted back to today’s dollars. Avantor generated about $454.0 million of free cash flow over the last twelve months, which gives the starting point for the calculation. Analyst projections then step that up to higher levels by 2030, with the later years easing into slower, more measured growth rather than sharp swings.

Those expectations describe a business that the model treats as growing, with relatively steady free cash flow rather than highly volatile swings. On that basis, the DCF outcome suggests Avantor’s estimated intrinsic value is broadly in line with the current share price of $17.29, so the recent recovery leaves less obvious mispricing on the cash flow numbers alone.
