Most Popular Narrative: 14.6% Undervalued
At a last close of $83.87 versus a narrative fair value of $98.20, the current price sits below what this widely followed framework implies.
Global expansion of environmental regulations and emissions standards is increasing demand for advanced filtration across industrial and transportation sectors, positioning Donaldson to achieve record sales in both Industrial Solutions and Mobile Solutions, with a direct positive impact on revenue and earnings growth in FY26 and beyond. Industrial automation and digitalization are driving higher requirements for contaminant free environments, fueling double digit growth in Donaldson's connected and aftermarket filtration solutions, improving the recurring revenue base and operating margins.
Curious what earnings power sits behind that valuation gap? The narrative leans on steady revenue compounding, higher margins and a future earnings multiple that asks investors to think long term.
Based on this framework, the analysis discounts those future cash flows at 8.38%, arriving at an implied fair value of $98.20 per share, above today’s price but still within a range shaped by execution and end market assumptions. The result reflects a view that current earnings, margins and reinvestment can support a higher value than the market is currently assigning, while still using a cost of capital that aligns with a mature industrial business.
Result: Fair Value of $98.20 (UNDERVALUED)

However, investors also need to weigh slower bioprocessing momentum and Donaldson's reliance on traditional engine related filtration, which could challenge the long term growth story.

Another way to look at Donaldson’s valuation
The first framework relies on discounted future cash flows, but the current P/E of 25.7x tells a more cautious story. It is slightly cheaper than the US Machinery industry at 26.5x, yet richer than peers at 24.7x and above a fair ratio of 24.3x. That premium suggests investors are already paying up, so consider how much conviction you need in the growth and margin narrative for that to feel comfortable.
