Donaldson versus Tetra Tech: What Investors Need to Know

The Zacks Categorized Pollution Control industry’s rank has trended up sharply in the past week. Currently, it holds a Zacks Industry Rank of 101 (among more than 256 industries) which is a massive improvement over the 200th rank it held last week. Two leading companies operating within the sector, Donaldson Company, Inc. DCI and Tetra Tech, Inc. TTEK have caught our attention today. Read on for a comparative analysis to find out which of them offers a more attractive proposition for investors right now.

Starting with recent share price performance, Donaldson has charted an impressive growth trajectory over the past six months, gaining 22.6%. In contrast, Tetra Tech has returned only half that. To put things in perspective, while Donaldson strongly outperformed the Zacks Categorized Pollution Control Equipment and Services industry average return of 9.7% over the same time frame, Tetra Tech barely managed to graze it at a return of 11.2%.

The Growth Drivers

Delving into the growth drivers, Donaldson has been benefitting of late from stabilization in its end markets. Positive effects of restocking, favorable commodity prices, decent rig counts and stable industrial production are some of the tailwinds for its growth. Restocking has been helping in the Original Equipment business and growing rig count is proving conducive to independent channel business. Based on these positive trends, the company raised both its top and bottom-line guidance for fiscal 2017, concurrent with the fiscal second-quarter 2017 results.

Donaldson now expects year-over-year fiscal 2017 sales growth in the band of 2–4%, as against the previously guided range of a 2% decline to a 2% increase. In terms of segments, Donaldson estimates Engine Products sales rise of 5–7% year over year, on the back of robust performance of Aftermarket, Off-Road, and Aerospace and Defense end markets. We are highly optimistic about Donaldson’s growth prospects in light of these positive trends.

Tetra Tech has several growth drivers in place as well. The company’s focus on high-end consulting and engineering services continues to boost its high value and high margin businesses. For fiscal 2017, Tetra Tech remains bullish about its growth across all four client sectors namely, U.S. federal, U.S. state and local, the U.S. commercial work, and finally, international. The company’s U.S. state and local clients—in both the municipal water and smart water services domains—are expected to be its strongest growth drivers for the upcoming quarters.
