Entegris Stock Hits Buy Point Following Upbeat Earnings Report

By Patrick Seitz, Investor’s Business Daily, February 6, 2019

Semiconductor equipment supplier Entegris (ENTG) saw its shares reach a buy point on Wednesday, a day after the company posted better-than-expected quarterly results. Entegris stock has been consolidating for 34 weeks.

On the stock market today, Entegris stock rose 2.2% to 34.05. Earlier in the session, it crossed a buy point of 34.38 out of a cup-with-handle base. It climbed as high as 34.48 before retreating. Trading volume was above average.

On Tuesday, the Billerica, Mass.-based company reported fourth-quarter results. It earned an adjusted 47 cents a share on sales of $401.6 million in the December quarter. Analysts expected Entegris to earn 46 cents on sales of $396 million.

On a year-over-year basis, earnings rose 12% and sales climbed 15% in the fourth quarter.

For the current quarter, Entegris said it expects sales and adjusted earnings per share to be about the same as in the fourth quarter. In the year-earlier March quarter, Entegris earned 47 cents a share on sales of $367 million.

Entegris Touts Unmatched Breadth Of Capabilities

Entegris is a leader in specialty chemicals and advanced material systems for the microelectronics industry. Its customers include chipmakers like Samsung and Taiwan Semiconductor Manufacturing (TSM) as well as chip equipment makers.

Entegris has three business units: specialty chemicals and engineered materials, microcontamination control systems, and advanced materials handling systems.

“We are the only company in the world that has that breadth of capabilities,” Chief Executive Bertrand Loy told Investor’s Business Daily. “What that means for the customers is that we can develop comprehensive solutions faster than any one of our competitors.”

Versum Materials Acquisition To Provide Scale

Last week, Entegris announced its plan to buy Versum Materials (VSM) in an all-stock deal worth about $4 billion. The transaction will combine two chemical companies that supply critical components for the semiconductor industry.

The deal is structured as a merger of equals. Holders of Entegris stock will own 52.5% of the combined company, while Versum shareholders will own 47.5%.

While chip and chip-equipment industries have consolidated, chemical and materials suppliers to the semiconductor field remain fragmented, Loy said.

“That’s a problem because it is getting more expensive to develop the next generation of process technology,” Loy said. “Our customers are expecting their suppliers to increase the level of R&D spending. They’re expecting us to make bigger commitments to continue to invest in better labs next to their fabs. You cannot do that as a subscale company.”

The addition of Versum will give Entegris the financial means to make the expected investments in research and development and manufacturing capabilities, he said.

“Scale matters in this industry,” Loy said.
