Axcelis Technologies vs. AXT Inc.: Which Semiconductor Stock is a Better Investment?

NASDAQ: ACLS | Axcelis Technologies, Inc. News, Ratings, and Charts

ACLS – Increasing government and corporate investments to address the global semiconductor chip shortage, and rising demand from several industries, should continue driving the semiconductor industry’s growth. Therefore, we think lesser-known players in this space, Axcelis (ACLS) and AXT (AXTI), should benefit. But which of these stocks is a better buy now? Let’s find out.

Axcelis Technologies, Inc. (ACLS) in Beverly, Mass., and Fremont, Calif.-based AXT, Inc. (AXTI) are two lesser-known players in the semiconductor industry. With a market capitalization of $1.67 billion, ACLS designs, manufactures, and services ion implantation and other processing equipment used to fabricate semiconductor chips globally. In comparison,  AXTI manufactures and distributes compound and single-element semiconductor substrates using its proprietary vertical gradient freeze technology. It has a market capitalization of $416.57 million. Both companies sell their products through direct sales channels internationally.

Amid a global semiconductor chip shortage, rising demand from several industries, including automotive and consumer electronics, has increased chip prices. Furthermore,  in the second quarter of 2021, worldwide semiconductor sales increased 29.2% year-over-year. To address the problems caused by the shortage, governments and corporates worldwide are investing to boost semiconductor production. And the U.S. Senate has passed a landmark bill that includes $52 billion in planned spending to increase domestic production of semiconductors.

The global semiconductor market is expected to grow 25.1% to  $551 billion in 2021. Given the favorable industry backdrop and the prevailing low-interest-rate environment, small-cap stocks ACLS and AXTI should benefit.

While AXTI’s shares have lost 32.5% in price over the past six months, ACLS has surged 22.3%. ACLS is a clear winner with 26% price gains versus AXTI’s negative returns in terms of their past month’s performance. But which of these stocks is a better pick now? Let’s find out.

Latest Developments

On July 21, 2021, ACLS announced the first shipment of its  Purion EXE Power Series SiC high energy system to a new customer in China. ACLS is looking forward to offering new and innovative implant solutions to chipmakers by serving the rapidly growing power device market segment with its Purion Power Series platform’s common and flexible architecture, coupled with its uniquely differentiated silicon carbide process capabilities.

In an announcement on  April 28, AXTI said it had developed and shipped its first 8-inch diameter gallium arsenide (GaAs) substrates to a major customer. The material quality, scalability, and low defect rates of these wafers demonstrate AXTI’s commitment to excellence and the differentiation of its VGF crystal growth process. AXT has received significant interest from several customers due to the development of high-volume applications and expected high demand for 8-inch GaAs wafers in the coming months.

POWR Ratings

While AXTI has an overall D grade, which translates to Sell in our proprietary POWR Ratings system, ACLS has an overall B grade, equating to Buy. The POWR Ratings are calculated considering 118 different factors, each weighted to an optimal degree.

ACLS has a B grade for Value, which is consistent with its lower-than-industry valuation ratios. ACLS’ 14.03x forward EV/EBIT is 31.8% lower than the 20.58x industry average. However, AXTI’s C grade for Value reflects its relatively higher valuation compared to its peers. The company has a 23.37x forward EV/EBIT, which is 13.6% higher than the 1.91x industry average.

In terms of Quality, ACLS has been graded a B, in sync with its higher-than-industry profitability ratios. ACLS has an 11.9% trailing-12-month net income margin, which is 97.6% higher than the 6% industry average. However, AXTI’s F grade for Quality is in sync with its negative trailing-12-month levered free cash flow margin.

Of the 99 stocks in the B-rated Semiconductor & Wireless Chip industry, AXTI is ranked #86, while ACLS is ranked #16.
