Skyworks Solutions vs. Impinj: Which Internet of Things Stocks is a Better Buy?

The increasing integration of the Internet of Things (IoT) in everyday devices to facilitate lifestyle, working, and learning in the emerging 5G era should enable companies in this space to generate substantial growth. IoT stocks Skyworks (SWKS) and Impinj (PI) are cases in point. We think they should both benefit from the industry tailwinds. But let’s find out which of these stocks is a better buy now. Read on.

Skyworks Solutions, Inc. (SWKS) in Woburn, Mass., and Seattle, Wash.-based Impinj, Inc. (PI) are gaining popularity in the Internet of Things (IoT) space. SWKS is a wireless semiconductor company that designs and manufactures semiconductor products for radiofrequency and mobile communications applications. PI provides RAIN radio-frequency identification solutions for identifying, locating, and authenticating wirelessly connected items, and offers radio chips, gateways, readers and antennas, and software through its platform.

The demand for IoT-powered devices is on the rise across several industries. The continuing developments regarding keeping the data secure and enabling the devices to be monitored and controlled remotely and efficiently should fuel the IoT industry’s growth. Investor optimism about this industry’s growth prospects is evident in the  Global X Internet of Things Thematic ETF’s (SNSR) 35.4% returns over the past year versus the SPDR S&P 500 Trust ETF’s (SPY) 32.1% gains. The global IoT market is expected to grow at a 10.5% CAGR to $1.39 trillion by 2026. By contributing significantly to the IoT devices market, both SWKS and PI should benefit from the industry tailwinds.

While PI’s price declined 19.6% over the past month, SWKS surged 11.2%. In terms of their past six months’ performance, SWKS is again a clear winner with 16% gains versus PI’s negative returns. But, which of these stocks is a better pick now? Let’s find out.

Latest Movements

In an announcement dated June 23, 2021, SWKS and Xilinx, Inc. (XLNX), a supplier of programmable logic devices, reported compliance with 3GPP linearity and bandwidth requirements for C-band signals. Using XLNX’s Zynq RFSoC Gen 3 and SWKS’ SKY66523-11 high-efficiency power amplifier (PA), the 280 MHz instantaneous bandwidth (IBW) solution has an operational frequency range of 3550 to 4200 MHz. At nearly $81 billion, the recent U.S. Federal Communication Commission (FCC) auction of 280 MHz C-band spectrum was the highest-value spectrum sale in history. Both companies hope to capitalize on the emergence of 5G technology.

On April 22, 2021, SWKS inked a definitive agreement with Silicon Laboratories Inc. (SLAB), a leading silicon, software, and solutions provider, to acquire SLAB’s Infrastructure & Automotive business in an all-cash asset transaction valued at $2.75 billion. The acquisition encompasses the technology portfolios and related assets of SLAB’s power/isolation, timing, and broadcast product lines, accelerating SWKS’ capabilities in the automotive, communications, and industrial markets.

On June 15, 2021, PI introduced three next-generation E710, E510, and E310 RAIN RFID reader chips that address the increasing demand for item connectivity in retail, supply chain and logistics, consumer electronics, and many other markets. With industry-leading system integration and easy-to-use development tools, this high-performance, low-power systems-on-chips (SoCs) enables the development of quick-to-market IoT devices that reliably identify, locate, and authenticate connected things. The company is likely to witness rising demand from IoT device makers in the coming months.

As of February 10, 2021, PI had shipped more than 50 billion endpoint integrated circuits (ICs) and three million connectivity ICs and devices across diverse markets, including retail, supply chain and logistics, healthcare, automotive, and air transportation. The company achieved this milestone in just over two years, highlighting the opportunity available for RAIN RFID and IoT expansion. By helping businesses transform digitally, PI is looking forward to achieving  expanded market reach for RAIN RFID and ICs.
