Investment Thesis

The GaN market will grow significantly faster than the overall power electronics market. The acquisition of GeneSiC opens additional SiC lanes for growth. There will be room for multiple successful companies.

Navitas Semiconductor (NASDAQ:NVTS) is in the right place, at the right time, with the right technology to capitalize on the generational shift from silicon to GaN and SiC in power electronics and earn well above market returns.

Introduction

I recently wrote an overview article on Navitas Semiconductor, and another on Transphorm, Inc. (TGAN), both fairly similar small cap semiconductor companies.

In a December 2021 interview, Gene Sheridan, CEO of NVTS, said:

In total, there are probably a dozen companies with GaN programs right now... This is the Wild West and it's kind of a land grab for market share right now - we estimate the GaN market could be worth more than $2 billion by 2026, so there's a lot of room for a multiple companies to be profitable.

In this article, I want to take a deeper dive into the competitors in this race for market share.

To recap, the market we are talking about is for power electronics, and GaN and SiC power electronics in particular. Power electronics are the devices that control, convert, or manage electrical power.

The GaN power electronics market is today a very small subset of the total power electronics market. Essentially, every GaN device sold is displacing a Silicon "Si" or Silicon Carbide "SiC" device in a product, where there are established competitors already selling those devices. Winning those "design-ins" is largely dependent on the advantages GaN provides.

This article from EDN Asia, written by GaN Systems, nicely summarizes the advantages of GaN:

The value of GaN from a system perspective comes from size, weight, and cost reductions, the latter including BOM cost (the cost of other system components such as capacitors, heat sinks, and inductors), usage cost, and cooling cost. For example, changing from Si to GaN in a power supply can slash the size of magnetic components such as transformers. All of this can be accomplished while achieving better efficiency, or better power density, and possibly both.

The information here comes from Seeking Alpha, company websites, quarterly earnings reports and calls, and industry news reports.

Q2 Results

NVTS announced Q2 results on 15 August 2022. The big news was the acquisition of GeneSiC (discussed in the next section). Overall, very good progress.

Q2 revenues increase 58% year on year, and 28% from the last quarter. Success in the mobile fast charger market continued, with a 200 watt charger and with design-ins with all 10 of the top 10 mobile OEMs for next generation chargers.

NVTS also has multiple design-ins for data center and residential solar, and in the appliance motor drive market in Europe. In on-board charging for EVs, five major customer programs are now in process, and expected generate 2025 revenue.

Secular weakness was evident in the Chinese smartphone market, and is expected to continue for at least one, and possible several, quarters.

Non-GAAP net loss from operations was $8.9 million compared to a net loss of $5.8 million in Q2 2021. Cash was $240 million prior to the acquisition.

The GeneSiC Acquisition

The GeneSiC acquisition, effective 15 August, expands the scope for NVTS from GaN only to GaN and SiC.

Founded in 2004, with their first commercial product in 2011, GeneSiC brings 19 employees and a broad range of 50+ high power SiC MOSFETs, with proven performance, robustness, and reliability, and 500+ existing customers.

Navitas expects "the GeneSiC acquisition will accelerate its expansion into higher-power markets by two to three years, with immediate Q3 revenue in synergistic solar, energy storage and EV markets, among other industrial markets".

Financially, GeneSiC is profitable, with current year revenues of ~ $25 million. NVTS paid a significant amount for GeneSiC; ~ $100 million in cash, $25 million in shares of NVTS stock plus a potential $25 million earn out. [Note: The press release says 25 million shares, the earnings call transcript says $25 million in shares.]

Market Size

There are multiple estimates of the market for power electronics in total and GaN and SiC in particular. In round numbers, the power electronics market is about $20-25 billion, with an estimated 5-7% CAGR for the next 5-10 years (see for example here, here, and here).

SiC will capture a significant share of the power market. See this MicroNews report for a summary of the state of play in SiC, which notes that "the SiC device market will reach US$6.3 billion in 2027", with major players adopting a vertically integrated (i.e. own their own fabs) model.

In a December 2021 interview, Gene Sheridan, CEO of NVTS, said regarding the competition between SiC vs. GaN:

SiC is great for extreme high-power, high-voltage applications and is 10 to 15 years more mature than GaN, and therefore more accepted.

So the real battleground for GaN and SiC is going to be with traction inverters and motor drives.

The estimates for the GaN market have much greater variance, reflecting in part that some estimates aggregate power electronics and other GaN markets (e.g. RF). The general market research estimates suggest 22-25% GAGR for GaN power electronics (see for example here, here, here, and here), i.e. at 3-4 times the rate of the overall power electronics market.

Semiconductor Today reported in October 2021 that the GaN power device market was estimated to reach $83 million in 2021 (e.g. ~1% of the power electronics market.)

The estimates from the actual GaN focused market participants suggest higher growth.

Infineon estimates "the GaN market is also predicted to undergo massive growth – from $47 million in 2020 to $801 million in 2025 (CAGR: 76%)".

We notes above the NVTS estimate that "the GaN market could be worth more than $2 billion by 2026".

Looking out 10 years, the overall power electronics market might be ~ $40 billion, and the GaN market ~ $6 billion, and the SiC market ~ $10 billion. Ten years is a long time, but it's probably safe to say the market is going to be a lot bigger than it is today.

The Competitors

I put together a list of competitors by combining the 10 identified by NVTS, and the 11 identified by TGAN, and added one more, Nexperia. Both NVTS and TGAN also noted the technologies (Si, SiC, GaN) for each competitor.

The result was a list of 15 companies. By comparison, Seeking Alpha lists 66 stocks in the Semiconductor industry.

The information is summarized in the table immediately below. I've sorted he companies into the large "majors", the smaller "GaN focused", leaving three companies falling by size and focus into a third Middle Zone (I promoted NVTS into that zone today). See also the short summary of each company in the next "Elevator Pitch" section.

Longer Term

Longer term, China looms. China's 14th Five Year Plan (2021-2025) specifically targets semiconductors, including "wide-gap semiconductors (e.g., silicon carbide, gallium nitride". ESN Asia notes that:

A Bloomberg report shows that 19 of the world’s 20 fastest-growing semiconductor firms are in China, which amounted to 8 just a year ago. Moreover, according to the China Semiconductor Industry Association, total sales of chip firms in China rose 18% to more than $150 billion in 2021.

New fabs are being built for power semiconductors, among them a CR Micro fab in Chongqing, China for power semiconductors, and the other fab in Xiamen, China, owned by Silan Microelectronics, to produce power discretes and sensors.

It seems likely that at least one major state owned/controlled firm will emerge.

Analysis

After looking at these competitors in power electronics space, I will offer some speculation.

One might draw a parallel here with the oil industry, with major oil companies and smaller independents. The majors are big, with deep pockets, broad scope, and long term strategic plans. The independents are small, with limited financial resources, more focus, and dynamic and opportunistic plans.

In our case, the competitors similarly group into the established majors and the GaN focused independents, with a three (including NVTS after the GeneSiC acquisition) falling into a middle zone.

The power electronics space in 10 years will be ~ $40 billion, and will include Si, SiC, and GaN technology. There are big investments by sophisticated players now being made in both GaN and SiC.

It's unclear how much of the market GaN will capture, but a $5-6 billion GaN market seems consistent with many projections. SiC will probably be larger. There will be multiple companies in the GaN and SiC power electronics spaces. I think not more than three will have more than 10% market share. Infineon and someone in China will likely be two of those.

The competitors are in land rush mode for the GaN share of that market; this is likely to last for several years. If you think of a quarter per lap; we probably have 20-30 laps before the winners will be evident.

The Current Lap

Measure by revenue, the table below suggest how the customers think the race is going for select competitors (the public GaN focused plus the two in the grey zone).

Risks

Three risks to this competitive analysis stand out.

1. Strategic shift by a major player. Any of the majors could make a strategic decision at any time to get into GaN in a big way. Most of the smaller GaN focused companies are basically ~ a hundred key people - managers, engineers, marketing and sales - and a set of relationships with suppliers and clients. A major could match this relatively quickly if it became a priority, perhaps aided by one or more acquisitions, and significantly change the competitive landscape.

2. Geopolitical risk. Production and sales both cross geopolitical boundaries today. That could become very problematic at any time; some of the smaller players might not survive such a disruption.

3. There is very limited visibility into the non-public companies.

Investor Takeaway

The GaN market will grow faster, perhaps 3-4x or more faster, than the overall power electronics market. The SiC market will grow somewhat slower than GaN, but from a larger base. There will be room for multiple successful companies.

The acquisition of GeneSiC should accelerate NVTS growth and market share capture. TGAN may need to step up their game.

GaN Systems and Efficient Power Corporation will probably need to go public to raise the capital to effectively compete.

In a November 2021 interview CEO Jim Witham of GaN Systems said, speaking about their recent $150 million funding round with lead investor Fidelity, previous investor BMW iVentures, and new investor Vitesco, said:

I see a lot of benefits having a nice big private round, we can really concentrate on customers and growing the revenue line and really take advantage of this tipping point so it was a conscious decision for us to go to Fidelity.

What I am trying to is build a great company, taking advantage of this transition and... you have to do is you have to have the capital to get it done.

It's difficult to predict at this stage who will take the Gold, Silver, and Bronze in this race. A wise investor might consider a portfolio approach.

Here's what the market thinks about the progress of the race year-to-date.

Data by YCharts

If NVTS and the independents can grow materially, they will become increasingly attractive acquisition targets of the majors. I believe they would be more attractive as a profitable business with a positive cash flow than as a technology hedge. I'd expect the winners to reach this point ~ 2025-2027.

Personally, I have small investments in NVTS and TGAN. Ideally, I'd like to split my chips among NVTS, TGAN, and GaN Systems. I think there is a fair chance of one or more of them taking home a Gold, Silver, or Bronze.
