What Next For Navitas Stock After 2x Rise This Year?
Photo illustration byNavitas Semiconductor (NASDAQ:NVTS) is a firm that designs and produces next-generation power semiconductors utilized in consumer electronics, solar energy systems, and electric vehicles. It experienced a nearly 8% increase in stock price during Friday's trading session. The stock has effectively doubled year-to-date. This rise has been fueled by increasing investor confidence regarding Navitas' collaboration with Nvidia. In May, both companies declared their partnership aimed at Nvidia's state-of-the-art 800V high-voltage direct current (HVDC) architecture, which seeks to improve the energy efficiency and scalability of data centers. This agreement could establish Navitas as a provider of advanced silicon carbide (SiC) and gallium nitride (GaN) power chips for the new HVDC architecture, which Nvidia claims will reduce copper usage, minimize rack dimensions, and enhance reliability and efficiency. Although the collaboration with the AI processor giant is perceived as a vote of confidence in Navitas' capabilities, Navitas is only one of multiple suppliers involved in Nvidia's project. The proportion of Navitas content within each server system and the potential for revenue generation remain uncertain. Nvidia's press release mentioned other companies such as Infineon, MPS, ROHM, STMicroelectronics, and Texas Instruments, along with Navitas, as semiconductor suppliers for the initiative. (Related: RGTI Stock: Path To 10x Growth) Navitas Stock Appears Risky In general, Navitas Semiconductor (NVTS) stock does not seem appealing at its current valuation, primarily due to its high valuation and weak fundamentals. Our evaluation of Growth, Profitability, Financial Stability, and Downturn Resilience suggests that the company's operational performance and financial status are concerning. Nevertheless, if you are looking for upside potential with lower volatility compared to individual stocks, the Trefis High Quality portfolio offers an alternative, having outperformed the S&P 500 and yielded returns exceeding 91% since its launch. NVTS is trading at a premium, with a price-to-sales ratio surpassing 17x, compared to only 3.1 for the S&P 500. While the firm reported an impressive average revenue growth of 53.5% over the last three years, this growth has been inconsistent, with revenues decreasing by 16.9% in the past 12 months and plummeting by 39.5% year-over-year in the most recent quarter. Profitability also poses a challenge. Navitas recorded an operating loss of $122 million over the past year, resulting in an exceptionally weak operating margin of -164.2%, which is significantly worse than that of most of its competitors. On a brighter note, the balance sheet is relatively stable. Navitas holds just $6.9 million in debt, resulting in a low debt-to-equity ratio of 0.5% (in contrast to 19.4% for the S&P 500), as well as a strong cash-to-assets ratio of 20.3%. However, downturn resilience remains low. NVTS stock has performed significantly worse than the benchmark S&P 500 index during many recent downturns. While investors hope for a soft landing for the U.S. economy, what could happen if another recession occurs? Our dashboard How Low Can Stocks Go During A Market Crash illustrates how key stocks performed during and following the last six market crashes. While it may be wise to steer clear of NVTS stock for the time being, you might want to consider the Trefis Reinforced Value (RV) Portfolio, which has outperformed its all-cap stocks benchmark (a combination of the S&P 500, S&P mid-cap, and Russell 2000 benchmark indices) to deliver robust returns for investors. What makes this possible? The quarterly rebalanced mix of large-, mid-, and small-cap RV Portfolio stocks has offered an effective strategy to capitalize on positive market conditions while mitigating losses during market downturns, as detailed in the RV Portfolio performance metrics.

Why Silicon Carbide (SiC) is transforming future of electric vehicles
The global shift towards electric vehicles (EVs) is not just a matter of replacing petrol with batteries. At the core of this transformation lies a revolution in power electronics with SiC emerging as the enabler. SiC is fast replacing traditional silicon in key EV components, which otherwise suffer sharper drawbacks when it comes to efficiency, performance, and reliability. Silicon carbide is a compound semiconductor material with a very wide bandgap, high thermal conductivity, and able to operate at higher voltages and temperatures than conventional silicon. Special, intrinsic properties of SiC find critical suitability in the harsh environment of EVs, where efficiency, weight reduction, and reliability constitute the high priorities. Today, SiC enters major EV areas, such as: Inverters: Conversion of DC from the battery to AC for the motor (propulsion).DC-DC Converters: Step-down high-voltage battery power for auxiliary Chargers: Controlling the charging process from external Charging System (MCS): Connecting to high-power lines for faster charging. Key Benefits Operating with Higher Efficiency: Reduced switching and conduction losses in SiC devices mean less energy wasted as heat. This also means a greater driving range and better energy utilisation. Compact and Lightweight: The enhanced qualities of SiC allow for smaller, lightweight components, freeing space and adding to the reduction in vehicle Performance: Being good in heat dissipation, SiC requires less bulky cooling systems and can pave the way for reliable operation at elevated Charging: Since SiC-based chargers can be run more efficiently at high voltages, they can support faster charging of EV Cost Charging Stations: Integrated solid-state transformers utilizing high-voltage SiC devices (≥ 3.3 kV) reduce MCS cost, weight, and size. SiC's Impact on EV Performance MetricSiC vs Silicon PerformanceInverter EfficiencySiC: up to 99.1% vs Silicon: 97.1%Range Increase5% to 10% more range with SiCPower Loss ReductionUp to 70% lower switching lossesWeight and SizeInverters up to 40% lighter, 30% smallerCharging TimeSiC enables 800V (and higher) systems, halving charge timeBattery Cost SavingsSiC inverter can reduce battery size for same range, saving up to 5 per vehicle Major car makers are making use of SiC in their newest EVs. In the case of Audi, the use of SiC inverters has enhanced efficiency by nearly 60per cent under certain operating conditions. The 800V battery probably would not have come onstage if SiC had not been there, and it is now gaining traction in high-performance models from Kia, Hyundai, and Lucid, offering really fast charging and extended range. Additionally, the electrification of heavy-duty vehicles, such as buses, construction equipment and tractors, is also a significant and growing trend. These heavy-duty EVs are bigger and heavier than passenger EVs and require higher-power levels for propulsion and charging. To address these higher-power requirements, the adoption of higher battery voltages, particularly around 1500V, combined with higher-voltage SiC technology, plays a crucial role in enabling the electrification of heavy-duty vehicles. The increased efficiency of SiC-based systems results in less energy elimination and extends the range of EVs; and, therefore, reduces its overall impact on the environment. Small batteries equate to lighter vehicles that will consume fewer resources and emit fewer emissions during its lifespan. The other side of the coin is better reliability and durability that ultimately result in reduced maintenance and lower cost of ownership. Silicon carbide is no ordinary material technology; rather, it is becoming a truly defining factor for the new generation of EVs, fast charging infrastructure, and electrified transportation overall, such as eVTOL (Electric Vertical Take-Off and Landing) aircraft. By giving rise to greater efficiencies, longer ranges, shorter charge times, and smaller sizes, SiC directly addresses some of the greatest impediments to mass EV acceptance. With ongoing R&D, the role of SiC in shaping and enabling the future of sustainable mobility will get stronger; empower energy to do more.

Here's Why Aehr Test Systems Surged in June (Hint: It's AI related)
Aehr Test Systems is not a one-trick pony, and the company is impressively diversifying its revenue streams. The market is speculating that its new customers could prove lucrative and lasting. 10 stocks we like better than Aehr Test Systems › Aehr Test Systems (NASDAQ: AEHR) stock rose by 35.5% in June, according to data provided by S&P Global Market Intelligence. The move comes as positive developments in the end markets that Aehr is targeting helped support the idea that the company can diversify its revenue streams and improve its growth in the process. The company is best known for its test and burn-in equipment for the silicon carbide (SiC) wafer-level burn-in (WLBI) market. As management notes, this end market contributed 90% of Aehr's revenue in 2024. Unfortunately, at least from a near-term perspective, the key driver for Aehr's SiC WLBI solutions is the electric vehicle (EV) market and its associated charging infrastructure. Aehr's key customers in this market, which include ON Semiconductor, have come under pressure due to the ongoing relatively high interest rate negatively impacting EV sales. For reference, and by way of example, Wall Street analysts expect ON Semiconductor's sales to decline by 16.5% in 2025. Consequently, Aehr needs to develop other markets to help offset weakness in its core SiC WLBI market. And the good news is it's not only doing that, but those markets are also in growth mode. The progress was noted in the third-quarter earnings presentation in April with CEO Gayn Erickson outlining that SiC WLBI revenue is now tracking to "less than 40%, with artificial intelligence (AI) processors burn-in representing over 35% of our business in just the first year." Furthermore, in the third quarter, Aehr had four customers accounting for 10% of its revenue, with three of them coming from new markets for Aehr: WLBI for AI processors Packaged part burn-in (PPBI) "for qualification and ongoing process monitoring of AI processors" "WLBI of gallium nitride (GaN) semiconductors" Fast forward to June, and the positive momentum in AI and GaN WLBI spending has continued with Nvidia's well-received earnings report coming at the end of May. Moreover, Nvidia is working on developing a data center architecture for the next generation of data centers, starting in 2027, and has named GaN semiconductor company Navitas Semiconductor as a partner. As such, the market is speculating that Navitas could be a potential customer of Aehr Test Systems. The growth of alternative revenue streams is a significant plus for Aehr's investment case, and demand for SiC WLBI is likely to improve over time as EV investment is expected to increase. All told, the company's revenue and earnings remain highly cyclical, but its new end markets are helping to reduce its heavy reliance on EV spending, which has benefited the stock in June.

ROHM Launches an Isolated Gate Driver IC Optimized for High-Voltage GaN Devices
Isolated Gate Driver IC Santa Clara, CA and Kyoto, Japan, June 25, 2025 (GLOBE NEWSWIRE) -- ROHM Semiconductor today announced the development of the BM6GD11BFJ-LB, an isolated gate driver IC optimized for driving 600V-class high-voltage GaN HEMTs. When combined with GaN devices, this driver enables stable operation under high-frequency, high-speed switching conditions – contributing to greater miniaturization and efficiency in high-current applications such as motors and server power supplies. As global energy consumption continues to grow, energy-saving initiatives have become a shared global priority. Motors and power supplies alone are estimated to account for approx. 97% of the world's total electricity consumption. Achieving higher efficiency in these systems is increasingly dependent on utilizing wide bandgap devices such as SiC and GaN to control and convert electricity more efficiently. Leveraging expertise in developing isolated gate driver ICs for silicon semiconductors and SiC devices, ROHM has introduced this new IC as the first in a series of isolated gate driver solutions optimized for GaN devices. Safe signal transmission is achieved by isolating the device from the control circuitry during switching operations that involve rapid voltage rise and fall cycles. The BM6GD11BFJ-LB utilizes proprietary on-chip isolation technology to reduce parasitic capacitance, enabling high-frequency operation up to 2MHz. This maximizes the high-frequency switching capabilities of GaN devices. This contributes not only to greater energy efficiency and performance in applications but also reduces mounting area by minimizing the size of peripheral components. At the same time, CMTI (Common-Mode Transient Immunity - an indicator of noise tolerance in noise isolated gate driver ICs) has been increased to 150V/ns – 1.5 times higher than conventional products – preventing malfunctions caused by the high slew rates typical of GaN HEMT switching. The minimum pulse width has also been reduced to just 65ns, 33% less than conventional products. These performance improvements allow for stable, reliable operation at higher frequencies while minimizing power loss through better duty cycle control. With a gate drive voltage range of 4.5V to 6.0V and an isolation voltage of 2500Vrms, the BM6GD11BFJ-LB is designed to fully support a wide range of high-voltage GaN devices, including ROHM's newly added 650V EcoGaN™ HEMT. The industry-leading low output-side current consumption of 0.5mA (Max) also reduces standby power, improving overall system efficiency. EcoGaN™ is a trademark or registered trademark of ROHM Co., Ltd Application Examples◇ Industrial Equipment: Power supplies for PV inverters, ESS (Energy Storage Systems), communication base stations, servers, and industrial motors◇ Consumer Devices: White goods, AC adapters (USB chargers), PCs, TVs, refrigerators, Air Conditioners The BM6GD11BFJ-LB is now available. It is offered through online distributors such as DigiKey™ and Mouser™. The sample price is $4.0/unit (excluding tax). DigiKey™ and Mouser™ are trademarks or registered trademarks of their respective companies. Going forward, ROHM plans to offer gate driver ICs for GaN device control together with GaN device products, supporting simpler application design. TerminologyCommon-Mode Transient Immunity (CMTI)A key parameter of isolated gate drivers, CMTI refers to the driver's ability to withstand rapid voltage changes that occur over very short durations. This is especially important when driving high slew rate devices such as GaN HEMTs, where rapid voltage transitions are common. A gate driver with high CMTI can prevent device damage while reducing the risk of circuit shorts. Attachment Isolated Gate Driver IC CONTACT: Heike Mueller ROHM Semiconductor +1-408-720-1900 hmueller@
