Peers on Argus
RELL was down 2.92% while peers showed mixed momentum: some down (e.g., GAUZ median move about sector scanner’s -5.3%) and others up (e.g., LINK, NEON, ELTK). With 3 peers up and 2 down appearing in momentum scans, trading reflected broader cross-currents in electronic components rather than a purely idiosyncratic move.
Previous Partnership Reports
| Date | Event | Sentiment | Move | Catalyst |
|---|---|---|---|---|
| May 13 | BESS partnership | Positive | +8.1% | Partnership with Gotion for U.S.-manufactured BESS systems across C&I and utility. |
| Feb 10 | RF/microwave deal | Positive | +15.2% | Global Nxbeam partnership for high-power microwave MMICs up to 76 GHz. |
| Nov 12 | SiC expansion EMEA | Positive | -0.2% | Navitas partnership extending SiC power device distribution into EMEA regions. |
| Sep 17 | Capacitor partnership | Positive | +1.9% | Global agreement with Quantic to broaden high-reliability capacitor offerings. |
Partnership announcements have generally been received positively, with most prior deals producing single- to mid-teens percentage gains the next day, though there has been at least one flat-to-slightly-negative reaction.
Over the last year, Richardson Electronics has repeatedly used partnerships to expand its technology portfolio. Prior deals covered U.S.-manufactured BESS solutions (May 13, 2026), high-power microwave MMICs with Nxbeam (Feb 10, 2026), SiC power devices in EMEA via Navitas (Nov 12, 2024), and advanced capacitors with Quantic (Sep 17, 2024). Those announcements often supported exposure to electrification, RF, and power conversion markets, similar in theme to today’s SiC-focused collaboration.
Historical Comparison
Over the past four partnership announcements, RELL’s average next-day move was about 6.25%, with most deals generating positive reactions, underscoring investor focus on strategic technology collaborations.
Partnerships show a progression toward higher-value power and RF content: from capacitors and RF MMICs to SiC power devices and BESS, steadily deepening exposure to electrification and advanced power conversion.
Market Pulse Summary
The stock moved +9.7% in the session following this news. A strong positive reaction aligns with how RELL often traded after prior partnerships, which on average moved about 6.25% the next day. Investors have historically rewarded deals that deepen exposure to electrification, RF, and power conversion. However, past gains sometimes faded, and insider activity has included recent sales, so reliance on partnership headlines alone without follow-through in revenue and margins could lead to reversals.

Expands silicon carbide portfolio to capture growth in electrification and high-efficiency power markets
LAFOX, Ill., May 20, 2026 (GLOBE NEWSWIRE) -- Richardson Electronics, Ltd. (NASDAQ: RELL) today announced a new global strategic partnership with NoMIS Power, a leading designer of advanced silicon carbide (SiC) power semiconductor technologies.
Through this collaboration, Richardson Electronics will expand its portfolio of next-generation power solutions by leveraging NoMIS Power’s rugged, reliable, and customizable SiC technologies. The partnership adds targeted capabilities across 1.2 kV to 10 kV, with particular emphasis on medium-voltage and high-voltage SiC solutions at 3.3 kV and above for demanding power conversion applications.
The partnership is expected to accelerate the adoption of high-performance SiC technologies across key growth markets, including battery energy storage systems (BESS), renewable energy conversion, AI data center power infrastructure, high-voltage direct current (HVDC) interfaces, solid-state transformers, rail and heavy-duty transportation, industrial drives, aerospace and defense power systems, marine power, and other mission-critical electrification platforms.
For customers developing higher-voltage systems, the collaboration also strengthens Richardson Electronics’ ability to support the transition from legacy silicon insulated gate bipolar transistor (IGBT) solutions to more efficient SiC-based architectures. In these applications, SiC can enable lower switching losses, higher switching frequency, improved thermal performance, greater power density, and more compact system designs.
This partnership enhances Richardson Electronics’ - Power & Microwave Technologies portfolio by adding advanced silicon carbide devices and modules that address rapidly growing global end markets. The addition of high-efficiency, high-reliability SiC solutions further strengthens PMT’s position in electrification and power conversion applications, supporting long-term revenue growth and expanded market opportunities.
