Newly Issued Patent to Support the Continued Replacement of Wind Turbine Batteries with Ultracapacitor Module Technology

LaFox, IL | March 22, 2023 –Richardson Electronics, Ltd. (NASDAQ: RELL), a global provider of engineered solutions for renewable energy, is pleased to announce the issuance of U.S. Patent No. 11,624,348 (the ’348 Patent). The ’348 Patent is the third patent covering the Company’s Pitch Energy module with additional U.S. and foreign patents still pending.

Richardson’s most recent patent reflects the ingenuity in its market-leading solution, the ULTRA3000^® Pitch Energy Module (PEM). The ULTRA3000^® is a drop-in replacement for lead acid batteries within electric pitch systems. With its true plug-and-play technology, owners can replace one battery at a time on an as needed basis or retrofit the entire pitch system. With over 35,000 PEMs installed, Richardson Electronics’ ULTRA3000^® has become the owner operators’ number one choice for ultracapacitor based pitch systems. With the increased reliability of ultracapacitors over lead acid batteries owners can reduce nuisance battery faults and increase wind turbine availability.

Greg Peloquin, Executive Vice President, and General Manager of Power Microwave and Green Energy Solutions Group, stated, “Richardson continues to innovate in the renewable energy market, devoting substantial engineering expertise and intellectual property in expanding its patent portfolio. RELL will continue to add technology partners, engineered solutions, and key customers to this fast-growing market.”

• Preliminary FY23 Q3 net sales estimated to exceed $70 million, an increase of 27% over the prior year third quarter, subject to final review
• Preliminary backlog is estimated to be $175.1 million
• Preliminary operating income is estimated to be $7.6 million subject to final review, or 10.8% of net sales, an increase of 110% over the prior year quarter

LaFox, IL, March 21, 2023:  Richardson Electronics, Ltd. (NASDAQ: RELL) today announced preliminary results for its third quarter ended February 25, 2023, in conjunction with the Company’s presentation at the Sidoti & Company Virtual Small-Cap Investor Conference on Thursday, March 23, 2023.  The Webinar link is https://sidoti.zoom.us/webinar/register/WN_8E3Af1CmRfu8G0EXT6A1kA and the presentation is available on the Company’s investor relations website at https://www.rell.com/investor-relations.

Preliminary fiscal year 2023 third-quarter net sales are expected to exceed $70 million, subject to final review, representing a 27% increase from the prior year’s third quarter. Revenue increased across the Company’s Green Energy Solutions, Power and Microwave Technologies, and Canvys business units from the same period a year ago due to strong end-market demand and successful growth initiatives.  Preliminary backlog is expected to be approximately $175.1 million, which is down from $192.6 million at the end of the second quarter, and stable from the third quarter a year ago.  Management expects operating income to increase 110% to $7.6 million subject to final review, or 10.8% of net sales, compared to $3.6 million, or 6.6% of net sales for the same period last year.

“Third quarter was another record sales quarter with high growth generated throughout most of our business units, which translated into robust operating income,” said Edward J. Richardson, Richardson Electronics’ Chief Executive Officer. “Sales to our semiconductor wafer fabrication equipment customers and our Green Energy Solutions group were particularly strong.  Backlog remains stable but was down from the second quarter primarily associated with lower orders from semiconductor customers.  Backlog in our Green Energy Solutions business increased 87.2% over the same period a year ago and was up 3.4% from second quarter levels.  We look forward to sharing our full financial results when we release third-quarter results on April 5, 2023.”

The above information is preliminary and subject to completion, including the completion of customary financial statement closing and review procedures for the quarter ended February 25, 2023. As a result, the preliminary results set forth above reflect the Company’s preliminary estimate with respect to such information, based on information currently available to management. The Company’s actual financial results for the quarter ended February 25, 2023, may differ materially from these preliminary financial results. Further, these preliminary estimates are not a comprehensive statement or estimate of the Company’s financial results for the quarter ended February 25, 2023. These preliminary estimates should not be viewed as a substitute for full interim financial statements prepared in accordance with GAAP and they are not necessarily indicative of the results to be achieved in any future period. Accordingly, you should not place undue reliance on these preliminary estimates.

These preliminary estimates were prepared by the Company’s management and are based upon a number of assumptions. Additional items that may require adjustments to these preliminary estimates may be identified and could result in material changes to these preliminary estimates. Preliminary estimates of results are inherently uncertain, and the Company undertakes no obligation to update this information.  The Company plans to issue financial results for the quarter ended February 25, 2023 on April 5, 2023.
