Updated Aug 12, 2026Q4 FY2026 reviewed
Richardson Electronics manufactures engineered power, RF, and microwave components used in semiconductor wafer fab equipment that supports AI/data-center capacity buildouts.
Q4 revenue +27.6%
Eighth straight YoY growth; highest quarter since Q3 FY23.
Backlog $164.4M
Highest in three years, up 8.7% from Q3 FY2026.
PMT ex-health +31.1%
Semiconductor wafer fab demand seen continuing into FY2027.
FY26 GES +7.3%
Below Q3 double-digit language; segment stays project-driven.
The Buildout Takeaway
All three business units grew in Q4 FY2026, and backlog built in the same quarter—growth is no longer just an easy-compare story. The open question is whether newer platforms like battery storage and Made in America convert from pipelines into repeatable revenue without product-mix margin erosion.

Our View

The Verdict

Richardson Electronics makes engineered power, RF, and microwave components for industrial and scientific equipment, with semiconductor wafer fab tools the clearest AI-infrastructure link. It also builds green-energy power-management products such as wind pitch energy modules and battery energy storage systems, plus custom displays for medical and industrial OEMs. The company is an indirect supplier: AI and data-center demand lift semiconductor capacity investment, which then pulls its components into wafer fab equipment.

What We Like

  • FY2026 net sales reached $228.6M, up 9.4% from $208.9M—the second consecutive annual sales increase.
  • Q4 FY2026 net sales rose 27.6% to $66.2M, the eighth straight YoY gain and highest quarterly sales since Q3 FY2023.
  • Total backlog ended FY2026 at $164.4M, the highest in three years and up 8.7% from Q3; Canvys posted a 1.3 book-to-bill.
  • PMT excluding legacy healthcare grew 31.1% in Q4 to $47.1M on semiconductor wafer fab demand; customer feedback points through FY2027.
  • The company says 55–60% of products sold are manufactured directly or exclusively to its specification; FY2026 ended with $31.8M cash and no revolver debt.

What We’re Watching

  • The expected multimillion-dollar BES order was still a forward commitment as of the Q4 FY2026 call; management only said it expects to announce it in Q1 FY2027.
  • Full-year GES growth of 7.3% fell short of the Q3 call's double-digit language; project timing remains a swing factor.
  • GE warranty approval is site-specific, not blanket; the first Canadian site shipped in Q1 FY2027, but the pace of next approvals is uncertain.
  • Q4 gross margin declined 40 bps YoY to 31.2% on PMT/GES mix, so revenue growth has not yet lifted margins.
Bottom Line

The thesis is strengthening on momentum: revenue accelerated across all three units, backlog is at a three-year high, and newer programs have moved from discussion to shipped/demo activity. The main open question is execution—most of the largest catalysts are forward commitments rather than reported revenue, starting with the promised multimillion-dollar BES order in Q1 FY2027.

Next upThe nearest test is Q1 FY2027, when management expects the multimillion-dollar BES order announcement, the LaFox BES design center, and the 20 Nm PEM launch. It will show whether the largest forward commitments begin converting into booked business.
Last Quarter — Q4 FY2026

Earnings Beat

Q4 FY2026 net sales rose 27.6% to $66.2M from $51.9M, with gross margin at 31.2%, down 40 bps. Net income increased to $3.7M from $1.1M, and EBITDA was $4.7M. The quarter was the eighth consecutive year-over-year sales increase and the highest since Q3 fiscal 2023.

I am pleased to report that Richardson Electronics delivered both a strong fourth quarter and finished the fiscal year 2026.— Edward J. Richardson, CEO, 2026-07-23

Management tone: Management shifted from a measured Q3 tone to a more confident Q4 tone, using milestone language such as 'accelerating momentum' after shipping the first BES system. In Q&A, executives were direct about limited semiconductor visibility, GE's site-specific warranty process, and why capital allocation priorities had not changed.

Management Guidance

No consolidated numerical guidance was issued. Management's FY2027 commentary is qualitative: 'we believe FY 2027 will be another year of growth for both PMT and GES' and 'stronger growth in FY2027.' The Q3 call had forecast double-digit GES revenue growth, but full-year FY2026 GES growth was 7.3%.

Business Trajectory

Trajectory

Trailing revenue stepped up through FY2026: $52.3M in Q2 FY2026, $55.5M in Q3, and $66.2M in Q4, a 19.3% sequential rise. Full-year revenue grew 9.4% to $228.6M, driven by semiconductor wafer fab demand in PMT, higher wind product sales in GES, and a record Canvys quarter. Gross margin has held near 31%, while EBITDA margin expanded to 7.2% in Q4; the weak spot is cash conversion, with TTM free cash flow negative $9.6M tied to the completed Talos inventory build.

The Model

The model projects FY+1 revenue of $245.5M with EBITDA of $14M (5.8%), then FY+2 revenue of $262.5M with EBITDA of $18M (6.9%). The near-term path is anchored by current backlog and semiconductor wafer fab strength; the FY+2 step assumes battery energy storage, wind aftermarket, and Made in America programs scale into visible revenue.

The Q3 call had forecast double-digit GES revenue growth, but full-year FY2026 GES growth was 7.3%.

What Could Go Right — and Wrong

What good looks like
  • The promised multimillion-dollar BES order arrives in Q1 FY2027 and is followed by additional orders.
  • GE warranty approvals expand beyond the first Canadian site, unlocking the 15–20% wind SAM expansion management cited.
  • PMT ex-healthcare growth stays in the 20–30% range through calendar 2027 if wafer fab customers follow through.
  • Made in America discussions convert into production purchase orders later in FY2027.
  • Canvys holds book-to-bill above 1.0 and continues adding medical OEM backlog.
What could go wrong
  • The BES order slips beyond Q1 FY2027 or the nearly/over 50-opportunity pipeline stalls.
  • Semiconductor wafer fab demand rolls over, reversing the PMT acceleration.
  • A top-four GE wind owner-operator reduces purchases, or GE site-specific approvals stall.
  • The $45M Talos inventory position proves too large or too specific, delaying cash conversion.
  • Product mix keeps pressure on gross margin even as revenue grows.
What’s Next

Looking Ahead

The next twelve months are framed by management's own commitments: Q1 FY2027 brings the expected multimillion-dollar BES order, the LaFox BES design center, and the 20 Nm PEM launch. Later in FY2027, Made in America programs are expected to convert to revenue, and GE warranty expansion is key, with the first Canadian site already shipped in Q1 FY2027.

Catalysts
  • Q1 FY2027Multimillion-dollar BES order — Nearest dated commitment; tests pipeline conversion to backlog.
  • Q1 FY2027LaFox BES design center — Needs ComEd grid hookup; expected online in Q1.
  • Q1 FY202720 Nm PEM launch — Expands wind aftermarket to smaller turbines.
  • Q1 FY2027 onwardGE warranty site approvals — First Canada site shipped; next sites uncertain.
  • Later FY2027Made in America revenue conversion — Restaurant kiosk and defense program orders to watch.
  • OngoingCanvys backlog conversion — Watch whether book-to-bill stays above 1.0.

The Company

Richardson Electronics is a global provider of engineered solutions, green energy products, power grid and microwave tubes, related consumables, power conversion and RF/microwave components, and customized display solutions. Its largest segment, PMT, supplies power, RF, and microwave products used in semiconductor wafer fab equipment and other industrial/scientific markets; GES covers wind, solar, hydrogen, EV, and power management; Canvys makes custom displays. The 10-K says more than 55% of products are manufactured in LaFox, Illinois, Marlborough, Massachusetts, or Donaueschingen, Germany, or by manufacturing partners—management clarified the range as 55–60%.

The company operates from an owned LaFox, Illinois campus of roughly 100 acres and 224,000 square feet, plus leased locations including Donaueschingen, Amsterdam, Hook, Singapore, São Paulo, Shanghai, and Bangkok. Management says roughly 60% of sales are outside North America. FY2026 ended with $31.8M cash, no outstanding debt on the PNC revolver, and the $45M Talos inventory build complete.

Competitive Landscape

The source material indicates RELL competes with a limited number of Chinese vacuum tube manufacturers whose capabilities 'have progressed over the past several years'; its wind aftermarket position rests on exclusive partnerships with the top four GE owner-operators. In BES, the company is early-stage and still small relative to the overall business.
