Earnings Call Transcript - RELL Q4 2023

Operator, Operator

Good day, and thank you for standing by. Welcome to the Richardson Electronics Earnings Call for the Fourth Quarter and Fiscal Year 2023. Please be advised today's conference is being recorded. I would like to hand the conference over to your speaker today, Ed Richardson, please go ahead.

Ed Richardson, CEO

Good morning. And welcome to Richardson Electronics conference call for the fourth quarter of fiscal year 2023. Joining me today are Robert Ben, Chief Financial Officer; Wendy Diddell, Chief Operating Officer and General Manager for Richardson Healthcare; Greg Peloquin, General Manager of our Power & Microwave Technologies Group and our newest business unit, Green Energy Solutions; and Jens Ruppert, General Manager of Canvys. As a reminder, this call is being recorded and will be available for playback. I would also like to remind you that we'll be making forward-looking statements. They're based on current expectations and involve risks and uncertainties. Therefore, our actual results could be materially different. Please refer to our press release and SEC filings for an explanation of our risk factors. Fiscal year 2023 was one of the best years in our 76 year history. Operating income increased year-over-year by nearly 57% on a 16.9% increase in net sales, reflecting the power of our financial model. This growth demonstrates the success of our long term growth strategy, especially considering a fluid global economic environment, supply chain challenges and significant product and wage inflation. Over the past three years, we pursued organic growth strategies focused on expanding our product lines and leveraging the deep relationships we have with 20,000 customers all over the world. We've also greatly enhanced our engineering and manufacturing resources and capabilities. The success of these strategies has transformed our business by increasing our scale and significantly improving our profitability. Since fiscal 2020, annual sales have increased from $155.9 million to $262.7 million, representing a compound annual growth of 19%. We've also significantly enhanced the profitability of our business. Our gross margin has remained stable. We've controlled expenses. SG&A as a percentage of annual revenue was 32.9% for the year ended May 30, 2020 compared to 22.4% at May 27, 2023, the year we just finished. Positive operating leverage has transformed the profitability as we've grown from an operating loss of $1.7 million in fiscal 2020 to an operating income of nearly $25 million in fiscal 2023. Most importantly, the growth we've achieved over the last three fiscal years and more recently in fiscal 2023 has been driven by new products and applications development, new customer growth and expanded relationships with our global customer base. The launch of our Green Energy Solutions business this year is a notable example of our successful strategies as GES Sales in fiscal 2023 grew by 110%. Not only did this support our performance in fiscal 2023 but our GES segment has further diversified our business and is helping us insulate from the challenging semiconductor wafer fab market. While we expect the semiconductor wafer fab market to remain challenging over the next several quarters, we're excited by the significant opportunities we're pursuing across all our business units. We continue to develop new products and expand our global customer base. These products include power management systems for wind turbines, electric locomotives, hydrogen power, synthetic diamonds. We believe our continued growth of our GES business will help offset the expected 2024 decrease in the semiconductor wafer fab equipment business. Today, nearly 60% of our revenue comes from products we manufacture or have manufactured exclusively for us. Ultra capacitors and lithium iron phosphate battery modules, magnetrons, CT tubes and many other tubes and related products are manufactured by us in LaFox, Illinois. We engineer and manufacture custom display solutions for medical applications in Boston and Germany. To accommodate this growth, we continue to hire talented engineers with a focus on new product development. We're also adding manufacturing capacity through our LaFox facility renovation, which is expected to be completed this week. Recently, we had key OEM customers joined by their end users visit our operations here in LaFox. Each walked away with a list of products and opportunities they want us to explore in addition to the products they purchased from us to date. We're excited to show off our completely renovated building at our upcoming investor open house scheduled for August 22nd. Now, Greg, Wendy and Jens will provide more details on the quarter and fiscal year, including these key growth initiatives. First, Bob Ben, our Chief Financial Officer, will review our fourth quarter and fiscal year 2023 financial performance in more detail.

Robert Ben, CFO

Thank you, Ed, and good morning. I will review our financial results for our fourth quarter and fiscal year 2023 followed by a review of our cash position. In addition, please note that I will be discussing non-GAAP financial measures. I refer you to our fourth quarter fiscal year 2023 press release for a reconciliation of non-GAAP items to the comparable GAAP measures. Net sales for the fourth quarter fiscal 2023 were down 4.5% to $58.8 million compared to net sales of $61.6 million in the prior year's fourth quarter due to lower net sales in our PMT, Canvys and Healthcare business units, partially offset by higher sales in our GES business unit. Net sales for GES increased $5.8 million or 61.7% from last year's fourth quarter. GES combines our key technology partners and engineered solution capabilities to design and manufacture products for the fast growing green energy market and power management applications. PMT sales decreased by $8.3 million or 20.8% from last year's fourth quarter, driven primarily by a decline from manufactured products for our semiconductor wafer fabrication equipment customers. Canvys sales decreased slightly by $0.3 million or 3.2% due to the timing of shipments in North America. Richardson Healthcare sales also decreased slightly by $0.1 million or 2.7% due to decreases in parts and equipment sales, partially offset by higher CT tube sales. Total company backlog was $160.4 million at the end of the fourth quarter of fiscal 2023 versus $175.1 million at the end of the third quarter of fiscal 2023. Gross margin for the fourth quarter was 27.9% of net sales compared to 32.7% in last year's fourth quarter. PMT’s margin decreased to 29% from 35.2%, primarily due to product mix. GES’s margin decreased in the fourth quarter of fiscal 2023 to 23.4% from 31.1% in the prior year’s fourth quarter, also due to product mix. Canvys gross margin increased in the fourth quarter of fiscal 2023 to 32.9% from 30.7% in the prior year’s fourth quarter, because of product mix and lower freight costs. Healthcare’s gross margin increased to 23.7% in the fourth quarter of fiscal 2023 compared to 10.8% in the prior year’s fourth quarter due to improved manufacturing absorption, partially offset by increased scrap expense. Operating expenses were $15 million for the fourth quarter of fiscal 2023 compared to $15.2 million in the fourth quarter of fiscal 2022. The decrease in operating expenses resulted from tight expense control and lower incentive expenses from significantly lower operating income, partially offset by higher salaries expense, which included wage inflation. The company reported operating income of $1.4 million or 2.4% of net sales for the fourth quarter of fiscal 2023 versus operating income of $5 million or 8.1% of net sales in the fourth quarter of last year. Other income for the fourth quarter of fiscal 2023 including interest income and foreign exchange was $0.1 million compared to other expense of $0.2 million in the fourth quarter of fiscal 2022. Income tax benefit was $2.6 million and non-GAAP income tax benefit was $0.2 million for the fourth quarter of fiscal 2023 versus an income tax benefit of $3.5 million and non-GAAP income tax expense of $0.5 million in the prior year’s fourth quarter. The fourth quarter of fiscal 2023 included $0.4 million for an R&D tax credit for the current fiscal year and a one time total credit of $0.6 million for fiscal year 2020 through 2022. In addition, the fourth quarter of fiscal 2023 included a one time $1.8 million income tax benefit for the reversal of the foreign tax credit valuation allowance. Net income for the fourth quarter of fiscal 2023 was $4.1 million and non-GAAP net income was $1.8 million compared to net income of $8.3 million and non-GAAP net income of $4.3 million in the fourth quarter of fiscal 2022. Earnings per common share diluted were $0.27 and non-GAAP earnings per common share diluted were $0.11 in the fourth quarter of fiscal 2023 compared to earnings per common share diluted of $0.59 and non-GAAP earnings per common share diluted of $0.31 in the fourth quarter of fiscal 2022. Turning to a review of the results for fiscal year 2023. Net sales for fiscal year 2023 were $262.7 million, an increase of 16.9% from $224.6 million in fiscal year 2022. Net sales increased by $8.9 million or 5.7% for PMT, $25 million or 110.5% for GES, $4.1 million or 11.8% for Canvys and $0.1 million or 0.5% for Richardson Healthcare. Gross margin for fiscal 2023 was 31.9% of net sales, the same as during fiscal 2022. Operating expenses were $58.7 million for the fiscal year, which represented an increase of $3 million from last fiscal year. The increase in operating expenses resulted from higher employee compensation and travel expenses, including additional incentives expense due to strong profitability. Operating expenses as a percentage of sales decreased to 22.4% during fiscal 2023 as compared to 24.8% during fiscal 2022. Operating income for fiscal year 2023 was $25 million or 9.5% of net sales as compared to an operating income of $16 million or 7.1% of net sales for fiscal year 2022. Other income for fiscal 2023, including interest income and foreign exchange, was less than $0.1 million as compared to other expense of $0.2 million for fiscal 2022. Income tax expense was $2.7 million and non-GAAP income tax expense was $5 million for fiscal 2023. The fourth quarter of fiscal 2023 included $0.4 million for an R&D tax credit for the current fiscal year and a one time total credit of $0.6 million for fiscal years 2020 through 2022. In addition, the fourth quarter of fiscal 2023 included a one time $1.8 million income tax benefit for the reversal of the foreign tax credit valuation allowance. The income tax benefit of $2.2 million for fiscal 2022 resulted from the $4 million partial reversal of the tax valuation allowance due to evidence of profitability for realizing a portion of the deferred tax assets in the future. The non-GAAP income tax expense for fiscal 2022 was $1.8 million. The company reported net income for fiscal 2023 of $22.3 million and non-GAAP net income of $20 million versus net income of $17.9 million and non-GAAP net income of $13.9 million during fiscal 2022. Earnings per common share diluted were $1.55 and non-GAAP earnings per common share diluted were $1.39 for fiscal 2023 compared to earnings per common share diluted of $1.31 and non-GAAP earnings per common share diluted of $1.02 for fiscal 2022. Moving to a review of our cash position. Cash and investments at the end of fiscal 2023 were $25 million compared to $24.6 million at the end of the third quarter of fiscal 2023 and $40.5 million at the end of fiscal 2022. Cash generated in the fourth quarter of fiscal 2023 was primarily due to a decrease in accounts receivable, partially offset by an increase in inventory. The use of cash during the fiscal year related to higher working capital to support significant sales growth. US cash and investments were $7.6 million at the end of fiscal 2023 versus $8.9 million at the end of the third quarter of fiscal 2023 and $25.5 million at the end of fiscal 2022. Capital expenditures were $2.4 million in the fourth quarter of fiscal 2023 versus $1 million in the fourth quarter of fiscal 2022. Approximately $2.2 million related to investments in manufacturing, including facility expansion and the renovation of our office space. Total capital expenditures were $7.4 million in fiscal 2023 as compared to $3.1 million in fiscal 2022. We paid $0.8 million in cash dividends in the fourth quarter and a total of $3.3 million in fiscal year 2023. In addition, based on our current financial position, our Board of Directors declared a regular quarterly cash dividend of $0.06 per common share, which will be paid in the first quarter of fiscal 2024. As of the end of fiscal 2023, the company had not made any draws on its $30 million revolving line of credit with PNC Bank. Now I will turn the call over to Greg who will discuss the results for our PMT and GES business groups.

Greg Peloquin, General Manager, Power & Microwave Technologies Group

Thank you, Bob, and good morning, everyone. In fiscal year 2023, Power and Microwave Technologies or PMT and Green Energy Solutions or GES performed well with excellent growth in all aspects of the business. PMT revenue grew 5.7% while GES revenue increased 110.5%. The major highlight in the fourth quarter was our GES group as it continues to drive strong growth with addition of new products, new programs and new customers. Our GES group had exceptional growth throughout the quarter as the demand for green energy applications, such as wind energy, electric locomotives, energy storage and power management greatly increased. We continue to apply focus and resources to this extremely important strategic business unit and the growth opportunity it represents for Richardson Electronics. GES sales were up 61.7% in Q4 FY23 at $15.3 million versus $9.5 million last fiscal year. Our backlog is strong at $42.9 million. Revenues in GES include numerous successful products, such as the ULTRA3000 EV locomotive battery modules, ULTRAGEN3000 and products used in synthetic diamond manufacturing and other green advancements, such as hydrogen production and electric vehicles. In addition, we have numerous products in design, prototype, and beta testing. In the quarter, we continued to sign global technology partners and announced new patents and programs. We continually evaluate technologies to ensure we offer our customers the best most up-to-date solutions for their applications. In Q4, we announced the ULTRAPEM multi-brand module for several non-GE wind turbine platforms. We received a third patent on our ULTRA3000 and we announced that GE Vernova had selected the ULTRA3000 as the exclusive pitch energy module for the GE marketplace, increasing our served available market. We also announced the ULTRAUPS3000 used in wind turbines and other power management applications. This strategy of developing niche products and technologies is key to our long-term success. The growth of customers and products in GES continues as our design teams are in discussions with several major OEMs weekly regarding the development of energy storage products and other green energy applications. PMT sales in the fourth quarter of fiscal year 2023 decreased 20.8%, reaching $31.5 million versus $39.8 million in Q4 of last fiscal year. This decline was mainly due to the major slowdown in our semiconductor wafer fabrication equipment business. The team has been supporting this semiconductor wafer fabrication business and its customers for well over 25 years. This business has always been cyclical and we expected to see a slowdown in 2023. However, in talking to our customers, they expect the business to start recovering in the first half of calendar year 2024. Our engineered solution strategy is led by our global technology partners, such as Cuervo, MACOM, Anokiwave, Ellis Materials, AMOGREENTECH, Navitas Semiconductor and Fuji Semiconductor. Key tube manufacturers and partners include CPI, Thales, Nisshinbo Micro Devices and Photonis. Each of our global partners help us meet and manage customers’ requirements. Our team has done an excellent job identifying and cultivating these relationships. We will continue to add partners who fill technology gaps in our offering and support our growth. In Q4, we added ConductRF, a leader in RF cable assemblies. These key technology partners not only fill technology gaps in our component and engineered solutions offering but they also give us continued source of supply of new technologies to support all these new opportunities. Often through these partnerships, we identify opportunities for new products that we design to manufacture in-house, increasing the value we provide customers and allowing us to capture more market share and revenue. We also continue to invest in our infrastructure to support our growth. We are bringing on talented design and field engineers and making investments to enhance our manufacturing capabilities. Our growing in-house design, engineering and manufacturing teams are doing a great job supporting increased demand for current products and new product designs. I'm pleased with the progress we are making. With this team, we will continue to identify, develop and introduce new products and technologies for green energy and other power management applications. Our growth strategy has been proven successful over the years and we'll continue to develop new products as well as increase our customer base, revenue and profits by capitalizing on our existing demand creation infrastructure. Our belief in our future based on customer forecasts and inputs requires us to strategically invest in inventory that positions us in order to fill the pipeline and ensure we can meet our customers' needs through close collaboration with both our customers and suppliers. There are always headwinds, but we carefully manage these. We are prudently aligning with the business for a slowdown in the semiconductor wafer fab market over the near term, while maintaining our core competencies to support our wafer fab customers for the market expected to recover in calendar year 2024. Much of the green energy business is project-based and rollouts are dependent on our customers as well as their customers’ CapEx requirements. For example, we shipped over $18 million in products in FY23 to our Electric Locomotive customers, which they're using to build their prototypes. These trains will be finished and shipped to their customers in Q2 FY24. New production orders are expected until Q4 FY24. Also finding enough design and field engineering talent to support this growth continues to be a challenge. However, with Richardson's unique global model, continued growth and with our technology partners and a focused strategy, we'll subsidize the project-based business with products we engineer and manufacture to a very diverse customer base to have a more consistent, improved profitability with top line annual growth. We also continue to grow by gaining market share, introducing new products and technology partners and expanding the value we provide to our customers worldwide. I cannot stress enough the value of Richardson Electronics model to our customers and suppliers. Our unparalleled capability and global go-to-market strategy are unique to the power and energy, RF and microwave and green energy markets. We have developed a strong business model, including legacy products and new technology partners that fit with our engineered solutions capabilities. Through our steadfast and creative focus on customers, we'll continue to excel by taking advantage of opportunities when they arise. The execution of this strategy has never been better. There's no question our customers and technology partners need Richardson's products and support more than ever. We continue to be very excited about the future as opportunities and our market share for PMT and GES continue to grow. And with that, I'll turn it over to Wendy Diddell to discuss Richardson Healthcare.

Wendy Diddell, COO

Thanks, Greg. Good morning, everyone. Fourth quarter sales for Healthcare were $2.8 million, slightly lower than fourth quarter sales last year of $2.9 million. CT tube sales were higher in the quarter versus the same quarter last year. Parts and system sales were both down. On a full year basis, Healthcare sales were $11.4 million, just slightly above the prior year. System sales exceeded the prior year while part sales were down. CT tube sales were down less than 5% compared to last year. Gross margin in the fourth quarter improved significantly to 23.7% versus 10.8% in Q4 of last year, primarily reflecting better factory utilization. Last year, we were forced to stop production for a period due to supplier quality issues. On a full year basis, gross margin was 30.7%, a meaningful improvement over 21.2% last year. Much of the growth in gross margin was again due to positive production variances in FY23 stemming from enhanced operations. Scrap, while still high for the year, also decreased over the prior year. We are pleased with the improvement in gross margin as an indicator that we've ironed out many of the production challenges we've had in the past. We also want to point out that Healthcare's SG&A for the year was significantly below prior year. These savings, combined with the improved margin, resulted in reduced operating loss for healthcare compared to both our planned loss and our performance last year. We continue to make excellent progress on the Siemens repaired tube program. This is a series of four tube types, including the Straton Z, MX, MXP and MXP46. The Siemens installed base is considerably larger than Canon’s and there are no third-party replacement options for these tube types. The repaired Straton Z is now in full production and performing well in the field. We expect sales to rise gradually in the coming quarters based on early discussions with key customers. We are making excellent progress as well on the repaired Siemens MX series with a high degree of confidence that these will launch in the 2023 calendar year. We know demand is strong based on discussions we've had with our customers. As noted in prior calls, the Siemens program is a critical element for our Healthcare business unit to reach its goal of providing a positive operating contribution to the company by Q4 of FY24. Several new programs that will further improve CT tube sales and factory utilization are still underway. These programs include reloading tubes in Brazil. We continue to work our way through the local registration process. We are also partnering with an international company to reload and sell several other types in the Americas. We anticipate these programs may have a small yet positive impact on our revenue in FY24, depending on how quickly we can validate and achieve regulatory approvals.

Jens Ruppert, General Manager, Canvys

Thanks, Wendy, and good morning, everyone. Canvys engineers, manufacturers and sells custom displays to original equipment manufacturers and industrial and medical markets throughout the world. Canvys’ performance remains excellent with sales of $9.2 million for the fourth quarter of fiscal 2023. This reflects continued strong custom demand globally. Sales grew by 11.8% to $39.4 million in fiscal year 2023, the highest revenue since fiscal year 2012 due to increased demand globally and the continued addition of new customers and programs. This was a remarkable accomplishment considering ongoing supply chain and global economic challenges. Gross margin as a percentage of net sales was 32.9% during the fourth quarter of fiscal 2023 compared to 30.7% during the fourth quarter of fiscal 2022. The increase in gross margin was primarily related to the more favorable mix of higher margin products. Our fiscal year 2023 gross margin as a percentage of sales decreased slightly to 31.5% from 32% in fiscal year 2022. The decrease in gross margin was related to product mix and higher component costs, which impacted many companies around the globe, including Canvys. Our backlog remains extremely healthy, which we expect to support strong sales throughout fiscal 2024. Given the number of projects currently in the engineering stage, we are well positioned for continued growth. Our expectations assume no impact from current supply chain obstacles and demand is not negatively impacted by any potential recessionary pressures. During the quarter, we received several new orders from both existing and first-time medical OEM customers. Some of these applications include: ocular biometry, corneal cross-linking, refractive surgery, HMI to control medical devices within the operating theater, prostate biopsy, lithotripsy, dental treatment chairs, surgical navigation and laparoscopy. In the non-medical space, our products are used in a variety of commercial and industrial applications. These include flight simulators, displays used in control rooms, human machine interfaces for ticketing machines, teleprompting, talent monitors and clocks. I'm immensely proud of our teams around the world and I'm extremely pleased with the exceptional operating performance. Our strong and growing customer relationships along with the backlog position us for future growth in fiscal 2024 and beyond. From the variety of customers and applications as well as the value of orders from existing and new customers, it is clear we offer our global customers outstanding products and localized service. While our sales organizations stay focused on new opportunities, I stay focused on improving the operating performance of the division. Maximizing cash flow and improving Canvys’ profitability is an ongoing priority and we continue to work closely with our partners to meet the demands of our customers.

Ed Richardson, CEO

Congratulations, Jens, you and your team on setting another new sales record for Canvys and our custom display solutions. You and your team have aggressively attacked the medical OEM market and provided them with solutions they can't find anywhere else. As you've heard from Bob Ben and the business unit leaders, FY23 was phenomenal. While the semiconductor wafer fab cycle is expected to impact near term PMT sales, we believe we're well positioned to navigate the challenging market cycle. We continue to pursue organic growth strategies that leverage our global customer and supplier relationships, provide our customers with more engineered solutions and expand our manufacturing resources and capabilities. As a result, we're excited about the opportunities we have in front of us to significantly grow sales over the next three years and beyond. In addition, with our talented team and compelling products, I'm more confident about the direction we're headed than at any time as CEO of Richardson Electronics, which by the way has been 61 years. We continue to manage expenses and carefully evaluate every dollar we spend to ensure we're protecting our cash and maximizing our return. Our intent in FY24 is to use our cash to fund our key growth initiatives, while taking advantage of the money we've deployed so far. We firmly believe that developing solutions in a responsible manner alongside our suppliers and our customers is the key to our future success. We're scrutinizing inventory purchases. We review every capital expenditure and improve every addition to staff. We'll continue to explore and benefit from our favorable tax programs that support our green energy solutions. At this time, we'll be happy to answer some questions.

Operator, Operator

Our first question comes from Michael Hughes with SGF Capital Management.

Michael Hughes, Analyst

Ed, can you talk about the revenue generated from the semi cap equipment business in the just completed fiscal year, and what your expectation is for the coming year?

Ed Richardson, CEO

Yes. It was approximately $40 million, which included Lam Research, Applied Materials, Tokyo Electron, MKS, Thales and a number of firms. If you had heard the press release from Lam because of the CHIPS Act that Congress passed, they said their business would be down about 30% in the coming year, primarily because they couldn't ship high tech equipment to China. Since that time, they've come out with a much more optimistic forecast saying that by the end of 2024 their business will even be stronger than where it's been in the past. And they've even gone so far to tell their vendors we'll help support you financially to make sure you have the resources to supply our products when we need them.

Michael Hughes, Analyst

So $40 million in the just completed year. Do you have a ballpark number that we can think about for the coming year?

Ed Richardson, CEO

Yes. We're forecasting about $20 million and that may improve, but right now that's what it looks like.

Michael Hughes, Analyst

So that's about a $20 million headwind. And just my follow up, at a recent conference, I think you talked about a $290 million number potentially for the coming year, that's a pretty stout headwind that $20 million coupled with, it doesn't sound like there are going to be any rail orders, additional rail orders until the fourth quarter. Is that what Greg said? So just kind of maybe talk about the top line number for the coming year?

Ed Richardson, CEO

We think that there's enough business and various projects that we're working on in Green Energy that will more than compensate for the loss of business in the semi fab area. Now we have projects going not only for wind turbines, it was originally GE wind turbines, now Siemens wind turbines. We've been an approved source for GE for all of their customers. They tell us they have 800 on their electronic systems. In addition, we're making energy storage systems and we're working in the cellular field. As you know, we're working on the electric locomotives both for Progress Rail and Wabtec, which is the old General Electric facility. Each one of the diesel locomotives has what's called a battery start and those are lead acid batteries like 50 times what you'd have in a car. And we've developed either an ultra capacitor module or a lithium iron phosphate battery pack to replace those that gives them from seven to 10 years life. And we're in a prototype beta system on those and project that that could be very substantial in the future. There's something like 30 to 40 million diesel engines in use in the United States. So the replacement for those units is $3,000 to $5,000 a piece, you can just imagine what the potential is.

Wendy Diddell, COO

We should just clarify the thousand million, we wish there were 30 or 40 million…

Operator, Operator

Our next question comes from Anja Soderstrom with Sidoti.

Anja Soderstrom, Analyst

Can you just talk about the gross margin opportunity and how we should think about that in the coming years?

Ed Richardson, CEO

I think, overall our gross margin will run about 32% somewhere in that area, and that's a mix with all of our businesses. Certainly the semi fab business, which is very profitable, reduces our margin but we pick it up on the Green Energy Solutions where the business, particularly for wind turbines and energy storage systems and also the battery starts, is quite profitable.

Wendy Diddell, COO

Just to add on to Anja. I think, in FY24, as Ed mentioned, the semiconductor market has always been very profitable for us. So we'd be looking at a gross margin more in the 30% range for the FY24. We expect it to recover back into the range that Ed was pointing out.

Anja Soderstrom, Analyst

But since the GES is a little bit lumpy, right, that could pressure the margin in the near term as well, but as that revenue comes in that should help the margins, right?

Ed Richardson, CEO

The issue is not a matter of if. It's obvious these programs are all in progress. It's a matter of when and how quickly they'll be rolled out.

Anja Soderstrom, Analyst

And that will also help the gross margin…

Ed Richardson, CEO

That's right.

Anja Soderstrom, Analyst

It should be improving sequentially. In terms of the inventory, is there any risk associated with it, or can you get assistance from your customers regarding financing?

Ed Richardson, CEO

Well, we worked out programs with our suppliers. Greg, you might mention the one program you have where we have 180 day terms.

Greg Peloquin, General Manager, Power & Microwave Technologies Group

Yes. With all of our technology partners, we have zero liability. We have complete stock rotation of the product for the components. On the engineered solution side, we've developed great payment terms, because as we're all dealing with it's project-based. And due to lead times, we're collecting inventory. But there might be one or two parts that have to this day 30 week lead times. And so they've been very good in working with us, because we are designing disruptive technology for them. And so we've gotten good payment terms. So even though inventory might be up in a certain situation, if it is, we usually have signed either special terms or some sort of stock rotation capability if the product does not move at a certain date.

Operator, Operator

Our next question comes from P. Ross Taylor with ARS Investment Partners.

Ross Taylor, Analyst

A couple quick questions. One you talked about the idea of seeing semi cap equipment revenues drop from 40 to 20. We own in our larger cap products a number of the semi cap equipment companies, and pretty universally they see the quarter we're currently in as the trough revenue quarter. So would you explain to me why we should see revenues dropping meaningfully over coming quarters when they actually see revenues or they're expecting revenues to ramp over the next three, four quarters pretty sequentially?

Ed Richardson, CEO

Well, we based that on the first two quarters. And you're right, we've heard that they think the trough is in the next quarter or two. And if that happens then it'll turn up much faster. But we'd rather underpromise and overperform than to tell you that it's going to be 30 million, 40 million and it comes in at 20 million.

Ross Taylor, Analyst

Yes, I think the market is slightly apprehensive about that number, and I want to emphasize that there is a strong correlation between how similar companies perform historically, so we would expect to see an uptick in their results. Currently, the performance we are experiencing should reflect your situation. Moving on, could you discuss green energy? You've reported over a 60% increase in revenues, yet there seems to be only about a 22% rise in operating profit from that sector. That's quite a significant difference in margins. Can you clarify what margin this business operates at? Is it above 30% or in the low to mid-20% range?

Robert Ben, CFO

Yes, the overall margin for our green energy group is over 30%. In the fourth quarter, we made significant shipments of battery management systems to our largest electric locomotive customer. These were prototype builds, so the quantities and products were prototypes as well, resulting in lower margins until we achieve economies of scale during production. We support these large customers by offering them production pricing for the prototype shipments, accompanied by a letter of intent. Consequently, we experienced substantial shipments to our electric locomotive customers in the fourth quarter, which came with slightly lower margins compared to our overall margin.

Ross Taylor, Analyst

So we should expect that margin then to tick back up into the low 30s as we push forward. And you're seeing substantial growth overall in the GES space in the coming year as well, correct?

Robert Ben, CFO

Yes, correct. The balance of the business is in the mid 30s.

Ross Taylor, Analyst

This quarter was somewhat unusual. The challenges we faced this quarter were the result of various factors, but we expect them to correct themselves moving forward.

Robert Ben, CFO

We believe so, absolutely.

Ross Taylor, Analyst

And can you talk about backlog? Has the drop in backlog been tied in heavily to semi cap equipment?

Ed Richardson, CEO

Yes, we were running with a backlog in the semi equipment business over $40 million. And at the downturn, two things have happened. The Lam, for instance, they took everything they had on order everything we were manufacturing for them, so we filled their supply chain. And so now you get a last in that. But as we did that our backlog went down and we don't have new orders to replace it.

Ross Taylor, Analyst

But at the same time, they're indicating to you to be prepared to ship everything you can ship.

Ed Richardson, CEO

In the second six months.

Ross Taylor, Analyst

The potential for growth here should be significant and likely justifies a price-to-earnings ratio higher than 12. Although there are cash requirements outside the US, I believe it could be wise to maintain a net zero cash position and use that opportunity to conduct a Dutch auction in the current market to buy back a million to a million and a half shares. I doubt this will happen though. Once people start considering where we might stand in terms of earnings power in 12 to 18 months, it appears we should return to the trajectory we initially expected at the beginning of the year. This recovery should be enough to push the stock up 50% to 60% from its previous level, especially with a multiple exceeding 12. This seems like an excellent time to purchase stock.

Ed Richardson, CEO

Well, every Board meeting we consider it. As a matter of fact, when we sold RFPD in 2011, we bought $65 million worth of stock back at about $8.

Ross Taylor, Analyst

This appears to be another opportunity where the market is penalizing you for issues that are self-correcting. The next two years should really be a big success for your team. I will share this insight with the board.

Ed Richardson, CEO

What happens with the price of the stock, we'll see.

Operator, Operator

Our next question comes from Barry Mendel with Mendel Money Management.

Barry Mendel, Analyst

There was no mention of magnetron, and I know you guys are increasing capacity substantially of magnetron. Can you talk a little bit about the capacity expansion and what you're seeing there?

Ed Richardson, CEO

The demand for the YJ1600 for synthetic diamonds greatly exceeds our manufacturing capacity. We have significantly improved our manufacturing process, and our yields are back to normal. We believe that as time passes, we will be able to ship more. Currently, we still have about 5,000 units on backorder. This is, of course, dependent on product quality, which we believe has improved, but the demand is certainly strong.

Barry Mendel, Analyst

What is your backlog in terms of dollar amount or what you have in your backlog for that?

Ed Richardson, CEO

I don't know. Wendy, do you know the total backlog for magnetrons?

Wendy Diddell, COO

I don't have that handy.

Ed Richardson, CEO

It used to run about $15 million to $20 million. I'm not sure where it is today, but the YJ1600 sales per average price is about $3,000 and there's roughly 5,000 of those in backlog.

Barry Mendel, Analyst

And what kind of gross margins on that product?

Ed Richardson, CEO

It runs about 35%.

Barry Mendel, Analyst

So I would expect to see a substantial increase down in shipments this fiscal year is in the magnetron versus last year?

Ed Richardson, CEO

That's correct, yes. As long as we don't lose the formula, there's a lot of black magic in tubes.

Barry Mendel, Analyst

And I assume, and Wendy in Healthcare that you still expect breakeven by the fourth quarter?

Wendy Diddell, COO

We see the path to that. We're really excited about the progress we're seeing with the repaired Siemens program, not only from our own internal development perspective, which is going very well but from the customer response. We've talked to a large number of some of the larger companies that aren't even necessarily buying the cannon tubes from us because they don't serve as cannon equipment. And those can be obviously game changers for us. So lots of interest, making really good progress on the development of the repairs program. So yes, we still feel good about Q4 at a breakeven level.

Operator, Operator

Our next question comes from David Schneider, who's a Private Investor.

Unidentified Analyst, Analyst

I have a couple of comments and then a question. Recently, Stellantis automotive OEM announced they are working hard to secure semiconductor supplies globally for the next several years. It's worth considering that as vehicles transition from internal combustion engines to electric, the demand for semiconductors will significantly increase. This will ultimately benefit you, even if it’s not immediate. Regarding potential buybacks, given your small dividend, buying back shares means you won’t need to allocate after-tax cash flow for dividends on those shares. I’m advocating for that. Also, I'm curious about the shift to silicon carbide for automotive high voltage applications and whether your semiconductor capital equipment plays a unique role in that. Lastly, concerning Siemens wind turbines, it’s known that they’re facing issues with a notable percentage of their installed base due to subpar components. Does this situation make them more likely to consider you as an OEM supplier rather than replacing lead acid batteries? That’s all from me.

Greg Peloquin, General Manager, Power & Microwave Technologies Group

David, I'll touch on the Siemens question. It has no effect on our discussions with them so far with their network of wind turbines. They also service various wind farms that have different platforms. But we're full speed ahead with them on both the ultra UPS, the new product we announced in the fourth quarter and also the ULTRA3000 our variation of that for their turbines to replace what they currently have in there. So their issues are the same issues as all the owner operators and wind turbine manufacturers have had in terms of replacement costs of batteries that fail every 18 months to two years, both in the PEM system and the UPS and that's what we're focused on. And just today we shipped over 40,000 ULTRA3000s and those numbers will be similar as we roll out the UPS to those same customers.

Unidentified Analyst, Analyst

And then the other question was on the silicon carbide. Any special impact of that migration on your semiconductor equipment business?

Greg Peloquin, General Manager, Power & Microwave Technologies Group

No. In terms of delivery and parts being available, our technology partners and as you know, we have numerous silicon carbide technology partners. We've been fine. We have a major win in the electric vehicle market with VinFast out of Vietnam for their electric car. So we haven't seen, David, anything that would slowdown or subdue our opportunities or growth.

Operator, Operator

Our next question comes from Michael Hughes with SGF Capital Management.

Michael Hughes, Analyst

Just, you don't get a lot of questions on the legacy two business, but I think it's roughly 40% of revenue. So how did it perform in the just completed fiscal year and what's the outlook for the coming fiscal year?

Ed Richardson, CEO

Well, including the semiconductor wafer fab, which has tubes in it and wave guides and microwave devices, it went from a 100 million to about 120 million last year, so it was up substantially. And the core tube business is very strong and they told me 25 years ago we wouldn't sell tubes in five years and it was up over 20% this year, and we own about half the commercial market. So we wish there were more businesses like the tube business. But we sell to 20,000 customers all over the world, probably 80% of those products are in aftermarket. So it's a very predictable business.

Michael Hughes, Analyst

So the core business continues to perform well. And I think what's happened over time is maybe volume is in decline, but you take enough price each year to offset that. Is that how it works?

Ed Richardson, CEO

That's correct. That's right.

Greg Peloquin, General Manager, Power & Microwave Technologies Group

And yes, the Green Energy Solutions backlog is $43 million. Is that correct?

Michael Hughes, Analyst

Okay, I understand that business is rich with opportunities, but that number was down from, I think $54 million in the prior quarter. Is that just burning through some of the locomotive revenue, and should we expect a little bit of a pullback in the revenue for that division over the next couple of quarters and then a ramp in the back half?

Greg Peloquin, General Manager, Power & Microwave Technologies Group

That's exactly what it was. Again, that business and including most of the engineered solutions products in the Green Energy Group is project-based. So our bookings were through the roof as you remember in the first half of the year and then we designed and built it and shipped it. And so we had huge shipments in Q4 to meet our customers’ requirements so they could build their full electric locomotive. So I don't think we'll see production orders, as I mentioned, until Q3, Q4 of next year, large production orders. But we have some other products, I think, as Ed touched on with other electric locomotive manufacturers that should keep that top line growth going. But that's exactly, this is project-based. You're going to have that, you’re going to have huge bookings one quarter and then huge shipments a few quarters after that and then wait for the production. It's all part of the new product introduction process. And these are all, as you know, new products that didn't exist two years ago.

Michael Hughes, Analyst

Do you think the backlog that this was a low point and it can grow from here, meaning the book to bill would be north of one over the next few quarters for that division?

Greg Peloquin, General Manager, Power & Microwave Technologies Group

Yes, I think our bookings will be strong in Q1 and Q2 of this fiscal year. And then our top line, I think, will be stronger than any quarter we've seen in the last couple of years in Q3 and Q4.

Ed Richardson, CEO

Canvys is about $40 million…

Jens Ruppert, General Manager, Canvys

$47 million for Canvys, yes…

Wendy Diddell, COO

Yes, 47 for Canvys, PMT in total, but that includes Green Energy Solutions was $111.9, so I don't have it broken out here on my sheet and Healthcare was $1.7.

Robert Ben, CFO

Yes, actually I do have the backlog for PMT. It was $69 million and then $42.8 million for a total of both groups of $111 million.

Operator, Operator
