Jay
Thank you, Chris, and happy St. Patrick's Day, everyone. We're excited to discuss our 2022 results, and we'll do so shortly. But today, I want to take a little bit of time, take a step back, and answer a simple question. What is Nortec's value proposition? Though what we do here at Nortec is complex, the answer to this question is relatively simple. We engineer and manufacture complex, low-volume, high-mix, electromechanical systems, assemblies, and components for medical, industrial, and defense customers. And we do so on a global basis with plants in Minnesota, Monterey, Mexico, and Suzhou, China. Notably, we do not compete in the high volume, low mix space, which is dominated by larger companies like Benchmark and Plexus, admirable companies in their own right, whose factories churn out thousands of identical products every day, running multiple shifts. In contrast to those huge firms, Nortec will set up production lines that might run for a week or two, or maybe a month. We constantly take down lines and set up different lines. It's a fundamentally different business. And while we leverage some very sophisticated capital equipment in the production and testing, we primarily rely on our experienced, high-skilled, hands-on workforce to produce these very complex technical solutions. A $2 million to $5 million order is significant for us. And while larger contract manufacturers won't take that business, it's perfect for Nortec. Our largest customer accounts for roughly 25% of our revenue, but after that, our next largest customer is about 7%. We can effectively serve customers of any size that fit our global low-volume, high-mix, mission-critical business model. While Wall Street analysts may group all large and small EMS firms together, we do things that those larger firms cannot do or will not do. And candidly, they do things that we will not do. Occasionally, customers learn this fundamental difference in business philosophy the hard way. were currently negotiating with a medical customer that had first awarded their business to a large EMS firm. It was a relatively small contract for the relatively large EMS firm, and the customer was neglected. Consequently, quality and communication both suffered. The complicated, complex manufacturing process and supply chain was a poor fit for that large company's high-volume, low-mix model. Frustrated, that customer then pulled his manufacturing back in-house. but quickly recognizing and managing all the suppliers they've taken on, the cash implications of managing a lot of new inventory, and the complexity of their manufacturing process, that customer is now talking to us. And this situation fits Nortec perfectly. This simple story reflects what happens somewhat frequently. The Nortec team is very proud of what we do daily for our customers, and we feel we do it very well. It starts with taking great care of each other as Nortec employees and taking great care of our families. It's also very important to us that we take very good care of our supplier partners by communicating with them openly and honestly and paying them on time 100% of the time. It also means that we strive to be good corporate citizens locally, nationally, and globally. We know that if we take great care of all these critical stakeholders, employees and our families, customers, supplier partners, and our communities, we will also take great care of our shareholders. If there's a secret to our strong results in 2022, this is it. Now to explain our financials in more depth, we'll turn it over to Chris. Chris?
Chris Jones
All right. Thanks, Jay. So I will begin with the top line. And in Q4, 2022 revenue totaled $35.6 million. So this represents a 6.4% increase from revenue of $32.5 million in the fourth quarter of 2021. And it's up slightly from the prior quarter, increases year over year coming from both higher volume and previous pricing actions. For the full year 2022, revenue total of $134 million, a nearly 17% increase from revenue of $115 million in the full year of 2021. Nortec's revenue performance was driven by growth in net sales across all the markets that we serve. The medical market was up by about $13 million, or 20%, compared to 2021, with the majority of the increase coming from medical component products. In 2022, revenue from the industrial market was up $3 million, or 9%, from the prior year. And last, our aerospace and defense markets were also up from prior year levels by 17.5%, or $3 million. So, as I mentioned earlier, the overall year-over-year revenue improvement across all our markets was primarily due to a combination of higher production volume and pricing adjustments. Q4 gross profit totaled $5.1 million, or 14.3 percent, compared to a gross profit of $2.7 million, or 8 percent, from the prior year quarter. The fourth quarter margin was down on a sequential basis but we believe that over the long run, we are in a more stable gross margin position. For the full year, 2022 gross profit of $20.5 million, or 15.3% gross margin, was up from adjusted gross profit of $11.2 million, or 9.7% in the prior year. Notable in 2021 is that GAAP gross profit included the $4.7 million employee retention credit, And so our adjusted gross profit excludes that non-recurring item. The 83% year-over-year gross profit improvement and resulting 560 basis point improvement in year-over-year gross margin relates primarily to pricing actions to overcome inflationary cost pressures. Fourth quarter operating expenses totaled $4.4 million, which is a 23% increase from the fourth quarter 2021 operating expenses of $3.6 million, and it was flat on a sequential quarter basis. The $800,000 increase in year-over-year operating expenses was driven primarily by a $347,000 increase in selling expenses related to engineering and marketing to drive new business bookings for future quarters. Next, the majority of the $382,000 increase in year-over-year G&A costs was due to necessary investments in IT, HR, and analytical capabilities. And finally, a $174,000 increase in year-over-year research and development costs reflects continued investment in new technologies such as the active optical extreme cable platform. For full year 2022, income tax expense was $1.5 million compared to $900,000 in 2021. The effective tax rate in fiscal 2022 was 42 percent up from 12% in 2021. So that's a large change in tax rates. In 2022, the tax rate was driven by evaluation allowance from the Tax Cuts and Jobs Act requirement to capitalize and amortize research and experimental expenditures in 2022. And in 2021, our tax rate was driven by the non-taxable PPP loan forgiveness. Fourth quarter EBITDA totaled $1.2 million, which is a significant increase over an EBITDA loss of $400,000 in the fourth quarter of 2021. For the full year, EBITDA totaled $5.8 million, which is a $6 million improvement on an EBITDA loss of $200,000 in 2021. Both the fourth quarter and full year increases resulted primarily from previously discussed revenue and gross profit increases, offset by investments in operating capabilities. Moving on to the balance sheet and cash flow statement, first in 2022, cash provided by operating activities was $5.4 million, compared to cash used by operations of $4.5 million in 2021. Also notable in 2022, operating cash flow included the first of two $2.6 million payments from the IRS for the employee retention credit. The IRS is still processing NORTEC's second ERC application, and we hope to receive that payment at any time, but we have no visibility to when we will receive that payment. We also have a $1.2 million of deferred Social Security tax payments that will offset the final $2.6 million ERC payment. During the fourth quarter, net working capital improved by about $1 million as inventory levels of $22.4 million declined slightly from the prior quarter. Throughout 2022, we saw a gradual improvement in supply chain bottlenecks and component lead times. Nortec's supply chain team is working very closely with our customers and suppliers to ensure that the entire end-to-end supply chain is optimized for on-time delivery and working capital efficiency. We ended 2022 with $6.9 million of borrowings on our $16 million line of credit with Bank of America, and we had unused borrowing availability of $8.4 million. We believe that our... All right, so this is Chris Jones and Jay Miller, and we apologize for the technical problem. So I think the best place to restart our prepared comments is with Jay.
Jay
Thanks, Chris. Before we open the call up for questions, I want to touch on... Three topics, our strategic planning process, our investments in new technologies, and our ESG journey. Strategic planning is an ongoing process at Nortec, rather than just a once-a-year exercise. Our management team and board are always thinking ahead, beyond the next quarter or even fiscal year. For example, our current Nortec strategic plan covers 2023 to 2028, effectively six years ahead. Effective strategic planning for the future requires comprehensive, reliable information. In this effort, we're aided by our enterprise-wide ERP system that connects our entire organization. It enabled us to quickly adjust to demand fluctuations in this past year and will do so in the future while providing other vital insights. We implemented a new ERP a few years ago, and today is a vital tool for the whole leadership team as we run the business. Our strategic planning process also recognizes Nortec's growth history as a company. It's encouraging to look back four years, the span of my tenure as president and CEO, to see that we're a much healthier business today. We're much more financially stable, including our balance sheet and cash flows. Our internal team is significantly stronger at headquarters here in the Twin Cities and in all of our plants around Minnesota and Mexico and China. We have better customer relationships, more true partnerships today. Our supplier partnerships have also improved dramatically. And we're also better corporate citizens. We take better care of each other's employees, including our families. In each of the locations where we operate, Nortec is working to become a better community partner and a better place to work. This helps us attract and retain employees. And today our staffing levels are sufficient and stable. To stay on top of technologies that can help further distinguish us in the marketplace, we will continue leveraging our engineering expertise in new areas. Last year, we announced two exciting developments, launching our active optical extreme cable platform for machine vision and factory automation and receiving a U.S. patent for the Flex Faraday Extreme flexible printed circuit for high-frequency signals. Both are future-oriented technologies with exciting potential. They're also critical stepping stones to even better innovations that will help our customers in many ways, making their products more competitive, higher performance, lighter, more cyber secure, all while lowering overall costs. These innovations will make our products, and therefore our customers' products, cleaner environmentally and more sustainable. While we work to develop future technologies for our customers, we also must help them prepare for other challenges on the horizon. These include issues of sustainability within the context of ESG, environmental, social, and governance priorities. ESG may not be front and center on everyone's radar now, but it's only a matter of time. And NORTEC will be a proactive leader, not a follower. Note this, our R&D efforts are intimately tied to our ESG priorities. Tied directly to creating shareholder value, Nortec's board and management team are also committed to helping our customers and suppliers achieve these critically important ESG goals. We are in the initial stages of this journey, establishing baselines and developing plans. But relatively soon, we will begin to publicly report and track Nortec's ongoing ESG performance and progress in key areas. No business operates in a vacuum, and this effort demonstrates another way Nortec is committed to our employees, our families, customers, supplier partners, and shareholders, along with the greater world around us. And with that, we'll open things up to call up for questions. Ali, please open the line and poll for questions.

Paul Luber
Good morning, folks. I guess congratulations first off on a strong 2022. And I guess with that and kind of looking at the Q4 high tax rate, I'm curious what you anticipate the 2023 tax rate to run at and also kind of what you think normalized gross margins might be into the new year.
Chris Jones
Yeah, so this is Chris, and I'll take both of those on the tax rate and normalized gross profit margin. So on the tax rate, I think that, you know, Nortec had a unique occurrence in 2021 that made our effective tax rate low because of the PPP loan forgiveness. And then in 2022, we had a disproportionately high effective tax rate. And I think that was due to implementation of IRS rules around research and experimentation capitalization. So in 2023, neither one of those two unusual occurrences will occur. So I would expect a normal statutory income tax rate through 2023. And of course, we're working closely with our tax advisors to to work on any kind of cash, tax, credit opportunities, especially around things like research and development. So that's our 2023, certainly ongoing planning on taxes. On gross margin, our normalized full year gross margin last year was about 15%, which was obviously up significantly from 2021. And I think as we look at the at a kind of a stable gross margin, uh, pattern in 2022, I would expect that to continue into 2023. Uh, I think we have, we have a measured degree of headwinds on the margin side and tailwinds on the, on the margin side. So I, I think that's, that's something that, that obviously in 2023, we're going to continue to, uh, to focus on. And I, I think ultimately, uh, you know, as we think beyond 2023 and Nortec's broader, uh, planning on, on improving margin, it's, uh, It's adding more value to our customers. It's doing more higher-level assemblies, more complex products. And I think if you heard Jay's prepared remarks about ultimately the strategic direction of the company, it's toward higher margin products. But it's going to be methodical, and I think it's going to be stepwise, quarter on quarter.
Jay
This is Jay. First of all, thanks for your question. We appreciate it. We do feel very good about the year. As Chris noted, we all know what the headwinds are out there and we are dealing with those and staying very close to our suppliers and our customers as we're working through these things. These pendulums tend to go back and forth and part of our job is to work with our customers and try to even those things out as best we can. But long term over time, clearly we expect to grow our top line reasonably aggressively and grow our profitability even faster. Over time, we expect our gross profit and our gross margins to continue to build. We're not going to give specific numbers, but we expect improvement in all those areas. And again, thanks for the question.
Paul Luber
Thank you, Chris and Jay. Could you add a pinch of color You know, you got to the comment of headwinds and tailwinds, more importantly on the headwinds. You know, I know there's labor, inflationary pressures, there's material pressures, but is that the driver or is it competitive market conditions at the customer level or the need to be extra competitive to win new business? Or can you put a little flavor on that finally?
Jay
Yeah, you know, I'd say one of the significant headwinds is, believe it or not, as the global supply chain starts to ease, and really if we look back 12 to 18 months, it is quite a bit better now than it was before. As we've seen that ease, our customers are more comfortable with their inventory, and in some cases they have pushed orders out because they're not as concerned about the inventory because we're performing better, which makes for an interesting dynamic in the market. There's also concerns, of course, as the Fed has been pretty aggressive about taking interest rates up, about whether we're going to really see a hard landing or a softer landing. As we see this, by the way, we kind of anticipate that that pendulum, as it goes back and we've seen business push out. We expect that that will come back, of course, and we'll get back to normal run rates in terms of business. Our customers, for the most part, tend to be a little more independent, if you will, of a lot of the regular market or economic fluctuations because they're in the defense space or because in their medical space. We expect things to normalize out a little bit here this year. And, look, we're all anticipating and, well, we'll say we're planning for a harder landing and hoping for a softer landing, if you will.
Paul Luber
Got it. Thank you. And one final question. You know, here we sit two weeks before the end of Q1. What do you guys think? give us a little sense of how Q1 is tracking at your end and, you know, maybe relative to Q4, top line run rate, margin, and alike?
Jay
Yeah, we won't comment specifically on Q1 at this point, you know, partly because obviously we're right in the middle of it. And like most businesses, the last month of each quarter is pretty busy. So we won't comment necessarily on Q1, but we do expect that we will have a solid year this year overall, and we really like our strategic plan going forward over the next six years. Got it. Thank you, gentlemen. Thank you, Paul. Appreciate it.
Operator
Thank you. Once again, if there are any remaining questions or comments, please press star 1 on your phone at this time. Okay. There appear to be no further questions in queue at this time, so I'll hand it back to management for any closing remarks they may have.
Jay
