David Dunbar

Thank you, Chris. Good morning and welcome to our fiscal third quarter 2026 conference call.

This quarter provides another strong proof point that our strategy, shifting toward faster-growing end markets and increasing new product development, is working. We delivered top-line sales growth of 8%, including organic growth of 6.5%.

Our sales into fast-growing end markets are now above 30% of our total, and new products are expected to add 300 basis points of growth to our 2026 sales results. It is also exciting to see how the mix of our businesses has evolved.

Today, Electronics and our Engineering Technologies business generate about 70% of sales and nearly 80% of total segment profits, both built around custom-engineered solutions for attractive secular markets. That mix shift is what we set out to achieve.

Our Engineering Technologies segment has effectively repositioned itself as a vital partner for space, defense, and aviation customers. We are renaming the segment Standex Aerospace & Defense.

Looking ahead, demand remains healthy. Company-wide book-to-bill was 1.05, and Electronics delivered 1.14, setting us up well as we move into the fourth quarter.

I would like to thank our employees, our executives, and the board of directors for their efforts and continued dedication and support that drove our solid fiscal third quarter 2026 results. Now let's look at the results beginning on slide three.

In the third quarter, sales increased 8.1% year-on-year to $224.6 million, including 6.5% organic growth. Electronics grew 6.8% organically.

New product sales grew approximately 40% to approximately $18.7 million. Sales into fast-growth markets were approximately $69 million, more than 30% of total sales.

We are pleased with the momentum in the business reflected in an overall book-to-bill ratio of 1.05 and within Electronics of 1.14. Adjusted operating margin of 19.7% was up 30 basis points year-on-year.

On March 6th, we completed the divestiture of Federal Industries at an enterprise value of approximately $70 million. This is in line with our portfolio simplification strategy, allowing us to focus our management and capital resources more on fast-growth markets and new product launches.

We used the proceeds to pay down about $62 million of debt, reducing net leverage to 1.9 times. Beginning this quarter, we will report under four operating segments: Electronics, Aerospace & Defense, Scientific, and Engraving & Hydraulics.

The Hydraulics business has been combined with the Engraving business under the Engraving & Hydraulics segment. This divestiture continues a decade of deliberate portfolio shaping toward higher-growth, higher-margin businesses.

In 2014, we operated 16 businesses; today, we're down to five. Following the Amran/Narayan acquisition, Electronics represents more than half of Standex, helping drive the performance you see today.

Our original fiscal year 2026 sales outlook included a full-year contribution from Federal Industries. Even after the Federal divestiture, we still expect fiscal 2026 revenue to increase by about $100 million versus 2025, supported by momentum in new products and fast-growth markets, especially in Electronics and Aerospace & Defense.

I'm pleased with the momentum that we are building in launching new products. We expect to launch more than 15 new products this fiscal year, on top of 16 new products last fiscal year.

We expect new product sales, pro forma for the Federal divestiture, to grow by $24 million to $64 million, adding nearly 300 basis points of organic growth in the year. Our sales into the fast-growing markets such as space, defense, and grid are expected to increase to approximately $270 million, constituting about 30% of our total sales.

On a sequential basis, we expect slightly higher revenue driven by higher contributions from fast-growth end markets and new product sales, and slightly to moderately higher adjusted operating margin due to higher volume and pricing and productivity initiatives, partially offset by growth investments. On a year-on-year basis in fiscal fourth quarter 2026, we expect slightly to moderately higher revenue driven by mid to high single-digit organic growth from growing backlog in fast-growth markets and increased new product sales, partially offset by the revenue impact from the Federal divestiture.

We expect slightly lower adjusted operating margin as organic growth and realization of productivity actions are more than offset by growth investments in capacity expansions, higher medical costs, and increased variable compensation expenses. I will now turn the call over to Ademir to discuss our financial performance in greater detail.

Ademir Sarcevic

Thank you, David, and good morning, everyone. Let's turn to slide four, third quarter 2026 summary.

On a consolidated basis, total revenue increased approximately 8.1% year-on-year to $224.6 million. This reflected organic growth of 6.5%, 0.2% benefit from acquisitions, and 1.4% benefit from foreign currency.

Third quarter 2026 adjusted operating margin increased 30 basis points year-on-year to 19.7%. Adjusted earnings per share increased 13.5% year-on-year to $2.21.

Net cash provided by operating activities was $9 million in the third quarter of fiscal 2026, compared to $9.6 million a year ago. Capital expenditures were $2.7 million compared to $6.1 million a year ago.

As a result, we generated fiscal third quarter free cash flow of $6.3 million, compared to $3.5 million a year ago. Now please turn to slide five, and I will begin to discuss our segment performance and outlook, beginning with Electronics and Aerospace & Defense.

Electronics revenue increased 7.6% year-on-year to a record $119.7 million, driven by organic growth of 6.8% and 0.8% benefit from foreign currency. Organic growth was driven by sales into fast-growth markets and increased new product sales.

Adjusted operating margin of 29.3% in fiscal third quarter 2026 decreased 50 basis points year-on-year due to growth investments, partially offset by higher volume, pricing initiatives, and product mix. Our book-to-bill in fiscal third quarter was 1.14 with orders of approximately $136 million.

This marks the seventh consecutive quarter with book-to-bill near or above one. This consistent streak of book-to-bill around one, targeted capacity expansion within Grid, and acceleration in new product sales adds durability to our growth.

In addition, our monthly orders were over $50 million in both March and April, further indicating robust demand and a runway to a strong fiscal 2027 performance as these orders convert into sales. Sequentially, in fiscal fourth quarter 2026, we expect slightly to moderately higher revenue reflecting higher sales into fast-growth end markets and increased new product sales.

We expect slightly higher adjusted operating margin, primarily due to higher revenue, partially offset by continued growth investments. On a year-on-year basis, we expect high single-digits organic growth.

Aerospace & Defense revenue increased 33.7% to $36.6 million, driven by organic growth of 20.8%, 12.2% benefit from recent McStarlite acquisition, and 0.7% benefit from foreign currency. Organic growth was driven by increased project activity in the commercialization of space end market.

Adjusted operating margin of 18% decreased 60 basis points year-on-year, primarily due to project mix. Sequentially, we expect slightly to moderately higher revenue due to growth in new product sales and more favorable project timing.

We expect slightly to moderately higher adjusted operating margin due to higher volume and realization of productivity initiatives. On a year-on-year basis, we expect double-digits organic growth.

Now please turn to slide six for a discussion of the Scientific and Engraving & Hydraulics segments. Scientific revenue decreased 1.7% to $18 million, primarily due to organic decline from lower demand from academic and research institutions affected by NIH cuts.

Adjusted operating margin of 21.9% decreased 70 basis points year-on-year due to lower sales. Sequentially, we expect slightly higher revenue and similar adjusted operating margin due to product mix.

Engraving & Hydraulics revenue increased 2.2% to $44.8 million, driven by 4% benefit from foreign currency, partially offset by organic decline of 1.8%. The organic decline was driven by general market weakness for hydraulic cylinders.

Adjusted operating margin of 14.3% in fiscal third quarter 2026 increased 210 basis points year-on-year due to higher sales and realization of previously executed restructuring actions. In our next fiscal quarter, on a sequential basis, we expect slightly lower revenue and similar to slightly higher adjusted operating margin from realization of restructuring actions and productivity initiatives.

Next, please turn to slide seven for a summary of Standex's liquidity statistics and capitalization structure. Our current available liquidity is approximately $191 million.

At the end of the third quarter, Standex had net debt of $369.1 million, compared to net debt of $470.4 million at the end of fiscal third quarter 2025. Our net leverage ratio currently stands at 1.9.

We paid down our debt by approximately $62 million during the fiscal third quarter 2026. In fiscal fourth quarter 2026, we expect interest expense between $6.8 million and $7 million.

Standex's long-term debt at the end of fiscal third quarter 2026 was $472.8 million. Cash and cash equivalents totaled $103.7 million.

We declared our 247th quarterly consecutive cash dividend of 34 cents per share, an approximately 6.3% increase year-on-year. In fiscal 2026, we expect capital expenditures between $27 million and $30 million.

I will now turn the call over to David for concluding remarks.

David Dunbar

Thank you, Ademir. Please turn to slide eight.

To summarize, I am very pleased to see the continued organic growth in the third quarter with a book-to-bill ratio of 1.05 when adjusted for the Federal divestiture. Organic growth was driven by our Electronics and Aerospace & Defense segments, which grew 6.8% and 20.8%, respectively.

We will continue to align our organic and inorganic growth investments around secular end markets and new products that expand our presence and deepen our customer relationships. Our acquisition strategy will continue to focus on businesses with accretive margins, exposure to fast-growth markets, and delivery of custom solutions.

With the divestiture of Federal Industries, we realigned our company around four operating segments. We expect fiscal 2026 sales to increase approximately $100 million over fiscal 2025 with margin expansion.

While we remain on course, we will provide an update to our long-term targets on the next earnings call, considering the change in portfolio composition with the Federal Industries divestiture. We will now open the line for questions.

Operator

Thank you, sir. Ladies and gentlemen, if you do have any questions, please press *1 on your telephone keypad.

You will then hear a prompt that your hand has been raised. If you should wish to decline from the polling process, please press * followed by 2.

If you're using a speakerphone, you will need to lift the handset first before pressing any keys. Thank you.

Just one moment, please, for our first question. First, we will hear from Chris Moore at CJS Securities.

Please go ahead, Chris.

Chris Moore

Hey, good morning, guys. Thanks for taking a couple.

David Dunbar

Good morning.

Chris Moore

Good morning. Maybe we can start on the defense opportunity.

You've talked about providing missile nose cone solutions, including nose cones for interceptors, tactical missiles, as well as development hypersonics. Maybe you can just give us a sense for the scale of that opportunity, what kind of orders look like, are there long lead times, just any thoughts there would be really helpful.

David Dunbar

Yeah. There we're talking about within Engineering Technologies.

We serve defense in the magnetics business in Electronics and Engineering Technologies. The Engineering Technologies business provides nose cones out of their Wisconsin facility, and about 15% of the Engineering Technologies, or Aerospace & Defense segment is defense.

Most of that is missiles. There was an opportunity to significantly increase that in the coming years.

We've had discussions with customers and actually with the Under Secretary of Department of Defense asking if we are able to ramp, and they gave us different scenarios. These other scenarios really kind of depend on the government procurement process, passing orders for multi-year commitments to us.

We have received some orders. We expect a nice increase in those sales in 2027, potentially greater if they can unlock the procurement process.

Chris Moore

Got it. I appreciate that.

Maybe just switch gears to Amran/Narayan. Just in terms of the Croatia facility, trying to understand where you are in terms of construction and then just in terms of creating the infrastructure for full market penetration there.

What's a reasonable time frame, and are the competitive dynamics much different in Europe than you see in the US?

David Dunbar

There's a lot in that question. We had no presence in Croatia with that business before.

There was no footprint in Europe. We now have the Croatia site.

It is operating. We made our first products a few weeks ago.

We have customers visiting this month and next to qualify the site. We have external auditors to achieve various certifications, including ISO certifications, that we expect in June.

Shipments are beginning at a kind of a slow rate. We'll begin to ramp much more quickly after those June audits are complete.

We're still confident that our longer-term expectation of at least $60 million in three to five years is reasonable, based on the commitments we have from our current European customers. We are also now building a sales and commercial organization in Europe so we can understand your third question, which is what about the competitive dynamics there.

There is certainly more opportunity than we see. It's a larger market than North America.

It's a much larger market than India. We believe that once we're on the ground with our sales team, with the site there, we will be able to answer that third question for you and figure out what we need to do to take that $60 million expectation higher.

Chris Moore

Just a quick follow, we're a couple of years before you're really accelerating in Europe?

David Dunbar

We ship into Europe from India now. Some of those shipments will begin to come from Europe, will continue to ship from India.

In our FY '27, we think upper single-digit million shipment number is kind of a reasonable expectation. There is upside to that.

How it ramps beyond that, I guess we'll have to report in the coming years, but there certainly is upside because the market is there, and we have the footprint and are building the capacity to grow beyond that.

Chris Moore

Fair enough. I will leave it there.

Appreciate it, guys.

David Dunbar

Thanks, Chris.

Operator

Next question will be from Matt Koranda at ROTH Capital Partners. Please go ahead, Matt.

Matt Koranda

Hey, guys. Good morning.

I guess I just wanted to

David Dunbar

start

Matt Koranda

with the Electronics segment and the order flow. Looks like it's up north of 75% year-on-year.

Wanted to hear a little bit about the drivers of the strength in order flow between Grid and the core magnetics and sensing solutions business.

David Dunbar

Yeah. I'm going to have Ademir ask about the 75%.

I don't see the 75% math. We had a great book-to-bill, 1.14, on growing sales.

We're seeing strong order flow in our core switches business, which for us is a good indication that general industry, certainly in Asia, is picking up. In the quarter the sales were up over 20% in switches.

Relays are strong. Our sales into Grid were up about 20% with a book-to-bill of about 1.1 or something.

We've seen very strong order flow there. It's just kind of a tale of two cities in the industrial world: space, defense, grid, aviation, those businesses are all growing double digits.

General industry in North America and Europe is still fairly slow, and as I said before, general industry in Asia looks like it has really picked up.

Ademir Sarcevic

If I can just add to that, Matt, as we said in our prepared remarks, we had two consecutive months of orders over $50 million for Electronics, which has never happened before. Some of that is clearly the strength we had seen and continue to see in the grid space and some of these fast-growth end markets, but also it's, to David's point, indication that the general industrial markets are stabilizing and we are kind of turning the corner.

Now it takes us a little time to convert those orders into sales, but it makes us pretty bullish about what we're going to see in FY '27 in terms of top-line performance. Again, assuming there is no significant macroeconomic or geopolitical challenges.

Matt Koranda

That's helpful, guys. Thank you.

Then I guess for my second question, wanted to ask a portfolio question. It seems like now that you're under two turns of leverage, you've got plenty of capacity to deploy incremental dollars to M&A.

Just wanted to hear the latest on the funnel, and how you guys are thinking about add-ons to kind of the core segments as you sort of have more capacity at this point in time.

David Dunbar

Yeah. Matt, we like the position we're in now.

We are delighted with the integration of the Amran/Narayan of the Grid business and how that continues to perform, and with our leverage under two now, we're building sizable powder. If you look at the makeup of our business now, 70% of our sales come from engineered components in Engineering Technologies and Electronics, and those are the businesses that serve these fast-growing markets with customized products.

That's the universe where we will explore opportunities. In our funnel, we always have a number of kind of family-owned businesses that are similar to, or privately owned businesses similar to acquisitions we made over the decades at Standex.

With the Grid acquisition, that has also opened up opportunities for us to look at related products to solve bigger problems and become an even more important partner to our customers. In a switchgear, in addition to the instrument transformer, there are other products that support the metering and electrical quality measures of the switchgear itself.

On the Electronics side, there are a lot of opportunities around components and modules. I think we've mentioned in the past, every time a customer works with us for a reed switch-based sensor, a switch, or a relay, they are also working with other suppliers on other components for that same product that are customized to some extent, whether it's capacitors or filters or something like this.

That really opens the aperture for us to explore wider opportunities. For that, we're in discussions with a number of third parties to help us identify targets.

We have an existing funnel. We're working at expanding the funnel with these new opportunities as we fully explore opportunities to expand these engineered components businesses.

Very detailed. We'll leave it there.

Matt Koranda

Thank you, guys.

Operator

Next question will be from Ross Sparenblek at William Blair. Please go ahead, Ross.

Could you unmute your line, please, Ross?

Ross Sparenblek

I was on mute there. Good morning, gentlemen.

David Dunbar

Morning.

Ademir Sarcevic

Hey, Ross.

Ross Sparenblek

Maybe just a level-set on the top-line guide. Are we taking out the first three quarters of Federal, kind of $25 million, or are we leaving that in there, just taking out the fourth quarter?

Ademir Sarcevic

The Federal is out in the fourth quarter guide.

David Dunbar

Yeah.

Ross Sparenblek

Just the fourth. Okay.

Then you guys said Grid was up 20% year-over-year, so that implies what, like a 160 run rate? Pretty healthy growth.

David Dunbar

Yeah. Yes, yeah.

Then

Ross Sparenblek

you guys said what? A book-to-bill of 1.1,

David Dunbar

so

Ross Sparenblek

that means core organic growth, book-to-bill is probably 1.15, up nearly 20%, definitely seeing some momentum?

Ademir Sarcevic

You got your math right.

David Dunbar

Yep.

Ross Sparenblek

That's what I get paid for. Then, can you just give any updates on India and the progress you've seeing with rolling out lean there and driving that capacity?

David Dunbar

I tell you, we had, just a few weeks ago, that, if Vineet's here with us today, he was he was in India a few weeks ago with a very large team for a global Grid capacity expansion Kaizen. We've we have an extensive plan.

We look at global demand, a roll-up from customers around the world by product family. We have a we have a site in Texas, site in India, site in Croatia now.

We're producing in Mexico in our Mexico site and are looking at our global capacity expansion. Our our we do have assumptions that within India, simply with lean, there is another, call it, 15%-plus capacity expansion from lean, which which fuels us, in addition to Mexico and Croatia, through this year.

As we have tech the Texas site coming on next year. Your your question was about India.

We have a have a good handle on the initial, there's unexploited lean opportunities there, 15%-plus capacity.

Ross Sparenblek

Okay. Maybe if I could squeeze one more.

Can you just remind us really quick of the growth investments with Electronics, just the size and the cadence? A couple million bucks in Q4?

Ademir Sarcevic

If you kind of break it down by parts, Ross, most of our growth investments are coming in the Grid business. Obviously, there's some investments we put into Croatia.

That's probably, it's about, call it, 30, 40 basis points if you think about from kind of a margin standpoint of impact right now because obviously shipping as products yet out of Croatia. Then, as David mentioned, and as we're expanding capacity in Houston and Mexico.

You have to hire some people and get some of that rolling before those sites are operational. There's probably another, I would probably tell you, 50, 60 basis points of those investments as well, kind of from a run rate basis standpoint.

Ross Sparenblek

Okay. There's no 232 issues, though.

There were some one-off stipulation regarding Grid. I didn't fully dig into the details.

It just seems like, given the growth in Amran, those margins should have been maybe a little bit higher as staying as in Electronics.

Ademir Sarcevic

Look, we think we're going to continue to expand margins in Electronics, especially as you kind of think about what we are growing is our fast-growth end markets where we are most profitable. We do expect we're going to clip that 30% adjusted operating margin in a near future.

Ross Sparenblek

Perfect. All right.

Thanks a lot, guys.

Ademir Sarcevic

Thanks.

Operator

Next question will be from Mike Shlisky at D.A. Davidson.

Please go ahead, Mike.

Mike Shlisky

Yes. Hi, good morning.

Thanks for taking my questions.

Ademir Sarcevic

Morning, Mike.

Mike Shlisky

Speaking of operating margins, just looking at the results, it's pretty clear that Engraving & Hydraulics are now kind of the lowest of the four, and those are kind of like two different businesses. Can you comment on the plans for those businesses?

You're always trying to hone it a little bit better and a little bit higher, year after year. Is there a potential that those are kind of next to go, I'd say, after Federal?

David Dunbar

As they're strong businesses in their sectors. They're not burning platforms in that sense, it's kind of a question of timing to find the best opportunities for those businesses.

Within Engraving, we have some pretty interesting growth initiatives going on. We talked about making these specialized parts, functional textures, those are ramping up.

The businesses themselves are fundamentally sound. We have some profit improvement projects in both of them.

You look at our history where we've invested in acquisitions. We love the engineered components businesses.

You'll likely see more of that. We have some very good businesses that, Hydraulics and Engraving, they could be fit somewhere else, and we continue to monitor the situation, and we'll make the right decision at the right time.

Mike Shlisky

Okay. In Aerospace, given the organic growth you're seeing now and certainly you've got quite a few opportunities ahead of you, do you see any need to expand capacities there on a greenfield basis?

Ademir Sarcevic

In Aerospace & Defense segment, is that your question, Mike?

Mike Shlisky

Yes. Yeah.

Ademir Sarcevic

Not from a greenfield standpoint, at least not in a near term. We have a bit of a capacity in our sites, but obviously, as that business continues to grow, at some point we might have to look at additional space, but no immediate plans as of right now.

We feel we can service what's coming our way in near term.

David Dunbar

I guess the one caveat to that is, as we mentioned the missile programs, if these missile orders do appear for some of these higher scenarios, then

Ademir Sarcevic

we will

David Dunbar

expand footprint.

Ademir Sarcevic

That's right. That's correct.

Mike Shlisky

Got it.

David Dunbar

We would only do that with a long-term commitment from the customer, and we'd certainly communicate that in a future quarter.

Mike Shlisky

Right. I'd imagine you have an ROC hurdle to beat there, and it wouldn't be any different than you would for Amran or anything else.

David Dunbar

Right, exactly.

Mike Shlisky

Great. Then, it sounds like you're not looking to give us too much guidance yet on fiscal 2027, but can you just comment on the new product menu for 2027?

Do you have as many rolling out next year as you had this year, giving what's in the pipeline? Can you at least expect a halfway decent year from that part of the growth plan?

David Dunbar

If you just step back and take our general growth model, we think we've got these fast-growth markets that continue to grow upper teens, 20% a year, that's like six six points of growth from that. Our new products, we still expect that to add 300 basis points of growth, and then whatever happens with general industry is maybe a tailwind to that.

Just as a high level, I would be thinking in that zone for 2027. In terms I have Vineet here, in terms of numbers of products in 2027,

Ademir Sarcevic

kind of in line with... Yes.

Definitely, Mike. We think the momentum will continue.

Actually, it might even increase because our funnel is increasing internally of new product ideas.

Mike Shlisky

Outstanding. I'll leave it there.

Thank you.

Ademir Sarcevic

Thanks, Mike.

Operator

Ladies and gentlemen, a reminder to please press *1 should you have any questions. Thank you.

Next we will hear from Gary Prestopino at Barrington. Please go ahead, Gary.

Gary Prestopino

Thanks. Good morning, everyone.

David Dunbar

All right. Good morning.

Gary Prestopino

In your new segment breakdown, the Other category, is that legacy Federal before the divestiture? What exactly is in there?

David Dunbar

That is.

Ademir Sarcevic

That's,

David Dunbar

yeah,

Ademir Sarcevic

that's legacy. That's all it is.

Gary Prestopino

Okay. That's all it is.

Okay. With the sale of Federal, was the corporate expense associated with Federal, does that come out of the equation?

I noticed your corporate expense was about $8.6 million this quarter, a step down from last quarter, which was abnormally high. As we're modeling, what kind of number should we be looking at for that corporate expense number?

Ademir Sarcevic

Gary, it's Ademir. We don't really allocate a lot of corporate costs, there's no corporate costs that would go away with Federal.

What's really driving the reduction in a corporate cost for this quarter is some of it is we had slightly lower medical costs versus some of the prior quarters. There was some adjustment to the bonus payouts, and that's basically it.

We do assume that going forward, $9 million to $10 million run rate is probably the right number.

Gary Prestopino

Okay. Then just in terms of your tax rate, because I noticed it was down, I think, this quarter, and obviously a lot of moving parts with the numbers with the sale of Federal, but for Q4, is it looking like it'll be about 24%?

Ademir Sarcevic

Yeah, 24% to 25% is kind of what I would tell you. It's the good estimate.

Gary Prestopino

Okay. Then just last question in terms of what's your growth in Electronics.

Is it all across the board in grid, replacement of grid, data centers, or where are you starting to see abnormal growth?

David Dunbar

Did you say abnormal growth?

Gary Prestopino

Right, yeah. Growth in excess of what you were thinking in terms of

David Dunbar

your

Gary Prestopino

expectations.

David Dunbar

Yeah. The growth drive is certainly a Grid, defense, there's a defense component in, in Electronics.

And, like I I mentioned it earlier, our our our sales of bare switches, reed switches, was up 20%, year-on-year, so that those those go everywhere. It's a sign of a kind of general industry strength primarily in Asia.

And, our yeah, our relay sales are strong, they're driven by kind of test and measurement equipment, similar drivers to the Grid, serving data centers and the equipment that go into data centers. Now, another way to look at it, we have three three businesses in there, as you know.

We've got what we used to call magnetics or our our edge business, which is really a North American business. That was, that that was down in in the quarter year-on-, year-on-year, largely due to some execution issues.

Their book-to-bill was very strong. The detect, the SST business, which is where the switches and sensors are, in, was up upper single digits.

That includes the switch business I I talked about before. Then Grid, of course, which we talked about.

Kind of that triangulates into your your growth question from a couple different angles.

Gary Prestopino

Okay. Thank you.

Operator

At this time, Mr. Dunbar, we have no other questions registered.

Please proceed, sir.

David Dunbar

All right. Thank you.

Appreciate everybody connecting today on this call. We always enjoy reporting on our progress at Standex.

Thank you also to our employees and shareholders for your continued support and contributions. I look forward to speaking with you again in our fiscal fourth quarter call.

Operator

Thank you, sir. Ladies and gentlemen, this does indeed conclude your conference call for today.

Once again, thank you for attending. At this time, we ask that you please disconnect your lines.

Have a good weekend.
