Operator

Good afternoon, everyone, and welcome to the LightPath Technologies fiscal fourth-quarter and full-year 2023 financial results conference call. (Operator Instructions)
Please note this event is being recorded.
At this time, I'd like to turn the conference over to Al Miranda, LightPath's Chief Financial Officer. Please go ahead, Al.

Al Miranda

Thank you. Good afternoon, everyone. Before we get started, I'd like to remind you that during the course of this conference call, the company will be making a number of forward-looking statements that are based on current expectations, involve various risks and uncertainties as discussed in its periodic SEC filings. Although the company believes that the assumptions underlying these statements are reasonable, any of them can be proven to be inaccurate and there can be no assurances that the projected results will be realized.
In addition, references may be made to certain financial measures that are not in accordance with generally accepted accounting principles or GAAP. We refer to these as non-GAAP financial measures. Please refer to our SEC reports and certain of our press releases, which include reconciliations of non-GAAP financial measures.
Sam will begin today's call with an overview of the business and recent developments for the company. I will then review financial results for the quarter and fiscal year. Following our prepared remarks, there will be a formal question-and-answer session.
I would now like to turn the conference over to Sam Rubin, LightPath's President and Chief Executive Officer. Sam?

Sam Rubin

Thank you, Al. Good afternoon to everyone, and welcome to LightPath Technologies' fiscal 2023 fourth-quarter and full-year financial results conference call. Our financial results press release was issued after the market close today and posted on our corporate website.
The fourth quarter was highlighted by significant developments in several of our pillars of growth, which I have been discussing as part of our strategic shift from a component manufacturer to a value-added solutions provider.
To recap our investment, LightPath has been transitioning in the last few years from a pure component manufacturer focused on being the lowest-cost provider to a value-added partner for complete solutions based on optical technology, whose differentiators are mostly technological. Along those lines, we have been focusing on three pillars of growth: imaging solutions such as cameras; growth in new markets such as automotive; and the defense business, all of those driven by our differentiating technologies such as our proprietary materials.
As previously outlined, one pillar of growth revolves around the defense business, increase driven mainly by leveraging our unique infrared materials. To achieve significant growth and market share in that established defense market while still commanding a premium, we're leveraging these exclusive materials for infrared imaging as an entry point into new programs and to become the supplier of choice for infrared optics in the aerospace and defense industry.
One advantage of our materials is that they are an alternative to germanium, the dominant material used in lenses for infrared imaging. The DOD and the White House have identified germanium as a strategic vulnerability within the supply chain. With most of its germanium originating from China and Russia, alternatives are strategically important.
China is the world's largest supplier and recently announced a limit on the exports of gallium and germanium. Our family of chalcogenide glasses, branded as Black Diamond or BD, is the leading alternative for germanium. In anticipation of this possibly happening and to mitigate the potential supply chain liability, we have been working with the DOD and various government agencies to accelerate the qualification and the readiness of our new materials.
Most of this work is funded directly by those agencies. Recently, we announced the US Department of Defense via the Defense Logistics Agency, DLA, will provide the funding necessary to qualify our Black Diamond chalcogenide glass as a substitute for germanium. These materials will be in addition to our BD6 material, which is already fully qualified and field deployed in multiple states.
The DLA funding will be made into two phases. The first phase of $250,000 is earmarked explicitly for three of LightPath's Black Diamond glass. The second phase is expected to cover the remaining six material and totaled approximately $1 million. While new defense contracts can take a significant amount of time to come to fruition, this is a very positive lead indicator to the success of this strategy.
This most recent announcement represents one of multiple fundings we have received to support the development of these materials, totaling over $2 million to date. Those funds are not included in our published backlog numbers.
Currently, we can produce up to 10 tons a year of BD materials. According to different public estimates, the US defense market consumes between 50 to 150 tons of germanium annually for the use in optics alone. Therefore, we are also discussing with the DOD about the possible increase in capacity. Our recent expansion in Orlando facility sets the foundation for such an capacity expansion.
Previously, our BD6 raw material would only be available in the form of finished optical lenses for integrated assemblies in our customers' solutions. However, the time it takes to produce prototypes for new optical designs is one of the challenges to customers looking to make a change and to move away from germanium into new materials.
So to aid the market transition from germanium into the new materials, we will make our most popular glass, BD6, available as raw material. Doing so will help accelerate the transition away from germanium. We are also mindful that export restrictions could have a short-term adverse effect on sales of our products that currently use germanium. And that while the recent developments around our materials support significant growth in that area for LightPath, it does take about two years from the moment the system is redesigned or redesign starts until we see volume production orders.
The second pillar of the growth strategy concerns the adoption of thermal imaging in more applications, and right now, primarily with a focus on automotive. In the last two to three years, we have been working with multiple automotive companies at different levels of the supply chain to design, test, and qualify thermal imaging as an additional safety sensor, primarily for emergency braking system.
Those efforts are often independent of some of the other activities and advancements in automotive such as LiDAR or autonomous vehicle. On May 29, the US Department of Transportation Institute of Highway Safety announced their intention to set a rule mandating emergency braking systems in all new cars and have explicitly called out the gap in performance of those systems at night, naming thermal imaging as a technology that could solve this.
Since this announcement, we have seen increased interest in those solutions and customers looking to possibly deploy those systems to more car models than originally discussed. We are very pleased to have had a two-year head start on many of the other players, time which we used to get field qualified by at least one major car manufacturer and established ourselves as an important player in this field.
Our success in positioning ourselves in this market has led to some of our customers, including and using our name in their proposals as a selling point. And in one case -- at least in one case -- a car manufacturer specifically suggesting to potential vendor that they work with us.
The ASPs are between $20 to $50 per car. This can be transformational to the company. This technology relies on our infrared materials, molding technology, and design and assembly at a subsystem level, all of which really providing a successful proof for our strategy to leverage those technologies to become a solutions provider.
The third pillar of growth, which ties directly into the first two, is our transition from a components manufacturer to provider of engineered solutions based on optical technologies. This transition began a couple of years ago, starting from customized lens assembly, which are what we tend to call LightPath 2.0. Through camera solutions, the first of which is our innovative MANTIS broadband infrared camera, which we announced in December and which is enabling our customers to do things they could not do before.
The latest step in this transition is acquisition of Visimid Technologies. Visimid Technologies does to the back end of the thermal cameras what LightPath has been doing to the front end, the optics. Like LightPath business model of customizing optical assemblies to be used in infrared cameras and then making a large profit in production, Visimid has established itself as the go-to for customizing the electronics and software parts of uncooled infrared cameras.
In fact, Visimid has customized for LightPath the electronics and software of our MANTIS camera. Together with Visimid, LightPath can now extend our offering of customized imaging solutions to include a wholly integrated camera core, where the camera can be customized from its electronics, software, and optics, producing an integrated calibrated camera core for OEM customers to integrate into their system.
With Visimid, our engineered solutions business will now have two distinct offerings: one is the customized solutions, as I just described; the second is offering standard products that are derivatives of such projects, which we can then offer to customers with little to no customization.
An example of that is a new product we announced last week of our high frame rate thermal camera core, something that was developed by Visimid some time ago and now we can offer as a standard product. In short, the Visimid acquisition boost not only our technical capability by adding more discipline such as electronics and software, but also brings with it a portfolio of designs we can commercialize and a pipeline of new project opportunities. The complexity of those opportunities leads to the fact that some of them have a potential of engineering charges of millions of dollars per project.
To conclude, we believe that with our expanded manufacturing facility in Florida, the acquisition of Visimid, and the recent developments in automotive and defense, we are well positioned to take advantage of the larger opportunities that lie ahead and continue transforming the company to grow it substantially above its current size.
Lastly, before I pass the mic over to Al, I would like to commend our team for the ongoing growth of sales in the US. We ended the fiscal year with a 19% growth, 1-9 percent growth in the US sales year over year. While this is not easily evident in the consolidated view due to the sharp decline of sales in China, it is a major achievement in our biggest and most important market. And for that, I want to congratulate the team.
It is the hard work and focus on execution that is positioning LightPath to deliver on the promises of our technology and capability and translate that into growth and shareholder value.
With that in mind, I will now turn the call to our CFO, Al Miranda, to review our fourth-quarter and year-end financial results. Al?

Al Miranda

Thank you, Sam. I'd like to remind everyone that much of the information we're discussing during this call is also included in our press release issued earlier today and in the 10-K for the period. I encourage you to visit our website at lightpath.com to access the documents. I will discuss some of the primary financial performance metrics and provide additional color on them to better assist investors.
On a consolidated basis, revenues for fiscal fourth quarter were $9.7 million compared to $8.9 million in the year-ago period. Sales of infrared products were $5.5 million or 56% of the company's consolidated revenue.
Revenue from precision molded optics or PMO products was $3.2 million or 33% of consolidated revenue. Revenue from specialty products were $1 million or 11% of total company revenue. The increase in infrared products sales was primarily driven by sales of diamond-turned infrared products that is primarily attributable to customers in the defense and industrial market. The decrease in PMO revenue is primarily attributed to a decrease in sales to customers in the telecom and commercial markets, which partially offset by increases in defense and industrial costs.
PMO sales in China continue to be soft across all industries. The increase in specialty optics during the quarter was a result of increased sales of custom visible lens assemblies for the medical industry.
Gross margin in the fourth quarter of fiscal 2023 was approximately $3.1 million, an increase of 10% as compared to approximately $2.8 million in the same period of the prior fiscal year. Total cost of sales was approximately $6.6 million for the fourth quarter of fiscal 2023 compared to approximately $6.1 million for the same period of the prior fiscal year.
Gross margin as a percentage of revenue was 32% for both the fourth quarters of fiscal '23 and fiscal '22. The mix of revenue by product group for the fourth quarter of fiscal '23 was more heavily weighted towards specialty products with less PMO products, which typically have similar margins, while the percentage of infrared products was similar as compared to the same period of the prior fiscal year.
Selling, general and administrative expenses were approximately $3 million for the fourth quarter of fiscal 2023, an increase of approximately $223,000 or 8% as compared to approximately $2.8 million in the same period for the prior fiscal year. The increase in SG&A costs was primarily due to increases in stock compensation and other personnel related costs, including commissions on higher sales. We also incurred costs of approximately $140,000 in the quarter associated with the acquisition of Visimid, which closed in July 2023.
Net loss for the fourth quarter of fiscal 2023 was approximately $809,000 or $0.02 basic and diluted loss per share compared to $1.4 million or $0.05 basic and diluted loss per share for the same quarter of the prior fiscal year. The decrease in net loss for the fourth quarter of fiscal 2023 is primarily due to a favorable difference in the provision for income taxes.
Our EBITDA for the quarter ended June 30 was approximately $72,000 compared to $107,000 for the same period of the prior fiscal year. Decrease in EBITDA in the fourth quarter of fiscal 2023 was primarily attributable to increase in operating expenses, including SG&A and new product development, which were partially offset by higher revenue and gross margin.
Turning now to our fiscal 2023 full-year results. Revenue for the year was $32.9 million, a decrease of approximately $2.6 million or 7% as compared to $35.6 million in the prior fiscal year, driven both by PMO and IR products.
Sales of infrared products were $16.7 million or 51% of the company's consolidated revenue in fiscal 2023. Revenue from PMO products was $13.4 million or 41% of consolidated revenue. Revenue from specialty products was $2.8 million or 8% of total company revenue.
The decrease in infrared product sales was primarily driven by sales of BD6-based molded infrared products, particularly to customers in China, commercial, and industrial markets. These decreases were partially offset by increased revenue from BD6-based products driven by customers in the defense industry Sam mentioned earlier.
Sales of diamond turned infrared products were nearly flat for fiscal years '22 and '23. However, there were shifts in customer mix. The decrease in PMO revenue was primarily attributed to a decrease in sales to customers in the telecom and commercial markets, again, partially offset by increases in defense and industrial costs.
Again, on a fiscal year basis, PMO sales in China continue to be soft across all industries. The increase in specialty optics during the year was a result of increased demand for collimator assemblies and increased sales of custom visible lines of assemblies to the medical industry.
On a global level, revenue has shifted geographically as well as based on product. Year-over-year sales increase in the US by 19% as Sam mentioned earlier. It decreased in China by 55% and decreased in the EU by 27%. The US sales can be attributable to our shift towards defense products and a positive economy.
China decline as similarly twofold, a poor economy and a lack of demand for telecom and industrial products in the country. The EU decline is a little more nuanced. Germany, which is a large market for us, had some mild recession or flat. But the real decline is related to a key customer's annual contract and the year-over-year timing of deliveries, and therefore, more transitory than really the trend that we're seeing in the EU. While the 19% growth in the US might not be easily evident when looking at our consolidated numbers, we do view it as a very important validation of our strategy and execution of the strategy.
Gross margins in fiscal 2023 were approximately $11.1 million, a decrease of 6% as compared to approximately $11.8 million in the prior fiscal year. Total cost of sales was approximately $21.9 million for fiscal 2023 compared to approximately $23.7 million for the prior fiscal year.
Gross margin as a percentage of revenue was 34% for fiscal 2023 compared to 33% for fiscal 2022. The lower revenue level for fiscal 2023 as compared to the prior fiscal year resulted in less contribution towards fixed manufacturing costs. Improving the gross margin at 34% at that lower revenue level reflects the benefit of a number of the operational cost structure improvements that we have been implementing.
Those improvements were partially offset by some elevated costs in the second half of fiscal 2023 as the construction and consolidation of the Orlando facility required us to temporarily outsource certain production process adding to costs.
SG&A costs were approximately $11.4 million for the fiscal 2023, an increase of 2% as compared to approximately $11.2 million in the prior fiscal year. The increase in SG&A for fiscal year 2023 was primarily due to increase in stock compensation, partially due to director retirements that occurred during the second quarter of fiscal 2023, as well as increases in other personnel-related expenses and the Visimid closing cost mentioned.
Net loss for fiscal 2023 was approximately $4 million or $0.13 basic and diluted loss per share compared to $3.5 million or $0.13 basic and diluted loss per share for the prior fiscal year. The increase in net loss for fiscal 2023 as compared to fiscal 2022 is attributed to approximately $927,000 increase in operating result loss from lower revenue and gross margin and increased operating expense.
Our EBITDA for fiscal 2023 was a loss of approximately $355,000 compared to income of $1.2 million for fiscal 2022. The decrease in EBITDA for fiscal year 2023 is primarily attributable to lower revenue gross margin, coupled with increased SG&A expenses and a significant decrease in other income.
As of June 30, 2023, we had working capital of approximately $14.9 million and total cash, cash equivalents and restricted cash were approximately $7.1 million, of which greater than 25% of our cash and cash equivalents was held by our foreign subsidiaries.
During fiscal year 2023, we had a lot of activity around cash management. First and most significantly, we had an oversubscribed equity raise in January, contributing $9.2 million in cash. During the course of the year, we used cash in operations of approximately $2.8 million cash burn.
We invested $3.1 million in capital expenditures and production, plant and equipment predominantly in Orlando. In the normal course of business, we paid down $900,000 in debt. In addition, we used $1 million to pay our debt down and renegotiate to remove onerous terms and conditions from our credit facility with BankUnited. Doing so also included using cash to secure the current loan, but simultaneously enable us to make the subsequent Visimid acquisition, an important strategic move, as Sam mentioned.
The last item of substantive note is the increase in accounts receivable of $1.4 million, which occurred in Q4 and is directly related to $9.7 million of sales for the quarter. Inventory also increased, particularly in whip in the second half of our fiscal year. The increase in AR and inventory contributed to the aforementioned $2.8 million of operating cash flow. Both AR and inventory will stabilize Q1 and Q2 of fiscal 2024.
That said, we feel well positioned on cash for the company's growth in fiscal year 2024. Last week, the increase in backlog during the first nine months of fiscal 2023 was primarily due to several large customer orders, on such orders, $4 million supply agreement with a long-time European customer of precision motion control systems and OEM assemblies. Shipments on these large orders began in the fourth quarter and were shipped during the following 12 to 18 months.
This review of our financial highlights and recent developments concluded. I'll now turn the call over to the operator to begin the question-and-answer session.

Question and Answer Session

Operator

(Operator Instructions)
Brian Kinstlinger, Alliance Global Partners.

Shervin Zand

Hey, guys, this is Shervin on for Brian. Thanks for taking my questions and congrats on a good quarter.

Al Miranda

Thank you.

Shervin Zand

I have a handful of questions, starting off with MANTIS. When do you expect evaluations to end and lead to production decisions? Do you have any greater visibility or confidence when production will start to ramp?

Al Miranda

Yes. So together with the Visimid acquisition now, we're getting a bit of a boost there since some of their customers have interest in MANTIS or even activities around that. So I would say, we expect this fiscal year to ship a couple of hundreds of those, whether in different forms, as Mantis or integrated into other Visimid products.
I think the biggest application we're seeing now in terms of the most significant upside is the fire detection or flame detection, in which is a $2 billion market of optical flame detectors that exist and that MANTIS can add a considerable value there in improving the sensitivity and adding more functionality.
So we're [reservative] about towards teaming up with some of those -- one or more of those vendors of the existing flame detectors. And ideally, one that has a large installed base that can roll out a MANTIS-spaced flame detector quickly. But I would say this year, probably a couple of hundreds.

Shervin Zand

Great. That's awesome to hear. So a similar question, but when it comes to supporting autonomous braking systems, are you working or looking to work directly with Tier 1s or the OEMs? And how long before significant adoption there? I know that Department of Transportation made that announcement, but are you seeing demand start to move as suppliers get ready?

Al Miranda

Yes. Yes, that's a great question. So at this point, we're not working directly with Tier 1. So we're working with integrators to then work with Tier 1 with the place we kind of like to be in terms of our exposure -- our liability exposure, but also sort of the requirements needed from them.
In terms of rolling out, the one company that we've mentioned a couple of times that we are already qualified into them, and we're now in negotiation of a supply agreement with them. And if that is the case, then this year -- this year, meaning this fiscal year, towards the end of it, we'll start seeing already shipments and product sales.

Shervin Zand

Great. Awesome to hear. Last couple of questions. Like you mentioned, government tends to move pretty slow. I know you mentioned one opportunity already within the DOD, but how do you think about the adoption of BD6 and other materials to replace dependence on germanium? Are there other opportunities that are higher in the pipeline that are looking to replace germanium with BD6? And then I might have another follow-up.

Al Miranda

So BD6 being already fully qualified and utilized is already embedded in quite a bit of system. The main interest right now is the new materials. Because since none of the materials is a one-to-one replacement for germanium, you need more than one material, one type of material for that.
Additionally, the new materials also offer advantages compared to germanium. So smaller systems or better performance in extreme temperature conditions arguably are the biggest -- the most important advantages we're seeing. I say that as far as I know, there are, right now, two major systems in the redesign process, with one of them we're expecting to start receiving technical details in the next couple of months, probably. So even though government does move slowly, there are cases where they are trying to accelerate it.

Shervin Zand

Speaking of one to one, you mentioned that right now, you guys have the production capacity of 10 tons per year of the Black Diamond material versus currently 50 to 150 tons of germanium are consumed per year.
Thinking about tons, if you're weighing them both, would this 1 ton of BD replace 1 ton of germanium?

Al Miranda

Pretty much probably. Never thought about it that way. You'd probably need a bit more -- you'd need more of the Black Diamond to replace germanium simply because germanium today has the advantage where the scrap from it can be recycled and regrown into a new germanium, ingot. Where that technology does not exist today for the Black Diamond material.
That is one of the projects we are reviewing with DOD for DOD to finance that because that will offer a substantial reduction in costs of the Black Diamond in the long term. But right now, without that technology, you would need more Black Diamond materials to begin with to achieve the same number of lenses like germanium.

Shervin Zand

That perfectly segues into my next question. In terms of the DLA funding to qualify the other BD products, I know government, again, we've said move slow, how soon are you expecting this first phase of funding? And then once you receive the funding, how long does it take to qualify the other BD products? And are there expanded use cases outside of BD6 with your other BD product?

Al Miranda

Yes, absolutely. So the government does move slowly, like you said. The DLA project has been a year in the making. So it happens to be that it was signed and completed right around the time China made their announcement of germanium, but probably more coincidence than the government suddenly moving quickly.
Based on that, we actually started working on that project already a few months ago. So we have a head start. I would say by the end of this calendar year, meaning in the next three to four months, we expect to be very close to finishing the first phase of the DLA.
Of course, their payment to us is gradual along the way. So we don't need to wait until the end of it to receive the actual dollars. But probably towards Q1 of next calendar year, our fiscal Q3, we will have already -- we will start shipping those materials out to customers to integrate into systems.
That said, the urgency is very clear to a lot of customers, and we are working very closely with customers to enable them to start already the redesigning or designing their systems with those materials now without waiting for the final formal manufacturing readiness, MLM or TRL level that they need.
And we do that by sharing with them the data as we're measuring, as we're going through, as we're starting to produce more material. And within reason, they can usually use that to already finetune or do 80% of their design work. So that once the specs are locked in and everything gets done, they are already far advanced in their redesign process.

Shervin Zand

Great. Thank you for answering all my questions. Really, really excited to all these growth drivers kick in.

Al Miranda

Same here. Absolutely. Good to hear from you. Thank you.

Operator

Glenn Mattson, Ladenburg Thalmann.

Glenn Mattson

Hey, guys. Thanks for taking the question. Sam, curious, the last time we spoke, I believe you kind of had -- you're talking about the export controls of germanium that have been placed by China and just the idea that it hadn't really kicked in yet or whatever. So you're still kind of in a wait-and-see mode to see like what kind of supply you could get or what kind of supply the market could get?
Can you just give us an update on that? And also (technical difficulty), I believe you had some long-term contracts in place, some future contracts on germanium and whatnot to kind of ensure your own supply for at least the medium term. Can you give us an update on that as well? Thank you.

Sam Rubin

Yeah, sure. So to put it into perspective, we consume about 1 ton of germanium a year, which we buy from China, used to be some from Russia from China in the form of what's called the pre-generated blank. So a raw material that is shaped close to the size of the finish lens. And then we process it into a finished lens; coat it; in times, assemble it. But it's part of either components or subsystems that we set.
So even in our own case, we're not completely switched over to BD6 and everything. There are some cases where germanium is still needed. At this point, we started submitting the different export licenses already in mid-July to our vendors in China for the next shipments of germanium.
The end users that then submitted to the government got kicked back a few times, went back and forth, different changes in that until everyone was clear on what information and format they want. And they currently believe that those shipments, which we started working on in mid-July, will ship out of China in mid-November
However, once we received the export license, it is an export license for all shipments related to that order. And since we secure our supply of germanium for one year at a time, that means that at least for the next six months -- six to eight months, we should be able to get shipments from China under those export licenses, assuming we do receive them by mid-November.
I have not yet heard of anyone that has the export license that did not receive or had it denied. But yet I have also not heard of anyone that actually got approved yet. So to the best of my knowledge, no germanium has shipped out of China, at least in the segments of optics and in the people we speak to since it started. Mid-November is the probably the earliest it would be.

Glenn Mattson

Okay. And then you have supply up until about that point or beyond that as of what you have --

Sam Rubin

We actually have enough to keep going beyond that point.

Glenn Mattson

Right. And can you just give investors a sense of like what the backup plan would be if something like that were to get disrupted?

Sam Rubin

Yeah. I mean, to us, it would mean working closer with the customers and it's an incentive to the customer to redesign their systems to use BD6. In a way, longer term, such a disruption is good for us. Short term, it could mean a few million dollars of revenue in a given 12-month period for us.
So probably about four to five, I would guess, something like that. But there's a lot of effort going into and a lot of work going in to ensure that that does not happen. And that there is a backup and that BD6 or Black Diamond work. There is also a stockpile of germanium at Defense Logistics Agency strategic materials, that in the cases of projects that are for the DOD end use, we could tap into that stockpile and purchase material from there.

Glenn Mattson

Right. Okay. Thanks for that. Is there -- I imagine the next round of germanium, if it comes through, would be, which I'm sure will, but if it does, it would be at a higher price, I imagine, right now. So is there a possibility to turn that price increase to pass it along or is that --?

Sam Rubin

We look into places for years, so we're --

Glenn Mattson

Okay.

Sam Rubin

-- at our place given. No change to that. We've seen a little bit of indications of price increase. What we really -- the most disturbing part we're seeing there is that when we ask for a quotation, the validity of the quotation is very short.
So in the past, you would get a quotation and you had a month to order. At that point, the vendors are now giving quotations sometimes with a week validity. One vendor gives it with three days' validity. So to me, it's an indication that they are seeing or expecting volatility in pricing. And they want to indicate -- they want to commit themselves to prices for too long.

Glenn Mattson

Okay, great. That's great color. Al, I'm curious about the gross margin. I've look at it on a sequential basis. Because I know Q3 had the issue where some shipments got pushed out due to the finishing of the facilities' revamp that you were doing.
So one of the reasons that Q3 was viewed as a little lower was because of lower throughput through the facilities and whatnot. And I'm just curious that PMO was flattish or (inaudible) sequentially. So just maybe some color on the sequential rate of change as to why gross margin was (technical difficulty) just a little bit even, given that the facilities are now up and running or maybe there's some time for them to ramp up for sometime. If you can give color, it would be great.

Al Miranda

So most of what we ran into was that although the facility was shut down in Q3, we outsourced a lot of the infrared coating. And that just came with a high price, higher logistic costs which flowed into Q4. So we pushed everything out in Q4. We're nearly caught up from the shortfall in Q3, but we did it at a price and we threw overtime at it as well to catch up with customer orders. So (multiple speakers), but we kind of knew that we were going to spend money to catch up and just satisfying customer delivery dates.

Glenn Mattson

Okay. And then going forward, do you have an expectation on the gross margin side to kind of trend a little better given the move into more specialty products and as those facilities are more mature or whatever? Just what's the thought process for gross margins.

Al Miranda

So margins should continue to tick up at this current Q4 mix. But to be honest, I'd like to see the Q4 mix also become more favorable. So in Q2, I think the mix will look similar. And at in our Q3, I think we'll get a more favorable mix. So higher expectations for margins in Q3 and Q4.

Glenn Mattson

And last for me -- sorry, go ahead.

Al Miranda

It's the overall improvement. And certainly the Orlando construction now being done done will improve our results. But it also a little bit more of a favorable mix in the back half of the year.

Glenn Mattson

Right. And last one for me. On the China side, do you think that you're at a base level now, that that decline is complete? Or are you concerned that there could be more runoff there?

Al Miranda

I thought we were at a base level 12 months ago. So every time I say it can't get worse, somehow -- I mean, you know.

Sam Rubin

Unfortunately, with the --

Al Miranda

You read the news. You read the news. I mean, there was a Bloomberg article today that is predicting complete doom and gloom scenario in China. I find it hard to believe that; I'm rooting for the Chinese government here.

Glenn Mattson

Okay, great. All right. Well, thanks for the color, everybody, and have a good night.

Sam Rubin

Thank you, Glenn.

Operator

Scott Buck, H.C. Wainwright.

Scott Buck

Hi, guys. I appreciate the time. Just kind of one for me at this point or maybe one and half. A follow-up on China. What does China represent now as a percentage of total revenue? And then the second half part of that is, Sam, how do you view China as a longer-term target market?

Sam Rubin

Yes, I'll answer the second part while Al will go to pulling up the data for the first one. I'd say that given that China is -- even with the customers we have left, tends to be the lower end of the scale, meaning they commoditized far, still some telecom there.
It is probably not strategic for us in any significant way. I view China at this point as the investments that we have in manufacturing the facilities that we have on the books that we're using to the most that we can. But strategically, I'm not expecting to see anything significant coming out there other than the regular flow of product to the extent of which we can use that facility.

Scott Buck

Great. I appreciate that. And in terms of what China now represents as a percentage of revenue, do you have like a ballpark?

Al Miranda

Less than 10, Scott.

Scott Buck

Less than 10. Okay. That's it for me, guys. I appreciate it. Thank you and congrats on the quarter.
