Thank you, Jean. Good morning, and thank you for joining our second quarter 2024 earnings call. Overall, we were pleased with our second quarter results. The collective work of the global team over the past year has resulted in improved margins even in a challenging top-line environment.
Our sales came in at $133 million, achieving the high end of the forecast range we provided on last quarter's earnings call and in relating earning press releases with gross margins well, while above forecast forecast range each of our product groups trended as expected, with modest essential growth in connectivity and magnetics from quarter one '24 being offset in part by $1.7 million reduction in power sales.
We are proud of the excellent results achieved by the team on the management side probably this month, we welcome Steve Dawson on to the executive team as the new President of Power Solutions and Protection.
Our power group is going through a pivotal transition with AI and e-mobility as long-term growth drivers. And we are excited to have Steve at the helm as these new markets are locked with new opportunities. We would like to thank Dennis for his almost four decades of dedication to Bel and helping achieve the success we have today.
His commitment and friendship have been display deeply valued by all of us about wish him the best in his retirement, provide an update on our previously announced $25 million stock buyback program. We have continued to make open-market purchases of both classes of stock as of June 30, 2024 a program to to date, purchased a total of $14.2 million, representing 20,600 shares of Class A. common stock of 214,900 shares of Class B common stock.
Lastly, we're pleased for our Class A stock to be added to the Russell 2000 Index. In late June, this is a testament to the overall growth of the company and our recent IR efforts, which aided in the class of stock meeting the eligibility requirements for inclusion in this index for the first time in Bel's history.
And with that, I would now like to turn it over to Lynn. Lynn?
Lynn Hutkin - Vice President of Financial Reporting and Investor Relations, Company Secretary
Thank you, Dan. -- a financial perspective, in summary, we saw continued margin expansion on a lower sales base when looking at Q2 '24 versus Q2 '23, second quarter 2024 sales came in at $133.2 million, representing a 21.1% decline from the second quarter of 2023. The majority of the sales fluctuation was driven by our power and magnetic segments, as I will discuss further, our gross margin increased to 40.1% in Q2 '24 from 32.9% in Q2 '23. And these profitability improvements were largely driven by our Power and Connectivity segments.
Turning to some details at the product group level, Power Solutions and Protection sales for the second quarter of 2024 for $58.6 million, representing a 32.8% decline from Q2 last year. The decline in sales was mainly due to lower sales of our power products used in networking and consumer applications.
On a positive note, we saw continued strength in sales of our rail products, which grew over 40% from Q2 '23, accounting for a $3.2 million increase in sales from Q2 '23. Despite the overall decline in sales. This segment posted a gross margin of 45.7% in the second quarter, reflecting a 1,000 basis points improvement from Q2 '23.
We are reviewing the Q2 gross margin level for this group to be high and estimate approximately half of that basis point improvement in power margins as being driven by the completion of internal initiatives related to procurement, pricing and cost containment and is therefore viewed as sustainable for the balance of the basis point improvement in gross margin versus Q2 '23 relates to items that are either nonrecurring or temporary in nature and should not be factored into a normalized view of gross margin for this segment.
Turning to our Connectivity Solutions Group sales for Q2 '24 came in at $57.8 million, up 5.4% from Q2 '23. The main growth driver within connectivity was within the distribution channel where sales were up $2.5 million as compared to Q2 '23. Sales into commercial air applications amounted to $15.4 million for the quarter and sales into defense applications totaled $12 million for Q2 '24. Each of these levels were consistent with the respective sales from Q2 '23.
The year-over-year increase in sales for this group was despite the divestiture of connectivity check business in June 2023, which previously contributed around $1.5 million per quarter to this segment. The gross margin for this group was 38.9% for the second quarter of 2024, which represents continued improvement from the 37.4% in the second quarter of 2023.
This margin expansion was made possible due to the operational efficiencies achieved through facility consolidations that were completed in 2023, along with implementation of contract renewals on more balanced terms. These favorable margin factors were partially offset by minimum wage increases in Mexico that went into effect in Q1 '24 and the unfavorable impact of FX related to the peso.
Lastly, our Magnetic Solutions Group posted sales of $16.8 million in Q2 '24, representing a 37.3% decrease from Q2 '23. This reduced sales level was generally in line with the expectations discussed on last quarter's earnings call and largely related to lower shipments into a large networking customer as they work through inventory on hand the gross margin for this group was 26.4% for the second quarter of 2024 as compared to 24.6% in the second quarter of 2023.
This improvement in margin was primarily driven by lower fixed overhead costs resulting from the facility consolidations in China completed in late 2023 and favorable FX related to the Chinese renminbi versus Q2 '23. At the consolidated level across all product segments and our backlog of orders was $304 million at June 30, 2024. R&D expenses were $6 million in Q2 '24, a level consistent with Q2 to '23. We expect future quarters to generally be in line with the Q2 '24 expense.
Our selling, general and administrative expenses were $24.1 million or 18.1% of sales, down from $25.1 million in Q2 '23, but up as a percentage of total sales within SG&A, an increase in salaries, fringe benefits and amortization expense were largely offset by lower legal fees.
If you recall, we incurred $1.2 million of legal fees related to the MPS litigation in Q2 '23. And these expenses did not recur in Q2 '24 as there are no unusual items of note contained within SG&A during Q2 '24, we view this level at a level of expenses generally indicative of the anticipated run rate for future quarters in 2024.
Turning to balance sheet and cash flow items. We ended the quarter with $143.8 million in cash and securities, an increase of $16.9 billion from year end. We generated $38.3 million in cash flows from operating activities during the first six months of 2024 and had capital expenditures of $4.3 million.
From an inventory perspective, the downward trend that we experienced over the past several quarters has continued into Q2, reflecting an $8.6 million reduction from year end. The lower inventory levels were primarily seen in the areas of raw materials and finished goods as we continued to work through our own inventory on hand.
I'll now turn the call over to Farouq for additional commentary. Farouq?
Farouq Tuweiq - Chief Financial Officer, Treasurer
Thanks, Lynn. As noted in our last two earnings calls, we anticipate 2024 to be a reset year and our second quarter and first half results were in line with our expectations. We do expect a slight downward shift as we enter the third quarter. As noted in our earnings release based on information available as of today, we expect Q3 '24 sales to be in the range of $118 million to $126 million.
This compares to sales of $159 million in Q3 '23. We believe the following factors are the main drivers of Q3 '24 sales as compared to Q3 '23 at a high level, connectivities projected to grow a bit. Powers are expected to be down approximately $20 million to $25 million with the remaining $10 million to $15 million decline related to magnetics as it has been going through that correction.
Many of the factors contributing to these year-over-year declines in power and magnetics in Q3 '24 compared to Q3 '23 are not new as destocking and networking and distribution had been ongoing factors for the past few quarters. Now there is, however, one new factor this quarter that will impact us beginning in Q3 '24.
One of our China-based former suppliers has recently become subject to trade restrictions applicable to it beginning in the second quarter by executive order of the Biden administration. The team has been diligently working to onboard a replacement supplier and thus expect a few quarters' worth of impact given the work needed ahead.
It is unclear at this time of the ultimate impact of the supplier change, but for purposes of our Q3 '24 guidance, we are assuming a full impact to be on the conservative side. Our sales in Q3 '23 that were supported by this supplier amounted to $4 million. These factors are expected to be partially offset by continued strength of our rail end market, which we anticipate will be up by approximately $2 million as compared to Q3 '23 when bridging Q2 '24 sales to anticipated Q3 '24 sales.
Our power segment is the main driver of the decline. With Q3 sales expected to be down by approximately $9 million due in equal parts to the previously discussed softness in networking sales impacted by our former supplier China-based suppliers discussed and lower volume of shipments out of Europe due to the usual European summer break at our manufacturing sites. And at those of our customers based in the region.
We anticipate modest continued improvement in magnetics in Q3 '24 on a sequential basis from Q2 '24, and this is expected to largely offset the lower ship quarter anticipated in our connectivity segment due primarily to timing of military programs. Turning to our operational initiatives, our team has continued its efforts in maximizing efficiency level at our manufacturing sites globally.
To highlight a few initiatives within our magnetic segment, comprehensive product process and facility cost management projects are ongoing at our new manufacturing facilities to better align our magnetics cost structure with anticipated levels of near slash medium term future demand for these products.
We're also continually exploring other areas of production to better meet customer requirements, including non-China sites. In addition, we had recent efficiency improvements at our Signal Transformer facility in the Dominican Republic.
Shifting to the connectivity Solutions segment, the facility consolidations completed in the US and UK in 2023 have resulted in improved operational efficiencies, contributing to the 150 basis points improvement in this segment from Q2 '23 to Q2 '24 on the restructuring front, the recent initiative to transition manufacturing operations from our Glen Rock Pennsylvania location to other existing sites is on schedule for completion by the end of 2024 anticipated annual cost savings related to these initiatives are expected to be in excess of the initial $1 million estimate.
Shifting over to M&A, the heightened level of activity described in our last earnings call has continued. There is something there's nothing to report here today, but the team is actively evaluating a number of opportunities within our existing product groups in support of our growth strategy consistent with prior quarters will continue to influence those areas within our control, and we remain very optimistic about Bell's future.
I'll now turn the call back over to Dan.
Daniel Bernstein - President, Chief Executive Officer, Director
Thank you Farouq, can we open up the call now to questions, please?
Operator
(Operator Instructions) Bobby Brooks, Northland Capital Markets.
Bobby Brooks - Analyst
Hey, good morning, guys. So, you know, last call, there was a healthy amount of discussion on emerging opportunities, specifically within AI, but also within EV and space. So any color you think would be helpful to hear about that. I understand that these are long sale cycles, but also from my perspective, it seems like stuff within AI is moving quite fast. So, am I right in thinking that those sale cycles could become shorter? Thank you.
Farouq Tuweiq - Chief Financial Officer, Treasurer
Yes, thanks Bobby. I appreciate the question. We've as we said previously, our power segment will be the biggest beneficiary of the AI world. We do see that, obviously, as we are seeing more exciting opportunities in that space as well. One of the things that we have talked about previously is given the high level of complexity and sophistication of our products.
Have they been a I ready call it for the most part. As a result of that, as we think about the networking destocking, there is a little bit of a preference to using some of the product that's in the channel. And so we tend to focus on really in what is the new inbound, whether new opportunities coming in and we're seeing those come in.
But we do expect sequential growth from our AI customers on play as we go through the year and definitely heading into 2025. So we're optimistic about it and we're seeing that. We think it is a real thing, but it will take a while, especially as the channel clears out a little bit and some of our where we're playing and position there takes a toll.
Lynn Hutkin - Vice President of Financial Reporting and Investor Relations, Company Secretary
And Bobby, I can just add on the space side. So revenue there continues to grow. So in Q2, '24, our revenue into space applications was $2.3 million. On a year-to-date basis, it's $4.3 million, and we're still looking at $7 million for an estimate for full year 2024, expecting it to be a little lighter in Q3 and then picking back up in Q4, so $7 million for the full year still sorry.
Bobby Brooks - Analyst
Awesome. Appreciate that color. And then, you know, kind of stepping back a little more on the fourth quarter conference call is you guys listed several growth focused sales initiatives along with, that we've revamped European sales force. So we're several months into those after announcing them.
Curious to hear any early results from it. Any lessons learned or just any color on kind of those growth focused initiatives that you talked about in the fourth quarter conference call?
Daniel Bernstein - President, Chief Executive Officer, Director
Again, I think it's too early to state when we're going to see improvement. But I am very surprised with the sales incentive program that most of the salespeople did receive it very positively. And even though in the first two quarters a majority of them didn't get the compensation bonus because they didn't hit their targets. They still believe that a find to be very beneficial.
So I think this and that they're motivated with this new structure is a really good sign. And with the activity level in Europe, since Sabine came aboard, we are seeing a lot more activity, a lot more quoting and a substantial greater opportunities than we have seen in the past.
Farouq Tuweiq - Chief Financial Officer, Treasurer
And maybe to double-click on that, Bobby as well with all our three regions, U.S., Asia and Europe, I'd say we are seeing some some bright spots in a challenging market, right? So as the markets calm down a little bit things push out of the system, I think that will be what we're looking forward to. But to Dan's point, I think early early signs are optimistic.
Bobby Brooks - Analyst
Got it. And then last one for me. So you guys gave a little a good amount of color on the trade restriction on that Chinese supplier. So I guess one thing that I was kind of wondering if we could double-click on was with the third quarter guidance so you said that that supplier initially was supporting $3 million to $4 million in sales into the consumer end market.
And that the guidance, you know, took a conservative view on that. Does that mean that essentially you're backing out saying that $4 million that you would see in a quarter for from this supplier essentially saying, like all that $4 million goes to zero in this quarter.
Kind of any any more color on that? And just wanted -- how long one so from one, the Biden administration made that executive order to one you found a new supplier, like how long did that take into this new supplier going to be? I'm going to my right to assume.that it's probably going to be, yeah, high -- lower margins or I should say cost more?
Farouq Tuweiq - Chief Financial Officer, Treasurer
Yes. So we are taking a conservative approach. Generally, obviously we kind of take these things pretty pretty aggressively in Q2 that the mandate came out. And in the early days, there was a little bit of confusion what's allowed what's not allowed and working through all that. And we've settled in on is really no new orders, right? So there might be some things left in the inventory side or being shipped over that may be a little bit. We see some uplift there.
But, given our design cycles, as it's not as easy as shifting things over, right, because a lot of these things have to go get retested and requalify. And so once you identify the replacement side of things, right, it's going to take a little bit of time as it goes through the requals or recertification. And that takes different different time lines, if you will.
So as we're going through all that iteration of understanding that we have suppliers identified, I think for but not maybe not everything up but a decent amount. And it becomes a question of how fast you can get them to market requals because there's maybe some dollar spend on the customer side.
So we said let's just kind of take a view of saying we're going to have really no sales of that here in the quarter. And then maybe we can be pleasantly surprised a little bit to the upside, but that's not something we want to set up for. Again, trade restrictions are serious. So I just want to make sure that that we're within bounds on all things.
So it is a little bit of a conservative. So we'll have a better update on that and October call in terms of progress and where we think things will shake out.
Bobby Brooks - Analyst
Fair enough. I like that approach, thank you guys for taking my call.
Farouq Tuweiq - Chief Financial Officer, Treasurer
Thanks, Bobby.
Operator
Theodore O'Neill, Lichfield Health Research.
Theodore O'Neill - Analyst
Thanks very much. Just on the power segment, a little more granularity, if you could. So, I would expect that given we already talked about AI, but in terms of AI, e-mobility, data center, blockchain power conversion, can you give us some more information about how that power segment is doing in those areas?
Farouq Tuweiq - Chief Financial Officer, Treasurer
Yeah, I would say it's really kind of more of the same, right? I mean, the way we tend to think about it is really more simply, anything that influences growth in data centers, whether it be new builds or upgrade cycles, is good for us. And then we also think about, as we think about data, kind of transmission and the whole ecosystem around data, we think that's good.
We've talked about previously our avoidance of the hyperscalers, which is kind of all the news and the headlines these days for various reasons. And we think the hyperscalers are roughly 50% of that market, and we're on the other 50, if you will. But ultimately, we're bullish on that. But right now, there is a little bit of a clear-out of some of the products in the system.
Daniel Bernstein - President, Chief Executive Officer, Director
But we are again, just so you understand when we look at data centers we do a substantial job with Facebook in maybe five years ago, and it was almost a $12 million $15 million customer for us, but the margins were extremely low. And I think our sense for who came aboard, we really tried to focus on margin improvement and realize that top line growth is not the end-all and be-all for us.
So with that, in mind, we really are focused on the niche markets, even though EV are very big market, our niche marketing, EV of school buses, tractors on large equipment. So not going after the Teslas of the world, but really who can we support properly, who can understand our engineering proposition, we offer them.
In the same way, we look at data says we support for one of our big customers in that area is taking on the testing front. The testing equipment that they're using for the ICs are using into data centers. So again, it's anytime electronics goes up there's a lot of areas that we can grow in. And again, we really are focused on areas that we have to be profitable.
Theodore O'Neill - Analyst
Okay. Thanks very much.
Operator
Jim James Ricchiuti, Needham & Co.
James Ricchiuti - Analyst
Thanks. Good morning. I wonder if you could spend a few moments just talking about the pricing environment, just given the weak demand environment, I'm trying to get a better sense of what the gross margins could look like in a more normalized demand environment, whatever that looks like, but just any sense as to what your what you're seeing from folks?
Daniel Bernstein - President, Chief Executive Officer, Director
Theo, I hate to say this on the phone, but to be shocking. I think this is I've been involved for over 40 years and this is the first time in a down market that we haven't seen it very little price pressure. I think everybody is still kind of focused on supply. It's very difficult when you push back, you're always asking for a price decrease at the same time.
So I think each of the past 18 months, the focus hasn't been on pricing at all. It's really been on inventory management. And then if it does cut loose and the lead times to get stretched out than you would have been price increases become available. But again, this is the first time in my memory that there's a down market and we haven't seen any upward price pressures.
Farouq Tuweiq - Chief Financial Officer, Treasurer
You know, remember, Jim, right, obviously as volumes pickup, right in a more healthier environment, you'll get some of those pressures. And that's kind of why we've been doing a lot of the work we have been doing around cost management and the facility work that we have been doing.
The other thing I should say is I think from a mindset perspective and approaching new products and the businesses we're going after in the last call it couple of half years have been lending themselves to a little better potential outcomes. But standpoint, we do expect to see that obviously in different parts of our business. But we're not we're not there yet.
James Ricchiuti - Analyst
Okay, helpful. And what kind of demand are you seeing in the military and commercial aerospace market. I may have missed it. Lynn, did you provide on revenues for commercial aerospace?
Lynn Hutkin - Vice President of Financial Reporting and Investor Relations, Company Secretary
I said so in Q2 '24, commercial aero was $15.4 million. And military with $12 million gathered.
James Ricchiuti - Analyst
Got it. Thank you. Thank you. Sorry about that. I missed it. Just a final question from me. I think you've alluded to or suggested that there's some green shoots out there. And we're hearing that from some other players in the market. But maybe this is a question for you, Dan. As you think about the recovery, how could this recovery look?
Daniel Bernstein - President, Chief Executive Officer, Director
I've been thinking about the recovery for about 18 months, Jim
James Ricchiuti - Analyst
Fair enough. And I guess that was the question. I mean, given your experience in different cycles, what does a cycle look like when we see some signs of recovery? I guess what I'm asking is --
Daniel Bernstein - President, Chief Executive Officer, Director
When is it going to turn around, right?
James Ricchiuti - Analyst
Yes.
Daniel Bernstein - President, Chief Executive Officer, Director
Jim, it's I tell it all the time in our industry, it's always six months. It was six months and you go back to the guys six months. We're in constant contact with Arrow, Avnet, all the major distributors, and we keep asking wins inventory going to be down when you're going to see new orders when you're going to see no and they always come back six months, six months.
And then all of a sudden hit some in a day and they start ordering. So it is I've never seen it to be stretched out this maybe during the recession in '89 was about two years, 2.5 years. But yes, just the you're not hearing anything you see little areas of improvement like aerospace, of course. But overall, just I think it's back to that wait and see type a thing.
James Ricchiuti - Analyst
Yes.
Farouq Tuweiq - Chief Financial Officer, Treasurer
I wish I could be a lot more positive to the bottom line.
James Ricchiuti - Analyst
Yes, no, fair enough. Thank you.

Hendi Susanto, Gabelli Funds.
Hendi Susanto - Analyst
Good morning, Dan, Farouk, and Lynn.
Daniel Bernstein - President, Chief Executive Officer, Director
Good morning.
Hendi Susanto - Analyst
Yeah, so I would like to follow-up Jim's question. So is it another pushback of six months? I think that is my interpretation and I want to confirm that.
Daniel Bernstein - President, Chief Executive Officer, Director
This is the standard answer they give when they don't know. It could be two months. It could be a year. But if you ask anybody, they'll come up with a patent answer, six months. But I don't know if it has any credibility. That's my point. It's just, you know, the checks and the mail kind of line. It's just, you don't, it's just, a line they put out there, but I don't know if you can put any credence in it.
Hendi Susanto - Analyst
And Dan if I may ask further and when the recovery happens do happen that to be somewhat mixed among different products, different end markets? Like do you see, let's say, like like where do you feel it is more negative and where you feel more positive in terms of?
Daniel Bernstein - President, Chief Executive Officer, Director
I think that our model there is really the down markets really hit us in networking more than any other area. Our networking customers.
Hendi Susanto - Analyst
And then how concentrated in networking?
Daniel Bernstein - President, Chief Executive Officer, Director
Networking, which are a lot of our distribution comes, it's distribution, but they go to networking customers also.
Farouq Tuweiq - Chief Financial Officer, Treasurer
Yeah. So I think, can you just, those are obviously our two biggest markets, right? Distribution and networking, and I think both of them are where we're getting hit on.
Hendi Susanto - Analyst
And then are they under-shipping end demand?
Farouq Tuweiq - Chief Financial Officer, Treasurer
Can you expand on that a little bit, I think so.
Hendi Susanto - Analyst
In networking and distribution, are your customers undershipping or shipping like lower than the end demand there?
Farouq Tuweiq - Chief Financial Officer, Treasurer
I would not think that's the case, I think they'll ship to meet demand.
Daniel Bernstein - President, Chief Executive Officer, Director
No, I think I think they're still using the inventory they have to meet demand. So they don't have to so over inventory. They don't have to place new orders into the get the inventory down a lot less.
Farouq Tuweiq - Chief Financial Officer, Treasurer
And what we've looked at is inventory levels, right? So we can have and our view is inventory levels have been coming down pretty significantly. So we do feel and that's why the last couple of quarters I've been saying it's we feel like it's bottomed out and we continue to hold that view.
But when does it get back to a little more regular way patterns? So we tend to focus on inventory levels, but we don't think anybody is they're not sending things that our customers are asking any questions.
Hendi Susanto - Analyst
And then for your internal inventories, I think Bel Fuse has been lowering down and freeing up working capital. How much further should we think about Bel Fuse lowering its internal inventories?
Farouq Tuweiq - Chief Financial Officer, Treasurer
Yeah, I would say, we could probably address that a little bit more with a little healthier sales environment, right? So it's one of those things where we tend to focus a little bit on the terms side of things. We're not quite where we would like to be yet. So that's something we're influencing and trying to influence. I think we've done a pretty decent job at it.
A little bit easier to manage and do that in a more healthier sales environment, which we're not in. So maybe in short, we would like it to be better and we're trying to get to that better and it would be a little bit, I think, easier to manage in a healthy environment.
Hendi Susanto - Analyst
And then Dan and Farouq, I want to ask whether you have any insight into this. There is some conversation that there's sequential improvement in China in automotive and industrial and in IoT. What are the current trends that you are seeing in China?
Farouq Tuweiq - Chief Financial Officer, Treasurer
If I remember, we'd do sell some stuff in China. But generally, that's not our main customer base, right? And I think that's one of the the actually, quite frankly, good things given just the pricing environment the higher level of competition that tends to be more higher volume type business or medium volume.
So it's not kind of our we pick our spots, we're picky and choosy, but were. But I would say those are not kind of things that we overthink about.
Hendi Susanto - Analyst
Okay. And then I may miss this, the sales of e-mobility in Q2. May I ask for that number?
Lynn Hutkin - Vice President of Financial Reporting and Investor Relations, Company Secretary
Sure, so e-mobility sales in Q2 were $4 million.
Hendi Susanto - Analyst
$4 million. And then I assume there is no expedite fee, is that correct?
Lynn Hutkin - Vice President of Financial Reporting and Investor Relations, Company Secretary
There was no expedite fee this quarter, correct.
Hendi Susanto - Analyst
Okay. Yes. Okay. Thank you so much.
Daniel Bernstein - President, Chief Executive Officer, Director

Bobby Brooks.
Bobby Brooks - Analyst
Hey guys, I just want to jump back on and kind of square something away. So in the press release, you guys said on the and at an industry conference in May, I indicated that the consensus view that was indicated that the worst was behind us. Is that in terms of kind of that just on the distribution? Or is that more broadly distribution and networking?
And I guess, like obviously those are kind of to the biggest end markets that you guys serve. But do you guys mostly serve the networking end market through distribution? I just want to kind of make sure I understand that dynamic.
Daniel Bernstein - President, Chief Executive Officer, Director
Yeah, no. Most of our, a good portion of our networking business is direct. I would say probably 75% is direct to the customer for networking. But overall, when you throw in smaller, you know, networking companies, industrial companies, then they go through distribution. So overall distribution represents about 30% of our sales.
Lynn Hutkin - Vice President of Financial Reporting and Investor Relations, Company Secretary
Yes.
Farouq Tuweiq - Chief Financial Officer, Treasurer
And I think maybe your other part of your question, Bobby, the conference reference was really that was a distribution call it focused and a conference that happens once a year. And so that was that specific comment about a conference was on the distribution side.
Bobby Brooks - Analyst
Okay, awesome. Thank you, guys. I'll return to the queue.

Thanks for the guidance on gross margins. I wonder if you could maybe help us a little bit with the OpEx, which has moved around a little bit. You saw a nice uptick in R&D in the quarter. Should we assume that these R&D levels are more normalized?
And any sense as to, on the SG&A side, I assume at these lower levels of revenues, probably not a significant uptick there. Is that a fair way to think about OpEx?
Farouq Tuweiq - Chief Financial Officer, Treasurer
Yeah, I think that that's pretty fair. I mean, the, you know, roughly around, you know, the call that $6 million, $5 million, $6 million R&D is kind of where we think it is. Remember, more R&D goes into power and connectivity side of the business. In terms of SG&A, there is some variability in that as it relates to some outside commissions that we pay and some other co-items.
So we tend to think about it around $25 million. I would say, we are looking to see ways that we can influence SG&A as we just kind of think about the world that we're in. So that's something where we are focused on, if you will, and looking at what's in the art of the possible there. But largely, we kind of guide towards flattish or range-bound, we should say.
