Steve Downing
Thank you, Josh. For the second quarter of 2024, the company reported net sales of $572.9 million compared to net sales of $583.5 million in the second quarter of last year. For the second quarter of 2024, light vehicle production in North America, Europe and Japan and Korea declined by 3% compared to the second quarter of last year.
During the second quarter of 2024, light vehicle production weakened in most of our primary markets. In fact, the quarter began with sales coming close to forecast for both April and May, but then saw a significant change in June that left us well below our forecast for the quarter.
In total, the company's revenue for the second quarter of 2024 fell short of our beginning of quarter forecast by approximately $50 million, with the biggest impact coming from expected shipments to some of our largest customers.
As we look to the second half of 2024, light vehicle production forecast continues to show weakness versus prior year performance but we expect to return to meaningful outgrowth versus the underlying market.
For the second quarter of 2024, the gross margin was 32.9% compared to a gross margin of 33.1% for the second quarter of last year. The second quarter of 2024 gross margin was primarily impacted by sales levels that were well below our forecast for the quarter, and slightly lower than prior year levels.
Additionally, unfavorable product mix resulted from lower-than-expected shipment levels with Full Display Mirror unit shipments and exterior mirror unit shipments being the most affected. Unfortunately, the lower sales levels and weak product mix more than offset the positive impact of purchasing cost reductions for the quarter.
While our material cost reductions are in line with our estimates for 2024, our gross margin recovery plan for the year is partially dependent on sales growth and product mix improvements that did not materialize during the second quarter.
Given our historical contribution margins on incremental sales, we believe that our gross margins would have been in line with our overall plan for 2024 had revenue been close to our forecast. Overall, we are very pleased with our progress on the margin recovery plan that we estimated would take until the end of 2024 to complete.
While the gross margin for the second quarter did not meet our expectations, we continue to believe that we have the right plan and team to execute our full gross margin recovery plan.
Operating expenses during the second quarter of 2024 increased by 12% to $73.7 million compared to operating expenses of $65.8 million in second quarter of last year. Operating expenses increased quarter-over-quarter, primarily due to staffing and engineering related professional fees.
Our operating expenses are trending in line with our expectations for the full year, with increases primarily focused on R&D and launches of new programs and products. Operating expenses, especially R&D expenses, are expected to continue at the current pace for the rest of this year as we continue to invest in innovative products and technologies, new business awards and VA/VE initiatives for cost optimization of our bill of materials.
Income from operations for the second quarter of 2024 was $114.9 million compared to income from operations of $127.3 million for the second quarter of last year. Other income swung to a loss of $13.5 million for the second quarter of 2024 compared to income of $1.3 million in the second quarter of last year. The change was primarily driven by noncash losses of $18.3 million, resulting from mark-to-market adjustments and other market adjustments of certain holdings within the company's tech investment portfolio, which were partially offset by interest income.
During the second quarter of 2024, the company had an effective tax rate of 15.1%, which was primarily driven by the benefit of the foreign-derived intangible income deduction. Net income for the second quarter of 2024 was $86 million compared to net income of $109.2 million for the second quarter of last year. The decrease in net income for the second quarter was driven by lower net sales and income from operations compared to the second quarter of last year as well as the previously mentioned changes and other income.
Earnings per diluted share for the second quarter of 2024 were $0.37 compared to earnings per diluted share of $0.47 for the second quarter of 2023. Earnings per diluted share for the second quarter of 2024 were impacted by the lower net sales and operating income as well as the previously mentioned changes in other income for the quarter.
I'll now hand the call over to Kevin for some further financial details.
Kevin Nash
Thanks, Steve. Automotive net sales in the second quarter of 2024 were $559.3 million compared to $574.1 million in the second quarter of last year. Auto-dimming mirror unit shipments decreased by 6% during the second quarter of 2024 compared to the second quarter of last year.
Other net sales in the second quarter of 2024 were $13.6 million compared to $9.4 million in the second quarter of last year. This was driven by a $2.9 million increase in dimmable aircraft window sales and a $1.3 million increase in fire protection sales compared to the second quarter of last year.
Looking at share repurchases. During the second quarter, we repurchased 1.4 million shares of common stock at an average price of $34.43 per share. And as of June 30, 2024, the company has approximately 13.2 million shares remaining available for repurchase from the previously announced plan.
We remain committed to repurchase additional shares in support of our capital allocation strategy, but share repurchases will vary from time to time and will take into account macroeconomic issues, market trends and other factors that we deem appropriate.
Looking at the balance sheet. The balance sheet comparisons mentioned today are as of June 30, 2024 as compared to December 31 of 2023. Cash and cash equivalents were $260.2 million compared to $226.4 million. Short-term and long-term investments combined were $323.6 million, up from $299.1 million, which includes fixed income investments as well as the company's equity and cost method investments.
Accounts receivable was $306.6 million, down from $321.8 million due to the timing of sales within the quarter. Inventories were $463.5 million, up from $402.5 million and accounts payable increased to $206 million from $184.4 million.
Looking at preliminary cash flow items for the quarter. Second quarter 2024 cash flow from operations was $129.3 million, up from $120.9 million in the second quarter of last year. And year-to-date cash flow from operations was $259.1 million, compared to $241.8 million for calendar year 2023.
Capital expenditures for the second quarter were $31.8 million, compared with $47.5 million for the second quarter of last year. And year-to-date capital expenditures were $63.6 million, compared to $90.3 million for calendar year 2023. And depreciation and amortization for the second quarter was $24 million, compared with $24.8 million for the second quarter of 2023. And year-to-date D&A was $47.9 million, compared with $48.9 million for year-to-date 2023.
I'll now hand the call over to Neil for a product update.
Neil Boehm
Thank you, Kevin. I'd like the first quarter of 2024, the second quarter was an extremely busy launch quarter with 32 net new nameplate launches of our interior and exterior auto dimming mirrors and electronic features. Over 65% of these net launches were advanced feature launches with Full Display Mirror, HomeLink and outside auto dimming mirrors leading the way. As we look forward at the third quarter, we anticipate that this heavy launch rate will continue.
Now for a Full Display Mirror update. We're excited to announce that during the second quarter, we began shipping Full Display Mirror to three new OEM customers, bringing our total to 19. We're now shipping Full Display Mirror for the Acura ZDX, the Citroën Berlingo, and the Peugeot Partner. The addition of these OEM customers helps to further demonstrate the global appeal of this technology as well as its acceptance on different vehicle architectures.
In addition to the new OEM customer launches, we continue to see great growth and expansion of our technology at our existing customers. We are currently shipping Full Display Mirror on over 115 nameplates globally. And despite the impacts of the second quarter, we're still on track to achieve our 2024 FDM unit shipment guidance of shipping an incremental 500,000 FDM units above the 2023 unit shipments. The first half of 2024 has been extremely busy, as we've launched more projects than ever before. We're excited about the continued growth we're seeing with our technologies and appreciate all the hard work and dedication that team at Gentex is putting in to ensure we execute flawlessly.
Also, while we're launching a lot of products and technologies, we continue to evaluate opportunities to reduce the bill of materials on existing programs as well as execute the VA/VE launches we are currently having in process. These changes are critical for our margin recovery and stabilization plan as we move into 2025 and beyond.
I'll now hand the call back over to Steve for guidance and closing remarks.
Steve Downing
Thanks, Neil. The company's current forecast for light vehicle production for the third quarter of 2024 and full years 2024 and 2025 are based on the mid-July 2024 S&P Global Mobility forecast for light vehicle production in North America, Europe, Japan, Korea and China. Light vehicle production in these markets is expected to decrease by approximately 5% for the third quarter of 2024 versus the same quarter last year.
For calendar year 2024, light vehicle production in these markets is now forecasted to decline by approximately 2% when compared with light vehicle production in calendar year 2023. Light vehicle production for calendar year 2025 is forecasted to increase by 2% versus the calendar year 2024 forecast in these markets.
Based on this light vehicle production forecast and actual results for the first six months of 2024, we are making certain changes to our previously provided guidance for calendar year '24 as follows. Revenue for the year is expected to be between $2.4 billion and $2.5 billion. Gross margins for the year are expected to be between 34% and 34.5%. Operating expenses are still expected to be between $295 million and $305 million.
Our estimated annual tax rate is forecasted to be between 15% and 16%. Capital expenditures are expected to be between $175 million and $200 million. And depreciation and amortization is forecasted to be between $95 million and $100 million. Additionally, based on the company's updated forecast for light vehicle production for calendar year 2025, as well as year-to-date actual results for calendar year '24, the company is updating calendar year '25 revenue estimates to be approximately $2.6 billion to $2.7 billion. The company continues to be on pace for record revenue in '24 and '25 despite the recent changes to light vehicle production environment, vehicle mix and regional mix that impacted our performance in the second quarter.
Additionally, tremendous work has been accomplished on our gross margin improvement plan despite the temporary step back during the second quarter of this year. We fully expect to achieve our ultimate goal of a 35% to 36% margin for the company, even if there is a slight delay in achieving those results. Given the market conditions, we have adjusted our estimates for '24 and '25 based on the impact of the second quarter of this year, but we continue to forecast strong growth and profitability, as we head into the second half of this year and prepare for 2025.
That completes our prepared comments for today, and we can now proceed to questions.
Question-and-Answer Session
Operator
[Operator Instructions] Our first question comes from the line of Luke Junk of Baird. Your line is now open.
Luke Junk
Good morning, everyone. Thanks for taking the question. Just start with on the guidance, Steve, Hoping you could just square some of your expectations in the back half of the year. On top line, it looks like you're essentially taking the 2Q miss versus your expectations out of the revenue guidance. Can you just maybe talk about what you're seeing in July thus far and in schedules more broadly relative to how you're guiding the back half both overall sales and then the mix impacts to gross margin with demand as well. Thank you.
Steve Downing
Yeah, thanks, Luke. Well, one of the things that definitely I'll start kind of with the Q2 impact and we referenced in our prepared comments that a lot of the shortfall that happened in the quarter, almost 60%, 70% of it was in June, pretty unexpected. When you look at the data that you even put together in your report about what happened in June from a production standpoint, a lot of our largest customers, so GM, Volkswagen, Toyota, they were very significantly impacted in the month. If you look further down that list, other large customers, Hyundai, Kia, BMW, Stellantis. These were all pretty significant customers for us that faced some serious headwinds in June. They were very different. The actual orders were very different than the releases coming into the quarter.
If we look out now in the second half, we look at the same OEMs expectations of their production levels and take rates of our products and some of the new launches that Neil referenced, we continue to see a lot of strength in the back half of this year. So taking into account the 5% drop in production for the third quarter and the fourth quarter forecast for light vehicle production is still showing down kind of 2% to 3% across the board. But we look we look at that and at what our take rates are, where our forecast and releases show, we're still seeing a pretty significant outperformance in the back half of this year. So, we're taking a very hard look at all that release information the customer data, but we still believe we're going to get back to that strong outperformance in the back half.
Luke Junk
And then similarly, could you maybe talk about line of sight to ramping FDM volumes, specifically in the back half? I appreciate the confirmation of still 500,000 incremental units for the year overall, especially thinking about new launches to the extent you mentioned that these are already live. Should we think of those as really already in flight at this point, which would reduce the launch risk? Or is there still some potential movement on timing, which could impact FDM, specifically?
Steve Downing
No. If you look at the launch side, pretty much everything stayed on time during this process. I think the single biggest risk factor is what's happened macro we -- and when it comes to FDM is what's happening macro economically and as the trim level forecast that an OEM puts out, an expectation of take rates for a high-end product like an FDM are those going to hold, given the interest rate environment.
So far, we haven't seen a drastic change from any of our customers in terms of take rates of FDM. In fact, I'd say, over the last 18 months, the trend has been slightly better than forecasted take rates on FDM. This one that obviously impacted June was primarily driven by overall production, not really about changes in take rates.
Luke Junk
Got it. And then maybe for Kevin, just relative to how this all flows through to EPS. How should we think about other income in the back half of the year? I appreciate start to predict some of these market-related things. But at a high level, should we be still thinking there's some mark-to-market risk that could offset underlying interest income and just any way to better calibrate that piece of the P&L? Thank you.
Kevin Nash
Yes. I think most the impact from mark-to-market adjustments has been realized. If you look at -- we have a public company holdings, that I think that are fairly discounted at this point. We will have some of our tech investments that will be ongoing offsets to our other income. But that should be -- we would expect those to be about $2 million per quarter net income going forward, if you look at our fixed income portfolio, offset by the ongoing tech losses. So that's kind of where $1 million to $2 million of income in the back half of the year per quarter outside of mark-to-market, but I think that, that should be mostly realized at this point.
Steve Downing
Yes. Most of the risk out of the portfolio has already been expensed in the second quarter.
Luke Junk
I’ll leave it there. Thank you.
Operator
Thank you. One moment for next question. Our next question comes from the line of Josh Nichols of B. Riley. Your line is now open.
Josh Nichols
Yes, thanks for taking my question. I wanted to kind of touch on one thing and you talked about you're still on track to kind of hit the targets for this year, despite some cuts to the light vehicle production forecasted. You've been seeing more and more take rates and new customers, particularly in like larger OEMs and stuff that's more midstream as opposed to just higher end than what we've seen historically. What's your expectation longer term for FDM? And how do you think about the addressable market as it becomes more mainstream and not just a higher level product offering and how that could kind of supplement growth, not just this year, but longer term, over the next two, three years?
Steve Downing
Yes, Josh, that's an excellent point and a great question. I think one thing is for sure, the launches, especially this quarter, you start talking about volume OEMs introducing this product. They're not going to be at the same take rates as a higher-end OEM or a luxury vehicle or even trucks and SUVs. However, it starts to open the door for much higher volume opportunities by hitting the volume brands. And so very exciting, we knew this was coming. Obviously, we've been working on it for quite some time to get these vehicles launched.
The one thing that's interesting, and I'd say that's probably the most favorable part of FDM is the fact that it doesn't really have a geographical bias. A lot of our products are focused on certain markets, whether it's HomeLink or other features that are very specific to an industry or region. FDM is really a globally accepted product. And so it opens up a lot of opportunity for us. We do believe over the next several years, the FDM will continue to be a tailwind to our growth story.
Josh Nichols
And then you're also working on some other technology offerings. You talked a lot more at your Investor Day. Just curious like your thoughts about what the progress the company has been making in terms of driver monitoring, right? I think at least one OEM was expected to launch at some point this year, dimmable glass longer term and how that's trending and what the expectations are as we kind of continue to think beyond the current year?
Neil Boehm
Sure, absolutely. Yes, we're still on target for this calendar year with an OEM on driver monitoring and then into 2025 and 2026, there are some additional projects that are in launch as well. So we're seeing some good momentum, some good progress and using our geographic real estate in the vehicle to be able to execute that, so great momentum there.
Large dimming devices, is moving forward really well. We've talked pretty openly in the past about a lot of technical challenges and issues, and the push to get there. We're making really good progress there. And I think that in the next couple of years, we'll be excited to talk about where we can see that getting deployed and executed.
And we're also -- one of the things we talked about at CES this year and showed a lot of demonstrations on is large dimmable visors. Great momentum from CES, a lot of customer interest in that product using dimming technology, right, that we've been working on and developed and the processes that we've been working on even with larger devices to help deploy visors to the vehicle.
So we're excited about where it is. There's still some technical challenges and hurdles like there always are, and that's why it's hard to do and why to be successful at it, we solve the problems will give us an advantage. So we're excited about where they can lead us in the next couple of years.
Josh Nichols
And then last question for me, just a follow-up. Just the driver monitoring is more near term. I'm just kind of curious, when you look at the market opportunity there, even if it's just in Europe where there's like different regulation as that's likely to expedite adoption relative to some other regions. What's your thoughts on the opportunity for how big that product offering could be if we look a few years down the line for the company? Is it going to be a material growth driver? I'm just curious how you think about that driving monitoring market?
Steve Downing
Yes. I think it has the opportunity to be material to the overall growth of the business. The beginning, if it's a baseline feature set, it will be slightly -- it will be below corporate average margin profile, because it is more competitive product, but the revenue dollars are definitely significant and can and will really, over the next few years, provide some tailwind to our growth story.
Josh Nichols
Appreciate. Thank you. I’ll hop back in the queue.
Steve Downing
Thanks Josh.
Operator
Thank you. One moment for next question. Our next question comes from the line of Ryan Brinkman of JPMorgan. Your line is now open.
Ryan Brinkman
Hi. Great. Thanks for taking my question. I was hoping you could elaborate a little more on some of the customer or vehicle segment or product mix headwinds you based during the quarter that contributed to the softer revenue than one might have expected, just looking at the headline production numbers.
I know of the things that changed the most during the quarter was lower production of battery electric vehicles. So, curious if that might have been a driver? And then what gives you confidence that maybe some of these headwinds might be more temporal in nature when you look at the full year?
Steve Downing
Yes. If you look, our primary headwind was really driven by some of our largest customers were very impacted in the month of June. And in fact, what the spare part of the quarter was in April and May, those same customers were absolutely hitting their numbers are very close to their numbers. So, what happened in June was very unusual in terms of the impact was, how severe, how quickly?
And then obviously, the million-dollar question is how long lasting are those impacts? Are they permanent trends? Were they one-time adjustments? From everything we're seeing, right, and I always hesitate to be optimistic or after something like that happens. But based on what we're seeing, it seems as though production will go back to pretty much an ordinary course and the data so far in July also suggest that.
Right now, as we sit here at this point, July is off to the start we had expected. We're right in line with where we expect the month to come out. So, whatever happened in June definitely appears to be at least at this stage, to be a one-time event.
One of the things we are watching, though, is that those OEMs that were most impacted and that affected us the most, we're making sure that we're keeping an eye on releases, take rates, looking at the data as it rolls out to make sure if we see anything start to happen or repeat that we can adjust quicker to those changes than what we were able to in June.
Ryan Brinkman
That’s very helpful. Thanks. And then lastly, could you just maybe provide an update on some of the smart home fire protection products and strategy that you talked about at CES earlier this year. I know you were looking to maybe sign one of the big box retailers some point during the year, maybe this summer. Any kind of update there?
Neil Boehm
I'll give you a quick update related to the product launch. So, the initial target was launching in the last half of -- in Q3 here. Right now, we're looking at the first part of Q4 is when the launch will actually go.
We've had some development challenges in some of the testing on some of the features that we're working through right now and should be ready to go in the middle of Q4 to actually go to production.
Ryan Brinkman
Great. Thank you.
Operator
Thank you. Our next question comes from the line of James Picariello of BNP Paribas. Your line is now open.
James Picariello
Hey, good morning everybody. I wanted to ask about your base interior mirror volumes. And look, your largest customer is Toyota as a percentage of sales, they just announced last night that their global production August through October was going to be down 2% year-over-year.
I'm just curious, based on the timing lead lag between your sourcing with a key OEM customer like that, is it possible that you've already experienced that type of forward-looking decline and that's showing up in your weak first half volume shipments?
Steve Downing
Yes, I would say you're spot on. If you're talking about planned production reductions or volumes from an OEM perspective happening starting in July or August, more than likely given the lead-times, especially with the international shipment piece, we're going to see a lot of that play out four to eight weeks in advance of when an OEM actually experiences those pullbacks.
So, it is highly likely that what we experienced in June was a leading indicator of some pullbacks from certain OEMs in the second half of this year.
James Picariello
And just to follow up on this and to get your perspective, again, going back the base or not base mirror, but your interior mirror shipments, right, down 5% through the first half year-over-year. Industry production, global LVT has not been down 5%. We obviously covered the Toyota dynamic. But yes, just what is going on in the first half volume trends based on your customer mix? I mean, I imagine your total customer mix isn't right, I mean, we could track it. It's not down 5%. So yeah, what's truly happening here? Thanks.
Kevin Nash
Well, if you remember, when we talked about first quarter results, there was a couple of key Detroit automakers that essentially halted production for the entire first quarter and so I mean you're having a little bit of that carry over into the second quarter as they have heavy dealer inventories that are still carrying through. But we know that with our vehicle mix and where we're highly contented North America, we know that growth is coming from FDM. So you're not necessarily going to see unit growth in the North American market. It's going to be content growth, and that's how we grow the top line. So it's nothing more than seeing specific OEMs having overweight production flows as they try to manage their inventory.
Steven Downing
Well, I think regional mix is one of the comments we made at the end of the prepared comments, and that's an important one to look at. If you look at Q2 on a year-over-year basis, Europe was down 5%. Japan and Korea was down 4.5%. And so if you look at our primary markets, right, being Europe, North America, Japan, Korea, so North America was relatively flat in total production volume. But you look at the weighted average of the other two-thirds that -- of our primary markets being down basically 5%. That was the single biggest impact. The other one is that, obviously, the business that we do have in China is primarily weighted on base auto-dimming. And that's a very volatile market, much tougher to predict than the rest of the world. And so those are the primary contributors to why you see IEC volumes being down on a year-over-year basis.
James Picariello
Yeah. Make sense. Thank you guys.
Steven Downing
Thanks, James.
Operator
Thank you. We will move on for next question. Our next question comes from the line of John Murphy of Bank of America. Your line is now open.
John Murphy
All right. Good morning, guys. I had questioning, sort of -- similar lines as everybody else. But maybe can you talk about the potential content in take rates on your different products, particularly FDM on EVs versus ICE vehicles? And is sort of this sort of deluge of EV delays or pushdowns on volume to the right something that might impact the business short term or potentially even long term? I'm just trying to understand sort of the delta you see on opportunity between ICE and EVs?
Steven Downing
Yeah. I think if you look at the impact of FDM and you look at our take rates, the interesting part there is that we actually don't have a huge exposure to EVs for FDM. If you look at FDM, trucks, SUVs, a lot of the weight is more towards that side. So we're set up really well in the future as it relates to the impact. The impact of EVs, especially on the Tesla model, is really the OEC impact. So we don't have IEC business at Tesla. We do have a tremendous amount of business on outside auto-dimming mirrors and HomeLink product with Tesla. And so those are kind of your risk factors.
If you look at the rest of the EV manufacturers, especially the traditional OEMs really, our take rates are very similar on EVs on a per technology basis, very similar on EVs versus what we see on ICE vehicles. And so we're not anticipating with this pushout or slowdown and BEV roll out impacting our FDM and that's really why we want to reinforce our outgrowth this year on FDM and picking up the 0.5 million units. We really want to focus on that, because despite some of the trends that are happening between IEC and BEV, we still feel comfortable with our take rates and where FDM trajectory has taken us.
John Murphy
That’s very helpful. And then just a second question. I mean, we're not expecting this, but God forbid, you actually see a continued weak volume environment going forward. And like I said, that's not what we're expecting. I don't think this is really rational, but there's always – you have to consider the risk to the downside. Is there opportunity internally on a micro basis to take cost out or operate more efficiently? I mean, you guys are usually pretty good at that. I'm just curious if there's room there?
Steve Downing
Yeah. And you really start to see it already in the second quarter. We were able to limit amount of overtime we were working during Q2 because of the lower volume side. There's obviously -- if this unfortunately continued, we'd expect to operate in a zero overtime environment, and then obviously be focused on throughput in a more controlled or slower processing platform like that, we would also expect like scrap and yield cost to drop, obviously, free and some of those other expenses are things you can look to optimize when the business slows down slightly.
So there's plenty of opportunity in a lower production environment for us to continue to cost optimize. It's kind of a wild transition, right? If you look at coming out of last year where we're behind almost the entire year, working overtime like crazy, and then finally starting to stabilize throughout the beginning of this year.
June was a weird month. In fact, if you look, there was actually quite a few shipments that we had built for delivery that OEMs didn't pick up at the end of the quarter, which also impacted things. Those are always difficult, right? When OEMs kind of bail towards the end of a quarter or end of a month, it's always a tricky environment.
You have releases you're building to, you build those products, whether they choose to actually pick them up or not is entirely up to them. It's one of the abnormalities of our industry for sure. So we're watching though. And if you look at pretty much since the end of June, most customer behaviors have returned to normal. And so that's why we're cautiously optimistic about what's going to happen and roll out through the second half of this year.
John Murphy
And just one last real quick one. I mean, the stock is down a fair amount here, far below the 34%, 43%, you bought it back in the second quarter. Are you in a blackout period? Can you get more aggressive quickly because the team's like an interesting pullback here?
Steve Downing
Yeah, we are today, but let's just say Monday, we won't be. And honestly, think this is a way over reaction to what just happened especially when you look at our second half guide, which if you take the midpoint of that guide, we're actually implying a 10% growth rate in the back half of this year. So despite, obviously, what happened and some onetime charges on some write-downs, the quarter wasn't that bad. If you actually look at cash generation on the business in Q2, it was better than last year. So we feel really good about where we're at. And whenever the market overreacts, you tend to see us get a little more aggressive.
John Murphy
Okay. Thank you very much guys. Have a great weekend.

Operator
Thank you. One moment for our next question. Our next question comes from the line of Mark Delaney of Goldman Sachs. Your line is now open.
Mark Delaney
Yes. Good morning. Thank you very much for taking my question. The first one is about the second half 2024 revenue guidance. Steve, you mentioned some normalization and customer behavior and you're using customer schedules as an indicator for how you're guiding the second half of the year.
I do want to better understand, given the gap you saw in June between schedules and actual sales, is there any extra conservatism you're using in the second half of this year, some sort of haircutting you're doing relative to those schedules as perhaps a bit more than typical that states in the second half 2024 guidance?
Steve Downing
Yeah, I'd say we modeled this both two fully customer orders and our internal forecast based off of the global forecast. We also look at orders and behavior. In all these scenarios, we keep kind of popping back to the numbers that we provided today for the guide.
And one of the things that's interesting there is, you look at what happened in the month of June. And if you take the rest of the year out of it, so the first six months of the year, that was an abnormality that happened in the month.
It's always interesting when something like this happens. And you can't put your finger on exactly what that issue was, but what we're seeing in terms of customer behavior, releases and light vehicle production forecast for the second half, we truly believe that these numbers are achievable.
Normally, when IHS comes out and they have -- or S&P, sorry, when S&P comes out with their production numbers, we usually are a little more conservative than they are when it shows growth.
I would say we're still doing that. It's not a drastic change. But I would say, normally 1% to 2%, like, is kind of our pessimism that we built into most of their forecast. And so that's pretty consistent with what we're doing in the second half guidance.
Mark Delaney
It's very helpful. Thanks for that. My second question was to better understand the gross margin expansion opportunity. Part of that was coming from improved input costs. I think supply redesign as well as trying to get some improvement from some of your materials and from your suppliers. Maybe you can provide an update on how that's tracking? And have you been affected at all with those efforts by some of this volatility in the industry? Thank you.
Kevin Nash
Yeah. So great question, if you look actually through the quarter, comparing it to last quarter or last year's second quarter, PPV or cost reductions on our input side really performed as we had hoped, kind of like what we had talked about at the beginning the year, it stepped up from the first quarter of this year sequentially and last year.
I mean, it contributed about 150 to 200 basis points to the positive on the gross margin. Unfortunately, with the sales levels the way they were, a lot of that was offset by fixed overhead and the mix weakness that we talked about in the prepared comments as it related to FDM and outside mirrors. So Outside of that, yeah, we're really happy with how the purchase cost reductions have contributed to the margin expansion so far this year.
Mark Delaney
Thank you.
Kevin Nash
Thanks Mark.
Operator
Thank you. One moment for our next question. Our next question comes from the line of David Whiston of Morningstar. Your line is now open.
David Whiston
Thanks. Good morning. It sounds like the pullback was really across the board. It wasn't just in crossovers and just SUVs primarily, correct?
Steve Downing
That's correct.
David Whiston
Okay. It sounds to me too, that your customers really didn't give you any explanation as to what happened in June?
Steve Downing
No. Unfortunately, they only tend to talk to us when they need us to do something that helps them. So yeah, there's -- it's been -- unfortunately, it's very quiet from the OEM side in terms of what happened.
I think personally, if I'm guessing, I'm going to say that there was a there was a lot of -- the inventory on the dealer lots has definitely improved. So I think portion of it that was hey, inventory is there. We're not going to necessarily try shove, as many cars through this environment and kind of right-size.
The other part of it is, I believe, is that probably from an overall raw material side, if you're an OEM, I think they probably had been building inventories given the shortages that happened over the last couple of years and they're probably at a point where they're at a level of like normalcy when it comes to inventory. So I think there's probably a little bit of both things happening that drove this kind of onetime change in shipment.
David Whiston
Okay. So what about the Stellantis news this week that they want to pull back pretty hard in the second half of this year. That doesn't concern you for meeting your revised guidance?
Steve Downing
No, it does. I mean it's one of the things that's honestly -- is partially reflected inside of the of the global light vehicle production data is assuming that there is some pullback with them in the second half this year, how severe that is, comments are tough because if you look at where they're at. I mean, if that's in France, if that's more in Europe for volume vehicles, that's not going to impact us nearly as much as if it's Dodge, Dodge or Chrysler vehicles where we have better content. So the question isn't just about whether or not they're going to pull back. The question is, in what markets and on what vehicles and what platforms.
David Whiston
Okay. And just finally, what drove the aircraft window increase?
Steve Downing
Really, this is them just finally starting to build planes again. The last couple of years have been very little revenue with Boeing especially. Now we're actually into the launches with Airbus as well. So Boeing getting back on their feet in terms of 787 production, a little bit on the 777 side and then the Airbus A350 product as well.
Kevin Nash
And we're in refresh cycles on some of the original planes, so you get a little bit of aftermarket -- not aftermarket, but refurb replacement sales -- placement sales of existing clients.
David Whiston
Okay. Thanks, Kevin.
Kevin Nash
Thank you, David.
Operator
Thank you. One moment for our next question. [Operator Instructions] Our next question comes from the line of Ron Jewsikow of Guggenheim Securities. Your line is now open.
Ron Jewsikow
Good morning. And thanks for taking my question. Maybe just first, I want to clarify the comment that if revenues came in line with your expectations that your gross margins also would have been in line with plan. I guess, we're calculating like a 79% decremental margin versus the first quarter at the gross profit line. So the downside, least optically, does look like there's a bit more than just revenue downside. Any color you can provide on whether the mix or some operational challenges caused by the delay changes to schedules that you saw in June? And I guess, also it sounds like that's normalized into July, but just kind of to repeat that -- that it has.
Steve Downing
Well, I think if you take the $50 million and you look at a contribution margin of 45% to 50% on those incremental sales, you can model out pretty closely. That gets us roughly in line by itself gets us pretty darn close to in line with Q1 gross margin performance. The mix issue that we talked about was really OECs being weaker than expected, and that's not because -- not saying that they were down. And I'm not talking about just the fact that it's down. It's really the percentage of total revenue driven by OEC. So whenever that's a higher percentage, obviously, that's a tailwind. That's what we were expecting was the amount of OEC as a percentage of sales basis being stronger than it was. So that's the one big factor.
The other was the regional mix. If you look at Q2 like I mentioned before, regional mix, right? Europe was down 5%, Japan, Korea was down 4.5%. China was up 7.7%. So given the fact that we're underweight China, and that, that was really the only growth story in the quarter from an LVP standpoint. Obviously, that didn't set up well for us.
If you look at basically, our primary markets, North America, barely up, like up 1% or something. And then Europe and Japan and Korea both down close to 5%. That's really the regional mix issue. And then the product mix issue was OEC being a little light FDM on a percentage of sales being lighter than we expected. Those are the single biggest drivers of the margin weakness.
Ron Jewsikow
Okay. That makes sense. And the drop in tax rate being driven by foreign-derived intangible income, I think that implied as foreign shipments are tracking better at least as a percentage of the business relative to North America. Is there anything you would call out? You called out the China business being up this quarter, at least for base mirror, but anything that's driving the lower tax rate? Or is there kind of other noise in that line?
Kevin Nash
I mean it's a combination of the FDII. We have some discrete benefits from stock-based compensation, R&D tax credits. I mean, the biggest reason that gets us from 21 down to 15 is FDII. I wouldn't say it's heavily outperformed or higher or lower than what we were initially expecting. It just ends up pushing us a little bit lower on the guide and tightens up for the year.
Ron Jewsikow
Okay. And then for FDM launches, I think last quarter, Neil and the team called out one more launch customer this year, you had three this quarter. So is the expectation for any additional customers as we move through this year? Or is there a time line for the next customer that you can provide?
Neil Boehm
Yes. I'm looking here. I think, it looks like -- well, there's a little bit of hesitation on my side because it seems like it's later this year, we'll see an additional one. It might move into the beginning part of next year. So right now, it looks like we'll have an additional one late this year or early 2025 and there could be an additional one in 2025 then as well.
Ron Jewsikow
Thanks. Appreciate that and I’ll hop back in the queue. Thanks for taking the question.
Steve Downing
Thanks, Ron.
