Brian Shore
Analyst · Needham & Company
Okay. Thanks a lot, Matt. It's Brian again. A little bit of cold here, so bear with me and my voice. Let's just go to the fourth quarter and compare it to the third quarter. I think it's pretty straightforward if you look at the fourth quarter as a follow-on to the third quarter. The top line in fourth quarter is a little lower. In the fourth quarter, we had the Christmas, New Year's holiday and also the Chinese New Year, and that would kind of explain that.
The pretax and operating profit bottom line, a little bit better actually in the fourth quarter than the third quarter, but still within the range so really, I don't think worthy of getting into a deep analysis of those small differences. Sometimes the analysts ask this question, so in case you do, in the fourth quarter the revenues were flat across the 3 months of the fourth quarter, relatively flat, that would be December, January and February. That's all we're going to talk about in terms of introductory remarks in the fourth quarter.
But I think we should talk about the first quarter because we're in an unusual position where we actually have 10 weeks in the books for the first quarter. We have 13-week quarters. We had 10 weeks in the books in terms of revenues and bookings. And I thought you should know that the run rate during -- over those 10 weeks is $48.8 million. And I just want to be clear what that means. That's not a forecast. I just want to say, again, it's not a forecast.
We take our revenues for those first 10 weeks, we divide it by 10, multiply by 13. So this is kind of a mindless number. There's no opinion or perspective in it and there's no forecast. As who knows, these things could -- maybe it will drop off of the cliff in the last 3 weeks. I don't think so. But all we're talking about is the first 10 weeks, those are facts, and we're happy to report facts to you.
And we thought it's particularly more meaningful. I know sometimes you get involved in these discussions that made me a little bit uncomfortable, when we're doing the quarter, based upon 2 or 3 weeks of the following quarter. And we're trying to extrapolate and I get nervous, so who know what that means. But with 10 weeks in the books and a pretty clear indication as to where we're going, I thought you should know that number.
We had to go back to fiscal year 2012 to see revenues of those kinds. But the other thing you should remember is that if you go find those quarters, the bottom line will probably be better. And why is that? If you go back a few years, we were involved with some things like aerospace startup, negative impact from aerospace startup, right? We also had our plants in Lynnwood and Waterbury and China, which are still operating. So a lot of duplicative costs that are eliminated.
So we kind of have gone through all that difficulty with the refocus of the company. All those kind of drags, if you want to call it, P&L drags are behind us. That's why if you went back to one of those periods and looked to the bottom line, you might expect the bottom line -- I'm talking operating profit, pretax bottom line might even be better on a similar kind of revenue number. So I just thought you should be aware of that.
And so that $48.8 million run rate, it's not really related to aerospace so much. Aerospace continues to grow, but aerospace, probably be a little bit somewhere between $9 million and $10 million in the first quarter. So it's -- aerospace continues to grow. But the -- major impact of that, a significant difference in top line is from electronics.
The bookings in Q1, sometimes we even talk about bookings, not meaningful because we have such lumpy bookings, especially with that big jet company. We sometimes we book a lot all at once, so the bookings would be distorted high in the first quarter, so we're not going to talk about that. I just want to say that analysts -- I hope you don't get too far ahead of us because sometimes we have trouble trying to keep up with them, based on a lot [ph] of information, but this information, I thought you want to know, again, we're talking facts here.
But what's going on, our opinion anyway? There's something that is going on, we think. It's not just kind of -- we don't believe it's a little temporary blip. It seems like there's some significant acceleration in infrastructure buildout, especially in developing and emerging markets. This relates in part to 4G. But a lot of this is in China, the buildout of 4G in China, not all 4G. This helps our -- or impacts our high end digital product line, but also our RF product line, which is our PTFE product line, as well as what we call Mercurywave, our Mercurywave product, which actually has
done quite well. That was introduced, I think, about 3 years ago. And that seeing some nice traction.
As far as our other new products, which are -20 and Meteorwave, I want to make sure I get those right, Meteorwave 1000, 2000. -20 starting to see some revenue traction. Meteorwave, I still like to see that do a little bit better. But I must say that -- maybe this is the broken record part of the story, but there does seem to be a lot of momentum building in the OEM community regarding our new products.
We should talk about that big jet company that we keep talking about. Unfortunately, I still have to call it big jet company, because we haven't gotten the approval yet to mention the name.
A couple of updates from our last quarter conference call, our third quarter conference call. So we entered into an amended purchase agreement with higher volumes. This was contemplated, it's not a surprise. But we just want to let you know that was done. We've also recently received a global RFQ for significantly additional opportunities going out to 2018. At the same time, we've been asked to give a proposal out to 2021.
And if it sounds confusing, it is a little bit, a lot of things moving around, a lot of moving parts, a lot of new opportunities. I mentioned last time, we're working with that jet company on several development projects. Let me stop there for a second, because those are really important for us, because they represent major opportunities.
But also, it's funny because these development projects, there's 3 or 4 of them, are in areas that we had on our, what do you call it, bucket list. These are things you wanted to do for years. But I think realistically, unless we have a partner like this, we probably would struggle to get these things done. With a partner that's quite a bit different and the pace is accelerated and I feel good about it.
These products, although they're being developed in conjunction with this big company, in many cases would be usable by Park with -- for other opportunities. Let's see, yes, I mentioned things moving around. So it's really hard at this point to give you much update on a quantification of the opportunity, so we won't. As I said, we have RFQ for -- through 2018, but a request to give our proposal 2021, a new amended contract. But I guess, if you want my bottom line, maybe you do, I would say that things continue to move in the right direction and be very positive, in terms of the relationship with that big jet company.
And those are all my introductory comments. Pretty brief this time. So operator, I think we're ready for questions.
