Yes. Thanks, Asiya. Yes. No, we are really proud of the 21% operating margins here in the first quarter. I mean, first quarter typically is the more challenging quarter in the years, given the sequential quarter typical decline we have. And certainly, we always do a good job. But this quarter really, I think, is an outstanding quarter from being able to achieve 21% -- 30% year-over-year and really sequentially about 30%. And that's -- we did 10 acquisitions last year, as you know, and those acquisitions were significantly under our company average.
So when you really pull out and look at the organic conversion on our 6% growth on a year-over-year basis, it's significantly stronger than the 30% that kind of in the reported numbers. And sequentially, kind of the same dynamic with the acquisitions we did in the fourth quarter, being well under the average profitability of the company. Sequentially, that conversion really is well under that 30% kind of in the face. So really strong execution by the team.
I mean the team has done an outstanding job of really -- not only the teams that are growing, but also the teams that are impacted on the negative side. As you know, our industrial market is more challenged and a few other markets as well. And they've just done an outstanding job of controlling costs on the downside as well. So the combination of those 2 really has just turned into a really strong profitability for the company. I mean as we look forward, taking out CIT, I'll talk about that in a second. I would expect that, again, more normal profitability levels on incremental kind of revenue.
If we talk about the 25% longer-term target, I would expect more in that normal range as we kind of get into more of the normal cadence from a pricing cost perspective that we're in right now. But no doubt our teams will continue to manage in a very strong level and do their best to maximize profitability as they have. But I think 25% or so is kind of what I would kind of expect as we kind of go throughout the year.
Now when we layer in CIT, when CIT does close, we expect here by the end of Q2, there's no doubt that business is well under our average company profitability levels currently and there would be some impact on the profitability, on the margins, slightly from an operating margin perspective. And over time, we would certainly work and the team would work as Adam kind of mentioned earlier, to get those back up to the company average. But certainly, in 2024, we would expect some impact on the second half from a profitability perspective from them. But it's a great team, and certainly, we would expect over time to improve upon that.
