Yes. Thanks for the question, Josh. So factors that will bias results to one into the range or another are multifaceted. They include things like foreign exchange exposure in our big Government Services contracts. We do get paid in local currency, so that's the pound on U.K. SAR. It will be the euro with Irish Coast Guard. So a stronger pound, stronger euro are better for our results and would bias results more to the higher end of the range.
We do have -- I mean, I think it's responsible to note some operational execution, especially on the new contracts, but that's mostly weighted to the near term 2024 and 2025.
Another factor would be supply chain challenges. We've talked about the various supply chain challenges that are impacting the industry today, namely weighted to the S-92. So if there's an improvement in those conditions and we're able to return incremental S-92s into service and generate revenues and cash flow sooner than expected, again, that could bias us more to the higher end of the range.
Of course, you have the overall macro questions, particularly on our Offshore Energy Services business, where the cycle is going to be. That's more, I would think, weighted to later years, though. I think as of now, for the reasons we've discussed, we have a pretty high degree of visibility and conviction in what activity levels are going to look like over the next 2 to 3 years, which, again, we think are quite positive.
So those are some of the various factors just directionally that would bias to the high end of the range or another. We are guiding, and Jennifer summarized on the bar chart to certain midpoints. I would note, just as a point of reference, which is on that chart as well, in 2023, when we initially issued guidance for '23, we did that with an adjusted EBITDA range of $150 million to $170 million, and we closed '23 at $171 million of EBITDA.
So again, especially as we look at outer years, we're providing for some variability in the range and some of the factors that I mentioned could drive results to one of the range or the other.
