Caterpillar Inc. (NYSE:CAT) will look for acquisitions. Chairman and Chief Executive Officer D. Umpleby said, "we're very willing and able to invest R&D to help meet the sustainability goals, both for us and our customers that we've talked about. We -- maybe we answer this question is we intend to invest the R&D we need to invest, but we also intend to meet our Investor Day targets for operating margins and free cash flow.

So that's really the way we look at it. And as we develop those products, as always, it will be a combination of things. If it makes sense for us to have an acquisition that helps us there, we can do that.

I believe that the vast majority of it will come from our own R&D and investing in the products. But we have made a few acquisitions here over the last couple of years, in small acquisitions that have helped us from a technology perspective, and we're continually on the hunt for other potential acquisition opportunities that can help us in our journey".
