Who benefits from the reconstruction of Ukraine?

Yes, it's a macabre topic - but the reconstruction of Ukraine will bring investment and economic opportunities that are already being talked about. The question is: which companies could benefit the most? Will construction companies like $DG (-0.15%) and $HOT (+0.35%) , machine manufacturers such as $CAT (+0.86%) or energy companies like $ENR (+2.08%) get the biggest contracts? Who do you think could play a central role in this reconstruction project?
