Probably less so from the trucking company perspective but more from the mathematic modellers; I actually work in this kind of field, and there can be a real issue with lack of diversity of thought which stiffles creativity and innovation. We take grads on every year, and they're practically clones - mostly young men, mostly white (although not exclusively), who have generally come from nice middle class backgrounds and done the exact same courses at a handful of universities. The course gives them good technical skills, but they have all been trained the exact same way and so the way they approach things tends to be very similar.
Bringing in people from different backgrounds really shakes that up sometimes and creates a diversity of thought. That leads to better, more robust products in most cases because flaws that would otherwise be missed are spotted, questions which weren't even thought of are suddenly asked.
So from the trucking company perspective I think there is a reasonable chance that the more diverse company might have a stronger product - but how you define diverse is the important thing as you could theoretically tick a lot of the big boxes and still end up with a culture which doesn't benefit from that diversity because they've still looked for people who fit a particular mold.
