Yes, it seems that this is Ace's specialty. I might have given Ace some bonus dice, given how perfectly tailored this is to his area of expertise, but he has already hit his Mental limit.
The junior Nately sounds very young, maybe 19-20. How familiar he is with corporate protocols is an open question. (The age difference between the elder Natelys and the younger Nately is also significant. It's possible Nately III is a grandson rather than a son, or perhaps the Natelys were wealthy enough to afford the medical attention to conceive at age 50+, but not so wealthy as to afford leonization. Or maybe there's a weird nano-molecular disease going around that has people nervous about gene treatments.) If Nately III is "halfway around the globe", Ace would guess that he is attending university abroad, or perhaps on a Grand Tour, but is probably not involved in day-to-day life at the corporation yet.
The old man is still on the Board of Directors, having stepped down as CEO 10+ years ago. While he probably provides strategic vision and oversight, his involvement is decidedly more removed. While having your Chairman kidnapped is certainly an embarrassment, it's not a threat to the day-to-day operations of a firm.
The young Nately's response will probably be to contact corporate security first. Depending on their local resources, corporate security may or may not contact local authorities for assistance depending on the perceived threat to the corporate asset. Nately Enterprises certainly wouldn't want this to become public if they could help it, but PCC's SecForce is a formidable and valuable resource if the corp doesn't have local operatives of their own. SecForce would not respond kindly to kidnappers in Aspen. In another situation they might de-prioritize it as an extraction attempt - the usual corporate shenanigans - but nobody's dumb enough to think that the Chairman of the Board can be extracted from the firm that bears his family name.
But to answer the original question, corporate negotiators would reach out to make contact and try to gather information, including a list of demands. Corporate security would model the potential cost of an operation to retrieve the asset versus the stated demands of the kidnappers and the likelihood that the kidnappers will keep their end of the bargain. Whether or not the firm takes it personally (since corporations are people, don't you know) that you've kidnapped the patriarch, and whether or not that changes the equation or their response, is an unknown. Maybe they are cold-blooded bean counters willing to let the mostly-retired Nately III drift in the wind, or maybe they'll unleash hell, looking for vengeance against anyone who would tarnish the family image. In either instance, they would try to make a deal, but who knows whether they would play it straight or if they'd really just be buying time to get their assets in place to murderize the team.
