Well...right... but not because of their relative lack of concern about the ramifications. Rather, its because minor, national corporations are not granted extraterritorial status. In fact, corporations up to and including A-rating multinationals lack extraterritorial status. Only AA and AAA-rating megas are afforded that consideration.

Note that the official description of AA megas indicates that they dont have a lot of trouble going "toe-to-toe" with the Big Ten - the only functional differences are that they lack a seat on the corporate court.

As a side note, I would be *very* afraid of a corp that managed to achieve AA status without anywhere near the level of diversification as is usually required to get that far. A corp like.... Lone Star.

Quite true - the word "national" should have been "extra-territorial" instead !

My take on Lone Star (not) being automatically invited into extra-territorial sites when chasing a suspect is derived from how governments act today. IMO megacorps would treat their own ground as jealously as countries do, perhaps even more so because of limited space and the higher need for security in the 2060s. After all, LS belongs to another megacorp, which is a good reason in itself not to always let their people in. Then there's all those pesky issues of liability, lawsuits and especially precedents. Corp lawyers hate those, and CEOs listen.

Cost effectiveness is a good argument for low-threat offenders who can be nabbed by Lone Star quickly, without much penetration into the facility. Major threats would at the very least warrant a joint LS - corp action against the intruders, or maybe even corp assets alone. In either case, no corp is going to leave itself open to improvisation by not signing a fat contract with the "outside" national jurisdiction and its agencies (see mention about corp lawyers' pet peeves above). Such an agreement would detail terms of entry, compensation, lines of communication, liaison officers, classification of threats, etc.. Some of these issues are already in place between countries today (like the US and Canada, or EU members) and I see no reason why the SR universe would allow for a simpler, more open system - quite the contrary, since this is SR and the corps are all about control and profit.

Also, I wouldn't allow runners much more than a few seconds of grace if they move into another jurisdiction while being pursued. It makes sense that corp security managers have access to some sort of emergency "liaison channel" into which Lone Star can temporarily switch its tactical communications when chasing suspects near extra-territorial facilities. Provided the corp enclave isn't an open house and has limited access, the corp people could easily know in advance that runners are coming in, and supply the proverbial anvil for the Lone Star hammer.

That's why heat-seeking ordnance was developed in the first place - the speediest extradition measure available, without any of the associated confinement costs.
