The problem is Beyond will not brake even during it's theatrical run. Not even close. Most likely due to it's overblown budget, but also because the don't earn much money domestic.
It has a budget of 185 mio, and has earned 285 mio. worldwide yet. Because of the shares for cinema chains, distributers, advertisement et al. a Hollywood movie needs to make about 2x it's budget to break even. Star Trek Insurrection did 112 mio. on a 58 mio. budget. That's a multiplier of ~1,95x, and it finally made a profit with DVDs, merchandise, and granted a sequel.
Beyond would need a box office of 370 mio. to break even, with a 2x multiplier - which is actually generous when so much of your budget comes from overseas, where the multiplier usually needs to be better - see Terminator Genisys, which made 444 mio. world wide (a number Beyond can only dream of) on a budget of 155 mio. (a budget Beyond can only dream of), but was STILL considered a flop. Beyond will most likely end up between 300 and 350 mio. In pure numbers Beyond did a lot worse than Terminator:Genisys. But it made a bigger share of it's profit domestic, which is good (as in -not a flop-, not -a success-)
Beyond is not a bomb like Nemesis was. But it's not a mild success like Star Trek: Insurrection was either. It's somewhere inbetween, but closer to the Insurrection side of things. So yay for a sequel...?
