tracking data and the fighter jet pilots’ observations, it is “likely that the pilot of the accident airplane became incapacitated during the climb to cruise altitude.”...
Well, who wouldn’t?
Do they say why the jet lost pressure?
Shades of Payne Stewart.

The NTSB report is preliminary, but answers most of the early speculation. I can’t source a link to the preliminary report itself and won’t be expending any more time on it.
Final report isn’t expected for another year.
From the source:
“Five things on the plane were overdue for maintenance inspections at the time of the crash, including a co-pilot oxygen mask, the NTSB found. An additional 26 problems were noted on the aircraft a month earlier, “including several related to the pressurization and environmental control system,” but the owner chose not to address them, the board reported. Two days before the crash, maintenance workers also saw the pilot’s oxygen mask was missing and oxygen levels were so low that passenger masks would not have worked.”
