"under-delivering"

Delivered millions of EVs that everyone said would never work, dragging the entire car industry out of its stupor.

Delivered a vast electric charging network and made it available to the competition.

Delivered the best satellite internet.

Delivered rockets that NASA uses.

Delivered the most payload to space, more than even China.

Gee, imagine under-delivering that badly.
