Most likely for the same reason why with your ruler tape looks damaged around the 2.75" mark:
Application of excessive exterior force.

That damage would take an excessive amount of force. I can’t comprehend how that’s user error...on the other hand, most of my tape measures ultimately suffer a similar fate.

I have no clue how it could happen without that.

Most likely it's a storage problem, like that it was squeezed into some area that dosn't have the needed dimensions to accept the rail in the original geometry or put somewhere where it wasn't fully supported and something was put against/onto it.

Aluminium isn't that hard to deform and the flat part (without the T-slots) isn't that thick and the center of the bend seems to be located right to the center of the rail (in the flat part).

Answers to questions like
- is that bend even over the whole length or only on the end?
- how is this normally stored and, in case it's not a shop-only rail, moved?
- what 'could have delivered excessive force' encounters did this rail have?
might help for further speculation on how this could have happened to it.
