A319: 200km
B737: 400km

A319: 200km.
B737: 400km.
Which is correct? Period or no period in a bullet point list of numbers?
I would not use a period unless the bullet points were full sentences. Also most style guides recommend a space, or a "thin space" between the value and the unit, so "400 km" not "400km". A thin space is the official SI standard, if I am not mistaken.
As David Siegel mentioned above, the bullet points are not full sentences in this case, and you do not need to use period. Instead of this, you can put a semicolon at the end of each row (and use a period at the end of the last item) - you will keep the continuity of the list then. Some writers consider that it is not the best business writing choice, so you may just skip periods.
