A tranche is one slice of a larger financing or investment that is released, sold, or paid out in separate parts rather than all at once. Investors care because each slice can carry different risk, return and timing—like buying pieces of a cake where some slices are richer or come later—so the specific tranche you hold affects when you get paid and how much you might gain or lose.
