I’ve heard that it also predicts at very low precision, some values that are practically measurable, and, unsurprisingly for how little precision these predictions have, these predictions are correct (I.e. the experimental results are within the predicted range).
(Or, maybe “a prediction” rather than “predictions”? I only heard about one, and I forget what it was.)
I am aware of no case where it clearly made an advance prediction of any behavior that later turned out to be true.
I'm aware of quite a few where they managed to "predict" something we already knew.
That said, they've made so many "predictions" that I'm sure that some likely worked out by sheer coincidence.
I think the prediction you may be referring to is supersymmetry, which was apparently empirically disproved by the LHC, or at least the supersymmetric extension to the standard model was disproved.
