I read that since CPT-symmetry is not broken, and CP-symmetry is, T-symmetry must also be broken, is that correct?

If that is correct, does that mean that energy isn't conserved?

T is not symmetric under reversal but still symmetric homogeneous under translations. So by Noether's theorem, energy is conserved.
