They should be fine, as they have been in the freezer since the purchase.
When you shoot the first roll you can also go the "very safe route" and make tow exposures per subject: One with exposure at EI 400/27°, and another one with EI 320/26°.
because in the worst case the films may have lost 1/3 stop in speed, but certainly not more because of the refridegeration.
