energy light interferometers

Description

In an interferometer, it is said that a light beam can be "cancelled" by splitting it in half, delaying one half-beam by half a wavelength, and recombining this with the other fraction.

If this is true, where does the energy of the light beam end up? Assume that the light beam is monochromatic, and the interferometer is in a vacuum. (ZBL#154).
