Morphology

thereat = there (semi-transparent) = at + there

Built from the clear locative elements 'there' + 'at', but the sense 'as a result of that' is an idiomatic/discourse extension rather than a purely locational meaning. [Postprocessing: moved 'at' from base_words to prefix]

Etymology

Thereat comes from the simple parts there and at, which together pointed to 'at that thing'. Over time people used it to mean 'because of that' or 'as a result', so thereat can mean 'as a result of that'.
