Calcbench does not adjust for stock splits.
Because filers report trailing periods (2 generally) they will report revised per-share numbers after splits. If you are not getting "as-originally reported" data from Calcbench you will get the revised numbers.
For instance on July 20, 2021 GE reverse-split their shares 1-8. When they report the full year numbers in January 2022 their dividend and EPS numbers for 2021 will reflect the reverse-split. They will also report revised EPS and dividend numbers for 2019 and 2020. In the Calcbench stream the newly reported EPS numbers will appear as revisions of the 2019 and 2020 numbers.
