Came across an earnings forecast from exactly a year ago and the scale of ATM's downgrades & market reaction can best be summed up by these numbers :
Revenues EBITDA EPS
F21E 2,101m 650m 62
Updated 1,227m 151m 13
F22E 2,426m 756m 72
Updated 1,387m 282m 25
The downgraded numbers for F22 are sobering : Revenues downgraded by 43% and EPS by 78%!!!
