At $1.10, with a 9.0% required return and a 18× earnings multiple in 5 years, earnings per share must grow about -7.7% a year, to $0.09. On that path the next quarter needs diluted EPS near $-0.12, against $-0.13 in the quarter ended Sep 30, 2025.
Compare buying at the last close now with waiting for results: if the report moves the growth the price requires, the entry price you would accept changes with it.
