RE:Here are Tikrays historical EPS results- Quinlash provided a link to explain EPS, but it only applies to companies with positive earnings.
I don't believe the positive EPS numbers in the table you provided are correct. The only reliable source for numbers are the quarterly filings, and even they are subject to errors. At least I assume they are unintentional.
For the quarter ending on Nov 30th, 2021, (2022/Q2) Tilray had a comprehensive loss attributable to shareholders of $41,853,000 with 460 million shares issued.
The Q2 EPS was -42/460 = - .09, but the report inexplicably shows an EPS of 0.00 .
The six-month EPS is reported as - .09, but the actual EPS from the numbers in the report is -185/455 or -.40.
The report is here:
