My estimate is a little different. I have revenue at $16.3M. Same core as you at $10.5M but IGourmet at $5.8M. Last year IGourmet did $4.6M on their own. I put 27% growth on top of that which is in between the 23% and 30% reports from the three 2018 Q news releases. It may be high but I also haven't accounted for 3 months from Mouth.com.
Cost, I'm at 72% but basically similar to you. As usual it's the SG&A I have the hardest time predicting. If IGourmet keeps at the previous pace or the actual delivery costs eat up margin then you may be right. Meanwhile I'm thinking maybe 23% of revenues which is still a jump from $3M SG&A quarters to a $3.7M SG&A quarter.
With all that I'm at a 2.6 cent quarter (not accounting for taxes which I don't have a clue).
Either way we have to wait April 1rst to find out. Hoping better shareholder governance moves comes before then.
