It's probably because MOS switched from a fiscal reporting cycle to a calendar cycle. The last earnings report was Q4 on the old reporting cycle which ended 5/31/13. The next earnings report in early November will be Q3 on the new reporting cycle. This makes it difficult because the company has reported for 5 of 12 months so far instead of 6, so it's hard to effectively dissect the numbers. We know the EPS for March-May 2013, but not for Janaury-February because they only gave us December-February as a whole. I don't recall seeing a 5 month EPS figure from the company anywhere. Someone please jump in here if you saw a 5 month total. I don't have time to go through the SEC filings right now.
MOS gave some sales and expense guidance for Q3 2013, but no EPS estimates that I know of. Prior to the Russian debacle, MOS estimated Q3 potash pricing to be between $330-360. When MOS reports Q3 (July-September 2013) in November, they'll also give us the 2013 first half numbers. This is important because right now we don't know how they did in June. June is the one month which will not be included in any 3 month report as far as I know. It'll only be included in the 2013 first half numbers which we'll see in November.
Correction: I went back and read the original press release about the change to a calendar year and it states MOS will only report Q3 2013 in November. In February 2014, they'll give us Q4 2013 and the 7 month period from June-December. This is weird to me, but I don't make the decisions. I wish they would give us the June numbers earlier, but that doesn't seem to be the case. Maybe they'll change their mind and report 2013 first half numbers in November.
