Under researched

Does anyone know if any analysts cover this stock?
I've started to have a look through the financials etc but have more questions than answers.

While profit (before tax) growth has been attractive over the past 6 years:
2016 $11,485
2015 $7,218
2014 $2,529
2013 $788
2012 -$399
2011 -$234

Revenue has been flat. So all of the gains in operating cash-flow and profit and loss have been attributable to the lowering of costs and in particular Raw materials used. Raw Materials as a percentage of sales:

2016 62.88%
2015 65.81%
2014 71.73%
2013 75.17%
2012 76.73%
2011 73.67%

There isn't any explanation that I can see as to what is causing this or how long this margin expansion trend will continue for (what do we think is the sustainable gross profit %).

I did see in the 2014 address to shareholders that number of eggs sold have gone from about 410mill eggs sold in 2010 to about 325mill eggs sold in 2014 (going off graphs not numbers) so number of eggs are dropping but revenue is flat so I assume there is some legitimate margin expansion (we are just getting more money for our eggs).

Also the investment in the new free range facility will obviously impact the profit and loss however management haven't provided any guidance that I can see around the size / scale and margins on this new facility.

Any help or guidance would be appreciated.
