My thoughts are a CR with Gridcomm wouldn't be badly received because they already have sales and demonstrated profitability - rather than being a case of "please help us pay our high fixed annual admin costs while we try to generate enough sales - sometime in the next few years - to support our growing executive remuneration target".
CR in this case should just be a sign of upscaling, meaning that future sales will be realised faster.

The greatest present risks for us are imo 1. no deal and 2. dilution leaves us with little gain, which has always been the case (though risk no 1 is apparently/supposedly becoming less significant)

I would personally welcome a CR with a detailed prospectus, as it would show the wider market how potentially valuable Gridcomm is.
