Negative GM is not good, but one has to recognize that it is way more difficult to achieve good GM on wafer sales than on module sales. Operating margin and especially operating cash flow can still be ok for wafer sales compared to module sales even if modules GM looks better than wafer GM. They'll hopefully breakout the module GM, so we can compare that to peers. My guess is it will be only be slightly positive.
At this point the expectation should be that poly and wafer heavy companies should have the most GM difficulties in 2H. Even GCL will look weak.
