SK should have separated Q1 from Q2 revenue in its PR. The PR stated Q2 of $18mil which is, in fact,  a consolidation of the Q1 (less than one month long)  of $5mil with the Q2 $13mil.

It's understandable SK is not looking at Q1 as a full quarter, but the PR gives the appearance there was a  decrease (18mil to 13mil, Quarter to Quarter) which is not the case.
