No, the opposite.
NCM has equity market cap $12B - a claim of this size and agreed settlement is trivial to them, except reputationally.
For SGH with equity market cap ~$250m this size of (a) cash boost (b) boost to H2 forecasts (c) boost generally in confidence because of (a) and (b) has to hit sp by >5%. That's definitely "material" in my view - can't see how it couldn't be.
