The big unknown is why SAMR impacted H2 FY18 China sales. After all, the delay of application of this new law was extended to Mar19. Expect a major stock write off of China label in H1 FY19 if they failed to sell it.
The GS CFA expected $125m in sales for H1 FY19, that is roughly a 15% decrease from $150m sales in H2 FY19. They have factored no China label sales in H1 FY19. If GS is right, BAL management have mislead us with a 15% sales decline (which should have been max of $27m to $153m). Variances of this nature make up a good $1 in SP, a material omission in my opinion.
