Ann: Quarterly Activities Report, page-36

This is yet your wierdest question/assesment "Why didnt prices drop only 13% 20-7=13?"

For your courtesy i attached the relevant page for roughly calculating EBITDA, but the easy answer is that when your revenue for each tons goes down~20% basically that 20% revenue loss almost entirelly get deducted from your profit margins which here the 20% revenue /t reduced margins by~4000 USD/t offseting the margin loss there were some ~900USD/t cost improvements during Q3. So in June quarter the EBITDA margin was 19943-14503=5440 after some accounting deduction the final june quarter EBITDA margin was=~5367USD/t.
In September quarter the margin decreased by -~4000USD but the cost profile improved by +~900USD (19943-4000=) ~15950-(14503-~900=)13597= 2353 after some accounting deduction you arrive to~2261US/t EBITDA margin for the quarter. I hope this helps.

About the cap raise:
I think you were wondering about the~100M US share placement in Q1 2022. I think the cashflow section can be your guide from Q1 i attached it,if its not the one and i missed another cap raise let me know.
