From their 'analysis':
"Record profits on petroleum and mining activities (reinforced by a spike in global oil and gas prices following the invasion of Ukraine) led this surge, but the overall corporate sector experienced the most rapid growth in profits of any comparable period in 35 years."
So because of global shortages, commodity prices reached record highs, and companies most of which are price takers benefited from that, is now suddenly corporate greed?
BHP doesn't set the price for Iron Ore, the market does. BP doesn't set the price for Oil or Natural Gas, the market does. When you cut off Russia who are a key supplier of those goods, that creates shortages and causes prices to spike. This means companies which extract those goods will make more money as long as costs remain the same.
Most companies aren't making record breaking profits, their profits are rebounding to pre-COVID levels. Of course they look good compared to COVID times, when demand was suppressed.
