Arizona-Based Freeport McMoran's Annual Audited Pretax Losses Were Reduced By $9.8 Bil During the Eight Years of the Obama/Biden Administration. The Other Arizona Companies Also Showed Substantial Earnings Improvement on the Audited Annual Pretax Earnings Growth Front During Obama/Biden's Eight Years in Office 2009-2016 (Up a Simple Average Annual Growth of an Off-the-Charts 237% Per Year), Much Better Than They Did During Trump/Pence's First Three Years in Office 2017-2019 (Up a Simple Average Annual Growth of 4% Per Year)

From a review of SEC filings and Google Finance, there were 20 Arizona Companies with stock market caps in late July 2020 of above $1 bil and which reported Pretax Income (Loss) From Continuing Operations in their annual financial statement earnings information filed with the SEC for each of the most recent twelve years (Fiscal Years from 2008-2019).  I only included Companies that were headquartered in Arizona for at least 6 of these 12 years.

The table below shows the Pretax Income (Loss) From Continuing Operations for each of these 21 Arizona Companies for fiscal year end 2019, the last year of the Donald Trump/Mike Pence's first three full years in office so far,  for fiscal year end 2016, the year before the start of the Donald Trump/Mike Pence Administration as well as also the last year of the Barack Obama/Joe Biden Administration, and for fiscal year end 2008, the year before the start of the Barack Obama/Joe Biden Administration.
