How is true news produced?

There is a popular association that play to retired citizens. As I read a May 2017 Bulletin in a waiting room it become notable they were highlighting the cost of prescription drugs, and why the cost is high. I can applaud the effort but noted how they made a point of the drug company profits. The report listed the performance of Drug company profits in comparison to S & P corporations. The listing  contained four major drug companies with their profits listed by percentages. Further down the list the S&P corporation percentages were listed.
To test what I was being told I calculated the top percentage drug company's percent ptofit as compared the the eighth corporation's percent profit listing.
The  AMGEN  drug company was listed as receiving a 42.6% profit in the year 2016.
VERIZON was listed as earning a 21.5% profit during 2016. 

I GOOGLED two selected corporations at random.

A comparison is that the AMGEN dollar amount was 42 %0f 74 billion or 24 Billion profit.  The Verizon percent profit as listed was 21.3% was against 126 billion, or 26.8 billion.

This comparison is not meant to protect, or point fingers at the profitability of any corporation as compared to another. 

The comparison makes one wonder if the AARP in their May 2017 report was intended to provide facts or throw mud at Drug companies. If you are a member maybe you should compare the sixteen companies on the list.

How factual is the news?
