With more than a week to go in the second-quarter earnings season, the health care industry has already banked more profits than any other quarter in the past year.

The bottom line: Company after company has posted profits that have exceeded Wall Street estimates, and most firms have raised profit estimates for the rest of 2018.

By the numbers: As of Aug. 2, 85 publicly traded health care companies have amassed $47 billion of global profit on $545 billion of global revenue in the second quarter, according to company documents.

  • That profit is higher than the $45.6 billion that 118 health care companies posted in the first quarter of this year, and it's higher than anything recorded in the past year.
  • Pharmaceutical companies continue to rake in the highest profit margins.
  • The numbers do not include not-for-profit hospital systems, which have not filed second-quarter reports yet.
  • Fatter profits are due in part to growing sales of prescription drugs, medical devices, tests and procedures — that reflects both higher prices and more quantities sold.
  • But the larger earnings also stemmed from Republicans' massive cut in corporate taxes. The income tax expense for drug giant AbbVie, for example, was 93% lower in the second quarter this year.

Tech was the first industry to send its workers home when COVID-19 first hit the U.S., and it has been among the most cautious in bringing workers back. Even still, many companies are realizing that their reopening plans from as recently as a few weeks ago are now too optimistic.

Why it matters: Crafting reopening plans gave tech firms a chance to bolster their leadership and model the beginnings of a path back to normalcy for other office workers. Their decision to pause those plans is the latest sign that normalcy is likely to remain elusive in the U.S.

The coronavirus pandemic has changed the game for U.S. businesses, pushing forward years-long shifts in workplaces, technology and buying habits and forcing small businesses to fight just to survive.

Why it matters: These changes are providing an almost insurmountable advantage to big companies, which are positioned to come out of the recession stronger and with greater market share than ever.
