Why Pfizer and BioNTech Got Thrashed on Thursday

In what hardly qualifies as a surprising development, shares of both Pfizer (NYSE: PFE) and BioNTech (NASDAQ: BNTX) fell in price on Thursday. This was on the back of a Supreme Court decision that struck down a key government vaccination mandate.

The two companies are perhaps best known by the general public these days for the Comirnaty coronavirus vaccine, so they were directly in the line of fire when the decision was handed down. After the smoke cleared, Pfizer's stock price fell by nearly 2%, while the far smaller and less diversified BioNTech suffered an 8% hit.
