Charles Pfizer and Charles Erhart founded the company in Brooklyn in 1849, and it scaled penicillin production during the Second World War using deep-tank fermentation. Lipitor became the best-selling drug in history before losing exclusivity in 2011. The Comirnaty vaccine with BioNTech and the antiviral Paxlovid produced extraordinary 2021 and 2022 revenue that then fell sharply, and the company spent roughly $43 billion on Seagen in 2023 to build an oncology pipeline against a patent cliff later this decade. Headquarters are in New York City.

Pfizer equity questions

How much PFE stock is too much?
There is no single threshold, but the larger the share of your net worth in one stock, the more a single bad year can set back your plans. The calculator above quantifies the drawdown impact at 30, 50, and 70 percent for your PFE position and weighs selling down (which triggers capital-gains tax now) against hedging (which costs option premium).
Does Pfizer grant ISOs, NSOs, or RSUs?
Equity compensation at Pfizer typically takes the form of restricted stock units (RSUs). Restricted stock units are taxed as ordinary income when they vest.
Do Pfizer RSUs use double-trigger vesting?
No. Pfizer restricted stock units (RSUs) use single-trigger vesting: each tranche becomes yours as it vests on schedule, taxed as ordinary income at that point, with no liquidity event required.
