Michael Riordan founded the company in 1987 in Foster City, California. Antivirals defined it: Tamiflu, then the HIV franchise built on tenofovir including Truvada and Biktarvy, and Sovaldi and Harvoni, hepatitis C cures whose high prices and rapid uptake became a national pricing debate because curing patients shrinks the market. Oncology arrived through the $11.9 billion Kite Pharma acquisition in 2017, bringing CAR-T cell therapy, and Trodelvy came with Immunomedics. HIV prevention remains the largest business.

Gilead Sciences equity questions

How much does it cost to hedge GILD stock?
The cost of a protective put depends on how far below the current price you set the floor, how long the protection lasts, and GILD's option-implied volatility. A zero-cost collar lowers that cost by selling away some upside. The calculator above prices both structures off the current GILD option chain and shows the annual cost, maximum loss, and tax treatment.
Does Gilead Sciences grant ISOs, NSOs, or RSUs?
Equity compensation at Gilead Sciences typically takes the form of restricted stock units (RSUs). Restricted stock units are taxed as ordinary income when they vest.
Do Gilead Sciences RSUs use double-trigger vesting?
No. Gilead Sciences 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.
