The company sells the consumable hardware inside biologic drug manufacturing: filtration devices, chromatography resins, and single-use flow path components that let manufacturers avoid cleaning validation between batches. Growth followed the industry shift from stainless steel to disposable bioprocessing, and a long acquisition program assembled the product line. Revenue is exposed to customer inventory cycles, which produced a sharp correction after pandemic-era overbuying. Headquarters are in Waltham, Massachusetts, and most sales flow through large biopharmaceutical manufacturers and their contract partners.

Repligen equity questions

How much does it cost to hedge RGEN 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 RGEN'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 RGEN option chain and shows the annual cost, maximum loss, and tax treatment.
Does Repligen grant ISOs, NSOs, or RSUs?
Equity compensation at Repligen typically takes the form of restricted stock units (RSUs). Restricted stock units are taxed as ordinary income when they vest.
Do Repligen RSUs use double-trigger vesting?
No. Repligen 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.
