Estate note. Heirs receive a stepped-up basis at death (§1014), eliminating built-in gain on inherited shares. Older holders who plan to bequeath rather than sell may rationally never de-concentrate.

Agilent Technologies spun off from Hewlett-Packard in 1999, going public that November in what was then the largest IPO in Silicon Valley history. The company makes lab instruments and consumables used to analyze chemical and biological samples: chromatography and mass spectrometry systems, diagnostics reagents, and genomics tools, sold to pharmaceutical, academic, and industrial labs. In 2014 it spun off its electronic test and measurement division as Keysight Technologies, narrowing its focus to life sciences, diagnostics, and applied chemical markets. Agilent reported $6.95 billion in revenue and about 18,100 employees for fiscal year 2025, which ended October 31.

Equity comp at Agilent

  • RSUs use single-trigger vesting: shares become yours as each portion vests on schedule, and the value is taxed as ordinary income at that point. No IPO or acquisition is required.

If a meaningful share of your net worth sits in A, concentration risk is the question. This calculator quantifies drawdown impact at 30 / 50 / 70%, and the trade-off between selling down (tax cost now) versus hedging (option premium drag), auto-filled with A's option-implied volatility.

Example: 5,000 A shares at $172.31 is a $861,550 position. A 30% drawdown costs $258,465; a 50% drawdown costs $430,775; a 70% drawdown costs $603,085. The calculator quantifies the trade-off between selling down (immediate capital-gains tax) and hedging (option premium drag) using A's option-implied volatility and your cost basis.

Agilent equity questions

How much A 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 A position and weighs selling down (which triggers capital-gains tax now) against hedging (which costs option premium).
Does Agilent grant ISOs, NSOs, or RSUs?
Equity compensation at Agilent typically takes the form of restricted stock units (RSUs). Restricted stock units are taxed as ordinary income when they vest.
Do Agilent RSUs use double-trigger vesting?
No. Agilent 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.
