Employee Stock Purchase Plan

With the Amgen Inc. Employee Stock Purchase Plan (ESPP), eligible staff members can purchase Amgen common stock at a discounted price.

To be eligible, you must meet two requirements: you must be employed by Amgen or a wholly owned subsidiary incorporated in the U.S or Bermuda (except for staff members of Amgen Manufacturing, Limited) on the Offering date and customarily work at least 20 hours per week and at least five months per calendar year; and you must have been employed by Amgen Inc. or a wholly owned subsidiary for at least twelve consecutive months as of the day before the Offering begins. If you participate in the ESPP, Amgen will use your accumulated, non-interest-bearing contributions to purchase, on your behalf, shares of Amgen common stock at a 5% discount off the closing price on the purchase date.

The plan has two offering periods each year. During the enrollment period for each offering period, you may elect to purchase shares of stock with up to 15% of your eligible pay. The Internal Revenue Service limits the amount of stock that can be purchased in a calendar year to $25,000, as valued on the date the offer to purchase the stock was granted.
