Norsk Hydro: Primary insiders purchase shares under Long-Term Incentive program and shares to employees

Members of Hydro's Corporate Management Board and primary insiders have received shares in Hydro via the Long-Term Incentive plan and the employee share purchase program. Long-Term Incentive plan Norsk Hydro ASA has a share-based Long-Term Incentive (LTI) program in the form of a maximum remuneration of 30 percent of the annual base salary, dependent on two equally weighted performance metrics for the President and CEO, and the other members of the Corporate Management Board. The two performance measures are 1.) Hydro's three year average adjusted RoaCE relative to Hydro's adjusted RoaCE target, with adjusted RoaCE based on market value of equity, and 2.) Hydro's three year Total Shareholder Return (TSR) relative to a group of peers. The LTI payment is conditional on Hydro having a positive adjusted EBIT in the previous year. The participants will be required to invest the net amount after tax in Hydro shares and they must hold the shares for at least three years. The list below sets out the primary insiders that on April 18, 2024, have been allocated Hydro shares under the LTI plan at NOK 56.48 per share.
