As of May 12, ENKRAFT owns 5.03% of the company, up from 3.13% previously, a stake currently worth around 50 million euros ($52 million).

PNE will hold its AGM on Wednesday, at which Morgan Stanley, which owns around 40% of PNE since 2020 following a failed takeover attempt, is seeking a majority of seats on the group's supervisory board.

To prevent that from happening, ENKRAFT, which at the time had slammed Morgan Stanley's 4-euro-per-share bid as too low, has proposed two of its own candidates for election to PNE's board, including ENKRAFT managing director Benedikt Kormaier.

PNE shares are currently trading at 12.66 euros per share.
