R.02 / MAJOR DECISIONS

The decision record

Six documented decisions, each assessed as it looked at the time — avoiding hindsight — with alternatives and criticism where they were publicly discussed.

D1

Criticism

Long-term significance

D2

From energy to retail

Context
Ceconomy had been led by an interim CEO for about 18 months and was buying out the Kellerhals family's minority stake in MediaMarktSaturn.
Decision
Leave E.ON to become CEO of both CECONOMY AG and Media-Saturn-Holding from August 2021.
Why it mattered
His first CEO role, and the end of split leadership at the retailer.

D3

Committing to public targets

Context
After a 2022 profit warning and a loss-making year.
Decision
Publish quantified 2025/26 targets at a Capital Markets Day: adjusted EBIT above €500 m, 30% online share.
Alternatives
Companies in difficult phases often avoid long-range public targets; Ceconomy chose to set them.
Outcome
The supervisory board extended his contract early in July 2023. He left before the target year.

D4

Accepting a cabinet post

Context
Contract at Ceconomy running until 2028; no previous political office.
Decision
Accept Friedrich Merz's offer and leave Ceconomy by mutual agreement on 5 May 2025.
Why it mattered
A rare move from a listed-company CEO role directly into the federal cabinet.
Criticism
LobbyControl criticised his association roles. JD.com's takeover offer for Ceconomy came three months after he left; no evidence links him to it.
Immediate outcome
CFO Kai-Ulrich Deissner became interim CEO.

D6

Two contested positions: Palantir and the AI Act

Palantir
In an August 2025 interview he expressed openness to using technologies such as Palantir's to protect the state, while calling for European alternatives. Justice Minister Hubig was reported to be sceptical.
AI Act
At the November 2025 summit, Germany and France called for postponing the AI Act's high-risk provisions by 12 months.
Criticism
netzpolitik.org argued that the Palantir stance contradicted his sovereignty rhetoric; the Greens urged him to defend EU AI protections.
Status
The final EU outcome on AI Act timing is not covered here, as it could not be verified for this archive.
