Queensland coal baron Brian Flannery has divested his share in a local fast-charger developer. 

Reports say Flannery, whose foray with Brisbane-based charger company Tritium began in 2017, has been critical of the company's strategy and operational decisions, particularly questioning the prudence of maintaining production facilities in both Brisbane and the United States. 

From an 8 per cent stake worth $US96 million at the company's 2021 Nasdaq debut, his stake's value allegedly plummeted to around $US1 million.

The sale comes at a critical juncture for Tritium, with shares hitting an all-time low on the Nasdaq and its negotiations with Lite-On Technology of Taiwan making no headway.

Tritium, which launched on the stock market with a valuation of $2 billion, faces the risk of delisting from the Nasdaq after its share price languished below $1 for an extended period. 

This development has raised the stakes for Tritium, struggling to secure funding for its expansion plans, including the establishment of a second manufacturing site in the US.
