Science Group, a UK-based science and technology consultancy firm, repeated its demand for board changes at Ricardo, a British consulting firm, on Monday.

This comes after the firm’s initial call for replacing the chair and two other directors was turned down last week.

At present, Science Group holds more than a 15% stake in Ricardo. The firm expressed its disappointment over Ricardo’s board’s lack of constructive engagement with them.

Science Group blames the current chair for the missed financial targets and weak balance sheet of Ricardo. The firm has strongly suggested that these financial issues could be addressed by altering the board’s composition.
