The move signals Triton's strong commitment to the tender offer, Crayfish said.

Triton on Tuesday offered Caverion shareholders 8 euros for each share through the private liability company Crayfish.

Triton's takeover offer represents a premium of 14.3%, which exceeds a bid of 7 euros announced in November by North Holdings, a Bain Capital-led consortium that had valued Caverion at 955 million euros ($1 billion).

It seeks the support of Caverion's board for its takeover and hoped to complete the deal in the third or fourth quarter.

($1 = 0.9218 euros)
