Northern Star rebuffs Gold Fields takeover play
Northern Star Resources (ASX: NST) rejected a $38.7 billion takeover offer from Gold Fields, citing undervaluation. The proposal, made on September 14, offered 0.3125 Gold Fields shares and $7.25 cash per Northern Star share, initially valuing it at $27 per share. The board deemed the offer inadequate and opportunistic, with 73% of the consideration in Gold Fields shares. Northern Star is undergoing leadership changes and operational updates, which it believes will demonstrate its value.
