(Adds latest offer in bidding war for Netshoes)
SAO PAULO, June 13 (Reuters) - Grupo SBF SA, operator of Brazil's Centauro stores, again boosted its offer for Netshoes Cayman Ltd, this time to $4.10 per share, the latest move in a bidding war over the online sports retailer with Magazine Luiza SA.
According to a securities filing on Thursday night, the new offer raises the value of Grupo SBF's bid to about $127.3 million, a 10.8% rise over the previous $3.70 per share bid.
The bidding war underpins the importance to traditional retailers of internet merchants - even ones like Netshoes, which has suffered widening losses in recent years - to attract online shoppers who use their smartphones and tablets.
Shares in Netshoes ended up 10.5% on Thursday at $3.80, but still a fraction of their $18 IPO price in April 2017.
Earlier on Thursday, retailer Magazine Luiza matched Centauro's previous offer of $3.70, which represents an 85% increase from its initial bid of $2 per share disclosed at the end of April.
In its latest offer, SBF maintained a previously proposed loan of 120 million reais ($31 million) to boost Netshoes' immediate working capital needs, with a commitment to release 70 million reais two days after the signature of a merger agreement.
Netshoes' shareholders are scheduled to deliberate on the transaction on Friday. (Reporting by Ana Mano and Gabriela Mello; Editing by Chizu Nomiyama and Leslie Adler)
