LONDON--Mobile device banking and payments technology group Monitise PLC (MONI.LN) Tuesday reiterated full-year revenue expectations and said it remains in discussions with interested parties after effectively putting itself up for sale last month.

The company, which helps customers such as Spanish bank Santander to facilitate mobile payments and banking, reported a pretax loss of 58.4 million pounds ($89.3 million) for the six months ended Dec. 31, up from a GBP23.3 million loss the previous year, on revenue down to GBP42.4 million from GBP46.5 million.

Full-year revenue is still expected to be between GBP90 million and GBP100 million, in line with previously reduced guidance, the company said.

"The announcement of our Strategic Review has led to many constructive discussions with market-leading players interested in our business and the role we play in the industry," said chairman Peter Ayliffe.

Monitise said last month that it would launch a strategic review to consider options including the company being bought. The announcement came after a tough year for the company, which included lowering its revenue growth expectations and payments card company Visa Inc (V) cutting its stake in the firm.

The company still lists Visa EU, a separate company from Visa Inc, on its website among its major shareholders.

Monitise also said Tuesday that it has signed a letter of intent with a unnamed major European financial institution to deploy Monitise digital banking capabilities in several countries.

It also reiterated its long-term guidance of having 200 million people using its technology by 2018, each providing revenue of GBP2.50 a year. The company said it had 33 million users at the end of 2014, but didn't give specific figures for revenue per user.

Shares at 1021 up 2 pence, or 9.3% at 24 pence, valuing the company at GBP501.9 million.
