Iberdrola SA said Wednesday that it increased its offer in a takeover bid for Infigen Energy Ltd and Infigen Energy RE Ltd.

The Spanish utility company said it would offer 92 Australian cents ($0.66) per stapled security to acquire Infigen, up from AUD0.89 previously.

The increase is conditional on Iberdrola Renewables Australia receiving acceptances of its offer for at least a further 13% of Infigen's stapled securities by July 30.
