Rating agency Care, which revised upwards the rating assigned to Aban's bank facilities (from D to BB-), said in a note, "The revision in the ratings assigned to the bank facilities of Aban takes into account improvement in capital structure consequent to mobilisation of fresh equity, improvement in the financial performance and completion of refinancing of debt at the group level."

After today's surge, the gain in Aban's share price this year is in line with the market at around 27%.
The stock has a 12-month price target of Rs 750 according to consensus analysts' estimates provided by Bloomberg.
