Bogotá, May 16 ^th , 2018. GRUPO AVAL ACCIONES Y VALORES S.A. (“Grupo Aval”) reports a consolidated attributable net income result of Ps 597.7 billion (Ps 26.8 pesos per share) for 1Q18 versus a Ps 466.7 billion (Ps 20.9 pesos per share) figure reported for 4Q17. ROAE for the quarter was 15.3% and ROAA was 1.6%.

•

Slow loan growth continued during 1Q2018 across all loan categories, but mainly in corporate loans. It is expected that growth recovery will gain momentum in 2H2018 due to positive macro trends and less political and fiscal uncertainty.

•

The 1Q2018 Tangible Equity Ratio reflects the one-time adjustment due to the adoption of IFRS 9 and a seasonal annual impact due to shareholders´ dividends.

•

30 days PDL and 90 day NPL were 4.25% and 2.86% for the quarter. On a positive note, for the third consecutive quarter the amount of new loans becoming 90 days past due decreased suggesting the end of the cycle might be near.

•

Cost of risk for the quarter was 2.3%, including 24 bps of impact due to specific large corporate exposures (primarily Electricaribe).

•

NIM during 1Q2018 showed resilience with a consolidated decline of only 10 bps versus 4Q2017.

•

Fee income ratio continued to hold at 26% for the quarter with pension and banking fees growing at a similar pace than consolidated assets.

•

Improvement in the efficiency ratio shows the results of the continuous effort on cost control initiatives which will remain in effect in a scenario of low growth.

•

Net income for the quarter was $598 billion or Ps 26.8 per share and ROAE for the quarter was 15.3%.

Gross loans excludes interbank and overnight funds. Tangible Capital Ratio is calculated as Total Equity minus Goodwill and other Intangibles divided by Total Assets minus Goodwill and other Intangibles. Net Interest Margin includes net interest income plus net trading income from investment securities held for trading through profit or loss divided by total average interest-earning assets. Fee income ratio is calculated fee net income divided by net interest income plus net trading income, other income and fees and other services income, net (excluding others). Efficiency Ratio is calculated as personnel plus administrative and other expenses excluding wealth tax divided by net interest income plus net trading income, other income and fees and other services income, net (excluding others). ROAA is calculated as annualized Net Income divided by average of total assets. ROAE is calculated as Net Income attributable to Aval's shareholders divided by average attributable shareholders' equity.

The increase on impairment loss on loans and accounts receivable in 1Q18 versus 1Q17 was mainly driven by an increase on impairment losses on our commercial loan book.

The decrease on impairment loss on other assets in 1Q18 is explained by the reversal of USD 17.3 million (Ps 49.4 billion) impairment, registered in 2Q16, due to the sale of our investments in OI and Telemar in 1Q18. This decrease was offset by a USD 17.7 million (Ps 50.5 billion) loss on sale on investments.
