MATERIAL INFORMATION

The Company informs that S&P Global Ratings has downgraded Avianca Holdings S.A. from “B” to “CCC+”, while reducing its rating outlook from Stable to Negative. The full report issued by S&P Global Ratings is available on the Company’s website (www.aviancaholdings.com) under “Investor Relations––Avianca Holdings S.A. Issuances—Bond Documents.”

The report issued by S&P states that Avianca’s plans to refinance its $550 million senior unsecured notes has taken longer than expected, given several reasons. S&P believes Avianca faces a higher refinancing risk due to the approaching maturity of its $550 million senior unsecured notes on May 10, 2020, and potential implications in the cost of financing. S&P states that the Company is addressing this refinancing risk to improve its debt maturity profile and liquidity prospects and that it could raise its ratings on Avianca Holdings if the Company successfully refinances its 2020 Notes.

As Avianca Holdings reported on May 6, 2019, the board of directors authorized the management of the Company on May 2, 2019, to proceed with a liability management transaction in relation to its outstanding 8.375% notes due 2020.
