OBRASCÓN HUARTE LAIN, S.A. ("OHL" or the "Company"), pursuant to article 226 of the consolidated text of the Securities Market Act approved by Royal Legislative Decree 4/2015, of 23 October, hereby notifies the Spanish National Securities Market Commission (Comisión Nacional del Mercado de Valores) ("CNMV") the following

INSIDE INFORMATION NOTICE

In connection with the communications dated 21 January 2021 and 5 February 2021 (the "Announcements"), the Company informs that, as of the Early Accession Deadline, Noteholders representing over 93% by value of the outstanding principal amount of the Senior Notes have acceded to the Lock-up Agreement. In addition, the Company informs that Noteholders representing over 75% by value of the outstanding principal amount of the Senior Notes (excluding those held by the Backstop Providers) have elected to be treated as Option 1 Noteholders. In this context, the Backstop Providers have duly exercised their right to take up the full allocation of Option 2 Scheme Entitlements.

Accordingly, the Company informs those Noteholders (other than the Backstop Providers) that have elected to be treated as an Option 2 Noteholder (which represent less than 2.5% by value of the outstanding principal amount of the Senior Notes) that they have 5 business days from the date of the Backstop Provider Election Notice (9 February 2021) in which to terminate the Lock-Up Agreement in respect of that Noteholder only. Any such Noteholders that do not exercise this right, will automatically be treated as an Option 1 Noteholder.

Capitalised terms used in this announcement have the same meaning ascribed to them in the Announcement.
