The Abu Dhabi National Oil Company (ADNOC) announced it will be divesting a 20% stake in its gas pipeline assets managed by ADNOC Gas Pipelines to the Abu Dhabi Pension Fund (ADPF) and ADQ, a regional holding company.

The two groups will invest a total of $2.1 billion into select ADNOC gas pipeline infrastructure assets.

Under the terms of the agreement, ADNOC will divest 20% in ADNOC Gas Pipelines, a wholly owned ADNOC entity that holds 100% of ADNOC’s interest in ADNOC Gas Pipelines assets, to ADPF and ADQ.

ADNOC Gas Pipelines is a subsidiary of ADNOC with lease rights to 38 gas pipelines covering a total of 982 kilometers (610 miles).

In July, a consortium of global investors comprising Global Infrastructure Partners, Brookfield Asset Management, Singapore’s sovereign wealth fund GIC, Ontario Teachers’ Pension Plan Board, NH Investment & Securities and Snam, invested $10.1 billion for a collective 49% stake in the same select ADNOC gas pipeline infrastructure assets.

ADNOC also sold a 40% stake in its oil pipeline assets last year to U.S. investment firms KKR and BlackRock for $4 billion.
