22 May 2018business combination● NeutralMajor

The Board unanimously rejected Harbour's 'best and final' US$5.21 offer as not reflecting full value, and ended all talks. It cited the higher oil price, currency risk, a leveraged structure and unequal treatment of ENN/Hony. Ends the takeover thread.

Harbour lifted its binding conditional offer to US$5.21 (A$6.95) per share, after US$5.12 on 19 May. It is conditional on extra oil hedging, and would rise to A$7.00 if Santos hedges 30% of 2020 oil-linked production. Shareholders take no action.

17 May 2018business combination● NeutralMajor

After five weeks of due diligence, Harbour made a binding, conditional scheme proposal at the same US$4.98 per share. It is now all US-dollar cash, with ENN and Hony alone offered a rollover. Independent directors will consider it; shareholders take no action.

16 May 2018business combination● Neutral

ENN told Santos that media reports were mistranslated: it intends to engage with Harbour, but no agreement exists. The 2017 agreement still requires ENN and Hony to vote and sell in line with a majority Board recommendation. Shareholders take no action.
