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.

21 May 2018business combination▲ GoodMajor

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.

15 May 2018business combination● Neutral

Santos says it has no notice of any agreement between Harbour and ENN, its largest shareholder, despite media speculation about an ENN trading suspension. There is no certainty the Harbour proposal becomes an offer; shareholders should take no action.

Melbana said the regulator granted a six-month extension, to 21 September 2018, of the WA-488-P permit year. This gives time to secure the environmental permit for the Beehive 3D seismic, still targeted for mid-2018. It continues the Total/Santos funded option to take 80%.
