History
Santos grew from an Australian gas producer into an LNG company through GLNG, PNG LNG, Quadrant and Oil Search, then brought Barossa and Pikka online in 2026.
2006-2008: Expansion, a failed bid and the GLNG deal
In 2006 Santos reported record 2005 revenue of $2.46 billion and set out a 25-well, $225m exploration program. Many wells were abroad, and it entered Vietnam, India and Bangladesh. Results were mixed: Dua and Blackbird in Vietnam found oil, while Jeruk in Indonesia was downgraded and several wells were dry. Maleo gas began flowing in October 2006, though a pipeline failure later shut it in.
Santos bid for Queensland Gas Company at $1.26 a share, then up to about $1.80. The competition regulator said it would oppose the deal, and Santos dropped it in February 2007. It sold its US interests for US$70m. South Australia agreed to repeal the 15% single-shareholder cap. Managing Director John Ellice-Flint stepped down in March 2008, and David Knox became permanent CEO.
In May 2008 Santos sold PETRONAS 40% of its Gladstone LNG project (GLNG) for US$2.008 billion. It then ran an off-market buy-back of about A$300m. The Reindeer gas field was approved in April 2008 but deferred in December. Santos also handed its Sidoarjo mudflow interest to Minarak for US$22.5m.
2009-2011: Funding the LNG projects
In 2009 Santos raised about A$3 billion at A$12.50 a share in a 2-for-5 entitlement offer, and redeemed A$600m of FUELS securities. Shares on issue rose from about 603 million to 831 million that year. PNG LNG reached a final investment decision in December 2009, with Santos holding 13.5% after government nominees joined. Santos also bought into Gunnedah Basin coal seam gas and later acquired Eastern Star Gas.
GLNG partners were brought in: Total took 15% in 2010, then Total and KOGAS 7.5% each. Santos kept 30% and raised about A$500m at A$12.55. It also issued €1 billion of hybrid securities. GLNG reached a final investment decision in January 2011 on a US$16bn project, with Santos's share of capex at US$4.8bn. Floods and cyclones cut production guidance, and Kipper was delayed by mercury in the reservoir. Several western Australian gas discoveries, including Zola, were announced.
2012-2014: Cost rises and first LNG
GLNG's capital cost rose to US$18.5bn and PNG LNG's to US$19bn. Fletcher Finucane began producing oil in May 2013. Browse Basin gas discoveries followed at Crown, Bassett West and Lasseter. In April 2013 S&P began treating the hybrid as debt. PNG LNG shipped its first cargo in May 2014, and Santos introduced a progressive dividend policy. In December 2014 the oil price fall led Santos to cut 2015 capex by 25% and lose its BBB+ rating, which S&P cut to BBB.
2015-2017: Collapse in oil prices and reset
Santos reported a 2014 net loss of A$935m after A$1.56bn of impairments, and a 2015 loss of A$2.7bn. GLNG produced first LNG in September 2015. Santos rejected a Scepter Partners offer at A$6.88 a share. A strategic review then produced a A$3.5bn debt-reduction plan: a A$2.5bn entitlement offer at A$3.85, a A$500m Hony Capital placement and the A$520m Kipper sale. Shares on issue nearly doubled, from about 983 million to 1.77 billion. Kevin Gallagher replaced David Knox as CEO.
In 2016 a further US$1.5bn GLNG impairment came with a five-core-asset strategy. A A$1.04bn placement at A$4.06 and a share purchase plan raised about A$1.24bn. Dividends were suspended. In 2017 Santos redeemed its euro hybrid and issued US$800m of bonds. It also signed a relationship with shareholders ENN and Hony, who held 15.1%.
2018-2020: Harbour, Quadrant and Barossa
Harbour Energy offered up to US$5.21 a share in 2018, and the board rejected it. Santos sold its Asian assets to Ophir for US$221m and paid US$1.93bn for Quadrant Energy, adding the Dorado oil discovery. Dividends resumed in August 2018, and 2018 underlying profit was a record US$727m. In 2020 Santos completed the ConocoPhillips northern Australia purchase for US$1.265bn. COVID-19 prompted a 38% capex cut and a US$25/bbl breakeven target, and impairments followed.
2021-2024: Oil Search and project delivery
Barossa reached a US$3.6bn final investment decision in March 2021. The merger with Oil Search, at 0.6275 Santos shares per Oil Search share, became effective in December 2021 and left Santos holders with about 61.5%. Share count stayed near 2.08 billion across 2017 to 2021 in the feed, so no change is narrated. Santos sold 12.5% of Barossa to JERA for US$327m and approved Pikka Phase 1. It bought back US$700m of shares in 2022 and reported 2022 free cash flow of US$3.64bn.
Court challenges over Tiwi consultation delayed Barossa, and Santos prevailed in January 2024. Preliminary talks with Woodside ended in February 2024. Santos sold 2.6% of PNG LNG to Kumul, cutting its stake to 39.9%, and transferred 16% of Bayu-Undan to TIMOR GAP.
2025-2026: Takeover bid, first LNG and first oil
In June 2025 the XRG Consortium proposed US$5.76 a share. It withdrew in September, citing timing, regulatory risk and a domestic gas commitment. Barossa received first gas in September 2025 and loaded its first LNG cargo on 25 January 2026, within budget, about six months late. Fluor paid A$1.073bn after the GLNG court judgment, with Santos's net share about A$240m. Fluor's appeal was due to be heard in July 2026, and some funds may need to be returned.
Pikka produced first oil on 18 May 2026 and was about 40,000 bbl/d gross by 2 September. Santos set a net debt reduction target of about US$2.5bn by 2030 and a roughly 10% headcount cut. A 200 PJ South Australian gas agreement was signed in June. In the first half of 2026, Santos reported production of 45.6 mmboe, underlying profit of US$397m and gearing of 23.2%. It declared an 11.6c interim dividend. No takeover bid is outstanding.
