Why are Santos shares climbing higher?
Santos shares have trended higher through 2026 so far as recurring tensions between the US and Iran continue to fuel concerns over global oil supplies and supported energy prices.
The shares spiked in February and March, around the time news first broke that conflict had escalated between the two nations. The shares continued climbing in value as the war heated up.
Rising oil prices were the main tailwind for Santos shares, as tight oil supply made prices highly volatile.
But every time there is renewed optimism about a potential US-Iran peace agreement, the price of oil softens, and the Santos share price follows suit. In June and July the share price tumbled before rebounding again over the past month.
In mid-August, after the company posted its half-year FY26 results, Santos shares reached a multi-year high of $8.45 a piece.
The company reported a 2% year-on-year increase in sales revenue to US$2.62 billion. Production volumes were also higher, up 1.7% to 48 million barrels of oil equivalent (mboe).
But Santos also posted a 19% decline in its half-year statutory net profit after tax (NPAT), which fell to US$355 million.
Santos also managed to generate free cash flow from operations from its strong base business performance.
The company is well placed to increase its production in the coming reporting periods, which could help boost earnings.
