Santos shares just hit a four-year high. Here’s why they could keep rising.

Santos Ltd (ASX: STO) shares reached a four-year high last Friday, and are up around 28% for the year to date.

On Tuesday, the company held its annual Investor Briefing Day in Sydney.

The headlines coming out of that event did not disappoint.

Here is what investors need to know about the Santos shares story right now.

Three things Santos told the market

The Briefing Day centred on three key messages.

First, the Barossa LNG project is currently producing at 75% of its planned 2026 production rates, with plateau production targeted before year end.

This is the most important near-term earnings driver Santos has, and it is tracking on schedule.

Second, management outlined a cost reduction framework targeting higher free cash flow margins as production grows.

Third, Santos confirmed first oil from its Pikka Phase 1 development in Alaska in late May 2026, with ramp-up expected to continue over the coming weeks.

Together these milestones mark a clear shift.

Santos is moving away from being a company spending heavily on major capital projects to one collecting the returns from them.

That transition is exactly what investors have been waiting for.

The oil price is doing the rest

Oil prices surged above US$105 per barrel in 2026 on Middle East tensions.

Every dollar rise in the oil price flows almost directly into Santos’ revenue.

In Q1 2026, Santos reported sales revenue of $1.27 billion, up 3% on the prior quarter, driven by stronger crude oil prices and higher LNG volumes.

Management reaffirmed full-year production and cost guidance, which removed a key uncertainty investors had been watching.

But the shares pulled back on Tuesday

Despite the positive Briefing Day content, Santos shares fell 5% from their four-year high by Tuesday afternoon.

This has been attributed the move to profit-taking and a cooling oil price as markets began pricing in a possible US-Iran peace deal.

Oil prices dropped more than 6% on Monday on that news.

For context, Santos shares are still up more than 22% over the past twelve months even after Tuesday’s retreat.

The key risk

A US-Iran peace deal would reopen the Strait of Hormuz and push oil prices materially lower.

This is the single biggest near-term risk to the Santos investment thesis.

As a result, investors should watch Middle East developments closely.

Foolish takeaway

Santos shares are not as cheap as they were.

But a world-class LNG portfolio finally converting major capital projects to cash flow, an oil price above $100, and confirmed first production from Alaska is a powerful combination.

For investors who believe energy prices stay elevated, Santos remains one of the more interesting energy stories on the ASX today.
