Tamboran Resources (ASX:TBN) Could Be 36% Undervalued Following Earnings And Auditor Warning

Simply Wall St · 4d ago

Why Tamboran Resources Earnings And Auditor Warning Matter Now

Tamboran Resources (ASX:TBN) has landed in focus after releasing full year results alongside a stark auditor warning about its ability to continue as a going concern, a combination that sharply concentrates investor attention.

The latest A$0.24 Tamboran Resources share price comes after a mixed stretch where the 30 day share price return declined 12.73%. However, the 90 day gain of 11.63% and year to date rise of 20% suggest momentum has been building over the medium term, while the 3 year total shareholder return of 74.71% contrasts with a weaker 5 year total shareholder return of 34.78%. This shows how sentiment has shifted as investors weigh narrower losses against the fresh going concern warning.

Tamboran Resources trades at a steep discount to analyst targets after a recent share pullback. Is that a genuine mispricing, or a rational response to the going concern flag and ongoing losses?

Most Popular Narrative: 36% Undervalued

Tamboran Resources is framed as undervalued in the most followed narrative, with a fair value of A$0.38 against the A$0.24 last close. This comparison puts the spotlight on how quickly the Beetaloo project can move from concept to contracted gas sales.

Progress towards first gas from the Beetaloo Basin Pilot Area in the third quarter of calendar 2026, supported by an 88% complete compression facility and an APA owned pipeline in final commissioning, is expected to move Tamboran Resources from a pre revenue phase toward contracted gas sales. This is likely to affect revenue visibility and cash flow generation.

Another View On Tamboran Resources Valuation

The first narrative paints Tamboran Resources as 36% undervalued against analyst fair value. A different lens tells a cooler story. On a P/B of 1.7x, the stock is described as expensive versus both the Australian Oil and Gas group at 1.4x and its peer average of 1.7x. That points to limited cushion if expectations reset.

Investors weighing these mixed signals may want to stress test their own assumptions on Beetaloo timing, funding costs and future returns before leaning on any single price target. See what the numbers say about this price — find out in our valuation breakdown.
