At the same time, the 3 year total shareholder return of 56.72% and 5 year total shareholder return of 120.17% show that long term holders have still seen sizeable gains.

Another View: Cash Flows Paint A Tighter Picture

While the analyst narrative points to a fair value of A$27.38 and labels Northern Star as undervalued, the Simply Wall St cash flow model is more cautious. At A$19.26, the stock sits slightly above an estimated future cash flow value of A$18.83. This suggests less of a clear bargain and more of a fine margin for error. Is the earnings story too optimistic, or is the cash flow view too conservative?
