Northern Star Resources Ltd (ASX: NST) shares are being hit hard today, even though gold prices remain near record highs.
The Northern Star share price has dropped 8.78% to $26.08 following the release of the company's December quarter update. That sell-off comes despite the stock still being up 53% over the past year.
Let's take a look at the headline results and why the top-tier gold miner's shares fell today.
Why Northern Star shares fell
Northern Star reported gold sales of 348,062 ounces for the quarter at an all-in sustaining cost (AISC) of $2,937 per ounce. That AISC figure was higher than expected and reflected a series of one-off operational issues across several sites.
Management said production was hit by a crusher failure at Kalgoorlie and unplanned downtime at Thunderbox. Lower grades at the Pogo mine, as it moved into new mining areas, also weighed on results.
While many of these issues have since been resolved, the weaker quarter forced the company to revise full-year guidance.
The guidance cut that worried the market
For FY26, Northern Star now expects gold sales of 1.6 to 1.7 million ounces, down from its prior range of 1.7 to 1.85 million ounces. Cost guidance was also lifted, with AISC now forecast at $2,600 to $2,800 per ounce.
That change was enough to knock confidence in the short term. Investors appear to be reacting to weaker near-term numbers, rather than reassessing the company's longer-term outlook.
Strong balance sheet remains a key positive
For long-term investors, the key question is whether this update affects the company's long-term outlook.
On that front, Northern Star still looks well-positioned. The company ended December with $1.176 billion in cash and bullion, remained in net cash, and generated $328 million in underlying free cash flow, even after heavy growth spending.
Management expects production to improve in the second half as recent issues are resolved. Major projects, including the KCGM mill expansion, are also continuing to move forward.
So, is this a buying opportunity?
Today's sell-off looks driven by short-term disappointment, not long-term damage to the company's underlying fundamentals.
Northern Star still owns long-life gold assets, has a strong balance sheet, and benefits from gold prices near record highs.
For investors who believe gold prices will stay strong, this pullback may offer an excellent buying opportunity. The key is to be comfortable with short-term ups and downs along the way.
