Northern Star Shares Slide Despite Strong Cash Flow
Northern Star Resources (ASX:NST) released a solid March quarter report today, yet its shares are down 3.6% to A$22.80. The company sold 381,000 ounces of gold, generated A$301 million in free cash flow and confirmed it is still on track to meet its full-year guidance. Normally, numbers like these would push a stock higher. So why is Northern Star going the other way, and does this dip actually give long-term investors a chance to buy in at a lower price?
A Strong Quarter That Deserves a Second Look
There is plenty to like in today’s update. NST produced 381,000 ounces for the quarter, taking its nine-month total to 1.11 million ounces. It also ended the period with around A$1.2 billion in cash and bullion, a healthy buffer that gives management flexibility to keep investing, paying dividends and buying back shares.
Even better, the company’s long-awaited A$500 million share buyback is set to begin tomorrow, April 23. This is a strong signal. When management uses cash to buy its own shares, it usually means they believe the stock is trading below fair value. In our view, the quarter shows NST is back on steadier ground after a tough few months. Cash generation is strong, and production is holding up after two earlier guidance cuts this year.
So, Why Are Northern Star Shares Falling?
The market is focused on one thing: costs. Northern Star reported an all-in sustaining cost (AISC) of A$2,709 per ounce, which is at the higher end of guidance. Management also warned that Q4 costs could rise another A$75 to A$85 per ounce because of higher diesel prices linked to Middle East tensions.
On top of that, gold prices have been volatile. A weaker gold price combined with rising costs can squeeze mining margins quickly, and investors are nervous.
Our take: the reaction looks overdone. Yes, higher fuel costs are a real concern. But NST is still generating strong cash flow, sitting on a big cash pile, and its major KCGM mill expansion remains on track for early FY27. That expansion is expected to lift production and lower unit costs over time.
The Investor’s Takeaway
We believe today’s sell-off looks more like short-term nervousness than a change in the long-term story. Investors who have been waiting for a better entry point into Australia’s largest gold miner may find today’s weakness useful. For long-term investors with a two- to three-year view, Northern Star still ticks the key boxes: scale, cash generation, a disciplined capital return plan, and a clear growth project in KCGM. The buyback starting tomorrow should also provide some support at current share price levels.
The key risk to watch is oil. If diesel prices stay high, AISC will keep rising, and margins will stay under pressure. Gold prices also need to hold above the US$4,200 level to keep producer margins comfortable. For now, we see Northern Star as a quality gold stock getting cheaper on short-term noise. Patient investors may want to start building a position while the market’s focus is on costs rather than the bigger picture.
