AU vs. KGC: Which Gold Mining Stock is the Better Buy?

Gold prices have advanced 26% year-to-date despite a recent retreat, supported by safe-haven demand and central bank buying. In this environment, AngloGold Ashanti (AU) reported robust Q2 2025 results, including a 21% production increase and 78% revenue growth, while Kinross Gold (KGC) posted a 41.7% revenue jump and an 87% surge in free cash flow. Despite strong performance from both, the analysis favors Kinross Gold as the superior investment due to its stronger six-month stock gains, robust project pipeline, and more favorable earnings growth outlook, earning it a Zacks Strong Buy rating over AngloGold Ashanti's Hold rating.

Analysis

Both AngloGold Ashanti (AU) and Kinross Gold (KGC) are capitalizing on a strong gold market, which has seen prices advance 26% year-to-date to $3,320 per ounce. AngloGold demonstrated significant operational growth in Q2 2025, with production increasing 21% to 804,000 ounces, largely due to its Sukari mine acquisition. This drove a 78% surge in revenue to $2.4 billion and a 149% increase in free cash flow to $535 million, alongside a substantial 92% reduction in net debt. However, this growth was accompanied by rising costs, with all-in-sustaining costs (AISC) increasing 7% to $1,666 per ounce, and the company projects flat production levels for 2026, with analyst estimates indicating a potential 7.12% earnings dip. In contrast, Kinross Gold generated record free cash flow of $647 million, an 87% year-over-year increase, on revenues that rose 41.7% to $1.73 billion, despite a 4.3% dip in quarterly production. KGC's superior six-month stock performance of 70.5% versus AU's 64.8%, combined with a more favorable earnings outlook that includes a 2.22% growth estimate for 2026 and upwardly trending analyst revisions, suggests a stronger investment case despite its higher forward P/E multiple of 13.40x compared to AU's 11.01x.

Key Decisions for Investors

• Given its stronger stock performance, positive earnings estimate revisions, and projected earnings growth into 2026, Kinross Gold appears to be the more compelling investment for capturing continued momentum in the gold sector.
• Investors considering AngloGold Ashanti should closely monitor its ability to manage rising all-in-sustaining costs, which reached $1,666 per ounce, and any updates to its flat 2026 production guidance, as these are key risks to its valuation.
• While both companies are highly levered to gold prices, the choice between them represents a trade-off between KGC's consistent operational performance and growth outlook versus AU's aggressive M&A-fueled growth strategy, which currently faces higher cost pressures and future production uncertainty.
• The valuation premium on KGC, with a forward P/E of 13.40x versus AU's 11.01x, appears justified by its superior growth prospects, but a significant downturn in gold prices would negatively impact margins and cash flow for both entities.
