## Record profits, falling stock
Sibanye Stillwater reported record H1 2026 results with adjusted EBITDA surging 111% to R31.8 billion, yet the stock fell 29.3% in Q2, revealing a disconnect between operational performance and market valuation.
## Revenue surge driven by prices
H1 2026 revenue jumped 64% to R90 billion, but this was almost entirely due to higher precious metals prices, not production growth. South African PGM output actually fell 2% while gold production declined 2%.
## Rising costs squeeze margins
All-in sustaining costs for SA PGM operations jumped 10% to R26,252 per ounce, driven by higher royalties and inflation. Gold AISC rose 14% to R1,638,089 per kilogram, reflecting elevated pumping costs and shaft maintenance.
## Balance sheet strengthens
Gross debt fell 18% to R32.1 billion while net debt to adjusted EBITDA improved to 0.18x. The company generated R14.5 billion in free cash flow and declared an interim dividend yielding approximately 8%, among the highest in the peer group.
## Valuation discount vs peers
Sibanye trades at 5.8x EV/EBITDA versus a peer average of 12.2x, and at 0.96x price-to-NAV versus 1.75x for peers. This discount reflects market skepticism about earnings sustainability and execution risk.
## U.S. mechanization carries risk
The company's U.S. mechanization strategy aims to lower all-in sustaining costs toward $1,000 per ounce, but carries acknowledged execution risk. Stillwater West was removed from the five-year plan until cost targets are met.
## Electricity costs rising fast
CEO Richard Stewart noted that electricity costs at Driefontein increased 13% following regulatory adjustments, representing a significant ongoing cost pressure that could undermine the mechanization strategy.

## What to watch next
Monitor whether commodity prices hold, if the mechanization strategy achieves cost targets, and whether debt reduction continues. The current valuation may offer value if execution improves in H2 2026.
## Key takeaway

Sibanye's record H1 2026 results were driven almost entirely by higher precious metals prices, not operational improvements, leaving the stock vulnerable if commodity prices normalize.
