New Zealand energy firm Mercury NZ (ASX:MCY) has raised its earnings guidance for the 2026 financial year, citing a robust increase in renewable energy production.

The company upgraded its forecast EBITDAF (earnings before interest, tax, depreciation, amortisation, and fair value movements) from $1 billion to $1.05 billion.

The revision is largely attributed to higher-than-anticipated output from its hydro schemes and newly commissioned generation assets, paired with what the board described as "disciplined portfolio management".

While the outlook is optimistic, Mercury cautioned that the updated guidance remains contingent on hydrological conditions and potential unforeseen one-off expenses throughout the remainder of the fiscal year.
