Record EBITDA, rising costs in Aura Minerals (NASDAQ: AUGO) 2025 update

Rhea-AI Filing Summary

Aura Minerals reports record operating results for Q4 and full-year 2025 while posting an accounting net loss driven by hedge marks. Q4 production reached 82.1k gold-equivalent ounces (GEO), up 23% year over year, with 2025 production of 280.4k GEO, landing in the upper half of guidance.

Adjusted EBITDA hit a record US$207.9 million in Q4 and US$547.8 million for 2025, but non-cash mark-to-market losses of US$81.7 million on gold collars drove a Q4 net loss of US$20 million and full-year net loss of US$80.8 million. Excluding these, adjusted net income was positive at US$73 million in Q4 and US$206 million for 2025.

Recurring free cash flow reached US$96 million in Q4 and US$256 million for the year, helping end 2025 with net debt of US$117.6 million, or 0.3x last-twelve-month EBITDA, even after acquiring Mineração Serra Grande and funding growth projects. Safety performance remained strong, with 18 consecutive months without lost-time incidents.

At the Borborema project, reserves increased to 1.5 million ounces, supporting a new feasibility study with an after-tax NPV of US$612.5 million and IRR of 42.8%. For 2026, Aura guides production up to 340–390k GEO but expects higher all-in sustaining costs, mainly from integrating MSG, higher metal prices, and mine sequencing.

Positive

• Record operating performance and cash generation: Q4 2025 adjusted EBITDA reached US$207.9 million and recurring free cash flow was US$96 million, with full-year adjusted EBITDA of US$547.8 million and free cash flow of US$256 million, supported by record GEO production.

• Growth with low leverage and reserve expansion: 2025 production of 280.4k GEO was in the upper half of guidance, while year-end net debt was US$117.6 million, just 0.3x LTM EBITDA. Borborema reserves increased to 1.5 million ounces, underpinning an after-tax NPV of US$612.5 million and IRR of 42.8%.

Negative

• Hedge impacts mask profitability in reported earnings: Mark-to-market losses of US$81.7 million on gold collars in Q4 2025 led to a quarterly net loss of US$20 million and full-year net loss of US$80.8 million, despite positive adjusted net income.

• Cost structure guided higher for 2026: 2026 AISC guidance of US$1,488–US$1,601 per GEO exceeds 2025’s US$1,458, attributed to MSG integration, higher metal prices, mine sequencing, and expansion activities, which could pressure future margins if gold prices or grades soften.

Insights

Mining equity analyst

Record cash generation and growth, but hedge losses and rising costs complicate the picture.

Aura Minerals delivered six straight quarters of record adjusted EBITDA, reaching US$208 million in Q4 2025 and US$548 million for the year. Production of 280k GEO landed in the upper half of guidance, while recurring free cash flow of US$256 million and net debt of US$117.6 million (0.3x LTM EBITDA) point to a solid balance sheet.

However, hedge mark-to-market effects are material. Non-cash losses of US$81.7 million on gold collars in Q4 drove a reported quarterly net loss of US$20 million and full-year net loss of US$80.8 million, despite adjusted net income of US$206 million for 2025. This creates a gap between accounting earnings and underlying operating strength.

Looking ahead, 2026 production guidance of 340–390k GEO represents potential growth of roughly 20–36% versus 2025, helped by the MSG acquisition and Borborema’s first full year. Yet AISC guidance of US$1,488–US$1,601 per GEO, above 2025’s US$1,458, reflects higher-cost MSG ounces, metal price assumptions, and mine sequencing. Subsequent disclosures and quarterly results may clarify how quickly integration, strip phases, and expansion projects translate into sustainable margins within the guided cost range.

FAQ

How did Aura Minerals (AUGO) perform operationally in Q4 2025?

Aura Minerals delivered record quarterly production of 82.1k gold-equivalent ounces in Q4 2025, up 11% from Q3 and 23% from Q4 2024. Full-year 2025 production reached 280.4k GEO, landing in the upper half of the company’s 266k–300k GEO guidance range.

What were Aura Minerals (AUGO) key financial results for 2025?

Adjusted EBITDA reached US$207.9 million in Q4 and US$547.8 million for 2025, supported by strong production and margins. Recurring free cash flow was US$96 million in Q4 and US$256 million for the year, helping reduce net debt to US$117.6 million by year-end.

Why did Aura Minerals (AUGO) report a net loss in 2025 despite strong EBITDA?

The company’s 2025 net loss of US$80.8 million mainly reflects non-cash mark-to-market losses on gold hedge collars, including US$81.7 million in Q4. Excluding these derivative impacts, Aura reported positive adjusted net income of US$73 million in Q4 and US$206 million for the full year.

What production and cost guidance did Aura Minerals (AUGO) give for 2026?

For 2026, Aura guides consolidated production to 340k–390k gold-equivalent ounces, above 2025’s 280k. All-in sustaining costs are expected at US$1,488–US$1,601 per GEO, higher than 2025’s US$1,458, reflecting MSG integration, metal prices, mine sequencing, and expansion spending.

How strong is Aura Minerals (AUGO) balance sheet after 2025?

Aura ended 2025 with net debt of US$117.6 million, equal to 0.3x last-twelve-month adjusted EBITDA. This low leverage came despite completing the Mineração Serra Grande acquisition, funding Borborema and other growth projects, and paying dividends, supported by robust free cash flow and Nasdaq IPO proceeds.

What are the latest developments at Aura Minerals’ (AUGO) Borborema project?

Borborema’s mineral reserves increased to 1.5 million ounces, following approval to relocate a road that unlocked an additional 670 koz. An updated feasibility study shows an after-tax NPV of US$612.5 million and IRR of 42.8%, with an estimated 20.5-year mine life and average 65 koz annual production.

How is Aura Minerals (AUGO) performing on safety and operational stability?

Aura reported 18 consecutive months without lost-time incidents across all operations and projects, including more than 1,250 days without an LTI at Borborema. Independent consultants confirmed satisfactory stability for all dams, waste dumps, and heap leach pads, with Brazilian tailings dams receiving required stability declarations in December 2025.
