Aura Minerals Announces Mining Fleet Insourcing at Apoena, Almas and Borborema

Part of the acquisition consideration is tied to performance during the transition period.

Rhea-AI Summary

Aura Minerals (AUGO) signed a definitive agreement to acquire Newco and bring mining fleet operations in-house at three Brazilian gold operations. Newco will hold the fleet, equipment leases and dedicated workforce serving Apoena, Almas and Borborema. The transition is targeted for January 2027.

The acquisition's enterprise value is R$612 million (approximately US$118 million), with up to R$250 million paid in cash and the remainder comprising assumed equipment lease financing and contingent payments. Some consideration depends on transition performance. Aura expects a weighted-average reduction in all-in sustaining costs of US$150 to US$200 per ounce of gold sold across the three operations beginning in 2027, based on internal estimates. Closing requires Brazilian antitrust clearance from CADE.

How this balance works

Rhea-AI gives every point it takes from this document a weight. Minor counts 1, Moderate 3 and Major 9, so one Major point outweighs several Minor ones. The bar adds up the weights on each side, and when neither side holds more than 65% of the total the balance reads Mixed.

It reads the document as published, with the same rules for every company, and it does not look at what the market expected or at how the stock traded, so a point can be objectively good on a day the stock falls.

Rhea-AI Sentiment measures something else, the tone of the wording.

enterprise value financial

"The agreed consideration for the acquisition (the “Enterprise Value”)"

Enterprise value is the total worth of a company, reflecting what it would cost to buy the entire business. It includes the company's market value plus any debts, minus its cash holdings, offering a comprehensive picture of its true value. Investors use it to compare companies regardless of their capital structures, helping them assess how much they would need to pay to acquire the business.

View in glossary

all-in sustaining costs (aisc) technical

"reduce all-in sustaining costs (AISC) by US$150 to US$200 per ounce"

All-in sustaining costs (AISC) is a per-unit measure that shows the total ongoing cost to keep a producing asset running, including operating expenses, routine maintenance, sustaining capital, and a share of corporate and administrative costs. For investors it provides a more complete picture than simple production cost numbers—think of it as the full monthly bill to maintain a business divided by its output—helping compare profitability and cash flow durability across producers.

antitrust clearance regulatory

"including antitrust clearance from Brazil's Administrative Council"

Antitrust clearance is approval from government competition authorities that a proposed merger, acquisition or business practice won’t substantially reduce competition in a market. It matters to investors because clearance determines whether a deal can proceed as planned, may be delayed, require changes, or be blocked — like needing a permit before combining two neighboring yards — and therefore affects expected value, timing and risk for shareholders.

ROAD TOWN, British Virgin Islands, Oct. 02, 2026 (GLOBE NEWSWIRE) -- Aura Minerals Inc. ("Aura" or the "Company") (NASDAQ: AUGO | B3: AURA33) announced today that it has signed a definitive agreement to acquire a company (“Newco”) that will hold the mining fleet, related equipment leases and dedicated workforce currently operated by a third-party contractor in three of its gold operations in Brazil — Apoena, Almas and Borborema — and to bring fleet operation and maintenance in-house (the "Insourcing"), with the transition targeted for January 2027. At MSG, the Company already operates the mine fleet directly.

The Insourcing is expected to give Aura greater operational control and to generate synergies across its Brazilian business units. The timing is aligned with the Company's growth in the country where it currently operates four gold mines and plans to expand production capacity in some of its operations. The Insourcing will give Aura direct control over fleet sizing, maintenance strategy and utilization at all three operations, and is expected to improve equipment availability and reliability and lower mining unit costs over time.

The agreed consideration for the acquisition (the “Enterprise Value”) is R$612 million (approximately US$118 million¹), of which up to R$250 million will be paid in cash, with the remainder consisting of the assumption of existing equipment lease financing and the retention of other contingent payments typical for this type of transaction. The transaction structure is designed to align the seller with a smooth transition, with a portion of the consideration subject to performance during the transition period. As part of the transaction, Aura will also absorb the existing workforce dedicated to fleet operation and maintenance at the three operations, ensuring continuity and avoiding disruption to operations after the acquisition is completed.

Based on the Company’s internal estimates, the Insourcing is expected to reduce all-in sustaining costs (AISC) by US$150 to US$200 per ounce of gold sold, on a weighted-average basis across the three operations, beginning in 2027².

The Insourcing will give Aura direct control over fleet sizing, maintenance strategy and utilization at all three operations, and is expected to improve equipment availability and reliability and lower mining unit costs over time. Both the transition and the ongoing management of the Newco will be led by a new dedicated team with experience in managing mine fleet operations.

Closing of the transaction is subject to customary conditions precedent, including antitrust clearance from Brazil's Administrative Council for Economic Defense (CADE).

Rodrigo Barbosa, CEO and President, commented: "Over the past three years, we have grown from one operation in Brazil to four, including MSG, which we acquired with its own mine fleet already in place. Insourcing the mine operations is a natural next step in that growth strategy and in our ongoing focus on cost reduction. The Insourcing is expected to deliver a robust return on invested capital through an average AISC reduction of US$150 to US$200 per ounce across our three open-pit mines, while giving us greater operational control to pursue further productivity gains and economies of scale."

² Expected AISC reduction on weighted average basis of the three operations. AISC is a non-IFRS measure and does not have a standardized meaning within IFRS and therefore may not be comparable to similar measures presented by other companies. The Company does not provide a reconciliation of forward-looking AISC to the most directly comparable financial measure calculated and presented in accordance with IFRS because such reconciliations cannot be provided without unreasonable effort and such information is not available given the difficulty of projecting event-driven transactional and other non-core operating items in any future period.
