Nittetsu Mining Co., Ltd. Full-Year Earnings Call Flash

Arqueros mine to commence operations in Jul-Sep, doubling copper production by FY27; JPY 10B share buyback and cross-shareholding reduction aimed at sustaining PBR above 1.0x

PublishedMay 15, 2026 at 20:05 GMT+9

Summary

FY25 marked record highs with revenue of JPY 209.7B (+6.6%) and operating income of JPY 18.8B (+83.3%). Key contributors were higher copper prices and lower production costs in the metals segment (mining), along with real estate disposal gains. For FY26, the company guides operating income of JPY 14.0B (▲25.5%) due to increased growth investment, cost front-loading at Arqueros mine, and the absence of real estate disposal gains. However, a JPY 10B treasury share acquisition and accelerated reduction of cross-shareholdings will drive balance sheet optimization. In FY27, the dual-mine structure with Arqueros mine reaching full contribution is expected to expand earnings, with the formulation of the 4th Mid-Term Plan set to accelerate corporate value enhancement.

Key Points (Earnings Highlights and Growth Actions)

  • Management Strategy and Market Positioning
    • PBR reached 1.24x in FY25; the company has outlined initiatives targeting both ROE and PER to sustain and further improve this level
    • Copper mining positioned as a priority investment area, with exploration projects spanning South America, North America, the Pacific, Africa, and the Middle East. Regular monitoring and periodic portfolio reviews are being conducted
    • Ahead of the 4th Mid-Term Plan (FY27~), the company is considering disclosing ROE targets and an optimal capital structure
  • Current Business Progress and Drivers
    • At Atacama mine, useful lives of key equipment were extended in line with increased mineable reserves, reducing depreciation and contributing to higher earnings
    • Operations at a new mining area at Atacama mine were temporarily suspended, and the resulting reduction in contractor costs was one factor behind lower production costs (non-recurring)
    • Smelting achieved higher profits despite worsening ore-purchasing terms, supported by improved by-product income and favorable yen depreciation
    • Politesu recorded revenue growth on price revisions and demand increases, though rising raw material costs toward the fiscal year-end offset profit gains
  • Strategic Initiatives and Inflection Points
    • Resolved to acquire up to JPY 10B (cap of 5M shares) in treasury shares with full cancellation, clearly signaling commitment to capital efficiency improvement
    • Signed participation agreement for the Oracle Ridge copper exploration project (Arizona, USA), the company's first copper mining venture in North America
    • Established a JV with Electric Power Development (J-POWER) for Shiramizugoe geothermal power generation (51% stake), building a stable medium- to long-term earnings base
    • Decided to construct an overseas Politesu plant in Taiwan, launching international expansion of water treatment agents

Outlook and Strategy

  • FY26 guidance calls for revenue of JPY 232.5B (+10.9%) and operating income of JPY 14.0B (▲25.5%), assuming copper at 550¢/lb and JPY 155/USD
  • Key drivers of the FY26 earnings decline are increased growth investment including exploration costs (including ~JPY 1.0B deferred from FY25), absence of real estate disposal gains, and cost front-loading at Arqueros mine
  • Arqueros mine targets operational start-up in Jul-Sep 2026, ramping to full production within several months. By FY27, the dual-mine structure is expected to more than double current copper output
  • Atacama mine life is estimated at just under 10 years; production forecasts revised from 13,000t to 11,000t per annum, reflecting declining ore grades
  • Cross-shareholding reduction of at least JPY 10B over FY25-27 is the floor; targeting below 20% of net assets by FY27 (excluding deemed holdings)
  • FY26 total shareholder return is planned at JPY 14.8B (JPY 4.8B dividends + JPY 10B buyback), implying a total payout ratio of 124.0%

Positive Factors

  • Arqueros mine's all-in sustaining cost (C3) of 318¢/lb is highly competitive; ample profit generation capacity at the assumed copper price of 550¢/lb
  • FY25 ROIC reached 6.7% (exceeding WACC of 5.8%), with ROE at 9.4%, demonstrating tangible improvement in capital efficiency
  • Shareholder count expanded approximately 3x YoY to 20,682; average daily trading volume also improved from 248,037 shares to 636,280 shares
  • Sensitivity: every 10¢/lb increase in copper price adds JPY 450M to operating income. Structural copper demand growth (electrification, renewables) provides a tailwind
  • Limestone continues to benefit from price pass-throughs, absorbing modest volume declines; the mineral resources segment achieved three consecutive years of revenue and profit growth
  • A robust exploration pipeline is in place (Puquios, Costa de Cobre, Oracle Ridge, Fiji, Morocco, Saudi Arabia)

Concerns and Risks

  • Arqueros mine development costs increased from USD 396M to USD 486M, with operational start-up delayed by approximately three months
  • Equity ratio declined from 58.9% to 50.7%, primarily driven by a JPY 34.9B increase in long-term borrowings related to Arqueros mine development. Post-startup depreciation and interest expense warrant close attention
  • FY26 ROIC is projected at 4.2%, falling below the 5.8% WACC. Temporary downward pressure on capital efficiency until Arqueros mine reaches full contribution
  • Atacama mine faces rising costs due to aging ore body irregularity and deeper mining levels. Labor cost revisions are an additional earnings headwind
  • Tight copper concentrate supply-demand conditions are keeping TC/RC at depressed levels. Risk of further deterioration in smelting ore-purchasing terms persists
  • Continental General Insurance raised its stake to 8.58% in H1 2025, with references to the possibility of making significant shareholder proposals
