benefits of the 2025 Buy‑Back for Investors

1. Immediate earnings accretion – Fewer shares translate into higher EPS, supporting valuation multiples.
2. Shareholder confidence signal – Management’s willingness to allocate cash to equity repurchase demonstrates belief that the stock is undervalued.
3. Flexibility for future capital allocation – With a leaner capital structure, Lundin can more readily fund exploration projects, joint‑venture opportunities, or dividend increases.
4. Tax‑efficient return – In jurisdictions where capital gains are taxed favorably, buy‑backs can be more tax‑effective than dividends.

Practical Tips for Investors Monitoring Lundin Mining

• Track EPS trends: Post‑buy‑back EPS growth can hint at enduring profitability improvements.
• Watch cash‑flow statements: Ensure the company retains sufficient free cash flow to support ongoing operations and future buy‑backs.
• Assess dividend outlook: Lundin’s historical payout ratio (≈ 55 % of net income) suggests potential for dividend growth now that equity has been reduced.
• Monitor commodity exposure: Copper,zinc and gold price movements still drive underlying earnings,so keep an eye on global metal price forecasts.

Real‑World Example: Quarterly Performance Post‑Buy‑Back

Quarter	Net Income (US $M)	EPS (US $)	Dividend per Share (US $)	Copper Price (US $/lb)
Q1 2026	312	1.80	0.28	4.12
Q2 2026	295	1.73	0.29	4.05
Q3 2026	310	1.78	0.30	4.18

– The EPS uplift reflects the reduced share count rather than a dramatic swing in net income,confirming the mechanical effect of the buy‑back.

• Dividend per share has risen modestly each quarter, aligning with the company’s policy of returning cash to shareholders while maintaining a robust balance sheet.

Future Outlook for Lundin Mining’s Capital Management

• Potential for a secondary buy‑back: Management indicated that if cash flow remains strong and the share price stays below intrinsic value,a second $100 million repurchase could be considered in 2027.
• Strategic acquisitions: with a leaner equity base, Lundin is better positioned to negotiate equity‑linked acquisitions in the copper‑zinc corridor of South America.
• Debt reduction path: The company plans to allocate ~US $40 million of the remaining 2025 cash flow to partially retire its revolving credit facility, improving leverage ratios.

Key Takeaways for Stakeholders

• The $150 million 2025 share‑buyback successfully reduced Lundin Mining’s share capital,delivering immediate EPS betterment and boosting shareholder value.
• Market response and analyst upgrades underscore the positive perception of the repurchase.
• Ongoing cash‑flow discipline, coupled with strategic commodity exposure, positions Lundin to enhance dividends and consider further capital‑return initiatives.
