Century Aluminum's Strategic Debt Financing and Its Implications for Growth and Shareholder Value

Century Aluminum's recent strategic refinancing and capital allocation decisions underscore a disciplined approach to balancing debt management with long-term growth. By leveraging capital efficiency and extending debt maturities, the company has positioned itself to navigate industry volatility while signaling confidence in its operational stability and shareholder returns.

Refinancing for Cost and Maturity Optimization

In 2025, Century Aluminum executed a pivotal refinancing maneuver, issuing $400 million in 6.875% Senior Secured Notes due 2032. This move allowed the company to redeem $250 million of its 7.50% Senior Notes due 2028, reducing its interest rate by 63 basis points and extending the maturity by four years Century Aluminum (CENX) Completes US$395 Million Debt Financing^[2]. The net proceeds also repaid borrowings under existing credit facilities, bolstering liquidity and strengthening the balance sheet Century Aluminum (CENX) Completes US$395 Million Debt Financing^[2].

Complementing this, Century amended its credit facility to extend its maturity to July 2030, with adjustments to swingline loans and customer concentration limits for major clients like Alcoa Corporation and Brazeway, LLC Century Aluminum (CENX) Completes US$395 Million Debt Financing^[2]. These actions collectively improved the company's debt maturity profile, lowering its cost of capital and mitigating refinancing risks in a high-interest-rate environment.

Capital Allocation: Debt Reduction and Liquidity Targets

Post-refinancing, Century Aluminum has prioritized reducing net debt and enhancing liquidity. As of Q1 2025, total debt fell to $487 million from $530 million, while net debt dropped to $442 million from $497 million Century Aluminum Q1 2025 slides: Mixed results amid strategic expansion plans^[1].

This phased approach balances short-term financial prudence with long-term value creation, ensuring operational flexibility to capitalize on growth opportunities.

Fueling Growth and Shareholder Value

Recent debt financing has also enabled Century Aluminum to pursue strategic growth initiatives. A $395 million debt issuance in 2025 provided the financial flexibility to restart the Mt.

These investments align with the company's focus on expanding domestic aluminum production, a sector poised for long-term demand driven by decarbonization and infrastructure trends.

By aligning capital allocation with operational stability, Century Aluminum is not only reducing its financial leverage but also positioning itself to capture market share in a recovering industry. The company's liquidity buffer and extended debt maturities provide a safety net, allowing it to invest in growth without compromising its credit profile.

Conclusion

Century Aluminum's strategic refinancing and capital allocation reflect a nuanced understanding of capital efficiency and long-term stability. By lowering interest costs, extending maturities, and targeting disciplined shareholder returns, the company is building a resilient foundation for growth. Investors should view these moves as a signal of confidence in the company's ability to navigate macroeconomic challenges while delivering value through both operational expansion and financial prudence.
