Industry Context

This filing reflects a routine disclosure by a major asset manager, BlackRock, regarding its passive investment in Olin Corp. Such large institutional holdings are common across various industries, including the chemicals and ammunition sectors where Olin operates, and typically signal a long-term investment horizon rather than an active attempt to influence corporate strategy.

Comparison to Industry Standards

• BlackRock's 9.1% stake in Olin Corp is a substantial passive holding, consistent with the investment strategies of large asset managers like Vanguard, State Street, or Fidelity, which often hold significant, non-controlling stakes across a broad portfolio of publicly traded companies.
• For example, similar passive stakes are observed in other industrial chemical companies such as Dow Inc. or LyondellBasell Industries, where major index funds and ETFs hold significant portions of outstanding shares.
• The certification that the shares are held in the ordinary course of business and not for control purposes aligns with the typical passive investment mandate of Schedule 13G filers, differentiating it from activist investor filings (Schedule 13D).

Corporate Governance

Stakeholder Impact

• Shareholders: The disclosure of a significant passive stake by BlackRock may provide a degree of stability and confidence, as it indicates a major institutional investor's continued interest in Olin Corp.
• Management: Confirms that a large institutional investor is not seeking to influence control, allowing management to focus on long-term strategic execution without immediate activist pressure from this specific shareholder.

Next Steps

• Olin Corp will continue its operations.
• BlackRock, Inc. will continue to hold its investment in Olin Corp in the ordinary course of business.
• BlackRock, Inc. will file future amendments to Schedule 13G if its beneficial ownership percentage changes significantly (e.g., crosses 1% thresholds up or down) or if its investment intent changes.
