[Form 4] RYERSON HOLDING CORPORATION Insider Trading Activity

Rhea-AI Filing Summary

Ryerson Holding Corporation (RYI) – Form 4 insider filing

Chief Operating Officer Michael Burbach reported three separate awards of dividend-equivalent restricted stock units (RSUs) on 18 Jun 2025. These RSUs automatically accumulate when cash dividends are paid on previously granted, unvested RSUs and carry no cash cost to the insider.

• 37.201 RSUs tied to the March 31 2023 grant; vesting 31 Mar 2026.
• 51.974 RSUs tied to the March 31 2024 grant; vesting 31 Mar 2026-2027.
• 20.222 RSUs tied to the March 31 2025 grant; vesting 31 Mar 2026-2028.

Total additional RSUs: 109.397, increasing Burbach’s direct holdings within each referenced award tranche to 4,116.411; 5,750.995; and 2,237.529 units, respectively. No common shares were sold, and the transaction code is “A” (acquired) with a stated price of $0, indicating purely stock-settled, dividend-equivalent accruals.

The filing is routine, aligns management incentives with shareholders, and does not materially change Ryerson’s share count or insider ownership structure.

Insights

Corporate Governance Expert

TL;DR: Routine dividend-equivalent RSUs; no cash trades; neutral impact.

The Form 4 shows automatic accrual of 109.397 RSUs to COO Michael Burbach. Because these units stem from previously disclosed grants, there is no change to Ryerson’s fully-diluted share count beyond the de minimis incremental shares already contemplated in equity-compensation plans. Absence of dispositions suggests continued insider confidence, but the low magnitude (<0.001% of shares outstanding) renders the event immaterial for valuation or governance risk. Investors should treat this as standard maintenance reporting rather than an indicator of management sentiment.
