[Form 4] RYERSON HOLDING CORPORATION Insider Trading Activity

Rhea-AI Filing Summary

Ryerson Holding Corporation (RYI) – Form 4 Insider Filing

Executive Vice President, General Counsel & Chief HR Officer Mark S. Silver reported the automatic acquisition of dividend-equivalent restricted stock units (RSUs) on 18 June 2025. The filing shows three separate RSU accruals tied to previous grants:

• 26.572 RSUs linked to the March 31 2023 grant (vests 31 Mar 2026)
• 51.974 RSUs linked to the March 31 2024 grant (vests 31 Mar 2026 & 31 Mar 2027)
• 90.285 RSUs linked to the March 31 2025 grant (vests 31 Mar 2026-2028)

The total 168.831 RSUs were acquired at $0.00 cost as part of normal dividend-equivalent adjustments; no open-market purchases or sales occurred. Following the transactions, Silver’s derivative holding rose to an aggregate 18,681.431 RSUs across the three grant lots. Ownership is reported as direct.

The activity is routine, reflects alignment with shareholder dividends, and does not alter the company’s share count.

Positive

• Officer’s beneficial ownership increased by 168.831 RSUs, indicating continued equity alignment with shareholders, albeit on a small scale.

Negative

• None.

Insights

Financial Analyst

TL;DR: Routine dividend-equivalent RSUs; slightly positive alignment, immaterial to RYI valuation.

This Form 4 shows non-cash, cost-free RSU accruals credited to EVP Mark S. Silver under existing equity grants. The 168.8 additional units (≈ $5-6k in value at a ~$30 share price) marginally increase insider exposure but represent <0.1 % of Ryerson’s 34 m basic shares. Because the units vest over 2026-2028, they have no short-term liquidity impact and signal no market view by the insider. From a governance lens, the filing is routine and expected under the company’s dividend-equivalent policy. Investors should treat the disclosure as neutral; it neither signals buying conviction nor selling pressure.
