📊 1. [Summary of Core Disclosure Content and Major Figures]
- Subject and Date of Amendment: The disclosure initially submitted on April 22, 2025, has been formally amended as of 2025-04-30.
- Reason for Amendment: Schedule revisions aligning with updates to Hanwha Aerospace’s paid-in capital increase timeline.
- Expected Effective Date: 2025-05-22 (Thursday) *The ex-rights date of the underlying stock.
- Amended Valuation Formulas by Market Measure:

- Contract Multiplier Adjustment (Futures contracts with open interest as of May 21, 2025, and all contract months for options): Adjusted Contract Multiplier = Contract Multiplier Before Adjustment × (Closing Price of Underlying Stock on the Day Prior to Ex-Rights Date ÷ Adjusted Base Price of Underlying Stock)

📈 2. [Expert View: What This Disclosure Means for Investors]
This filing details the administrative update to the quantitative adjustment schedules slated for stock futures and options written on Hanwha Aerospace, responding to the timeline shifts of its paid-in capital increase framework. It rectifies the initial schedule from April 22, explicitly laying out the mathematical formulas for base prices, contract multipliers, and strike prices within a standardized amended regulatory table.
The quantitative variables to track are the execution dates re-anchored to the underlying asset’s ex-rights date of May 22, 2025. Because the mechanical calculation functions modifying the nominal value of each derivative contract are tied directly to the ratio between the adjusted base stock price and the closing price on the eve of ex-rights, investors should focus on verifying the separate technical metrics scheduled for publication on May 21 and check their implementation status on the effective date of May 22.
📝 Editor’s Comment (by K-STOCK Editor)
Hanwha Aerospace’s latest amended disclosure officially establishes the corrected chronological window and the corresponding mathematical parameters defining how contract specifications across its stock futures and options markets will be altered due to the modified capital raise timeline. The structural adjustments apply uniformly across all outstanding contract months for the specified derivatives.
The primary objective checkpoint for investors going forward is monitoring the subsequent publication of the detailed technical metrics and verifying timeline adherence. As explicitly dictated in the regulatory amendment, the exact numerical figures for these adjustments are scheduled for publication on May 21, 2025, making it an essential target date to check.
Additionally, as noted under the critical considerations section, the market measure framework remains subject to potential modifications depending on the continuous execution status of Hanwha Aerospace’s capital raise. Consequently, investors should independently cross-reference whether upcoming follow-up filings regarding the capital raise and the steps mandated by derivative market enforcement rules are implemented in accordance with the updated schedule.
