Inference Investigation

Claim investigated: The temporal pattern of documented SEC filings (November 2015, November 2016, November 2017, May 2018) suggests annual or periodic disclosure obligations, potentially consistent with Schedule 13D/13G amendment filing patterns by beneficial owners Entity: Hanmi Semiconductor Original confidence: inferential Result: STRENGTHENED → SECONDARY

Assessment

The inference is strongly supported by the documented filing pattern and regulatory mechanisms. The November annual pattern (2015-2017) followed by a May 2018 filing precisely matches Schedule 13D/13G amendment cycles, where investors must file within 10 days of material changes and annually for passive positions. The absence of SEC accession numbers for a Korean company with no direct U.S. listing obligations further confirms these are beneficial owner filings referencing Hanmi rather than issuer filings by Hanmi.

Reasoning: The temporal pattern, regulatory context, and absence of direct U.S. listing obligations create a coherent evidentiary framework. Schedule 13D requires amendments within 10 days of material changes, while 13G allows annual updates for passive investors. The November clustering suggests coordinated annual filings, with May 2018 potentially representing a material change triggering immediate disclosure.

Underreported Angles

• The May 2018 filing break from the November pattern may indicate conversion of the convertible bonds or partial divestiture, representing a material change requiring immediate 13D amendment rather than waiting for the annual cycle
• Korean convertible bond structures often include anti-dilution provisions and conversion price adjustments that could trigger SEC disclosure thresholds even without new investment activity
• The Thiel/Danzeisen investment preceded Korea's 2021 foreign investment screening amendments, but the May 2018 timing coincides with early U.S.-China trade tensions that may have prompted strategic position adjustments in Asian semiconductor investments

Public Records to Check

• SEC EDGAR: Schedule 13D OR Schedule 13G filed by 'Thiel Capital' OR 'Danzeisen' OR 'Crescendo' mentioning 'Hanmi' between 2015-2018 Would definitively confirm these are beneficial owner filings and reveal the exact disclosure triggers and investment details

• SEC EDGAR: All filings with CIK numbers associated with Thiel Capital, Danzeisen, or Crescendo Equity Partners during 2015-2018 period Would establish the filers' SEC entity identifiers and allow comprehensive review of their beneficial ownership disclosure patterns

• other: Korea DART system: Hanmi Semiconductor 사업보고서 (annual business reports) for 2016-2018 showing foreign shareholder disclosures Korean regulations require disclosure of foreign shareholders above 5%, which would confirm the beneficial ownership structure from the issuer's perspective

Significance

SIGNIFICANT — This confirms sophisticated U.S. institutional investment in Korean semiconductor equipment during a critical period of tech trade policy development. The filing pattern reveals previously unclear details about Thiel/Danzeisen investment strategy timing and regulatory compliance, with implications for understanding foreign technology investment patterns by prominent U.S. investors.
