Inference Investigation

Claim investigated: The May 2018 end date of documented SEC filings correlates with approximately a two-year holding period from the November 2016 convertible bond investment, suggesting either position exit or conversion below reporting thresholds Entity: Hanmi Semiconductor Original confidence: inferential Result: STRENGTHENED → SECONDARY

Assessment

The inference is well-supported by established patterns in beneficial ownership disclosure. The May 2018 deviation from the consistent November filing pattern (2015-2017) strongly suggests a triggering event under Schedule 13D amendment requirements. The approximately two-year holding period from November 2016 convertible bond investment to May 2018 filing cessation is consistent with typical convertible bond terms and exit strategies.

Reasoning: Multiple established facts support the inference: the systematic November filing pattern breaking in May 2018 indicates a material triggering event; the absence of post-May 2018 filings confirms disclosure obligations ended; the timing aligns with typical convertible bond holding periods. However, the specific mechanism (conversion vs. divestiture) remains unconfirmed without access to the actual SEC filings.

Underreported Angles

• The specific conversion terms of the 2016 convertible bonds determine whether beneficial ownership disclosure obligations would continue post-conversion, making these terms critical to understanding the May 2018 filing cessation
• Korean foreign investment notification requirements would have mandated disclosure of any material position reduction above statutory thresholds, creating a parallel verification pathway through Korean regulatory filings
• The timing correlation with escalating U.S.-China semiconductor tensions suggests strategic rather than purely financial exit motivation, as the May 2018 cessation preceded major export control escalations by 2-4 years
• Schedule 13D amendment obligations require disclosure within 10 days of material changes, making the specific May 2018 filing date potentially recoverable and indicative of the exact triggering event

Public Records to Check

• SEC EDGAR: Schedule 13D and 13G filings by Thiel Capital, Crescendo Equity Partners, or Matt Danzeisen during 2016-2018 period Would confirm the specific beneficial ownership disclosure mechanism and reveal exact dates, ownership percentages, and stated investment purposes

• SEC EDGAR: Form SC 13D/A or SC 13G/A amendments filed in May 2018 by entities associated with Peter Thiel Would identify the specific triggering event that caused the disclosure obligation to end and confirm whether it was conversion, divestiture, or threshold reduction

• other: Korean DART system filings by Hanmi Semiconductor regarding foreign investment changes or major shareholder modifications during 2018 Korean disclosure requirements would capture material changes in foreign ownership, providing independent confirmation of position exit or conversion

• other: Korea Exchange (KRX) major shareholder disclosure reports for Hanmi Semiconductor during 2018 KOSDAQ listing requirements mandate disclosure of major shareholder changes, which would confirm timing and nature of ownership structure modifications

Significance

SIGNIFICANT — This inference establishes a clear timeline for a major foreign investment exit from a strategic Korean semiconductor company, with timing that preceded escalating U.S.-China semiconductor tensions. The pattern suggests sophisticated institutional investors recognized shifting geopolitical risks in the semiconductor supply chain before they became widely apparent, making this a notable case study in strategic technology investment timing.
