BlackSky (BKSY): Mithril/Royan & Thiel Hold 6.6% After Dilution

Rhea-AI Filing Summary

This amendment to a Schedule 13D updates the ownership percentages for multiple Mithril-related reporting persons and individuals in BlackSky Technology, Inc. The filing reports that Mithril I holds 1,298,328 shares (3.7%) and Mithril II holds 1,030,175 shares (2.9%) of Class A Common Stock, using a share base of 35,464,515 shares outstanding as reported by the issuer. Ajay Royan and Peter Thiel are reported as beneficial owners of a combined 2,328,503 shares (6.6%).

The amendment states the change in percentage ownership resulted from dilution caused by the issuer's sales of additional shares and was not due to sales by the reporting persons; the aggregate percentage decreased by over 1%. No other items in the original Schedule 13D were amended.

Positive

• Combined beneficial ownership disclosed: Ajay Royan and Peter Thiel hold 2,328,503 shares (6.6%).
• Clarifies source of change: The amendment attributes the decline in percentage to issuer share issuance (dilution), not to dispositions by the reporting persons.

Negative

• Ownership percentage declined by over 1% due to the issuer's additional share sales, reducing the reporting persons' stake.
• Dilution reduced relative influence even though absolute share counts reported for the reporting persons did not change.

Insights

Securities Analyst

TL;DR: Amendment records dilution-driven decline in ownership percentages; share counts unchanged, resulting in a modest, non‑controlling stake.

The filing confirms that the reported share counts for Mithril I and Mithril II remain intact while their percentage ownership declined because the issuer sold additional shares. The combined beneficial ownership of 2,328,503 shares (6.6%) is material to disclosure but remains below thresholds normally associated with control proposals. The amendment provides transparency about the source of the change—issuer dilution rather than disposals by the reporting persons—which is relevant for market participants assessing insider intent or stake accumulation.

Corporate Governance Expert

TL;DR: Shared voting and dispositive arrangements are disclosed; governance influence is outlined but not materially altered by this amendment.

The disclosure reiterates that shared voting, investment and dispositive power arises from the Mithril fund structures and designated investment committees, with Ajay Royan and Peter Thiel serving on those committees. The filing clarifies the chain of record ownership and who may be deemed to exercise shared authority over the securities. This enhances clarity on who exercises influence over the reported shares, an important detail for governance assessments, though it does not indicate any change in board or control arrangements.

(c)	Address of Issuer's Principal Executive Offices: 2411 Dulles Corner Park, Suite 300, Herndon, VIRGINIA , 20171.
Item 1 Comment: This Amendment No. 3 (this "Amendment No. 3") amends and supplements the Schedule 13D originally filed by the Reporting Persons with the Commission on September 20, 2021, as it has been amended by Amendment No. 1 filed with the Commission on April 20, 2024 and Amendment No. 2 filed with the Commission on November 12, 2024 (collectively, the "Original Schedule 13D"). The agreement among the Reporting Persons to file jointly in accordance with the provisions of Rule 13d-1(k)(1) under the Act is attached to the Original Schedule 13D as Exhibit 1. This Amendment No. 3 is being filed to update the aggregate percentage of the Common Stock owned by the Reporting Persons due to dilution caused by the Issuer's sales of additional shares of its Common Stock from time to time since the date of the filing of Amendment No. 2 and not in connection with a disposition of any shares by the Reporting Persons. Such dilution resulted in a decrease of over one percent (1%) in the aggregate percentage ownership reported by the Reporting Persons in Amendment No. 2. Only those items that are hereby reported are amended; all other items reported in the Original Schedule 13D remain unchanged. Information given in response to each item shall be deemed incorporated by reference in all other items, as applicable. Capitalized terms not defined in this Amendment No. 3 have the meanings ascribed to them in the Original Schedule 13D.
