Sidus Space, Inc. received an updated beneficial ownership report from CVI Investments, Inc. and Heights Capital Management, Inc. The Reporting Persons disclose beneficial ownership of 214,935 shares of Sidus Space Class A common stock, representing about 0.3% of the class, through warrants.
The warrants are subject to a 4.99% beneficial ownership limitation, which prevents exercise if it would push the holder’s ownership above that threshold. Heights Capital Management acts as investment manager to CVI Investments and may be deemed a beneficial owner but both parties disclaim beneficial ownership beyond their pecuniary interest.
The Reporting Persons certify that the securities were not acquired and are not held for the purpose of changing or influencing control of Sidus Space.

* Previously filed
What stake in Sidus Space (SIDU) do CVI Investments and Heights Capital report?
They report beneficial ownership of 214,935 Sidus Space Class A shares, or about 0.3% of the class. This position is held through warrants rather than directly owned stock, according to the Schedule 13G/A amendment.
How are CVI Investments and Heights Capital related in the Sidus Space (SIDU) filing?
Heights Capital Management, Inc. is the investment manager to CVI Investments, Inc. and may exercise voting and dispositive power over the 214,935 shares reported. Both entities are listed as Reporting Persons in the Sidus Space Schedule 13G/A amendment.
What is the 4.99% ownership limitation mentioned for Sidus Space (SIDU)?
The reported Sidus Space shares come from warrants that are not exercisable if exercise would cause a holder’s beneficial ownership to exceed 4.99%. This cap limits how many shares can be acquired under the warrants at any one time.
Are CVI Investments and Heights Capital seeking control of Sidus Space (SIDU)?
They state the Sidus Space securities were not acquired and are not held to change or influence control of the issuer. The certification specifies the holdings are not part of any transaction with that purpose or effect.
How many Sidus Space (SIDU) shares were outstanding for this ownership calculation?
The amendment cites a Sidus Space prospectus supplement indicating 65,178,283 Class A shares were outstanding upon completion of an offering. The 0.3% ownership figure for the Reporting Persons is calculated against that outstanding share number.
Do CVI Investments and Heights Capital fully acknowledge beneficial ownership of Sidus Space (SIDU) shares?
They note Heights Capital may be deemed beneficial owner of shares owned by CVI Investments but each Reporting Person disclaims beneficial ownership of any such shares, except for its pecuniary interest, as stated in the ownership section.
