[SCHEDULE 13G] SYNCHRONOSS TECHNOLOGIES INC SEC Filing

Rhea-AI Filing Summary

Mount Logan Capital Inc. filed a Schedule 13G reporting ownership linked to 180 Degree Capital's recent business combination that closed on September 12, 2025. The filing states the reporting person holds an aggregate position of approximately 7.5% of Synchronoss Technologies (CUSIP 87157B400). The filing records shared voting and dispositive power over the reported shares and notes that certain securities assigned to 180 Degree Capital (restricted shares and options originally held by Kevin M. Rendino) remain unvested and therefore are excluded from the aggregate amount. The statement also indicates former 180 Degree Capital executives no longer exercise voting or dispositive authority over the reported shares.

Positive

• Reported 7.5% ownership of Synchronoss Technologies, a clearly disclosed, material minority stake
• Acquisition via an all-stock business combination with 180 Degree Capital is transparently disclosed
• Certification that the position was not acquired to influence control (Schedule 13G filing)

Negative

• Inconsistency in share counts appears in the filing (867,899 in one table vs. 866,788 in Item 4), which could cause confusion
• Certain assigned securities are unvested and excluded from the reported aggregate, meaning full economic exposure is not reflected

Insights

Financial Analyst

TL;DR: Mount Logan reports a meaningful 7.5% stake tied to a recent business combination, with shared control over the position.

The filing shows Mount Logan Capital acquired its position via an all-stock business combination with 180 Degree Capital that closed on September 12, 2025. The reporting person discloses shared voting and dispositive power over the stake and quantifies the holding as representing 7.5% of the class. This is a non-active Schedule 13G filing, certified to indicate the position was not acquired to influence control. The disclosure of assigned restricted shares and options that remain unvested is material for calculating fully diluted influence but the filing includes only vested/owned shares in the aggregate reported amount.

Corporate Governance Expert

TL;DR: Governance impact appears limited—shared control reported and former executives no longer control the shares.

The schedule emphasizes that voting and dispositive authority over the reported shares is shared, and that former 180 Degree Capital officers (Kevin Rendino and Daniel Wolfe) no longer retain voting or dispositive authority for these shares. The filing also references Assignment and Assumption Agreements transferring control to 180 Degree Capital (now Mount Logan), and notes certain assigned securities remain unvested and excluded from the reported aggregate. These factors suggest the reported stake does not currently represent unilateral control of Synchronoss.

Comment for Type of Reporting Person: The foregoing shares of Common Stock were acquired by 180 Degree Capital Corp. ("180 Degree Capital"), which merged with the Reporting Person in an all-stock transaction that closed on September 12, 2025 (the "Business Combination"). There were no shares owned or acquired by the Reporting Person separate from the shares owned by 180 Degree Capital prior to the Business Combination. Prior to the Business Combination, 180 Degree Capital entered into Assignment and Assumption Agreements (the "Assignment Agreements") for restricted shares of Common Stock of the Issuer and options for the purchase of Common Stock of the Issuer received by Kevin M. Rendino, the former Chief Executive Officer of 180 Degree Capital, that Mr. Rendino received as compensation as a member of the Board of Directors of the Issuer. The Assignment Agreements attached hereto as Exhibits 99.2 and 99.3 assign all economic, voting and dispositive control of such securities of the Issuer to 180 Degree Capital, which assignment has transferred to the Reporting Person with the close of the Business Combination. The securities of the Issuer covered by the Assignment Agreements that are not included in Row 9 are unvested as of the date of this Schedule 13G. Subsequent to the completion of the Business Combination, Mr. Rendino and Daniel B. Wolfe, the former President and Chief Financial Officer of 180 Degree Capital no longer have voting or dispositive authority of the shares reported in this Schedule 13G, and therefore their personal holdings of the Issuer are not reported on this Schedule 13G. Neither of Messr. Rendino or Wolfe own more than 5% of the Issuer individually.
