Positive

• Clear disclosure of aggregate beneficial ownership equal to 4,607,957 Class A shares (9.99% when includable conversions are considered).
• Identification of holdings by entity (5,044,866 Class B with GCP II; 2,061,643 Class A and 130,631 Class B with GCG III) provides transparency.
• Conversion Restriction is disclosed, showing contractual limits that prevent conversion-based ownership from exceeding 9.99%.

Negative

• No sole voting or dispositive power reported for the filing entities, indicating control is shared rather than held outright.
• Ownership concentrated near the 9.99% threshold, which triggers contractual limits on conversions and may constrain future changes in economic or voting exposure.

Insights

Securities Analyst

TL;DR: Greycroft holds a near-10% economic stake in MNTN with shared voting power and a contractual conversion cap.

The Schedule 13G shows the reporting persons collectively beneficially own 9.99% of Class A common stock when includable convertible Class B shares are considered. Ownership is allocated between GCP II and GCG III, with shared voting and dispositive authority and no sole control recorded. The filing highlights a contractual "Conversion Restriction" that prevents conversions that would push ownership above 9.99%, which directly determines reported Class A exposure. This is a routine passive investor disclosure under Schedule 13G with materiality driven by the near-10% threshold for class ownership.

Corporate Governance Expert

TL;DR: Shared control and a conversion cap shape Greycroft's influence despite sizable economic ownership.

The document clarifies that governance influence is exercised via shared voting power through general partner entities, not sole authority. The reporting persons explicitly disclaim group status. The Conversion Restriction is a key contractual limit affecting potential voting dilution from conversions. Signatures by the managing partner validate the filing. The disclosure is complete for Schedule 13G purposes and signals passive investor status rather than active control.
