Insights

Market Structure Specialist

Form 25 signals removal of OUST from Nasdaq listing; market access and liquidity will change once effective.

The filing notifies that the Exchange has submitted a Form 25 to remove a class of securities for Ouster, Inc. (OUST) from listing and/or registration. This is the formal regulatory step that begins or records the administrative process to delist securities under Section 12(b).

Key dependencies include the effective date and whether the removal is voluntary or involuntary; neither is specified here. Investors should note that delisting typically affects trading venue, liquidity, and market access once the action becomes effective, often within a short regulatory timeframe.

Corporate Governance Advisor

The Exchange affirms procedural compliance but the filing lacks specifics on rule selection and timing.

The submission states Nasdaq has complied with its rules and certifies reasonable grounds for filing. The form lists the rule citations commonly used for withdrawals or delistings but does not indicate which checkbox (if any) was marked or provide the signature/date block content.

Absent the effective date or a signed notice, material details remain missing here; stakeholders will need the accompanying Notice of Removal or subsequent filings for firm timing and the issuer's stated rationale within days to weeks.
