The filer reports no securities sold in the past three months. Several issuer and filer contact fields are blank in the provided content and the filer did not state a relationship to the issuer in the portions shown.

Positive

• Sale details are explicit: class, broker, number of shares, aggregate value, sale date, and exchange are provided
• Acquisition origin disclosed: shares were acquired via restricted stock vesting and listed as compensation
• No recent sales: filer reports no securities sold in the past three months, simplifying aggregation calculations

Negative

• Missing filer/issuer contact and relationship fields in the provided excerpt, limiting context about the seller's status
• Amount disclosed is small relative to total outstanding shares (4,622 vs 121,094,958), which may limit materiality but prevents deeper analysis from this filing alone

Insights

Securities Analyst

TL;DR: Routine Rule 144 notice for an insider sale of 4,622 shares via a broker; disclosure appears complete for sale details but issuer/filer contact fields are missing in the excerpt.

The Form 144 discloses a proposed disposition of 4,622 common shares valued at $139,193.38 to be sold on NASDAQ through Fidelity Brokerage Services. Acquisition dates and nature are specified as restricted stock vesting with compensation as the payment source, which supports Rule 144 eligibility criteria disclosures. The filing also states no sales in the prior three months and reports the total shares outstanding. The excerpt omits certain filer and issuer contact and relationship fields, which limits assessment of the filer’s exact status (e.g., officer, director, affiliate) based solely on this text.

Corporate Governance Expert

TL;DR: This is a standard insider notice; transaction details are clear but missing contextual issuer/filer relationship information in the provided excerpt.

The notice details the mechanics of the planned sale and ties the shares to restricted stock vesting events in 2023 and 2024, indicating compensation-related issuance. The use of a registered broker and the statement that no recent sales occurred are consistent with routine compliance with disclosure obligations. Absent explicit statement of the filer’s relationship to the issuer in the provided content, one cannot determine any governance implications from this excerpt alone.
