The schedule states 4,839,225 shares are held by funds and accounts under Nantahala's control as of March 31, 2026, and that 3,157,895 shares are exercisable within sixty days via convertible securities. The filing attributes shared voting and dispositive power to Nantahala and to Messrs. Harkey and Mack as managing members.

Cash‑flow treatment and any planned dispositions are not described in the excerpt; subsequent filings would state transactions if they occur. Watch later public filings for changes to the reported stake or for Schedule 13D amendments if activist intent arises.

Regulatory/Compliance Specialist

Disclosure aligns with adviser/control person reporting conventions.

The filing is an amended Schedule 13G/A identifying Nantahala as an investment adviser and Messrs. Harkey and Mack as control persons, and it attaches signatures including a Chief Compliance Officer. The statement that shares include convertible securities exercisable within sixty days is a standard beneficial‑ownership qualifier.

Confirmatory items to monitor in future filings include any change from passive 13G status to active 13D status or public trading by the reporting funds. Regulatory follow‑ups would appear in subsequent SEC schedules.

Key Terms

3 terms

beneficial owner regulatory

"Nantahala may be deemed to be the beneficial owner of 4,839,225 Shares"

A beneficial owner is the person who ultimately owns or controls a financial asset or property, even if their name isn't directly on official documents. Think of it like someone who secretly holds the keys to a safe deposit box—others may appear to have access, but the true owner is the one who benefits from what's inside. Identifying beneficial owners helps ensure transparency and prevent illegal activities like money laundering or fraud.

convertible securities financial

"Include 3,157,895 Shares which may be acquired by the Reporting Persons within sixty days through the exercise of convertible securities"

Convertible securities are bonds or preferred shares that can be exchanged for a company’s common stock at a predetermined price or under specified conditions. They matter because they combine the steadiness of a loan or fixed dividend with the potential upside of ownership; like a safety‑net that carries a one‑time ticket to become a shareholder, they affect expected returns and can dilute existing stock if converted.

Schedule 13G/A regulatory

"This as a control person in respect of shares beneficially owned by Nantahala"

A Schedule 13G/A is an amended public filing with the U.S. securities regulator that updates a previous Schedule 13G, disclosing when an individual or group holds a substantial (typically over 5%) stake in a company and is claiming a passive, non‑controlling intent. Investors monitor these updates because rising or falling holdings can signal changing confidence, potential future moves, or shifts in voting power — like watching a public ledger where large shareholders quietly adjust their positions.
