Rhea-AI Sentiment reads the wording of the document, how positive or negative its language is on a 1 to 5 scale. The balance of points shown with the takes weighs what the document actually discloses, so the two can disagree, for example when a trial that missed its main goal is described in upbeat language.
Phio Pharmaceuticals Corp. received an updated ownership report from Intracoastal Capital LLC and its principals Mitchell P. Kopin and Daniel B. Asher. As of December 31, 2025, they may be deemed to beneficially own 1,142,556 shares of common stock through a warrant held by Intracoastal.
The filing states this represents approximately 9.1% of Phio’s common stock, calculated using 11,447,952 shares outstanding as of December 4, 2025 plus the warrant shares. Additional warrants for 149,298 and 759,298 shares are subject to 4.99% beneficial ownership blocker provisions and are excluded from this percentage.
Without these blocker provisions, the reporting persons may be deemed to beneficially own 2,051,152 shares. They certify the securities were not acquired to change or influence control of Phio Pharmaceuticals, and that the information is true, complete, and correct.

What ownership stake in Phio Pharmaceuticals (PHIO) is reported in this Schedule 13G/A?
The reporting persons disclose beneficial ownership of 1,142,556 Phio common shares, or about 9.1% of the class. This percentage is based on 11,447,952 shares outstanding plus the warrant shares underlying Intracoastal Capital LLC’s position.
Who are the reporting persons in the Phio Pharmaceuticals (PHIO) Schedule 13G/A?
The filing is made on behalf of Mitchell P. Kopin, Daniel B. Asher, and Intracoastal Capital LLC. Kopin and Asher are U.S. individuals, while Intracoastal is a Delaware limited liability company reporting shared voting and dispositive power over the same warrant-held shares.
How is the 9.1% beneficial ownership in Phio (PHIO) calculated in this filing?
The 9.1% is based on 11,447,952 Phio common shares outstanding as of December 4, 2025, plus 1,142,556 shares issuable upon exercise of a warrant. Only these warrant shares, labeled Intracoastal Warrant 1, are included in the ownership calculation.

Intracoastal reports a warrant, Intracoastal Warrant 1, for 1,142,556 shares included in beneficial ownership. Two additional warrants, for 149,298 and 759,298 shares, are excluded from ownership calculations due to 4.99% beneficial ownership blocker provisions in those instruments.
What are the 4.99% blocker provisions mentioned in the Phio (PHIO) Schedule 13G/A?
The filing explains that two Intracoastal warrants cannot be exercised if doing so would push the holder’s beneficial ownership above 4.99% of Phio’s common stock. Because of these blockers, 149,298 and 759,298 potential shares are excluded from the reported 9.1% stake.
Does the Phio Pharmaceuticals (PHIO) Schedule 13G/A indicate an attempt to influence control?
The reporting persons certify the securities were not acquired and are not held to change or influence control of Phio Pharmaceuticals. They also state the holdings are not part of any transaction undertaken with that control-related purpose or effect, aside from limited nomination-related activities.
