Rhea-AI Filing Summary

iSpecimen Inc. filed an amended current report to update the terms of its Series C Convertible Non-Voting Preferred Stock. On January 16, 2026, the company filed an Amended Certificate of Designation that modifies Section 7 of the original designation. The change makes both the Conversion Price and the Floor Price subject to proportionate adjustment if there is any reverse stock split, share combination or similar transaction that reduces the number of outstanding common shares.

Insights

Capital structure specialist

iSpecimen realigns Series C preferred conversion math with future reverse splits.

The amendment clarifies how the Series C Convertible Non-Voting Preferred Stock will behave if iSpecimen completes a reverse stock split or similar share consolidation. By tying both the Conversion Price and the Floor Price to proportionate adjustment when the common share count decreases, the terms help preserve the economic relationship between preferred and common shares through such capital structure changes.

This adjustment was approved by the company and holders of more than a majority of the Series C Preferred Stock under the process allowed in the original certificate. The filing also confirms that, aside from these conversion-related mechanics, all other terms and preferences of the Series C Preferred Stock stay in effect, so the impact is focused on how any future structural share changes flow through to preferred conversions.
