-

Analysis · CLGN · Industrial Applications And Services
The Loewenbaum family group has removed Nachum Shamir, Patrick Chalmers, and Reginald J. Hargrove from its reporting group, reducing its aggregate beneficial ownership from 33.0% to 24.99%. This is a material change in the group's composition and stake, though the group remains the largest shareholder. Separately, the Loewenbaum 1992 Trust transferred funds to the company for the Series B warrant exercise price but has not exercised the warrants, leaving the funds in abeyance. This suggests the group is positioning to maintain its stake below the 24.99% beneficial ownership limitation while retaining the ability to exercise warrants later.
