The SEC XML stores every transaction. Raspberry keeps that evidence, reads the footnotes and separates voluntary open-market activity from vesting, option exercises, gifts, tax withholding, stock purchase and dividend reinvestment plans and pre-programmed 10b5-1 trades.
The transaction reported on this Form 4 reflects an open market purchase made by the reporting person. Includes: (i) the following restricted stock units ("RSUs") that will be settled into shares of Common Stock upon vesting upon a "Change In Control" of the Company as defined in the Amended and Restated CytoSorbents Corporation 2014 Long-Term Incentive Plan (the "Plan"): (a) 10,300 RSUs granted on March 15, 2018, (b) 18,700 RSUs granted on February 24, 2017, (c) 57,000 RSUs granted on June 7, 2016 and (d) 130,000 RSUs granted on April 8, 2015; (continued from footnote 2) (iii) the following RSUs, which vest in equal parts on the first year anniversary of the date of grant and the second year anniversary of the date of grant, subject to the Reporting Person's continued service as of the applicable vesting date, and will settle into shares of Common Stock of the Company upon vesting: 96,000 RSUs granted on April 2, 2024 and of which 48,000 remain unvested as of the date hereof; (continued from footnote 3) (iv) 105,600 RSUs which shall vest in equal parts at the first and second year anniversaries of the date of grant, subject to the reporting person's continued service as of the applicable vesting date, and (v) 1,113,363 shares of Common Stock owned by the Reporting Person.
Voluntary purchases and sales; administrative noise stays hidden.
