Sucharczuk Guy 4

What Happened

• Guy Sucharczuk, Senior Vice President and President of Aurora Networks at Vistance Networks (VISN), was awarded 2,184 performance share units (PSUs) on 02/24/2026. The reported acquisition price is $0.00 (this is an equity award, not a cash purchase). These additional PSUs were determined to be earned based on actual performance and are scheduled to vest on 06/01/2026, subject to his continued employment.

Key Details

• Transaction date and price: 02/24/2026; award recorded at $0.00 per share (code A — grant/award).
• Vesting: The 2,184 PSUs will vest on 06/01/2026, contingent on continued employment.
• Related prior determinations: On 01/08/2026, the Compensation Committee determined 12,243 PSUs were earned; earlier, portions of PSUs representing 50,800 shares were approved to vest effective 12/18/2025 based on estimated performance (see footnote F1).
• Unvested awards on record (per filing footnote F2) include multiple RSU grants (52,800; 107,200; 94,500) and 83,718 PSUs earned 01/08/2026 — all subject to continued employment and various staggered vesting dates through 06/01/2028.
• Shares owned after the reported transaction are not specified in the excerpt. The Form 4 was filed 02/26/2026 for a 02/24/2026 transaction and appears timely (Form 4 is generally due within two business days).

Context

• These are performance-based equity awards (PSUs/RSUs), common components of executive compensation. They are not purchases or sales — value is realized only if and when the awards vest and the shares are sold. Such awards signal compensation alignment with company performance but do not directly indicate open-market buying or selling by the insider.
