KOUNINIS EFSTATHIOS A

Efstathios A. Kouninis (CIK 0001353196, 1,596 transactions since December 2008) runs a bi-modal Pegasystems Inc. (PEGA) file: the dominant pattern is clustered M/F-code exercise-and-withholding events firing in March and June each year — June 7, 2026 session opened with M (332 shares), F (81 shares at $34.71), M (332 shares) then June 5: M (440 shares), F (108 at $35.44), M (440). The June 4 session opened with a larger 3-part M/F set (M 324 + F 79 + M 324 at $35.11) followed on June 16 by a small-lot S-sell (750 shares at $32.31–$32.32). The March 2026 response events carried larger M/F lots (M 332+2208+1292, F 655+313 at $45.01) and an unusual A-code pair on March 3, 2026 (1,961 + 4,469 shares at no price), suggesting a timing-vesting/RSU-award cadence concentrated near fiscal-quarter-close. Lifetime: 168,805 sell shares, zero buy-side, plus a vestigial 2006–2007 Tasker Products Corp (tker) secondary with 450,000 sell shares. Honest read: an 18-year executive whose PEGA equity is governed by a normal equity-award cycle with consistent option-exercise and tax-withholding events across multiple price bands — the $34–$47 recent range makes the F-tax events small relative to the option-value gain.
