Khan Fareeha 4

What Happened
Khan Fareeha, Chief Financial Officer of DIRTT Environmental Solutions Ltd (DRTTF), had 25,000 restricted stock units (RSUs) vest and convert into common shares on June 8, 2026. Of the 25,000 shares issued, 12,586 shares were withheld to cover tax withholding (code F) at an effective price of US$0.52 per share, totaling US$6,545. The net shares retained by Fareeha from this vesting were 12,414. The conversion is reported as an exercise/conversion of a derivative (code M) because RSUs converted into ordinary shares.

Key Details

• Transaction date: June 8, 2026 (reported on Form 4 filed June 10, 2026) — filing appears timely (within the usual two-business-day window).
• Primary transactions: conversion/exercise of derivative (M) — 25,000 shares acquired via RSU vesting; tax withholding (F) — 12,586 shares disposed at US$0.52/share for US$6,545.
• Net shares received from this vesting: 12,414 shares.
• Footnote: These RSUs were part of a 75,000 RSU grant on June 7, 2023 vesting in three equal annual installments; one-third vested on June 8, 2026 and were converted one-for-one into common shares at the issuer’s discretion. The US$0.52 per-share figure derives from the TSX closing price C$0.72 on June 8, 2026 converted to USD (Bank of Canada rate C$1.3947 = US$1.00).
• Transaction codes explained: M = exercise/conversion of derivative (RSU conversion); F = shares withheld to satisfy tax withholding.

Context
This was a routine equity compensation vesting event (not an open-market purchase or discretionary sale). The withholding of shares to cover taxes (a cashless withholding) is common on RSU vesting and does not by itself indicate a buy or sell decision by the insider.
