DIRTT Releases Investor Deck Detailing its Momentum of Change

• Refreshed, highly qualified and strategically selected Board has repositioned DIRTT to improve its financial performance, enhance shareholder value and deliver future growth; a wholesale change could create significant risk.

• Warns shareholders that 22NW has put forward an underqualified slate and has not articulated a plan for the Company.

• DIRTT remains committed to working with all shareholders, including 22NW, to efficiently resolve this expensive and time-consuming proxy fight, and is prepared to consider expanding the Board to eight members and include Mr. English and another 22NW nominee.

• The deck is available on SEDAR and DIRTTmomentum.com. For help voting, please contact Kingsdale Advisors at 1-866-851-2743 or contactus@kingsdaleadvisors.com.
