DIRTT Comments on Unnecessary Activist Action and Failure to Comply with Applicable Regulations

DIRTT Environmental Solutions Ltd. (“DIRTT”, the “Company”, “we” or “us”) (Nasdaq: DRTT, TSX: DRT), an interior construction company that uses proprietary software to design, manufacture and install fully customizable environments, today provided an update regarding the requisition (the “Requisition”) made by an activist investor, 22NW Fund, LP, (“22NW” or the “Activist”), and reiterates that notwithstanding its concerns regarding the Activist’s conduct, the committee of its independent directors (the “Special Committee”) tasked with reviewing and considering the Requisition remains committed to engaging in discussions with the Activist regarding this unnecessary proxy fight.

22NW’s Failure to Comply with Applicable Regulations

On December 23, 2021, the Activist filed with the U.S. Securities and Exchange Commission (the “SEC”) a preliminary proxy statement on Schedule 14A (the “Preliminary Proxy Statement”), which contained numerous statements that the Company believes are inaccurate or misleading, including but not limited to the following:

• The Preliminary Proxy Statement asserts that, on November 12, 2021, the board of directors of the Company (the “Board”) “declined to appoint Mr. English” to the Board. On such date, two members of the Board reiterated to Mr. English that the Board would consider his candidacy in February 2022 consistent with its customary review and selection process for director nominees for election at an annual general meeting, and such directors offered to send to Mr. English a form of standstill agreement that they believed would be required by the Company in connection with any appointment of Mr. English to the Board.

• The Preliminary Proxy Statement asserts that, on October 11, 2021, Mr. English participated in a telephone call with the Board Chair to “reiterate his concerns about the Company’s governance”. 22NW’s statement that the telephone call was to reiterate Mr. English’s “concerns about the Company’s governance” is misleading and fails to disclose that Mr. English’s sole concern on the call was his potential appointment to the Board.

• The Preliminary Proxy Statement asserts that, on March 8, 2021, representatives of 22NW participated in a “Cost of Ownership” tool demonstration and had been invited with other DIRTT shareholders to also participate in the demonstration. 22NW’s statement that “other DIRTT shareholders” were invited “to also participate in the demonstration” is false. The statement fails to note that 22NW and the Company agreed to invite exactly one other DIRTT shareholder, which is materially different than the statement that “other DIRTT shareholders” were invited to participate. Furthermore, such shareholder is the subject of a complaint submitted by the Company to the Alberta Securities Commission, which complaint alleges that such shareholder is acting jointly or in concert with 22NW.

• The Preliminary Proxy Statement also discloses the trading activity in DIRTT stock by the Activist, Mr. English and certain employees of the Activist during the past two years. These trades raise significant concerns regarding whether 22NW has complied with various disclosure and reporting obligations under Canadian and US securities laws. The Company has raised these issues with the Alberta Securities Commission, including apparent breaches by 22NW of certain provisions under the alternative monthly reporting regime of Canadian securities laws. The Company has shared these concerns with the Activist.

These most recent regulatory concerns are in addition to those previously identified, including that the Company shareholders have not been provided with full and fair disclosure concerning relationships amongst the Activist and certain other shareholders, their coordinated trading activities, their joint plans, and the extent of their influence and control.

The Board is raising concerns about the Activist’s activities and disclosures because they raise fundamental issues with respect to the protection of DIRTT’s minority shareholders and the equal treatment of our shareholders, and in order to ensure that shareholders have accurate and complete information to make informed decisions.

Activist’s Boilerplate Reasons for its Requisition Do Not Establish a Case for Change

The Preliminary Proxy Statement discloses some boilerplate reasons for the Requisition commonly stated in most proxy fights, but does not reflect a clear vision or plan for the Company. The Board continues to oversee management in the execution of the strategic plan for the Company, based on three key pillars: commercial execution, manufacturing excellence and innovation with a focus on improving results, and is committed to engaging with all stakeholders as it moves forward with a plan to address these concerns.

Despite the unnecessary distraction that 22NW’s Requisition has caused, the Board remains focused on the business of the Company as its priority.

Commitment to Engaging with Shareholders in an Appropriate Forum

As previously disclosed, the Company has advised the Activist that it remains committed to negotiations that benefit ALL shareholders, but will only resume such negotiations in good faith and not through press releases. Accordingly, counsel to the Company once again informed counsel to the Activist this morning that the Special Committee is prepared to have discussions with the Activist on a without prejudice basis.
