DIRTT Announces Adoption of Shareholder Rights Plan

CALGARY, Alberta, December 7, 2021 (GLOBE NEWSWIRE) — 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 announced that its board of directors (the “Board”) has approved the adoption of a shareholder rights plan (the “Rights Plan”) pursuant to a shareholder rights plan agreement entered into with Computershare Trust Company of Canada, as Rights Agent, dated December 7, 2021 (the “Effective Date”).

Shareholder Rights Plan

The Rights Plan has been adopted to help ensure that all shareholders of the Company are treated fairly and equally in connection with any unsolicited take-over bid or other acquisition of control of DIRTT (including by way of a “creeping” take-over bid). The Rights Plan is consistent with the shareholder rights plan that the Company had in place from 2014 to 2020 and is similar to shareholder rights plans adopted by other Canadian public companies.

The Rights Plan is not being adopted in response to any specific proposal to acquire control of the Company, and the Board is not aware of any pending or threatened take-over bid for the Company. However, the Board is aware that 22NW Fund, LP (“22NW”) has announced that it intends to seek to replace six members of the Board. The Rights Plan allows 22NW to proceed with their nominations and solicit proxies in respect of the Company’s next annual general and special meeting of shareholders, which is scheduled to be held on April 26, 2022 (the “Meeting”).

At the close of business on December 17, 2021 (the “Record Time”), one right (a “Right”) will be issued and attached to each common share of DIRTT outstanding at that time. A Right will also be attached to each common share issued after the Record Time. The issuance of the Rights will not change the manner in which shareholders trade their common shares. Subject to the terms of the Rights Plan, the Rights issued under the Rights Plan become exercisable only if a person (the “Acquiring Person”), together with certain related persons (including persons “acting jointly or in concert” as defined in the Rights Plan), acquires or announces its intention to acquire 20% or more of the common shares without complying with the “Permitted Bid” provisions of the Rights Plan. The Rights Plan will not be triggered solely by the holding of 20% or more of the Company’s common shares by a shareholder and its affiliates, associates and joint actors prior to the date hereof, as any such person would be “grandfathered” subject to the terms of the Rights Plan; however, subsequent purchases of common shares of the Company by a “grandfathered” person after the Effective Date may cause such person to become an Acquiring Person pursuant to the terms of the Rights Plan. Following a transaction that results in a person becoming an Acquiring Person, the Rights entitle the holder thereof (other than the Acquiring Person and certain related persons) to purchase common shares at a significant discount to the market price at that time.

Under the Rights Plan, a “Permitted Bid” is a take-over bid made in compliance with the Canadian take-over bid regime. Specifically, a Permitted Bid is a take-over bid that is made to all shareholders, that is open for 105 days (or such shorter period as is permitted under the Canadian take-over bid regime) and that contains certain conditions, including that no common shares will be taken up and paid for unless more than 50% of the common shares that are held by independent shareholders are tendered to the take-over bid.

While the Rights Plan is effective as of the Effective Date, it is subject to shareholder ratification within six months of its adoption. The Board intends to recommend the ratification of the Rights Plan for approval by its shareholders at the Meeting. If ratified by shareholders, the Rights Plan will have an initial term of three years. If the Rights Plan is not ratified by the Company’s shareholders at the Meeting, the Rights Plan and all Rights issued thereunder will terminate and cease to be effective at that time.

The Toronto Stock Exchange (the “TSX”) has notified the Company that it will defer its consideration of the acceptance of the Rights Plan until such time as it is satisfied that the appropriate securities commission will not intervene pursuant to National Policy 62-202. However, as noted earlier, the Board is not aware of any pending or threatened take-over bid for the Company. A deferral of acceptance of the Rights Plan by the TSX does not affect the adoption or operation of the Rights Plan, which will remain operative and effective for a minimum of six months from the Effective Date, unless shareholder ratification is not obtained at the Meeting or earlier terminated.

The description of the Rights Plan in this press release is qualified in its entirety by the full text of the Rights Plan, which will be available under the Company’s profile on SEDAR at www.sedar.com or at www.sec.gov.
