Our Solutions

We offer a wideOur ever-expanding array of interior construction solutions powered by technologyproducts and integrations give our clients the tools to create high-performing interiors that addressstay relevant into the challenges inherent in traditional interior designing and construction methods.future. Unlike traditional interior construction, including traditionalconventional prefabricated products, our solutions do not have predetermined shapes, sizes, or configurations, soempowering clients are free towith design any shape, size or configuration that is necessaryfreedom to meet their needs. Our design and visualization technologies integrate with our manufacturing capabilities and enable short and precise manufacturing times. With a strong network of Distribution Partners, we are able to complete an interior construction project in as few as 30 days, from visualization and completion of design to installation and move-in. Because our solutions remain highly adaptable over time, clients are able to change and customize our solutions even after installation to maintain satisfaction with the functionality and aesthetics of their space as their needs change.

Sustainability practices are aThe core part of our business, fromproduct philosophy is a construction system that uses a universal interface. By allowing interchangeable parts, DIRTT can maximize the life cycle for most of our products. Committed to sustainability, we subscribe to non-obsolescence, where new DIRTT components work with DIRTT products that came before. Our solutions can be disassembled and reconfigured with minimal waste. With both design freedom and manufacturingadaptability benefits, client spaces are tailored to installationtheir unique needs on Day One and can be more easily reconfigured or adapted to stay relevant on Day Two and beyond.

Our solutions are form-fit, so the only waste produced at job sites is packing material, which is biodegradable, recyclable ortypically able to be returned to DIRTT for reuse.

Walls, doors, cabinetry, access floor, ceilings, power solutions, data networks, heavy timber and medical gas componentsComponents are all fabricatedmanufactured in our manufacturingDIRTT facilities and shipped to the site for final assembly and installation. The following table provides a brief description of our primary solutions (together with related complementary offerings, “DIRTT Solutions”):solutions:

Our DIRTT Power and DIRTT Networks solutions may be integrated with DIRTT Walls, and DIRTT Networks solutions may also be integrated with DIRTT Floors and DIRTT Ceilings. DIRTT Millwork solutions may be added to DIRTT Walls for decorative and functional purposes. Additionally, DIRTT Walls, DIRTT Floors, DIRTT Ceilings and DIRTT Timber may be integrated among each solution.7

ICE^® Software

Our manufacturing approach is built on a foundation of technology, the core of which is our proprietary ICE Software. We use ICE to sell, design, visualize, configure, price, communicate, engineer, construct, specify, order and manage projects. ICE enables us to efficiently manufacture fully custom interiors while addressing challenges associated with traditional construction, including cost

overruns, inconsistent quality, delays and significant material waste. ICE also gives our clients control over the look, cost and timing of their interior construction projects.

Clients typically engage an architect or designer and initially design their interior including space planning, materials, colors, finishes, which are then often presented in two-dimensional renderings or a building information model (“BIM”). A Distribution Partner imports this design into ICE and prices projects in real time. Clients can make changes after the design is imported into ICE, which will immediately be reflected in the price quote. Throughout these iterations, clients can explore and walk through their proposed space in immersive and interactive 3D virtual reality, on-screen computer renderings, and floorplan details so they can more readily understand the design. Throughout every stage of the process design changes can be made easily and in real time. We believe this is a significantly enhanced experience for our clients as compared with the experience of reviewing a two-dimensional blueprint or CAD drawing or user expertise intensive BIM file. In addition to our core product offering, DIRTT enables integrations with technology, custom graphics, writable surfaces, and Breathe® Living Walls. Further product information can be found on dirtt.com.

Sustainability and Environmental Matters

DIRTT aims to minimize the ICE toolsenvironmental impact of interior construction through careful material selection, efficient operations, a system designed for future adaptability, and long product lifecycles. We work with clients to understand their unique sustainability goals and identify how building with DIRTT can support LEED, WELL, Living Building Challenge, and other green building standards they may be targeting. Our sustainability team helps to calculate various elements of the DIRTT scope that enable these experiences at eachsupport certification.

Approximately 40% of solid waste in the United States derives from construction and demolition. In contrast, DIRTT’s agile construction system makes it quick, easy, and cost effective to evolve interior spaces through future reconfigurations and relocations, while minimizing waste. Our agile system is designed for disassembly to reduce the carbon footprint of new construction and future changes. We further reduce waste through efficient manufacturing and pre-assembled solutions.

We continuously evaluate the environmental impact of our Distribution Partners,materials, considering impact on the wellness of the occupants using the spaces we currently have four specialized virtual reality walk-through centers, including one at our corporate headquarters, that allow clientsbuild and life cycles of the products we make. DIRTT endeavors to use virtual reality headsetsmaterials with high recycled content, bio-based content, and low or no volatile organic compounds (VOCs). Most DIRTT assemblies are certified through Science Certification Systems (SCS) Indoor Advantage Gold, recognizing their low-emitting properties. DIRTT wall panel and casework facilities are certified to physically walkhandle materials with FSC® certification (FSC-C006900), ensuring FSC certified products may be specified.

We recognize the vital importance of reducing embodied carbon within DIRTT products. Our environmentally conscious production facilities are continuously evaluated by cross-functional teams who assess and implement energy efficiency strategies. For example, to further reduce our operational carbon footprint, DIRTT’s US factories are powered by renewable energy through a 3D virtual reality modelour purchase of their design. ICE’s virtual and augmented reality technology, including applications for phones, tablets and PCs, allows project stakeholders in different physical locations to meet in real time to visualize, move about, interact with, discuss and edit their future spaces without having to visit oneGreen-e® certified renewable energy credits (RECs). We further reduce the impact of our virtual reality walk-through centers. ICEoperations with recycling and waste diversion programs.

DIRTT releases an annual Environmental, Social, and Governance (ESG) report outlining our commitments to sustainability and the environment. It also provides the abilitydisclosure of our current environmental and sustainability impacts. By 2025, DIRTT has committed to export a BIM file for use in design reviewsreducing our landfill waste from 2021 levels by 35% and sourcing or producing renewable energy to cover 100% of an entire project consisting of non-DIRTT construction elements coming from many different types of software.our factory operations.

Once the client is satisfied with the design in ICE, the specifications are transmitted to our manufacturing facilities, where the physical product solutions are created to the exact design standards and specifications set forth in the design. ICE’s detailed bill of material data output is key to managing the many aspects of the manufacturing process, including product inventory and cataloguing, price quotation, order submission, parts manufacturing, and production management, thereby facilitating the delivery of custom solutions with shorter production times. We allocate production among our manufacturing facilities based on proximity to the job site and available capacity. ICE’sFurther information allows a project to be tracked in detail across the entire life of the project, from sales, production, delivery, and installation. The ICE file (containing a project’s engineering and manufacturing data) generated during the design and specification process is preserved andabout DIRTT’s sustainability practices can be used for optimizing future reconfigurations, renovations, technology integration initiatives and changes to a client’s spacefound at lower cost than traditional construction methods.dirtt.com/sustainability.

Our Business Strategy

Our goal is to help clients envision and design interior construction projects and then build and deliver those projects faster, cleaner, more efficiently and with a better overall client experience and satisfaction than traditionalconventional construction methods. The modular aspect of our DIRTT Solutionsconstruction system allows them to be easily reconfigured with a minimal amount of waste as client space needs change. Our innovative, technology-driven approach includes outstanding product design that is customized for each client application and delivered on time and on budget.

Our strategy is founded on the following priorities:

In combination with a focus on cost-discipline, a continuous improvement philosophy, and a focused approach to capital investment, we believe these strategic priorities will drive increased value creation for our employees, clients, DistributionConstruction Partners, and shareholders.

Our Competitive Strengths

We believe the following attributes provide us with competitive strengths in the interior solutions manufacturingindustrialized construction industry:

DistributionConstruction Partners and Sales Network

We primarily sell DIRTT Solutions through a network of independent DistributionDIRTT Construction Partners working in conjunction with local DIRTT sales representatives, as well as internal DIRTT industry specialists, business development professionals and a dedicated DistributionConstruction Partner support team. DistributionConstruction Partners and local sales representatives are located in cities throughout the United States and Canada, as well aswith additional locations in select international markets.Singapore and the United Kingdom. The use of a dispersed network of DistributionConstruction Partners greatly enhances our ability to drive awareness of the DIRTT brand and understanding of our approach to construction throughout our markets.

9

As part of our distribution agreements, our 72 DistributionConstruction Partners are typically required to invest in their own DIRTT Experience Center (“DXC”) so that they are able to effectively showcase DIRTT Solutions. These DXCs are showrooms that provide

mock-ups of DIRTT Solutions and related product offerings. As well, DIRTT maintains DXCs in Calgary, Toronto, Chicago, New York City, Savannah, Phoenix, Salt Lake City, with an additional DXC under construction inand Dallas.

Our DistributionConstruction Partners operate under agreements that outline sales goals and marketing territories which are generally non-exclusive. We expect our DistributionConstruction Partners to build regional DIRTT-dedicated teams (sales, design and project management) and to use our ICE Software in the sales process. In addition to sales and marketing, our DistributionConstruction Partners provide value throughout the construction process. At the pre-construction stage, DistributionConstruction Partners provide design assistance services to the architect and designer; throughout the construction process, DistributionConstruction Partners act as a specialty subcontractor to the general contractor and provide installation and other construction services. Post-move in, DistributionConstruction Partners provide warranty work, ongoing maintenance and reconfiguring support. Local DIRTT sales representatives work closely with the DistributionConstruction Partners throughout the process to ensure successful project implementation and the highest client satisfaction. DistributionConstruction Partners generally place orders for DIRTT Solutions directly with us and pay us directly for such orders.

We have the ability to bring on new DistributionConstruction Partners in a wide range of geographic areas, which permits us to quickly establish a presence in new market areas. Our DistributionConstruction Partners also scale our virtual reality technology, such as our smart phone- and tablet-based applications, to fit their capacity and needs.

At December 31, 2020,2022, we had a total of 72 Distribution67 Construction Partners and 6146 sales representatives across North America. We are not dependent on any one DistributionConstruction Partner or sales representative.

Strategic accounts are a cornerstone in our strategy to drive long-term sustainable and predictable growth. These types of clients manage large real estate footprints in numerous locations. For these clients it is advantageous and important to establish consistency in design and execution, repeatability, and speed to market. While these relationships can take time to develop, once they are established, the time and resources required to execute additional projects is reduced, which we believe will create profitable, predictable revenue streams. In return, clients benefit from a single point of accountability at DIRTT, a strong network of partners, full lifecycle support from established design standards and pre-construction expert support for their architects, designers and general contractors from field work to post installation support.

Manufacturing and Properties

Our DIRTT Solutions are currently manufactured at our facilities in Calgary, Alberta; Phoenix, Arizona;Alberta and Savannah, Georgia. OurOn February 22, 2022 we announced the closure of our Phoenix Facility in Arizona. On August 23, 2022, we announced the temporary suspension of operations at our Rock Hill, South Carolina Facility as the Calgary and Savannah Facilities can meet current demands. Currently our wall surfaces (which we call tiles)panels), millworkcasework and timber solutions are manufactured in Calgary, while aluminum, glass and power components are manufactured at all three locations.in Calgary and Savannah. Through distributed manufacturing we can shift production of some components among our manufacturing sites, reduce transportation times and costs, and meet targeted lead times. In 2019, we conducted an evaluation of our aluminum, tile and millwork capacities under various growth scenarios and concluded that the capacity of our aluminum manufacturing facilities is currently sufficient to support our anticipated growth. Given the longer lead time to acquire tile and millwork manufacturing equipment, combined with a lack of redundancy in those manufacturing facilities, we also concluded that we should commence construction of a new combined tile and millwork facility. In the fourth quarter of 2019, we entered into a lease for a building located inOur Rock Hill South Carolina, which will provide for approximately 130,000 square feet of manufacturing space for the combined tile and millwork factory. We currently expect construction of this factoryFacility has capabilities to be substantially completed and commissioned in the second quarter of 2021. Should the need arise, we have the expansion rights to lease an additional 130,000 square feet of space. Shouldproduce panels. If we experience additional growth, we may need to add or expand additional manufacturing facilities.facilities and resume operations at the Rock Hill Facility.

Suppliers and Raw Materials

Our inventory balances consist primarily of raw materials, which are kept on hand as components of our custom manufacturing process. Managing our raw material inventory is essential to our business, given our short lead times from order to shipment and our high level of order customization. Our key manufacturing materials are aluminum, hardware, wood and glass. For the twelve months ended December 31, 2020,2022, aluminum accounted for approximately 30.9%35% of our purchased materials, while hardware, wood and glassfinishing powder & paint accounted for approximately 14.1%12%, 11.2%12%, and 7.2%9%, respectively. While we maintain multiple suppliers for key materials, for the twelve months ended December 31, 2020,2022, (i) two suppliers accounted for approximately 28%38% and 24% of our aluminum supply, respectively, and two additional suppliers providing approximately 14% each (ii) two suppliers accounted for approximately 50%33% and 46%37% of our wood supply and(iii) one supplier accounted for approximately 41%94% of our paint & powder and (iv) one supplier accounted for approximately 38% of our hardware supply.

Materials are sourced domestically and, to a much lesser extent, overseas. Approximately 97%93% of our materials are manufactured and purchased in North America. Purchase decisions are made on the basis of quality, cost, quality and ability to meet delivery requirements. We do not typically enter into long-term agreements with suppliers. In general, adequate supplies of raw materials are available to all our operations and to date we have not been materially impacted by supply chain disruptions due to the COVID-19 pandemic, other than inflationary price pressures across substantially all of our raw material requirements, although aluminum purchases may be subject to market capacity constraints.

Technology and Development

We continue to focus on developing client-centric innovations and enhancements of both ICE Software and DIRTT Solutions with a primary focus on improving client experience, increasing market penetration and growing key markets. At December 31, 2020,2022, we employed 10590 employees within our technology and development groups and, including capitalized amounts, invested $10.3 million, $11.1 million and $11.6 million $11.3 millionin 2022, 2021 and $9.4 million in 2020, 2019 and 2018, respectively, in innovation activities.

Clients

Clients

DIRTT’s principal geographic markets are the United States Canada, and to a more limited extent, select international markets.Canada. Our revenue is derived almost entirely from projects in North America sold by our North American DistributionConstruction Partners.

Our revenue opportunities primarily come from commercial projects, including both new construction projects and renovations of existing buildings. Clients range from small owner-managed businesses to multinational Fortune 500 companies across a variety of industries, including healthcare, education, financial services, government and military, manufacturing, non-profit, energy, professional services, retail, technology, and hospitality. We view DIRTT Solutions as generally industry agnostic, with applications in many different industries with minimal adjustments. We are not dependent on any one client or industry segment. No single client represented more than 10% of our revenue for the years ended December 31, 2020, 20192022, 2021, or 2018.2020.

Competition

The overall market for interior construction is fragmented and highly competitive. The principal competitive factors in the interior construction industry include price (including cost certainty), speed, quality, customization, and service. Our main competitors are comprised primarily of conventional construction firms, individual tradespeople (including framers, drywall installers, and interior product designers) and modular systems manufacturers. Additionally, conventional construction firms are beginning to develop customizable wall paneling and other interior construction solutions and may directly compete with our DIRTT Solutions. We also compete with commercial furniture manufacturers, such as Teknion Corporation, Haworth Inc. and Allsteel Inc., who offer a variety of prefabricated interior wall solutions. We expect competition to increase as new entrants or solutions enter the interior construction market. See Item 1A. “Risk Factors”.

Seasonality

The construction industry has also historically experienced seasonal slowdowns related to winter weather conditions and holiday schedules, which affect shipping and on-site installation dates, in the fourth and first quarters of each calendar year. Our business has generally, but not always, followed this trend with a slight time lag, leading to stronger sales in the second half of the year versus the first half. Weather factors can also influence third-party exterior construction schedules and site conditions, which may in turn affect timing of interior renovations.builds.

Due to the fixed nature of certain of our manufacturing costs, such as our facilities leases and related indirect operating costs, periods of higher revenue volume tend to generate higher gross profit and operating income margins while periods of lower volume tend to result in lower gross profit and operating income margins. Quarters that contain consistent monthly manufacturing volumes tend to generate higher gross profit than those where manufacturing levels vary significantly from month to month.

Patent and Intellectual Property Rights

Our success depends, in part, upon our intellectual property rights relating to our products, production processes, our technology, including our ICE Software, and other operations. We rely on a combination of trade secret, nondisclosure and other contractual arrangements, as well as patent, copyright and trademark laws, to protect our proprietary rights and competitive advantage. We register our patents and trademarks as we deem appropriate and take measures to defend patents where we deem others are

11

infringing on our patents. The following table presents the status as of December 31, 20202022 of our issued and pending patents relating to various aspects of DIRTT Solutions and ICE Software:

Our issued patents expire between 20212024 and 2039. We do not believe that the expiration of any individual patent will have a material adverse effect on our business, financial condition or results of operations. As we develop innovations and new technology, we expect to file additional and supplemental patents to protect our rights in those innovations and new technology.

Sustainability and Environmental Matters

Conventional construction typically generates substantial waste. According to the Environmental Protection Agency’s 2018 Fact Sheet, approximately 189 million tons of building construction and demolition waste was generated in 2018, approximately 30% of which was related to wood products, drywall and plasters. Imprecise calculations or last-minute design changes may result in excess materials on the job site, such as wiring, drywall, wood, paint and flooring, that are sometimes unable to be reused or recycled. Measuring and cutting materials on-site leads to scrap waste that generally is sent to landfills. Sustainability is an integral component of our corporate brand identity and DIRTT Solutions. DIRTT Solutions are designed for disassembly, are form-fit and allow for less materials waste throughout the manufacturing and installation process. We integrate environmentally friendly elements into our business wherever possible, including utilizing solar energy at most of our factories to offset a portion of the cost of electricity and the environmental impact of our operations, and utilizing materials with high recycled content in our DIRTT Solutions. We also ship DIRTT Solutions with recyclable or reusable packing and shipping materials.

The adoption of environmentally responsible building codes and standards, such as the Leadership in Energy and Environmental Design (“LEED”) rating system established by the U.S. Green Building Council, also has the potential to increase demand for products, systems and services that contribute to building sustainable spaces. All of our DIRTT Solutions can contribute to the award of LEED credits and other green building rating systems. We continue to develop new products, systems and services to address market demand for products that enable construction of buildings that require fewer natural resources to build, operate and maintain. Our Enzo^TM line of wall components received the Canadian Green Building Council’s Green Building Product of the Year Award in 2015 due to its ingenuity and application, particularly as a benefit to healthcare facilities. With the help of Climate Earth Inc., in 2014 DIRTT was the first modular wall manufacturer to complete a full scope Life Cycle Assessment, resulting in 15 Environmental Product Declarations. In May 2019, we completed our second Life Cycle Assessment and released updated Environmental Product Declarations.

Government Regulations

The operation of our business is subject to stringent and complex laws and regulations pertaining to health, safety, and the environment. As an owner or operator of various manufacturing facilities, we must comply with these laws and regulations at the federal, state, provincial and local levels in both the United States and Canada. Failure to comply with environmental laws and regulations may trigger a variety of administrative, civil, or criminal enforcement actions, including the assessment of monetary penalties, the imposition of investigative or remedial requirements, or the issuance of orders limiting current or future operations. Certain environmental statutes impose strict, joint and several liability for costs required to clean up and restore sites where hazardous substances or industrial wastes have been mismanaged or otherwise released.

While we do not believe that compliance with federal, state, provincial, or local environmental laws and regulations will have a material adverse effect on our business, financial position or results of operations, we cannot provide any assurances that future events, such as changes in existing laws or regulations, the promulgation of new laws or regulations, or the development or discovery of new facts or conditions related to our operations will not cause us to incur significant costs.

Legal and Regulatory Proceedings

We may be involved from time to time in various lawsuits, claims, investigations, and other legal matters that arise in the ordinary course of business, including matters involving our products, intellectual property, relationships with suppliers, relationships with DistributionConstruction Partners, relationships with competitors, employees, and other matters. We may, for example, be a party to various litigation matters that involve product liability, tort liability, and claims under other allegations, including claims from our employees either individually or collectively. We do not believe that any current claims, individually or in the aggregate, will have a material adverse effect on our financial condition, liquidity or results of operations. For additional information regarding our current legal proceedings, see Item 3. “Legal Proceedings.”

Implications of Being an Emerging Growth Company

We are an “emerging growth company” as defined in the Jumpstart Our Business Startups Act (the “JOBS Act”) enacted in April 2012. Certain specified reduced reporting and other regulatory requirements are available to public companies that are emerging growth companies. These provisions include:

12

We will continue to be an emerging growth company until the earliest of:

We have elected to take advantage of certain of the reduced disclosure obligations in this Annual Report and may elect to take advantage of other reduced reporting requirements in future filings. As a result, the information that we provide to our shareholders may be different than what you might receive from other public reporting companies in which you hold equity interests. However, we have irrevocably elected not to avail ourselves of the extended transition period for complying with new or revised accounting standards and, therefore, we will be subject to the same new or revised accounting standards as other public companies that are not emerging growth companies.

Human Capital Resources

As of December 31, 2020,2022, DIRTT employed 1,013934 employees, 98%99% full time, 2%1% part time. We had 1,013922 full-time employees consisting of 606595 employees in production, 11574 employees in sales and marketing, 10590 employees in technology and development, 10290 employees in operations support, and 8573 general and administrative employees. At year-end, approximately 54%50% of our workforce are salaried employees and approximately 46%50% are compensated on an hourly basis. As of December 31, 2020,2022, approximately 32%28% of our workforce was based in the United States, and approximately 68%72% was based onin Canada. Our 20202022 hiring efforts were directed towards both our manufacturing and non- manufacturingnon-manufacturing functions. This reflects the build outstreamlining of our commercial organization, accounting for 30% of our new hires, and streamlining our operations space, accounting for 55%79% of our hiring activities. The Company’s recent gender diversity data shows that 25% (2021 – 28%) of our employees are female company wide. In 20202022 we hired 175213 employees, with 41%29% of new employees being female.

Diversity & Inclusion

DIRTT recognizes the importance of progressing conversations and initiatives around diversity and inclusion. “Grow through diversity” is one of our core values. Our strategy encompasses leadership training around key topics related to unconscious bias, allyship, and the value of attracting and retaining a diverse and inclusive organization. The strategy further focuses on the establishment and deployment of learning streams, mentoring circles, incorporatingand incorporation of inclusive language into our offer packages and benefit materials, and the implementation of a diversity counsel.materials. Our efforts begin at the early stages of the employee life cycle, where diversity candidates are highlighted and presented to hiring managers for review. We seek to hire based on talent, and skill, / capability needs, and fit. DIRTT has also incorporated diversity into various internal programs including succession planning and risk profiles.

Culture & Engagement

DIRTT has put new measures in place to assess and enhance the level of engagement and satisfaction of our employees. Specific activities include the deployment of a performance management tool, catered to drive discussions around team goals, performance and development opportunities, and greater transparency around policy and procedures, tied to cost and risk mitigation.

In the secondfourth quarter of 20202022, we deployed our firstbegan the implementation of a new employee engagement platform called Employee Voice that will deploy company-wide engagement surveysurveys focused on core themes of meaningful work, supportive management, positive work environment, growth opportunity, trust in leadershipworkplace civility, communication, work-life balance, retention, job satisfaction, employee engagement and mental health awareness.  

Targeteddiversity and inclusion. The platform and targeted initiatives wereare being put in place company widecompany-wide to assess the progression of themes from the survey on overall employee engagement and experience. Results from the fourth quarter of 2020 indicated an average positive increase of 4% enhancement of employee engagement through a variety of targeted measures.  

Additional initiatives that we attribute to the progression of culture and engagement include launching learning and development opportunities, enhanced communication platforms, employee recognition programs, and a company-wide philanthropic organization.  organization, and a strong focus on virtual social events to further support engagement and connection of remote employees.

Connecting to our community is a critical piece of the DIRTT story. Re-establishingWe continue to focus on establishing a stronger corporate social responsibilitycommunity investment program that demonstrates our drive to put community at the center of the business was a focus area in the third quarter of 2020.business. This involvedinvolves developing a strategy, carving out a roadmap of initiatives, and establishing a committee of 20 employees across the organization. As part of our strategy, we are focusing our efforts on establishing meaningful engagement opportunities, creating inclusive giving campaigns, driving sustainable impact, and enabling our employees to connect on philanthropic efforts. In the fourth quarter of 2020,2022, we kicked off

13

successfully completed our 2020 holiday giving campaign which was a coordinated in-person and virtual effort in support of foodbanksfood banks across North America.America, focusing on the cities in which we operate. The support for this campaign helped to reconnect DIRTT employees’ desire to give back with tangible outcomes for their communities. We take measures to address the mental health of our employees through a variety of company-wide initiatives.

Our core commitment to organizational safety resulted in a total recordable incident rateTotal Recordable Incident Frequency (“TRIF”) of 0.480.1 in 2020,2022, more than 75%97% below the industry average and a significant improvement from 4.90.5 TRIF in 2019.2021. Our enhanced health and safety protocols and robust contact tracing have been effective thus far in mitigating the spread of COVID-19 infections within our facilities and have helped us to avoid any material production disruptions.

We use a range of compensation incentives which vary by role, including:including annual variable compensation determined based on a combination of achieving team objectives and financial targets for the Company; quarterly bonuses for our manufacturing personnel paid on adherence to targets related to safety, quality, delivery, inventory and productivity; and commissions based on sales goals.sales. We also use various forms of stock-based compensation as a retention tool and to further align employee interests with the interests of our shareholders. We monitor our retention by way of voluntary turnover, which was 14%17% in 2020.2022.

In response to the COVID 19 pandemic, DIRTT established a business continuity and response committee to develop robust

company-wide COVID-19 protocols and guidelines. The committee has prepared easily accessible COVID-19 guidelines for all areas

of the business, including manufacturing, travel, client tours and day-to-day operations. In addition, we have established protocols for

reporting and contact tracing, and have limited access to our facilities, offices and other spaces to essential operations to minimize the

risk of exposure to COVID-19. We have also implemented enhanced cleaning protocols, increased signage, shift rotations in

cafeterias, limited headcounts in conference and meeting rooms, adopted policies with respect to essential workers, and work-from home guidelines and best practices, including ergonomics. In addition, we have taken measures to address the mental health of our

employees through a variety of company-wide initiatives. We also provide personal protective equipment to all of our employees, and

to clients that are engaged in essential tours. We have established a safety champions committee responsible for ensuring any

employee or visitor coming into our spaces is briefed on our COVID-19 protocols and guidelines. Lastly, we have implemented an app for reserving workspaces to help our employees adhere to our social distancing protocols, provide for greater support of contact tracing and ensure we adhere to capacity levels that will help us maintain safety protocols related to COVID-19.

None of our employees are covered by collective bargaining agreements. We have never experienced labor-related work stoppages or strikes, and we believe we currently have a positive relationship with our employees.

Item 1A. Risk Factors.

Investing in our common shares involves a high degree of risk. You should carefully consider the risks described below, as well as the other information in this Annual Report, including our consolidated financial statements and the related notes and Part II, Item 7. entitled “Management’s Discussion and Analysis of Financial Condition and Results of Operations,” and in any documents incorporated in this Annual Report by reference, before deciding whether to invest in our common shares. The occurrence of any of the events or developments described below could harm our business, financial condition, results of operations, and growth prospects. In such an event, the market price of our common shares could decline, and you may lose all or part of your investment. Although we have discussed all known material risks, the risks described below are not the only ones that we may face. Additional risks and uncertainties not currently known to us or that we currently deem immaterial may also impair our business operations. Certain statements below are forward-looking statements. See also “Special Note Regarding Forward-Looking Statements” in this Annual Report.

Risks Related to Our Business and Industry

TheOur business, financial condition, results of operations and growth could be harmed by the effects of the COVID-19 pandemic has had, and is expected to continue to have, a significant and adverse effect on our business.related government measures.

The COVID-19 pandemic has created significant volatility, uncertainty, and economic disruption. The extent to which COVID-19, or other public health pandemics or epidemics, impact our employees, operations, customers, suppliers, and financial results will depend on numerous evolving factors that we may not be able to accurately predict, including: the duration and scope of the COVID-19 pandemic (and whether there is a resurgence or multiple resurgences of the virus in the future, including as a result of strain variations); the actions taken by governments and public health officials in response to the pandemic; the availability and effectiveness of vaccines, approvals thereof and the speed of vaccine distribution; the impact on construction activity;activity (including related supply chain and labor shortages and their effects on construction schedules and timing); the effect on our customers’ demand for our DIRTT Solutions;solutions; our ability to manufacture and sell our products; and the ability of our customers to pay for our products. For example, while many of our products support life sustaining activities and essential construction, we, and certain of our customers or suppliers, may be impacted by state or provincial actions, orders and policies regarding the COVID-19 pandemic, including temporary closures of non-life sustaining businesses, shelter-in-place orders, and travel, social distancing and quarantine policies, the implementation and enforcement of which may vary by individual jurisdictions. On September 9, 2021, President Biden issued executive orders establishing, among other things, new vaccination requirements applicable to U.S. federal workers and contractors, large employers and healthcare workers. As a federal contractor, we are subject to the executive order. Although the Biden administration later updated its guidance to indicate that it will not enforce this vaccination requirement, additional vaccine mandates may be announced in jurisdictions in which our businesses operate. Our implementation of these rules may result in attrition, including attrition of skilled labor, and difficulty securing future labor needs. Additionally, our implementation of these rules may impact our ability to maintain satisfactory arrangements with third-party vendors and service providers, to the extent they are subject to vaccination requirements and they or their employees are unable or unwilling to comply. Any of thesethe foregoing events could have a material adverse effect on our business, liquidity or results of operations.

We are under the leadership of a reconstituted Board of Directors who are in the process of implementing a variety of operational, organizational, cultural and other changes to our business, and we may not be able to achieve some or all of the anticipated benefits of this transformation plan. We are also undergoing changes at a senior management level, including the appointment of a new Chief Executive Officer in June 2022.

Our Board of Directors was entirely reconstituted at our annual and special meeting of shareholders held on April 26, 2022 and, following that meeting, there was significant turnover in the Company's leadership. In addition to overseeing the changes to DIRTT’s leadership, the reconstituted Board of Directors has undertaken an extensive review of DIRTT’s operations, a process which is still ongoing (see Item 7. “Management’s Discussion and Analysis of Financial Condition and Results of Operations – Outlook”), and are in the process of implementing a variety of operational, organizational, cultural and other changes to our business, including plans to meet pipeline demand and expand revenues. The timely integration of senior management will be critical in the successful implementation of the Board of Directors' plans. We may not be successful in achieving some or all of the anticipated benefits of these plans, which may have an adverse effect on our results from operations and financial condition.

The effectiveness of certain elements of DIRTT’s administrative systems:

DIRTT has identified the need to upgrade its inventory management and cost accounting systems at some point in the future to enable scalable growth. Other information technology may require investment in the future. However, the success, in whole or in part, of this investment cannot be guaranteed.

15

We may not be successful in implementing our strategic plan or managing growth.growth

In November 2019, we unveiled a four-year strategic plan to scale our business based on three key pillars: commercial execution, manufacturing excellence and innovation. We have implemented several steps in furtheranceImplementation of our strategic plan, including improvements in our commercial function and enhancements to our product suite and software platform.  

While we are confident in our strategy implementation will require maturity of systems and processes across the organization. There is also no assurance that successful implementation will lead to sustainable, profitable growth, and may itself be disruptive to the Company. Failure to implement our strategic plan could materially and adversely affect our near-term sales, commercial activities, and ability to develop and sustain profitable growth. In addition, the success and timing of our implementation may be dependent upon external factors outside of our control, including the COVID-19 pandemic and its negative impact on construction activities as a whole. However, we remain confident that DIRTT’s value proposition will be as or even more relevant in the post-pandemic world.

Our strategy also depends in part on our ability to maintain and manage growth effectively. Growth in our headcount and operations may place significant demands on our management and operational and financial resources. Additionally, managing growth of our operations and personnel requires continuous improvement of our internal controls and reporting systems and procedures. Failure to effectively manage growth could result in difficulty providing current DIRTT Solutions and introducing future solutions, difficulty in securing clients and DistributionConstruction Partners, declines in quality or client satisfaction, increases in costs or other operational difficulties. Any of these difficulties could lead to a loss of investor confidence and adversely affect our business performance, financial condition and results of operations.

Our industry is highly competitive, and we may not be successful in educating potential clients about the benefits of our innovative and unique approach to interior construction as compared to traditionalconventional interior construction methods.

We operate in the highly competitive interior construction industry that is constantly developing and changing. We compete against conventional construction firms, individual tradespeople, and modular systems, and commercial furniture manufacturers. New market entrants and conventional construction firms are also beginning to develop customizable wall paneling and other modular interior construction solutions, and we expect this trend to continue. In addition, we may face pricing pressure from competitors or new market entrants who take on projects at reduced prices or employ other competitive strategies. While we believe our innovative design, quality, schedule and cost certainty, and network of DistributionConstruction Partners makes us well-positioned in the market, increasing competition could make it difficult to secure new projects at acceptable operating margins.

Our products are unique and offer an alternative to traditionalconventional construction techniques. Although offsite construction methods are gaining market acceptance, this still represents only a fraction of all construction methods and the overall construction market. Our ability to grow and increase market share depends, in part, on our success in continuing to increase demand for modular construction methods and products as an alternative to more traditional construction methods. While we intend to follow a strategy of innovative product development and strategic marketing efforts to enhance our position, there is no assurance that our solutions will attain a degree of market acceptance sufficient for sustained profitable operations. Failure to compete effectively by, among other things, meeting consumer preferences, developing and marketing innovative solutions, maintaining strong client service and distribution relationships, growing market share, and expanding our solutions capabilities could have a material adverse effect on our liquidity, financial condition, or results of operations.

Our former co-founders’ competitive behavior against us could have an adverse effect on our business, financial condition and results of operations.

Our co-founders and former executives, Mogens Smed and Barrie Loberg, have started an interior construction and manufacturing company that we believe competes with us. They, along with a number of our former employees and Distribution

Construction Partners who have joined their company have in-depth knowledge about our business, including our customers, employees, products and prospects, and we may be adversely affected by increased competition arising out of this business venture. We are engaged in litigation with Messrs. Smed and Loberg, entities with which they are involved, and other individuals relating to, among other things, enforcement of non-competition and non-solicitation obligations, alleged patent infringement, and alleged misappropriation of proprietary information by them or by us. See Item 3. “Legal Proceedings.”Note 20 to the Consolidated Financial Statements. If Messrs. Smed and Loberg further engage in a competitive business against us or if we are not successful in litigation, our business, financial condition and results of operations may be adversely affected.

We depend heavily on our network of DistributionConstruction Partners, and the loss or inattention of our DistributionConstruction Partners, or the failure of our DistributionConstruction Partners to meet their obligations to us, could materially and adversely affect our business, financial condition and results of operations.

We currently do not engage in many direct sales projects and rely almost exclusively on our network of DistributionConstruction Partners to promote brand awareness, sell and market DIRTT Solutions, and provide design, installation, distribution and other services to clients on each project. While we are not dependent on any single DistributionConstruction Partner, sales generated by approximately 10% of our DistributionConstruction Partners comprised approximately 40%39% of our total revenues for 2020.2022 (2021 – 40%). The loss of any top performing DistributionConstruction Partners, particularly to our competitors, may negatively affect our sales, financial condition or results of operations. It may further impair our ability to maintain a market presence in a particular geographic region until a new DistributionConstruction Partner relationship is established, which would require significant time and resources.resources, given DIRTT is typically a standalone line of business in their portfolio.

16

Although we provide our DistributionConstruction Partners with training, education, and support, they may be unable to successfully sell our DIRTT Solutions, execute projects or manage client experiences and relationships. In addition, our DistributionConstruction Partners and their clients may face financial difficulties or may become insolvent, which could result in the delay or cancellation of their plans to purchase DIRTT Solutions or lead to our inability to obtain payment of accounts receivable that they may owe. If we are unable to maintain a successful DistributionConstruction Partner network, our business, financial condition, and results of operations could be materially and adversely affected.

Increasing attention to environmental, social and governance (ESG) matters may impact our business

We have announced various voluntary ESG targets in our annual Environmental, Social, and Governance (ESG) report outlining our commitments to sustainability, the environment, health and safety, and diversity and inclusion. However, we may not be able to meet such targets in the manner or on such a timeline as initially contemplated, including, but not limited to, as a result of unforeseen costs or technical difficulties associated with achieving such results. Any actual or perceived failure to meet our ESG targets could adversely impact our reputation and our customers’ image of our products and result in the loss of business or impede our growth initiatives. Adverse publicity regarding ESG issues and similar matters, whether or not justified, could have a negative impact on our reputation and may result in the loss of customers and our inability to secure new customer relationships. Further, our customers may be more selective for products that meet their ESG goals or standards, such as increasing demand for goods that result in lower emissions, and our products could be less competitive if we are unable to meet these standards. Despite our efforts to adapt to and address these concerns, our efforts may be insufficient. Additionally, the implementation of these initiatives may increase our costs. It is difficult to predict how our efforts with respect to social and sustainability matters will be evaluated by current and prospective investors or by our customers or business partners.

Furthermore, public statements with respect to ESG matters are becoming increasingly subject to heightened scrutiny from public and governmental authorities related to the risk of potential “greenwashing,” i.e., misleading information or false claims overstating potential ESG benefits. For example, in March 2021, the SEC established the Climate and ESG Task Force in the Division of Enforcement to identify and address potential ESG-related misconduct, including greenwashing. Certain non-governmental organizations and other private actors have also filed lawsuits under various securities and consumer protection laws alleging that certain ESG statements, goals or standards were misleading, false, or otherwise deceptive. As a result, we may face increased litigation risk from private parties and governmental authorities related to our ESG efforts. In addition, any alleged claims of greenwashing against us or others in our industry may lead to further negative sentiment and diversion of investments. Additionally, we could face increasing costs as we attempt to comply with and navigate further regulatory ESG-related focus and scrutiny.

Risks Relating to Our Products and Software

We may be unsuccessful in designing, introducing, or selling new, innovative solutions, solution features, or software.

Our future success depends in part on our continuing ability to promote and demonstrate the value proposition of DIRTT Solutions, as well as our ability to develop and sell new, innovative solutions, solution features, or software that differentiate our solutions and achieve market acceptance in a timely and cost-effective manner. We incur significant costs associated with the investment in our research and development in furtherance of our strategy that may not result in increased revenue or demand for DIRTT Solutions and that could negatively affect our results of operations. Rapidly changing technology, evolving regulatory and industry standards, and changing consumer trends, demands, and requirements require us to continuously innovate and develop new, high-quality solutions, solutions features and software. Additionally, such rapid technological changes, standards and preferences could render the complex and proprietary technology of our software and solutions obsolete. We may also be unable to successfully address these developments on a timely basis, or at all. New solutions, solution features, or software may also be less successful than we anticipated, and such offerings may fail to achieve market acceptance. If we fail to respond quickly and cost-effectively to a changing market and changing consumer preferences, our competitive position, financial condition, and results of operations could be materially and adversely affected.

Our software and products may have design defects, deficiencies, or risks, and we may incur additional costs to fix any defects, deficiencies, or risks, or be subject to warranty or product liability claims.

Our software and solutions are complex and must meet the technical requirements of our clients and applicable building codes and regulations. Our solutions may contain undetected errors or design and manufacturing defects, and our software may experience quality or reliability problems, or contain bugs or other defects. Software defects may also cause errors in our manufacturing or miscalculations in ordering pricing and could lead us to incur losses and lose market share to competitors. Product or software defects could cause us to incur warranty costs, product liability costs, and repair and remediation costs. Although we maintain warranty reserves based on production, historical claims, and estimates, future warranty claims may exceed this amount. Similarly, while we maintain insurance of the types and amounts we consider commercially prudent and consistent with industry practice, such insurance coverage may not be sufficient to protect us against substantial claims. Such claims can be expensive to defend, could divert the attention of management and other personnel for significant periods, regardless of the ultimate outcome, and could result in negative

17

publicity. Increased costs to address product warranty claims or to defend against product liability claims may result in increased expenses and adversely affect our financial condition and results of operations.

We are subject to fluctuations in the prices of raw materials and commodities, which could adversely affect our liquidity, operating margins and financial condition.

We purchase raw materials, including aluminum, glass, and wood, from a number of local and global suppliers. The costs of these commodities can fluctuate due to changes in global supply and demand, speculationinflation, peculation in commodities futures, and changes in

tariffs or trade barriers, which can also interrupt supply. In addition, we have not historically entered into long-term agreements with vendors and may be exposed to short-term and long-term price fluctuations as a result.

Aluminum represents the largest component of our raw materials consumption. We have experienced fluctuations in the price of aluminum and anticipate that these fluctuations will continue in the future. Since 2018,In particular, during 2021 and 2022 we experienced significant price inflation across substantially all of our materials, largely due to pandemic-induced supply chain constraints, and it is unclear whether such price increases will be temporary or permanent in nature. From time to time, the U.S. government has imposed tariffs on steel and aluminum and limited the amounts of steel and aluminum coming into the United States based on the countries of origin of those imports. In 20192022 and 2020,2021, we sourced the majority of our aluminum from North America and sourced under 10% of our raw materials from outside North America. Nonetheless, substantial, prolonged upward trends in aluminum and other commodity prices, along with tariffs and import limitations, could significantly increase our costs and adversely affect our liquidity, operating margins, and financial condition.

We rely on a limited number of outside suppliers for certain key components and materials, and failure or delay in obtaining the necessary components or materials could delay or prevent the manufacturing or distribution of our DIRTT Solutions.

We rely on certain key suppliers for raw materials and components, including aluminum, glass, wood, paint, and hardware. We maintain multiple suppliers for key materials, although for the year ended December 31, 2020,2021, (i) two suppliers accounted for approximately 28%38% and 24% of our aluminum supply, respectively, and two additional suppliers provided approximately 14% each, (ii) two suppliers accounted for approximately 50%33% and 46%37% of our wood supply, and(iii) one supplier accounted for approximately 41%94% of our paint and powder supply, and (iv) one supplier accounted for approximately 38% of our hardware supply.supply. While we believe there are other vendors for most of our key requirements, certain materials and components meeting our quality standards are available only through a limited number of vendors. If we are required to obtain another source for these materials or components, we may not be able to obtain pricing on as favorable terms or on terms comparable to our competitors. Any failure or delay in obtaining the necessary raw materials or components in the quantities and quality required may result in increased costs and delays in manufacturing or distributing our products, which could have a material adverse effect on our liquidity, financial condition, or results of operations. A vendor may also choose, subject to existing contracts, to modify its relationship with us due to general economic concerns or specific concerns relating to that vendor or us, at any time. These modifications might include additional requirements from our suppliers that we provide them additional security in the form of prepayments or with letters of credit. Any significant change in the terms that we have with our key suppliers could materially and adversely affect our liquidity, financial condition, or results of operations.

Risks Relating to Market Conditions

Global economic, political and social conditions and financial markets may impact our ability to do business and adversely affect our liquidity, financial condition, and results of operations.

Our industry is cyclical and highly sensitive to macroeconomic conditions. Overall declines or reductions in construction and renovation due to economic downturns, unemployment and office vacancies, difficulties in the financial services sector and credit markets, and imposition of trade barriers can impact the demand for our products. Financial difficulties experienced by our suppliers, DistributionConstruction Partners or clients could also result in, among other things, inadequate project financing, project delays, inability to pay accounts receivable or disruptions in our supply chain. Any general economic, political, or social conditions that may contribute to financial difficulties experienced by us, our suppliers, DistributionConstruction Partners, or clients may adversely affect our liquidity, financial condition and results of operations.

We are exposed to currency exchange rates, interest rates, tax rates, and other fluctuations, including those resulting from changes in laws.

Our revenues and expenses are collected and paid in different currencies, including the U.S. dollar and Canadian dollar. Fluctuations in the relative values of any such currency expose us to foreign exchange risk and could have a material and adverse effect on our cash flows, revenues and results of operations. We also have currency exchange exposure to the extent of a mismatch between foreign-currency denominated revenues and expenditures – in particular, where U.S. dollar revenues do not equal U.S. dollar expenditures. We are not currently using exchange rate derivatives to manage currency exchange rate risks. There are currently no significant restrictions on the repatriation of capital and distribution of earnings to foreign entities from any of the jurisdictions in which we operate. There can be no assurance that such restrictions will not be imposed in the future.

18

Most of DIRTT's debt is on fixed interest rates. The Extended RBC Facility is subject to market interest rates. We are not currently using interest rate derivatives to manage interest rate risks. If interest rates rise this could have a material and adverse effect on our cash flows, revenues and results of operations and may adversely affect our ability to access financing.

Compliance with new or amended tax laws and regulations could have a material adverse effect on our business. We base our tax positions upon our understanding of the tax laws (including, applicable tax treaties) of the countries in which we have assets or conduct business activities. However, our tax positions are subject to review and possible challenges by taxing authorities, including as to the computation and allocation of income, transfer pricing and other complex issues. This includes adverse changes to the manner in which Canada, the United States and other countries tax local and foreign corporations and interpret or change their tax laws and applicable tax treaties.treaties, including in light of the increased focus by the U.S. Congress, the Canadian government, the Organization for Economic Co-operation and Development and other government agencies in jurisdictions where we do business on issues related to the taxation of multinational corporations. We cannot determine in advance the extent to which such jurisdictions may amend their tax laws, review our tax positions, or assess additional taxes or interest and penalties on such taxes. In addition, our effective tax rate may be increased by changes in the valuation of deferred tax assets and liabilities, our cash management strategies, local tax rates, or interpretations of tax laws.

Risks Relating to Intellectual Property and Information Security

We may be unable to protect our intellectual property adequately from infringement by third parties, and we may also be subject to claims that we infringe on intellectual property rights of others.

We rely on a combination of contract, copyright, patent, trademark and trade secret laws, confidentiality procedures and other measures to protect our intellectual property. There can be no assurance that our various patents, copyrights or trademarks will offer sufficient protection and prevent misappropriation of our proprietary rights in our products, software or processes. We also may not be granted patents, copyrights or trademarks on our pending or proposed applications, and granted applications may be challenged, invalidated or circumvented in the future. Despite our precautions, it may be possible for unauthorized third parties to copy our applications and use information that we regard as proprietary to create products or services that compete with ours. We enforce our intellectual property rights where appropriate, but the cost of doing so may be substantial and could outweigh the potential benefits, and we may be unsuccessful in our enforcement efforts. Failure to protect or maintain the proprietary nature of our intellectual property could adversely affect our ability to sell original products and materially and adversely affect our business, financial condition and results of operations.

Additionally, our competitors or other third parties may own or claim to own intellectual property in technology areas relating to our technology, including ICE Software, manufacturing processes, and DIRTT Solutions. Although we do not believe that our software or DIRTT Solutions infringe on the proprietary rights of any third parties, claims may arise regarding infringement or invalidity claims (or claims for indemnification resulting from infringement claims). Such assertions or prosecutions, regardless of their merit, may subject us to significant liabilities, require us to enter into royalty and licensing arrangements on unfavorable terms, prevent us from assembling or licensing certain of our products, subject us to injunctions restricting our sale of products, cause severe disruptions to our operations or the marketplaces in which we compete, or require us to satisfy indemnification commitments with our clients, including contractual provisions under various license arrangements. A damages award against us could include an award of royalties or lost profits and, if the court finds willful infringement, treble damages and attorneys’ fees. This may cause us to expend significant costs and resources, and could adversely affect our business, financial condition or results of operations.

If we are unable to protect our information systems against data corruption, cyber-based attacks or network security breaches, our operations could be disrupted and our reputation and profitability could be negatively affected.

In the ordinary course of our business, we generate, collect and store confidential and proprietary information, including intellectual property and business information. The secure storage, maintenance, and transmission of and access to this information is important to our operations and reputation. We use automated software and hardware solutions to protect our on-premise and cloud infrastructure; conduct routine third-party evaluations and vulnerability testing to identify and mitigate risks; and deploy training programs throughout the company. We have experienced cyber-based attacks, but to our knowledge, we have not experienced any material disruptions or breaches of our information technology systems or platforms. However, there is no guarantee that our security systems, processes or procedures are adequate to safeguard against all data security breaches, misuse of data, cyber-attacks, acts of vandalism, computer viruses, misplaced or lost data, programming or human errors or other similar events. Any security breach involving the misappropriation, loss or other unauthorized disclosure of confidential information of a client, DistributionConstruction Partner, employee, supplier or Company information could result in financial losses, exposure to litigation risks and liability (including regulatory liability), damage to our reputation, and disruptions in our operations, all of which could have a material adverse effect on our business, financial condition and results of operations. While we maintain cybersecurity insurance offor the types of coverage and amounts we consider it commercially prudent and consistent with industry practice, such insurance may not be sufficient to cover all losses relating to an information security breach.

19

The regulatory environment related to information security, data collection and use, and privacy is increasingly rigorous, with new and frequently changing requirements, and compliance with those requirements could result in additional costs. The costs associated with information security, such as increased investment in technology, the costs of compliance with privacy laws, and costs incurred to prevent or remediate information security breaches, could be substantial and adversely affect our business. A significant compromise of sensitive employee, DistributionConstruction Partner, client or supplier data in our possession could result in legal damages and regulatory penalties. In addition, the costs of defending such actions or remediating breaches could be material.

Damage to our information technology and software systems could impair our ability to effectively provide DIRTT Solutions and adversely affect our reputation, relationships with clients, financial condition and results of operations.

Our information technology and software networks and systems, which include the processing, transmission and storage of information, are integrated with our manufacturing processes and essential to our business operations. These systems are vulnerable to, among other things, damage or interruption from power outages, network failures or natural disasters, loss or corruption of data, human error, employee misconduct and difficulties associated with upgrades, installations of major software or hardware, and integration with new systems. While we maintain retention backups to geo-diverse digital and physical locations and have a recovery data center, the data center and other protective measures we take could prove to be inadequate. Any disruption in our systems or unauthorized disclosure of information could result in delayed manufacturing and delivery of our DIRTT Solutions, legal claims, a

loss of intellectual property and a disruption in operations, all of which could adversely affect our reputation, relationships with clients, financial condition and results of operations.

Risks Relating to Government Regulations and Enforcement

We may incur significant costs complying with environmental, health and safety laws and related claims, and failure to comply with these laws and regulations could expose us to significant liabilities, which could materially adversely affect our business and results of operations.

We are subject to laws, regulations, and other requirements with respect to workers’ health and safety and environmental matters in the United States, Canada and other countries in which we operate. Environmental laws and regulations impose, among other things, restrictions, liabilities and obligations in connection with the production, processing, preparation, handling, storage, transportation, disposal and management of wastes and other substances, and the prevention and remediation of environmental effects. Health and safety laws and regulations impose, among other things, requirements designed to ensure the protection of workers. New or more stringent laws and regulations, including those relating to climate change and greenhouse gas emissions, may be adopted in the future and could impact our facilities, raw material suppliers, the transportation and distribution of our solutions, and our clients, which could reduce demand for our solutions or cause us to incur additional operating costs. In addition, certain foreign laws and regulations may affect our ability to export products outside of or import products into the United States or Canada. Failure to comply with these requirements may result in civil or criminal liability, damages and fines, and our operations could be curtailed, suspended or shutdown and our reputation, ability to attract employees, and results of operations could be adversely affected. Private lawsuits, including claims for remediation of contamination, personal injury or property damage, or actions by regional, national, state and local regulatory agencies, including enforcement or cost-recovery actions, may materially increase our costs.

These factors may materially increase the amount we must invest to bring our processes into compliance with legal requirements and impose additional expenses on our operations. In addition, any changes in these laws or regulations or changes in our manufacturing processes may require us to request changes to our existing permits or obtain new permits. We may also be unable to obtain or maintain, from time to time, all required environmental regulatory approvals. A delay in obtaining any required environmental regulatory approvals or the failure to obtain and comply with such approvals could materially adversely affect our business and results of operations.

Risks Relating to Financial Results

We have had negative cash flow from operating activities.

We had negative cash flow from operating activities for prior years, including the years ended December 31, 2022 and 2021. Continued negative operating cash flow may compromise our ability to make interest and principal payments on the convertible unsecured subordinated debentures issued on January 25, 2021 and December 1, 2021 (collectively, the “Debentures”) on a timely basis, or at all, and to execute our strategic plan. Until we are able to generate positive cash flow from operating activities over a sustained period, our ability to finance our operations will be dependent on our cash reserves and available credit facilities and, if required, our ability to obtain additional external financing. Although we had $3.2 million in cash provided from operating activities during the fourth quarter of 2022 and we anticipate we will have positive cash flow from operating activities over at least the next twelve months, we cannot guarantee that such future cash flow will be sufficient or other changes to our circumstances will not necessitate additional financial resources to fund our operating activities.

In response to our negative cash flow from operations, on February 22, 2022, we commenced the process of closing our Phoenix aluminum manufacturing facility, shifting related manufacturing to both our Savannah and Calgary aluminum facilities. Additionally, we eliminated approximately 18% of our salaried workforce including manufacturing and office positions in February 2022, with

20

further reduction of 36 positions in July 2022. Additionally, to offset cost inflation on our materials, we implemented product price increases comprised of 5% effective November 1, 2021, 5% effective June 1, 2022, and a further 10% effective July 21, 2022. We have also undertaken several strategic actions and a Private Placement (as defined herein) to improve our balance sheet in the short term, see “Management's Discussion and Analysis of Financial Condition and Results of Operations–Liquidity and Capital Resources". Although we anticipate these actions will strengthen our balance sheet and liquidity position, we cannot guarantee that such future cash flow will be sufficient or other changes to our circumstances will not necessitate additional financial resources to fund our operating activities.

We have experienced a history of losses, and despite certain periods of profitability in recent years, we may not be able to generate sufficient revenue to achieve and sustain profitability.

We have incurred significant losses since commencing business. We incurred net losses of $11.3$55.0 million, $53.7 million and $4.4$11.3 million for the years ended December 31, 20202022, 2021 and 2019,2020, respectively. At December 31, 2020,2022, we had an accumulated deficit of $57.3$166.3 million. These losses and accumulated deficits were due in part to the substantial investments made to grow our business and acquire clients, to further develop our service offerings through product and software development, and to ensure that we have sufficient production capacity and capability to deliver on our commitment of rapid delivery times.times and to preserve our production, innovation and commercial capabilities through the economic disruption caused by the global COVID-19 pandemic in anticipation of a significant increase in construction activity as the pandemic impacts abate. Net loss for the year ended December 31, 2022 includes $13.5 million of restructuring costs associated with initiatives taken by the reconstituted Board and management to restructure the business and improve profitability and cashflows. Past results may not be indicative of our future performance, and there can be no assurance that we will generate net income in the future.

DIRTT's gross margins and resulting profitability have historically been negatively affected by the impacts of material cost inflation and the increased usage of discounting to drive higher demand. DIRTT has taken steps to improve gross margin by reducing discounts and increasing prices, including a 5% product price increase in Q4, 2021 and Q2, 2022 and a further 10% price increase in July 2022. Further, additional procurement and supply chain review procedures were established during the third quarter of 2022 to better monitor the volatility in our underlying material input costs. While the Company believes its pricing, discount structure and supply chain monitoring controls are sufficient, if we are unable to maintain or improve upon the gross profit margins delivered in the fourth quarter of 2022, if inflationary increases continue without corresponding increases in our pricing, or if such reduced discounting and price increases cause a material impact on demand, DIRTT’s results of operations and financial condition could be adversely impacted.

We have experienced, and may experience in the future, quarterly and yearly fluctuations in results of operations and financial condition.

Our results of operations and financial condition may continue to fluctuate from one quarter or year to another due to a number of factors, some of which are outside of our control. For example, we usually experience seasonal slowdowns in the first and fourth quarters of each calendar year, leading to stronger sales in the second half of the year versus the first half, and weather conditions may also delay delivery and installation on some projects. Furthermore, sales that we anticipate in one quarter may be pushed into another quarter, affecting both quarters’ results, and our actual or projected results of operations may fail to match our past performance. These events could in turn cause the market price of our common shares to fluctuate. In particular, if our results of operations do not meet the expectations of securities analysts or investors, who may derive their expectations by extrapolating data from recent historical results of operations, the market price of our common shares will likely decline. Due to our high fixed manufacturing costs and operating expenses, quarterly volatility in sales volumes could result in periods of low operating cash flow and negatively affect our liquidity. Due to these risk factors, quarter-to-quarter or year-to-year comparisons of our results of operations may not be an indicator of future performance.

We have recognized, and may recognize in the future, impairment charges for our goodwill and certain other non-current assets.

During the year ended December 31, 2021, we impaired the $1.4 million net carrying value of goodwill on our consolidated balance sheet. Significant negative industry or economic trends, disruptions to our business, planned or unexpected significant changes in the use of the assets, and sustained market capitalization declines may result in the impairment of non-current assets. For the past two years we have had an indicator of impairment for our non-current assets. Any further charges relating to impairments could have a material adverse impact on our results of operations in the period in which the impairment is recognized. We did not have any impairment charges for non-current assets during the year ended December 31, 2022.

21

Risks Related to Our Common Shares and Corporate Structure

Our share price has been and may continue to be volatile, which could cause the value of your investment to decline. If we fail to comply with the continuing listing standards of Nasdaq, our securities could be de-listed.

Our common shares are currently listed on the TSX under the symbol “DRT” and on Nasdaq under the symbol “DRTT.” The price of our common shares has in the past fluctuated significantly, and may fluctuate significantly in the future, depending upon a number of factors, many of which are beyond our control and may adversely affect the market price of our common shares. These factors include: (i) variations in quarterly results of operations; (ii) deviations in our earnings from publicly disclosed forward-looking

guidance; (iii) changes in earnings estimates by analysts; (iv) our announcements or our competitors’ announcements of significant contracts, acquisitions, strategic partnerships or joint ventures; (v) general conditions in the offsite construction and manufacturing industries; (vi) sales of our common shares by our significant shareholders; (vii) fluctuations in stock market price and volume; and (viii) other general economic conditions.

In the past, following periods of volatility in the trading price of a company’s securities, securities class action litigation has been brought against that company. If our share price is volatile, we may become the target of securities litigation in both the United States and Canada. Securities litigation could result in substantial costs and divert management’s attention and resources from our business and could have an adverse effect on our business, financial condition and results of operations.

Further, if the closing bid price of our common shares is below the $1.00 Nasdaq minimum requirement for 30 consecutive business days, we may become subject to de-listing proceedings. On September 7, 2022, we received a letter from Nasdaq that we have not been in compliance with the minimum bid price requirement set forth in Nasdaq Listing Rule 5450(a)(1) for a period of 30 consecutive business days. In accordance with Nasdaq Listing Rule 5810(c)(3)(A), we are provided a compliance period of 180 calendar days from the date of the notice to regain compliance with the minimum closing bid price requirement. If we do not regain compliance during the compliance period, we may be afforded a second 180 calendar day period to regain compliance if, among other things, we meet certain listing requirements of, and elect to transfer to, the Nasdaq Capital Market. We can achieve compliance with the minimum bid price requirement if, during either compliance period, the closing bid price per share of our common shares is at least $1.00 for a minimum of ten consecutive business days. We intend to monitor the closing bid price of our common shares and assess potential actions to regain compliance, but there is no assurance that we will be able to regain compliance, including under the specified time frames.

Any de-listing of our securities could have an adverse effect on the market price of, and the efficiency of the trading market for, our securities, not only in terms of the number of shares that can be bought and sold at a given price, but also through delays in the timing of transactions and less coverage of us by securities analysts, if any. Also, if in the future we were to determine that we need to seek additional equity capital, having been de-listed or being subject to de-listing proceedings could have an adverse effect on our ability to raise capital in the public or private markets.

We are governed by the corporate laws of Alberta, Canada, which in some cases have a different effect on shareholders than the corporate laws of the United States.

We are governed by the ABCA and other relevant laws, which may affect the rights of shareholders differently than those of a company governed by the laws of a U.S. jurisdiction, and may, together with our charter documents, have the effect of delaying, deterring or discouraging another party from acquiring control of our company by means of a tender offer, a proxy contest or otherwise, or may affect the price an acquiring party would be willing to offer in such an instance. The material differences between the ABCA and Delaware General Corporation Law (“DGCL”), that may have the greatest such effect include, but are not limited to, the following: (i) for certain extraordinary corporate transactions (such as amalgamations or amendments to our articles), the ABCA generally requires the voting threshold to be a special resolution passed by not less than two-thirds of the votes cast by the shareholders who voted in respect of the resolution, whereas DGCL generally only requires a majority vote; and (ii) under the ABCA, registered holders or beneficial owners (as defined in the ABCA) of not less than 5% of our common shares in aggregate can requisition our directors to call a special meeting of shareholders, whereas such right does not exist under the DGCL. We cannot predict whether investors will find our company and our common shares less attractive because we are governed by the corporate laws of Alberta, Canada.

Because we are a corporation incorporated in Alberta and some of our directors and officers are residents of Canada, it may be difficult for investors in the United States to enforce civil liabilities against us or our directors and officers based solely upon the federal securities laws of the United States. Similarly, it may be difficult for Canadian investors to enforce civil liabilities against our directors and officers residing outside of Canada.

We are a corporation amalgamated and existing under the laws of Alberta with our principal place of business in Calgary, Alberta, Canada. Some of our directors and officers are residents of Canada and a substantial portion of our assets and those of such persons are located outside the United States. Consequently, it may be difficult for U.S. investors to effect service of process within the United States upon us or our directors or officers who are not residents of the United States, or to realize in the United States upon judgments of courts of the United States predicated upon civil liabilities under the Securities Act.Act of 1933. Investors should not assume

22

that Canadian courts: (i) would enforce judgments of U.S. courts obtained in actions against us or such persons predicated upon the civil liability provisions of the U.S. federal securities laws or the securities or blue sky laws of any state within the United States or (ii) would enforce, in original actions, liabilities against us or such persons predicated upon the U.S. federal securities laws or any such state securities or blue sky laws.

Similarly, some of our directors and officers are residents of countries other than Canada and all or a substantial portion of the assets of such persons are located outside Canada. As a result, it may be difficult for Canadian investors to initiate a lawsuit within Canada against these non-Canadian residents. In addition, it may not be possible for Canadian investors to collect from these non-Canadian residents judgments obtained in courts in Canada predicated on the civil liability provisions of securities legislation of certain of the provinces and territories of Canada. It may also be difficult for Canadian investors to succeed in a lawsuit in the United States, based solely on violations of federal, provincial or territorial securities laws.

General Risks

Difficulties in recruiting and retaining qualified officers or employees, or experiencing labor shortages or disruptions, could have a material adverse effect on our business and results of operations.

Our success will depend in part on our ability to attract, develop, and retain qualified personnel as needed. We have undergone significant changes at a senior management level during the year as discussed elsewhere in this Annual Report. Although we anticipate smooth transitions, any changes to members of our senior management may be disruptive to our operations, including by diverting our Board’s and management’s time and attention and a decline in employee morale. If there are any delays in this process, our business could be negatively impacted. We may be affected by labor shortages or disruptions, particularly in locations where we operate manufacturing facilities. If we fail to attract or retain qualified personnel, or experience labor shortages or disruptions, we could incur higher recruiting expenses, a loss of manufacturing capabilities, or inability to respond to significant increases in demand, all of which could have a material adverse effect on our business and results of operations.

We may have additional capital needs in the future and may not be able to obtain additional capital or financing on acceptable terms.

We plan to continually invest in business growth and may require additional funds to respond to business opportunities, such as expanding our sales and marketing activities, developing new software, acquiring complementary businesses, products or technology,

and expanding or enhancing our manufacturing capabilities, including factory automation. To the extent that our existing capital is insufficient to meet our requirements, we may need to undertake equity or debt financings to secure additional funds. Further issuances of equity or convertible debt securities may result in significant share dilution. Additional new equity securities issued could have rights, preferences and privileges superior to those of our currently issued and outstanding common shares. Additional debt financings may involve restrictive covenants relating to our capital-raising activities and other financial and operational matters, which may make it more difficult for us to obtain additional capital and to pursue business opportunities. We cannot provide any assurance that sufficient debt or equity financing will be available for necessary or desirable expenditures or acquisitions, or to cover losses, and accordingly, our ability to continue to support our business growth and to respond to business challenges could be significantly limited, and our liquidity could be materially and adversely affected.

We may engage in future mergers, acquisitions, agreements, consolidations, or other corporate transactions that could adversely affect our business, financial condition, and results of operations.

While we currently have no specific plans to acquire any businesses, we may, in the future, seek to expand our business and capabilities through acquiring compatible technology, products or businesses. Additionally, we may explore other corporate transactions, including mergers, agreements, consolidations, or joint ventures, that we believe may be beneficial to our business or further specific business goals. Acquisitions involve certain risks and uncertainties, including, among other things, (i) difficulty integrating the newly acquired businesses and operations in an efficient and cost-effective manner; (ii) inability to maintain relationships with key clients, vendors and other business partners of the acquired businesses; (iii) potential loss of key employees of the acquired businesses; (iv) exposure to litigation or other claims in connection with our assumption of certain claims and liabilities of the acquired businesses; (v) diversion of management’s time and focus; and (vi) possible write-offs or impairment charges related to the acquired businesses. The occurrence of any of these risks could adversely affect our business, financial condition, and results of operations.

Item 1B. Unresolved Staff Comments.

Item 2. Properties.

Our principal executive offices are located in Calgary, Alberta, where we lease approximately 73,000 square feet of office and manufacturing space. Our lease expires in September 2022.2027. Our principal manufacturing facilities are currently located in Calgary,

23

Alberta; Phoenix, Arizona; and Savannah, Georgia. On February 22, 2022 we announced our intention to close the Phoenix manufacturing facility and DXC and on August 23, 2022 we announced our intention to temporarily suspend operations in Rock Hill, South Carolina as discussed in Item 1. “Business” in this Annual Report.

Our wall tiles, millworksurfaces (which we call panels), casework and timber solutions are manufactured in Calgary, while aluminum, glass and power components are manufactured in all three locations.Calgary and Savannah. In Calgary, we lease an aggregate of approximately 358,000400,000 square feet of manufacturing space across three facilities (excluding our principal offices), which leases expire in January 20232024 and January 2024.2026. In Phoenix, we lease approximately 130,000 square feet of manufacturing space across two facilities, which leases expire in March 20222027. We are currently utilizing the Phoenix space as a storage facility and March 2027.have sub-leased the remaining premises. In Savannah, we lease approximately 81,000 square feet of manufacturing space, which lease expires in February 2029. In October 2019, we entered into a 15-year lease, which DIRTT may extend for two additional 5 year periods at its option, for a combined tile and millworkpanel factory of approximately 130,000 square feet in Rock Hill, South Carolina. Should the need arise, we have the expansion rights to lease an additional 130,000 square feet of space. In March 2020, we entered into an 8 year lease, which DIRTT may extend an additional 5 years at its option, of approximately 18,000 square feet of space for a DXC in Dallas, Texas.

Our ICE development offices are located in Calgary, Alberta and Salt Lake City, Utah. In Calgary, we sublease approximately 8,700 square feet of office space pursuant to a lease that expires on July 31, 2021. In our Salt Lake City development office, which also houses a DXC, we lease approximately 6,600 square feet of office space pursuant to a lease that expires in December 2023. In New York City, New York, we lease approximately 4,100 square feet of space to operate a DXC; this lease expires in February 2024. In Chicago, Illinois, we own approximately 6,200 square feet of office space, which we use to operate a DXC.

Through distributed manufacturing, we can shift production of some components among our manufacturing sites, reduce transportation times and costs, and meet targeted lead times. We believe that our current and planned facilities are adequate for our current needs and that suitable additional or substitute space would be available if needed.

See Item 213. Legal Proceedings.

We arepursuing multiple lawsuits against our former founders, Mogens Smed and Barrie Loberg, their new company Falkbuilt Ltd. (“Falkbuilt”), and other related individual and corporate defendants for violations of fiduciary duties and noncompetition and non-solicitation covenants contained in their executive employment agreements, and the misappropriation of our confidential and proprietary information in violation of numerous Canadian and U.S. state, and federal laws pertaining to the protection of our trade secrets and proprietary information and the prevention of false advertising and deceptive trade practices.

As of December 31, 2022, our litigation against Falkbuilt, Messrs. Smed and Loberg, and their associates was comprised of three main lawsuits: (i) an action in the Alberta Court of Queen’s Bench instituted on May 9, 2019 against Falkbuilt, Messrs. Smed and Loberg, and several other former DIRTT employees alleging breaches of restrictive covenants, fiduciary duties, and duties of loyalty, fidelity and confidentiality, and the misappropriation of our confidential information (the “Canadian Non-Compete Case”); (ii) an action in the U.S. District Court for the Northern District of Utah instituted on December 11, 2019 against Falkbuilt, Smed, and other individual and corporate defendants alleging misappropriation of our confidential information, trade secrets, business intelligence and customer information (the “Utah Misappropriation Case”); and (iii) an action in the U.S. District Court for the Northern District of Texas instituted on June 24, 2021 alleging that Falkbuilt has unlawfully used our confidential information in the United States and intentionally caused confusion in the United States in an attempt to steal customers, opportunities, and business intelligence, with the aim of establishing a competing business in the United States market (the “Texas Unfair Competition Case”). We intend to pursue the cases vigorously.

In the Canadian Non-Compete Case, we have conducted extensive document production and questioning of the Notesdefendants that support our claims, as follows: (i) Smed and Loberg, and others, breached their duties owed to DIRTT, including their contractual and fiduciary duties; (ii) Smed, Loberg, and others began developing the Consolidated Financial Statements.new competing company immediately after Smed’s departure; (iii) before it was called Falkbuilt, the new competing company operated through a covert group comprised of then-current DIRTT employees and Construction Partners known as the TTIMit Group (which stands for “This Time I Mean It”); (iv) members of the TTIMit Group took steps to conceal their communications by creating and using alias names, using private and personal email addresses and phone numbers, and holding secret meetings and gatherings; (v) the TTMit Group also used then-current DIRTT employees to build out Falkbuilt's warehouse premises and offices, source and purchase equipment for Falkbuilt, assist with market research and develop Falkbuilt's products, build vignettes and drawings, address Falkbuilt's software and computer needs, and name Falkbuilt; and (vi) members of the TTIMit Group conspired together to solicit DIRTT employees and Construction Partners, design and sell competing products using DIRTT's confidential information, including DIRTT's pricing lists, DIRTT's product designs, DIRTT's personnel information, and revenue forecast information for DIRTT's Construction Partners. DIRTT is seeking, among other things, an order stopping the defendants from competing with DIRTT, judgment for damages and losses, and an accounting and disgorgement of the defendants' gains from their wrongful misconduct. In April 2022, DIRTT filed a summary judgment application seeking an expedited, pre-trial, final determination of our claims against the defendants. We expect this application to be heard in the first half of 2023.

24

In the Utah Misappropriation Case, the Court dismissed certain of the defendants, Falkbuilt Ltd., Falkbuilt, Inc. and Mogens Smed without prejudice, finding that Utah was an inconvenient forum. We appealed that ruling and the appeal was heard in November 2022. The remaining portion of the Utah Misappropriation Case is stayed pending resolution of the appeal.

In the Texas Unfair Competition Case, the Court dismissed our complaint finding that Texas was an inconvenient forum. We disagree with the decision and have filed a notice of appeal with the Fifth Circuit Court of Appeals. The appeal is stayed pending resolution of the appeal in the Utah Misappropriation Case.

Falkbuilt also filed a lawsuit against us on November 5, 2019 in the Court of Queen’s Bench of Alberta, alleging that DIRTT has misappropriated and misused their alleged proprietary information in furtherance of DIRTT’s product development. Falkbuilt seeks monetary relief and an interim, interlocutory and permanent injunction of DIRTT’s alleged use of the alleged proprietary information. We believe that the suit is without merit and filed an application for summary judgment to dismiss Falkbuilt’s claim.

Key Fourth Quarter 2022 Highlights

Summary of Financial ResultsKey Annual 2022 Highlights

Outlook

Annual revenue of $172.2 million fell just below the low end of the guidance range of $175 million to $185 million set during the second quarter of 2022, primarily driven by jobsite and project delays.

During 2022, our key focus was on stabilizing the Company’s balance sheet, slowing the pace of cash usage and implementing a number of initiatives designed to optimize both the cost and pricing structure. As early as the third quarter of 2022, we began seeing the improved financial effects of these changes. During the fourth quarter, this was even more magnified as Adjusted Gross Profit

The January 2023 pipeline is not only higher than January 2022, but we also believe it is healthier. The percentage of projects we believe are at the impactsstage of foreign exchange to improve year-on-year comparability of Adjusted EBITDA.

Outlook

On November 12, 2019, DIRTT unveiled a four-year strategic planthe project lifecycle where the project has been costed and budgeted for the Company, based on threenext twelve months has increased. Thus, while the macro-economic conditions impacting DIRTT continue to be volatile, we believe we have a better project outlook today, than one year ago. While we are encouraged by the pipeline growth, our order pace and quarterly revenue and supply chain forecasting continues to be challenged by the high push out rates and longer than normal engineering and design time associated with large and complex projects.

Our Construction Partners have been and remain a key pillars: commercial execution, manufacturing excellence and innovation. This plan laid out a roadmap to transform a founder-led start-up into a professionally managed operating company. Our long-term objective is to scale our operations to profitably capture the significant market opportunity created by driving conversion from conventional construction to DIRTT’s process of modular, prefabricated interiors.

Since its declaration as a global pandemic in March 2020, COVID-19 has had severe and ongoing impacts on commercial construction activity in North America, driven largely by regulatory responses implemented by governments and public health officials, lock-down measures and work-from-home requirements for non-essential workers. While commercial construction projects that were underway at the commencement of the pandemic generally continued to completion, albeit with some experiencing COVID-19 driven delays, North America experienced a significant contraction in the development of new projects as the pandemic took hold. As a result, DIRTT’s 2020 revenue declined 31% compared to 2019, driven largely by a 35% and 37% declineelement in our commercialgo-to-market strategy. Enhancing both partner effectiveness and education vertical sales, respectively, partially offset by more moderate declinesaccountability will again be a priority in our healthcare vertical. Quarterly revenues remained relatively consistent throughout 2020 as small projects and projects in process at the start of the pandemic were completed during the year.  

In early 2021, we experienced further softening2023. Our Construction Partners are a direct conduit to many of our commercial vertical sales. We expect this softness to continue through the first half of 2021 which reflects the aforementioned contraction in new project development, the continuation of a pronounced second wave of infections in North America with new lockdown measures and the inherent reluctance of end customers and we recommenced a Partner Advisory Council to commit to construction projects while such lockdownselevate partner feedback within our organization and work from home restrictions are ongoing. We are cautiously optimistic, however, that a recovery will begin in the second half of 2021 based on third-party industry indices combined with the general sentiment of our clients and partners and the commencement of major vaccination programs across North America.

While in general we have not seen a strong correlation between third-party indices and DIRTT performance given our low market penetration, and, thus, tend not to rely on these indices to manage our business, the scope and scale of the impact of the pandemic make such indicators more relevant for 2021. The Architecture Billing Index (ABI), which measures increases or decreases in architectural and design billings and is considered a leading indicator for non-residential construction activity nine to twelve months in the future, during 2020, reported an approximate 50% drop from the February to March and April periods with a significant recovery in September and October, albeit below expansion level. This improvement indicates the potential for a recovery in the second half of 2021. Similarly, Dodge Data & Analytics expects commercial construction to increase by approximately 5% in 2021.

Return to office planning is ongoing across North America as industry leaders recognize the need for in-person employee interaction to drive collaboration and innovation and address the inherent challenges and limitations of the current work-from-home environment. A critical consideration of this process is the office environment that employees are willing to return to and resulting

changes required thereto. Through our improved sales force, targeted marketing plans and strategic accounts, we are seeing increases in overall activityprovide further insight to support this planning activity. The timing of when this activity translates to sales is dependent upon when business leaders are willing to commit capital. Through the improvements we have made to our manufacturing operations, combined with the anticipated capacity and capabilities our new South Carolina facility, we expect to be poised and ready to deliver when these end customers commit to move forward.

Ultimately, we believe the long-term impact of COVID-19 will be a higher demand for flexible spaces that can be easily adapted post-installation. We expect that this will be a positive catalyst for the conversion from conventional site-built construction to the prefabricated, offsite solution provided by DIRTT. As a result, our objective throughout the pandemic has been to continue the prudent implementation of our strategic plan, while balancing the safeguards of our balance sheet and liquidity with our desire to enhance and improve our commercial and operational capabilitiesdecision making.

We continue to take advantageevaluate under-performing Construction Partners and are working to provide additional support and training to them. We have also placed an emphasis on those Construction Partners that have demonstrated a commitment to growth, commercial discipline, and collaborative success. We believe this approach will serve to strengthen our pipeline and provide a strong platform in which to drive better organic growth.

We are closely monitoring our cost structure, including the underlying materials that comprise our products. Although we believe we are insulated from the near-term effects of expected increases in demand when the recovery of non-residential construction occurs.

In early 2021 we took steps to further bolster our liquiditya recession in the faceUnited States or Canada, we are susceptible to the inflationary impact of continued uncertaintylabor and near-termcommodity pricing, particularly aluminum and wood.

In response to the risk associated with these items, we have taken additional actions over the past two months that will reduce annualized overhead costs by approximately $3 million to $5 million. These cost reductions are related to efficiencies and streamlining our back office and operational support functions, not pursuant to a planned restructuring program. We are also evaluating certain purchase arrangements that will hedge against inflation and volatility associated with our primary materials.

We believe that the combination of the growth in our sales softness. In January 2021, we completed a C$40.3 million (approximately $31.6 million) issuance of convertible debentures with a five-year termpipeline, the improved margins from pricing actions already taken and convertiblereduced cost structure set us up well to deliver year over year growth in revenue, gross margin and Adjusted EBITDA during 2023.

The Company’s current and immediate focus continues to be growing revenues, increasing profitability, and managing liquidity. Moving into common shares at a price of C$4.65 per share. In early February, we completed2023, the conversionfollowing items remain the focus of our undrawn existing cash-flow-based credit facilitymanagement team:

As many of our end customers continue implementing ‘return to work’ strategies, we have seen many cases where there is a strong need to modify their workspace to accommodate a more flexible environment in the need forshort-term, which in turn could change again over the medium- to long-term as post-pandemic requirements continue to evolve. Additionally, many organizations in different sectors are trying to enhance their physical presence in local communities by adopting a covenant holiday and ensuring future borrowing availability based upon accounts receivable and inventory balances.single design model that works in multiple jurisdictions. We believe we are well-positioned to capitalize on both trends.

In 2023, we expect to draw approximately $11 million on our existing equipment leasing facilitiesdeliver low to mid-single digit growth in the first half of 2021, financing the equipment purchases for our new South Carolina facility, largely paid for in instalments in 2019revenue and 2020.see higher gross margins, net income (loss) and Adjusted EBITDA compared to 2022. We also intend to apply for further government subsidy programs, including the Canadian Emergency Wage Subsidy program (CEWS) to the extent that it is applicable. In 2020, we qualified for $12.7 million of government subsidies of which $11.0 million was received with the balance expected to be received in 2021. This financial foundation provides the basis for usexpect to continue to executestabilize the balance sheet and grow unrestricted cash through a combination of improved financial performance and contribution from our strategic plan while the recoverynon-dilutive cash initiatives previously discussed.

We may opportunistically take actions to improve our debt and equity structure, though we anticipate that that Company's cash flows from the COVID-19 pandemic takes hold, enables us to avoid costly retrenchments of the transformational investments we have made,operations and increases our flexibility should the recovery take longer than expected.

Our commercial transformation is the key pillar of our growth strategy, against which we made significant progress in 2020.   This includes the hiring of personnel for key roles in the commercial organization and the establishment of both strategic marketing and strategic account and enterprise sales functions. We completed our Customer Relationship Management infrastructure buildout and are now in the process of rolling it out to all our sales representatives with full deployment expected in the first half of 2021. Our total cost of ownership tool, which provides an objective comparison with conventional construction, has been fully developed and deployed and further refinements and expansion of the tool’s capabilitiescurrent financing source will be a focus in 2021. During 2020 we added eight new Distribution Partners and expanded the territory of five others, mitigating the effects of partners who we chose to terminate due to performance or competitive issues. In 2021, we expect to build upon the work completed in 2020. This will include priority hires to drive enhanced market coverage, the buildout of our DXC in Dallas, with completion expected in the third quarter, the continuation of our strategic marketing campaigns focused on return to work and the nurturing of new and existing strategic account relationships.

Manufacturing excellence is the second pillar of our growth strategy. Our core commitment to organizational safety resulted in a TRIF of 0.48 in 2020, more than 75% below the industry average and included the Company’s first ever recordable incident-free quarter. Our enhanced safety protocols and robust contact tracing have been effective thus far in mitigating the spread of COVID-19 infections within our facilities and have helped us to avoid any material production disruptions. During 2020, we realized production efficiencies and yield improvements at both our aluminum manufacturing plants, and at our Calgary tile facility through changes in process flow. We also completed strategic sourcing agreements for major suppliers and enhanced quality and delivery processes. Having achieved continuous improvement by year end, in 2021, we will focus on the maturation and further integration of our processes to drive ongoing advancements in all areas of quality, delivery, inventory and productivity. We also remain on schedulesufficient for the commencement of commercial operations at our South Carolina tile facility in the second quarter of 2021.

The third pillar of our growth strategy is innovation. During 2020, in response to thecash needs of the pandemic, we developed four interior and exterior free-standing kiosks for COVID-19 testing and vaccinations, which we are currently marketing to healthcare organizations, retailers and large employers.  Regardless of whether these kiosks drive incremental sales, we believe they increase the prominence of our brand and demonstrate our overall capabilities to a new set of potential customers. From a software perspective, we released ICE 21, our most significant ICE release to date, allowing more people to experience ICEreality with added Android and Windows desktop platform capability and expanded functionality across a broader range of virtual reality head-mounted display hardware. In 2021, we expect innovation within our interior solutions and software to continue, including expanded functionality of our Inspire low profile modular and Reflect ultra-sleek glass wall solutions and ongoing improvements to the integration and core functionality of ICE.Company in 2023.

Throughout the last two years, we have made improvements in cost control and investment discipline which has served us well, particularly during the COVID-19 pandemic. In addition, we have benefited from reduced expenditures on travel and entertainment due to travel restrictions and deliberate reductions of certain discretionary expenditures until such time as the recovery occurs. Our capital expenditure program in 2021 is expected to total approximately $14 million, of which approximately $3.5 million relates to our

investment in the Dallas DXC, $3.0 million relates to the equipment and commissioning of our South Carolina tile and millwork facility, $3.0 million relates to the investments in our technology platform, with the remaining associated with  required maintenance capital and certain corporate initiatives.

In November 2019, our strategic plan articulated financial targets of $450 million to $550 million in revenue and 18% to 22% adjusted EBITDA margins to be achieved by the end of 2023. While the non-residential construction market is much less favorable than in late 2019 and our 2020 revenues were more than 30% below our 2019 revenues, the operating environment and transformation of the Company are sufficiently dynamic, which lead us to believe these goals are still achievable.

Non-GAAP Financial Measures

Note Regarding Use of Non-GAAP Financial Measures

Our consolidated financial statements are prepared in accordance with GAAP.accounting principles generally accepted in the United States of America (“GAAP”). These GAAP financial statements include non-cash charges and other charges and benefits that we believe are unusual or infrequent in nature or that we believe may make comparisons to our prior or future performance difficult.

As a result, we also provide financial information in this Annual Report that is not prepared in accordance with GAAP and should not be considered as an alternative to the information prepared in accordance with GAAP. Management uses these non-GAAP financial measures in its review and evaluation of the financial performance of the Company. We believe that these non-GAAP financial measures also provide additional insight to investors and securities analysts as supplemental information to our GAAP results and as a basis to compare our financial performance period-over-period and to compare our financial performance with that of other companies. We believe that these non-GAAP financial measures facilitate comparisons of our core operating results from period to period and to other companies by removing the effects of our capital structure (net interest income on cash deposits, interest expense on outstanding debt and debt facilities, or foreign exchange movements), asset base (depreciation and amortization), the impact of under-utilized capacity on gross profit, tax consequences and stock-based compensation. In addition, management bases certain forward-looking estimates and budgets on non-GAAP financial measures, primarily Adjusted EBITDA.

In the fourth quarter of 2019, we removedWe remove the impact of all foreign exchange from Adjusted EBITDA. Foreign exchange gains and losses can vary significantly period-on-periodperiod-to-period due to the impact of changes in the U.S. and Canadian dollar exchange rates on foreign currency denominated monetary items on the balance sheet and are not reflective of the underlying operations of the Company. We have presented a reconciliation to our prior calculationremove the impact of Adjusted EBITDA for all years presented. Additionally, in the fourth quarter of 2019, we excludedunder-utilized capacity from Adjusted Gross Profit costs associated with under-utilized capacity. Fixedgross profit, and fixed production overheads are allocated to inventory on the basis of normal capacity of the production facilities. In periods where production levels are abnormally low, unallocated overheads are recognized as an expense in the period in which they are incurred. In addition, management bases certain forward-looking estimates and budgets on non-GAAP financial measures, primarily Adjusted EBITDA.

Reorganization expenses, impairment expenses, governmentGovernment subsidies, depreciation and amortization, stock-based compensation andexpense, reorganization expenses, foreign exchange gains orand losses and impairment expenses are excluded from our non-GAAP financial measures because management considers them to be outside of the Company’s core operating results, even though some of those receipts and expenses may recur, and because management believes that each of these items can distort the trends associated with the Company’s ongoing performance. We believe that excluding these receipts and expenses provides investors and management with greater visibility to the underlying performance of the business operations, enhances consistency and comparativeness with results in prior periods that do not, or future periods that may not, include such items, and facilitates comparison with the results of other companies in our industry.

The following non-GAAP financial measures are presented in this Annual Report, and a description of the calculation for each measure is included.

31

You should carefully evaluate these non-GAAP financial measures, the adjustments included in them, and the reasons we consider them appropriate for analysis supplemental to our GAAP information. Each of these non-GAAP financial measures has important limitations as an analytical tool due to exclusion of some but not all items that affect the most directly comparable GAAP financial measures. You should not consider any of these non-GAAP financial measures in isolation or as substitutes for an analysis of our results as reported under GAAP. You should also be aware that we may recognize income or incur expenses in the future that are the same as, or similar to, some of the adjustments in these non-GAAP financial measures. Because these non-GAAP financial measures may be defined differently by other companies in our industry, our definitions of these non-GAAP financial measures may not be comparable to similarly titled measures of other companies, thereby diminishing their utility.

Revenue

The following table sets forth the contribution to revenue of our DIRTT Solutions and 2018related offerings.

In response to significant increases in the costs of raw materials, shipping materials, labor, and freight, effective November 16, 2021, DIRTT increased product and transportation prices on new projects by approximately 6.5%. On February 17, 2022, we implemented a further price increase of 5% that came into effect June 1, 2022. On June 21, 2022 an additional price increase of 10% was announced effective July 21, 2022. As of the fourth quarter of 2022, product sales reflect virtually all of these price increases. The first quarter of 2022 marked the transition of the COVID-19 pandemic to an endemic with the broad easing of health restrictions, including work-from-home mandates, across North America. While the resurgence in COVID-19 infections due to the Omicron variant at the beginning of the year temporarily sent many employees back to their home offices and delayed return dates, the Company and our Construction Partners experienced an uptick in planning activity and opportunity growth in our commercial vertical which began to translate into an increase in orders beginning in March 2022.

During the year ended December 31, 2022, revenue was $172.2 million, an increase of $24.6 million or 17% from the year ended December 31, 2021. The improvement in revenue was driven by the pricing actions and increased product demand discussed

above, offset by secured projects where the required shipment dates have pushed out due to stretched construction schedules increased. Further, 2021 revenue benefited from the price increases announced in November 2021, which motivated various customers to accelerate order and deliveries into 2021 to avoid the price increases. During the fourth quarter of 2022, we returned to a normalized seasonal demand pattern.

Installation and other services revenue was $5.9 million for the year ended December 31, 2022 compared to $4.6 million in the year ended December 31, 2021. This revenue primarily reflects services performed by our ICE and design teams for third parties. Except in limited circumstances, our Construction Partners, rather than the Company, perform installation services, and accordingly, we are not anticipating significant growth in this revenue stream.

Our success is partly dependent on our ability to profitably develop our Construction Partner network to expand our market penetration and ensure best practices are shared across local markets. At December 31, 2022, we had 67 (December 31, 2021: 69) Construction Partners servicing multiple locations. In February 2022, we announced the establishment of a Partner Advisory Council to provide a greater link with Construction Partners and end clients who they service. The Partner Advisory Council will offer advice on sales and marketing, product issues and new market needs, market conditions, competitive landscape, and other related areas of mutual interest.

We periodically analyze our revenue growth by vertical markets in the defined markets of commercial, healthcare, government and education. The following table presents our product and transportation revenue by vertical market.
