Description of Business	DESCRIPTION OF BUSINESS FARO Technologies, Inc. and its subsidiaries (collectively “FARO,” the “Company,” “us,” “we” or “our”) design, develop, manufacture, market and support software driven, three-dimensional (“3D”) measurement, imaging, and realization solutions for the 3D metrology, architecture, engineering and construction (“AEC”) and public safety analytics markets. We enable our customers to capture, measure, manipulate, interact with and share data from the physical world in a virtual environment and then translate this information back into the physical domain. Our technology enables highly accurate 3D measurement, imaging, comparison and projection of parts and complex structures within production, assembly and quality assurance processes. Our FARO suite of 3D products and software solutions are used for inspection of components and assemblies, rapid prototyping, reverse engineering, documenting large volume or structures in 3D, surveying and construction, assembly layout, machine guidance as well as in investigation and reconstructions of crash and crime scenes. We sell the majority of our solutions through a direct sales force across a range of industries including automotive, aerospace, metal and machine fabrication, surveying, architecture, engineering and construction, public safety forensics and other industries. COVID-19 and Impact On Our Business Our business is significantly vulnerable to the economic effects of pandemics and other public health crises, including the ongoing novel coronavirus (“COVID-19”) pandemic that has surfaced in virtually every country of our global operating footprint. During 2020, we experienced a significant decline in the demand for our products and services across all of our served markets as a result of the impact of the spread of COVID-19. While COVID-19 has negatively impacted demand for our products and services overall, it has provided us with the opportunity to adapt to operating in a virtual environment. We significantly increased the utilization of our existing virtual sales demonstration infrastructure which has enabled ongoing customer product education. We launched an updated web-based learning system with FARO Academy that has resulted in an increase in the attendance of our virtual training and product information seminars as our customers take advantage of the opportunity to remotely participate and to better understand the capabilities of our products and software offerings. During 2021, we continue to assess the ongoing impact of COVID-19 on our business results and remain committed to taking actions to address the health and safety of our employees and customers, as well as the negative effects from demand disruption and production impacts, including, but not limited to, the following: •Operating our business with a focus on our employee health and safety, which includes minimizing travel, implementing remote work policies, maintaining employee distancing and enhancing the sanitation of all of our facilities; •Monitoring of our liquidity, reduction of supply flows into our manufacturing facilities, disciplined inventory management, and limiting capital expenditures; and •Continuously reviewing our financial strategy to enhance financial flexibility in these volatile financial markets. We continue to maintain a strong capital structure with a cash balance of $125.8 million and no debt as of September 30, 2021. We believe that our liquidity position is adequate to meet our projected needs in the reasonably foreseeable future. Future developments, such as the potential resurgence of COVID-19 in countries that have begun to recover from the early impact of the pandemic and actions taken by governments in response to future resurgence, are highly uncertain. Therefore, the Company is not able to predict the extent to which the COVID-19 outbreak continues to impact the Company’s results of operations and financial conditions.
