On October 29, 2021, Hudson completed the acquisition of Karani, LLC (“Karani”), a Chicago-headquartered recruiting services provider that primarily serves U.S.-based customers from its operations in India and the Philippines. Karani partners with recruitment and staffing firms to assist with recruiting, sourcing, screening, onboarding, and other talent-related services across a variety of industries. This acquisition has enhanced the Company’s global delivery capability by adding a substantial presence in India and the Philippines, fostering business in new markets, and further developing the Company’s technology recruitment capabilities. On October 1, 2020, the Company completed its acquisition of Coit Staffing, Inc., which expanded its presence in the technology sector and established a Technology Group located in San Francisco. In addition to providing RPO services to clients in the tech sector, the Technology Group operates jointly with the Company’s existing teams in the Americas, Asia Pacific, and Europe to provide continuous access to knowledge regarding new and emerging technologies in the RPO, Managed Solutions Provider, and Total Talent Solutions spaces, enabling the Company to better serve its clients around the world. The Company operates directly in fourteen countries with three reportable geographic business segments: Americas, Asia Pacific, and Europe. See Note 14 to the Condensed Consolidated Financial Statements for further details regarding the reportable segments. In December 2019, a novel strain of coronavirus, referred to as COVID-19, was reported. On March 11, 2020, the World Health Organization declared the outbreak to be a pandemic, based on the rapid increase in exposure globally. Despite the decline in infection rates, the COVID-19 pandemic continues to have a lasting impact on various aspects of our business including but not limited to workforce shortages. Some countries around the world have imposed quarantines and restrictions on travel and mass gatherings to slow the spread of the virus. COVID-19 continues to have an impact around the world and presents risks to the Company, which the Company is unable to fully evaluate or foresee at the current time. However, the Company is vigilantly monitoring the business environment surrounding COVID-19 and continues to proactively address this situation as it evolves. The Company believes it can continue to take appropriate actions to manage the business in this challenging environment due to the flexibility of its workforce and the strength of its balance sheet.
