Certara, Inc. 10-K

Item 2. Properties. As of December 31, 2021, we had 41 offices in 15 countries, with our headquarters located in Princeton, New Jersey. We lease or sublease all of our offices. None of our facilities are used for anything other than general office use. We believe that our facilities are suitable and adequate for our operations and we anticipate that additional suitable space will be available when needed. Because of the COVID-19 pandemic, in March 2020, we temporarily closed all of our offices. As of December 31, 2021, the majority of our offices have reopened, subject to a number of safety protocols consistent with local health authority guidance, such as requiring all employees accessing our U.S. offices to be fully vaccinated or limiting the number of employees who may be in a particular office at one time. We regularly reassess the safety protocols and use of specific offices based on the current prevalence of COVID-19 in a particular locale. We believe our employees have been able to maintain the same level of productivity in a remote working environment as they did prior to the pandemic, although we have seen a decrease in employee productivity as a result of the Omicron variant, which we believe will be temporary. We expect that most of our offices will re-open in some capacity once the current pandemic has abated. ​ As of December 31, 2021, our material operating locations, which we define as the facilities we lease with more than 10,000 square feet, were as follows: ​ ​ ​ ​ ​ ​ ​ ​ APPROXIMATE ​ LEASE EXPIRATION LOCATION SQUARE FOOTAGE DATES Wilmington, Delaware, USA ​ 18,250 ​ 2/28/2027 Princeton, New Jersey, USA 17,560 6/30/2025 Makati, Philippines 16,710 10/31/2022 Sheffield, UK 13,910 1/28/2028 Raleigh, North Carolina, USA 11,560 8/31/2022 ​ ​
