For the year ended December 31, 2022, our revenues were approximately $37.9 million, a decrease of $2.9 million, or 7.1%, compared with $40.8 million for year ended December 31, 2021. The current COVID-19 pandemic adversely affected many aspects of our business, including production, supply chain, and sales and delivery. Our manufacturing facility underwent temporary yet prolonged closure in February 2020 as part of China's nationwide efforts to contain the spread of the novel coronavirus. Even though our business is currently operational, our production capacity, delivery, warranty services including after-sale services and technical support, and operational efficiency are still adversely affected by the COVID-19 pandemic due to insufficient workforce in production, sales, and delivery as a result of temporary travel restrictions in China and the necessity to comply with disease control protocols in our business establishments and manufacturing facility. Our suppliers' abilities to timely deliver raw materials, parts and components, or other services were also adversely affected for similar reasons. The global spread of COVID-19 may also affect our overseas sales. As a result of varying levels of travel and other restrictions for public health concerns in various regions of China, we also temporarily postponed the delivery of our products to our customers. While the duration of the impact of the pandemic on our business and related financial impacts cannot be reasonably estimated at this time, our results of operations for the first half of 2020 were adversely affected with potential continuing impacts on subsequent periods. In addition, further outbreaks of the COVID-19 pandemic may adversely affect our PRC subsidiary's manufacturing ability, our PRC subsidiary's delivery and after-sale services in China. COVID-19 has had a global economic impact on the financial markets. The global spread of COVID-19 pandemic may result in global economic distress, and the extent to which it may affect our results of operations will depend on future developments, which are highly uncertain and cannot be predicted. We cannot assure you that the COVID-19 pandemic can be eliminated or contained in the near future, or at all, or a similar outbreak will not occur again. If the COVID-19 pandemic and the resulting disruption to our business were to extend over a prolonged period, it could materially and adversely affect our business, financial condition, and results of operations.
Global pandemics, epidemics in China or elsewhere in the world, or fear of spread of contagious diseases, such as Ebola virus disease (EVD), coronavirus disease 2019 (COVID-19), Middle East respiratory syndrome (MERS), severe acute respiratory syndrome (SARS), H1N1 flu, H7N9 flu, and avian flu, as well as hurricanes, earthquakes, tsunamis, or other natural disasters could disrupt our business operations, reduce or restrict our supply of products and services, incur significant costs to protect our employees and facilities, or result in regional or global economic distress, which may materially and adversely affect our business, financial condition, and results of operations. Actual or threatened war, terrorist activities, political unrest, civil strife, and other geopolitical uncertainty could have a similar adverse effect on our business, financial condition, and results of operations. Any one or more of these events may impede our production and delivery efforts and adversely affect our sales results, or even for a prolonged period of time, which could materially and adversely affect our business, financial condition, and results of operations.
We are also vulnerable to natural disasters and other calamities. We cannot assure you that we are adequately protected from the effects of fire, floods, typhoons, earthquakes, power loss, telecommunications failures, break-ins, war, riots, terrorist attacks, or similar events. Any of the foregoing events may give rise to interruptions, damage to our property, delays in production, breakdowns, system failures, technology platform failures, or internet failures, which could cause the loss or corruption of data or malfunctions of our manufacturing facility as well as adversely affect our business, financial condition, and results of operations.
