loan and greater financial flexibility to support future growth, representing total liquidity of $188.2 million as of September 30, 2021.
Working capital increased to $197.7 million as of September 30, 2021, and increase of $56.2 million from December 31, 2020, primarily as a result of normal working capital increases in accounts receivable and inventory given the seasonality of the business and the timing of new product launches.
Outlook
The Company expects to open approximately 100 new wellness centers in 2021 compared to its previously stated plan to open 130 to 170. The Company plans to begin construction on new wellness centers once all required in-center labor is hired given the current labor market. While the Company’s outlook remains suspended due to the uncertainty from potential COVID-19 and Delta-variant related impacts to its business, it continues to have record year-over-year net sales and adjusted EBITDA results. The Company is optimistic the Services segment will continue to generate significant improvements to its operations in the fourth quarter of 2021. As the impacts to the Company’s Services segment lessen and become more predictable, it will then be in a better position to provide formal guidance.
For the Products segment, the Company maintains its strong visibility to another year of solid sales growth and Adjusted EBITDA margin expansion. The Company continues to expect full year 2021 incremental EBITDA contribution from Capstar® of greater than $20 million. Long-term, the Company remains confident in achieving its strategic and financial objectives.
