During the years ended June 30, 2021 and 2020 we did not complete any material business combinations or record material acquisition-related expenses.

On November 13, 2018, we completed the acquisition of 100% of the shares in MatrixCare, Inc. and its subsidiaries (“MatrixCare”), a provider of software solutions for skilled nursing, life plan communities, senior living and private duty, for base purchase consideration paid of $750.0 million. This acquisition has been accounted for as a business combination using purchase accounting and included in our consolidated financial statements from November 13, 2018. The acquisition was paid for using borrowings under our revolving credit facility.

During the year ended June 30, 2019, revenues of $79.2 million and losses from operations of $9.1 million related to MatrixCare were included in the consolidated statement of comprehensive income. The losses from operations for the year ended June 30, 2019 was negatively impacted by $19.0 million of amortization of acquired intangible assets and fair value purchase price adjustments relating to deferred revenue of $5.3 million. Excluding the impact of these items, revenue for the year ended June 30, 2019 was $84.6 million and income from operations was $15.3 million.

The acquisition is considered a material business combination and accordingly unaudited pro forma information is presented below for the year ended June 30, 2019. The pro forma results were prepared using the acquisition method of accounting and combine our historical results and MatrixCare’s for the year ended June 30, 2019, including the effects of the business combination, primarily amortization expense related to the fair value of identifiable intangible assets acquired, interest expense associated with the financing obtained by us in connection with the acquisition, and the elimination of incurred acquisition-related costs.
