| • | Revenue of $1,023.8 million increased 1.2% for the quarter, or 0.4% in constant currency.  This compares to the guidance range of $1,000 to $1,010 million that the Company provided
                in early May. | 
| • | GAAP diluted EPS of $0.86 for the quarter increased 4.9%.  Non-GAAP EPS of $1.08 increased 1.9% and exceeded the high-end of the guidance range of $1.04 to $1.07 that the Company
                provided in early May. | 
| • | Diagnostics revenue of $448.9 million increased 1.8%, or 0.9% in constant currency, primarily driven by higher molecular diagnostics sales, partially offset by lower sales of
                COVID-19 assays. | 
| • | Excluding COVID-19 revenue, organic diagnostics sales grew 3.9%, or 2.9% on a constant currency basis. | 
| • | Molecular diagnostics revenue increased 3.2%, or 2.4% in constant currency, primarily driven by higher sales of the Company’s BV CV/TV and Panther Fusion assays. | 
| • | Excluding COVID-19 revenue, molecular diagnostics revenue grew 6.0%, or 5.2% on a constant currency basis.  This included 7.3% growth in the United States. | 
| • | Breast Health revenue of $365.2 million decreased (5.1%), or (5.8%) in constant currency, primarily driven by lower sales of mammography capital equipment, as expected.  This
                decline was partially offset by the inclusion of Endomagnetics revenue and increased service contract revenue. | 
| • | Organic breast health revenue, which excludes sales from the divested SSI and acquired Endomagnetics businesses, decreased (10.1%), or (10.8%) in constant currency. | 
| • | Surgical revenue of $178.4 million grew 7.1%, or 6.3% in constant currency, primarily driven by the acquired Gynesonics business and strong international sales. | 
| • | Organic surgical revenue, which excludes sales from Gynesonics, increased 2.0%, or 1.2% in constant currency. | 
| • | Cash flow from operations was a strong $343.2 million in the third quarter. | 
| • | The Company refinanced its term loan and revolving credit facility in July.  The facility now comprises a $1.17 billion term loan and a $1.25 billion revolver, and matures in July
                2030. |
