In calculating diluted net income per share, 851 thousand shares and 1.3 million shares related to outstanding stock options and unvested, undelivered restricted stock units were excluded for the three months ended March 31, 2024 and 2023, respectively. Additionally, for the three months ended March 31, 2024 and 2023, the interest expense and amortization of note costs relating to the shares issuable upon conversion of our outstanding convertible notes were excluded from the calculation as they would have been anti-dilutive. The interest expense including amortization of note issuance costs, related to convertible notes was $0.6 million for both the three months March 31, 2024 and March 31, 2023.
