If our team can help one of your patients, please let me know. I specialize in the surgical treatment of cerebral aneurysms, carotid artery stenosis, intracerebral hemorr- hage, arteriovenous malformations and dural arteriovenous fistulas. Sincerely, Marsha Lawrence, MD Chair, Neurosurgery Medical Director, Neurosciences Institute at University Medical Center Inboxx 2/24/17, 11:02 AM OGGV We're ring a new surgic approach to correct visible defects in the skull after prior injury or previous craniotomy with minimized risk to the patient. The new technique, called pericranial-onlay cranioplasty, addresses most complex challenges in cranial res- toration by navigating the structures of the skin, subcutaneous layers, skull and dura to restore any calvarial bone by attaching either the original piece of the skull or a custom-contoured implant. Accept Invitation I would love to connect on Doximity. If you're interested in learning more about this new cranioplasty technique or if you would like to discuss a patient, please don't hesitate to call me on my mobile at (346) 245-3945.

Non-GAAP net income and non-GAAP net income margin are further adjusted for estimated income tax on such adjustments. We calculate income taxes on the adjustments by applying an estimated annual effective tax rate to the adjustments. Non-GAAP basic and diluted net income per common share is non-GAAP net income attributable to common stockholders divided by the weighted average number of shares. For both basic and diluted non-GAAP net income per share, the weighted average shares we use in computing non-GAAP net income per share is equal to our GAAP weighted average shares. Non-GAAP gross margin represents non-GAAP gross profit as a percentage of revenue and non-GAAP net income margin represents non-GAAP net income as a percentage of revenue. Adjusted EBITDA and adjusted EBITDA margin: We define adjusted EBITDA as net income before interest, income taxes, depreciation, and amortization, and as further adjusted for acquisition and other related expenses, stock-based compensation expense, change in fair value of contingent earn-out consideration liability, and other income, net. Adjusted EBITDA margin represents adjusted EBITDA as a percentage of revenue. Free cash flow: We calculate free cash flow as cash flow from operating activities less purchases of property and equipment and internal-use software development costs. We use these non-GAAP financial measures internally for financial and operational decision-making purposes and as a means to evaluate period-to-period comparisons. Non-GAAP financial measures are not meant to be considered in isolation or as a substitute for comparable GAAP financial measures and should be read only in conjunction with our consolidated financial statements prepared in accordance with GAAP. Our presentation of non-GAAP financial measures may not be comparable to similar measures used by other companies. We encourage investors to carefully consider our results under GAAP, as well as our supplemental non-GAAP information and the reconciliation between these presentations, to more fully understand our business. Please see the tables included at the end of this release for the reconciliation of GAAP to non-GAAP results. Key Business Metrics Net revenue retention rate: Net revenue retention rate is calculated by taking the trailing 12-month ("TTM") subscription-based revenue from our customers that had revenue in the prior TTM period and dividing that by the total subscription-based revenue for the prior TTM period. Our net revenue retention rate compares our subscription revenue from the same set of customers across comparable periods, and reflects customer renewals, expansion, contraction, and churn. Our net revenue retention rate is directly tied to our revenue growth rate and thus fluctuates as that growth rate fluctuates. The metric excludes the impact of the AMION acquisition, which closed on April 1, 2022, including customers of, and subscription revenue generated from, the AMION on-call scheduling and messaging application, and the impact of such acquisition was immaterial to the periods presented. Customers with trailing 12-month subscription revenue greater than $100,000: The number of customers with TTM subscription revenue greater than $100,000 is a key indicator of the scale of our business, and is calculated by counting the number of customers that contributed more than $100,000 in subscription revenue in the TTM period. Our customer count is subject to adjustments for acquisitions, consolidations, spin-offs, and other market activity, and we present our total customer count for historical periods reflecting these adjustments. The metric excludes the impact of the AMION acquisition, which closed on April 1, 2022, including customers of, and subscription revenue generated from, the AMION on-call scheduling and messaging application, and the impact of such acquisition was immaterial to the periods presented. doximity Proprietary 17#18APPENDIX: ADJUSTED EBITDA & MARGIN NON-GAAP RECONCILIATION¹ doximity Net Income Adjustments: Acquisition and other related expenses Stock-based compensation Depreciation and amortization Change in fair value of contingent earn-out consideration liability Income tax expense (benefit) Other income, net Adjusted EBITDA Revenue Adjusted EBITDA Margin Year Ended March 31, 2021 2022 (in thousands) $50,210 $154,783 496 7,252 3,702 254 31,442 5,040 7,559 (40,778) (4,466) (469) $64,753 $150,272 $343,548 $206,897 31% 44% 2023 $112,818 30 47,834 10,283 728 20,338 (8,048) $183,983 $419,052 44% 1.
