Please respond to these comments within ten business days by providing the requested information or advise us as soon as possible when you will respond. If you do not believe our comments apply to your facts and circumstances, please tell us why in your response. After reviewing your response to these comments, we may have additional comments. Form 8-K filed August 2, 2023 Exhibit 99.1, page 1 1. You present Adjusted EBITDA Margin in the bullet points at the top of Exhibit 99.1 without the presentation of the corresponding GAAP measure. Revise here and in your Q2 23 Summary Results tables in future Earnings Releases to also present gross margin on a GAAP basis. Ensure that your presentation of the GAAP measure is presented with equal or greater prominence than the non-GAAP measure. We refer you to Item 10(e) of Regulation S-K. 2. Your presentation of Adjusted Non-GAAP amounts appear to represent non-GAAP income statements. Please note that the presentation of a full non- GAAP income statement, or a presentation that gives the appearance of one, may place Glenn Coleman DENTSPLY SIRONA Inc. September 14, 2023 Page 2 undue prominence on the non-GAAP information and give the impression that the non- GAAP income statement represents a comprehensive basis of accounting. Please explain to us how your presentation complies with Question 102.10 of the C&DI's on Non-GAAP Financial Measures. To the extent you wish to present any of the non-GAAP measures, you could present a separate reconciliation for each non-GAAP measure and provide all disclosures required by Item 10(e)(1)(i) of Regulation S-K. In closing, we remind you that the company and its management are responsible for the accuracy and adequacy of their disclosures, notwithstanding any review, comments, action or absence of action by the staff.
