 disclosures included in the Company’s Form 10-Kfor the year ended December 31, 2024:

| • |     | while we included a discussion of methods and key assumptions used, and the degree of uncertainty associated with                                                                       
 such assumptions including within Item 7, Management’s Discussion and Analysis of Financial Condition and Results of Operations,1 we will further emphasize any considerations that are 
 uniquely applicable to a reporting unit at risk of failing; and                                                                                                                         |

| • |     | we will expand the statement in Note 10. Goodwill2 to                                                                                                           
 also include a description of more specific events and/or changes in circumstance that could reasonably be expected to negatively affect these key assumptions. |

In addition, we will disclose the following points more comprehensively in future filings, to provide more information for investors to further assess the probability of future impairment charges, as applicable:

| • |     | the percentage by which fair value exceeded carrying value as of the most recent test date for a reporting unit 
 at risk of failing; and                                                                                         |

| • |     | we will highlight that the Company’s reporting units are aligned with its operating and reportable segments, 
 for which allocated goodwill is disclosed, as required.                                                      |

The Company monitored a share price decline of approximately 37% from November 6, 2024 (one day prior to the Q3 2024 Earnings Call) to December 31, 2024. However, given the short duration, the decline was not considered sustained as of December 31, 2024, and there were no other significant changes in events, circumstances, or key assumptions which would indicate that the carrying value of goodwill was not recoverable. From December 31, 2024, through March 1, 2025, the Company’s share price declined an additional approximately 38% (an approximately 61% decline in total from November 6, 2024 through March 1, 2025), leading the Company’s management to conclude that such share price decline was sustained. Accordingly, in connection with the Company’s review and preparation of its financial statements for the quarter ended March 31, 2025, management determined that an interim quantitative goodwill impairment test was necessary as of March 1, 2025.
