In March 2024, the SEC adopted its Climate Disclosures Rules (refer to "Greenhouse Gas (GHG) Reporting Regimes" above). Those Rules, when effective, will require registrants to disclose certain climate-related information in registration statements and annual reports. Information required for inclusion within the footnotes to the financial statements for severe weather events and other natural conditions includes 1) income statement effects before insurance recoveries above 1% of pre-tax income/loss, 2) balance sheet effects above 1% of shareholders’ equity, and 3) certain carbon offsets and renewable energy credits. Qualitative discussion is also required for material impacts on financial estimates and assumptions that are due to severe weather events and other natural conditions or disclosed climate-related targets or transition plans.

Disclosures that are outside the financial statements include 1) Scope 1 and Scope 2 GHG emissions, if material, 2) how the Board of Directors oversees the assessment and management of climate-related risks, 3) management’s role in assessing and managing climate-related risks if the risks are material, 4) climate-related risks that have had or are reasonably likely to have a material effect on its business strategy, results of operations, or financial condition, including whether the risks are expected to manifest in the short term (i.e., next 12 months) and, separately, in the long term (i.e., beyond the next 12 months), 5) if a registrant has adopted a plan to manage material climate transition risks, the plan should be described and updated annually to specify its progress toward completing the transition plan, including any actions taken under the plan and how those actions

have affected the registrant’s business, results of operations, or financial condition, 6) if a registrant has adopted a plan to manage material climate transition risks, the plan should be described and updated annually to specify its progress toward completing the transition plan, including any actions taken under the plan and how those actions have affected the registrant’s business, results of operations, or financial condition, 7) quantitative price disclosures if a registrant uses an internal carbon price (e.g., a monetary cost assigned to carbon emissions for budgeting, forecasting, or performance management) and this use is material to how it evaluates material climate-related risks, 8) if a registrant uses a scenario analysis to assess its business in the context of climate-related risks and, on the basis of that analysis, determines that a climate-related risk is reasonably likely to have a material impact, the registrant must describe each scenario, including the parameters, assumptions, and projected financial impacts, 9) the registrant's processes for “identifying, assessing and managing” material climate-related risks, 10) information about the registrant's publicly announced or internal climate-related targets or goals if they materially affect or are reasonably likely to materially affect the registrant's business, results of operations, or financial condition (e.g., expenditures or operational changes needed to meet the targets or goals) and 11) quantitative and qualitative descriptions of the material expenditures incurred and material impacts on financial estimates and assumptions that, in management’s assessment, directly result from activities to mitigate or adapt to material climate-related risks.

PART I, ITEM 2. MANAGEMENT'S DISCUSSION & ANALYSIS (MD&A)

In April 2024, the SEC issued a stay of the Climate Disclosures Rules pending the completion of judicial review of various legal challenges. Therefore, the actual timing of the implementation of the Climate Disclosure Rules, if sustained through the judicial process, is uncertain. FHN is assessing the potential effects of the Climate Disclosure Rules on its registration statements and annual reports.
