SIGNIFICANT ACCOUNTING POLICIES AND BASIS OF PRESENTATION

NOTE 1 — SIGNIFICANT ACCOUNTING POLICIES AND BASIS OF PRESENTATION

Nature of Operations

First Citizens BancShares, Inc. (the “Parent Company” and, when including all of its subsidiaries on a consolidated basis, “we,” “us,” “our,” “BancShares”) is a financial holding company organized under the laws of Delaware that conducts operations through its banking subsidiary, First-Citizens Bank & Trust Company (“FCB”), which is headquartered in Raleigh, North Carolina. BancShares operates a network of branches and offices, predominantly located in the Southeast, Mid-Atlantic, Midwest and Western United States. BancShares provides various types of commercial and consumer banking services, including lending, leasing, and wealth management services. Deposit services include checking, savings, money market, and time deposit accounts.

BASIS OF PRESENTATION

Principles of Consolidation and Basis of Presentation

These consolidated financial statements and notes thereto are presented in accordance with instructions for Form 10-Q and Article 10 of Regulation S-X and, therefore, do not include all information and notes necessary for a complete presentation of financial position, results of operations and cash flow activity required in accordance with accounting principles generally accepted in the United States of America (“GAAP”). In the opinion of management, all normal recurring adjustments necessary for a fair presentation of the consolidated financial position and consolidated results of operations have been made. The unaudited interim consolidated financial statements included in this Quarterly Report on Form 10-Q (this “Form 10-Q”) should be read in conjunction with the Consolidated Financial Statements and Notes to the Consolidated Financial Statements included in our Annual Report on Form 10-K for the year ended December 31, 2024 (the “2024 Form 10-K”). Interim results are not necessarily indicative of results for a full year.

The consolidated financial statements of BancShares include the accounts of BancShares and its subsidiaries, certain partnership interests and variable interest entities (“VIEs”) where BancShares is the primary beneficiary, if applicable. All significant intercompany accounts and transactions are eliminated upon consolidation. Assets held in agency or fiduciary capacity are not included in the consolidated financial statements. Refer to Note 8—Variable Interest Entities for additional information regarding VIEs.

Reclassifications

Financial Statements

In certain instances, amounts reported in the 2024 consolidated financial statements have been reclassified to conform to the current financial statement presentation. Such reclassifications had no effect on previously reported stockholders’ equity or net income.

Changes to the Composition of Reportable Segments

We updated our segment reporting during the first quarter of 2025 (the “Segment Reporting Updates”) as we transferred certain components from the Silicon Valley Bank (“SVB”) Commercial and General Bank segments to the Commercial Bank segment and modified our segment expense allocation methodology. The Segment Reporting Updates did not result in the addition or removal of any of our existing segments at December 31, 2024, and the global fund banking and investor dependent loan portfolios, as well as a substantial portion of the cash flow dependent and innovation commercial and industrial (“innovation C&I”) loans, remain in the SVB Commercial segment. Segment disclosures for 2024 periods included in this Form 10-Q were recast to conform with the Segment Reporting Updates summarized above. Refer to Note 17—Segment Information for additional information.

2025 Loan Class Changes

At December 31, 2024, our disclosures for loans and leases and the allowance for loan and lease losses (“ALLL”) were aggregated into Commercial, Consumer, and SVB portfolios, each of which consisted of several loan classes as summarized below:

•The Commercial portfolio consisted of the following loan classes: commercial construction, owner occupied commercial mortgage, non-owner occupied commercial mortgage, commercial and industrial, and leases.

•The Consumer portfolio consisted of the following loan classes: residential mortgage, revolving mortgage, consumer auto, and consumer other.

•The SVB portfolio consisted of the following loan classes: global fund banking, investor dependent - early stage, investor dependent - growth stage, and cash flow dependent and innovation C&I.

For further descriptions of these loan classes, refer to Note 1—Significant Accounting Policies and Basis of Presentation in the Notes to the Consolidated Financial Statements included in our 2024 Form 10-K.

During the second quarter of 2025, the loan classes which were reported in the SVB portfolio in the 2024 Form 10-K were recast to the Commercial portfolio (the “2025 Loan Class Changes”) as summarized below:

•Global fund banking remained a separate loan class, but is reported under the Commercial portfolio.

•Investor dependent–early stage and investor dependent–growth stage were combined into a single investor dependent loan class, which is reported under the Commercial portfolio.

•Cash flow dependent and innovation C&I was combined with the commercial and industrial loan class, which is reported under the Commercial portfolio.

Loan and lease and ALLL disclosures for all periods presented in this Form 10-Q were recast to reflect the 2025 Loan Class Changes. Refer to Note 4—Loans and Leases and Note 5—Allowance for Loan and Lease Losses.

The disclosures in Note 17—Segment Information were not recast as a result of the 2025 Loan Class Changes because the composition of reportable segments is separate and distinct from the identification of loan classes.

Use of Estimates in the Preparation of Financial Statements

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions based on available information. These estimates and assumptions impact the amounts reported in the consolidated financial statements and accompanying notes and the disclosures provided, and actual results could differ from those estimates. The significant estimate related to the determination of the ALLL is considered a critical accounting estimate.

SIGNIFICANT ACCOUNTING POLICIES

Significant accounting policies are described in the 2024 Form 10-K. There were no material changes to these policies during the six months ended June 30, 2025.
