Basis of Presentation and Principles of Consolidation

The Company has prepared the accompanying unaudited condensed consolidated financial statements in accordance

with accounting principles generally accepted in the United States of America (“GAAP”) and the Securities and

Exchange Commission (“SEC”). References to the Accounting Standard Codification (“ASC”) and the Accounting

Standard Updates (“ASU”) included hereinafter refer to the Accounting Standards Codification and Updates issued

by the Financial Accounting Standards Board (“FASB”) as the source of the authoritative GAAP. In the opinion of

management, all adjustments (consisting of normal recurring adjustments) necessary for a fair presentation have

been included in these condensed consolidated financial statements.

The unaudited condensed consolidated financial statements include the accounts of the Company and its wholly-

owned subsidiaries, as well as variable interest entities (“VIE”) in which the Company is determined to be the

primary beneficiary. All intercompany balances and transactions have been eliminated in consolidation.

The condensed consolidated financial statements for prior periods give effect to the Corporate Contribution

discussed below, including the exchange of all 122,900 units of AIIG for an aggregate of 12,904,495 shares of

Common Stock of the Company, which is equivalent to an overall exchange ratio of one-for-105. All share and

earnings per share amounts presented herein have been retroactively adjusted to give effect to the Corporate

Contribution as if they occurred prior to all prior periods presented.

Initial Public Offering and Corporate Contribution

Immediately prior to the IPO, the owners of the equity interests of AIIG contributed all of their equity interests to

the Company in exchange for an aggregate of 12,904,495 shares of Common Stock in the Corporate Contribution.

On May 9, 2025, the Company completed its IPO of an aggregate of 6,875,000 shares of the Company’s Common

Stock, at a price to the public of $16.00 per share, 6,250,000 of which shares were sold by the Company and

625,000 of which shares were sold by certain selling stockholders. The gross proceeds to the Company from the IPO

were $100 million, and gross proceeds to the selling stockholders from the IPO were $10 million, before deducting

underwriting discounts and commissions of $7 million. Pending their further use, the proceeds were invested in

investment grade instruments. On May 13, 2025, the underwriters completed the exercise of their option to purchase

an additional 1,031,250 shares of Common Stock from the selling stockholders resulting in an additional $16.5

million in gross proceeds to the selling stockholders, before deducting underwriting discounts and commissions. The

Company did not receive any gross proceeds from the sales of shares of Common Stock by the selling stockholders.

In connection with the IPO, the Company issued a net amount of 417,470 shares of restricted stock to certain

employees and consultants (the “Restricted Stock Grant”) after giving effect to the withholding of approximately

234,587 shares of Common Stock to satisfy the estimated tax withholding and remittance obligations (the

“Restricted Stock Grant Net Settlement”). The Company incurred a one-time share-based compensation expense of

$10.4 million in connection with the Restricted Stock Grant, which was expensed in general and administrative

expenses on the condensed consolidated statements of operations and comprehensive income. The Company also

paid $3.8 million for tax withheld on the vesting of restricted stock in connection with the Restricted Stock Grant

Net Settlement. The compensation expense for these awards was recognized in the second quarter of 2025.

Use of Estimates

The preparation of condensed consolidated financial statements in conformity with GAAP requires management to

make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the condensed

consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. As

a result, actual results could differ from those estimates. Management evaluates estimates on an ongoing basis when

updated information related to such estimates becomes available. The most significant areas that require

management judgment are the estimate of unpaid losses and loss adjustment expenses, evaluation of reinsurance

recoverable, evaluation of ceding commission, and valuation of investments.
