was driven primarily by the Insurance Distribution segment, reflecting the acquisition of ArmadaCare and organic revenue growth of 44%. Octave's net (loss) to shareholders for the second quarter of 2026 improved to $(14.4) million compared to $(20.5) million in the same prior-year period. The improvement was attributable to (i) our Insurance Distribution segment, which reported a net (loss) of $(3.7) million compared to $(7.7) million in the same prior-year period, (ii) our Specialty Property & Casualty segment, where Everspan reported net income of $1.1 million compared to $0.4 million in the same prior-year period, and (iii) a Corporate net loss of $(11.6) million compared to $(13.2) million in the same prior-year period. Adjusted net (loss) to shareholders for the second quarter of 2026 improved to $(1.8) million, compared to $(10.6) million in the same prior-year period. Adjusted EBITDA to shareholders for the second quarter of 2026 improved to $3.7 million, compared to $(4.6) million in the same prior-year period. The improvement in Adjusted EBITDA to shareholders was driven by a $7.3 million increase in Insurance Distribution Adjusted EBITDA to shareholders, reflecting organic growth across our core MGA platform, the acquisition of ArmadaCare, and an increase in our ownership position in Octave Ventures (formerly known as Beat Capital Partners) to 70% from 60%. In addition, Everspan's Adjusted EBITDA to shareholders increased $1.1 million to $1.8 million in the second quarter of 2026 from $0.7 million a year ago.

Assets included cash and liquid securities of $26 million and other investments of $22 million. Consolidated Octave Specialty Group, Inc. Stockholders' Equity and Noncontrolling Interests ("NCI") Impact to EPS Stockholders’ equity attributable to common shareholders at June 30, 2026, was $699 million, or $15.52 per share, compared to $713 million, or $15.83 per share, as of March 31, 2026. The decline was primarily a result of the total comprehensive loss attributable to common shareholders of $(12) million. Calculation of Earnings (Loss) Per Share (EPS) Diluted net income (loss) per share is computed by dividing net income (loss) attributable to shareholders, adjusted for the direct retained earnings impacts of changes to redeemable noncontrolling interests, by the basic weighted-average shares outstanding plus all potentially dilutive common shares outstanding during the period.

In addition to reporting the Company’s quarterly financial results in accordance with GAAP, the Company is reporting non-GAAP financial measures: EBITDA, Adjusted EBITDA and Adjusted EBITDA Margin, Organic Revenue Growth Rate (Insurance Distribution segment only), Adjusted Net Income and Adjusted Net Income Margin. These amounts are derived from our consolidated financial information, but are not presented in our consolidated financial results because they are not calculated in accordance with GAAP. We present non-GAAP supplemental financial information because we believe such information is of interest to the investment community, and that it provides greater transparency and enhanced visibility into the underlying drivers and performance of our businesses on a basis that may not be otherwise apparent on a GAAP basis. We view these non-GAAP financial measures as important indicators when assessing and evaluating our performance on a segmented and consolidated basis, and they are presented to improve the comparability of our results between periods by eliminating the impact of the items that may not be representative of our core operating performance. These non-GAAP financial measures are not substitutes for the Company’s GAAP reporting, should not be viewed in isolation, and may differ from similar reporting provided by other companies, which may define non-GAAP measures differently The following paragraphs define each non-GAAP financial measure. A tabular reconciliation of the non-GAAP financial measure to the most comparable GAAP financial measure is also presented below. Non-GAAP Financial Measures Organic Revenue Growth & Rate (Insurance Distribution Only) — Organic revenue is based on commissions and fees for the relevant period by excluding (i) the first twelve months of commissions and fees generated from acquisitions, (ii) commissions and fees from divestitures and (iii) other items such as contingent commissions, profit commissions and the impact of changes in foreign exchange rates. Organic Revenue Growth is the change in organic revenue period-to-period, with prior period results adjusted to (i) include commissions and fees that were excluded from organic revenue in the prior period and reached the twelve-month owned mark in the current period, and (ii) exclude commissions and fees related to divestitures from organic revenue. Total Specialty P&C Insurance Production includes gross premiums written by Octave's Specialty P&C Insurance segment and premiums placed by the Insurance Distribution 06/08/2026, 22:50 Octave Specialty Group - Octave Specialty Group Reports Second Quarter 2026 Results https://octavegroup.com/newsroom/news/news-details/2026/Octave-Specialty-Group-Reports-Second-Quarter-2026-Results/default.aspx 9/19

segment. Specialty P&C Insurance revenues are dependent on gross premiums written, as specialty program insurance companies earn premiums based on the portion of gross premiums written retained (i.e., net premiums written) and fees on gross premiums written that are ceded to reinsurers. Insurance Distribution revenues are dependent on premium volume, as Managing General Agents/Underwriters and brokers receive commissions based on the amount of premiums placed (i.e., gross premiums written on behalf of insurance carriers) with insurance carriers. EBITDA — EBITDA is net income (loss) from continuing operations before interest expense, income taxes, depreciation and amortization of intangible assets. EBITDA Margin — EBITDA divided by total revenues. Adjusted EBITDA and Adjusted EBITDA Margin — We define Adjusted EBITDA as net income (loss) from continuing operations before interest expense, income taxes, depreciation, amortization of intangible assets, change in fair value of contingent consideration and certain items of income and expense, including share-based compensation expense, acquisition and integration-related expenses, severance, and other exceptional or non-recurring items, including those related to raising capital. We believe that Adjusted EBITDA is an appropriate measure of operating performance because it eliminates the impact of income and expenses that may obfuscate business performance, and that the presentation of this measure enhances an investor's understanding of our financial performance. Adjusted Net Income and Adjusted Net Income Margin — We define Adjusted Net Income as net income (loss) from continuing operations attributable to shareholders adjusted for amortization of intangible assets, change in fair value of contingent consideration and certain items of income and expense, including share-based compensation expense, acquisition and integration-related expenses, severance and non-recurring income and loss items that, in the opinion of management, significantly affect the period-over-period assessment of operating results, and the related tax effect of those adjustments. Per share amounts exclude any impact of revaluing noncontrolling interests as otherwise reported under GAAP earnings per share. We believe that Adjusted Net Income is an appropriate measure of operating performance because it eliminates the impact of income and expenses that may obfuscate business performance.
