Revolving Line of Credit Extension

In February 2026, the Company amended the Credit Agreement to extend through June 2026. The extension also modified certain terms relating to covenant requirements.

Inorganic Growth

During the first quarter of 2026, Andersen entered into definitive agreements for the acquisition of four member firms located in the strategically important areas of Africa and Latin America and a business combination with one member firm located in the strategically important area of Canada. These transactions are expected to close in the second quarter of 2026, subject to the satisfaction of certain closing conditions.

Amendment of AT Umbrella LLC Agreement

On March 24, 2026, an amendment to the AT Umbrella LLC Limited Liability Company Agreement was executed. The amendment modified the redemption provisions of Class X Umbrella Units held by Aggregator, which allow for the Company to elect for settlement in cash instead of settlement in the Company's Class A common stock. Under the revised terms, the Company may elect to redeem Class X Umbrella Units held by Aggregator for cash only if the cash proceeds are sourced from a qualifying offering of its Class A common stock. As a result of these changes, the redeemable noncontrolling interest will be prospectively reclassified from temporary equity into permanent equity as the conditions for temporary equity classification are no longer met.
