What Kestrel Group Ltd told the SEC could break it.

Kestrel/Maiden has acute counterparty concentration — AmTrust reinsurance was 38.7% of net premiums earned, and a single (unnamed) program-services client was 72.1% of fee revenue (with the second at 21.2%) — so loss of either relationship would materially hurt both revenue lines.

“During the year ended December 31, 2025, net premiums earned from AmTrust reinsurance agreements accounted for $ 4,908 or 38.7 % of total net premiums earned. During the year ended December 31, 2025, fee revenue from the Company's largest program services client accounted for $ 4,381 or 72.1 % of total fee revenue earned (2024: $ 3,390 or 93.3 %).”

Kestrel/Maiden Holdings has no significant operations of its own; dividends/distributions from subsidiaries (notably Maiden Reinsurance) are its sole source of funds for cash needs including 2013 Senior Notes debt service, and Vermont DFR requires prior approval of quarterly dividends — constraining upstreaming of cash.

“Dividends and other permitted payments from our operating subsidiaries are expected to be our sole source of funds to meet ongoing cash requirements at our subsidiaries, including debt service payments and other expenses.”

AmTrust North America holds a 30% minority interest in Kestrel LLC and provides professional/administrative services under a management agreement, and AmTrust insurance companies are a key capacity source — loss of AmTrust capacity could impair Kestrel's ability to write new business.

“t for the loss of any insurance capacity from the AmTrust Insurance Companies. Our inability to continue to write new business could materially and adversely affect our business, financial condition, results of operations and prospects.”

Kestrel's insurance/reinsurance subsidiaries are regulated across Bermuda, US states (Vermont DFR), Sweden and the UK with statutory capital requirements; in June 2025 the Swedish FSA declined to approve the sale of Maiden GF/LF, forcing an amended (GF-only) transaction still pending approval.

“In June 2025, the SFSA declined to approve the sale of Maiden GF and Maiden LF. The proposed acquirer whose application was denied by the SFSA and Maiden have now entered into an amended sale agreement for the acquisition of Maiden GF only at the previously agreed valuation.”
