Disclosure of Certain Activities Under Section 13(r) of the Securities Exchange Act of 1934

Section 13(r) of the Securities Exchange Act of 1934, as amended, requires an issuer to disclose whether it or an affiliate engaged, inter alia, with individuals or entities sanctioned pursuant to certain Executive Orders during the period covered by the report. Certain activities must be reported even if they are not prohibited by U.S. law and were done outside the U.S. in full compliance with local laws.

Chubb, through certain of its non-U.S. subsidiaries, provides a broad range of insurance and reinsurance products worldwide. During the second quarter of 2026, Chubb identified that one of its non-U.S. subsidiaries issued automobile insurance policies to two persons designated pursuant to Executive Order 13224. One policy was issued in the fourth quarter of 2025, and the other in the second quarter of 2026.

Chubb also identified that, during the third and fourth quarter of 2025, a different non-U.S. subsidiary issued or renewed automobile insurance policies for two entities and travel insurance and accident and health insurance policies for one individual. Each of the insured parties was designated pursuant to Executive Order 13224.

In each case, the non-U.S. subsidiary froze the applicable policies and any related unearned premiums. Following designation, no claims were paid, and in the case of two automobile policies where premiums were received, the premiums were frozen. Gross revenues attributable to these policies were approximately USD equivalent $3,834.82, based on the applicable exchange rates. Net profits attributable to these policies are not precisely determinable but are less than the associated revenues. Chubb and its non-U.S. subsidiaries do not intend to provide any services to these persons in the future.
