For the three and six months ended June 30, 2026, amortization and impairment of acquired intangible assets totaled $168.2 million and $304.7 million, compared to $130.9 million and $242.7 million, respectively, in the prior year comparative periods.

For the three and six months ended June 30, 2026, amortization of acquired intangible assets, excluding impairment charges, totaled $168.2 million and $304.7 million, respectively, compared to $127.4 million and $239.2 million, respectively in the prior year comparative periods. The increases were primarily due to higher rates of amortization for the acquired intangible assets associated with SKYCLARYS. Additionally, we recorded $22.6 million of amortization for the acquired intangible assets as part of our acquisition of Apellis for the three and six months ended June 30, 2026.

For the three and six months ended June 30, 2026, we had no impairment charges. For the three and six months ended June 30, 2025, amortization and impairment of acquired intangible assets reflect the impact of a $3.5 million impairment charge related to a compound acquired from HI-Bio.

Completed technology primarily relates to our other marketed products and programs acquired through asset acquisitions, licenses and business combinations. In connection with our acquisition of Apellis we acquired completed technology with an estimated fair value of approximately $4.6 billion, comprised of $2.4 billion related to EMPAVELI commercialization rights in the U.S., $1.9 billion related to SYFOVRE commercialization rights and $380.0 million related to royalty rights associated with Sobi sales of EMPAVELI outside the U.S. under the brand name ASPAVELI.

Completed technology intangible assets are amortized over their estimated useful lives, which range between approximately 1 to 30 years, with a remaining weighted average useful life of 13 years as of June 30, 2026.

The estimated future amortization of finite-lived intangible assets for the next five years is expected to be as follows:
