Cost of collaborations and royalties Cost of collaborations and royalties increased during the year ended December 31, 2023, as compared to the year ended December 31, 2022, primarily due to increased demand of GalNAc material supplied to our collaborators to support certain product manufacturing and ongoing clinical trials and increased royalties payable to third parties on the net sales of licensed products by Novartis.
Cost of Collaborations and Royalties Cost of collaborations and royalties decreased during the year ended December 31, 2024, as compared to the year ended December 31, 2023, primarily due to decreased demand for GalNAc material supplied to our collaborators in support of certain 81 Table of Contents product manufacturing as our collaborators transition to producing the material independently, as well as reduced royalties payable from the expiration of licenses of third-party intellectual property.

We expect our cost of collaborations and royalties will decrease during 2024, as compared to 2023, primarily due to a decrease in demand of GalNAc material supplied to our collaborators in support of certain product manufacturing as our collaborators begin to transition to producing the material independently. 86 Table of Con tents Research and Development Research and development expenses consist of the following: Year Ended December 31, 2023 vs 2022 2022 vs 2021 (In thousands, except percentages) 2023 2022 2021 $ Change % Change $ Change % Change Clinical research and outside services $ 485,732 $ 438,418 $ 418,985 $ 47,314 11 % $ 19,433 5 % Compensation and related 260,423 225,589 196,134 34,834 15 % 29,455 15 % Occupancy and all other costs 160,987 126,847 108,622 34,140 27 % 18,225 17 % Stock-based compensation 97,273 92,161 68,415 5,112 6 % 23,746 35 % Total $ 1,004,415 $ 883,015 $ 792,156 $ 121,400 14 % $ 90,859 11 % Research and development expenses increased during the year ended December 31, 2023, as compared to the year ended December 31, 2022, primarily due to the following: • Increased compensation and related expenses as a result of increased headcount to support our R&D pipeline and development expenses; • Increased clinical research and outside services primarily associated with zilebesiran as we reached full enrollment for our KARDIA-1 and KARDIA-2 clinical studies and additional costs associated with manufacturing batches associated with those clinical activities.

Our collaborator is eligible to receive tiered royalties of 15% to 30% based on global annual net sales and therefore the growth in AMVUTTRA net sales during 2023 resulted in more net sales and a higher tier rate for the applicable royalties payable; and • Increased excess and obsolete charges primarily due to cancelling manufacturing commitments and the impairment of ONPATTRO inventory that had been manufactured for future demand associated with the use of patisiran for the treatment of patients with ATTR amyloidosis with cardiomyopathy for which we did not receive regulatory approval in the U.S.
Approximately 5.0% of the 21.6% of cost of goods sold as a percentage of net product revenues for the year ended December 31, 2023 was attributable to cancelled manufacturing commitments and the impairment of ONPATTRO inventory that had been manufactured for future demand associated with the use of ONPATTRO for the treatment of patients with ATTR amyloidosis with cardiomyopathy, for which we did not receive regulatory approval in the U.S.
