The changes in our working capital primarily reflect the use of cash in operating activities, as well as an increase in inventory due to the capitalization of ELEVIDYS inventory after its approval in June 2023.
The changes in our working capital for both periods primarily reflect use of cash in operating activities, as well as a reduction in our cash, cash equivalents and investments to fund the Arrowhead Payments in 2025.
The decrease was primarily driven by the following: - 76 - • $16.8 million decrease in manufacturing expenses primarily due to the capitalization of commercial batches of ELEVIDYS manufactured upon its approval in June 2023, a decrease in clinical batches for our PPMO platform as a result of our decision to discontinue our PPMO programs during 2024, partially offset by $91.9 million of costs associated with the termination of the development, commercial manufacturing and supply agreement (the “Thermo Agreement”) related to Brammer Bio MA, LLC, an affiliate of Thermo Fisher Scientific, Inc.
The remaining increase relates to $300.0 million of milestone payments to Arrowhead, triggered by Arrowhead's achievement of the DM1 Milestones, with no similar activity in 2024; • $120.2 million decrease in manufacturing expenses primarily due to costs associated with the termination of the development, commercial manufacturing and supply agreement (the “Thermo Agreement”) related to Brammer Bio MA, LLC, an affiliate of Thermo Fisher Scientific, Inc.

The net cash outflow from changes in our operating assets and liabilities was primarily driven by the following: - 81 - • $185.7 million increase in accounts receivable due to the launch of ELEVIDYS and an increase in the demand of our PMO Products; • $147.7 million increase in inventory primarily due to capitalized inventory related to ELEVIDYS; • $86.8 million decrease in deferred revenue primarily related to the collaboration with Roche; • $50.1 million decrease in accounts payable, accrued expenses, lease liabilities and other liabilities, primarily due to the $54.0 million shortfall payment to Thermo and payments to Catalent for raw materials in 2023 and the overall timing and invoicing of payments; and • $12.5 million increase in manufacturing-related deposits and prepaids primarily due to the timing and usage of manufacturing prepaids.
The net cash outflow from changes in our operating assets and liabilities was primarily driven by the following: • $301.1 million increase in inventory primarily due to capitalized inventory related to ELEVIDYS; • $203.8 million decrease in accounts receivable primarily due to reduced shipments of ELEVIDYS in the second half of 2025 compared to 2024 due to the ELEVIDYS Suspension; • $79.8 million increase in other assets primarily due to the timing of billings to Roche for orders of ELEVIDYS for use outside of the U.S., as well as increased royalty receivables from Roche related to increased ELEVIDYS sales outside of the U.S.; • $104.3 million increase in accounts payable, accrued expenses, lease liabilities and other liabilities primarily due to the remaining $200.0 million associated with the Arrowhead DM1 Milestones being included in accounts payable as of December 31, 2025, partially offset by a reduction in accrued employee compensation costs pursuant to our Restructuring and payments on accrued employee compensation costs, a reduction in accrued income taxes and the timing and invoicing of payments with our contract research organizations and contract manufacturing organizations; • $72.1 million increase in deferred revenue primarily related to the timing of billings to Roche for orders of ELEVIDYS not yet shipped, partially offset by the recognition of collaboration revenue related to the expiration of an option for a certain program previously recorded as deferred revenue; and • $78.8 million decrease in manufacturing-related deposits and prepaids primarily due to the use of raw materials and services previously prepaid with Catalent and Aldevron.
For 2024, we recognized $48.0 million in collaboration revenue related to Roche’s declined option to acquire the ex-US rights to a certain external, early-stage Duchenne development program, as compared to the $89.2 million in collaboration revenue in 2023 related to the amortization of the single, combined performance obligation under the Roche Agreement, which was fully amortized as of December 31, 2023.
For 2025, we recognized $175.5 million in collaboration revenue consisting of (1) $112.0 million related to the expiration of an option for a certain program previously recorded as deferred revenue and (2) $63.5 million related to milestone payments received under the Roche Collaboration Agreement from the regulatory approval of ELEVIDYS in Japan for individuals ages 3- to less than 8-years-old, who do not have any deletions in exon 8 and/or exon 9 in the Duchenne gene and who are negative for anti-AAVrh74 antibodies, as compared to $48.0 million in collaboration revenue in 2024 related to Roche’s declined option to acquire the ex-US rights to a certain external, early-stage Duchenne development program previously recorded as deferred revenue.

The change primarily reflects an increase in net product revenues of ELEVIDYS of $77.9 million in 2025 as a result of its expanded label approval in June 2024, partially offset by higher discounts associated with the PHS chargeback program in 2025 due to ELEVIDYS no longer qualifying for pediatric designation, which had previously reduced our rebate obligations to certain payers. - 78 - The following table summarizes the components of our collaboration and other revenues for the periods indicated: For the Year Ended December 31, 2025 2024 Change Change (in thousands) $ % Collaboration revenue $ 175,500 $ 48,000 $ 127,500 * Contract manufacturing 124,013 49,038 74,975 153 % Royalty revenue 34,428 16,981 17,447 103 % Total collaboration and other $ 333,941 $ 114,019 $ 219,922 193 % *Not meaningful Collaboration and other revenues relate to the Roche Collaboration Agreement.
Investing Activities Cash provided by investing activities for 2024 was $755.6 million, while cash used by investing activities for 2023 was $165.8 million.
Financing Activities Cash used in financing activities was $168.3 million in 2025, compared to $124.8 million of cash provided by financing activities in 2024.
The increase was primarily driven by the following: • $25.2 million increase in professional service expenses primarily related to ongoing litigation matters, our continuing expansion efforts and continuing efforts to commercialize ELEVIDYS; • $14.2 million increase in compensation and other personnel expenses primarily due to changes in headcount; • $10.3 million increase in stock-based compensation expense primarily related to the achievement of performance conditions related to certain PSUs during the year ended December 31, 2024 and changes in headcount; • $6.8 million increase in facility- and technology-related expenses primarily due to our continuing expansion efforts; and • $20.1 million increase in other expenses primarily due to the timing of charitable contribution activity.
This was partially offset by certain performance conditions being met in June and December 2025 for certain PSUs; • $5.0 million increase in facility- and technology-related expenses primarily due to utilization of our Bedford, Massachusetts facility beginning in 2025, with no similar activity in 2024; and • $3.1 million decrease in other expenses primarily due to the timing of charitable contribution activity, partially offset by certain state tax penalties in 2025, with no similar activity in 2024.
