        show associations between HTT lowering and changes in clinical outcome
        measures.
    --  12-month results from the PIVOT-HD Phase 2 study of PTC518 expected in
        Q2 2025.

Fourth Quarter and Full Year 2024 Financial Highlights:

    --  Total revenues were $213.2 million for the fourth quarter of 2024,
        compared to $307.1 million for the fourth quarter of 2023. Total revenue
        was $806.8 million for full year 2024, compared to $937.8 million for
        full year 2023.
    --  Total revenue includes net product revenue across the commercial
        portfolio of $154.7 million for the fourth quarter of 2024 and $601.0
        million for full year 2024, compared to $155.1 million for the fourth
        quarter of 2023 and $661.2 million for full year 2023. Total revenue
        also includes royalty, collaboration, and manufacturing revenue of $58.5
        million in the fourth quarter of 2024 and $205.8 million for full year
        2024, compared to $152.0 million for the fourth quarter of 2023 and
        $276.6 million for full year 2023.
    --  Translarna net product revenues were $93.7 million for the fourth
        quarter of 2024, compared to $75.2 million for the fourth quarter of
        2023. Translarna net product revenues were $339.9 million for full year
        2024, compared to $355.8 million for full year 2023.
    --  Emflaza net product revenues were $50.5 million for the fourth quarter
        of 2024, compared to $67.4 million for the fourth quarter of 2023.
        Emflaza net product revenues were $207.2 million for full year 2024,
        compared to $255.1 million for full year 2023. These results were driven
        by the expiration of Emflaza's orphan drug exclusivity in February 2024.
    --  Roche reported Evrysdi(®) full year 2024 sales of approximately 1,631
        CHF million, resulting in royalty revenue of $203.9 million to PTC for
        full year 2024, as compared to $168.9 million for full year 2023. Also
        in the fourth quarter of 2023, PTC recorded a sales milestone of $100.0
        million for the achievement of $1.5 billion in worldwide annual net
        sales from Evrysdi. This sales milestone was recorded as collaboration
        revenue.
    --  Based on U.S. GAAP (Generally Accepted Accounting Principles), GAAP R&D
        expenses were $124.8 million for the fourth quarter of 2024, compared to
        $121.4 million for the fourth quarter of 2023. GAAP R&D expenses were
        $534.5 million for full year 2024, compared to $666.6 million for full
        year 2023. The slight increase in R&D expense for the fourth quarter of
        2024 reflects additional costs due to manufacturing, regulatory filings,
        and inspections primarily related to Kebilidi and sepiapterin. The
        decrease in R&D expense for full year 2024 relates to decreases in
        program spend related to our strategic portfolio prioritization as we
        continue to focus our resources on our differentiated, high potential
        research and development programs. R&D expense also included a total of
        $65.0 million regulatory success-based milestones paid to the former
        Censa securityholders for the year ended December 31, 2024, as compared
        to a $30.0 million success-based development milestone payable to the
        former Censa securityholders for the year ended December 31, 2023.
    --  Non-GAAP R&D expenses were $116.0 million for the fourth quarter of
        2024, excluding $8.8 million in non-cash, stock-based compensation
        expense, compared to $113.2 million for the fourth quarter of 2023,
        excluding $8.1 million in non-cash, stock-based compensation expense.
        Non-GAAP R&D expenses were $497.9 million for full year 2024, excluding
        $36.6 million in non-cash, stock-based compensation expense, compared to
        $613.6 million for full year 2023, excluding $52.9 million in non- cash,
        stock-based compensation expense.
    --  GAAP SG&A expenses were $84.7 million for the fourth quarter of 2024,
        compared to $76.3 million for the fourth quarter of 2023. GAAP SG&A
        expenses were $300.9 million for full year 2024, compared to $332.5
        million for full year 2023. The increase in SG&A expense for the fourth
        quarter of 2024 reflects our continued investment to support commercial
        activities, including expanding our commercial portfolio. The decrease
        in SG&A expense for full year 2024 was primarily due to lower employee
        costs as a result of the reduction in the workforce in 2023.
    --  Non-GAAP SG&A expenses were $76.3 million for the fourth quarter of
        2024, excluding $8.4 million in non-cash, stock-based compensation
        expense, compared to $67.9 million for the fourth quarter of 2023,
        excluding $8.4 million in non-cash, stock-based compensation expense.
        Non-GAAP SG&A expenses were $262.9 million for full year 2024, excluding
        $38.0 million in non-cash, stock-based compensation expense, compared to
        $283.8 million for full year 2023, excluding $48.7 million in non- cash,
        stock-based compensation expense.
    --  The change in the fair value of deferred and contingent consideration
        was a gain of $10.2 million for the fourth quarter of 2024, compared to
        a gain of $2.7 million for the fourth quarter of 2023. Change in the
        fair value of deferred and contingent consideration was a gain of $4.5
        million for full year 2024, compared to a gain of $127.7 million for
        full year 2023. The full year 2024 change is primarily related to the
        Company's strategic portfolio prioritization and decision to discontinue
        its preclinical and early research programs in its gene therapy platform
        in May 2023, which included programs for FA and Angelman syndrome.
    --  The intangible asset impairment was $159.5 million for the fourth
        quarter and full year 2024, compared to $0.0 million for fourth quarter
        and $217.8 million for the full year 2023, which represented a non-cash
        charge. For the fourth quarter and full year 2024, we impaired $159.5
        million related to a decrease in projected cash flows due to refinements
        in current market assumptions and the timing of patient treatments for
        AADC. For the full year 2023, we fully impaired the FA and Angelman
        syndrome intangible assets and recorded impairment expense of $217.8
        million.
    --  Net loss was $65.9 million for the fourth quarter of 2024, compared to
        net loss of $155.8 million for the fourth quarter of 2023. Net loss was
        $363.3 million for full year 2024, compared to net loss of $626.6
        million for full year 2023.
    --  Cash, cash equivalents, and marketable securities was $1,139.7 million
        on December 31, 2024, compared to $876.7 million on December 31, 2023.
    --  Shares issued and outstanding as of December 31, 2024, were 77,704,188.

PTC's actual results, performance or achievements could differ materially from those expressed or implied by forward-looking statements it makes as a result of a variety of risks and uncertainties, including those related to: the outcome of pricing, coverage and reimbursement negotiations with third party payors for PTC's products or product candidates that PTC commercializes or may commercialize in the future; PTC's ability to maintain its marketing authorization of Translarna for the treatment of nmDMD in Brazil, Russia, the European Economic Area (EEA) and other regions, including whether the European Commission adopts the negative opinion from the Committee for Medicinal Products for Human Use (CHMP) for the conditional marketing authorization for Translarna in the EEA, or PTC's ability to identify other potential mechanisms by which it may provide Translarna to nmDMD patients in the EEA; PTC's ability to use the clinical data from its international drug registry study and real-world evidence concerning Translarna's benefits to support a continued marketing authorization for Translarna for the treatment of nmDMD in the EEA; PTC's ability to use the results of Study 041, a randomized, 18-month, placebo-controlled clinical trial of Translarna for the treatment of nmDMD followed by an 18-month open-label extension, and from its international drug registry study to support a marketing approval for Translarna for the treatment of nmDMD in the United States; whether investigators agree with PTC's interpretation of the results of clinical trials and the totality of clinical data from its trials in Translarna; expectations with respect to PTC's license and collaboration agreement with Novartis Pharmaceuticals Corporation including its right to receive development, regulatory and sales milestones, profit sharing and royalty payments from Novartis; expectations with respect to Upstaza/Kebilidi, including commercialization, manufacturing capabilities, and the potential achievement of sales milestones and contingent payments that PTC may be obligated to make; expectations with respect to sepiapterin, including any regulatory submissions and potential approvals, commercialization, and the potential achievement of regulatory and sales milestones and contingent payments that PTC may be obligated to make; expectations with respect to vatiquinone, including any regulatory submissions and potential approvals, commercialization, and the potential achievement of regulatory and sales milestones and contingent payments that PTC may be obligated to make; expectations with respect to the commercialization of Evrysdi under PTC's SMA collaboration; expectations with respect to the commercialization of Tegsedi and Waylivra; significant business effects, including the effects of industry, market, economic, political or regulatory conditions; changes in tax and other laws, regulations, rates and policies; the eligible patient base and commercial potential of PTC's products and product candidates; PTC's scientific approach and general development progress; PTC's ability to satisfy its obligations under the terms of its lease agreements; the sufficiency of PTC's cash resources and its ability to obtain adequate financing in the future for its foreseeable and unforeseeable operating expenses and capital expenditures; and the factors discussed in the "Risk Factors" section of PTC's most recent Annual Report on Form 10-K, as well as any updates to these risk factors filed from time to time in PTC's other filings with the SEC. You are urged to carefully consider all such factors.

As with any pharmaceutical under development, there are significant risks in the development, regulatory approval and commercialization of new products. There are no guarantees that any product will receive or maintain regulatory approval in any territory, or prove to be commercially successful, including Translarna, Emflaza, Upstaza, Kebilidi, Evrysdi, Tegsedi, Waylivra, sepiapterin or vatiquinone.
