Emflaza net product revenues were $218.3 million for the full year 2022, compared to $187.3 million for the full year 2021. These results reflect new patient prescriptions, high compliance, and fewer discontinuations.

&nbsp;&nbsp;&nbsp;&nbsp;● Roche reported Evrysdi 2022 year to date sales of approximately CHF 1,119 million, resulting in full year 2022 royalty revenue of $113.5 million to PTC, as compared to $54.6 million for full year 2021.

&nbsp;&nbsp;&nbsp;&nbsp;● Based on U.S. GAAP (Generally Accepted Accounting Principles), GAAP R&D expenses were $188.7 million for the fourth quarter of 2022, compared to $149.8 million for the fourth quarter of 2021. GAAP R&D expenses were $651.5 million for the full year 2022, compared to $540.7 million for the full year 2021. The increase reflects additional investment in research programs and advancement of the clinical pipeline.

&nbsp;&nbsp;&nbsp;&nbsp;● Intangible asset impairment was $33.4 million for the fourth quarter and full year 2022, which represents a non-cash charge. The partial impairment was related to a decrease in projected cash flows due to refinements in current market assumptions and the timing of patient treatments.

&nbsp;&nbsp;&nbsp;&nbsp;● Change in the fair value of deferred and contingent consideration was a loss of $6.3 million for the fourth quarter of 2022, compared to a gain of $12.1 million for the fourth quarter of 2021. Change in the fair value of deferred and contingent consideration was a gain of $25.9 million for the full year 2022, compared to a gain of $0.5 million for the full year 2021.

**Non-GAAP Financial Measures:**

In this press release, the financial results of PTC are provided in accordance with GAAP and using certain non-GAAP financial measures. In particular, the non-GAAP R&D and SG&A expense financial measures exclude non-cash, stock-based compensation expense, and the revenue and percentage changes in revenue growth at CER are presented excluding the impact of changes in foreign currency exchange rates. For financial measures given at CER, the current period's foreign currency revenue values are converted into U.S. dollars using the average exchange rates from the prior period. These non-GAAP financial measures are provided as a complement to financial measures reported in GAAP because management uses these non-GAAP financial measures when assessing and identifying operational trends. In management's opinion, these non-GAAP financial measures are useful to investors and other users of PTC's financial statements by providing greater transparency into the historical and projected operating performance of PTC and the company's future outlook. Non-GAAP financial measures are not an alternative for financial measures prepared in accordance with GAAP. Quantitative reconciliations of the non-GAAP financial measures to their respective closest equivalent GAAP financial measures are included in the table below.
