• Roche reported Evrysdi 2020 year-to-date sales of approximately CHF 55 million.

Additionally, in October 2020, Chugai Pharmaceutical, Co. Ltd, a member of the Roche group, announced that a new drug application for Evrysdi for the treatment of SMA was filed in Japan. The filing in Japan triggered a $7.5 million milestone payment to PTC in the fourth quarter of 2020. As a result, PTC recognized $35.0 million in the third quarter of 2020 and $7.5 million in the fourth quarter of 2020 of collaboration revenue associated with Roche milestone events.

GAAP R&D expenses were $477.6 million for the full year 2020, compared to $257.4 million for the full year 2019. The increase in R&D expenses for the fourth quarter and full year 2020 reflects costs associated with advancing the gene therapy and Bio-e platforms, increased investment in research programs, and advancement of the clinical pipeline. Additionally, the increase in R&D expenses full year 2020 includes one-time charges in 2020 of $53.6 million related to the acquisition of Censa Pharmaceuticals, and $41.4 million related to the MassBiologics of the University of Massachusetts Medical School agreement for commercial manufacturing of our lead gene therapy program in AADC deficiency.
• Non-GAAP R&D expenses were $105.3 million for the fourth quarter of 2020, excluding $12.7 million in non-cash, stock-based compensation expense, compared to $76.2 million for the fourth quarter of 2019, excluding $5.6 million in non-cash, stock-based compensation expense.

GAAP SG&A expenses were $245.2 million for the full year 2020, compared to $202.5 million for the full year 2019.

• Non-GAAP SG&A expenses were $66.8 million for the fourth quarter of 2020, excluding $8.7 million in non-cash, stock-based compensation expense, compared to $57.7 million for the fourth quarter of 2019, excluding $5.8 million in non-cash, stock-based compensation expense.

• Change in the fair value of deferred and contingent consideration was $6.3 million for the fourth quarter of 2020, compared to $12.4 million for the fourth quarter of 2019. Change in the fair value of deferred and contingent consideration was $23.3 million for the full year 2020, compared to $48.4 million for the full year 2019. The change is related to the fair valuation of the potential future consideration to be paid to former equity holders of Agilis Biotherapeutics, Inc. (Agilis), as a result of our merger with Agilis which closed in August 2018. Changes in the fair value were due to the re-calculation of discounted cash flows for the passage of time and changes to certain other estimated assumptions.
• Settlement of deferred and contingent consideration was $10.6 million for the full year 2020. The settlement of deferred and contingent consideration is related to a loss upon the settlement of the deferred and contingent consideration liabilities as a result of the rights exchange agreement with certain former shareholders of Agilis, whereby such former shareholders exchanged their pro rata share of specific future cash milestone payments in the aggregate amount of $225 million for a mixture of cash and equity of PTC. Under this agreement, which the former shareholders and PTC entered into on April 29, 2020, PTC has paid $36.9 million in cash and issued 2,821,176 shares of common stock in exchange for the cancellation and forfeiture of the participating shareholders' rights to receive (i) $174.0 million, in the aggregate, of potential milestone payments based on the achievement of certain regulatory milestones and (ii) $37.6 million, in the aggregate, of $40.0 million in development milestone payments that would have been due upon the passing of the second anniversary of the closing of PTC's merger with Agilis, regardless of whether the milestones are achieved.
• Net loss was $74.4 million for the fourth quarter of 2020, compared to net loss of $77.7 million for the fourth quarter of 2019. Net loss was $438.2 million for the full year 2020, compared to net loss of $251.6 million for the full year 2019.
• Cash, cash equivalents, and marketable securities was $1.1 billion at December 31, 2020, compared to $686.6 million at December 31, 2019.
• Shares issued and outstanding as of December 31, 2020 were 69,718,096.
