Analysis
PTC reported second-quarter total revenues of $ 360,519, compared with $ 178,875 in the second quarter of 2025.

Sephience was the principal commercial growth driver. Sephience net product revenues were $151.3 million and increased 21% compared with the first quarter of 2026, with 1,647 patients on commercial therapy worldwide as of June 30, 2026. The company cited continued broad uptake and geographical expansion, with most revenue from the US and increasing international contributions. This growth offset lower revenue from Translarna, at $42.2 million versus $59.5 million, and Emflaza, at $24.6 million versus $36.4 million amid continued generic erosion.
The revenue increase and lower operating costs moved the company to profitability. Income from operations was 148,977, compared with a loss from operations of (34,957), and net income attributable to common stockholders was $ 83,496 versus a loss of $ (64,849). GAAP R&D was $ 99,150 versus $ 112,990 and GAAP SG&A was $ 80,630 versus $ 85,262. Interest expense, net was (48,481), compared with (30,358), and total debt was $ 590,970 at June 30, 2026.
Liquidity was $ 2,229,082 of cash, cash equivalents and marketable securities at June 30, 2026. During June, PTC issued $550.0 million of 0% senior convertible notes due in 2031 and repurchased the majority of its 1.5% senior convertible notes due in September 2026. Full-year 2026 total revenue guidance was increased to $1.18 to $1.28 billion, product revenue guidance was raised to $850 to $950 million, and GAAP R&D and SG&A expense guidance remained $775 to $815 million.
Pipeline execution remains a key operating focus. PTC reported positive PIVOT-HD long-term extension results, ongoing enrollment in Novartis-funded INVEST-HD, an expected Q3 2026 initiation for the vatiquinone PROVE-FA study, initiation of the PTC612 Phase 1 study in Q2 2026, and an expected Q3 2026 initiation for the PTC844 Phase 2a study. The company also named PTC303 as its MSH3 splicing program development candidate, with a plan to enter the clinic in 2027.
