The presentation will be webcast live on the Events and Presentations page under the Investors section of PTC Therapeutics' website at https://ir.ptcbio.com/events-presentations and will be archived for 30 days following the presentation.

​

“I am very proud of our team’s performance across every part of the company in 2024,” Dr. Klein said. “We met every one of our planned clinical and regulatory milestones on schedule. Commercially, we outperformed guidance. And we begin 2025 with a strong cash balance, ready to build on our successes. PTC, now stronger and more innovative than ever, will continue to work to bring transformative therapies to the patient communities we serve in 2025 and beyond.”

​

Key 2024 Corporate Highlights:

| ● | Unaudited net product revenue of approximately $814 million, exceeding guidance.

| o | Strong performance was driven by in-line products, including the DMD franchise with unaudited net product revenue of approximately $340 million for Translarna™ (ataluren) and approximately $207 million for Emflaza® (deflazacort) in 2024.

​

| ● | Cash balance of approximately $1.1 billion as of December 31, 2024, with an additional $1.0 billion in upfront proceeds from PTC518 collaboration agreement with Novartis following closing.

​

| ● | PTC submitted four regulatory approval applications to FDA:

| o | Kebilidi™ (eladocagene exuparvovec-tneq) gene therapy for AADC deficiency, approved in November 2024.

| o | Sepiapterin for children and adults with PKU, accepted with an FDA action date of July 29, 2025.

| o | Vatiquinone for children and adults with FA, with filing acceptance decision anticipated Q1 2025.

| o | Translarna for nmDMD, accepted with no action date provided.

​

| ● | PTC signed a global license and collaboration agreement with Novartis for the research, development and commercialization of PTC518 for HD, which has now closed. Key aspects of the transaction include the following:

| o | PTC to receive $1.0 billion in upfront proceeds following closing.

| o | PTC is eligible to receive up to $1.9 billion in development, regulatory and sales milestones.

​

​

| o | PTC to receive 40% profit share on U.S. sales, and double-digit tiered royalties on ex-U.S. sales.

| ● | PTC received $150 million from the sale of the Rare Pediatric Disease PRV it received with FDA approval of Kebilidi.

| ● | In December 2024, PTC had a Type C meeting with FDA to discuss the potential for HTT lowering to serve as a surrogate endpoint to support accelerated approval for PTC518 for HD. The Agency was aligned with the scientific rationale for HTT lowering as a potential surrogate endpoint and asked that PTC provide additional clinical data, such as those being collected in PIVOT-HD, to show associations between HTT lowering and changes in clinical outcome measures.
