Zymeworks Inc. Material Event - Acquisition of Theravance Biopharma

Zymeworks Inc., a company developing multifunctional cancer treatments, has agreed to acquire Theravance Biopharma, Inc. This move represents a significant shift in the company’s growth strategy and financial structure.

1. What happened?

Zymeworks has signed a definitive agreement to acquire Theravance Biopharma. By bringing Theravance into the fold, Zymeworks is looking to integrate Theravance’s research pipeline with its own proprietary Azymetric™ and EFECT™ platforms.

2. How is Zymeworks paying for it?

Zymeworks is funding this acquisition through a combination of existing cash and new debt. Specifically, they have secured $350 million in loans from OMERS Life Sciences via senior secured notes.

• What this means for you: Taking on $350 million in "senior secured" debt changes the company's risk profile. Because these lenders get paid first in the event of financial trouble, Zymeworks now has a fixed interest obligation that will impact their cash flow. You should watch how this debt affects their ability to fund ongoing research.

3. The Deal Structure: Cash and CVRs

Theravance shareholders will receive $17.00 in cash per share, plus a non-tradable Contingent Value Right (CVR).

• What’s a CVR? Think of this as a "bonus" payment. It’s a promise of extra cash for Theravance shareholders if the new drugs hit specific clinical or regulatory milestones. For Zymeworks, this is a smart way to lower the upfront cost of the deal while aligning the final price with the actual success of the research.

4. Why does this matter for investors?

Zymeworks is transitioning from a platform-focused company to a larger, more complex pharmaceutical business.

• Increased Burn Rate: Expect Zymeworks to spend cash more aggressively in the near term as they integrate two research teams and manage new interest payments.
• The "Bet": The success of this investment hinges on whether the combined pipeline can produce profitable cancer treatments faster than the companies could have on their own.

5. Who is affected?

• Zymeworks Shareholders: You are now invested in a larger, more leveraged entity. The potential for growth is higher, but so is the financial risk.
• Theravance Shareholders: You are effectively cashing out at $17.00 per share, with a potential upside tied to the CVR.

6. What happens next?

The deal is expected to close in the second half of 2026, pending regulatory approval and a vote from Theravance shareholders.

• The "End Date": If the deal isn't finalized by December 28, 2026, either company can walk away.
• The "Break-up Fee": If the deal falls through under specific conditions, Theravance is required to pay Zymeworks a $32.5 million fee. This acts as a safeguard for Zymeworks, ensuring that the time and resources spent on this deal aren't wasted without some compensation.

Investor Checklist: Is this right for you?

Before making a decision, consider these three questions:

1. Risk Tolerance: Are you comfortable with the increased debt load Zymeworks is taking on to fund this growth?
2. Timeline: Are you prepared to wait until late 2026 for the deal to close and potentially longer for the research pipeline to yield results?
3. Pipeline Confidence: Do you believe the combined research teams can hit the milestones required to make the CVRs valuable and the acquisition profitable?
