Curis (CRIS) investor relations material

Executive summary

• A special meeting will be held virtually on June 25, 2026, to vote on a reverse stock split and a potential adjournment proposal.

• The reverse stock split would combine issued shares at a ratio between 1-for-5 and 1-for-25, as determined by the board within six months of approval.

• The primary goal is to increase the share price to meet Nasdaq listing requirements and avoid delisting.

• The board recommends voting in favor of both proposals.

Voting matters and shareholder proposals

• Proposal 1 seeks approval for amendments to effect a reverse stock split at a ratio between 1-for-5 and 1-for-25, with the board having discretion on timing and ratio.

• Proposal 2 allows adjournment of the meeting to solicit more proxies if needed for Proposal 1.

• Only these two proposals will be considered at the meeting; no other business will be transacted.

• Each share entitles the holder to one vote; a majority of votes cast is required for approval.

• Stockholder proposals for the 2027 annual meeting must be submitted by December 22, 2026, for inclusion in the proxy statement.

Board of directors and corporate governance

• The board retains authority to abandon the reverse stock split even after stockholder approval if deemed not in the best interest of the company.

• The board will determine the exact ratio and timing of the reverse split and will publicly announce the decision.
