ADAR1 Announces ISS Recommends Keros Therapeutics Stockholders WITHHOLD Votes from Directors Dr. Mary Ann Gray and Dr. Alpna Seth

ADAR1 Urges Board to Release Strategic Review Results Before, Not After, Annual Meeting

AUSTIN, Texas, May 21, 2025 /PRNewswire/ -- ADAR1 Capital Management, LLC (together with its affiliates, "ADAR1" or "We"), the largest stockholder of Keros Therapeutics (Nasdaq: KROS) ("Keros" or the "Company") with approximately 13.3% of the Company's outstanding shares, today announced that leading independent proxy advisory firm Institutional Shareholder Services Inc. ("ISS") has recommended that Keros stockholders WITHHOLD votes from incumbent directors Dr. Mary Ann Gray and Dr. Alpna Seth at the Company's upcoming Annual Meeting of Stockholders (the "Annual Meeting"), scheduled for June 4, 2025.

In its report, ISS raised serious concerns regarding the Company's governance and concluded that greater accountability at Keros is needed.

"We are pleased that ISS has recognized the need for improved governance and oversight at Keros," said Dr. Daniel Schneeberger, Managing Partner of ADAR1. "We believe this recommendation validates the concerns we have raised regarding the Company's Board and supports our view that stockholders would benefit from fresh, independent directors."

ADAR1 also noted that the Company announced that it intends to disclose the outcome of its strategic review process five days after the Annual Meeting. Stockholders are being asked to cast critical votes without knowing whether the Board's strategic process has produced a result that is in the best interests of stockholders. ADAR1 calls on the Company to disclose the results of its strategic review before the Annual Meeting so that stockholders can evaluate whether the outcome is satisfactory before deciding how to vote.

Dr. Schneeberger continued, "In our view, the Company's cash balance is grossly excessive relative to its clinical opportunities and any credible strategic use. There is no reason this Board cannot commit to a significant return of capital now. Its decision to delay announcing a plan until after the annual meeting raises additional concerns about the Board's stewardship and reinforces the need for accountability."

Stockholders can review ADAR1's investor presentation outlining the rationale for why ADAR1 is withholding support from Dr. Gray and Dr. Seth, which is available here.
