Rhea-AI Filing Summary

RA Capital Management and its affiliates filed an amended Schedule 13D showing they no longer beneficially own any shares of Cidara Therapeutics, Inc. Each reporting person now reports 0.00 shares and 0.0% of Cidara’s common stock, with no sole or shared voting or dispositive power. The amendment explains that a tender offer for Cidara’s shares expired on January 6, 2026, after which the buyer accepted all validly tendered shares and then completed a merger on January 7, 2026.

Following the merger, Cidara became a wholly owned subsidiary of the acquiror, its common stock was deregistered under the Exchange Act, and it ceased trading on the Nasdaq Stock Market. RA Capital’s fund had tendered all of its common and Series A shares, and its pre-funded warrants were cashlessly exercised and converted into the right to receive the cash offer price, leaving the reporting persons with no remaining beneficial ownership.

Insights

RA Capital exits Cidara after a completed tender offer and merger.

The document shows that RA Capital Management, its healthcare fund, and principals Peter Kolchinsky and Rajeev Shah now report 0.00 shares and 0.0% of Cidara Therapeutics common stock. This follows a tender offer that expired on January 6, 2026, after which all validly tendered shares were accepted for payment and a merger was completed, taking Cidara private.

At the effective time of the merger, all remaining common and Series A preferred shares (other than specified excluded categories) were cancelled and converted into the right to receive the respective cash offer prices. Options became fully vested and were either cashed out or cancelled if out of the money, and pre-funded warrants held by the fund were cashlessly exercised into common shares that were then converted into the cash merger consideration.

As a result, Cidara’s common stock was deregistered under the Exchange Act and delisted from Nasdaq, eliminating its public float. The filing also notes that the reporting persons ceased to be beneficial owners of more than five percent of Cidara’s common shares on January 7, 2025, and it formalizes their lack of ongoing equity stake or voting power after the transaction.
