CRBU Furnishes Press Release Reporting Q2 2025 Results (Exhibit 99.1)

Rhea-AI Filing Summary

Caribou Biosciences, Inc. furnished a press release announcing its financial results for the quarter ended June 30, 2025 and provided a business update. The press release is attached as Exhibit 99.1 to this Current Report and is incorporated by reference into the disclosure.

The filing specifies that the Item 2.02 information (including Exhibit 99.1) is being furnished and therefore is not deemed "filed" under the Exchange Act, meaning it is provided for investor information without extending Section 18 liabilities. The 8-K itself does not include separate financial tables or statements beyond the furnished press release.

Insights

Financial Analyst

TL;DR: Routine earnings press release furnished; neutral market impact without disclosed financial details in the 8-K.

The company furnished a press release reporting results for the quarter ended June 30, 2025. Because the release is explicitly described as "furnished" rather than "filed," the disclosure follows common practice for distributing quarterly results while limiting Section 18 liability. The 8-K does not itself present financial tables or metrics, so investors must read Exhibit 99.1 for the actual figures. In isolation, this filing is informational and not materially transformative.

Corporate Governance Expert

TL;DR: Furnishing the press release is standard governance practice to inform stakeholders while limiting legal exposure.

The disclosure emphasizes that Item 2.02 content and Exhibit 99.1 are furnished, not filed, which preserves the company’s objective of communicating results without expanding Exchange Act liability. The filing identifies Exhibit 99.1 as the press release and includes the interactive data cover page as Exhibit 104. From a governance perspective this is a routine, compliant approach to releasing quarterly results.
