Boundless Bio, Inc. 8-K

What Happened
On May 8, 2026, Boundless Bio, Inc. (NASDAQ: BOLD) announced its financial results for the quarter ended March 31, 2026 by issuing a press release, which the company furnished as Exhibit 99.1 to a Form 8-K (Item 2.02). The Form 8-K states the release is furnished under General Instruction B.2 of Form 8-K and therefore is not deemed “filed” for purposes of Section 18 of the Exchange Act.

Key Details

• Filing date: May 8, 2026 (Form 8-K).
• Reporting period: quarter ended March 31, 2026.
• Exhibit included: 99.1 (press release) and Exhibit 104 (Inline XBRL cover page).
• Legal note: information furnished (not “filed”) per General Instruction B.2; signed by Jessica Oien, Chief Legal Officer and Corporate Secretary.

Why It Matters
A furnished earnings release gives investors the company’s latest quarterly results and operational snapshot (earnings, revenue, and other metrics). Because the Form 8-K only furnishes the press release, investors should review Exhibit 99.1 for the detailed numbers and any management commentary, and consult the company’s other SEC filings for full financial statements and context. The “furnished, not filed” designation affects certain legal liabilities under the Exchange Act and is standard language for press-release disclosures.
