IMPINJ INC 8-K

What Happened
Impinj, Inc. announced on January 13, 2026 that it released preliminary unaudited financial information for the fourth quarter ended December 31, 2025. The company issued a press release titled “Impinj Announces Preliminary Fourth-Quarter 2025 Revenue and Adjusted EBITDA Ahead of Participation at 28th Annual Needham Growth Conference,” which is attached as Exhibit 99.1 to the Form 8‑K.

Key Details

• Filing date: January 13, 2026; quarter covered: Q4 ended December 31, 2025.
• The filing includes a press release with preliminary, unaudited Q4 2025 revenue and adjusted EBITDA information (Exhibit 99.1).
• Impinj stated actual Q4 results are still being finalized and that preliminary figures are subject to further review and could differ materially from final results.
• The company noted the 8‑K information and attached release are not deemed “filed” for purposes of Section 18 of the Exchange Act and are not incorporated by reference into other filings.

Why It Matters
Preliminary Q4 revenue and adjusted EBITDA give investors an early look at Impinj’s quarterly performance ahead of formal, audited results and the company’s participation at the Needham Growth Conference. However, because the numbers are unaudited and management warned they may change materially, investors should treat this as preliminary information and await the company’s finalized reported results and any subsequent 10‑Q/10‑K filings for definitive figures.
