Adaptive Biotechnologies Corp 8-K

What Happened

• On December 30, 2025, Adaptive Biotechnologies Corporation (ADPT) announced that its 70%‑owned subsidiary, Digital Biotechnologies, Inc., held an initial closing of a Series A Preferred Stock financing. The financing round is expected to bring total proceeds of up to $15 million. Adaptive expects that, upon completion of the Series A round, it will retain a nearly 50% ownership interest in Digital Biotechnologies and will continue to consolidate Digital Biotechnologies’ results in its financial statements.

Key Details

• Filing date: December 30, 2025 (Form 8‑K, Item 8.01 — Other Events).
• Subsidiary: Digital Biotechnologies, Inc. (70% owned prior to the full Series A close).
• Financing size: Total anticipated proceeds up to $15 million (Series A Preferred Stock).
• Ownership impact: Adaptive expects to hold a nearly 50% stake after the round and to continue consolidating Digital Biotechnologies’ financial results.

Why It Matters

• This transaction affects Adaptive’s ownership percentage in a partly owned subsidiary and could change how investors view the company’s exposure to an early‑stage business. Adaptive will continue to consolidate Digital Biotechnologies in its financial statements, meaning the subsidiary’s assets, liabilities and results will still appear on Adaptive’s consolidated financials. The filing also highlights that Digital Biotechnologies is an early‑stage company with no revenues to date and includes forward‑looking statements and associated risks, so outcomes (final proceeds and ownership percentages) are not guaranteed.
