Rapid Micro Biosystems Raises $8.9M Net in Underwritten Offering, Adds $140K D&O Purchase

Rapid Micro Biosystems executed two capital-raising transactions: an underwritten offering expected to deliver approximately $8.9 million in net proceeds, and a concurrent registered direct purchase by certain directors and officers for about $140,000. The underwritten deal includes 3,581,000 shares paired with Series A and Series B warrants, plus up to 1,463,000 pre-funded warrants with accompanying warrants, priced at $1.955 per share unit and $1.945 per pre-funded unit. The concurrent insider purchase mirrors the warrant terms and is contingent on the closing of the underwritten offering, both expected to close on or about May 20, 2026. Proceeds will fund working capital and general corporate purposes.Agreement 1: Rapid Micro Biosystems Prices Underwritten Equity and Warrant Offering for $8.9M NetAgreement type: Underwriting Agreement for underwritten equity and warrant offeringCounterparty: TD Securities (USA) and Lake Street Capital Markets, as representatives of the underwritersSigned / Effective: May 18 2026 / May 18 2026Duration / Termination: At willReason: Raise capital for working capital and corporate purposesAgreement 2: Rapid Micro Biosystems Adds $140K Director Purchase in Concurrent Registered OfferingAgreement type: Securities Purchase Agreement for registered direct equity and warrant purchaseCounterparty: Certain directors and officers of Rapid Micro BiosystemsSigned / Effective: May 18 2026 / May 18 2026Duration / Termination: At willReason: Supplement capital alongside the underwritten raiseOriginal SEC Filing: RAPID MICRO BIOSYSTEMS, INC.
