Rhea-AI Filing Summary

Rapid Micro Biosystems secured a multi-tranche term loan facility of up to $45.0 million, drawing $20.0 million at closing. The facility is structured in four tranches with additional amounts available when commercial and operational milestones are met and includes a lender option tranche of $5.0 million. Loans are secured by a first-priority lien on substantially all assets of the company and may be guaranteed by subsidiaries.

Interest is floating with an initial rate of 11.5% per annum (floor 11.0%), a 36-month interest-only period followed by amortization, and a maturity date of September 1, 2030. Fees include a 1.0% commitment fee on amounts drawn, prepayment premiums (3.0% year one, 2.0 year two, 1.0% thereafter), and a 4.0% end-of-term payment on amounts drawn. Each draw requires issuance of warrants equal to 3.0% of the drawn amount (cashless exercise, ten-year term); the company issued warrants for up to 179,104 shares at a $3.35 exercise price for the first tranche. The agreement contains customary covenants and defaults but does not require maintaining specific revenue or cash thresholds.

Rapid Micro Biosystems ha ottenuto una linea di credito a termine a più tranche fino a $45,0 milioni, prelevando $20,0 milioni al closing. La struttura prevede quattro tranche, con somme aggiuntive disponibili al raggiungimento di milestone commerciali e operative, e include una tranche opzionale per il creditore di $5,0 milioni. I prestiti sono garantiti da un privilegio di primo grado sulla quasi totalità degli asset della società e possono essere garantiti dalle controllate.

Il tasso è variabile con un tasso iniziale del 11,5% annuo (floor 11,0%), un periodo di 36 mesi di sola corresponsione degli interessi seguito da ammortamento, e scadenza il 1° settembre 2030. Le commissioni includono un 1,0% di commitment fee sugli importi erogati, penali di estinzione anticipata (3,0% primo anno, 2,0% secondo anno, 1,0% successivamente) e un 4,0% di pagamento a fine termine sugli importi erogati. Ogni erogazione richiede l'emissione di warrant pari al 3,0% dell'ammontare erogato (esercizio cashless, durata dieci anni); la società ha emesso warrant fino a 179.104 azioni a un prezzo di esercizio di $3,35 per la prima tranche. L'accordo contiene covenant e eventi di default usuali ma non impone il mantenimento di specifici livelli di ricavi o disponibilità di cassa.

El interés es variable con una tasa inicial del 11.5% anual (suelo 11.0%), un periodo de 36 meses de solo intereses seguido de amortización, y vencimiento el 1 de septiembre de 2030.

El acuerdo contiene convenios y eventos de incumplimiento habituales pero no exige mantener niveles específicos de ingresos o liquidez.

Rapid Micro Biosystems hat eine mehrstufige Termingeldfazilität in Höhe von bis zu $45,0 Millionen gesichert und dabei bei Closing $20,0 Millionen in Anspruch genommen. Die Fazilität ist in vier Tranchen strukturiert, mit zusätzlichen Beträgen, die bei Erreichen kommerzieller und operativer Meilensteine verfügbar werden, und umfasst eine Options-Tranche des Kreditgebers in Höhe von $5,0 Millionen. Die Darlehen sind durch eine vorrangige Sicherung auf nahezu sämtliches Gesellschaftsvermögen besichert und können von Tochtergesellschaften garantiert werden.

Der Zinssatz ist variabel mit einem Anfangssatz von 11,5% p.a. (Mindestsatz 11,0%), einer 36-monatigen Zinszahlungsphase ohne Tilgung, gefolgt von Amortisation, und einer Fälligkeit am 1. September 2030. Gebühren umfassen eine 1,0% Commitment-Gebühr auf in Anspruch genommene Beträge, Vorfälligkeitsentschädigungen (3,0% im ersten Jahr, 2,0% im zweiten, danach 1,0%) und eine 4,0% End-of-Term-Zahlung auf die in Anspruch genommenen Beträge. Jede Auszahlung erfordert die Ausgabe von Warrants in Höhe von 3,0% des ausgezahlten Betrags (cashless Exercise, Laufzeit zehn Jahre); das Unternehmen gab für die erste Tranche Warrants auf bis zu 179.104 Aktien zu einem Ausübungspreis von $3,35 aus. Die Vereinbarung enthält übliche Covenants und Events of Default, verlangt jedoch nicht das Einhalten bestimmter Umsatz- oder Liquiditätsschwellen.

Positive
  • Immediate liquidity: $20.0 million drawn at closing from a facility totaling $45.0 million
  • Staged tranches tied to milestones provide conditional access to additional capital up to $45.0 million
  • Interest-only period for the first 36 months reduces near-term cash outflows and eases short-term liquidity pressure
  • Secured facility with lender protections that may allow the company to obtain financing that might otherwise be unavailable
Negative
  • High cost of capital: initial interest rate 11.5% with an effective floor of 11.0%, plus fees and a 4.0% end-of-term payment
  • Equity dilution: warrants equal to 3.0% of each draw (first tranche warrants for up to 179,104 shares at $3.35)
  • Secured on substantially all assets, limiting financial flexibility and exposing core assets to lender claims
  • Prepayment penalties (3.0% within first year, 2.0% within year two, 1.0% thereafter) and milestone-based tranche availability create execution risk

Insights

TL;DR: Provides near-term liquidity but at a relatively high cost and with asset-based security and dilution from warrants.

The facility immediately supplies $20.0 million while offering conditional access to up to $45.0 million, which materially extends the company’s financing runway. The interest structure (initial 11.5%, floor 11.0%) and multiple fees (commitment fee, prepayment premiums, 4.0% end-of-term payment) indicate a high all-in cost of capital. Security over substantially all assets and customary default mechanics increase creditor protections and restrict flexibility. Warrants tied to draws create dilution; operational milestone conditions for tranche availability add execution risk for additional funding. Overall, credit terms are tight but typical for growth companies needing near-term capital.

TL;DR: The agreement is a material financing that strengthens liquidity but carries significant cost and equity dilution elements.

The structure balances immediate funding with milestone-based expansion of capacity, preserving optionality for management to access further tranches. The 36-month interest-only period eases near-term cash pressure, though extensions reduce subsequent amortization time. The warrant feature (3.0% of drawn amount; ten-year term) and the issued 179,104 warrants at $3.35 are meaningful dilution components for equity holders. Prepayment penalties and the 4.0% end-of-term fee increase long-term expense. For stakeholders, the facility is impactful for operations but will affect capital structure and cost of capital.

Item 1.01
Entry into a Material Definitive Agreement.
On August 8, 2025 (the “Closing Date”), Rapid Micro Biosystems, Inc. (the "Company") entered into a Loan and Security Agreement (the “LSA”) with the lenders party thereto (the “Lenders”) and Trinity Capital Inc., as administrative agent and collateral agent (the “Agent”).

Under the LSA, the Lenders agreed to extend debt capital to the Company, in the form of a term loan, in tranches totaling an aggregate principal amount of up to $45.0 million available as follows: (a) at closing, an aggregate principal amount of $20.0 million (the “First Tranche”), (b) until January 31, 2027, subject to the achievement of certain commercial and operational milestones, an aggregate principal amount of $10.0 million (the “Second Tranche”), (c) until July 31, 2027, subject to the achievement of certain commercial and operational milestones, an aggregate principal amount of $10.0 million (the “Third Tranche”), and (d) an aggregate principal amount of $5.0 million in Lenders’ sole discretion (the “Fourth Tranche” and collectively with the First Tranche, the Second Tranche and the Third Tranche, the “Tranches”). The obligations of the Lenders to extend such debt capital are subject to certain conditions precedent described in the LSA. The Company is required to pay a commitment fee of 1.0% of the amount drawn, plus related documentation and funding fees, in connection with each drawdown. On (the Closing Date, the Company drew down the First Tranche. The Company’s obligations under the facility may be guaranteed by certain subsidiaries and are secured by a first priority security interest in substantially all assets of the Company and any subsidiaries providing a guarantee.

In connection with the drawdown of any Tranche, the Company is required to issue to the Lenders a warrant to purchase shares of the Company’s Class A common stock (the “Common Stock”). The exercise price (“Exercise Price”) for each warrant shall be equal to the lower of (a) the volume-weighted average price of the Common Stock over the ten days prior to the drawdown, and (b) the closing price of the Common Stock on the day immediately prior to the drawdown. The number of shares of Common Stock for which each warrant is exercisable is equal to 3.0% of the drawn down amount of the applicable Tranche, divided by the Exercise Price. Each warrant shall have a term of ten years from the date of issuance and shall permit cashless exercise, all in accordance with its terms. In connection with the drawdown of the First Tranche, for no additional consideration, the Company issued warrants to purchase up to an aggregate of 179,104 shares of Common Stock, with an Exercise Price of $3.35 per share. Such warrants were issued in a placement transaction exempt from registration under the Securities Act of 1933, as amended, pursuant to Section 4(a)(2) thereof and/or Rule 506 of Regulation D promulgated thereunder.

All Tranches will mature on September 1, 2030 (the “Maturity Date”), unless earlier accelerated under the terms of the LSA. At maturity, the Company is required to repay the then-outstanding principal amount, together with any accrued and unpaid interest thereon and any other obligations outstanding under the LSA. In addition, at maturity or early termination of the LSA, including acceleration of the loans, the Company is required to pay the Lenders an additional 4.0% of the amounts drawn down by the Company under the LSA (the "End of Term Payment").

Interest accrues on the Tranches that the Company has drawn down at a floating rate per annum, calculated based on a 360-day year, equal to the greater of (a) the sum of (i) The Wall Street Journal Prime Rate and (ii) 4.0%, and (b) 11.0%. The initial interest rate is 11.5% per annum. For the first 36 months after the Closing Date (the “Interest Only Period”), the Company is required to make only monthly payments of interest in arrears. Following such period, and until the Maturity Date (the “Amortization Period”), the Company is required to make monthly payments of principal and interest in an amount that fully amortizes the outstanding principal balance due over the duration of the Amortization Period. If the Second Tranche is fully drawn down by the Company, the Interest Only Period will be extended by six months. If the Third Tranche is fully drawn down by the Company, the Interest Only Period will be extended by a further six months. In the event of such extensions of the Interest Only Period, the duration of the Amortization Period will decrease by the same amount. In any event, the total term of all Tranches shall not exceed 60 months.

The Company may voluntarily prepay the outstanding loan balance at any time, in whole or in part, subject to the payment of prepayment premiums. If prepayment occurs on or before the first anniversary of the Closing Date, the premium shall equal 3.0% of the principal being repaid. Thereafter, if prepayment occurs on or before the second anniversary of the Closing Date, the premium shall equal 2.0% of the principal being repaid. Thereafter, the premium shall equal 1.0% of the principal being repaid. For the avoidance of doubt, such prepayment premiums are in addition to the End of Term Payment. Additionally, the Company is required to prepay the outstanding loan balance (plus accrued and unpaid interest thereon, any prepayment premiums and any other obligations that are due and payable) upon a sale, divestment or transfer of all or substantially all assets of the Company and its subsidiaries, taken as a whole, or of a material business line of the Company, the acquisition by a person or group of a sufficient number of the Company’s equity securities to elect a majority of the members of the Company’s board of directors, or the acceleration of the loans by the Agent on behalf of the Lenders following an event of default under the LSA.

The LSA contains customary affirmative and negative covenants, including with respect to notice obligations, limitations on new indebtedness, liens, investments and transactions with affiliates of the Company, restrictions on the



payment of dividends, maintenance of collateral and accounts and maintenance of insurance. The LSA does not contain any covenants to maintain a specified level of revenues or cash resources.

The LSA contains customary representations and warranties of the Company, as well as customary events of default, the occurrence of which may accelerate the obligations of the Company, increase the interest rate by a specified default rate and impose other consequences described in the LSA. Such events include among others, failure to make payments when due, breach of covenants, insolvency, a cross-default to other indebtedness, a judgment event of default, the occurrence of a material adverse change to the Company,and delisting of the Company’s securities from Nasdaq.

The foregoing description of the LSA does not purport to be complete and is qualified in its entirety by reference to the full text of the LSA, which will filed as an exhibit to the Company's Quarterly Report on Form 10-Q for the period ended June 30, 2025 and is incorporated herein by reference.
