Pratteln, Switzerland, June 18, 2024 - Santhera Pharmaceuticals (SIX: SANN) announces that it has entered into committed financing arrangements that, when consummated, will provide Santhera with gross funding totaling approximately CHF 69 million to drive growth, repay maturing bonds and extend cash runway through to the first half of 2026, at which point Santhera expects to be cash flow break-even.
"We are very pleased to have achieved significant financing goals for Santhera and our shareholders through these initiatives. The new financing is non- dilutive to shareholders, the royalty monetization is partial and capped, leaving upside potential to Santhera, and the debt repayment schedule aligns well with our growth expectations," said Andrew Smith, Chief Financial Officer of Santhera. "Importantly, it addresses our near term debt obligations and provides us with sufficient funding to drive market launches and growth of AGAMREE in Europe and to pursue additional development programs for AGAMREE."
Royalty monetization financing for AGAMREE totaling up to USD 38 million with R-
Bridge
Santhera is monetizing 75% of the future royalty income streams (net of any agreed payment obligations of Santhera to ReveraGen and Idorsia) from its licensing agreements for AGAMREE with Catalyst Pharmaceuticals, Inc. for North America and with Sperogenix Therapeutics Ltd. for China, in respect of net product sales occurring from July 1, 2024. R-Bridge will pay USD 30 million upfront upon closing of the transaction, less certain fees, and, in addition, staged sales-related milestone payments that, if achieved, would result in total
payments to Santhera of up to USD 38 million.
Payments to R-Bridge are capped, and once the agreed threshold or duration of royalty payments is met, the North America and China royalty payments will revert back to Santhera. Santhera will retain certain rights to buy back the royalty income stream.
The financing advances Santhera's commercialization of AGAMREE across Europe and
supports further clinical development, including post-approval commitments in Duchenne muscular dystrophy (DMD) and expansion into additional indications, the
latter together with partner Catalyst Pharmaceuticals, Inc.
Closing of the transaction is subject to conditions and is expected within the next 30 days.
New CHF 35 million term loan by Highbridge, coupled with conversion/maturity extension of private bonds
Santhera has entered into a commitment letter for a senior secured term loan financing with certain funds managed by Highbridge Capital Management, LLC (Highbridge), an existing investor in the Company. Subject to and upon closing, the financing instrument will provide CHF 35 million in a single draw. The loan has a four-year maturity with amortization in the amount of 15% per year, commencing after 24 months, and will pay a cash interest of 3-month SARON (floor
of 2%) plus 9.75% per year. Santhera has agreed to an original issue discount and a redemption premium. Under certain conditions, Santhera has the option for partial interest payments in kind and/or early loan redemption, both subject to a premium.
As part of the transaction, Highbridge will (1) extend the maturity of the private senior unsecured convertible bonds, with a strike price of CHF 10 and due in August 2024, by 12 months, (2) convert the private senior unsecured convertible bonds, with a strike price of CHF 5 and due in August 2024, (3) exercise the warrants it holds, and (4) receive 236,540 warrants, each of which is exercisable for one Santhera share at an exercise price of CHF 11.0975 at any
time during a five-year period.
The parties have entered into a commitment letter, which is subject to conditions, including documentation of the transaction. Funding is subject to certain conditions, covenants and documentation, and is expected within the next
30 days.
Use of proceeds from funding
The net proceeds from these financings will be used primarily to repay the outstanding amount of CHF 13.5 million of the public senior unsecured convertible bond due 2024 (SIX ticker SAN21, ISIN CH0563348744) as well as for product commercialization and general corporate purposes, extending the cash runway to anticipated cash flow break-even.
