Horizon Technology Finance Corporation (HRZN) announced on April 16, 2026 that it has extended a delayed‑draw senior credit facility of up to $25 million to Stellar Cyber, Inc., a company that develops an AI‑native, unified security operations platform for managed security service providers and enterprise teams.
The facility is a delayed‑draw structure that allows Stellar Cyber to draw funds as needed, with a draw‑down schedule tied to milestone achievements. The loan is intended to accelerate platform development, expand go‑to‑market reach, and support the company’s growth trajectory. The facility adds a high‑yield debt instrument to HRZN’s portfolio, reinforcing its focus on secured debt to venture‑backed companies.
HRZN’s recent financial performance shows a mixed picture. In Q1 2025, net investment income fell to $0.27 per share from $0.38 per share in the prior year, while Q4 2025 net investment income declined to $0.18 per share, missing analyst estimates of $0.30 per share. Despite these earnings misses, the company’s debt portfolio yield remained strong, at 15.0% in Q1 2025 and 14.3% in Q4 2025. The new loan is expected to modestly lift the overall portfolio yield, aligning with HRZN’s strategy to grow its capital base amid a pending merger with Monroe Capital Corporation.
Stellar Cyber has raised $68 million across seven funding rounds, with a Series B of $38 million in November 2021. The company’s valuation is not disclosed in the announcement, but the $25 million facility represents a significant capital injection to support its AI‑native platform, which already powers over 14,000 organizations through MSSP partners and offers more than 500 integrations. The loan will enable accelerated development and broader market penetration.
Management commentary: HRZN CIO Paul Seitz emphasized that deploying growth capital to high‑growth companies with proven momentum is a core focus of its venture lending platform. Stellar Cyber co‑founder and CEO Changming Liu noted that Horizon’s deep capabilities in venture lending make it a natural fit, and that the credit facility will allow the company to accelerate AI‑driven platform development and expand its go‑to‑market reach.
Strategic implications: The transaction expands HRZN’s exposure to the cybersecurity sector, a key growth area for the BDC, and adds a sizable, high‑yield instrument to its portfolio. For Stellar Cyber, the loan provides the working capital needed to scale its unified security operations platform and deepen its presence among managed security service providers and enterprise teams, positioning the company to capture increasing demand for AI‑enabled threat detection and response.
