L.O.T.W. #156 - HawkEye 360: Closes Senior Growth Capital and Mezzanine Term Loan
Silicon Valley Bank doubles down on its HawkEye 360 relationship - anchoring a $48.6 million two-facility financing package, alongside Pinegrove and Hercules as mezzanine lenders
In December 2025, HawkEye 360, Inc., a commercial space-based signals intelligence (SIGINT) company, closed a coordinated $48.6 million debt package alongside the cash-and-stock acquisition of Innovative Signal Analysis, Inc. (ISA) and the initial close of an $80 million Series E preferred raise led by NightDragon. The debt package was bifurcated into a $14.6 million senior growth capital term loan from Silicon Valley Bank (First Citizens Bank) and a $34.0 million second-lien mezzanine term loan agented by SVB / First Citizens. This week’s L.O.T.W. is a two-parter; the senior facility and the mezzanine facility are reviewed in stacked sections below, followed by the shared covenant package.

Business Overview: HawkEye 360 operates a commercial constellation of more than 30 satellites that collect radio frequency (RF) signal data and processes that data through proprietary AI/ML algorithms to deliver unclassified geospatial RF intelligence to defense, intelligence, and allied government customers. Founded in 2015 and headquartered in Herndon, Virginia, the company derives the majority of its revenue from U.S. Government and U.S. intelligence community contracts, with international customers contributing roughly 39% of revenue. Total revenue grew 74% in 2025 to $117.7 million (from $67.6 million in 2024), Adjusted EBITDA swung from negative $6.3 million to positive $24.8 million, and contracted backlog expanded nearly 7x to $302.7 million. The December 2025 acquisition of ISA, a Texas-based classified-cleared signal processing business, is intended to extend the company’s reach into the national security augmentation market by combining ISA’s classified architecture access and multi-domain detection capabilities with HawkEye’s commercial RF data stack.
