ISSC reported robust topline growth in Q2 2025, underscored by the Honeywell military product line contribution and stronger air transport/aftermarket demand. Revenue nearly doubled to $21.94 million from $10.74 million a year ago, delivering a YoY growth rate of approximately 104% and QoQ expansion of about 37%. The company achieved an EBITDA of $6.98 million and net income of $5.34 million, translating to an EBITDA margin of ~31.8% and a net income margin of ~24.3% for the quarter, supported by favorable product mix and operating leverage from military revenues. Management reiterated the strategic objective to derive at least 40% of revenue from military customers in fiscal 2025 and highlighted ongoing investments in the Exton, PA facility expansion, ERP/IT enhancements, and the integration of the Honeywell acquisition as key enablers of scalable growth.
However, ISSC’s profitability remains sensitive to mix-driven gross margin volatility and integration costs associated with acquisitions. Gross margin was 51.4% in Q2 2025—slightly down from 52.0% a year earlier but up from 41.4% in Q1 2025—reflecting the stabilization of margins on Honeywell products despite anticipated near-term lumpiness as manufacturing shifts consolidate. Free cash flow remained negative at -$0.27 million in the quarter mainly due to capex related to the Exton facility expansion and elevated working capital associated with higher revenue. The balance sheet shows solid liquidity with cash of $1.23 million at quarter end and $8.8 million of available financing capacity, while total debt stands at $27.40 million and net debt ~ $26.18 million, producing a leverage ratio around 1.4x. Management signaled expectations for continued revenue and EBITDA expansion, supported by a backlog of roughly $80 million and a strategic mix tilt toward defense programs.
In sum, ISSC is transitioning from a growth-by-acquisition phase to a scale-driven, high-EBITDA model anchored by a U.S.-based, vertically integrated production footprint. The near-term catalysts include successful Honeywell integration, completion of the Exton expansion by mid-2025, and ongoing military program wins, with the overarching risk that margin volatility and transition-related costs could temper quarterly performance. Investors should monitor: (1) execution of the Honeywell transition and supplier readiness, (2) the ramp of the Exton facility and utilization, (3) the military mix stability toward the 40% target, and (4) working capital dynamics and capex trajectory into fiscal 2026.
