Q2-25 continuing ops showed top-line growth but remained unprofitable. Revenue rose 14% YoY to $13.0 M, driven by handheld device sales (+13%) and recurring revenue (+28%). Gross profit improved 3% to $6.4 M, yet margin contracted to 48.9% (53.8% LY) as product cost inflation outpaced pricing. Operating expenses climbed 47% to $21.5 M, largely from a $6.8 M fair-value increase in RedWave acquisition earn-out; R&D grew 23% and SG&A eased 7%. As a result, loss from continuing ops widened to $12.9 M (-$7.6 M LY), or –$0.36 per share.

Cash & equivalents jumped to $61.8 M (43.4 M YE-24) and marketable securities to $56.8 M, lifting current assets to $147.9 M. Total liabilities fell slightly to $42.9 M, though a new $11.6 M current liability reflects contingent consideration. Operating cash burn for H1 was $20.8 M, covered by divestiture proceeds; capex remained modest at $0.3 M. Shares outstanding were 36.06 M at 30 Jun 25. A June-25 master supply agreement secures $6.6 M in committed orders over three years, with a $0.75 M upfront payment received in July.
