Data center revenue grew 140% YoY to $107.7M and represents 56.1% of quarterly revenue, reflecting heavy dependence on AI/hyperscale market demand which could be subject to deployment timing volatility.
Operating cash burn was $73.8M for H1 2026 despite $191.9M Q2 revenue, primarily from $94.1M inventory buildup for anticipated demand and $69.6M accounts receivable increase, creating working capital pressure.
Company raised $1.03B net proceeds via ATM offerings in first half 2026 and is investing heavily in capacity: $335.1M capex in H1 2026 with expectation of elevated spending through end of 2027.
Amazon subsidiary warrant position: 1.3M shares vested at issuance; 6.6M additional shares may vest over 10 years upon $4B cumulative purchase threshold, creating future equity dilution contingent on customer spending.
