Material Changes vs. Prior Period
- Revenue Growth: Net sales increased 89.7% quarter-over-quarter and 75.5% year-to-date, driven by new product launch ramps and the introduction of a major new customer.
- Margin Expansion: Gross margin improved to 45.0% in Q2 2026 from 40.1% in Q2 2025, primarily due to higher average selling prices (ASP) from new product mix. YTD margin decreased slightly to 44.4% compared to 46.3% in 2025, impacted by a non-recurring $1.6 million gain in Q1 2025 that did not repeat.
- Expense Increases: Operating expenses rose significantly. R&D expenses increased 58.9% QoQ due to higher IP development, contractor costs, and stock-based compensation (SBC). SG&A expenses increased 39.4% QoQ, driven by SBC, sales commissions, and public company compliance costs.
- Liquidity Event: The company completed two follow-on offerings in 2026 (January and June), raising a combined net of approximately $243.2 million, significantly bolstering cash reserves from $140.3 million at year-end 2025 to $366.8 million.
Guidance, Outlook, and Risks
- Outlook: Management expects to continue investing heavily in R&D to expand product portfolios. The company anticipates cash on hand will fund operations for at least the next 12 months. Strategic focus remains on shifting geographic concentration away from Mainland China toward the U.S., Europe, and Asia (ex-China) to mitigate geopolitical risks.
- Customer Concentration: The top three end customers represented approximately 78% of net sales for Q2 2026 and 75% for the six months ended June 30, 2026. Loss of these customers would materially impact operations.
- Supply Chain: The company relies on a sole supplier for wafers (TSMC in Taiwan) and limited third-party manufacturers. Geopolitical instability or supply chain disruptions pose significant risks.
- Secondary Listing: On July 30, 2026, the company completed a secondary listing on the Singapore Exchange (SGX-ST), introducing risks related to cross-border trading liquidity and regulatory compliance.
- Non-GAAP Measures: Non-GAAP net loss for the six months ended June 30, 2026, was $(6.8) million, compared to GAAP net loss of $(17.3) million, primarily due to the exclusion of stock-based compensation and depreciation/amortization.
Investor Verification Checklist
- Verify the sustainability of the 89.7% revenue growth rate and the specific contribution of the "new major customer" mentioned in the MD&A.
- Assess the impact of the high customer concentration (top 3 customers = 78% of sales) on future revenue stability.
- Monitor the trajectory of R&D and SG&A expenses relative to revenue growth to determine the path to profitability.
- Review the company's strategy for mitigating supply chain risks associated with reliance on TSMC and potential geopolitical tensions.
- Confirm the burn rate and runway given the $20.7 million operating cash outflow for the first half of 2026, despite the recent capital raises.
