Key Financial Metrics (Year Ended Dec 31, 2024)

Note: Non-GAAP metrics exclude significant stock-based compensation (SBC) expenses related to the IPO and ongoing equity awards.

Material Changes vs. Prior Period

• Revenue Growth: Revenue increased 242% year-over-year, driven by a 217% increase in unit shipments and a favorable product mix shift toward higher-value hardware modules.
• Margin Expansion: Gross margin improved by 750 basis points to 76.4%, primarily due to a $10.2 million reduction in inventory write-downs compared to 2023 (which included a legacy customer write-down).
• Expense Surge: Operating expenses increased 283% to $418.8 million. This was largely driven by a $223.1 million increase in non-cash stock-based compensation (due to IPO-related vesting) and a $52.0 million increase in personnel costs from a 57% headcount increase.
• Liquidity Position: Cash and marketable securities grew significantly to $914.3 million, bolstered by $672.2 million in net proceeds from the IPO.

Guidance, Outlook, Risks, and Unusual Items

• Outlook: Management expects continued investment in R&D and sales/marketing to support growth in AI and cloud infrastructure. The company anticipates operating expenses will increase in absolute dollars but decline as a percentage of revenue over time.
• Unusual Items: The 2024 financial results were heavily impacted by the IPO. This included a one-time recognition of $88.9 million in SBC expense for RSUs that met liquidity vesting conditions and $20.1 million in tax withholdings paid upon vesting.
• Key Risks:
  • Customer Concentration: The top three end customers represented approximately 80% of 2024 revenue. No single customer exceeded 40%.
  • Supply Chain: Reliance on a single manufacturing partner (TSMC) for ICs and limited partners for modules/boards creates supply risk, particularly given geopolitical tensions in East Asia.
  • Internal Controls: The company identified material weaknesses in internal control over financial reporting (risk assessment and IT general controls) which were not remediated as of December 31, 2024.
  • Profitability: While Non-GAAP metrics show profitability, the company reported a GAAP net loss of $83.4 million and an accumulated deficit of $208.8 million.

Investor Verification Checklist

• Customer Concentration: Verify the stability of relationships with the top three customers representing 80% of revenue.
• Internal Control Remediation: Monitor progress on remediation of material weaknesses in financial reporting and IT controls.
• Supply Chain Resilience: Assess contingency plans for reliance on TSMC and manufacturing partners in Taiwan/China amidst geopolitical risks.
• Stock-Based Compensation: Evaluate the trajectory of SBC expenses post-IPO and their impact on future GAAP profitability.
• Inventory Management: Confirm that inventory write-downs remain low compared to the $10.3 million charge in 2023.
