Follow the roadmap and you find the same supplier. Mobileye's first-quarter 2023 10-Q, filed May 11, 2023, is the company's early reporting as a freshly public entity, and it confirms that the supply-chain story flagged in the IPO prospectus has carried straight into the product roadmap. The filing states that successive generations of Mobileye's automotive-grade EyeQ SoC — including EyeQ5 and EyeQ6 — are produced with STMicroelectronics.

For a capital and supply-chain reader, the continuity is the point. A foundry relationship is not a one-time procurement; it is a multi-generation architectural commitment. Designing the EyeQ5 and EyeQ6 with STMicroelectronics means the next several years of Mobileye's product cycle are tied to that partner's process technology and capacity. That is efficient — deep partnership lowers integration risk — but it also extends the concentration exposure forward in time.

The filing does note that Mobileye has established a relationship with an additional foundry, which is the early evidence of the diversification a risk reader would want to see. Whether that second relationship becomes a meaningful second source or remains a hedge is a question the segment economics will answer over time; standing up a new automotive-grade chip at a new foundry is a multi-year, expensive undertaking, so diversification is slow by nature.

The accounting angle is inventory and cost. Mobileye's gross margin depends on the wafer pricing and yields it gets from its foundry, and its ability to meet design-win volumes depends on securing capacity. A reader tracking the segment should watch how chip-supply terms flow through cost of revenue and how inventory of EyeQ SoCs trends — rising inventory can signal either prudent buffering or softening demand.

The forward question from May 2023: does the additional foundry relationship mature into genuine dual-sourcing for the EyeQ line, or does the EyeQ5/EyeQ6 roadmap keep Mobileye structurally dependent on a single partner through the rest of the decade? The roadmap is committed; the diversification is, as of this filing, just beginning.

This analysis is grounded in Mobileye Global's Q1 2023 Form 10-Q as filed with the SEC and surfaced via EdgarBeast, the SEC filing data API and evidence index. The primary document is the filing.
