Arteris

Moat components and weights: Switching costs (40% weight, score 85): once a NoC is embedded into a customer’s SoC architecture and flows, replacing it is costly and risky, which tends to lock in platforms across multiple generations and drives long tail royalties. The company explicitly notes significant switching costs once designed into projects.

Intangibles (25% weight, score 75): the firm reports 148 patents with 138 applications, a long track record in NoC, and is used by 9 of the top 10 semiconductor companies across 975+ design starts and >4B units shipped, which reinforces know‑how and credibility.

Efficient scale (15% weight, score 75): the dedicated NoC vendor landscape has consolidated after Intel bought NetSpeed and Facebook bought Sonics, leaving Arteris as the primary independent specialist serving a relatively small but global niche. That scale and focus deter new entrants.

Network effects (10% weight, score 60): not a classic network, but there are soft effects through ecosystem integrations and reference wins that increase tool familiarity and IP interoperability over time.

Cost advantage (10% weight, score 55): high gross margins show product value but do not indicate a structural cost edge versus internal development at very large customers or versus Arm’s integrated offerings.

Overall, we see a narrow‑to‑moderate moat anchored in switching costs and efficient scale, with durability supported by rising complexity in AI and multi‑die architectures, yet still exposed to well‑funded competitors.
