Between May 13, 2026 and June 30, 2026, we acquired investments in the following Portfolio Companies, through SPVs: Prometheus Industries, Inc. and Shield AI Holdings, Inc. A brief description of each of these Portfolio Companies is included below:

Prometheus Industries, Inc.

Prometheus Industries, Inc. ("Prometheus") is an artificial intelligence company focused on applying advanced AI to the design and manufacturing of complex physical products across the industrial economy. Co-founded by Jeff Bezos and Vik Bajaj, formerly of Google X and Alphabet's Verily, and operating out of San Francisco, London, and Zurich, Prometheus is building what it describes as an "artificial general engineer": a set of AI tools designed to dramatically compress the time required to design, simulate, and manufacture complex physical systems. The company's technology targets pre-production optimization, including prototyping and tuning equipment and workflows, with initial focus areas spanning computing, aerospace, and automotive manufacturing. The underlying thesis is that AI-accelerated engineering represents a fundamental driver of civilizational productivity - compressing decade-long development cycles, such as jet engine design, by an order of magnitude or more.

Shield AI Holdings, Inc.

Shield AI Holdings, Inc. ("Shield AI") is a defense technology company developing AI-powered autonomous systems for military aviation and related domains. Founded in 2015 and headquartered in San Diego, California, the company was built around the thesis that AI pilots will power every category of military asset, and that a software-first approach could enable a new generation of defense technology capability. Shield AI's core product is Hivemind, a full autonomy stack that enables uncrewed aircraft to fly complex missions without GPS or communications in contested and degraded environments. The company works with eight of the top 25 defense primes, including General Atomics, Northrop Grumman, RTX, L3Harris, Kratos, and Airbus. Shield AI's V-BAT vertical takeoff and landing drone has been operationally deployed in Ukraine, where it has executed missions in GPS-denied and heavily jammed environments.
