On August 26, 2026, Space-Eyes, Inc. issued the following press release:

Space-Eyes Expands Defense and Maritime Capabilities with Exclusive Option to Acquire KMS Solutions, a Leading U.S. Navy Engineering Services Provider

Proposed acquisition would combine Space-Eyes’ AI-driven defense and geospatial technologies with KMS Solutions’ established Navy engineering, lifecycle support and mission expertise, creating a stronger platform for long-term growth across defense markets.

Highlights:

Miami, Florida, August 26, 2026 – Space-Eyes, Inc. (“Space-Eyes”), a provider of next-generation geospatial intelligence and AI-enabled technologies for defense, security and enterprise operations worldwide, announced today that it has entered into a purchase option agreement providing Space-Eyes the exclusive right to acquire 100% of KMS Solutions, LLC (“KMS”).

KMS is an ISO 9001:2015-certified systems engineering services company specializing in Navy in-service and developmental systems, components and payloads and providing cradle-to-grave engineering and lifecycle support for the U.S. Navy.

“Space-Eyes has spent several years building an AI-driven technology platform designed to help customers detect, understand and respond to increasingly complex threats,” said Capt. Jatin Bains, CEO and founder of Space-Eyes. “KMS would add highly complementary capabilities: decades of Navy engineering experience, mission knowledge and lifecycle-support expertise. We believe the combination with KMS will create a stronger defense technology platform bringing together innovative software and AI capabilities with the engineering discipline and operational understanding required to address real-world defense requirements. Importantly, KMS will give us experienced people who understand the Navy environment and can help us identify where our technologies may solve genuine mission problems and how those opportunities should appropriately be pursued.”

“KMS has built its reputation by understanding our customers’ missions and delivering engineering solutions with consistency, technical rigor and integrity,” said JP Heatherington, Chief Executive Officer of KMS. “We see considerable potential in combining that experience with Space-Eyes’ emerging technology capabilities. The opportunity is not about circumventing established acquisition processes; it is about bringing together complementary capabilities that can help us identify and solve increasingly complex mission challenges for our customers.”

The proposed acquisition represents a strategic expansion of Space-Eyes’ defense capabilities. KMS contributes an established engineering organization, experienced technical personnel, Navy mission knowledge and recurring engineering and sustainment activities. Space-Eyes contributes an expanding portfolio of AI-enabled geospatial, sensor-fusion and counter-drone technologies.

Together, the companies believe these capabilities can create a broader platform from which to pursue opportunities across maritime awareness, force protection and other defense missions while continuing to support KMS’ existing customers and contractual commitments. Both companies have already successfully teamed up for selection to receive a Participant Basic Agreement (PBA) to be included as a participant within the Next Generation Undersea Security Initiative (NG-USI) consortium. Strategic Systems Program (SSP) has announced that the NG-USI shall rapidly and efficiently carry out the development of prototype solutions that sustain and expand strategic superiority within broadly stated submersible operations focus areas of interest.

Under the terms of the option agreement, Space-Eyes may exercise its option to acquire KMS through December 31, 2026, subject to the completion of its proposed business combination with McKinley Acquisition Corporation (“McKinley”), and the effectiveness of the related registration statement. Financial details were not disclosed. KMS will continue to operate its business in the ordinary course while the parties evaluate and, if applicable, pursue the transaction. The option agreement is tied to the completion of Space-Eyes’ planned business combination with McKinley and the execution of a definitive acquisition agreement and other mutually satisfactory documentation with terms and conditions customary for acquisitions of this kind.

Space-Eyes delivers AI-powered, sensor-agnostic counter-drone solutions that detect, track, identify, and mitigate unauthorized drones across military, government, and critical infrastructure environments. Built on its proprietary CATE AI platform, the company integrates radar, RF, EO/IR, and satellite data into a unified operational picture while leveraging customers' existing sensor networks.

The same AI platform powers Space-Eyes' broader geospatial intelligence offerings, providing real-time awareness across land, sea, and air. With applications spanning counter-drone operations, maritime monitoring, wildfire detection, and satellite command and control, Space-Eyes is expanding into larger-scale production programs and growing its presence with government and enterprise customers.

On July 30, 2026, Space-Eyes and McKinley entered into a definitive business combination agreement. The proposed transaction was unanimously approved by the boards of directors of both Space-Eyes and McKinley and is expected to close in the fourth quarter of 2026, subject to customary closing conditions, including regulatory and shareholder approval. Upon closing, the combined company will be named Space-Eyes, Inc., and its common stock is expected to be listed on The Nasdaq Stock Market LLC (“Nasdaq”) and trade under the ticker symbol “CUAS”, subject to approval by Nasdaq.
