Exhibit 99.1
Robo.ai Announces Proposed Establishment of Alif
Maritec, a Marine Security and Intelligent Maritime Infrastructure Company
Wholly owned subsidiary of Alif Holding to focus on maritime protection,
smart ports, underwater intelligence and critical infrastructure protection; Dr. Jasem Al-Mansory expected to serve as Chairman
ABU DHABI, UAE, Sept. 9, 2026 — Robo.ai Inc. (Nasdaq: AIIO)
(“Robo.ai” or the “Company”) today announced that Alif Holding, the Company’s industrial group, plans to establish
Alif Maritec as a wholly owned subsidiary in the United Arab Emirates. The new company will focus on marine security and intelligent maritime
infrastructure. Dr. Jasem Al-Mansory, Chief Executive Officer of Alif Holding, is expected to serve as Chairman of Alif Maritec.
Alif Maritec will form part of Robo.ai’s broader intelligent infrastructure
platform. Once established, it will focus on four areas: maritime protection, smart ports, underwater intelligence and critical infrastructure
protection. The company will serve governments and infrastructure operators, addressing the above- and below-surface security needs of
ports, coastlines, offshore energy assets and other critical facilities.
Alif Maritec will develop underwater barrier and protection systems,
port and coastal protection systems, and an intelligent monitoring platform. Its technology framework will be built around four pillars:
AI and analytics, advanced sensing, marine materials and digital twin. Together, these capabilities will support an integrated approach
to situational awareness, intelligent analysis and coordinated response.
Demand for these solutions is being driven by continued growth of global
seaborne trade, increasing investment in offshore energy and nearshore infrastructure, and higher safety standards for ports and waterways.
Alif Maritec plans to integrate and manufacture its technology in the UAE in accordance with international standards. It will initially
serve markets across the Gulf Cooperation Council (GCC), before gradually expanding into international markets. This development path
is aligned with the UAE’s “We the UAE 2031” national vision and the “Make it in the Emirates” initiative, supporting
the localization of advanced industry, greater resilience across critical infrastructure and broader economic diversification.
Dr. Jasem Al-Mansory, Chief Executive Officer of Alif Holding and Chairman-designate
of Alif Maritec, said: “Alif Maritec brings our strategy to life: integrating global technology in the UAE, manufacturing in the
UAE and delivering solutions for markets worldwide. This approach closely aligns with the UAE’s national vision. Once established, Alif
Maritec will focus on protecting ports, coastlines, offshore energy assets and other critical facilities, both above and below the surface.”
At the group level, as previously announced, Robo.ai divested its legacy
business and acquired Neurovia AI and Quantum Core Capital (“QC Capital”) in the first half of 2026, and subsequently established
the industrial group Alif Holding. Together, these developments created a four-platform structure centered on intelligent infrastructure.
Net profit attributable to Robo.ai shareholders was US$46.7 million
for the first half, compared with a net loss in the prior-year period. The profit was primarily attributable to gains from discontinued
operations. From June 1 to August 31, 2026, Robo.ai generated more than US$180 million in total revenue, based on preliminary and unaudited
figures, reflecting the initial operating contribution of the Company’s repositioned business structure.
Benjamin Zhai, Chief Executive Officer of Robo.ai, said: “During
the first half of the year, we completed the Company’s restructuring, and in the second half, the new structure has begun translating
into ongoing operating results. The proposed establishment of Alif Maritec marks the next step in expanding our business footprint and
advancing Alif Holding’s ‘Building Intelligent Industries’ strategy. Through reliable, integrated system solutions, we aim to address
the security and protection needs of maritime infrastructure, while building a business that is positioned to deliver sustainable growth
and long-term shareholder value.”
The group financial figures cited in this press release are unaudited.
Group total revenue for the period from June 1 to August 31, 2026 is preliminary, has not been reviewed by the Company’s independent registered
public accounting firm and may be adjusted as a result of the Company’s financial closing and review procedures. Financial figures for
these specific historical periods do not constitute a forecast of, or guidance on, the Company’s results for any future period, and should
not be read as an expectation of future performance.
