[6-K] Nano Labs Ltd Current Report (Foreign Issuer)

Rhea-AI Filing Summary

Nano Labs Ltd has furnished a Form 6-K highlighting a new, non-binding Memorandum of Understanding with ALT5 Sigma Corporation to evaluate potential collaboration in artificial intelligence infrastructure.

The companies plan a 90-day evaluation led by a joint working group. They will study three main areas: establishing AI data center infrastructure in North America, building an Agent Cloud platform for autonomous AI agents, and integrating AI-native payments by extending ALT5’s existing global payments, trading, and settlement systems to support machine-driven transactions.

The MOU only sets an evaluation framework and workstreams for technical and commercial diligence. Any actual business collaboration will require separate, definitive agreements that both parties must negotiate and approve after this assessment period.

Memorandum of Understanding regulatory

"announced the execution of a structured, non-binding Memorandum of Understanding (the “MOU”)"

A memorandum of understanding (MOU) is a formal agreement between two or more parties that outlines their shared intentions and plans to work together. It acts like a handshake in writing, clarifying each side’s roles and expectations before any official contract is signed. For investors, an MOU signals that parties are serious about collaboration, which can influence future business opportunities and potential growth.

AI data centers technical

"to jointly explore establishing North America AI data centers, Agent Cloud and AI Infrastructure"

AI data centers are specialized facilities built to store massive datasets and run powerful processors that train and operate artificial intelligence models — think of them as factories designed specifically for building and running AI. They matter to investors because they require large, ongoing capital and energy investments while driving revenue for cloud and chip providers; changes in demand, costs, or regulation can materially affect returns and company valuation.

Agent Cloud technical

"to jointly explore establishing North America AI data centers, Agent Cloud and AI Infrastructure"

A cloud of software 'agents' is a hosted network of small, semi‑autonomous programs that carry out tasks such as gathering data, making decisions, or executing trades on behalf of users or businesses. For investors, it matters because these agent clouds can speed up workflows, reduce labor costs, and enable new automated services—like a fleet of virtual assistants working together in the background to spot opportunities or manage risk, which can affect a company’s efficiency and competitive edge.

AI-native payments financial

"to evaluate collaboration across AI data centers, Agent Cloud, and AI-native payments"

AI-native payments are payment systems designed from the ground up to use artificial intelligence to make decisions like fraud detection, routing, pricing, user authentication and personalized payment experiences. For investors, they matter because AI can lower transaction costs, speed up processing, reduce losses from fraud and create new revenue streams through smarter recommendations and automation—similar to replacing a human clerk with a constantly learning digital assistant that handles most routine tasks more efficiently.

tokenization frameworks financial

"including tokenization frameworks, infrastructure monetization models, and security considerations"

Tokenization frameworks are the technical rules and platforms that convert real-world assets—such as stocks, bonds, property, or rights—into digital tokens that can be recorded and traded on a blockchain or similar ledger. They matter to investors because they make it easier to split ownership into smaller pieces, trade faster and with lower cost, and access new or previously illiquid markets; think of them as the blueprint that lets you slice a physical asset into many tradable shares and track ownership securely.

Exhibit 99.1

Nano Labs (NA) and ALT5 Sigma Corporation (ALTS) Announce Memorandum of Understanding to Jointly Explore Establishing North America AI data centers, Agent Cloud and AI Infrastructure  

HONG KONG, April 24, 2026 (GLOBE NEWSWIRE) -- Nano Labs Ltd (Nasdaq: NA) (“we,” the “Company” or “Nano Labs”), a leading Web 3.0 infrastructure and product solution provider, and crypto treasury company, today announced the execution of a structured, non-binding Memorandum of Understanding (the “MOU”) with ALT5 Sigma Corporation (Nasdaq: ALTS) (“ALT5”, collectively with Nano Labs, the “Parties”), to evaluate collaboration across AI data centers, Agent Cloud, and AI-native payments, supported by defined workstreams and joint leadership.

ALT5, which is in the process of changing its name to AI Financial Corporation and its Nasdaq ticker symbol to AIFC (“AiFi”), is an AI-powered fintech company operating institutional-grade global payments, trading, and settlement infrastructure.

The MOU establishes a defined evaluation process under which the Parties will assess potential collaboration across three primary areas: AI data centers, Agent Cloud, and AI-native payments. The evaluation will be conducted through a joint working group, a 90-day evaluation period, and a set of preliminary but defined workstreams intended to guide technical diligence, integration planning, and commercial exploration.

The Parties believe that recent advances in artificial intelligence, distributed computing, and digital financial infrastructure are accelerating the development of systems in which software agents operate autonomously across cloud environments and digital ecosystems. As these systems evolve, there is an increasing need for integrated infrastructure spanning compute resources, coordination layers, and financial settlement capabilities. The evaluation contemplated by the MOU is intended to assess how the Parties’ respective capabilities may align to address these emerging requirements.

These workstreams, as outlined in the MOU, span multiple layers of infrastructure and application, including compute systems, cloud orchestration, financial rails, tokenization frameworks, and related ecosystem components, and are designed to evaluate how the Parties’ respective capabilities may be integrated to support emerging AI-driven systems.

AI Data Centers

The Parties intend to explore the potential establishment of AI data center infrastructure in North America, including evaluation of compute infrastructure requirements for agentic AI workloads, deployment architecture, security considerations, and cost structure and commercialization pathways.

Agent Cloud

The Parties intend to explore the potential development of a cloud-based platform for AI agents, including evaluation of orchestration and runtime environments, identity and permissions architecture, integration across devices and applications, and interoperability requirements.

AI-Native Payments

The Parties intend to explore the integration of AI-native payment capabilities, extending ALT5’s existing global payments, trading, and settlement infrastructure to support machine-driven transactions, including AI-to-AI and AI-to-human payment flows, payment processing and settlement integration, and compliance and identity considerations.

In addition, the MOU contemplates evaluation of broader ecosystem components, including tokenization frameworks, infrastructure monetization models, and security considerations across AI and compute environments, which may be refined or reprioritized during the evaluation period based on technical findings and commercial considerations.

The collaboration is structured around a clear alignment of capabilities, with ALT5 contributing its expertise in global payments, trading, and financial infrastructure, and Nano Labs contributing its expertise in high-performance computing, chip design, and data center systems.

To support this process, the Parties have established a joint working group led by senior representatives from both organizations, responsible for coordinating evaluation activities, defining scope, and monitoring progress across the identified collaboration areas.

The Parties intend to conduct joint technical and commercial diligence throughout the evaluation period, including assessment of technical feasibility, integration pathways, and potential commercial applications. The objective of this evaluation is to determine whether one or more collaboration areas can support the development of technically feasible and commercially viable solutions.

Any decision to proceed toward definitive agreements will be based on the Parties’ mutual determination, following the evaluation process, that sufficient technical feasibility and commercial applicability have been demonstrated.

The MOU is non-binding, and any future collaboration remains subject to further negotiation and the execution of definitive agreements.
