NOTE 1 – ORGANIZATION

Cemtrex was incorporated in 1998, in the state of Delaware and has evolved through strategic acquisitions and internal growth into a leading multi-industry technology company. The Company has expanded in a wide range of sectors, including smart technologies, virtual and augmented realities, industrial solutions, and intelligent security systems. Unless the context requires otherwise, all references to “we”, “our”, “us”, “Company”, “registrant”, “Cemtrex” or “management” refer to Cemtrex, Inc. and its subsidiaries.

The Company continuously assesses the composition of its portfolio businesses to ensure it is aligned with its strategic objectives and positioned to maximize growth and return in the coming years. During fiscal 2018, the Company made a strategic decision to exit its Electronics Manufacturing group by selling all companies in that business segment on August 15, 2019. Accordingly, the Company has reported the results of the Electronics Manufacturing business as discontinued operations in the Consolidated Statements of Operations and in the Consolidated Balance Sheets. These changes have been applied for all periods presented. During fiscal 2019, the Company also reached a strategic decision to exit the environmental products business, which was part of the Industrial Services Segment. Accordingly, the Company has reported the results of the environmental control products business as discontinued operations in the Consolidated Statements of Operations and in the Consolidated Balance Sheets.

Now the Company has two business segments, consisting of (i) Advanced Technologies (AT) and (ii) Industrial Services (IS).

Advanced Technologies (AT)

Cemtrex’s Advanced Technologies segment delivers cutting-edge technologies in the Internet of Things (IoT) and Smart Devices, such as the SmartDesk. Through the Company’s advanced engineering and product design, the Company delivers Virtual Reality (VR) and Augmented Reality (AR) solutions that provide higher productivity, progressive design and impactful experiences for consumer products, and various commercial and industrial applications. The Company is in the process of developing virtual reality applications for commercialization over the next couple years.

The AT business segment also includes the Company’s majority owned subsidiary, Vicon Industries, which provides end-to-end security solutions to meet the toughest corporate, industrial and governmental security challenges. Vicon’s products include browser-based video monitoring systems and analytics-based recognition systems, cameras, servers, and access control systems for every aspect of security and surveillance in industrial and commercial facilities, federal prisons, hospitals, universities, schools, and federal and state government offices. Vicon provides cutting edge, mission critical security and video surveillance solutions utilizing Artificial Intelligence (AI) based data algorithms.

Industrial Services (IS)

Cemtrex’s IS segment, offers single-source expertise and services for rigging, millwrighting, in plant maintenance, equipment erection, relocation, and disassembly to diversified customers. We install high precision equipment in a wide variety of industrial markets like automotive, printing & graphics, industrial automation, packaging, and chemicals among others. We are a leading provider of reliability-driven maintenance and contracting solutions for the machinery, packaging, printing, chemical, and other manufacturing markets. The focus is on customers seeking to achieve greater asset utilization and reliability to cut costs and increase production from existing assets, including small projects, sustaining capital, turnarounds, maintenance, specialty welding services, and high-quality scaffolding.

Going Concern Considerations

The Company has incurred substantial losses over the past two fiscal years and has debt obligations over the next fiscal year that raise going concern considerations. The Company has raised capital and will continue to reduce expenses through the use of (i) issuance of notes and subsequent settlement of such notes with equity, (ii) equity offering to qualified investors and at-the-market offerings, (iii) review and improve our business processes for more efficiency, (iv) sale or reallocation of fixed assets held from exited business segments to raise capital or increase revenue in continuing business segments, (v) development of additional products for the Advanced Technologies segment to increase revenues, (vi) cost reductions to improve overall profitability in all segments.
