Management Commentary

“The second quarter of 2022 continued our evolution from a laboratory engaged in research and development of 3D metal printing technology into a solutions provider focused on deploying our technology on thousands of production printers,” said Brunsberg. “To highlight this transformation, we began doing business under the name ‘Sigma Additive Solutions’, conveying our ability to enable customers and OEM partner providers to use a standard set of patented quality metrics across 3D printers from different manufacturers, using different processes, for the total additive manufacturing industry.”

“Since implementation of our new business model in the first quarter, revenue is beginning to show growth aligned with feedback we are getting from the market that our product adjustments and approach are better aligned with customer needs. We believe a revenue tail is beginning to develop that will help us increase our foundational level and begin to make revenue more predictable over time, with a current backlog of orders which consists of a mix of subscriptions and perpetual sales.”

“We are highly focused on setting the quality standard for the industry by collaborating and supporting industry participants, from the most successful, to the new, up and coming 3D printer manufacturers, and integrating with additive manufacturing software solution providers. To that end, we recently welcomed amace Solutions to our OEM Partner Network, entering the India market with the 3D printing arm of the largest machine tool conglomerate in India. amace will integrate our PrintRite3D® monitoring and analytics technology into its production-ready machines to support customers with real-time quality monitoring and analytics. The agreement starts with multi-unit sales to support both internal future development and customer deployment. This brings us to a total of 4 OEM partners, which we believe are critical to our growth over time.”

“Looking ahead, we believe our new subscription model and transition to software only product options make Sigma accessible at scale for supporting qualification and production across thousands of machines at hundreds of customer sites. We are seeing solid pipeline growth, with 87% increase of total qualified opportunities from the second half of 2021 to the first half of 2022. Our goal is to dramatically lower the barriers to entry for the additive manufacturing industry and enable end users to expand their use of industrial 3D printing at a lower cost with higher quality results. We seek to significantly impact the entire AM quality continuum with scalable solutions that improve machine, process, and part quality. I look forward to providing additional updates in the months to come on our progress," Brunsberg concluded.

Second Quarter 2022 Financial Results

Revenue for the second quarter of 2022 totaled $236,660 compared to $144,148 for the second quarter of 2021.
