Sigma Labs Announces Fourth Quarter and Year End 2014 Financial Results

Company Poised for Significant Revenue Expansion in 2015

SANTA FE, N.M. – March 31, 2015 – Sigma Labs, Inc. (OTCQB: SGLB) (“Sigma Labs” or the “Company”), a developer of advanced, in process, non-destructive quality inspection systems for metal-based additive manufacturing and other advanced manufacturing technologies, today announced financial results for the three and twelve months ended December 31, 2014.

Recent Highlights

· In the fourth quarter, Sigma Labs announced that it signed a technology cooperation agreement with Additive Industries, B.V. which will increase collaboration within the 3D printing space. Under the agreement, the Company’s PrintRite3D® quality assurance software will be tested with Additive Industries’ next generation metal additive manufacturing (AM) equipment currently under development.

· The Company more recently announced its first contract, worth approximately $500,000, from GE Aviation as part of an “America Makes” additive manufacturing research project funded by the National Additive Manufacturing Innovation Institute (NAMII). As part of this award, additional contracts are anticipated from Honeywell Aerospace and Aerojet Rocketdyne, a unit of GenCorp.

· Subsequent to the Winter Meeting of Edison Welding Institute's Additive Manufacturing Consortium (AMC) at Oak Ridge National Laboratory (held February 3-4), Sigma Labs was selected to host this year’s AMC Fall Meeting. Sigma Labs’ President and CEO Mark Cola gave a presentation at the Winter Meeting on In-Process Quality Assurance (IPQA®) and will showcase the Company’s AM capabilities at the Fall Meeting, scheduled for October 28-29, 2015.

· Sigma Labs also announced it will host an open house event on April 14, 2015 for its EOS M290 additive manufacturing metal printer. The M290, upgraded with Sigma Labs’ proprietary PrintRite3D® software, will be presented to potential customers, industry participants, and local government officials.

· The Company is in the final stages of testing its ground-breaking PrintRite3D® DEFORM™ software, continuing its product rollout. DEFORM™ uses proprietary, in-process analytics to generate real-time geometrical models for each layer during the AM build cycle. Sigma Labs has already lined up several organizations for its initial beta release, including Honeywell Aerospace.

“Sigma Labs ended 2014 well positioned for strong top line growth this year,” said Mark Cola, President and CEO. “The sequential revenue expansion we saw in the fourth quarter is expected to continue, and we feel confident about the Company’s outlook given current contracts underway, RFQs in process, and the opportunities presented through multiple initiatives. Last year we successfully launched our PrintRite3D® INSPECT™ software and introduced our proprietary technology to numerous industrial and government organizations – resulting in several important partnerships and contract awards.

“Going forward, we believe the launch of our DEFORM™ software, combined with our onsite EOS M290 machine, will open further channels for growth. We continue to manage costs conservatively while taking the necessary steps – such as our upcoming open house and the AMC Fall Meeting – to showcase our applications’ capabilities. We’re working with some of the best-known names in the AM space and are confident that Sigma Labs is becoming established in academic, government, and industry circles for its unique technology; we remain focused on demonstrating our QA software and participating in programs that provide for additional data collection. In this way, we will expand the audience of potential customers – leading to new business development opportunities and a path to profitability in the quarters to come.”

2014 Fourth Quarter and Full Year Financial Results

Service revenue for the three and twelve months ended December 31, 2014 was approximately $0.2 million and $0.5 million, respectively, versus approximately $0.3 million and $1.1 million for the same periods in 2013. The revenue decline year-over-year was primarily due to unanticipated delays in the commencement of certain projects as the Company transitioned from a provider of engineering consulting services to product sales and metal AM contract manufacturing.

The Company reported a net loss for the three and twelve months ended December 31, 2014 of approximately $0.3 million and $3.1 million, respectively, or $(0.00) and (0.01) per diluted share, respectively, versus a loss of approximately $0.2 million and $0.7 million, respectively, or $(0.00) per diluted share (both), for the same periods in 2013. The higher loss reflects lower revenue and increased general and administrative expense, payroll expense, non-cash compensation expense and warrant expense.
