CyberOptics Reports Third Quarter Operating Results

Minneapolis, MN—October 27, 2015—CyberOptics Corporation (Nasdaq: CYBE) today reported operating results for the third quarter of 2015 ended September 30.

Third quarter sales of products based upon the new 3D Multi-Reflection Suppression (MRS) inspection technology platform, including MRS sensors and the SQ3000 3D automated optical inspection (AOI) system, were unable to offset the sales declines of 2D AOI and solder paste inspection (SPI) systems. CyberOptics’ third quarter also was affected by lower sales of electronic assembly sensors due to soft demand from OEM customers selling into the Chinese market. Revenue for the first MX600 memory module inspection system was posted in the third quarter, with the same customer placing an order for one additional system. As a result, the MX600 backlog totaled approximately $3.4 million at September 30. If customer acceptance is received for multiple systems already shipped, a significant portion of this backlog would be converted into revenue in the fourth quarter.

Sales of semiconductor products, principally the WaferSense®/ReticleSense® product lines, declined 17% in the third quarter, reflecting a general slowdown in the semiconductor capital equipment market. Semiconductor revenue also was affected by production delays for the new Auto Multi Sensor (AMS) line, an all-in-one wireless solution that combines leveling, vibration and humidity measurements. As a result, a portion of anticipated AMS sales have been pushed into the fourth quarter. The company is optimistic about its semiconductor business, believing it should be a significant contributor to consolidated sales going forward. Third quarter LDI sales rose 27% year-over-year, reflecting a return to normal levels.

Dr. Subodh Kulkarni, president and chief executive officer, said: “We ended the third quarter with an order backlog of more than $2.0 million for our 3D MRS-enabled AOI products, which are steadily gaining traction in the marketplace. During the quarter, we sold additional SQ3000 systems and recorded further sales of 3D MRS sensors to KLA-Tencor under our long-term supply agreement. Sales to KLA are expected to increase in 2016 as our sensors are being incorporated into a growing portion of their back-end semiconductor packaging inspection systems. As previously reported, we have established a supply agreement with another OEM customer for 3D MRS sensors and have sold initial units for testing and demonstration purposes. Our customer expects to introduce its MRS-equipped inspection system in the fourth quarter, making us believe this new relationship has solid potential. We are pursuing additional OEM customers for our 3D technology in both the SMT and non-SMT markets. These initiatives are at varying stages, including initial product trials. We believe these potential relationships are promising, but as was the case with KLA, OEM supply agreements involve an extended period from product launch to ramped-up production. Our progress with these relationships makes us confident in our vision and strategy to be the leader in high precision 3D sensors.”

He continued: “The markets for 2D AOI and SPI systems have become highly competitive and a growing number of companies are transitioning from 2D AOI to 3D AOI to meet the increasingly demanding inspection requirements of the electronics and industrial markets. We believe sales of our new 3D MRS enabled AOI products will represent an increasing percentage of our AOI and SPI sales in the future. We believe our differentiated 3D MRS platform technology will provide us with a strong opportunity to capture meaningful market share in the 3D AOI market, due to the demonstrated competitive advantages of our MRS technology, and will be CyberOptics’ primary growth driver in coming years.”

Kulkarni said: “Although we have achieved our measurement accuracy targets for the MRS-equipped CyberGage inspection system in a lab environment, further improvement in consistency is required before customer beta testing can be launched. Interest in this product remains strong, and we presently anticipate initial CyberGage sales in the first half of 2016.”

He added: “Due to continued weakness in China’s manufacturing sector, our OEM customers are currently forecasting a decline in fourth quarter orders for electronic assembly sensors. However, fourth quarter sales are expected to benefit from our $10.5 million backlog at September 30, 2015, of which approximately $5.4 million represents orders for new SQ3000 3D AOI and MX600 system products. We believe customer acceptance will be received in the fourth quarter for a substantial portion of our SQ3000 and MX600 backlog. Assuming customer acceptance is received, revenue from these products would have a favorable impact on our results for the quarter. In addition, we are anticipating a solid rebound in fourth quarter semiconductor sales. Longer-term, the anticipated sales growth of our MRS-enabled products and promising outlook for the WaferSense/ReticleSense product lines make us very optimistic about CyberOptics’ future.”
