Recent Events

MTI Instruments activities and 2007 milestones

MTI announced that strategic initiatives in 2006 at MTI Instruments, Inc. resulted in a revenue increase of 27.5% over fiscal year 2005. These initiatives include: new US and international sales and distribution channels; customer identification and retention programs; capital investments in manufacturing, engineering and quality processes; new branding; product development focused on creating families of products and services offering system solutions for customers; and establishment of a strategic relationship with one of Asia's leaders in lithography equipment for the microelectronics manufacturing industry.  2007 milestones for MTI Instruments include the introduction of next generation precision systems by the end of the second quarter, and an increase in annual revenues of at least 15% over 2006.

MTI Micro activities and 2007 milestones

MTI announced plans at MTI MicroFuel Cells Inc. to focus on commercializing low power Mobion^® products for the consumer market and suspend its high power program.

In May 2006, MTI Micro signed a strategic alliance with Samsung Electronics, a world leader in consumer products. As part of this agreement, Mobion^® technology was chosen to be developed for prototypes designed for mobile phones and accessories. The Company completed the initial delivery of low power prototypes and is working towards a 2007 milestone to complete shipment of the next generation low power advanced industrial design prototypes during the second quarter of 2007.

The Company announced another 2007 milestone to support its consumer product program: to sign an agreement with an additional OEM for low power products during the second half of 2007. The Company will commit increased resources to the consumer program and, with decreased funding and sales opportunities in the military market, will suspend its high power military product program, reduce its workforce by 20%, eliminate the position of COO at MTI Micro and pay severance and other benefits to employees in the amount of $0.3 million, resulting in annual savings projected to be approximately $5.8 million.  In addition, the Company remains committed to leveraging its low power consumer program to a selected number of low power applications in the military market.

The Company also announced plans for MTI Micro to develop partnerships and processes to start manufacturing readiness of Mobion^® consumer products in 2008; and to begin shipping products in the consumer market in 2009.  

Fourth Quarter Financial Results

For the three months ended December 31, 2006, the Company reported net loss of $3,336 thousand, or $(0.10) per diluted share, on revenues of $2,939 thousand.  Revenues included $2,761 thousand in product revenue generated by the Company's subsidiary, MTI Instruments and $178 thousand in funded research and development ("R&D") revenues generated by the Company's MTI Micro subsidiary.  This compares with net loss of $4,338 thousand, or $(0.14) per diluted share, on revenues of $2,229 thousand - $1,896 thousand generated by MTI Instruments and $333 thousand generated by MTI Micro - for the same period of 2005.  The $865 thousand, or 45.6% increase in MTI Instruments revenue is primarily the result of gauging instrumentation product sales, which have increased $689 thousand compared to the same quarter last year ($1,499 thousand in 2006 versus $810 thousand in 2005), led by capacitance sales to our Japanese distributor, coupled with increases to direct capacitance customers. Increases were also recorded in aviation revenues totaling $160 thousand while semiconductor product sales remained essentially flat. There was also a $155 thousand decrease in funded R&D revenue at MTI Micro primarily due to the suspension of existing Department of Energy (DOE) funding for 2006 and the completion of other programs which were active in 2005, partially offset by revenue recognized from a strategic alliance agreement totaling $168 thousand.

Operating loss for the fourth quarter of 2006 increased by $342 thousand, to $3,975 thousand compared to $3,633 thousand for the same period in 2005. This increase includes positive and negative revenue and expense changes. These changes include increased costs for research and product development expenses totaling $1,547 thousand, reflecting the ramp up of micro fuel cell commercialization efforts, including the development of prototypes and product intent prototypes; decreased funded R&D revenues of $155 thousand; partially offset by an increase of $579 thousand in gross margins related to the MTI Instruments sales increase and product mix change; and cost savings in selling, general and administrative expenses (SG&A) totaling $781 thousand - primarily reflecting savings attributable to reduced employee costs and increased wages charged to internal research activities.

Results for the quarter included $479 thousand and $182 thousand of gains on sales of available for sales securities and derivative instruments, respectively. There were no such gains during the same period in 2005. 

For the quarter ended December 31, 2006, cash used in operations was $2,704 thousand while cash used for capital expenditures was $707 thousand.

Annual Financial Results

For the twelve months ended December 31, 2006, MTI reported a net loss of $13,667 thousand or $(0.43) per diluted share, on revenues of $8,156 thousand.  Revenues included $7,667 thousand in product revenue generated by MTI Instruments and $489 thousand in funded R&D revenue generated by MTI Micro. This compares with a net loss of $15,094 thousand, or $(0.49) per diluted share, on revenues of $7,841 thousand during the same period of 2005, with $6,012 thousand in product revenue generated by MTI Instruments and $1,829 thousand in funded R&D revenue generated by MTI Micro. The $1,655 thousand increase in MTI Instruments revenue is the result of gauging instrumentation product sales, which have increased 55% since last year ($4,165 thousand in 2006 versus $2,688 thousand in 2005), led by increased sales of capacitance products to distributors, and to a new Japanese customer. Increases were also recorded in semiconductor product sales of $201 thousand; while aviation sales remained essentially flat as decreases in Air Force activity were offset by increases in commercial activity. The decrease in funded R&D revenue of $1,340 thousand is primarily the result of the suspension of existing DOE funding for 2006 and the completion of other programs which were active in 2005, partially offset by revenue recognized from a strategic alliance agreement totaling $427 thousand.

Operating loss for the twelve months ended December 31, 2006 increased by $2,639 thousand, to $17,737 thousand compared to $15,098 thousand for the same period in 2005. This increase includes positive and negative revenue and expense changes and the effects of the mandated adoption at the beginning of 2006 of the new accounting standard for share-based payments, which requires that the fair value of share-based compensation be estimated and recorded as an expense over the related service period. In the past, the Company only disclosed this information in its footnotes. These changes include: increased costs for non-cash stock-based compensation of $1,403 thousand; increased costs for research and product development expenses totaling $2,739 thousand reflecting the ramp up of micro fuel cell commercialization efforts, including the development of prototypes and product intent prototypes; decreased funded R&D revenues of $1,340 thousand due to the decrease in active contracts in 2006; partially offset by an increase of $1,136 thousand in gross margins related to increased MTI Instruments sales and product mix change and cost savings in SG&A expenses totaling $1,707 thousand - primarily reflecting savings attributable to reduced employee costs and increased wages charged to internal research activities.

Annual 2006 results also included a $4,289 thousand gain on the sale of securities available for sale compared to a $10,125 thousand gain for the comparable 2005 period, and a $182 thousand non-cash gain on derivative instruments compared to a $10,407 thousand loss in 2005 when a derivative instrument was fully exercised.

For the twelve months ended December 31, 2006, cash used in operations was $12,706 thousand while cash used for capital expenditures was $1,574 thousand. Cash provided by financing activities for the twelve months ended December 31, 2006 was $11,344 thousand, including $10,156 thousand from the Company's capital raise in December. Cash used in operations for the twelve months ended December 31, 2005 was $12,572 thousand while cash used for capital expenditures during the same period was $1,004 thousand.
