LPTH Press Release: LightPath Technologies Announces Financial Results for First Quarter Fiscal 2015

ORLANDO, FL -- November 6, 2014 -- LightPath Technologies, Inc. (NASDAQ: LPTH) (“LightPath”, the “Company” or “we”), a global manufacturer, distributor and integrator of proprietary optical components, infrared lenses and high-level assemblies, announced today its financial results for the fiscal first quarter ended September 30, 2014. First Quarter 2015 Highlights: ·         12 month backlog increased approximately 25% to $5.3 million at September 30, 2014 as compared to June 30, 2014. ·         Bookings for optical lenses in the first quarter of fiscal 2015 were $3.45 million, the highest level in ten quarters. Bookings in Asia increased by 73% in the first quarter of 2015 as compared to the first quarter of fiscal 2014. ·         Revenue for the first quarter of fiscal 2015 decreased 7% to approximately $2.60 million compared to approximately $2.81 million for the first quarter of fiscal 2014 reflecting the more moderate economic growth in the Chinese market and a large delayed order from a major US defense contractor. ·         Gross margin as a percent of revenue for first quarter fiscal 2015 was 38% as compared to 47% in the first quarter of fiscal 2014. Lower gross margin was a result of duplicative manufacturing operations as we transition between our two facilities in China and a coating vendor yield issue ·         For the first quarter of fiscal 2015, net loss was approximately $(579,000), or $(0.04) per share, compared to net loss of $(80,000), or $(0.01) per share for the first quarter of fiscal 2014. ·         Adjusted EBITDA for the first quarter of fiscal 2015 was approximately ($380,000) compared to approximately $168,000 in the first quarter of fiscal 2014. Jim Gaynor, President and Chief Executive Officer of LightPath, commented, “The first quarter of fiscal year 2015 is best summarized as one of mixed results. Our bookings for the quarter were $3.45 million, the highest level in the last ten quarters.  This led to our 12 month backlog increasing by 25% from the beginning of our current fiscal year. This growth outlook confirms the necessity for the investment that has been made to build and staff our recently completed manufacturing facility in China.” “Our revenue in the first quarter of fiscal 2015 was less than our projections; however, our focused segments of precision molded optics in the Asian market and infrared, experienced growth. In the first quarter of 2015, revenue for precision molded optics business sold in Asia grew by 9% compared to the same period in the prior year and we achieved better than expected growth in our infrared revenue as that business was up in the quarter by more than 47% year-over-year. Revenues from sales in the U.S. during the first quarter of 2015 decreased by 14% from the same period last year, impacted by the delay of a $230,000 order from a U.S. defense contractor. This order is now planned for the second quarter.” “We planned for lower gross margins in the first quarter compared to the fourth quarter due to expected impacts from the continued transition of manufacturing processes from our Shanghai factory to our new Zhenjiang factory, and the ramp-up of producing higher infrared volumes. We also experienced an unexpected vendor related yield issue during the quarter for infrared products that has been resolved. The cost of these issues is estimated at approximately $100,000.  We also incurred $50,000 of additional expense due to overlapping staff in both of our China locations during this transition period, while our Zhenjiang facility staff continues training. Together, these items impacted our gross margin by approximately 5 percentage points. In the long term, we expect our margins to surpass prior levels as production at the Zhenjiang facility reaches an optimal rate.”  “We actively managed our working capital in the first quarter, continuing to make important capital investments while taking a balanced approach managing our receivables, inventory and payables.  While Adjusted EBITDA was negative ($380,000) in the quarter, our cash usage from operations was only ($100,000).” “Addressing the previously disclosed securities purchase agreement with Pudong Science & Technology Investment (Cayman), Co. Ltd.,” Mr. Gaynor added, “we have continued to work with the U.S. government concerning the proposed investment.  We remain optimistic that we will receive the necessary governmental approvals to close the proposed transaction.  As we have previously stated, the proceeds from the sale of common stock are intended to provide working capital to support our continued growth through global expansion.” Financial Results for Three Months Ended September 30, 2014 Revenue for the first quarter of fiscal 2015 totaled approximately $2.60 million, which was a decrease of $206,000, or 7%, as compared to the same period of the prior fiscal year.   The decrease from the first quarter of the prior fiscal year was attributable to a decrease in sales of our precision molded lenses primarily due to the laser tool market in China and a delayed order from a major U.S. defense contractor, offset by an increase in sales of infrared and Gradium products. Despite the slowdown in the Asian laser tool market in the first quarter of fiscal 2015, the Company still expects further growth in sales of industrial tool products based on recent order activity.  Orders for infrared products are also expected to continue to grow. The gross margin percentage in the first quarter of fiscal 2015 was 38%, compared to 47% in the first quarter of fiscal 2014. Total manufacturing costs of $1.63 million increased by approximately $135,000 in the first quarter of fiscal 2015 compared to the same period of the prior fiscal year. The increase was primarily due to higher wages associated with the ramp up in infrared production and the overlapping manufacturing workforces during the transition of production between our two China facilities. During the first quarter of fiscal 2015, the Company also experienced an isolated yield issue with one of its coating vendors that resulted in additional expense. This yield issue is now resolved. During the first quarter of fiscal 2015, total costs and expenses increased by approximately $107,000 compared to the same period of the prior year. The increase was primarily due to an increase of approximately $70,000 in wages in support of the infrared business and approximately $30,000 in higher travel expenses associated with business development initiatives.  Total operating loss for the first quarter of fiscal 2015 was approximately $511,000 compared to an operating loss of approximately $62,000 for the same period in fiscal 2014. In the first quarter of fiscal 2015, the Company recognized a non-cash expense of approximately $54,000 related to the change in the fair value of derivative warrants issued in connection with the June 2012 private placement. In the first quarter of fiscal 2014, the Company recognized a non-cash expense of approximately $19,000 related to the change in the fair value of these warrants. The warrants have a five year life and this fair value will be re-measured each reporting period until the warrants are exercised or expire. Net loss for the first quarter of fiscal 2015 was approximately $(579,000) (including the $54,000 non-cash expense for the change in value of the warrant liability) or $(0.04) per basic and diluted common share, compared with a net loss of $(80,000) (including the $19,000 non-cash expense for the change in value of the warrant liability) or $(0.01) per basic and diluted common share for the same period in fiscal 2014. Weighted-average basic shares outstanding increased to 14,312,061 in the first quarter of fiscal 2015 compared to 13,567,712 in the first quarter of fiscal 2014 primarily due to the issuance of shares of common stock for the employee stock purchase plan, shares issued due to warrant exercises and shares issued upon the exercise of restricted stock units. Cash and cash equivalents totaled approximately $787,000 as of September 30, 2014. The current ratio as of September 30, 2014 was 2.7 to 1 compared to 3.0 to 1 as of June 30, 2014. Total stockholders’ equity as of September 30, 2014 totaled approximately $6.8 million compared to $7.3 million as of June 30, 2014.  As of September 30, 2014, the Company’s 12-month backlog was $5.3 million compared to $4.3 million as of June 30, 2014, a 25% increase.  Investor Conference Call and Webcast Details: LightPath will host an audio conference call and webcast on Thursday, November 6, at 4:30 p.m. ET to discuss the Company’s financial and operational performance for the first quarter of fiscal 2015.

LightPath has a patent portfolio that has been granted or licensed to it in these fields. For more information visit www.lightpath.com. The discussions of our results as presented in this release include use of non-GAAP terms “EBITDA” and “gross margin.”  Gross margin is determined by deducting the cost of sales from operating revenue. Cost of sales includes manufacturing direct and indirect labor, materials, services, fixed costs for rent, utilities and depreciation, and variable overhead. Gross margin should not be considered an alternative to operating income or net income, which is determined in accordance with Generally Accepted Accounting Principles (“GAAP”). We believe that gross margin, although a non-GAAP financial measure is useful and meaningful to investors as a basis for making investment decisions. It provides investors with information that demonstrates   our cost structure and provides funds for our total costs and expenses. We use gross margin in measuring the performance of our business and have historically analyzed and reported gross margin information publicly. Other companies may calculate gross margin in a different manner. EBITDA is a non-GAAP financial measure used by management, lenders and certain investors as a supplemental measure in the evaluation of some aspects of a corporation's financial position and core operating performance. Investors sometimes use EBITDA as it allows for some level of comparability of profitability trends between those businesses differing as to capital structure and capital intensity by removing the impacts of depreciation, amortization, and interest expense. EBITDA also does not include changes in major working capital items such as receivables, inventory and payables, which can also indicate a significant need for, or source of, cash. Since decisions regarding capital investment and financing and changes in working capital components can have a significant impact on cash flow, EBITDA is not a good indicator of a business's cash flows. We use EBITDA for evaluating the relative underlying performance of the Company's core operations and for planning purposes. We calculate EBITDA by adjusting net loss to exclude net interest expense, income tax expense or benefit, depreciation and amortization, thus the term "Earnings Before Interest, Taxes, Depreciation and Amortization" and the acronym "EBITDA."

Seminar: "Sensing molecules with frequency combs" By Dr. Konstantin Vodopyanov

Friday, November 7, 2014 12:00 PM to 1:00 PM
CREOL Room 103

Abstract:

Optical frequency combs produced in the visible spectral range by ultrafast mode-locked lasers have revolutionized precision spectroscopy and time metrology, culminating in the 2005 Nobel Prize in Physics. I will present a new technique for extending frequency combs to the highly desirable yet difficult-to-achieve mid-infrared range - the region of fundamental molecular vibrational-rotational resonances (fingerprints). The technique is based on subharmonic optical parametric oscillation (OPO) that can be considered as a reverse of second harmonic generation. Using ultrafast erbium or thulium fiber lasers as a pump, we produce frequency combs that are approximately octave wide and centered around 3 µm or 4 µm in wavelength. I will talk about coherent properties of the generated mid-IR combs, as well as their applications for trace molecular detection.

Abstract:

The optical-frequency magnetic and electric properties of cyclic plasmon-supporting metal nanoparticle oligomers are explored through a combination of scanning transmission electron microscopy (STEM)/electron energy-loss spectroscopy (EELS) simulation and first-principles theory. A tight-binding type model is introduced to explore the rich hybridization physics in these plasmonic systems and tested with full-wave numerical electrodynamics simulations of the STEM electron probe. Building from a microscopic electric model, connection is made at the macroscopic level between the hybridization of localized magnetic moments into delocalized magnetic plasmons of controllable magnetic order and the mixing of atomic p_z orbitals into delocalized pi molecular orbitals of varying nodal structure spanning the molecule. It is found that the STEM electrons are uniquely capable of exciting all of the different hybridized eigenmodes of the nanoparticle assembly---including multipolar closed-loop ferromagnetic and antiferromagnetic plasmons, giant electric dipole resonances, and radial breathing modes---by raster scanning the beam to the appropriate position. Comparison to plane-wave light scattering and cathodoluminescence (CL) spectroscopy is made. The presented work provides a unified understanding of the complete plasmon eigenstructure of such oligomer systems as well as of the excitation conditions necessary to probe each mode.

Abstract

Since the invention of the twisted nematic (TN) field-effect in 1970, the nematic liquid crystal display technology which is based on electric field-effects has made remarkable progress. Field-effects are characterized by polarization sensitive macroscopic molecular liquid crystal configurations with electrically tunable optical appearance. 

The unique electro-optical building block concept of field-effect LCDs enables the integration and individual optimization of anisotropic optical thin-films and silicon electronics in LCDs. The remarkable progress made over the past 45 years, renders today virtually all applications of the communication between man and machine possible. They range from reflective LCDs with “zero power” consumption, such as digital watch LCDs, or remotely controlled electronic price tags in Shopping centers, to iPhones and large size, ultra-high resolution 4k television LCDs. Since the beginnings in 1970 this development has been spurred by interdisciplinary R&D between physics, material sciences, synthetic chemistry, semiconductor electronics, and engineering. It includes TN-LCDs (1970), super-twisted nematic (STN)-LCDs (1980s), thin-film transistor (TFT)-addressed TN-LCDs for computer monitors in the early 1990s and beyond, and multi-domain LCD configurations. The latter became possible in the late 1990s either by electric fringe-field electrode geometries, or by photo-alignment/patterning of LC molecules. Further enhanced contrast, large angles of view and shorter response times were the result. Moreover, spin-offs into potential future types of field-effect LCDs, such as polymer stabilized blue phase LCDs and ferroelectric LCDs became possible. 

This development is reviewed with examples of the multidisciplinary R&D of the author and collaborators on electro-optical field-effects, liquid crystal materials and polarized optical alignment and alignment patterning of monomeric and polymeric liquid crystal molecules in LCDs and optical thin-films based on liquid crystal polymers.

Biography

Dr. Martin Schadt was born on 16th August 1938 in Liestal, Switzerland. After having gained practical experience as electrician Martin Schadt majored in experimental physics at the University of Basel, Switzerland, where he received his PhD in 1967. He was granted a two year post-doctoral fellowship at the National Research Council, Ottawa, Canada, where he continued his research on the electronic and optical properties of organic semiconductors. In 1969 he and D.F Williams patented the first solid state, organic light emitting display (OLED).  Dr. Schadt’s first professional association was with the watch company Omega, where he investigated atomic beam standards. In 1970 he joined the Central Research Laboratories of F. Hoffmann-La Roche Ltd., Basel. Except for two years in biophysics, his research focused on the development of electro-optical field-effects based on liquid crystals and on liquid crystal materials. 1970 Dr. Helfrich and Dr. Schadt invented the twisted nematic (TN)-effect at F. Hoffmann-La Roche. The Roche TN-field-effect patent was granted in 20 countries and was licensed world-wide to the emerging field-effect LCD industry by Roche. The invention initiated a paradigm change towards flat panel field-effect liquid crystal displays (LCDs) enabling today’s LCD industry. The search for correlations between molecular structures, material properties and display performance, which Dr. Schadt started in the early 1970s, enabled the development of new liquid crystals for TN- and subsequent field-effect applications. As a consequence the pharmaceutical company Roche established itself as a major liquid crystal materials supplier for the emerging LCD-industry. Apart from his pioneering work on OLEDs, the TN-effect and liquid crystal materials, Dr. Schadt and collaborators invented the linear photo-polymerization (LPP) technology in 1991 enabling alignment of liquid crystal molecules by light instead of mechanically. This opened up novel LCD configurations and LCD operating modes, as well as numerous anisotropic optical polymer thin-films. 

Until 1994 Dr. Schadt headed the Liquid Crystal Research Division of Roche. Based on its photo-alignment technology the Division was turned in 1994 into the spin-off company ROLIC Ltd, an interdisciplinary Research and Development Company which Dr. Schadt built-up and headed as CEO and delegate of the Board of Directors until his retirement from the operating business in October 2002. He is now active as a scientific advisor to research organisations and continues research in collaboration with partner companies as an independent inventor. He is inventor or co-inventor of 166 patent families filed in Europe (EP) and holds more than 119 US patents. He has published 191 papers in leading scientific journals, including chapters in 6 books. Dr. Schadt became a Fellow of the Society Information Display (SID) in 1992 and a Fellow of the European Academy of Sciences in 2011. He is inventor or co-inventor of 166 patent families filed in Europe (EP) and holds more than 119 US patents. He has published 193 scientific papers in leading scientific journals, has given more than 150 lectures and contributed to 6 books. He has received the following Awards: the Roche Research and Development Award (1987), a Special Recognition Award and a Best SID Paper Award (1987), the SID Karl Ferdinand Braun Award (1992). Together with W. Helfrich, he received the Aachener und Münchener Preis für Technik und angewandte Naturwissenschaften (1994) and the Robert-Wichard-Pohl Prize of the German Physical Society (1996). Together with W. Helfrich and James Fergason, he received the IEEE Jun-ichi Nishizawa Medal (2008). In 2009 he received the Eduard Rhein Technoloy Prize. The G.W. Gray Medal of the British Liquid Crystal Society and the Blaise Pascal Medal for Material Sciences of the European Academy of Sciences (2010). The Frederiks Medal, highest recognition award of the Russian Liquid Crystal Society (2011). The Charles Stark Draper Prize of the US National Academy of Sciences (known as the “Engineering Nobel Prize”) together with G. Heilmeier, W. Helfrich and P. Brody (2012). European Inventor Award 2013 for Lifetime Achievement (2013). Fellow of US National Academy of Inventors NAI (2013). Honorary Prof. of Sichuan University, Chengdu (2013). Honorary Prof. of Nanjing University, Nanjing (2013).

Seminar: "Semiconductor Nanomaterials for Information and Energy Technologies" by Dr. Yajie Dong

Monday, October 6, 2014 11:00 AM to 12:00 PM
CREOL Room 103

ABSTRACT:

Low dimensional nanomaterials (1 D nanowires and 0 D quantum dots) represent important nanoscale building blocks with substantial potential for exploring new device concepts and materials for nanoelectronics, optoelectronics and energy technology applications. Three examples will be presented.  First, I will discuss my discovery of unique rectified silver/amorphous silicon/crystalline silicon (Ag/a-Si/c-Si) crossbar resistive random access memory (RRAM) effect in c-Si/a-Si core/shell nanowires and provide a comprehensive comparison between nanowire based and planar silicon based Ag/a-Si/c-Si RRAMs. The history of how this accidental nanowire based discovery solved a decades-long sneak current problem in RRAM field and eventually evolved into a game changing mainstream flash memory successor, Crossbar Memory, will be presented. Then I will report the experimental realization of high efficiency single coaxial group III-nitride heterostructured nanowire photovoltaic devices and light emitting devices. Meanwhile, a universal van der Waals epitaxial growth strategy for compound semiconductor nanowire arrays will be discussed. The vision of how the combination of nanowire array growth and heterostructured nanowire devices could possibly change the substrate limited status of III-Nitride research fields will be outlined. Lastly, I will present how quantum dots materials innovation and novel device structure design/processing helped resolve one long standing issue for organic based light emitting devices, the efficiency roll off at high driving current density.
