 2015 ANNUAL REPORT  

 
 
 
 
 
 
 
 
 
Dear Fellow Shareholders, 

I am very excited to be writing to you at the conclusion of a very successful year at Digirad – 2015 
was the most profitable year in Digirad’s history!  

We have been working hard over the last few years, building a stronger, more profitable company for 
all of you, and returning exceptional value along the way.   In the last year we have seen great stock 
price appreciation and we continue to return value with our consistent and sustained dividend.   

Further, we completed two compelling acquisitions that broadened our company scope and markets.  
The first, MD Office Solutions, which closed in March of 2015, opened up markets in Northern and 
Central California to us.  And the second, DMS Health Technologies, opened up several new services 
and expanded our market access across the entire United States, and further, we effectively doubled 
the  size  of  our  company.    We  are  now  more  than  just  a  diagnostic  imaging  company  –  we  are  a 
healthcare solutions company that sees abundant opportunities as we move forward to broaden and 
expand our reach into the healthcare industry.      

As I have stated over the last few years and will continue to state, we are not done yet.  As we look at 
our business and market moving forward, we are very excited about our prospects and our potential 
for  growth.    Of  course,  our  main  priorities  are  running  our  underlying  businesses  in  a  sustainable 
manner to generate cash and profit, and continued payment of our quarterly cash dividend.  However, 
looking to the future, we will continue to execute on our three tier growth strategy at Digirad: 

1.  Acquisitions.    Our  goal  is  to  acquire  companies  that  fit  within  our  business  model  of 
healthcare  solutions  on  an  as  needed,  when  needed  and  where  needed  basis  in  a  very 
financially disciplined manner. 

2.  New Services.  Adding new services that we can provide to our extensive service distribution 

channels. 

3.  Organic Growth.  Within our existing core business service lines and products.  

The entire Executive Team at Digirad is dedicated to this growth plan strategy, and we are working 
hard to ensure its continued deployment and continued value to YOU, our shareholder.  

 
 
 
 
 
 
 
 
 
 
 
 
Finally, I would like to thank all our employees; both employees that have been with Digirad for years 
and employees that have just joined.  Your hard work and dedication is an integral part of what we are 
accomplishing at Digirad. The Executive Team truly appreciates your hard work. 

Sincerely, 

Matthew G. Molchan 
President and Chief Executive Officer

Corporate Information

Digirad Corporation was incorporated in Delaware in 1997. Unless the context requires otherwise, in this report the terms “we,” 
“us,”  and  “our”  refer  to  Digirad®  Corporation  and  our  wholly-owned  subsidiaries,  Digirad  Imaging  Solutions®,  Inc., 
Telerhythmics®, LLC, and MD Office Solutions®.

ITEM 1.  

BUSINESS

Overview

Digirad delivers convenient, effective, and efficient diagnostic solutions on an as needed, when needed, and where needed 
basis. We are one of the largest national providers of in-office nuclear cardiology and ultrasound services, and also provide cardiac 
event monitoring services.  These services are provided to physician practices, hospitals, and imaging centers through our Diagnostic 
Services  reportable  segment.  We  also  sell  solid-state  gamma  cameras  for  nuclear  cardiology  and  general  nuclear  medicine 
applications, as well as provide service on the products we sell through our Diagnostic Imaging reportable segment.  

We designed and commercialized the first solid-state nuclear gamma camera for the detection of cardiovascular disease and 
other medical conditions. Our imaging systems are sold in both portable and fixed configurations, and provide enhanced operability 
and improved patient comfort. Our nuclear cameras fit easily into floor spaces as small as seven feet by eight feet, and facilitate 
the delivery of nuclear medicine procedures in a physician’s office, an outpatient hospital setting, or within multiple departments 
of a hospital (e.g., emergency and operating rooms).

Through Diagnostic Services, we offer a convenient and economically efficient imaging services program as an alternative to 
purchasing a gamma camera or ultrasound equipment or outsourcing the procedures to another physician or imaging center. For 
physicians who wish to perform nuclear imaging, echocardiography, vascular or general ultrasound tests, or any combination of 
these procedures in their offices, we provide the ability for them to engage our services, which includes the use of our imaging 
system, qualified personnel, and related items required to perform imaging in the their own offices and bill Medicare, Medicaid, 
or one of the third-party healthcare insurers directly for those services. The flexibility of our products and our service allows 
physicians to ensure continuity of care and convenience for their patients and allows them to retain revenue from procedures they 
would otherwise refer to imaging centers and hospitals. The imaging services are primarily provided to cardiologists, internal 
medicine physicians, and family practice doctors who enter into annual contracts for a set number of days ranging from once per 
month to five times per week. We experience some seasonality related to vacations, holidays, and inclement weather. Most of the 
imaging services are focused on cardiac care. Many of our physician customers are reliant on reimbursements from Medicare, 
Medicaid, and third-party insurers where, in the past, there has been downward price pressure and uncertainty of reimbursement 
rates due to factors outside the physicians’ control. The uncertainty created by the 2010 healthcare reform laws and other legislation 
has impacted our business in the past, and will likely have some impact on our business in the future. Future changes and related 
impacts may require modifications to our current business model in order for our physician customers and us to maintain a viable 
economic model.

With the acquisition of Telerhythmics, LLC (Telerhythmics) on March 13, 2014, we broadened our suite of service offerings 
through the Diagnostic Services segment, enabling the provision of outsourced cardiac event monitoring services. Providing these 
services offers flexibility and convenience to our customers who do not have to incur the costs of staffing, equipment, and logistics 
to monitor patients as part of their standard of care. Our cardiac event monitoring services are provided primarily through an 
independent diagnostic testing facility model which allows us to bill Medicare, Medicaid, or one of the third-party healthcare 
insurers directly for services provided. As such, our cardiac event monitoring services are directly subject to reimbursements from 

1

Medicare, Medicaid, and third-party insurers, which are subject to change on a periodic basis. Our cardiac event monitoring 
services are mainly provided to physician practices and hospitals. 

Our Diagnostic Imaging segment revenue results primarily from selling solid-state gamma cameras and camera maintenance 
contracts. We sell our imaging systems to physician offices and hospitals primarily in the United States, although we have sold a 
small number of imaging systems internationally.

For many years since our Initial Public Offering in 2004, we focused significant efforts on research and development activities 
to develop and further enhance our nuclear imaging cameras, primarily for alternative uses within the healthcare environment.  
These efforts, along with a fixed infrastructure that was sized for a much higher volume of manufacturing and sales of our nuclear 
imaging cameras than we have experienced, resulted in several years of financial losses. On February 28, 2013, we announced a 
plan to restructure our Diagnostic Imaging business to significantly reduce costs and improve profitability (the Diagnostic Imaging 
restructuring initiative). The Diagnostic Imaging restructuring initiative involved a reduction in force focused on manufacturing 
research and development, and administrative personnel. In addition, we entered into an agreement in September 2013 with a third 
party to outsource the majority of the manufacturing associated with our cameras. All restructuring efforts associated with the 
initiative were complete as of June 30, 2014. Further, on January 27, 2014, we entered into a termination agreement to end the 
lease on our 47,000 square foot former headquarters facility in Poway, California (the Facilities restructuring initiative) and moved 
our Diagnostic Imaging operations into a separate 21,300 square foot facility. All restructuring efforts associated with the Facilities 
restructuring initiative were complete as of December 31, 2014. With these restructuring initiatives complete, we plan to continue 
selling and servicing our cameras, but at a more profitable level with our restructured, leaner infrastructure. We believe that our 
cameras have underlying technology and related patents that make them relevant into the future. However, many other market, 
regulatory, and competitive factors could impact the effectiveness of our restructuring plan.  See Note 11 to the audited consolidated 
financial statements for further information.

Our main strategic focus is on growing our Diagnostic Services business, which we plan to accomplish by driving revenue 
density with our existing customers by providing additional service offerings, such as cardiac event monitoring, as well as by 
increasing our overall number of customers through territory expansion and acquisition of other health care solutions companies. 
Recently, these acquisitions have included the acquisition of Telerhythmics on March 13, 2014; our acquisition of MD Office 
Solutions on March 5, 2015, a provider of in-office nuclear cardiology imaging in the northern and central California regions; and 
most recently, on January 1, 2016, DMS Health Technologies (DMS Health), a provider of mobile healthcare solutions and a seller 
of medical equipment and services to small and regional hospitals throughout the United States, with a concentration in the upper 
Midwest  region.  The  scope  of  our  operational  footprint  within  the  United  States  on  a  basis  of  states  served  is  expected  to 
approximately double in 2016 compared to 2015 as a result of the DMS Health acquisition, and will significantly impact financial 
results going forward. In the future, we expect to continue to evaluate additional acquisition opportunities related to complementary 
healthcare solutions to diversify and expand our current offerings.

Market Opportunity

Nuclear Imaging

Nuclear imaging is a form of diagnostic imaging in which depictions of the internal anatomy or physiology are generated 
primarily  through  non-invasive  means.  Diagnostic  imaging  facilitates  the  early  diagnosis  of  diseases  and  disorders,  often 
minimizing the scope, cost, and amount of care required and reducing the need for more invasive procedures. Currently, the major 
types of non-invasive diagnostic imaging technologies available are: x-ray, magnetic resonance imaging (MRI), computerized 
tomography (CT), ultrasound, positron emission tomography (PET, which is a form of nuclear imaging), and nuclear imaging. 
The most widely used imaging acquisition technology utilizing gamma cameras is single photon emission computed tomography, 
or SPECT. All of our current cardiac gamma cameras employ SPECT technology.

Though  the  utilization  rates  of  competing  modalities  such  as  CT,  PET,  and  MRI,  and  diagnostic  procedures  such  as  CT 
angiography are high, SPECT procedures performed with gamma cameras are expected to continue to be used for a substantial 
number of cardiac-specific imaging procedures. We believe continued utilization of SPECT technology will be driven by patients 
having easier access to nuclear medicine services at physicians’ offices, lower purchase and maintenance costs, a smaller physical 
footprint, and easier service logistics of gamma cameras. 

Clinical Applications for Nuclear Imaging

Nuclear imaging is used primarily in cardiovascular, oncology, and neurological applications. Nuclear imaging involves the 
introduction of very low-level radiopharmaceuticals into the patient’s bloodstream, which are specially formulated to concentrate 
temporarily in the specific part of the body to be studied. The radiation signals emitted by the radiopharmaceutical materials are 
then converted into an image of the body part or organ. Nuclear imaging has several advantages over other diagnostic imaging 
modalities, showing not only the anatomy or structure of an organ or body part, but also its function including blood flow, organ 

2

function, metabolic activity, and biochemical activity. Cardiologists as well as a number of internists and other physicians either 
purchase our nuclear cameras or subscribe to our Diagnostic Services services for in-office cardiac imaging for these advantages. 

Ultrasound Imaging

Ultrasound imaging is a form of diagnostic imaging in which depictions of the internal anatomy are generated primarily through 
non-invasive means. Ultrasound imagers use sonar techniques to generate diagnostic images that facilitate the early diagnosis of 
diseases and disorders, often minimizing the scope and cost of care required and reducing the need for invasive procedures.

Clinical Applications for Ultrasound Imaging

Ultrasound is one of the most widely used imaging techniques in the United States. Ultrasound imaging is used primarily in 
obstetrics, internal medicine, cardiovascular care, and vascular health applications. Ultrasound imaging involves the transmission 
and detection of sound waves into and from a patient’s body. The sound waves transmitted by the ultrasound system are then 
converted into an image of the body part or organ. Ultrasound imaging also shows the anatomy or structure of many internal organs 
or body parts, as well as key functional information including blood flow, wall motion, and organ function. Our ultrasound services 
are used by cardiologists, internists, and other physicians for in-office echocardiography and general ultrasound imaging.

Cardiac Event Monitoring

Cardiac event monitoring is a diagnostic test that allows physicians to see the electrocardiogram (ECG) of a patient’s heart 
rhythm over a period of time or related to a specific event. The test includes a small monitor that is worn on the patient’s waist 
and is connected to lead wires affixed to the patient’s chest. The purpose of this test is to capture infrequent heart conditions that 
may only be experienced outside a physician’s office, as well as to observe the state of the heart in various resting and active 
situations.

Clinical Applications for Cardiac Event Monitoring

Cardiac event monitoring is a widely utilized cardiac test that provides clinical benefits in situations where the patient’s symptoms 
occur erratically or infrequently. Often symptoms can occur infrequently, but still be related to life-threatening cardiac conditions 
that need to be corrected. The use of a cardiac event monitor allows these symptoms to be captured and diagnosed, and ultimately 
corrected via prescription medications or use of invasive procedures, if required. 

Our Imaging Services

Diagnostic Services offers portable nuclear and ultrasound imaging services. We have obtained Intersocietal Accreditation 
Commission (IAC) and Intersocietal Commission for Echocardiography Laboratories (ICAEL) accreditation for our services. Our 
nuclear modality services include an imaging system, a certified nuclear medicine technologist and a cardiac stress technician 
(often  a  certified  or  trained  nurse  or  paramedic),  the  supply  of  radiopharmaceuticals,  and  required  licensing  services  for  the 
performance  of  nuclear  imaging  procedures  under  the  supervision  of  physicians.  Our  licensing  infrastructure  provides  the 
radioactive materials license, radiation safety officer services, radiation safety training, monitoring and compliance policies and 
procedures,  and  the  quality  assurance  function,  to  ensure  adherence  to  applicable  state  and  federal  nuclear  regulations.  The 
ultrasound imaging service is similar, in that we provide the ultrasound equipment and an experienced ultrasound technologist to 
perform the service.

Our portable nuclear imaging operations use a “hub and spoke” model in which centrally located regional hubs anchor multiple 
van  routes  in  the  surrounding  metropolitan  areas. At  our  Diagnostic  Services  hubs,  clinical  personnel  load  the  equipment, 
radiopharmaceuticals, and other supplies onto specially equipped vans for transport to the physician’s office or other customer 
locations,  where  they  set  up  the  equipment  for  the  day. After  quality  assurance  testing,  a  technologist  under  the  physician’s 
supervision  will  gather  patient  information,  inject  the  patient  with  a  radiopharmaceutical,  and  then  acquire  the  images  for 
interpretation by the physician.

We provide nuclear and ultrasound services primarily under contracts for services delivered on a per-day basis. Under these 
agreements, physicians pay us a fixed amount for each day and they commit to the scheduling of a minimum number of service 
days during the contract term, which typically runs for one year, as well as a variable cost associated with the associated volume 
of patients utilizing our services and radiopharmaceuticals. The same fixed payment amount is due for each day regardless of the 
number of patients seen or the reimbursement or payment obtained by the physician, practice, hospital, or imaging center.

Our Cardiac Event Monitoring Services

Diagnostic Services also offers remote cardiac event monitoring services. These services include provision of a monitor, remote 
monitoring by registered nurses, and 24 hours a day, 7 days a week monitoring support for our patients and physician customers.  

3

We offer modalities of: mobile cardiac telemetry (MCT), mobile cardiac event monitoring (both in wireless and analog versions), 
holter monitoring, and pacemaker analysis.  

Our monitoring service operates out of a centralized monitoring center located near Memphis, Tennessee. From this location, 
the majority of monitoring equipment is shipped directly to patient homes once they are enrolled in our service. Patients hook up 
the equipment with easy to follow instructions, as well as assistance from our monitoring center. Once they are hooked up to the 
monitoring device, patients are monitored for a period of time ranging from 2 to 30 days. At the conclusion of the monitoring 
period, the equipment is packaged up and sent back to our monitoring center, after which the equipment is redeployed to the next 
patient.  

We provide our services under contracts with our customers that typically allow for direct billing to Medicare, Medicaid, or 
third-party private payors once the monitoring cycle is complete. Typically, our contracts can be canceled at any time, and are 
generally present to create understanding on billing responsibilities.  

Our Products

Digirad sells a line of nuclear imaging cameras for nuclear cardiology and general nuclear medicine applications. Our cameras 
are used in hospitals, imaging centers, physician offices, and by mobile service providers. The central component of a nuclear 
camera is the detector, and it ultimately determines the overall clinical quality of the image a camera produces. Our nuclear cameras 
feature detectors based on advanced proprietary solid-state technology developed by us. Solid-state systems have a number of 
benefits  over  conventional  photomultiplier  tube-based  camera  designs  typically  offered  by  our  competitors.  Our  solid-state 
technology systems are typically 2 - 5 times lighter and considerably more compact than most traditional nuclear systems, making 
them far easier and less costly to build, very reliable, and able to be utilized for mobile applications. We are a market leader in the 
mobile solid-state nuclear camera segment. 

Our Cardius® family of dedicated cardiac SPECT solid-state imagers are noted for their compactness, portability, and unique 
upright imaging capabilities that make it possible to image patients up to 500 pounds in a sitting position. Upright imaging makes 
it possible to image large bariatric, chronic obstructive pulmonary disease (COPD), or claustrophobic patients that typically could 
not be imaged lying down on competitive systems. We offer fixed dual-head and triple-head cardiac camera models for dedicated 
use within a facility, and portable configurations that make it possible to move the system to provide service to multiple rooms or 
sites. Our Cardius® XACT SPECT/CT system features a triple-head design and a low dose volume CT attenuation correction 
methodology, making it possible to perform studies faster with greater interpretation diagnostic confidence. Our XACT camera 
is sought by departments seeking to improve productivity, increase clinical accuracy, or employ new low dose clinical protocols.

Our ergoTM large-field-of-view imaging system is targeted to hospitals with multi-camera general nuclear medicine departments, 
academic centers, pediatric hospitals, regional trauma centers, women’s health centers, and cancer centers. Most general nuclear 
medicine departments have the need for a single-head planar portable camera for imaging patients more conveniently on hospital 
stretchers, for imaging patients that can not be moved, and for imaging patient’s at their bedside (pediatrics, intensive care units, 
critical care units, emergency rooms, surgical suites, women’s health clinics, or on regular patient floors). A single-head planar 
camera provides a more economical and convenient way to perform approximately 25% or more of all studies commonly performed 
in general nuclear medicine. It also opens the door to perform studies on critically ill patients in the patient’s room and the ability 
to perform molecular breast imaging protocols that offer new revenue generation potential while improving the standard of patient 
care. 

Competitive Strengths

We believe that our competitive strength is our streamlined and cost efficient approach to providing medical services to our 

customers at the point of need, as well as our proprietary solid-state technology in general nuclear medicine and cardiology.

Imaging Services and Products

•  Broad Portfolio of Cardiovascular Imaging Services. One of our main competitive advantages is our ability to offer  
nuclear cardiology imaging, echocardiography imaging, and vascular imaging services. Our ability to offer multiple 
services strengthens our competitive position at each customer location. The depth of imaging services offered varies 
depending on the local market opportunity, availability of personnel, and credentialing requirements in the individual 
markets. 

•  Unique Dual Sales and Service Offering. We sell imaging systems to physicians who wish to perform nuclear imaging 
in  their  facilities  and  manage  the  related  service  logistics. Through  Diagnostic  Services,  we  offer  both  nuclear  and 
ultrasound services in which we provide our systems and certified personnel to physicians on an annual basis in flexible 
increments, ranging from one day per month to several days per week without requiring them to make a capital investment, 
hire personnel, obtain licensure, or manage other logistics associated with operating a nuclear imaging site. Our ability 

4

to service our customers in a variety of capacities from selling the capital equipment directly at the point of need or being 
more flexible in a service-oriented model allows us to serve our customers exactly according to their needs. 

• 

Leading Solid-State Technology. Our solid-state gamma cameras utilize proprietary photo-detector modules which enable 
us to build smaller and lighter cameras that are portable, with a degree of ruggedness that can withstand the vibration 
associated with transportation. We offer a more geometric-efficient design for cardiology and with our ergoTM imaging 
system, the first large field-of-view solid-state detector system for use in general nuclear medicine, pediatrics, women’s 
health, and surgery. 

•  Portable Applications through Reduced Size and Weight. Our cameras, depending on the model, weigh anywhere from 
600 to 1,000 pounds. Competitive anger photomultiplier tube-based technology cameras generally weigh 2 to 5 times as 
much. Our dedicated cardiac imagers require a floor space of as little as seven feet by eight feet and generally can be 
installed without facility renovations and use standard power. Our portable cameras are ideal for mobile operators or 
practices desiring to service multiple office locations or imaging facilities, and for use in our Diagnostic Services in-
office service business. We bring nuclear technology to the patient.

• 

• 

• 

Speed and Image Quality. We believe our Cardius® 3 XPO and X-ACT rapid imaging dedicated cardiac cameras, equipped 
with our proprietary nSPEED 3DOSEM software, can acquire images up to four times faster than conventional fixed 90 
or variable dual-head photomultiplier vacuum tube camera designs with equivalent image quality. Increased imaging 
speed optimizes workflow and resource utilization and allows for reduction of the administered dose of radiation to 
patients or the use of low dose imaging protocols, which we believe is increasingly of interest to our physician customers.

Improved  Patient Comfort and Utilization. We believe the upright and open architecture of our  patient chair on our 
imaging cameras reduces patient claustrophobia and increases patient comfort when compared to traditional vacuum 
tube-based imaging systems, the majority of which require the patient to lie flat and have detector heads rotate around 
the patient. Upright imaging positioning also reduces false indications that can result from organs pushing-up against the 
heart while patients are on their backs. Our Cardius® XPO camera series allows for the imaging of patients weighing up 
to 500 pounds.

Intellectual Property Portfolio. We have developed an intellectual property portfolio that includes product, component, 
and process patents covering various aspects of our imaging systems. We have 32 issued U.S. patents. We also license 
patents from third parties to enhance our product offering. In addition to our patent portfolio, we have developed proprietary 
manufacturing, business know-how, and trade secrets. This portfolio of intellectual property provides us with a distinct 
competitive advantage.

Cardiac Event Monitoring Services

•  Consistent and Relevant Portfolio of Services.  In addition to our imaging services, many of our customers require cardiac 
event monitoring services, and  prefer to deal  with one service  provider to  ensure  continuity of  services and  ease of 
communication. With this new service offering since our acquisition of Telerhythmics, we strengthen our position at each 
customer location.

•  Excellent  Customer  Service.  We  operate  our  cardiac  event  monitoring  services  utilizing  equipment  that  meets  our 
customers’ needs. We do not manufacture any cardiac event monitors ourselves, and are therefore not tethered to any 
particular device or product unlike many of our competitors; we utilize the best technology for our customers’ application 
and to meet their needs.

•  Utilization of Highly Trained Staff.  We staff our monitoring center only with registered nurses, which provides a much 
higher level of experience, analysis, and assistance to our customers. Many of our competitors staff their monitoring 
centers with lesser trained technicians that are not registered nurses, which can lead to poor customer service and poor 
clinical outcomes.

Business Strategy

Our goals are to achieve and maintain consistent profitability and operating cash flow generation, and grow our business over 

time via the following:

Diagnostic Services. As a result of our Diagnostic Imaging restructuring announced in February 2013, we have refocused our 
efforts to drive profitability and cash flow generation in our Diagnostic Services business, with efforts to help it grow over time.  
Since 2013, we believe the market has shown signs of stabilization in relation to healthcare reform and reimbursement uncertainties 
and we believe the market has been, and will be, more stable going forward. In addition, we believe that the market will be pushed 
more toward a “market efficient model,” similar to the model provided by our Diagnostic Services business.  Our model takes the 

5

inefficiencies often associated with medical practices owning their own capital equipment and providing their own staffing, and 
moves it into a streamlined and efficient operation, exactly where we believe healthcare of the future is moving to.

Further, we believe that we have the opportunity to focus our sales approach within our current operating markets to drive 
density of operations, which will allow us to take advantage of economies of scale and achieve better utilization of our capital 
equipment and personnel.  Finally, we also believe there are a variety of health care services businesses within the United States, 
both inside and outside our current operating markets, that we may be able to acquire and further increase our growth rate and 
density of operations. Our pattern of acquisitions over the last three years, including the acquisition of DMS Health on January 
1, 2016, illustrates the available acquisition opportunities within the healthcare services market and our intent to capitalize on 
those opportunities. 

As we have done in the past, we expect to continue supporting our physician customers by working with them to adjust our 
Diagnostic Services business model for changes in the market, as well as continuing to focus on aligning our labor and other costs 
with the variable nature of our revenue streams. Going forward, we continue to see value in our service channel via strategic and 
technological initiatives designed to increase revenue per day for us and our physician customers, as well as expand our service 
model offerings.

Diagnostic Imaging. In order to diversify our offerings beyond cardiac specific cameras, we have increased our efforts on 
markets beyond the cardiac-specific nuclear market. Our Cardius® XACT camera is particularly geared toward hospitals and large 
physician practices. Our ergoTM imaging system also addresses the larger market of general nuclear imaging and provides us with 
an enhanced market opportunity within the hospital. Our ergoTM imaging system is not just part of a hospital nuclear suite, it is a 
camera that enables the imaging to be performed wherever the patient is located, and has great promise in areas of the hospital 
where previously no nuclear imaging has been performed, such as the emergency room and the surgical suite. Further, as a result 
of our Diagnostic Imaging restructuring announced in February 2013, we have, and believe we can continue to maintain, the 
overall  profitability  and  cash  flow  from  our  Diagnostic  Imaging  business,  primarily  from  reduced  but  focused  research  and 
development efforts, reduced overhead and manufacturing costs, as well as our outsourced manufacturing operations. Further, we 
have developed relationships with distributors outside the United States that we believe may, over time, enhance our ability to 
increase sales of our nuclear imaging cameras outside the United States. See Note 11 to the audited consolidated financial statements 
for further information regarding our Diagnostic Imaging restructuring. 

Business Segments

Our business is organized into two reportable segments: Diagnostic Services and Diagnostic Imaging. See Note 15 to the 
audited consolidated financial statements for certain segment financial data relating to our business. For the year ended December 
31, 2015, we had one customer, Emory Healthcare, that exceeded 10% of our consolidated revenues. For 2015, Emory Healthcare 
represented 10.2% of our consolidated revenues and 13.4% of our Diagnostic Services revenues. For 2014, Emory Healthcare 
represented 10.9% of our consolidated revenues and 14.3% of our Diagnostic Services revenues. Prior to 2014, no single customer 
exceeded 10% of our consolidated revenues. We believe we have good relations with Emory Healthcare, however, if we were to 
lose Emory Healthcare as a customer, it would likely have a material adverse affect on our operations.  

Manufacturing

We manufacture our advanced, solid-state nuclear imaging cameras by employing a strategy that combines our internal design 
expertise and proprietary process technology with highly-qualified contract manufacturers. Prior to 2013, we manufactured the 
majority of the component parts associated with our cameras, along with selective outsourcing. In September 2013, we announced 
an agreement to move much of this process to a qualified, third party manufacturer, with the transition complete at the end of 
2014. We believe that our outsourcing efforts resulted in increased efficiencies, flexibility to meet customer demand, and cost 
reductions. We will continue to perform final assembly and final system performance tests at our facility. All of our outsourced 
suppliers of critical materials, components, and subassemblies undergo ongoing quality audits by us.

We and our contract manufacturers are subject to FDA Quality System Regulations, state regulations, such as those promulgated 
by the California Department of Health Services, and standards set by the International Organization for Standardization, or ISO. 
We are currently certified to the EN ISO 13485:2012 quality standard. We have received certification authorizing CE Marking of 
our Cardius® XPO, Cardius® X-ACT, and ergoTM gamma cameras, as well as U.S. Food and Drug Administration (FDA) 510(k) 
clearance for our complete nuclear imaging camera product line. The CE Mark is a requirement for selling in many international 
markets. In addition, the X-ACT camera utilizes an x-ray technology to provide attenuation correction information for the SPECT 
reconstruction. We also have received FDA Indications for Use for our ergoTM LFOV General Purpose Imager for molecular breast 
imaging.

Raw Materials

6

We, as well as our contract manufacturers, use a wide variety of materials, metals, and mechanical and electrical components 
for production of our products. In addition, our operations involve the use of radiopharmaceuticals. These materials are primarily 
purchased from external suppliers, some of which are single-source suppliers. Materials are purchased from selected suppliers 
based on quality assurance, cost effectiveness, and constraints resulting from regulatory requirements, and we work closely with 
our suppliers to assure continuity of supply while maintaining high quality and reliability. Global commodity supply and demand 
can ultimately affect pricing of certain of these raw materials. Though we believe we have adequate available sources of raw 
materials, there can be no guarantee that we will be able to access the quantity of raw material needed to sustain operations, as 
well as at a cost effective price.

Competition

The market for diagnostic services and nuclear imaging systems is highly competitive. Our business in the private practice and 
hospital sectors continues to face the challenges of demand for nuclear imaging equipment and diagnostic services, which we 
believe reflects in part, the impact of the Deficit Reduction Act on the reimbursement environment and the 2010 Healthcare Reform 
laws, competition from competing imaging modalities, such as CT angiography, PET, and hybrid technologies, as well as general 
uncertainty in overall healthcare and changes in healthcare, such as the Affordable Care Act. These concepts have impacted our 
operations. We believe that the principal competitive factors in our market include acceptance by physicians, including relationships 
that we develop with our customers, budget availability for our capital equipment, qualification for reimbursement, pricing, ease-
of-use, reliability, and mobility.

In  providing  Diagnostic  Services  imaging  services,  we  compete  against  many  smaller  local  and  regional  nuclear  and/or 
ultrasound providers, often owner-operators that may or may not follow all relevant healthcare laws and procedures, reducing 
their overall operating costs. The fixed-installation operators often utilize older, used equipment, and the mobile operators may 
use older Digirad single-head cameras or newer dual-head cameras. We are the only mobile provider with our own exclusive 
source of triple-head mobile systems. Some competing operators place new or used cameras into physician offices and then provide 
the staffing, supplies, and other support as an alternative to a Diagnostic Services service contract. In addition, we compete against 
imaging centers that install fixed nuclear gamma cameras and make them available to referring physicians in their geographic 
vicinity. In these cases, the physician sends their patients to the imaging center.

In providing cardiac event monitoring services, we compete against many smaller local and regional service providers, as well 
as against a few larger, well established medical device companies that provide devices and also provide a service model similar 
to ours. We believe our advantage in providing our services is the ability to utilize any cardiac event device on the market, and 
not being constrained by using any particular device.  However, our larger competitors have larger sales forces and deeper financial 
resources that may allow them to have higher cost efficiencies. Further, larger competitors may develop devices that may make 
our owned devices obsolete, causing us to suffer financial losses as we attempt to change our technology and service model to 
adapt. 

In selling our imaging systems, we compete against several large medical device manufacturers who offer a full line of imaging 
cameras for each diagnostic imaging technology, including x-ray, MRI, CT, ultrasound, nuclear medicine, or SPECT/CT and PET/
CT hybrid imagers. The existing nuclear imaging systems sold by these competitors have been in use for a longer period of time 
than our products and are more widely recognized and used by physicians and hospitals for nuclear imaging; however, they are 
generally not solid-state, light-weight, as flexible, or portable. Additionally, certain medical device companies have developed a 
version of solid-state gamma cameras which may directly compete with our product offerings. Many of the larger multi-modality 
competitors enjoy significant competitive advantages over us, including greater brand recognition, greater financial and technical 
resources,  established  relationships  with  healthcare  professionals,  broader  distribution  networks,  more  resources  for  product 
development and marketing and sales, and the ability to bundle products to offer discounts.

Sales

We maintain two sales organizations, which operate independently but in cooperation with each other: Diagnostic Imaging 
sales, which sells our nuclear gamma cameras and support, and our Diagnostic Services sales, which sells our mobile nuclear and 
ultrasound imaging services, as well as our cardiac event monitoring services. Relative to nuclear imaging, these sales teams work 
together to ensure that our customers make the right decisions in either utilizing our mobile imaging services or purchasing a 
nuclear imaging camera for whichever situation best suits their needs, volume, and overall impact to their business. Diagnostic 
Services sales teams are aligned across geographic areas we have established in order to better serve local market needs. Our 
Diagnostic Services business is segregated into twelve areas; each area is led by a local or regional business director who is 
responsible for the needs of our customers in that area and who has local operational responsibility. We expect to increase Diagnostic 
Services market penetration by focusing on those hospitals and practices that are already within an existing Diagnostic Services 
operational area in order to increase the density of our current operations and increase the efficiency of our overall cost structure, 
as well as cross selling our cardiac event monitoring services to our current nuclear and ultrasound imaging customers.  We also 

7

plan, over time, to utilize the customers and relationships that we have to offer other emerging services that have clinical need 
and can be provided while at that customer site.

The Diagnostic Imaging business sells imaging systems directly to physicians, primary care multi-specialty groups, clinics, 
and hospital customers in the United States. Diagnostic Imaging also has distribution agreements with third parties throughout 
the world and we believe, over time, these relationships can be developed to increase presence and sales to countries outside the 
United States.

Research and Development

In the past, we have committed a significant amount of resources to research and development activities, primarily surrounding 
developing new nuclear imaging cameras and alternative applications of that technology. In February 2013, we made a decision 
to change our strategic direction and focus efforts on expanding our Diagnostic Services business, as well as limiting our nuclear 
imaging system sales through Diagnostic Imaging to those cameras that already have a proven track record of quality, reliability, 
and customer need. Based on the new strategic direction, we have been focusing significantly less effort on developing new 
diagnostic imaging systems. We believe our current systems, with their state of the art technology and robust underlying patents, 
will be very relevant systems for many years into the future. We will continue to enhance and adjust our existing systems for the 
changing nuclear imaging market, including software updates and smaller enhancements. However, to accomplish any changes 
and enhancements, we will utilize what we believe is a deep available pool of contract engineers on a flexible, as needed basis. 
We have eliminated the fixed costs of a fully staffed research and development department, and as a result, we expect our research 
and development costs to be minimal going into the future. 

As mentioned previously, prior to early 2013, our research and development efforts have been primarily focused on developing 
our next generation products and alternative applications of our technology. Our research and development expense were zero in 
both 2015 and 2014, and $1.0 million in 2013.

Government Regulation

We and our medical professional customers must comply with an array of federal and state laws and regulations. Violations of 
such laws and regulations can be punishable by criminal, civil, and/or administrative sanctions, including, in some instances, 
exclusion  from  participation  in  healthcare  programs  such  as  Medicare  and  Medicaid. Accordingly,  we  maintain  a  vigorous 
compliance program and a hotline that permits our personnel to report violations while remaining anonymous if they wish. 

The following is a summary of some of the laws and regulations applicable to our business:

•  Anti-Kickback Laws. The Medicare/Medicaid Patient Protection Act of 1987, as amended, which is commonly referred 
to as the Anti-Kickback Statute, prohibits us from knowingly and willingly offering, paying, soliciting, or receiving any 
form of remuneration in return for the referral of items or services, or to purchase, lease, order, or arrange for or recommend 
purchasing, leasing, or ordering any good, facility, service, or item, for which payment may be made under a federal 
healthcare program. Violation of the federal anti-kickback law is a felony, punishable by criminal fines and imprisonment, 
or both, and can result in civil penalties and exclusion from participation in healthcare programs such as Medicare and 
Medicaid. Many states have adopted similar statutes prohibiting payments intended to induce referrals of products or 
services paid by Medicaid or other nongovernmental third-party payors.

•  Physician Self-Referral Laws. Federal regulations commonly referred to as the “Stark Law” prohibit physician referrals 
of Medicare or Medicaid patients to an entity for certain designated health services if the physician or an immediate 
family member has an indirect or direct financial relationship with the entity, unless a statutory exception applies. We 
believe that referrals made by our physician customers are eligible to qualify for the “in-office ancillary services” exception 
to the Stark Law, provided that the services are provided or supervised by the physician or a member of his or her “Group 
Practice,” as that term is defined under the law, the services are performed in the same building in which the physician 
regularly practices medicine, and the services are billed by or for the supervising physician or Group Practice. Violations 
of the Stark Law may lead to the imposition of penalties and fines, the exclusion from participation in federal healthcare 
programs, and liability under the federal False Claims Act and its whistleblower provisions. Many states have adopted 
similar statutes prohibiting self-referral arrangements that cover all patients and not just Medicare and Medicaid patients.

•  HIPAA.  The  Health  Insurance  Portability  and Accountability Act  of  1996,  or  HIPAA,  prohibits  schemes  to  defraud 
healthcare benefit programs and fraudulent conduct in connection with the delivery of, or payment for, healthcare benefits, 
items,  or  services.  HIPAA  also  establishes  standards  governing  electronic  healthcare  transactions  and  protecting  the 
security and privacy of individually identifiable health information. Some states have also enacted privacy and security 
statutes or regulations that, in some cases, are more stringent than those issued under HIPAA.

The American Recovery and Reinvestment Act of 2009, enacted February 17, 2009 made significant changes to HIPAA 
privacy and security regulations. Effective February 17, 2010, we are regulated directly under all of the HIPAA rules 

8

protecting the security of electronic individually identifiable health information and many of the rules governing the 
privacy of such information. 

•  Medical Device Regulation. The FDA classifies medical devices, such as our cameras, into one of three classes, depending 
on the degree of risk associated with the device and the extent of control needed to ensure safety and effectiveness. 
Devices deemed to pose lower risk are placed in either class I or II, which generally requires the manufacturer to submit 
to the FDA a pre-market notification requesting permission for commercial distribution. This process is known as 510
(k) clearance. Devices deemed to pose the greatest risk, such as life-sustaining, life-supporting, or implantable devices, 
are placed in Class III, requiring an approved Premarket Approval Application (PMA). Our cameras are Class II medical 
devices which have been cleared for marketing by the FDA. We are also subject to post-market regulatory requirements 
relating to our manufacturing process, marketing and sales activities, product performance, and medical device reports 
should there be deaths and serious injuries associated with our products.

•  Pharmaceutical  Regulation.  Federal  and  state  agencies,  including  the  FDA  and  state  pharmacy  boards,  regulate  the 

radiopharmaceuticals used in our Diagnostic Services business. 

•  Radioactive Materials Laws. We must maintain licensure under, and comply with, federal and state radioactive materials 
laws, or RAM laws. RAM laws require, among other things, that radioactive materials are used by, or that their use be 
supervised by, individuals with specified training, expertise, and credentials and include specific provisions applicable 
to the medical use of radioactive materials. 

Intellectual Property

We rely on a combination of patent, trademark, copyright, trade secret, and other intellectual property laws, nondisclosure 
agreements, and other measures to protect our intellectual property. We require our employees, consultants, and advisors to execute 
confidentiality agreements and to agree to disclose and assign to us all inventions conceived during the work day, using our 
property, or which relate to our business. Despite any measures taken to protect our intellectual property, unauthorized parties 
may attempt to copy aspects of our products or to obtain and use information that we regard as proprietary.

Patents

We have developed a patent portfolio that covers our overall products, components, and processes. We have 32 issued U.S. 
patents.  The  patents  cover,  among  other  things,  aspects  of  solid-state  radiation  detectors,  including  our  photodiodes,  signal 
processing, and system configuration. Our issued patents expire between October 13, 2015 and August 27, 2030. We have multiple 
patents covering unique aspects and improvements for many of our products. We have entered into royalty-bearing licenses for 
several U.S. patents with third parties, where we are the licensee, for exclusive or non-exclusive use in nuclear imaging (subject 
to certain reservation of rights by the U.S. Government). While each of our patents applies to nuclear medicine, many also apply 
to the construction of area detectors for other types of medical and non-medical imagers and imaging methods.

Trademarks

As of December 31, 2015, we hold trademark registrations in the United States for the following marks: 2020tc IMAGER®, 
Digirad®, DigiServ®, Cardius®, SPECTour®, SPECTpak Plus®, Solidium®, DigiTech®, Telerhythmics® and MD Office Solutions®. 
We have obtained trademark protection for some of these listed marks in the European Union and Japan.

Reimbursement

Our customers typically rely primarily on the Medicare and Medicaid programs and private payors for reimbursement. As a 
result, demand for our products and services are dependent in part on the coverage and reimbursement policies of these payors. 
Third party coverage and reimbursement is subject to extensive federal, state, local, and foreign regulation, and private payor rules 
and policies. In many instances, the applicable regulations, policies, and rules have not been definitively interpreted by the regulatory 
authorities or the courts, and are open to a variety of interpretations and are subject to change without notice.

The  scopes  of  coverage  and  payment  policies  vary  among  third-party  private  payors.  For  example,  some  payors  will  not 
reimburse a provider unless the provider has a contract with the payor, and in many instances such payors will not enter into such 
contracts without the approval of a third party “radiology benefit manager” that the payor compensates based on reducing the 
payor’s imaging expense. Other payors prohibit reimbursement unless physicians own or lease our cameras on a full-time basis, 
or meet certain accreditation or privileging standards. Such payor requirements and limitations can significantly restrict the types 
of business models we can successfully utilize.

Medicare reimbursement rules are subject to annual changes that may affect payment for services that our customers provide. 
In addition, Congress has passed healthcare reform proposals that are intended to expand the availability of healthcare coverage 

9

and reduce the growth in healthcare spending in the U.S. Many of these laws impact the services that our customers provide, and 
could change further over time.

Medicare reimbursement rules impose many standards and policies on the payment of services that our customers provide. For 
instance, physicians billing for the technical component of nuclear imaging tests must be accredited by a government-approved 
independent  accreditation  body  and  many  private  payors  are  adopting  similar  requirements. We  have  made  available  to  our 
customers a service to assist them in obtaining and maintaining the required accreditation. We believe we have structured our 
contracts in a manner that allows our customers to seek reimbursement from third-party payors in compliance with the law. Our 
physician customers typically bill for both the technical and professional components of the tests. Assuming they meet certain 
requirements including, but not limited to, performing and documenting bona fide interpretations and providing the requisite 
supervision of the non-physician personnel performing the tests, they may bill and be paid by Medicare. If the failure to comply 
is deemed to be “knowing” or “willful,” the government could seek to impose fines or penalties, and we may be required to 
restructure our agreements and/or respond to any resultant claims by such customers or the government. Our hospital customers 
typically seek reimbursement by Medicare for outpatient services under the Medicare Hospital Outpatient Prospective Payment 
System.

Employees

As of December 31, 2015, we had a total of 323 full time employees, of which 224 were employed in clinical related positions,  
41 in operational roles, 42 in general and administrative functions, and 16 in marketing and sales.  We also utilize varying amounts 
of temporary workers as necessary to fulfill customer requirements. We have not experienced any work stoppages and consider 
our employee relations to be good.

ITEM 1A. 

RISK FACTORS

Risks Related to Our Business and Industry

We may not be able to achieve the anticipated synergies and benefits from business acquisitions, including our recent 
acquisition of DMS Health Technologies, Inc.

Part of our business strategy is to acquire businesses that we believe can complement our current business activities, both 
financially  and  strategically.  On  January  1,  2016,  we  acquired  Project  Rendezvous  Holding  Corporation  (“PRHC”)  and  its 
subsidiaries, including DMS Health Technologies, Inc., with these synergistic benefits in mind.  Previously we acquired MD Office 
Solutions on March 5, 2015, and Telerhythmics, LLC, on March 13, 2014. Acquisitions involve many complexities, including, 
but not limited to, risks associated with the acquired business' past activities, loss of customers, regulatory changes that are not 
anticipated, difficulties in integrating personnel and human resource programs, integrating ERP systems and other infrastructures, 
general under performance of the business under Digirad control versus the prior owners, unanticipated expenses and liabilities, 
and the impact on our internal controls and compliance with the regulatory requirements under the Sarbanes-Oxley Act of 2002. 
There is no guarantee that our acquisitions will increase the profitability and cash flow of Digirad, and our efforts could cause 
unforeseen complexities and additional cash outflows, including financial losses. As a result, the realization of anticipated synergies 
or benefits from acquisitions may be delayed or substantially reduced.

Our revenues may decline due to reductions in Medicare and Medicare reimbursement rates.

  The success of our business is largely dependent upon our medical professional customers' ability to provide diagnostic care 
to their patients in an economically sustainable manner, either through the purchase of our imaging systems or using our diagnostic 
services, or both. Our customers are directly impacted by changes (decreases and increases) in governmental and private payor 
10

reimbursements for diagnostic services. We are directly and indirectly impacted by changes in reimbursements.  In our businesses, 
where we are indirectly affected by reimbursement changes, we make every effort to act as business partners with our physician 
customers.  For  example,  in  2010,  we  proactively  adjusted  our  diagnostic  imaging  services  rates  down  due  to  the  dramatic 
reimbursement declines that our customers experienced from the Centers for Medicare & Medicaid Services. Reimbursements 
remain a source of concern for our customers and downward pressure on reimbursements causes greater pricing pressure on our 
services and influences the buying decisions of our customers. Although the gap is closing, hospital reimbursements remain higher 
than in-office reimbursements. Our Diagnostic Imaging segment's products are targeted to serve the hospital market. A smaller 
portion of our Diagnostic Services business segment operates in the hospital market.

  Reductions  in  reimbursements  could  significantly  impact  the  viability  of  in-office  imaging  performed  by  independent 
physicians, as well as the viability of our cardiac event monitoring services business. The historical decline in reimbursements in 
diagnostic imaging has resulted in cancellations of imaging days in our Diagnostic Services business and the delay of purchase 
and service decisions by our existing and prospective customers in our Diagnostic Imaging business. 

Unexpected changes in our relationship with Emory Healthcare could result in a significant reduction in our sales and 
profits. 

  Emory Healthcare (Emory) has contributed a high percentage of our consolidated revenue. For 2015, Emory represented 10.2% 
of  our  consolidated  revenues  and  13.4%  of  our  Diagnostic  Services  revenues.  For  2014,  Emory  represented  10.9%  of  our 
consolidated revenues and 14.3% of our Diagnostic Services revenues. Prior to 2014, Emory did not exceed 10% of our consolidated 
revenues, however, they were still a significant customer. Although we expect that Emory will continue to be one of our most 
important customers, and we do not anticipate any near term changes in our relationship, our business could be materially adversely 
affected if Emory terminates its arrangement with us, negotiates lower prices, or otherwise alters the nature of its relationship with 
us. 

Our Diagnostic Services revenues may decline due to changes in diagnostic imaging regulations and the use of third party 
benefit managers by states and private payors to drive down diagnostic imaging volumes.

  Nuclear medicine is a “designated health service” under the federal physician self-referral prohibition law known as the “Stark 
Law,” which states that a physician may not refer designated health services to an entity with which the physician or an immediate 
family member has a financial relationship, unless a statutory exception applies. Our business model and service agreements are 
structured to enable our physician customers to meet the statutory in-office ancillary services (IOAS) exception to the Stark Law, 
allowing them to perform nuclear diagnostic imaging services on their patients in the convenience of their own office. From time-
to-time, the Centers for Medicare and Medicaid Services and Congress have proposed to modify the IOAS to further limit or 
eliminate  this  exception.  Various  lobbying  organizations  are  pushing  for,  and  the  Medicare  Payment Advisory  Commission 
(MedPAC) is actively discussing, recommending that Congress limit the availability of the IOAS exception in order to reduce 
federal healthcare costs. Legislation has been introduced in prior Congresses to modify or eliminate the exception, but has not 
been enacted. The outcome of these efforts is uncertain at this time; however, the limitation or elimination of the IOAS exception 
could significantly impact our Diagnostic Services business segment as currently structured.

  Our customers who perform imaging services in their office also experience the continuing efforts by some private insurance 
companies to reduce healthcare expenditures by hiring radiology benefit managers to help them manage and limit imaging. The 
federal government has also set aside monies in the 2009 recession recovery acts to hire radiology benefit managers to provide 
image management services to Medicare/Medicaid and MedPAC has recommended and the Centers for Medicare & Medicaid 
Services has, in the past, proposed legislation requiring Medicare physicians who engage in a relatively high volume of medical 
imaging be required to obtain pre-authorization through a radiology benefit manager. A radiology benefit manager is an unregulated 
entity that performs various functions for private payors and managed care organizations. Radiology benefit manager activities 
can include pre-authorization for imaging procedures, setting and enforcing standards, approving which contracted physicians can 
perform the services, such as requiring even the most experienced and highly qualified cardiologists to obtain additional board 
certifications, or interfering with the financial decision of the private practitioner by requiring them to own their own imaging 
system and not allowing them to lease the system. The radiology benefit managers often do not provide written documentation of 
their decisions or an appeals process, leaving leasing physicians unable to challenge their decisions with the carrier or the state 
insurance department. Unregulated radiology benefit manager activities have and could continue to adversely affect our physician 
customers' ability to receive reimbursement, therefore impacting our customers' decision to utilize our Diagnostic Services imaging 
services.

We  outsource  the  manufacturing  of  the  majority  of  the  components  associated  with  our  nuclear  gamma  cameras  to 
streamline operations and reduce costs. Outsourcing our manufacturing process may be difficult, could result in business 
disruptions caused by the outsource partner, and may not result in significant cost savings.

11

In September 2013, we announced an agreement to outsource the majority of our nuclear gamma camera production processes 
to a third party. We are now reliant on our third party manufacturer, which could expose us to any disruptions in their supply chain, 
processes,  employees,  and  other  underlying  activities  associated  with  their  manufacturing  process.  Should  we  experience  a 
disruption in their supplying of cameras, we may not be able to find a suitable alternative solution in a reasonable period of time 
which may cause a disruption in camera sales.

Manufacturing and providing service for our nuclear imaging cameras is highly dependent upon the availability of certain 
suppliers, thereby making us vulnerable to supply problems that could harm our business.

Our manufacturing process, even through an outsource manufacturer, and our after sale camera support business, relies on a 
limited number of third parties to supply certain key components of our products. Alternative sources of production and supply 
may not be readily available or may take several months to scale-up and develop effective production processes. If a disruption 
in the availability of parts or in the operations of our suppliers were to occur, our ability to have gamma cameras built as well as 
our  ability  to  provide  support  could  be  materially  adversely  affected. We  have  developed  backup  plans  and  have  alternative 
procedures should we experience a disruption. However, if these plans are unsuccessful, delays in the production and support of 
our gamma cameras for an extended period of time could cause a loss of revenue and/or higher production and support costs, 
which could significantly harm our business and results of operations.

Our Diagnostic Services operations are highly dependent upon the availability of certain radiopharmaceuticals, thereby 
making us vulnerable to supply problems and price fluctuations that could harm our business.

Our Diagnostic Service business involves the use of radiopharmaceuticals. There were significant disruptions in the international 
supply of these radiopharmaceuticals in 2010, which caused us to cancel services that would have otherwise been provided and 
this adversely affected our customers, as well as our financial condition in 2010. Since this event, we generally have had sufficient 
supply, but do experience short-term shortages from time to time. 

There is a limited number of major nuclear reactors supplying medical radiopharmaceuticals worldwide and there is no guarantee 
that  the  reactors  will  remain  in  good  repair  or  that  our  supplier  will  have  continuing  access  to  ample  supply  of  our 
radiopharmaceutical product. If we are unable to obtain an adequate supply of the necessary radiopharmaceuticals, we may be 
unable to utilize our personnel and equipment through our in-office service operations, or the volume of our services could decline 
and our business may be adversely affected. Shortages can also cause price increases that may not be accounted for in third party 
reimbursement rates, thereby causing us to lose margin or require us to pass increases on to our physician customers. 

Our business is not widely diversified.

  We provide our diagnostic services and sell our products primarily into the cardiac nuclear and ultrasound imaging private 
practice and in-office markets. We may not be able to leverage our assets and technology to diversify our products and services 
in order to generate revenue beyond the cardiac nuclear and ultrasound imaging private practice markets. If we are unable to 
diversify our product and service offerings, our financial condition may suffer.

We compete against businesses that have greater resources and different competitive strengths.

  The market for cardiac nuclear imaging cameras is limited and has experienced some declines. Some of our competitors have 
greater resources and a more diverse product offering than we do. Some of our competitors also enjoy significant advantages over 
us,  including  greater  brand  recognition,  greater  financial  and  technical  resources,  established  relationships  with  healthcare 
professionals, larger distribution networks, and greater resources for product development, as well as more extensive marketing 
and sales resources. If we are unable to expand our current market share, our revenues and related financial condition could decline.

In addition, our Diagnostic Services customers may switch to other service providers. Our Diagnostic Services segment, both 
in diagnostic imaging and cardiac event monitoring, compete against a variety of competitors, some of whom have the advantage 
of a lower cost structure, and in the case of diagnostic imaging, against imaging centers that install nuclear gamma cameras and 
make them available to physicians in their geographic vicinity. If these competitors are able to win significant portions of our 
business, our sales could decline significantly. Our financial condition could be adversely affected under such circumstances.

Our quarterly and annual financial results are difficult to predict and are likely to fluctuate from period to period.

  We have historically experienced seasonality in our Diagnostic Services business, and in the past, volatility due to the changing 
healthcare environment, the variable supply of radiopharmaceuticals, and the downturns based on the changing U.S. economy. 
While our physicians are typically obligated to pay us for imaging days to which they have committed, our contracts permit some 
flexibility  in  scheduling  when  services  are  to  be  performed.  We  cannot  predict  with  certainty  the  degree  to  which  seasonal 
circumstances such as the summer slowdown, winter holiday vacations, and weather conditions may affect the results of our 
operations. We have also experienced fluctuations in demand of our cardiac nuclear gamma cameras due to economic conditions, 

12

 
capital budget availability, and other financial or business reasons. In addition, due to the way that customers in our target markets 
acquire our products, a large percentage of our camera orders are booked during the last month of each quarterly accounting period. 
As such, a delivery delay of only a few days may significantly impact quarter-to-quarter comparisons of our results of operations. 
Moreover, the sales cycle in our Diagnostic Imaging segment for cameras is typically lengthy, particularly in the hospital market, 
which may cause us to experience significant revenue fluctuations. 

We spend considerable time and money complying with federal and state laws, regulations, and other rules, and if we are 
unable to fully comply with such laws, regulations, and other rules, we could face substantial penalties.

  We are directly, or indirectly through our physician customers, subject to extensive regulation by both the federal government 
and the states in which we conduct our business, including: the federal Medicare and Medicaid anti-kickback laws and other 
Medicare  laws,  regulations,  rules,  manual  provisions,  and  policies  that  prescribe  requirements  for  coverage  and  payment  for 
services performed by us and our physician customers; the federal False Claims statutes; the federal Health Insurance Portability 
and Accountability Act of 1996, or HIPAA, as amended in 2009 under the HITECH Act that places direct legal obligations and 
higher liability on us with respect to the security and handling of personal health information; the Stark Law; the federal Food, 
Drug and Cosmetic Act; federal and state radioactive materials laws; state food and drug and pharmacy laws and regulations; state 
laws  that  prohibit  the  practice  of  medicine  by  non-physicians  and  fee-splitting  arrangements  between  physicians  and  non-
physicians; state scope-of-practice laws; and federal rules prohibiting the mark-up of diagnostic tests to Medicare under certain 
circumstances. If our physician customers are unable or unwilling to comply with these statutes, regulations, rules, and policies, 
rates of our services and products could decline and our business could be harmed. Additionally, new government mandates will 
require us to provide a certain baseline of health benefits and premium contribution for our employees and their families or pay 
governmental penalties. Some of these costs are not tax deductible. We have opted to provide this coverage to our employee base 
in order to maintain retention of qualified medical technicians and other professionals rather than plan to pay penalties to the 
government. Either option will result in additional costs to us and could negatively impact our cash reserves.

  We maintain a compliance program to identify and correct any compliance issues and remain in compliance with all applicable 
laws, to train employees, to audit and monitor our operations, and to achieve other compliance goals. Like most companies with 
compliance programs, we occasionally discover compliance concerns. In such cases, we take responsive action, including corrective 
measures when necessary. There can be no assurance that our responsive actions will insulate us from liability associated with 
any detected compliance concerns.

If our past or present operations are found to be in violation of any of the laws, regulations, rules, or policies described above 
or the other laws or regulations to which we or our customers are subject, we may be subject to civil and criminal penalties, 
damages, fines, exclusion from federal or state health care programs, or the curtailment or restructuring of our operations. Similarly, 
if our physician customers are found to be non-compliant with applicable laws, they may be subject to sanctions which could have 
a negative impact on us. Any penalties, damages, fines, curtailment, or restructuring of our operations could adversely affect our 
ability to operate our business and our financial results. Any action against us for violation of these laws, even if we successfully 
defend against it, could cause us to incur significant legal expenses, divert our management's attention from the operation of our 
business, and damage our reputation. Although compliance programs can mitigate the risk of investigation and prosecution for 
violations of these laws, regulations, rules, and policies, the risks cannot be entirely eliminated. Moreover, achieving and sustaining 
compliance with applicable federal and state privacy, security, and fraud laws may prove costly.

Healthcare policy changes could have a material adverse effect on our business. 

In response to perceived increases in healthcare costs in recent years, there have been and continue to be proposals by the 
federal government, state governments, regulators, and third-party payers to control these costs and, more generally, to reform the 
U.S. healthcare system. Certain of these proposals could limit the prices we are able to charge for our products or the amounts of 
reimbursement available for our products, and could limit the acceptance and availability of our products. The adoption of some 
or all of these proposals could have a material adverse effect on our financial position and results of operations. 

A portion of our operations are located in a facility that may be at risk from fire, earthquakes, or other disasters.

Final assembly in our manufacturing process and significant portions of our inventory are located in a single facility in Poway, 
California, near known fire areas and earthquake fault zones. Future natural disasters could cause substantial delays in our operations 
and cause us to incur additional expenses. Although we have taken precautions to insure our facilities and continuing operations, 
as well as provide for offsite back-up of our information systems, this may not be adequate to cover our losses in any particular 
case. A disaster could significantly harm our business and results of operations.

The medical device industry is litigious, which could result in the diversion of our management's time and efforts, and 
require us to incur expenses and pay damages that may not be covered by our insurance.

13

 
 
  Our operations entail risks of claims or litigation relating to product liability, radioactive contamination, patent infringement, 
trade secret disclosure, warranty claims, vendor disputes, product recalls, property damage, misdiagnosis, breach of contract, 
personal injury, and death. Any litigation or claims against us, or claims we bring against others, may cause us to incur substantial 
costs, could place a significant strain on our financial resources, divert the attention of our management from our core business, 
and harm our reputation. We may incur significant liability in the event of any such litigation, regardless of the merit of the action. 
If we are unable to obtain insurance, or if our insurance is inadequate to cover claims, our cash reserves and other assets could be 
negatively impacted. Additionally, costs associated with maintaining our insurance could become prohibitively expensive, and 
our ability to become or remain profitable could be diminished.

Our ability to protect our intellectual property and proprietary technology through patents and other means is uncertain.

  Our success depends, in part, on our ability to protect our proprietary rights to the technologies used in our products. Any 
patents  we  have  obtained  or  do  obtain  may  be  challenged  by  re-examination  or  otherwise  invalidated  or  eventually  found 
unenforceable.  Both  the  patent  application  process  and  the  process  of  managing  patent  disputes  can  be  time  consuming  and 
expensive. Competitors may attempt to challenge or invalidate our patents, or may be able to design alternative techniques or 
devices that avoid infringement of our patents, or develop products with functionalities that are comparable to ours. In the event 
a competitor infringes upon our patent or other intellectual property rights, litigation to enforce our intellectual property rights or 
to defend our patents against challenge, even if successful, could be expensive and time consuming and could require significant 
time and attention from our management. We may not have sufficient resources to enforce our intellectual property rights or to 
defend our patents against challenges from others.

We may make financial investments in other businesses that may lose value.

As we look for the best ways to deploy our capital and maximize our returns for our businesses and shareholders, we may 
make financial investments in other businesses or processes for purposes of enhancing our supply chain, creating financial returns, 
strategic developments, or other purposes. These investments may be speculative in nature, and there is no guarantee that we will 
experience a financial return and we may lose our entire principal balance if not successful.

Risks Related to our Indebtedness
On January 1, 2016, we entered into a Credit Agreement (the “Credit Agreement”) by and among Digirad and certain subsidiaries 
of Digirad, the lenders party thereto, and Wells Fargo Bank, National Association as administrative agent and as sole lead arranger 
and sole book runner. The Credit Agreement is a five-year credit facility (maturing in January 2021) with a maximum credit amount 
of $40.0 million (the “Credit Facility”). On January 4, 2016, we drew down $33.6 million against the Credit Facility to fund the 
acquisition of DMS Health Technologies, Inc.

Our indebtedness could restrict our operations and make us more vulnerable to adverse economic conditions.

Our indebtedness could have important consequences for us and our stockholders. For example, the Credit Agreement requires 
us to dedicate a substantial portion of our cash flow from operations to payments on our indebtedness, thereby reducing the 
availability  of  our  cash  flow  to  fund  working  capital,  capital  expenditures,  and  acquisitions,  and  for  other  general  corporate 
purposes. In addition, our indebtedness could:

• 
• 
• 
• 

increase our vulnerability to adverse economic and competitive pressures in our industry;
place us at a competitive disadvantage compared to our competitors that have less debt;
limit our flexibility in planning for, or reacting to, changes in our business and our industry; and
limit our ability to borrow additional funds on terms that are acceptable to us or at all.

The Credit Agreement governing our indebtedness contains restrictive covenants that will restrict our operational flexibility 
and require that we maintain specified financial ratios. If we cannot comply with these covenants, we may be in default 
under the Credit Agreement.

The Credit Agreement governing our indebtedness contains restrictions and limitations on our ability to engage in activities 
that may be in our long-term best interests. The Credit Agreement contains affirmative and negative covenants that limit and 
restrict, among other things, our ability to:

incur additional debt;
sell assets;
incur liens or other encumbrances;

• 
• 
• 
•  make certain restricted payments and investments; 
• 
•  merge or consolidate.

acquire other businesses; and

14

In addition, the Credit Agreement limits, but does not eliminate, our ability to pay dividends. The Company expects to continue 
to pay its quarterly dividend consistent with past practice, however there is no assurance that the Company will be able to do so 
under the Credit Agreement.

Our Credit Agreement contains a minimum liquidity covenant, fixed charge coverage ratio covenant and a leverage ratio 
covenant. Events beyond our control could affect our ability to meet these and other covenants under the Credit Agreement. Our 
failure to comply with our covenants and other obligations under the Credit Agreement may result in an event of default thereunder. 
A default, if not cured or waived, may permit acceleration of our indebtedness. If our indebtedness is accelerated, we cannot be 
certain that we will have sufficient funds available to pay the accelerated indebtedness (together with accrued interest and fees), 
or that we will have the ability to refinance the accelerated indebtedness on terms favorable to us or at all. This could have serious 
consequences to our financial condition, operating results, and business, and could cause us to become insolvent or enter bankruptcy 
proceedings, and shareholders may lose all or a portion of their investment because of the priority of the claims of our creditors 
on our assets.

If we are unable to generate or borrow sufficient cash to make payments on our indebtedness, our financial condition 
would be materially harmed, our business could fail, and shareholders may lose all of their investment.

Our  ability  to  make  scheduled  payments  on  or  to  refinance  our  obligations  will  depend  on  our  financial  and  operating 
performance, which will be affected by economic, financial, competitive, business, and other factors, some of which are beyond 
our control. We cannot assure you that our business will generate sufficient cash flow from operations to service our indebtedness 
or to fund our other liquidity needs. If we are unable to meet our debt obligations or fund our other liquidity needs, we may need 
to restructure or refinance all or a portion of our indebtedness on or before maturity or sell certain of our assets. We cannot assure 
you that we will be able to restructure or refinance any of our indebtedness on commercially reasonable terms, if at all, which 
could cause us to default on our debt obligations and impair our liquidity. Any refinancing of our indebtedness could be at higher 
interest rates and may require us to comply with more onerous covenants, which could further restrict our business operations.

Increases in interest rates could adversely affect our results from operations and financial condition.

An increase in prevailing interest rates would have an effect on the interest rates charged on our variable rate debt, which rise 
and fall upon changes in interest rates. If prevailing interest rates or other factors result in higher interest rates, the increased 
interest expense would adversely affect our cash flow and our ability to service our indebtedness. 

Risks Related to our Common Stock

The market price of our common stock may be volatile, and the value of your investment could decline significantly.

The trading price of our common stock has been, and we expect it to continue to be, volatile. The price at which our common 
stock trades depends upon a number of factors, including our historical and anticipated operating results, our financial situation, 
announcements of new products by us or our competitors, our ability or inability to raise the additional capital we may need and 
the terms on which we raise it, and general market and economic conditions. Some of these factors are beyond our control. Broad 
market fluctuations may lower the market price of our common stock and affect the volume of trading in our stock, regardless of 
our financial condition, results of operations, business, or prospects. It is impossible to assure you that the market price of our 
shares of common stock will not fall in the future.

Our common stock has a low trading volume and shares available under our shelf registration statement and our option 
plan could affect the trading price of our common stock.

Our common stock historically has had a low trading volume. Any significant sales of our common stock may cause volatility 
in our stock price. We also have registered shares of common stock that we may issue under our shelf registration statement, our 
employee benefit plans, or from our treasury stock.  Accordingly, these shares can be freely sold in the public market upon issuance, 
subject to restrictions under the securities laws. If any of these stockholders, or other selling stockholders, cause a large number 
of securities to be sold in the public market without a corresponding demand, the sales could reduce the trading price of our 
common stock. One or more stockholders holding a significant amount of our common stock might be able to significantly influence 
matters requiring approval by our stockholders, possibly including the election of directors and the approval of mergers or other 
business combination transactions.

We adopted a tax benefit preservation plan, designed to preserve the value of certain income tax assets, primarily tax net 
operating loss carryforwards (NOLs), which may discourage acquisition and sale of large blocks of our stock and may 
result in significant dilution for certain stockholders.

We have adopted a tax benefit preservation plan in the form of a Section 382 Rights Agreement (the 382 Agreement). The 382 
Agreement is designed to preserve stockholder value and the value of certain income tax assets primarily associated with NOLs 
by acting as a deterrent to any person acquiring beneficial ownership of 4.99% or more of the Company’s outstanding common 
stock without the approval of the Board. The 382 Agreement may discourage existing 5% stockholders from selling their interest 

15

in a single block, which may impact the liquidity of the Company's common stock, may deter institutional investors from investing 
in our stock, and may deter potential acquirers from making premium offers to acquire the Company, factors which may depress 
the market price of our stock.

Anti-takeover provisions in our organizational documents and Delaware law may prevent or delay removal of current 
management or a change in control.

Our restated certificate of incorporation and amended and restated bylaws contain provisions that may delay or prevent a change 
in control, discourage bids at a premium over the market price of our common stock, and adversely affect the market price of our 
common stock and the voting and other rights of the holders of our common stock. In addition, as a Delaware corporation, we are 
subject to Delaware law, including Section 203 of the Delaware General Corporation Law. In general, Section 203 prohibits a 
Delaware corporation from engaging in any business combination with any interested stockholder for a period of three years 
following the date that the stockholder became an interested stockholder unless certain specific requirements are met as set forth 
in Section 203. These provisions, alone or together, could have the effect of deterring or delaying changes in incumbent management, 
proxy contests, or changes in control.

PROPERTIES

Our principal executive offices are located in an approximately 8,500 square foot facility in Suwanee, Georgia that had 
been leased to us on a month to month basis previously. On October 1, 2014, we entered into a long-term lease agreement for the 
same facility, extending our lease terms to November 30, 2021. Our former corporate headquarters were located in an approximately 
47,000 square foot facility in Poway, California. Consistent with our Facilities restructuring initiative, on January 22, 2014, we 
entered into a termination agreement to end the lease on the 47,000 square foot Poway, California facility as of April 30, 2014. 
The original term of the lease would have continued through February 29, 2016. Concurrently with the termination of the lease 
for the 47,000 square foot Poway, California facility, we entered into a new lease agreement on January 23, 2014 for a separate 
21,300 square foot facility in Poway, California to house our Diagnostic Imaging operations. The new lease agreement is for the 
term from March 1, 2014 through February 28, 2021. See Note 11 to the audited consolidated financial statements for further 
information.  In  addition  to  the  aforementioned  properties,  Diagnostic  Services  leases  approximately  28  additional  small  hub 
locations in the various states in which we operate, which primarily house our fleet of cameras and vans. The hub location lease 
terms typically range between one and five years. Diagnostic Services also operates a cardiac event monitoring center which is 
located in an approximately 8,078 square foot facility in Collierville, Tennessee. The lease will expire on March 12, 2021.

As of February 17, 2016 there were approximately 168 holders of record of our common stock. We believe that the number of 
beneficial owners is substantially greater than the number of record holders because a large portion of our common stock is held 
of record through brokerage firms in “street name.”

Dividend Policy

We paid four quarterly cash dividends of $0.05 per common share for total dividends paid of $0.20 per common share during 
the year ended December 31, 2015. We paid four quarterly cash dividends of $0.05 per common share for total dividends paid of 
$0.20 per common share during the year ended December 31, 2014. On February 1, 2016, we announced a dividend of $0.05 per 
common share payable on February 29, 2016 to shareholders of record as of February 16, 2016.

Our ability to pay dividends could be affected by future business performance, liquidity, capital needs, and financial covenants 
under our Credit Agreement with Wells Fargo. The Credit Agreement limits, but does not eliminate, our ability to pay dividends.  
We presently  intend  to  continue  the  payment  of  regular  quarterly  cash  dividends  on  our  common  stock,  however  there  
is no assurance that the Company will be able to do so under the Credit Agreement.

Sales of Unregistered Securities

None.

Issuer Purchases of Equity Securities

There were no issuer purchases of equity securities during the fiscal year 2015. 

On February 27, 2013, our board of directors modified our stock buyback program originally adopted in February 2009 to 
increase repurchases to an aggregate of $7.0 million, and subsequently, on March 13, 2013, increased the stock buyback program 
again for repurchases of up to an aggregate of $12.0 million. The timing of stock repurchases and the number of shares of common 
stock to be repurchased are in compliance with Rule 10b-18 under the Securities Exchange Act of 1934. The timing and extent of 
the repurchase depends upon market conditions, applicable legal and contractual requirements, and other factors.

MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF 
OPERATIONS

The following discussion contains forward-looking statements which involve risks and uncertainties. Our actual results could 
differ materially from those anticipated in these forward-looking statements as a result of various factors, including those set forth 
previously under the caption “Risk Factors.” This Management’s Discussion and Analysis of Financial Condition and Results of 
Operations should be read in conjunction with our audited consolidated financial statements and related notes included elsewhere 
in this report.

Overview

We are one of the largest national providers of in-office nuclear cardiology imaging and ultrasound services, and also provide 
cardiac event monitoring services. Our services are provided to physician practices, hospitals, and imaging centers through our 
Diagnostic  Services  reportable  segment. We  also  sell  solid-state  gamma  cameras  for  nuclear  cardiology  and  general  nuclear 
medicine applications, as well as provide service on the products we sell through our Diagnostic Imaging reportable segment. We 
designed and commercialized the first solid-state nuclear gamma camera for the detection of cardiovascular disease and other 
medical conditions. Our imaging systems are sold in both portable and fixed configurations, and provide enhanced operability 
and improved patient comfort. Our nuclear cameras fit easily into floor spaces as small as seven feet by eight feet, and facilitate 
the delivery of nuclear medicine procedures in a physician’s office, an outpatient hospital setting, or within multiple departments 
of a hospital (e.g., emergency and operating rooms).

We generate revenues within two primary reportable segments: Diagnostic Services and Diagnostic Imaging. Our primary 
service offering through Diagnostic Services is a convenient and economically efficient imaging services program as an alternative 
to purchasing a gamma camera or ultrasound equipment or outsourcing the procedures to another physician or imaging center. 
For physicians who wish to perform nuclear imaging, echocardiography, vascular or general ultrasound tests, or any combination 
of these procedures in their offices, we provide the ability for them to engage our services, which includes the use of our imaging 
system, qualified personnel, and related items required to perform imaging in their own offices and bill Medicare, Medicaid, or 
one of the third-party healthcare insurers directly for those services. The flexibility of our products and our service allows physicians 
to ensure continuity of care and convenience for their patients and allows them to retain revenue from procedures they would 
otherwise refer to imaging centers and hospitals. The imaging services are primarily provided to cardiologists, internal medicine 
physicians, and family practice doctors who enter into annual contracts for a set number of days ranging from once per month to 
five times per week. We experience some seasonality related to vacations, holidays, and inclement weather. Most of the imaging 
services are focused on cardiac care. Many of our physician customers are reliant on reimbursements from Medicare, Medicaid, 
and third-party insurers where, in the past, there has been downward price pressure and uncertainty of reimbursement rates due 
to factors outside the physicians’ control. The uncertainty created by the 2010 healthcare reform laws and other legislation has 
also impacted our business in the past, and will likely have some impact on our business in the future. Future changes and related 
impacts may require modifications to our current business model in order for our physician customers and us to maintain a viable 
economic model.

With the acquisition of Telerhythmics, LLC on March 13, 2014, we broadened our suite of service offerings provided through  
the Diagnostic Services segment, enabling the provision of outsourced cardiac event monitoring services. Providing these services 
offers flexibility and convenience to our customers who do not have to incur the costs of staffing, equipment, and logistics to 
monitor  patients  as  part  of  their  standard  of  care.  Our  cardiac  event  monitoring  services  are  provided  primarily  through  an 
independent diagnostic testing facility model which allows us to bill Medicare, Medicaid, or one of the third-party healthcare 
insurers directly for services provided. As such, our cardiac event monitoring services are subject to reimbursements from Medicare, 
Medicaid, and third-party insurers which are subject to change on a periodic basis. Our cardiac event monitoring services are 
mainly provided to physician practices and hospitals. 

Our Diagnostic Imaging segment revenue results primarily from selling solid-state gamma cameras and camera maintenance 
contracts. We sell our imaging systems to physician offices and hospitals primarily in the United States, although we have sold a 
small number of imaging systems internationally.

For many years since our Initial Public Offering in 2004, we focused significant efforts on research and development activities 
to develop and further enhance our nuclear imaging cameras, primarily for alternative uses within the healthcare environment.  
These efforts, along with a fixed infrastructure that was sized for a much higher volume of manufacturing and sales of our nuclear 
imaging cameras than we have experienced, resulted in several years of financial losses. On February 28, 2013, we announced a 
plan to restructure our Diagnostic Imaging business to significantly reduce costs and improve profitability (the Diagnostic Imaging 
restructuring initiative). The Diagnostic Imaging restructuring initiative involved a reduction in force focused on manufacturing, 
research and development, and administrative personnel. In addition, we entered into an agreement in September 2013 with a third 
party to outsource the majority of the manufacturing associated with our cameras. All restructuring efforts associated with this 
initiative were complete as of June 30, 2014. Further, on January 27, 2014, we entered into a termination agreement to end the 

22

lease on our 47,000 square foot former headquarters facility in Poway, California (the Facilities restructuring initiative) and moved 
our Diagnostic Imaging operations into a separate 21,300 square foot facility. All restructuring efforts associated with the Facilities 
restructuring initiative were complete as of December 31, 2014. With these restructuring initiatives complete, we plan to continue 
selling and servicing our cameras, but at a more profitable level with our restructured, leaner infrastructure. We believe that our 
cameras have underlying technology and related patents that make them relevant into the future.

Our main strategic focus is on growing our Diagnostic Services business, which we plan to accomplish by driving revenue 
density with our existing customers by providing additional service offerings, such as cardiac event monitoring, as well as by 
increasing our overall number of customers through territory expansion and acquisition of other healthcare solutions companies. 
Recently, these acquisitions have included the acquisition of Telerhythmics on March 13, 2014; our acquisition of MD Office 
Solutions on March 5, 2015, a provider of in-office nuclear cardiology imaging in the northern and central California regions; and 
most recently, on January 1, 2016, DMS Health, a provider of mobile healthcare solutions and seller of medical equipment and 
services to small and regional hospitals throughout the United States, with a concentration in the upper Midwest region. The scope 
of our operational footprint within the United States on a basis of states served is expected to approximately double in 2016 
compared to 2015 as a result of the DMS Health acquisition, and will significantly impact financial results going forward. In the 
future, we expect to continue to evaluate additional acquisition opportunities related to complementary healthcare solutions to 
diversify and expand our current offerings.

The financial and operational discussion that follows does not include the impact of the acquisition of DMS Health, which was 

completed on January 1, 2016.

Our Market

The target market for our products and services is comprised of cardiologists, internal medicine physicians, family practice 
physicians, and hospitals in the United States that perform or could perform nuclear and ultrasound diagnostic imaging procedures, 
or have a need for cardiac event monitoring. During the year ended December 31, 2015, through Diagnostic Services we provided 
imaging services to 663 physicians and physician groups and cardiac event monitoring services to 390 physicians and physician 
groups. Our Diagnostic Services business currently operates in 25 states. In the past our market has been negatively affected by 
lower physician reimbursements from the Center for Medicare and Medicaid Services (CMS) and third party insurance providers 
for the codes under which our physician customers bill for our services, although reimbursements have stabilized in the last few 
years. We have addressed, and will continue to address, these market pressures by modifying our Diagnostic Services business 
model, and by assisting our physician customers in complying with new regulations and requirements.

Trends and Drivers

The medical device and services industry, including the market for nuclear and ultrasound imaging systems and services and 
cardiac event monitoring, is highly competitive. Our business continues to be affected by many factors, including healthcare 
reimbursement rates, competition from alternative imaging modalities such as positron emission tomography (PET) and computed 
tomography (CT) angiography, competition from small owner-operated mobile nuclear imaging providers as well as from larger 
entrenched competitors in the cardiac event monitoring market, and general uncertainty in the healthcare marketplace. 

In our Diagnostic Services segment, our physician customers continue to experience uncertainty in reimbursements from CMS 
and third party insurance providers for the codes under which our physician customers bill for our services, although we have seen 
reimbursements stabilize in the last few years. In addition, there has been a trend of physician customers selling their practices to 
hospitals or larger healthcare systems and other doctors breaking away from hospital and healthcare systems, which affects both 
positively and negatively the volume of our service on a year by year basis. As a result, we are continuing to modify our offerings 
and pricing for our services upon contract renewal. The uncertainty over the enactment of future legislation that may impact 
reimbursement rates continues to linger and cause concern with our physician customers. We continue to consider modifications 
to our business model in order to adapt to environmental and regulatory changes in our dynamic healthcare marketplace.

In our Diagnostic Imaging segment, we continue to focus on single photon emission computed tomography (SPECT) products 
targeted  specifically  at  the  larger  physician  practices  and  hospital  marketplace.  The  most  widely  used  imaging  acquisition 
technology utilizing gamma cameras is single SPECT, and all of our current cardiac gamma cameras employ SPECT technology. 
Despite high utilization rates of competing modalities such as CT, PET, and MRI, and diagnostic procedures such as CT angiography, 
SPECT procedures performed with gamma cameras are expected to continue to be used for a substantial number of cardiac-specific 
imaging procedures according to industry experts. We believe continued utilization of SPECT technology will be driven by patients 
having easier access to nuclear medicine services at physicians’ offices, lower purchase and maintenance costs, a smaller physical 
footprint, and easier service logistics of gamma cameras. In an emerging trend in cardiology, SPECT technologies are being 
integrated with other imaging modalities, to form hybrid imaging modalities, such as SPECT/CT, resulting in improved clinical 
quality and diagnostic certainty.

2015 Financial Highlights

23

Our consolidated revenues were $60.8 million for the year ended December 31, 2015. This is an increase of $5.2 million, or 
9.4%, compared to the prior year period driven by a $4.2 million, or 10.0%, increase in our Diagnostic Services revenue year over 
year. The increase in Diagnostic Services revenue is primarily due to $2.6 million of incremental revenue associated with the MD 
Office acquisition, which occurred on March 5, 2015, as well as $1.6 million of incremental cardiac event monitoring revenue 
resulting from the Telerhythmics acquisition, which occurred on March 13, 2014. Excluding the impact of acquisitions, revenue 
in the Diagnostic Services business increased slightly compared to the prior year driven by an increase in the number of days our 
physician customers utilized our imaging services, partially offset by a decrease in our average mobile imaging rate per day and 
a decrease in ancillary revenue from short-term equipment rentals. Diagnostic Imaging segment revenues for the year ended 
December 31, 2015 increased by $1.0 million, or 7.3%, compared to the prior year, primarily due to an increase in the volume of 
cameras  sold.  The  number  of  cameras  sold  increased  to  31  from  27  during  the  years  ended  December 31,  2015  and  2014, 
respectively. The increase in Diagnostic Imaging revenue was also due to a more favorable product mix sold during the year ended 
December 31, 2015 as compared to the prior year which led to a higher blended average selling price per camera year over year, 
partially offset by attrition in the number of camera maintenance contracts. Consolidated gross profit increased $1.3 million, or 
7.6%, compared to the prior year. The increase in consolidated gross profit is primarily the result of increased overall revenue 
volume as well as improved gross profit as a percentage of revenue in our Diagnostic Imaging business. Our Diagnostic Imaging 
business segment benefited from a more favorable mix of cameras sold during the year ended December 31, 2015 compared to 
the prior year, as well as the release of excess inventory reserves due to the sale of previously reserved inventory. Diagnostic 
Services gross profit decreased for the year ended December 31, 2015 compared to the prior year driven by a decrease in gross 
profit as a percentage of revenue, offset partially by increased revenue. Our total operating expenses increased $1.0 million for 
the year ended December 31, 2015 compared to the prior year, driven by a $1.5 million increase in general and administrative 
expenses  primarily  as  a  result  of  $1.3  million  in  legal  and  professional  services  costs  related  to  the  DMS  Health  acquisition 
completed on January 1, 2016, partially offset by the non-recurrence of $0.7 million in restructuring costs which occurred during 
the year ended December 31, 2014. Our consolidated net income for the year ended December 31, 2015 was $21.6 million, which 
is an increase of $19.2 million compared to our net income of $2.5 million during the prior year, primarily due to an income tax 
benefit of $19.1 million recognized during the year ended December 31, 2015, as we concluded that it was more likely than not 
that a portion of our deferred tax assets would be realized through future taxable income and therefore we released the associated 
valuation allowance related to those tax assets.

 For the year ended December 31, 2015, Diagnostic Services operated 86 nuclear gamma cameras and 61 ultrasound imaging 
systems. We continue to strive to improve our overall profitability through more efficient utilization of our fleet of gamma cameras 
and ultrasound equipment. We measure efficiency by tracking system utilization, which is measured based on the percentage of 
days that our nuclear gamma cameras and ultrasound equipment are used to deliver services to customers out of the total number 
of days that they are available to deliver such services. System utilization decreased to 62% for the year ended December 31, 2015, 
compared to 66% in the prior year, due to an increase in the number of mobile cameras and ultrasound machines in operation, 
partially offset by an increase in the number of days our physician customers utilized our imaging services.  

Critical Accounting Policies

Management’s discussion and analysis of our financial condition and results of operations are based upon our consolidated 
financial statements which are prepared in accordance with United States generally accepted accounting principles. The preparation 
of these financial statements requires us to make estimates and judgments that affect the reported amounts of assets and liabilities, 
related disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues 
and expenses during the reporting period. We evaluate our estimates and judgments, the most critical of which are those related 
to revenue recognition, reserves for contractual allowances and doubtful accounts, inventory valuation, and income taxes. We base 
our estimates and judgments on historical experience and other factors that we believe to be reasonable under the circumstances. 
Materially different results can occur as circumstances change and additional information becomes known.

Revenue Recognition

We  derive  revenues  primarily  from  providing  in-office  services  related  to  the  performance  of  cardiac  diagnostic  imaging 
procedures, cardiac event monitoring, and from selling and servicing solid-state digital gamma cameras. We recognize revenue 
in accordance with the authoritative guidance for revenue recognition, when all of the following four criteria are met: (i) a contract 
or sales arrangement exists; (ii) products have been shipped and title has transferred or services have been rendered; (iii) the price 
of the products or services is fixed or determinable; and (iv) collectability is reasonably assured. The timing of revenue recognition 
is based upon factors such as passage of title and risk of loss, the need for installation, and customer acceptance. These factors are 
based on the specific terms of each contract or sales arrangement.

Diagnostic Services imaging services revenue is derived from our ability to provide our physician customers with our services, 
which includes use of our imaging system, qualified personnel, and related items required to perform imaging in their own offices 
and bill Medicare, Medicaid, and other payors for in-office nuclear and ultrasound diagnostic imaging procedures. Revenue related 
to diagnostic imaging services is recognized at the time services are performed and collection is reasonably assured. Imaging 
24

services are generally billed on a per-day basis under annual contracts for nuclear diagnostic imaging, which specifies the number 
of days of service to be provided, or on a flat rate month-to-month basis for ultrasound imaging.

Our cardiac event monitoring services are provided primarily through an independent diagnostic testing facility model which 
allows us to bill Medicare, Medicaid, or one of the third-party healthcare insurers directly for services provided. We also receive 
reimbursement directly from patients through co-pays and self-pay arrangements. Billings for services reimbursed by third party 
payors, including Medicare, are recorded as revenue net of contractual allowances. Contractual allowances are estimated based 
on historical collections by Current Procedural Terminology (CPT) code for specific payors, or class of payors. Adjustments to 
the estimated receipts, based on final settlement with the third party payors, are recorded upon settlement. 

Diagnostic Imaging product revenues are generated from the sales of gamma cameras and follow-on maintenance service 
contracts. We generally recognize revenue upon delivery and acceptance by customers. We also provide installation and training 
for camera sales in the United States. Installation and initial training is generally performed shortly after delivery and represents 
a cost which we accrue at the time revenue is recognized. Neither service is essential to the functionality of the product. Maintenance 
services are sold beyond the term of the warranty, which is generally one year from the date of purchase. Revenue from these 
contracts is deferred and recognized ratably over the period of the obligation and is included in Diagnostic Imaging sales.

Allowance for Doubtful Accounts and Billing Adjustments 

We provide reserves for doubtful accounts and billing adjustments. We review reserves on a quarterly basis and make adjustments 
based on our historical experience rate and known collectability issues and disputes. We also consider our bad debt write-off and 
billing adjustments history. Our estimates of collectability could be impacted by material amounts due to changed circumstances, 
such as a higher number of defaults or material adverse changes in a payor’s ability to meet its obligations. Within Diagnostic 
Services, we record adjustments and credit memos that represent billing adjustments subsequent to the performance of service. A 
provision for billing adjustments is charged against Diagnostic Services revenues and a provision for doubtful accounts is charged 
to general and administrative expenses. 

Contractual Allowances

Our cardiac event monitoring services are provided primarily through an independent diagnostic testing facility model which 
allows us to bill Medicare, Medicaid, or one of the third-party healthcare insurers directly for services provided. Accounts receivable 
for cardiac event monitoring are recorded at the time revenue is recognized, net of contractual allowances. Contractual allowances 
are estimated based on historical collections by Current Procedural Terminology (CPT) code for specific payors, or class of payors. 
The ultimate collection of accounts receivable may not be known for several months after services have been provided and billed. 
Because of continuing changes in the healthcare industry and third party reimbursement, it is possible that our estimates could 
change, which could have a material impact on our operations and cash flows.

Business Combinations

Under the acquisition method of accounting, we allocate the fair value of the total consideration transferred to the tangible and 
identifiable intangible assets acquired and liabilities assumed based on their estimated fair values on the date of acquisition. The 
fair values assigned, defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction 
between willing market participants, are based on estimates and assumptions determined by management. We record the excess 
consideration over the aggregate fair value of tangible and intangible assets, net of liabilities assumed, as goodwill. These valuations 
require us to make significant estimates and assumptions, especially with respect to intangible assets. 

In connection with certain of our acquisitions, additional contingent consideration is earned by the sellers upon completion of 
certain future performance milestones. In these cases, a liability is recorded on the acquisition date for an estimate of the acquisition 
date fair value of the contingent consideration by applying the income approach utilizing variable inputs such as anticipated future 
cash flows, risk-free adjusted discount rates, and nonperformance risk. Any change in the fair value of the contingent consideration 
subsequent to the acquisition date is recognized as general and administrative expense (income), in our consolidated statements 
of comprehensive income. This method requires significant management judgment, including the probability of achieving certain 
future milestones and discount rates. Future changes in our estimates could result in expenses or gains. 

Management typically uses the discounted cash flow method to value our acquired intangible assets. This method requires 
significant management judgment to forecast future operating results and establish residual growth rates and discount factors. The 
estimates we use to value and amortize intangible assets are consistent with the plans and estimates that we use to manage our 
business and are based on available historical information and industry estimates and averages. If the subsequent actual results 
and updated projections of the underlying business activity change compared with the assumptions and projections used to develop 
these values, we could experience impairment charges. In addition, we have estimated the economic lives of certain acquired 
assets and these lives are used to calculate depreciation and amortization expense. If our estimates of the economic lives change, 
depreciation or amortization expenses could be accelerated or slowed.

25

Inventory

We state inventories at the lower of cost (first-in, first-out) or market (net realizable value) and review our inventory balances 
for excess and obsolete inventory levels on a quarterly basis. Costs include material, labor, and manufacturing overhead and 
variance costs. We rely on historical information to support our reserve and utilize management’s business judgment. Per our 
policy, we generally reserve 100% of the cost of inventory quantities in excess of a defined period of demand. Once inventory is 
reserved, we do not adjust the reserve balance until the inventory is sold or disposed.

Fair Value of Financial Instruments

The authoritative guidance for fair value measurements defines fair value for accounting purposes, establishes a framework 
for measuring fair value, and provides disclosure requirements regarding fair value measurements. The guidance defines fair value 
as an exit price, which is the price that would be received upon sale of an asset or paid upon transfer of a liability in an orderly 
transaction between market participants at the measurement date. The degree of judgment utilized in measuring the fair value of 
assets and liabilities generally correlates to the level of pricing observability. Assets and liabilities with readily available, actively 
quoted prices, or for which fair value can be measured from actively quoted prices in active markets, generally have more pricing 
observability and require less judgment in measuring fair value. Conversely, assets and liabilities that are rarely traded or not 
quoted have less pricing observability, and are generally measured at fair value using valuation models that require more judgment. 
These valuation techniques involve some level of management estimation and judgment, the degree of which is dependent on the 
price transparency of the asset, liability, or market, and the nature of the asset or liability. We have categorized our assets and 
liabilities measured at fair value into a three-level hierarchy in accordance with this guidance. See Note 5 to the audited consolidated 
financial statements for a further discussion regarding our measurement of assets and liabilities at fair value.

Valuation of Long-Lived Assets including Finite Lived Purchased Intangible Assets

Long-lived assets consist of property and equipment and finite lived intangible assets. We record property and equipment at 
cost, and record other intangible assets based on their fair values at the date of acquisition. We calculate depreciation on property 
and equipment using the straight-line method over the estimated useful life of the assets. Charges related to amortization of assets 
recorded under capital leases are included within depreciation expense. We calculate amortization on other intangible assets using 
either the accelerated or the straight-line method over the estimated useful life of the assets, based on the nature of when we expect 
to receive cash inflows generated by the intangible assets.

Impairment losses on long-lived assets used in operations are recorded when indicators of impairment are present and the 
undiscounted cash flows estimated to be generated by those assets are less than the assets’ carrying amount. If such assets are 
considered to be impaired, the impairment to be recognized is measured by the amount by which the carrying amount of the assets 
exceeds the estimated fair value of the assets. When indicators of impairment exist, we perform a review of the carrying value of 
our long-lived assets to be held and used, including certain identifiable intangible assets.  No impairment losses were recorded on 
long-lived assets to be held and used during the years ended December 31, 2015, 2014, or 2013. During the year ended December 31, 
2015, an impairment loss of $56,000 was recorded related to the excess of the carrying amount above fair value of certain assets 
held for sale. No impairment losses were recorded on long-lived assets held for sale during the years ended December 31, 2014, 
or 2013.

Valuation of Goodwill

We  review  goodwill  for  impairment  on  an  annual  basis  during  the  fourth  quarter,  as  well  as  when  events  or  changes  in 
circumstances indicate that the carrying value may not be recoverable. We begin the process by assessing qualitative factors in 
determining whether it is more likely than not that the fair value of our reporting unit is less than its carrying amount. After 
performing the aforementioned assessment and upon review of the results of such assessment, we may begin performing step one 
of the two-step impairment analysis by quantitatively comparing the fair value of the reporting unit to the carrying value of the 
reporting unit, including goodwill. If the carrying value of the reporting unit exceeds the fair value of the reporting unit, then we 
must perform the second step of the impairment test, whereby the carrying value of the reporting unit’s goodwill is compared to 
its implied fair value. If the carrying value of the goodwill exceeds the implied fair value, an impairment loss equal to the difference 
would be recorded. No impairment losses were recorded on goodwill during the years ended December 31, 2015, 2014, or 2013.

Restructuring

Restructuring  costs  are  included  in  income  from  operations  within  the  consolidated  statements  of  comprehensive  income. 
Losses  on  property  and  equipment  are  recorded  consistent  with  our  accounting  policy  related  to  long-lived  assets.  One-time 
termination benefits are recorded at the time they are communicated to the affected employees. Losses on property lease obligations 
are recorded when the lease is abandoned or terminated. 

26

On February 28, 2013, we announced a plan to restructure our Diagnostic Imaging business. In addition, on January 27, 2014, 
we announced a plan to exit our 47,000 square foot former headquarters facility in Poway, California. See Note 11 to the audited 
consolidated financial statements for further detail.

Share-Based Compensation

We grant options to purchase our common stock and restricted stock units (RSUs) to our employees and directors under our 
equity compensation plans. We estimate the fair value of the stock option awards using the Black-Scholes option-pricing model 
on the date of grant. The fair value of RSUs is based on the stock price on the date of grant. The fair value of equity instruments 
that are expected to vest are recognized using the straight-line method over the requisite service period.  We estimate the forfeiture 
rate based on historical data for forfeitures and we are recognizing compensation costs only for those equity awards expected to 
vest. 

Income Taxes 

We provide for income taxes under the liability method. This approach requires the recognition of deferred tax assets and 
liabilities for the expected future tax consequences of differences between the tax basis of assets or liabilities and their carrying 
amounts in the financial statements. We provide a valuation allowance for deferred tax assets if it is more likely than not that these 
items will expire before we are able to realize their benefit. We calculate the valuation allowance in accordance with the authoritative 
guidance relating to income taxes, which requires an assessment of both positive and negative evidence regarding the realizability 
of these deferred tax assets when measuring the need for a valuation allowance. Significant judgment is required in determining 
any valuation allowance against deferred tax assets. As of December 31, 2014, due to a history of operating losses and other key 
operating factors, we concluded that a full valuation allowance was necessary to offset all of our deferred tax assets. A significant 
piece of objective negative evidence evaluated as of December 31, 2014, was the cumulative pretax loss incurred over the three-
year period ended December 31, 2014. During the year ended December 31, 2015, we concluded that it was more likely than not 
that a portion of our deferred tax assets would be realized through future taxable income. This conclusion was based on our 
restructuring efforts in 2013 and 2014 and resulting sustained profitability for the second half of 2013, 2014, and 2015, as well as 
our projections of positive future earnings and other key operating factors. As of September 30, 2015, we had generated cumulative 
pretax income over the preceding twelve quarter period, and therefore the objective negative evidence of a history of operating 
losses was no longer present. The partial release of the valuation allowance associated with our deferred tax assets was the primary 
driver of the income tax benefit of $19.1 million for the year ended December 31, 2015. The release of the valuation allowance 
will not affect the amount of cash paid for income taxes.

We will reassess the ability to realize the deferred tax assets on a quarterly basis. If it is more likely than not that we will not 
realize the recognized deferred tax assets, then all or a portion of the valuation allowance may need to be re-established, which 
would result in a charge to tax expense. Conversely, if new events indicate that it is more likely than not that we will realize 
additional deferred tax assets, then all or a portion of the remaining valuation allowance may be released, which would result in 
a tax benefit.

Comparison of Years Ended December 31, 2015 and 2014 

Revenues

Consolidated. Consolidated revenue was $60.8 million for the year ended December 31, 2015, an increase of $5.2 million, or 
9.4%, from the prior year, driven by a $4.2 million, or 10.0%, increase in our Diagnostic Services revenue year over year. The 
increase in Diagnostic Services revenue is primarily due to $2.6 million of incremental revenue associated with the MD Office 
acquisition, which occurred on March 5, 2015, as well as $1.6 million of incremental cardiac event monitoring revenue resulting 
from the Telerhythmics acquisition, which occurred on March 13, 2014. Diagnostic Imaging segment revenues for the year ended 
December 31, 2015 increased by $1.0 million, or 7.3%, compared to the prior year, primarily due to an increase in the volume of 
cameras sold, as well as a more favorable product mix during the year ended December 31, 2015 as compared to the prior year, 
which led to a higher blended average selling price per camera year over year. Diagnostic Services revenue accounted for 76.3% 
of total revenues for the year ended December 31, 2015, compared to 75.8% for the prior year. We expect consolidated revenue 
to increase significantly in 2016 compared to 2015 as a result of the DMS Health acquisition.

Diagnostic Services. Our Diagnostic Services revenue was $46.4 million for the year ended December 31, 2015, an increase 
of $4.2 million, or 10.0%, from the prior year. The increase in Diagnostic Services revenue is primarily due to $2.6 million of 
incremental revenue associated with the MD Office acquisition, which occurred on March 5, 2015, as well as $1.6 million of 
incremental cardiac event monitoring revenue resulting from the Telerhythmics acquisition, which occurred on March 13, 2014. 
Excluding the impact of acquisitions, revenue in the Diagnostic Services business increased slightly compared to the prior year 
driven by an increase in the number of days our physician customers utilized our imaging services, partially offset by a decrease 
in our average mobile imaging rate per day and a decrease in ancillary revenue from short-term equipment rentals.

Diagnostic Imaging. Our Diagnostic Imaging revenue was $14.4 million for the year ended December 31, 2015, an increase 
of $1.0 million, or 7.3%, compared to the prior year, primarily due to an increase in the volume of cameras sold, as well as a more 
favorable product mix sold during the year ended December 31, 2015 as compared to the prior year which led to a higher blended 
average selling price per camera period over period, partially offset by attrition in the number of camera maintenance contracts. 
The number of cameras sold increased to 31 from 27 during the years ended December 31, 2015 and 2014, respectively, as a result 
of overall improved market conditions. 

Cost of Revenue and Gross Profit

Consolidated. Consolidated gross profit was $17.9 million for the year ended December 31, 2015, an increase of $1.3 million, 
or 7.6%, compared to the prior year. The increase in consolidated gross profit is primarily the result of increased overall revenue 
volume as well as improved gross profit as a percentage of revenue in our Diagnostic Imaging business. Our Diagnostic Imaging 
business segment benefited from a more favorable mix of cameras sold during the year ended December 31, 2015 compared to 
the prior year, as well as a release of excess inventory reserves due to the sale of previously reserved inventory. Diagnostic Services 
gross profit decreased slightly for the year ended December 31, 2015 driven by a decrease in gross profit as a percentage of revenue, 
offset partially by increased revenue. Consolidated gross profit as a percentage of revenue decreased to 29.4% for the year ended 
December 31, 2015 from 29.9% for the prior year, driven by unfavorability in our Diagnostic Services business offset partially 
by favorability in our Diagnostic Imaging business. We expect consolidated cost of revenue and gross profit to increase significantly 
in 2016 compared to 2015 as a result of the DMS Health acquisition.

Diagnostic Services. Cost of Diagnostic Services revenue consists of labor, radiopharmaceuticals, equipment depreciation, and 
other costs associated with providing our services. Cost of Diagnostic Services revenue was $36.0 million for the year ended 
December 31, 2015, an increase of $4.2 million, or 13.4%, from the prior year. The increase in cost of Diagnostic Services revenue 
is primarily a result of the provision of incremental cardiac event monitoring services associated with the Telerhythmics acquisition, 
and an increased amount of imaging days provided, driven in part by the MD Office acquisition. Diagnostic Services gross profit 
was $10.4 million for the year ended December 31, 2015, a decrease of $10 thousand, or 0.1%, as compared to the prior year 
primarily as a result of decreased gross profit percentage of revenue offset partially by increased revenue volume. Diagnostic 
Services gross profit as a percentage of Diagnostic Services revenue decreased to 22.5% for the year ended December 31, 2015 
from 24.8% in the prior year. The decrease in gross profit as a percentage of revenue was attributable to a decrease in the average 
mobile imaging rate per day with the associated service costs remaining relatively consistent, as well as decreased revenue and 
gross profit contribution from short-term equipment rentals and ancillary services.

Diagnostic Imaging. Cost of Diagnostic Imaging revenue primarily consists of materials, labor, and overhead costs associated 
with the manufacturing, warranty, and service contracts associated with our products. Cost of Diagnostic Imaging revenues was 
$6.9 million for the year ended December 31, 2015, a decrease of $0.3 million, or 4.1%, over the prior year, primarily as a result 
of a $0.3 million increase in the release of excess inventory reserves due to the sale of previously reserved inventory during the 
year ended December 31, 2015 compared to the prior year. Diagnostic Imaging gross profit was $7.5 million for the year ended 
December 31, 2015, an increase of $1.3 million, or 20.7%, as compared to the prior year due to a greater volume and more favorable 
mix of camera sales, as well as the release of excess inventory reserves due to the sale of previously reserved inventory. Diagnostic 

29

Imaging gross profit as a percentage of Diagnostic Imaging revenue increased to 51.8% for the year ended December 31, 2015 
from 46.1% for the prior year primarily due to a more favorable mix of camera sales and the release of excess inventory reserves 
related to the sale of previously reserved inventory. During 2015, we recognized a benefit within cost of sales for Diagnostic 
Imaging of $1.0 million associated with the release of excess inventory reserves related to the sale of previously reserved inventory. 
Though the accrual and release of inventory reserves is part of a normal manufacturing operation, we believe that the releases 
benefiting cost of sales will largely not occur in future years, impacting our margin in Diagnostic Imaging in future years compared 
to 2015.

Operating Expenses

Marketing and Sales. Marketing and sales expenses consist primarily of salaries, commissions, bonuses, recruiting costs, travel, 
marketing materials, and trade show costs. Marketing and sales expenses were $4.7 million for the year ended December 31, 2015, 
an increase of $11 thousand, or 0.2%, compared to the prior year, primarily as a result of increased investment in sales and marketing 
resources associated with the Telerhythmics business, offset partially by decreased variable compensation. Marketing and sales 
expenses as a percentage of total revenues were 7.8% and 8.5% for the years ended December 31, 2015 and 2014, respectively. 
We  expect  marketing  and  sales  expenses  to  increase  significantly  in  2016  compared  to  2015  as  a  result  of  the  DMS  Health 
acquisition.

General  and Administrative. General  and  administrative  expenses  consist  primarily  of  salaries  and  other  related  costs  for 
accounting, human resources, information technology, and executive personnel, legal related costs, professional fees, outside 
services, insurance, and costs related to our board of directors. General and administrative expenses were $9.9 million for the year 
ended December 31, 2015, an increase of $1.5 million, or 18.5%, compared to the prior year, primarily as a result of $1.3 million 
of legal and professional services costs related to the DMS Health acquisition and increased costs related to the administration of 
the Telerhythmics business, partially offset by decreased variable compensation. General and administrative expenses were 16.3% 
of total revenue for the year ended December 31, 2015 compared to 15.0% for the prior year. We expect general and administrative 
expenses to increase significantly in 2016 compared to 2015 as a result of the DMS Health acquisition.

Restructuring. On January 27, 2014, we announced a plan to exit our 47,000 square foot former headquarters facility in Poway, 
California (the Facilities restructuring initiative). This action was undertaken as the facility had excess space and capacity given 
our current operating plan. We entered into a termination agreement to end the lease on the facility as of April 30, 2014. The 
original term of the lease would have continued through February 29, 2016. Concurrently with the termination of the lease for the 
47,000 square foot Poway, California facility, we entered into a new lease agreement for a separate 21,300 square foot facility to 
house our Diagnostic Imaging operations. As a result of the Facilities restructuring initiative, we incurred a total of $0.7 million 
of restructuring charges, all of which were incurred during the year ended December 31, 2014. No restructuring initiatives were 
instituted in fiscal year 2015. 

Other Income (Expense), Net

Consolidated. Other income (expense) consists primarily of interest income and expense and other non-operating expenses. 
Other expense was $0.3 million for the year ended December 31, 2015, an increase of $0.3 million compared to the prior year. 
The increase was due to an impairment loss of $0.2 million recognized in the year ended December 31, 2015 on our investment 
in Perma-Fix Medical, S.A. (Perma-Fix Medical). See note 12 to the consolidated financial statements for further information.

Income Tax Benefit (Expense)

Consolidated.  Income  tax  benefit  was  $19.1  million  for  the  year  ended  December 31,  2015,  an  increase  of  $19.2  million 
compared to the prior year due to the release of the valuation allowance associated with a portion of our deferred tax assets. During 
the year ended December 31, 2015, we concluded that it was more likely than not that a portion of our deferred tax assets would 
be realized through future taxable income. This conclusion was based on our restructuring efforts in 2013 and 2014 and resulting 
sustained profitability for the second half of 2013, 2014, and 2015, as well as our projections of positive future earnings and other 
key operating factors. As of September 30, 2015, we had generated cumulative pretax income over the preceding twelve quarter 
period, and therefore the objective negative evidence of a history of operating losses was no longer present. 

Further, during the year ended December 31, 2015, we recorded an income tax benefit of approximately $0.5 million related 
to the release of the valuation allowance associated with the acquisition of MD Office. The valuation allowance occurred when 
we recorded an increase to our deferred tax liability balance as a result of book and tax basis differences in acquired fixed, intangible, 
and other assets of MD Office. 

We will reassess our ability to realize the deferred tax assets on a quarterly basis. If it is more likely than not that we will not 
realize the recognized deferred tax assets, then all or a portion of the valuation allowance may need to be re-established, which 
would result in a charge to income tax expense. Conversely if new events indicate that it is more likely than not that we will realize 
additional deferred tax assets, then all or a portion of the remaining valuation allowance may be released, which would result in 

30

a tax benefit. An acquisition that occurs in future periods will cause our conclusions to be reassessed in the period of the acquisition 
depending on the size and scope of the acquisition.

Comparison of Years Ended December 31, 2014 and 2013 

Revenues

Consolidated. Consolidated revenue was $55.6 million for the year ended December 31, 2014, an increase of $6.2 million, or 
12.6%, from the prior year, driven by a $5.0 million, or 13.4%, increase in our Diagnostic Services revenue year over year. The 
increase in Diagnostic Services revenue is primarily due to $3.9 million of  incremental cardiac event monitoring revenue resulting 
from the Telerhythmics acquisition, which occurred on March 13, 2014. The remaining increase in Diagnostic Services revenue 
for the year ended December 31, 2014 compared to the prior year is due to a greater number of imaging days provided, offset 
partially by a decrease in the average mobile imaging rate per day. Diagnostic Imaging revenue increased $1.2 million, or 10.1%, 
compared to the prior year, as a result of a greater volume of camera units sold during the year ended December 31, 2014 compared 
to  the  prior  year.  Diagnostic  Services  revenue  accounted  for 75.8% of  total  revenues  for  the  year  ended December 31,  2014, 
compared to 75.3% for the prior year. We expect Diagnostic Services revenue to continue to represent the larger percentage of 
our consolidated revenue.

Diagnostic Services. Our Diagnostic Services revenue was $42.2 million for the year ended December 31, 2014, an increase 
of $5.0 million, or 13.4%, from the prior year.  The primary driver of the increase is the Telerhythmics acquisition, which occurred 
on  March  13,  2014,  and  contributed  $3.9  million  of  incremental  cardiac  event  monitoring  revenue  during  the  year  ended 
December 31, 2014. The remaining increase in Diagnostic Services revenue for the year ended December 31, 2014 compared to 
the prior year was due to a greater number of imaging days provided, as well as greater ancillary revenue from short-term equipment 
rentals, offset partially by a decrease in the average mobile imaging rate per day.

Diagnostic Imaging. Our Diagnostic Imaging revenue was $13.4 million for the year ended December 31, 2014, an increase 
of $1.2 million, or 10.1%, compared to the prior year, primarily due to an increase in the volume of cameras sold, offset partially 
by attrition in the number of associated camera maintenance contracts. The number of cameras sold increased to 27 from 20 during 
the years ended December 31, 2014 and 2013, respectively, as a result of additional sales resources and overall improved market 
conditions. Further, a more favorable product mix was sold during the year ended December 31, 2014 as compared to the prior 
year, which led to a higher blended average selling price per camera year over year.

Cost of Revenue and Gross Profit

Consolidated. Consolidated gross profit was $16.6 million for the year ended December 31, 2014, an increase of $2.5 million, 
or 17.9%, compared to the prior year. The increase in consolidated gross profit is primarily the result of increased overall revenue 
volume, as well as improved gross profit as a percentage of revenue in our Diagnostic Imaging business. Our Diagnostic Imaging 
business segment benefited from the release of excess inventory reserves due to the sale of previously reserved inventory, as well 
as reduced manufacturing and overhead costs for the year ended December 31, 2014, compared to the prior year. Consolidated 
gross profit as a percentage of revenue increased to 29.9% for the year ended December 31, 2014 from 28.6% for the prior year.

Diagnostic Services. Cost of Diagnostic Services revenue was $31.7 million for the year ended December 31, 2014,  an increase 
of $3.9 million, or 14.0%, from the prior year. The increase in cost of Diagnostic Services revenue is primarily the result of the 
provision of incremental cardiac event monitoring services associated with the Telerhythmics acquisition, as well as an increased 
amount of imaging days provided. Diagnostic Services gross profit was $10.4 million for the year ended December 31, 2014, an 
increase of $1.1 million, or 11.8%, as compared to the prior year primarily as a result of increased revenue year over year. Diagnostic 
Services gross profit as a percentage of Diagnostic Services revenue decreased to 24.8% for the year ended December 31, 2014 
from 25.1% in the prior year. The decrease in gross profit as a percentage of revenue was attributable to a decrease in the average 
mobile imaging rate per day with the associated service costs remaining relatively consistent, as well as first year integration 
efforts and costs associated with the Telerhythmics acquisition, partially offset by favorable gross profit contribution from short-
term equipment rentals.

Diagnostic Imaging. Cost of Diagnostic Imaging revenues was $7.2 million for the year ended December 31, 2014, a decrease 
of $0.2 million, or 2.5%, over the prior year primarily as a result of a net $0.6 million release of excess inventory reserves due to 
the sale of previously reserved inventory during the year ended December 31, 2014, as well as reduced manufacturing and overhead 
costs. Diagnostic Imaging gross profit was $6.2 million for the year ended December 31, 2014, an increase of $1.4 million, or 
29.7%, as compared to the prior year due to a greater volume of camera sales, and the release of excess inventory reserves due to 
the sale of previously reserved inventory, as well as reduced manufacturing and overhead costs. Diagnostic Imaging gross profit 
as a percentage of Diagnostic Imaging revenue increased to 46.1% for the year ended December 31, 2014 from 39.1% for the 
prior year primarily due to reduced excess and obsolete inventory costs, reduced manufacturing and overhead costs, and a more 
favorable product mix for cameras.

31

Operating Expenses

Research and Development.  Research and development expenses were the costs associated with the design, development, and 
expansion of our existing technology, and consist of salaries, developmental material costs, facility and overhead costs, consulting 
fees, and non-recurring engineering costs. There were no research and development expenses for the year ended December 31, 
2014, representing a decrease of $1.0 million, or 100.0%, compared to the prior year. The decrease is due to our Diagnostic Imaging 
restructuring initiative, which focused on our existing camera product offerings rather than continued development of new product 
offerings with alternative applications. We believe our current product line has a technological advantage over competing products 
and continued relevance well into the future. On a go forward basis, we plan to primarily utilize outside service providers for 
research  and  development  services  on  an  as  needed  basis  for  updates  and  enhancements,  with  the  amount  of  corresponding 
expenditure fluctuating commensurately quarter by quarter. Research and development expenses were 0% and 8.4% of Diagnostic 
Imaging revenue for the years ended December 31, 2014 and 2013, respectively. 

Marketing and Sales.  Marketing and sales expenses were $4.7 million for the year ended December 31, 2014, an increase of 
$0.3 million, or 7.2%, compared to the prior year, primarily as a result of increased sales resources associated with the Telerhythmics 
business, as well as additional investment in Diagnostic Imaging sales resources, offset partially by reduced marketing costs 
associated with new and developmental product offerings. Marketing and sales expenses as a percentage of total revenues were 
8.5% and 8.9% for the years ended December 31, 2014 and 2013, respectively.

General and Administrative. General and administrative expenses were $8.3 million for the year ended December 31, 2014, 
an increase of $0.2 million, or 2.8%, compared to the prior year, primarily as a result of increased costs related to the administration 
of Telerhythmics business, partially offset by less cost associated with our 2014 annual shareholder meeting compared to the $0.7 
million of  legal  costs  incurred  in  the  year  ended  December 31,  2013  related  to the  2013  proxy  contest  and  subsequent  legal 
proceedings associated with the proxy contest. General and administrative expenses were 15.0% of total revenue for the year 
ended December 31, 2014 compared to 16.4% for the prior year. 

Restructuring. On February 28, 2013, we announced a plan to restructure our Diagnostic Imaging business to significantly 
reduce costs, including a reduction in force (the Diagnostic Imaging restructuring initiative). The Diagnostic Imaging restructuring 
initiative was completed as of June 30, 2014. A total of $1.8 million of costs were incurred related to the Diagnostic Imaging 
restructuring initiative, with $29 thousand incurred in the year ended December 31, 2014 and $1.7 million incurred in the year 
ended December 31, 2013.

On January 27, 2014, we announced a plan to exit our 47,000 square foot former headquarter facility in Poway, California (the 
Facilities restructuring initiative). This action was undertaken as the facility had excess space and capacity given our current 
operating plan. We entered into a termination agreement to end the lease on the facility as of April 30, 2014. The original term of 
the lease would have continued through February 29, 2016. Concurrently with the termination of the lease for the 47,000 square 
foot Poway, California facility, we entered into a new lease agreement for a separate 21,300 square foot facility to house our 
Diagnostic Imaging operations. As a result of the Facilities restructuring initiative, we incurred a total of $0.7 million of restructuring 
charges, all of which were incurred during the year ended December 31, 2014. All restructuring efforts associated with this initiative 
were completed as of December 31, 2014.

Gain on sale of assets and license agreement. On July 31, 2013, we entered into an asset purchase agreement with Novadaq 
Technologies Inc. (Novadaq). Under the terms of the asset purchase agreement, we sold Novadaq all of our assets specifically 
related to an uncommercialized surgical imaging system previously in development. We also licensed certain existing Company 
technology to Novadaq for their use in the peri-operative field. In exchange, we received upfront consideration of $2.0 million, 
and  could  receive  up  to  $1.0  million  in  deferred  contingent  payments  based  on  the  achievement  of  specific  regulatory  and 
commercial  milestones  as  well  as  a  royalty  on  sales,  if  any. A  gain  of  $1.6  million  representing  the  $2.0  million  of  upfront 
consideration less legal, consulting, and other transaction fees, as well as the cost basis of the inventory, was recorded during the 
year ended December 31, 2013. The sale of the technology is consistent with our focus on our existing camera product offerings, 
rather than development of completely new product offerings.

Liquidity and Capital Resources

Overview

We generated $3.7 million of positive cash flow from operations during the year ended December 31, 2015, and expect to 
continue to generate positive cash flow from operations on an annual basis in the future. Cash flows from operations primarily 
represent inflows from net income (adjusted for depreciation, amortization, and other non-cash items), as well as the net effect of 
changes in working capital. Cash flows from investing activities primarily represent our investment in capital equipment required 
to grow our business, as well as acquisition and divestiture activity. Cash flows from financing activities primarily represent 
outflows related to dividend payments and share repurchases, offset by the receipt of cash related to the exercise of stock options. 

32

Our principal sources of liquidity are our existing cash and cash equivalents, short-term investments, and cash generated from 
operations. As of December 31, 2015, we had cash and cash equivalents of $15.9 million. We generally invest our cash reserves 
in money market funds, U.S. treasury, and corporate debt securities. In regards to additional sources of financing, we currently 
have available a shelf registration statement on Form S-3 that provides us with increased capital flexibility to pursue corporate 
objectives by allowing us to offer and sell up to $20.0 million of securities. 

In connection with the acquisition of DMS Health, which occurred on January 1, 2016, we entered into a five year credit facility 
(maturing in January 2021) with Wells Fargo pursuant to which Wells Fargo provided the Company with a senior secured credit 
facility in the aggregate amount of up to $40 million. On January 4, 2016, we drew down $33.6 million against the Credit Facility 
to fund the acquisition of DMS Health. Beginning in 2016, the Credit Facility will require both principal and interest payments 
on a monthly basis, which we expect to fund from our operating cash flow.

We  require  capital  principally  for  capital  expenditures,  acquisition  activity,  dividend  payments,  and  to  finance  accounts 
receivable and inventory. In 2016, we will be required to make both principal and interest payments on the Wells Fargo Credit 
Facility. Our working capital requirements vary from period to period depending on inventory requirements, the timing of deliveries, 
and  the  payment  cycles  of  our  customers.  Our  capital  expenditures  consist  primarily  of  nuclear  cameras,  cardiac  monitoring 
devices, ultrasound machines, vans, and computer hardware and software. Based upon our current level of expenditures and cash 
requirements, we believe our current working capital, together with cash flows from operating activities, will be more than adequate 
to meet our anticipated cash requirements for at least the next 12 months. 

Cash Flows

The following table shows cash flow information for the years ended December 31, 2015, 2014, and 2013 (in thousands):

Net cash provided by operating activities decreased by $0.6 million for the year ended December 31, 2015 compared to the 
prior year. The decrease is attributable to unfavorable changes in working capital primarily related to increases in accounts receivable 
and inventory and decreases in accounts payable and accrued compensation, with income before income taxes remaining relatively 
consistent for the year ended December 31, 2015 compared to the prior year.

Net cash provided by operating activities increased by $2.1 million for the year ended December 31, 2014 compared to the 
prior year. The increase was primarily attributable to net income of $2.5 million generated in fiscal year 2014, an increase of $2.2 
million compared to net income of $0.3 million for fiscal year 2013 driven by increased revenue, improved gross profit, and 
relatively consistent operating expenses.

Investing Activities

Net cash provided by investing activities increased by $7.3 million for the year ended December 31, 2015 compared to net 
cash used in the prior year. This increase was primarily attributable to increased cash provided by maturities of available-for-sale 
securities in the year ended December 31, 2015, compared to the outlay of $3.4 million of cash to acquire Telerhythmics in the 
year ended December 31, 2014, as well as $2.6 million in purchases of available-for-securities in the year ended December 31, 
2014.

Net cash used in investing activities increased by $5.8 million for the year ended December 31, 2014 compared to the prior 
year. The increase was primarily attributable to the outlay of $3.4 million of cash to acquire Telerhythmics in the year ended 
December 31, 2014, compared to approximately $1.7 million of net proceeds received in the prior year from the sale of assets 
related to an uncommercialized surgical imaging system and associated license agreement.

Financing Activities

Net cash used in financing activities increased by $0.2 million for the year ended December 31, 2015 compared to the prior 
year. This increase was primarily attributable to $0.3 million in loan issuance costs related to the acquisition of DMS Health 
completed on January 1, 2016, as well as $3.8 million of dividend payments during the year ended December 31, 2015, compared 
to $3.7 million during the year ended December 31, 2014, and increased repayments of capital lease obligations. The increase in 

33

 
 
cash used was partially offset by increased cash received during the year ended December 31, 2015 related to stock option exercises 
compared to the prior year. 

Net cash used in financing activities increased by $0.2 million for the year ended December 31, 2014 compared to the prior 
year. This increase was primarily attributable to $3.7 million of dividend payments during the year ended December 31, 2014, 
compared  to  $0.9  million  during  the  year  ended  December 31,  2013,  as  well  as  less  cash  received  during  the  year  ended 
December 31, 2014 related to stock option exercises compared to the prior year. Offsetting the increase in cash used in financing 
activities for the year ended December 31, 2014 compared to the prior year were decreased share repurchases, with no share 
repurchases during the year ended December 31, 2014, compared to $3.6 million of cash used for share repurchases in the prior 
year.

Off-Balance Sheet Arrangements

As part of our ongoing business, we do not participate in transactions that generate relationships with unconsolidated entities 
or financial partnerships, such as entities often referred to as structured finance or special purpose entities, or SPEs, which would 
have  been  established  for  the  purpose  of  facilitating  off-balance  sheet  arrangements  or  other  contractually  narrow  or  limited 
purposes. As of December 31, 2015, we were not involved in any unconsolidated SPE transactions.

Contractual Obligations

We are committed to making future cash payments on capital leases (including interest) and operating leases. We have not 
guaranteed the debt of any other party. The following table summarizes our contractual obligations as of December 31, 2015

ITEM 7A. 

QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Interest Rate Risk - Debt Securities. Our exposure to market risk due to changes in interest rates relates primarily to the 
increase or decrease in the value of debt securities in our investment portfolio. Our risk associated with fluctuating interest rates 
is limited to our investments in interest rate sensitive financial instruments. Under our current policies, we do not use interest rate 
derivative instruments to manage exposure to interest rate changes. We attempt to increase the safety and preservation of our 
invested principal funds by limiting default risk, market risk, and reinvestment risk. We mitigate default risk by investing in 
investment grade securities. A 100 basis point adverse move in interest rates along the entire interest rate yield curve would not 
materially affect the fair value of our interest sensitive financial instruments. Changes in interest rates over time will increase or 
decrease our interest income.

Equity Price Risk. We own common shares of Perma-Fix Medical, a publicly traded company listed on the NewConnect 
market of the Warsaw Stock Exchange, that are subject to equity price risk. A 10% decrease in the market price of these equity 
securities would have caused a decrease in the carrying amount of these securities of $49,000.  At December 31, 2015, the gross 
unrealized loss related to these equity securities was $230,000.  Although we consider the unrealized loss to be temporary, there 
is a risk that we may incur other-than-temporary impairment charges or realized losses on the value of these securities if they do 
not recover in value within a reasonable period.

Board of Directors and Stockholders
Digirad Corporation

We have audited the accompanying consolidated balance sheet of Digirad Corporation (“Company”) as of December 31, 2015 
and the related consolidated statements of comprehensive income, stockholders’ equity, and cash flows for the year then ended. 
These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on 
these financial statements based on our audit.

We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States). 
Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements 
are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures 
in the financial statements, assessing the accounting principles used and significant estimates made by management, as well as 
evaluating the overall financial statement presentation. We believe that our audit provides a reasonable basis for our opinion.

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial 
position of Digirad Corporation at December 31, 2015, and the results of its operations and its cash flows for the year then ended, 
in conformity with accounting principles generally accepted in the United States of America.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), 
Digirad Corporation's internal control over financial reporting as of December 31, 2015, based on criteria established in Internal

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Board of Directors and Stockholders of Digirad Corporation

We have audited the accompanying consolidated balance sheet of Digirad Corporation as of December 31, 2014, and the related 
consolidated statements of comprehensive income, stockholders’ equity, and cash flows for each of the two years in the period 
ended December 31, 2014. These financial statements are the responsibility of the Company’s management. Our responsibility is 
to express an opinion on these financial statements based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). 
Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements 
are free of material misstatement. We were not engaged to perform an audit of the Company's internal control over financial 
reporting. Our audits included consideration of internal control over financial reporting as a basis for designing audit procedures 
that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Company's 
internal control over financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a test 
basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and 
significant estimates made by management, and evaluating the overall financial statement presentation. We believe that our audits 
provide a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in all material respects, the consolidated financial 
position of Digirad Corporation at December 31, 2014, and the consolidated results of its operations and its cash flows for each 
of the two years in the period ended December 31, 2014, in conformity with U.S. generally accepted accounting principles.

NOTES TO AUDITED CONSOLIDATED FINANCIAL STATEMENTS

NOTE 1. 

The Company

Digirad Corporation (Digirad), a Delaware corporation, is one of the largest national providers of in-office nuclear cardiology 
imaging and ultrasound services, and also provides cardiac event monitoring services. These services are provided to physician 
practices, hospitals, and imaging centers through our Diagnostic Services reportable segment. Digirad also sells solid-state gamma 
cameras for nuclear cardiology and general nuclear medicine applications, as well as provides service on the products sold, through 
our Diagnostic Imaging reportable segment. These two reportable segments, Diagnostic Services and Diagnostic Imaging, are 
collectively referred to herein as the “Company.” 

The accompanying consolidated financial statements include the operations of both segments. Intercompany accounts and 
transactions are accounted for at cost and have been eliminated in consolidation. All our long-lived assets are located in the United 
States and substantially all of our revenues arise from sales activity in the United States.

NOTE 2. 

Basis of Presentation and Significant Accounting Policies

Basis of Presentation

The consolidated financial statements are prepared in conformity with United States generally accepted accounting principles 
(GAAP) and include the financial statements of the Company and its wholly owned subsidiaries. GAAP requires management to 
make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and 
liabilities, and the reported amounts of revenues and expenses. By their nature, estimates are subject to an inherent degree of 
uncertainty. Actual results could differ from management’s estimates. All significant intercompany accounts and transactions have 
been eliminated. Certain reclassifications have been made to the prior period financial statements to conform to the current period 
presentation.

The  financial  results  for  the  year  ended  December 31,  2015  include  the  financial  results  of  MD  Office  Solutions  and 
Telerhythmics, LLC.  See Note 3 to the audited consolidated financial statements for more information related to the acquisitions 
of MD Office Solutions and Telerhythmics, LLC.

Revenue Recognition

We  derive  revenues  primarily  from  providing  in-office  services  related  to  the  performance  of  cardiac  diagnostic  imaging 
procedures, cardiac event monitoring, and from selling and servicing solid-state digital gamma cameras. We recognize revenue 
in accordance with the authoritative guidance for revenue recognition, when all of the following four criteria are met: (i) a contract 
or sales arrangement exists; (ii) products have been shipped and title has transferred or services have been rendered; (iii) the price 
of the products or services is fixed or determinable; and (iv) collectability is reasonably assured. The timing of revenue recognition 
is based upon factors such as passage of title and risk of loss, the need for installation, and customer acceptance. These factors are 
based on the specific terms of each contract or sales arrangement.

Diagnostic Services imaging services revenue is derived from our ability to provide our physician customers with our services, 
which includes use of our imaging system, qualified personnel, and related items required to perform imaging in their own offices 
and bill Medicare, Medicaid, and other payors for in-office nuclear and ultrasound diagnostic imaging procedures. Revenue related 
to diagnostic imaging services is recognized at the time services are performed and collection is reasonably assured. Imaging 
services are generally billed on a per-day basis under annual contracts for nuclear diagnostic imaging, which specifies the number 
of days of service to be provided, or on a flat rate month-to-month basis for ultrasound imaging.

Our cardiac event monitoring services are provided primarily through an independent diagnostic testing facility model which 
allows us to bill Medicare, Medicaid, or one of the third-party healthcare insurers directly for services provided. We also receive 
reimbursement directly from patients through co-pays and self-pay arrangements. Billings for services reimbursed by third party 
payors, including Medicare, are recorded as revenue net of contractual allowances. Contractual allowances are estimated based 
on historical collections by Current Procedural Terminology (CPT) code for specific payors, or class of payors. Adjustments to 
the estimated receipts, based on final settlement with the third party payors, are recorded upon settlement.  

Diagnostic Imaging product revenues are generated from the sales of gamma cameras and follow-on maintenance service 
contracts. We generally recognize revenue upon delivery and acceptance by customers. We also provide installation and training 
for camera sales in the United States. Installation and initial training is generally performed shortly after delivery and represents 
a cost which we accrue at the time revenue is recognized. Neither service is essential to the functionality of the product. Maintenance 
services are sold beyond the term of the warranty, which is generally one year from the date of purchase. Revenue from these 
contracts is deferred and recognized ratably over the period of the obligation and is included in Diagnostic Imaging sales.

Multiple Element Arrangements

In fiscal year 2013, we sold all of our assets specifically related to an uncommercialized surgical imaging system previously 
in development, as well as licensed certain existing Company technology. The transaction was accounted for in accordance with 
the authoritative guidance for multiple element arrangements. We identified the deliverables at the inception of the agreement and 
determined which items had value to the customer on a standalone basis, and were therefore separate units of accounting. Non-
contingent arrangement consideration was allocated at the inception of the agreement to all identified units of accounting based 
on their relative selling price. The relative selling price for each unit of accounting was determined using best estimate of selling 
price, because neither vendor specific objective evidence (VSOE) of selling price nor third-party evidence of selling price existed 
for  the  units  of  accounting. The  non-contingent  amount  of  arrangement  consideration  allocated  to  each  unit  of  account  was 
recognized upon performance and delivery of the related unit of accounting. 

Use of Estimates

The preparation of financial statements in conformity with U.S. generally accepted accounting principles requires management 
to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and disclosures made 
in the accompanying notes to the consolidated financial statements. Significant estimates and judgments include those related to 
revenue recognition, reserves for doubtful accounts and contractual allowances, inventory valuation, and income taxes. Actual 
results could differ from those estimates.

Concentration of Credit Risk and Significant Customers

Financial instruments, which potentially subject us to concentrations of credit risk, consist primarily of cash and cash equivalents,  
investments, and accounts receivable. We limit our exposure to credit loss by generally placing our cash and investments in high 
credit quality financial institutions and investment grade corporate debt securities. Additionally, we have established guidelines 
regarding diversification of our investments and their maturities, which are designed to maintain principal and maximize liquidity. 
For the years ended December 31, 2015 and 2014, Emory Healthcare represented 10.2% and 10.9% of our consolidated revenues, 
respectively, and 13.4% an 14.3% of our Diagnostic Services revenues, respectively.  Prior to 2014, no single customer exceeded 
10% of our consolidated revenues. We believe we have good relations with Emory Healthcare, however, if we were to lose Emory 
Healthcare as a customer, it would likely have a material adverse affect on our operations.  

Fair Value of Financial Instruments

The authoritative guidance for fair value measurements defines fair value for accounting purposes, establishes a framework 
for measuring fair value, and provides disclosure requirements regarding fair value measurements. The guidance defines fair value 
as an exit price, which is the price that would be received upon sale of an asset or paid upon transfer of a liability in an orderly 
transaction between market participants at the measurement date. The degree of judgment utilized in measuring the fair value of 
assets and liabilities generally correlates to the level of pricing observability. Our financial instruments primarily consist of cash 
equivalents, securities available-for-sale, accounts receivable, other current assets, restricted cash, accounts payable, contingent 
consideration, and other current liabilities. The carrying amount of these financial instruments generally approximate fair value 
due to their short term nature. Securities available-for-sale are recorded at fair value.

Cash and Cash Equivalents

We consider all investments with a maturity of three months or less when acquired to be cash equivalents. 

Securities Available-for-Sale

Securities available-for-sale primarily consist of investment grade corporate debt securities. In addition, we own shares of 
common stock issued by Perma-Fix Medical, S.A. (Perma-Fix Medical), a publicly traded company listed on the NewConnect 
market of the Warsaw Stock Exchange. We classify all debt securities as available-for-sale and as current assets, as the sale of 
such securities may be required prior to maturity to execute management strategies. The Perma-Fix Medical equity securities are 
classified as an other asset (non-current), as the investment is strategic in nature and our current intent is to hold the investment 
over a several year period. Securities available-for-sale are carried at fair value, with the unrealized gains and losses reported as 
a component of accumulated other comprehensive loss in stockholders' equity until realized. Realized gains and losses from the 
sale of available-for-sale securities, if any, are determined on a specific identification basis. A decline in the market value of any 
available-for-sale security below cost that is determined to be other than temporary will result in an impairment charge to earnings 
and a new cost basis for the security is established. No such impairment charges were recorded for any period presented. It is not 
more likely than not that we will be required to sell investments before recovery of their amortized costs. Premiums and discounts 
are amortized or accreted over the life of the related security as an adjustment to yield using the straight-line method and included 
in interest income. Interest income is recognized when earned. Realized gains and losses on investments in securities are included 
in other income (expense) within the consolidated statements of comprehensive income. We recognized a loss of $233,000 related 

42

to available-for-sale securities for the year ended December 31, 2015 due to the initial excess of the transaction price over fair 
value for the Perma-Fix Medical investment. The realized gains and losses related to securities available-for-sale were minimal 
for the years ended December 31, 2014 and 2013.

The following table sets forth the composition of securities available-for-sale as of December 31, 2015 and 2014 (in thousands):

Allowance for Doubtful Accounts, Billing Adjustments, and Contractual Allowances

Accounts receivable consist principally of trade receivables from customers and government or third-party healthcare insurance 
providers, and are generally unsecured and due within 30 days. Expected credit losses related to trade accounts receivable are 
recorded as an allowance for doubtful accounts within accounts receivable, net in the consolidated balance sheets. The provision 
for doubtful accounts is charged to general and administrative expenses.  When internal collection efforts on accounts have been 
exhausted, the accounts are written off by reducing the allowance for doubtful accounts.

Within Diagnostic Services, we record adjustments and credit memos that represent billing adjustments subsequent to the 

performance of service. A provision for billing adjustments is charged against Diagnostic Services revenues.

Our cardiac event monitoring services are provided primarily through an independent diagnostic testing facility model which 
allows us to bill Medicare, Medicaid, or one of the third-party healthcare insurers directly for services provided. Accounts receivable 
related to cardiac event monitoring are recorded at the time revenue is recognized, net of contractual allowances. Contractual 
allowances are estimated based on historical collections by Current Procedural Terminology (CPT) code for specific payors, or 
class of payors. A provision for contractual allowances is charged against Diagnostic Services revenues.

The following table summarizes our allowance for doubtful accounts, billing adjustments, and contractual allowances as of 

and for the years ended December 31, 2015, 2014, and 2013 (in thousands):

Inventory

43

Our inventories are stated at the lower of cost (first-in, first-out) or market (net realizable value) and we review inventory 
balances for excess and obsolete inventory levels on a quarterly basis. Costs include material, labor, and manufacturing overhead 
costs. We rely on historical information to support our excess and obsolete reserves and utilize our business judgment with respect 
to estimated future demand. Per our policy, we generally reserve 100% of the cost of inventory quantities in excess of a defined 
period of demand. Once inventory is reserved, we do not adjust the reserve balance until the inventory is sold or disposed.

The following table summarizes our reserves for excess and obsolete inventory as of and for the years ended December 31,

Long-Lived Assets including Finite Lived Purchased Intangible Assets

Long-lived assets consist of property and equipment and finite lived intangible assets. We record property and equipment at 
cost, and record other intangible assets based on their fair values at the date of acquisition. We calculate depreciation on property 
and equipment using the straight-line method over the estimated useful life of the assets which average 6 years for machinery and 
equipment, 3 years for computer hardware and software, and the lower of the lease term or an average of 5 years for leasehold 
improvements. Charges related to amortization of assets recorded under capital leases are included within depreciation expense. 
We calculate amortization on other intangible assets using either the accelerated or the straight-line method over the estimated 
useful life of the assets, based on when we expect to receive cash inflows generated by the intangible assets. Estimated useful 
lives for intangibles range from 5 to 9 years for customer relationships, 5 to 9 years for trademarks, 8 to 15 years for patents, and 
5 years for covenants not to compete.

Impairment losses on long-lived assets used in operations are recorded when indicators of impairment are present and the 
undiscounted cash flows estimated to be generated by those assets are less than the assets’ carrying amount. If such assets are 
considered to be impaired, the impairment to be recognized is measured by the amount by which the carrying amount of the assets 
exceeds the estimated fair value of the assets. No impairment losses were recorded on long-lived assets to be held and used during 
the years ended December 31, 2015, 2014, and 2013. During the year ended December 31, 2015, an impairment loss of $56,000 
was recorded related to the excess of the carrying amount above fair value of certain assets held for sale. No impairment losses 
were recorded on long-lived assets held for sale during the years ended December 31, 2014, or 2013.

Valuation of Goodwill

We  review  goodwill  for  impairment  on  an  annual  basis  during  the  fourth  quarter,  as  well  as  when  events  or  changes  in 
circumstances indicate that the carrying value may not be recoverable. We begin the process by assessing qualitative factors in 
determining whether it is more likely than not that the fair value of its reporting unit is less than its carrying amount. After performing 
the aforementioned assessment and upon review of the results of such assessment, we may begin performing step one of the two-
step impairment analysis by quantitatively comparing the fair value of the reporting unit to the carrying value of the reporting 
unit, including goodwill. If the carrying value of the long-term assets exceeds the fair value of the reporting unit, then we must 
perform the second step of the impairment test, whereby the carrying value of the reporting unit’s goodwill is compared to its 
implied fair value. If the carrying value of the goodwill exceeds the implied fair value, an impairment loss equal to the difference 
would be recorded. No goodwill impairment losses were recorded during the years ended December 31, 2015, 2014, and 2013.

Restricted Cash

As of December 31, 2015, we held $0.2 million of money market funds that are restricted from withdrawal as they are held as 

collateral for a letter of credit related to the building lease for the Poway, CA facility.

Restructuring

Restructuring  costs  are  included  in  income  from  operations  within  the  consolidated  statements  of  comprehensive  income.  
Losses  on  property  and  equipment  are  recorded  consistent  with  our  accounting  policy  related  to  long-lived  assets.  One-time 
termination benefits are recorded at the time they are communicated to the affected employees. Losses on property lease obligations 
are recorded when the lease is abandoned or when the contract is terminated. 

In February 2013, we announced a plan to restructure our Diagnostic Imaging business. In addition, we announced a plan in 
January 2014 to exit our 47,000 square foot former headquarters facility in Poway, California. Both restructuring initiatives were 
complete as of December 31, 2014. See Note 11 to the audited consolidated financial statements for further information.

Shipping and Handling Fees and Costs

We record all shipping and handling billings to customers as revenue earned for the goods provided. Shipping and handling 
costs are included in cost of revenues and totaled $0.6 million, $0.5 million, and $0.2 million for the years ended December 31, 
2015, 2014, and 2013, respectively.

Share-Based Compensation

We account for share-based awards exchanged for employee services in accordance with the authoritative guidance for share-
based compensation. Under this guidance, share-based compensation expense is measured at the grant date, based on the estimated 
fair value of the award, and is recognized as expense, net of estimated forfeitures, over the requisite service period.

Warranty

We generally provide a 12 month warranty on our gamma cameras. We accrue the estimated cost of this warranty at the time 
revenue is recorded and charge warranty expense to Diagnostic Imaging cost of revenues. Warranty reserves are established based 
on historical experience with failure rates and repair costs and the number of systems covered by warranty. Warranty reserves are 
depleted as gamma cameras are repaired. The costs consist principally of materials, personnel, overhead, and transportation. We 
review warranty reserves quarterly and, if necessary, make adjustments.

The  activities  related  to  our  warranty  reserve  for  the  years  ended  December 31,  2015,  2014,  and  2013  are  as  follows  (in 

thousands):

Basic and Diluted Net Income Per Share

Basic earnings per share (EPS) is calculated by dividing net income by the weighted average number of common shares and 
vested restricted stock units outstanding. Diluted EPS is computed by dividing net income by the weighted average number of 
common  shares  and  vested  restricted  stock  units  outstanding  and  the  weighted  average  number  of  dilutive  common  stock 
equivalents,  including  stock  options  and  non-vested  restricted  stock  units  under  the  treasury  stock  method.  Common  stock 
equivalents are only included in the diluted earnings per share calculation when their effect is dilutive. Shares used to compute 
basic net income per share include 5,063, and 44,522 vested restricted stock units for the years ended December 31, 2014, and 
2013, respectively. There were no vested restricted stock units included in the shares used to compute basic net income per share 
for the year ended December 31, 2015. 

The following table sets forth the computation of basic and diluted net income per share for the periods indicated (in thousands,

Antidilutive common stock equivalents are excluded from the computation of diluted earnings per share. Stock options and 
restricted stock units are antidilutive when the assumed proceeds per share are greater than the average market price of the common 
shares. In addition, in periods where net losses are incurred, stock options and restricted stock units with assumed proceeds per 
share less than the average market price of the common shares become antidilutive as well. 

The number of common share equivalents that were antidilutive were 984, 66,917, and 177,891 for the years ended December 

31, 2015, 2014, and 2013, respectively. 

Other Comprehensive Loss

Other comprehensive loss is defined as the change in equity during a period from transactions and other events and circumstances 

from non-owner sources. Comprehensive loss includes unrealized losses on our marketable securities. 

Income Taxes 

We provide for income taxes under the liability method. This approach requires the recognition of deferred tax assets and 
liabilities for the expected future tax consequences of differences between the tax basis of assets or liabilities and their carrying 
amounts in the financial statements. We provide a valuation allowance for deferred tax assets if it is more likely than not that these 
items will expire before we are able to realize their benefit. We calculate the valuation allowance in accordance with the authoritative 
guidance relating to income taxes, which requires an assessment of both positive and negative evidence regarding the realizability 
of these deferred tax assets when measuring the need for a valuation allowance. Significant judgment is required in determining 
any valuation allowance against deferred tax assets. As of December 31, 2014, due to a history of operating losses and other key 
operating factors, we concluded that a full valuation allowance was necessary to offset all of our deferred tax assets. A significant 
piece of objective negative evidence evaluated as of December 31, 2014, was the cumulative pretax loss incurred over the three-
year period ended December 31, 2014. During the year ended December 31, 2015, we concluded that it was more likely than not 
that a portion of our deferred tax assets would be realized through future taxable income. This conclusion was based on our 
restructuring efforts in 2013 and 2014 and resulting sustained profitability for the second half of 2013, 2014, and 2015, as well as 
our projections of positive future earnings and other key operating factors. As of September 30, 2015, we had generated cumulative 
pretax income over the preceding twelve quarter period, and therefore the objective negative evidence of a history of operating 
losses was no longer present.

The authoritative guidance for income taxes defines a recognition threshold and measurement attributes for financial statement 
recognition and measurement of a tax provision taken or expected to be taken in a tax return. The guidance also provides direction 
on  de-recognition,  classification,  interest  and  penalties,  accounting  in  interim  periods,  disclosure,  and  transition.  Under  the 
guidance, the impact of an uncertain income tax position on the income tax return must be recognized at the largest amount that 
is more-likely-than-not to be sustained upon audit by the relevant taxing authority. An uncertain income tax position will not be 
recognized if it has less than a 50% likelihood of being sustained. We recognize interest and penalties related to uncertain tax 
positions as a component of the income tax provision. 

Acquisitions 

On March 5, 2015, we acquired MD Office Solutions. On March 13, 2014, we acquired 100% of the membership interest of 
Telerhythmics, LLC. Both acquisitions were accounted for as business combinations. We measure all assets acquired and liabilities 
assumed, including contingent considerations, at fair value as of the acquisition date. Contingent purchase considerations to be 
settled in cash are remeasured to estimated fair value at each reporting period with the change in fair value recorded in general 

46

 
 
and administrative expense, a component of operating expenses. See Note 3 to the audited consolidated financial statements for 
further information.

Accounting Standards Updates

In February 2016, the FASB amended the existing accounting standards for the accounting for leases. The amendments are 
based on the principle that assets and liabilities arising from leases should be recognized within the financial statements. The 
Company is required to adopt the amendments beginning in 2019. Early adoption is permitted. The amendments must be applied 
using a modified retrospective transition approach and the FASB decided not to permit a full retrospective transition approach. 
The Company is currently evaluating the impact these amendments will have on its consolidated financial statements.

In January 2016, the FASB amended the existing accounting standards for the accounting for financial instruments. The 
amendments require equity investments, with certain exceptions, to be measured at fair value with changes in fair value recognized 
in net income. The new standard is effective prospectively for fiscal years beginning after December 15, 2017. We are currently 
evaluating the impact, if any, of adopting this guidance on our financial statements.

In  November  2015,  the  FASB  issued  guidance  which  requires  classification  of  all  deferred  tax  assets  and  liabilities  as 
noncurrent. The new standard is effective for fiscal years beginning after December 15, 2016, including interim periods within 
those fiscal years, with early adoption permitted. We have early adopted the guidance on a prospective basis for the year ended 
December 31, 2015. Therefore, the classification of deferred tax assets and liabilities in periods prior to the year ended December 
31, 2015 have not been changed from their original presentation.

In September 2015, the FASB issued guidance which eliminates the requirement for an acquirer to retrospectively adjust 
provisional amounts recorded in a business combination to reflect new information about the facts and circumstances that existed 
as of the acquisition date and that, if known, would have affected measurement or recognition of amounts initially recognized. As 
an alternative, the amendment requires that an acquirer recognize adjustments to provisional amounts that are identified during 
the measurement period in the reporting period in which the adjustment amounts are determined. The amendments require that 
the acquirer record, in the financial statements of the period in which adjustments to provisional amounts are determined, the 
effect on earnings of changes in depreciation, amortization, or other income effects, if any, as a result of the change to the provisional 
amounts, calculated as if the accounting had been completed at the acquisition date. The new standard is effective prospectively 
for fiscal years beginning after December 15, 2015, including interim periods within those fiscal years. We are currently evaluating 
the impact, if any, of adopting this guidance on our financial statements.

In July 2015, the FASB issued guidance that amends the guidelines for the measurement of inventory from lower of cost or 
market to the lower of cost and net realizable value (NRV). NRV is defined as the estimated selling prices in the ordinary course 
of business less reasonably predictable costs of completion, disposal, and transportation. Under existing standards, inventory is 
measured at lower of cost or market, which requires the consideration of replacement cost, NRV, and NRV less an amount that 
approximates a normal profit margin. This ASU eliminates the requirement to determine and consider replacement cost or NRV 
less an approximately normal profit margin for inventory measurement. The new standard is effective prospectively for fiscal 
years beginning after December 15, 2016. We are currently evaluating the impact, if any, of adopting this guidance on our financial 
statements.

In May 2014, the FASB issued guidance that outlines a single comprehensive model for entities to use in accounting for 
revenue arising from contracts with customers which supersedes most current revenue recognition guidance, including industry-
specific guidance. The guidance provides that an entity recognize revenue when it transfers promised goods or services to customers 
in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. This 
guidance also requires additional disclosure about the nature, amount, timing, and uncertainty of revenue and cash flows arising 
from customer contracts, including significant judgments and changes in judgments, and assets recognized from costs incurred to 
obtain or fulfill a contract. The guidance allows for either full retrospective or modified retrospective adoption and is currently 
scheduled to become effective for us in the first quarter of 2018. We are currently evaluating the alternative transition methods 
and the potential effects of the adoption of this guidance on our financial statements.

NOTE 3. 

Acquisitions

MD Office Solutions (2015)

On March 5, 2015, we entered into an Agreement of Merger and Plan of Reorganization (the Merger Agreement) to acquire 
MD Office Solutions (MD Office). MD Office is a provider of in-office nuclear cardiology imaging in the northern and central 
California regions. The acquisition expands the geographical region in which we are able to provide our in-office nuclear cardiology 
imaging services. 

Total consideration related to the Merger Agreement paid to the sellers was 610,000 shares of common stock of Digirad 
Corporation, with a total value at closing of $2,684,000, as well as settlement of a $15,000 accounts receivable balance owed to 
the Company.  The Company issued new shares for the consideration.  In addition, there is an earn-out opportunity of up to $400,000 
in cash over approximately three years based on the MD Office business meeting certain earnings before interest, taxes, depreciation, 
47

and amortization (EBITDA) milestones. The sellers will receive fifty percent of the EBITDA generated by the MD Office business 
in excess of the EBITDA milestone amounts, which are $650,000 for each of the annual periods ending December 31, 2015, 2016, 
and 2017, with the target for 2015 being prorated based on the close date.  

At December 31, 2015, we have estimated the fair value of the contingent earn-out opportunity to be $153,000. The earn-out 
opportunity is estimated based on actual performance for the period from the acquisition date through December 31, 2015, as well 
as the expected performance of the business over the period from January 1, 2016, through December 31, 2017, utilizing an income 
approach. It is reasonably possible that our estimate of the earn-out potential could change in the near term. Any adjustment in 
the estimated earn-out opportunity until settled will be recorded as a gain or loss to current operations in the period the estimate 
changes.

The Merger Agreement was also subject to a post-closing purchase price adjustment based on the final working capital balance, 
as defined in the Merger Agreement, as well as a Registration Rights Agreement related to the common shares provided to the 
sellers as part of the consideration.

purposes.

Included within the results for MD Office for the year ended December 31, 2015 are approximately $195,000 of transaction 
costs related to the acquisition. These costs are classified as general and administrative expenses in the consolidated statements 
of comprehensive income.

Telerhythmics, LLC (2014)

On March 13, 2014, we acquired 100% of the membership interest of Telerhythmics, LLC (Telerhythmics), a provider of 24-
hour cardiac monitoring services. We paid to the sellers of the membership interest (the Sellers) aggregate up-front consideration 
of $3.4 million and assumed approximately $131,000 in debt. In addition, there is an aggregate earn-out opportunity of up to 
$501,000 from the period March 14, 2014 through December 31, 2016 based on the Telerhythmics business meeting certain 
earnings before interest, taxes, depreciation, and amortization (EBITDA) milestones. The Sellers will receive fifty percent (50%) 
of the EBITDA generated by the Telerhythmics business in excess of the EBITDA milestone amounts, which are as follows:

• 
• 
• 

$415,000 of EBITDA for the period from the closing date through December 31, 2014, 
$825,000 of EBITDA for the period from January 1, 2015 through December 31, 2015; and 
$825,000 of EBITDA for the period from January 1, 2016 through December 31, 2016. 

At December 31, 2015, we have estimated the fair value of the contingent earn-out opportunity to be $22,000. The earn-out 
opportunity is estimated based on expected performance of the business over the period from January 1, 2016 through December 
31, 2016, utilizing an income approach. No earn-out consideration was earned by the Sellers for the period from the closing date 
through December 31, 2015. It is reasonably possible that our estimate of the earn-out potential could change in the near term. 
Any adjustment in the estimated earn-out opportunity until settled will be recorded as a gain or loss to current operations in the 
period the estimate changes.

The long-term debt was paid in full on March 28, 2014.

The goodwill recognized as part of the transaction primarily represents synergies between Digirad and Telerhythmics that were 
not separately identified as part of the acquisition valuation process. Telerhythmics activities are considered their own operating 
segment, which is aggregated into our Diagnostic Services reportable segment. The resulting goodwill from the acquisition is 
expected to be deductible for federal and state tax reporting purposes.      

The below tables display estimated pro forma results had the business acquisition been completed as of January 1, 2013. In 
deriving the pro forma results, we utilized the historical operating results of Telerhythmics and adjusted for the impact of the 
purchase accounting and transaction costs as if the acquisition occurred on January 1, 2013.

We categorize our assets and liabilities measured at fair value into a three-level hierarchy in accordance with the authoritative 
guidance for fair value measurements.  Assets and liabilities presented at fair value in our consolidated balance sheets are generally 
categorized as follows:

Level 1: 

Quoted prices in active markets for identical assets or liabilities. 

Level 2: 

Level 3: 

Observable inputs other than Level 1 prices, such as quoted prices for similar assets or liabilities, quoted prices 
in markets that are not active, or other inputs that are observable or can be corroborated by observable market 
data for substantially the full term of the assets or liabilities. 

Unobservable inputs that are supported by little or no market activity and that are significant to the fair value 
of the assets or liabilities. Such assets and liabilities may have values determined using pricing models, discounted 
cash flow methodologies, or similar techniques, and include instruments for which the determination of fair 
value requires significant management judgment or estimation. 

As required by the authoritative guidance for fair value measurements, financial assets and liabilities are classified in their 
entirety based on the lowest level of input that is significant to the fair value measurement. Our assessment of the significance of 
a particular input to the fair value measurement requires judgment, which may affect the valuation of assets and liabilities and 
their placement within the fair value hierarchy levels. The following table sets forth by level within the fair value hierarchy our 
assets that were recorded at fair value as of December 31, 2015 and 2014 (in thousands):

Our investments in corporate debt securities are valued based on quoted market prices for identical securities. Some of the 
corporate debt securities we hold do not trade on a daily basis. For investments that do not trade on a daily basis, we utilize a 
variety of pricing sources to determine fair value and corroborate the fair value by observing market data prior and subsequent to 
the balance sheet date.

Equity securities consist of shares of Perma-Fix Medical, a publicly traded company listed on the NewConnect market of the 
Warsaw Stock Exchange. Fair value of the Perma-Fix Medical investment is based on the closing price observed on December 31, 
2015. Given that there are days in which there are no trades of Perma-Fix Medical's stock, we corroborate the fair value by observing 
market data prior and subsequent to the balance sheet date.  

The acquisition related contingent consideration is related to the acquisitions of Telerhythmics, on March 13, 2014, and MD 
Office Solutions, on March 5, 2015. We reassess the fair value of the contingent consideration on a quarterly basis using the income 
approach, which is a Level 3 measurement. The estimation of the fair value of the contingent consideration requires significant 
management judgment, including estimating future cash flows associated with the respective businesses and determining the 
associated discount rate. The maximum possible consideration to be paid related to Telerhythmics and MD Office Solutions is 
$501,000 and $400,000, respectively. No minimum amount of contingent consideration is guaranteed to be paid related to either 
Telerhythmics or MD Office Solutions. No earn-out consideration was earned related to Telerhythmics for the period from the 
closing date of March 13, 2014 through December 31, 2015. Contingent consideration of $76,000 was earned related to MD Office 
Solutions for the period from the closing date of March 5, 2015 through December 31, 2015.

Goodwill has been recorded related to the acquisitions of MD Office in 2015, Telerhythmics in 2014, and Ultrascan in 2007. 
The related goodwill has been recorded within two separate reporting units within our Diagnostic Services segment. During the 
year ended December 31, 2014, we recorded $1.2 million of goodwill as a result of acquisition of Telerhythmics. During the year 
ended December 31, 2015, we recorded $1.6 million of goodwill as a result of acquisition of MD Office, bringing total goodwill 
to its current carrying value of $2.9 million. We determined the implied fair value of the goodwill for MD Office, Telerhythmics 
and Ultrascan utilizing the discounted cash flow method under the income approach. Under the income approach, we derived the 
fair value based on the present value of estimated future cash flows, which were based on historical data and assumptions pertaining 
to the market. 

During the second quarter of 2015, based on the quantitative performance of the Telerhythmics business compared to plan, we 
performed the first step of the goodwill impairment test which involves comparing the fair value of the reporting unit with the 
associated carrying value, including goodwill. We determined the fair value of the reporting unit using the income valuation 
approach. The reporting unit’s fair value exceeded the associated carrying amount of the reporting unit; therefore the second step 
of the goodwill impairment test was not necessary.

Subsequently,  during  the  fourth  quarter  of  2015,  we  performed  our  annual  goodwill  impairment  testing. We performed  a 
qualitative assessment of all reporting units to estimate whether it is more likely than not that the fair value of each reporting 
unit was less than its carrying amount. In performing this qualitative assessment, we assessed relevant events and circumstances 
that may impact the fair value and the carrying amount of each reporting unit. Factors that were considered included, but were 
not limited to, the following: (1) macroeconomic conditions; (2) industry and market conditions; (3) overall financial performance 
and  expected  financial  performance;  (4) other  entity  specific  events.  Based  on  the  results  of  this  qualitative  assessment,  we 
determined that it is more likely than not that the reporting units were not impaired.

Changes in the carrying amount of goodwill from December 31, 2013 to December 31, 2015 by reportable segment are as

Commitments and Contingencies

Leases

We currently lease facilities and certain automotive equipment under non-cancelable operating leases expiring from January 
1, 2016 through November 30, 2021. Rent expense is recognized on a straight-line basis over the initial lease term and those 
renewal periods that are reasonably assured as determined at lease inception. The difference between rent expense and rent paid 

53

is recorded as deferred rent and is included in other current and long-term liabilities. Rent expense was approximately $1.3 million 
for the years ended December 31, 2015 and 2014 and $1.4 million for the year ended December 31, 2013.  

As of December 31, 2015, we financed certain information technology and medical equipment and vehicles under capital leases. 
These obligations are secured by the specific equipment financed under each lease and will be repaid monthly over the remaining 
lease terms through December 31, 2019. 

We are committed to making future cash payments on non-cancelable operating leases and capital leases (including interest). 
The future minimum lease payments due under both non-cancelable operating leases and capital leases having initial or remaining 
lease terms in excess of one year as of December 31, 2015 are as follows (in thousands):

Annual Meeting Litigation. In May 2013, we were served with a complaint in Delaware Chancery Court by one of our shareholders, 
the Red Oak Fund, L.P. (Red Oak). In summary, the complaint alleged that the Annual Meeting of Shareholders election process 
(the Election) was improperly conducted. Red Oak sought to have the results of the Election voided and to compel Digirad to 
conduct a new Annual Meeting process. On October 23, 2013, the Delaware Chancery Court issued a memorandum opinion in 
favor of the Company which upheld the Election as valid. 

Other matters. In the normal course of business, we have been, and will likely continue to be, subject to litigation or administrative 
proceedings incidental to our business, such as claims related to customer disputes, employment practices, wage and hour disputes, 
product liability, professional liability, commercial disputes, licensure restrictions or denials, and warranty or patent infringement. 
Responding to litigation or administrative proceedings, regardless of whether they have merit, can be expensive and disruptive to 
normal business operations. We are not able to predict the timing or outcome of these matters.

NOTE 8. 

 Share-Based Compensation

At December 31, 2015, we have two active equity incentive plans, the 2011 Inducement Stock Incentive Plan (the 2011 Plan) 
and the 2014 Equity Incentive Award Plan (the 2014 Plan), (collectively the Plans), under which stock options, restricted stock 
units, and other stock based awards may be granted to employees and non-employees, including members of our Board of Directors. 
Terms of any equity instruments granted under the Plans are approved by the Board of Directors. Stock options typically vest over 
the requisite service period of one to four years and have a contractual term of seven to ten years. Restricted stock units generally 
vest over one to four years. Under the Plans, we are authorized to issue an aggregate of 1,856,733 shares of common stock. As of 
December 31, 2015, the Plans had 968,733 shares available for future issuance. The number of shares reserved for issuance under 
the 2014 Plan is subject to increase by any shares under the 2004 Equity Incentive Award Plan (the 2004 Plan) that are forfeited, 
expire, or are canceled. As of December 31, 2015, the number of shares provided for issuance under the 2014 Plan due to forfeited, 
expired, and canceled shares under the 2004 Plan was 10,248 shares.

Stock Options

The estimated fair value of our stock options is determined using the Black-Scholes model. All stock options were granted with 
an exercise price equal to the fair value of the common stock on the grant date. The weighted-average grant date fair value of 
employee stock options granted during the years ended December 31,  2014 and 2013 was $0.70, and $1.06 per share, respectively, 
which was estimated using the following weighted-average assumptions. There were no employee stock options granted during 
the year ended December 31, 2015.

The determination of the fair value of stock options using an option valuation model is affected by our stock price, as well as 
assumptions regarding a number of complex and subjective variables. The volatility assumption is based on the historical volatility 
of our common stock over a period of time equal to the expected term of the stock options. The expected term of our stock options 
is based on historical experience. The risk-free rate for the expected term of the option is based on the U.S. Treasury yield in effect 
at the time of grant. The expected dividend yield is based on the current annualized dividend rate per share divided by the historical 
average stock price. At the time of the grants, for the year ended December 31, 2013, we had no plans to pay a dividend and no 
history of paying a dividend previously and as such an expected dividend yield of zero was utilized for purposes of determining 
fair value of the associated stock options. 

A summary of our stock option award activity as of and for the year ended December 31, 2015 is as follows (in thousands,

As share-based compensation expense under the authoritative guidance for share-based payments is based on awards ultimately 
expected to vest, it is reduced for estimated forfeitures. The guidance requires forfeitures to be estimated at the time of grant and 
revised, if necessary, in subsequent periods if actual forfeitures differ from those estimates.

At December 31, 2015, total unrecognized compensation cost related to unvested stock options was $0.2 million, which is 

expected to be recognized over a weighted-average period of 1.2 years.

Upon exercise, we issue new shares of common stock. Cash received from stock option exercises was $0.6 million during the 
year ended December 31, 2015, $0.2 million during the year ended December 31, 2014, and $0.9 million for the year ended 
December 31, 2013. The total intrinsic value of stock options exercised was $0.2 million during the year ended December 31, 
2015,  $0.1 million during the year ended December 31, 2014, and  $0.9 million during the year ended 2013.

Restricted Stock Units

Under guidance for share-based payments, the fair value of our restricted stock awards is based on the grant date fair value of 
our common stock. All restricted stock units were granted with no purchase price. Vesting of the restricted stock awards is subject 
to service conditions, as well as the attainment of additional performance objectives for certain of the awards. The weighted-
average grant date fair value of the restricted stock units was $4.14 and $3.81 per share during the years ended December 31, 2015 
and 2014, respectively. There were no restricted stock units granted during the year ended December 31, 2013.

As of December 31, 2015, we had federal and state income tax net operating loss carryforwards of $90.3 million and $25.0 
million, respectively. Federal loss carryforwards will begin to expire in 2018 unless previously utilized. State loss carryforwards 
of approximately $3.6 million expired in 2015, and approximately $0.9 million is set to expire in 2016 unless previously utilized. 
We also have federal and California research and other credit carryforwards of approximately $1.8 million and $2.1 million, as 
of December 31, 2015 and 2014, respectively. The federal credits will begin to expire in 2018. The California research credits 
have no expiration. Pursuant to Internal Revenue Code Sections 382 and 383, use of our net operating loss and credit carryforwards 
may be limited because of a cumulative change in ownership greater than 50% which may have occurred or which may occur in 
the future. A valuation allowance has been recognized to offset the deferred tax assets, as realization of such assets has not met 
the "more likely than not" threshold required under the authoritative guidance of accounting for income taxes.

We recognize windfall tax benefits associated with the exercise of share-based compensation directly to stockholders' equity 
only when realized. Accordingly, deferred tax assets are not recognized for the net operating loss carryforwards resulting from 
windfall tax benefits. At December 31, 2015, deferred tax assets do not include approximately $0.3 million of excess tax benefits 
from share-based compensation.

Included  in  the  unrecognized  tax  benefits  of    $3.9  million  at  December 31,  2015  was  $3.2  million  of  tax  benefits  that,  if 
recognized, would reduce our annual effective tax rate, subject to the valuation allowance. We do not expect our unrecognized 
tax benefits to change significantly over the next 12 months.

We file income tax returns in the U.S. and in various state jurisdictions with varying statutes of limitations. We are no longer 
subject to income tax examination by tax authorities for years prior to 2011; however, our net operating loss carryforwards and 
research credit carryforwards arising prior to that year are subject to adjustment. Our policy is to recognize interest expense and 
penalties related to income tax matters as a component of income tax expense. There were no accrued interest and penalties as of 
December 31, 2015 and 2014, and no interest and penalties were recognized during the years ended December 31, 2015, 2014, 
and 2013.

NOTE  10. 

Employee Retirement Plan

We have 401(k) and Simple IRA retirement plans under which employees may contribute up to 100% of their annual salary, 
within IRS limits. The Company contributions to the retirement plans totaled $0.2 million for each of the years ended December 31, 
2015, 2014, and 2013.

NOTE  11.  

Restructuring Charges 

Diagnostic Imaging restructuring initiative

On February 28, 2013, we announced a plan to restructure our Diagnostic Imaging business to significantly reduce costs, 
including a reduction in force (the Diagnostic Imaging restructuring initiative). The Diagnostic Imaging restructuring initiative 
was completed as of June 30, 2014. A total of $1.8 million of costs were incurred related to the Diagnostic Imaging restructuring 
initiative, with $29 thousand incurred during the year ended December 31, 2014, and $1.7 million incurred in the year ended 
December 31, 2013.

Facilities restructuring initiative

On January 27, 2014, we announced a plan to exit our 47,000 square foot former headquarters facility in Poway, California  
(the Facilities restructuring initiative). This action was undertaken as the facility had excess space and capacity given our current 
operating plan. We entered into a termination agreement to end the lease on the facility as of April 30, 2014. The original term of 
the lease would have continued through February 29, 2016. Concurrently with the termination of the lease for the 47,000 square 
foot Poway, California facility, we entered into a new lease agreement on January 23, 2014 for a separate 21,300 square foot 
facility in Poway, California to house our Diagnostic Imaging operations. 

As a result of the Facilities restructuring initiative, we incurred a total of $0.7 million in restructuring charges, all of which 
were incurred during the year ended December 31, 2014. The charges were comprised of lease termination, moving and other 
related costs. All Facilities restructuring charges were included in the Diagnostic Imaging segment. Restructuring liabilities and 
associated charges were measured at fair value as incurred.

NOTE  12. 

Perma-Fix Medical Stock Subscription and Supply Agreements

On  July  27,  2015,  we  entered  into  a  Stock  Subscription Agreement  (the  Subscription Agreement)  and  Tc-99m  Supplier 
Agreement (the Supply Agreement) with Perma-Fix Medical, S.A. (Perma-Fix Medical), a publicly traded company listed on the 
NewConnect market of the Warsaw Stock Exchange. Perma-Fix Medical is a subsidiary of Perma-Fix Environmental Services, 
Inc. (NASDAQ: PESI). Perma-Fix Medical is developing a proprietary process to produce Technetium-99m (Tc-99m) resin from 
non-enriched uranium sources for purposes of creating nuclear imaging isotopes. Under the terms of the Subscription Agreement, 
we invested $1 million USD in exchange for 71,429 shares of Perma-Fix Medical, which constituted approximately 5.4% of the 
outstanding common shares of Perma-Fix Medical at the time of investment. Under Polish law, issuance of the shares required 

58

 
 
approval of the shares by a Polish court which occurred on October 12, 2015. The investment in Perma-Fix Medical is accounted 
for  as  an  available-for-sale  security.  In  connection  with  the  Subscription Agreement,  the  Company's  President  and  CEO  was 
appointed to the Supervisory Board of Perma-Fix Medical. See Note 13 to the audited consolidated financial statements for further 
information regarding Perma-Fix Medical and Perma-Fix Environmental Services, Inc. 

Pursuant to the Supply Agreement, should Perma-Fix Medical successfully complete development of the new Tc-99m resin, 
Perma-Fix Medical will supply us or our preferred nuclear pharmacy supplier with Tc-99m at a preferred rate and we will purchase 
agreed upon quantities of such Tc-99m for our nuclear imaging operations, either directly or in conjunction with our preferred 
nuclear pharmacy supplier.

Of the $1 million investment in Perma-Fix Medical, $45,000 of value was allocated to the supply agreement with the remaining 
value allocated to the 71,429 Perma-Fix Medical shares. We immediately expensed the  $45,000 of value associated with the 
supply agreement. In addition, we realized a loss of $233,000 related to the 71,429 Perma-Fix Medical shares due to the initial 
excess of the transaction price over fair value. 

NOTE  13. 

Related Party Transaction

Mr. John Climaco currently serves as a Director of the Company and a member of the Compensation, Corporate Governance 
and Strategic Advisory committees of the Board. Mr. Climaco also serves as a Director of Perma-Fix Environmental Services, 
Inc. (NASDAQ: PESI). Further, on June 2, 2015, Mr. Climaco was elected as the Executive Vice President of Perma-Fix Medical 
S.A.,  a  majority-owned  Polish  subsidiary  of  Perma-Fix  Environmental  Services,  Inc. As  described  in  Note  12  to  the  audited 
consolidated financial statements, on July 27, 2015, we entered into a Stock Subscription Agreement (the Subscription Agreement) 
and Tc-99m Supplier Agreement (the Supply Agreement) with Perma-Fix Medical. Under the terms of the Subscription Agreement, 
we invested $1 million USD in exchange for 71,429 shares of Perma-Fix Medical. Pursuant to the Supply Agreement, should 
Perma-Fix Medical successfully complete development of the new Tc-99m resin, Perma-Fix Medical will supply us or our preferred 
nuclear pharmacy supplier with Tc-99m at a preferred rate and we will purchase agreed upon quantities of such Tc-99m for our 
nuclear imaging operations, either directly or in conjunction with our preferred nuclear pharmacy supplier. In addition, in connection 
with the Subscription Agreement, the Company's President and CEO was appointed to the Supervisory Board of Perma-Fix Medical.

NOTE 14. 

Surgical Imaging Asset Sale and License Agreement

On July 31, 2013, we entered into an asset purchase agreement with Novadaq Technologies Inc. (Novadaq). Under the terms 
of the asset purchase agreement, we sold Novadaq all of our assets specifically related to an uncommercialized surgical imaging 
system previously in development. We also licensed certain existing Company technology to Novadaq for their use in the peri-
operative field. In exchange, we received upfront consideration of $2.0 million, and could receive up to $1.0 million in deferred 
contingent payments based on the achievement of specific regulatory and commercial milestones. In addition a royalty on sales, 
if any, will be paid for a period of five years from the date of the first commercial sale of the related surgical imaging system. 

We identified the deliverables at the inception of the agreements and determined that the tangible assets, consisting of inventory 
parts, and intangible assets, consisting of the technology license and various patents and know-how, individually represent separate 
units of accounting because each deliverable has standalone value. The best estimated selling prices for these units of accounting 
were determined using the income method for the intangible assets, and cost plus a reasonable margin basis for the tangible assets. 
The arrangement consideration was allocated to the deliverables based on the relative selling price method. 

The amount of allocable arrangement consideration is limited to the amount that is not contingent upon meeting other specified 
performance conditions (the non-contingent amount); therefore, the amount allocated to the deliverables was limited to the upfront 
cash received of $2.0 million. A gain of $1.6 million representing the $2.0 million of upfront consideration less legal, consulting, 
and other transaction fees, as well as the cost basis of the inventory was recorded during the year ended December 31, 2013. 

We will recognize contingent consideration if and when earned.

NOTE 15. 

Segments

Our reporting segments have been determined based on the nature of the products and/or services offered to customers or the 
nature of their function in the organization. We evaluate performance based on the operating income (loss) contributed by each 
segment. Our operating segments include Diagnostic Imaging, Digirad Imaging Solutions, and cardiac event monitoring from our 
Telerhythmics  acquisition  on  March  13,  2014  (See  Note  3).  For  financial  reporting  purposes,  we  aggregate  Digirad  Imaging 
Solutions and cardiac event monitoring due to their similar economic and operational characteristics. Summarized annual data for

NOTE 17. 

Subsequent Events

Credit Facility

On January 1, 2016, Digirad and certain of its subsidiaries entered into a Credit Agreement (the “Credit Agreement”) with 
Wells Fargo Bank, National Association (“Wells Fargo”) as administrative agent (“Agent”) and as sole lead arranger and sole book 
runner.

The Credit Agreement is a five-year credit facility (maturing in January 2021) with a maximum credit amount of $40,000,000 
(the “Credit Facility”). The Credit Facility consists of a term loan of $20,000,000 (“Term Loan A”), a second term loan of $7,500,000 
(“Term Loan B”), and a revolving credit facility with a maximum commitment of $12,500,000 (the “Revolver”). 

At the Borrower’s option, the Credit Facility will bear interest at either (i) the LIBOR Rate, as defined in the Credit Agreement, 
plus 2.5% for Term Loan A, 5.0% for Term Loan B, and 2.0% for the Revolver; or (ii) the Base Rate, as defined below, plus 1.5% 
for Term Loan A, 4.0% for Term Loan B, and 1.0% for the Revolver. As further defined in the Credit Agreement, “Base Rate” 
means the greatest of (a) the Federal Funds Rate (as defined in the Credit Agreement) plus 0.5%, (b) the LIBOR Rate (which rate 
will be calculated based upon an interest period of one month and will be determined on a daily basis), plus 1%, and (c) the rate 
of interest announced, from time to time, within Wells Fargo at its principal office in San Francisco as its “prime rate.”

On January 4, 2016, the Company used the financing made available under the Credit Facility to fund a portion of the purchase 
price related to the Company’s acquisition of Project Rendezvous Holding Corporation (“PRHC”) described below. The draw on 
the Credit Facility on January 4, 2016 was as follows: $20,000,000 on Term Loan A, $7,500,000 on Term Loan B and $6,117,220 
on the Revolver.

The Credit Agreement contains certain representations, warranties, events of default, mandatory prepayment requirements, as 
well  as  certain  affirmative  and  negative  covenants  customary  for  Credit Agreements  of  this  type.  These  covenants  include 
restrictions on borrowings, investments, and divestitures, as well as limitations on the Company’s ability to make certain restricted 
61

payments, including payment of dividends. These restrictions do not prevent or prohibit the payment of dividends by the Company 
consistent with past practice, subject to satisfaction of certain conditions. Upon the occurrence and during the continuation of an 
event of default under the Credit Agreement, the Lenders may, among other things, declare the loans and all other obligations 
under the Credit Agreement immediately due and payable and increase the interest rate at which loans and obligations under the 
Credit Agreement bear interest. Pursuant to a separate Guaranty and Security Agreement dated January 1, 2016, between the 
Company, its subsidiaries and Wells Fargo, the Credit Facility is secured by a first-priority security interest on substantially all of 
the assets of the Company and its subsidiaries and a pledge of all shares and membership interests of the Company’s subsidiaries.

Acquisition of Project Rendezvous Holding Corporation / DMS Health 

On January 1, 2016 (the “Closing Date”), pursuant to the Stock Purchase Agreement, dated as of October 13, 2015, and as 
amended  on  December  31,  2015  (the  “Purchase  Agreement”),  by  and  among  Digirad,  PRHC,  the  stockholders  of  PRHC 
(collectively, “Stockholders”), and Platinum Equity Advisors, LLC as the Stockholder representative, we completed the acquisition 
from  the  Stockholders,  for  $36,000,000  in  cash  (subject  to  certain  adjustments)  (the  “Purchase  Price”),  of  all  the  issued  and 
outstanding common stock of PRHC (the “DMS Transaction”). On January 4, 2016, the Company funded payment of the Purchase 
Price with a combination of cash-on-hand and the financing made available under the Credit Facility.

On the Closing Date, PRHC became a wholly owned subsidiary of the Company. PRHC is the ultimate parent of DMS Health 
Technologies, Inc., a provider of mobile healthcare solutions and related sales and services to small and regional hospitals throughout 
the United States, with a large concentration in the upper Midwest region.

We expect to account for the transaction as a business combination and are in the process of determining the allocation of the 
purchase price to acquired assets and assumed liabilities, as well as preparing pro forma financial information. A determination 
of the acquisition-date fair values of the assets acquired and the liabilities assumed is pending the completion of an independent 
appraisal and other evaluations and therefore further disclosures have not been made. 

Dividend

On February 1, 2016, the Company announced a dividend of $0.05 payable to shareholders of record as of February 16, 2016. 

The dividend was paid on February 29, 2016.

CHANGES  IN  AND  DISAGREEMENTS  WITH  ACCOUNTANTS  ON  ACCOUNTING  AND 
FINANCIAL DISCLOSURES

ITEM 9A. 

CONTROLS AND PROCEDURES

(1) Evaluation of Disclosure Controls and Procedures

We maintain disclosure controls and procedures that are designed to ensure that information required to be disclosed in our 
Securities and Exchange Commissions Act of 1934 reports is recorded, processed, summarized, and reported within the time 
periods specified in the Securities and Exchange Commission’s rules and forms and that such information is accumulated and 
communicated to our management, including our chief executive officer and chief financial officer, as appropriate, to allow for 
timely decisions regarding required disclosure. In designing and evaluating the disclosure controls and procedures, we recognize 
that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving 
the desired control objectives, and management is required to apply its judgment in evaluating the cost-benefit relationship of 
possible controls and procedures.

We carried out an evaluation, under the supervision and with the participation of our management, including our chief executive 
officer and chief financial officer, of the effectiveness of the design and operation of our disclosure controls and procedures, as 
defined in Rules 13a-15(e) and 15d-15(e) of the Exchange Act. Based on that evaluation, our chief executive officer and chief 
financial officer concluded that our disclosure controls and procedures were effective as of December 31, 2015.

Our disclosure controls and procedures are designed to provide reasonable assurance of achieving their objectives as specified 
above. Management does not expect, however, that our disclosure controls and procedures will prevent or detect all errors and 
fraud. Any internal control system, no matter how well designed and operated, can provide only reasonable, not absolute, assurance 
that its objectives will be met. Further, no evaluation of controls can provide absolute assurance that misstatements due to error 
or fraud will not occur or that all control issues and instances of fraud, if any, within the Company have been detected.

(2) Management’s Report on Internal Control over Financial Reporting

Our management is responsible for establishing and maintaining adequate internal control over financial reporting, as such 
term is defined in Rules 13a-15(f) and 15d-15(f) of the Exchange Act. Under the supervision and with the participation of our 
management, including our chief executive officer and chief financial officer, we conducted an evaluation of the effectiveness of 
our internal control over financial reporting based on the framework in Internal Control—Integrated Framework (2013) issued 
by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). Because of its inherent limitations, internal 
control over financial reporting may not prevent or detect all misstatements. Also, projections of any evaluation of effectiveness 
to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree 
of compliance with the policies or procedures may deteriorate. Therefore, even those systems determined to be effective can 
provide only reasonable assurance with respect to financial statement preparation and presentation. Based on our evaluation under 
the framework in Internal Control—Integrated Framework (2013), our management concluded that our internal control over 
financial reporting was effective as of December 31, 2015.

The effectiveness of our internal control over financial reporting as of December 31, 2015 has been audited by BDO USA, 

LLP, an independent registered public accounting firm, as stated in its report, which we include herein.

(3) Changes in Internal Control over Financial Reporting

There were no changes in our internal control over financial reporting during our fourth quarter ended December 31, 2015 that 

have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

Board of Directors and Stockholders
Digirad Corporation

We have audited Digirad Corporation’s internal control over financial reporting as of December 31, 2015, based on criteria 
established in Internal Control — Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the 
Treadway Commission (the COSO criteria). Digirad Corporation’s management is responsible for maintaining effective internal 
control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in 
the accompanying Item 9A, Management’s Report on Internal Control Over Financial Reporting. Our responsibility is to express 
an opinion on the company’s internal control over financial reporting based on our audit. 

We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States). 
Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control 
over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control 
over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating 
effectiveness of internal control based on the assessed risk. Our audit also included performing such other procedures as we 
considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion. 

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the 
reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally 
accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that 
(1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions 
of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation 
of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the 
company are being made only in accordance with authorizations of management and directors of the company; and (3) provide 
reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s 
assets that could have a material effect on the financial statements. 

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, 
projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because 
of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate. 

In our opinion, Digirad Corporation maintained, in all material respects, effective internal control over financial reporting as 

of December 31, 2015, based on the COSO criteria. 

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), 
the  consolidated  balance  sheet  of  Digirad  Corporation  as  of  December 31,  2015,  and  the  related  consolidated  statements  of 
comprehensive income, stockholders’ equity, and cash flows for the year then ended and our report dated March 1, 2016 expressed 
an unqualified opinion thereon.
