2020 ANNUAL REPORT

Message from the CEO
To our Shareholders, 

2020  was  a  year  of  transformative  positioning  and  progress.  We 
worked hard to overcome the challenges of the global pandemic and 
the unexpected decline in demand from our former largest customer. 
Yet,  during  this  extraordinarily  challenging  year,  we  also  acquired 
Holzworth, controlled our costs, increased our gross profit margins, 
and  ended  the  year  with  strong  bookings  growth.  Our  success 
responding to and managing through these challenges is attributable 
to the resilience and strength of our employees, our culture, and the 
significant value of our global brands.

We  have  continued  to  execute  on  our  mission  to  bring  specialized 
solutions  that  enable  the  development,  test,  and  deployment 
of  wireless  communication  and  connectivity.  We  launched  new 
products  to  market,  and  we  executed  on  our  acquisition  strategy. 
We  believe  we  are  now  at  an  inflection  point  for  the  business,  and 
the accomplishments during the year have expanded our addressable 
markets,  grown  our  customer  base,  increased  our  backlog,  and 
positioned us for growth in the year ahead and beyond.

We  remain  confident  in  our  strategy,  our  people  and  our  future 
focused on growth opportunities in 5G, spectrum deployment, private 
networks, and satellite and military applications.

Leading through Change and Challenges  
Operational agility tackles the challenges of the pandemic and safeguards 
our employees; a realigned structure balances reduced demand from our 
former largest customer and positions us well for future growth

We adjusted our cost structure and operating plan entering 2020 to 
address  an  unexpected  decline  in  demand  from  our  former  largest 
customer. Despite this obstacle, we maintained our investments and 
conviction  in  our  R&D  programs  and  our  higher  margin,  growth 
businesses.

In  the  first  quarter  of  2020  we  also  made  significant  modifications 
to  our  operations  in  response  to  the  unexpected  impacts  of  the 
global  pandemic. As  a  result,  our  goals  throughout  the  year  focused 
on  protecting  the  health  and  safety  of  our  employees,  serving  our 
customers’  needs  with  unparalleled  service  and  commitment,  and 
continued investments in the future of our business.

We  are  pleased  we  accomplished  each  of  these  goals  in  2020.  Our 
culture has been strengthened by new skills and experiences and we 
have realized operational improvements during this challenging period 
of  time. We  have  also  fueled  innovation,  realized  greater  efficiencies 
and have an increased excitement and potential about our future.

Growth orientation and execution
Holzworth  acquisition  and  integration  success,  continued  new  product 
launches, and added CRO leadership

In  February  2020  we  closed  the  acquisition  of  Holzworth 
Instrumentation,  a  specialized  provider  of  noise  measurement  and 
synthesis  for  precise  testing  requirements.  Holzworth’s  products 
serve growing market trends including 5G, advanced semiconductor 
test  requirements,  satellite  communication,  military,  aerospace  and 
quantum computing. 

The  acquisition  leverages  our  existing  Test  &  Measurement  sales 
channels,  customer  relationships  and  operational  platform.  We 
successfully integrated the business  and Holzworth’s results for 2020 
exceeded our expectations. We are excited about Holzworth’s future 
opportunities.

In  addition  to  our  successful  M&A  execution,  our  strategy  includes 
organic  growth  driven  by  R&D  investments  and  new  product 
introductions.  In  the  last  four  years,  we  released  22  new  products, 
nine  of  which  were  launched  in  2020  alone.  These  investments 
continue  to  advance  our  leadership  in  network  densification  and 
spectrum  deployment,  advance  our  LTE  and  5G  software  offerings, 
and  innovate  sophisticated  test  and  measurement  solutions  for 
applications in defense, radar and satellite communications, quantum 
computing,  and  applications  for  the  semiconductor  and  aerospace 
industries as well as the military, and large defense contractors. Like 
all  long-term  investments,  our  R&D  and  new  product  launches  are 
expected to drive success over many years.

Our  focus  on  driving  growth  also  includes  our  investments  in  our 
executive  team  where  we  added  a  Chief  Revenue  Officer,  Alfred 
Rodriguez,  from  Xilinx.  He  is  an  experienced  and  skilled  sales 
executive  with  the  vision  and  leadership  to  help  us  realize  the 
potential  of  our  new  products  and  software  solutions  in  markets 
poised for growth.

Execution and Delivery
Profitability, Cash Flow, Bookings and Backlog Growth

During  2020,  we  increased  our  consolidated  gross  profit  margin  to 
50.2%, compared to 48.4% in 2019 and above our long-term target of 
50%. We also significantly increased our cash flow from operations to 
approximately $3 million, and we generated four strong quarters of 
bookings, which contributed to our backlog increasing 117% from the 
prior year to $8.3 million at year-end.

Our increase in gross margins was driven by the successful execution 
of  our  strategy  to  drive  increased  growth  of  our  higher  margin 
business  in Test  &  Measurement  solutions,  including  Holzworth,  and 
the increase of software and services revenues in our Radio, Baseband, 
and Software solutions.

Our  bookings  also  include  significant  qualitative  wins. This  includes 
the return of demand for our RBS hardware cards as well as six new 
customers for our software and services solutions, demonstrating the 
momentum  in  our  NXP  collaboration  and  advancement  of  our  4G 
and 5G software. Importantly, we exited the year with our strongest 
quarter  of bookings, helping increase our backlog and visibility into 
the year ahead.

Looking ahead, the expected increased spending by carriers deploying 
spectrum,  growth  in  private  network  buildouts,  and  the  expansion 
of  satellite  communications  along  with  other  secular  growth  trends 
driven by 5G are expected to drive meaningful opportunities for our 
business.  Our  long-term  customer  relationships,  agile  approach,  and 
commitment to innovation and quality are aligned to revenue growth 
and customer success.

We  are  dedicated  to  creating  unmatched  value  for  our  customers 
enabling  the  development,  testing,  and  deployment  of  wireless 
technology and communications.

Thank you for your continued support of Wireless Telecom Group.

Timothy Whelan, 

Chief Executive Officer

Item 1.  Business 

Overview 

PART I 

Wireless Telecom Group, Inc., a New Jersey  corporation, together with its subsidiaries (“we”, “us”, “our”  or the “Company”), 
specializes in the design and manufacture of advanced radio frequency and microwave devices which enable the development, testing 
and  deployment  of  wireless  technology.  The  Company  provides  unique,  highly  customized  and  configured  solutions  which  drive 
innovation across a wide range of traditional and emerging wireless technologies.   

Wireless  Telecom  Group  is  comprised  of  five  brands  –  Microlab,  Boonton,  Noisecom,  CommAgility  and  Holzworth.        The 
Company is organized as one reporting segment as of result of certain internal reorganizations occurring in the six to nine months prior 
to June 2020.   Prior to June 2020, the Company was organized in three reporting segments.  In June 2020 we determined that the Chief 
Operating  Decision  Maker (“CODM”)  as  defined  in  Accounting  Standards  Codification  (“ASC”)  280  Segment  Reporting  evaluates 
operating  results  and  makes  decisions  on  how  to  allocate  resources  at  the  consolidated  level.    Although  the  CODM  reviews  key 
performance indicators including bookings, shipments and gross profit at a product group level, this information by itself is not sufficient 
enough to make operating decisions.  Rather, operating decisions are made based on review of consolidated profitability metrics rather 
than the individual results of each product group.  The Company continues to report gross profit at the product group level.  Our product 
groups  are  organized  as  follows:    Radio  Frequency  Components  (“RFC”)  is  comprised  of  our  Microlab  brand;  Radio,  Baseband, 
Software  (“RBS”)  is  comprised  of  our  CommAgility  brand;  and  Test  and  Measurement  (“T&M”)  is  comprised  of  our  Boonton, 
Noisecom and Holzworth brands.         

Our  customers  include  wireless  carriers,  aerospace  and  defense  companies,  military  and  government  agencies,  satellite 
communication companies, network equipment manufacturers, tower companies, semiconductor companies, system integrators, neutral 
host providers, medical device manufacturers and other global technology companies.   

Our products include components, modules, instruments, systems and software used across the lifecycle of wireless connectivity 
and  communication  development,  deployment  and  testing.    Our  services  include  software  customization,  calibration,  repair  and 
maintenance.  Our customers use these products in the development and deployment of long-term evolution (“LTE”) and 5G private 
networks, small cell solution development and deployment, 5G test environments, automated test environments, research labs, network 
densification and deployment, expansion and upgrade of distributed antenna systems, and medical device manufacturing   In addition, 
the Company’s products are used  in the development and testing  of  satellite communication systems, radar systems, semiconductor 
manufacturing, automotive electronics and avionics.  

The consolidated financial statements for the 2020 fiscal year include the accounts of Wireless Telecom Group, Inc., doing business 
as, and operating under the trade name Noise Com, Inc., and its wholly owned subsidiaries including Boonton Electronics Corporation, 
Microlab/FXR, Wireless Telecommunications Ltd., CommAgility Limited and Holzworth Instrumentation, Inc. The corporate website 
address is www.wirelesstelecomgroup.com. Noise Com, Inc., Boonton Electronics Corporation, Microlab/FXR, CommAgility Limited 
Ltd.,  and  Holzworth  Instrumentation,  Inc.  are  hereinafter  referred  to  as  “Noisecom”,  “Boonton”,  “Microlab”,  “CommAgility”  and 
“Holzworth”, respectively. 

Market 

Since the Company’s incorporation in the State of New Jersey in 1985, it has been primarily engaged in supplying noise source 
components  and  instruments,  electronic  testing  and  measurement  instruments,  and  radio  frequency  (“RF”)  passive  components  to 
customers.    With  the  CommAgility  acquisition  in  February  2017,  the  Company  expanded  to  include  the  delivery  of  digital  signal 
processing hardware cards and the delivery, implementation and configuration of LTE and 5G physical layer and stack software.   In 
February 2020, we acquired Holzworth which specializes in supplying signal generators and phase noise analyzers to global aerospace 
and defense companies, the semiconductor industry and government labs.  Approximately 82% and 93% of the Company’s consolidated 
revenues in fiscal years 2020 and 2019, respectively, were derived from commercial customers. The remaining consolidated revenues 
(approximately  18%  and  7%  in  2020  and  2019,  respectively)  were  comprised  of  revenues  from  the  United  States  government 
(particularly the armed forces) and prime defense contractors.

Backlog 

The Company’s consolidated backlog of firm orders to be shipped in the next twelve months was approximately $8.3 million 
at December 31, 2020, compared to approximately $3.8 million at December 31, 2019. The increase in backlog from the prior year is 
due to the addition of Holzworth, as well as an increase in CommAgility backlog.  It is anticipated that the majority of the backlog orders 
at December 31, 2020 will be filled during the current year. The stated backlog is not necessarily indicative of Company revenues for 
any future period nor is a backlog any assurance that the Company will realize a profit from the orders. 

Inventory, Supplies and Manufacturing 

The Company purchases components, devices and subassemblies from a wide variety of sources. The Company’s procurement 
policy requires maintaining adequate levels of raw materials inventory to minimize the Company’s production lead times with third-
party suppliers and to improve the Company’s capacity  to expedite fulfillment of customer orders. Although the procurement team 
focuses its efforts to work closely with its suppliers to avoid adverse effects of shortages or delays in delivery of inventories, delays in 
the future may have an adverse impact on the Company’s operations. For the year ended December 31, 2020, two suppliers accounted 
for 14% of total consolidated inventory purchases, respectively.  For the year ended December 31, 2019, three suppliers accounted for 
18%, 14%, and 10%, respectively, of total consolidated inventory purchases.   

The Company is not party to any long term contracts regarding the deliveries of its supplies and components. It generally 
purchases such items pursuant to written purchase orders of both the individual and blanket variety. Blanket purchase orders usually 
cover the purchase of a larger amount of items at fixed prices for delivery and payment on specific dates. 

For  Boonton  and  Noisecom  products,  the  Company  develops,  designs,  manufactures,  assembles,  calibrates  and  tests  the 
products at our facility in Parsippany, New Jersey. Testing of Boonton and Noisecom products is generally accomplished at the end of 
the manufacturing process and is performed in-house, as are all quality control processes.  

Approximately 46% of Microlab’s revenues are traced to products that are sourced from offshore vendors.   The majority of 
Microlab products that come from offshore suppliers are subject to tariffs.    The impact of tariffs has decreased our consolidated gross 
profit margin by approximately 1%.  The remainder of Microlab products are designed and manufactured by the Company in Parsippany, 
New Jersey.  All Microlab products are tested by the Company in Parsippany, New Jersey.   

CommAgility hardware products are built by contract manufacturers to CommAgility designs and tested either by the contract 
manufacturer or by CommAgility.  Software products are licensed to customers through a system that allows the customer to download 
the software once access has been granted.  

Holzworth products are designed, developed, assembled and tested in our facility in Boulder, Colorado.

Warranty and Service 

The Company typically provides one to three year warranties on all of its products covering both parts and labor. The Company, 
at its option, repairs or replaces products that are defective during the warranty period if the proper preventive maintenance procedures 
have been followed by its customers. 

In cases of defective products the customer typically returns them to the Company’s facility. The Company’s service personnel 
typically repair the defective items and ship them back to the customer. Generally, all servicing is done at the Company’s facility, and 
the Company charges its customers a fee for those service items that are not covered by warranty. If the defective product cannot be 
repaired, the Company typically replaces the product free of charge but unrepairable products are an infrequent occurrence.   

Product Liability Coverage 

The  testing  of  electronic  communications  equipment  and  the  accurate  transmission  of  information  entail  a  risk  of  product 
liability to the Company. Product liability claims could be asserted against the Company by end-users of any of the Company’s products. 
The Company maintains product liability insurance coverage. No claims have been asserted for product liability due to a defective or 
malfunctioning device in the past five years. 

Intellectual Property 

We believe that our intellectual property, including its methodologies, is critical to our success and competitive position. We 
rely on a combination of U.S. and foreign patents, copyrights, trademarks and trade secrets, as well as confidentiality agreements to 
establish and protect our proprietary rights. All employees are subject to the Company’s policies to ensure that all of the Company’s 
intellectual  property  and  business  information  are  maintained  in  confidence.  Key  employees  have  signed  non-disclosure  and  non-
competition agreements.  

Regulation 

Environmental 

The Company’s operations are subject to various federal, state and local environmental laws, ordinances and regulations that 
limit  discharges  into  the  environment,  establish  standards  for  the  handling, generation,  use,  emission,  release,  discharge,  treatment, 
storage  and  disposal  of,  or  exposure  to,  hazardous  materials,  substances  and  waste,  and  require  cleanup  of  contaminated  soil  and 
groundwater. 

At this time, the Company believes that it is in material compliance with all environmental laws, does not anticipate any material 
expenditure to meet current or pending environmental requirements, and generally believes that its processes and products do not present 
any unusual environmental concerns. The Company is unaware of any existing, pending or threatened contingent environmental liability 
that may have a material adverse effect on its ongoing business operations. 

Workplace Safety 

The Company’s operations are  also governed by laws and regulations relating to workplace safety and worker health. The 
Company believes it is in material compliance with these laws and regulations and does not believe that future compliance with such 
laws and regulations will have a material adverse effect on its results of operations or financial condition.  As described in the Recent 
Developments section of Item 7 the Company has implemented additional safety measures for staff working in our facilities as a result 
of the COVID-19 pandemic (also see Pandemic Risks risk factor).   

ITAR and Export Controls 

Certain of the Company’s products may be subject to International Traffic in Arms Regulation, or ITAR. ITAR requires export 
licenses from the U.S. Department of State for products shipped outside the U.S. that have military or strategic applications. Because 
some of the Company’s products could have military or strategic applications, it must ensure its compliance with ITAR. 

In addition, the Company is subject to the Export Administration Regulations, or EAR, which regulates the export of certain 
“dual use” items and technologies and, in some instances, requires a license from the U.S. Department of Commerce in connection with 
sales of the Company’s products.

deployment of wireless technologies around the globe.   

Key 2020 Developments and Financial Results 

Fiscal 2020 was one of the most challenging years in the Company’s recent history.  We began 2020 with an expectation of 
significantly reduced demand from our formerly largest customer for our CommAgility signal processing hardware cards. Accordingly, 
we adjusted our costs and expenses to help offset the impact of the reduced revenues.  These adjustments included headcount reductions 
at our Parsippany N.J. headquarters and various discretionary  cost and  expense reductions.   We also carefully managed our capital 
expenditures  throughout  2020  in  order  to  preserve  liquidity.    Despite  the  expected  reduction  of  the  top  line  for  our  CommAgility 
hardware cards, the Company successfully completed the acquisition of Holzworth on February 7, 2020, which was financed through 
our new term loan facility with Muzinich BDC.  In 2020, Holzworth exceeded our revenue and profitability expectations.   

In March 2020, one month after the close of the Holzworth acquisition, the unforeseen impact of the COVID-19 pandemic 
negatively impacted the Company’s operations and outlook.  Throughout 2020 all of our locations and brands were  challenged with 
travel  bans,  quarantines,  and  shelter-in-place  orders  as  authorities  implemented  measures  to  contain  the  COVID-19  virus.    We 
implemented new cleaning, monitoring and distancing measures to ensure additional procedures and preventative actions were taken in 
accordance with CDC and local government guidelines to help protect the health and well-being of our employees, customers, partners 
and  communities.    The  Company  was  able  to  continue  operations  at  our  manufacturing  facilities  in  Parsippany,  N.J.  and  Boulder, 
Colorado  locations  as    an  “essential  business”  due  to  the  industries  and  customers  we  serve  including  critical  telecommunications 
infrastructure, the U.S. government and numerous global aerospace and defense subcontractors that supply the U.S. government.   

All employees that do not have critical in-person functions have been working remotely since March 16, 2020.   For those 
employees working in our facilities we instituted measures during 2020 including flexible work arrangements, increased distancing of 
workstations, enhanced cleaning protocols, required completion of daily health screening forms for all employees and visitors entering 
our facilities and other safety precautions.   In March 2020 we formed a  COVID-19 task  force made up of various members of the 
management team including operations, finance and sales.  The task force meets regularly to monitor COVID-19 developments and 
ensure the Company reacts quickly to help protect the well-being of its employees.  The task force is also planning our return to normal 
strategy that will be based on data, facts and advice of federal, state and local government leaders in the jurisdictions in which we operate 
as well as medical professionals.  Under our current plans, the Company expects to continue to have the majority of our workforce 
working remotely until May 1, 2021, at which time we will begin a phased re-entry plan, meaning that employees will begin working 
in the office on a limited basis.  However, this timeline may be adjusted based on the facts and circumstances of each jurisdiction in 
which we operate.   

We believe our 2020 financial results were adversely impacted by the COVID-19 pandemic because we experienced a decrease 
in orders related to our Boonton and Noisecom brands as customers closed facilities, slowed orders and instituted capital expenditure 
freezes due to the pandemic.  We also saw a significant decline in Microlab orders throughout our second, third and fourth quarters due 
primarily to large venue project delays and cancellations.  We believe this was caused by the uncertainty of reopening guidelines from 
states, as well as the uncertainty of conventions, college and professional sports, and college and university return to campus schedules 
for students.  Further, we believe certain project timelines and decisions on large private network projects on which our CommAgility 
brand has bids were delayed given the economic uncertainty driven by the pandemic.     

Despite the challenges posed by the COVID-19 pandemic our research and development efforts continued throughout 2020 
most notably CommAgility’s progression on the 5G roadmap and our collaboration with NXP Semiconductors.  Additionally, among 
other product releases, we announced Ultra-Wide Band Microlab products for 5G network deployment and densification and launched 
our new PMX 40 Boonton Power Meter.

On May 4, 2020, the Company received $2.0 million pursuant to a loan under the Paycheck Protection Program (“PPP”) of the 
2020  Coronavirus  Aid,  Relief  and  Economic  Security  Act  (“CARES  Act”)  administered  by  the  Small  Business  Association  (see 
description in Liquidity and Capital Resources below).    The Company’s covered period as defined by the terms of the PPP loan ended 
on October 19, 2020.  The Company used the funds for those purposes as defined under the terms of the PPP loan, most notably payroll 
expenses for our U.S. based employees.  The Company filed for forgiveness in the fourth quarter of 2020 and is awaiting a decision 
from the Small Business Association.  The Company can provide no assurance that the loan will be forgiven in whole or in part.          

The financial information presented herein includes: (i) Consolidated Balance Sheets as of December 31, 2020 and 2019; (ii) 
Consolidated  Statements  of  Operations  and  Comprehensive  Income/(Loss)  for  the  years  ended  December  31,  2020  and  2019;  (iii) 
Consolidated Statement of Changes in Shareholders’ Equity for the years ended December 31, 2020 and 2019; and (iv) Consolidated 
Statements of Cash Flows for the years ended December 31, 2020 and 2019. 

Critical Accounting Policies 

Management’s discussion and analysis of the financial condition and results of operations are based upon the consolidated 
financial statements, which have been prepared in accordance with accounting principles generally accepted in the United States of 
America, or U.S. GAAP. The preparation of these financial statements requires the Company to make estimates and judgments that 
affect the reported amount of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements 
and the reported amount of revenues and expenses for each period. The following represents a summary of the  Company’s critical 
accounting policies, defined as those policies that the Company believes are: (a) the most important to the portrayal of our financial 
condition and results of operations, and (b) that require management’s most difficult, subjective or complex judgments, often as a result 
of  the  need  to  make  estimates  about  the  effects  of  matters  that  are  inherently  uncertain.  Estimates  and  assumptions  are  made  by 
management to assess the overall likelihood that an accounting estimate or assumption may require adjustment. It is reasonably possible 
that these estimates may ultimately differ materially from actual results. See Note 1 in the Notes to the Consolidated Financial Statements 
included elsewhere in this Form 10-K for a description of all of our significant accounting policies. 

Revenue Recognition 

Effective January 1, 2018 the Company adopted Accounting Standards Update (“ASU”) 2014-09, Revenue from Contracts 
with Customers (Topic 606), (“Topic 606”) using the “modified retrospective” method, meaning the standard is applied only to the most 
current period presented in the financial statements.  Topic 606 requires the Company to identify the performance obligations in our 
revenue arrangements – that is, those promised goods and services (or bundles of promised goods or services) that are distinct – and 
allocate the transaction price of the revenue arrangement to those performance obligations on the basis of estimated standalone selling 
prices (“SSP’s”).   

Sales of hardware which include sales of radio frequency solutions, digital signal processing hardware, power meters, analyzers, 
noise/signal generators, phase noise analyzers and other components generally consist of one performance obligation which is satisfied 
upon shipment to the customer.  When contract terms require transfer of control upon delivery at a customer’s location, revenue is 
recognized on the date of delivery.  Sales of hardware to distributors that include a limited right of return are recorded net of expected 
returns.   

Sale of software licenses in the CommAgility brand may involve multiple performance obligations including multiple software 
releases and consultancy services.  In these cases transaction price is allocated to each distinct performance obligation on the basis of 
SSP and revenue is recognized when the distinct performance obligation is satisfied.  The company determines performance obligations 
and SSP’s in arrangements with multiple performance obligations in accordance with Topic 606 which requires significant judgement. 

Services  arrangements  involving  repairs  and  calibrations  of  the  Company’s  products  are  generally  considered  a  single 

performance obligation and revenue is recognized as the services are rendered.   

Certain  software  arrangements  in  the  CommAgility  brand  may  involve  the  transfer  of  software  along  with  significant 
customization  services.    In  these  cases  the  customization  services  and  software  licenses  are  combined  as  one  distinct  performance 
obligation and revenue is recognized over time as the project is completed.  The duration of these performance obligations are typically 
one year or less.

Leases 

We lease office space and certain equipment under non-cancelable lease agreements. Prior to January 1, 2019, we applied the 
accounting guidance in ASC 840, Leases, to our lease agreements. The leases were reviewed for classification as operating or capital 
leases. For operating leases, rent was recognized on a straight-line basis over the lease period. For capital leases, we recorded the leased 
asset with a corresponding liability and amortized the asset over the lease term. Payments were recorded as reductions to the liability 
with an appropriate interest charge recorded based on the then-outstanding remaining liability. 

Effective  January  1,  2019,  we  adopted  ASU  No.  2016-02, Leases  (Topic  842) using  the  modified  retrospective  transition 
method  and  established  our  lease  accounting policy  pursuant  to  this  new  standard.  We  initially  applied  the  transition  provisions  at 
January 1, 2019, which allowed us to continue to apply the legacy guidance in ASC 840 for periods prior to 2019. Based on the new 
guidance, we assess all arrangements, that convey the right to control the use of property, plant and equipment, at inception, to determine 
if it is, or contains, a lease based on the unique facts and circumstances present in that arrangement. For those leases identified, we 
determine  the  lease classification,  recognition,  and  measurement  at  the  lease commencement  date.  For  arrangements  that  contain  a 
lease we: (i) identify lease and non-lease components; (ii) determine the consideration in the contract; (iii) determine whether the lease is 
an  operating  or  financing  lease;  and  (iv)  recognize  lease Right  of  Use  (“ROU”)  assets  and  corresponding  lease liabilities.  
Lease liabilities are recorded based on the present value of lease payments over the expected lease term. The corresponding ROU asset 
is measured from the initial lease liability, adjusted by (i) accrued or prepaid rents; (ii) remaining unamortized initial direct costs and 
lease incentives; and (iii) any impairments of the ROU asset. The interest rate implicit in our lease contracts is typically not readily 
determinable and as such, we use our incremental borrowing rate based on the information available at the lease commencement date, 
which represents an internally developed rate that would be incurred to borrow, on a collateralized basis, over a similar term, an amount 
equal to the lease payments in a similar economic environment. 

Business Combinations 

The Company uses the acquisition method of accounting for business combinations which requires the tangible and intangible 
assets acquired and liabilities assumed to be recorded at their respective fair market value as of the acquisition date. Goodwill represents 
the  excess  of  the  consideration  transferred  over  the  fair  value  of  the  net  assets  acquired.  The  fair values  of  the  assets  acquired  and 
liabilities assumed are determined based upon the Company’s valuation and involves making significant estimates and assumptions 
based  on  facts  and  circumstances  that  existed  as  of  the  acquisition  date.  The  Company  uses  a  measurement  period  following  the 
acquisition date to gather information that existed as of the acquisition date that is needed to determine the fair value of the assets 
acquired and liabilities assumed. The measurement period ends once all information is obtained, but no later than one year from the 
acquisition date. 

Valuation of Goodwill 

Goodwill represents the excess of  the aggregate purchase price over the fair value of the net assets acquired in a purchase 
business combination.  Goodwill is evaluated for impairment annually, or more frequently if events occur or circumstances change that 
would indicate that goodwill might be impaired, by first performing a qualitative evaluation of events and circumstances impacting the 
reporting unit to determine the likelihood of goodwill impairment.  Based on that qualitative evaluation, if we determine it is more likely 
than not that the fair value of a reporting unit exceeds its carrying amount, no further evaluation is necessary.  Otherwise we perform a 
quantitative impairment test.   

The Company has three reporting units with goodwill – Holzworth, Microlab and CommAgility.  The Company performed a 
qualitative assessment in the fourth quarter of 2020 of each reporting unit.  The qualitative assessment of Holzworth and Microlab did 
not indicate any impairment of goodwill.  As a result of declining  demand of CommAgility’s signal processing hardware  cards from a 
single customer and the particularly high uncertainty associated with the ultimate trajectory of the pandemic, including the degree to 
which governments would continue to restrict business and personal activities, and the impact that uncertainty has on   the growth of 
new software license and services revenue to offset the signal processing hardware sales decline, the Company performed a quantitative 
impairment test of the goodwill of the CommAgility reporting unit.   

10 

 
 
 
 
 
 
 
  
 
 
 
For goodwill impairment testing using the quantitative approach, the Company estimates the fair value of the selected reporting 
unit using the income approach and the market approach.  Fair value under the income approach is derived primarily through the use of 
a discounted cash flow model based on our best estimate of amounts and timing of future revenues and cash flows and our most recent 
business and strategic plans.  Fair value under the market approach is derived by applying a multiple to our best estimate of future 
revenue.  The Company applies equal weighting to the income approach and the market approach to arrive at an estimated fair value. 
The estimated fair value is compared to the carrying value of the reporting unit, including goodwill. If the fair value of the reporting 
unit exceeds the carrying value, no impairment charge is recorded.  If the carrying value of the reporting unit exceeds the fair value an 
impairment charge is recorded to goodwill in the amount by which carrying value exceeds fair value.   Both the income approach and 
market approach require judgmental assumptions about projected revenue growth, future operating margins, discount rates and terminal 
values over a multi-year period. There are inherent uncertainties related to these assumptions and management’s judgment in applying 
them to the analysis of goodwill impairment. While the Company believes it has made reasonable estimates and assumptions to calculate 
the fair value of its reporting units, it is possible a material change could occur.  

In the fourth quarter of 2020, the Company recorded a goodwill impairment charge of $4.7 million related to the CommAgility 
reporting  unit.    The  non-cash  impairment  charge  was  due  to  a  number  of  factors  that  arose  as  part  of  our  quantitative  assessment, 
including an assessment of our historical results and the significant decline in hardware sales in 2020, the difficulty of predicting future 
customer  demand,  the  uncertainty  of  future  sales  of  4G hardware cards,  the  uncertainty  of  the  growth  of  5G  software  and  services 
revenues  due  to  the  early  stages  of  5G  adoption  for  new  technology  and  expectations  for  5G  deployments,  the  uncertainty  of  the 
continued  future  impacts  of  the  COVID  19  pandemic  on  customer  spending,  and  the  potential  for  a  more  prolonged  recovery  for 
enterprise spending and longer-term investment.   Despite the asset impairment charge, the Company believes the markets in which 
CommAgility operates, specifically LTE and 5G private networks, have long-term growth potential and the Company is committed to 
growing the revenue and profitability of the reporting unit.          

Due to the many variables inherent in the estimation of a reporting unit’s fair value and the relative size of our recorded goodwill, 
differences in assumptions may have a material effect on the results of our impairment analysis.  After recording the 2020 goodwill 
impairment charge, the Company’s consolidated goodwill balance as of December 31, 2020 was comprised of $1.4 million related to 
the Microlab reporting unit, $6.0 million related to the Holzworth reporting unit and $4.1 million related to the CommAgility reporting 
unit.   

As  of  December  31,  2019,  the  Company’s  consolidated  goodwill  balance  of  $10.1  million  was  comprised  of  $1.4  million 
related to the Microlab reporting unit and $8.7 million related to the CommAgility reporting unit.  Management’s qualitative assessment 
performed in the fourth quarter of 2019 did not indicate any impairment of goodwill.  

Intangible and Long-lived Assets 

Intangible assets include acquired technology, patents, non-competition agreements, customer relationships and tradenames.  
Intangible assets with finite lives are amortized using the straight-line method over the estimated economic lives of the assets, which 
range from three to twelve years. Long-lived assets, including intangible assets with finite lives, are reviewed for impairment whenever 
events  or  changes  in  circumstances  indicate  that  the  carrying  amount  of  such  assets  may  not  be  recoverable.  Determination  of 
recoverability is based on an estimate of undiscounted future cash flows resulting from the use of the asset and its eventual disposition. 
Measurement of an impairment loss for long-lived assets that management expects to hold and use is based on the estimated fair value 
of the asset. Long-lived assets to be disposed of are reported at the lower of carrying amount or estimated fair value less costs to sell.  
The estimated useful lives of intangible and long-lived assets are based on many factors including assumptions regarding the effects of 
obsolescence, demand, competition and other economic factors, expectations regarding the future use of the asset, and our historical 
experience with similar assets. The assumptions used to determine the estimated useful lives could change due to numerous factors 
including product demand, market conditions, technological developments, economic conditions and competition.  Intangible assets 
determined to have indefinite useful lives are not amortized but are tested for impairment annually and more frequently if events occur 
or circumstances change that indicate an asset may be impaired.   

Income taxes 

The  Company  records  deferred  taxes  in  accordance  with  ASC  740,  “Accounting  for  Income  Taxes.”  ASC  740  requires 
recognition of deferred tax assets and liabilities for temporary differences between tax basis of assets and liabilities and the amounts at 
which they are carried in the financial statements, based upon the enacted rates in effect for the year in which the differences are expected 
to reverse. The Company establishes a valuation allowance when necessary to reduce deferred tax assets to the amount expected to be 
realized. The Company periodically assesses the value of its deferred tax assets and determines the necessity for a valuation allowance. 

Realization of the Company’s deferred tax assets is dependent upon the Company generating sufficient taxable income in the 
appropriate  tax  jurisdictions  in  future  years  to  obtain  benefit  from  the  reversal  of  net  deductible  temporary  differences  and  from 
11 

 
 
 
 
  
 
 
 
 
utilization of net operating losses.  The amount of deferred tax assets considered realizable is subject to adjustment in future periods if 
estimates of future taxable income are changed.  

Uncertain tax positions 

Under ASC 740, the Company must recognize and disclose uncertain tax positions only if it is more-likely-than-not that the 
tax  position  will  be  sustained  on  examination  by  the  taxing  authority,  based  on  the  technical  merits  of  the  position.  The  amounts 
recognized in the financial statements attributable to such position, if any, are recorded if there is a greater than 50% likelihood of being 
realized upon the ultimate resolution of the position. 

The Company has analyzed its filing positions in all of the jurisdictions where it is required to file income tax returns. As of 
December 31, 2020 and 2019, the Company has identified its federal tax return and its state tax return in New Jersey as “major” tax 
jurisdictions, as defined in ASC 740, in which it is required to file income tax returns. As a result of our acquisition of Holzworth on 
February 7, 2020, Colorado is a “major” tax jurisdiction for fiscal year 2020.   Additionally, the Company has identified the United 
Kingdom as a “major” tax jurisdiction as of December 31, 2020 and 2019.  Based on the evaluations noted above, the Company has 
concluded that there are no significant uncertain tax positions requiring recognition or disclosure in its consolidated financial statements. 

Based on a review of tax positions for all open years and contingencies as set out in the Company’s Notes to the consolidated 
financial statements, no reserves for uncertain income tax positions have been recorded pursuant to ASC 740 during the years  ended 
December 31, 2020 and 2019, and the Company does not anticipate that it is reasonably possible that any material increase or decrease 
in its unrecognized tax benefits will occur within the next twelve months. 

Stock-based compensation 

The Company follows the provisions of ASC 718, “Compensation - Stock Compensation” which requires that compensation 
expense  be  recognized  based on  the  fair value of  equity  awards  on  the  date  of  grant.  The  fair  value  of  restricted  share  awards  and 
restricted stock unit awards is determined using the market value of our common stock on the date of the grant.  The fair value of stock 
options at the date of grant is estimated using the Black-Scholes option pricing model. When stock options are granted, the Company 
takes  into  consideration  guidance  under  ASC  718  and  SEC  Staff  Accounting  Bulletin  No.  107  (SAB  107)  when  determining 
assumptions. The expected option life is derived from assumed exercise rates based upon historical exercise patterns and represents the 
period of time that options granted are expected to be outstanding. The expected volatility is based upon historical volatility of our shares 
using daily price observations over an observation period that approximates the expected life of the options. The risk-free rate is based 
on the U.S. Treasury yield curve rate in effect at the time of grant for periods similar to the expected option life.  The Company accounts 
for forfeitures for all equity awards when they occur.   

Management estimates are necessary in determining compensation expense for stock options with performance-based vesting 
criteria. Compensation expense for this type of stock-based award is recognized over the period from the date the performance conditions 
are  determined  to  be  probable  of  occurring  through  the  date  the  applicable  conditions  are  expected  to  be  met.  If  the  performance 
conditions are not considered probable of being achieved, no expense is recognized until such time as the performance conditions are 
considered  probable  of  being  met,  if  ever.  Management  evaluates  whether  performance  conditions  are  probable  of  occurring  on  a 
quarterly basis. 

Inventories and Inventory Valuation 

Inventories are stated at the lower of cost (average cost) or net realizable value. The Company reviews inventory for excess 

and obsolescence based on best estimates of future demand, product lifecycle status and product development plans. 

Allowances for doubtful accounts 

The Company maintains allowances for doubtful accounts for estimated losses resulting from the inability of its customers to 
make required payments. A key consideration in estimating the allowance for doubtful accounts has been, and will continue to be, our 
customer’s payment history and aging of our accounts receivable balance. 

Impairment of long-lived assets 

Long-lived assets are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount 
of such assets may not be recoverable. Determination of recoverability is based on an estimate of undiscounted cash flows resulting 
from the use of the assets and their eventual disposition. Measurement of an impairment loss for long-lived assets that management 

12 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
expects to hold for sale is based on the fair value of the assets. Long-lived assets to be disposed of are reported at the lower of carrying 
amount or fair value less costs to sell. 

Warranties 

The Company generally offers standard warranties against product defects.  We estimate future warranty costs to be incurred 

based on historical warranty claims experience including estimates of material and service costs over the warranty period.

Consolidated revenues declined $7.2 million or 14.7% due primarily to lower sales in our RBS product group of our digital 
signal processing hardware cards.  Sales of the RBS hardware cards declined $10.7 million from the prior year.  The loss was only 
partially offset by higher sales of our higher margin RBS software and services.  Additionally, the acquisition of Holzworth on February 
7, 2020 contributed $8.8 million in revenue to our T&M product group in 2020.  This acquisition helped offset declines in our Boonton 
and Noisecom brands, which experienced lower sales from the prior year primarily due to the impacts of the COVID-19 pandemic on 
capital expenditure spending of our customers.  Our RFC product group revenue declined $4.2 million or 19.1% due to lower sales of 
our  passive  components  as  wireless  carriers  delayed  buildouts  and  upgrades  of  in-building  wireless  systems  due  to  the  COVID-19 
pandemic.

Consolidated gross profit declined $1.3 million or 5.9% from the prior year.  The decrease was primarily due to lower volumes 
at our RBS and RFC product groups which were only partially offset by the revenue and gross margin contribution of Holzworth.  Our 
gross margin as a percentage of sales increased from 45.6% to 50.2% due to the higher margin software and services sales at our RBS 
product group, the contribution of higher margin product sales from Holzworth and cost savings initiatives at our RFC product group.

Research and development expenses increased $472,000 or 8% from the prior year period due to the acquisition  of Holzworth 
which contributed $545,000 in expenses in 2020 and an increase in third party research and development expenses of $500,000 from 
the prior year primarily related to 5G roadmap development and product development in our Boonton brand.  The increase was partially 
offset  by  declines  in  salaries  and  benefits  and  other  discretionary  expenses  of  approximately  $600,000  due  primarily  to  expense 
reductions including headcount reductions.   

Sales and marketing expenses decreased $722,000 from the prior year period due to a decline in salaries and benefits due to 
expense reduction initiatives including headcount reductions, a decline in external  and internal commissions due to lower order and 
sales volumes and declines in marketing expenses and travel expenses caused by the COVID-19 pandemic.  These decreases from the 
prior year period totaled $1.9 million and were partially offset by the acquisition of Holzworth which contributed $1.2 million in sales 
and marketing expenses in 2020.   

General and administrative expenses decreased $267,000 as increases from the addition of Holzworth of $795,000  and the 
recognition of $255,000 of deferred Form S-3 costs were offset by decreases in merger and acquisition expenses and other discretionary 
expenses that declined due to expense reduction initiatives.   

The goodwill impairment charge of $4.7 million relates to our CommAgility reporting unit and  is the result of our annual 
goodwill  impairment  analysis  which  indicated  that  the  estimated  fair  value  of  the  CommAgility  reporting  unit  was  lower  than  the 
carrying value as of the valuation date.   

The loss on change in fair value of contingent consideration of $1.1 million relates primarily to the earn-out consideration to 
be paid in connection with the Holzworth acquisition for the 2020 calendar year.  Our estimate of the earn-out payment was increased 
from our original estimate recorded at the time of the acquisition due to the improved financial results of Holzworth.     

 Other income/expense 

Other income increased $189,000 due primarily to an increase in gains on sales of assets and foreign currency exchange gains.       

Interest Expense 

Interest expense increased $680,000 due to the interest on our new term loan facility with Muzinich and the amortization of 

debt issuance costs related to securing the new term loan facility.   

Tax  

The Company’s consolidated tax benefit decreased $563,000 from the prior year due primarily to taxable income in the US 

jurisdiction driven primarily by the acquisition of Holzworth.

Net Loss  

Net  loss  increased  from  $414,000  to  $8.1  million  due  primarily  to  lower  gross  profit  on  lower  revenues,  the  goodwill 
impairment  charge  recorded  at  the  CommAgility  reporting  unit,  recognition  of  the  loss  on  change  in  fair  value  of  contingent 
consideration and the increase in interest expense due to our new term loan.    

 Liquidity and Capital Resources 

The Company has two credit facilities – an asset based revolving loan which is subject to a  borrowing base calculation (as 
defined) with Bank of America, N.A. (the “Credit Facility” or the “Revolver”) and a term loan facility  dated February 7, 2020 with 
Muzinich  BDC  Inc.  (“Muzinich”)  to  finance  the  Holzworth  Acquisition  in  the  amount  of  $8.4  million  (the  “Term  Loan  Facility”).  
Additionally, on May 4, 2020 the Company received $2.0 million pursuant to a loan under the PPP of the 2020 CARES Act administered 
by the Small Business Association.   

Revolver 

On February 16, 2017 the Company entered into the Credit Facility which provided for a term loan in the aggregate principal 
amount of $760,000 (the “BOA Term Loan”) and the Revolver which has a maximum availability of up to $9.0 million subject to  a 
borrowing base calculation applicable to the Company’s assets.  The proceeds of the Term Loan and Revolver were used to finance the 
acquisition of CommAgility.  On February 26, 2019 the Company entered into Amendment No. 3 to the Credit Facility which extended 
the term of the Revolver to March 31, 2020, and on November 8, 2019 the Company entered into Amendment No. 4 to the Credit 
Facility which extended the maturity date of the Term Loan to March 31, 2020 to coincide with that of the Revolver.  On February 7, 
2020, in connection with the Holzworth acquisition, the Company entered into Amendment No. 5 to the Credit Facility which, inter alia, 
extended the Revolver maturity date to March 31, 2023.  Additionally, the Company prepaid the remaining principal balance of  the 
BOA Term Loan in the amount of $340,000.      

By entering into Amendment No. 5, Holzworth and CommAgility, became borrowers under the Credit Facility.  The obligations 
of the borrowers under the Credit Facility are guaranteed by Wireless Telecom Group, Ltd.  CommAgility Limited and Wireless Telecom 
Group, Ltd. are both wholly owned subsidiaries of the Company.   

 Amendment  No.  5  (a)  modified  certain  provisions  of  the  Credit  Facility  to  accommodate  the  Holzworth  acquisition,  the 
Company’s incurrence of the Term Loan Facility and the granting of the related liens and security interests, (b) subject to the satisfaction 
of certain conditions precedent, made available to CommAgility an asset based revolving loan, subject to a borrowing base calculation 
applicable to CommAgility’s assets, of up to a maximum availability of $5.0 million (the “UK Revolver Commitment”), (c) reduced the 
interest rate margin applicable to revolving loans made under the Credit Facility from a range of 2.75% to 3.25% to a range of 2.00% to 
2.50%, based on the Borrowers’ Fixed Charge Coverage Ratio (as defined in the Credit Facility) of the most recently completed fiscal 
quarter, (d) extended the Revolver Termination Date to March 31, 2023 and (e) conditioned the Borrowers’ ability to make certain debt 
payments under the Term Loan Facility (described below) upon compliance with a liquidity test.   

Effectiveness  of  Amendment  No.  5  was  conditioned  upon, among  other  things,  the  prepayment of  the  remaining  principal 
balance ($304,000) of the $760,000 term loan made available under the Credit Facility and the payment of a closing fee in the amount 
of $25,000.  The borrowers satisfied all such conditions on February 7, 2020.   

On May 4, 2020, the Company, its subsidiaries and Bank of America entered into Amendment No. 6 which, among other 
things, amended the definition of “Debt” to include the PPP loan as long as the proceeds are used for allowable purposes under the 
CARES Act and the Company promptly submits an application for forgiveness and substantially all of the loan is forgiven. 

On February 25, 2021, the Company, its subsidiaries and Bank of America entered into Amendment No. 7 which revised the 
Credit Facility to accommodate the changes to the deferred purchase price payments to and notes with the Holzworth sellers as described 
below and provided Bank of America’s consent to the Company entering into the Muzinich Second Amendment, as described below.  
In all other material respects, the Credit Facility remains unchanged. 

Any exercise of remedies by Bank of America, N.A. under the Credit Facility is subject to compliance with the intercreditor 
agreement entered into at the closing of Amendment No. 5 among the Company, Muzinich, as lender under the Term Loan Facility, and 
Bank of America, N.A.

Term Loan Facility 

In  connection  with  the  Holzworth  acquisition,  on  February  7,  2020,  the  Company,  as  borrower,  and  its  subsidiaries,  as 
guarantors, and Muzinich, entered into the Term Loan Facility, which provides for a term loan in the principal amount of $8.4 million 
(“Initial Term Loan”), all of which was used to fund the cash portion of the purchase price and related debt and closing fees for the 
Holzworth acquisition.   Principal payments on the Initial Term Loan are $21,000 per quarter with a balloon payment at maturity on 
February 7, 2025. The Term Loan Facility includes an upfront fee of 2.50% of the aggregate principal amount.  The Term Loan Facility 
provides  for  an  additional  $11.6  million  term  loan  (the  “Second  Term  Loan”)  to  be  used  for  a  second  unannounced  acquisition 
opportunity (the “Additional Acquisition”). There can be no assurance that the Additional Acquisition will be completed.  In the event 
the Additional Acquisition is completed, the Second Term Loan will be made available to the Company on the same terms and conditions 
as the Initial Term Loan, including interest rate, amortization schedule and financial covenants, subject to the payment of an additional 
upfront fee and satisfaction of customary conditions to funding. 

The Company may prepay the Initial Term Loan at any time.  Prepayments made prior to (a) February 7, 2022 are subject to a 
prepayment premium in the amount of 2.0% of the prepaid principal amount and (b) February 7, 2023 are subject to a prepayment 
premium in the amount of 1.0% of the prepaid principal amount.  The Company is required to make prepayments of the Initial Term 
Loan with the proceeds of certain asset dispositions, insurance recoveries and extraordinary receipts, subject to specified reinvestment 
rights.  The Company is also required to make prepayments of the Initial Term Loan upon the issuance of certain indebtedness  and to 
make  an  annual  prepayment  based  upon  the  Company’s  excess  cash  flow.    Mandatory  prepayments  with  asset  sale,  insurance  or 
condemnation proceeds and excess cash flow may be made without penalty.  Mandatory prepayments with the proceeds of indebtedness 
are subject to the same prepayment penalties as are applicable to voluntary prepayments. 

The Term Loan Facility is secured by liens on substantially all of the Company’s and its subsidiaries’ assets including a pledge 
of the equity interests in the Company’s subsidiaries. The Term Loan Facility contains customary affirmative and negative covenants 
for  a  transaction  of  this  type,  including,  among  others,  the  provision  of  annual,  quarterly  and  monthly  financial  statements  and 
compliance certificates, maintenance of property, insurance, compliance with laws and environmental matters, restrictions on incurrence 
of indebtedness, granting of liens, making investments and acquisitions, paying dividends, entering into affiliate transactions and asset 
sales. In addition, the Company must maintain certain financial covenants typical for this type of arrangement, including a consolidated 
leverage ratio, a consolidated fixed charge coverage ratio and minimum liquidity of its foreign subsidiaries.  The consolidated leverage 
ratio is defined as the ratio of total consolidated indebtedness, as defined, to consolidated EBITDA, as defined.  Prior to Amendment 2 
described below, the required leverage ratio started at 4.75 to 1.0 for the twelve month periods ended March 31, 2020 and June 30, 2020, 
and decreased in various increments to 3.75 to 1.0 for the twelve months ended December 31, 2020, 2.75 to 1.0 for the twelve months 
ended December 31, 2021 and 2.0 to 1.0 for the twelve months ended December 31, 2022 and thereafter.  The consolidated fixed charge 
coverage ratio is the ratio of consolidated EBITDA, as defined, less consolidated capital expenditures and cash income taxes paid to 
consolidated fixed charges, as defined, calculated on a twelve-month basis.  The consolidated fixed charge coverage ratio for the twelve 
month periods ended March 31, 2020, June 30 2020 and September 30, 2020 must be 1.35 to 1 and increases in various increments on 
a quarterly basis to 1.5 to 1.0 for the twelve month period ended December 31, 2020 and 2021, and to 1.75 to 1.0 for the 12 months 
ending December 31,  2022 and thereafter.  Lastly, the Company must maintain minimum liquidity, defined as cash and availability 
under the UK borrowing base, as defined, of $1.0 million over any trailing four-week period until such time as the foreign subsidiary 
has positive EBITDA, as defined, for three consecutive quarters and the Holzworth deferred purchase price has been paid in full.  The 
Term Loan Facility also provides for a number of events of default, including, among others, nonpayment, bankruptcy, inaccuracy of 
representations and warranties, breach of covenant, change in control, entry of final judgement or order, breach of material contracts, 
and as long as the Company’s consolidated leverage ratio is greater than 1.0 to 1.0 (as calculated in accordance with the terms of the 
Term Loan Facility), the cessation of service of any two of Tim Whelan, Michael Kandell or Daniel Monopoli as Chief Executive 
Officer, Chief Financial Officer or Chief Technology Officer, respectively, of the Company without acceptable replacements within 60 
days. Any exercise of remedies by Muzinich is subject to compliance with the intercreditor agreement entered into at the closing of the 
Term Loan Facility among the Company, Muzinich and Bank of America, N.A., as lender under the Credit Facility referenced below. 

On  May  4,  2020,  the  Company  entered  into  the  First  Amendment  to  the  Term  Loan  Facility  which,  among  other  things, 
amended the definition of “Indebtedness” to include the PPP loan as long as the proceeds are used for allowable purposes under the 
CARES Act, the receipt of the loan does not violate the Credit Facility and the Company submits an application for forgiveness and 
substantially all of the loan is forgiven. 

On  February  25,  2021,  the  Company,  its  subsidiaries  and  Muzinich  entered  into  the  Second  Amendment  to  the  Credit 
Agreement and Limited Waiver (“Amendment 2”) in which Muzinich agreed to waive the Company’s obligation to comply with the 
consolidated leverage ratio and fixed charge coverage ratio financial covenants in the Term Loan Facility for the fiscal quarter ending 
December 31, 2020. We were not in compliance with such covenants primarily as a result of the impact the COVID-19 pandemic had 

16 

 
 
 
 
on our consolidated financial results.  Amendment 2, among other things, amended the definition of consolidated EBITDA to include 
certain cash tax benefits related to our UK tax jurisdiction and reduced our consolidated leverage ratio for the twelve month periods 
ended September 30, 2021 from 3.00 to 2.75, December 31, 2021 from 2.75 to 2.25, March 31, 2022 from 2.50 to 2.00 and June 30 , 
2022 from 2.25 to 2.00.  Additionally, the interest rate margin was increased from 7.25% to 9.25% effective January 1, 2021 and will 
step down to 8.50% and 7.25% upon the Company achieving consolidated EBITDA on a trailing twelve-month basis of $4.0 million 
and $6.3 million, respectively.  Muzinich and the Company also agreed on an excess cash flow payment of $428,000 and Muzinich 
provided consent for the Company to change the deferred purchase price payments to and enter into notes with the Holzworth sellers in 
the amount of $750,000, as described below. 

PPP Loan 

On May 4, 2020, the Company received $2.0 million pursuant to a loan from Bank of America N.A. under the PPP program of 
the 2020 CARES Act administered by the Small Business Association (“SBA”).  The loan has an interest rate of 1% and a term of 24 
months. A repayment schedule has not yet been provided by Bank of America.  Accordingly, the full amount of the term loan has been 
shown as due in May 2022.  Funds from the loan may only be used for certain purposes, including payroll, benefits, rent and utilities. 
The CARES Act and the PPP provide a mechanism for forgiveness of up to the full amount of the loan upon application to the SBA for 
forgiveness by the Company.  The  loan is evidenced by a promissory note, which contains customary events of default relating to, 
among other things, payment defaults and breaches of representations and warranties. The Company may prepay the loan at any time 
prior to maturity with no prepayment penalties.  The Company applied for forgiveness of the loan in the fourth quarter of 2020 and has 
elected to account for the loan in accordance with ASC 470 Debt unless and until such time that forgiveness is approved by the SBA.  
The Company can provide no assurance that the loan will be forgiven in whole or in part.          

Sources and Uses of Cash 

As of December 31, 2020, the Company’s consolidated cash balance was $4.9 million as compared to $4.2 million as of the 
prior year.  No funds were drawn on our Revolver and we had availability under our borrowing base of $7.2 million as of December 31, 
2020.  The outstanding balances of our Term Loan Facility and PPP Loan were $8.3 million and $2.0 million, respectively.   

Our primary sources of cash were the receipt of the Term Loan Facility in the amount of $8.4 million which was used to pay 
the cash portion of the Holzworth purchase price and related debt and transaction fees, receipt of the PPP loan in the amount of $2.0 
million which was used to fund operating payroll during the covered period and cash generated from operations of $3.0 million which 
was primarily the result of a decrease in net working capital from the prior year (net of the impact of the Holzworth acquired working 
capital).   

Operating Activities 

Cash from operations increased from $80,000 in the prior year to $3.0 million in 2020.  The increase was due to cash generated 
from a decrease in working capital from the prior year, net of the acquired working capital of Holzworth.  The working capital decrease 
was primarily due to receipt of the UK tax refund and increased accrued expenses.   

Investing Activities 

Cash used by investing activities increased from $818,000 in the prior year to $8.6 million in 2020 which includes $8.2 million 
of cash paid related to the Holzworth acquisition in February 2020 representing $7.2 million in cash paid at close, $750,000 related to 
the first deferred purchase price payment,  and $600,000 in indemnification holdback payments offset by a $292,000 working capital 
adjustment in the Company’s favor.  Capital expenditures were flat at $364,000 in 2020 as compared to $392,000 in the prior year.   

 Financing Activities  

Cash from financing activities increased from a use of cash of $212,000 in the prior year to cash generated of $6.3 million due 

primarily to the receipt of the Term Loan Facility, net of debt issuance costs and the receipt of the PPP loan.

Holzworth Deferred Purchase Price and Earnout 

On  February  19,  2021,  the  Company  entered  into  the  Second  Amendment  with  Holzworth  and  Sellers.    The  Second 
Amendment, among other things, converts the second deferred purchase price of $750,000 into unsecured seller notes with interest at 
an annual rate of 6.5% starting from April 1, 2021 until final payment. The payment date has been changed from March 31, 2021 to 
three equal installments of $250,000, plus accrued interest, due on July 1, 2021, October 1, 2021 and January 1, 2022. 

Additionally, the parties amended the payment dates of the earnout consideration. The payment date of the first earnout payment 
based on the financial results of the calendar year ended 2020 (“Year 1 Earnout”) has been amended from March 31, 2021 to (i) six (6) 
equal quarterly installments of 10% of the Year 1 Earnout payable on the last business day of each calendar quarter between June 30, 
2021 and September 30, 2022 and (ii) one (1) installment payment equal to 40% of the Year 1 Earnout on December 31, 2022. The Year 
1 Earnout is payable in cash or shares of the Company’s common stock based on the 90 trading day volume weighted average price 
immediately preceding final determination of the Year 1 Earnout or $2.19 per share.  The estimated payment for the Year 1 Earnout is 
$3.4 million.  The payment date for the second earnout payment which is based on the financial results of the calendar year ended 2021 
(“Year 2 Earnout”) has been amended from March 31, 2022 to four equal quarterly installments payable on the last business day of each 
calendar quarter between March 31, 2022 and December 31, 2022. The Year 2 Earnout is also payable in cash or stock at the Company’s 
discretion. The aggregate earnout payments of the Year 1 Earnout and the Year 2 Earnout cannot exceed $7.0 million. 

The parties also amended the provisions with respect to restrictions on transfer to adjust for the change in timing of earnout 
payments,  as  described  above.  Finally,  the  parties  added  a  requirement  that  any  earned  but  unpaid  earnout  consideration  will  be 
accelerated in the event the Company desires to enter into a material asset or equity acquisition in the future. 

We expect borrowings available to us under our Credit Facility, our existing cash balance and cash generated by operations 
will be sufficient to meet our liquidity needs for the next twelve months.  Our ability to meet our cash requirements will depend on our 
ability  to  generate  cash  in  the  future,  which  is  subject  to  general  economic,  financial,  competitive,  legislative, regulatory  and other 
factors that are beyond our control, including the COVID-19 pandemic and the significantly decreased demand from our formerly largest 
customer for our digital signal processing cards and ongoing  low sales to that customer due to  reduced demand, as well as delayed 
decisions on large private network projects that we believe are caused by economic uncertainty driven by the pandemic. We expect these 
uncertainties to extend to our business in the first two quarters of 2021, as sales, deliveries, cash collections, our supply chain and our 
business partners could be adversely affected.   

The Company expects to realize tax benefits in future periods due to the available net operating loss carryforwards resulting 
from the disposition of a former wholly owned subsidiary in 2010. Accordingly, future taxable income is expected to be offset by the 
utilization of operating loss carryforwards and as a result will increase the Company’s liquidity as cash needed to pay federal and state 
income taxes will be substantially reduced.  Additionally, CommAgility benefits from a research and development deduction which 
significantly reduces the cash needed to pay taxes in the UK.    

On August 27, 2018 the Company filed a shelf registration statement on Form S-3 which was declared effective on September 
17, 2018.  The Form S-3 will permit the Company to issue and sell, from time to time, up to $40 million in aggregate value of shares of 
its common stock through one or more methods of distribution,  subject to applicable SEC limits  on the value of securities that  the 
Company, as a smaller reporting company, may sell during an applicable period, market conditions, and the Company’s capital desires 
and needs.   

The terms of any offering of the Company’s common stock, and the intended use of the net proceeds resulting therefrom, will 
be  established  at  the  times  of  the  offerings and  will be  described  in  prospectus  supplements  filed  with  the  SEC  at  the  times  of  the 
offerings.  The shelf registration statement is intended to provide financial flexibility to access capital in a competitive and expeditious 
manner when market conditions are appropriate.  The shelf registration statement expires on September 17, 2021.  The Company intends 
to update the registration statement prior to expiration.     

Purchase  obligations  consist  of  inventory  that  arises  in  the  normal  course  of  business  operations.  Future  obligations  and 

commitments as of December 31, 2020 consisted of the following:

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM 
Wireless Telecom Group, Inc. 

To the Board of Directors and Shareholders 
Wireless Telecom Group, Inc. 
Parsippany, NJ 

Opinion on the Consolidated Financial Statements 
We have audited the accompanying consolidated balance sheets of Wireless Telecom Group, Inc. (the “Company”) as of December 31, 
2020 and 2019, and the related consolidated statements of operations and comprehensive income/(loss), changes in shareholders’ equity 
and cash flows for each of the two years in the period ended December 31, 2020, and the related notes (collectively referred to as the 
“consolidated financial statements”). In our opinion, the consolidated financial statements present fairly, in all material respects, the 
financial position of the Company as of December 31, 2020 and 2019, and the results of its operations and its cash flows for each of the 
two years in the period ended December 31, 2020, in conformity with accounting principles generally accepted in the United States of 
America. 

Basis for Opinion 
These consolidated financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion 
on the Company’s consolidated financial statements based on our audits. We are a public accounting firm registered with the Public 
Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Company in 
accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission 
and the PCAOB. 

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit 
to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud.  
The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting.  As part 
of our audits, we are required to obtain an understanding of internal control over financial reporting, 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.  

Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error 
or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding 
the amounts and disclosures in the consolidated financial statements. Our audits also included evaluating the accounting principles used 
and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. 
We believe that our audits provide a reasonable basis for our opinion. 

Critical Audit Matters 

The critical audit matters communicated below are matters arising from the current period audit of the consolidated financial statements 
that were communicated or required to be communicated to the audit committee and that (1) relates to accounts or disclosures that are 
material to the consolidated financial statements and (2) involved our especially challenging, subjective, or complex judgments. The 
communication of critical audit matters does not alter in any way our opinion on the consolidated financial statements, taken as a whole, 
and we are not, by communicating the critical audit matters below, providing separate opinions on the critical audit matters or on the 
accounts or disclosures to which they relate. 

Goodwill Impairment Assessment 
As described in Notes 1 and 6 to the consolidated financial statements, the Company’s consolidated goodwill balance was $11.5 million 
as of December 31, 2020. Management evaluates goodwill, at the reporting unit level, for impairment annually during the fourth quarter, 
or  more  frequently,  if  events occur  or  circumstances  change  which  would  indicate  that goodwill  might be  impaired. As  a  result  of 
declining demand of signal processing hardware from a single customer in one of the Company’s reporting units, CommAgility, as well 
as  the  high  uncertainty  associated  with  the  ultimate  trajectory  of  the  COVID-19  pandemic,  management  performed  a  quantitative 
analysis of the fair value of the CommAgility reporting unit and determined its fair value was below its carrying value. Fair value of the 
reporting unit was estimated using a combination of the income approach and the market approach. The Company used a discounted 
cash flow model for the income approach valuation method and the guideline public company and guideline transaction methods for the 
market approach valuation method. The determination of the fair value of the reporting unit required management to make significant 
estimates  and  assumptions  related  to  projected  revenue  growth,  future  operating  margins,  discount  rates  and  terminal  values.  As 
disclosed by management, changes in these estimates and assumptions could have a significant impact on the fair value of the reporting 
unit, the amount of the goodwill impairment, or both. As a result of the quantitative impairment analysis discussed above, the Company 
recorded a goodwill impairment of $4.7 million during the year ended December 31, 2020.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM 
Wireless Telecom Group, Inc. 

The principal considerations for our determination that performing procedures relating to the goodwill impairment assessment of the 
CommAgility reporting unit is a critical audit matter are (i) the significant judgment by management when developing the fair value 
measurement  of  the  reporting  unit;  (ii)  a  high  degree  of  auditor  judgment,  subjectivity,  and  effort  in  performing  procedures  and 
evaluating management’s significant estimates and assumptions in determining the fair value of the reporting unit; and (iii) the audit 
effort involved the use of professionals with specialized skill and knowledge. 

Our audit procedures related to management’s evaluation of goodwill impairment included (i) evaluating the appropriateness of the 
income approach and market approach methods; (ii) testing the underlying data used by the Company in its analysis; and (iii) evaluating 
the reasonableness of significant estimates and assumptions used by management. Evaluating management’s estimates and assumptions 
involved evaluating whether the estimates and assumptions used by management were reasonable considering (i) the current and past 
performance of the reporting unit and (ii) whether these assumptions were consistent with evidence obtained in other areas of the audit. 
We utilized our valuation specialist to assist in evaluating the reasonableness of the Company’s valuation methodology. Furthermore, 
we assessed the appropriateness of the disclosures in the consolidated financial statements. 

Business Combination – Acquisition of Holzworth Instrumentation, Inc. (“Holzworth”) 
In  February  2020,  the  Company  completed  the  acquisition  of  Holzworth for  a purchase  price  of  approximately  $12 million,  which 
includes $2.4 million of contingent consideration, estimated at the acquisition date. The Company accounted for the acquisition under 
the acquisition method of accounting for business combinations. Accordingly, the purchase price was allocated to the assets acquired 
and liabilities assumed based on their respective fair values, including  total intangible assets of $4.3 million. Management, with the 
assistance of an independent valuation expert, estimated the fair value of the intangible assets using the multi-period excess earnings 
method and the relief from royalty methodology, which are both variations of the income approach. Additionally, management, with 
the  assistance  of  an  independent  valuation  expert,  estimated  the  fair  value  of  the  contingent  consideration  using  the  Monte  Carlo 
Simulation model. 

Given  the  fair  value  determination  of  the  intangible  assets  and  contingent  consideration  requires  management  to  make  significant 
estimates and assumptions related to the forecasts of future cash flows and the selection of the discount rate, performing audit procedures 
to evaluate the reasonableness of these estimates and assumptions required a high degree of auditor judgment and an increased extent 
of effort, including the need to involve our valuation specialists. 

Our auditing procedures related to the forecasts of future cash flows and the selection of the discount rate included (i) obtaining an 
understanding of management’s key assumptions in developing the forecast; (ii) assessing the reasonableness of management's forecasts 
of future cash flows by comparing the projections to historical  results; (iii) evaluating whether the estimated future cash flows were 
consistent  with  projections  used  by  the  Company,  as  well  as  evidence  obtained  in  other  areas  of  the  audit;    (iv)  evaluating  the 
reasonableness  of  the  discount  rate  and  (v)  testing  the  mathematical  accuracy  of  the  calculations.  Furthermore,  we  assessed  the 
appropriateness of the disclosures in the consolidated financial statements.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS 
Wireless Telecom Group, Inc. 

NOTE 1 - DESCRIPTION OF COMPANY AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES: 

Organization and Basis of Presentation 

Wireless Telecom Group, Inc., a New Jersey corporation, together with its subsidiaries (“we”, “us”, “our” or the “Company”), 
specializes  in  the  design  and  manufacture  of  advanced  radio  frequency  (“RF”)  and  microwave  devices  which  enable  the 
development, testing and deployment of wireless technology. The Company provides unique, highly customized and configured 
solutions which drive innovation across a wide range of traditional and emerging wireless technologies.   

Our customers include wireless carriers, aerospace companies, defense contractors, military and government agencies, satellite 
communication companies, network equipment manufacturers, tower companies, semiconductor device manufacturers, system 
integrators, neutral host providers and medical device manufacturers.   

Our products include components, modules, instruments, systems and software used across the lifecycle of wireless connectivity 
and  communication  development,  deployment  and  testing.    Our  customers  use  these  products  in  relation  to  commercial 
infrastructure development, the expansion and upgrade of distributed antenna systems, deployment of small cell technology, use 
of medical devices and private long-term evolution (“LTE”) and 5G networks.  In addition, the Company’s products are used in 
the development and testing of satellite communication systems, radar systems, semiconductor devices, automotive electronics 
and avionics.  

The  accompanying consolidated financial statements include the accounts of Wireless Telecom Group, Inc., doing business as 
and operating under the trade name,  Noisecom, and its wholly owned subsidiaries including Boonton Electronics Corporation 
(“Boonton”), Microlab/FXR LLC (“Microlab”), Holzworth Instrumentation, Inc. (“Holzworth”), Wireless Telecommunications 
Ltd. and CommAgility Limited (“CommAgility”).  They have been prepared using accounting principles generally accepted in 
the United States (“U.S. GAAP”).  All intercompany transactions and balances have been eliminated in consolidation.   

In June 2020 the Company completed an internal reorganization and now presents its operations as one reportable segment.  
Prior to June 2020 the Company presented its operations in three reportable segments.  The Company identifies segments in 
accordance with ASC 280 Segment Reporting (“ASC 280”).  As a result of internal reorganizations that occurred over the six to 
nine months prior to June 30, 2020 the Company evaluated its segment reporting.  We determined that the Chief Operating 
Decision Maker (“CODM”) as defined in ASC 280 evaluates operating results and makes decisions on how to allocate resources 
at the consolidated level.  Although the CODM reviews key performance indicators including bookings, shipments and gross 
profit at a product group level, this information by itself is not sufficient enough to make operating decisions.  Rather, operating 
decisions are made based on review of consolidated profitability metrics rather than the individual results of each product group.      

Use of Estimates  

The accompanying financial statements have been prepared in accordance with  U.S. GAAP, which requires management to 
make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets 
and  liabilities  at  the  date  of  the  financial  statements,  as  well  as  the  reported  amounts  of  revenues  and  expenses  during  the 
reporting period. Accordingly, actual results could differ from those estimates. The most significant estimates and assumptions 
include management’s analysis in support of inventory valuation, accounts receivable valuation, valuation of deferred tax assets, 
returns reserves, warranty accruals, goodwill and intangible assets, estimated fair values of stock options and vesting periods of 
performance-based stock options and restricted stock.  

Concentrations of Credit Risk, Purchases and Fair Value 

Financial instruments that potentially subject the Company to concentrations of credit risk consist principally of cash and cash 
equivalents and trade accounts receivable.   

Credit evaluations are performed on customers requiring credit over a certain amount. Credit risk is mitigated to a lesser extent 
through collateral such as letters of credit, bank guarantees or payment terms like cash in advance.  

For  the  twelve  months  ended  December  31,  2020,  no  one  customer  accounted  for  more  than  10%  of  the  Company’s  total 
consolidated revenues.  For the twelve months ended December 31, 201,9 one CommAgility customer accounted for 24.8% of 

27 

 
 
 
 
 
 
 
 
 
 
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS 
Wireless Telecom Group, Inc. 

the Company’s total consolidated revenues. At December 31, 2020, one customer exceeded 10% of consolidated gross accounts 
receivable at 12.7%.  At December 31, 2019 one customer exceeded 10% of consolidated gross accounts receivable at 12.9%.     

For the year ended December 31, 2020, two suppliers exceeded 10% of consolidated inventory purchases at 14% each.  For the 
year ended December 31, 2019, three suppliers comprised or exceeded 10% of consolidated inventory purchases at 18% and 
14% and 10%, respectively.    

Cash and Cash Equivalents 

Cash and cash equivalents represent deposits in banks and highly liquid investments purchased with maturities of three months 
or less at the date of purchase.   

Accounts Receivable and Allowance for Doubtful Accounts 

Trade accounts receivable and contract assets for unbilled receivables are stated at the amount owed by the customer, net of 
allowances for doubtful accounts, returns and rebates.  Estimated allowances for doubtful accounts are reviewed periodically 
taking into account the customer’s recent payment history, the customer’s current financial statements and other information 
regarding the customer’s credit worthiness. Account balances are charged off against the allowance when it is determined the 
receivable will not be recovered. 

Inventories 

Inventories are stated at the lower of cost or net realizable value.  Inventory cost is determined on an average cost basis.  Net 
realizable  value  is  based  upon  an  estimated  average  selling  price  reduced  by  estimated  costs  of  completion,  disposal  and 
transportation.  Reductions in inventory valuation are included in cost of revenues in the accompanying Consolidated Statements 
of  Operations  and  Comprehensive  Income/Loss.    Finished  goods  and  work-in-process  include  material,  labor  and  overhead 
expenses. 

The Company reviews inventory for excess and obsolescence based on best estimates of future demand, product lifecycle status 
and  product  development  plans.    The  Company  uses  historical  information  along  with  these  future  estimates  to  reduce  the 
inventory cost basis. Subsequent changes in facts and circumstances do not result in the restoration or increase in that newly 
established cost basis. 

Inventory carrying value is net of inventory reserves of approximately $1.1 million as of December 31, 2020 and $1.0 million 
as of December 31, 2019. 

Inventories consist of (in thousands): 

Raw materials 

Work-in-process 

Finished goods

prepaid insurance, prepaid maintenance agreements and the short term portion of debt issuance costs.  The income tax receivable 
balance included in prepaid and other current assets was $1.2 million and $1.1 million as of December 31, 2020 and December 
31, 2019, respectively.

Property, Plant and Equipment 

Property, plant and equipment are reflected at cost, less accumulated depreciation. Upon application of acquisition accounting, 
property, plant and equipment are measured at estimated fair value as of the acquisition date to establish a new historical cost 
basis.   

Depreciation and amortization are provided on a straight-line basis over the estimated useful lives of the assets.  The estimated 
useful lives for the property, plant and equipment are: 

Machinery and computer equipment/software 
Furniture and fixtures 

3-8 years  
5-7 years  

Leasehold improvements are amortized over the shorter of the remaining term of the lease or the estimated economic life of the 
improvement.  Repairs and maintenance are charged to operations as incurred; renewals and betterments are capitalized. 

Business Combinations 

The Company uses the acquisition method of accounting for business combinations which requires the tangible and intangible 
assets acquired and liabilities assumed to be recorded at their respective fair market value as of the acquisition date. Goodwill 
represents the excess of the consideration transferred over the fair value of the net assets acquired. The fair values of the assets 
acquired and liabilities assumed are determined based upon the Company’s valuation and involves making significant estimates 
and assumptions based on facts and circumstances that existed as of the acquisition date. The Company uses a measurement 
period following the acquisition date to gather information that existed as of the acquisition date that is needed to determine the 
fair value of the assets acquired and liabilities assumed. The measurement period ends once all information is obtained, but no 
later than one year from the acquisition date. 

Goodwill 

Goodwill  represents  the  excess  of  the  aggregate  purchase  price  over  the  fair  value  of  the  net  assets  acquired  in  a  purchase 
business combination.  Goodwill is evaluated for impairment annually, or more frequently if events occur or circumstances 
change  that  would  indicate  that  goodwill  might  be  impaired,  by  first  performing  a  qualitative  evaluation  of  events  and 
circumstances  impacting  the  reporting  unit  to  determine  the  likelihood  of  goodwill  impairment.    Based  on  that  qualitative 
evaluation, if the Company determines it is more likely than not that the fair value of a reporting unit exceeds its carrying amount, 
no further evaluation is necessary.  Otherwise we perform a quantitative impairment test.   

The Company has three reporting units with goodwill – Holzworth, Microlab and CommAgility.  The Company performed a 
qualitative  assessment  in  the  fourth  quarter  of  2020  of  each  reporting  unit.    The  qualitative  assessment  of  Holzworth  and 
Microlab did not indicate any impairment of goodwill.   As a result of declining  demand of  CommAgility’s signal processing 
hardware  cards  from  a  single  customer  and  the  particularly  high  uncertainty  associated  with  the  ultimate  trajectory  of  the 
pandemic, including the degree to which governments continue to restrict business and personal activities, and the impact that 
uncertainty has on the growth of new software license and services revenue to offset the signal processing hardware sales decline, 
the Company performed a quantitative impairment test of the goodwill of the CommAgility reporting unit.   

For goodwill impairment testing using the quantitative approach, the Company estimates the fair value of the selected reporting 
unit using the income approach and the market approach.  Fair value under the income approach is derived  primarily through 
the use of a discounted cash flow model based on our best estimate of amounts and timing of future revenues and cash flows 
and our most recent business and strategic plans. Fair value under the market approach is derived by applying a multiple to our 
best estimate of future revenue.   The Company applies equal weighting to the income approach and the market approach to 
arrive at an estimated fair value. The estimated fair value  is compared  to the carrying value of the reporting unit, including 
goodwill. If the fair value of the reporting unit exceeds the carrying value, no impairment charge is recorded.  If the carrying 
value of the reporting unit exceeds the fair value an impairment charge is recorded to goodwill in the amount by which carrying 
value  exceeds  fair  value.  Both  the  income  approach  and  market  approach  require  judgmental  assumptions  about  projected 
revenue  growth,  future  operating  margins,  discount  rates  and  terminal  values  over  a  multi-year  period.  There  are  inherent 

29 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
  
 
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS 
Wireless Telecom Group, Inc. 

uncertainties related to these assumptions and management’s judgment in applying them to the analysis of goodwill impairment. 
While the Company believes it has made reasonable estimates and assumptions to calculate the fair value of its reporting units, 
it is possible a material change could occur.  

In the fourth quarter of 2020, the Company recorded a goodwill impairment charge of $4.7 million related to the CommAgility 
reporting unit.  The non-cash impairment charge was due to a number of factors that arose as part of our quantitative assessment, 
including an assessment of our historical results and the significant decline in hardware sales in 2020, the difficulty of predicting 
future customer demand, the uncertainty of future sales of 4G hardware cards, the uncertainty of the growth of 5G software and 
services  revenues  due  to  the  early  stages  of  5G  adoption  for  new  technology  and  expectations  for  5G  deployments,  the 
uncertainty of the continued future impacts of the COVID 19 pandemic on customer spending, and the potential for a more 
prolonged recovery for enterprise spending and longer-term investment.  Despite the asset impairment charge the Company 
believes the markets in which CommAgility operates, specifically LTE and 5G private networks, have long term growth potential 
and the Company is committed to growing the revenue and profitability of the reporting unit.          

Due to the many variables inherent in the estimation of a reporting unit’s fair value and the relative size of our recorded goodwill, 
differences  in  assumptions  may  have  a  material  effect  on  the  results  of  our  impairment  analysis.    After  recording  the  2020 
goodwill impairment charge, the Company’s consolidated goodwill balance as of December 31, 2020 was comprised of $1.4 
million related to the Microlab reporting unit, $6.0 million related to the Holzworth reporting unit and $4.1 million related to 
the CommAgility reporting unit.   

As of December 31, 2019, the Company’s consolidated goodwill balance of $10.1 million was comprised of $1.4 million related 
to the Microlab reporting unit and $8.7 million related to the CommAgility reporting unit.  Management’s qualitative assessment 
performed in the fourth quarter of 2019 did not indicate any impairment of goodwill.  

Intangible and Long-lived Assets 

Intangible assets include  acquired technology,  patents, non-competition agreements, customer relationships and tradenames.  
Intangible assets with finite lives are amortized using the straight-line method over the estimated economic lives of the assets, 
which  range  from  three  to  twelve  years.  Long-lived  assets,  including  intangible  assets  with  finite  lives,  are  reviewed  for 
impairment  whenever  events  or  changes  in  circumstances  indicate  that  the  carrying  amount  of  such  assets  may  not  be 
recoverable. Determination of recoverability is based on an estimate of undiscounted future cash flows resulting from the use of 
the asset and its eventual disposition. Measurement of an impairment loss for long-lived assets that management expects to hold 
and use is based on the estimated fair value of the asset. Long-lived assets to be disposed of are reported at the lower of carrying 
amount or estimated fair value less costs to sell.  The estimated useful lives of intangible and long-lived assets are based on 
many factors including assumptions regarding the effects of obsolescence, demand, competition and other economic factors, 
expectations regarding the future use of the asset, and our historical experience with similar assets. The assumptions used to 
determine  the  estimated  useful  lives  could  change  due  to  numerous  factors  including  product  demand,  market  conditions, 
technological developments, economic conditions and competition.  Intangible assets determined to have indefinite useful lives 
are  not  amortized  but  are  tested  for  impairment  annually  and  more  frequently  if  events  occur  or circumstances  change  that 
indicate an asset may be impaired.   

Fair Value of Financial Instruments 

Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability (an exit price) in an orderly 
transaction  between  market  participants  at  the  reporting  date.  The  accounting  guidance  establishes  a  three-tiered  hierarchy, 
which prioritizes the inputs used in the valuation methodologies in measuring fair value: 

Level 1 - Quoted prices in active markets for identical assets or liabilities. 

Level 2 - Inputs other than Level 1 that are observable, either directly or indirectly, such as 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. 

30 

 
 
 
 
 
  
 
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS 
Wireless Telecom Group, Inc. 

Level 3 - Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the 
assets or liabilities. 

The categorization of a financial instrument within the valuation hierarchy is based on the lowest level of input that is significant 
to the fair value measurement. 

The  carrying  amounts  of  the  Company’s  financial  instruments,  including  cash,  accounts  receivable,  accounts  payable  and 
accrued liabilities, approximate fair value due to their relatively short maturities. The Company’s term loan and revolving credit 
facility bear interest at a variable interest rate plus an applicable margin and, therefore, carrying amount approximates fair value. 
We believe the carrying value of the loan obtained under the Paycheck Protection Program approximates fair value due to the 
expected short term nature of the loan. 

During  the  fourth  quarter  of  2020,  the  Company  recorded  a  goodwill  impairment  charge  of  $4.7  million  related  to  the 
CommAgility reporting unit.  The determination of the impairment charge was based on  the income and market approaches 
which  are  based  on  the  present  value  of future  cash  flows  and  an  estimated  multiple  of  future  revenues,  respectively.    The 
determination of the impairment charge was based on Level 3 valuation inputs.   

Contingent Consideration 

Under the terms of the Holzworth Share Purchase Agreement (as defined in Note 2) the Company is required to pay additional 
purchase price in the form of deferred purchase price payments and an earnout if certain financial targets are achieved for the 
years ending December 31, 2020 and December 31, 2021 (see Note 2).  As of the acquisition date, the Company estimated the 
fair value of the deferred purchase price and earnout remaining to be paid related to the 2020 and 2021 financial targets to be 
$660,000 and $2.4 million, respectively.  The earnout may be paid in cash or common stock at the Company’s option.  The 
Company is required to reassess the fair value of the contingent consideration at each reporting period. 

The significant inputs used in this fair value estimate include estimated gross revenues and Adjusted EBITDA, as defined in the 
Holzworth Share Purchase Agreement, and scenarios for the earnout periods for which probabilities are assigned to each scenario 
to arrive at a single estimated outcome. The estimated outcome is then discounted based on the individual risk analysis of the 
liability.  The contingent consideration liabilities are considered a Level 3 fair value measurement. 

Due to the better than expected financial performance of the Holzworth reporting unit during fiscal 2020, the Company recorded 
an increase to the contingent consideration liabilities in the amount of $1.1 million in the fourth quarter of 2020.  The adjustment 
was recorded as a loss on change in fair value of contingent consideration in the Consolidated Statement of Operations and 
Comprehensive Income/(Loss).   

Foreign Currency Translation 

Assets  and  liabilities  of  non-U.S.  subsidiaries  that  operate  in  a  local  currency  environment,  where  the  local  currency  is  the 
functional currency, are translated from foreign currencies into U.S. dollars at period-end exchange rates while income and 
expenses are translated at the weighted average spot rate for the periods presented. Translation gains or losses related to net 
assets located outside the U.S. are shown as a component of accumulated other comprehensive income in the Consolidated 
Statements of Changes in Shareholders’ Equity.  

Aggregate foreign currency gains and losses, such as those resulting from the settlement of receivables or payables in a currency 
other than the subsidiary’s functional currency, are recorded in the Consolidated Statements of Operations and Comprehensive 
Income/(Loss) (included in other income/expense).  Foreign currency transaction gains were $64,000 in fiscal 2020.  Foreign 
currency transaction losses in in fiscal 2019 were not material.   

Other Comprehensive Income/(Loss) 

Other  comprehensive  income/(loss)  is  recorded  directly  to  a  separate  section  of  shareholders’  equity  in  accumulated  other 
comprehensive income and includes unrealized gains and losses excluded from net income/(loss). These unrealized gains and 
losses consist of changes in foreign currency translation.

Research and Development Costs 

Research  and  development  (R&D)  costs  are  charged  to operations  when  incurred.  R&D  costs  include  salaries  and benefits, 
depreciation expense on equipment used for R&D purposes and third-party material and consulting costs, if clearly related to an 
R&D activity.  Salaries and benefits of engineers working on customer contracts for which the Company is earning services or 
consulting revenues are allocated to costs of revenues.  The amounts charged to operations for R&D costs for the years ended 
December 31, 2020 and 2019 were $6.4 million and $5.9 million, respectively. 

Advertising Costs 

Advertising  expenses  are  charged  to operations  during  the  year  in  which  they  are  incurred  and  aggregated  to $235,000  and 
$91,000 for the years ended December 31, 2020 and 2019, respectively. 

Stock-Based Compensation 

The  Company  follows  the  provisions  of  Accounting  Standards  Codification  (“ASC”)  718,  “Compensation  –  Stock 
Compensation” which requires that compensation expense be recognized, based on the fair value of the  equity awards on the 
date of grant. The fair value of restricted share awards and restricted stock unit awards is determined using the market value of 
our common stock on the date of the grant. The fair value of stock options at the date of grant are estimated using the Black-
Scholes  option  pricing  model.  When  performance-based  stock  options  are  granted,  the  Company  takes  into  consideration 
guidance under ASC 718 and SEC Staff Accounting Bulletin No. 107 (SAB 107) when determining assumptions. The expected 
option life is derived from assumed exercise rates based upon historical exercise patterns and represents the period of time that 
options granted are expected to be outstanding. The expected volatility is based upon historical volatility of our shares using 
daily price observations over an observation period that approximates the expected life of the options. The risk-free rate is based 
on the U.S. Treasury yield curve rate in effect at the time of grant for periods similar to the expected option life.  The Company 
accounts for forfeitures for all equity awards when they occur.   

Management estimates are necessary in determining compensation expense for stock options with performance-based vesting 
criteria. Compensation expense for this type of stock-based award is recognized over the period from the date the performance 
conditions  are  determined  to  be  probable  of  occurring  through  the  implicit  service  period,  which  is  the  date  the  applicable 
conditions are expected to be met. If the performance conditions are not considered probable of being achieved, no expense is 
recognized until such time as the performance conditions are considered probable of being met, if ever. If the award is forfeited 
because the performance condition is not satisfied, previously recognized compensation cost is reversed. Management evaluates 
performance conditions on a quarterly basis. 

Income Taxes 

The  Company  records  deferred  taxes  in  accordance  with  ASC  740,  “Accounting  for  Income  Taxes”.  This  ASC  requires 
recognition of deferred tax assets and liabilities for temporary differences between tax basis of assets and liabilities and  the 
amounts at which they are carried in the financial statements, based upon the enacted rates in effect for the year in which the 
differences  are  expected  to  reverse.  The  Company  establishes  a  valuation  allowance  when  necessary  to  reduce deferred  tax 
assets to the amount expected to be realized. 

The Company periodically assesses the value of its deferred tax asset, a majority of which has been generated by a history of 
net operating losses and determines the necessity for a valuation allowance. The Company evaluates which portion, if any, will 
more likely than not be realized by offsetting future taxable income, taking into consideration any limitations that may exist on 
its use of its net operating loss carry-forwards. 

Under ASC 740, the Company must recognize and disclose uncertain tax positions only if it is  more-likely-than-not the tax 
position will be sustained on examination by the taxing authority, based on the technical merits of the position. The amounts 
recognized in the financial statements attributable to such position, if any, are recorded if there is a greater than 50% likelihood 
of being realized upon the ultimate resolution of the position. Based on the evaluations noted above, the Company has concluded 
that there are no significant uncertain tax positions requiring recognition or disclosure in its consolidated financial statements.

Earnings/(Loss) Per Common Share 

Basic earnings/(loss) per share is calculated by dividing net income/(loss) available to common shareholders by the weighted 
average number of shares of common stock outstanding during the period.  Diluted earnings/(loss) per share is calculated by 
dividing net income/(loss) available to common shareholders by the weighted average number of common shares outstanding 
for the period and, when dilutive, potential shares from stock options using the treasury stock method, the weighted average 
number of unvested restricted shares, the weighted-average number of restricted stock units and the weighted average number 
of warrants to purchase common stock outstanding for the period. Shares from stock options and warrants are included in the 
diluted earnings per share calculation only when options exercise prices are lower than the average market value of the common 
shares for the period presented.  In periods with a net loss, the basic loss per share equals the diluted loss per share as all common 
stock equivalents are excluded from the per share calculation because they are anti-dilutive.   In accordance with ASC 260, 
“Earnings Per Share”, the following table reconciles basic shares outstanding to fully diluted shares outstanding.

The weighted average number of options and warrants to purchase common stock not included in diluted loss per share because 
the effects are anti-dilutive, or the performance condition was not met in 2020 was 3,114,792.  The estimated number of shares 
issuable under the terms of the Holzworth earnout, if the entire earnout was paid in shares of common stock, (see Note 2) at 
December 31, 2020 was 1,559,807. 

The weighted average number of options to purchase common stock not included in diluted loss per share in 2019, because the 
effects are anti-dilutive or the performance condition was not met, was 1,324,548.   

Recent Accounting Pronouncements Adopted in 2020

Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That is a Service Contract.  ASU 2018-15 
aligns  the  requirements  for  capitalizing  implementation  costs  in  cloud  computing  arrangements  with  the  requirements  for 
capitalizing implementation costs incurred to develop or obtain internal-use software.  This pronouncement is effective for the 
Company’s 2020 calendar year, with early adoption permitted.  The adoption of this standard did not have a material impact on 
our consolidated financial statements. 

Recent Accounting Pronouncements Not Yet Adopted 

In June 2016, the FASB issued ASU 2016-13, Financial Instruments – Credit Losses (Topic 326).  ASU 2016-13 changes the 
impairment model for most financial assets and will require the use of an “expected loss” model for instruments measured as 
amortized cost.  This pronouncement is effective for small reporting companies for fiscal years, and for interim periods within 
those fiscal years, beginning after December 15, 2022.  The Company plans to adopt the standard effective January 1, 2023.  We 
do not expect the adoption of this standard to have a material impact on our consolidated financial statements.   

In December 2019, the FASB issued ASU 2019-12, Income Taxes (Topic 740) Simplifying the Accounting for Income Taxes.  
The amendments simplify the accounting for income taxes by removing certain exceptions to the general principles of Topic 
740 and improve consistent application by clarifying and amending existing guidance. The new standard is effective for fiscal 
years, and interim periods within those fiscal years, beginning after December 15, 2020. Early adoption is permitted, with the 
amendments to be applied on a retrospective, modified retrospective or prospective basis, depending on the specific amendment.  
We do not expect the adoption of this standard to have a material impact on our consolidated financial statements.

NOTE 2 – Acquisition of Holzworth 

On  November  13,  2019  the  Company  entered  into  a  Share  Purchase  Agreement  with  Holzworth  Instrumentation  Inc. 
(“Holzworth”), its founders and shareholders (collectively, the “Sellers”), as amended by a First Amendment to Share Purchase 
Agreement,  dated  January  31,  2020  and  a  Second  Amendment  to  Share  Purchase  Agreement  dated  February  19,  2021 
(collectively,  the  “Share  Purchase  Agreement”).    On  February  7,  2020,  the  Company  completed  the  acquisition  (the 
“Acquisition”)  of  all  of  the  outstanding  shares of  Holzworth,  from  the  Sellers.  Holzworth  instruments  which  include signal 
generators  and  phase  noise  analyzers  are  used  by  government  labs,  aerospace  and  defense  companies,  the  semiconductor 
industry,  and  network  equipment  providers,  among  others,  in  research  and  automated  test  environments.    Holzworth  is  a 
complimentary business for our Boonton and Noisecom brands with a common customer base and channel partners.  For the 
twelve months ended December 31, 2020, net revenues of $8.8 million, and operating income of $1.4 million, respectively, was 
included in the Consolidated Statements of Operations and Comprehensive Income/(Loss) related to the Holzworth business, 
representing the results from the date of acquisition.    For the twelve months ended December 31, 2020, the Company recorded 
$243,000 of transaction expenses related to the Acquisition and these expenses were recognized in general and administrative 
expenses in the Consolidated Statements of Operations and Comprehensive Income/(Loss).     

The aggregate purchase price for the Acquisition is a maximum of $17.0 million, consisting of payments in cash and stock,  a 
working  capital  adjustment,  and  contingent  consideration  in  the  form  of  deferred  purchase  price  payments  and  an  earnout.  
Additionally, the parties made a 338(h)(10) election to treat the Acquisition as a purchase and sale of assets, and the Company 
has agreed to pay any incremental taxes of Sellers resulting from that election.   

At closing, a portion of the purchase price was paid to the Sellers through the issuance of 347,319 shares of the Company’s 
common stock, valued at approximately $500,000 based upon a 90-day volume weighted average price for shares of stock of 
the Company.  The shares issued to the Sellers are subject to Lock-up and Voting Agreements.   

During 2020, the Company paid $8.3 million in net cash to the Sellers consisting of $7.2 million in cash at close, $600,000 in 
indemnification  holdback  payments  and  $750,000  in  deferred  purchase  price  reduced  by  $292,000  of  a  working  capital 
adjustment that was owed to the Company by the Sellers.  The final indemnification holdback payment of $200,000 is due on 
March 31, 2021.     

The Sellers earned a second deferred purchase price payment of $750,000 by way of exceeding $1.25  million in EBITDA (as 
defined in the Share Purchase Agreement) for the twelve months ended December 31, 2020.  Additionally,  the Sellers earned 
$3.4 million in additional purchase price in the form of an earnout  (“Year 1 Earnout”) which was also based on Holzworth’s 
EBITDA for the twelve months ended December 31, 2020.   

On  February  19,  2021,  the  Company  entered  into  the  Second  Amendment  to  Share  Purchase  Agreement  (the  “Second 
Amendment”) with Holzworth.  The Second Amendment, among other things, converted the second deferred purchase price of 
$750,000 into unsecured seller notes with interest at an annual rate of 6.5% starting from April 1, 2021 until final payment. The 
payment date has been changed from March 31, 2021 to three equal installments of $250,000, plus accrued interest, due on July 
1, 2021, October 1, 2021 and January 1, 2022. 

Additionally, the parties amended the payment dates of the earnout consideration. The payment date of the first earnout payment 
based on the financial results of the calendar year ended 2020 (“Year 1 Earnout”) has been amended from March 31, 2021 to (i) 
six (6) equal quarterly installments of 10% of the Year 1 Earnout payable on the last business day of each calendar quarter 
between June 30, 2021 and September 30, 2022 and (ii) one (1) installment payment equal to 40% of the Year 1 Earnout on 

34 

 
 
 
 
 
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS 
Wireless Telecom Group, Inc. 

December 31, 2022. The Year 1 Earnout is payable in cash or shares of the Company’s common stock based on the 90 trading 
day volume weighted average price immediately preceding final determination of the Year 1 Earnout or $2.19 per share.  The 
estimated payment for the Year 1 Earnout is $3.4 million which is recorded in accrued expenses and other current liabilities in 
the Consolidated Balance Sheet as of December 31, 2020.   

The Company may also be required to pay additional amounts in cash and stock as earnout consideration based on Holzworth’s 
EBITDA for the fiscal year ending December 31, 2021 (“Year 2 Earnout”).  The Year 2 Earnout will be equal to two times the 
amount, if any, by which Holzworth’s EBITDA for fiscal year December 31, 2021 exceeds Holzworth’s EBITDA for fiscal year 
2020.  Pursuant to the Second Amendment to the Share Purchase Agreement the Year 2 Earnout is payable in 4 equal quarterly 
installments payable on the last business day of each calendar quarter between March 31, 2022 and December 31, 2022.  The 
aggregate earnout payments cannot exceed $7.0 million.     

Pursuant to the Share Purchase Agreement the Company entered into a lock-up and voting agreement (the “Lock-up and Voting 
Agreement”) with each of the Sellers. Pursuant to the Lock-up and Voting Agreement, each Seller agrees to restrict the sale, 
assignment, transfer, encumbrance or other disposition of its portion of the Stock Consideration (the “Lock-up Shares”).  For a 
period commencing on the closing date of the Acquisition (the “Effective Date”) and ending on the date which is 36 calendar 
months following the Effective Date, each Seller agreed that, without the prior written consent by the Company, such Seller 
would not sell, assign, transfer, encumber or otherwise dispose of the Lock-up Shares or enter into any swap, option or short 
sale, among other transactions.   Upon the prior written consent of the Company, a Seller may transfer Lock-up Shares as a bona 
fide gift, by will or intestacy or to a family member or trust for the benefit of the Seller or a family member; provided that any 
recipient of the Lock-up Shares sign and deliver to the Company a lock-up and voting agreement substantially in the form of the 
Lock-up and Voting Agreement. The Lock-up Shares cease to be locked up in the event of a Change of Control of the Company 
(as defined in the Lock-up and Voting Agreement).  In the Second Amendment, the parties also amended the provisions with 
respect to restrictions on transfer to adjust for the change in timing of earnout payments, as described above.   

In addition, each Seller, subject to certain limitations, agreed, among other things, to appear at each meeting of the shareholders 
of the Company and vote all of such Seller’s Lock-up Shares (a) in favor or against any proposal presented to the shareholders 
in the same manner that the Company’s Board of Directors (the “Board”) recommends shareholders vote on such proposal and 
(b)  in  favor  of  any  proposal  presented  to  the  shareholders  with  respect  to  an  action  of  the  Company  which  the  Board  has 
approved, but as to which the Board has not made any recommendation, including in favor of any proposal to adjourn or postpone 
any meeting of the Company’s shareholders if such adjournment or postponement is conducted in accordance with the terms of 
the Lock-up and Voting Agreement. 

To the extent any shares of Company common stock are issued in payment of any Earnout Consideration (as defined in the 
Share Purchase Agreement) in accordance with the terms of the Share Purchase Agreement, such shares shall be subject to all 
applicable transfer restrictions, voting and other provisions set forth in the Lock-up and Voting Agreement, with the Effective 
Date with respect to such shares being the date such shares are issued; provided that, to the extent the portion of the first $1.5 
million of Earnout Consideration that is paid in cash represents less than 30%  of such Earnout Consideration, the portion of 
shares of Company common stock issued as Earnout Consideration constituting the difference between the cash percentage paid 
and 30% of the first $1.5 million of Earnout Consideration shall not be considered Lock-Up Shares.  In addition, in the Second 
Amendment, the parties added a requirement that any earned but unpaid earnout consideration will be accelerated in the event 
the Company desires to enter into a material asset or equity acquisition in the future. 

The  acquisition  has  been  accounted  for  under  the  acquisition  method  of  accounting  in  accordance  with  ASC  805,  Business 
Combinations.  Accounting  for  acquisitions  requires  us  to  recognize  separately  from  goodwill  the  assets  acquired  and  the 
liabilities  assumed  at  their  acquisition  date  fair  values.  Goodwill  as  of  the  acquisition  date  is  measured  as  the  excess  of 
consideration transferred over the net of the acquisition date fair values of the assets acquired and the liabilities assumed. While 
we use our best estimates and assumptions to accurately value assets acquired and liabilities assumed at the acquisition date our 
estimates are inherently uncertain and subject to refinement.  Various valuation techniques were used to estimate the fair value 
of assets acquired and the liabilities assumed which use significant unobservable inputs, or Level 3 inputs as defined by the fair 
value hierarchy.  Using these valuation approaches requires the Company to make significant estimates and assumptions.

As of September 30, 2020, the valuation studies necessary to determine the fair market value of the assets acquired and liabilities 
assumed were completed, including the validation of the underlying cash flows used to determine the fair value of the identified 
intangible  assets  and  contingent  consideration.    The  following  amounts  represent  the  determination  of  the  fair  value  of

In  connection  with  the  Holzworth  acquisition,  on  February  7,  2020,  the  Company,  as  borrower,  and  its  subsidiaries,  as 
guarantors, and Muzinich BDC, Inc., as lender (“Muzinich”), entered into a Term Loan Facility, which provides for a term loan 
in the principal amount of $8.4 million (the “Initial Term Loan”).   All proceeds of the Initial Term Loan were used to fund the 
cash portion of the purchase price for the Holzworth acquisition.  Principal payments on the Initial Term Loan are $21,000 per 
quarter with a balloon payment at maturity which is February 7, 2025. The Term Loan Facility includes an upfront fee of 2.50% 
of the aggregate principal amount of the Initial Term Loan.  In connection with the Term Loan Facility, the Company incurred 
costs of $1.0 million, including the aforementioned 2.5% upfront fee to Muzinich, which were recorded as a reduction of the 
carrying amount of the debt and are being amortized over the term of the loan.     

On  May  4,  2020,  the  Company  entered  into  the  First  Amendment  to  the  Term  Loan  Facility  which,  among  other  things, 
amended the definition of “Indebtedness” to include the PPP loan as long as the proceeds are used for allowable purposes under 
the  CARES  Act,  the  receipt  of  the  loan  does  not  violate  the  Credit  Facility  and  the  Company  submits  an  application  for 
forgiveness and substantially all of the loan is forgiven. 

On February 25, 2021, the Company and its subsidiaries entered into the Second Amendment to  the Credit Agreement and 
Limited Waiver (“Amendment 2”) with Muzinich, in which Muzinich agreed to waive the Company’s obligation to comply 
with the consolidated leverage ratio and fixed charge coverage ratio financial covenants in the Term Loan Facility for the fiscal

quarter ending December 31, 2020. We were not in compliance with such covenants primarily as a result of the impact the 
COVID-19 pandemic had on our consolidated financial results.  Amendment 2, among other things, amends the definition of 
consolidated  EBITDA  to  include  certain  cash  tax  benefits related  to our  UK  tax  jurisdiction  and  reduced  our  consolidated 
leverage ratio for the twelve month periods ended September 30, 2021 from 3.00 to 2.75, December 31, 2021 from 2.75 to 
2.25, March 31, 2022 from 2.50 to 2.00 and June 30, 2022 from 2.25 to 2.00. Additionally, the interest rate margin was increased 
from  7.25%  to  9.25%  effective  January  1,  2021  and  will  step  down  to  8.50%  and  7.25%  upon  the  Company  achieving 
consolidated  EBITDA  on  a  trailing  twelve-month  basis  of  $4.0  million  and  $6.3  million,  respectively.  Muzinich  and  the 
Company also agreed on an excess cash flow payment of $428,000 and Muzinich provided consent for the Company to change 
the deferred purchase price payments to and enter into notes with the Holzworth sellers in the amount of $750,000, as described 
below. 

The Company may prepay the Initial Term Loan at any time.  Prepayments made prior to (a) February 7, 2022 are subject to a 
prepayment  premium  in  the  amount  of  2.0%  of  the  prepaid  principal  amount  and  (b)  February  7,  2023  are  subject  to  a 
prepayment premium in the amount of 1.0% of the prepaid principal amount.  The Company is required to make prepayments 
of the Initial Term Loan with the proceeds of certain asset dispositions, insurance recoveries and extraordinary receipts, subject 
to specified reinvestment rights.  The Company is also required to make prepayments of the Initial Term Loan upon the issuance 
of  certain  indebtedness  and  to  make  an  annual  prepayment  based  upon  the  Company’s  excess  cash  flow.    Mandatory 
prepayments  with  asset  sale,  insurance  or  condemnation  proceeds  and  excess  cash  flow  may  be  made  without  penalty.  
Mandatory prepayments with the proceeds of indebtedness are subject to the same prepayment penalties as are applicable to 
voluntary prepayments.  

The Term Loan Facility provides for an additional $11.6 million term loan (the “Second Term Loan”) to be used for a second 
unannounced acquisition opportunity (the “Additional Acquisition”). There can be no assurance that the Additional Acquisition 
will be completed.  In the event the Additional Acquisition is completed, the Second Term Loan will be made available to the 
Company on the same terms and conditions as the Initial Term Loan, including interest rate, amortization schedule and financial 
covenants, subject to the payment of an additional upfront fee and satisfaction of customary conditions to funding. 

The Term Loan Facility is secured by liens on substantially all of the Company’s and its subsidiaries’ assets including a pledge 
of the equity interests in the Company’s subsidiaries. The Term Loan Facility contains customary affirmative and negative 
covenants  for  a  transaction  of  this  type,  including,  among others,  the  provision of  annual,  quarterly  and monthly  financial 
statements and compliance certificates, maintenance of property, insurance, compliance with laws and environmental matters, 
restrictions on incurrence of indebtedness, granting of liens, making investments and acquisitions, paying dividends, entering 
into affiliate transactions and asset sales. In addition, the Company must maintain certain financial covenants typical for this 
type of arrangement, including a consolidated leverage ratio, a consolidated fixed charge coverage ratio and minimum liquidity 
of its foreign subsidiaries.  The consolidated leverage ratio, as described above, is defined as the ratio of total consolidated 
indebtedness, as defined, to consolidated EBITDA, as defined.  Prior to Amendment 2, the required leverage ratio started at 
4.75 to 1.0 for the twelve month periods ended March 31, 2020 and June 30, 2020, and decreased in various increments to 4.0 
to 1.0 for the twelve months ended September 30, 2020, 3.75 to 1.0 for the twelve months ended December 31, 2020, 2.75 to 
1.0  for  the  twelve  months  ended  December  31,  2021  and 2.0  to  1.0  for  the  twelve  months  ended  December  31, 2022  and 
thereafter.  The consolidated fixed charge coverage ratio is the ratio of consolidated EBITDA, as defined, less consolidated 
capital  expenditures  and  cash  income  taxes  paid  to  consolidated  fixed  charges,  as  defined,  calculated  on  a  twelve-month 
basis.  The consolidated fixed charge coverage ratio for the twelve month periods ended March 31, 2020, June 30, 2020 and 
September 30, 2020 must be 1.35 to 1 and increases in various increments on a quarterly basis to 1.5 to 1.0 for the twelve 
month  period  ended  December  31,  2020  and  2021,  and  to  1.75  to  1.0  for  the  12  months  ending  December  31,  2022  and 
thereafter.  Lastly, the Company must maintain minimum liquidity, defined as cash and availability under the UK borrowing 
base,  as  defined,  of  $1.0  million  over  any  trailing  four-week  period  until  such  time  as  the  foreign  subsidiary  has  positive 
EBITDA, as defined, for three consecutive quarters and the Holzworth deferred purchase price has been paid in full.  The Term 
Loan Facility also provides for a number of events of default, including, among others, nonpayment, bankruptcy, inaccuracy 
of representations and warranties, breach of covenant, change in control, entry of final judgement or order, breach of material 
contracts, and as long as the Company’s consolidated leverage ratio is greater than 1.0 to 1.0 (as calculated in accordance with 
the terms of the Term Loan Facility), the cessation of service of any two of Tim Whelan, Michael Kandell or Daniel Monopoli 
as  Chief  Executive  Officer,  Chief  Financial  Officer  or  Chief  Technology  Officer,  respectively,  of  the  Borrower  without  a 
satisfactory replacement within 60 days. Any exercise of remedies by Muzinich is subject to compliance with the intercreditor 
agreement entered into at the closing of the Term Loan Facility among the Company, Muzinich and Bank of America, N.A., 
as lender under the Credit Facility referenced below.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS 
Wireless Telecom Group, Inc. 

The Company entered into a Credit Facility with Bank of America, N.A. (the “Lender”) on February 16, 2017 (the "Credit 
Facility"), which provided for a term loan in the aggregate principal amount of $760,000 (the "Term Loan") and an asset based 
revolving loan (the “Revolver”), which is subject to a Borrowing Base Calculation (as defined in the Credit Facility) of up to 
a maximum availability of $9.0 million (“Revolver Commitment Amount”).  The borrowing base is calculated as a percentage 
of eligible accounts receivable and inventory, as defined, subject to certain caps and limits.  The borrowing base is calculated 
on a monthly basis and interest is calculated at LIBOR plus a margin.  The proceeds of the Term Loan and Revolver were used 
to finance the acquisition of CommAgility in 2017.  

In  connection  with  the  Holzworth  acquisition,  on  February  7,  2020,  the  Company  and  certain  of  its  subsidiaries  (the 
“Borrowers”), and Bank of America, N.A. entered into Amendment No. 5 (“Amendment 5”) to the Credit Facility.  By entering 
into  Amendment  5,  Holzworth,  together  with  CommAgility  Limited,  became  borrowers  under  the  Credit  Facility.    The 
obligations of the Borrowers under the Credit Facility are guaranteed by Wireless Telecom Group, Ltd.  CommAgility Limited 
and Wireless Telecom Group, Ltd. are both wholly owned subsidiaries of the Company.   

Amendment  5  (a)  effected  certain  modifications  to  the  Credit  Facility  to  accommodate  the  Holzworth  acquisition,  the 
Company’s incurrence of the Initial Term Loan and the granting of the related liens and security interests, (b) subject to the 
satisfaction  of  certain  conditions  precedent,  made  available  to  CommAgility  an  asset  based  revolving  loan,  subject  to  a 
borrowing base calculation applicable to CommAgility’s assets, of up to a maximum availability of $5.0 million (the “UK 
Revolver Commitment”), (c) reduced the interest rate margin applicable to revolving loans made under the Credit Facility from 
a range of 2.75% to 3.25% to a range of 2.00% to 2.50%, based on the Borrowers’ Fixed Charge Coverage Ratio (as defined 
in the Credit Facility) of the most recently completed fiscal quarter, (d) extended the Revolver Termination Date to March 31, 
2023 and (e) conditioned the Borrowers’ ability to make certain debt payments under the Term Loan Facility (described above) 
upon compliance with a liquidity test.  In all other material respects, the Credit Facility remains unchanged.   

Effectiveness of Amendment 5 was conditioned upon, among other things, the prepayment of the remaining principal balance 
($304,000) of the $760,000 term loan made available under the Credit Facility and the payment of a closing fee in the amount 
of $25,000.  The Borrowers satisfied all such conditions on February 7, 2020.  In connection with the Amendment the Company 
incurred costs of $270,000 which are capitalized as other current and non-current assets in the Consolidated Balance Sheets 
and are being amortized over the term of the revolver.     

On May 4, 2020, the Company, its subsidiaries and Bank  of America  entered into Amendment No. 6 which, among other 
things, amended the definition of “Debt” to include the PPP loan as long as the proceeds are used for allowable purposes under 
the CARES Act and the Company promptly submits an application for forgiveness and substantially all of the loan is forgiven. 

On February 25, 2021, the Company, its subsidiaries and Bank of America entered into Amendment No. 7 which revised the 
Credit Facility to accommodate the changes to the deferred purchase price payments to and notes with the Holzworth sellers 
as described above and provided Bank of America’s consent to the Company entering into the Muzinich Second Amendment, 
as described above.  

As of December 31, 2020, the interest rate on the Term Loan Facility was 8.25% and the interest rate on the Revolver was 
2.15%.  The Company had zero drawn on the asset based revolver as of December 31, 2020.  

On  May  4,  2020,  the  Company  received $2.0 million  pursuant  to  a  loan  from  Bank  of America  N.A.  under  the  Paycheck 
Protection Program (“PPP”) of the 2020 Coronavirus Aid, Relief and Economic Security Act (the “CARES Act”) administered 
by the Small Business Association (“SBA”).  The loan has an interest rate of 1% and a term of 24 months. A repayment schedule 
has not yet been provided by Bank of America.  Accordingly, the full amount of the term loan has been shown as due in May 
2022.  Funds from the loan may only be used for certain purposes, including payroll, benefits, rent and utilities. The CARES 
Act and the PPP provide a mechanism for forgiveness of up to the full amount of the loan upon application to the SBA for 
forgiveness by the Company.  The loan is evidenced by a promissory note, which contains customary events of default relating 
to, among other things, payment defaults and breaches of representations and warranties. The Company may prepay the loan at 
any time prior to maturity with no prepayment penalties.  As of December 31, 2020, the Company has applied for forgiveness 
of the loan, however, has elected to account for the loan in accordance with Accounting Standard Codification 470 Debt until 
such time that forgiveness is approved by the SBA.  The Company can provide no assurance that the loan will be forgiven in 
whole or in part.

Issuance of Stock Warrants 

Pursuant to the Term Loan Facility, the Company issued a Warrant, dated February 7, 2020  (the “Warrant”), to Muzinich. 
Under the Warrant, Muzinich has the right to purchase 266,167 shares of common stock of the Company at an exercise price 
of $1.3923 per share (an aggregate value of approximately $370,588), based on a 90-day volume weighted average price for 
shares of stock of the Company (the “Warrant Stock”). The Warrant is exercisable for an indefinite period from the date of the 
Warrant and may be exercised on a cashless basis. The number of shares of common stock deliverable upon exercise of the 
Warrant is subject to adjustment for subdivision or consolidation of shares and other standard dilutive events.   Additionally, 
the exercise price may be adjusted based on a formula in the event of a common stock offering by the Company at an offering 
price  below  fair  market  value,  as  defined,  and  below  exercise  price.    In  connection  with  the  issuance  of  the Warrant,  the 
Company granted Muzinich one demand registration right and piggyback registration rights with respect to the Warrant Stock, 
subject to certain exceptions.   

If the Additional Acquisition (as defined in Term Loan Facility above) is consummated, the Company has agreed to issue to 
Muzinich at the closing of the Additional Acquisition an additional Warrant for the right to purchase 367,564 shares of common 
stock of the Company at an exercise price of $1.3923 per share (an aggregate value of approximately $511,765), based upon a 
90-day volume weighted average price for shares of stock of the Company as of February 7, 2020 (the “Additional Warrant”).  
The Additional Warrant will contain the same terms and conditions as the Warrant, except that Muzinich will have only one 
demand registration right, subject to certain exceptions, with respect to shares of common stock of the Company issued under 
the Warrant and the Additional Warrant. 

The stock warrants issued to Muzinich are classified as equity.  The fair value of the warrants, as calculated using the Black 
Scholes model as of the issuance date, was approximately $150,000 and was recorded as a reduction to the carrying value of 
the debt.  The significant inputs included in the Black Scholes calculation were a risk free rate of 1.41%, volatility of 48.7% 
and the stock price on date of grant of $1.34.   

NOTE 4 - LEASES 

The Company’s lease agreements consist of building leases for its operating locations and office equipment leases for printers 
and copiers with lease terms that range from  less than 12 months to 8 years.  At inception, the Company determines if an 
arrangement  contains  a  lease  and  whether  that  lease  meets  the  classification  criteria  of  a  finance  or  operating  lease.    The 
Company’s leases for office equipment such as printers and copiers contain lease and non-lease components (i.e. maintenance).  
The Company accounts for lease and non-lease components of office equipment as a single lease component.   

All of the Company’s leases are operating leases and are presented as right of use lease asset, short term lease liability and long 
term lease liability on the Consolidated Balance Sheets as of December 31, 2020 and 2019.  These assets and liabilities are 
recognized at the commencement date based on the present value of remaining lease payments over the lease term using the 
Company’s incremental borrowing rate.  Short-term leases, which have an initial term of 12 months or less, are not recorded 
on the balance sheet.   

Lease expense is recognized on a straight-line basis over the lease term and is included in cost of revenues and general and 
administrative expenses on the Consolidated Statement of Operations and Comprehensive Income/(Loss).   

An initial right-of-use asset of $1.9 million was recognized as a non-cash asset addition with the adoption of the new lease 
accounting standard on January 1, 2019.  With our acquisition of Holzworth on February 7, 2020, we acquired a right-of-use 
asset of $789,000.  There have been no other right-of-use assets recognized since the date of adoption of the new lease standard.    
Cash paid for amounts included in the present value of operating lease liabilities was $648,000 and $508,000 during the twelve 
months ended December 31, 2020 and 2019, respectively, and is included in operating cash flows.       

Operating  lease  costs  were  $1.0  million  and  $892,000  during  the  twelve  months  ended  December  31,  2020  and  2019, 
respectively.   

The following table presents information about the amount and timing of cash flows arising from the Company’s operating 
leases as of December 31, 2020.

NOTE 5 – REVENUE 

Revenue is recognized upon transfer of control of promised products or services to customers in an amount that reflects the 
consideration  to  which  the  Company  expects  to  be  entitled  in  exchange  for  promised  goods  or  services.  The  Company’s 
performance  obligations  are  satisfied  either  over  time  or  at  a  point  in  time.  Revenue  from  performance  obligations  that 
transferred at a point in time accounted for approximately 99% of the Company’s total revenue for the twelve months ended 
December 31, 2020 and 2019.  

Nature of Products and Services 

Hardware 

The Company generally has one performance obligation in its arrangements involving the sales of radio frequency solutions, 
digital  signal  processing  hardware,  power  meters,  analyzers,  noise/signal  generators,  phase  noise  analyzers  and  other 
components.  When the terms of a contract include the transfer of multiple products, each distinct product is identified as a 
separate  performance  obligation.    Generally,  satisfaction  occurs  when  control  of  the  promised  goods  is  transferred  to  the 
customer in exchange for consideration in an amount for which we expect to be entitled.  Generally, control is transferred when 
legal title of the asset moves from the Company to the customer. We sell our products to a customer based on a purchase order, 
and the shipping terms per each individual order are primarily used to satisfy the single performance obligation. However, in 
order to determine control has transferred to the customer, the Company also considers: 

(cid:120)  when the Company has a present right to payment for the asset 
(cid:120)  when the Company has transferred physical possession of the asset to the customer  
(cid:120)  when the customer has the significant risks and rewards of ownership of the asset  
(cid:120)  when the customer has accepted the asset

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS 
Wireless Telecom Group, Inc. 

Software 

Arrangements involving licenses of software in the CommAgility brand may involve multiple performance obligations, most 
notably subsequent releases of the software.  The Company has concluded that each software release in a multiple deliverable 
arrangement involving CommAgility software licenses is a distinct performance obligation and, accordingly, transaction price 
is allocated to each release when the customer obtains control of the software. 

Performance obligations that are not distinct at contract inception are combined. Specifically, with the Company’s sales of 
software, contracts that include customization may result in the combination of the customization services with the license as 
one distinct performance obligation and recognized over time.  The duration of these performance obligations are typically one 
year or less.   

Services 

Arrangements involving calibration and repair services of the Company’s products are generally considered a single 
performance obligation and are recognized as the services are rendered.    

Shipping and Handling 

Shipping and handling activities performed after the customer obtains control are accounted for as fulfillment activities and 
recognized as cost of revenues.   

Significant Judgments 

For the Company’s more complex software and services arrangements significant judgment is required in determining whether 
licenses and services are distinct performance obligations that should be accounted for separately, or, are not distinct and thus 
accounted for together.  Further, in cases where we determine that performance obligations should be accounted for separately, 
judgment is required to determine the standalone selling price for each distinct performance obligation.   

Certain  of  the  Company  shipments  include  a  limited return  right.   In  accordance  with Topic  606  the  Company recognizes 
revenue net of expected returns.   

Contract Balances  

The timing of revenue recognition may differ from the timing of invoicing to customers and these timing differences result in 
contract assets (unbilled revenue) or contract liabilities (deferred revenue) on the Company’s Consolidated Balance Sheet.  The 
Company  records  a  contract  asset  when  revenue  is  recognized  prior  to  invoicing,  or  deferred  revenue  when  revenue  is 
recognized  subsequent  to  invoicing.    Unbilled  revenue  is  $260,000  and  $147,000  as  of  December  31,  2020  and  2019, 
respectively,  and  recorded  in  prepaid  expenses  and  other  current  assets.    Deferred  revenue  is  $924,000  and  $42,000  as  of 
December 31, 2020 and 2019, respectively.  The increase in deferred revenue from the prior year is primarily due to billings in 
advance of revenue recognition for certain CommAgility projects involving multiple performance obligations.     

Disaggregated Revenue 

We disaggregate our revenue from contracts with customers by product family and geographic location as we believe it best 
depicts how the nature, timing and uncertainty of our revenue and cash flows are affected by economic factors.  See details in 
the tables below (in thousands).

Net revenues are attributable to a geographic area based on the destination of the product shipment.   

The majority of shipments in the Americas are to customers located within the United States. For the years ended December 
31, 2020 and 2019, sales in the United States amounted to $30.6 million and $30.0 million, respectively.   

For the year ended December 31, 2020 shipments to the EMEA region were largely concentrated in the UK, Russia and France.  
Shipments to the UK, Russia and France in 2020 amounted to $1.7 million, $897,000 and $859,000, respectively.  For the year 
ended December 31, 2019 shipments to the EMEA region were largely concentrated in the UK, Germany and Italy.  Shipments 
to the UK, Germany and Italy in 2019 amounted $12.7 million, $737,000 and $506,000, respectively.  

The largest concentration of shipments in the APAC region is to China.  For the  years ended December 31, 2020 and 2019, 
shipments to China amounted to $2.0 million and $1.3 million, of all shipments to the APAC region, respectively. There were 
no other shipments significantly concentrated in one country in the APAC region.

NOTE 10 - ACCOUNTING FOR STOCK BASED COMPENSATION 

The Company follows the provisions of ASC 718. The Company’s results for the years ended December 31, 2020 and December 
31, 2019 include stock based compensation expense totaling $474,000 and $584,000, respectively.  Such amounts have been 
included in the Consolidated Statement of Operations and Comprehensive Income/(Loss) within operating expenses.    

Incentive Compensation Plan 

In 2012, the Company’s Board of Directors and shareholders approved the 2012 Incentive Compensation Plan (the “Initial 2012 
Plan”),  which  provides  for  the  grant  of  equity,  including  restricted  stock  awards,  restricted  stock  units,  non-qualified  stock 
options and incentive stock options in compliance with the Internal Revenue Code of 1986, as amended, to employees, officers, 
directors, consultants and advisors of the Company who are expected to contribute to the Company's future growth and success. 
When originally approved, the Initial 2012 Plan provided for the grant of awards relating to 2 million shares of common stock, 
plus those shares subject to awards previously issued under the Company’s 2000 Stock Option Plan that expire, are canceled or 
are terminated after adoption of the Initial 2012 Plan without having been exercised in full and would have been available for 
subsequent grants under the 2000 Stock Option Plan. In June 2014, the Company’s shareholders approved the Amended and 
Restated 2012 Incentive Compensation Plan (the “2012 Plan”) allowing for an additional 1.6 million shares of the Company’s 
common stock to be available for future grants under the 2012 Plan. The 2012 Plan provides that if awards are forfeited, expire 
or otherwise terminate without issuance of the shares underlying the awards, or if the award does not result in issuance of all or 
part of the shares underlying the award, the unissued shares are again available for awards under the 2012 Plan.  As a result of 
certain  award  forfeitures  and cancellations,  as  of  December  31,  2020,  there  are  approximately  227,000  shares  available  for 
issuance under the 2012 Plan. 

All service-based (time vesting) options granted have ten-year terms from the date of grant and typically vest annually and 
become fully exercisable after a maximum of five years. However, vesting conditions are determined on a grant by grant basis.  
Performance-based options granted have ten-year terms and vest and become fully exercisable when determinable performance 
targets are achieved. Performance targets are approved by the Company’s compensation committee of the Board of Directors.

Under the 2012 Plan, options may be granted to purchase shares of the Company’s common stock exercisable only at prices 
equal to or above the fair market value on the date of the grant.  

The  following  summarizes  the  components  of  stock-based  compensation  expense  for  the  years  ending  December  31  (in

As of December 31, 2020, $423,000 of unrecognized compensation costs related to unvested stock options is expected to be 
recognized  over  a  remaining  weighted  average  period  of  4.9  years,  $93,000  of  unrecognized  compensation  costs  related  to 
unvested  restricted shares is expected to be recognized over a remaining weighted average period of 2.3 years and $81,000 of 
unrecognized compensation costs related to unvested restricted stock units is expected to be recognized over 6 months.   

During the twelve months ended December 31, 2020 the Company reversed $6,000 and $16,000 in share based compensation 
expense related to 6,250 unvested stock options and 16,667 unvested restricted shares, respectively, which were forfeited as a 
result of an employee exiting the company.

Restricted Stock Units: 

In fiscal 2020 and fiscal 2019 the Company granted Restricted Stock Units (“RSU”) to each of our board members.  Each RSU 
represents the Company’s obligation to issue one share of the Company’s common stock subject to the RSU award agreement 
and 2012 Plan.  The RSUs vest on the day before the first anniversary of the grant date or, if earlier, the effective date of a 
separation of service due to death or disability, provided the board member has rendered continuous service to the Company as 
a member of the board of directors from grant date to vesting date.  Once vested, the RSU will be settled by delivery of shares 
to the board member no later than 30 days following:  1) the third anniversary of the grant date, 2) separation from service 
following, or coincident with, a vesting date, or 3) a change in control.

On August 4, 2020 the Company granted 150,000 performance-based stock options to our Chief Revenue Officer under the 
2012 Plan.     

On April 7, 2020 the Company granted 970,000 performance-based stock options to various employees under the 2012 Plan.   

The performance options granted on both August 4 and April 7, 2020 vest when the Company achieves consolidated revenue 
targets as outlined in the schedule below: 

Consolidated annualized gross revenues $55.0 million – 25% vesting 

Consolidated annualized gross revenues $61.5 million – 50% vesting 

Consolidated annualized gross revenues $69.0 million – 75% vesting 

Consolidated annualized gross revenues $77.5 million – 100% vesting 

Consolidated annualized gross revenues include revenue from Holzworth from acquisition date (February 7, 2020) forward, 
but  do  not  include  any  additional  acquisitions  from  February  7,  2020  forward.    Consolidated  annualized gross  revenues  is 
calculated on a calendar year basis (i.e. twelve months ended December 31).   

In accordance with ASC 718, compensation expense is recognized over the period from the date the performance conditions 
are determined to be probable of occurring through the implicit service period, which is the date the applicable conditions are 
expected to be met. If the performance conditions are not considered probable of being achieved, no expense is recognized 
until such time as the performance conditions are considered probable of being met, if ever. If the award is forfeited because 
the  performance  condition  is  not  satisfied,  previously  recognized  compensation  cost  is  reversed.  Management  evaluates 
performance conditions on a quarterly basis. The estimated implicit service period is April 2020 thru December 2025 for the 
April performance-based options and August 2020 thru December 2025 for the August performance-based options.

NOTE 11 - SEGMENT AND RELATED INFORMATION 

In June 2020, as a result of certain internal reorganizations completed over the prior six to nine months, the Company concluded 
it now operates as one reportable segment in accordance with ASC 280 Segment Reporting.  Prior to June 2020 the Company 
operated as three reportable segments.  In June 2020 we determined that the Chief Operating Decision Maker (“CODM”) as 
defined in ASC 280 evaluates operating results and makes decisions on how to allocate resources at the consolidated level.  
Although the CODM reviews key performance indicators including bookings, shipments and gross profit at a product group 
level, this information by itself is not sufficient enough to make operating decisions.  Rather, operating decisions are made 
based on review of consolidated profitability metrics rather than the individual results of each product group. 

NOTE 12 -  RETIREMENT PLAN 

The Company has a 401(k) profit sharing plan covering all eligible U.S. employees. Company contributions to the plan for the 
years ended December 31, 2020 and 2019 amounted to $44,000 and $286,000, respectively.

In 2020, the difference between the statutory and effective tax rate is due primarily to permanent differences between U.S. 
GAAP book income and taxable income including the goodwill impairment charge for the CommAgility reporting unit and the 
loss on contingent consideration related to the Holzworth earnout.  Additionally, in 2020 the difference between the statutory 
and effective tax rate was due to an increase in the state net operating loss valuation allowance and research and development 
deductions in the United Kingdom.  In 2019, the difference between the statutory and effective tax rate is due primarily to 
research and development deductions in the United Kingdom and a reduction in the state net operating loss valuation allowance.

Net deferred tax asset

The Company has domestic federal and state net operating loss carryforwards as of December 31, 2020 of approximately $16.3 
million and $42.4 million, respectively, which begin to expire in 2029.  $600,000 of the federal net operating loss carryforward 
and $1.6 million of state net operating loss carryforward has no expiration.  The Company also has foreign net operating loss 
carryforwards at December 31, 2020 of approximately $15.7 million for German trade tax purposes, which has no expiration.   

Realization of the Company’s deferred tax assets is dependent upon the Company generating sufficient taxable income in the 
appropriate tax jurisdictions in future years to obtain benefit from the reversal of net deductible temporary differences and from 
utilization of net operating losses. The Company’s valuation allowances of $7.7 million and $6.7 million at December 31, 2020 
and 2019, respectively, are associated with the Company’s foreign net operating loss carryforward from an inactive foreign 
entity, state net operating loss carryforward and a state research and development credit.   The amount of deferred tax assets 
considered  realizable  is  subject  to  adjustment  in  future  periods  if  estimates  of  future  taxable  income  are  changed.  As  of 
December 31, 2020, management believes that it is more likely than not that the Company will fully realize the benefits of its 
deferred tax assets associated with its domestic federal net operating loss carryforward. 

The Company does not have any significant unrecognized tax positions and does not anticipate a significant increase or decrease 
in unrecognized tax positions within the next twelve months. 

The Company has elected to record taxes related to the global intangible low-taxed income as a period cost.

NOTE 13 -  COMMITMENTS AND CONTINGENCIES 

Warranties 

The Company typically provides one to three year warranties on all of its products covering both parts and labor. The Company, 
at its option, repairs or replaces products that are defective during the warranty period if the proper preventive maintenance 
procedures have been followed by its customers.   

Legal Proceeding 

As previously disclosed, on June 5, 2019, L3Harris Corporation (“Harris”) filed a request for arbitration before the American 
Arbitration Association in accordance with the terms of an executed purchase order, statement of work and software license 
agreement  (collectively  referred  to  as  “Agreements”)  with  CommAgility  entered  into  in  2014.    Harris  claimed  that 
CommAgility breached the Agreements by offering for sale, marketing, and promoting techniques, capabilities, products and 
services that incorporate Work Product, as defined in the Agreements, owned by Harris.   In its arbitration demand, Harris 
claimed that CommAgility caused Harris significant monetary damages, the sum of which could not be determined until such 
time as discovery has been conducted but was estimated by Harris to be less than $250,000.  Harris did not include a request 
for monetary damages in its Statement of Claim, which was filed with the arbitration panel on May 22, 2020.  On December 
10, 2020, Harris released CommAgility from any and all claims that Harris may have had against CommAgility related to the 
Agreements before arbitration proceedings began.  In 2020, the Company incurred approximately $50,000 in legal expense 
related to this matter.  The remainder of legal expenses incurred in 2019 and 2020 related to this matter were covered under 
our professional indemnity insurance policy.     

Risks and Uncertainties 

The Company has been and continues to be unable to accurately predict the full impact that the COVID-19 Pandemic will have 
on our results of operations, financial condition, liquidity and cash flows due to numerous uncertainties, including the duration 
and severity of the pandemic and containment measures, the nature and length of actions taken by governments, businesses and 
individuals to contain or mitigate its impact, the severity and duration of the economic impact caused by the pandemic, the 
uncertainty  surrounding  possible  treatments  and  rollout  of  vaccines,  along  with  the  effectiveness  of  our  response.  Our 
compliance with containment and mitigation measures has impacted our day-to-day operations and is expected to continue to 
disrupt our business and operations, as well as that of our key customers, suppliers (including contract manufacturers) and other 
counterparties, at least through the third quarter of 2021. 

Proprietary information and know-how are important to the Company’s commercial success. There can be no assurance that 
others will not either develop independently the same or similar information or obtain and use proprietary information of the 
Company.  Certain  key  employees  have  signed  confidentiality  and  non-compete  agreements  regarding  the  Company’s 
proprietary information. 

The  Company  believes  that  its  products  do  not  infringe  the  proprietary  rights  of  third  parties.  There  can  be  no  assurance, 
however, that third parties will not assert infringement claims in the future. 

The Company’s deferred tax asset is recorded at tax rates expected to be in existence when those assets are utilized.  Should 
the tax rates change materially in the future the amount of deferred tax asset could be materially impacted.   

NOTE 15 – SUBSEQUENT EVENTS 

Second Amendment to Holzworth Share Purchase Agreement 

On February 19, 2021, the Company entered into the Second Amendment with Holzworth and Sellers.  The Second Amendment, 
among other things, converted the second deferred purchase price of $750,000 into unsecured seller notes with interest at an 
annual rate of 6.5% starting from April 1, 2021 until final payment. The payment date has been changed from March 31, 2021 
to three equal installments of $250,000, plus accrued interest, due on July 1, 2021, October 1, 2021 and January 1, 2022.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS 
Wireless Telecom Group, Inc. 

Additionally, the parties amended the payment dates of the earnout consideration. The payment date of the first earnout payment 
based on the financial results of the calendar year ended 2020 (“Year 1 Earnout”) has been amended from March 31, 2021 to (i) 
six (6) equal quarterly installments of 10% of the Year 1 Earnout payable on the last business day of each calendar quarter 
between June 30, 2021 and September 30, 2022 and (ii) one (1) installment payment equal to 40% of the Year 1 Earnout on 
December 31, 2022. The Year 1 Earnout is payable in cash or shares of the Company’s common stock based on the 90 trading 
day volume weighted average price immediately preceding final determination of the Year 1 Earnout or $2.19 per share.  The 
estimated payment for the Year 1 Earnout is $3.4 million which is recorded in accrued expenses and other current liabilities in 
the Consolidated Balance Sheet as of December 31, 2020.   

The parties also amended the provisions with respect to restrictions on transfer to adjust for the change in timing of earnout 
payments, as described above. Finally, the parties added a requirement that any earned but unpaid earnout consideration will 
be accelerated in the event the Company desires to enter into a material asset or equity acquisition in the future. 

Second Amendment to Muzinich Credit Agreement and Limited Waiver 

On February 25, 2021, the Company, its subsidiaries and Muzinich entered into Amendment 2, in which Muzinich agreed to 
waive  the  Company’s  obligation  to  comply  with  the  consolidated  leverage  ratio  and  fixed  charge  coverage  ratio  financial 
covenants in the Term Loan Facility for the fiscal quarter ending December 31, 2020. We were not in compliance with such 
covenants primarily as a result of the impact the COVID-19 pandemic had on our consolidated financial results.  Amendment 
2, among other things, amended the definition of consolidated EBITDA to include certain cash tax benefits related to our UK 
tax jurisdiction and reduced our consolidated leverage ratio for the twelve month periods ended September 30, 2021 from 3.00 
to  2.75,  December  31,  2021  from  2.75  to  2.25,  March  31,  2022  from  2.50  to  2.00  and  June  30,  2022  from  2.25  to  2.00. 
Additionally, the interest rate margin was increased from 7.25% to 9.25% effective January 1, 2021 and will step down to 
8.50% and 7.25% upon the Company achieving consolidated EBITDA on a trailing twelve-month basis of $4.0 million and 
$6.3 million, respectively. Muzinich and the Company also agreed on an excess cash flow payment of $428,000 and Muzinich 
provided consent for the Company to enter into the aforementioned notes with the Holzworth Sellers in the amount of $750,000, 
as described above. 

Amendment No. 7 to the Loan and Security Agreement with Bank of America, N.A. 

On February 25, 2021, the Company, its subsidiaries and Bank of America entered into Amendment No. 7 which revised the 
Credit Facility to accommodate the changes to the deferred purchase price payments to and notes with the Holzworth sellers 
as described above and provided Bank of America’s consent to the Company entering into the Muzinich Second Amendment, 
as described above.

Item 9A. Controls and Procedures 

(a) Evaluation of Disclosure Controls and Procedures 

Under the supervision and with the participation of our management, including our principal executive officer and principal 
financial officer, as of the end of the period covered by this report, we conducted an evaluation 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) under the Securities Act of 1934. Our 
disclosure controls and procedures are designed to provide reasonable assurance that the information required to be included in our SEC 
reports is recorded, processed, summarized and reported within the time periods specified in SEC rules and forms, relating to Wireless 
Telecom Group, Inc. Based on this evaluation, our principal executive officer and principal financial officer concluded that, as of the 
period covered by this report, our disclosure controls and procedures are effective. 

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

The  management  of  the  Company  is  responsible  for  establishing  and  maintaining  adequate  internal  control  over  financial 
reporting.  The  Company’s  internal  control  over  financial  reporting  is  a  process  designed  under  the  supervision  of  the  Company’s 
principal executive officer and principal financial officer to provide reasonable assurance regarding the reliability of financial reporting 
and the preparation of the Company’s financial statements for external purposes in accordance with U.S. GAAP. Because of its inherent 
limitations, internal control over financial reporting may not prevent or detect misstatements. All internal control systems, no matter 
how well designed, have inherent limitations. Therefore, even those systems determined to  be effective can provide only reasonable 
assurances with respect to financial statement preparation and presentation. Additionally, 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. 

As of December 31, 2020, management assessed the effectiveness of the Company’s internal control over financial reporting 
based on the criteria for effective internal control over financial reporting established in “Internal Control  — Integrated Framework,” 
issued  by  the  Committee  of  Sponsoring  Organizations  of  the  Treadway  Commission  (2013  framework).  Based  on  the  assessment, 
management determined that the Company maintained effective internal control over financial reporting as of December 31, 2020. 

This  annual  report  does  not  include  an  attestation  report  of  the  Company’s  independent  registered  public  accounting  firm 
regarding internal control over financial reporting. Management’s report was not subject to attestation by the Company’s independent 
registered public accounting firm pursuant to the Dodd-Frank Wall Street and Consumer Protection Act, which exempts non-accelerated 
filers and smaller reporting companies from the auditor attestation requirement of Section 404 (b) of the Sarbanes-Oxley Act. 

(c) Changes in Internal Controls over Financial Reporting 

  There have been no changes in our internal control over financial reporting that occurred during the last fiscal quarter that has 

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

Item 9B. Other Information
