We are a former blank check company that completed our initial public offering
on May 21, 2018. In March 2020, Grid Dynamics, formerly known as ChaSerg
Technology Acquisition Corp ("ChaSerg"), completed its acquisition of Grid
Dynamics International, Inc. ("GDI") pursuant to the business combination
agreement dated November 13, 2019 (the "Business Combination"). In conjunction
with the completion of the Business Combination, ChaSerg was renamed as Grid
Dynamics Holdings, Inc.



The Business Combination was accounted for as a reverse recapitalization for
which GDI was determined to be the accounting acquirer. Outstanding shares of
GDI were converted into our common shares, presented as a recapitalization, and
the net assets of ChaSerg were acquired at historical cost, with no goodwill or
other intangible assets recorded.

Recent Developments



In the three months ended December 31, 2020, our revenues were $30.1 million,
which included $1.0 million in revenue contribution from our recent acquisition
of Daxx Web Industries B.V. ("Daxx") completed on December 14, 2020. Excluding
the contribution from Daxx, in the three months ended December 31, 2020, our
revenues of $29.1 million were up 11% in comparison to the three months ended
September 30, 2020, and down 9% from the three months ended December 2019.
Overall, in the three months ended December 31, 2020, we witnessed healthy
business trends as reflected in the 11% sequential revenue growth over the three
months ended September 30, 2020. The three months ended December 31, 2020
quarter marked the second consecutive sequential quarter of revenue growth since
witnessing a bottom in revenues in the three months ended June 30, 2020. During
the quarter, we witnessed healthy customer demand across our industry verticals
as digital transformation initiatives continue to be a priority with our
customers. Furthermore, the ongoing global pandemic has been a catalyst for
companies to seek or accelerate enterprise-level digital initiatives that
include, but are not limited to, maintaining remote workforces, selling products
online, and creating continued efficiencies in business processes. During the
three months ended December 31, 2020, excluding Daxx, our largest industry
vertical was Technology, Media, and Telecom ("TMT") at 37% of our revenue, while
Consumer Packaged Goods (CPG)/Manufacturing, Finance, and Other verticals
contributed 21%, 10%, and 5% of our revenue, respectively.



We closed the twelve months ended December 31, 2020 with $111.3 million in
revenue, which included $1.0 million contributed by our recent acquisition of
Daxx. Excluding the contribution from Daxx, revenue of $110.3 million for the
twelve months ended December 31, 2020 was down from $118.3 million in the twelve
months ended December 31, 2019. The key reason for the year-over-year decline of
7% was disruptions caused to our Retail vertical which was negatively impacted
by the Covid-19 pandemic. Additionally, 2020 marked a significant shift in our
largest industry vertical. Unlike previous years, where our largest vertical was
Retail, in the twelve months ended December 31, 2020, our largest vertical was
Technology Media & Telecom. At 41% of our full year of 2020 revenue, the TMT
vertical grew by 40% on a year-over-year basis. While many customers positively
contributed to the year-over-year growth, Grid Dynamics' two largest customers
in 2020 (both in the TMT vertical) were the main contributors. We anticipate the
TMT vertical will continue to be our largest revenue contributing vertical

in
2021.



In the twelve months ended December 31, 2020, excluding the contribution from
Daxx, our Retail vertical contributed $34.0 million in revenue, down from $67.4
million in revenue in the twelve months ended December 31, 2019. In spite of the
year-over-year decline of approximately 50%, in the second half of 2020, we have
been witnessing a steady sequential pick up in business. For many of our retail
customers, the COVID-19 pandemic caused significant business disruption that
included closure of stores resulting in sales being severely impacted.
Furthermore, within our Retail vertical, since the beginning of the pandemic, we
have witnessed a shift towards retail customers who have embraced digital and
online commerce. This is a contrast to some of our other customers who have not
recovered from the impacts of the pandemic, and going forward, we expect that
some of them will not recover to pre-COVID levels.



We continue to focus on revenue diversification by increasing our customer base
with new logo additions. During the twelve months ended December 31, 2020, our
core Grid Dynamics business received revenues from a total of 52 customers and
added 16 new logos. Additionally, in the three months ended December 31, 2020
our core Grid Dynamics business exited the quarter with 43 paying customers, up
from 40 paying customers in the three months ended December 31, 2019.
Furthermore, during the three months ended December 31, 2020, our core Grid
Dynamics business added five new logos across industry verticals that included
Finance and TMT.



We closed the twelve months ended December 31, 2020 with GAAP Net loss of
$(12.6) million and $12.5 million, or 11.3% of revenue in Adjusted EBITDA, down
from GAAP Net income of $10.8 million and $23.7 million or 20% of revenue in
Adjusted EBITDA in the twelve months ended December 31, 2019. The year-over-year
decline was largely driven by a combination of factors that included lower
levels of revenue, increased general and administrative expenses associated with
operating as a publicly traded company, and increased headcount and personnel
costs.


Acquisition of Daxx Web Industries B.V.


On December 14, 2020, we acquired Netherland based Daxx Web Industries B.V.
("Daxx") in an all-cash transaction. Headquartered in Amsterdam, and with
approximately 490 employees, the company has engineering centers situated in
major tech hubs across Ukraine. Daxx has over 20 years of experience in
delivering software services to clients across a wide range of industry
verticals that include high-tech, digital media, healthcare, and education. Some
of its key capabilities of Daxx include consulting services spanning agile
process reengineering, lean development, and DevOps. Daxx serves customers in
the Netherlands, Germany, U.K., and the U.S., and has strong relationships with
high-growth start-ups and established software companies. We believe the
acquisition of Daxx will enable us to have a stronger foothold in Europe and
will enable the company to continue diversifying our business. In the three
months ended December 31, 2020, Daxx contributed $1.0 million in revenue.

COVID-19 Related Updates



In December 2019, a novel coronavirus COVID-19 was reported in China, and in
March 2020, the World Health Organization declared it a pandemic. This
contagious disease pandemic has continued to spread across the globe, including
extensively within the U.S., and is impacting worldwide economic activity and
financial markets, significantly increasing economic volatility and uncertainty.
In response to this global pandemic, several local, state, and federal
governments have been prompted to take unprecedented steps that include, but are
not limited to, travel restrictions, closure of businesses, social distancing,
and quarantines.



Starting in March 2020, headwinds to our business from the pandemic were largely
centered around our retail customers as many of them witnessed a slowdown in
their sales. After witnessing a low point in the month of May 2020, our retail
business has steadily improved as our retail customers resumed their operations
although we expect that some of our customers will not recover to pre-COVID
levels. We continue to take precautionary measures intended to minimize the risk
of the virus to our employees, our customers, and the communities in which we
operate that include suspension of all non-essential travel. Although a
significant proportion of our employees continue to work remotely, all our
facilities in the Central and Eastern Europe (CEE) region have been opened for
employees to work following local government guidelines. We continue to deliver
services to our customers in this fashion and this has resulted in minimal
disruption in our operational and delivery capabilities.



In the twelve months ended December 31, 2020, we have taken an allowance of $0.4
million doubtful accounts due to risks posed by the COVID-19 pandemic on our
customers' ability to make payments. We continue to be engaged with all our
customers regarding their ability to fulfill their payment obligations. In the
course of the three months ended December 31, 2020, we received payments from
multiple customers, including some of the higher risk retail customers.
Additionally, most of our customers who sought extended payment terms as the
pandemic unfolded have reverted back to their historical levels of payment
terms. We continue to review our accounts receivable on a regular basis and have
put in place processes to ensure payments from our customers.



Comparability of Financial Information

Grid Dynamics' results of operations and statements of assets and liabilities
may not be comparable between periods as a result of the Business Combination on
March 5, 2020 and the other events and transactions discussed below.



Key Performance Indicators and Other Factors Affecting Performance

Grid Dynamics uses the following key performance indicators and assesses the
following other factors to analyze its business performance, to make budgets and
financial forecasts and to develop strategic plans:



Employees by Region



Attracting and retaining the right employees is critical to the success of Grid
Dynamics' business and is a key factor in Grid Dynamics' ability to meet
customers' needs and grow its revenue base. Grid Dynamics' revenue prospects and
long-term success depend significantly on its ability to recruit and retain
qualified IT professionals. A substantial majority of Grid Dynamics' personnel
is comprised of such IT professionals.



The following table shows the number of Grid Dynamics personnel (including full-time and part-time employees and contractors serving in similar capacities) by region, as of the dates indicated:





                                      As of December 31,
                                 2020        2019        2018

As of December 31, 2020, there were 492 Daxx personnel including full-time

and part-time employees and contractors serving in similar capacities located


    in Ukraine and the Netherlands.




                                       32





Attrition



There is competition for IT professionals in the regions in which Grid Dynamics
operates, and any increase in such competition may adversely impact Grid
Dynamics' business and gross profit margins. Employee retention is one of Grid
Dynamics' main priorities and is a key driver of operational efficiency. Grid
Dynamics seeks to retain top talent by providing the opportunity to work on
exciting, cutting-edge projects for high profile clients, a flexible work
environment and training and development programs. Grid Dynamics' management
targets a voluntary attrition rate no higher than the mid-teen percentages,

in
line with the industry.



Hours and Utilization



As most of Grid Dynamics' customer projects are performed and invoiced on a time
and materials basis, Grid Dynamics' management tracks and projects billable
hours as an indicator of business volume and corresponding resource needs for IT
professionals. To maintain its gross profit margins, Grid Dynamics must
effectively utilize its IT professionals, which depends on its ability to
integrate and train new personnel, to efficiently transition personnel from
completed projects to new assignments, to forecast customer demand for services
and to deploy personnel with appropriate skills and seniority to projects. Grid
Dynamics' management generally tracks utilization with respect to subsets of
employees, by location or by project, and calculates the utilization rate for
each subset by dividing (x) the aggregate number of billable hours for a period
by (y) the aggregate number of total available hours for the same period. Grid
Dynamics' management analyzes and projects utilization to measure the efficiency
of its workforce and to inform management's budget and personnel recruiting

decisions.



Customer Concentration


Grid Dynamics' ability to retain and expand its relationships with existing
customers and add new customers are key indicators of its revenue potential.
Excluding Daxx, Grid Dynamics grew its customer base from 40 customers in 2019
to 52 customers in 2020. Grid Dynamics' procurement of new customers has a
direct impact on its ability to diversify its sources of revenue and replace
customers that may no longer require its services. Grid Dynamics has a
relatively high level of revenue concentration with certain customers. Of Grid
Dynamics' customers, two customers each accounted for 10% or more of Grid
Dynamics' revenue in the year ended December 31, 2020 and three customers each
accounted for 10% or more of Grid Dynamics' revenue in the year ended December
31, 2019.



The following table shows the evolution of Grid Dynamics' customer base and
revenue concentration, as of the dates and for the annual periods indicated:



                                                                   Year ended December 31,

Foreign Currency Exchange Rate Exposure

Grid Dynamics is exposed to foreign currency exchange rate risk and its profit
margins are subject to volatility between periods due to changes in foreign
currency exchange rates relative to the U.S. dollar. Grid Dynamics' functional
currency, as well as the functional currency of all of its subsidiaries, is the
U.S. dollar. Grid Dynamics contracts with customers for payment in and generates
substantially all of its revenue in U.S. dollars. Its non-U.S. subsidiaries'
operations relate substantially to performing services under those contracts.
Several of Grid Dynamics' subsidiaries conduct operations and employ or contract
personnel in Russia, Ukraine, Poland and Serbia, but keep their books and
records in U.S. dollars. Grid Dynamics' foreign currency transaction exposure is
a result of having to convert U.S. dollars into the local currencies of the
countries in which it must pay expenses, typically by transferring funds to its
non-U.S. subsidiaries. These expenses are primarily comprised of compensation
and benefits and other operating costs, such as rent. Subsidiary transactions
executed in local currencies are converted into U.S. dollars at the exchange
rate in effect on the date of the transaction, in the case of asset and
liability transactions, or at the average monthly exchange rate, in the case of
income and expense transactions. Certain balances in local currencies,
particularly cash and financial instruments, are adjusted at each balance sheet
date to reflect the then-current exchange rate, which is the rate at which the
related receivable or payable could be settled at that date. As a result, Grid
Dynamics' assets, liabilities, profit margins and other measures of
profitability may be subject to volatility due to changes in the exchange rate
of the U.S. dollar against the currencies in which Grid Dynamics' subsidiaries
incur operating expenses, hold assets or owe liabilities, and may not be
comparable between periods.



For the twelve months ended December 31, 2020, approximately 14%, 12%, and 10%
of Grid Dynamics' $126.7 million of combined cost of revenue and total operating
expenses were denominated in the Russian rouble, Ukrainian hryvnia and Polish
zloty, respectively. Comparatively, for the year ended December 31, 2019,
approximately 22%, 13%, and 12% of Grid Dynamics' $102.7 million of combined
cost of revenue and total operating expenses were denominated in the Russian
rouble, Ukrainian hryvnia and Polish zloty, respectively. Grid Dynamics does not
currently hedge its foreign currency exposure, although it seeks to minimize
such exposure by limiting cash transfers to amounts necessary to fund subsidiary
operating expenses for a short period, typically one to two weeks. When and
where possible, Grid Dynamics seeks to match expenses to the U.S. dollar. For
example, in Ukraine, Grid Dynamics generally pays salaries in the current
hryvnia equivalent of an agreed U.S. dollar amount, consistent with local
requirements. As a result, a significant portion of Grid Dynamics' exposure to
fluctuations in the value of the Ukrainian hryvnia against the U.S. dollar is
naturally hedged. Management carefully evaluates its exposure to foreign
currency risk and, though Grid Dynamics does not currently hedge this exposure
through the use of financial instruments, it may do so in the future. See Item
7A, "Quantitative and Qualitative Disclosures about Market Risk-Foreign Currency
Exchange Rate Risk" below for more information about Grid Dynamics' exposure to
foreign currency exchange rates.



Seasonality



Grid Dynamics' business is subject to seasonal trends that impact its revenues
and profitability between quarters. Some of the factors that influence the
seasonal trends include the timing of holidays in the countries in which Grid
Dynamics operates and the U.S. retail cycle, which drives the behavior of Grid
Dynamics' retail customers. Excluding the impact of growth in its book of
business, Grid Dynamics has historically recorded higher revenue and gross
profit in the second and third quarters of each year compared to the first and
fourth quarters of each year. The Christmas holiday season in Russia and
Ukraine, for example, falls in the first quarter of the calendar year, resulting
in reduced activity and billable hours. In addition, many of Grid Dynamics'
retail sector customers tend to slow their discretionary spending during the
holiday sale season, which typically lasts from late November (before
Thanksgiving) through late December (after Christmas).



Non-GAAP Measures



To supplement Grid Dynamics' consolidated financial data presented on a basis
consistent with U.S. GAAP, this Annual Report contains certain non-GAAP
financial measures, including Adjusted EBITDA, Non-GAAP Net Income and Non-GAAP
Diluted Earnings Per Share, or EPS. Grid Dynamics has included these non-GAAP
financial measures because they are financial measures used by Grid Dynamics'
management to evaluate Grid Dynamics' core operating performance and trends, to
make strategic decisions regarding the allocation of capital and new investments
and are among the factors analyzed in making performance-based compensation
decisions for key personnel. These measures exclude certain expenses that are
required under U.S. GAAP. Grid Dynamics excludes these items because they are
not part of core operations or, in the case of stock-based compensation,
non-cash expenses that are determined based in part on Grid Dynamics' underlying
performance.



Grid Dynamics believes these supplemental performance measurements are useful in
evaluating operating performance, as they are similar to measures reported by
its public industry peers and those regularly used by security analysts,
investors and other interested parties in analyzing operating performance and
prospects. These non-GAAP financial measures are not intended to be a substitute
for any GAAP financial measures and, as calculated, may not be comparable to
other similarly titled measures of performance of other companies in other
industries or within the same industry.



                                       34





There are significant limitations associated with the use of non-GAAP financial
measures. Further, these measures may differ from the non-GAAP information, even
where similarly titled, used by other companies and therefore should not be used
to compare our performance to that of other companies. Grid Dynamics compensates
for these limitations by providing investors and other users of its financial
information a reconciliation of non-GAAP measures to the related GAAP financial
measures. Grid Dynamics encourages investors and others to review its financial
information in its entirety, not to rely on any single financial measure and to
view its non-GAAP measures in conjunction with GAAP financial measures.



Grid Dynamics defines and calculates its non-GAAP financial measures as follows:

proportion of Earnout Shares outstanding. The number of Earnout Shares

outstanding was 0.8 million.

(6) Non-GAAP Diluted EPS is calculated by dividing Non-GAAP Net Income/(Loss) by

the diluted weighted-average shares outstanding. From the three months ended

December 31, 2020 onwards, we have chosen to calculate its Non-GAAP Diluted

EPS based on the diluted share count even in Net GAAP Loss situation. This

methodology differs from the prior approach when we applied the basic share

count in situations of a Net GAAP Loss and a positive Non-GAAP Net Income.

Management believes that the new methodology provides better representation

of the company's financial results as it takes into account the significance

of the dilutive impact from any outstanding equity instruments in a GAAP Net


    Loss/Non-GAAP Net Income situation.



Key Components of Revenue and Expenses





Revenue



Grid Dynamics generates revenue by providing focused and complex services in the
area of software engineering, development, integration, testing, and operations
of digital services. Grid Dynamics provides services mainly on a time and
materials basis and, to a much lesser extent, on a fixed-fee basis. While
fixed-fee contracts currently represent an immaterial portion of overall revenue
for the periods presented, Grid Dynamics expects proportionate revenue from
fixed-fee contracts to increase in future periods. On a time and materials
basis, Grid Dynamics earns and recognizes revenue as hours and costs are
incurred. On its current and future fixed fee contracts, Grid Dynamics earns and
recognizes revenue as the work is performed, the monthly calculation of which is
based upon actual labor hours incurred and level of effort expended throughout
the duration of the contract. For both time and materials contracts and fixed
fee contracts, hourly rates are typically determined based on the location and
experience of Grid Dynamics personnel selected to perform the service and are
negotiated for each contract or statement of work, as the case may be. For fixed
fee contracts, the fixed fee generally remains constant for the contracted
project period unless the customer directs a change in scope of project work or
requests additional Grid Dynamics employees in excess of those scheduled for a
specific project.



In select cases, Grid Dynamics offers volume discounts or early settlement
discounts, which are recorded as contra-revenue items. Volume discounts apply
once the customer reaches certain contractual spend thresholds. Early settlement
discounts are issued contingent upon the timing of the payment from the
customer. If there is uncertainty about project completion or receipt of payment
for services provided, revenue is deferred until the uncertainty is sufficiently
resolved.



                                       36





Costs and Expenses



Cost of Revenue. Cost of revenue consists primarily of salaries and employee
benefits, including performance bonuses and stock-based compensation, and travel
expenses for client-serving personnel. Cost of revenue also includes
depreciation and amortization expense related to client-serving activities.



Engineering, Research and Development. Engineering, research and development
expenses consist mainly of salaries and employee benefits including performance
bonuses and stock-based compensation for personnel engaged in the design and
development of solutions. Engineering, research and development expenses also
include depreciation and amortization expenses related to such activities.
Engineering, research and development costs are expensed as incurred.



Sales and Marketing. Sales and marketing expenses consist primarily of expenses
associated with promoting and selling Grid Dynamics' services and consists
mainly of salaries and employee benefits, including performance bonuses and
stock-based compensation, marketing events, travel, as well as depreciation and
amortization expenses related to such activities.



General and Administrative. General and administrative expenses consist
primarily of administrative personnel and officers' salaries and employee
benefits including performance bonuses and stock-based compensation, legal and
audit expenses, insurance, operating lease expenses (mainly facilities and
vehicles) and other facility costs, workforce global mobility initiatives,
restructuring and employee relocations cost (not in connection with customer
projects), and depreciation and amortization expenses related to such
activities. General and administrative expenses include a substantial majority
of Grid Dynamics' stock-based compensation costs for the financial periods
discussed herein.



Provision for Income Taxes. Grid Dynamics follows the asset and liability method
of accounting for income taxes, whereby deferred income taxes are recognized for
the tax consequences of temporary differences between the financial statement
carrying amounts and the tax basis of the assets and liabilities. The provision
for income taxes reflects income earned and taxed in the various U.S. federal
and state and non-U.S. jurisdictions. Jurisdictional tax law changes, increases
or decreases in permanent differences between book and tax items, accruals or
adjustments of accruals for tax contingencies or valuation allowances, and the
change in the mix of earnings from these taxing jurisdictions all affect the
overall effective tax rate. Grid Dynamics' effective tax rate was 17%, 30%, and
29% in the years ended December 31, 2020, 2019 and 2018, respectively. The
differences in effective tax rate between the years ended December 31, 2020 and
2019 and 2018 were attributable mainly to stock based compensation excess tax
benefit, partially offset by Section162(m) compensation deduction limitations.

(1) Includes Daxx




Revenue. Revenue decreased by $7.0 million, or 6.0%, to $111.3 million in 2020
from $118.3 million in 2019. The key reason for the year-over-year decline was
the decline in revenues from Retail customers impacted by the COVID-19 pandemic.
This decline in Retail business was offset by increase in revenue from other
industry verticals such as TMT, CPG/Manufacturing, and Other. For the year ended
December 31, 2020, retail revenues were $34.0 million, down from $67.4 million
in the same period a year ago. The 50% year-over-year decline in retail revenues
was partially offset by revenues of the other segments that, on a combined
basis, grew from $51.0 million in the year ended December 31, 2019 to $77.3
million in the year ended December 31, 2020. Additionally, Grid Dynamics' top
ten customers contributed $87.2 million and $102.6 million to revenue for the
years ended December 31, 2020 and 2019, respectively, in the aggregate
accounting for $15.4 million of the decrease. The remainder of the other
industry verticals increase  reflected growth in revenue from new customers
(i.e., customers for which Grid Dynamics performed services for the first time
during the period) and other existing customers.



Cost of Revenue and Gross Profit. Cost of revenue decreased by $0.4 million, or
0.6%, to $69.7 million in 2020 from $70.1 million in 2019 reflecting a decrease
in revenue offset by higher retention bonuses resulting from the Business
Combination and stock-based compensation expenses.



Gross profit decreased by $6.6 million, or 13.7%, to $41.6 million in 2020 from
$48.2 million in 2019. Gross margin (gross profit as a percentage of revenue)
decreased by 3.4 percentage points to 37.4% in the year ended December 31, 2020
from 40.8% in the year ended December 31, 2019. The gross margin decline was
attributable to a combination of increased costs associated with stock-based
compensation and retention bonuses resulting from the Business Combination and
lower levels of revenue in the year ended December 31, 2020 due to the impacts
of the ongoing COVID-19 pandemic.



Engineering, Research and Development. Engineering, research and development
expenses increased by $5.0 million to $9.3 million in the year ended December
31, 2020, a 114.2% increase from $4.3 million in the year ended December 31,
2019. The increase was primarily due to a combination of enhanced efforts around
engineering and development projects, Grid Dynamics' efforts to develop its
solutions and expertise, reallocation of delivery personnel to strategic R&D
initiatives, costs associated with stock-based compensation, and retention
bonuses resulting from the Business Combination.



Sales and Marketing. Sales and marketing expenses increased by $3.1 million, or
44.7%, to $10.1 million in the year ended December 31, 2020 from $6.9 million in
the year ended December 31, 2019. Sales and marketing expenses accounted for
9.0% of Grid Dynamics' revenue in the year ended December 31, 2020 compared to
5.9% in the year ended December 31, 2019, an increase of 3.1 percentage points.
The increase was due mainly to the increased costs associated with stock-based
compensation and retention bonuses resulting from the Business Combination and
partially offset by decrease in marketing and sales events due to the COVID-19
pandemic.



General and Administrative. General and administrative expenses increased by
$16.4 million, or 76.9%, to $37.7 million in the year ended December 31, 2020
from $21.3 million in the year ended December 31, 2019. Increased stock-based
compensation accounted for approximately $11.1 million of the increase. The
remaining portion of the increase was due mainly to the retention bonuses
resulting from the Business Combination. As a result, general and administrative
expenses accounted for 33.9% of Grid Dynamics' revenue in the year ended
December 31, 2020, an increase of 15.9 percentage points from 18.0% in the

year
ended December 31, 2019.


Other income/(expenses), net. Other net income/(expenses) increased to $0.2 million for the year ended December 31, 2020 from $(0.2) million for the year ended December 31, 2019, mainly due to interest and other income offset by miscellaneous expenses.





                                       38




Provision/(benefit) for Income Tax. Provision/(benefit) for income tax was $(2.6) million in the year ended December 31, 2020 compared to $4.6 million in the year ended December 31, 2019. The effective tax rate decreased by 13% between periods. See "-Key Components of Revenue and Expenses-Costs and Expenses-Provision for Income Taxes."





Net Income/(loss). Net income/(loss) decreased to $(12.6) million in the year
ended December 31, 2020 from $10.8 million in the year ended December 31, 2019
for the reasons discussed above.

Revenue. Revenue increased by $26.4 million, or 28.8%, to $118.3 million in 2019
from $91.9 million in 2018. Grid Dynamics' top ten customers contributed $102.6
million and $86.6 million to revenue for the year ended December 31, 2019 and
2018, respectively, in the aggregate accounting for $16.0 million of the
increase despite a decline in revenue from one of Grid Dynamics' top five
customers due to cost-cutting initiatives. The remainder of the increase
reflected growth in revenue from new customers (i.e., customers for which Grid
Dynamics performed services for the first time during the period), which
accounted for an additional $6.9 million of the increase, and other existing
customers. The entire revenue increase was driven primarily by increased
business volume, as well as a slight increase to average rates.



Cost of Revenue and Gross Profit. Cost of revenue increased by $17.5 million, or 33.4%, to $70.1 million in 2019 from $52.6 million in 2018 reflecting Grid Dynamics' increased business volume.


Gross profit increased by $8.9 million, or 22.7%, to $48.2 million in 2019 from
$39.3 million in 2018. Gross margin (gross profit as a percentage of revenue)
decreased by 2.0 percentage points to 40.8% in the year ended December 31, 2019
from 42.8% in the year ended December 31, 2018. The gross margin decline was
attributable mainly to a change in employee mix, reflecting Grid Dynamics'
expansion in Poland and an increase in the ratio of U.S.-based to non-U.S.-based
personnel engaged in performing Grid Dynamics' customer contracts. These trends
reflect Grid Dynamics' commitment to staffing its increasingly complex projects
with appropriately experienced personnel. Grid Dynamics' U.S. and Poland based
employees are billed at higher hourly rates and generate more gross profit
dollars per hour than professionals in other Grid Dynamics locations. However,
the costs of these U.S. and Poland based employees are also higher and,
therefore, they generate modestly lower gross margins.



Engineering, Research and Development. Engineering, research and development
expense increased by $1.7 million to $4.3 million in the year ended December 31,
2019, a 64.4% increase from $2.6 million in the year ended December 31, 2018,
reflecting Grid Dynamics' efforts to develop its solutions and expertise.



Sales and Marketing. Sales and marketing expense increased by $1.7 million, or
33.6%, to $6.9 million in the year ended December 31, 2019 from $5.2 million in
the year ended December 31, 2018. Sales and marketing expense accounted for 5.9%
of Grid Dynamics' revenue in the year ended December 31, 2019 compared to 5.7%
in the year ended December 31, 2018, an increase of 0.2 percentage points. The
increase was due mainly to the development of Grid Dynamics' sales force
personnel and ramp up in marketing events, starting in mid-2018.



                                       39





General and Administrative. General and administrative expense increased by $3.7
million, or 20.9%, to $21.3 million in the year ended December 31, 2019 from
$17.6 million in the year ended December 31, 2018. Labor, bonus, and vacation
costs accounted for approximately $1.2 million of the increase, consistent with
the increase in headcount. In addition, we renewed certain operating leases for
corporate office rent accounting for an additional $1.0 million. Stock-based
compensation accounted for an additional $0.7 million. The remainder of the
increase was attributable to Grid Dynamics' relocation of personnel, increased
spend on workforce global mobility initiatives, increased acquisition-related
exploratory costs, an increase in other travel-related costs and human-resources
expenses. As a result, general and administrative expense accounted for 18.0% of
Grid Dynamics' revenue in the year ended December 31, 2019, a decrease of 1.2
percentage points from 19.2% in the year ended December 31, 2018.



Other income/(expenses), net. Other net expenses decreased to $0.2 million for
the year ended December 31, 2019 from $0.7 million for the year ended December
31, 2018, reflecting increased interest income and a reduction in miscellaneous
expenses.



Provision/(benefit) for Income Tax. Provision/(benefit) for income tax was $4.6
million in the year ended December 31, 2019 compared to $3.9 million in the year
ended December 31, 2018. The effective tax rate increased by 0.5 percentage
points between periods. See "- Key Components of Revenue and Expenses - Costs
and Expenses - Provision for income tax."



Net Income/(loss). Net income/(loss) increased to $10.8 million in the year ended December 31, 2019 from $9.2 million in the year ended December 31, 2018 for the reasons discussed above.

Liquidity and Capital Resources

Grid Dynamics measures liquidity in terms of its ability to fund the cash
requirements of its business operations, including working capital needs,
capital expenditures, contractual obligations and other commitments with cash
flows from operations and other sources of funding. Grid Dynamics' current
liquidity needs relate mainly to compensation and benefits of Grid Dynamics'
employees and contractors and capital expenditures for computer hardware and
office furniture. Grid Dynamics' ability to expand and grow its business will
depend on many factors including its capital expenditure needs and the evolution
of its operating cash flows. Grid Dynamics may need more cash resources due to
changed business conditions or other developments, including investments or
acquisitions. Grid Dynamics believes that its current cash position on its
balance sheet of $112.7 million is sufficient to fund its currently expected
levels of operating, investing and financing expenditures for a period of twelve
months from the date of this filing. However, if Grid Dynamics' resources are
insufficient to satisfy its cash requirements, it may need to seek additional
equity or debt financing, which may be subject to conditions outside of Grid
Dynamics' control and may not be available on terms acceptable to Grid Dynamics'
management or at all.



As of December 31, 2020, Grid Dynamics had cash and cash equivalents amounting
to $112.7 million (compared to $42.2 million at December 31, 2019). Of this
amount, $3.1 million was held outside the United States, namely in Russia,
Ukraine, Poland, Serbia and the Netherlands (compared to $2.2 million as of
December 31, 2019). As many of Grid Dynamics' assets, operations and employees
are located in these countries, Grid Dynamics expects that all such cash and
cash equivalents will be used to fund future operating needs and Grid Dynamics'
management has no intention of repatriating the funds. If Grid Dynamics decided
to remit funds from these countries to the United States in the future, whether
in the form of inter-company dividends or otherwise, they may be subject to
foreign withholding taxes. In addition, Grid Dynamics' cash in banks in Russia,
Ukraine, Poland and Serbia may be subject to other risks, as the banking sector
in certain of these countries is subject to periodic instability, may be subject
to sanctions and may be subject to capital adequacy and other banking standards
that are substantially less rigorous than those of the United States.



Grid Dynamics does not have any debt outstanding as of December 31, 2020 and did not have any debt outstanding at any balance sheet date presented.





Our performance stock units, or PSUs, vest upon the satisfaction of a
performance-based vesting condition. The compensation committee of our board of
directors determined that the performance conditions of the PSUs were met as of
February 12, 2021. Approximately 0.7 million shares were issued upon vesting of
the PSUs and 0.75 million shares were net withheld to cover $10.7 million tax
withholding and remittance obligations. The first vesting event for our
restricted stock units, or RSUs, will also occur on March 13, 2021, at which
time approximately 0.6 million shares underlying RSUs held by our officers and
employees will vest and settle into shares of our common stock. We currently
expect that the average withholding tax rate for individuals holding our RSUs
will be approximately 52%. We have determined that our policy will be to require
individuals to withhold to cover, so approximately 52% of the vested shares
would be withheld on the settlement date, with the equivalent value being paid
by us from our working capital. If the price of our common stock at the time of
settlement of the RSUs in the first quarter of 2021 were equal to the share
price that triggered the vesting of the PSUs, or $14.33 per share, we estimate
that this tax withholding obligation in the first quarter of 2021 would be
approximately be $15.0 million in the aggregate.

Cash Flows



The following table summarizes Grid Dynamics' cash flows for the annual periods
indicated:



                                                  Year ended December 31,

Operating Activities. Net cash provided by operating activities during the year
ended December 31, 2020 decreased by $6.6 million, or 52.7%, to $5.9 million
from $12.5 million in the same period in 2019, driven by lower cash operating
profit (before non-cash depreciation and amortization and stock-based
compensation charges). The key reasons for the decline in net cash provided by
operating activities were retention bonuses paid out to employees due to the
successful Business Combination on March 5, 2020, lower level of revenues due to
the impact of the COVID-19 pandemic in the period of March through September 30,
2020, and higher costs associated with our delivery centers.



Net cash provided by operating activities during the year ended December 31,
2019 increased by $1.9 million, or 18.4%, to $12.5 million from $10.6 million in
the same period in 2018, driven by higher operating profit ($2.3 million
increase year-on-year) as well as higher non-cash operating costs, particularly
depreciation and amortization and stock-based compensation charges, offset by
increases in prepaid expenses and deferred transaction costs.



Investing Activities. Net cash used in investing activities during the year
ended December 31, 2020 was $18.3 million compared to $2.8 million in cash used
in the same period in 2019, due primarily to cash paid for the Daxx acquisition
in the year ended December 31, 2020 as well as capital expenditures for computer
hardware and related equipment in both periods.



Net cash used in investing activities during the year ended December 31, 2019
was $2.8 million compared to $3.1 million in cash used in the same period in
2018, and in both periods reflected mainly capital expenditures for computer
hardware and related equipment.



Financing Activities. Net cash provided by financing activities was $83.0
million in the year ended December 31, 2020, reflecting primarily the proceeds
from the Business Combination. Net cash provided by financing activities was
$14.6 million in the year ended December 31, 2019 reflecting primarily $14.9
million in proceeds from the sale of common and preferred stock and $1.7 million
in proceeds from stock option grant exercises in 2019, partially offset by
dividends paid of $2.0 million.



Net cash provided by financing activities was $14.6 million in the year ended
December 31, 2019, reflecting primarily $14.9 million in proceeds from the sale
of common and preferred stock and $1.7 million in proceeds from stock option
grant exercises in 2019, offset by dividends paid of $2.0 million. Grid Dynamics
had substantially no cash flows from or used in financing activities in the

year
ended December 31, 2018.



Contractual Obligations


The following table and the information that follows summarizes Grid Dynamics' contractual obligations as of December 31, 2020.

Dynamics also has 20 lease agreements for facilities in Texas, the US,

Russia, Poland, Serbia, the Netherlands, and Ukraine, under leases expiring

between January 2021 and August 2023.

(2) Grid Dynamics entered into one non-cancelable software services agreement

with a term of five years. Payments are due quarterly in advance beginning

March 1, 2020.



Grid Dynamics' outstanding operating leases and software service agreement obligations have not changed materially since December 31, 2020. In addition, Grid Dynamics purchases software licenses in the ordinary course of business.

Non-perpetual licenses are typically renewed annually. Grid Dynamics does not have any material obligations under contractual arrangements other than as disclosed in this Annual Report.





                                       41




Off-Balance Sheet Arrangements and Commitments





Except for its credit support for the letter of credit and balances on corporate
credit cards, Grid Dynamics does not have any off-balance sheet arrangements of
the kind required to be disclosed under SEC rules and does not have any
off-balance sheet or contingent commitments, except as described above with
respect to operating leases.



As a result of analysis related to Grid Dynamics' functional control of
subcontractor GD Ukraine, LLC, the subcontractor was determined to be a variable
interest entity ("VIE") and is therefore consolidated in Grid Dynamics'
financial statements. The assets and liabilities of this VIE consist primarily
of intercompany balances and transactions, all of which have been eliminated in
consolidation.



Critical Accounting Policies



Grid Dynamics management's discussion and analysis of our financial condition
and results of operations is based on the consolidated financial statements,
which have been prepared in accordance with U.S. GAAP. Preparation of the
financial statements requires Grid Dynamics to make judgments, estimates and
assumptions that impact the reported amount of revenue and expenses, assets and
liabilities and the disclosure of contingent assets and liabilities. Grid
Dynamics considers an accounting judgment, estimate or assumption to be critical
when (1) an estimate or assumption is complex in nature or requires a high
degree of judgment, and (2) the use of different judgments, estimates and
assumptions could have a material impact on Grid Dynamics' consolidated
financial statements. Grid Dynamics' critical accounting policies are described
in Note 2 to its consolidated financial statements.



Revenue



Grid Dynamics derives substantially all of its revenue through time and
materials contracts. Fixed-fee customer contracts, although not significant
historically, will comprise a more significant portion of revenue in future
periods. For all contracts, Grid Dynamics uses master agreements that govern the
overall relevant terms and conditions of the business arrangement and executes
statements of work pursuant to such agreements to execute specific projects.
Grid Dynamics recognizes revenue for services over time as hours are incurred by
Grid Dynamics' engineering personnel. For all contracts, the customer derives
value from the Company providing daily consulting services, and the value
derived corresponds to the labor hours expended. Therefore, the Company measures
the progress and recognizes revenue using an effort-based input method.



Grid Dynamics also offers volume discounts or early settlement discounts. Volume
discounts apply once the customer reaches certain contractual spend thresholds.
Early settlement discounts are issued contingent upon the timing of the payment
from the customer. If the consideration promised in a contract includes a
variable amount, Grid Dynamics only includes estimated amounts of consideration
in the transaction price to the extent it is probable that a significant
reversal of cumulative revenue recognized will not occur when the uncertainty
associated with the variable consideration is resolved.



Income Taxes



The determination of the provision for income taxes requires significant
judgment, the use of estimates and the interpretation and application of complex
tax laws. The provision for income taxes reflects a combination of income earned
and taxed in the various U.S. federal and state and non-U.S. jurisdictions.
Changes in tax law, increases or decreases in permanent differences between book
and tax items, accruals or adjustments of accruals for tax contingencies or
valuation allowances, and the change in the mix of earnings across taxing
jurisdictions all affect the overall effective tax rate.



In assessing the realizability of deferred tax assets, Grid Dynamics considers
whether it is more-likely-than-not that some portion, or all, of the deferred
tax assets will not be realized. Management considers all available evidence,
both positive and negative, in determining whether a valuation allowance is
required, including prior earnings history, the scheduled reversal of deferred
tax liabilities, projected future taxable income, carryback and carryforward
periods of tax attributes and tax planning strategies that could potentially
enhance the likelihood of realization of a deferred tax asset in making this
assessment. The weight given to the positive and negative evidence is
commensurate with the extent to which the evidence may be objectively verified.



Grid Dynamics evaluates for uncertain tax positions at each balance sheet date.
When it is more likely than not that a position will be sustained upon
examination by a tax authority that has full knowledge of all relevant
information, Grid Dynamics measures the amount of tax benefit from the position
and records the largest amount of tax benefit that is greater than 50% likely of
being realized after settlement with a tax authority. Grid Dynamics' policy for
interest and/or penalties related to underpayments of income taxes is to include
interest and penalties in provision for income tax.



                                       42





Business Combinations



The Company accounts for business combinations under the acquisition method of
accounting, in accordance with Accounting Standards Codification ("ASC") Topic
805, Business Combinations, recording any assets acquired and liabilities
assumed based on their respective fair values. Any excess of the fair value of
purchase consideration over the fair value of the assets acquired less
liabilities assumed is recorded as goodwill. The Company uses management
estimates and industry data to assist in establishing the acquisition date fair
values of assets acquired, liabilities assumed, and contingent consideration
granted, if any. These estimates and valuations require the Company to make
significant assumptions, including projections of future events and operating
performance.



Stock-based Compensation



Grid Dynamics has in the past issued, currently issues and intends to continue
issuing incentive stock options and non-qualifying stock options, performance
stock units and restricted stock units. While Grid Dynamics does not currently
have any other form of stock-based awards outstanding, it may also issue stock
appreciation rights. Stock-based compensation expense is measured based on the
grant-date fair value of the share-based awards. Forfeitures are recognized as
incurred. Grid Dynamics estimates grant date fair value of its stock using a
number of objective and subjective factors, as described in more detail below,
and the Black-Scholes option pricing model to estimate the grant date fair value
of option grants. The model requires management to make a number of key
assumptions, including expected volatility, expected term, risk free interest
rate and expected dividends. As Grid Dynamics' shares do not  have sufficient
trading history, expected volatility is estimated based on the average
historical volatility of similar entities with publicly traded shares. The risk
free rate for the expected term of the option is based on the U.S. Treasury
yield curve at the date of grant. The expected term is estimated using the
simplified method, which takes into account vesting and contractual term. Grid
Dynamics' options grants generally vest over a 4-year period and from time to
time Grid Dynamics makes grants with a portion vesting at the time of grant.
Management elected to use the simplified method instead of historical experience
due to a lack of relevant historical data resulting from changes in option
vesting schedules and changes in the pool of employees receiving option grants.
Grid Dynamics evaluates the assumptions used to value its stock-based awards on
each grant date. Grants are approved by Grid Dynamics' Board of Directors.



Grid Dynamics amortizes the grant date fair value of all stock-based
compensation awards over the employee's requisite service period for the entire
award on a straight-line basis, which is generally the vesting period. For an
award with graded vesting that is subject only to a service condition (e.g.,
time-based vesting), Grid Dynamics uses the straight-line attribution method
under ASC 718, under which it recognizes compensation cost on a straight-line
basis over the total requisite service period for the entire award.
Additionally, Grid Dynamics applies the "floor" concept, so that the amount of
compensation cost that is recognized as of any date is at least equal to the
grant-date fair value of the vested portion of the award on that date. In other
words, if the straight-line expense recognized to date is less than the grant
date fair value of the award that is legally vested at that date (for example,
as a result of a portion of a grant vesting at the grant date), Grid Dynamics
will increase its recognized expense to at least equal the fair value of the
vested amount. The fair market value of Grid Dynamics stock is determined based
on the closing price on NASDAQ on the measurement date. For more detailed
information about Grid Dynamics' historical and outstanding grants and its
valuation of its stock-based compensation and awards, see Note 10 to the audited
consolidated financial statements included elsewhere in this Annual Report.

Emerging Growth Company Accounting Election


Section 102(b)(1) of the Jumpstart Our Business Startups Act of 2012 ("JOBS
Act") exempts emerging growth companies from being required to comply with new
or revised financial accounting standards until private companies are required
to comply with the new or revised financial accounting standards. The JOBS Act
provides that a company can choose not to take advantage of the extended
transition period and comply with the requirements that apply to non-emerging
growth companies and any such election to not to take advantage of the extended
transition period is irrevocable. Prior to the Business Combination, ChaSerg was
an "emerging growth company" as defined in Section 2(a) of the Securities Act
and has elected to take advantage of the benefits of this extended transition
period. Following the consummation of the Business Combination, Grid Dynamics
remains an emerging growth company and continues to take advantage of the
benefits of the extended transition period.



Recently Adopted and Issued Accounting Pronouncements

Recently issued and adopted accounting pronouncements are described in Note 2 to Grid Dynamics' consolidated financial statements.


In particular, Grid Dynamics implemented Accounting Standards Codification (ASC)
Topic 606 (Revenue from Contracts with Customers) in January 2019. Grid Dynamics
adopted the standard using the modified retrospective method, where it
recognized the cumulative effect of initially applying the standard as an
adjustment to the opening balance of retained earnings while prior period
amounts are not adjusted and continue to be reported in accordance with Grid
Dynamics' legacy accounting under ASC Topic 605. The implementation of the new
standard did not materially affect our consolidated financial statements as
discussed further in Note 2 to Grid Dynamics' consolidated financial statements.
