 $281M$278MFY21FY20$1MFY20$14MFY22$2MFY21$379MFY22To Our Stockholders,

SigmaTron International, Inc. (SII) proudly reports that  
fiscal year 2022 (FY22) was a banner year with record 
financial results for the Company. With commitment forged 
at every level of the organization, our talented people 
applied our long-held operating principles to achieve this

chain, and geopolitical uncertainties that affected all 
electronic manufacturing services (EMS).

From this year’s rigorous environment, SII served a 
highest ever number of finished products and technically  
sophisticated customer programs, and made many a  
foray into exciting new industrial markets: clean energy, 
industrial internet of things (IIoT), safety sensors, and  
pet technology (“pet tech”). 

SII’S RECORD FY22 FINANCIAL RESULTS 
For FY22, revenues increased to $379 million from $278 
million in the prior fiscal year; net income increased to $9.9 
million in FY22 compared with $1.5 million in FY21. Basic 
and diluted earnings per share (EPS) for the fiscal year 
were $2.04 and $1.92, respectively, compared to basic and 
diluted EPS of $0.36 each in FY21. These year-end results 
built upon positive trends that emerged in Q4 FY21 and 
accelerated throughout FY22.

OUR Q3 ACQUISITION OF WAGZ INC. 
SII acquired Wagz Inc. (“Wagz”), a pet tech company, as 
a wholly-owned subsidiary on December 31, 2021. FY22 
includes four months of operating results for Wagz which, 
as an emerging company, is continuing steps toward 
profitability. Following completion of the Wagz acquisition, 
the Company’s number of shares increased by 1.6 million. 

An innovator in the pet tech market, Wagz focuses on 
modernizing pet containment with its patented product 
array. Our combined companies drive synergies from  
Wagz’ expert, innovative pet tech products from which  
flow dedicated EMS revenues to SII. Longer-term, Wagz’ 
internet of things (IoT) infrastructure—when combined  
with SII’s total EMS solution—is expected to drive other 
income potential from industrial and consumer customers 
who require manufacturing expertise for the latest IoT  
and Internet 3.0-enhanced products. 

FY22 LEADERSHIP ANNOUNCEMENTS: 
BUILDING OUR FUTURE
Amid significant growth and continuity in our commitment 
toward next generation EMS, SII made leadership  
announcements in FY22.

Following over 30 years of dedicated service to the 
Company, most recently as CFO, Linda K. Frauendorfer 
announced her retirement in Q2, while maintaining her 
role as a SII Board of Directors member. Her replacement, 
James J. Reiman, CFO, was announced concurrently.

In Q2, James E. Barnes, Executive Vice President and an 
18-year Company veteran, was promoted to President of SII 
to lead our traditional EMS business. Also, in Q3 post-Wagz 
acquisition and to keep pace with growth and expansion, 
Gary R. Fairhead was named as Chairman of the Board of 
Wagz Inc., while continuing as CEO and Chairman of the 
Board of SII. Wagz founder, Terry B. Anderton, remains the 
subsidiary’s CEO and President. 

SII MANAGES INDUSTRYWIDE  
CHALLENGES IN FY22 
With operating resilience, SII mitigated no fewer than four 
industrywide challenges.

■  Supply Chain Constraints – Demand, primarily in the 
semiconductor segment of the electronic component  
marketplace, continued to significantly exceed supply, 
creating pricing and availability issues. 

■  The U.S. Economy – In FY22, the U.S. economy grew 
moderately as COVID-19 cases declined overall but was 
offset by the GDP’s sharp contraction. By Q3, inflation 
rose by +1.5% to 7.9%—a 40-year high. By Q4, the Federal 
Reserve tightened its sell-off with U.S. stimulus relief 
funding expected to drive unknown outcomes well into 
FY23. For this, SII plans to manage any volatility or  
risks posed to our customers and business.  

■  Geopolitical Events – Certain global business disruptions 
followed Russia’s invasion of Ukraine and resulting sanctions. 
Currently, our main concerns are the impacts of war on  
our supply chain, namely neon and other noble gases 
essential to semiconductors, and other raw materials such  
as Russian-produced palladium.

■  COVID-19 and Variants – SII continued essential business 
status, complied with all local guidelines for our operations, 
and addressed global pandemic hotspots. In FY22, SII 
China faced its worst COVID-19 outbreak in two years 
with intensified lockdowns in multiple cities, especially 
Shanghai, a global transportation hub. In Q2 FY22, Asia’s 
lockdowns included SII Vietnam. Then in Q3, SII Mexico 
saw a temporary reduction in its operations.   

Going forward, should any of these industry factors persist, 
SII will respond accordingly.

The Wagz acquisition enables SII to take advantage  
of the entire margin stream flowing from its pet  
tech hardware sales. As an IoT and Internet 3.0 
product, these sales generate predictable, recurring 
revenue. Also, SII’s manufacturing footprint in four 
countries expedites Wagz time-to-market and aligns 
international sales opportunities. In parallel with  
their Wagz counterparts, SII’s decades-experienced  
engineering team helps optimize next-level design 
for manufacturing and test including RF products. 
SII’s global, supply chain systems support every  
aspect of Wagz business. Net/net, SII and Wagz

SIGMATRON UNITED STATES
In FY22, our U.S. locations in our Elk Grove Village, Illinois 
(EGV) headquarters and manufacturing site and our  
West Coast operations in Union City, California (UC), 
provided world-class design service, rapid prototyping, 
and complete-build manufacturing through fulfillment.

Building on prior years’ goals, EGV logged noteworthy 
customer gains: a deepened foray into industrial; clean  
energy EMS for solar and wind turbine pitch energy 
modules; and medium-to-higher volume assemblies for 
agriculture equipment. With FY22’s growth trajectory 
reported in these markets comes positive implications  
for SII in the near term. The division drove process  
efficiencies this year with expansion of its Tango MES 
system and several capital investments. 

For FY22, UC logged a significantly increased customer 
mix and volume across markets, but with a further lean into 
industrial and medical/life sciences. For one, UC gained 
a leading IIoT and global, semiconductor chip producer, 
growing it from initial consignment prototyping to full, 
turnkey production EMS. For its numerous divisions, UC 
led DFx and developed custom in-circuit tests (ICT)— 
each monitored remotely via the internet.

SIGMATRON MEXICO
In FY22, SII’s three manufacturing locations in Acuña, 
Chihuahua and Tijuana, Mexico, continue over three

onboarding and quickly scaling new high-to-low production 
volumes and a mix of models, regardless of complexity. 
Mexico continues complete product build EMS including 
customized lots of packaged products shipped on  
schedule to varied third-party locations. 

With an excellent transport corridor and mature customs  
infrastructure, the region saw continued strength  
in customer business amid FY22’s reshoring trends.  
As SII Mexico’s programs deliver close to their point 
of consumption, added benefits flow from our critically 
aligned time zones and work schedules.

The region faced the same industrywide issues as other 
divisions, but SII’s full suite of proprietary tools and our 
efficient Supply Chain processes minimized production 
impacts, with premium costs paid as warranted. 

In FY22, Mexico continues its valued full-service programs 
in OEM appliances, but saw expansion in equally desirable 
Industrial EMS: gaming, clean energy, and agricultural 
and commercial food equipment. In response, the region 
expanded its senior managers and engineering teams 
and honed its Lean Six Sigma process efficiency training 
to optimum time, materials, manufacturing, and packaging 
capacities. Engineering developed customized tests to 
support multiple, customer-driven product configurations, 
shipping them to individual global facilities. These 
customers gain standardization benefits, along with our 
worldwide purchasing power. 

The region increased its certification portfolio with  
U.K.’s Intertek product listing required to manufacture 
industrial (ballast) lighting. Also, a third location in  
Mexico achieved IATF 16949:2016 automotive systems 
compliance certification.

Ahead, as of Q4 FY22, Mexico’s customer program 
demands were steadily building, which bodes well for 
continued revenue growth in FY23 and beyond. 

SIGMATRON ASIA
Beginning in Q2 FY22, Asia’s expanded lockdowns brought 
challenges to its domestic economy and proffered risk to 
already strained supply chains. Amid this scenario, Asia 
leveraged SII’s global strengths and resiliency. This includes 
our Supply Chain teams who mitigated materials delays with 
spot-sourced goods and increased “safety stock,” supported 
by flows of working capital from SII Corporate. Also, SII saw 
certain air freight costs double, with a 500% increase  
in export container costs in just 18 months.

In Asia, program managers’ personal and timely communications 
among customers and suppliers succeeded in meeting 
material requirements to maintain production. Adaptively, 
certain customers saw advantages from components 
sourced in SII Asia while flexibly availing of N.A.’s  
manufacturing footprint.

personalized EMS—one that vitally supports customers 
across the entire lifespan of their programs.

In summary for FY22, SII’s operating philosophy,   
technologically advantaged services, and complete 
manufacturing for a targeted customer mix netted a  
banner year of accomplishments despite the myriad of 
economic and geopolitical events faced by all EMS. 

For this important benchmark, we acknowledge the  
ongoing support and commitment of our Board of 
Directors, management, employees, and supply chain 
professionals around the world. 

IN MEMORIAM 
On behalf of our entire Company, as we express gratitude 
to these stakeholders, we also commemorate the loss 
in Q4 FY22 of our Corporate Counsel Henry (“Hank”) 
J. Underwood. Hank was a consummate attorney who 
worked with countless companies, including SigmaTron. 
Across nearly four decades, we benefited from Hank’s 
legal expertise, respected his business acumen, and 
valued his support and friendship.

CONTINUING OUR STRENGTHS AND  
RESILIENCY IN FY23
Ahead, SII is well poised to monetize new business  
opportunities and capture our share of our booming  
market potential—especially for increasingly complex 
engineering and in performance requirements including 
IoT-enhanced EMS. In this rigorous business environment, 
we plan to recommit to further transformation as a  
company—steadily moving toward a more resilient, 
innovative, and intelligent program mix.

Given signals of ramping market demand, SII expects in 
FY23 to continue a growth path in the five countries where 
we operate. We expect opportunities to remain strong for 
both our traditional EMS and pet tech businesses—each 
aligned to deliver increased stockholder value. 

Sincerely,

Gary R. Fairhead,  
Chief Executive Officer
