Chairman’s statement

Wolica, Poland

Chairman’s statement

Dear Shareholders, 

At  the  end  of  2023,  we  achieved  a  key  milestone  in  the 
development  of  our  Group,  with  the  proposed  acquisition 
of  CRH’s  European  lime  assets.  The  first  and  largest  of 
three phases of this transaction completed post period end, 
in  January  2024,  and  we  are  now  positioned  to  become 
a  leading  operator  in  these  markets  across  Europe.  This 
strategic  move,  a  long-held  ambition  cultivated  through 
careful  assembly  of  the  right  assets  in  Northern  Europe, 
brings transformational scale, market position and product 
offering as we evolve into a leading lime entity.  

This  strategic  advancement  was 
realised  amidst 
challenging market conditions both in equity markets and 
across various sectors and regions, yet we maintained our 
core  business's  record  of  continuous  improvement,  with 
another  year  of  strong  performance.  This  report  offers 
deeper insights and context as we gear up for yet another 
year of substantial progress.

OVERVIEW

I  am  very  pleased  to  report  another  solid  financial 
performance  for  the  year.  Despite  a  challenging  market, 
we  achieved  a  2%  LFL  increase  in  revenues  to  £580m, 
while  managing  a  4%  LFL  decrease  in  volumes.  This 
performance  underscores  the  robust  and  diverse  nature 
of our Group, adept at sustaining earnings growth even in 
subdued markets. 

15

We  also  enhanced  our  underlying  profitability,  with  a  10% 
LFL  increase  in  underlying  EBITDA,  and  a  modest  yet 
positive improvement in underlying EPS to 8.12p. This was 
achieved  amidst  a  significant  YoY  increase  in  financing 
costs  and  the  effective  absorption  of  the  dilutive  impact 
from the February 2023 fundraising. 

"Our teams have  
demonstrated exceptional 
focus and efficiency, leading 
to operational improvements 
across the board and a return  
to historical margin trends."

David Barrett 
Executive Chairman

These  efficiency 
improvements  have  been  primarily 
operational and have led to significant net cost reductions 
across  the  Group.  Commercial  initiatives,  selling  product 
in new markets, or new products in old markets have also 
helped deliver these results.

Barrett

CHAIRMAN

STRATEGIC REPORT

Our  year  was  not  just  about  financial  gains.  We  made 
in  our  environmental,  social,  and 
significant  strides 
governance 
initiatives.  Our  safety  standards 
(ESG) 
have  improved  further  due  to  a  new  group-wide  safety 
management approach. Environmentally, we have made a 
significant leap by operating one of Europe’s largest carbon 
capture  systems  in  Sweden.  In  respect  of  Governance, 
we are actively pursuing the addition of two independent 
board  members  and  the  refinement  of  our  policies  and 
procedures strengthens our corporate structure.

LIME AND LIMESTONE

The  CRH  Lime  Acquisitions,  announced  in  November 
2023, stand as a transformative milestone for the Group. 
These acquisitions not only elevate our operations in the 
sector, but also align with our ambition for compounding 
growth and market leadership. Lime and limestone, being 
essential  to  modern  life  and  industry,  place  us  at  the 
forefront  of  a  market  critical  to  the  ongoing  economic 
transition towards sustainability.

Lime  and  limestone  are  less  well  understood  as  critical 
minerals for modern life. They are however, both key, and 
will  continue  to  be.  Lime  is  sometimes  described  as  by 
far  the  cheapest  alkali  available,  and  alkali  are  a  group 
of  chemical  compounds  without  which  a  whole  host  of 
industrial  processes  simply  cannot  run.  This  is  what 
makes these minerals so exciting to us as a Group. 

OUTLOOK

As we enter FY24, we have several important areas of focus 
including  the  completion  of  the  remaining  transactions 
from CRH and seamlessly integrating these assets. Once 
integrated  we  will  turn  our  attention  to  delivering  the 
previously outlined synergies, enhancing cash flows, and 
reducing  leverage,  thereby  setting  a  strong  foundation 
for  further  growth,  with  a  strategic  focus  on  lime  and 
limestone. 

The trading backdrop in the early months of 2024 remains 
similar to 2023, characterised by variability and challenges, 
conditions  which  our  diversified  market  exposure  is  well 
set up to effectively address. The European construction 
sector  continues  to  face  challenges,  in  the  residential 
segments,  whilst  ongoing  infrastructure  investment  is 
expected  to  support  ongoing  project  activity.  Industrial 
demand  will  vary  by  sector,  influenced  by  both  local  and 
global trends. In particular paper and pulp is having a better 
year,  while  steel  production  benefits  from  disruptions  in 
other regions.  

Overall, however, we remain optimistic on the outlook for 
the year with respect to potentially improving demand for 
newbuild housing as expected interest rate cuts improve 
the wider construction climate.  The likely reversal should 
have  further  spill-over  effects  in  other  areas  of  the 
economy benefitting our end markets in general.  

In  closing,  the  past  year  has  been  a  testament  to  our 
resilience  and  strategic  foresight.  As  we  move  forward, 
we  remain  committed  to  facing  challenges  head-on  and 
capitalising on opportunities for growth and development.

Thank you for your continued trust and support.

Nordkalk limestone

CEO’s strategic report

Dear Shareholders,

In  2016,  we  launched  SigmaRoc  with  the  ambition  to 
operate a portfolio of high-quality assets across Northern 
Europe which would give us an advantageous competitive 
position  thanks  to  their  market  position,  barriers  to  entry, 
margin  and  improvement  potential  and  potential  links  to 
larger  economic  players.  All  of  these  features  are  clearly 
evident in what we now very simply describe as a leading 
European lime and limestone business. 

Lime and limestone are a unique group of products, critical 
to  modern  life  and  essential  to  a  more  sustainable  world. 
Building  a  leading  position  in  this  sector  is  not  easy  and 
has  been  the  long-term  ambition  of  our  group,  initially 
through  our  acquisitions  of  CDH  in  2019  and  Nordkalk  in 
2021. Whilst market and operating conditions in both 2022 
and  2023  became  increasingly  challenging,  leading  many 
competitors  to  pause  their  strategic  growth  ambition,  we 
continued to integrate, grow and optimise our businesses 
with the same agility and focus that has been the hallmark 
of  the  Group.  By  retaining  focus  on  our  goals,  we  were 
able  to  execute  the  transformational  strategic  step  in  our 
evolution this year, through the acquisition of CRH’s asset 
base  and  successfully  position  ourselves  as  a  leader  in 
limestone  and  lime  across  Northern  Europe.  This  pivotal 
evolution has not only brought strategic alignment across 
our  operations  but  also  paved  the  way  for  sustainable 
growth and enhanced shareholder value.

19

The  journey  to  this  point  has  been  intricate  and  required 
a  series  of  calculated  assumptions  and  strategic  steps, 
executed with precision and timeliness. The support from 
our  shareholders  and  the  relentless  commitment  of  our 
team were instrumental in this journey. Their contributions 
have been the cornerstone in establishing SigmaRoc as a 
key  player  in  the  European  lime  industry,  a  sector  vital  to 
both construction and industrial applications.

"Throughout the year, we 
successfully repositioned 
ourselves as a leader in limestone 
and lime across Northern Europe. 
This pivotal transformation 
has not only brought strategic 
alignment to our operations 
but also paved the way for 
sustainable growth and enhanced 
shareholder value."

CEO’s strategic report

This  statement  aims  to  provide  additional  context  on  the 
year that just closed, the steps taken, and how these steps 
now set the Group up for chapter two of its journey. We are 
now poised to focus on integrating our diverse operations 
into  a  synergistic  whole,  a  compounding  value  creator,  a 
driver of innovation, a leader in the sector, and hopefully the 
envy of the industrial minerals space.

FINANCIAL PERFORMANCE 

The  Group  again  delivered  a  strong  performance  against 
very challenging market conditions in 2023, a testament to 
the diversification and quality of the business, as well as the 
skill in execution  of our team. Group revenue increased to 
£580m, a 2% LFL increase. Underlying EBITDA increased to 
£117m, an increase of 10% LFL. 

Underlying profit after tax increased to £58.8m, translating 
into  underlying  EPS  of  8.12p,  representing  a  1%  increase 
YoY.  This  evolution  is  very  pleasing  as  the  senior  debt 
finance costs more than doubled between 2022 and 2023, 
reflecting  rising  interest  rates.  Tax  expense  increased 
also,  from  15%  to  17%  of  profit  before  tax,  as  some  carry 
forward  losses  were  used  up  in  prior  periods.  The  ability 
of  the  Group  to  deliver  another  year  of  underlying  EPS 
growth  is  an  enormous  testament  to  the  hard  work  of  so 
many, in particular those seldomly mentioned in our annual 
report,  our  machine  and  plant  operators,  quarry  staff  and 
sales representatives who all look for ideas to improve the 
performance of the Group.

Considering this performance on a more granular level, the 
Group  performed  particularly  well  given  some  of  the  local 
trading  conditions.  Overall  volumes  were  down,  as  was 
to  be  expected,  but  by  only  4%  LFL,  a  modest  drop  when 
considering  an  average  European  construction  output 
slowdown of 1.7% with 1.6% in the UK.1 The largest impact 
on volumes was therefore within the construction segment, 
particularly  newbuild  housing,  where  much  action  was 
taken early in the year. 

in 

line  with  our 
Industrial  performance  was  overall 
expectations,  for  a  year  without  volume  growth  on  the 
back of overstocking in the paper segment, and a reduction 
in  demand  for  some  chemical  applications.  These  lower 
volumes  were  compensated  for  by  robust  continued 
demand in steel, environmental and infrastructure projects.

Considering  these  trends  on  a  regional  basis,  our  North 
West  Region,  comprising  mostly  construction  materials 
businesses  including  more  commodity-like  products,  had 
several  challenging  months  to  endure  as  they  actively 
shifted  focus  from  residential  to  infrastructure  projects. 
Much progress was made to upscale the precast products. 
The  integrated  businesses  in  Wales  and  the  Channel 
Islands  delivered  a  strong  year,  despite  several  contractor 
bankruptcies in Jersey created disruption in this market. As 
a result, the North West Region recorded a LFL decrease in 
revenues of 1%, against a LFL decline in volumes of 8% and 
LFL underlying EBITDA improvement of 1%. 

The West Region also delivered a solid performance across 
its two platforms, Dimension Stone and Benelux. Initiatives 
taken in 2022, commercially and within production, helped 

1.Global consulting firm

Dimension Stone trade successfully through a challenging 
market,  assisted  by  additional  infrastructure  work  and 
overseas  sales.  The  aggregates  and  concrete  businesses 
both  had  good  years,  despite  increased  monthly  volume 
volatility.  West  Region  volumes  decreased  by  8%  LFL, 
delivering  overall  revenues  of  €114m,  a  LFL  decrease  of 
7%.  In  spite  of  the  difficult  trading  conditions,  the  West 
Region  was  able  effectively  to  manage  its  cost  base  and 
increase underlying EBITDA by 15% LFL, achieving a 473bps 
improvement  in  underlying  EBITDA  margin  in  the  process. 
The  new  businesses  in  the  Limburg  Region  and  on  the 
southern border of Belgium performed well, delivering more 
than expected in their first partial year of ownership.

Our  North  East  Region  had  a  great  year  delivering  on  all 
strategic and financial priorities. The restructure announced 
at the end of 2022 helped deliver a more agile organisation, 
able to capture more value via commercial and operational 
initiatives.  Revenues 
increased  to  €390m,  a  3%  LFL 
increase, on volumes down 3% LFL, driven mainly by weaker 
residential  construction  demand  in  the  Nordics  which  has 
relatively low impact on profitability. The Lime, Poland and 
the  Baltic  businesses  performed  strongly,  translating  into 
a  12%  LFL  increase  in  underlying  EBITDA  and  a  179bps 
improvement in underlying EBITDA margin.

STRATEGIC DEVELOPMENT

2023  marked  an  exceptionally  dynamic  year 
in  our 
Group’s  history.  At  the  end  of  2022  we  had  identified 
several  acquisition  and 
investment  opportunities  that 
were  available  at  depressed  valuations,  due  to  macro-
economic uncertainty. This pipeline of bolt-on acquisitions 
consolidated  our  positions  in  Sweden,  Finland,  the  Baltic 
states,  Benelux and the UK, expanding our Group in terms 
of  geography  and  product  range  in  a  year  where  volume 
growth was likely to be extremely challenging.

As we embarked on integrating these bolt-on acquisitions, 
our focus shifted to an opportunity that has been a long-held 
ambition of the Group – the acquisition of CRH’s lime and 
industrial  limestone  assets.  These  very  significant  assets, 
known for their operational efficiency and value, presented a 
complex acquisition proposition, especially in a transaction 
climate that appeared less favourable.

Notwithstanding  the  backdrop,  our  evaluation  of  the 
transaction was very clear and came from two perspectives: 
firstly,  its  financial  viability,  considering  immediate  and 
long-term  earnings  growth  and  our  ability  to  achieve  and 
maintain  target  ROIC  levels;  and  secondly,  the  strategic 
value in elevating our status, not merely as a participant in 
the lime and limestone sector, but as a principal producer of 
these essential materials in Northern Europe.

What  followed  were  months  of  work  by  a  small  but 
dedicated team to deliver a transaction which if completed 
in  full,  would  see  our  Group  double  in  size  and  establish 
itself  as  Europe’s  second  largest  producer  by  volume  of  a 
critical industrial and construction mineral. The project was 
ambitious  and  extremely  challenging  given  its  scale  and 
structure.

It required a significant scale up in debt facilities which our 

STRATEGIC REPORTSIGMAROC ANNUAL REPORT 2023two  main  banks,  Santander  and  BNPP,  fully  underwrote. 
We  further  relied  on  equity  investment  from  existing  and 
new  shareholders  to  fund  the  acquisitions.  Despite  the 
complexities, with the critical support from our shareholders 
we  were  able  to  finalise  the  transformative  transaction  by 
the end of November 2023. 

The acquisitions do more than just amplify our size in the 
lime  sector.  First,  they  clarify  and  accelerate  our  strategic 
direction,  affirming  our  central  commitment  to  the  lime 
and  limestone  sector.  Secondly,  they  bring  us  to  a  scale 
where  concurrent  objectives  of  compounding  growth, 
share buybacks, dividend distributions, and debt reduction 
become  achievable.  Lastly,  through  geographic  footprint 
and product offering, it transforms SigmaRoc into a unique 
asset  backed  industrial  minerals  group  with  much  further 
potential.

SAFETY

The  Group  has  made  significant  progress 
in  safety 
throughout 2023, with our drive for continuous improvement 
prompting a fresh perspective on safety practices. Although 
reporting  via  our  HighVizz  application  was  already 
commendable, the implementation of learnings across the 
Group needed improvement.

In  response,  our  board  safety  committee  introduced  two 
fundamental  changes.  First,  we  launched  a  Group-wide 
supervisor  training  programme  to  ensure  that  supervisors 
are effectively fulfilling their roles. This training highlighted 
that, in many cases, individuals designated as supervisors 
were  not  fully  performing  their  duties,  leaving  critical 
supervisory  roles  effectively  unmanned.  As  a  result, 
unsafe behaviours or key learnings at Group level were not 
consistently reaching operators.

The  second  major  change  was  the  initiation  of  a  safety 
audit  programme.  Similar  in  concept  to  a  financial  audit,  
the safety team of the Group, with a Group-wide mandate, 
now conducts audits at all sites to assess both the accuracy 
of  safety  documentation  and  the  actual  safety  practices  
on the ground.

These audits are designed to drive continuous improvement 
in  our  operations.  172  audits  were  conducted  this  year  by 
Clint White, our HSE&P Director. An incredible feat reflecting 
our  unwavering  commitment  to  ensuring  the  highest 
standards of safety across all operations. A comprehensive 
review of the progress we have made can be found in the 
ESG section of this report on page 92.

ENVIRONMENTAL AND SOCIAL

Alongside  safety  we  made  good  progress  in  a  number  of 
other  facets  of  our  ESG  strategy  in  2023.  To  document 
progress  clearly,  we  have  now  included  a  dedicated  ESG 
section  in  this  report,  starting  on  page  92.  Of  the  many 
initiatives detailed in the ESG report, there are four projects 
of which we are especially proud.

First,  we  believe  we  are  the  first  kiln  operation  in  Europe 
with  a  fully  functioning  carbon  capture  facility,  capable 
of  capturing  CO2  at  scale.  The  installation  has  been  fully 
commissioned  and  is  now  capturing  CO2  to  calibrate  the 
second stage of the CCUS process – either utilisation (U), 

21

or sequestration (S). Progress is being made in both areas, 
with  the  help  of  additional  testing  facilities  to  ensure  the 
quality  and  consistency  of  the  captured  CO2  for  effective 
use in either U or S scenarios. 

The second project is the launch of a full-scale aggregates 
recycling  installation  in  North  Wales,  which  now  treats 
and  recycles  350kt  tonnes  of  waste  aggregates  per  year. 
This  initiative  will  eventually  liberate  c.5m  tonnes  of  virgin 
aggregate previously trapped beneath waste piles deemed 
of  insufficient  quality  for  recycling.  This  complements 
our  recycling  activities  in  Finland,  Sweden,  Belgium  and 
the  Channel  Islands,  where  we  are  processing  returned 
concrete, demolition waste and waste aggregates.

The third project focuses on utilising 100% of the material 
extracted  from  our  dimension  stone  quarries.  Previously, 
stone  not  suitable  for  high-quality  slabs  or  tiles  was  used 
for security bunds or construction aggregate – neither high 
in  value  nor  value-add.  Throughout  the  year,  our  teams  in 
Belgium  have  explored  various  high-value  applications  for 
this stone, significantly enhancing its potential.

Lastly,  we  have  continued  our  efforts  to  clean  our  energy 
sources,  both  in  terms  of  combustibles  and  electricity. 
Significant  progress  detailed  in  the  ESG  section  on  page 
131 includes applications for wind turbines to supplement 
our solar arrays and increase clean energy usage at various 
production  sites.  Additionally,  we  are  transitioning  to 
biofuels for running our kilns, having already achieved a full 
week of operation solely on biofuels – a first in the industry.

With  respect  to  social  targets  we  have  made  a  leap 
forward  as  well,  delivering  over  22,000  hours  of  learning 
and  development,  as  well  as  promoting  diversity  across 
the  group  with  42%  of  non-operational  positions  being 
held  by  women.  At  a  local  level  our  business  continues  to 
work  closely  with  our  communities,  donating  time  and 
materials to community projects as well as land and water 
for community use.

Overall, the progress in 2023 has been significant, paralleled 
by our active engagement in financial and growth objectives. 
More developments are expected in the future.

STRATEGIC REPORT

CEO’s strategic report

INNOVATION

The fourth pillar of our 4i operational model, innovation, 
has  seen  notable  advancement,  extending  beyond  our 
ESG-related  programmes.  This  year  we  have  made 
significant progress in our product range and innovation 
investment, with three projects particularly standing out.

First, we have made considerable further progress with 
our Greenbloc range. This product line is now incorporated 
in almost all of our concrete products, available in three 
distinct performance levels. These levels provide a range 
of embodied CO2 reductions from 50% to 90%. Looking 
ahead,  we  aim  to  surpass  the  100%  mark,  positioning 
ourselves as pioneers in producing large-scale negative 
carbon concrete products.

In our quest for innovation, we have initiated a scheme to 
fund  external  technologies  that  can  make  our  products 
more  competitive,  advanced  and/or  sustainable. 
HighVizz was an early success within this initiative and 
building on this, we have now formed a partnership with 
Mevo.

Mevo is a revolutionary new technology for the grinding 
and  blending  of  non-cementitious  minerals,  imparting 
certain  binding  properties  to  the  materials.  We  have 
supported  Mevo  in  raising  £15m  in  venture  funding 
and  have  assisted  in  the  construction  of  its  first  large-
scale plant. Once operational, we anticipate that Mevo’s 
technology  will  be  at  the  forefront  of  decarbonising  all 
our concrete products.

POST PERIOD ANNOUNCEMENTS 

On  4  January  2024  the  Group  successfully  completed 
the  first  of  three  proposed  CRH  Lime  acquisitions,  and 
in conjunction with CRH Deal 1 completed admission of 
the  Group’s  enlarged  share  capital  with  a  £200m  gross 
equity fundraise and new €875m senior finance facility.

On  1  March  2024  the  Group  issued  notice  of  exercise 
of  the  call  option  to  acquire  CRH’s  UK  lime  operations 
for a total consideration of €155m, with the transaction 
expected to complete by the end of March 2024.

OUTLOOK

SigmaRoc’s  impressive  performance  in  2023,  reflected 
in our robust financial results, underscores the inherent 
strength  and  quality  of  our  assets  and  operations. 
Since  January  2024,  we  have  welcomed  several  new 
businesses into our Group, and this expansion is set to 
continue as we acquire the remainder of CRH’s European 
lime businesses in a planned phased approach. Each of 
these  acquisitions  represents  high-quality  assets  with 
strong  market  positions,  reinforcing  our  confidence 
in  the  sustained  performance  of  not  only  our  existing 
operations  but  also  those  of  the  recently  integrated 
businesses.

This  report  was  approved  by  the  Board  on  17  March

Bolt-on acquisitions during 2023

27

In  February  2023,  the  Group  raised  £30m  of  equity  to 
accelerate  execution  on  a  pipeline  of  acquisitions  across 
the  Group,  which  had  been  assembled  over  the  previous 
12 months. The acquisitions were made on an average EV/
EBITDA multiple of 3.9 times and are expected to contribute 
an additional c. £8m of annualised EBITDA. A summary of 
each of the acquisitions is as follows:

GOIJENS, BELGIUM

The acquisition of Goijens, a leading supplier of ready-mixed 
concrete and recycling solutions, was closed at an effective 
multiple of 5 times recurring average EBITDA for the years 
2020  to  2022.  As  with  other  acquisitions  the  Group  has 
made, we expect synergies and operational improvements 
to  reduce  the  effective  multiple  paid  and  Goijens  traded 
ahead  of  the  acquired  EBITDA  in  its  first  months  of 
ownership within the Group.

JUUAN DOLOMITIK, FINLAND

The  Group  completed  the  acquisition  of  Juuan  Dolomitik 
for  an  effective  multiple  of  2.6  times  recurring  average 
EBITDA  for  the  years  2020  to  2022,  pre-synergies  and 
operational  improvements.  JD  is  a  specialist  supplier  of 
high-quality  dolomitic  limestone,  used  in  the  agricultural 
and environmental sectors to improve regulation of soil pH 
and water retention. JD’s operations are located close to the 
Group’s existing Finnish business and represent a valuable 
extension into dolomitic limestone. JD adds approximately 
1.5m  tonnes  of  reserves,  equating  to  roughly  30  years  of 
operating life, and €1.5m of revenues to the Group.

RETAINING, UK

In April 2023 the Group closed the acquisition of Retaining, a 
leading manufacturer of specialty retaining wall systems, for 
an effective multiple of 2.9 times recurring average EBITDA 
for the years 2020 to 2022, before expected synergies and 
operational improvements. This business fits well with the 
PPG precast platform, both expanding its range of walling 
solutions, which already includes the patented Alfabloc, as 
well as extending PPG’s reach into the north of the UK.

ST INVESTICIJA, LITHUANIA

In  July  2023  the  Group  acquired  aggregates  supplier  
ST  Investicija  and  its  subsidiaries,  which  operate  three 
quarries in Lithuania. The acquisition materially strengthens 
the aggregates business of our Baltics platform, bolstering 
the  mineral  position  and  quarrying  assets  of  the  Group  
in this region.

BJÖRKA MINERAL, SWEDEN

In  August  2023  the  Group  acquired  Björka  Mineral,  a 
subsidiary  of  Swiss  industrials  materials  group  Omya,  for 
an  undisclosed  sum.  Björka  Mineral  is  a  leading  supplier 
of high-grade limestone and dolomite powders. It operates 
three  quarries  that  are  synergistic  to  the  Group’s  existing 
operations in Sweden.

BETONS, BELGIUM/FRANCE BORDER

In September 2023 the Group formed Betons and acquired 
four concrete plants located in Northern France from leading 
limestone  producer  Groupe  CB.  The  concrete  plants  were 
acquired  for  an  initial  consideration  of  3.5  times  recurring 
EBITDA for the year 2022.

 CRH Deal 3

Consists of the Polish lime operations of CRH for a total 
consideration  of  €100m,  to  be  funded  from  deferred 
consideration. Deal 3 is subject to a call option, whereby 
SigmaRoc  has  been  granted  the  right  (but  not  the 
obligation) to acquire the Polish lime operations of CRH.

The  Polish  lime  operations  are  also  integrated  within 
other CRH businesses and similarly need to be carved 
out into a standalone entity before they can be acquired. 
Deal  3  is  anticipated  to  complete  toward  the  end  of 
3Q24 and is subject to anti-trust filings.

On  an  FY22  pro-forma  basis  the  enlarged  group,  being 
SigmaRoc  plus  the  Acquisitions,  would  have  reported  the 
following key metrics:

underlying revenue in excess of £1b

underlying EBITDA of £211m

• 
• 
•  mineral reserves of c. 2.7b tonnes
• 
• 

operations in 14 countries 

over 3k employees

Strategically  the  Acquisitions  represent  an  opportunity 
to  become  one  of  Europe’s  leaders  in  lime,  combining 
high  quality  businesses  and  complementary  footprints, 
positioning the Group as either the number one or number 
two participant in all its key lime markets.

Lime  and  limestone  are  key  resources  in  the  transition 
to  a  more  sustainable  economy  and  lime  products  are 
natural  carbon  absorbers.  New  applications  for  lime  and 
limestone  products  as  part  of  a  drive  for  sustainability 
include  the  production  and  recycling  of  lithium  batteries 
as part of increasing electrification, the decarbonisation of 
construction including through substitution of cementitious 
material,  and  new  building  materials,  and  environmental 
applications  including  lake  liming,  air  pollution  control  and 
direct air capture.

Furthermore, the Acquisitions are aligned with the Group’s 
ESG  and  net-zero  ambitions,  positioning 
the  Group  
to be part of CCUS hubs, and giving the Group a strategic 
role  in  the  decarbonisation  of  key  industries  such  as  
steel and chemicals.

CRH Lime Acquisitions

On  22  November  2023,  the  Company  announced  the 
conditional  and 
transformational  acquisition  of  a 
comprehensive  portfolio  of  European  lime  and  industrial 
limestone  assets  from  CRH,  alongside  a  £200m  equity 
fundraising and new €875m debt facility.

The  acquisitions  are  independent  of  each  other,  but  on  a 
combined  basis  represent  a  total  consideration  of  €1bn, 
with €825m initial and €175 million deferred consideration. 
The acquisitions are structured as follows (with Deal 1, Deal 
2 and Deal 3 collectively representing the ‘Acquisitions’):

•  CRH Deal 1

Comprises German, Czech and Irish lime and industrial 
limestone businesses for a total consideration of €745m, 
subject to customary purchase price adjustments. The 
consideration  satisfied  by  a  combination  of  €230m 
from  gross  equity  proceeds,  €350m  drawdown  from 
the new debt facility and €75m deferred consideration.

Due to its size, Deal 1 comprised a reverse takeover of 
the Company under the AIM Rules for Companies and 
was  therefore  conditional  on  Shareholder  approval, 
which  was  obtained  at  a  general  meeting  held  on  11 
December  2023.  Deal  1  has  been  completed  on  4 
January  2024,  bringing  to  the  Group  1  billion  tonnes 
of  reserves,  over  850  employees,  and  annualised 
revenues of over €350m. The addition of these assets 
transforms the scale of the Group’s industrial minerals 
business and is expected to unlock significant financial, 
operational and strategic benefits.

•  CRH Deal 2

Consists  of  the  UK  lime  operations  of  CRH  for  a  total 
consideration  of  €155m,  to  be  satisfied  entirely  by 
drawdown from the new debt facility. Deal 2 is subject

Aqualung carbon capture 
unit in Köping, Sweden

In  2023,  SigmaRoc  successfully  installed  and  commissioned  its  first  carbon  capture  unit  at 
Nordkalk’s site in Köping, Sweden. The fully scalable carbon capture system, utilising Aqualung’s 
innovative membrane technology, is the first-ever implementation of its kind in the industry.

The carbon capture system has been developed by Aqualung, 
a  leading  provider  of  membrane-based  carbon  capture  and 
separation technology, based in Norway.

Over  the  course  of  the  preceding  year,  SigmaRoc  reviewed 
an  array  of  technologies  including  amine  absorption,  solid 
absorption,  membrane  and  cryogenic.  The  Aqualung 
membrane  technology  was  considered  best  suited  for  the 
Group’s  operations  based  on  the  following  factors:  small 
footprint, low CapEx and operating costs, and a relatively low 
complexity and efficient solution. The system is modular and 
fully scalable, allowing SigmaRoc significant flexibility in the 
roll out of the solution.

The Aqualung module installed in Köping can capture up to 
25% of the process emissions emitted from a standard kiln 
and was initially designed as a ‘catch and release’ system to 
demonstrate the durability and efficiency of the membranes. 
The unit is able to capture CO2 with a purity of 96% through 
just  2  stages  and  has  since  been  connected  to  a  pilot 
purification module to simulate settings required to produce 
higher  purities  of  CO2  for  different  end  use  applications 

that  go  beyond  sequestration  requirements.  We  believe 
review of alternative application is required whilst European 
Governments and third parties develops legislation, policies 
and  sequestration  infrastructure  including  pipeline,  storage 
facilities  and  portside  facilities  to  allow  for  commercially 
available sequestration.

SigmaRoc  is  working  with  various  businesses  and  solution 
providers  with  regards  to  the  end  use  of  CO2,  including 
being  involved  with  the  NICE  (Norvik  Infrastructure  CCS 
East  Sweden)  project  to  explore  all  CO2  utilisation  and 
sequestration options. 

Nordkalk also secured part-funding from the Swedish Energy 
Agency  for  the  implementation  and  scaling  of  the  Köping 
carbon system with the intention to capitalise on the learning 
from the engineering, commissioning and operation phase of 
the initial module.

SigmaRoc will continue to update on the progress as well as 
roll-out plans to implement the technology in all of Nordkalk’s 
operating kilns by 2030.

"As a Group we are always on the lookout for interesting technologies 
that can help us advance our business and our operations. Aqualung 
is clearly that type of technology. Partnering with them to potentially 
decarbonise our operations well ahead of not just our timeline but 
probably the entire industry, is very exciting and the result of intense 
work across the Group, in particular at Nordkalk."

Materials Evolution (Mevo)

During the year, SigmaRoc entered a strategic partnership with Material Evolution, an advanced 
materials company producing low carbon cement from industrial waste streams, to develop a 
range of low carbon concrete products. 

Mevo has developed a process that produces an emission-
free  substitute  for  ready-mix  and  precast  concrete.  With 
the  cement  industry  currently  accounting  for  8%  of  global 
CO2  emissions,  there  is  growing  demand  for  reducing  its 
carbon footprint. Mevo’s innovative manufacturing process 
effectively  addresses  the  problem  of  high  CO2  emissions 

from conventional cement production by producing cement 
at ambient temperatures using various waste materials and 
feedstocks, thereby eliminating the reliance on fossil fuels. 

Trials  for  product  development  have  commenced  at  CCP, 
SigmaRoc’s largest precast concrete manufacturer.

"Our partnership with Mevo marks a significant step towards an 
emissions-free solution for ready-mix and precast concrete. Through 
our trials at CCP, we are confident that these innovative products will 
not only meet market demand but also pave the way to transforming 
the cement industry and driving sustainable innovation."

Greenbloc and environmental sustainability

CCP  Greenbloc  as  standard;  Through  2023  Greenbloc 
technology  has  made  significant  strides  in  sustainable 
development across the business, offering up to 50% carbon 
reduction on all standard blocks produced at CCP Building 
Products.  This  has  saved  over  6,000  tonnes  of  CO2  since 
its introduction and has been offered at no additional cost 
to the customer. CCP completed its expanded new ranges 
by introducing an additional premium range product, which 
sits between its standard 50% reduction product and ultra 
cement-free, and provides up to a 70% carbon reduction at 
a competitive price.

Poundfield  Cement-free;  Further  Greenbloc  cement-free 
development at Poundfield introduced a necessary flexible 
solution,  enabling  daily  production  and  the  ability  to  turn 
for  environmentally 
cement-free  concrete  on-and-off 
the  UK 
significant  bespoke  projects.  These 
Environmental  Agency’s  Canvey  Island  Sea  Defence  and 
Jimmy’s Farm Polar Bear Relocation projects, both of which 
achieved  over  80%  reduction  in  the  carbon  embodiment 
of  the  concrete  products.  As  a  result  of  these  initiatives, 
Poundfield  has  become  one  of  the  leading  UK  producers 
of  cement-free  pre-cast  concrete,  producing  more  wet-

include 

cast  cement-free  concrete  per  day  than  any  other  precast 
company,  and  underscoring  the  industry’s  shift  towards 
more sustainable practices. The resulting media focus has 
brought more cement-free projects to the business for 2024.

Greenbloc carbon-negative; A leap in innovation was gained 
through  the  production  of  a  carbon-negative-cement-free 
concrete  block,  which  boasted  a  115%  carbon  reduction 
and was created using Greenbloc cement-free technology, 
combined  with  carbon-negative  aggregate  produced  from 
waste  materials  and  captured  carbon.  The  block  showed 
all the same characteristics and performance as standard 
equivalent cement-based blocks and is expected to become 
part  of  an  extended  future  range  with  the  introduction  of 
Mevo at CCP in 2024.

Marshalls  collaborative  Greenbloc  –  MTech;  SigmaRoc 
has  produced  an  in-house  cement-free-carbon-negative 
concrete  with  patentable  opportunities,  in  collaboration 
with  Marshalls.  The  concrete  combines  carbon-negative 
materials  with  an  in-house  developed  cement-free  binder 
which  incorporates  upcycled  waste  lime  kiln  dust  from 
Nordkalk. The patent application will be submitted in 2024 
with expected opportunities for use in 2025.

Mega trend: Decarbonisation (of construction)

DECARBONISATION OF CONSTRUCTION

HOW WE ARE RESPONDING

Many countries across Europe have embraced 
ambitious goals and comprehensive strategies 
to transition towards low-carbon and sustainable 
pathways. Spearheading this movement, the 
European Commission launched the EU Green 
Deal in 2019, committing the bloc to achieving 
climate neutrality by 2050. This initiative sets out a 
roadmap for reducing greenhouse gas emissions, 
enhancing energy efficiency and fostering green 
innovation across all sectors of the economy. 
The transition to a net-zero economy in Europe is 
projected to require substantial investment, with 
estimates suggesting that approximately €350 
trillion will be needed in cumulative spending 
on physical assets globally over the next three 
decades, with a significant portion allocated 
within the next 10-15 years. This translates to 
an annual spending of €11.7 trillion, indicating a 
surge in demand for sustainable solutions across 
various industries as part of Europe's ambitious 
decarbonisation efforts.

The decarbonisation of the construction industry 
in Europe stands as a pivotal mega trend in 
the global sustainability transition, with lime 
and limestone emerging as crucial resources. 
These versatile materials play an important 
role in various eco-friendly applications, notably 
as substitute cementitious materials, where 
they significantly reduce carbon emissions 
associated with traditional cement production. 
Moreover, innovations such as hemp lime for 
building materials showcase the potential of 
integrating sustainable practices into construction, 
offering both insulation properties and reduced 
environmental impact. Additionally, the 
incorporation of hydrated lime into asphalt mixes 
not only enhances durability and performance but 
also contributes to reducing the carbon footprint 
of transportation infrastructure. As the industry 
continues to embrace new building materials 
and techniques, lime and limestone stand at the 
forefront of facilitating a greener, more sustainable 
future for construction in Europe and beyond.

HOW WE ARE RESPONDING

Lime plays a crucial role in the production and 
recycling of lithium-ion batteries, essential for 
powering electric vehicles and storing renewable 
energy. Limestone-derived products are integral 
in infrastructure projects related to electric grid 
upgrades, enabling the efficient distribution and 
utilisation of electricity. 

Electrification in Europe is not only essential 
for achieving net-zero emissions but also for 
driving efficiency and productivity across various 
sectors. By 2030, nearly two-thirds of emissions 
reduction in the European Union is projected to 
be accomplished through energy efficiency and 
electrification initiatives. The trend of electrification 
in Europe goes beyond personal vehicles, 
encompassing crucial sectors like lithium battery 
production and the electric grid. Lithium battery 
production is vital for powering electric vehicles and 
storing renewable energy. Upgrading the electric

ENVIRONMENTAL PROTECTION

HOW WE ARE RESPONDING

The mega trend of environmental protection in 
Europe is gaining momentum, with innovative 
applications emerging to safeguard crucial 
ecosystems and combat pollution. Efforts such as 
ocean and lake liming are being explored to restore 
acidity balance and promote marine biodiversity. 
Additionally, initiatives like Air Pollution Control 
Residues cleaning tackle industrial waste, 
ensuring cleaner air and waterways. Shipping 
emissions, a significant contributor to pollution, 
are being addressed through regulations and 
advancements in green technology. Moreover, the 
concept of direct air capture is gaining traction, 
offering a promising solution to remove carbon 
dioxide from the atmosphere. As Europe prioritises 
environmental stewardship, these diverse 
approaches underscore the region's commitment 
to preserving natural resources and mitigating the 
impacts of climate change.

In ocean and lake liming, limestone is used to 
neutralise acidity and restore pH balance, thereby 
enhancing water quality and fostering the growth 
of aquatic life. Air Pollution Control Residues 
cleaning often involves the use of lime to treat 
industrial waste, neutralising harmful pollutants 
and reducing environmental impact. Lime is also 
employed in shipping emissions control, where 
it serves as an absorbent for sulphur dioxide 
emissions, mitigating air pollution from maritime 
activities. Furthermore, in the emerging field of 
direct air capture, lime-based sorbents are being 
explored as a means of capturing carbon dioxide 
from the atmosphere, aiding in climate change 
mitigation efforts.

2019  and  has  been 
instrumental 
in  developing  the  Group  in  Europe. 
Until  December  2023,  Emmanuel 
was  in  charge  of  the  Group’s  West 
region,  developing  its  two  platforms 
from  acquisition  to  full  integration. 
His  work  included  the  restructuring 
of  the  Aggregates  and  Dimension 
stone  businesses  and  the  delivery 
of  significant  performance  uplifts  in 
both. Additionally a concrete focussed 
platform was established containing 7 
operational sites. 

Previously Emmanuel served as CEO of 
Group De Cloedt (2004-2018), a Belgian 
in  dredging, 
company  specialising 
production  and  commercialisation  of 
sand,  gravel  and  hardstone,  building 
the  business  from  €40  million  to 
€240  million  annual  turnover,  through 
organic growth and acquisitions.

The  mandate  of  this  unit  is  threefold.  Firstly,  coordination 
of  all  acquisition  and  divestment  activities;  secondly  the 
origination  and  execution  on  strategic  partnerships  and 
initiatives; thirdly, the preparation of certain businesses for 
further integration into the Group’s key regions. 

The  activities  of  this  new  unit  have  been  numerous.  In 
the  early  parts  of  2023,  it  coordinated  an  ambitious  plan 
to  acquire  up  to  8  bolt-on  companies  across  Europe,  6  of 
which have since been acquired.  It coordinated the disposal 
of four non-core assets and prepared the ground for further 
organic  expansion  and  partnership  initiatives.  Looking 
ahead the unit will play a pivotal role in the Group’s strategy. 

Where a lot of the growth came from pure M&A work in the 
past, the Group’s new structure and scale will favour further 
organic investment and development work. Several projects 
currently undertaken are listed below. 

In order to achieve its goals the unit calls upon two further 
teams - finance and technical teams – within the Group to 
supplement its capabilities at times when the activities are 
most intense. In years to come we anticipate the workload 
of this team will increase and its delivery will be a key driver 
of the Group’s progress.

Group structure

Following the transformational acquisition of Nordkalk in August 2021, the Group’s geographical 
footprint, product offering and end-user markets changed substantially. Whilst wishing to retain 
the established platform model, which has proven effective in ensuring the businesses remain 
locally  focused  and  agile,  we  saw  the  potential  to  enhance  this  through  additional  Group  level 
structure to support further growth and expansion.

In 2022 we augmented our platforms with an overarching regional structure. Each region has a Managing Director and Financial 
Director who are responsible and accountable for overseeing performance, steering development and driving growth.

The regional structure aligns the Group as follows:

1 La Belonga was acquired by Nordkalk and in 2023 reported into the North East Region; this will be reviewed as the Group develops.

As part of the CRH Lime Acquisitions, the Group is expanding 
this  structure  to  include  a  new  Central  Region,  which 
consists  of  Germany  and  Czechia,  as  well  as  separating 
the  North  East  Region  into  two,  with  the  North  Region 
comprising  Finland,  Sweden,  Norway  and  the  Baltics,  and 
the East Region comprising Poland and Ukraine.

Construction minerals are quarried lower-grade limestone 
or granite products, crushed to various size specifications, 
and  sold  as  aggregate  or  processed  into  value-added 
products such as concrete blocks, pre-cast concrete, ready-
mix concrete, and asphalt. Construction mineral customers 
range from:

At  a  product  level,  the  Group  was  structured  around 
three  core  product  categories  which  it  used  to  assess 
performance,  being 
industrial  minerals,  construction 
minerals and dimension stone.

processed through re-carbonation. Industrial minerals also 
include  other  high-grade  specialised  minerals  such  as 
dolomite and wollastonite. Industrial mineral customers are 
typically  large  national  or  multinational  corporates  under 
fixed  annual  supply  agreements  over  long-term  contracts. 
In  most  cases,  these  contracts  include  dynamic  pricing 
mechanisms to adjust for changes in the price of key input 
costs such as energy and logistics.

stone is used in the construction market for infrastructure 
and  residential  projects  as  tiles,  skirtings,  paving,  cladding 
and  bespoke  applications  such  as  kitchen  benches  and 
swimming pools. Dimension stone customers include stone 
transformers and cutters, wholesalers, building merchants 
and contractors. Customer contracts range from multi-year 
development projects, structured supply arrangements and 
periodic or one-off orders.

In  terms  of  end-markets,  the  Group  broadly  fits  into  two 
primary  categories,  being  construction  materials  and 
industrial minerals.

Lime  and  high-grade 
limestone  materials  have  many 
industrial applications, ranging from fillers in the production of 
cardboard to reactive agents in the treatment of flue gas, soil 
and water. The Group’s industrial mineral markets comprise:

•  Pulp, paper & board: Quicklime is required in the closed 
chemical  circulation  of  modern  pulp  mills,  helping 
decrease  environmental 
impact  of  the  production 
process. Approximately 250 kg of quicklime is required 
to  produce  a  tonne  of  pulp.  Quicklime  and  limestone 
are  also  used  as  filler  in  the  production  of  paper  and 
cardboard and more broadly in effluent treatment.

•  Metals & mining: Quicklime and limestone are used in 
various  metal  production  applications,  including  steel 
and copper production and metal recycling. Quicklime 
is  also  an  important  chemical  for  regulating  various 
processes in the mining industry.

• 

Environmental:  Quicklime,  slaked  lime  and  limestone 
powders  are  used  to  remove  acidic  compounds  such 
as  sulphur,  chlorine  and  fluorine  from  flue  gas  before 
the chimney. Quicklime and slaked lime are also used 
to treat water, raising the pH level of drinking water and 
reducing toxicity of wastewater.

•  Agriculture:  Quicklime

sustainable  and  more  productive  agriculture,  both  in 
terms of livestock and farming. Limestone is also used 
to increase soil pH and in animal feed.

is  critical 

•  Chemical:  Finely  ground  limestone  powders  are  used 
as  fillers  in  paint  and  adhesives.  Wollastonite  is  also 
used to enhance properties of paint, plastics and other 
unique applications.

Quarried  limestone  and  granite  minerals  are  used  in  the 
construction of roads, concrete and other building materials. 
Construction materials markets are broadly categorised as 
either infrastructure or residential:

• 

Infrastructure:  Uses  quarried  limestone  or  granite 
minerals  in  the  construction  of  large  infrastructure 
projects such as roads, railways, bridges, ports, airports 
and  commercial  buildings.  Primary  products  include

North West

The North West Region is led by Michael Roddy and geographically covers England, Wales and 
the Channel Islands. It comprises four platforms which are detailed below. The North West is 
primarily  focused  on  the  construction  industry,  which  accounts  for  99%  of  revenue,  and  the 
core product group is therefore construction minerals, including pre-cast concrete and concrete 
products, ready-mix concrete, asphalt and surfacing, dimension stone and aggregates.

of  Rightcast  and  Retaining, 
together  with  organic 
improvement in the underlying businesses.

Construction  mineral  volumes  were  down  as  a  result  of 
JQG, CCP and Allen. JQG endured delays in infrastructure 
project  work,  which  impacted  quarry  performance,  while 
CCP  and  Allen  have  relatively  large  exposure  to  UK 
residential construction.

It is testament to the quality of the management teams in 
the North West that they were able once again to increase 
earnings while experiencing softening volumes.

PPG

PPG is a group of companies specialising in 
manufacturing  precast  concrete  products 
and  blocks.  The  platform 
includes  Allen 
Concrete,  Poundfield  Precast,  CCP  Building 
Products,  Rightcast  and  more 
recently 
Retaining.  With  a  triangulation  of  bases  in 
London,  on  the  East  Coast  and  in  the  North 
West,  PPG  supply  a  wide  and  diverse  range 
of industries ranging from house builders and 
farmers to national sea defence projects and 
international  contractors,  both  directly  and 
through merchants.

The PPG companies are some of the most experienced and 
innovative in their industry with some operating for over 70 
years and collectively owning a significant number of patents 
and licences. 

PLATFORM HIGHLIGHTS 

2023 has been a very successful year for the PPG platform, 
with  further  growth  across  the  businesses  and  another 
acquisition.

The  health  and  well-being  of  our  staff  remained  our  most 
important  objective.  To  aid  this,  in  2023  we  launched 
“Peptalk”,  an  app-based  platform  designed  to  promote 
employee engagement and wellbeing.  Continued focus on 
behavioural safety techniques has led to a further reduction 
in  incident  severity  and  frequency.  Safety  pitstops  were 
completed  across  the  platform  with  focus  on  core  risks, 
further enhancing the proactive safety culture.

In  terms  of  business  performance,  Poundfield  achieved 
further  growth  in  2023,  increasing  revenue  by  6%  over 
the  previous  year.  The  bespoke  division  continued  to  see 
advancement in the size, scale and complexity of projects, 

undertaking  significant  jobs  for  HS2  and  Mace  along 
with  a  landmark  cement  free  concrete  project  for  the  UK 
Environment  Agency.  Capital  investment  at  the  Creeting 
operation included the replacement of diesel forklift trucks 
with electric to reduce carbon emissions, and the continued 
increase  in  storage  capacity,  enabling  the  business  for 
further growth. 

Due to the slowdown in the residential construction market 
CCP executed proactive cost control, enabling the business 
to  deliver  a  strong  result  in  a  difficult  market.  As  part  of 
this process the business reduced its cost base by during 
the  year,  also  placing  itself  in  a  strong  position  entering 
2024.  Development  in  technology  further  enhanced  our 
ultra-low carbon concrete (ULCC) with all products offering 
carbon savings as standard (vs 100% cement alternative). 
The  installation  and  commissioning  of  a  new  wash  plant 
at  Aberdo  quarry  was  completed  in  the  second  half  of 
the  year,  offering  premium  washed  aggregates  previously 
designated  as  waste,  in  turn  releasing  approximately  5 
million tonnes of limestone reserve.

Allen  had  another  successful  year,  maintaining  continued 
high service levels, which coupled with close relationships 
to  our  loyal  customer  base,  resulted  in  a  strong  customer 
retention  rate  within  a  competitive  market.  Further 
investment  at  our  Wellingborough  plant  resulted  in  the 
automation  of  a  greater  range  of  products  reducing  lead 
times,  strengthening  our  product  offering  and  reducing 
operating  costs.  A  review,  focus  and  site  improvements 
in  respect  of  the  businesses’  core  health  and  Safety  risks, 
resulted in an LTI free year.

Rightcast maintained its strong financial performance since 
its  acquisition  the  previous  year,  maintaining  LFL  sales 
revenue  and  margin.  Capital  investment  was  focussed  on 
improving the standard of employee welfare facilities.

In  April  2023  Retaining  joined  the  platform  and  has  gone 
from strength to strength since, exceeding expectations and 
the original forecast model.

STRATEGIC REPORTSIGMAROC ANNUAL REPORT 2023PLATFORM HIGHLIGHTS 

In 2023, our core focus remained on enhancing the health, 
safety and well-being of our staff across all our businesses. 
We  have  continued  to  refine  our  behavioural  safety 
techniques,  leading  to  a  decrease  in  incident  severity  and 
frequency. Specifically, we are conducting a comprehensive 
health & safety review of competence and training to further 
bolster our safety culture.

Financially,  Johnston's  performance  was  bolstered  by  a 
thorough  review  of  operating  costs  and  integration  into  the 
SigmaRoc  supply  chain,  resulting  in  substantial  savings. 
Our commitment to high levels of customer service, strong 
customer relationships, and top-quality products has resulted 
in exceptional customer retention throughout the year.

Moving  forward,  our  Bath  Stone  Group's  focus  is  on 
developing  the  mine  to  produce  high-value  dimensional 
stone products, positioning the company for future growth 
and increased market share. Plans are underway to initiate 
secondary processing of historic and new waste streams to 
generate additional income and create valuable void space, 
supporting continued expansion in the coming year.

Our  strategic  review  of  operations  within  Building  Stone 
has  identified  key  areas  of  operational  efficiencies.  We 
anticipate  realising  these  efficiencies  in  2024,  contributing 
to our ongoing growth and success.

In  our  quarries  division,  we  observed  strong  production 
levels, an improved health and safety culture, and strategic 
investment across all sites, fostering further growth in the 
year and positioning the business for sustained, profitable 
expansion in the years ahead.

Notably,  the  most  encouraging  aspect  of  the  year  within 
Johnston  was  the  continued  integration  of  the  business, 
its people, supply chain and loyal customers into the wider 
SigmaRoc Group.

As  we  look  to  the  future,  numerous  opportunities  exist 
across  all  sectors  of  the  business  to  enhance  efficiencies 
and  output.  With  a  new  leadership  structure  in  place 
bringing  significant  industry  experience,  we  are  poised  to 
further elevate our operations. Furthermore, a full cost base 
review has us well positioned for 2024, providing significant 
headroom for growth when market conditions improve.

Wales

Harries is the cornerstone for SigmaRoc’s 
Welsh  platform.  Following  the  Group 
taking  100%  ownership 
in  September 
2020, we have a significant footprint in the 
region  with  opportunities  to  expand  the 
businesses organically and acquisitively.

Harries  is  one  of  Wales’  largest  independent  suppliers 
of  aggregates.  Based  in  West  Wales,  it  operates  out 
of  six  granite  and  limestone  quarries  incorporating 
three  asphalt  plants,  eight  concrete  plants  and  a 
wharf  operation,  as  well  as  a  civil  engineering  division 
delivering significant infrastructure projects.

Following  the  award  of  the  SWTRA  contract  and  in 
preparation for tendering of the NMWTRA contract, the 
business has been restructured into two divisions:

1. 

2.  

 Construction  Materials,  which  focuses  on 
aggregates and ready-mix concrete.

 Construction Services, which focuses on civil 
engineering, road surfacing, road construction  
and asphalt.

PLATFORM HIGHLIGHTS 

The Wales Platform achieved steady organic growth during 
2023, which is attributed to strong price improvements and 
better operational efficiency. 

The  £1.5M  primary  crusher  CapEx  project  at  Bolton  Hill 
was  completed  and  delivered  operational  improvements 
throughout  the  second  half  of  the  year.  Work  commenced 
on  the  new  asphalt  plant  in  Llandarcy  (£3.6m  Growth 
Investment)  and  has  progressed  well  with  commissioning 
and first commercial sales commencing in March 2024.

Harries delivered several successful major projects through 
the  SWTRA  surfacing  framework  and  also  secured  a 
position on the Southwest Wales Regional Civil Engineering 
Contractors framework, which is worth an estimated £9m in 
net sales over three years.

Innovation  continued  to  be  a  key  focus  during  2023,  with 
Harries  developing  several  innovative  concrete  mixes  to 
support  specific  project  requirements.  Harries  progressed 
the  development  of 
low  carbon  concrete  mixes  and 
introduced liquid screed to our Cardigan ready-mix plant, to 
open up new territory for this market.

With  regard  to  sustainability,  Harries  supported  and 
delivered  several  renewable  projects  at  the  Celtic  Freeport 
in  Pembroke  and  continued  to  develop  internal  renewable 
projects at three key sites, securing grid connections for the 
projects in the year. Harries also developed a partnership to 
investigate the feasibility of replacing fossil fuels with Green 
Hydrogen with Trafigura and H2Energy.

Harries  also  completed  a  carbon  baseline  assessment 
and  a  net-zero  reduction  plan,  which  will  be  supported  by 
internalising renewable energy sources.

PLATFORM HIGHLIGHTS

The  headwinds  that  developed  during  2022  intensified 
Islands  Platform  during  2023,  with 
for  the  Channel 
exceptionally  high 
interest  rates 
impacting the commercial viability of many developments. 
These factors also contributed to high profile insolvencies 
in  the  construction  sector  which  precipitated  a  loss  of 
confidence in parts of the market.

inflation  and  rising 

Whilst  housing  and  commercial  development  remained 
subdued,  asphalt  and  our  contracting  business  saw 
improved volumes and increased market share.

Aggregate volumes were also very strong in Guernsey, with 
significant contracts being supplied in power infrastructure 
and  the  sports  sector.  This,  combined  with  the  strong 
asphalt performance, whilst also benefitting from ongoing 
productivity  and  efficiency  gains,  resulted  in  a  platform 
EBITDA that was broadly in line with the prior year.

Development  work  for  the  quarry  extension  in  Jersey  and 
for  the  new  quarry  at  Chouet  in  Guernsey  progressed  to 
plan,  with  both  sites  to  be  operational  in  2024,  providing 
reserves  that  will  underpin  the  business  through  the  next 
two decades and beyond.

The  underlying  housing  demand  in  the  islands,  together 
with  considerable  investment  that  is  planned  in  ports, 
health  and  educational  infrastructure,  is  anticipated  to 
create a considerable increase in demand across all product 
streams in the mid-term.

Revenue  and  underlying  EBITDA  are  up  YoY  through 
a  combination  of  the  acquisitions  of  Goijens  and 
Betons  during  the  year,  organic  improvement  in  the 
underlying businesses, and effects of dynamic pricing

The  primary  drivers  of  the  organic  improvement  in 
the  West  Region  were  proactive  cost  management 
in  CDH,  mitigating  the  impact  of  softer  volumes,  and 
then across the Benelux platform, in particular Goijens, 
which increased underlying EBITDA by over 50% LFL.

Construction  mineral  volumes  were  steady  YoY, 
however dimension stone experienced some softness 
due to weakening residential demand and this carried 
through into revenue.

The acquisition of Goijens and the creation of Betons 
saw an increase in staff and sites in the West Region.

Dimension Stone

CDH is the world’s largest producer of Belgian blue limestone. CDH presently produces around 
115,000  cubic  metres  of  blocks,  together  with  around  800,000  square  metres  of  sawn  blocks, 
of high quality Belgian Bluestone per year, a high-grade dimension stone produced exclusively in 
Belgium under European protected status. Belgian bluestone can be found in infrastructure and 
residential projects across the globe.

Our Dimension Stone platform is well positioned with reserves 
and  resources  of  over  150  million  tonnes  of  construction 
aggregates and over 28 million cubic metres of high quality 
Belgian  Bluestone.  The  business  employs  over  420  people 
and has a proud history dating back 130 years.

Due  to  its  high  quality  and  distinctive  characteristics, 
Bluestone  is  a  Global  Heritage  Resource  and  a  sought-
after product that travels worldwide (unlike most aggregate 
products). Bluestone can be used in residential, commercial 
and infrastructure projects, as well as for architectural and 
cosmetic applications.

Benelux

Following the Group taking-over of all LafargeHolcim’s production installations located at CDH in 
April 2021, shortly followed by the acquisitions of the B-Mix and Casters businesses in Belgium, 
SigmaRoc  created  the  Granulats  du  Hainaut  aggregates  brand  and  separated  its  European 
heavy-side materials operations into two separate platforms. 

CDH  continued  as  a  Europe  wide  dimension  stone 
platform and a new, integrated, concrete and construction 
aggregates  Benelux  platform  was  created,  including  the 
GduH,  Cuvelier,  B-Mix  and  Casters  businesses.  There  are 
>190Mt  of  aggregate  reserves  and  resources  attributable 
to  the  Benelux  platform,  in  addition  to  the  CDH  bluestone 
reserves and resources.

The  Benelux  platform  produces  over  2  million  tonnes  of 
aggregates  and  over  350,000  m3  of  concrete,  servicing 
the  Hainaut,  Liege  and  Limburg  markets.  Our  aggregate 
products  supply  a  range  of  partners  and  construction 
companies  with  products  for  concrete,  sea  defence  work 
and riverbank fortification.

The aggregates business is led by Christophe Huyghebaert 
and concrete by Dirk De Leus.

PLATFORM HIGHLIGHTS

The Belgian ready-mix concrete plants had a very strong year, 
with dynamic pricing and active cost control translating into 
improved  profitability.  Cuvelier  also  reported  a  good  year, 
bolstered  by  strong  market  demand  that  led  to  increased 
production volumes and solid profit margins.

Our quarry in Soignies, Granulats du Hainaut, also performed 
commendably. The volumes produced were in line with our 
projections,  primarily  driven  by  our  contract  with  Holcim, 
resulting  in  the  quarry's  EBITDA  being  in-line  with  budget. 
Looking  ahead  to  2024,  Granulats  du  Hainaut  is  gearing 
up  for  a  busy  year.  This  includes  the  establishment  of  a 
new  sales  and  logistics  department,  a  strategic  move  in 
anticipation of the conclusion of the Holcim contract at the 
end  of  2024.  Additionally,  the  quarry  is  set  to  commence 
investments in a new crushing and screening plant.

Toward  the  end  of  2023  the  Benelux  platform  expanded 
into the North of France with the acquisition of four ready-
mix concrete plants from CdB. The plants are strategically 
located near the Soignies quarry and operated under newly 
incorporated Betons.

reporting and disclosure of both mandatory and voluntary 
ESG and sustainability matters.

STRATEGIC REPORTSIGMAROC ANNUAL REPORT 202395

Sustainability  Recognition  and  Commitment  –  Currently 
holding  a  AA  rating,  we  are  recognised  as  a  “Leader”  in 
our sector by MSCI. This year we registered with CDP and 
submitted our first Climate Change questionnaire, and await 
validation of our emissions reduction targets from the SBTi.

STAKEHOLDER  ENGAGEMENT  AND  MATERIALITY 
ASSESSMENT

We  continually  engage  with  a  wide  array  of  internal  and 
external  stakeholders  to  identify  the  key  sustainability 
issues  that  matter  most  to  the  Group  and  to  our  core 
stakeholders.  Our  findings  have  guided  our  ESG  journey, 
through setting strategic sustainability performance targets 
against  each  material  issue.  We  report  on  our  progress 
against  the  strategic  targets  set  and  further  information 
on  our  Materiality  Assessment,  including  our  Materiality 
Matrix. 

SECR – We continue to report our energy consumption and 
Scope 1-3 greenhouse gas emissions according to the SECR 
regulations, including non-mandatory aspects to ensure full 
transparency of our emissions and intensity ratio.

TCFD – This is the first year we have fully reported against 
the  recommendations  and  recommended  disclosures  of 
the  Taskforce  on  Climate-Related  financial  disclosures 
(TCFD),  under  the  Companies  (Strategic  Report)  (Climate-
related  Financial  Disclosure)  Regulations  2022. The  report 
was  developed  in  conjunction  with  external  consultants. 
The report has been reviewed by both the Audit Committee 
as well as the Company Auditors. The report can be found 
on page 124 of this report.

SASB – We continue to use SASB as a guiding principle for 
disclosure of metrics that are material to our industry as per 
the SASB materiality matrix.

SBTi  –  In  line  with  our  stated  ambition,  this  year  we  have 
submitted  our  Scope  1-3  carbon  footprint  alongside 
our  emissions  reduction  targets  data  to  SBTi.  We  have 
committed  to  reducing  our  Scope  1&2  emissions,  and  to 
reducing our Scope 3 emissions, aligned with the ambition 
and  emissions  reduction  trajectory  required  to  curb  global 
temperature rise to 1.5ºC.

European  Energy  Directive  –  UK  ESOS  report  has  been 
compiled and will be submitted in line with UK submission 
requirements.

Our ESG Journey

Stakeholders (in

Description

How we engage

Colleagues

Customers and 
Suppliers

We have a dedicated workforce of c. 2,000 
across the Group. We recognise our dedicated 
workforce as a key driver of the value derived 
from the business. Our colleagues are 
experienced and continuously developed to fulfil 
their potential. All employees are offered a fair 
benefits and compensation package relative 
to their role and level in the organisation. We 
encourage share ownership where it is available 
and, where possible, are working to setup where 
it is not currently in place.

All our businesses are decentralised and locally 
focused so that we know the customers’ and 
suppliers’ areas like they do. We work alongside 
our customers to provide “right first time” 
service and to seek proactive and innovative 
solutions to support requirements. “Right first 
time” is key to success and ensuring customer 
loyalty as part of our long-term success. We 
recognise the huge role our suppliers play in our 
long-term success. We strive to ensure timely 
payments and maximise value to support the 
delivery of our customers’ needs. We balance 
economic requirements with sustainability 
considerations over the whole supply chain.

Site presence and visual felt leadership. 
Employee groups and committees and unions. 
Focus on development training and succession 
planning. Decentralised approach with flat 
management allowing easy access to all staff. 
Employee benefit offerings that can also extend 
to family members.

Prioritise a local focus on both customers and 
suppliers. Engage directly from our sites so 
that the customer and supplier deal directly 
with the site they are supplying or buying from. 
Ensure timely payments are made to suppliers. 
Functional and intuitive websites and digital 
solutions focused on the customer. Ensure 
adequate checks and due diligence are done on 
customers and suppliers.

Communities

By being decentralised and local we are at 
the heart of the communities in which we 
operate allowing us to be good, knowledgeable, 
supportive and engaging neighbours.

Proactive approach and active participation 
in community and industry working groups, 
forums and committees.

Investors

All our Shareholders play an important role in 
the continued success of our business. We 
maintain purposeful and close relationships with 
them either directly or via wider mediums such 
as Q&A webinars and conferences. We seek to 
be transparent and give clear and consistent 
messages across all communication channels.

Dedicated forums such as AGM, annual and 
interim webinar Q&As and/or interactive investor 
presentations. Annual and interim reports, 
trading statements and RNS. Regular phone 
calls and dialogues. Broker and NED contacts. 
Site visits, investor roadshows, investor 
conferences.

Regulators / local 
Government

We look to develop and sustain good 
relationships with many regulators who govern 
our businesses to ensure the success of our 
business and maintaining our license to operate. 
We are committed to adherence of legal and 
regulatory requirements. We are committed 
to have independent review / oversight be it 
internally or externally. We are committed to a 
sustainability framework following review of 
international standards.

Regular dialogue with Governments, 
Government agencies, regulators and industry 
groups. Active membership of the industry 
bodies such as Mineral Products Association, 
Federation Industries Extractives and European 
Lime Association. Effective and clear policies to 
ensure governance. Education and training of 
staff to reinforce compliance with regulations.

STRATEGIC REPORTSIGMAROC ANNUAL REPORT 2023CO2 AND THE LIME INDUSTRY AND HOW IT VARIES FROM 
CEMENT AND OTHER INDUSTRIES

To  deal  with  CO2,  it  is  crucial  to  understand  how  CO2  is 
governed and how it is produced.

European Union Emissions Trading System (EUETS) 

The EUETS regulates greenhouse gas emissions of energy 
and  energy-intensive  industries  as  well  as  inner-European 
aviation.  The  EUETS  puts  a  cap  on  the  carbon  dioxide 
(CO2) emitted by business and creates a market and price 
for  carbon  allowances.  It  covers  45%  of  EU  emissions, 
including  energy 
intensive  sectors  and  approximately 
12,000 installations.

The  EUETS  works  on  the  ‘cap  and  trade’  principle.  A  ‘cap’, 
or  limit,  is  set  on  the  total  amount  of  certain  greenhouse 
gases  that  can  be  emitted  by  factories,  power  plants 
and  other  installations  in  the  system  within  the  cap,  and 
companies receive or buy emission allowances which they 
can consume or trade as needed.

An allowance gives the right to emit a tonne of CO2, and any 
allowance surplus to requirement can be accumulated and 
used to offset future emissions or traded.

97

The directive concerning Phase IV (2021-2030) of the ETS 
entered  into  force  on  8  April  2018.  Secondary  legislation 
and guidance documents defining the revised ETS scheme 
were published in 2023 to align it with the target of a 55% 
reduction  of  EU  Green  House  Gas  emissions.  The  new 
benchmark  values  (the  value  at  which  the  free  allowance 
is  set)  are  below  the  actual  emissions  of  the  covered 
industries,  and  this  deficit,  along  with  market  measures 
such  as  a  stability  reserve  held  by  the  EU  and  the  faster 
reduction in year-on-year allowances drove traded prices in 
2023 up to values of €80-€100/tonne, though at the time of 
publishing they have dropped.

Recently the Cross Border Adjustment Mechanism (CBAM) 
was  brought  in  for  many  industries,  including  cement. 
Lime however is not part of CBAM. CBAM is a mechanism 
whereby importers of materials such as steel and cement 
into  Europe  will  have  to  pay  a  duty  /  tax  to  ensure  that 
European  business  and  importers  are  equally  priced  with 
regards  to  carbon  costs.  In  order  for  those  industries  to 
protect their boundaries, the consequence was to relinquish 
all free allocation by 2034 compared to allowing allowance 
to  run  until  the  2050  timeline  associated  with  the  current 
legislation. As previously mentioned, lime is excluded from 
this and will continue its gradual reduction of free allocation 
under the existing rules.

Lime Industry and CO2
Lime Industry and CO2
For lime there are sources of CO2 along the production process, however there are two primary sources that make up the 
majority of CO2 emissions: fuel and process emissions from the calcination part of the process.

The calcination process is simply the formula of deriving CaO from CaCO3 using heat.

CaCO3

Energy

CaO

CO2

The  two  main  sources  of  CO2  from  the  calcination  part  
of  the  process  are  as  follows:  Combustion  CO2  (~25% 
to  35%)  is  produced  from  the  burning  of  fossil  fuels, 
while  process  CO2  (~65%  to  75%)  results  from  the  actual 
calcination of limestone. 

Power  and  energy  CO2  can  be  reduced  through  energy 
efficiency, renewable electricity, fuel efficiency and renewable 
/  alternative  fuels.  We  are  actively  working  on  renewable 
energy solutions and Power Purchase Agreements.

Combustion CO2 can be reduced by energy efficiency and 
fuel  selection,  as  well  as  by  carbon  capture  utilisation  or 
sequestration  (CCUS).  We  have  achieved  success  with 
fossil free lime calcination, achieving 100% substitution by 
biomass at one site. Our first Carbon Capture unit has also 
been successfully installed and commissioned.

Process CO2 can only be addressed by CCUS, with our first 
Carbon Capture unit having been successfully installed and 
commissioned.

Carbon capture utilisation or sequestration

The emissions from lime kilns are well suited to technologies 
such as CCUS as they have a higher CO2 content than most 
post-combustion  gases  and  contain  fewer  contaminants 
due to using only limestone as feedstock and, due to product 
requirements, more stringent fuel quality requirements and 
typically lower gas filtration temperatures.

Post-combustion  capture  (PCC)  systems  constitute  a 
technically  and  economically  viable  solution  to  reduce 
emissions  in  a  variety  of  sectors.  Retrofitting  existing 
plants with post-combustion capture units may be the only 
effective and economically viable way to reduce emissions 
at  the  stack,  without  affecting  the  process  upstream.  The 
availability  of  a  range  of  commercially  ready  technologies 
suitable  for  different  types  of  CO2  point  sources  is  crucial 
for the wide deployment of CCUS systems. Given the wide 
ranges  of  plant  sizes  and  flue  gas  specifications  relevant 
to  different  emitting  sources,  it  is  unlikely  that  a  single 
technology could fit best in all cases. Therefore, for effective 

process  design,  it  is  convenient  to  consider  multiple 
technologies and select the most efficient and economically 
viable option to serve the purpose. 

In addition to the membrane technology currently in use by 
SigmaRoc,  there  are  a  few  other  options,  some  of  which 
are more traditional and geared towards large emitters with 
each solution having their own opportunities and risks:

•  Amine scrubbing is acknowledged as the most mature 
CCUS  solution.  Absorption-based  processes  for  the 
separation  of  CO2  from  flue  gases  have  been  widely 
researched,  and  their  effectiveness  has  been  proven 
through  testing  on  a  variety  of  scales,  from  laboratory 
to commercial. For lime, this solution is both costly and 
requires  a  substantial  footprint  with  significant  energy 
consumption and issues with disposal of waste residues.

•  Cryogenic  capture  and  separation  is  a  more  recent 
development  offered  by  industrial  gas  companies 
as  an  extension  of  their  in-house  process.  For  lime, 
this  solution  is  both  costly  and  requires  a  substantial 
footprint with significant energy consumption.

SigmaRoc believes that membrane technology is optimally 
suited to our single kilns / small cluster of kilns due to the 
proven technology, small footprint, low capital and operating 
costs and high efficiencies. For our sites that have multiple 
kilns  with  larger  emission  volumes,  carbon  capture  can 
be  done  via  membrane,  but  also  by  other  technologies, 
allowing a flexible approach to carbon capture based on the 
site, infrastructure and country policies and legislation.

Other technologies, that may be more suited to the SigmaRoc 
kiln  network,  are  being  trialled  and  investigated  including 
Ocean  GeoLoop  which  employs  an  all-electric  pressure 
swing process for CO2 capture where a trial plant designed 
to  capture  10,000  tonnes  of  CO2  is  to  be  established  with 
Nordkalk’s joint venture partner in Norway.

This  allows  the  Company  to  constantly  select  the  best 
option for both its operations and its operating jurisdictions.

CASE STUDIES

Aqualung update and NoFraKalk

In 2023, SigmaRoc successfully installed and commissioned 
its  first  carbon  capture  unit  at  Nordkalk’s  site  in  Köping, 
Sweden. The fully scalable carbon capture system, utilising 
Aqualung’s  innovative  membrane  technology,  is  the  first-
ever implementation of its kind in the industry.

The  carbon  capture  system  has  been  developed  by 
Aqualung,  a  leading  provider  of  membrane-based  carbon 
capture and separation technology, based in Norway.

Over the course of the preceding year, SigmaRoc reviewed 
an  array  of  technologies  including  amine  absorption,  solid 
absorption,  membrane  and  cryogenic.  The  Aqualung 
membrane  technology  was  considered  best  suited  for  the 
Group’s  operations  based  on  the  following  factors:  small 
footprint,  low  CapEx  and  operating  costs,  and  a  relatively 
low complexity and efficient solution. The system is modular 
and  fully  scalable,  allowing  SigmaRoc  significant  flexibility 
in the roll out of the solution.

The Aqualung module installed in Köping can capture up to 
25% of the process emissions emitted from a standard kiln 
and was initially designed as a ‘catch and release’ system to 
demonstrate the durability and efficiency of the membranes. 

The unit is able to capture CO2 with a purity of 96% through 
just 2 stages. 

The unit has been connected to a pilot purification module to 
simulate settings required to produce higher purities of CO2 for 
different end use applications that go beyond sequestration 
requirements.  We  believe  review  of  alternative  application 
is  required  whilst  European  Governments  and  third  parties 
develops legislation, policies and sequestration infrastructure 
including pipeline, storage facilities and portside facilities to 
allow for commercially available sequestration.

SigmaRoc  is  working  with  various  businesses  and  solution 
providers  with  regards  to  the  end  use  of  CO2,  including 
being  involved  with  the  NICE  (Norvik  Infrastructure  CCS 
East  Sweden)  project  to  explore  all  CO2  utilisation  and 
sequestration options.

Nordkalk also secured part-funding from the Swedish Energy 
Agency  for  the  implementation  and  scaling  of  the  Köping 
carbon system with the intention to capitalise on the learning 
from the engineering, commissioning and operation phase of 
the initial module.

As  part  of  the  Groups  JV,  Norfrakalk  in  conjunction  with 
Ocean GeoLoop are initiating an industrial trial plant designed 
to  capture  10,000  tonnes  of  CO2  in  Norway  using  an  all-
electric pressure swing process.

Biodiversity

The concept of dynamic biodiversity management combines integrated management of the operation of an active quarry with 
dynamic  preservation,  management  and  restoration  measures  for  species  and  habitats.  This  principle  makes  it  possible  to 
integrate the populations of species present in the quarry into a network of habitats ensuring constant availability of environments 
conducive to their development.

We have integrated the dynamic management of biodiversity into its extraction activity as part of the Life in Quarries project 
and have conducted annual monitoring to assess the structure and functionality of the habitats created. Since 2020, in Belgium 
we have ensured compliance with a management plan in response to local biological issues using the tools and skills acquired 
as part of the Life in Quarries project. A summary of activities in 2023 is set out below:

During 2023, specific training was given by the University of 
Gembloux on two areas: 

Pollinators

the  awareness  about 

Career  pollinators  and 
the 
disappearance  of  wild  bees  which  are  essential  for 
biodiversity  and  a  large  part  of  the  crops  intended  for  our 
food. Pollinators need quality food resources at each stage 
of their life, winter nesting sites, construction materials for 
nesting and shelter to protect themselves from the wind and 
predators all whilst considering light pollution.

Planting hedges in Quarries

With  their  gradual  disappearance  throughout  the  country, 
hedges  have  taken  away  the  multiple  roles  they  fulfilled. 
They  have  local  and  regional  ecological  importance  by 
diversifying  the  landscape  and  providing  habitat  and  food 
resources  for  many  species.  They  fulfil  other  roles  of 
ecological  connectivity  and  provide  a  range  of  ecosystem 
services, shading, fight against runoff, improvement of soil 
quality. They also support the quarry in other services: fight 
against  erosion,  protective  barrier,  sound  insulation.  They 
can constitute an additional opportunity to contribute to the 
conservation of Biodiversity in the quarry.

STRATEGIC REPORT

Puccini Blue

Waste reuse & Circular Products

Circular solutions have been a large focus in 2023 with the 
extension  and  launch  of  several  sustainable  product  lines, 
such  as  Greenbloc,  Mevo,  MTech,  Puccini  Blue,  Nordkalk 
Next and Nordkalk Complete on industrial scales.

Mevo

Mevo is a revolutionary new technology for the grinding and 
blending  of  non-cementitious  minerals,  imparting  certain 
binding  properties  to  the  materials.  The  Company  has 
supported Mevo in raising £15m in venture funding and has 
assisted in the construction of its first large-scale plant. Once 
operational,  we  anticipate  that  Mevo’s  technology  will  be  at 
the forefront of decarbonising all our concrete products.  

Greenbloc

Through 2023 Greenbloc technology has made significant 
strides  in  sustainable  development  across  the  business, 
offering up to 50% carbon reduction on all standard blocks 
produced  at  CCP  Building  Products.  This  has  saved  over 
6,000  tonnes  of  CO2  since  its  introduction  and  has  been 
offered at no additional cost to the customer. CCP completed 
its  expanded  new  ranges  by  introducing  an  additional 
premium  range  product,  which  sits  between  its  standard 
50% reduction product and ultra cement-free and provides 
up to a 70% carbon reduction at a competitive price.

Greenbloc  can  now  be  incorporated  in  almost  all  of  our 
concrete  products,  available  in  three  distinct  performance 
levels.  These  levels  provide  a  range  of  embodied  CO2 
reductions from 50% to 90%. Greenbloc is a flexible solution, 
enabling  daily  production  and  the  ability  to  turn  cement-
free  concrete  on-and-off  for  environmentally  significant 
bespoke  projects.  These  include  the  UK  Environmental 
Agency’s  Canvey  Island  Sea  Defence  and  Jimmy’s  Farm 
Polar Bear Relocation projects, both of which achieved over 
80%  reduction  in  the  carbon  embodiment  of  the  concrete 

products. As a  result  of these initiatives, we have  become 
one  of  the  leading  UK  producers  of  cement-free  pre-cast 
concrete,  producing  more  wet-cast  cement-free  concrete 
per day than any other precast company, and underscoring 
the  industry’s  shift  towards  more  sustainable  practices. 
The  resulting  media  focus  has  brought  more  cement-free 
projects to the business for 2024. Looking ahead, we aim to 
surpass the 100% mark, positioning ourselves as pioneers 
in producing large-scale negative carbon concrete products. 

A leap in innovation was gained through the production of a 
carbon-negative-cement-free concrete block, which boasted 
a 115% carbon reduction and was created using Greenbloc 
cement-free  technology,  combined  with  carbon-negative 
aggregate  produced  from  waste  materials  and  captured 
carbon. The block showed all the same characteristics and 
performance as standard equivalent cement-based blocks 
and is expected to become part of an extended future range 
with the introduction of Mevo at CCP in 2024.

MTech

SigmaRoc  has  produced  an  in-house  cement-free-carbon-
in 
negative  concrete  with  patentable  opportunities, 
collaboration with Marshalls. The concrete combines carbon-
negative  materials  with  an  in-house  developed  cement-free 
binder which incorporates upcycled waste lime kiln dust from 
Nordkalk.  The  patent  application  will  be  submitted  in  2024 
with expected opportunities for use in 2025.

Puccini Blue

Developed  by  John  Vis  (Commercial  Director  of  Carrieres 
du  Hainaut)  and  Chris  Vermorken  (Legal  and  Operational 
Advisor) with the help of Elisa Frenay (Group Marketing Lead), 
Puccini Blue is a revolutionary new way to maximise quarry 
yield by making the fault lines of products a distinctive and 
highly  desirable  feature  through  resin  technology.  Material 
that once had to be separated due to natural fault lines and 
therefore  producing  less  yield,  can  now  be  processed  to 
ensure structural integrity of the fault lines to maximise not 
only the yield, but the aesthetic product offering so desirable 
to our customers.

Nordkalk Next

A product offering where at least 33% of the material used 
is reusable material, own or external, that is not used or is 
considered waste. Further, 33% of energy used in production 
is fossil free. This is considered as per energy content. 

Nordkalk Complete

A  product  offering  where  100%  of  the  material  used  is 
material, own or external, that is not used or is considered 
waste. CO2 neutral scope 1 and scope 2.

Sustainable Products

We  are  proud  to  be  working  in  collaboration  with  a  series 
of  partners  on  the  development  of  products  that  promote 
sustainability, such as the EcoTile, that creates spaces within 
the fabric of our cities and towns in which multiple species 
can  survive  and  thrive,  and  where  humans  can  interact 
and  engage  safely  with  nature.  Initial  trials  showed  that  a 
multitude  of  species  settled  where  they  were  expected  to, 
and in the design features – the multispecies design works.

In 2023, Nordkalk introduced seven innovative, sustainable 
products  and  solutions  across  a  diverse  range  of 
applications. A brand-new range of fossil-free products was 
launched in Ignaberga, Sweden, marking a significant step 
forward  in  the  company's  commitment  to  sustainability. 
Additionally,  more  efficient  soil  improvement  products 
specifically  designed 
for  agricultural  purposes  were 
developed  for  the  Swedish  market.  In  the  construction 
sector,  Nordkalk  developed  two  novel  fillers:  an  ultrafine 
product aimed at reducing the use of cement and additives 
in plasters, and another product designed to minimise the 
bitumen content in roofing materials. 

Our People and PepTalk

The  way  in  which  companies  measure  the  “S”  in  ESG 
or  their  social  impact  has  a  significant  effect  on  the 
wellbeing of their employees, the wider community and the 
organisation's stakeholders. The significance of measuring 
and  reporting  social  risks  and  impacts  is  underscored  by 
the  presence  of  social  inequalities  and  the  necessity  for  a 
transition  to  a  sustainable  economy.  Prioritising  employee 
wellbeing  and  the  internal  culture  of  organisations  is 
becoming increasingly important in today’s society and are 
essential metrics for the “S” in the ESG strategy as employee 
wellbeing is central to an organisation’s social performance.

In  2023  SigmaRoc  incorporated  PepTalk  into  its  UK  ESG 
strategy  to  enhance  employee  engagement  and  well-
being.  PepTalk  provides  a  data-led  engagement  platform 
to improve psychological safety, enhance employee morale 
and reduce attrition. The integration of PepTalk aligns with 

111

their  commitment  to  enhancing  employee  wellbeing  and 
contributes to a positive corporate culture.

PepTalk  supports  our  Social  Responsibility  strategy  as 
follows:

• 

• 

• 

• 

Employee  Wellbeing:  providing  a  safe, 
inclusive 
workplace and offering a tool such as PepTalk’s platform 
and program that can help in delivering regular training 
and  development  opportunities  to  foster  professional 
growth.

Employee  Satisfaction  &  Feedback:  measurement  of 
employee  satisfaction  and  the  success  of  wellbeing 
initiatives.

100%  reach:  modern  technology  enables  a  dispersed 
team to stay connected through a wide range of content-
led  program  and  actions  plans  that  are  designed  to 
support team connection and engagement. 

Expert-led  Wellbeing  and  Culture  Calendar:  rolling 
wellbeing  and  culture  content  calendar,  designed  in 
partnership  with  industry experts and thought leaders 
that enables employees to perform at their best. 

•  Team  Building  Initiatives:  customised  competitions 
across wellness and activity designed to drive employee 
connection and collaboration.

• 

• 

• 

Scope  1  –  commissioning  of  the  Company’s  first 
modular Carbon Capture system

Scope  2  –  improvement  of  energy  use  and  energy 
intensity and sourcing of alternative energy

Scope  3  –  continual  development  of  sustainable 
products

The commissioning of the Company’s first modular Carbon 
Capture system and continual development of sustainable 
products helping recue scope 1 and scope 3 emission. The 
modular  plant  is  now  commissioned  and  able  to  capture 
with a purity of 96% through just 2 stages. Subject to finding 
a commercial outlet for the CO2, the Company is in a position 
to  expand  the  roll  out  of  the  system.  Whilst  Governments 
and  third  parties  continue  to  try  to  develop  necessary 
policies  and  infrastructure  for  transport  and  sequestration 
of CO2, the Company is proactively identifying independent 
transportation systems that can utilise road and rail as well 
as internal and external CO2 uses such as the sequestration 
of CO2 into our own concrete products to support Greenbloc 
and Mevo technology.  

The  Company  has  engaged  with  a  series  of  mandatory 
and  voluntary  programmes  to  focus  on  the  reduction  of 
emissions  intensities.  These  include  reporting  to  CDP  as 
well  as  submission  to  SBTi  of  which  we  are  awaiting  the 
verification process.

Additional initiatives include completion of our ESOS report 
which  is  part  of  the  European  Energy  Directive  and  the 
submission  of  our  annual  SECR  report  that  looks  at  both 
mandatory and voluntary reporting aspects and is a guide 
to focus areas.

Toxic Emissions and Waste

Governance and Strategy

Environmental  Management  Systems  (EMS)  are  key  to 
ensuring management of toxic emissions and waste. Across 
our  businesses,  76%  of  our  businesses  (by  revenue)  have 
an ISO14001 certified Environmental Management System 
(EMS) that also include provisions for waste management 
with no fines being incurred in 2023.

Our  EMSs,  including  our  14001  audited  EMS  are  regularly 
audited by external auditors as well as additional specialised 
audits conducted by the likes of MCA and Lloyds Register 
for aspects such as MARPOL (the International Convention 
for the Prevention of Pollution from Ships.)

Targets & Performance

In terms of air quality, our NOx and SOx performance has seen 
a significant step change reduction. This has been achieved 
through a combination of kiln network balancing and the use 
of Selective Non Catalytic Reduction (SNCR) systems.

Energy and Climate Policy

These include provisions and commitments on sustainably 
managing natural resources and raw materials, minimising 
disturbance  from  operations  and  reclaiming  habitat  and 
disturbed land.

The  Board  has  overall  responsibility  for  the  Policies  and 
approves the policies which are then cascaded throughout 
the business with a formal acknowledgement and training 
program  to  be  rolled  out  in  2024  to  all  employees  and 
contractors as required. These will be monitored and audited 
quarterly by the Board with a target of 100% compliance for 
employees in terms of acknowledgement and training.

Program and Structures

Restoration and Rehabilitation

As  part  of  site  planning  and  permits,  most  government 
agencies  and  authorities  require  restoration  plans  to  be  in 
place. These restoration plans cannot be completed until the 
operations have come to end of life, however where there is 
an opportunity, our sites work concurrently to restore areas 
that are no longer operational. 

Despite  the  Group  operating  over  a 
large  area  of 
approximately 5,287 acres, with 17% having been restored 
or  under  restoration  restored  in  line  with  local  authorities 
and community requirements. 

Protection of natural ecosystems

Even before a point of final restoration, our sites work closely 
with local authorities, working groups and communities to 
ensure  we  maximise  not  only  the  preservation  of  existing 
ecosystems, but often the generation of further eco-systems 
to  provide  a  thriving  environment  for  existing  species  but 
also  previously  extinct  species.  This  includes  both  fauna 
and  flora  with  success  derived  through  programs  such  as 
flora  relocation  programmes,  wildflower  programs,  Red 
Bill  chough  breeding  programs,  Peregrine  falcon  nesting 
programs and great crested newt habitat establishment.  

Some sites are close to Sites of Specific Scientific Interest 
where  our  working  relationships  with  local  groups  and 
national  agencies  have  helped  ensure  they  thrive.  Where 
there  is  risk  of  impact,  the  valuable  species  are  moved  to 
other suitable or created areas.

Biodiversity and Community Impact

The  Company  works  closely  with  communities  and  local 
authorities to ensure that our ongoing operations and future 
operations minimise environmental and community impact. 
Our  future  works  are  supported  by  impact  assessments 
prior to the commencement of work.

Operational considerations not only seek to minimise impact, 
but also actively enhance biodiversity in surrounding areas.

Before  commencing  operation  of  a  site,  the  potential 
environmental, including bio diversity, and social impacts are

Overview

Operating  in  numerous  countries  across  the  UK  and 
Europe,  we  continue  to  ensure  compliance  with  local 
regulation,  which  is  managed  at  a  local  level,  whilst  at 
the  same  time  integrating  these  businesses  to  align  with 
best  practice  Group  H&S  standards.  We  are  committed 
ensuring  awareness  about  H&S  issues;  reducing  the 
number  of  severity  of  accidents;  preventing  occupational 
disease; promoting wellbeing and preventing exposure to 
hazardous substances.

STRATEGIC REPORTSIGMAROC ANNUAL REPORT 2023115

The  Group  also  maintains  a  strong  focus  on  conducting 
detailed investigations, not only after an event has happened, 
but also before events happen. For example, through Bow 
Tie  analysis,  core  risk  events  can  be  reviewed  before  they 
happen.  This  allows  causes  to  be  proactively  identified 
so  safety  barriers  can  be  implemented  to  mitigate  routes 
to  an  adverse  H&S  event.  On  the  flip  side,  the  effects  and 
consequences of the event are also proactively identified so 
safety barriers can be implemented to mitigate the impacts 
of such an event. 

Post  event  investigation,  including  investigation  on  near 
hits, and externally publicised events both in our industry 
and  beyond,  is  conducted.  The  level  of  investigation 
is  proportional  to  the  severity  and  seeks  to  review  not 
just  the  event,  but  also  organisation  factors,  task  and 
environmental conditions, individual and team actions and 
absent or failed defences. 

It is by these principles and through core risk management 
and  investigation  that  the  Group  can  act  to  continually 
deliver its year-on-year H&S improvement.

Clint  
White

HSE&P  
DIRECTOR

Principles

The Group continues to drive its overarching H&S standards 
which  we  believe  supported  the  continual  improvement  in 
health and safety in 2024.

Core Risks

The Company continues to focus on its core risks:

Entrapment by machinery / moving parts

•  Contact with moving vehicles / objects
• 
•  Hit by suspended load / falling objects
• 
• 
•  Powders and COSHH material handling

Trapped by significant mass / energy

Falls from height

Two primary areas of focus that have improved our control 
of core risks have been:

1. Serious Injury or Fatality (SIF) framework; and

2. Investigations.

Front line leadership

SIF is the focus on events that could lead to Serious Injury 
or Fatality; in simple terms those events that cause or have 
the  potential  to  cause  life  threatening  /  changing  injuries. 
This work has been heavily developed in recent times and 
is seen to be the next evolution of well-grounded traditional 
H&S principles; driving the focus to those areas that are of 
the most serious nature. This has supported and aligns with 
our core risks and enables us to develop improved reporting 
to ensure action on those key areas.

We continue focus on front line leadership, with learning and 
development supported by programs such as NEBOSH and 
IOSH training for supervisor and front-line management. 

Our  boots  on  the  ground  program  has  been  a  significant 
contributor to our ongoing health and safety success. Front-
line  leaders  are  more  visible  in  the  business  ensuring  a 
continued improvement in the output of not only safety, but 
also quality and productivity.

Our ESG Journey

HighVizz

HighVizz  continues  to  be  continually  developed  and 
integrated into  our  newly  acquired  businesses  allowing  us 
dynamically to report and manage safety. HighVizz includes 
SIF identification, as well as new modules such as pre-start 
inspections, and enables our teams to have lean processes 
and systems that ensure risks are managed more effectively 
and efficiently.

Occupational Health

Both SASB and the UK Minerals Product Association have 
a  focus  on  occupational  health,  especially  Silicosis.  As  a 
Group  we  have  a  hierarchy  of  controls,  based  upon  best 
health  and  safety  guidance  and  an  assessment  of  the 
risks within our sites and workplaces ensuring compliance 
with  HASWA  1974,  MHSWR  1999,  COSHH  Regulations, 
L140 – HSE ACOP for HAVS, PUWER 1998, HSG258 – HSE 
Controlling  airborne  contaminants  at  work  (use  of  LEVs) 
and EH75-4 and INDG 463 Silica and control methods.

These include:

•  Use of Risk assessments, safe systems of works and 

COSHH assessments;

•  Minimising  dust  generated  by  our  operations  through 
engineering  controls  such  as  enclosing  processing 
equipment  and  transfer  points,  water  suppression, 
use of spray systems for dust encapsulation and local 
exhaust ventilation;

•  Periodic  personal  and  local  monitoring  by  external 
consultants  and  subsequent  personal  assessments 
against recognised exposure limits;

•  Health  questionnaires  and  health  surveillance  of  staff 

by Occupational Health specialists;

•  Where  surveys 

identify  potential  exposure  above 
recognised exposure limits warning signage is posted 
and workers are required to wear appropriate respiratory 
protective equipment including full and half masks, and 
air fed breathing systems;

• 

• 

• 

Time limits set for and policy of job rotation to minimise 
exposure times in addition to the use of specialised PPE 
in areas of risk;

Training  for  new  employees  and  regular  refresher 
training  for  existing  employees  to  raise  awareness  of 
the risks to health that can arise from exposure; and

Training  in  the  correct  use  and  maintenance  of  PPE 
provided to protect their health and other checks such 
as face fit testing for dust masks.

Governance and strategy

the  Company’s  operations  are  certified 

69%  of 
to 
ISO18001/45001.  Those  that  are  not,  leverage  the  safety 
management systems.

In  addition  to  safety  management  systems,  the  Group 
operates  its  own  internal  audit  function  with  over  172 
internal  audits  conducted  in  2023  across  our  operations. 
The audits focus on both systems and sites, with interactive 

and constructive feedback and actions generated. The audit 
also monitors the close out of these actions.

Responsibility

The  Board  has  overall  responsibility  for  Health  and  Safety 
with  the  implementation  of  the  strategy  and  performance 
managed  by  the  Group  Health  &  Safety  committee  that 
has  both  Executive  Directors,  Non-Executive  Directors  and 
Executive  Committee  members  as  part  of  the  committee. 
The  delivery  of  the  strategy  and  driving  of  performance  is 
then the directive of the Group Health & Safety Director.

Once the Health & Safety strategy is set by the Board and 
Group HS Committee, the Executive Committee and Health 
&  Safety  Director  implement  the  strategy  and  drive  the 
performance.  Each  month  the  performance  is  reviewed 
by  the  executive  management  committee  in  a  dedicated 
meeting and is cascaded wider to ensure that all employees 
are  engaged.  Health  and  safety  form  a  key  part  of  every 
Board and Executive meeting.

HS Policy

The Company operates a Group wide Health & Safety Policy 
that  is  cascaded  and  implemented  in  every  business. The 
Policy applies to any person operating on our sites, including 
employees, contractors and visitors.

The  policy 
is  approved  by  the  Board  and  cascaded 
throughout  the  business  with  a  formal  acknowledgement 
and training program to be rolled out in 2024 to all employees 
and  contractors  as  required.  These  will  be  monitored 
and  audited  quarterly  by  the  Board  with  a  target  of  100% 
compliance  for  employees  in  terms  of  acknowledgement 
and training.

H&S Targets and Performance

The group is committed to the continuous improvement of 
health  and  safety  and  wellbeing  for  any  person  who  is  on 
our site, be it an employee, contractor or visitor.

2023 the Group employed c.2000 people.

Within the heavy materials industry, diversity continues be a 
challenge especially at an operational level with 80% of our 
workforce  being  at  an  operational  level.  Across  the  Group 
12% of our work force is female, however 42% of our shared 
services and management is female.

We continue to engage with school leavers and apprentices 
to  ensure  there  is  succession  planning  and  that  the 
knowledge of our long serving employees is retained within 
the business with our overall age profile as follows:

This  development  of  our  teams  has  been  supported  by 
>22,000 hours of learning and development that has been 
delivered during the course of 2023.

In addition to the recruitment of staff to support our growing 
businesses,  we  also  review  employee  retention  through 
aspects such as local satisfaction surveys, training, career 
management plans and performance reviews.

The Group has not experienced any strikes / lockouts within 
its businesses in the last three years.

Strategy

Each OPCO is responsible for the recruitment, management, 
and  retention  of  its  employees  with  renumeration  policies 
being guided by local legislation. Generally, Supervisors and 
managers have a variable component to their renumeration 
which is based on a combination of business performance 
as  well  as  personal  performance  and  operators  have  a 
variable component to their renumeration which is usually 
based on operation and site performance. 

Each business complies with its jurisdictional requirements 
around  aspects  such  as  pensions  and  where  applicable  / 
available  offers  additional  non-compensation  employee 
benefits such as life assurance and medical insurance that 
can  often  be  extended  to  employees’  families,  allowing 
them access to preferential rates.

UK ENERGY USE AND ASSOCIATED GREENHOUSE GAS 
EMISSIONS

Current  UK  based  annual  energy  usage  and  associated 
annual  greenhouse  gas  (“GHG”)  emissions  are  reported 
pursuant 
(Directors’  Report)  and 
Limited  Liability  Partnerships  (Energy  and  Carbon  Report) 
Regulations  2018  (“the  2018  Regulations”)  that  came  into 
force 1 April 2019. 

the  Companies 

to 

ORGANISATIONAL BOUNDARY

Energy  use  and  associated  GHG  emissions  are  reported 
across  the  Group  as  defined  by  the  operational  control 
approach.  This  includes  operations  in  the  UK,  Channel 
Islands  (‘North  West’),  Belgium  (‘West’)  and  across  Estonia, 
Finland, Poland, Sweden, Turkey & Spain (‘North East’). This 
exceeds the minimum mandatory requirements set out in the 
2018 Regulations for ‘large unquoted companies’, which only 
require reporting of UK based energy use and emissions.

REPORTING PERIOD

The  annual  reporting  period  is  1st  January  to  31st 
December each year and the energy and carbon emissions 
are aligned to this period. 

QUANTIFICATION AND REPORTING METHODOLOGY

The  data  was  prepared  with  reference  to  the  2019  UK 
Government  Environmental  Reporting  Guidelines  and  the 

GHG Protocol Corporate Accounting and Reporting Standard 
(revised  edition).  Emissions  calculations  were  based  on 
emission  factors  published  in  the  2023  UK  Government 
GHG Conversion Factors for Company Reporting, Statistics 
Finland  Fuel  Classification  2023,  Swedish  Environmental 
Protection  Agency  Emission  Factors  2022,  and  the  latest 
available  factors  from  the  Association  of  Issuing  Bodies 
(2022),  Jersey  Electricity  and  Guernsey  Electricity.  The 
report has been reviewed independently by Briar Consulting 
Engineers  Limited.  Electricity  and  gas  consumption  were 
based on invoice records, consumption data and estimation 
techniques  such  as  the  direct  comparison  and  pro-rata 
extrapolation  to  complete  missing  data.  Transport  usage 
was  calculated  from  a  combination  of  mileage  and  fuel 
records;  however,  outside  the  UK  and  Channel  Islands, 
transport  fuel  is  included  with  other  site  fuel  usage 
associated  with  stationary  assets.  Gross  calorific  values 
were  used  except  for  mileage  energy  calculations  as  per 
Government GHG Conversion Factors.

The  emissions  are  divided  into  mandatory  and  voluntary 
emissions  according  to  the  2018  Regulations,  then 
further  divided  into  the  direct  combustion  of  fuels  and 
the  operation  of  facilities  (scope  1),  indirect  emissions 
from  purchased  electricity  (scope  2)  and  further  indirect 
emissions  that  occur  as  a  consequence  of  company 
activities but occur from sources not owned or controlled 
by the organisation (scope 3).

INTENSITY RATIO

The  intensity  ratio  is  total  gross  emissions  in  metric  tonnes 
CO2e per total million-pound (£m) turnover. This is calculated 
separately  for  ‘mandatory’  emissions  and  ‘mandatory  & 
voluntary’  emissions  for  the  UK  and  regionally  for  the  North 
West, West and North East SigmaRoc Regions. This financial 
metric is considered the most relevant to the Company’s wide-
ranging  activities  and  allows  a  comparison  of  performance 
across other organisations and sectors.

ENERGY EFFICIENCY ACTION DURING CURRENT 
FINANCIAL YEAR

Emissions in the North East have seen a 7.5% (51,005 tCO2e) 
decrease  in  2023  compared  to  2022.  A  large  share  of  this 
decrease  is  due  to  the  further  transition  away  from  coal  to 
alternative fuel sources such as recycled fuel oil and biomass.  

In St John, Jersey, a new solar PV array was commissioned 
in April 2023. This investment by Jersey Electric will benefit 
Ronez  by  saving  approximately  57  MWh  each  year.  Ronez 

has continued to experiment with low temperature asphalt by 
switching to Nytherm during the reporting period to reduce 
gas  oil  usage  by  approximately  55,500  litres.  Furthermore, 
the addition of 3 EV’s to the company fleet (including 2 plug-
in  hybrids)  will  reduce  diesel  and  petrol  consumption  and 
therefore  reduce  emissions  associated  with  transport.  At 
Carrières du Hainaut, there was an extension of the existing 
photovoltaic  park  by  increasing  the  existing  surface  area 
by  approximately  57%.  This  installation  aims  to  send  62% 
of  the  electricity  generated  to  the  Carrières  site  for  self-
consumption,  with  the  surplus  sent  into  the  ORES  public 
network. The project includes the installation of a total power 
of  1,999,215  kWp  from  a  total  of  2,889  panels.  Gross  UK 
emissions  have  decreased  by  7.0  %  (1,075  tCO2e)  in  2023. 
This is largely due to the significant reduction in emissions by 
company owned vehicles and site fuel (1,112 tCO2e) across 
sites  within  the  UK.  In  particular,  kerosene  consumption  at 
Bolton  Hill  Quarry  decreased  by  1.78  GWh  (442.3  tCO2e)  in 
2023, contributing to nearly half of the decrease in company 
vehicle and site fuel emissions.

TCFD Report

The  Board  has  noted  the  new  requirement  for  mandatory  climate-related  disclosures  
arising from the Companies (Strategic Report) (Climate-related Financial Disclosure) Regulations 
2022.  Consequently,  we  provide  disclosures  aligned  with  the  recommendations  issued  by  the 
Task  Force  on  Climate-related  Financial  Disclosures  (TCFD)  in  this  Annual  Report  for  the  year 
ended 31 December 2023. 

125

This  report  is  based  on  the  TCFD  recommendations  and 
recommended disclosures as detailed in Recommendations 
of the Task Force on Climate-related Financial Disclosures 
(2017),  considering  the  additional  guidance  set  out  in  the 
TCFD 2021 Annex, ‘Implementing the Recommendations of 
the Task Force on Climate-related Financial Disclosures’.

We recognise that climate change presents both material risks 
and  opportunities  to  our  business  and  sector.  Accordingly, 
the  following  report  covers  the  Group’s  well-established 
governance  of  climate  change  issues,  its  integration  into 
our  overall  risk  management  processes,  our  strategies 
for  managing  climate-related  risks  and  opportunities,  and 
relevant  metrics  used  to  measure  progress  towards  our 
climate targets. We have prepared this report with the support 
of  external  sustainability  consultants,  CEN-ESG,  who  have 
enhanced  the  analysis  of  our  exposure  to  natural  hazards 
with  a  detailed  bottom-up  site  analysis  using  a  geospatial 
climate hazard mapping tool.

This report is based on the structures and operations in place 
on 31 December 2023. Given the agreement with CRH plc to 
acquire its European lime operations, we have decided that 
any  detailed  quantification  of  our  key  climate-related  risks 
and  opportunities  will  be  published  in  next  year’s  annual 
report  to  accommodate  the  significant  transformation  to 
the business from the acquisition.

GOVERNANCE

Board level

At  SigmaRoc,  climate-related  governance  has  been 
well-integrated  for  several  years.  The  Board  has  overall 
responsibility  for  sustainability  issues  including  climate-
related  matters,  and  effective  management  of  climate-
related  risks  and  opportunities  as  with  all  matters  of 
Group  strategy.  The  Board  meets  quarterly,  and  ESG, 
including  climate-change,  is  a  standing  agenda  item  at  all 
these  meetings,  with  updates  on  climate-related  issues 
presented  by  the  Chief  Technical  Officer  (CTO)  who  sits 
as a permanent guest at board meetings. Additionally, the 
Board  considers  climate-related  issues,  especially  CO2 
emissions,  when  reviewing  and  guiding  strategy,  major 
plans  of  action,  policies,  annual  budgets,  and  business 
plans  as  well  as  setting  the  organisation’s  performance 
objectives,  monitoring  implementation  and  performance, 
and  overseeing  major  capital  expenditures,  acquisitions, 
and  divestiture.  The  Board  is  supported  by  committees 
including the Audit Committee, which assists in monitoring 
ESG performance and climate-related risks.

In  2023,  the  development  of  science-based  targets  and 
the  Road  Map  to  Net  Zero  has  been  a  particular  focus 
of  Board  meetings,  and  now  drives  the  management  of 
climate-related  risks  and  opportunities  through  review  of 
carbon  emissions. The  Board  is  responsible  for  approving 
TCFD  disclosures  and  is  also  responsible  for  reviewing 

and  signing  off  the  risk  register,  including  risks  related 
to  the  environment  and  climate  change.  The  Board  does 
not  currently  receive  formal  training  from  third  parties  on 
climate-related issues, but receives information provided by 
the CTO and other members of the Group when required.

To  ensure  appropriate  visibility  over  climate  change  is 
maintained  as  operations  continue  to  expand,  in  2024 
SigmaRoc will seek to appoint a new non-executive director 
with a strong background in ESG and climate change.

Furthermore, a dedicated ESG Committee has been formed, 
including Independent Board and Executive Board members 
and the CTO, who will meet throughout the year when the 
quarterly ESG & Climate Change Working Group Report will 
be presented.

Management level

At  the  direction  of  the  Board,  the  Chief  Technical  Officer 
is assigned responsibility to assess, monitor and manage 
climate-related  risks  and  opportunities  alongside  Group-
level  risk  management.  The  Executive  Committee  meets 
monthly  and  the  CTO  is  responsible  for  updating  the 
issues  and  other  ESG 
Committee  on  climate-related 
initiatives.  The  CTO  is  informed  via  ongoing  dialogue 
with  the  managing  directors  from  each  of  the  business 
units,  who  monitor  and  report  on  general  risks,  strategic 
projects  and  operations,  including  climate-related  issues, 
as necessary.

Each  business  unit  is  also  responsible  for  monitoring  and 
feeding back the key aspects to be reported as defined by 
permits,  legislation  and  frameworks.  Data  collection  and 
monitoring is done through online process control systems, 
purchase  orders,  consumption  meters  etc.  This  includes 
statutory  (e.g  NOx  and  SOx),  and  non-statutory  aspects 
such  as  land,  power  and  water  use.  The  data  is  collated 
through group wide tools such as OneClick LCA.

Following the recent agreement to acquire CRH’s European 
lime  business,  SigmaRoc  is  currently  recruiting  a  Group 
Sustainability Manager who will be responsible for collating 
climate and ESG data, monitoring performance, overseeing 
climate-related projects, and educating across the Group on 
climate-related  issues.  The  Group  Sustainability  Manager 
will also create and lead an ESG & Climate Change Working 
Group  with  representatives  across  all  operational  regions, 
who will meet quarterly to review progress across the Group, 
and  subsequently  prepare  and  provide  quarterly  updates 
and reports to the Board and ESG Committee.

RISK MANAGEMENT

Climate-related  risks  are  integrated  into  SigmaRoc’s  risk 
management  processes  and  are  considered  as  part  of 
the  overall  Group  risk  management  processes.  The  risk 
assessment considered existing and emerging risks and all 
risk  categories  outlined  in  the  TCFD  recommendations  in 
relation to all of SigmaRoc’s operations as of 31 December 
2023.  Climate-related  risks  and  opportunities  were  also 
considered across upstream and downstream supply chains.

Climate-related risk identification is performed both bottom-
up,  through  a  detailed  assessment  of  risks  affecting 
each  individual  site,  and  top-down,  through  a  high-level 
assessment of strategic, transition and market risks pertinent 
to  the  Group  and  its  sector.  Additionally,  risks  are  identified 
through discussion and engagement with primary investors, 
peer review and through a cross-functional process led by the 
CTO taking into account internal stakeholders such as H&S, 
ESG, Estates and the General Counsel.

Site-level  environmental  risks,  including  climate  change 
risks, are identified as part of operational risk assessments. 
These are conducted at a plant level and reviewed, assessed 
and  monitored  by  regional  Environmental  and  Industrial 
Direct  teams.  This  year,  the  Group  enhanced  its  site-level 
assessment  of  both  chronic  and  acute  physical  climate-
related risks using geospatial modelling software, which has 
provided greater detail and specificity for each individual site 
in  the  Group’s  portfolio.  Where  material  risks  are  identified, 
risk assessments are reviewed at divisional and Group level. 
Once 
identified,  climate-related  risks  and  opportunities 
are  assessed  and  scored  according  to  their  likelihood  and 
impact,  in  order  to  assess  their  relative  magnitude  relative 
to  other  risks.  Impact  is  assessed  based  on  quantitative 
and  qualitative  or  reputational  and  financial  risk  according 
to  the  standard  risk  management  thresholds.  Likelihood  is 
assessed based on the following thresholds:

three  climate-related  scenarios  were 
examined,  looking  forward  out  to  2100,  to  identify  and 
assess physical climate-related risks.

•  RCP 2.6: a climate-positive pathway, likely to keep global 
temperature  rise  below  2  °C  by  2100.  CO2  emissions 
start declining by 2020 and go to zero by 2100. 

•  RCP 4.5: an intermediate and probably baseline scenario 
more likely than not to result in global temperature rise 
between 2 °C and 3 °C, by 2100 with a mean sea level 
rise  35%  higher  than  that  of  RCP  2.6.  Many  plant  and 
animal species will be unable to adapt to the effects of 
RCP 4.5 and higher RCPs. Emissions peak around 2040, 
then decline.

•  RCP 8.5: a bad case scenario where global temperatures 
rise between 4.1-4.8°C by 2100. This scenario is included 
for its extreme impacts on physical climate risks as the 
global response to mitigating climate change is limited. 

The following two climate-related scenarios were examined, 
looking  forward  out  to  2050,  to  identify  and  assess  the 
behaviour of transition risks and opportunities.

•  Net  Zero  2050  (NZE):  an  ambitious  scenario  which 
sets out a narrow but achievable pathway for the global 
energy  sector  to  achieve  net  zero  CO2  emissions  by 
2050.  This  meets  the  TCFD  requirement  of  using  a 
“below 2°C” scenario and is included as it informs the 
decarbonisation pathways used by the Science Based 
Targets  initiative  (SBTi),  which  validates  corporate  net 
zero targets and ambition.

•  Stated  Policies  Scenario  (STEPS):  a  scenario  which 
represents the roll forward of already announced policy 
measures.  This  scenario  outlines  a  combination  of 
physical  and  transitions  risk  impacts  as  temperatures 

rise by around 2.5°C by 2100 from pre-industrial levels, 
with  a  50%  probability.  This  scenario  is  included  as 
it  represents  a  base  case  pathway  with  a  trajectory 
implied by today’s policy settings.

Over  2024  SigmaRoc  will  be  restructuring  the  business  in 
order  to  integrate  appropriately  the  newly  acquired  sites 
into  the  risk  management  process.  Once  appointed,  the 
Group  Sustainability  Manager  will  collect  data  relating 
to  environmental  and  climate-related  risks  as  part  of  the 
quarterly  review,  maintain  a  central  register  and  prepare  a 
suite of reports to be reviewed by the Group ESG committee. 

STRATEGY

Having  assessed  the  climate-related  hazards  affecting 
the entire estate, SigmaRoc’s overall exposure to physical 
climate-related risks is considered to be low. By contrast, 
as a supplier of both low and high grade materials for use 
in  construction,  agriculture,  environmental  and  industrial 
applications, SigmaRoc’s exposure to transition risks may 
be greater due to developing environmental regulation and 
stakeholder  expectations  in  Europe.  Nevertheless,  given 
the  longstanding  work  to  identify  and  mitigate  climate 
impacts  on  the  Group,  the  strategy  is  considered  to  be 
resilient  to  climate  risks  and  opportunities.  As  detailed 
against  each  risk,  SigmaRoc  is  working  to  decarbonise 
its  operations  through  energy  efficiency,  transition  to 
renewable  electricity,  the  development  of  carbon  capture 
mechanisms  and  via  strategic  collaboration  to  minimise 
exposure  such  that  any  strategic  and  financial  impacts 
from  climate  change  are  limited.  Moreover,  SigmaRoc 
considers  itself  at  the  forefront  of  the  green  transition 
by  providing  the  materials  that  are  essential  to  the  green 
economy and will be enhancing its strategy to capitalise on 
these opportunities in the coming years.

1. Disruption due to fluvial or coastal flooding

Following  an  assessment  of  climate-related  hazards 
affecting  the  Group’s  portfolio,  flood  risk  exposure  from 
rivers and sea level rise was identified for several sites.

While 92% of the portfolio is at minimal risk of river flooding, 
7 sites are currently in the highest flood risk zone and will 
remain  in  this  risk  bracket  under  all  future  scenarios  and 
time horizons. Flooding is likely SigmaRoc’s most material 
physical  risk  at  present  due  to  its  potential  to  destabilise 
assets.

Sea  level  rise  is  a  growing  risk,  with  7  sites  at  medium  or 
high  risk  under  RCP  2.6  and  4.5.  Under  a  severe  RCP  8.5 
scenario, 7 of these sites would be exposed to high risk, with 
the final site exposed to extreme risk. 

Mitigation

Mitigation  of  hydrological  risks  in  some  operations  is 
already  business  as  usual.  Whereas  some  sites  naturally 
drain and consequently remain dry, others require periodic 
de-watering.  Historically  the  Group  has  found  that  water 
logging  does  not  tend  to  stop  operations  altogether  at  an 

STRATEGIC REPORTSIGMAROC ANNUAL REPORT 2023affected quarry, as work can be diverted to a different area 
of the quarry whilst groundwater is pumped away.

Even  in  the  event  of  downtime  at  a  particular  quarry, 
SigmaRoc has the capacity to rebalance activities across the 
network and therefore recoup any costs lost, admitting some 
transfer  costs.  Redundancy  in  stock  is  maintained  across 
quarries, which could also remediate any downtime losses. 
All sites exposed to a medium/high risk of sea level rise are 
able to divert resources to alternative sites in the event of a 
storm surge event. None of the sites identified as being at risk 
of river flooding are material in terms of financial risk.

In  addition,  the  geospatial  analysis  only  models  regional 
flood  defences  at  a  handful  of  countries,  so  SigmaRoc’s 
risk exposure may be lower than indicated due to flood and 
storm defences that have not been accounted for. Further, 
sea  level  rise  is  likely  only  to  materialise  in  the  very  long 
term  and  could  therefore  fall  outside  reasonable  business 
planning horizons.

2. Carbon pricing within operations

The  scope  of  carbon  pricing  (applied  directly  or  indirectly) 
is expected to expand over the medium term, and the price 
of carbon is expected to rise. SigmaRoc is already exposed 
to the EU Emissions Trading Scheme (ETS), although does 
not  fall  under  the  Carbon  Border  Adjustment  Mechanism 
(CBAM)  so  the  loss  of  free  allocation  by  2035  is  less 
substantial than in other adjacent sectors, namely cement.

limitations  on 

in  scope  3  emissions  given 

Given the nature of the sector, SigmaRoc is a large emitter 
its  ability  to  decarbonise, 
with  greater 
especially 
its  supply  to 
customers  with  high  emissions.  Some  operations  will  be 
particularly  challenging  to  decarbonise,  while  machinery 
can  be  replaced  with  more  efficient  and  cleaner  models, 
substantial  emissions  (approximately  70-80%)  arise  from 
the chemical reactions within kilns.

Mitigation

SigmaRoc  is  focused  on  the  transition  from  fossil  fuels 
to  fossil  free  energy  and  biofuel,  and  improvements  in 
operational efficiency such as efforts to reduce machinery 
idle time. The Group continues to install renewable energy 
capacity on site, upgrade its vehicle fleet, conduct heat and 
power loss reviews of large assets, expand carbon capture, 
utilisation and storage (CCUS) infrastructure, and purchase 
PPAs.  Capital  expenditure  to  decarbonise  operations, 
including  the  replacement of  higher-emitting  machinery,  is 
largely covered by business-as-usual expenditure.

In addition, SigmaRoc is able to pass on costs related to ETS 
credits  through  to  customers  in  contracts.  Addressing  the 
challenge posed by chemical reactions in kilns is an ongoing 
challenge  requiring  further  research  and  development.  In 
the meantime, costs related to kilns can be passed through 
to  customers  in  circumstances  where  sites  are  cohabited 
with  customers.  In  addition  SigmaRoc  actively  monitors 
the evolution of the ETS Carbon Credit pricing and operates 
a  rolling  hedging  strategy,  typically  spanning  three  years 
forward.  It  also  expects  to  see  similar  strategies  applied 
in  take-over  targets  thereby  ensuring  alignment  in  the 
approach  to  both  pass-through  mechanisms  and  Carbon 
cost mitigation.

3. Carbon pricing within value chain

European  carbon  pricing  policies  may  lead  to  higher 
impacting  distribution 
operational  costs  for  shipping,

networks.  Moreover,  there  is  a  concern  that  customers 
might  be  incentivised  to  procure  materials  from  quarries 
located in less regulated jurisdictions, where carbon pricing 
is less stringent, potentially putting European suppliers at a 
competitive disadvantage. 

Mitigation

leverages  the  cohabitation  of  sites  with 
SigmaRoc 
to  ensure  more  sustainable  distribution 
customers 
practices.  By  strategically 
locating  sites  near  key 
customers,  the  Group  reduces  the  need  for  extensive 
shipping,  mitigating  the  impact  of  carbon  pricing  on 
transportation.

The Group can also avail itself to alternative transportation 
methods,  particularly  road,  rail  and  sea  transportation, 
depending on the overall cost.

4. Operational decarbonisation 

SigmaRoc’s  decarbonisation  ambitions  face  a  hurdle  in 
potential  localised  grid  capacity  constraints,  which  may 
impede the electrification of operations. This may increase 
operating  costs  if  reliance  on  pricier  fuels,  subject  to 
carbon levies, becomes necessary or cannot be phased out 
sufficiently quickly. 

Additionally,  the  transition  of  machinery  to  electricity  or 
biofuel carries the inherent risk of upfront costs. While these 
costs  are  strategically  integrated  into  business-as-usual 
activities, they remain a critical aspect of natural machinery 
churn.  There  may  however  be  limits  on  the  availability  of 
funding  for  such  a  transition,  and  potential  constraints  on 
the  availability  of  such  technology.  More  significantly,  the 
development  of  carbon  capture,  utilisation  and  storage 
(CCUS) capabilities on the estate poses a distinct risk given 
that CCUS investments do not align with routine equipment 
churn and require a focused financial strategy. Development 
of CCUS capabilities will also depend on third parties.

5. Failure to meet/maintain expected ESG credentials

There  is  a  risk  that  failure  to  meet  non-financial  reporting

potential divestment. Further, failure to maintain customer 
expectations  on  sustainability  performance  could  lead  to

1. Improved operational efficiency

Reducing  energy  consumption  through  a  programme  of 
efficiency  and  carbon  reduction  initiatives  may  decrease 
operating  costs,  increase  operating  margins  and  mitigate 
against the cost of future carbon pricing.

Operational  efficiency 
improvements  have  already 
been  introduced  across  the  Group  and  continue  to  be 
implemented  both  through  dedicated  programmes  and 
business-as-usual activities. Examples include:

•  Metering  and  monitoring  of  fuel  and  electricity 

consumption;

Limiting machinery idling – through software analysis 
and optimisation of shift patterns;

Switching to more efficient fuels, such as the transition 
from  coal  and  oil  to  biofuel  and  recycled  fuel  in  the 
North East Region;

• 

• 

• 

• 

• 

Intensity innovations – such as trials of low temperature 
asphalt;

Efficiency upgrades of machinery;

•  Consolidation of operations to improve efficiencies.

Strategy to capitalise

SigmaRoc is targeting energy intensity reductions of 2.5% by 
2030 from a 2021 base year, for 100% of all manufactured 
products to utilise waste/recycled materials by 2025, and for 
100%  utilisation  of  all  production  materials  by  2027. These 
targets are in excess of operational efficiency improvements 
that will be made as part of business-as-usual activities, such 
as the upgrade of machinery at the end of its lifespan to more 
efficient  models.  Efficiency  improvements  will  increasingly 
be aided by technological advancements in the future.

2. Transition to green electricity

Electrification  –  such  as  the  replacement  of  diesel-
powered  water  pumps  and  forklifts  with  electric 
alternatives;

Transition  to  green  electricity,  both  through  purchase 
of  renewable  grid  electricity  and  through  generation  of 
renewable electricity onsite, presents another opportunity to

comprised of many small business units, SigmaRoc can be 
more dynamic and reactive than peers.

Metrics & Targets

SigmaRoc currently reports mandatory energy consumption, 
scope 1, scope 2 and Business Travel emissions for its UK-
based  operations  as  required  under  UK  SECR  regulation, 
alongside  voluntary  energy  consumption  and  scope  1 
emissions  across  its  European  operations  in  excess  of 
SECR  requirements.  As  part  of  the  SBTi  submission, 
SigmaRoc has also undertaken efforts to estimate its scope 
3  footprint,  establishing  a  team  responsible  for  collecting 
and  monitoring  emissions  data  going  forward.  Reporting 
of  scope  3  emissions 
is  expected  to  become  more 
comprehensive as greater confidence in data is achieved.

The  specific  metrics  used  to  monitor  each  of  the  climate-
related  risk  and  opportunities  are  noted  in  the  relevant 
tables  above. 
In  addition,  SigmaRoc  reports  against 
industry-specific  SASB  metrics  including  air  emissions, 
water  consumption  and  biodiversity  impacts  (see  pages 
109-110), as well as additional metrics to satisfy MSCI and 
other ESG rating agency requirements (see page 94).

In  2021,  SigmaRoc  launched  its  Road  Map  to  Net  Zero, 
committing  the  Group  to  achieving  Net  Zero  across  its 
operations (Scope 1 & 2) by 2040, through the following:

2030 – 100% third party energy sourced from renewable 
means

2032 – Alternative fuels used fixed equipment (e.g. lime 
and asphalt)

2038 – All kilns are carbon neutral

In 2023, SigmaRoc submitted its net zero (Scope 1 and 2) 
by 2040 target to the SBTi, which is currently under review 
by SBTi.

Delivery  of  the  Road  Map  to  Net  Zero  was  a  corporate 
objective  linked  to  executive  remuneration  in  2022,  and 
inclusion of climate-related metrics within the remuneration 
approach going forward will be established for 2024.

installations will have the additional benefit of reducing the 
Group’s dependence on the electricity grid, thereby providing 
some comfort from any future energy price fluctuations and 
reducing any exposure to carbon pricing mechanisms.

Strategy to capitalise

SigmaRoc  has  published  targets  for  100%  of  third-party 
energy to be sourced from renewable sources by 2030. As 
part of the target, the Group is currently reviewing site and 
virtual  power  purchase  agreements  (PPAs)  across  each 
business, and businesses will continue to expand renewable 
generation.  The  Group  has  an  established  programme  of 
wind and solar installations to generate renewable electricity, 
including  existing  solar  photovoltaic  capacity  at  Soignies 
and  installations  at  Miedzianka  and  Wolica  (Poland)  and 
Dimension  Stone  (West)  during  2022.  Wind  turbines  have 
been installed at Soignies, and a successful feasibility study 
was undertaken for windmill construction at the Dimension 
Stone (West) site.

3. Increased market share in products aiding the transition 
to a green economy

SigmaRoc  is  well-placed  to  capitalise  on  the  net-zero 
transition.  Lime  is  a  key  resource  for  the  green  transition, 
with  various  applications  such  as  for  the  production 
and  recycling  of 
lithium  batteries,  decarbonisation  of 
construction  and  as  natural  carbon  sinks.  Additionally, 
SigmaRoc  has  developed  a  range  of  low-carbon  products, 
namely Greenbloc low-carbon concrete. By replacing 100% 
of  cement  with  alternative  materials,  Greenbloc  products 
have  substantially  reduced  curing  times  which  reduce 
energy  consumption  and  carbon  emissions.  Similarly, 
SigmaRoc  is  currently  developing  concrete  blocks  that 
sequester and permanently store waste CO2.

Development of such product ranges may increase access 
to  new  clients  and  markets,  as  the  demand  for  climate-
friendly construction materials grows. This opportunity may 
be  expected  to  manifest  in  the  medium-term,  although  it 
depends  on  the  extent  to  which  national  regulations  keep 
pace with the green transition.

Strategy to capitalise

Continue  to  focus  on  expanding  market-share  of  low-
carbon  products.  Align  offerings  with  evolving  climate-
friendly  construction  demands,  with  medium-term  impact 
contingent on regulatory advancements.

4. Resilience through innovation

Overall  there  is  a  significant  opportunity  for  the  Group  to 
continue to trial innovations in order to build and maintain 
climate  resilience.  The  specific  financial  impacts  will  vary 
depending  on  the  nature  and  outcomes  of  the  trial,  for 
example renewable energy programmes may help to reduce 
operational costs and thereby increase operating margins, 
whereas  product-related  trials  may  identify  new  product 
lines that may generate additional revenue.

Strategy to capitalise

Continue  to  target  cost  reduction  and  revenue  generation 
through  innovation  trials  and  renewable  energy  initiatives. 
The  Group  anticipates  that  the  return  on  investment  in 
alignment of new and existing operations to new and more 
efficient  machinery  will  be  short.  Additionally,  as  a  Group

to  give  it  more  focus.  The  Executive  Board  members  also 
ensure  these  topics  have  a  dedicated  agenda  item  at  the 
monthly  management  meetings.  The  Executive  members 
are charged with overall delivery whilst the Non-Executives 
challenge and give oversight and governance.

AUDIT COMMITTEE 

The Audit Committee ensures independent oversight of the 
Board which considers risks and opportunities when setting 
and reviewing strategy, major plans of action, policies, annual 
budgets  and  business  plans.  It  further  considers  matters 
when  setting  performance  objectives,  monitoring  Group 
performance  and  reviewing  and  approving  major  projects, 
capital expenditures and acquisitions. 

ESG COMMITTEE

The new ESG Committee will ensure oversight of ESG risks 
and  opportunities  when  setting  and  reviewing  strategy, 
major  plans  of  action,  policies,  annual  budgets  and 
business plans. It further considers matters when setting 
performance  objectives,  monitoring  Group  performance, 
and  reviewing  and  approving  major  projects,  capital 
expenditures and acquisitions.

RISK REPRESENTATIVE

To  ensure  the  Board  can  monitor  and  oversee  progress 
against goals and targets, the CTO leads risk at a Group level. 
The CTO works with each platform with regards to ongoing 
identification  of  risks,  opportunities,  and  potential  impacts 
on the business as well as reviewing performance metrics 
and  targets  and  ensuring  overall  continual  improvement. 
The  CTO  then  liaises  with  the  Board  and  the  relevant 
committees  so  that  the  Board  is  continually  updated  with 
regards to climate-related risks and opportunities as well as 
overall ESG matters.

SENIOR MANAGEMENT TEAM 

The  Group  is  set  up  as  discrete  operational  platforms 
with  each  platform  having  its  own  management  team.  As 
such  each  platform  Managing  Director  is  responsible  for 
assessing  and  managing  risks  and  opportunities  for  their 
respective platform. Managing Directors and the Company’s 
executive management team meet monthly to ensure that 
Group objectives are met as well as ensuring local risks and 
opportunities are recognised and managed.

Risk

"At a high level the Group’s risk 
appetite is reviewed annually 
by the Board which defines and 
approves the level of risk the 
Group is willing to accept in 
pursuit of its strategy, thereby 
guiding management." 

Charles Trigg 
Chief Technical Officer

The  Company’s  on-going  identification  and  assessment  of 
risks  including  ESG  and  climate-related  risks  allows  both 
the Board and management to consult and adapt to ensure 
efficient  and  effective  mitigation  with  the  Board  having 
overall responsibility.

The  Board  of  Directors,  executive  committee  and  senior 
management  teams  continually  identify  and  assess  risks 
and opportunities. This ensures each platform can focus on 
what is important to their jurisdictions as well as ensuring 
the Group is focusing on overall risks.

Risks  are  reported  and  discussed  at  the  executive 
committee  with  the  CTO  having  overall  responsibility  at 
an  executive  level.  Where  high  areas  of  risk  are  identified, 
specific  committees  are  set  up  to  monitor  and  control  the 
risk.  The  CTO  also  coordinates  with  key  subject  matter 
experts on Investor Relations, Legal, Safety, Carbon & Energy, 
Environment and Systems.

Risks are then discussed at the Board level who have overall 
responsibility with the Audit Committee taking the lead with 
a close working relationship with the CTO.

Risks  identified  are  assessed  based  on  aspects  such  as 
consequence,  impact,  likelihood,  inter  dependencies  and 
associated  timeframes  (short-,  medium-,  and  long-term 
time  horizons)  as  well  as  their  drivers  such  as  Political, 
Operational, Economic and Technical.

When assessing the potential size and scope of risks and 
opportunities, input from industry governing bodies (which 
are  in  regular  contact  with  government  and  associated 
agencies)  as  well  as  inputs  from  our  large  shareholders 
and  other  stakeholders  are  used  in  addition  to  our  usual 
assessment  and  prioritisation  techniques.  These  include 
analysis of probability and impact, risk frequency and risk 
urgency.  Where  necessary  these  are  then  modelled  with 
scenario  and  sensitivity  parameters  to  help  assess  both 
size and scope.

BOARD 

The  Board  has  overall  responsibility  for  risk  management 
and  internal  control  and  for  reviewing  effectiveness,  with 
specific  oversight  of  Code  of  Conduct,  ESG  risks  and 
climate-related  matters.  These  have  a  dedicated  agenda 
item at Board meetings with the Board meeting at least four 
times  per  year  with  a  new  ESG  committee  being  formed

Risk

Description

Mitigation

Foreign  exchange  risk:  The  Group  undertakes  limited  foreign 
exchange  transactions  as  it  sells  domestically  or  in  domestic 
currency with largely local input costs. Some M&A, OpEx and CapEx 
requires  foreign  exchange  purchases  and  management  considers 
foreign  exchange  hedging  strategies  where  significant  exposures 
may arise. 

Credit  risk:  Customer  credit  risk  is  managed  by  each  subsidiary. 
The Group principally manages credit risk through management of 
customer  credit  limits.  The  credit  limits  are  set  for  each  customer 
based on the creditworthiness of the customer and the anticipated 
levels of business activity. These limits are initially determined when 
the  customer  account  is  first  set  up  and  are  regularly  monitored 
thereafter. 

Liquidity risk: Ensure sufficient funding and facilities in place to meet 
any  foreseeable  peak  in  borrowing  requirements  and  liabilities  by 
maintaining  strong  relationships  with  our  banks  and  shareholders. 
Internally,  we  continuously  monitor  forecasts  and  cash  flows  to 
ensure that we maintain significant headroom and have self-imposed 
2  times  leverage,  which  is  only  exceeded  temporarily  and  worked 
down as quickly as possible. 

Interest  rate  risk:  The  Group  finances  its  operations  through  a 
mixture  of  retained  profits  and  bank  borrowings,  based  on  floating 
rates.  Interest  rate  fixing  has  been  reviewed  but  none  have  been 
entered into during the year or at the year end. 

We  safeguard  the  health  and  safety  of  employees,  contractors  and 
others  working  on  behalf  of  the  Group  with  experienced  health  and 
safety  professionals  who  provide  relevant  training  and  help  develop 
a  strong  culture  alongside  the  management  teams;  all  of  which  is 
overseen and audited by our Group HSEQ director with the support of 
consultants where necessary.  

We are constantly improving communication and reporting across the 
Group through simple and effective systems and processes such as 
our HS Engagement and Monitoring software, Visible Felt Leadership, 
HS Committees, back to work and pitstops.

IT  support  teams  and  service  providers  continue  to  monitor  and 
respond  to  new  and  expanding  cyber  risks  by  implementing  best 
practice  in  IT  security  management,  back-up  systems  and  risk 
management software courtesy of our cyber insurance providers. 

Outdated  software  and  hardware  are  updated,  and  cloud  solutions 
embraced,  to  minimise  negative 
impacts  and  allow  continual 
operations. 

Group  general  counsel  and  engagement  of  external  specialists  to 
monitor legislative changes and conduct ongoing training.  

Hold  appropriate  business  accreditations  and 
insurances  and 
ensure there are compliance procedures, policies, ISO standards and 
independent audit processes which seek to ensure that regulatory and 
compliance procedures are fully complied with. 

Finance, 
Liquidity and 
Currency 

Foreign exchange risk: As the Group 
transacts  in  currencies  other  than 
Sterling,  exchange  rate  fluctuations 
may  adversely  impact  the  Group’s 
results. 

Credit  risk:  Through  its  customers, 
the Group is exposed to a counterparty 
risk  that  accounts  receivable  will  not 
be settled leading to a financial loss to 
the Group. 

Liquidity risk: Insufficient funds could 
result  in  the  Group  being  unable  to 
fund  its  operations  or  to  continue 
to  invest  organically  or  to  undertake 
acquisitions. 

Interest  rate  risk:  Movements 
in 
interest  rates  could  adversely  impact 
in  higher 
the  Group  and 
financing payments to service debt.

prevent 
from  meeting 
customer demand. 

the  Group 

The  Group  has  the  ability  to  transfer  some  of  its  production  across 
its network of plants and is able to engage subcontractors to reduce 
the  impact  of  certain  production  disruptions.  In  relation  to  supplier 
disruption or failure, further third-party suppliers have been identified 
who can maintain service in the event of a disruption.  

The  Group’s  wide  geographical  spread  mitigates  this  risk  to  some 
extent and allows it to manage its production facilities to mitigate the 
impact of such disruption. 

The Group operates comprehensive quality control procedures across 
its sites with both internal and external audit reviews of product quality 
completed  to  ensure  conformance  with  internationally  recognised 
standards. All accredited staff undergo rigorous training programmes 
on quality and the technical teams carry out regular testing of all of our 
products to provide full technical data on our product range.

Capital  expenditure  relates  to  purchases  of  land  and 
minerals, new plant and machinery and improvements to 
existing infrastructure across the Group.

PPA

BDO  UK  LLP  undertook  the  PPA  exercise  required  under 
IFRS 3 to allocate a fair value to the acquired assets of JQG 
and Goijens.

The PPA process resulted in a reduction of goodwill recorded 
on  the  Statement  of  Financial  Position  of  the  Group  for 
JQG from £49.8 million to £16.7 million and a reduction in 
Goijens from £5.1 million to £1.6 million. The reduction was 
to transfer the value of goodwill to tangible assets for land 
and buildings, land and mineral reserves, intangible assets 
and deferred tax assets.

The  Company’s  loss  after  taxation  for  2023  amounts 
to  £42.9  million,  of  which  £30.0  million  relates  to  non-
underlying  items,  while  the  Group’s  non-underlying  items 
totalled  £42.1  million  for  the  year,  of  which  £12.3  million,

INTEREST AND TAX

Net  finance  costs  in  the  year  totalled  £15.9  million  (2022: 
£10.4 million) including associated interest on bank finance 
facilities,  as  well  as  interest  on  finance  leases  (including 
IFRS 16 adjustments) and hire purchase agreements.

A  tax  charge  of  £12.4  million  (2022:  £9.1  million)  was 
recognised in the year, resulting in a tax charge on profitability 
generated  from  mineral  extraction  in  the  Channel  Islands 
and profits generated through the Group’s UK, Belgium and 
Nordic based operations.

EARNINGS PER SHARE

Basic EPS for the year was 1.98 pence (2022: 4.89 pence) 
and underlying basic EPS (adjusted for the non-underlying 
items  mentioned  above)  for  the  year  totalled  8.12  pence 
(2022: 8.03 pence).

STATEMENT OF FINANCIAL POSITION

Net assets at 31 December 2023 were £514.9 million (2022: 
£469.9  million).  Net  assets  are  underpinned  by  mineral 
resources,  land  and  buildings  and  plant  and  machinery 
assets of the Group.

CASH FLOW

Cash generated by operations was £65.4 million (2022: £87.7 
million). The Group spent £30.2 million on acquisitions net 
of cash acquired, £37.1 million on capital projects including 
acquisition  of  intangibles,  raised  £29.2  million  net  of  fees 
from the issue of equity, generated £5.2 million through the 
disposal of non-core property, plant & equipment, and repaid 
net borrowings of £27.0 million. The net result was a cash 
outflow for the year of £11.5 million.

NET DEBT

Net  debt  at  31  December  2023  was  £182.4  million  (2022: 
£193.8 million).

BANK FACILITIES

On  22  November  2023  the  Company  entered  a  new 
syndicated  senior  credit  facility  of  up  to  €750  million  (the 
‘New Debt Facilities’) led by Santander UK and BNPP, with the 
syndicate including several major UK and European banks 
and  a  further  €125  million  bridge  loan  (‘Bridge  Loan’). The 
New Debt Facilities were partially drawn on 4 January 2024 
in  connection  with  the  CRH  Lime  Acquisitions,  specifically 
CRH Deal 1, and the legacy debt facility was repaid as part 
of this process.

The New Debt Facilities comprise a €600 million committed 
term  facility,  €150  million  revolving  credit  facility  and  a 
further €100 million uncommitted accordion.

The  Group’s  New  Debt  Facilities  have  a  maturity  date  of  
21  November  2028  and  are  subject  to  a  variable  interest  
rate  based  on  EURIBOR  plus  a  margin  depending  on 
underlying EBITDA.

STRATEGIC REPORTSIGMAROC ANNUAL REPORT 2023141

The  Group’s  New  Debt  Facilities  are  subject  to  covenants 
which  are  tested  monthly  and  certified  quarterly.  These 
covenants are:

•  Group interest cover ratio set at a minimum of 3.5 times 
EBITDA while the Bridge Loan remains outstanding and 
then 4.0 times thereafter; and

• 

 A  maximum  adjusted  leverage  ratio,  which  is  the  
ratio  of  total  net  debt,  including  further  borrowings  
such as deferred consideration, to adjusted EBITDA, of 
3.95x in 2024.

The Bridge Loan has a maturity date of 21 November 2024, 
with options for two 6-month extensions which if exercised 
would push maturity to 21 November 2025. The Bridge Loan 
is subject to a variable interest rate based on EURIBOR plus 
a margin as follows:

• 
• 
• 

• 

2% for months 0 – 6

3% for months 7 – 12

4% for months 13 – 18 (assuming exercise of the first 
extension option)

5%  for  months  19  –  24  (assuming  exercise  of  the 
second extension option)

As at 31 December 2023, the Group comfortably complied 
with  its  bank  facility  covenants  under  the  terms  of  the 
legacy  debt  facility  and  total  undrawn  facilities  available 
to  the  Group  under  the  legacy  debt  facility  amounted  to 
approximately £173 million.

CAPITAL ALLOCATION

We  prioritise  the  maintenance  of  a  strong  balance  sheet 
and  deploy  our  capital  responsibly,  allowing  us  to  commit 
significant  organic  investment  to  our  business  whilst 
continuing to pursue acquisitions to accelerate our strategic 
development.  This  conservative  approach  to  financial 
management  will  enable  us  to  continue  pursuing  capital 
growth for our shareholders. 

DIVIDENDS

Subject  to  availability  of  distributable  reserves,  dividends 
will  be  paid  to  shareholders  when  the  Directors  believe 
it  is  appropriate  and  prudent  to  do  so.  The  Group  has 
achieved  significant  capital  growth  since  its  inception  and 
the  Directors  expect  to  commence  dividend  payments 
once  the  Group’s  Covenant  Leverage  is  below  1.5  times, 
which following CRH Deal 1 of the CRH Lime Acquisitions, 
is  currently  above  2  times.  The  Directors  therefore  do  not 
recommend  the  payment  of  a  dividend  for  the  year  (31 
December 2022: nil).

POST BALANCE SHEET EVENTS

Post  2023  close  we  have  conducted  a  series  of  activities 
worthy of mention in this Annual Report. Further information 
is set out in Note 38.

This report was approved by the Board on 17 March 2024

CHIEF INFORMATION 
OFFICER

"I am delighted to share that the 
Group has concluded a robust 
year with no noteworthy  IT 
incidents. We have successfully 
started the successful 
deployment of new ERP systems 
throughout the Nordics, 
and maintained an ongoing 
commitment to enhancing and 
innovating our operations." 

Fons Vermorken 
Chief Information Officer

Despite  the  economic  challenges,  we  have  effectively 
navigated through a substantial pipeline of projects, closing 
a large transaction and ensuring the Group remains ahead 
in terms of systems and digital advancement. Our primary 
objectives continue to revolve around innovation within the 
Group and its internal processes, alongside maintaining the 
highest standards in cyber and risk management.

CYBER RISK MANAGEMENT

The  security  of  SigmaRoc  IT  systems  is  critical,  as  any 
potential  breaches  can  severely  disrupt  our  operations. 
Inadequate  management  of  cyber  risk  may 
lead  to 
adverse  consequences  such  as  impacting  our  financial 
performance,  endangering  employee  safety,  exposing 
confidential information, harming our brands and reputation 
and exposing us to legal liabilities.

IMPACT ON THE GROUP

The surge in cyber threat targeting businesses has notably 
increased  recently,  partly  to  the  emergence  of  new  digital 
tools  like  ransomware,  heightened  involvement  of  nation-
states, increased interconnectivity and a substantial rise in 
the profitability of cyber offenses.

SigmaRoc 
operational  processes, 
industrial  production, 
including 
efficient  operations,  environmental  management,  health 
and  safety,  communications,  transaction  processing  and 
risk  management.  Moreover,  our  extended  supply  chains 

CIO Systems & Digital Innovation Report 

are also vulnerable to cyber threats, although largely beyond 
our direct control.

To mitigate potential risks, we closely monitor the security of 
these intricate supply chains. The growing use of machine 
learning  and  artificial  intelligence  further  amplifies  the 
sophistication  and  frequency  of  fraudulent  activities.  The 
emergence  of  ‘Deepfake’  technology,  leveraging  machine 
learning  to  manipulate  audio  and  visual  content,  adds  to 
the  risk  of  phishing  or  fraud  attacks  impersonating  senior 
executives.

Despite  significant  investments  in  enhancing  our  systems, 
processes  and  networks,  SigmaRoc  acknowledges  that 
achieving  complete  security  is  challenging.  However,  we 
remain  dedicated  to  collaborating  with  high  quality  third-
party IT providers to enhance IT safety and inform staff of 
tactical innovations utilised in cybercrime.

OUR CURRENT DEVELOPMENTS

Geopolitical turmoil has significantly expanded the potential 
attack  surface  area  due  to  remote  working,  thereby 
increasing  the  risk  of  cyber  assaults  for  all  businesses. 
Furthermore,  the  widespread  use  of  phone  and  tablet  like 
devices has increased significantly in recent years as being 
part  of  the  digital  transformation  of  the  Group.  SigmaRoc 
has  noted  a  rise  in  both  the  frequency  and  complex  of 
cyberattacks targeting its operations.

Our  cybersecurity  monitoring  systems  consistently  detect 
attempts to breach our networks and systems. The increase 
was  most  noticeable  post  the  announcement  of  the  war 

in  Ukraine.  During  2022,  there  was  an  instance  where  one 
of  our  email  servers  experienced  a  substantial  series  of 
attacks.  However,  the  protection  systems  in  place  were 
stringent  enough  for  these  attacks  not  to  have  resulted  in 
any significant breach of our IT infrastructure or caused any 
notable business disruptions.

cyberattacks,  which  entail  the  manipulation  of  legitimate 
third-party software to spread malware or gain unauthorised 
access  to  systems  by  impersonating  senior  management, 
will  rise.  Additionally,  the  Group  predicts  that  ransomware 
will  continue  to  pose  a  significant  threat  to  firms  in  the 
industry  that  have  become  ever  more  informatised  over 
recent years.

HOW WE MITIGATE RISK

SigmaRoc takes proactive measures to enhance IT security 
awareness  and  education  among  its  personnel.  Monthly 
cyber security trainings are conducted to keep staff informed 
about the latest cyber-threats and ransomware practices.  

In  line  with  its  decentralized  platform  structure,  SigmaRoc 
has  organized  the  Group's  IT  infrastructure  similarly  to 
mitigate  cyber  risks. This  includes  implementing  a  layered 
cybersecurity  setup,  proactive  monitoring, 
independent 
penetration  testing,  off  network  data  backups  and  data 
backup  restoration  tests  to  validate  system  security 
wherever possible.

To  safeguard  critical  systems,  the  Group 
implements 
privileged access management protocols and ensures that

system software is kept up to date and maintains regional 
platforms  to  enforce  patch  compliance.  Multiple  layers  of 
email security are employed, with segregated email servers 
running  on  different  domains.  Additionally,  computers  and 
servers are hardened against malware attacks.

Corporate applications and communications utilise multiple 
including  two-factor  authentication 
layers  of  security, 
and  virtual  private  network  (VPN)  technology  for  remote 
access as needed. While SigmaRoc does not adopt a global 
approach  to  IT  security,  it  applies  consistent  standards 
across  different  platforms  to  proactively  monitor  and 
manage  cyber  risks,  as  well  as  to  segregate  servers.  This 
segregation helps prevent spill-over effects from attacks and 
mitigates their impact on the Group. Regular engagement of 
third-party  penetration  testing  further  ensures  the  security 
of our IT systems.

DIGITAL TRANSFORMATION AND INNOVATION

industry  standards  through 

SigmaRoc 
is  committed  to  spearheading  the  digital 
transformation  within  the  quarried  materials 
industry, 
innovative 
aiming  to  set 
solutions. Leveraging powerful handheld computer devices, 
and  geolocation  capabilities  for  equipment  has  enabled 
the  Group  to  enhance  performance,  cost  efficiency  and 
environmentally friendly. SigmaRoc is known for being the 
first  mover  and  adopter  of  technologies  that  can  change 
the industry and make significant steps towards a net-zero 
future.

CASE STUDY: MACHINEMAX

MachineMax,  a  technology  adopted  by  SigmaRoc  several 
years  ago,  has  become  firmly  integrated  into  the  Group's 
operations.  As  one  of  the  earliest  adopters,  SigmaRoc 
contributed  to  enhancing  the  product  and  reaped  the 
benefits of its technological advancements.

Given the significance of heavy equipment in our operations, 
MachineMax plays a vital role in optimizing its management. 
By  tracking  key  operational  metrics,  it  has  boosted  fleet 
productivity, positively impacting machine utilisation, idling 
time,  fuel  consumption,  emissions,  location,  tracking,  and 
operating hours. This comprehensive telematics sensor has 
resulted in improved top-line revenue and reduced operating 
costs, while simultaneously decreasing emissions and the 
carbon footprint of the Group.

CASE STUDY: HIGHVIZZ

Ensuring the safety and security of our colleagues within a 
safe  work  environment  is  the  primary  focus  for  every  site 
manager and the entire Group. To achieve this goal, we have 
developed  a  customized  health  and  safety  solution  based 
on  the  insights  of  our  operation  managers,  who  possess 
firsthand knowledge of what best serves their teams.

Our  real-time  health  and  safety  system,  HighVizz,  goes 
beyond  mere  reporting;  it  prioritizes  incident  prevention 
and  fosters  a  robust  safety  culture.  Accessible  on  every 
employee's phone, HighVizz enables instant reporting and, 
crucially,  encourages  safety  discussions  originating  from 
within  the  operation  rather  than  being  dictated  by  senior 
management.

Empowering employees to take responsibility for their own 
safety  and  that  of  their  colleagues  is  the  most  effective 
approach  to  enhancing  health  and  safety  standards 
throughout the Group.

the  continued  success  of  our  business.  We  maintain 
purposeful  and  close  relationships  with  them,  and  our 
sustainable  long-term  growth  strategy  provides  value  for

We are making a material difference through the impact we

benefit of its members and other stakeholders through the 
decisions it has taken in the year to 31 December 2023.

The Board is responsible for establishing the Group’s long-
term strategy and objectives; however, it recognises that the 
executive  and  senior  managers  of  our  businesses  play  an 
important role in achieving these goals. The Board has an 
effective  delegation  structure  in  place  which  allows  local 
management  and  their  workforces  to  engage  effectively 
and  react  accordingly,  to  understand  the  needs  of  their 
suppliers, customers, communities and regulators at a local 
level. The Board is of the opinion that engaging the majority 
of  its  stakeholders  on  a  local  level  is  the  most  effective 
process for the long-term success of the Group.

STRATEGIC REPORTSIGMAROC ANNUAL REPORT 2023HIGHLIGHTS OF STAKEHOLDER ENGAGEMENT IN 2023

The  Board,  together  with  members  of  the  Executive 
Committee and other senior and local managers, continued 
to engage proactively with all our stakeholders. The following 
are just some examples of those engagements in 2023.

COLLEAGUES

Focus  on  development  training  and  succession  planning 
across the Group, with continued emphasis on behavioural 
safety  techniques,  health  &  safety  reviews  and  training. 
More  specifically,  in  the  UK  introduced  “Peptalk”,  an 
app-based  platform  designed  to  promote  employee 
engagement and wellbeing.

CUSTOMERS AND SUPPLIERS

Our  partnership  with  one  of  our  key  suppliers,  Heidelberg 
Materials,  stands  as  a  testament  to  our  commitment  to 
collaborative success. Together, we are tackling the crucial 
challenge  of  decarbonising  the  built  environment,  aligning 
our efforts for a sustainable future. The trust we've cultivated 
is evident, highlighted by our North West Region MD Michael 
Roddy participating as a speaker at their prestigious annual 
commercial  conference,  demonstrating  the  depth  of  our 
relationship and shared values.

At CDH, working closely with Cereser Marmi, an Italian marble 
and natural stone company, has illustrated the importance 
of  customer  experience  within  the  natural  stone  sector  in 
today's market landscape. Recognising the significance of 
presenting our products with a touch of luxury both to our 
customers and at the quarry itself has been instrumental in 
our strategy. By imbuing our offerings with a sense of luxury, 
we not only enhance the value proposition for our existing 
clientele but also open up avenues for prestigious projects 
on  a  global  scale.  One  notable  outcome  of  this  approach 
is Puccini Blue. This exquisite creation emerged from what 
was  once  considered  a  waste  product  –  stone  with  white 
veins  that  had  long  been  overlooked  or  discarded  in  local 
markets.  Transforming  this  into  a  "luxury  design"  product 
has  been  a  revelation.  Puccini  Blue  exudes  the  same 
elegance  and  sophistication  as  high-end  marble,  injecting 
fresh dynamism into the market.

Similarly,  the  Penn  Station  project  presented  a  formidable 
challenge, demanding a delicate balance between meeting 
volumetric requirements and stringent quality standards set 
by the client. Through astute navigation of the client's needs 
and  leveraging  our  in-depth  knowledge  of  the  product,  we 
succeeded  in  surpassing  expectations.  Drawing  from  the 
diverse qualities offered by the quarry, we tailored solutions 
to fulfil the project's demands. In this endeavour, the mantra 
was clear – where there seemed to be obstacles, we sought 
solutions. Collaboration with key partners proved to be key 
in  overcoming  the  hurdles  we  faced.  By  working  hand  in 
hand with the architect and Vornado, we fostered a culture 
where "NO" was a call to innovate. This collaborative spirit 
engendered  trust  and  confidence,  propelling  the  Penn 
Station project toward its completion. Its success not only 
stands  as  a  testament  to  our  capabilities  but  also  serves 
as  a  compelling  marketing  asset,  poised  to  bolster  CDH's 
presence in the global export market.

REGULATORS,  LOCAL  GOVERNMENT  AND  INDUSTRY 
ASSOCIATIONS

Each  platform  works  closely  with  their  local  regulators, 
governments  and  industry  associations  with  many  of  our 
senior  management  team  representing  either  working 

groups, committees or holding board positions such as our 
board position with the European Lime Association.

By  having  our  platforms  work  closely  with  these  bodies,  
we  ensure  we  are  at 
local  
communities, 
forward  as 
ambassadors of best practice.

INVESTORS AND LENDERS

As part of our commitment to investors and lenders, Tom 
Jenkins was employed as the Head of Investor Relations for 
the Group.

COMMUNITIES

We continue to develop our working relationships with the 
military and military employment charities and are registered 
with  the  Career  Transition  Partnership.  We  help  facilitate 
resettlement  and  transition  from  military  to  civilian  life  as 
well as support civilian spouses and partners of serving and 
ex-Forces personnel on their journey into employment.

Across  all  our  platforms,  our  business  model  of  local 
business for local communities ensures that we continue to 
integrate into the areas we work, supporting both other local 
businesses, projects and communities.

corporate  governance  standards  in  place  and  that  these 
requirements are followed and applied within the Company 
as a whole.

The corporate governance arrangements that the Board has 
adopted are designed to ensure that the Company delivers 
long  term  value  to  its  Shareholders  and  that  Shareholders 
have the opportunity to express their views and expectations 
for the Company in a manner that encourages open dialogue 
with the Board.

The Board recognises that its decisions regarding strategy 
and risk will impact the corporate culture of the Company 
as  a  whole  and  that  this  will  impact  the  performance  of 
the  Company.  The  Board  is  very  aware  that  the  tone  and 
culture set by the Board will greatly impact all aspects of the 
Company as a whole and the way that employees behave. 
A  large  part  of  the  Company’s  activities  are  centred  upon 
what  needs  to  be  an  open  and  respectful  dialogue  with 
employees,  customers  and  other  stakeholders.  Therefore, 
the  importance  of  sound  ethical  values  and  behaviours  is 
crucial to the ability of the Company successfully to achieve 
its corporate objectives. The Board places great importance 
on this aspect of corporate life and seeks to ensure that this 
flows through all that the Company does.  

The  key  governance  related  matters  that  occurred  during 
the financial year ended 31 December 2023 were:

1.  

 Identifying potential new NEDs for the Board.

2.  

 Adoption of Competition Compliance and Diversity 
& Inclusion policies.

CORPORATE GOVERNANCE REPORT 

The QCA Code sets out 10 principles that should be applied. 
These are listed below together with a short explanation of 
how the Company applies each of the principles: 

PRINCIPLE ONE 

Establish  a  strategy  and  business  model  which  promote 
long-term value for shareholders

Strategy and purpose: The Company is a lime and limestone 
group targeting investments in quarried materials assets in 
the UK and Northern Europe. 

Lime  and  limestone  are  key  resources  in  the  transition  to 
a  more  sustainable  economy.  New  applications  for  lime 
and limestone products as part of a drive for sustainability 
include  the  production  and  recycling  of  lithium  batteries, 

the  decarbonisation  of  construction 
including  through 
substitution  of  cementitious  material  and  new  building 
materials,  and  environmental  applications  including  lake 
liming, air pollution and direct air capture.

The Group’s aim is to create value for shareholders through 
the  successful  execution  of  its  buy  and  build  strategy,  by 
purchasing  assets  in  fragmented  materials  markets  and 
extracting  efficiencies  through  active  management  and 
forming the assets into larger groups. It seeks to de- risk its 
investments  through  the  selection  of  projects  with  strong 
asset backing. 

Business  model:  The  acquired  assets  provide  a  strong 
operating  platform,  diversified  income  streams  and  stable 
cash  flows  in  order  to  grow  the  Group  and  execute  on  its 
strategy further.

The Group is run as a commercially minded business, seeking 
to return an increase on investment capital to Shareholders. 
Proven  methods  of  raising  capital  through  recognised 
means  available  to  publicly  listed  companies  are  relied  on 
to  fund  growth  acquisitions.  Following  each  acquisition, 
the Group seeks to implement operational efficiencies that 
improve  safety,  enhance  productivity,  increase  profitability 
and ultimately create value for Shareholders.

PRINCIPLE TWO 

Seek  to  understand  and  meet  shareholder  needs  and 
expectations

Shareholder dialogue: The Company remains committed to 
listening  and  communicating  openly  with  its  shareholders 
to ensure that its strategy, business model and performance 
are  clearly  understood.  Understanding  what  analysts  and 
investors  think  about  the  Company,  and  in  turn,  helping 
these audiences understand the Company’s business, is a 
key part of driving the business forward and the Company 
actively seeks dialogue with the market. The Company does 
so via investor roadshows, attending investor conferences, 
hosting capital markets days and through regular reporting.

Private  Shareholders:  The  AGM  is  the  main  forum  for 
dialogue  between  retail  Shareholders  and  the  Company. 
The Directors routinely attend the AGM and are available to 
answer questions raised by Shareholders. The results of the 
AGM are subsequently published on the Company’s corporate 
website.  In  addition,  the  Company  has  engaged  with 
Investor  Meet  Company,  a  technology  platform  that  allows 
presentations and Q&A between Company management and 
private  investors.  Regular  updates  have  been  made  on  this 
platform throughout the year. Other ad hoc presentations to 
private investors have been made in the year.

Institutional  Shareholders: The  Company  actively  seeks  to 
build  relationships  with  institutional  Shareholders  through 
calls,  presentations  and  visits.  Shareholder  relations  are 
managed  primarily  by  the  CEO  and  the  Head  of  Investor 
Relations, but the Executive Chairman and Senior Independent 
Non-Executive Director are also available to meet with major 
shareholders to discuss issues of importance.

PRINCIPLE THREE 

into  account  wider  stakeholder  and  social 
Take 
responsibilities and their implications for long-term success

GOVERNANCE REPORTSIGMAROC ANNUAL REPORT 2023Engagement:  Engaging  with  stakeholders  strengthens 
relationships  and  helps  make  better  business  decisions 
to  deliver  on  commitments.  The  Company  is  regularly 
updated  on  wider  stakeholder  engagement  feedback 
to  stay  abreast  of  stakeholder  insights  into  the  issues 
that  matter  most  to  them  and  the  Group’s  business,  and 
to  enable  the  Board  to  understand  and  consider  these 
issues  in  decision-making.  With  Shareholders,  suppliers 
and customers, employees are one of the most important 
stakeholder  groups  and  employees’  engagement  surveys 
and feedback are closely monitored.

Employees,  contractors  and  suppliers:  The  Group  has 
established  a  safe  and  healthy  work  environment,  which 
complies  with  the  relevant  occupational  health  &  safety 
laws.  The  Group  ensures  that  the  workforce  is  provided 
with sufficient training to develop the appropriate skills and 
knowledge to complete the tasks requested of them.

For the sake of occupational health & safety, all contractors 
and sub-contractors are treated in exactly the same manner 
as employees.

Communities: The Group has supported and given back to 
the community by participating in a selection of projects in 
recent  years.  Further  details  of  the  Group’s  environmental, 
social  and  governance  related  initiatives  for  the  year  are 
detailed  in  the  ESG  and  Stakeholder  Reports  included  in 
these Accounts. 

Modern  slavery:  As  part  of  our  mission  to  “do  the  right 
thing” we oppose modern slavery in all its forms and work 
to prevent it by any means that we can. We expect anyone 
who has any suspicions of modern slavery in our business 
or our supply chain to raise their concerns without delay.

PRINCIPLE FOUR 

Risk Management 

Embed  effective  risk  management,  considering  both 
opportunities and threats, throughout the organisation

Risk register: To assist the Board with effectively managing 
risk across the Group the Company has established a risk 
register which is reviewed periodically.

Internal  control:  The  Company  has  an  established 
framework  of  internal  control,  the  effectiveness  of  which 
is  regularly  reviewed  by  executive  management,  the  Audit 
Committee and the Board in light of an ongoing assessment 
of significant risks facing the Company and the Group.

The Company recognises that maintaining sound controls 
and discipline is critical to managing the downside risks to 
its business plan.

The Board has ultimate responsibility for the Group’s system 
of  internal  control  and  for  reviewing  its  effectiveness. The 
Audit Committee assists the Board in discharging its duties 
regarding  the  financial  statements,  accounting  policies 
and  the  maintenance  of  proper  internal  business,  and 
operational and financial controls.

The Board presently considers that the internal controls in 
place are appropriate for the size, complexity and risk profile 
of the Group. 

PRINCIPLE FIVE 

Maintain  the  board  as  a  well-functioning,  balanced  team 
led by the chair

157

Board  composition:  The  Board  comprises  the  Executive 
Chairman, two Executive Directors, and four Non-Executive 
Directors, all of whom are deemed independent. The Board 
considers,  after  careful  review,  that  the  Independent  Non-
Executive Directors bring an independent judgement to bear.

The biographies of the members of the Board can be found 
on the Company’s website (https://sigmaroc.com/investor-
relations/board/).

The  Board  is  satisfied  that  it  has  a  suitable  balance 
between  independence  and  knowledge  of  the  Group  and 
its  operations  to  discharge  its  duties  and  responsibilities 
effectively.  The  Board  receives  periodic  updates  from  the 
management  team.  All  Directors  are  encouraged  to  use 
their  independent  judgement  and  to  challenge  all  matters, 
whether strategic, operational or financial.

Membership  of  the  Board,  its  activities,  performance  and 
composition are subject to periodic review.

Conflicts of interest: The Company has effective procedures 
in place to monitor and deal with conflicts of interest. The 
Board  is  aware  of  the  other  commitments  and  interests 
of  its  Directors,  and  changes  to  these  commitments  and 
interests  are  reported  to,  and,  where  appropriate,  agreed 
with, the rest of the Board.

Suitability:  The  Board  guides  and  monitors  the  business 
and affairs of the Company on behalf of the shareholders by 
whom they are elected and to whom they are accountable. 
The  Board  is  satisfied  that  given  its  size  and  stage  of 
development,  between  the  Directors,  it  has  an  effective 
and  appropriate  balance  of  skills  and  experience  across 
technical, commercial and financial disciplines.

transparent procedure for appointments.

Corporate Governance Report

Independent  advice:  All  Directors  are  able  to  take 
independent professional advice in the furtherance of their 
duties, if necessary, at the Company’s expense. In addition, 
the Directors have direct access to the advice and services 
of the Company Secretary and Chief Financial Officer.

The  Board  and  its  Committees  receive  appropriate  and 
timely  information  prior  to  each  meeting,  with  a  formal 
agenda  being  produced  for  each  meeting,  and  Board  
and  Committee  papers  distributed  several  days  before 
meetings take place.

PRINCIPLE SEVEN 

Evaluate  board  performance  based  on  clear  and  relevant 
objectives, seeking continuous improvement

Appraisal:  The  Chairman  assesses 
individual 
contributions  of  each  member  of  the  Board  to  ensure

Succession planning is considered by the Board as a whole. 
The Board will annually review and make recommendations 
relating to talent management and succession planning for 
the Board and the CEO.

PRINCIPLE EIGHT 

Promote a corporate culture that is based on ethical values 
and behaviours

Code of conduct: The Board has adopted a code of conduct 
which provides a framework for ethical decision-making and 
actions  across  the  Group.  The  code  of  conduct  reiterates 
the  Group’s  commitment  to  integrity  and  fair  dealing  in 
its  business  affairs  and  its  duty  of  care  to  all  employees, 
contractors and stakeholders.

Each  Board  member’s  adherence  to  the  Group’s  code  
of conduct is assessed as part of the annual Board review 
and appraisal.

Anti-corruption and bribery: The Board has adopted an anti-
corruption and bribery policy further to ensure honest and 
ethical conduct of employees. The Company also provides 
periodic training to employees to ensure they are aware of 
their responsibilities in relation to bribery and corruption.

The Company has a zero-tolerance approach to bribery and 
corruption. The Company’s General Counsel is responsible 
for  monitoring  compliance  with  and  maintaining  the  anti-
corruption and bribery policy.

PRINCIPLE NINE 

Maintain  governance  structures  and  processes  that  are  fit 
for purpose and support good decision-making by the board

Board programme: The Board is responsible for approving 
the  Company  strategy  and  policies,  for  safeguarding  the 
assets of the Company, and is the ultimate decision-making 
body  of  the  Company  in  all  matters  except  those  that  are 
reserved for specific shareholder approval.

The Board meets at least four times each year in accordance 
with its scheduled meeting calendar and maintains regular 
dialogue between Board members, in particular between the 
CEO, the Chairman and the non-executive Board members.

Roles  and  responsibilities:  There  is  a  clear  division  of 
responsibility  at  the  head  of  the  Company  between  the 
Chairman and the CEO.

The Board is supported by the Audit, Remuneration, AIM and 
MAR Compliance, ESG and Nominations committees. Each 
committee has access to such resources, information, and 
advice as it deems necessary, at the cost of the Company, to 
enable the committee to discharge its duties.

As the Group grows and develops the Board will periodically 
review  its  corporate  governance  framework  to  ensure  it 
remains appropriate for the size, complexity and risk profile 
of the Group.

PRINCIPLE TEN 

Communicate  how  the  company  is  governed  and  is 
performing  by  maintaining  a  dialogue  with  shareholders 
and other relevant stakeholders

Communication: The Company attaches great importance 
to  providing  shareholders  with  clear  and  transparent 
information  on  the  Company's  activities,  strategy  and 
financial position through the Annual Report and Accounts, 
full-year and half-year announcements, the Annual General 
Meeting (AGM) and one-to-one meetings with large existing 
or potential new shareholders.

The  Company  announces  significant  developments  via 
various  outlets  including  the  London  Stock  Exchange’s 
Regulatory News Service (RNS).

The Company made its policies and the terms of reference 
for its committees available on its website.

The  Board  receives  regular  updates  on  the  views  of 
shareholders  through  briefings  and  reports  from  the  CEO 
and the Company’s brokers. The Company communicates 
with  institutional  investors  frequently  through  briefings 
with management. In addition, analysts’ notes and brokers’ 
briefings  are  reviewed  to  achieve  a  wide  understanding  of 
investors’ views.

CHAIR STATEMENT 

The Audit Committee was chaired by myself and comprises 
of Jacques Emsens as the other member. The Committee 
has relevant financial experience at a senior level as set out 
in their biographies. The Audit Committee met three times 
formally  in  2023  and  also  held  informal  discussions  with 
the external auditor as appropriate. The principal activities 
of  the  Audit  Committee  in  respect  of  the  year  ended  31 
December 2023, and the manner in which it discharged its 
responsibilities, were as follows: 

FINANCIAL STATEMENTS 

The  Audit  Committee  reviewed  and  agreed  the  external 
auditor’s strategy and approach in advance of their audit for 
the  year  ended  31  December  2023,  and  reviewed  reports 
on  the  outcome  of  the  audit.  The  Audit  Committee  also 
reviewed  the  2023  preliminary  results  announcement,  the 
Annual Report, the 2023 interim results announcement and 
the 2023 interim report. 

SIGNIFICANT ACCOUNTING MATTERS 

During  the  year,  the  Audit  Committee  considered  key 
accounting issues, judgements and disclosures in relation 
to the Financial Statements. The most significant of these 
was  the  risk  of  the  value  of  inventory,  the  carrying  value 
of investments and the value of goodwill at a Group level. 
The  Audit  Committee  also  received  communications 
from  management  and  the  external  auditor  on  a  number 
of  other  accounting  matters,  including  the  valuation  of 
mineral  reserves  and  resources,  revenue  recognition  and 
restoration provisions.

GOVERNANCE REPORT

Audit Committee 
Report

GOING CONCERN AND VIABILITY 

The  Audit  Committee  reviews  supporting  papers  from 
management to support the going concern and viability 
statements set out on page 179. This includes sensitivity 
analysis  over  key  assumptions.  Following  this  review, 
the  Audit  Committee  recommended  to  the  Board  the 
approval of both statements.

EXTERNAL AUDITOR 

The external auditor, PKF, attends meetings of the Audit 
Committee.  The  Audit  Committee  has  the  opportunity 
to meet with the external auditor without the executive 
directors being present to provide a forum to raise any 
matters of concern in confidence and together discusses 
and agrees the scope of the audit plan for the full year. 
The external auditor reports on the control environment 
in  the  Group,  key  accounting  matters  and  mandatory 
communications.  The  Audit  Committee  also  receives 
and reviews a report from the external auditor setting out 
to its satisfaction how its independence and objectivity 
is safeguarded when providing non-audit services. The 
value of non-audit services provided by PKF in respect 
of  the  year  ending  31  December  2023  amounted  to 
£600,000  for  due  diligence  and  transactional  services 
(2022:  £116,750,  principally  in  respect  of  tax  services 
and  due  diligence  and  transactional  services).  During 
the  year  there  were  no  circumstances  where  PKF  was 
engaged  to  provide  services  prohibited  by  the  FRC’s 
2019  ethical  standard  or  which  might  have  led  to  a 
conflict of interest.

The Audit Committee continues to be satisfied with the 
work of PKF and that they continue to remain objective 
and  independent.  Zahir  Khaki  is  serving  his  third  year  
as audit partner.

INTERNAL AUDIT 

The  Group  does  not  have  a  formal  internal  audit 
function  and  the  CFO  performs  a  number  of  activities 
that an internal audit function would perform. The Audit 
Committee  receive  regular  formal  updates  covering 
planned  activities,  findings  of  reviews  performed  and 
updates on agreed actions from previous reviews. The 
Audit Committee considers this is appropriate given the 
close involvement of the executive directors and senior 
management on a day-to-day basis. However, the need 
for an internal audit function will be kept under review by 
the Audit Committee on behalf of the Board. 

This  report  was  approved  by  the  Board  on  17  March 
2024.

The Remuneration Committee is responsible for: 

•  Determining and agreeing with the Board the framework 
or  broad  policy  for  the  remuneration  of  the  executive 
officers and other senior managers;   

• 

Taking into account all factors which it deems necessary 
including  the  level  of  the  Company’s  remuneration 
relative to other companies to ensure that members of 
the Company are provided with appropriate incentives 
to encourage enhanced performance and are, in a fair 
and  reasonable  manner,  rewarded  for  their  individual 
contributions to the success of the Company; and

•  Determining each year whether awards will be made, and 
if so, the overall amounts of such awards, the individual 
awards to executive directors and other senior executives 
and the performance targets to be used.  

2023  was  another  busy,  challenging  and  very  successful 
year  for  the  Group.  The  Group  was  able  to  deliver  further 
improved  profitability 
in  difficult  economic  conditions, 
whereby  volumes  declined  4%  LFL,  while  simultaneously 
delivering  on  a  series  of  bolt-on  acquisitions  and  the 
transformative agreements for the CRH Lime Acquisitions.

From  a  purely  financial  perspective,  in  2023,  the  Group 
delivered  revenue  of  £580.3  million,  underlying  EBITDA 
of  £116.7  million,  underlying  profit  before  tax  of  £71.2 
million  and  underlying  EPS  of  8.12p.  This  is  an  increase 
YoY  to  underlying  EPS  of  1%  and  exceeded  the  initial 
market consensus estimate of 7.3p by 11%, an exceptional 
achievement. The  Group  also  had  strong  cash  generation, 
closing  the  year  with  £55.9  million  which  kept  Covenant 
Leverage well below our long term target range of 2.0x.

The  Group  also  maintained  its  excellent  health  &  safety 
standards and delivered on the aforementioned bolt-on and 
transformative acquisitions.

2023 REMUNERATION OUTCOMES

In 2021 the Committee undertook a complete review of our 
remuneration  policy  in  conjunction  with  our  advisers,  and 
in consultation with certain Shareholders, to ensure it was 
appropriate  given  SigmaRoc’s  growth  to  date  combined 

Remuneration Committee Report

with  the  future  growth  and  development  ambition  of 
the  Group.  A  key  outcome  of  the  review,  and  which  was 
specifically  directed  by  input  from  Shareholders,  was  to 
measure  executive  director  bonuses  based  on  EPS,  rather 
than  EBITDA,  as  it  currently  provides  a  more  complete 
assessment of the Group’s financial performance.

As a result, annual bonuses have since been primarily based 
on  underlying  EPS with  additional performance  conditions 
pertaining to corporate objectives – this year focussing on 
delivery of the Group’s acquisition pipeline following the £30 
million fundraise in February 2023.

The  2023  underlying  EPS  targets  were  set  in  early  2023, 
following confirmation of market consensus estimates, and 
the maximum target set required an out performance relative 
to market expectations of 10% or more. At the outset of 2023 
the  market  consensus  estimates  for  the  Group’s  full  year 
EPS was 7.3p, therefore the maximum target was 8.0p. As 
noted in the 2023 business performance review, the Group 
performed  very  strongly  despite  numerous  challenges, 
achieving underlying EPS of 8.12p, being 1.5% ahead of the 
maximum target set and this measure, applying to 75% of 
the overall bonus, was therefore achieved in full.

The  remaining  25%  of  the  overall  bonus  pertained  to 
corporate  objectives,  and  this  year  was  focused  on 
execution  and  delivery  of  the  Group’s  investment  pipeline 
communicated as part of the Group’s £30 million fundraise 
in  February  2023.  This  measure  was  defined  based  on  a 
level of profit after tax added to the Group, with a lower limit 
of £2 million and an upper limit of £3 million, with the newly 
acquired businesses contributing over £3 million in FY23.

The  25%  of  the  overall  bonus  pertaining  to  corporate 
objectives was therefore achieved in full in 2023.

The  Committee  carefully  considered  whether  the  annual 
bonus  outcome  reflects  the  underlying  performance  of 
the  business,  as  well  as  the  experience  of  Shareholders 
and  other  stakeholders  during  the  year  and  whether  any 
discretion should be exercised. In doing so, the Committee 
specifically  considered  health  &  safety  performance  of 
the  Group,  factored  in  broader  financial  performance 
(revenue, EBITDA, EBITDA margins, free cash flow, CapEx 
and ROIC) and overall delivery of strategy. The Committee 
was  satisfied  that  the  bonus  outcome  was  fair,  and  no 
discretion was exercised.

2023 POLICY APPLICATION

For 2023, the Committee implemented the policy established 
in 2021 as follows:

•  Review  of  executive  director  salaries  to  ensure  they 
remain  commensurate,  taking  into  consideration  the 
inflationary  macroeconomic  environment  in  2022  and 
its  evolution  in  2023,  and  the  fact  that  the  executive 
directors  did  not  receive  any  adjustments  to  their 
salaries in 2022.

•  No change to benefits or pension arrangements.
• 

The annual bonus opportunity will continue to be 125% 
of  salary  for  executive  directors  and  be  based  at  75% 
of  underlying  EPS  and  25%  for  corporate  objectives, 
with suitable safety standards being maintained as an 
override.

•  Assessment  of 

to 
determine vesting of the initial PSP awards granted in 
October 2021.

SHAREHOLDERS’ AND EMPLOYEE’S VIEWS

We  are  very  grateful  for  the  views  received  from  major 
Shareholders  and  seek  to  engage  with  Shareholders  on 
a  continuous  basis  on  remuneration  matters.  I  can  be 
contacted via the Company Secretary should you have any 
questions on this report or more generally in relation to the 
Group’s approach to remuneration.

While  SigmaRoc  applies  the  QCA  Code,  the  Board 
considers the principles and provisions in the UK Corporate 
Governance  Code.  Under  the  main  code,  companies  are 
required to establish a mechanism for gathering the views 
of the workforce on all matters, including pay. The Board has 
considered carefully the most effective way of achieving this 
and has appointed its General Counsel, Anthony Brockbank, 
as  the  Group’s  workforce  representative,  reporting  to  the 
Board on all workforce engagement matters.

POLICY REPORT

PERFORMANCE MEASURED BENEFITS 

achievement of stretching performance targets and annual 
bonus may be reduced or eliminated if safety performance 
or accident records deteriorate or reach unacceptable levels.

Remuneration  performance  measures  are  selected  to 
align  with  the  Group’s  key  performance  indicators  and  the 
interests  of  Shareholders.  Performance  targets  are  set 
so  that  they  are  stretching  to  achieve  maximum  pay-out 
but  also  ensure  excessive  risk  exposure  is  mitigated.  The 
Remuneration  Committee  sets  targets  that  are  aligned 
with  the  Company’s  strategy  as  well  as  both  external 
expectations and the economic environment.

If  there  are  changing  circumstances,  such  as  material 
acquisitions  or  changes 
the 
Committee  retains  the  ability  to  adjust  or  amend 
performance  measures  and  targets  to  ensure  that  they 
are  relevant  and  to  ensure  they  still  incentivise  whilst 
minimising excessive risk exposure.

in  market  conditions, 

BASE SALARY 

Our  objective  is  to  provide  a  competitive  base  salary 
reflective  of  the  skills  and  experience  of  the  relevant 
individual. These  are  reviewed  annually  or  on  a  significant 
change  of  responsibilities  or  change  in  market  practice  or 
a  change  in  the  size  or  complexity  of  the  business.  The 
Remuneration Committee also takes into account external 
market data and pay and employment conditions elsewhere 
in  the  Group  and  industry  when  considering  increases 
to  base  salary  levels.  There  are  no  performance  criteria 
associated with receiving this benefit.

ANNUAL CASH BONUS

To  incentivise  the  delivery  of  annual  financial,  strategic 
and  safety  objectives,  executive  directors  and  senior 
management  may  participate 
in  the  annual  bonus 
scheme. The Remuneration Committee sets performance 
measures  and  targets  at  the  start  of  the  financial  year, 
or  later  if  appropriate,  and  based  on  the  performance, 
bonuses  are  paid  in  cash  shortly  after  the  completion  of 
the audit of the annual results.

The  executives’  annual  bonus  arrangements  are  focused 
on the achievement of the Company’s short- and medium-
term financial objectives, with financial measures selected 
to closely align the performance of the executive directors 
with the strategy of the business and with shareholder value 
creation.  Where  non-financial  objectives  are  set,  these  are 
chosen to support the delivery of the longer-term strategic 
milestones and which link to those KPIs of most relevance 
to each director’s individual responsibilities.

For  executive  directors,  the  maximum  opportunity 
is 
125%  of  salary. This  level  of  incentive  opportunity  reflects 
the  Committee’s  desire  to  retain  a  high  proportion  of 
remuneration on variable pay (which is not pensionable).

Financial measures will normally determine the majority or 
all of the bonus opportunity and the balance may be based 
on  non-financial,  strategic,  personal  and/or  ESG-related 
objectives.  Where  possible,  a  graduated  scale  of  targets 
is normally set for financial measures, with no pay-out for 
performance below a threshold level of performance.

Any  payment  is  discretionary  and  will  be  subject  to  the 

PERFORMANCE SHARE PLAN

In  conjunction  with  the  acquisition  of  Nordkalk  in  August 
2021,  a  Performance  Share  Plan  was  proposed  to  drive 
performance of the Group and delivery of the Group’s long-
term  objectives,  aid  retention  of  key  personnel  and  align 
directors’ interests with those of Shareholders.

The PSP, together with any other share incentive plan(s), is 
limited  to  no  more  than  10%  of  the  issued  ordinary  share 
capital of the Company over a ten-calendar year period.

The  initial  awards  under  the  Performance  Share  Plan 
(referend to henceforth as LTIP) were made to the executive 
directors  and  certain  senior  management,  with 
the 
allocations  determined  by  the  Remuneration  Committee. 
The LTIP is subject to meeting EPS growth and TSR criteria, 
with the first vesting attainable following the financial year 
ended 31 December 2023.

The  EPS  measure  is  based  on  growth  in  underlying  EPS 
over  the  performance  period. The  target  range  is  a  sliding 
scale set at the time of award, taking account of internal and 
external  forecasts,  to  encourage  continuous  improvement 
and incentivise the delivery of stretch performance.

The  TSR  measure  takes  the  total  return  received  by  the 
Group’s  Shareholders  in  terms  of  share  price  growth 
over  a  three-year  period  and  compares  it  with  the  total 
returns  received  by  shareholders  in  companies  within  a 
predetermined  and  appropriate  comparator  group.  The 
Remuneration Committee’s intention is to reward only TSR 
performance which outperforms the comparator group.

Subsequent  awards  may  be  granted  by  the  Remuneration 
Committee  within  six  weeks  following  the  Company’s 
announcement  of  its  financial  results  for  any  annual  or 
six month period. The Remuneration Committee may also 
grant awards at any other time when it considers there to 
be exceptional circumstances which justify the granting of 
awards (for example, in the case of recruitment).

An  employee  may  not  receive  such  subsequent  awards  in 
any  financial  year  in  respect  of  Ordinary  Shares  having  a 
market value in excess of 150% of their annual base salary 
in that financial year.

As  a  general  rule,  an  award  will  lapse  upon  a  participant’s 
the  Group,  with 
termination  of  employment  within 
certain  exceptions  permissible  solely  at  the  discretion 
of  the  Remuneration  Committee  (death,  injury,  ill-health, 
redundancy etc).

The  Performance  Share  Plan  and  the  LTIP  awards  were 
approved  by  Shareholders  at  a  general  meeting  of  the 
Company on 2 August 2021.

NEW OPTION PLAN

In connection with the CRH Lime Acquisitions, on 4 January 
2024  the  Company  adopted  the  New  Option  Plan  (to  be 
known  as  the  ‘SigmaRoc  plc  Share  Option  Plan  2023’)  in 
order to incentivise the executives and senior management 
of  the  Group  and  align  their  interests  with  those  of 
Shareholders.

GOVERNANCE REPORTSIGMAROC ANNUAL REPORT 2023Key terms of the New Option Plan are as follows:

OTHER BENEFITS 

169

•  Administration  and  eligibility:  The  Remuneration 
Committee administers the plan. Any Group employee, 
including  executive  directors,  can  participate  at  the 
Committee's discretion, with additional eligibility criteria 
for tax-qualified options.

•  Operation and terms: The plan will operate only once, 
granting  options  conditional  on  Admission  (being 
admission  of  the  enlarged  group  to  trading  on  AIM 
on  4  January  2024)  as  a  one-off  in  connection  with 
the proposals. It's not expected that future grants will 
be  made  under  this  plan  unless  deemed  exceptional 
by  the  Remuneration  Committee.  No  payment  is 
required for the grant of these options, which are not 
transferable except upon death or with Remuneration 
Committee consent.

•  Grant  details:  New  options  have  been  granted  for  a 
total of 56,373,757 Ordinary Shares, representing 5.1% 
of  the  Company’s  issued  share  capital  upon  grant. 
The  final  amount  granted  under  the  New  Option  Plan 
is  higher  than  what  was  published  in  the  Admission 
Document, however executive director allocations have 
not  changed,  as  the  Admission  Document  figure  had 
not taken into account the change in the placing price 
and resultant increase in Ordinary Shares. The exercise 
price is set at 60 pence per option, vesting equally on 
the  third,  fourth  and  fifth  anniversaries  of  Admission 
and remaining exercisable until the tenth anniversary.

•  Plan  limits:  The  plan  operates  within  the  Company's 
existing  10%  dilution  limits  over  a  ten-year  period, 
including  new  issue,  treasury  or  market-purchased 
Ordinary Shares.

•  Timing  of  grants:  New  options  are  to  be  granted 
immediately following Admission, with no further grants 
planned unless under exceptional circumstances.

•  Corporate events and leaving employment: Provisions 
detail  how  options  are  affected  by  corporate  changes 
or  employment  termination,  allowing  for  early  vesting 
or adjustments in certain scenarios.

•  Malus  and  clawback:  The  Remuneration  Committee 
may apply these provisions for material misstatements 
of  financial  results,  errors,  misconduct,  corporate 
failure,  or  reputational  damage,  affecting  unexercised 
options or requiring repayment of shares received.

•  Participants’  rights  and  shares:  New  options  don't 
confer  shareholder  rights  until  exercised,  and  shares 
allotted will rank equally with existing shares except for 
prior record date rights.

•  Amendments  and  termination:  The  plan  can  be 
amended  by 
the  Remuneration  Committee  with 
participant  and  shareholder  consent  under  certain 
conditions, ensuring no adverse changes to participant 
terms  without  majority  consent  and  maintaining 
compliance  with 
the  employees'  share  scheme 
definition under the Companies Act 2006.

PENSION 

Pensions  are  provided  to  aid  recruitment  and  retention  by 
allowing the executive directors to make provision for long-
term retirement benefits. These are comparable with similar 
roles in similar companies. Executive directors are currently 
entitled to receive 10 per cent of their base salary. There are 
no performance criteria associated with receiving this benefit. 

The  Group  also  provides  competitive  and  cost-effective 
benefits  that  may 
insurance, 
car  allowance,  employee  benefits 
insurance  and  the 
reimbursement  of  certain  travel  costs.  There  are  no 
performance criteria associated with receiving these benefits.

include  private  medical 

All  our  UK  employees,  over  500,  have  been  offered  both 
private  medical  insurance  and  group  life  assurance.  Our 
benefits provider commented that the uptake of this offering 
from our employees was unprecedented, with many adding 
family members. 

SigmaRoc has also engaged Link Group to set up a share 
incentive plan for all UK employees, an offering we already 
have in the Channel Islands. Under the terms of the SIP, each 
eligible  employee  can  contribute  from  salary  to  purchase 
Ordinary  Shares.  We  are  continuing  to  investigate  share 
plans for our European operations.

NON-EXECUTIVE DIRECTORS

Non-executive  directors  each  receive  a  market  rate  basic 
fee, subject to time commitment requirements, for holding 
the office of non-executive director which is set by the Board 
as a whole.

Non-executive directors do not participate in any incentive 
scheme,  share  scheme  or  pension  arrangement  (except 
for  minimum  statutory  requirements),  but  may  be  eligible 
to  receive  benefits  such  as  the  use  of  secretarial  support, 
travel costs or other benefits that may be appropriate.

SERVICE AGREEMENTS / LETTERS OF APPOINTMENT 
OF DIRECTORS AND LOSS OF OFFICE

Each  of  the  directors  has  a  service  agreement  or  letter  of

NOTICE PERIODS AND PAYMENTS IN LIEU OF NOTICE

The  maximum  notice  period  for  executive  directors  is 
12  months,  however  the  Committee  retains  the  right  to 
terminate  an  executive  director’s  service  agreement  by 
making a payment in lieu of notice. The payment will include 
salary, cost of benefits and loss of pension provision for the 
notice period (or the unexpired portion of it).

In  appropriate  circumstances,  other  payments  may 
also  be  made,  such  as  in  respect  of  accrued  holiday  and

RECRUITMENT POLICY

The Remuneration Committee will seek to ensure that when 
appointing  a  new  executive  director,  their  remuneration 
arrangements are in the best interests of the Company, and 
not more than is appropriate. The Committee will determine 
a new executive director’s remuneration package in line with 
the policy set out above, however discretionary awards may 
be made in appropriate circumstances, such as: 

•  An  interim  appointment  to  fill  a  role  on  a  short-term 

basis;

•  Provide relocation, travel and subsistence payments;

•  Reflect  remuneration  arrangements  provided  by  a 

previous employer; and

•  Reimbursement of costs incurred as a consequence of 

resigning from their previous employment.

EXTERNAL APPOINTMENTS FOR EXECUTIVE DIRECTORS

The  Company  recognises  that  its  executive  directors  may 
be  invited  to  become  non-executive  directors  of  other 
companies.  Such  non-executive  duties  can  broaden  a 
director’s  experience  and  knowledge  which  can  benefit 
SigmaRoc.  Subject  to  approval  by  the  Board,  executive 
directors are allowed to accept non-executive appointments, 
provided  that  these  appointments  are  not  likely  to  lead  to 
conflicts  of  interest,  and  the  Committee  will  consider  its 
approach to the treatment of any fees received by executive 
directors in respect of non-executive roles as they arise.

CONSIDERATION OF SHAREHOLDERS’ VIEWS

The  Committee  is  committed  to  an  ongoing  dialogue 
with  Shareholders  and  welcomes  feedback  on  directors’ 
remuneration.  The  Committee  seeks  to  engage  directly 
with  major  Shareholders  and  their  representative  bodies 
on  changes  to  the  policy.  The  Committee  will  also 
consider  Shareholder  feedback  received  in  relation  to  the 

remuneration-related  resolution  to  be  put  forward  at  this 
year’s  AGM.  This,  together  with  any  additional  feedback 
received  from  time  to  time  (including  any  updates  to 
Shareholders’ remuneration guidelines), is then considered 
as  part  of  the  Committee’s  annual  review  of  remuneration 
policy and its implementation.

In its 2021 review of executive remuneration the Committee 
conducted  a  comprehensive  consultation  exercise  which 
elicited feedback from the Company’s largest Shareholders. 
The  Committee  was  very  grateful  for  the  views  received. 
The  feedback,  which  was 
largely  positive,  was  used 
constructively to shape our remuneration arrangements.

CONSIDERATION OF EMPLOYMENT CONDITIONS 
ACROSS THE GROUP

The  Committee  closely  monitors  the  pay  and  conditions 
of  the  wider  workforce,  and  the  design  of  the  directors’ 
remuneration policy is informed by the policy for employees 
across the Group.

While employees are not formally consulted on the design 
of the directors’ remuneration policy, the Board will receive 
views through our designated workforce representative on a 
variety of areas including pay.

DIFFERENCES IN PAY POLICY FOR EXECUTIVE 
DIRECTORS COMPARED TO EMPLOYEES

As  for  the  executive  directors,  general  practice  across  the 
Group is to recruit employees at competitive market levels 
of remuneration, incentives and benefits to attract and retain 
employees,  accounting  for  national  and  regional  talent 
pools.  When  considering  salary  increases  for  directors, 
the  Committee  considers  salary  increases  and  pay  and 
employment  conditions  across  the  wider  workforce.  The 
pension  contribution  for  executive  directors  is  consistent 
with that for the general workforce. Senior employees can 
earn annual bonuses for delivering exceptional performance, 
with  corporate  performance  measures  aligned  to  those 
set  for  the  executive  directors.  All  UK  based  employees, 
including  the  executive  directors,  have  the  opportunity  to 
participate in the tax-approved share incentive plans.

There  are  some  differences 
in  the  structure  of  the 
remuneration  policy  for  the  executive  directors  compared 
to that for other employees within the organisation, which 
the Committee believes are necessary to reflect the differing 
levels  of  seniority  and  responsibility.  At  senior  levels, 
remuneration is increasingly long-term, and ‘at risk’ with an 
increased emphasis on performance-related pay and share- 
based remuneration. This ensures the remuneration of the 
executives is aligned with both the long-term performance 
of the Company and the interests of Shareholders.

ANNUAL BONUS FOR 2023

The annual bonus opportunity for each executive director was 125% of base salary (pro-rated for service). The 2023 annual bonus 
was based on the achievement of stretching underlying EPS targets for 75% with the remaining 25% based on corporate objectives.

Remuneration Committee Report

Reflecting the strong financial performance of the Group in 
a  challenging  year,  the  earnings  outcome  for  the  year  was 
ahead of the maximum EPS target of 8.0p. As a result, the EPS 
measure was achieved in full. Based on a bonus opportunity 
of 125% of base salary, and a 75% weighting against the EPS 
condition,  performance  against  this  measure  delivered  a 
bonus outcome of 93.75% of base salary.

Corporate objectives (25% of the total bonus)

The  remaining  25%  of  the  overall  bonus  pertained  to 
corporate  objectives,  and  this  year  was  focused  on 
execution and delivery of the Group’s investment pipeline 
communicated as part of the Group’s £30 million fundraise 
in  February  2023.  This  measure  was  defined  based  on  a 
level of profit after tax added to the Group in the year, with 
a lower limit of £2 million and an upper limit of £3 million, 
with  the  newly  acquired  businesses  contributing  over  £3 
million in FY23.

The  25%  of  the  overall  bonus  pertaining  to  corporate 
objectives was therefore achieved in full in 2023.

Overall, the bonus outcome for the year, taking into account 
financial  performance  and  the  delivery  of  corporate 
objectives, was 100% of the maximum.

The  overall  bonus  for  the  period  in  service  as  a  director 
was as follows:

David Barrett  

– 125% of base salary

Max Vermorken   – 125% of base salary

Garth Palmer  

– 125% of base salary

The  Remuneration  Committee  believes  these  outcomes 
fairly reflect the performance of the business over the 2023 
financial year.

PERFORMANCE SHARE PLAN

The LTIP was granted under the PSP in October 2021, with 
awards vesting subject to a performance condition based on 
underlying EPS growth for the year ending 31 December 2023 
and TSR over a three year period relative to the AIM 100 index.

to  consider 

The  Remuneration  Committee  met 
the 
performance of the executive management team in relation 
to  the  performance  conditions  set  within  the  LTIP.  The 
Committee has concluded that the management team has 
delivered  above  expected  performance  in  relation  to  the 
EPS performance condition as defined in the LTIP, reaching 
8.12p for the year 2023. As a result of this performance, the 
Remuneration Committee considers the EPS performance 
condition  of  the  LTIP  as  satisfied  for  the  year  ended  31 
December 2023. Consequently, Part I awards are expected 
to vest on 31 August 2024, Part II on 31 August 2025 and 
Part III on 31 August 2026.

TSR  will  be  assessed  based  on  the  average  of  the  three

GOVERNANCE REPORTSIGMAROC ANNUAL REPORT 2023In 2022 the Committee introduced a minimum shareholding guideline for executive directors, whereby they are expected to 
build and maintain a shareholding equivalent to 75% of their base salary. Current holdings of Ordinary Shares by the executive 
directors represent cash investments made by them into the Company and no Ordinary Shares that they currently hold have 
been granted to them by the Company in connection with their employment. When that changes the Committee will reassess 
the minimum shareholding guideline and revise accordingly.

workforce  salaries  and  wages.  While  severity  of,  and 
responses  to,  cost-of-living  increases  varied  by  country 
across  the  Group,  the  Committee  was  satisfied  that  the 
changes implemented to date, and where applicable, those 
that were proposed, were fair and reasonable.

Non-Executive Directors’ Fees 

The basic fee for the non-executive directors for 2023 was 
£50,000. For 2024 it is proposed that NEDs be paid a basic 
fee  of  £70,000,  representing  the  substantial  growth  and 
development of the Group over the past 12 months.

Annual bonus

For 2024, the executive directors will have the opportunity to 
earn a bonus of up to 125% of their base salary. The bonus 
will be subject to stretching performance conditions based 
on underlying EPS (75%) and corporate objectives (25%). The 
performance  targets  contain  confidential  information  and 
so are not disclosed on a prospective basis. The Committee 
propose  to  disclose  the  targets,  and  performance  against 
them, retrospectively as was the case in 2023.

1 Including £15k car allowance which now forms part of base

PSP AWARDS

The Committee also undertook a review of salaries across 
the  broader  Group  toward  the  end  of  2023  to  ensure  they 
remain  commensurate,  particularly  given  recent  global 
inflationary  trends  and  resulting  cost  of  living  pressures. 
Inflation  rates  by  country,  across  multiple  reference  dates, 
were compared to recent and proposed changes to Group 

The Committee does not expect to grant any further awards 
under the PSP in 2024.

Shares  in  AIM  quoted  trading  companies  or  a  holding 
company  of  a  trading  group  may,  after  a  2  year  holding 
period,  qualify  for  Business  Property  Relief  for  United 
Kingdom  inheritance  tax  purposes,  subject  to  the  detailed 
conditions for the relief. 

Investors should note that Business Property Relief would 
cease  to  be  available  in  the  event  that  the  Company’s

stock  exchange,  for  example  the  Main  Market  of  the 
London Stock Exchange.

By  being  responsible  for  their  own  businesses,  that  are 
aligned  with  the  overall  Group’s  strategy,  employees  are 
fully  aware  of  their  impact  and  contribution  as  they  are 
inherently  responsible  for  their  own  success.  The  Group 
and  each  business  is  committed  to  employing  the  best 
they can, not only in skills and competence but also in their 
softer skills, regardless of who they are or where they have 
come from. Once engaged, each employee is nurtured and 
developed locally with opportunities within each business 
and platform offered openly.

ANNUAL GENERAL MEETING 

The  AGM  will  be  held  at  the  Washington  Mayfair  Hotel,  5 
Curzon St, London W1J 5HE on 12 April 2024 at 12:30pm. 
The  formal  notice  convening  the  AGM,  together  with 
explanatory  notes  on  the  resolutions  contained  therein, 
is  included  in  the  separate  circular  accompanying  this 
document  and  is  available  on  the  Company’s  website  at 
www.sigmaroc.com. 

VIABILITY STATEMENT 

The Directors have assessed the viability of the Group over 
a  period  to  December  2027.  This  is  the  same  period  over 
which  financial  projections  were  prepared  for  the  Group’s 
strategic  financial  plan.  In  making  their  assessment  the 
Directors  have  taken  into  account  the  Group’s  current 
position and the potential impact of the principal risks and 
uncertainties set out on pages 132 to 137 on its business 
model, future performance, solvency or liquidity. They also 
stress tested their analysis by running a number of credible 
scenarios  and  considered  the  availability  of  mitigating 
actions.  Based  on  this  assessment,  the  Directors  confirm 
that they have a reasonable expectation that the Group will 
be  able  to  continue  in  operation  and  meet  its  liabilities  as 
they fall due over the period to 31 December 2024. In making 
this statement, the Directors have assumed that financing 
remains available and that mitigating actions are effective. 

CORPORATE RESPONSIBILITY

Environmental 

SigmaRoc  undertakes  its  activities  in  a  manner  that 
minimises  or  eliminates  negative  environmental  impacts 
and maximises positive impacts of an environmental nature.

Health and safety

SigmaRoc  operates  a  comprehensive  health  and  safety 
programme  to  ensure  the  wellness  and  security  of  its 
employees. The control and eventual elimination of all work-
related  hazards  require  a  dedicated  team  effort  involving 
the active participation of all employees. A comprehensive 
health  and  safety  programme  is  the  primary  means  for 
delivering best practices in health and safety management. 
This  programme 
incorporate 
employee suggestions, lessons learned from past incidents 
and  new  guidelines  related  to  new  projects,  with  the  aim 
of  identifying  areas  for  further  improvement  of  health  and 
safety management. This results in continuous improvement 
of the health and safety programme. Employee involvement 
is  regarded  as  fundamental  in  recognising  and  reporting 
unsafe  conditions  and  avoiding  events  that  may  result  in 
injuries and accidents. 

is  regularly  updated  to 

Internal controls

The Board recognises the importance of both financial and 
non-financial controls and has reviewed the Group’s control 
environment and any related shortfalls during the year. Since 
the Group was established, the Directors are satisfied that, 
given the current size and activities of the Group, adequate 
internal  controls  have  been  implemented.  Whilst  they  are 
aware  that  no  system  can  provide  absolute  assurance 

179

against material misstatement or loss, in light of the current 
activity  and  proposed  future  development  of  the  Group, 
continuing reviews of internal controls will be undertaken to 
ensure that they are adequate and effective.

Further details of corporate governance can be found in the 
Corporate Governance Report on page 156.

Going concern

The  Group  meets  its  day-to-day  working  capital  and  other 
funding  requirements  through  cash  and  banking  facilities, 
which were renewed in November 2023 and of which more 
information can be found on page 203.

The  Directors  have  a  reasonable  expectation  that  the 
Group has adequate resources to continue in operational 
existence for the foreseeable future and, therefore, continue 
to adopt the going concern basis in preparing the Annual 
Report and Financial Statements. Further details on their 
assumptions  and  their  conclusion  thereon  are  included  
in the statement on going concern included in Note 2.3 to 
the Financial Statements.

Directors’ and officers’ indemnity insurance

The  Company  has  made  qualifying  third-party  indemnity 
provisions for the benefit of its Directors and officers. These 
were made during the year and remain in force at the date 
of this Annual Report.

EVENTS AFTER THE REPORTING PERIOD

Events after the reporting period are set out in Note 38 to the 
Financial Statements.

POLICY AND PRACTICE ON PAYMENT OF CREDITORS

The  Group  agrees  terms  and  conditions  for  its  business 
transactions  with  suppliers.  Payment  is  then  made  in 
accordance  with  these  terms,  subject  to  the  terms  and 
conditions  being  met  by  the  supplier.  As  at  31  December 
2023,  the  Company  had  an  average  of  53  days  (2022:  54 
days)  purchases  outstanding  in  trade  payables  and  the 
Group had an average of 62 days (2022: 58 days).

FUTURE DEVELOPMENTS

Details of future developments for the Group are disclosed 
in  the  Chairman’s  Statement  on  page  14  and  the  CEO’s 
Strategic Report on page 18.

PROVISION OF INFORMATION TO AUDITOR

So  far  as  each  of  the  Directors  is  aware  at  the  time  this 
report is approved:

• 

• 

there  is  no  relevant  audit  information  of  which  the 
Group's auditor is unaware; and

the  Directors  have  taken  all  steps  that  they  ought  to 
have taken to make themselves aware of any relevant 
audit  information  and  to  establish  that  the  auditor  is 
aware of that information.

AUDITOR

PKF Littlejohn LLP has signified its willingness to continue 
in office as auditor.

181

The  Directors  are  responsible  for  preparing 
the  Financial 
the  Annual  Report  and 
Statements  in  accordance  with  applicable 
law and regulations, including the AIM Rules 
for Companies.

Company  law  requires  the  Directors  to  prepare  financial 
statements  for  each  financial  year.  Under  that  law  the 
Directors have elected to prepare the Group and Company 
in  accordance  with  UK-adopted 
Financial  Statements 
IAS). 
International  Accounting  Standards  (UK-adopted 
Under  company  law  the  Directors  must  not  approve  the 
Financial  Statements  unless  they  are  satisfied  that  they 
give a true and fair view of the state of affairs of the Group 
and  Company,  and  of  the  profit  or  loss  of  the  Group  for 
that  period.  In  preparing  these  Financial  Statements,  the 
Directors are required to:

• 

select suitable accounting policies and then apply them 
consistently;

•  make  judgments  and  accounting  estimates  that  are 

reasonable and prudent; 

• 

state  whether  applicable  UK-adopted  IAS  have  been 
followed, subject to any material departures disclosed 
and explained in the financial statements; and

• 

prepare the financial statements on the going concern 
basis  unless  it  is  inappropriate  to  presume  that  the 
Group will continue in business.

The  Directors  are  responsible  for  keeping  adequate 
accounting records that are sufficient to show and explain 
the Group’s and Company’s transactions and disclose with 
reasonable  accuracy  at  any  time  the  financial  position  of 
the  Group  and  Company  and  enable  them  to  ensure  that 
the  Financial  Statements  comply  with  the  Companies 
Act  2006. They  are also responsible for safeguarding the 
assets  of  the  Group  and  Company,  and  hence  for  taking 
reasonable steps for the prevention and detection of fraud 
and other irregularities.

The  Directors  are  responsible  for  the  maintenance  and 
integrity of the corporate and financial information included 
on the Company’s website, www.sigmaroc.com. Legislation 
in  the  United  Kingdom  governing  the  preparation  and 
dissemination of the Financial Statements may differ from 
legislation in other jurisdictions. 

The Company is compliant with AIM Rule 26 regarding the 
Company’s website.

The  Directors  confirm  that  they  have  complied  with  the 
above requirements in preparing the Financial Statements.

•  Obtaining  cashflow 

forecasts  covering  at 

least 
a  twelve-month  period  from  the  approval  of  the 
financial  statements,  ascertaining  the  key 
inputs 
and  assumptions  in  the  preparing  of  this  forecast/
budget  and  assessing  the  reasonableness  of  such 
assumptions; 

•  Comparing previous forecasts to actual performance to 

assess management’s forecasting accuracy; 

•  Agreeing the key inputs to the forecasts and/or budgets 

to the underlying supporting documentation;

•  Agreeing  the  year-end  cash  balances  to  the  opening 
working  capital  position  within  the  forecasts  and/or 
budgets;

• 

Testing  the  mathematical  accuracy  of  the  forecasts 
including stress testing the key inputs and assumptions; 
and

•  Reviewing  of  external  market  factors  affecting  the 
Group  and  the  Company  and  their  future  economic 
viability, such as the energy transition, and ensuring they 
are appropriately reflected in management’s forecasts.  

The  risks  that  we  considered  most  likely  to  affect  the 
financial resources or ability to continue operations over the 
going concern assessment period were:

• 

• 

• 

• 

adverse circumstances impacting timely conversion of 
trade receivables to cash;

the  ability  of  the  Group  and  Company  to  comply  with 
debt covenants;

rising  inflation  impacting  expenditures,  cost  of  sales 
and operating cashflows; and

the failure to achieve forecasted revenue growth. 

We  considered  these  risks  through  a  review  of  the 
application of reasonably foreseeable downside scenarios. 
We  found  the  going  concern  disclosure  in  note  2.3  to  be 
appropriate  as  it  gives  a  reasonable  description  of  the 
assessment of going concern supported by the underlying 
cashflow forecasts reviewed as part of our work in this area. 

Based on the work we have performed, we have not identified 
any  material  uncertainties  relating  to  events  or  conditions 
that,  individually  or  collectively,  may  cast  significant  doubt 
on the Group's or Company’s ability to continue as a going 
concern for a period of at least twelve months from when 
the financial statements are authorised for issue.

Our responsibilities and the responsibilities of the directors 
with respect to going concern are described in the relevant 
sections of this report.

OPINION 

We have audited the financial statements of SigmaRoc plc 
(the ‘Company’) and its subsidiaries (the ‘Group’) for the year 
ended 31 December 2023 which comprise the Consolidated 
Income  Statement, 
the  Consolidated  Statement  of 
Comprehensive  Income,  the  Consolidated  and  Company 
Statements  of  Financial  Position,  the  Consolidated  and 
Company Statement of Changes in Equity, the Consolidated 
and  Company  Cash  Flow  Statements  and  notes  to  the 
financial  statements, 
including  significant  accounting 
policies.  The  financial  reporting  framework  that  has  been 
applied  in  their  preparation  is  applicable  law  and  UK-
adopted international accounting standards and as regards 
the  parent  company  financial  statements,  as  applied  in 
accordance with the provisions of the Companies Act 2006. 

In our opinion: 

• 

• 

• 

• 

the financial statements give a true and fair view of the 
state of the Group’s and of the Company’s affairs as at 
31 December 2023 and of the Group’s profit for the year 
then ended; 

the  Group  financial  statements  have  been  properly 
prepared in accordance with UK-adopted international 
accounting standards;

the Company financial statements have been properly 
prepared in accordance with UK-adopted international 
accounting  standards  and  as  applied  in  accordance 
with the provisions of the Companies Act 2006; and

the  financial  statements  have  been  prepared 
in 
accordance  with  the  requirements  of  the  Companies 
Act 2006. 

BASIS FOR OPINION 

We  conducted  our  audit  in  accordance  with  International 
Standards  on  Auditing  (UK)  (ISAs  (UK))  and  applicable 
law. Our responsibilities under those standards are further 
described  in  the  Auditor’s  responsibilities  for  the  audit 
of  the  financial  statements  section  of  our  report.  We  are 
independent of the Group and Company in accordance with 
the ethical requirements that are relevant to our audit of the 
financial  statements  in  the  UK,  including  the  FRC’s  Ethical 
Standard as applied to listed entities, and we have fulfilled 
our  other  ethical  responsibilities  in  accordance  with  these 
requirements.  We  believe  that  the  audit  evidence  we  have 
obtained is sufficient and appropriate to provide a basis for 
our opinion. 

CONCLUSIONS RELATING TO GOING CONCERN 

In auditing the financial statements, we have concluded that 
the directors’ use of the going concern basis of accounting 
in the preparation of the financial statements is appropriate. 
Our evaluation of the directors’ assessment of the Group’s 
and  Company’s  ability  to  continue  to  adopt  the  going 
concern basis of accounting included:

•  Obtaining the directors’ going concern assessment and 
evaluating the appropriateness of this assessment;

of  materiality.  We  set  certain  quantitative  thresholds  for 
materiality. These, together with qualitative considerations, 

helped us to determine the scope of our audit and the nature, 
timing and extent of our audit procedures on the individual 
financial  statement  line  items  and  disclosures  and  to 
evaluate the effect of misstatements, both individually and 
in aggregate, on the financial statements as a whole.

Group financial statements

Company financial statements 

Materiality for the 
financial statements 
as a whole (‘overall 
materiality’) 

£5.80 million

(2022: £5.20 million)

£3.30 million

(2022: £3.00 million)

Basis of materiality

1% (2022: 0.97%) of turnover 

1% (2022: 0.86%) of net assets 

Rationale Benchmark

We considered revenue to be the most relevant 
performance indicator of the Group as it is a 
significant driver of profit or loss for the year. 

The  Company  operates  primarily  as  a 
holding  company  which  holds  the  main 
debt  facility  for  the  Group  and  as  such,  we 
consider net assets as the key metric. 

Rationale Percentage

The percentage applied to the benchmark has been selected to bring into scope all significant classes 
of transactions, account balances and disclosures relevant for the shareholders, and also to ensure 
that matters that would have a significant impact on the results were appropriately considered.

Performance materiality

£4.06 million

70% (2022: 70%) of 
overall materiality

(2022: £3.64 million)

£2.31 million

(2022: £2.10 million)

In determining performance materiality, we considered the following factors:

the number and quantum of identified misstatements in the prior year audit;

• 
•  management’s attitude to correcting misstatements identified;
• 

our  cumulative  knowledge  of  the  Group  and  Company  and  their  environment,  including 
industry specific trends;

• 
• 
• 

the consistency in the level of judgement required in key accounting estimates; 

the stability in key management personnel; and 

the level of centralisation in the Group’s financial reporting controls and processes.

We use performance materiality to reduce to an appropriately 
low level the probability that the aggregate of uncorrected 
and undetected misstatements exceeds overall materiality. 
Specifically, we use performance materiality in determining 
the  scope  of  our  audit  and  the  nature  and  extent  of  our 
testing  of  account  balances,  classes  of  transactions  and 
disclosures, for example in determining sample sizes.

For each significant component in the scope of our audit, we 
allocated  a  materiality  based  on  the  maximum  aggregate 
component  materiality.  The  range  of  materiality  allocated 
across components was between £4.50 million and £1.90 
million  (2022:  between  £3.30  million  and  £2.00  million). 
Materiality  for  material  non-significant  components  of 
£3.14 million (2022: £2.86 million) was calculated based on 
a percentage of the Group’s revenue.

We agreed with the Audit Committee that we would report 
to  them  misstatements  identified  during  our  audit  above 
£290,000 (2022: £260,000) as well as misstatements below 

those  amounts  that,  in  our  view,  warranted  reporting  for 
qualitative reasons.

OUR APPROACH TO THE AUDIT

In  designing  our  audit,  we  determined  materiality,  as 
above,  and  assessed  the  risk  of  material  misstatement 
in  the  financial  statements.  In  particular,  we  looked  at 
areas 
involving  significant  accounting  estimates  and 
judgement  by  the  directors  and  considered  future  events 
that  are  inherently  uncertain.  We  note  that  the  Group  has 
made  acquisitions  of  subsidiary  undertakings  and  has 
performed  a  purchase  price  allocation  during  the  year 
on  the  goodwill  asset  recognised  in  the  prior  year.  Both 
of  these  areas  are  inherently  complicated  and  require  a 
significant amount of judgement by management. We also 
addressed  the  risk  of  management  override  of  internal 
controls,  including  evaluating  whether  there  was  evidence 
of bias by management that represented a risk of material 
misstatement due to fraud.

GOVERNANCE REPORTSIGMAROC ANNUAL REPORT 2023Of  the  Group’s  41  components,  including  the  Company,  5 
material  and  significant  components  were  subject  to  full 
scope  audits  for  group  purposes,  a  targeted  scope  review 
was  performed  on  a  further  19  components  assessed  as 
material,  and  the  remaining  components  were  subject  to 
analytical review as they were not significant or material to 
the Group.

The components not subject to full scope audits contained 
only balances that eliminated on consolidation, or specific 
balances material to the financial statements. The Company 
was audited separately to the materiality level noted above.

Of  the  5  material  and  significant  components,  3  were 
located  in  Finland,  Sweden,  and  Poland.  The  components 
in these locations were audited by firms outside of the PKF 
network  operating  under  our  instruction.  The  remaining 
components were located in London, where the audit work 
was conducted by us using a team with specific experience 
of  auditing  companies  within  the  natural  resources  sector 
and publicly listed entities. We interacted regularly with the 

185

component audit teams during all stages of the audit and 
we were responsible for the scope and direction of the audit 
process.  This,  in  conjunction  with  additional  procedures 
performed, gave us appropriate evidence for our opinion on 
the Group and Company financial statements.

KEY AUDIT MATTERS 

Key audit matters are those matters that, in our professional 
judgment,  were  of  most  significance  in  our  audit  of  the 
financial  statements  of  the  current  period  and  include  the 
most  significant  assessed  risks  of  material  misstatement 
(whether or not due to fraud) we identified, including those 
which had the greatest effect on: the overall audit strategy, 
the  allocation  of  resources  in  the  audit;  and  directing  the 
efforts  of  the  engagement  team.  These  matters  were 
addressed  in  the  context  of  our  audit  of  the  financial 
statements as a whole, and in forming our opinion thereon, 
and we do not provide a separate opinion on these matters.  

Key Audit Matter

How our scope addressed this matter

Valuation and Allocation of Investments 
in subsidiary undertakings (Company) 
(Note 18)

The Company carries an “Investment 
in subsidiary undertakings” balance of 
£567.31 million (2022: £583.42 million) in 
its Statement of Financial Position.

There is a risk that the carrying value 
of the investments is greater than the 
recoverable amount and is therefore 
impaired.

We have assessed this to be a key audit 
matter as the estimated recoverable 
amount of investments is subjective 
due to inherent uncertainties involved 
in forecasting and discounting future 
cashflows, and thereby overstating the 
carrying value of investments.

Our work in this area included:

•  Obtaining the impairment models and assessment for each subsidiary and 

reviewing the models for reasonableness;

•  Assessing the mathematical accuracy of the models;
• 

For all key assumptions and inputs to the impairment models:  

• 
• 

• 

discussing their appropriateness with management. 

agreeing  to  supporting  evidence  including,  where  possible,  to 
third party data; and 

evaluating and recalculating the discount rate used;  

•  Reviewing  the  value  of  the  net  investment  in  subsidiaries  against  the 

supporting underlying assets;

•  Assessing  the  historical  forecasting  accuracy,  by  comparing  previously 

forecasted cash flows to actual results achieved;

•  Performing a sensitivity analysis on the key assumptions and inputs noted 

above; 

•  Considering the existence of impairment indicators per IAS 36 Impairment 

of Assets; and

•  Reviewing  the  associated  disclosures  in  the  financial  statements  and 

assessing the appropriateness of such disclosures.

Independent Auditor’s report to the members 
of SigmaRoc plc

Valuation and Allocation of Goodwill 
(Note 17)

The Group carries a balance of over 
£170.34 million (2022: £147.74 
million restated) in goodwill relating 
to the acquisition of its subsidiaries. 
Furthermore, in accordance with 
group’s accounting policy on business 
acquisitions and pending the finalisation 
of the Purchase Price Allocation (PPA) 
report, provisional goodwill is allocated 
to other identifiable assets and any 
unallocated amount  sits within goodwill.

In accordance with IAS 36, goodwill is 
not amortised; however, an impairment 
review should be undertaken annually, 
or more frequently, should events or 
changes in circumstances indicate a 
potential impairment. 

Goodwill is allocated to groups of 
cash generating units according to the 
level at which management monitors 
the operating segments. As such, the 
impairment reviews are performed 
in conjunction with the respective 
investment reviews.

We have assessed this to be a key 
audit matter given that the estimated 
recoverable amount of goodwill is 
subjective, including the estimates 
and judgements when calculating 
the recoverable amount, and as such 
there is a risk that the carrying value of 
goodwill may be overstated.

Our work in this area included:

•  Using  our  valuation  team,  who  are  part  of  our  audit  team,  to  review  the 
PPA prepared by a third party engaged by management. The work included 
reviewing the PPA and assessing the key assumptions and inputs used to 
allocate the goodwill value to other intangible assets;

•  Obtaining the impairment models and assessment for each subsidiary and 

reviewing the models for reasonableness;

•  Assessing the mathematical accuracy of the models;
• 

For all key assumptions and inputs to the impairment models: 

• 
• 

• 

discussing their appropriateness with management; 

agreeing  them  to  supporting  evidence  and  where  possible,  to 
third party data; and 

evaluating and recalculating the discount rate used; 

•  Assessing  the  historical  forecasting  accuracy,  by  comparing  previously 

forecasted cash flows to actual results achieved;

•  Performing a sensitivity analysis on the key assumptions and inputs noted 

above; 

•  Considering the existence of impairment indicators per IAS 36 Impairment 

of Assets; and

•  Reviewing  the  associated  disclosures  in  the  financial  statements  and 

assessing the appropriateness of such disclosures.

OTHER INFORMATION

The other information comprises the information included 
in the annual report, other than the financial statements and 
our  auditor’s  report  thereon. The  directors  are  responsible 
for the other information contained within the annual report. 
Our opinion on the Group and Company financial statements 
does  not  cover  the  other  information  and,  except  to  the 
extent  otherwise  explicitly  stated  in  our  report,  we  do  not 
express  any  form  of  assurance  conclusion  thereon.  Our 
responsibility is to read the other information and, in doing 
so,  consider  whether  the  other  information  is  materially 
inconsistent with the financial statements or our knowledge 
obtained  in  the  course  of  the  audit,  or  otherwise  appears 
to  be  materially  misstated.  If  we  identify  such  material 
inconsistencies or apparent material misstatements, we are 
required to determine whether this gives rise to a material 
misstatement  in  the  financial  statements  themselves.  If, 
based  on  the  work  we  have  performed,  we  conclude  that 
there is a material misstatement of this other information, 
we are required to report that fact. 

We have nothing to report in this regard. 

OPINIONS  ON  OTHER  MATTERS  PRESCRIBED  BY  THE 
COMPANIES ACT 2006

In our opinion, based on the work undertaken in the course 
of the audit: 

• 

• 

the  information  given  in  the  strategic  report  and  the 
directors’  report  for  the  financial  year  for  which  the 
financial statements are prepared is consistent with the 
financial statements; and 

the  strategic  report  and  the  directors’  report  have 
been  prepared  in  accordance  with  applicable  legal 
requirements. 

MATTERS ON WHICH WE ARE REQUIRED TO REPORT BY 
EXCEPTION 

In  the  light  of  the  knowledge  and  understanding  of  the 
Group  and  the  Company  and  their  environment  obtained 
in  the  course  of  the  audit,  we  have  not  identified  material 
misstatements in the strategic report or the directors’ report. 

We have nothing to report in respect of the following matters 
in relation to which the Companies Act 2006 requires us to 
report to you if, in our opinion: 

• 

• 

• 

adequate accounting records have not been kept by the 
Company,  or  returns  adequate  for  our  audit  have  not 
been received from branches not visited by us; or 

the Company financial statements are not in agreement 
with the accounting records and returns; or 

certain disclosures of directors’ remuneration specified 
by law are not made; or 

•  we  have  not 

received  all 

the 

information  and 

explanations we require for our audit. 

RESPONSIBILITIES OF DIRECTORS 

As  explained  more  fully  in  the  Statement  of  Directors’ 
responsibilities,  the  directors  are  responsible  for  the 
preparation of the Group and Company financial statements 
and  for  being  satisfied  that  they  give  a  true  and  fair  view, 
and for  such  internal  control as the  directors  determine is 
necessary to enable the preparation of financial statements 
that  are  free  from  material  misstatement,  whether  due  to 
fraud or error. 

In preparing the Group and Company financial statements, 
the  directors  are  responsible  for  assessing  the  Group  and 
the  Company’s  ability  to  continue  as  a  going  concern, 
disclosing, as applicable, matters related to going concern 
and using the going concern basis of accounting unless the 
directors either intend to liquidate the Group or the Company 
or to cease operations, or have no realistic alternative but to 
do so. 

AUDITOR’S  RESPONSIBILITIES  FOR  THE  AUDIT  OF  THE 
FINANCIAL STATEMENTS 

Our  objectives  are  to  obtain  reasonable  assurance  about 
whether the financial statements as a whole are free from 
material  misstatement,  whether  due  to  fraud  or  error, 
and  to  issue  an  auditor’s  report  that  includes  our  opinion. 
Reasonable  assurance  is  a  high  level  of  assurance  but  is 
not  a  guarantee  that  an  audit  conducted  in  accordance 
with ISAs (UK) will always detect a material misstatement 
when  it  exists.  Misstatements  can  arise  from  fraud  or 
error  and  are  considered  material  if,  individually  or  in  the 
aggregate, they could reasonably be expected to influence 
the economic decisions of users taken on the basis of these 
financial statements. 

including  fraud,  are 
laws  and 

Irregularities, 
instances  of  non-
regulations.  We  design 
compliance  with 
procedures in line with our responsibilities, outlined above, 
to detect material misstatements in respect of irregularities, 
including  fraud.  The  extent  to  which  our  procedures  are 
capable of detecting irregularities, including fraud is detailed 
below:

•  We  obtained  an  understanding  of  the  Group  and 
Company  and  the  sector  in  which  they  operate  to 
identify  laws  and  regulations  that  could  reasonably 
be  expected  to  have  a  direct  effect  on  the  financial 
statements.  We  obtained  our  understanding  in  this 
regard  through  discussions  with  management,  review 
of  accident  logbooks,  and  application  of  cumulative 
audit knowledge and experience of the quarrying sector.

•  We  determined  the  principal  laws  and  regulations 
relevant to the Group and Company in this regard to be 
those arising from the:  

•  Companies Act 2006;
•  UK-adopted international accounting standards;
•  Quoted Companies Alliance Code;

also  greater  regarding  irregularities  occurring  due  to  fraud 
rather than error, as fraud involves intentional concealment,

of  the  financial  statements  is  located  on  the  Financial 
Reporting Council’s website at:

www.frc.org.uk/auditorsresponsibilities

•  We designed our audit procedures to ensure the audit 
team considered whether there were any indications of 
non-compliance by the Group and Company with those 
laws  and  regulations.  These  procedures  included,  but 
were not limited to:

•  Making enquiries of management; 
•  Reviewing board meeting minutes;
•  Reviewing 

Regulatory 

News 

Service 

announcements;

• 

Ensuring  adherence  to  the  terms  within  the 
exploration  permits, 
including  environmental 
conditions; and

•  Reviewing  legal  and  regulatory  correspondence 
and reviewing legal and professional fees. 

•  We also identified the risks of material misstatement of 
the  financial  statements  due  to  fraud.  We  considered, 
in addition to the non-rebuttable presumption of a risk 
of fraud arising from management override of controls, 
that the potential for management bias was identified 
in relation to the valuation of goodwill and investments 
(noted in the Key audit matters section of our report) as 
well as the valuation of the defined benefit obligations, 
including  the  key  actuarial  assumptions  applied.  We 
addressed  this  by  challenging  the  assumptions  and 
judgements  made  by  management  when  auditing 
that  significant  accounting  estimate  and  ensuring 
that  there  were  adequate  disclosures  included  in  the 
respective notes including the disclosures within critical 
accounting estimates.

This description forms part of our auditor’s report. 

USE OF OUR REPORT

This  report  is  made  solely  to  the  Company’s  members, 
as a body, in accordance with Chapter 3 of Part 16 of the 
Companies Act 2006. Our audit work has been undertaken 
so  that  we  might  state  to  the  Company’s  members  those 
matters we are required to state to them in an auditor’s report 
and for no other purpose. To the fullest extent permitted by 
law, we do not accept or assume responsibility to anyone, 
other than the Company and the Company's members as a 
body, for our audit work, for this report, or for the opinions 
we have formed.

•  We  addressed 

the 

fraud  arising 

from 
risk  of 
management override of controls by performing audit 
procedures  which  included,  but  were  not  limited  to: 
testing of journals; reviewing accounting estimates for 
evidence of bias; and evaluating the business rationale 
of  any  significant  transactions  that  are  unusual  or 
outside the normal course of business.

•  As part of the Group audit, we have communicated with 
component  auditors  the  fraud  risks  associated  with 
the  Group  and  the  need  for  the  component  auditors 
to address  the risk  of fraud in  their testing. To ensure 
that  this  has  been  completed,  we  have  reviewed 
component  auditor  working  papers  in  this  area  and 
obtained responses to our Group instructions from the 
component auditors.

Because  of  the  inherent  limitations  of  an  audit,  there  is 
a  risk  that  we  will  not  detect  all  irregularities,  including 
those  leading  to  a  material  misstatement  in  the  financial 
statements  or  non-compliance  with  regulation.  This  risk 
increases the more that compliance with a law or regulation 
is  removed  from  the  events  and  transactions  reflected 
in  the  financial  statements,  as  we  will  be  less  likely  to 
become aware of instances of non-compliance. The risk is

Notes to the financial statements

1. GENERAL INFORMATION

The  principal  activity  of  SigmaRoc  is  to  make  investments 
and/or acquire projects in the quarried materials sector, and 
the principal activity of the Group is the production of high-
quality aggregates and supply of value-added industrial and 
construction materials. The Company’s shares are admitted 
to trading on AIM and it is incorporated and domiciled in the 
United Kingdom. 

The  address  of  its  registered  office  is  6  Heddon  Street, 
London, W1B 4BT.

2.  ACCOUNTING POLICIES

The principal accounting policies applied in the preparation 
of these Financial Statements are set out below (‘Accounting 
Policies’ or ‘Policies’). These Policies have been consistently 
applied to all the periods presented, unless otherwise stated.

2.1. Basis of Preparing the Financial Statements

The  Group  and  Company  Financial  Statements  have  been 
prepared 
in  accordance  with  UK-adopted  International 
Accounting  Standards  and  with  the  requirements  of  the 
Companies Act 2006. The consolidated financial statements 
have been prepared under the historical cost convention, as 
modified by the revaluation of property, plant and equipment 
and intangible assets; financial assets and financial liabilities 
at fair value through profit or loss; derivatives held for hedge 
accounting classified as financial assets at fair value through 
other comprehensive income,  and defined benefit pension 
plans for which the plan assets are measured at fair value.

The  Financial  Statements  are  presented  in  UK  Pounds 
Sterling rounded to the nearest thousand.

The preparation of Financial Statements in conformity with UK 
IASs requires the use of certain critical accounting estimates. 
It also requires management to exercise its judgement in the 
process  of  applying  the  Group’s  Accounting  Policies.  The 
areas involving a higher degree of judgement or complexity, or 
areas where assumptions and estimates are significant to the 
Financial Information are disclosed in Note 4.

a) Changes in Accounting Policy

i) New standards and amendments adopted by the Group

The  IASB  issued  various  amendments  and  revisions  to 
UK  IAS  and  IFRSIC  interpretations  which  include  IFRS  3 
-  Reference  to  Conceptual  Framework,  IAS  37  –  Onerous 
Contracts,  IAS  16  –  Proceeds  before  intended  use,  IAS  8 
–  Accounting  estimates,  IAS  12  -  Deferred Tax  and  Annual 
Improvements – 2018 – 2020 Cycle. The amendments and 
revisions were applicable for the period ended 31 December 
2023  but  did  not  result  in  any  material  changes  to  the 
financial statements of the Group or Company.

ii) New standards, amendments and interpretations in issue 
but not yet effective or not early adopted

Standards, amendments and interpretations that are not yet 
effective and have not been early adopted are as follows:

The  Group  and  Company  are  evaluating  the  impact  of  the 
new and amended standards above which are not expected 
to have a material impact on the Group or Company’s results 
or shareholders’ funds.

2.2. Basis of Consolidation

a) Subsidiaries

The  Consolidated  Financial  Statements  consolidate  the 
Financial Statements of the Company and the accounts of 
all of its subsidiary undertakings for all periods presented.

Subsidiaries  are  entities  over  which  the  Group  has  control. 
The Group controls an entity when the Group is exposed to, 
or  has  rights  to,  variable  returns  from  its  involvement  with 
the entity and has the ability to affect those returns through 
its power over the entity. Subsidiaries are fully consolidated 
from the date on which control is transferred to the Group. 
On  consolidation  all  inter-company  transactions,  balances 
and  unrealised  gains  and  losses  on  transactions  between 
group  companies  are  eliminated.  They  are  deconsolidated 
from the date that control ceases.

The  Group  applies  the  acquisition  method  of  accounting 
to  account  for  business  combinations. The  Consideration 
transferred  for  the  acquisition  of  a  subsidiary  is  the  fair 
values  of  the  assets  transferred,  the  liabilities  incurred  to 
the former owners of the acquiree and the equity interests 
issued by the Group. The consideration transferred includes 
the  fair  value  of  any  asset  or  liability  resulting  from  a 
contingent  consideration  arrangement.  Identifiable  assets 
acquired  and  liabilities  and  contingent  liabilities  assumed 
in a business combination are measured initially at their fair 
values at the acquisition date.

Acquisition-related  costs  are  expensed  as  incurred  unless 
they result from the issuance of shares, in which case they 
are offset against the premium on those shares within equity.

Any  contingent  consideration  to  be  transferred  by  the 
Group  is  recognised  at  fair  value  at  the  acquisition  date. 
Subsequent  changes  to  the  fair  value  of  the  contingent 
consideration  that  is  deemed  to  be  an  asset  or  liability  is 
recognised in accordance with IAS 37 either in profit or loss 
or as a change to other comprehensive income. Contingent 
consideration that is classified as equity is not re-measured, 
and its subsequent settlement is accounted for within equity.

Investments  in  subsidiaries  are  accounted  for  at  cost  less 
impairment. 

Where considered appropriate, adjustments are made to the 
financial information of subsidiaries to bring the accounting 
policies  used  into  line  with  those  used  by  other  members 
of  the  Group.  All  intercompany  transactions  and  balances 
between Group enterprises are eliminated on consolidation.

CDH,  B-Mix,  Stone,  Goijens,  Betons  and  GduH  use  Belgian 
GAAP rules to prepare and report their financial statements. 
The  Group  reports  using  UK  IAS  standards  and  in  order  to 
comply with the Group’s reporting standards, management 
of  CDH,  GduH,  B-Mix  and  Goijens  processed  several 
adjustments to ensure the financial information included at 
a Group level complies with UK IAS. CDH, GduH, B-Mix  and 

FINANCIAL REPORTSIGMAROC ANNUAL REPORT 2023203

Goijens  will  continue  to  prepare  their  company  financial 
statements in line with the Belgian GAAP rules. 

Nordkalk entities use local GAAP rules to prepare and report 
their financial statements. The Group reports using UK IAS 
standards and in order to comply with the Group’s reporting 
standards,  management  of  Nordkalk  processed  several 
adjustments to ensure the financial information included at 
a Group level complies with UK IAS. Nordkalk will continue 
to  prepare  their  company  financial  statements  in  line  with 
the local GAAP rules. 

a strong focus on operational gearing, it can remain flexible 
during  economically  disruptive  events  which  can  have  a 
negative effect on cash flow.

At 31 December 2023, the Group had cash of £55.9 million 
(2022: £68.6 million) and undrawn banking facilities under 
the legacy debt of £173 million (2022: £173 million), and at 
the  date  of  this  report  has  similar  levels  of  liquidity  which 
is  expected  to  provide  sufficient  funds  for  the  Group  to 
discharge its liabilities as and when they fall due and ensure 
covenants are met.

The  Group  recognises  any  non-controlling 
interest  at 
the  non-controlling  interest’s  proportionate  share  of  the 
recognised amounts of acquiree’s identifiable net assets.

Based  on  the  above,  the  directors  believe  that  it  remains 
appropriate to prepare the financial statements on a Going 
Concern basis.

b) Associates

2.4. Segment Reporting

Associates are entities over which the Group has significant 
influence  but  not  control  over  the  financial  and  operating 
policies. Investments in associates are accounted for using 
the equity method of accounting and are initially recognised 
at cost. The Group’s share of its associates’ post-acquisition 
profits or losses is recognised in profit or loss, and its share 
of  post-acquisition  movements  in  reserves  is  recognised 
in  other  comprehensive  income.  The  cumulative  post-
acquisition  movements  are  adjusted  against  the  carrying 
amount of the investment.

Accounting  policies  of  equity–accounted  investees  have 
been changed where necessary to ensure consistency with 
the policies adopted by the Group.

c) Joint Arrangement

A  joint  arrangement  is  an  arrangement  in  which  two  or 
more  parties  have  joint  control.  A  joint  venture  is  a  joint 
arrangement  in  which  the  parties  that  share  joint  control 
have  rights  to  the  net  assets  of  the  arrangement.  Joint 
arrangements are accounted for using the equity method of 
accounting and are initially recognised at cost. The Group’s 
share of its associates’ post-acquisition profits or losses is 
recognised in profit or loss.  

d) Employee Benefit Trust

Where considered appropriate, adjustments are made to the 
financial information of subsidiaries to bring the accounting 
policies  used  into  line  with  those  used  by  other  members 
of  the  Group.  All  intercompany  transactions  and  balances 
between Group enterprises are eliminated on consolidation.

The  Employee  Benefit  Trust  is  considered  to  be  a  special 
purpose  entity  in  which  the  substance  of  the  relationship 
is that of control by the Group in order that the Group may 
benefit  from  its  control.  The  assets  held  by  the  trust  are 
consolidated into the Group.

2.3. Going Concern

The  Financial  Statements  have  been  prepared  on  a  going 
concern basis which the directors consider to be appropriate 
for the following reasons.

The  Group  meets  its  day-to-day  working  capital  and  other 
funding  requirements  through  operating  cash  generation 
and its Debt Facilities. The Debt Facilities comprise of a €600 
million committed term facility, €150 million revolving credit 
facility  and  a  further  €100  million  uncommitted  accordion 
which matures on 21 November 2028. The Group has met 
all covenants on its Debt Facilities. 

The Group has prepared cash flow forecasts for a period of 
more than 12 months which anticipate a continuous upward 
trend of profitability and cash generation. As the Group has 

Operating  segments  are  reported  in  a  manner  consistent 
with  the  internal  reporting  provided  to  the  chief  operating 
decision-maker.  The  chief  operating  decision-maker,  who 
is  responsible  for  allocating  resources  and  assessing 
performance of the operating segments, has been identified 
as the Board of Directors that makes strategic decisions.

2.5. Foreign Currencies

e) Functional and Presentation Currency

Items  included  in  the  Financial  Statements  are  measured 
using  the  currency  of  the  primary  economic  environment 
in which the entity operates (the ‘functional currency’). The 
Financial  Statements  are  presented  in  Pounds  Sterling, 
rounded  to  the  nearest  £000’s,  which  is  the  Company’s 
functional currency.

f) Transactions and Balances

into  the 
Foreign  currency  transactions  are  translated 
functional  currency  using  the  exchange  rates  prevailing 
at  the  dates  of  the  transactions  or  valuation  where  such 
items are re-measured. Foreign exchange gains and losses 
resulting from the settlement of such transactions and from 
the  translation  at  year-end  exchange  rates  of  monetary 
assets and liabilities denominated in foreign currencies are 
recognised  in  the  Income  Statement.    Foreign  exchange 
gains  and  losses  that  relate  to  borrowings  and  cash  and 
cash  equivalents  are  presented  in  the  Income  Statement 
within ‘finance income or costs’. An exception to this is when 
the  borrowings  exchange  differences  arise  on  monetary 
items that form part of the reporting entity’s net investment 
in  the  consolidated  financial 
in  a  foreign  operation, 
statements the exchange gain or loss will be shown in other 
comprehensive  income.  All  other  foreign  exchange  gains 
and  losses  are  presented  in  the  Income  Statement  within 
‘Other net gains/(losses)’.

Translation  differences  on  non-monetary  financial  assets 
and  liabilities  such  as  equities  held  at  fair  value  through 
profit  or  loss  are  recognised  in  profit  or  loss  as  part  of 
the  fair  value  gain  or  loss. Translation  differences  on  non-
monetary  financial assets  measured at fair  value,  such  as 
equities classified as available for sale, are included in other 
comprehensive income.

g) Group companies

The  results  and  financial  position  of  all  the  Group  entities 
(none  of  which  has  the  currency  of  a  hyperinflationary 
economy) that have a functional currency different from the 
presentation  currency  are  translated  into  the  presentation 
currency as follows:
• 

assets and liabilities for each period end date presented 
are translated at the period-end closing rate;

Notes to the financial statements

• 

• 

income  and  expenses  for  each  Income  Statement 
are  translated  at  average  exchange  rates  (unless 
this  average  is  not  a  reasonable  approximation  of 
the  cumulative  effect  of  the  rates  prevailing  on  the 
transaction dates, in which case income and expenses 
are translated at the dates of the transactions); and

all  resulting  exchange  differences  are  recognised  in 
other comprehensive income.

Goodwill and fair value adjustments arising on the acquisition 
of a foreign entity are treated as assets and liabilities of the 
foreign entity and translated at the closing rate.  Exchange 
differences  arising  are recognised in  other  comprehensive 
income.  On  consolidation,  exchange  differences  arising 
from the translation of the net investment in foreign entities, 
and of monetary items receivable from foreign subsidiaries 
for  which  settlement  is  neither  planned  nor  likely  to  occur 
in the foreseeable future, are taken to other comprehensive 
income.  When  a  foreign  operation  is  sold,  such  exchange 
differences are recognised in the Income Statement as part 
of the gain or loss on sale.

2.6. Intangible Assets

The  Group  measures  goodwill  as  the  fair  value  of  the 
purchase consideration transferred including the recognised 
amount  of  any  non-controlling  interest  in  the  acquiree, 
less  the  fair  value  of  the  identifiable  assets  acquired  and 
liabilities assumed, all measured as of the acquisition date. 
If  the  total  of  consideration  transferred,  non-controlling 
interest  recognised  and  previously  held  interest  measured 
at fair value is less than the fair value of the net assets of the 
subsidiary acquired, in the case of a bargain purchase, the 
difference is recognised directly in the Income Statement.

As  reported  within  the  CEO’s  strategic  report,  a  PPA  was 
carried out to assess the fair value of the assets acquired 
in JQG and Goijens as at the completion date. As a result 
of  this  exercise,  goodwill  in  JQG  decreased  from  £40.2 
million  to  £7.1  million  with  the  corresponding  movement 
being land and minerals and other intangibles. Goodwill in 
Goijens  decreased  from  £5.1  million  to  £1.6  million  with 
the corresponding movement being land and buildings and 
customer  relationships.  The  current  accounting  policies 
regarding the subsequent treatment of intangible assets will 
apply to fair value uplift attributable to the PPA.

Amortisation  is  provided  on  intangible  assets  to  write  off 
the cost less estimated residual value of each asset over its 
expected useful economic life on a straight-line basis at the 
following annual rates:

Goodwill

Customer relations

Intellectual property

Research and Development

Branding

Other intangibles

0%

7% - 12.5%

10% – 12%

10% – 20%

5% - 10%

10% - 20%

For the purpose of impairment testing, goodwill acquired 
in  a  business  combination  is  allocated  to  each  of  the 
entities, or group of entities, that are expected to benefit 
from  the  synergies  of  the  combination.  Goodwill  is 
monitored at a Group level.

Goodwill is not amortised however impairment reviews are 
undertaken annually, or more frequently if events or changes 
in circumstances indicate a potential impairment. When the 
carrying value of goodwill exceeds the recoverable amount, 
(the  higher  of  value  in  use  and  fair  value  less  costs)  an 
impairment is recognised immediately as an expense and is 
not subsequently reversed.

Other intangibles consist of capitalised development costs for 
assets produced that assist in the operations of the Group and 
earn  revenue.  Impairment  reviews  are  performed  annually. 
Where  the  benefit  of  the  intangible  ceases  or  has  been 
superseded, these are written off to the Income Statement.

2.7. Property, Plant and Equipment

Property, plant and equipment is stated at cost, plus any PPA 
uplift,  less  accumulated  depreciation  and  any  accumulated 
impairment  losses.  Subsequent  costs  are  included  in  the 
asset’s carrying amount or recognised as a separate asset, 
as appropriate, only when it is probable that future economic 
benefits associated with the item will flow to the Group and 
the cost of the item can be measured reliably. The carrying 
amount of the replaced part is derecognised. All other repairs 
and  maintenance  are  charged  to  the  Income  Statement 
during the financial period in which they are incurred.

Depreciation is provided on all property, plant and equipment 
to write off the cost less estimated residual value of each 
asset over its expected useful economic life on a straight-
line basis at the following annual rates:

Office equipment

Land and buildings

Plant and machinery

12.5% – 50%

0% – 10%

4% – 33%

Furniture and vehicles

7.5% – 33.3%

Construction in progress

0%

The assets’ residual values and useful lives are reviewed, and 
adjusted if appropriate, at the end of each reporting period.

An asset’s carrying amount is written down immediately to its 
recoverable amount if the asset’s carrying amount is greater 
than its estimated recoverable amount.

Gains and losses on disposal are determined by comparing 
the  proceeds  with  the  carrying  amount  and  are  recognised 
within ‘Other net gains/(losses)’ in the Income Statement.

2.8. Land, Mineral Rights and Restoration Costs

Land,  quarry  development  costs,  which  include  directly 
attributable  construction  overheads  and  mineral  rights 
are  recorded  at  cost  plus  any  PPA  uplift.    Land  and  quarry 
development  are  depreciated  and  amortised,  respectively, 
using  the  units  of  production  method,  based  on  estimated 
recoverable tonnage. 

Where  the  Group  has  a  legal  or  constructive  obligation  for 
restoration of a site the costs of restoring this site is provided 
for.    The  initial  cost  of  creating  this  provision  is  capitalised 
within property, plant and equipment and depreciated over the 
life of the site.   The provisions are discounted to their present 
value  at  a  rate  which  reflects  the  time  value  of  money  and 
risks specific to the liability.   Changes in the measurement 
of a previously capitalized provision are accordingly added or 
deducted from the value of the asset.  

FINANCIAL REPORTSIGMAROC ANNUAL REPORT 2023The depletion of mineral rights and depreciation of restoration 
costs are expensed by reference to the quarry activity during 
the period and remaining estimated amounts of mineral to be 
recovered over the expected life of the operation.

The process of removing overburden and other mine waste 
materials  to  access  mineral  deposits  is  referred  to  as 
stripping.

There are two types of stripping activity:
•  Development stripping is the initial overburden removal 
during  the  development  phase  to  obtain  access  to  a 
mineral deposit that will be commercially produced.
•  Production  stripping  relates  to  overburden  removal 
during  the  normal  course  of  production  activities  and 
commences after the first saleable minerals have been 
extracted from the component.

Development stripping costs are capitalised as a development 
stripping asset when:
• 

It is probable that future economic benefits associated 
with the asset will flow to the entity; and

• 

The costs can be measured reliably.

Production  stripping  can  give  rise  to  two  benefits,  the 
extraction of ore in the current period and improved access 
to  the ore body component in future periods. To the extent 
that  the  benefit  is  the  extraction  of  ore,  stripping  costs  are 
recognised  as  an  inventory  cost.  To  the  extent  that  the 
benefit is improved access to future ore, stripping costs are 
recognised  as  a  production  stripping  asset  if  the  following 
criteria are met:

• 

• 

• 

 It is probable that the future economic benefit (improved 
access to ore) will flow to the entity;

The component of the ore body for which access has 
been improved can be identified; and

The  costs  relating  to  the  stripping  activity  can  be 
measured reliably.

The  development  and  production  stripping  assets  are 
depreciated in accordance with units of production based on 
the proven and probable reserves of the relevant components. 
Stripping  assets  are  classified  as  other  minerals  assets  in 
property, plant and equipment.

2.9. Financial Assets

Classification

The Group’s financial assets consist of loans and receivables. 
The  classification  depends  on  the  purpose  for  which  the 
financial assets were acquired. Management determines the 
classification of its financial assets at initial recognition.

(i) Financial Assets at Fair Value through Profit or Loss

Financial assets at fair value through profit or loss are financial 
assets held for trading.  A financial asset is classified in this 
category  if  acquired  principally  for  the  purpose  of  selling  in 
the short term.  Derivatives are also categorised as held for 
trading unless they are designated as hedges.

Assets  in  this  category  are  classified  as  current  assets  if 
expected to be settled within 12 months; otherwise, they are 
classified as non-current.  

(ii)  Financial  Assets  at  Fair  Value 

through  other 

comprehensive income

A financial asset is classified and subsequently measured at 
fair value through other comprehensive income if it meets the 

205

SPPI criterion and is managed in a business model in which 
assets are held both for sale and to collect contractual cash 
flows, or if an investment in an equity instrument is elected 
to  be  measured  at  fair  value  through  other  comprehensive 
income.  Derivatives  eligible  for  hedge  accounting  are 
classified  as  financial  assets  at  fair  value  through  other 
comprehensive income.

(iii) Loans and Receivables

Loans  and  receivables  are  non-derivative  financial  assets 
with fixed or determinable payments that are not quoted in 
an active market.  They are included in current assets, except 
for maturities greater than 12 months after the balance sheet 
date. These are classified as non-current assets. The Group’s 
loans and receivables comprise trade and other receivables 
and cash and cash equivalents at the year-end.

Recognition and Measurement

Regular  purchases  and  sales  of  financial  assets  are 
recognised on the trade date – the date on which the Group 
commits to purchasing or selling the asset.  Financial assets 
carried at fair value through profit or loss is initially recognised 
at  fair  value,  and  transaction  costs  are  expensed  in  the 
Income Statement.  Financial assets are derecognised when 
the rights to receive cash flows from the assets have expired 
or  have  been  transferred,  and  the  Group  has  transferred 
substantially all of the risks and rewards of ownership. 

Loans and receivables are subsequently carried at amortised 
cost using the effective interest method.

Gains  or  losses  arising  from  changes  in  the  fair  value  of 
financial  assets  at  fair  value  through  profit  or  loss  are 
presented  in  the  Income  Statement  within  “Other  (Losses)/
Gains” in the period in which they arise.

Derivative Financial Instruments

The  majority  of  the  Group’s  strategic  hedging  programme 
is delivered using executory contracts to forward purchase 
exchange contracts or commodities for our own use. 

The Group uses financial instruments to manage financial 
risks  associated  with  the  Group’s  underlying  business 
activities  and  the  financing  of  those  activities.  The  Group 
does  not  undertake  any  trading  in  financial  instruments. 
Derivatives  are 
initially  recognised  at  fair  value  and 
subsequently remeasured in future periods at fair value. The 
gain or loss on remeasurement is recognised immediately 
in  profit  or  loss,  unless  a  derivative  financial  instrument  is 
designated as a hedge of the variability in cash flows of a 
recognised  asset  or  liability.    In  this  instance  the  effective 
part  of  any  gain  or  loss  is  recognised  in  the  consolidated 
statement of comprehensive income and in the revaluation 
reserve.

the

Amounts 
subsequently  reclassified  to  the  consolidated 
income 
statement when the expense for the hedged transaction is 
actually  recognised.  To  qualify  for  hedge  accounting,  the 
hedging  relationship  must  meet  several  conditions  with 
respect to documentation, probability of occurrence, hedge 
effectiveness and reliability of measurement.

At inception of the hedge relationship, the Group documents 
the  economic  relationship  between  hedging  instruments 
and  hedged  items,  including  whether  changes  in  the  cash 
flows  of  the  hedging  instruments  are  expected  to  offset 
changes  in  the  cash  flows  of  hedged  items.  The  Group 
documents its risk management objective and strategy for 
undertaking its hedge transactions.

Notes to the financial statements

The  fair  values  of  various  derivative  instruments  used  for 
hedging purposes are disclosed in Note 33.  Movements on 
the  revaluation  reserve  in  shareholders’  equity  are  shown 
in  Note  30.    The  full  fair  value  of  a  hedging  derivative  is 
classified as a non-current asset or liability if the remaining 
maturity of the hedged item is more than 12 months, and 
as a current asset or liability if the remaining maturity of the 
hedged item is less than 12 months.  Trading derivatives are 
classified as a current asset or liability.

Impairment of Financial Assets

The  Group  assesses  at  the  end  of  each  reporting  period 
whether  there  is  the  need  to  recognise  loss  allowances 
for  expected  credit  losses  on  financial  assets.  These  are 
measured  at  amortised  cost.  The  Group  measures  loss 
allowances  at  an  amount  equal  to  lifetime  expected  credit 
losses,  except  for  bank  balances  for  which  credit  risk  has 
not increased significantly since initial recognition, which are 
measured as 12-month expected credit loss. 

The loss is measured as the difference between the asset’s 
carrying  amount  and  the  present  value  of  estimated  future 
cash flows (excluding future credit losses that have not been 
incurred), discounted at the financial asset’s original effective 
interest rate.

If, in a subsequent period, the amount of the impairment loss 
decreases and the decrease can be related objectively to an 
event occurring after the impairment was recognised (such 
as an improvement in the debtor’s credit rating), the reversal 
of the previously recognised impairment loss is recognised in 
the Income Statement.

2.10. Inventories

Inventories are initially recognised at cost, and subsequently 
at  the  lower  of  cost  and  net  realisable  value,  which  is  the 
estimated  selling  price  in  the  ordinary  course  of  business, 
less  applicable  variable  selling  expenses.  Cost  comprises 
all costs of purchase, costs of conversion and other costs 
incurred in bringing the inventories to their present location 
and condition. In the case of manufactured inventories and 
work  in  progress,  cost  includes  an  appropriate  share  of 
overheads based on normal operating capacity.

Weighted  average  cost  is  used  to  determine  the  cost  of 
ordinarily interchangeable items.

2.11. Trade Receivables

Trade  receivables  are  recognised  initially  at  fair  value, 
and  subsequently  measured  at  amortised  cost  using  the 
effective  interest  method,  less  provision  for  impairment. 
Trade receivables are amounts due from third parties in the 
ordinary course of business. If collection is expected in one 
year or less, they are classified as current assets. If not, they 
are presented as non-current assets.

Trade receivables – factoring

The  carrying  amounts  of  the  trade  receivables  excludes 
receivables  which  are  subject  to  a  factoring  arrangement. 
Under  this  arrangement,  the  Group  has  transferred  the 
relevant  receivables  to  the  factor  in  exchange  for  cash 
without  recourse.  Therefore, 
it  doesn’t  recognise  the 
transferred assets in their entirety in its balance sheet.

The  value  of  factored  receivables  at  each  year  end  are  as 
follows:

31 December 
2023 
£’000

31 December 
2022 
£’000

Total factoring 

5,927

5,004

2.12. Cash and Cash Equivalents

Cash  and  cash  equivalents  comprise  cash  at  bank  and  in 
hand and are subject to an insignificant risk of changes in 
value.

2.13. Share Capital

Ordinary shares are classified as equity. Incremental costs 
directly  attributable  to  the  issue  of  new  shares  or  options 
are  shown  in  equity  as  a  deduction,  net  of  tax,  from  the 
proceeds.

2.14. Reserves

Share Premium – the reserve for shares issued above the 
nominal value. This also includes the cost of share issues 
that occurred during the year.

Retained Earnings – the retained earnings reserve includes 
all current and prior periods retained profit and losses.

Share Option Reserve – represents share options awarded 
by the Company.

Other Reserves comprise the following:

Capital  Redemption  Reserve  –  the  capital  redemption 
reserve  is  the  amount  equivalent  to  the  nominal  value  of 
shares redeemed by the Group.

Foreign  Currency  Translation  Reserve  -  represents  the 
translation differences arising from translating the financial 
statement items from functional currency to presentational 
currency.

Deferred  Shares  –  are  shares  that  effectively  do  not  have 
any rights or entitlements.

Capital  Reserve  –  represents  cash  that  can  be  used  for 
future expenses or to offset any capital losses. 

Revaluation Reserve – represents the changes of values in 
certain assets and includes derivative instruments used for 
cash-flow hedging

2.15. Trade Payables

Trade payables are obligations to pay for goods or services 
that have been acquired in the ordinary course of business 
from suppliers. Accounts payable are classified as current 
liabilities  if  payment  is  due  within  one  year  or  less.  If  not, 
they are presented as non-current liabilities. 

Trade  payables  are  recognised  initially  at  fair  value,  and 
subsequently  measured  at  amortised  cost  using  the 
effective interest method.

2.16. Provisions

The Group provides for the costs of restoring a site where a 
legal or constructive obligation exists. The estimated future 
costs for known restoration requirements are determined on 
a site-by-site basis and are calculated based on the present 
value of estimated future costs. 

FINANCIAL REPORTSIGMAROC ANNUAL REPORT 2023The amount recognised as a provision is the best estimate 
of the consideration required to settle the present obligation 
at  the  end  of  the  reporting  period,  taking  into  account  the 
risks  and  uncertainties  surrounding  the  obligation.  When 
a  provision  is  measured  using  the  cash  flows  estimated 
to  settle  the  present  obligation,  its  carrying  amount  is  the 
present value of those cash flows (where the effect of the 
time value of money is material). The increase in provisions 
due to the passage of time is included in the Consolidated 
Income Statement.

2.17. Borrowings

Bank and Other Borrowings

Interest-bearing  bank 
loans  and  overdrafts  and  other 
loans  are  recognised  initially  at  fair  value  less  attributable 
transaction  costs.  All  borrowings  are  subsequently  stated 
at  amortised  cost  with  the  difference  between  initial  net 
proceeds  and  redemption  value  recognised  in  the  Income 
Statement  over  the  period  to  redemption  on  an  effective 
interest basis.

2.18. Taxation

Tax  is  recognised  in  the  Income  Statement,  except  to 
the  extent  that  it  relates  to  items  recognised  in  other 
comprehensive income or directly in equity. In this case, the 
tax  is  also  recognised  in  other  comprehensive  income  or 
directly in equity, respectively. 

Deferred  tax  is  recognised  using  the  liability  method  in 
respect  of  temporary  differences  arising  from  differences 
between the carrying amount of assets and liabilities in the 
consolidated  financial  statements  and  the  corresponding 
tax  bases  used  in  the  computation  of  taxable  profit. 
However,  deferred  tax  liabilities  are  not  recognised  if  they 
arise  from  the  initial  recognition  of  goodwill;  deferred  tax 
is  not  accounted  for  if  it  arises  from  initial  recognition  of 
an  asset  or  liability  in  a  transaction  other  than  a  business 
combination  that  at  the  time  of  the  transaction  affects 
neither accounting nor taxable profit or loss. 

In  principle,  deferred  tax  liabilities  are  recognised  for  all 
taxable  temporary  differences  and  deferred  tax  assets 
(including  those  arising  from  investments  in  subsidiaries), 
are recognised to the extent that it is probable that taxable 
profits will be available against which deductible temporary 
differences can be utilised.

Deferred  income  tax  assets  are  recognised  on  deductible 
in 
temporary  differences  arising 
subsidiaries  only  to  the  extent  that  it  is  probable  the 
temporary  difference  will  reverse  in  the  future  and  there 
is  sufficient  taxable  profit  available  against  which  the 
temporary difference can be used.

investments 

from 

Deferred tax liabilities are recognised for taxable temporary 
differences  arising  on  investments  in  except  where  the 
Group  is  able  to  control  the  reversal  of  the  temporary 
difference and it is probable that the temporary difference 
will not reverse in the foreseeable future.

Deferred tax assets and liabilities are offset when there is a 
legally enforceable right to offset current tax assets against 
current tax liabilities and when the deferred tax assets and 
liabilities relate to income taxes levied by the same taxation 
authority  on  either  the  same  taxable  entity  or  different 
taxable  entities  where  there  is  an  intention  to  settle  the 
balances on a net basis.

Deferred  tax  is  calculated  at  the  tax  rates  (and  laws) 
that  have  been  enacted  or  substantively  enacted  by  the 

207

statement  of  financial  position  date  and  are  expected  to 
apply to the period when the deferred tax asset is realised, 
or the deferred tax liability is settled. 

Deferred tax assets and liabilities are not discounted.

2.19. Non-underlying Items

Non-underlying  items  are  a  non  UK  IAS  measure,  but  the 
Group  have  disclosed  these  separately  in  the  financial 
statements,  where  it  is  necessary  to  do  so  to  provide 
further  understanding  of  the  financial  performance  of  the 
Group.  They are items that are not expected to be recurring 
or  do  not  relate  to  the  ongoing  operations  of  the  Group’s 
business  and  non-cash  items  which  distort  the  underlying 
performance of the business.

2.20. Revenue Recognition

Group revenue arises from the sale of goods and contracting 
services.  Revenue  is  measured  at  the  fair  value  of  the 
consideration received or receivable and represents amounts 
receivable  for  goods  or  services  supplied  in  course  of 
ordinary business, stated net of discounts, returns and value 
added taxes. The Group recognises revenue in accordance 
with IFRS 15, identifying performance obligations within its 
contracts with customers, determining the transaction price 
applicable  to  each  of  these  performance  obligations  and 
selecting an appropriate method for the timing of revenue 
recognition,  reflecting  the  substance  of  the  performance 
obligation at either a point in time or over time.

Sale of goods

The majority of the Group’s revenue is derived from the sale 
of physical goods to customers. Depending on whether the 
goods  are  delivered  to  or  collected  by  the  customer,  the 
contract contains either one performance obligation which 
is  satisfied  at  the  point  of  collection,  or  two  performance 
obligations which are satisfied simultaneously at the point 
of delivery. The performance obligation of products sold are 
transferred according to the specific terms that have been 
formally agreed with the customer, generally upon delivery 
when the bill of lading is signed as evidence that they have 
accepted the product delivered to them.

The  transaction  price  for  this  revenue  is  the  amount  which 
can  be  invoiced  to  the  customer  once  the  performance 
obligations  are  fulfilled,  reduced  to  reflect  provisions 
recognised  for  returns,  trade  discounts  and  rebates.  The 
Group does not routinely offer discounts or volume rebates, 
but  where  it  does  the  variable  element  of  revenue  is  based 
on  the  most  likely  amount  of  consideration  that  the  Group 
believes it will receive. This value excludes items collected on 
behalf of third parties, such as sales and value added taxes.

For  all  sales  of  goods,  revenue  is  recognised  at  a  point  in 
time, being the point that the goods are transferred to the 
customer.

Contracting services

The  majority  of  contracting  services  revenue  arises  from 
contract  surfacing  work,  which  typically  comprises  short-
term contracts with a performance obligation to supply and 
lay product. Other contracting services revenue can contain 
more  than  one  performance  obligation  dependent  on  the 
nature of the contract.

The  transaction  price 
is  calculated  as  consideration 
specified  by  the  contract,  adjusted  to  reflect  provisions 
recognised for returns, remedial work arising in the normal 
course of business, trade discounts and rebates.

Notes to the financial statements

Where  the  contract  provides  for  elements  of  variable 
consideration,  these  values  are  included  in  the  calculation 
of  the  transaction  price  only  to  the  extent  that  it  is  ‘highly 
probable’  that  a  significant  reversal  in  the  amount  of 
cumulative  revenue  recognised  will  not  occur  when  the 
uncertainty  associated  with  the  variable  consideration  is 
resolved. Where the transaction price is allocated between 
multiple  performance  obligations  on  other  contracts,  this 
typically reflects the allocation of value to each performance 
obligation  agreed  with  the  end  customer,  unless  this  does 
not reflect the economic substance of the transaction.

Performance  obligations  for  contracting  services  are 
satisfied  over  time.  Revenue  is  therefore  recognised  over 
time  on  an  output  basis,  being  volume  of  product  laid  for 
contract surfacing. As the performance obligations relating 
to contracting revenues have an expected duration less than 
12 months, the Group has taken the practical expedient on 
the performance obligations disclosures. 

2.21. Finance Income

Interest  income  is  recognised  using  the  effective  interest 
method.

2.22. Employee Benefits - Defined contribution plans

The  Group  maintains  defined  contribution  plans  for  which 
the  Group  pays  fixed  contributions  to  publicly  or  privately 
administered  pension  insurance  plans  on  a  mandatory, 
contractual  or  voluntary  basis  and  will  have  no  legal 
or  constructive  obligation  to  pay  further  amounts.  The 
Group’s  contributions  to  defined  contribution  plans  are 
charged to the Income Statement in the period to which the 
contributions relate.

2.23. Employee Benefits - Defined benefit plans

The Group’s net obligation in respect of defined benefit plans 
is  calculated  separately  for  each  plan  by  estimating  the 
amount of the future benefit that employees have earned in 
the current and prior periods, discounting the amount and 
deducting the fair value of any plan assets. 

Defined  benefit  obligations  are  calculated  annually  by  a 
qualified  actuary  using  the  projected  unit  credit  method. 
When  the  calculation  results  in  a  potential  asset  for  the 
Group, the recognised asset is limited to the present value 
of  economic  benefits  available  in  the  form  of  any  future 
refunds from the plan or reductions in future contributions 
to  the  plan.  To  calculate  the  present  value  of  economic 
benefits, consideration is given to any applicable minimum 
funding requirements. 

Remeasurements  of  the  net  defined  benefit  liability,  which 
comprise  actuarial  gains  and  losses,  the  return  on  plan 
assets (excluding interest) and the effect of the asset ceiling 
(if  any,  excluding  interest),  are  recognised  immediately  in 
other  comprehensive  income.  The  Group  determines  the 
net  interest  expense  (income)  for  the  net  defined  benefit 
liability  (asset)  for  the  period  by  applying  the  discount 
rate  used  to  measure  the  defined  benefit  obligation  at  the 
beginning  of  the  annual  period  to  the  then-net  defined 
benefit liability (asset), taking into account any changes in 
the net defined benefit liability (asset) during the period as 
a result of contributions and benefit payments. Net interest 
expense relating to defined benefit plans are recognised in 
profit or loss in net financial items. 

When the benefits of a plan are changed or when a plan is 

curtailed, the resulting change in benefit that relates to past 
service or the gain or loss on the curtailment is recognised 
immediately  in  the  profit  or  loss.  The  Group  recognises 
gains and losses on the settlement of a defined benefit plan 
when the settlement occurs. 

2.24. Share Based Payments

The  Group  operates  a  number  of  equity-settled,  share-
based  schemes,  under  which  the  entity  receives  services 
from  employees  or  third-party  suppliers  as  consideration 
for equity instruments (options and warrants) of the Group. 
The fair value of the third-party suppliers’ services received 
in exchange for the grant of the options is recognised as an 
expense in the Consolidated Income Statement or charged 
to equity depending on the nature of the service provided. 
The  value  of  the  employee  services  received  is  expensed 
in  the  Income  Statement  and  its  value  is  determined  by 
reference to the fair value of the options granted:

• 
• 

• 

including any market performance conditions;

excluding  the  impact  of  any  service  and  non-market 
performance 
example, 
profitability  or  sales  growth  targets,  or  remaining  an 
employee of the entity over a specified time period); and

conditions 

vesting 

(for 

including the impact of any non-vesting conditions (for 
example, the requirement for employees to save).

Non-market vesting conditions are included in assumptions 
about  the  number  of  options  that  are  expected  to  vest. 
The total expense or charge is recognised over the vesting 
period,  which  is  the  period  over  which  all  of  the  specified 
vesting  conditions  are  to  be  satisfied.  At  the  end  of  each 
reporting  period,  the  entity  revises  its  estimates  of  the 
number of options that are expected to vest based on the 
non-market  vesting  conditions.  It  recognises  the  impact 
of  the  revision  to  original  estimates,  if  any,  in  the  Income 
Statement  or  equity  as  appropriate,  with  a  corresponding 
adjustment to a separate reserve in equity.

When  the  options  are  exercised,  the  Company  issues  new 
shares. The proceeds received, net of any directly attributable 
transaction  costs,  are  credited  to  share  capital  (nominal 
value) and share premium when the options are exercised.

2.25. Discontinued Operations

A  discontinued  operation  is  a  component  of  the  Group’s 
business,  the  operations  and  cash  flows  of  which  can  be 
clearly distinguished from the rest of the Group and which:

• 

• 

• 

represents  a  separate  major 
geographic area of operations;

line  of  business  or 

is  part  of  a  single  co-ordinated  plan  to  dispose  of  a 
separate major line of business or geographic area of 
operations; or

is  a  subsidiary  acquired  exclusively  with  a  view  to  
re-sale.

Classification  as  a  discontinued  operation  occurs  at  the 
earlier of disposal or when the operation meets the criteria 
to be classified as held-for-sale. The Group operates several 
business  units  which  are  constantly  reviewed  to  ensure 
profitability. During 2019 it was determined that the flagging 
&  paving  division  at  CCP’s  Bury  site  was  loss  making  and 
therefore it was decided that the operations at this site be 
discontinued. 

FINANCIAL REPORTSIGMAROC ANNUAL REPORT 20232.26. Leases

The  Group  leases  certain  plant  and  equipment.  Leases  of 
plant and equipment where the Group has substantially all 
the risks and rewards of ownership are classified as Right-
of-use assets and lease liability under IFRS 16.  

Right-of-use  assets  are  measured  at  cost,  comprising 
the  initial  amount  of  the  lease  liability  adjusted  for  any 
lease  prepayments,  plus  initial  direct  costs,  less  any  lease 
incentives  received.  Right-of-use  assets  are  depreciated 
using  the  straight-line  method  from  the  start  of  the  lease 
to the earlier of the end of the useful life of the right-of-use 
asset or the end of the lease term. 

Each  lease  payment  is  allocated  between  the  liability  and 
finance  charges. The  corresponding  rental  obligations,  net 
of finance charges, are included in long-term and short-term 
borrowings and are measured at the present value of future 
lease  payments,  discounted  at  the  Groups  incremental 
borrowing  rate  and  adjusted  for  time  value  of  money. 
The interest element of the finance cost  is charged to the 
Income Statement over the lease period so as to produce a 
constant periodic rate of interest on the remaining balance 
of the liability for each period. The lease liabilities are shown 
in Note 24.

The  Group  elects  to  apply  the  exemptions,  permitted  by 
IFRS  16,  for  lease  assets  and  liabilities  regarding  short-
term  and  low-value  leases.  Charges  recognised  in  the 
consolidated income statement in respect of these leases 
are not significant to the Group.

2.27. Prior year restatement

The  statement  of  financial  position  has  been  restated  for 
the finalisation of provisional fair values of the assets and 
liabilities  recognised  in  respect  of  the  JQG  and  Goijens 
acquisitions in 2022, following a PPA review during the IFRS 
3 hindsight period. See note 17 for further details.

3. FINANCIAL RISK MANAGEMENT

3.1. Financial Risk Factors

The Group and Company’s activities expose it to a variety of 
financial  risks:  market  risk,  credit  risk  and  liquidity  risk. The 
Group and Company’s overall risk management programme 
focuses  on  the  unpredictability  of  financial  markets  and 
seeks to minimise potential adverse effects on the Group and 
Company’s financial performance.

Risk management is carried out by the UK based management 
team under policies approved by the Board of Directors.

a) Market Risk

The  Group  is  exposed  to  market  risk,  primarily  relating  to 
interest  rate,  foreign  exchange  and  commodity  prices. 
The  Group  has  not  sensitised  the  figures  for  fluctuations 
in  interest  rates,  foreign  exchange  or  commodity  prices 
as  the  Directors  are  of  the  opinion  that  these  fluctuations 
would  not  have  a  significant  impact  on  the  Financial 
Statements  at  the  present  time.  The  Group  has  a  strong 
focus on operational gearing, allowing it to be flexible during 
economically  disruptive  events  however  the  Directors  will 
continue to assess the effect of movements in market risks 
on the Group’s financial operations and initiate suitable risk 
management measures where necessary.

b) Credit Risk

Credit  risk  is  the  risk  of  financial  loss  to  the  Group  if  a 
customer  or  counterparty  to  a  financial  instrument  fails 
to  meet  its  contractual  obligations,  and  arises  from  cash 

209

and cash equivalents, derivative financial instruments and, 
principally, from the Group’s receivables from customers.

Management  monitors  the  exposure  to  credit  risk  on  an 
ongoing  basis  and  have  credit  insurance  at  a  number  of 
its  subsidiaries.  The  Nordkalk  entities  don’t  hold  credit 
insurance as they have a stable customer base with minimal 
credit  losses.  No  credit  limits  were  exceeded  during  the 
period, and management does not expect any losses from 
non-performance by these counterparties.

Exposure to credit risk

The  carrying  amount  of  financial  assets  represents  the 
maximum  credit  exposure.  The  maximum  exposure  to 
credit risk at the reporting date was:

Credit risk associated with cash balances is managed and 
limited  by  transacting  with  financial  institutions  with  high-
quality credit ratings.

Trade and other receivables 

The  Group’s  exposure  to  credit  risk  stems  mainly  from 
the  individual  characteristics  of  each  customer.  However, 
management also considers the factors that could influence 
the credit risk of its customer base, including the default risk 
of the industry and country in which customers operate.

The Group has established a credit policy under which each 
new customer is analysed individually for creditworthiness, 
before the Group’s standard payment and delivery terms and 
conditions are offered to the customer. The Group’s review 
includes external ratings, when available, and in some cases 
bank references.

Most of the Group’s customers have been trading with the 
Group for years, and no major credit losses have occurred 
with these customers. Credit risk is monitored by grouping 
their  credit  characteristics, 
customers  according 
including whether they are individuals or legal entities and 
whether they are wholesale, retail or end-user customers, as 
well as by geographic location, industry and the existence of 
previous financial difficulties.

Derivatives

Subsidiary  currency  risks  are  hedged  by  the  parent  or 
ultimate parent acting as counterparty in currency forward 
deals.  External  currency  hedging  is  performed  by  finance 
and  treasury  functions  as  appropriate.  In  such  deals,  the 
counterparty is a bank or financial institution with a rating at 
least Baa3 from Moody’s rating agency. A comparable credit 
rating from a reputable credit rating agency is acceptable. 
Exceptions  may  be  granted  on  an  individual  basis  in  rare 
cases where a bank is chosen for geographical reasons, but 
does not fulfil the stipulated rating criteria.

Items  hedged  against  are  CO2  emission  rights,  forecast 
energy  consumption, 
in  foreign  currency  and 
forecast earnings.

c) Currency Risk

Following  the  Nordkalk  acquisition,  the  Group  is  exposed 
to  currency  risk  to  the  extent  that  there  is  a  mismatch 
between  the  currencies  in  which  sales  and  purchases  are 
denominated  and  the  respective  functional  currencies 
of  Group  companies.  The  functional  currencies  of  Group 
companies  are  primarily  the  Pound,  the  Euro,  the  Polish 
Zlothy (PLN) and the Swedish Krona (SEK). The currencies 
in which these transactions are primarily denominated are 
GBP,  EUR,  PLN,  and  SEK.  Additional  exposures  may  arise 
from purchase of fuel in USD.

At  any  point  in  time,  the  Group  hedges  on  average  60  to 
100 per cent of its estimated foreign currency exposure in 
respect of forecast sales and purchases over the following 
12-18 months. The Group uses forward exchange contracts 
to hedge its currency risk, with a maturity of up to 12 months 
from the reporting date.

Borrowings are, with a few exceptions, denominated in the 
subsidiaries domestic currencies.

In  respect  of  other  monetary  assets  and 
liabilities 
denominated in foreign currencies, the Group’s policy is to 
ensure that its net exposure remains at an acceptable level 
by  buying  or  selling  foreign  currencies  at  spot  rates  when 
necessary to address short-term imbalances.

Exposure to currency risk

Currency risk sensitivity to a +/- 10 per cent change in the 
exchange  rate  is  shown  for  the  net  currency  position  per 
currency. The summary of quantitative data relating to the 
Group’s exposure to currency risk as reported to the Group 
management is as follows.

d) Liquidity Risk

The  Group’s  continued  future  operations  depend  on  the 
ability  to  raise  sufficient  working  capital  through  the  issue 
of equity share capital or debt. The Directors are reasonably 
confident  that  adequate  funding  will  be  forthcoming  with 
which to finance operations owing to the continued support 
of  the  lenders  and  a  history  of  successful  capital  raises. 
Controls over expenditure are carefully managed.

The  outflows  disclosed  in  the  above  tables  represent  the 
contractual  undiscounted  cash  flows  relating  to  derivative 
financial liabilities held for risk management purposed and 
which are not usually closed out before contractual maturity. 

The  interest  payments  on  the  variable  interest  rate  loans 
in  the  table  above  reflect  market  forward  interest  rates  at 
the  reporting  date  and  these  amounts  may  change  in  line 
with changes in market interest rates. The future cash flows 
from  derivative  instruments  may  differ  from  the  amount 
in  the  above  table  as  interest  rates  and  exchange  rates 
change. With the exception of these financial liabilities, it is 
not  expected  that  the  cash  flows  included  in  the  maturity 
analysis  could  occur  significantly  earlier  or  at  significantly 
different amounts. 

3.2. Capital Risk Management

The  Group’s  objectives  when  managing  capital  are  to 
safeguard the Group’s ability to continue as a going concern, 
in  order  to  enable  the  Group  to  continue  its  construction 
material  investment  activities,  and  to  maintain  an  optimal 
capital structure to reduce the cost of capital.

In order to maintain or adjust the capital structure, the Group 
may adjust the issue of shares or sell assets to reduce debts.

The Group defines capital based on the total equity of the 
Company. The  Group  monitors  its  level  of  cash  resources 
available  against  future  planned  operational  activities  and 
the Company may issue new shares in order to raise further 
funds from time to time.

4. CRITICAL ACCOUNTING ESTIMATES

The preparation of the Financial Statements, in conformity 
with  UK  IASs,  requires  management  to  make  estimates, 
assumptions  and  judgements  that  affect  the  reported 
amounts  of  assets,  liabilities  and  disclosure  of  contingent 
assets and liabilities at the date of the Financial Statements 
and the reported amount of expenses during the year. Actual 
results may vary from the estimates used to produce these 
Financial Statements. 

Estimates  and 
judgements  are  continually  evaluated 
and  are  based  on  historical  experience  and  other  factors, 
including expectations of future events that are believed to 
be reasonable under the circumstances. 

Significant  items  subject  to  such  estimates,  assumptions 
and judgements include, but are not limited to:

a) Land and Mineral Reserves

The  determination  of  fair  values  of  land  and  mineral 
reserves are carried out by appropriately qualified persons 
in  accordance  with  the  Appraisal  and  Valuation  standards 
published  by  the  Royal  Institution  of  Chartered  Surveyors. 
To  determine  the  reserves,  management  will  engage  an 
independent  volume  and  tonnage  assessment,  which 
involves  a  topographic  survey  of  the  quarry  working, 
conducted in 3 dimensions for the date of the assessment 
using a computer aided design (CAD) system and a series 
of  theoretical  computer-generated  models,  taking 
into 
account  geotechnical  and  hydrogeological  factors,  as  well 
as ensuring that there is a practical extraction plan so that 
all  the  rock  can  be  recovered. This  produces  a  removal  of 
overburden model and removal of mineral model.  

Following  this,  the  volume  of  reserves  is  calculated  and 
converted to tonnes by multiplying the volume by the density 
of the mineral. This process is based upon factors such as 
estimates of commodity prices and geological assumptions 
and judgements. Additional estimates include future capital 
requirements and production costs. 

is  converted  to  tonnes  by 
The  volume  of  material 
multiplying  the  volume  by  the  density  of  the  mineral.  The 
final  tonnage  will  be  adjusted  to  exclude  material  that  is 
not  suitable  mineral  for  processing,  such  as  overburden, 
tips and weathered rock, to derive at the estimated volume 
of  mineral  reserves  remaining  at  the  date  of  assessment. 
This  process  is  based  upon  factors  such  as  estimates 
of  commodity  prices  and  geological  assumptions  and 
judgements.  Additional  estimates  include  future  capital 
requirements and production costs.

 
Notes to the financial statements

judgements  including  change  in  governments,  laws  and 
regulations, unknown factors and changes in technology.

The  restoration  provision  is  a  commitment  to  restore  the 
site to a safe and secure environment. These provisions are 
reviewed annually. 

d) Recognition of deferred tax assets

Uncertainty exists related to the availability of future taxable 
profit against which tax losses carried forward can be used, 
however deferred tax assets are recognised for unused tax 
losses  to  the  extent  that  it  is  probable  that  taxable  profits 
will  be  available  against  which  the  losses  can  be  utilised. 
Significant management judgement is required to determine 
the amount of  deferred tax assets that can be recognised, 
based  on  the  likely  timing  and  level  of  future  taxable 
profits, together with future tax planning strategies. Further 
information on income taxes is disclosed in Note 15.

e) Fair value of financial instruments

The  fair  values  of  financial  instruments  that  cannot  be 
determined  based  on  quoted  market  prices  and  rates 
are  established  using  different  valuation  techniques. 
The  Group  uses  judgement  to  select  methods  and  make 
assumptions that are mainly based on market conditions 
existing at the end of the reporting period. Factors regarding 
valuation  techniques  and  their  assumptions  could  affect 
the reported fair values. Further information on fair value 
of financial instruments is disclosed in note 33. 

5. DIVIDENDS

No  dividend  has  been  declared  or  paid  by  the  Company 
during the year ended 31 December 2023 (2022: nil).

6. SEGMENT INFORMATION

Management has determined the operating segments based 
on reports reviewed by the Board of Directors that are used 
to  make  strategic  decisions.  During  the  periods  presented 
the Group has three geographical regions, North West which 
comprises  of  PPG,  England,  Wales  and  Channel  Islands; 
West which comprises of Dimension Stone and Benelux; and 
North  East  which  comprises  of  Quicklime,  Nordics,  Poland 
and Baltics. Activities in the North West, West and North East 
Regions  relate  to  the  production  and  sale  of  construction 
material products and services.

The  PPAs  included  the  revaluation  of  land  and  minerals 
based on the estimated remaining reserves within St John’s, 
Les Vardes, Aberdo, Carrières du Hainaut, Harries, Nordkalk 
and  JQG  quarries.  These  are  then  valued  based  on  the 
estimated  remaining  life  of  the  mines  and  the  net  present 
value for the price per tonnage.

b) Estimated Impairment of Goodwill

Goodwill arising on business combinations is not amortised 
but is reviewed for impairment on an annual basis, or more 
frequently if there are indications that the goodwill may be 
impaired. Goodwill is allocated to groups of cash generating 
units according to the level at which management monitor 
that goodwill, which is at the level of operating segments.

Where the carrying value exceeds the estimated recoverable 
amount (being the greater of fair value less costs and value-
in-use),  an  impairment  loss  is  recognised  by  writing  down 
goodwill to its recoverable amount. When an impairment is 
recognised as an expense, it is not subsequently reversed.

To assess the value-in-use, the net cash flow forecasts are 
extrapolated  using  long-term  growth  rates  to  determine 
the  terminal  value.  These  net  cash  flow  forecasts  reflect 
volumes, sales prices, cost of sales and administration costs 
assumptions  in  addition  to  other  cash  flow  movements. 
Future  cash  flows, 
including  the  terminal  value,  are 
discounted  to  their  present  value  using  a  pre-tax  discount 
rate  takes  into  account  the  current  market  assessments 
of the time value of money and the certain risks for which 
the future cash flow estimates have not been adjusted. The 
future  cash  flow  estimates  exclude  net  cash  movement 
attributable to financing activities and income tax.  

The  impairment  test  process  requires  management  to 
make  significant  judgements  and  estimates  regarding  the 
valuation  models,  discount  rates  used  and  future  cash 
flows projected to be generated by the operating segment 
to  which  goodwill  has  been  allocated.  Further  information 
on the impairment assessment and key assumptions used 
is detailed in note 17.

The PPA assessments provide a reduction to the goodwill for 
each operating segment via the fair value assessment of the 
assets acquired in new entities as at the completion date. 

Goodwill has a carrying value of £169.7 million at 31 December 
2023 (31 December 2022: £115.2 million). Management has 
concluded  that  an  impairment  charge  was  not  necessary 
to  the  carrying  value  of  goodwill  for  the  period  ended  31 
December  2023  (31  December  2022:  £nil).  See  Note  2.6  to 
the Financial Statements.

c) Restoration Provision

The Group’s provision for restoration costs is an accounting 
estimate and has a carrying value at 31 December 2023 of 
£7.9 million (31 December 2022: £6.1 million) and relate to 
the removal of the plant and equipment held at quarries in the 
Channel Islands, United Kingdom and Northern Europe.

Under IFRS 3 – Business Combinations, acquisition costs have been expensed as incurred. Additionally, the Group incurred 
costs associated with obtaining debt financing, including advisory fees to restructure.

Acquisition related expenses include exclusivity, introducer, advisor, consulting, legal fees, accounting fees, insurance and other 
direct costs relating to acquisitions. During the year the Group acquired Juuan Dolomitik, Goijens, Retaining, Björka Mineral, ST 
Investicija, Beton and entered into agreements to acquire CRH’s European lime and industrial limestone assets which comprises 
the vast majority of the costs incurred during the year.

Amortisation  and  remeasurement  of  acquired  assets  are  non-cash  items  which  distort  the  underlying  performance  of  the 
businesses acquired. Amortisation of acquired assets arise from certain fair value uplifts resulting from the PPA. Remeasurement 
of acquired assets arises from ensuring assets from acquisitions are depreciated in line with Group policy. These are net of the 
deferred tax liability unwind on the asset fair value uplift.

Restructuring expenses relate to the reorganisation and integration of recently acquired subsidiaries, including costs associated 
with site optimisation, transitional salary costs, redundancies, severance & recruitment fees, and costs associated with financial 
reporting and system migrations. 

Share option expense is the fair value of the LTIP’s issued in 2021, refer to Note 29 more information.

Unwinding  of  discount  on  deferred  consideration  is  a  non-cash  adjustment  relating  to  deferred  consideration  arising  on 
acquisitions. 

Amortisation of finance costs is the amortisation of borrowing costs on the Syndicated Senior Credit Facility. These costs are 
amortised over a 5-year period.

Net other non-underlying expenses and gains include other advisory fees and other associated costs.

Legislation  to  increase  the  rate  of  corporation  tax  in  the  UK  from  1  April  2023  was  substantially  enacted  on  24  May  2021.  
The 25% rate has therefore been applied to any timing differences that are expected to reverse on or after 1 April 2023.

On 20 June 2023, Finance (No.2) Act 2023 was substantively enacted in the UK, introducing a global minimum effective tax 
rate of 15%. The legislation implements a domestic top-up tax and a multinational top-up tax, effective for accounting periods 
starting on or after 31 December 2023.  However, this legislation does not apply to the Group in the financial year beginning 1 
January 2024 as its consolidated revenue does not meet the legislation requirements of being greater than €750m in two of the 
four preceding years, the group will continue to monitor the legislation in future years.

Deferred tax assets and liabilities are offset to the extent that there is a legally enforceable right to offset current tax assets against 
current tax liabilities.

Deferred tax assets in relation to losses of £3.6 million (2022: £3.5 million) and other temporary differences of £6.1 million (2022: 
£3.4 million) have not been recognised due to uncertainty over their recoverability.

15. ASSET ACQUISITION

During  the  year,  the  Group  purchased  four  concrete  plants  located  on  the  Belgian  border  with  France,  along  with  operating 
permits, branding, and customer relations. These are collectively considered to be the acquisition of Betons. 

The Directors have treated the acquisition of Betons as an asset acquisition as the acquisition was not considered to meet the 
definition of a business combination under IFRS 3, and therefore they judged the fair value of the assets acquired to be equal to 
the fair value of the consideration. 

The amounts acquired as an asset acquisition are shown below:

Notes to the financial statements

An adjustment has been made to reflect the initial accounting 
for  the  acquisition  of  JQG  and  Goijens  by  the  Company, 
being the elimination of the investment in JQG and Goijens 
against the non-monetary assets acquired and recognition 
of goodwill. In 2023, the Company determined the fair value 
of the net assets acquired pursuant to the acquisition of JQG 
and Goijens, via a Purchase Price Allocation (‘PPA’) exercise.  
For  JQG,  the  PPA  determined  a  decrease  of  £33.1  million 
of goodwill with the corresponding movement to uplift the 
value of the land and minerals and other intangibles, this is 
net off by a deferred tax liability on the PPA of £9.6 million. 
For Goijens, the PPA determined a decrease of £3.5 million 
of goodwill with the corresponding movement to uplift the 
value  of  the  Customer  relations  and  Land  and  Buildings, 
this is net off by a deferred tax liability on the PPA of £0.9 
million. This adheres to the requirements of IFRS 3 and this 
adjustment has been made as a prior year adjustment.

In  2022,  PPA  adjustments  were  made  to  acquisitions  in 
2021, Nordkalk and BMix, during the measurement period 
and the adjustment of £235 million was made as a separate 
line item rather than as a prior year adjustment in line with 
IFRS 3. No adjustment has been made to align with IFRS 3 
as any restatement would only affect comparative opening 
balances in this annual report and accounts such that the 
matter has no ongoing relevance. The Group didn’t include 
provisional  adjustments  for  the  reduction  in  goodwill  in 
the  year  ended  31  December  2021,  which  is  when  the 
assets  were  acquired,  leaving  the  initial  accounting  for 
these assets incomplete as they were pending completion 
of  the  PPA  during  the  measurement  period.  The  Group 
refrains  from  making  internal  provisional  adjustments  to 
goodwill given the subjectivity and difficulty in quantifying 
the  potential  uplifts.  All  PPA  adjustments  to  goodwill  are 
provided by an independent third party and are completed 
during the measurement period in line with IFRS 3.

The PPA for the acquisitions post July 2023, being Björka  
and ST Investicija, will be prepared within the measurement 
period.

The Goodwill allocated to each region is shown below:

The intangible asset classes are:

•  Goodwill is the excess of the consideration transferred 
and  the  acquisition  date  fair  value  of  any  previous 
equity interest in the acquire over the fair value of the 
net identifiable assets.

•  Customer  relations  is  the  value  attributed  to  the  key 

customer lists and relationships.

Intellectual property is the patents owned by the Group.

• 
•  Research  and  development  is  the  acquisition  of  new 
technical  knowledge  and  trying  to  improve  existing 
processes or products or; developing new processes or 
products.

•  Branding  is  the  value  attributed  to  the  established 

company brand.

•  Other  intangibles  consist  of  capitalised  development 
costs for assets produced that assist in the operations 
of the Group and incur revenue.

Amortisation of intangible assets is included in cost of sales 
on  the  Income  Statement.  Development  costs  have  been 
capitalised in accordance with the requirements of IAS 38 
and  are  therefore  not  treated,  for  dividend  purposes,  as  a 
realised loss.

Impairment tests for goodwill

Goodwill arising on business combinations is not amortised 
but is reviewed for impairment on an annual basis, or more 
frequently if there are indications that the goodwill may be 
impaired. Goodwill is allocated to groups of cash generating 
units according to the level at which management monitor 
that goodwill, which is at the level of operating segments.

A  total  of  eighteen  operating  segments  are  considered  to 
be Ronez in the Channel Islands; Topcrete, Poundfield, CCP, 
Rightcast, Retaining, Harries and Johnston in the UK; CDH, 
Stone,  GduH,  B-Mix,  Goijens  and  Betons  in  Belgium;  and 
Quicklime, Nordics, Baltics and Poland in Northern Europe. 
The operating segments are then allocated to regions.

Key assumptions

Sensitivity

The  key  assumptions  used  in  performing  the  impairment 
review are set out below:

Cash flow projections

The key assumptions and methodology used in respect of 
the operating segments are consistent with those described 
above.  The  values  applied  to  each  of  the  key  estimates 
and  assumptions  are  specific  to  the  individual  operating 
segment  and  are  based  on  past  experience  and  forecast 
future  trading  conditions.  The  cash  flows  and  terminal 
value were projected in line with the methodology disclosed 
above.

Long-term growth rates

The Group has applied sensitivities to assess whether any 
reasonable  possible  changes  in  assumptions  could  cause 
an impairment that would be material to these consolidated 
Financial  Statements.  The  table  below 
identifies  the 
amounts by which each of the following assumptions would 
decline or increase to arrive at a zero excess of the present 
value of future cash flows over the book value of net assets 
in  the  two  operating  segments  selected  for  sensitivity 
analysis disclosures:

Reduction in cash flows

6.0% - 7.0%

Increase in discount rate

2.0% - 3.7%

Cash  flow  projections  are  prudently  based  on  2  per  cent 
(2022: 2 per cent) and therefore provides plenty of headroom.

Reduction in growth rate

2.0%

Discount rate

Forecast  cash  flows  for  each  operating  segment  have 
been discounted at rates of 9.30 per cent to 12.24 per cent 
(2022: 10 per cent); which was calculated based on market 
participants’ cost of capital and adjusted to reflect factors 
specific to each operating segment.

This  demonstrated  that  a  1.0%  (2022:  1.0%)  increase  in 
the  discount  rate  would  not  cause  an  impairment  and  the 
annual growth rate is assumed to be 2.0% (2022: 2.0%).

The Directors have therefore concluded that no impairment 
to goodwill is necessary.

In  July  2021,  the  Group  entered  into  a  new  Syndicated  
Senior Credit Facility of up to £305 million (the ‘Legacy Debt’) 
led  by  Santander  UK  and  including  several  major  UK  and 
European banks. The Legacy Debt, which comprises a £205 
million  committed  term  facility,  a  £100  million  revolving 
facility  commitment  and  a  further  £100  million  accordion 
option. This new facility replaces all previously existing bank 
loans within the Group. 

The  Legacy  Debt  is  secured  by  a  floating  charge  over  the 
assets  of  SigmaFin  Limited,  Carrieres  du  Hainaut  and 
Nordkalk  and  is  secured  by  a  combination  of  debentures, 
security  interest  agreements,  pledges  and  floating  rate 
charges over the assets of SigmaRoc plc, SigmaFin Limited, 
B-Mix,  Carrieres  du  Hainaut  and  Nordkalk.  Interest  is 
charged at a rate between 1.85% and 3.35% above SONIA 

(‘Interest Margin’), based on the calculation of the adjusted 
leverage ratio for the relevant period. For the period ending 
31 December 2023 the Interest Margin was 2.35%.

On  22  November  2023  the  Company  entered  into  a  new 
syndicated  senior  credit  facility  of  up  to  €750  million  (the 
‘New  Debt  Facilities’)  led  by  Santander  UK  and  BNPP,  with 
the  syndicate  including  several  major  UK  and  European 
banks and a further €125 million bridge loan (‘Bridge Loan’). 
The New Debt Facilities comprise a €600 million committed 
term  facility,  €150  million  revolving  credit  facility  and  a 
further €100 million uncommitted accordion. The New Debt 
Facilities are conditional on the completion of the acquisition 
of  the  CRH  Deal  1,  following  completion,  the  Legacy  Debt 
will  be  repaid  in  full.    As  of  31  December  2023,  the  Group 
hadn’t drawn any funds from the New Debt Facilities.

As at 1 January

Acquired on business combination

Addition/(Deduction)

The provision total is made up of £632,011 as a restoration 
provision for the St John’s and Les Vardes sites; £86,812 for 
the Aberdo site; £172,303 for quarries in Wales; £6.7 million 
for the Nordkalk sites; and £338,943 for the Johnston sites 
which are all based on the removal costs of the plant and 
machinery  at  the  sites  and  restoration  of  the  land.  Cost 
estimates in Jersey and Guernsey are not increased on an 
annual  basis  –  there  is  no  legal  or  planning  obligation  to 
enhance the sites through restoration. The commitment is 
to restore the site to a safe environment; thus the provision 
is  reviewed  on  an  annual  basis.  The  estimated  expiry  on 
the quarries ranges between 5 – 35 years.    

Of  the  remaining  amount,  £242,000  is  to  cover  the  loss 
on  the  Holcim  contract  in  GduH,  £62,000  for  legal  fees, 
£1.69 million for other restructuring costs in the Nordkalk 
entities, £3.19 million is the provision for early retirement 
in  Belgium,  where  salaried  workers  can  qualify  for  early 
retirement based on age and £70,000 for early retirement 
in the Nordkalk entities. The provision for early retirement 
consists of the estimated amount that will be paid by the 
employer to the “early retired workers” till the age of the full 
pension. Refer to Note 26 for more information.

The  future  reclamation  cost  value  is  discounted  by  8% 
(2022  8%)  which  is  the  weighted  average  cost  of  capital 
within the Group.

Defined benefit plans

The Group has group insurance plans for some of its Belgian, 
Swedish  and  Polish  employees  funded  through  defined 
payments  to  insurance  companies.  The  Belgian  pension 
plans  are  by  law  subject  to  minimum  guaranteed  rates  of 
return.  In  the  past  the  minimum  guaranteed  rates  were 
3.25%  on  employer  contributions  and  3.75%  on  employee 
contributions.  A  law  of  December  2015  (enforced  on  1 
January 2016) modifies the minimum guaranteed rates of 
return applicable to the Group’s Belgian pension plans. For 
insured plans, the rates of 3.25% on employer contributions 

FINANCIAL REPORTSIGMAROC ANNUAL REPORT 2023and  3.75%  on  employee  contributions  will  continue  to 
apply  to  the  contributions  accumulated  before  2016.  For 
contributions  paid  on  or  after  1  January  2016,  a  variable 
minimum  guaranteed  rate  of  return  with  a  floor  of  1.75% 
applies.  The  Group  obtained  actuarial  calculations  for  the 
periods reported based on the projected unit credit method. 

The  Swedish  plan  provides  an  old-age  pension  cover  for 
plan members whereas plan members receive a lump sum 

payment upon retirement in the Polish plan. Both Swedish 
and Polish plans are based on collective labour agreements. 
Through its defined benefit plans, the Group is exposed to 
a  number  of  risks.  A  decrease  in  bond  yields  will  increase 
the plan liabilities. Some of the Group’s pension obligations 
are linked to inflation and higher inflation will lead to higher 
liabilities. The majority of the plans obligations are to provide 
benefits for the life of the plan member, so increases in life 
expectancy will result in an increase in the plans liabilities.

Post-retirement benefits

The  Group  operates  both  defined  benefit  and  defined 
contribution pension plans.

Pension  plans  in  Belgium  are  of  the  defined  benefit  type 
because of the minimum promised return on contributions 
required  by  law.  The  liability  or  asset  recognised  in  the 
Statement of Financial Position in respect of defined benefit 
pension  plans  is  the  present  value  of  the  defined  benefit 
obligation at the end of the reporting period less the fair value 
of plan assets. The defined benefit obligation is calculated 
annually by independent actuaries using the projected unit 
credit  method.  The  present  value  of  the  defined  benefit 
obligation is determined by discounting the estimated future 
cash outflows using interest rates of high-quality corporate 
bonds  that  are  denominated  in  the  currency  in  which  the 
benefits will be paid, and that have terms approximating to 

the terms of the related obligation. The net interest cost is 
calculated by applying the discount rate to the net balance 
of  the  defined  benefit  obligation  and  the  fair  value  of  plan 
assets. This  cost  is  included  in  employee  benefit  expense 
in  the  Income  Statement.  Remeasurement  gains  and 
losses arising from experience adjustments and changes in 
actuarial assumptions are recognised in the period in which 
they occur, directly in other comprehensive income. They are 
included in retained earnings in the Statement of Changes in 
Equity and in the Statement of Financial Position.

For defined contribution plans, the Group pays contributions 
to publicly or privately administered pension insurance plans 
on a mandatory, contractual or voluntary basis. The Group 
has no further payment obligations once the contributions 
have  been  paid.  The  contributions  are  recognised  as 
employee benefit expense when they are due.

32. EARNINGS PER SHARE

The  calculation  of  the  total  basic  earnings  per  share  of 
1.98  pence  (2022:  4.89  pence)  is  calculated  by  dividing 
the  profit  attributable  to  shareholders  of  £13,534  million 
(2022: £31,238 million) by the weighted average number of 
ordinary shares of 684,973,893 (2022: 638,243,627) in issue 
during the period.

shareholders of £13,534 million (2022: £31,238 million) by 
the  weighted  average  number  of  ordinary  shares  in  issue 
during  the  period  plus  the  weighted  average  number  of 
share options and warrants to subscribe for ordinary shares 
in  the  Company,  which  together  total  714,091,517  (2022: 
667,430,527).  The  weighted  average  number  of  shares  is 
the  opening  balance  of  ordinary  shares  plus  the  weighted 
average of 46,727,549 shares.

Diluted  earnings  per  share  of  1.90  pence  (2022:  4.68 
pence)  is  calculated  by  dividing  the  profit  attributable  to 

Details of share options that could potentially dilute earnings 
per share in future periods are disclosed in Note 29.

33.  FAIR  VALUE  OF  FINANCIAL  ASSETS  AND  LIABILITIES 
MEASURED AT AMORTISED COSTS

The  following  table  shows  the  carrying  amounts  and  fair 
values  of  the  financial  assets  and  liabilities,  including  their 
levels in the fair value hierarchy. It does not include fair value 
information  for  financial  assets  and  financial  liabilities  not 
measured at fair value if the carrying amount is a reasonable 
approximation of fair value. 

Items where the carrying amount equates to the fair value are 
categorised to three levels:

• 

• 

• 

Level  1  inputs  are  quoted  prices  (unadjusted)  in  active 
markets  for  identical  assets  or  liabilities  that  the  entity 
can access at the measurement date.

Level 2 inputs are inputs other than quoted prices included 
within Level 1 that are observable for the asset or liability, 
either directly or indirectly.

Level  3  inputs  are  unobservable  inputs  for  the  asset  or 
liability.

Items which are categorised as Level 2 financial assets and 
liabilities are forward exchange contracts and these are valued 
using the year end exchange rate for the relevant currencies.
