chairman’s statement
this has been a good year of progress the board expects 
proﬁtable growth during ﬁnancial year 2008 
“
”
introduction
this has been a good year of progress and gives a ﬁrm basis for optimism about the future 
i am pleased to announce that the management team has again met expectations and continued 
to deliver growth in proﬁt in particular a 54 increase in ebitda and a 46 increase in adjusted 
diluted eps
this year has been the most signiﬁcant in terms of strategic positioning since the formation of 
the group we acquired a wafer reclaim facility in arizona us during february of this year which 
gives us further access to a very exciting market
we also saw the exit of our original venture capital funding partner apax partners limited “apax” 
on behalf of all at pure wafer i would like to thank apax for their continued support from formation 
until the day they exited without apax’s initial ﬁnancial and management support to one of the 
uk’s largest ever venture capital backed greenﬁeld startups pure wafer would not be in the 
enviable position that we ﬁnd ourselves in today
shareholders may wish to note that the group’s results have been signiﬁcantly affected by 
movements in the us dollar i draw your attention to the ﬁnance director’s analysis in the ﬁnancial 
review and point out that movements in the exchange rate this year have had a negative impact 
of approximately £14m on our pretax proﬁts it is worth noting that the us acquisition will 
reduce our exposure to currency movements on new business in our largest market

management
we have further strengthened our board this year by the appointment of paul dolan a chartered 
accountant and formerly a partner of deloitte as nonexecutive director following the departure 
of the apax representative john samuel
our senior management team is also beneﬁting from the wealth of experience and skills acquired 
as part of the purchase of our us facility the senior management of the us site has many years 
experience of the semiconductor and wafer reclaim industry between them in many key areas 
from manufacturing and process development through to sales
i shall take this opportunity to welcome our new colleagues in arizona and all new employees in 
swansea and to congratulate them on joining this successful results driven group
i would like to thank the entire team across both sites led by keith baker for their hard work and 
continued delivery of results i am conﬁdent that they will continue to strive for success and 
achievement in the current ﬁnancial year
outlook
the board expects proﬁtable growth during the next ﬁnancial year as the group exploits its strong 
position in the expanding global 300mm wafer reclaim market the results for the ﬁrst quarter 
of ﬁnancial year 2008 are expected to be affected by technical difﬁculities slowing down the ramp 
of a new product line with a single customer with support from the customer we have recently 
developed an improved manufacturing process that we believe will enable us to run this product 
in higher volume 
we look to the future with conﬁdence

chief executive’s review
highlights
  another year of record 300mm 
reclaim volumes
  further capacity increases 
underway
  arizona site performed in line 
with expectations
  new customers on board
  market growth continues
operational review
volumes for all wafer sizes were increased during the year with 300mm volumes up by 53 
and 200mm volumes up by 131 enhanced by our north american acquisition the month 
of june 2007 saw a record for 300mm wafer reclaim at pure wafer
we are planning to further increase our 300mm wafer reclaim capacity at the swansea site 
to 100000 wafers per month at the end of the ﬁnancial year to june 2008 through further 
process development and capital expenditure such expenditure will be fully funded through 
cash generation and existing facilities
prescott site arizona us
the development of the us site that we acquired in february this year continues in line with our 
original plans the existing business is cash positive and proﬁtable on an operating proﬁt level 
i am pleased to announce that the transfer of the 300mm technology from our swansea site is 
progressing satisfactorily the ﬁrst 300mm wafer reclaim line is now substantially in place and the 
installation is running according to plan both in terms of cost and time we expect capacity of 
this 300mm line to be approximately 20000 wafers per month at the end of our ﬁnancial year 
to june 2008
market and products
our customer base has signiﬁcantly increased as a result of the acquisition more than doubling 
to over 80 customer sites and i would like to take this opportunity to welcome all new pure wafer 
customers and to thank them for their support through the change of ownership of the us plant
smaller diameter wafer reclaim 100mm 125mm and 150mm is a new addition to the pure wafer 
product portfolio and has been gained through our us acquisition these are proﬁtable product 
lines with well established processes in a developed market place
the current slowdown within the semiconductor industry is having the impact of reducing the 
demand for smaller diameter wafer reclaim as customers look to switch towards the more efﬁcient 
300mm manufacturing with the comprehensive product offerings within the business we are well 
placed to support our customers through this transition
both the swansea site and the newly acquired arizona site 
performed in line with our expectations 
“

0purar07frontindd   4 16102007   183450 05 pure wafer plc annual report and accounts 2007
as expected the competitive landscape is increasing as the market continues its growth with 
two new 300mm competitors emerging in taiwan and existing competitors continuing to increase 
capacity we feel that we are well placed with our multisite locations leading technology and 
wealth of experience to maintain our position as a leading supplier of 300mm products
during the year we shipped in high volume our new 50nm product offering this product is very 
much in the early stages of product ramp but we remain optimistic about the future potential of 
this product line
new technology
we are continuing to look at opportunities outside of wafer reclaim following the successful 
introduction of our 50nm product we are conﬁdent that there are many more ways that we can 
leverage our worldclass cleanrooms and silicon polishing expertise in order to continue to deliver 
increasing shareholder value in the future

lines with the acquisition 150mm diameter and smaller and continued to organically grow 
existing business wafer volumes of each size continued to increase and each size remains proﬁtable
margins were impacted by the weaker us dollar in the year and the acquisition of a site currently 
without the beneﬁt of the higher margin 300mm volumes
despite the challenges thrown up from the increase in customer speciﬁcations as the requirement 
for smaller and lower numbers of particles per wafer continues to progress the consolidated 
group has managed to continue to reduce the cost per 300mm equivalent wafer we are continuing 
our focus on cost reduction and are pursuing production cost per wafer savings across both 
manufacturing sites

cash ﬂow and capital expenditure
the group continues to be increasingly cash generative on an operating cash level with a net 
cash inﬂow from operating activities of £426m 2006 £268m
during the period capital equipment with the value of £760m was acquired with £564m 
of this expenditure happening at the uk site the construction in progress value £189m 
relates to the upgrade of the us site and installation of a 300mm wafer reclaim line 
construction is nearing completion and is currently running broadly in line with the 
ﬁnancial budget
taxation
there is no tax charge across the group as taxable proﬁts generated within the uk have been 
set against tax losses brought forward the directors are conﬁdent of the trading and ﬁnancial 
prospects of the group so based upon shortterm forecasts the remaining available unutilised 
uk tax losses £286m were recognised in the balance sheet during 2007 this will have the 
impact in future periods of showing a uk tax charge in the proﬁt and loss account but with 
no cash impact until the deferred tax asset has unwound
acquisition
the total purchase cost of us1120m comprised a payment of us750m on completion 
us175m interest free deferred consideration falling due after 12 months and a further 
us195m interest free deferred consideration falling due after 24 months
the initial purchase payment of 750m was funded through a four year variable rate 
interest loan from royal bank of scotland “rbs” that was ﬁxed through an interest swap 
at the time of drawdown to a rate of 694 per annum the deferred consideration payments 
are not contingent and accordingly are backed by a letter of credit from rbs the two deferred 
consideration payments have been discounted to present values and are reﬂected in the 
accounts as a ﬁnancial liability within net funds as the amounts have been discounted 
an imputed noncash interest charge is levied through the proﬁt and loss account each 
period until the deferred considerations are paid
financial review continued
the group continues to be increasingly cash generative on an 
operating cash level

international financial reporting standards “ifrs”
following a european union regulation ias regulation ec 16062002 issued in june 2002 
and aim notice 22 pure wafer plc is required to prepare its consolidated ﬁnancial statements 
under international financial reporting standards with effect for the year ending 30 june 2008
this is the last set of pure wafer plc ﬁnancial statements prepared under uk gaap  the group 
adopted ifrs on 1 july 2007 and consequently future ﬁnancial reporting will be under ifrs 
the group will hold a brieﬁng at the annual general meeting to update stakeholders on the 
impact of adoption of ifrs
eps and dividend
diluted eps for the period was 2059p 2006 1442p which included the effect of the  
recognition of the uk deferred tax asset and frs20 share option charge excluding these 
items adjusted diluted eps for the group was 1111p 2006 763p
as at 30 june 2007 the group did not have sufﬁcient distributable reserves for the board to 
be able to recommend a dividend accordingly no dividend is payable for this ﬁnancial year
following the end of the ﬁnancial year the subsidiary company pure wafer international limited 
completed a capital reduction which is expected to leave the group with distributable reserves

the group accounts comprise the consolidation of the accounts of the group and all its subsidiary undertakings after eliminating intragroup 
transactions as provided by section 230 of the companies act 1985 a separate proﬁt and loss account for the company is not disclosed
intangible ﬁxed assets – goodwill
businesses acquired have been dealt with in the consolidated accounts using acquisition accounting upon the acquisition of a business 
the fair values that reﬂect the condition at the date of acquisition are attributed to the identiﬁable assets and liabilities acquired adjustments 
are also made to bring the accounting policies of the businesses acquired into alignment with those of the group where the consideration 
paid exceeds the fair value of the net assets acquired the difference is treated as goodwill
goodwill arising on the acquisition made during the year has been capitalised and is being amortised over 20 years on a straight line basis 
the amortisation period is the length of time over which the directors believe the group will draw economic beneﬁt from the acquisition
tangible ﬁxed assets
the cost of ﬁxed assets is their purchase cost together with any incidental costs of acquisition
depreciation is calculated so as to write off the cost or valuation of tangible ﬁxed assets less their estimated residual values on a straight line 
basis over the expected useful economic lives of the assets concerned no depreciation is charged until the assets have been commissioned 
and are in use
the principal rates used are as follows
leasehold buildings   15 years
plant and machinery  10 years
fixtures ﬁttings and equipment 5 years
it equipment   3 years
motor vehicles   3 years

impairment of ﬁxed assets
impairment is calculated as the difference between the carrying value and the recoverable value of incomegenerating units recoverable value 
is the higher of net realisable value and estimated value in use at the date the impairment loss is recognised value in use represents the present 
value of expected future discounted cash ﬂows if incurred impairment is recognised in the proﬁt and loss account
stocks and work in progress
stocks and work in progress are stated at the lower of cost and net realisable value in general cost is determined on a ﬁrst in ﬁrst out basis 
and includes transport and handling costs in the case of manufactured products cost includes all direct expenditure and production overheads 
based on the normal level of activity net realisable value is the price at which stocks can be sold in the normal course of business after allowing 
for the costs of realisation and where appropriate the cost of conversion from their existing state to a ﬁnished condition provision is made 
where necessary for obsolete slowmoving and defective stocks
taxation
deferred tax is recognised in respect of all timing differences that have originated but not reversed at the balance sheet date where transactions 
or events that result in an obligation to pay more tax in the future or a right to pay less tax in the future have occurred at the balance sheet date
a net deferred tax asset is recognised only when on the basis of all available evidence it can be regarded as more likely than not that there 
will be suitable taxable proﬁts against which to recover carried forward tax losses andor from which the future reversal of underlying timing 
differences can be deducted
deferred tax is measured at the average tax rates that are expected to apply in the periods in which the timing differences are expected 
to reverse based on tax rates and laws that have been enacted or substantively enacted by the balance sheet date deferred tax is measured 
on a nondiscounted basis 
government grants
government grants in respect of capital expenditure are credited to a deferred income account which is released to the proﬁt and loss account 
over the expected lives of the assets concerned all other grants are credited to the proﬁt and loss account on a receivable basis
translation of foreign currencies
monetary assets and liabilities denominated in foreign currencies are translated to sterling at the rate of exchange ruling at the balance sheet 
date except where covered by forward currency transactions when they are translated at the contracted rates other assets are translated to 
sterling at the rates of exchange ruling at the date of purchase or where covered by forward currency transactions at the contract rate 
the proﬁt and loss accounts and cash ﬂow statements of nonsterling denominated group companies are translated to sterling the group’s 
presentation currency at average rates of exchange in each period assets and liabilities of those companies are translated at rates of exchange 
ruling at the balance sheet date the differences between retained proﬁts and losses translated at average and closing rates are taken to 
reserves as are differences arising on the retranslation to sterling of nonsterling denominated net assets at the beginning of the year 
research and development expenditure
all research and development costs are written off in the year in which they are incurred with the exception of certain major product development 
projects relating to new products or processes where reasonable certainty exists as regards technical and commercial viability such expenditure is 
capitalised and amortised over the expected product life commencing in the year when sales of the product are made for the ﬁrst time
leased assets
where assets are ﬁnanced by leasing agreements which give substantially the same rights as ownership “ﬁnance leases” the assets are treated 
as if they had been purchased outright at the capital value of the assets and the corresponding leasing commitments are shown as obligations 
to the lessor the capital element of lease payments is applied to reduce the outstanding obligations and the interest is charged to the proﬁt 
and loss account over the period of the lease other rentals are charged wholly to the proﬁt and loss account
financial instruments
the only derivative instruments utilised by the group are forward exchange contracts forward exchange contracts are used for hedging 
purposes to alter the risk proﬁle of an existing underlying exposure of the group in line with the group’s risk management policies

deferred taxation
current year proﬁts have been relieved against brought forward tax losses as the directors are conﬁdent of the trading and ﬁnancial prospects 
of the group based upon shortterm forecasts a deferred tax asset has been recognised for part of the unutilised tax losses at 30 june 2007 
to the extent that the asset is regarded as recoverable the quantum of the deferred tax asset will be reassessed annually
the pure wafer group headed by pure wafer plc has approximately £239m 2006 £251m of taxation losses of this £65m 2006 £51m 
has been utilised to eliminate the requirement for a deferred tax liability £167m 2006 £63m has been recognised as a deferred tax asset

announcements were made in the march 2007 budget that the following changes to the corporation tax legislation would be enacted in the 
2007 and 2008 finance acts
1 the reduction of the main rate of corporation tax to 28 from 1 april 2008 onwards finance act 2007
2 the abolition of balancing adjustments on the sale of industrial buildings from 21 march 2007 onwards finance act 2007 and
3 the phasing out of industrial buildings allowances from 1 april 2008 onwards finance act 2008 
at the balance sheet date the finance act 2007 had been substantially enacted and the numbers reported in the ﬁnancial statements have 
therefore been impacted as follows
1  the change in the main rate of corporation tax has resulted in the deferred tax asset recognised at 30 june 2007 being reduced 
by £03m and
2 the abolition of balancing adjustments on the sale of industrial buildings has had no impact on the reported ﬁgures
the changes to be enacted in the finance act 2008 would however reduce the deferred tax asset recognised at 30 june 2007 by £01m

the group’s ﬁnancial instruments other than derivatives comprise borrowings some cash and various items such as trade debtors and trade 
creditors which arise directly from its operations 
the group also enters into forward foreign currency transactions the purpose of which is to manage the currency risks arising from the group’s operations
it is and has been throughout the period the group’s policy that no trading in ﬁnancial instruments is undertaken
the group has borrowings at ﬁxed rates only where a variable rate loan is taken out an interest rate swap is taken out to ﬁx the rate on the 
date of drawdown accordingly the group is not subject to interest rate risk on existing borrowings
the main risks arising from the group’s ﬁnancial instruments are foreign currency risk and liquidity risk the board reviews and agrees policies 
for managing these risks as summarised below
foreign currency risk
over 95 of the group’s sales are invoiced in us dollars the majority of the group’s costs are incurred in sterling the group uses forward 
currency contracts and any other similar derivative instruments based on the forecast exposure for each quarter to manage the risk
liquidity risk
the group constantly reviews its borrowing requirements to ensure adequate funds are available for ongoing operations this is achieved 
through the preparation of cash ﬂow forecasts with comparison to actual performance
credit risk
the group has procedures in place to mitigate credit risk including credit checks on potential new customers review of the ﬁnancial position 
of existing customers and a regular review of the ageing of debts

these services enable semiconductor manufacturers to gain efﬁciencies through the 
increased reuse of silicon test wafers within their production processes

our history
pure wafer was established in 
2000 by a management team widely 
experienced in the semiconductor 
industry with the backing of strategic 
investment from venture capital and 
industry partners 
the group ﬂoated on aim in 
december 2004 and in february 
2007 pure wafer completed the 
acquisition of a wafer reclaim 
facility in arizona us
the group is now an industry leading 
provider of wafer reclaim services
 
our facilities – uk
the uk business operates from a 
state of the art purpose built facility 
situated in a new technology park 
in swansea wales and is the most 
advanced plant of its kind in europe 
the size of the facility is in excess of 
4500m
2
 and includes over 2000m
2
 
of production cleanrooms 
we have installed the latest generation 
of tools available on the market 
with the most advanced equipment 
as used by ic and prime silicon 
producers with the highest technical 
speciﬁcations we are positioned to 
offer the most effective wafer reclaim 
service to our customers with minimal 
silicon removal this enables our 
customers to maximise the number 
of times a test wafer can be reclaimed
our facilities – us
the facility in prescott arizona 
was constructed in 1997 and 
has received in excess of 40m 
of investment since then this high 
volume hightech fab has been 
focussed on provision of 100mm 
125mm 150mm and 200mm 
wafer reclaim services but following 
the acquisition by pure wafer in 
february 2007 capability to reclaim 
300mm wafers has been installed
wafer reclaim
during the many stages of 
the manufacturing process of 
semiconductors large quantities 
of test wafers are used to check 
the accurate calibration of 
equipment these test wafers 
are a key consumable in the 
manufacture of semiconductors 
and the ability to reclaim them 
through pure wafer’s advanced 
process provides manufacturers 
with the opportunity to reduce costs
the semiconductor industry is currently 
seeing a rapid transition to 300mm 
wafers in order for manufacturers to 
continue to increase functionality at a 
reduced cost the industry has sought 
to increase the size of wafers on which 
semiconductors are manufactured 
300mm wafer processing now 
represents the fastest growing area 
of the semiconductor industry
however wafer reclaim is a 
highly specialised and technically 
sophisticated process only a few 
companies worldwide are able to 
meet the exacting standards required 
by semiconductor manufacturers 
for the reclaim of 300mm wafers 
of which pure wafer is one
our process
at pure wafer our process for 
reclaiming test wafers involves 
the following key stages 
  inspection of the wafers for 
defects and classiﬁcation by type 
of contaminant to be removed 
  submersion in a precise mix 
of chemicals appropriate to 
remove the contaminant 
  assessment of ﬂatness and 
correction of defects using 
pure wafer’s advanced 
polishing processes 
 cleaning and drying 
  final quality inspection 
and packaging for return 
to the customer
the company has an established track record one of the world’s most advanced wafer 
reclaim facilities and a blue chip customer base that includes some of the world’s 
largest semiconductor manufacturers and independent foundries as a business 
partner pure wafer works with its customers to design and develop a service that 
delivers reclaimed wafers to the exact speciﬁcations and high standards required 
by today’s leading semiconductor manufacturers

Summary:
 02 pure wafer plc annual report and accounts 2007
chairman’s statement
this has been a good year of progress the board expects 
proﬁtable growth during ﬁnancial year 2008 
“
”
introduction
this has been a good year of progress and gives a ﬁrm basis for optimism about the future 
i am pleased to announce that the management team has again met expectations and continued 
to deliver growth in proﬁt in particular a 54 increase in ebitda and a 46 increase in adjusted 
diluted eps
this year has been the most signiﬁcant in terms of strategic positioning since the formation of 
the group we acquired a wafer reclaim facility in arizona us during february of this year which 
gives us further access to a very exciting market
we also saw the exit of our original venture capital funding partner apax partners limited “apax” 
on behalf of all at pure wafer i would like to thank apax for their continued support from formation 
until the day they exited without apax’s initial ﬁnancial and management support to one of the 
uk’s largest ever venture capital backed greenﬁeld startups pure wafer would not be in the 
enviable position that we ﬁnd ourselves in today
shareholders may wish to note that the group’s results have been signiﬁcantly affected by 
movements in the us dollar i draw your attention to the ﬁnance director’s analysis in the ﬁnancial 
review and point out that movements in the exchange rate this year have had a negative impact 
of approximately £14m on our pretax proﬁts it is worth noting that the us acquisition will 
reduce our exposure to currency movements on new business in our largest market

management
we have further strengthened our board this year by the appointment of paul dolan a chartered 
accountant and formerly a partner of deloitte as nonexecutive director following the departure 
of the apax representative john samuel
our senior management team is also beneﬁting from the wealth of experience and skills acquired 
as part of the purchase of our us facility the senior management of the us site has many years 
experience of the semiconductor and wafer reclaim industry between them in many key areas 
from manufacturing and process development through to sales
i shall take this opportunity to welcome our new colleagues in arizona and all new employees in 
swansea and to congratulate them on joining this successful results driven group
i would like to thank the entire team across both sites led by keith baker for their hard work and 
continued delivery of results i am conﬁdent that they will continue to strive for success and 
achievement in the current ﬁnancial year
outlook
the board expects proﬁtable growth during the next ﬁnancial year as the group exploits its strong 
position in the expanding global 300mm wafer reclaim market the results for the ﬁrst quarter 
of ﬁnancial year 2008 are expected to be affected by technical difﬁculities slowing down the ramp 
of a new product line with a single customer with support from the customer we have recently 
developed an improved manufacturing process that we believe will enable us to run this product 
in higher volume 
we look to the future with conﬁdence
