                            SPIRENT COMMUNICATIONS PLC

            PRELIMINARY RESULTS FOR THE YEAR ENDED 31 DECEMBER 2006

London, UK - 1 March 2007 - Spirent Communications plc ("Spirent" or "the
Group")

(LSE: SPT; NYSE: SPM), a leading communications technology company, today
announces its preliminary results for its financial year ended 31 December 2006.


Highlights

   - Much improved performance for the second half year.

   - Markets were highly competitive partly as a result of consolidation
     amongst our largest customers.

   - Restructuring actions taken during the year with total annualised cost
     savings of GBP16 million at a total cost of GBP9.1 million.

   - 24 per cent of orders for Communications group in the final quarter of
     2006 came from new product platforms.


Performance Analysis

   - Overall performance reflects continued product transition:
       - Spirent TestCenter(TM) sales grew to GBP20 million (2005: GBP4 million)
       - Existing older platforms, SmartBits and AX, orders declined by GBP27
         million, 15 per cent of total Performance Analysis activity, to GBP48
         million (2005: GBP75 million).
       - All other Broadband products and services grew.

   - Wireless continued to make good overall progress.


Service Assurance

   - Signed our first major contract with TELUS, a leading provider of data,
     IP and wireless solutions in Canada, to provide triple play service
     assurance solutions.


Financial

   - Four acquisitions made for a total initial consideration of GBP39.7
     million.
   - Goodwill impairment of GBP46.8 million in relation to Service Assurance
     and SwissQual.
   - Net funds at the year end of GBP106.1 million with GBP41.9 million returned
     to shareholders to date at an average price of 46.1 pence per share.


Board and management

   - New leadership at both Board level and in key operational positions:
    in-depth business review underway.


Anders Gustafsson, Chief Executive, commented:


"In 2006 Spirent delivered a much improved second half performance benefiting
from growth in new product revenues and the restructuring actions undertaken.


"With new Board leadership and having made key operational appointments we are
now undertaking an in-depth business review, the outcome of which will be
reported before the AGM in May.


"Our performance in 2007 is expected to benefit from the investment in new and
upgraded products and the acquisitions made last year and further progress
beyond that will depend on the outcome of the business review. We are confident
that our new products, led by Spirent TestCenter, will grow revenue and continue
to gain market share although this will be offset by the decreasing revenue from
our older products. With market conditions continuing to be similar to last
year, we consequently expect only a modest growth in Performance Analysis
revenues. In addition, should sterling continue its recent strength relative to
the US dollar, our performance for 2007, particularly in Systems, will be held
back."


Results

The  adjusted  profit and  earnings  per share  measures  have been  restated to
include  share-based  payment  of GBP5.2  million  (2005:  GBP5.1  million)  and
intangible amortisation of GBP1.6 million (2005: nil).

            PRELIMINARY RESULTS FOR THE YEAR ENDED 31 DECEMBER 2006


                              CHAIRMAN'S STATEMENT


At the end of 2006 a number of new directors were appointed to the Board and I
was appointed Chairman. Since that time, the Board as a whole has embarked on an
in-depth review of each of the company's operations.

Since I was not at Spirent during most of 2006 my comments are necessarily
limited. However, it is already clear that the company has a strong base of
technology and customer relationships, reflecting a very talented group of
employees. I would like to express our thanks to them for their contributions
during a year of transition and some market uncertainty.

We also find ourselves with a strong balance sheet, largely due to the sale of
the HellermanTyton business in February. Overall the company has a sound
foundation on which to build for which thanks are due to a number of Board
members who departed during the year.

As you will read below, conditions in some of our markets are somewhat
challenging. However, in reality the outlook for Spirent's financial performance
in 2007 and beyond will be more affected by the actions resulting from the
Board's review than by any foreseeable market developments. The major purpose of
the Board's review is to decide where to focus our resources and how to be the
most efficient and effective competitor in our chosen areas. We expect to
announce the results of the review prior to the Annual General Meeting on
9 May and look forward to communicating with shareholders again at that
time.


We evaluate the performance of Spirent based on revenue and operating profit/
(loss) before the effect of material one-time items and goodwill impairment so
that period on period comparisons are not distorted. Operating profit/(loss) and
return on sales are referred to in the text before material one-time items and
goodwill impairment unless otherwise stated.


                                 GROUP OVERVIEW


Introduction

The year as a whole saw a series of challenges, primarily due to the continuing
variable market conditions resulting from the impact of customer consolidation
and product transition which both depressed sales and margins and was
particularly notable in the first half. As expected at the time of the
announcement of the interim results we delivered a much improved second half
which benefited from the growth in new product revenues and restructuring
actions undertaken. For the full year the adjusted profit before tax was GBP14.3
million compared with a loss before tax of GBP0.2 million in 2005.

Our newly developed and recently launched products and solutions for
next-generation networks continue to grow sales and gain market share and
represented almost 25 per cent of orders for Performance Analysis Broadband in
the final quarter of the year, demonstrating the success of our investment in
product development and the benefit of newly acquired products.

Four acquisitions were completed expanding our breadth of expertise and
solutions into new growth areas such as IP multimedia subsystems ("IMS"), IP
telephony and security test, whilst boosting our offering in other areas such as
wireless.

With new Board leadership and having made key operational appointments we are
now undertaking an in-depth business review, the outcome of which will be
reported before the AGM in May.


Market conditions

The many high profile mergers of the last two years among our customers have
resulted in customers delaying their investment in next-generation networks and
have created highly competitive markets. Indeed, our sales to these latter
customers as a group fell by 8 per cent in the year as a whole, principally in
the first half. As a result overall, many of our markets saw no growth, although
we remain positive for long term growth prospects. We expect our markets will
remain competitive in the current year.



Product transition

A major feature of the year was significant  product  transition.  The growth in
sales  of all  our new and  enhanced  products  was  encouraging,  with  Spirent
TestCenter  sales  reaching GBP20 million  (2005:  GBP4 million),  which was the
Group's  highest  revenue  generating  product in the final  quarter of 2006. As
expected,  orders of our older platforms,  SmartBits and AX, declined sharply by
GBP27  million  being  36  per  cent  year-on-year.  Revenues  from  all  of our
Performance  Analysis  Broadband  products,  apart from SmartBits and AX grew in
2006.

Spending  on product  development  by the  Communications  businesses,  totalled
GBP55.0 million (2005:  GBP56.1 million) of which GBP5.0 million was incurred by
our newly acquired businesses.  Product development was primarily focused on the
new Spirent  TestCenter  platform,  WCDMA  performance test equipment for mobile
handsets and triple play IP service assurance monitoring  solutions,  as well as
in our other faster growing product lines.

Spirent TestCenter was developed to take testing to new levels by consolidating
a host of solutions on a single platform. To date, our new and upgraded products
have been well received by customers, who consistently report enhanced
functionality, improved productivity and reliability. Spirent TestCenter's
performance is very encouraging. It has already been purchased by over 200 cus
tomers worldwide, compared to just 90 when we reported our interim results in
August 2006. These include most of the leading global companies in our industry
and all of our largest customers.

We were pleased with strong performances in our Asia Pacific operations,
especially in Performance Analysis, and Europe, which was boosted by our recent
acquisitions.


Restructuring actions

During the year we continued to manage the balance between the cost base and
maintaining the capability to generate long term growth. Accordingly, we
undertook two major restructuring actions to realign resources and to reduce
operating expenses in our Performance Analysis and Service Assurance divisions,
one announced in June and the other in October, as follows:

   - in June, a total annualised cost reduction of approximately GBP9.0 million
    per year at a one-time cost of GBP3.9 million;

   - in October, a total annualised cost reduction of approximately GBP7.0
    million per year at a one-time cost of GBP5.2 million.

These actions included completion of the outsourcing of all manufacturing except
final assembly and test, continuing investment in our low cost offshore
engineering centre, further divisional management changes and restructuring of
support functions.

Including these actions, we are targeting a long term improvement in operating
margin in Performance Analysis Broadband, with an interim goal to deliver a run
rate of 15 per cent by the end of 2007. The success of Spirent TestCenter as a
single platform should enable the Group to realise significant operating
efficiencies in product development, sales and marketing and other areas within
the division.

The significant restructuring action within Service Assurance is intended to
allow the division to target a break-even position through 2007, whilst funding
the investment in the future of next-generation triple play IP monitoring
solutions.


The Board and staff

Following the Extraordinary General Meeting on 22 December 2006, John Weston,
Andrew Given, Fred D'Alessio, Marcus Beresford and Kurt Hellstrom ceased to be
directors of the Company. We would like to thank them for their collective
service to Spirent over many years.

At the EGM, Edward Bramson, Ian Brindle, Gerard Eastman and Alex Walker were
appointed directors of the Company. Subsequently, Edward Bramson was elected as
Chairman of the Board and appointed as Chairman of the Nomination Committee; Ian
Brindle was appointed Chairman of the Audit Committee, and as a member of the
Remuneration Committee and Nomination Committee; Alex Walker was appointed as
the Senior Independent Non-executive Director and Chairman of the Remuneration
Committee, and as a member of the Audit Committee and Nomination Committee; and
Gerard Eastman was appointed as a member of the Audit, Remuneration and
Nomination Committees.


Outlook

Our performance in 2007 is expected to benefit from the investment in new and
upgraded products and the acquisitions made last year and further progress
beyond that will depend on the outcome of the business review. We are confident
that our new products, led by Spirent TestCenter, will grow revenue and continue
to gain market share although this will be offset by the decreasing revenue from
our older products. With market conditions continuing to be similar to last
year, we consequently expect only a modest growth in Performance Analysis
revenues. In addition, should sterling continue its recent strength relative to
the US dollar, our performance for 2007, particularly in Systems, will be held
back.


Summary

2006 has been a busy and challenging year for Spirent with variability and
unpredictability in our markets. We have worked hard to stay ahead of the
competition and drive the development of our new products and services. We
achieved an improved performance in the second half over the first half year.

We made good progress with our new products and saw growth in a number of key
product areas during 2006. We have secured the first major contract for a
full-scale triple play service assurance solution. We intend to build on this in
2007. In particular the development plans we have for Spirent TestCenter will
deliver increased functionality, scale, ease of use and automation for our
customers.

The sale of the HellermannTyton Division enabled Spirent to achieve a
significantly strengthened balance sheet and to return capital to our
shareholders. Over the coming months the newly constituted Board will be working
to undertake an in-depth business review and will report the outcome before the
AGM in May.



                             GROUP FINANCIAL REVIEW


The Group's financial performance is reported in accordance with International
Financial Reporting Standards ("IFRS") under which the Group's discontinued

The year has been affected by the complexities of implementing major product
transitions combined with continued challenging market conditions in our
communications markets. These market conditions to a large extent were a
consequence of the consolidations of some of our major customers. Revenue
increased by 5 per cent over 2005, excluding the contribution from acquisitions
revenue was flat year-on-year. There were some significant areas of growth,
namely in our voice, security testing, positioning, client services and of
course in sales of our pioneering platform Spirent TestCenter. The growth of
these products was offset by the rapid decline of our two traditional products,
SmartBits and AX, which were down by 36 per cent, as well as the expected drop
in revenue in our Service Assurance division during the second half of the year
as carriers continued to shift spending away from legacy networks. We focused on
the realignment of resources and the reduction in operating expenses across all
divisions and took restructuring actions in both Service Assurance and
Performance Analysis in June and also in October which improved the
profitability in Performance Analysis during the second half year and allowed us
to maintain a near break-even position in Service Assurance.

We are presenting an adjusted earnings measure eliminating the effect of
material one-time items and goodwill impairment. Previously we had adjusted for
intangible amortisation and share-based payment. Comparatives have been restated
to reflect this change.

Adjusted  operating  profit  improved by 30 per cent to GBP8.3 million  compared
with GBP6.4 million in 2005, excluding the effect of exchange, growth was 36 per
cent. This result  includes a significant  reduction in the loss for the Service
Assurance  division  to GBP1.1  million;  (after  share-based  payment of GBP1.2
million,  2005: GBP1.2 million) from a loss of GBP10.8 million reported in 2005.
However,  this was offset by the  decline in  profitability  of the  Performance
Analysis  division down from GBP18.4  million in 2005 to GBP10.5 million in 2006
(after  share-based  payment  of  GBP3.6  million,   2005:  GBP3.6  million  and
intangible  amortisation of GBP1.6 million, 2005: nil), although the performance
improved  in  this  division  in  the  second  half  of  2006.  The  decline  in
profitability  in the  Performance  Analysis  business  was  largely a result of
additional spend on product development and sales and marketing costs associated
with the launch of new product releases.

Return on sales for the Group improved to 3.1 per cent from 2.5 per cent in
2005.

Revenue grew by market in the Asia Pacific region by 7 per cent and in Europe by
27 per cent, a result of the SwissQual acquisition, but it was reduced in North
America year-on-year.


Currency impact

In 2006 the currency  effects were minimal in relation to the income  statement.
The average  sterling to US dollar  exchange rate increased from 1.82 in 2005 to
1.85 in 2006.  Currency  translation  reduced  revenue  by  GBP3.4  million  and
operating  profit by GBP0.4  million  compared with 2005.  With the US dollar to
sterling  rate  rising  to $1.96:  GBP1  this is likely to have a more  material
impact  in  2007.  In  particular  our  Systems  group,   which  is  exposed  to
transactional  currency  risk,  had hedged its exposures and as a result did not
experience the full effect of the weakening of the US dollar in 2006. Should the
current  exchange rate prevail in 2007, this would have a significant  impact on
its profitability.


Cost of sales and operating expenses

Product  development spend is included in cost of sales in the income statement.
2006  was a year  of  major  product  transition  hence  investment  in  product
development remained high, with a total of GBP57.3 million, being 21 per cent of
revenue,  expensed  during the year  (2005:  GBP58.4  million and 23 per cent of
revenue). Of this amount GBP45.5 million (2005: GBP42.1 million) was incurred in
the Performance Analysis division, GBP9.5 million (2005: GBP14.0 million) in the
Service  Assurance  division with the remaining  GBP2.3  million  (2005:  GBP2.3
million)  in the  Systems  group.  The rate of spend  increased  in  Performance
Analysis in 2006 compared with 2005 as we undertook  additional  investment  for
the development of the TestCenter  platform.  Our acquired businesses have added
GBP5.0  million  to  product  development  spend  in 2006.  Product  development
decreased in Service Assurance year-on-year.

Gross profit was higher at 44 per cent of revenue compared with 41 per cent in
2005 as a result of the reduction in product development expense and the
reorganisation of our supply chain activities to increase efficiency as well as
the move to increase outsourcing.

Operating costs,  excluding material one-time items and goodwill  impairment are
41 per cent of sales compared with 39 per cent in 2005.  This is a result of the
additional  sales and marketing effort in respect of new product  launches,  the
significant  costs  of  compliance  with the  Sarbanes-Oxley  Act  2002,  GBP2.6
million,  incurred  as a result  of being a US  listed  company  and  intangible
amortisation of GBP1.6 million (2005: nil).


Material one-time items

Material one-time items include restructuring costs of GBP9.1 million, the costs
related to the EGM requisition in December 2006 of GBP2.0  million,  a credit of
GBP0.6  million  in  relation  to the  release  of  provisions  on prior  period
disposals and curtailment  and settlement  gains of GBP1.7 million in respect of
changes to our defined benefit  pension plan.  Together these total a net GBP8.8
million  cost for the year.  The Group  incurred  a one-time  finance  charge of
GBP8.8  million as the loan notes were repaid early out of the proceeds from the
sale  of the  HellermannTyton  Division,  and we  incurred  fees  to  break  the
associated interest rate swaps.

Restructuring actions took place at the end of June 2006 and in October 2006
affecting both our Communications divisions. These actions were in response to
reductions in demand for legacy products in Service Assurance, and include the
closure of loss making locations and the initiatives identified to help achieve
the divisional margin targets in Performance Analysis. The estimated annualised
cost savings from these actions are GBP16 million in total.

In November 2006 the Company received a notice of requisition from certain
shareholders requesting that the Company convene an Extraordinary General
Meeting to consider the removal of three of its non-executive directors and the
appointment of four proposed new ones. The costs incurred in relation to this
amounted to GBP2.0 million.

During 2006 active and deferred members of the Spirent Staff Pension Plan were
offered the opportunity to leave the Plan and take an enhanced transfer value to
another pension arrangement. Many members accepted this offer resulting in a
benefit to the funding of the Plan under IFRS of GBP1.7 million.


Goodwill impairment

We wrote down goodwill in our Service  Assurance  division by GBP9.5  million at
the interim stage and have taken a further  impairment charge in the second half
of GBP9.6  million.  GBP19.1  million has been charged in total  reflecting  the
delays  in triple  play  roll out and  continued  declines  in legacy  business.
Goodwill in the Service Assurance division has now been fully impaired.

In accordance with IFRS we have also assessed the goodwill carrying value of the
SwissQual business that we acquired in January 2006 where activity levels have
been lower than had been anticipated. This has resulted in a goodwill impairment
charge of GBP27.7 million. Goodwill in SwissQual has been fully impaired. Whilst
we have written down the carrying value of SwissQual, we believe that there are
excellent prospects for the new products in the medium term. However, we have
discounted the projections to reflect the inherent risk in the growth
projections.

Goodwill  impairment  charged in 2005 was GBP37.0  million and was in respect of
the Service Assurance division.


Intangible amortisation

This is the first  year that the Group has  acquired  businesses  under IFRS and
consequently  this is the  first  time  acquired  intangible  assets  have  been
recognised and the associated  amortisation has been charged.  We have made four
acquisitions in 2006 resulting in GBP10.0 million of acquired  intangible assets
being  recognised  on the balance sheet and we have  estimated  that the average
useful life of these  intangibles is 5 years.  These intangible assets represent
current  technology  and customer  relationships  in the main.  Amortisation  of
GBP1.6  million has been  expensed in the income  statement  in 2006 and this is
expected be slightly  higher in 2007 to reflect the full year effect of the 2006
acquisitions.


Share-based payment

The charge for share-based payment for 2006 is GBP5.2 million for our continuing
businesses (2005: GBP5.1 million) based on a fair value model.


Net finance income

In February 2006 we repaid our senior loan notes out of the proceeds of the sale
of the HellermannTyton Division. After funding the UK final salary pension plan
this left us with a significant cash position some of which has been utilised to
pay for acquisitions and commence an on-market share repurchase.

Net finance  income was GBP6.0  million  (excluding  costs  associated  with the
repayment of loan notes)  compared with a net charge of GBP6.6  million in 2005.
Of net income  GBP2.0  million is in respect of the  expected  return on pension
scheme assets less interest on the unwinding of the  liabilities  (2005:  GBP1.1
million  charge) a result of the change to the funding  position of the UK final
salary  pension  plan in February  2006.  Surplus  cash is held on deposit or in
short dated commercial paper and is earning current market rates of interest.


Loss before tax for continuing operations

Reported loss before tax for continuing operations was GBP50.1 million compared
with a loss before tax in 2005 of GBP41.7 million.

Adjusted profit/(loss) before tax is set out below:



 GBP million                                                2006            2005

Tax

The tax charge for 2006 was GBP0.9 million, an effective rate of 6.3 per cent on
the adjusted  profit before tax (2005:  GBP4.0 million  credit).  We continue to
incur a low effective rate due to the carry forward of tax losses.


Discontinued operations

Discontinued operations relate to the HellermannTyton Division which was sold to
Doughty  Hanson & Co Limited on 15 February  2006.  For the period up until sale
the operating result was a profit after share-based payment of  GBP3.0 million.

The profit on the sale before tax was GBP166.1 million and tax of GBP9.2 million
is payable in relation to the sale.  The final  proceeds  from the disposal on a
cash  free/debt  free basis were  GBP296.7  million.  The total  expenses of the
transaction  amounted to GBP10.9  million,  of which GBP6.7 million was incurred
and charged in 2005 and net assets  (excluding debt and cash) sold were GBP128.2
million.  We realised a curtailment  gain on the UK final salary pension fund of
GBP0.5  million.   Unrealised   exchange  gains  of  GBP1.3  million  have  been
transferred from the translation reserve to the profit on sale.



Earnings per share

Basic earnings per share for the Group were 11.75 pence, this includes the
profit on sale of the HellermannTyton Division compared with a loss in 2005 of
2.62 pence. Adjusted earnings per share, being before material one-time items,
goodwill impairment, profit or loss on the disposal of operations and costs
associated with the repayment of loan notes, net of any related tax, was 1.41
pence compared with a loss of 0.22 pence in 2005.


Acquisitions

We acquired  four  businesses  during 2006  paying an initial  consideration  of
GBP39.7  million and deferred  consideration  of GBP3.7 million in the year. All
acquisitions  were  in  the  Performance  Analysis  division.  Further  deferred
consideration payments amounting to approximately GBP6.6 million are expected to
be paid.

On 23 January 2006 we acquired SwissQual Holding AG ("SwissQual") for an initial
consideration of CHF62.5 million ( GBP27.8 million),  paid in cash on completion
with up to a further CHF28.0  million ( GBP12.4  million)  payable  depending on
future revenue growth and on various  technical and financial  milestones  being
achieved. We have paid an additional GBP3.1 million of deferred consideration in
2006 and have accrued for a further  GBP4.5  million of deferred  consideration.
The total estimated  consideration is GBP35.4 million,  GBP4.8 million less than
the maximum  payable.  SwissQual's  solutions  analyse,  measure and improve the
quality of experience for users of wireless applications and services.

On 13 February 2006 we acquired QuadTex Systems,  Inc ("QuadTex") for an initial
consideration of $7.5 million ( GBP4.3 million), paid in cash on completion with
up to a further  $1.5  million ( GBP0.9  million)  payable  depending on certain
technical milestones and the retention of key employees.  We paid GBP0.3 million
of  deferred  consideration  in 2006.  QuadTex is a provider of  innovative  and
leading test tools for internet protocol multimedia  subsystem ("IMS") and voice
over IP ("VoIP") testing.

On 10 July 2006 we acquired Scientific Software  Engineering,  Inc. ("SSE"), the
US based developer of the Landslide product, a leading software based system for
testing  the  performance  and  functionality  of 2.5  and 3G  wireless  network
infrastructure for an initial  consideration of $10.0 million ( GBP5.5 million),
paid in cash on completion  with up to a further $6.0 million ( GBP3.3  million)
payable  depending on the satisfaction of certain  technical  milestones and the
retention  of key  employees  in  2007.  We  paid  GBP0.3  million  of  deferred
consideration in 2006.

On 10  August  2006  we  acquired  the  business  of  Imperfect  Networks,  Inc.
("Imperfect Networks"),  a US based developer of security testing solutions. The
acquisition  enables Spirent to deliver enhanced  security testing  solutions to
its customers  across a number of markets.  The initial  consideration  was $4.0
million ( GBP2.1 million), paid in cash on completion, with up to a further $4.0
million ( GBP2.2  million)  payable  depending  on the  satisfaction  of certain
technical milestones and revenues to be achieved in 2007.


Financing and cash flow

At 1 January 2006 cash and cash equivalents were GBP49.2 million and borrowings,
which comprised  mainly of GBP70.9 million of senior loan notes attracting a 9.1
per cent rate of interest, were GBP84.8 million. The sale of the HellermannTyton
Division enabled the Group to realise a significant  amount of cash repaying the
loan notes, extinguishing all other debt, funding the GBP47.0 million deficit in
the UK final salary  pension  fund and  commencing  an on-market  share buy back
programme.  We ended the year with cash and cash equivalents of GBP97.6 million,
a  significant  strengthening  of the balance  sheet from the prior year end. In
addition GBP8.5 million of cash is held on deposit in a blocked trust account as
required by the capital restructuring discussed below.

Operating cash flow was  representative  of the tough market  conditions and the
additional costs required to undertake such significant product transition.  Net
cash outflow from  continuing  operations  before tax was GBP40.8 million (2005:
GBP1.1 million outflow). This outflow includes a GBP47.0 million contribution to
fund the UK final salary pension plan and other one-time costs.

Adjusted operating cash flow before tax is set out below:




 GBP million                                                  2006          2005

During 2006 the Group absorbed GBP10.6 million of working capital much of which
was in relation to receivables and a consequence of the higher activity levels
experienced during the latter part of the year.

Reported operating cash outflow for the continuing Group after tax was GBP42.4
million (2005: GBP1.8 million outflow) and discontinued operations used GBP0.6
million of operating cash in the period up to disposal (2005: GBP31.2 million
inflow). Tax payments in 2006 amounted to GBP2.3 million compared with GBP4.6
million in 2005 (including discontinued operations). In the first quarter of
2007 we will settle tax obligations on the sale of the HellermannTyton Division
of approximately GBP6.7 million.

Capital  expenditure was GBP12.6  million  compared with GBP14.8 million in 2005
for the continuing  Group.  The  depreciation  charge was GBP11.8 million (2005:
GBP11.4 million).

We spent GBP44.4  million on the  acquisition of businesses in 2006 and received
net cash of  GBP278.2  million  from the sale of the  HellermannTyton  Division.
Deferred  consideration  payments on  acquisitions  amounting  to  approximately
GBP6.6 million are expected to be paid.

As  previously  mentioned the senior loan notes were repaid in February 2006 and
this left the Group debt free. On the early repayment of loan notes a make whole
amount  was due of  GBP7.2  million  and we  incurred  break  fees on the  early
termination  of  interest  rate  swaps of GBP2.3  million.  Net  finance  income
received in 2006 was GBP4.1 million  compared with a net finance cost in 2005 of
GBP6.5 million.


Pension fund

The surplus in the UK defined  benefit  pension  plans at 31  December  2006 was
GBP2.4  million  (2005:  net  deficit  GBP50.8  million),  having been funded in
February  2006 by way of a special  contribution  of  GBP47.0  million  from the
proceeds of the disposal of the HellermannTyton  Division. During 2006 the plans
have  benefited from rising equity markets but have also benefited from an offer
made to active and deferred  members giving them the opportunity to leave the UK
final salary pension plan and take an enhanced transfer value to another pension
arrangement.  Many  members  accepted  this offer  resulting in a benefit to the
funding of the plan under IFRS of GBP1.7  million and a  reduction  in the total
liabilities  of the plan of  GBP21.8  million.  The value of the  surplus  at 31
December 2006 has been calculated using the latest mortality assumptions, and as
such this has adversely affected the position.

The triennial actuarial valuations of the plans at 1 April 2006 are currently
being finalised.

A defined  benefit  pension  plan  deficit is reported  of GBP1.4  million at 31
December 2006 in respect of the acquired scheme in SwissQual and the unfunded UK
plan.


Capital structure, on-market share repurchase programme and dividend

During 2006, and following on from the cancellation of the share premium account
and capital  redemption reserve (the  "Cancellation")  which took place in 2004,
the Company was able to release  non-distributable  special reserves formed as a
result of the  Cancellation  by  placing  funds in a blocked  trust  account  in
accordance  with  the  undertakings  made  to  the  Court  at  the  date  of the
Cancellation.  At 31 December  2006 cash held in the blocked  trust  account was
GBP8.5 million. The Company currently has reserves of GBP194.1 million which are
capable of being  distributed to shareholders  through dividend or through share
buy back.

We commenced an on-market share repurchase programme in May 2006 which had been
announced to shareholders together with the proposed disposal of HellermannTyton
in December 2005. To date we have returned GBP41.9 million, being 90.3 million
shares, to shareholders at an average price of 46.1 pence per share. There is a
further GBP8 million to be returned of the originally announced GBP50 million
programme. Purchases are expected to be completed during 2007. It was also
announced in October that the Company proposed to seek authority for a further
return of GBP50 million to shareholders. This will be considered further as part
of the in-depth business review currently underway.

Dividend policy is kept under review by the Board, however no dividend is being
declared in respect of 2006.


Review of US listing and SEC registration

As  announced  in October  2006 the  Company has been  carrying  out a review to
explore a process by which it can  de-list  its shares  and  de-register  in the
United States.  The US listing has become  significantly more costly and onerous
in  recent  years,  not  least  due to  the  imposition  of  the  Sarbanes-Oxley
regulations,  which have cost the Company  approximately  GBP2.6  million during
2006.

If the proposed SEC rule change announced in December 2006 is passed without
significant amendment it is expected that the Company will be able to seek a
de-registration as a result of its extremely low trading volumes in the US.

A further update on progress towards de-listing and de-registration will be made
as and when appropriate.

Performance Analysis

Results for Spirent's Performance Analysis division were marked by significant
growth for a number of its products and solutions, including the pioneering
Spirent TestCenter platform, and an appreciably improved second half due to
early intervention efforts to increase profitability. However, the division's
overall performance was dampened by market variability, intense competition,
delays in technology upgrades and a significant decline in revenue for two
established products.

In 2006, Performance Analysis introduced many new releases and established a
solid foundation for future profitable growth within the segments of 3G
wireless, IMS and VoIP. Several products had noteworthy results, including:

- Spirent TestCenter, which was the Group's highest revenue generating
product in the fourth quarter;

- Spirent Protocol Tester, which received two industry recognition
awards - one of the 10 "Best In Test" products for 2006 by Test & Measurement
World and Product of the Year by Internet Telephony;

- Our security test solutions Avalanche and ThreatEx (the result of the
acquisition of Imperfect Networks);

- Abacus, a leading VoIP testing solution;

- Launch of the new Diversity product (acquired as a result of the
SwissQual acquisition), with subsequent key customer wins; and

- The first test demonstration of a Galileo global positioning system.

In 2006, revenue for this division of GBP192.2 million (2005:  GBP178.8 million)
was up 7 per cent whilst  operating  profit  decreased by 43 per cent to GBP10.5
million (2005:  GBP18.4 million) principally weighed towards the first half. The
decline was largely due to additional spend on product development and sales and
marketing costs associated with the launch of new product releases.  To mitigate
the weak first half  restructuring  actions  were taken at the end of the second
quarter together with a greater focus on improving profitability.  These actions
resulted in a  significantly  improved  second half  operating  profit of GBP7.3
million  and a return  on sales of 7.5 per cent  versus a first  half of  GBP3.2
million, and a return on sales of 3.4 per cent.

Spirent's top 20 customers typically represent an estimated 36 per cent of
Performance Analysis revenues. No one customer represented more than 10 per cent
of the total divisional revenues. On a geographic basis there was growth in
Europe driven by Performance Analysis Positioning and SwissQual. Activity in the
Asia Pacific region grew, building on strong growth particularly in China and
India.

Throughout 2006, market conditions continued to be variable and unpredictable in
Performance Analysis Broadband ("Broadband"). While we saw an increase in
spending among some customers in the second half, when combined with customers'
reduced spending in the first half, Broadband experienced a flat year overall.
This was driven by a reduction in the total available market due to
consolidation activity among larger customers, lower spending from our largest
customer, Cisco, and strong competition in the routing, switching, access, and
L4-7 spaces, and in the VoIP and IMS markets. The tougher competitive
environment resulted in pressure on pricing, particularly at our larger
accounts.

Despite unpredictable market conditions, Broadband gained position with leading
customers and strengthened its position in the growing security market with the
acquisition of Imperfect Networks (ThreatEx).

The majority of product development investment for Broadband went to launching
new products and to positioning Spirent for the long term. Spirent TestCenter
continues to make significant gains in the marketplace, including:

- More than half of Spirent TestCenter customers are repeat buyers;

- A significant number of customer wins are at incumbent accounts of the
competition;

- Our top 20 Broadband customers are using Spirent TestCenter; and

- More than 180 customers are now using the new platform.

Spirent's Broadband customers are interested in driving significant competitive
advantage through faster time to market for new services and products, deploying
new services to tap into new revenue streams and seeking highly integrated
solutions to reduce their footprint. They understand that complex testing cannot
be outsourced and that their resources for implementing complex testing are
limited. Development plans for Spirent TestCenter will deliver increased
functionality, scale, ease of use and automation so that our customers can
continue to improve time to test, reduce the cost of testing and achieve a
faster time to revenue for their new products and services. Spirent TestCenter
architecture is significantly ahead of the competition and is designed to
integrate new technologies moving forward to protect customers' investments.

Results for Performance Analysis Wireless ("Wireless") mirrored that of
Broadband - a combination of key market successes countered by market and
product challenges. Spirent's overall CDMA business was down due to a lull in
the air interface evolution by network operators which led to the lack of a new
technology catalyst for testing. In the WCDMA market, our gains in selling into
GSM and WCDMA-based A-GPS mobile device test applications were offset by
declines in the RF test business.

In the Mobile Device Test segment, where we hold a significant market share, we
had a strong year for Location Based Services test in both the CDMA and WCDMA
markets. Spirent's Location Test Systems turned in a record-breaking year,
driven by additional regulatory requirements for handsets and growth in the
deployment of commercial Location Based Services. More than
60 per cent of Wireless R&D is focused on the WCDMA applications market, and
Spirent continues to invest in its core network emulator platform to improve
feature capability. Wireless also saw some modest continued growth in the
simulator market for faders, driven by the evolution of Mobile Input-Mobile
Output technology, a key element of WiMax deployment. At the end of the year,
Spirent saw activity in testing for Mobile TV begin to ramp. This exciting
industry promises to be a key area of focus for Spirent as mobile network
operators deploy multi-media services in 2007.

Performance Analysis Positioning ("Positioning") saw its third year of
double-digit growth. Of note, Positioning launched the World's first commercial
Galileo simulator and secured key contracts for official Galileo program
business. Galileo is expected to be a significant source of revenue in the
future.

Spirent entered into the Subscriber Experience Management ("SEM") market segment
as a result of its acquisition of SwissQual. Here, Spirent experienced a
significant impact from widespread industry consolidation, reducing demand
markedly. In addition, there were substantial delays in purchasing decisions
compared to previous years. Competition is intense as well and drove increased
pressure on pricing; whilst several competitors merged to improve their market
position. Despite these conditions, Spirent added an estimated 30 new SEM
customers during the year. It launched a new product, Diversity, which was well
received by the market and gained traction with leading mobile network
operators.



Service Assurance

In 2006, Spirent's Service Assurance division stabilised its performance amid
significant market consolidation, secured important contracts for its triple
play service assurance and field test solutions and delivered a break-even
result before share-based payment of GBP1.2 million, marking a significant
improvement over its performance in 2005.

Delays in customer decisions and spending on new solutions continued throughout
the year and competition remains strong as service assurance players vie for
fewer customers and retention of incumbent positions due to market
consolidation. Carriers continue to shift spending away from legacy networks as
they deploy triple play offerings, however the current limited triple play
subscriber base is restricting the service assurance market.

Overall  revenues were slightly  higher for Service  Assurance  compared to last
year, due to the recognition of revenue from one-time projects for remote packet
access  testing in the first  half of 2006.  Operating  loss was GBP1.1  million
compared  with  a  loss  of  GBP10.8   million  in  2005.  The   improvement  in
profitability is due to increased  revenue and margin,  coupled with the benefit
of  restructuring  actions that took place in the second quarter.  These actions
allowed the division to target a break-even  position before share-based payment
for the year.

The revenue profile has remained comparable with the prior year, with the
majority of revenue coming from US service providers. Revenue from DSL equipment
(20 per cent of total revenue) was higher in 2006 due to increased customer
demand. Leased line revenue for service assurance products (50 per cent of
total) was down on 2005 as anticipated as customers continued to move spending
away from legacy service assurance solutions.

Service Assurance has begun to see the results of its investment in
next-generation services. It secured a strategic contract with TELUS, a leading
provider of data, IP and wireless solutions in Canada. The contract represents
the first award for a full-scale triple play service assurance solution. It also
demonstrates that the triple play market is growing and that carriers understand
service assurance solutions are needed before scaling services. In addition, the
Service Assurance division's new handheld field test device, Tech-X, was
approved and deployed at major North American customers.

Service Assurance is focused on providing the right tools for service providers
to scale triple play services and ensure consumers' Quality of Experience
("QoE"). Its portfolio includes software and hardware based centralised test and
diagnostic solutions as well as handheld field test devices. The Tech-X is the
first all-in-one field test solution that combines testing of copper, xDSL and
triple play services enabling field technicians to access the power of the
central test and monitoring systems in the field. Spirent's triple play service
assurance solutions allow service providers to get it right the first time,
scale the service while managing operating costs, and dispatch to fix not to
find problems. From the lab to the live network, Spirent is the only company
that offers triple play solutions throughout the entire technology lifecycle.

The Service Assurance division will continue to seek opportunities to realise
the potential of its existing baseline business while focusing its investments
on expanding its position in the triple play market. However, continuing delays
in the roll out of triple play service assurance solutions by our customers is
likely to impact the timing of deployment of our new centralised test products.
In the short term we expect that revenue from legacy products will decline
faster than the ramp up of revenues from our triple play solutions.

The Systems group comprises PG Drives Technology, a leading supplier of control
systems for electrically powered medical and industrial vehicles. Revenue was
down 5 per cent and operating profit up 9 per cent, respectively. Return on
sales increased to 13.1 per cent compared with 11.4 per cent in 2005.

During  2006  we saw  continued  strong  revenues  from  the  VR2,  a low  cost,
mainstream wheelchair control system that we launched in second half of 2005, as
well as growing market recognition for the R-net, our highly sophisticated rehab
wheelchair  system.  These new  products,  together with our  established  ones,
enabled us to increase customer  penetration in both the mobility and industrial
vehicles  markets  during the year.  This was  achieved  in spite of  continuing
constraints in US government healthcare funding for powered wheelchairs. We also
moved  more of our  production  to  China  to  reduce  the  logistical  costs of
supporting  our  activities  in the Asia Pacific  region.  At the end of 2006 we
launched two new systems, X25/30 and Sigmadrive,  targeted at heavier industrial
vehicles.  These new  products  will  spearhead  our entry  into new  industrial
markets.


Non-segmental costs

Non-segmental  costs,  being those which are not  directly  attributable  to the
operating  segments,  were GBP5.8 million  compared with GBP5.5 million in 2005.
These  costs  relate to the costs of our Board and costs in relation to our dual
listing, including much of the costs of the Sarbanes-Oxley Act of 2002.
