These are Porvair's first reported results under IFRS (International Financial Reporting Standards) and prior period amounts have been restated to reflect the new Standards. Sales revenues were up 7% at £23.0m (2005 £21.6m). Earnings per share were up 36% to 1.5p (2005: 1.1p). Demonstrable progress has again been made with new products, notably in gasification filters, fuel cell bipolar plates and bioscience devices. The Board has declared an unchanged interim dividend of 1.0p (2005: 1.0p). Strategy - focus on specialist filtration and environmental technologies Porvair makes specialist filters for growing market segments where product life cycles are long and technical specifications challenging. The engineering expertise necessary to design this sort of bespoke filter can be spread across many of the market segments served. Porvair continues to invest heavily in R&D projects that offer significant sustainable growth potential. These are often environmental projects and include: • Filters to clean gasified coal and biomass • Substrates to reduce diesel exhaust emissions • Fuel cell components • Bioscience filtration and separation devices • Combustion plates that improve efficiency and reduce emissions. Operating Review The first half of 2006 was encouraging for the Microfiltration division, which includes the Porvair Filtration Group and Porvair Sciences. Sales grew 7% to £12.8m (2005: £11.9m). Operating profits before exceptional items grew 38% to £2.1m (2005: £1.5m; £2.2m including an exceptional gain of £0.7m). Growth during the first half of 2006 was broadly spread and was led by the aerospace, high purity liquids, industrial processes and bioscience markets. Two substantial, long term contracts with civil aviation customers were won during the period which will support our sales into this segment over the next few years. We continue to build our position in the market for gasification filters with improved awareness of our capabilities and growth in sales. This segment is a key growth opportunity for Porvair. These filters are typically used in clean coal and biomass applications and demand for our products and engineering expertise has been strong. New and repeat orders have been received during the period. In April we signed a joint development agreement with a major oil company and leading provider of gasification technology, under which we will design and test the next generation of filters for hot gas. This agreement follows the long-term, successful operation of Porvair filters in a commercial coal gasification environment and confirms our growing reputation and track record in this market segment. Part of the Porvair Filtration Group R&D investment in recent years has been spent developing porous plastics capabilities by physically and chemically altering the surface properties of the plastics to broaden their range of applications. These proprietary capabilities are opening up promising opportunities in medical diagnostics and pharmaceutical research. Sales into this segment were up 40% compared with the first half of 2005 helped in part by production and sales of our first pharmaceutically approved filtration component. Several bioscience separation devices have reached the prototype stage and one product launch is expected in the second half of the year. Our US based Metals Filtration division specialises in the filtration of hot metals, and in particular aluminium. The first half of 2006 has been challenging as input costs rose faster than selling prices in the early part of the year. Customer contracts in this operation do not generally allow for quick changes in price. Margins in the first half of 2006 have therefore been compressed. Management actions to reduce costs and pass on price rises have been underway for some months and began to show results towards the end of the period. Sales in the six months to 31 May 2006 were up 4% at £9.7m compared with the prior year. The business had break even operating performance, with profits in the second quarter giving encouragement for the second half of the year. Our plant in North Carolina continues to run efficiently; we continue to work on our cost base; and we see opportunities for sales growth in the second half of the year. Porvair Advanced Materials (PAM) is a development company working on two new materials for a range of applications including fuel cells, clean diesel exhaust systems and low emission combustion plates. These are key growth opportunities for Porvair. As previously outlined, these projects are complex and unforeseen challenges are to be expected. Consequently success is all the more enjoyable and it is a pleasure to report a 58% sales increase for the year to date from products already sold commercially in the combustion and structural market segments. Production scale-up work on our diesel exhaust substrate continues. This market has been slower to develop than expected due to European legislative delays but we are pleased with technical progress made and have high expectations for this application. Our principal customer's test results continue to be positive and we have refined our product specifications and improved process capabilities. Small scale commercial orders have been received for heavy duty diesel retrofit opportunities in Europe. The highlight of the year so far in PAM has been a successful extended trial of our latest generation of low cost bipolar plates for fuel cells. This is a lengthy development project and we were particularly pleased to receive our first order for the new generation of plates in May 2006. As has been previously reported, when compared with plates produced in 2003 the latest moulded products offer a better technical performance at almost one tenth of the price. This first order will be manufactured using production methods and quality standards suitable for low cost mass production. We expect to move from product development to preliminary sales, albeit only for prototype fuel cells, in the second half of the year. Our proprietary carbon material can be readily adapted to a variety of Proton Exchange Membrane (PEM) fuel cell designs and we will continue with this work in the months ahead. Profit for the period The profit for the period attributable to shareholders increased by 54% to £599,000 (2005: £390,000). The Group benefited from 100% of the earnings of the Porvair Filtration Group in the period having acquired the minority interest in November 2005. Profit for the period from the core specialist filtration businesses, Microfiltration and Metals Filtration, was £1.36m (2005: £1.15m) and the loss arising from the investment in the Advanced Materials division was £758,000 (2005: £757,000). Cash flow Cash generated from continuing operations was £617,000 (2005: £1.87m including £711,000 from exceptional items). Net interest paid was £377,000 (2005: £177,000), higher than the prior year as a result of rising US interest rates, additional borrowings drawn down in November 2005 to finance the minority acquisition and the prior year benefiting from of a one off interest credit on collection of an old debt. £773,000 (2005: £482,000) was paid in tax. The Group's tax paid in the first half represents broadly half the tax due on the prior year's profits. The increase in the period reflects the increase in UK generated profits in 2005 compared with 2004. £929,000 (2005: £648,000) was paid out in the period from provisions relating the businesses disposed in 2003, including the final £550,000 installment of the £1.5m payment to the pension scheme agreed at the time of the business disposals. Interest cover was three times (2005: four times). Net borrowings rose by £1.2m to £9.7m compared with 30 November 2005. Outlook 2006 is progressing satisfactorily. Current trading is healthy and order levels, particularly in Microfiltration, are robust. The Metals Filtration business has responded to the challenging conditions in the early part of the year and is currently trading well. The key development opportunities are making good progress and all parts of the business have growth opportunities for the second half of the year.

Basis of preparation For all periods up to and including the year to 30 November 2005, Porvair plc prepared its financial statements in accordance with UK Generally Accepted Accounting Principles ('UK GAAP'). From 1 December 2005, Porvair plc is required to prepare consolidated financial statements in accordance with International Financial Reporting Standards ('IFRS') as endorsed by the European Union ('EU'). The first results reported under IFRS are for the six months to 31 May 2006 and the comparative information is also presented in accordance with IFRS. On 19 May 2006, the Group reported on the impact of changing from UK GAAP to IFRS on its results for the six months to 31 May 2005 and the year to 30 November 2005 and included a statement of the most significant IFRS accounting policies adopted. Details of the changes are provided in the document 'Transition to International Financial Reporting Standards (IFRS)' that is available on the Group's website ( www.porvair.com) or from the Company Secretary. The financial information has been prepared in accordance with all IFRS and International Financial Reporting Interpretations Committee ('IFRIC') interpretations that had been published by 31 May 2006 and apply to accounting periods beginning on or after 1 December 2005. The standards used are those endorsed by the EU together with those standards and interpretations that have been issued by the International Accounting Standards Board ('IASB') but had not been endorsed by the EU by 31 May 2006. The 2005 comparative information, as permitted by the exemption in IFRS1, has not been prepared in accordance with IAS 32 'Financial Instruments: Disclosure and presentation' and IAS 39 'Financial Instruments: Recognition and Measurement'. Further standards and interpretations may be issued that will be applicable for the financial years beginning on or after 1 December 2005 or that are applicable to later accounting periods but may be adopted early. Therefore, the Group's first full IFRS financial statements to 30 November 2006 may be prepared in accordance with some different accounting policies from the financial information presented here. Furthermore, due to the number of new and revised Standards included within the body of Standards that comprise IFRS, there is not yet a significant body of established practice on which to draw in forming opinions regarding interpretation and application. Accordingly, practice continues to evolve. At this early stage therefore, the full financial effect of reporting under IFRS as it will be applied and reported on in the Group's first IFRS financial statements cannot be determined with certainty and may be subject to change. 2. Prior year adjustment Porvair has elected to adopt IAS 32 Financial Instruments: Disclosure and Presentation and IAS 39 Financial Instruments: Recognition and Measurement from 1 December 2005 with no restatement of comparative information. Consequently, the relevant comparative financial information for the six months ended 31 May 2005 and the year ended 30 November 2005 does not reflect the impact of these standards, but includes financial instruments accounted for on a UK GAAP basis. A prior year charge of £66,000 is shown in changes in equity for the six months ended 31 May 2006 to reflect the change of accounting policy in the period. 3.

Independent review report to Porvair plc Introduction We have been instructed by the Company to review the financial information for the six months ended 31 May 2006 which comprises the Group balance sheet as at 30 June 2005 and the related Group profit and loss account, Group cash flow statement, Consolidated statement of recognised income and expenditure and the Consolidated statement of changes in shareholders' equity for the six months then ended and related notes. We have read the other information contained in the interim report and considered whether it contains any apparent misstatements or material inconsistencies with the financial information. Directors' responsibilities The interim report, including the financial information contained therein, is the responsibility of, and has been approved by the directors. The directors are responsible for preparing the interim report in accordance with the Listing Rules of the Financial Services Authority. As disclosed in note 1, the next annual financial statements of the Group will be prepared in accordance with International Financial Reporting Standards as adopted by the European Union. This interim report has been prepared in accordance with the basis set out in the note 1. The accounting policies are consistent with those that the directors intend to use in the next annual financial statements. As explained in note1, there is, however, a possibility that the Directors may determine that some changes are necessary when preparing the full annual financial statements for the first time in accordance with International Financial Reporting Standards as adopted by the European Union. The IFRS standards and IFRIC interpretations that will be applicable and adopted by the European Union at 30 November 2006 are not known with certainty at the time of preparing this interim financial information. Review work performed We conducted our review in accordance with guidance contained in Bulletin 1999/4 issued by the Auditing Practices Board for use in the United Kingdom. A review consists principally of making enquiries of Group management and applying analytical procedures to the financial information and underlying financial data and, based thereon, assessing whether the disclosed accounting policies have been applied. A review excludes audit procedures such as tests of controls and verification of assets, liabilities and transactions. It is substantially less in scope than an audit and therefore provides a lower level of assurance. Accordingly we do not express an audit opinion on the financial information. This report, including the conclusion, has been prepared for and only for the company for the purpose of the Listing Rules of the Financial Services Authority and for no other purpose. We do not, in producing this report, accept or assume responsibility for any other purpose or to any other person to whom this report is shown or into whose hands it may come save where expressly agreed by our prior consent in writing. Independent review report to Porvair plc (continued) Review conclusion On the basis of our review we are not aware of any material modifications that should be made to the financial information as presented for the six months ended 31 May 2006. PricewaterhouseCoopers LLP Chartered Accountants Cambridge 3 July 2006 Notes: (a) The maintenance and integrity of the Porvair plc web site is the responsibility of the directors; the work carried out by the auditors does not involve consideration of these matters and, accordingly, the auditors accept no responsibility for any changes that may have occurred to the interim report since it was initially presented on the web site.
