Chief Executive's review Overview Porvair has delivered profits growth and further progress in its key development projects in the six months to 31 May 2007. Sales revenue was £22.9m (2006: £23.0m). In constant currencies sales growth was 5% - the weaker US dollar reduced reported sales. Profit before tax was held back by a £0.25m restructuring charge in Metals Filtration but nonetheless rose 64% to £1.5m (2006: £0.9m). Earnings per share were up 66% to 2.5p (2006: 1.5p). Demonstrable progress has again been made with new products: customer deliveries of an entirely new metals filter started; further orders were received for gasification filters; and the Group's inerting filter secured a second major account win. Omnifilter Inc was acquired to offer the UK based Microfiltration division a platform for growth in the US. The Board has declared an unchanged interim dividend of 1.0p (2006: 1.0p). Strategy - focus on specialist filtration and environmental technologies Porvair looks for opportunities to grow its business where technically challenging applications and design expertise can give us a competitive edge. We seek to acquire businesses that complement our existing skills and invest in projects that offer the prospect of attractive growth. We see significant potential in environmental technologies and our current development portfolio includes: • filters to clean gasified coal and biomass; • substrates to reduce diesel exhaust emissions; • fuel cell components; • bioscience components and devices; • plates to improve gas combustion efficiency; • high-value metal alloys filters to reduce process waste; • aviation air-cleaning filters for fuel tank inerting. Our development projects are funded from core business cash flows, and for some years this has had a considerable impact on cash flow and Group profits. The scale of this investment is reducing as projects come to fruition across the Group. Operating Review Microfiltration The UK based Microfiltration division continued its growth. Revenue for the period was up 4% to £13.3m (2006: £12.8m) despite a weaker US dollar affecting the reported US dollar sales revenue. The strong aviation demand of 2006 continued in 2007 with revenue up 22%, reflecting a robust underlying business and growth in engineered components. This growth has helped offset a decline in the export of laboratory filtration plates, with the weaker US dollar giving rise to price pressure in the US. Operating profit of the division was £2.3m (2006: £2.5m). The weakness of the US dollar accounts for the lower operating profit, principally as a result of translating US dollar revenue at a lower rate. Several of the Group's key development projects are managed in the Microfiltration division: • Previous announcements have described a complex filter design that is to be used in fuel tank inerting systems for commercial aircraft. Following extensive trials this product received qualification from Boeing in the first half of 2007. We had expected production of this unit to start immediately after qualification but delays with other suppliers to this project have postponed this until later in the year. In February, we signed a supply agreement with Parker Hannifin for a similar filter to be used in the inerting systems on the Airbus fleet. This was exciting news and means that when production starts the sales opportunity is greater. • A large order for gasification filters was received in May for delivery early in 2008. The demand for engineering design work and test trials for gasification filters has continued to grow in the period. We expect this work to turn into substantial orders in the years ahead. • Our initiatives in BioScience continue to progress, primarily as a result of the successful development of chemical surface treatment of our porous plastic materials. We are working with a number of industrial partners on the commercialisation of this technology. Examples that may generate revenues in the next 12 months include Point of Care diagnostics components and a new range of devices for solid phase extraction use. Looking further ahead: work at Brighton University has shown our BioVyonTM Polyethylene to be a promising substrate for cell growth; and our materials have been incorporated into a device now in clinical trials for the treatment of Sepsis. Forecast growth from aviation and other development projects means that we expect Microfiltrex - part of the Porvair Filtration Group - to outgrow its capacity in the next 12 months, requiring a move to larger premises in 2008. In January 2007, the Group acquired OmniFilter ('Omni') and has successfully integrated it into the Microfiltration division. Omni is a manufacturer of filters and filtration media complementary to those already made in the Group. It is based in Virginia and offers the Microfiltration division a base from which to accelerate its growth in the US. It has traded well in its first five months and we welcome Omni's staff to the Porvair Group. Metals Filtration Sales in our US based Metals Filtration division were £9.4m (2006: £9.7m). In US dollar terms revenues grew 8% to $18.6m (2006: $17.2m). This was driven by growth in much of our domestic US business but also by improving export demand. In contrast with the UK Microfiltration business, the US Metals Filtration business's export sales benefit from a weaker US dollar making its products more competitive. In general it has been the more specialised parts of the Metals Filtration division that have grown the most. Engineered Ceramics, a subsidiary based in Illinois, continues to trade well by concentrating on bespoke refractory products for the investment casting and transportation wheel markets. Demand for filters and consumables for specialist alloy manufacturers is strong, as is demand for both iron and aluminium foundry filters. Operating margins in the Metals Filtration division started to benefit from a restructuring of its cost base in early 2007. The reported operating profit of £334,000 (2006: £34,000 loss) comprises an underlying operating profit of £583,000 and a restructuring charge of £249,000. In April an important milestone was reached in one of the Group's key development projects as customer deliveries began of an entirely new type of specialist metals filter. The technology for these products was originally developed by Sandia National Laboratories in the US. Along with the necessary intellectual property arrangements a multi-year customer contract was signed. Production scale-up will take place through 2007. At full capacity, which we expect to reach in 2008, this product line should generate up to $5m in sales revenue and will underpin the improving results in the Metals Filtration division. Porvair Advanced Materials Manufacture of the latest generation of bipolar plates for fuel cells continued throughout the period in Porvair Advanced Materials ('PAM'), where losses reduced to £528,000 (2006: £779,000). The Group has developed two materials in PAM: carbon composites for fuel cell components and metallic foam for a range of applications, principally combustion plates and diesel exhaust components. While there is always more work to be done, the development cycle for the fuel cell components is coming to a close. Our materials have been demonstrated to meet stringent standards and our manufacturing capability is good at current levels of volume. We are discussing next steps with our principal customer, United Technologies, as we wait for the market for PEM fuel cells to develop. Porvair's unique metallic foams have a range of applications, of which combustion plates and diesel emission filters are currently the two most active. We have exhaust emission development projects covering stationary diesel engines, diesel cars and smaller engines. Field trials and design developments will continue throughout 2007. Profit for the period The profit for the period attributable to shareholders increased by 70% to £1.0m (2006: £0.6m). Profit for the period from the core specialist filtration businesses, Microfiltration, Metals Filtration and other unallocated costs, increased by 12% to £1.55m (2006: £1.38m) and the loss arising from the investment in the Advanced Materials division reduced by 32% to £528,000 (2006: £779,000). Cash flow Cash generated from continuing operations was £2.2m (2006: £0.3m outflow). Net interest paid was £309,000 (2006: £377,000), where higher interest paid as a result of higher interest rates has been offset by a lower finance cost relating to the Group's defined benefit pension scheme. £301,000 (2006: £773,000) was paid in tax. The Group benefited from a £198,000 rebate of tax in the period relating to prior periods. £1.1m was paid to acquire Omni and £658,000 (2006: £439,000) was paid to acquire intangible and tangible fixed assets. The final expected receipt in relation to the 2003 disposals of £200,000 (2006: £500,000) was received in the period. Interest cover was 7.6 times (2006: 3.1 times). Net borrowings reduced to £8.8m (2006: £9.7m) compared with the prior period. Outlook Porvair has delivered profits growth and further progress in key developmental projects. The year is progressing well and in line with management's expectations. Customer demand, particularly for aviation products and US exports, is growing. We are pleased that the restructuring in the Metals Filtration division is improving results which will be supported further by increasing sales of our new filter for high specification metal alloys. The Group looks forward with confidence.

The accounting policies remain as published in the financial statements for the year ended 30 November 2006 and are expected to be applied for the year ending 30 November 2007, in accordance with International Financial Reporting Standards (IFRS), as adopted in the EU, and International Financial Reporting Interpretation Council (IFRIC) interpretations issued and effective at the time of their preparation. There has been no change to these accounting policies as a result of new standards, amendments and interpretations to existing standards that have been published and which are mandatory from 1 December 2006. These interim financial statements have been prepared on a going concern basis under the historical cost convention, as modified by the revaluation of certain current assets, financial assets and financial liabilities held for trading and derivative contracts, which are held at fair value. The preparation of financial statements in conformity with generally accepted accounting principles requires the use of estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Although these estimates are based on management's best knowledge of the amount, event or actions, actual results may ultimately differ from those estimates. These interim financial statements and the comparative figures for the year ended 30 November 2006 do not constitute full accounts within the meaning of the Companies Act 1985. Full accounts for the year ended 30 November 2006, which include an unqualified audit report and no statements under sections 237(2) or (3) of the Companies Act 1985, have been delivered to the Registrar of Companies. This report is being sent to shareholders and will also be available at Porvair plc's registered office at Brampton House, 50 Bergen Way, King's Lynn, PE30 2JG and on the Company's website www.porvair.com. 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 2007 which comprises the Consolidated balance sheet as at 31 May 2007 and the related Consolidated income statement, Consolidated statement of recognised income and expense and Consolidated cash flow statement 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 Listing Rules of the Financial Services Authority require that the accounting policies and presentation applied to the interim figures should be consistent with those applied in preparing the preceding annual accounts except where any changes, and the reasons for them, are disclosed. This interim report has been prepared in accordance with the basis set out in Note 7. 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. 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 2007.
