EXHIBIT 99.1 (INSITUFORM-TECH)(INSU) Insituform Technologies, Inc. Reports Second Quarter Earnings Per Share from Continuing Operations of $0.18 Chesterfield, MO - July 24, 2003 - Insituform Technologies, Inc. (NASDAQ National Market: INSU) (the "Company") today announced second quarter results. Consolidated revenues from continuing operations were $124.8 million for the three months ended June 30, 2003, a 5.3% increase compared to $118.5 million in revenues in the second quarter of 2002. Consolidated income from continuing operations decreased by 40.8% to $4.9 million, or $0.18 per share, compared to $8.2 million, or $0.31 per share, in the second quarter of the prior year. Consolidated net income for the second quarter of 2003 was $4.6 million, or $0.17 per share, including a loss of $0.3 million, or $0.01 per share, from discontinued operations compared to $7.3 million of consolidated net income in the second quarter of 2002, or $0.28 per share, including a loss of $0.03 per share from discontinued operations. For the first half of 2003, revenues increased 8.0% to $248.1 million from $229.7 million in the first six months of 2002. Income from continuing operations was $11.2 million, a decrease of 20.7% from $14.2 million in 2002, or $0.42 and $0.53 per share, respectively. Discontinued operations had minimal impact on earnings year-to-date but accounted for a $2.5 million loss, or $0.09 per share, in the first six months of 2002. Consequently, consolidated net income decreased 3.6% to $11.2 million from $11.6 million for the first six months of 2003 compared to the first six months of 2002. As a reminder, the preliminary second quarter 2003 earnings discussed by the Company on July 10 included initial estimates of accruals and reserves. These were finalized as part of the closing process, and an additional $0.04 per share of charges were recorded primarily for casualty losses, bad debt, and severance. The second quarter 2003 shortfall from the original forecast was due to unanticipated contract completion costs in Elmore, lower margins and losses on some contracts in Kinsel, and a revenue shortfall in two cured-in-place pipe ("CIPP") operations. Results were also impacted by higher-than-expected casualty losses, healthcare claims and write-off of obsolete small diameter equipment and inventory. The following earnings presentation details unusual items and is intended to provide insight into results of operations for the second quarter of 2003. The reconciling items highlighted below are the significant charges that were not anticipated in original second quarter 2003 earnings guidance. EPS from Continuing Operations Adjusted for Unanticipated Items $0.28 Losses Incurred to Close-Out Elmore Jobs (0.04) Revised Estimate of Insurance Liability (0.03) Write-off of Obsolete Small Diameter Equipment and Inventory (0.02) Other Accrual Adjustments and Severance (0.01) Reported EPS from Continuing Operations $0.18 Loss from Discontinued Operations (0.01) Net Income $0.17 Operating cash flow from continuing operations improved over the already strong showing from the first quarter of this year. Operating cash flow from continuing operations increased to over 2.5 times income from continuing operations year-to-date. Net debt has fallen to $16.7 million at June 30 compared to $26.1 million at the end of March 2003, and cash on hand increased 41.0% to $117.6 million at June 30 from $83.4 million at March 31, 2003. Continued focus on job close-out and receivable collection in domestic rehabilitation and the collection of receivables from large tunneling projects have yielded a reduction of 6.5% in days sales outstanding since the beginning of the year. Orders during the second quarter were strong, particularly in the domestic CIPP business where orders exceeded revenues by 26.9%. However, the distribution of backlog is not even. One of the domestic CIPP units, Kinsel, and the Elmore division of Affholder face sub-optimal backlog levels. These units will continue to confront the challenges posed by their backlog positions for the balance of the year. Due to recent management changes, the Company will incur severance costs during the third quarter of 2003. Higher insurance costs are expected to continue to impact margins into the future when compared with prior periods. The combined impact of severance and insurance is expected to be $0.04 to $0.05 per share in the third quarter of 2003. The Company has decided that it will not give specific earnings guidance for the third and fourth quarter of 2003.
