A result already signposted

Renew Holdings (LSE:RNWH) will publish preliminary results for the year to 30 September 2026 on 24 November. The headline outcome has largely been disclosed already: in a year-end trading update on 1 October, the board said it expected record Revenue and record operating profit, in line with market expectations, alongside a record order book.

With the totals guided, the more useful questions concern the quality of growth, the state of individual end markets, and how a run of acquisitions is changing the group.

The Business in brief

LSE:RNWH provides engineering services to maintain and renew UK infrastructure, working largely under long-term frameworks in rail, water, energy, highways and other regulated or government-funded markets. Its income therefore tracks multi-year spending cycles rather than one-off construction projects. The group reports a single operating segment, Engineering Services, and gives qualitative commentary on each sector.

The half-year starting point

The interim report for the six months to 31 March 2026 gives the baseline. Revenue rose 3% to £589.0m and adjusted operating profit increased to £33.4m from £32.0m, a Margin of 5.7%. Statutory profit before tax was £25.5m after £6.6m of one-off items and amortisation. Adjusted Basic Earnings Per Share from continuing activities were 30.90p and the Interim Dividend was raised 5% to 7.00p. The order book stood at £945m against £908m a year earlier.

Organic growth in that half was only 2.2%, and management said it expected it to accelerate in the second half. That expectation is the first thing to test on 24 November, because acquisitions contributed meaningfully to reported growth.

Sector questions for the results

Water should be a focus. The current regulatory period, AMP8, runs to March 2030 with around £104bn of committed investment, and the October update pointed to solid performance in water and energy. Rail is less certain. At the half-year, Renew said renewals activity was subdued as Network Rail prioritised reactive maintenance, even though the Control Period 7 settlement to March 2029 commits £31.9bn. Any change in that tone would matter for the second half and for 2027.

Energy carries a specific item: the interim report said the French Subsidiary of wind turbine services business Full Circle was under restructuring review. Investors will look for the outcome and any associated cost. Highways spending under the RIS3 programme, set out in March 2026 at around £8.4bn of renewals over five years, is another medium-term support.

Acquisitions and risks

LSE:RNWH has been an active buyer. Emerald Power, completed in October 2025 for up to £11.3m, was followed by Edwards Diving Services for up to £13m and the small PWR-X cable jointing business, then the larger Porter Brothers deal announced on 28 October. Integration, deferred consideration and contingent payments all need monitoring, and acquired growth can mask softer organic trends.

Other risks include dependence on a concentrated group of public and regulated clients, the timing of framework awards, labour availability and cost Inflation on fixed-price elements. Statutory profit has also been held below adjusted profit by one-off items and amortisation, a gap that is likely to persist while acquisitions continue.

The half-year baseline

Revenue of £589.0m, up 3%, with organic growth of 2.2%, suggests that about 0.8 percentage points came from acquisitions. Adjusted operating profit of £33.4m on revenue of £589.0m gives a margin of 5.7%, compared with about 5.5% a year earlier, since £32.0m on about £571.8m is roughly 5.6%. The order book of £945m compared with £908m a year earlier is an increase of about 4.1%, so forward work has grown slightly faster than revenue.

Statutory profit before tax of £25.5m compares with the adjusted figure of £33.4m, a gap of £7.9m, of which £6.6m was one-off items and amortisation.

The year-end update

The board expects record revenue and operating profit, in line with market expectations, alongside a record order book. For a business that gave half-year revenue of £589.0m, a full-year figure well above £1.1bn seems likely, though the company has not given exact figures. The results on 24 November will show the figures and the second-half trend.

The regulated markets

AMP8 is the regulatory period for water companies in England and Wales, running to March 2030, with around £104bn of committed investment. Frameworks in such periods run for several years, which gives engineering firms visibility. In rail, Control Period 7 to March 2029 commits £31.9bn, but at the half-year the company said renewals activity was subdued as Network Rail prioritised reactive maintenance, which means work was delayed. Highways, energy and other markets also contribute.

Dividends and earnings

The interim dividend of 7.00p, up 5%, follows the group's record of progressive dividends. Adjusted earnings per share of 30.90p for the half means the interim dividend is about 23% of earnings in that half. The company has not set out full-year earnings, which the results on 24 November will provide.

What to check in the full results

Investors can look at the split of revenue by sector, the margin in the second half compared with 5.7%, the order book compared with £945m at the half-year, and organic growth compared with the 2.2% in the first half. They can also look at net Debt and cash flow, and at how acquisitions have been integrated.

Acquisitions and organic growth

When a group buys other businesses, reported growth includes revenue from those purchases. The organic rate, which excludes them, shows how much the existing businesses grew. At the half-year, organic growth was 2.2% against reported growth of 3%, and management expects the organic rate to rise in the second half, which the full-year results will test.

Beyond 24 November

The results should set out the final dividend, the order Book Value at 30 September and the board's outlook for the 2027 financial year. They will also be the first audited accounts to include Emerald, Edwards Diving and PWR-X for a full or part year, giving a clearer view of how much of Renew's growth is now bought rather than organic. The board has said its cash position gives flexibility for further acquisitions, so commentary on the pipeline is likely.
