SIG is a European distributor of insulation, interiors and roofing materials with about £1.3bn of sales in the first half of 2026. Construction demand has stayed weak since 2023, and SIG's operating profit has fallen from £80m in 2022 to a guided £25m for 2026. It carries about £530m of net debt, including leases, and management has set out a plan to cut costs, raise cash and bring borrowings down. The shares fell from 33p at the end of 2023 to 9.0p at the latest close on 14 October 2026.
A middleman for builders' materials, on thin margins
SIG buys building products and sells them to trade customers such as roofing contractors and specialist installers. It reports in six units. UK & Ireland Interiors sells insulation, drylining and construction accessories, and the Irish arm also runs three small contracting businesses. UK Roofing is a roofing merchant that includes a Building Solutions arm. France combines LiTT (insulation and interiors) and Larivière (roofing). Germany is Wego/Vti (interiors, flooring and insulation). Poland and Benelux complete the group.
Group buying is about £2bn a year. SIG keeps roughly 24p of every £1 of sales as gross profit, then pays for branches, staff and delivery. Little is left. The half-year operating margin was 0.8%. That makes profit very sensitive to volumes and prices. The company calls this operational gearing and says it works in both directions. 4 Aug 2026 4 Mar 2026 5 Aug 2025
Inflation faded, volumes sank
In 2022 SIG earned £80m of underlying operating profit. In 2023 passing on supplier price rises added about 5% to sales, but the effect faded in the second half, and weaker demand across European construction cut profit to £53m. In 2024 volumes and prices both fell, and profit dropped to £25m. The company took impairment charges on UK Interiors of £34m in 2023 and £7m in 2024.
The company cut guidance on 12 October 2023, from a higher level to £50m-£55m. It cut again on 24 June 2024, to £20m-£30m, and its shares fell from 33p at the end of 2023 to 25p by June 2024. Management responded with restructuring. It cut 430 jobs in 2024, closed 17 branches and set the 'GEMS' strategy (grow, execute, modernise, specialise). The Capital Markets Event on 23 November 2023 introduced a medium-term target of a 5% operating margin. 12 Oct 2023 23 Nov 2023 5 Mar 2024 24 Jun 2024 6 Aug 2024 5 Mar 2025
Refinancing at a high price
In October 2024 SIG replaced its €300m 5.25% bond due 2026 with a new €300m bond due 2029 at 9.75%. It also extended its £90m revolving credit facility, a bank line that has stayed undrawn, to 2029. This removed a near-term repayment deadline. It also raised the cost of the debt. Interest and financing cost £26m in the first half of 2026, against £10.5m of operating profit. 14 Oct 2024 18 Oct 2024 23 Oct 2024 4 Aug 2026
Cost cuts lifted profit, but the shares kept sliding
In 2025 SIG cut underlying operating costs by £39m. Operating profit rose 28% to £32m, in line with market expectations. UK Interiors improved by £9m and Benelux cut its losses by £3m. Sales were flat on a like-for-like basis (excluding acquisitions, disposals, currency and the effect of branch openings and closures). Free cash outflow shrank to £12m from £39m. The year still produced a statutory loss of £62m, including £30m of impairments, and leverage stayed at 4.7 times earnings (net debt to EBITDA).
CEO Gavin Slark announced in May 2025 that he was leaving for Travis Perkins. Pim Vervaat took over on 1 October 2025, and the group paid no dividend for 2025. The shares fell to 10p by the end of 2025. 9 May 2025 8 Jul 2025 4 Mar 2026 13 Jan 2026
2026: a new plan, then another cut
In January 2026 Vervaat set out 'Vision 2030'. It aimed for an operating margin of 3%-5% through the cycle, with a procurement saving of at least 1% of spend from 2027. First-quarter like-for-like sales then fell 5%, which the company blamed on weak demand and poor weather. On 16 July 2026 it cut 2026 profit guidance to about £25m. Analysts had expected £28m. The 4 August results confirmed first-half operating profit of £10.5m, down from £15.4m. 13 Jan 2026 4 Mar 2026 30 Apr 2026 16 Jul 2026 4 Aug 2026
What explains the record
Two things stand out. First, thin margins mean small changes in sales move profit sharply. Weak construction demand, falling volumes and price pressure have outweighed savings that were real. Second, lease and bond debt costs far more than the business earns at present, so profit gains do little for shareholders yet.
Management has delivered on its cost targets but not on its profit guidance. It reached £38m of annualised savings by mid-2025. It cut profit guidance in October 2023, June 2024 and July 2026. The operating margin has stayed between about 1% and 2% since 2023, and it was 0.8% in the latest half-year. Management has not given reasons for the weak demand beyond market conditions and weather. 5 Mar 2024 24 Jun 2024 5 Aug 2025 4 Mar 2026 16 Jul 2026 4 Aug 2026
New leaders, a wider plan, and a softer margin target
Vervaat is CEO and Chair-designate. Simon Kesterton became CFO on 1 May 2026, after Ian Ashton left for TT Electronics. On 9 October 2026 the company said Kesterton will become CEO on 1 May 2027, with Vervaat moving to non-executive Chair. A new CFO will be named later.
The margin goal has been loosened. In November 2023 and again in March 2025 the target was 5% in the 'medium-term'. In January 2026 it became 3%-5% 'through the cycle'.
Vervaat and Kesterton have bought shares in small amounts. Vervaat's purchases were £44k in October 2025, £50k in January 2026 and £14k in May 2026. Kesterton has bought several times since May 2026, including £19k on 5 October. Azvalor Asset Management raised its holding to 13.0% in September 2025. The Wellcome Trust cut its stake to 2.72% in August 2026. 23 Nov 2023 5 Mar 2025 13 Jan 2026 10 Apr 2026 30 Apr 2026 9 Oct 2026 23 Oct 2025 15 Jan 2026 13 May 2026 5 Oct 2026 3 Sep 2025 6 Aug 2026
Still shrinking profit, with tight liquidity
Like-for-like sales fell 1.5% in the first half of 2026, with Q2 up about 1%. UK Roofing grew 1.7% and earned £7.3m. UK & Ireland Interiors profit fell to £2.3m from £5.5m. Germany broke even, and France earned £4.7m after earning £7.2m a year earlier. Poland and Benelux gained share. Statutory operating profit was £5.3m and the half-year statutory loss was £21m.
Free cash outflow was £16m. Net debt was £532m, including £323m of leases. Liquidity was £154m: £64m of cash plus the undrawn £90m facility. The company says it expects to keep liquidity healthy and to cut net debt in the second half. 4 Aug 2026 16 Jul 2026
A £50m profit lift, in a market not expected to help
The company expects about £25m of operating profit for 2026. Its plan, stated in full on 4 August 2026, targets a £50m run-rate improvement in operating profit by mid-2028 and at least £100m of cash generated by the end of 2027. It also targets leverage below 3.0 times and a 3%-5% operating margin through the cycle. The levers are procurement, back-office simplification, property and logistics savings, disposals of underperforming businesses, working-capital changes such as factoring, and AI tools. The company has not named which businesses it would sell.
Management does not expect the market to help. The CEO said:
The open questions are whether savings can outrun wage inflation and price pressure, whether disposals and working capital can deliver the cash, and whether profit can cover the 9.75% bond. The company has restated its commitment to return to paying a dividend only when it is prudent to do so. 4 Aug 2026 16 Jul 2026 4 Mar 2026 9 Oct 2026
“The markets are not anticipated to recover during the remainder of 2026 and possibly throughout 2027.” 4 Aug 2026
