IMI
Industrial Goods and Services Share price 3,090p Market cap £7.4bn Overall fit 640 /1000

Genuine AI-receiver exposure via data-centre cooling and power orders (200%+ growth), fortress balance sheet, and consistent execution — but valuation is fair not cheap, and operating leverage is moderate rather than software-like. A strong buy with reservations rather than a top-band pick.

Fair value range 2,850p–3,400p Mid case · £7.4bn
Absolute upside +0.6% vs current market cap
Conviction 4/5 confidence in fair call
Supports the call
  • Six-year consistent execution against stable financial framework
  • Clean disclosure with strong statutory-to-adjusted reconciliation
  • Multiple valuation methodologies converge in a tight range
Limits the call
  • Fair value sensitive to durability of data-centre order momentum
  • Cyclical Industrial Automation/Transport exposure clouds through-cycle earnings power
Methodology

Forward P/E cross-checked with peer multiples and FCF yield

In one line · bull case

Quality UK fluid-control specialist with real AI-receiver exposure through data-centre cooling and power infrastructure orders, fortress balance sheet, and consistent execution — available at a fair rather than cheap multiple.

In one line · biggest risk

At ~22x forward earnings the stock is priced for continued execution — any softening in data-centre orders or Middle East shipment disruption could compress the multiple.

Drivers
AI beneficiary 58 /100
Direct data-centre cooling exposure (£18m H1 2026 vs £6m H1 2025) plus power/nuclear orders tied to AI electrification, but data-centre orders are still a small share of Group revenue.
Operating leverage 55 /100
H1 2026 delivered 5% revenue growth into 8% OP growth (1.6x); aftermarket mix and manufacturing absorption help but this is not a software-like leverage profile.
Earnings vs expectations 62 /100
Consistent in-line-to-modest-beat delivery against own guidance across every period reviewed; management guides conservatively.
Growth momentum 65 /100
Sixth consecutive year of MSD organic growth on track; adj EPS 10% CAGR since 2019 with Growth Hub orders +22% in H1 2026.
Moat 65 /100
Installed base of 200,000+ severe-service valves plus applications engineering expertise creates real switching costs and drives the ~45% aftermarket mix.
Earnings quality 80 /100
Cash conversion 96% in 2025 with statutory operating profit growing faster than adjusted, indicating clean underlying earnings.
Management quality 78 /100
Roy Twite delivered five consecutive years of MSD organic growth, +580bps margin, +260bps ROIC on bolt-on M&A, disciplined £500m buyback timing.
Cyclicality 55 /100
Diversified across sectors but Industrial Automation, Transport (heavy-duty truck) and Life Science device markets have shown mid-teens organic swings.
Leverage 25 /100
Net debt/EBITDA 1.2x at H1 2026, within 1.0-2.0x target range, with £209m undrawn RCF; balance sheet is a strategic asset.

IMI PLC (LSE: IMI) — Research Note

Executive summary

IMI is a UK-listed FTSE 100 specialist in fluid and motion control (valves and actuators), operating through two platforms — Automation (Process Automation + Industrial Automation) and Life Technology (Climate Control, Life Science & Fluid Control, Transport). The company has delivered five consecutive years of mid-single-digit organic growth and 580bps of margin expansion since 2019, reaching a 20.0% adjusted operating margin in 2025 with 96% cash conversion and 14% ROIC. The most important valuation point today is that IMI offers meaningful, quantifiable AI-cycle exposure (data-centre cooling orders +200% YoY in 2025 and again in H1 2026; power/nuclear order intake linked to data-centre electrification) at a fair-to-full multiple, backed by a fortress balance sheet.

Fair value estimate

  • Fair value range: 2,850p – 3,400p per share (implied market cap £6,760m – £8,060m using 236.8m shares).
  • Methodology: forward earnings multiple, cross-checked with peer multiples and DCF sanity. 2026 adj EPS guidance is 136–142p; using 140p at 20x–24x forward P/E gives 2,800p–3,360p. On 2027E EPS of ~150p, 20x–22x gives 3,000p–3,300p. FCF yield ~4.2% on 2025 delivered £290m, growing with buyback.
  • Peer cross-check: Spirax-Sarco (~25x), Halma (~30x), Rotork (~20x), Weir (~18x). IMI's mix of aftermarket recurrence (~45% of revenue), higher cyclicality vs Spirax/Halma but better balance-sheet quality than Weir supports ~22x.
  • Current mcap £6,953.5m vs mid fair value £7,410m ⇒ upside ~7% (range: ‑3% to +16%). Fair, not obviously cheap.

Sector context

  • Sector: Industrial Goods & Services (ICB) — process automation / flow control specialty industrials.
  • IMI's quality profile is above-average for the sector: 20% adj operating margin, 96% cash conversion, 14% ROIC, net debt/EBITDA 1.2x, and consistent organic growth all sit at the top-quartile end of UK industrials.
  • Listed peers: Spirax Group, Rotork, Weir Group, Halma (adjacent). Global comparables include Emerson Electric, Flowserve, and Watts Water.

Investment thesis

  • Data-centre and electrification tailwind is a real AI-receiver angle. Climate Control data-centre orders scaled from £7m (2024) → £18m (2025) → £18m in H1 2026 alone (liquid-cooling systems). Process Automation reports 20% organic growth in conventional Power orders in 2025 tied to data-centre energy demand, plus a £48m nuclear order in H1 2026 covering >10 years of deliveries 2026-03 FY results; 2026-07 H1 results.
  • Compounding earnings machine with disciplined capital return. Adj EPS 10% CAGR since 2019, ROIC +260bps since 2019, £500m buyback announced March 2026 (£250m completed by H1), 10% dividend increase, and £400m+ in bolt-ons deployed 2019-2025 while lifting ROIC — evidence of consistent execution 2026-03 FY results.
  • High-margin aftermarket + installed base moat. ~45% of revenue is aftermarket; database of 200,000+ severe-service valves supports dedicated aftermarket sales force; Process Automation aftermarket orders +7% organic in H1 2026 despite tough comparators. Aftermarket has higher margins and is more recurring than new construction 2026-07 H1 results.

Key risks

  • Middle East / geopolitical shipment risk. ~6% of 2025 revenue is Middle East, principally Process Automation. Guidance depends on shipments completing by year-end; disruption could push revenue into 2027 2026-05 Trading Update; 2026-07 H1 results.
  • Cyclicality of core industrial end markets. Industrial Automation, Transport (heavy-duty truck), and Life Science device markets have all shown mid-teens organic swings across the period; the mid-single-digit "through-cycle" delivery masks meaningful sector volatility 2025-08 Interim; 2026-03 FY results.
  • Valuation vulnerability if AI/data-centre orders decelerate. At ~22x forward earnings, IMI is priced for continued mid-single-digit growth and margin defence. A cyber-security investment headwind is already flagged for 2026; any Growth Hub or data-centre softness would compress the multiple 2026-07 H1 results — cyber investment noted.

Operating leverage

IMI's operating leverage is moderate, not extreme. H1 2026: 5% organic revenue growth translated to 8% organic adjusted operating profit growth — roughly 1.6x leverage. Automation platform showed better leverage (5% revenue → 12% OP, +100bps margin) because Process Automation aftermarket carries substantially higher gross margins. Fixed-cost intensity is modest for a specialty industrial: cost of sales was 51% of revenue in H1 2026 (roughly 49% gross margin), and net operating costs (SG&A + R&D) were 30% of revenue — leaving a variable/fixed mix more typical of engineered products than of software. R&D is ~3.1% of sales. The clearest operating-leverage levers are (i) growth in Process Automation aftermarket (higher-margin) and (ii) fixed-manufacturing absorption after the 2019-2024 restructuring closed 20 sites 2025-08 Interim; 2026-03 FY results. Long-tail upside on a data-centre demand surprise is real but would likely produce ~50% incremental profit uplift on a 10-20% revenue beat, not multiples of profit. This is a solid 60/100 operating-leverage business, not an 85+.

Value-trap signals

None identified. Track record of mid-single-digit organic growth, margin expansion, high cash conversion, and progressive dividend with disciplined M&A. Cyber incident (Feb 2025, £27m adjusting item) was one-off and disclosed transparently. Truflo Marine disposal (£225m EV, closing Q3 2026) reflects proactive portfolio management, not weakness.

Earnings vs expectations

Across the filing set, IMI has consistently met or modestly beaten its own guidance:

  • FY2023 guidance (112p-117p adj EPS at July 2023) → delivered 116.8p — met upper end.
  • FY2024 guidance (120p-126p at Nov 2024) → delivered 122.5p — met.
  • FY2025 guidance (129p-136p at Aug 2025; reaffirmed Nov 2025) → delivered 132.3p — met midpoint.
  • FY2026 guidance (136p-142p at March 2026) → reaffirmed at Q1 (May 2026) and H1 (July 2026) despite Middle East disruption and cyber investment headwind. Pattern: reliable delivery, no misses, no material beats — management guides conservatively and delivers within range.

Conviction: 4 — high

Anchoring factors: (i) clean, well-disclosed statutory-to-adjusted reconciliation; (ii) six-year track record of consistent execution against a stable financial framework; (iii) multiple valuation methodologies (forward P/E, peer multiples, FCF yield) converge in a tight range. Limiting factors: (i) fair value is sensitive to the assumed multiple, which is itself a function of how durable one thinks the data-centre orders and margin expansion are; (ii) cyclical Industrial Automation and Transport sectors add uncertainty to the through-cycle earnings power estimate.
