IMDEX Limited
Thesis
IMDEX has built a defensible franchise in mining exploration technology, combining hardware, consumables and an AI-driven geoscience platform protected by more than 550 patents. Revenue and margins are running at record levels, and the business shows genuine evidence of structural mix shift toward higher-margin, stickier revenue. The open question for investors is not whether IMDEX is a good business, the evidence supports that it is, but whether the current share price already assumes a degree of sustained outperformance that leaves little room for disappointment.
The Business
IMDEX supplies technology to mining and energy explorers across three regional drilling services divisions (Americas, Asia-Pacific and EMEA) plus a smaller digital geoscience unit built through five acquisitions in FY26. The core model rents sensors and drilling fluids into active drill programs and increasingly sells connected, subscription-style access to the data those sensors generate. Platform/connected-sensor revenue has grown from roughly 35% to 47% of the group total, the clearest evidence that IMDEX is shifting from a rental and consumables business toward a stickier, higher-margin data business.
Recent Performance
IMDEX's FY26 revenue rose 21% to $520 million, extending a re-rating that has taken the stock to a record 31.3% EBITDA margin. That growth followed a softer FY25, when revenue slipped 3% as exploration activity cooled, meaning the current run compares against an easy base as much as it reflects a genuine step-change in demand. The share price reaction suggests the market has moved beyond simply rewarding the recovery and is now pricing several more years of continued outperformance.
Outlook
We expect revenue growth to decelerate over the next three years as acquisition contributions annualise and exploration spending normalises off record junior funding levels. EBITDA margin is likely to ease modestly from its current record level as competitive and input cost pressures build. Earnings per share should still grow over the period, supported by continued platform mix shift, but the trajectory is one of deceleration from a cyclical peak, not further acceleration from here.
Valuation Context
We build fair value using a probability-weighted discounted cash flow analysis alongside trading multiples benchmarked against mining technology and drilling services peers. The two methods point to different conclusions depending on what discount rate and growth trajectory an investor believes is appropriate for a business whose entire revenue base is linked to exploration activity. That divergence is the crux of the investment debate: the current price requires the market to be comfortable discounting IMDEX's cash flows at a materially lower rate than we consider appropriate for a cyclical, exploration-linked business, or to be underwriting revenue growth well ahead of our forecasts, or both simultaneously.
Key Risks
An exploration cycle reversal, as commodity prices normalise from currently extreme levels, is the largest swing factor for the business. IMDEX's fixed cost base means margins compress faster than revenue falls as drilling volumes decline, and junior mining equity raisings, up sharply year-on-year, have historically never sustained their current pace for more than 18-24 months. Failed cross-selling of the five digital acquisitions completed in FY26 into the core drilling services customer base risks impairment against the substantial goodwill now on the balance sheet. Persistently high interest rates also work against the thesis, keeping the appropriate discount rate for a cyclical, exploration-linked business elevated for longer than the market currently appears to assume.
What to Watch
The thesis-defining event is the S&P Global exploration budget survey due in the first quarter of calendar 2027, which will confirm whether junior mining companies keep deploying capital at the current elevated pace or begin to pull back.

Business
Company Description
IMDEX operates through three regional drilling services divisions, Americas, Asia-Pacific and EMEA, that together account for the bulk of group revenue, plus a smaller Digital Exploration and Knowledge (DEK) unit assembled through five acquisitions completed in FY26. The Americas division is the largest single contributor at roughly half of group revenue. Core products include downhole sensors that measure drilling trajectory in real time, specialised drilling fluids that improve recovery rates, and software that turns the resulting data into geoscience insight. Customers explore for gold, copper, lithium, nickel and cobalt, giving IMDEX some commodity diversification even though the entire revenue base depends on drilling activity continuing.
Where the Growth Is
The clearest growth driver is platform, or connected-sensor, revenue, which has risen from roughly 35% to 47% of group revenue and is growing at 33% year-on-year, nearly three times the 11% pace of the more basic rental and consumables business. Share of wallet, the amount explorers spend with IMDEX per $100 of exploration budget, has expanded from $2.00 to $2.40 over three years. Continued mix shift, plus the possibility the market eventually re-rates IMDEX as a data business rather than a services provider, represents the clearest structural upside case within the current investment debate.
Competitive Position
IMDEX's advantage rests on an integrated hardware-to-software architecture, sensors, fluids and AI-driven geoscience software on a single platform, that no direct competitor currently replicates in full. More than 550 patents protect roughly 72% of revenue, and a network of over 40 service facilities across 100-plus countries gives IMDEX proximity to remote mining regions that would cost well over $200 million to replicate. These advantages appear to be widening rather than eroding: share-of-wallet gains and platform revenue growth outpacing basic rental growth both point to genuine share capture, not simply riding a strong exploration cycle. The competitive position should hold for the next five to seven years on current evidence. The main threat is not a head-on competitor but modularisation: if open, interoperable digital tools emerge that let customers mix and match best-of-breed software rather than buying IMDEX's integrated stack, the pricing premium could compress.
Management & Capital Discipline
Management completed five acquisitions in FY26 across four continents, building on the earlier Devico integration, which gives some confidence the current, larger integration program is executable. Research and development spending has been sustained at roughly 8% of revenue through the cycle, funding the sensor and software pipeline behind the platform mix shift. Short-term incentives tied to EBITDA have been met at 116-120% of target in recent periods, evidence of realistic goal-setting rather than sandbagging. One disclosure stands out: management missed its long-term incentive earnings-per-share growth threshold despite strong revenue growth, an honest admission that tempers an otherwise cycle-peak-confident tone around having "more growth levers than ever."
Financial Position
IMDEX carries net debt at roughly 1.2 times EBITDA, a manageable level with $105 million of undrawn facilities and no debt maturities before June 2029. The balance sheet's main vulnerability is $501 million of goodwill, equivalent to about 73% of shareholder equity, concentrated in the recently acquired digital businesses. That structure means the balance sheet can comfortably absorb a cyclical earnings downturn, but a failure of the digital acquisitions to perform as underwritten would flow through as an impairment rather than simply softer cash flow. Overall financial health is adequate rather than fortress-like.
