Impro Precision: The AI Inflection Is Real — But the Stock Already Knows

Impro Precision: The AI Inflection Is Real — But the Stock Already Knows

The market has moved on from doubting Impro Precision Industries. The stock has nearly tripled over the past year and is up 88% year-to-date. The old story — that this was just another Hong Kong-listed precision manufacturer muddling through cyclical auto and industrial demand — no longer holds. Revenue jumped 23.2% in the first half of 2026 to HK$3.02 billion, with profit attributable to shareholders climbing 21.6% to HK$433.1 million.

That is solid growth. The question is whether a stock that has already run this hard still has room to move higher, or if the rerating is largely in the rearview mirror.

What changed

Impro Precision is a diversified manufacturer of precision metal and plastic components. It makes parts for everything from high-horsepower engines to aerospace systems to medical devices. Until recently, AI was a footnote. Now it is the fastest-growing segment.

The AI piece sits inside the diversified industrials bucket, specifically in data center liquid cooling systems — the metal heat-dissipation hardware that keeps AI servers from melting. That sub-sector revenue surged 38.4% to HK$488.6 million in fiscal 2025. Industrial gas turbines, which supply power to data centers, are another beneficiary.

This is not a small-margin contract manufacturing play. Gross margins in H1 2026 held at 27.8%, up from 26.4% a year earlier. The mix shift toward higher-value AI and data center components is expanding profitability, not just top-line volume.

Management has also been blunt about the direction. The full-year 2026 sales growth forecast sits at 20–25%, up from the 8.7% growth delivered in fiscal 2025. They are allocating roughly HK$850 million in capex for the year, with over 75% directed at the Mexico SLP Campus, where Phase II sand casting begins mass production mid-2026.

The free-cash-flow reality check

Here is where the story gets more complicated. Growth is accelerating, but the cash machine has to prove it can keep pace with the valuation.

In fiscal 2025, free cash flow from operations fell to HK$281.6 million, down from HK$456.2 million the year before. The drop came from working capital absorption tied to growth and the drag from loss-making operations in Mexico and Turkey, both still ramping up. Net gearing improved to 30.4% from 33.6%, and cash on hand stood at HK$720.9 million — so the balance sheet is not under immediate stress. But free cash flow conversion has weakened precisely when revenue is accelerating.

With HK$850 million in planned capex for 2026 — over half of which goes to the Mexico facility that is currently hemorrhaging money — the free cash flow path through the next 12 months depends on two things: the Mexico ramp turning profitable, and the AI/data center segment growing fast enough to offset continued automotive weakness.

The automotive sector, which still accounts for nearly a third of revenue, declined 9.3% in fiscal 2025. Management expects passenger car demand to soften further, with commercial vehicle recovery only resuming from Q3 2026. That means the AI/industrial growth has to carry the weight for most of the year.

The valuation question

Impro Precision trades at roughly 22 times trailing earnings, well above the Hong Kong machinery industry average of around 12 times and a peer group mean near 13 times. The stock is up 147% over the past 12 months, though it has pulled back about 15% over the last 90 days from a 52-week high of HK$11.80.

That premium is not unexplained. The company is growing revenue at mid-to-high double digits with margins improving, and it is positioning itself in the AI infrastructure supply chain. But the premium means the market has already done most of the rerating. A 22x P/E on a HK$16–17 billion market cap prices in a sustained growth story, not just a one-off acceleration.

To justify this multiple, the business needs to deliver on the 20–25% full-year growth forecast while stabilizing or growing free cash flow. If it does, the stock can hold its ground and potentially extend toward the HK$11–12 zone that analysts have targeted. If revenue growth softens to the low-teens range or Mexico losses widen, the valuation looks stretched fast.

The setup

The market is still pricing Impro Precision as a manufacturer with AI upside. But the numbers from H1 2026 suggest the AI upside is no longer prospective — it is already flowing through the P&L. The 23.2% revenue growth, 21.6% profit growth, and 27.8% gross margin show the mix shift is real.

The risk is not whether the business is improving. It is whether the stock has run too far ahead of free cash flow.

What would keep this working: The 20–25% revenue growth forecast holds, Mexico stabilizes toward the back half of 2026, and free cash flow from operations rebounds from the depressed fiscal 2025 level. On that path, the current multiple is defensible, and the stock could test HK$11–12 over the next 12 months.

What breaks it: Revenue growth comes in below 15%, Mexico losses expand beyond what the market expects, or free cash flow weakens further. Any of these would leave a 22x P/E looking expensive on a company that still has meaningful exposure to cyclical auto demand.

The inflection is real. But at these levels, there is little margin for error.
