IQE shares fall as FY25 core earnings slump 60% despite 2026 growth forecast

IQE reported full-year 2025 revenue of £97.3 million, down 18% year on year, while adjusted EBITDA fell 60% to £3.2 million and adjusted loss before tax widened to £27.9 million. The company also completed an £81 million fundraise, which should leave net cash inflows of £27.9 million after repaying its revolving credit facility, and guided for more than 20% revenue growth in 2026 with high-single-digit to low-double-digit adjusted EBITDA. Wireless revenue dropped 40% to £40.1 million, partially offset by 15% growth in photonics to £57.1 million.

Analysis

MACOM’s incremental capital commitment looks less like a generic rescue and more like a targeted option on InP supply chain control. The second-order implication is that the real asset is not IQE’s near-term earnings power but its role as a constrained upstream bottleneck in data-center photonics and AI interconnects; if that supply tightens, MACOM can protect gross margins and reduce dependency on third-party wafer availability. That also raises the bar for smaller compound-semiconductor peers: any customer fearing supply fragility may pre-emptively dual-source or sign longer contracts, which helps the whole InP ecosystem but concentrates bargaining power with the best-capitalized vertically integrated buyers.

The market is likely underappreciating how much of the 2026 guide is a balance-sheet story rather than a pure demand story. A high-single-digit to low-double-digit EBITDA outcome off a still-thin margin base leaves little room for execution slippage, and the fundraise plus debt cleanup only buys time if photonics ramps faster than wireless declines. The key risk window is the next 2-3 quarters: if the AI/datacenter order book doesn’t convert into sustained wafer volume, the company can still look ‘fixed’ while remaining structurally fragile.

Contrarian view: the stock may not be as cheap as the headline drawdown suggests because the equity raise changes the optics of per-share recovery. However, the presence of a strategic note buyer argues downside is more protected than a plain-cycle semiconductor name, so the better trade is not outright short equity but expressing skepticism via volatility or via relative-value against higher-quality compound semi exposure. The setup favors a catalyst-driven rerating if first-half 2026 bookings inflect, but absent that, the market will likely treat the guidance as a funding bridge rather than a durable inflection.

The broader read-through for technology is that AI infrastructure demand is now selective: networking and photonics winners can decouple from analog wireless weakness, but only those with credible financing and customer concentration management will capture the rerating. That means the beneficiaries are likely upstream equipment and design-ins tied to InP, while subscale adjacencies without strategic backing remain vulnerable to dilution and lumpy conversion.

Key Decisions for Investors

• Long MTSI on a 3-6 month horizon as a strategic beneficiary of supply-chain control in InP/photonics; target 15-20% upside if the market starts to price share-gain and margin protection, with downside limited by the strategic stake and implied customer optionality.
• Pair trade: long MTSI / short a weaker, non-strategic compound-semiconductor or wireless exposure for 1-2 quarters to isolate the ‘AI photonics wins, legacy RF loses’ theme; target mean reversion of 10-15% as capital rotates toward better-funded names.
• Use IQE as a tactical event-driven long only on pullbacks after confirmation of order conversion; buy on weakness if Q1/Q2 2026 bookings validate the guide, but size small because execution risk remains high and dilution has already reset per-share economics.
• Buy short-dated call spreads on MTSI into any follow-on data-center/photonics catalyst over the next 1-3 months; the risk/reward is attractive if the market starts treating the stake as a strategic barrier rather than a minor financing event.
• Avoid outright shorting IQE here; if bearish, express it through put spreads or by shorting against stronger photonics peers, since the new funding package reduces near-term insolvency risk and can spark sharp squeezes on any positive order commentary.
