A new name above the threshold

IQE (LSE:IQE) published a holding notification on Monday 9 November 2026 showing that Richard Griffiths had moved from below 3% of the company's voting rights to 5.56%, with the relevant threshold crossed on 6 November. Of that, 4.01% is held directly through 53,392,362 ordinary shares and a further 1.55%, equivalent to 20,620,062 voting rights, through contracts for difference.

About compound semiconductors

IQE grows thin crystalline layers on wafers, a process known as epitaxy, using compound materials such as gallium arsenide and indium phosphide. These wafers are the starting point for devices that handle radio signals, light and sensing, including the lasers used in data centre and AI networking. The company supplies wafers to device makers, which means its Demand follows the production plans of a small number of large customers.

The company and its recapitalisation

IQE, based in Cardiff, makes epitaxial compound semiconductor wafers used in wireless, photonics and sensing applications, including lasers for data centre and AI networking. In April 2026 it ended a strategic review and announced a fundraise of about £81m at 19.8p per share. The package included a £30m subscription by MACOM Technology Solutions, £15m of new zero-coupon secured convertible notes issued to MACOM, £22.8m reinvested by existing noteholders, an £11m placing and a £2m retail offer. Proceeds were earmarked to repay bank debt, redeem existing Loan notes and strengthen the balance sheet.

Reading the numbers

The 5.56% figure reconciles with LSE:IQE's amended total voting rights notice of 4 November, which gave 1,331,362,303 voting shares at 31 October after excluding 4,115 treasury shares. Combined, the direct shares and CFD exposure total 74,012,424 voting rights, roughly 5.56% of that denominator.

Because the previous position was below the 3% disclosure level, the notice implies a substantial build. On that basis, 3% of the current denominator is about 39.9m voting rights, so the combined exposure rose by at least roughly 34m shares or equivalents before 6 November.

The CFD element is significant. A contract for difference gives economic exposure to price movements, but voting rights are typically retained by the counterparty unless the position is converted into shares. Only the directly held 4.01% therefore represents shares the holder can currently vote.

Why it matters

IQE's share count has expanded sharply through the fundraise and continuing Warrant exercises; a notice on 22 October recorded chair Mark Cubitt exercising 1,709,803 warrants at 13.5p. In a widened register, the emergence of a new holder above 5% alongside a strategic Shareholder such as MACOM adds another concentrated position. That can affect liquidity, the dynamics of any future votes, and the likelihood of further notifications if the holding rises or falls through whole-percentage thresholds.

It does not, on its own, reveal intent.

Future dilution is also possible. The £15m of convertible notes issued to MACOM could add further shares if converted, and any remaining warrants would do the same, steadily diluting any fixed holding over time.

Caveats and risks

A CFD position can also be closed quickly, so the economic stake may change without a corresponding move in registered shares. More broadly, LSE:IQE's valuation depends on execution in its photonics and data centre markets and on the MACOM Supply relationship, not on register changes.

The Recapitalisation in detail

The April 2026 fundraise of about £81m at 19.8p per share included several parts. MACOM contributed £30m by subscription and £15m through convertible notes, existing noteholders reinvested £22.8m, the placing raised £11m and the retail offer £2m. These add up to £80.8m. The use of proceeds, namely repaying bank debt, redeeming loan notes and strengthening the balance sheet, indicates that the main purpose was to reduce borrowing, not to fund growth directly.

What the holding figures show

The direct holding of 53,392,362 shares at 19.8p, the raise price, would be worth about £10.6m, though the investor's actual purchase prices are not disclosed. The CFD exposure of 20,620,062 voting rights adds about 1.55%. The total of 74,012,424 rights divided by 1,331,362,303 gives 5.56%, matching the notice. Each additional 1% of the voting rights equals about 13.3 million shares, so the 5.56% position is equivalent to a little over five and a half such blocks.

Notification thresholds

Under UK disclosure rules, holders must notify the company when their voting rights cross specified levels, starting at 3% and moving in steps. Holdings through certain financial instruments, such as CFDs, are included in the calculation in some circumstances, which is why the notice contains both direct and instrument figures. The next threshold above 5% is 6%, so a further rise of about 0.44 percentage points, or about 5.9 million shares, would trigger another notice.

Warrants and convertible notes

The exercise of 1,709,803 warrants by chair Mark Cubitt at 13.5p shows that warrants priced below the raise price are being used, and each exercise adds shares to the total. Convertible notes of £15m held by MACOM could convert into shares, which would increase the share count and reduce the percentage held by every other shareholder, including the new holder.

The role of strategic investors

When a large strategic investor such as a customer or supplier holds shares, it can influence a company's plans, though its stake is limited by the disclosure and Takeover rules that apply to listed companies. In the case of IQE, the Investment by MACOM combined a share subscription with convertible notes, which gives it both a shareholding and a potential future claim on additional shares.

For other shareholders, the key questions are how much dilution may follow from conversion, and whether the Balance Sheet is stable enough for the company to invest in capacity. The April package was designed to address the second question by reducing debt.

A holder that crosses 5% must continue to notify the company each time its holding changes through a whole-percentage threshold, so further disclosures would be expected if the position grows or shrinks. This provides a public record of changes in the register, which other investors can follow.

The wafer Business serves customers in wireless, photonics and sensing, and demand from data centre and AI networking is an important driver of interest in the company's lasers and related products. The company's results will show whether orders from those markets are growing, and the share register reflects investors' views on that outlook.

What to watch

Further holding notifications would show whether the position is being built or reduced, and the next monthly total voting rights notice, due around the start of December, will update the denominator as warrants continue to be exercised.
