On October 8, 2026, CIG (HKEX: 06166) simultaneously announced two financing arrangements: a placement of 18.446 million new H shares at HK$105.16 per share, and the issuance of zero-coupon convertible bonds with an aggregate principal amount of RMB 3.96 billion.
Both financings share the same issuance framework, with total net proceeds of approximately HK$6.535 billion, of which the placement raised approximately HK$1.930 billion and the convertible bonds raised approximately HK$4.606 billion. The placement completed settlement on October 12, while the convertible bonds were issued on October 14 and listed on the Vienna Stock Exchange's Vienna MTF.
The pricing benchmarks were fully synchronized — the placement price of HK$105.16 per share represented a discount of approximately 8% to the October 7 closing price of HK$114.30, while the initial conversion price of the convertible bonds at HK$128.82 represented a premium of approximately 12.7% to the same closing price. Combined with the approximately HK$1.967 billion net proceeds from the first placement in June 2026, CIG's two financings together raised approximately HK$8.5 billion in net proceeds.
Two fundraisings, two different logic
On June 4, 2026, CIG completed its first H-share placement since listing, issuing 15.6 million shares at HK$126.66 per share, raising approximately HK$1.967 billion in net proceeds. The use of proceeds at that time was highly focused: 80% for strategic reserves of core components, including high-speed DSP chipsets required for 800G and 1.6T optical modules, 100G/lane and 200G/lane silicon photonic chipsets, and continuous-wave laser devices ranging from 70mW to 200mW. The company cited significantly extended delivery cycles for these core components, requiring deposits or advance payments to lock in production capacity.
Four months later, the logic behind the second financing had changed. June was about "snapping up components," while October was about "expanding production capacity." The placement price dropped from HK$126.66 to HK$105.16, while the convertible bonds locked in a future conversion price at a premium of HK$128.82.
The combination of "discounted placement plus premium bond issuance" is a common practice for listed companies when their share prices are at relatively high levels. The placement portion trades a discount for immediate capital, while the convertible bond portion locks in a future conversion price at a premium. If the share price rises above HK$128.82 during the conversion period, bondholders will convert their bonds, and the company achieves equity financing at a higher price. If the share price fails to reach the conversion price, the company only needs to repay the principal without equity dilution. For CIG, this is an arrangement that allows for both offense and defense.
Where the HK$6.5 billion is headed
The HK$6.5 billion financing is highly concentrated in its direction: optical module capacity expansion. According to the October announcement, 55% of net proceeds will be used to expand optical module production capacity, 30% for strategic investments in the upstream supply chain, and the remaining 15% for working capital. The company's capacity target is to expand high-speed optical module annual production capacity by at least 10 million units on top of the existing base by the end of 2027.
Supporting this expansion plan is the explosive demand for AI computing power. In its announcement, CIG cited industry data stating that the four major North American cloud service providers are expected to spend over US$700 billion in capital expenditure in 2026, a year-on-year increase of more than 70%. The Ethernet optical module market is expected to grow 120% in 2026, with growth expectations maintained at a high level of 76% in 2027.
From a performance standpoint, CIG is indeed in a growth cycle. In the first half of 2026, it achieved revenue of RMB 2.705 billion, up 32.92% year-on-year; net profit attributable to shareholders of RMB 328 million, up 171.08% year-on-year; and a gross margin of 30.77%. The optical module business recorded revenue of RMB 1.675 billion, matching the full-year 2025 figure in just six months, accounting for approximately 62% of total revenue.
The boundaries of dilution
After the placement was completed, CIG's A-share proportion was diluted from 74.84% to 65.20%, with total share capital increasing by approximately 5%. The shareholding ratio of the controlling shareholder and its concert parties was passively diluted from 9.22% before the placement to 8.78%.
The dilution from the convertible bond portion has clear boundaries. The initial conversion price of the RMB 3.96 billion convertible bonds is HK$128.82, representing a premium of approximately 12.7% over the current share price. If the share price fails to reach this level in the future, bondholders will not choose to convert, and the company will only need to repay the principal upon maturity in October 2027. Additional share issuance would only occur if the share price rises significantly and triggers conversion conditions. If all bonds were converted at the initial conversion price, total share capital would increase to approximately 423 million shares, a rise of about 14.8% — but this is a conditional outcome, not an inevitable fact.
The market's first reaction was cautious. After the financing announcement was disclosed on October 8, CIG's H shares briefly surged 7% before pulling back, closing down 3.06% that day, while A shares closed down 6.01%. In the following trading days, the H-share price continued to decline, closing down 5.32% at HK$104.9 on October 9, slightly below the placement price. On October 12, H shares fell another 6%+, trading at HK$97.9 intraday.
But market sentiment shifted after the financing was completed. On October 16, CIG shares rose more than 5% intraday and received a stake increase from Morgan Stanley. The market's digestion of the financing gradually shifted from initial "dilution anxiety" to expectations for capacity delivery after the funds are deployed.
An expansion that needs verification
CIG's core customers are North American cloud providers and telecommunications equipment manufacturers. 800G optical modules have achieved large-scale delivery, and 1.6T optical modules have completed multiple rounds of customer validation. The direction of capacity expansion is clear, but whether the HK$6.5 billion financing can translate into simultaneous revenue and profit growth depends on two variables: whether North American cloud providers' capital expenditure materializes as expected, and whether the company's capacity ramp-up speed can match customer demand.
From the June financing to "snap up components" to the October financing to "expand capacity," CIG completed a two-step layout from supply chain security to production scale within four months. What this HK$6.5 billion buys is a complete chain from upstream chip security to downstream delivery capability. The premium conversion price of the convertible bonds defers the timing of equity dilution until after the share price truly delivers on growth — for existing shareholders, this is a gentler choice than a direct share issuance.
