Earnings Highlights: Airoha (6526) | FY2026 Q2 — Record NT$6.29B Quarterly Revenue, and the Market Buys a 4x Optical Year Before It Hits the Books

This article is for technology and industry trend analysis only and does not constitute investment advice.

Airoha's numbers this quarter are good on their own: record quarterly revenue and EPS of NT$5.25. But what really lit up the earnings call wasn't the NT$6.29 billion already banked — it was management's line on "optical communications": full-year 2026 optical revenue to grow more than 4x over 2025, and more than 3x again in 2027. A company built on mobile, earbud and networking chips is staking its entire growth story on optical interconnect for AI data centers.

• Record revenue, profit jumps in step: FY2026 Q2 consolidated revenue of NT$6.29 billion, up 15.3% QoQ and 13.9% YoY, an all-time quarterly high; EPS of NT$5.25 and net income of NT$886 million, both better than the prior quarter.

• The growth engine has changed hands: This quarter's revenue was carried by the Wired Network Infrastructure and Wireless Edge AI business groups; but the market's attention is entirely on the optical SerDes product line inside wired networking, still on the eve of its ramp.

• The real signal is in the outlook: Optical revenue target of ">4x vs 2025" in 2026 and "another >3x vs 2026" in 2027 — and the entry point is the most pragmatic one, pluggable optical modules and AI data centers, not CPO, which is still in validation.

1. Three Core Signals to Understand First

First, this quarter's strong growth didn't come from optics yet. Within the NT$6.29 billion, the mainstay is still Bluetooth business earbuds (Wireless Edge AI) and existing networking businesses such as broadband, Ethernet and PON (Wired Network Infrastructure). Optics is still a small share; the real ramp comes in 2H26 through 2027. In other words, the market is buying growth that "hasn't happened yet, but has high visibility."

Second, gross margin dipped slightly but held above 50%. Q2 gross margin was 51.2%, down about 1.5 percentage points from Q1's 52.7%, but still within management's full-year commitment to "stay above 50%." For an IC design house ramping new products with a fast-shifting mix, that's a healthy number.

Third, Airoha chose the path that pays fastest. Its optical weapons are 50G/100G/200G SerDes IP and related chips, slotting first into pluggable optical transceivers rather than jumping straight to co-packaged optics (CPO). The upside of this path is orders now and shipments now.

2. Revenue and Financials

FY2026 Q2 hard numbers at a glance:

• Consolidated revenue: NT$6.29 billion, +15.3% QoQ, +13.9% YoY, an all-time quarterly high.

• Gross margin: 51.2% (Q1: 52.7%, down about 1.5pp QoQ).

• Operating margin: 15.0%, implying operating income of about NT$940 million.

• Net income: NT$886 million.

• EPS (after tax): NT$5.25 (Q1: NT$4.47).

Taken together, Airoha's 1H26 revenue was about NT$11.74 billion with EPS of about NT$9.72, both business groups growing in tandem — before the main leg of optical growth is even counted. The point here isn't how pretty a single quarter looks, but the "quality" of the growth: revenue grew double digits QoQ while gross margin eased only slightly and operating margin held at 15%, meaning this growth wasn't bought with price cuts.

3. Technology and Business Highlights: Optics Is the Lead, but Supporting Roles Carried the Quarter

The Wired Network Infrastructure business group (including optics) is the narrative core this quarter. Airoha's approach is to take its long-standing expertise in SerDes and PHY — "moving signals back and forth" — straight into AI data centers:

• Optical SerDes: The product line spans 50G, 100G and 200G SerDes IP, first supplying the electrical-signal chips needed by pluggable optical modules. How hard the SerDes stage is, and why it's the battleground of optical interconnect, we covered in Marvell Pushes 212.5Gbps SerDes to 55dB Reach With 3nm FinFET — Airoha is cutting in at the more pragmatic mid-speed generation, positioning early and qualifying early.

• Broadband and Ethernet into AI data centers: Airoha is bringing carrier-grade 10G-PON technology into data center out-of-band (OOB) management architectures, claiming it can save up to 99% of management rack space for AI data centers; 25G-PON is expected to enter volume production in 2027. It's a classic play of porting "telecom technology" into "the data center."

• LEO satellites: Shipments of 1G and 2.5G PHY chips keep growing — another low-key but steady growth line.

The Wireless Edge AI business group is this quarter's actual revenue pillar. Bluetooth business earbud revenue more than doubled YoY in 1H26, with higher-end applications raising their share and average selling prices (ASP) rising along with them; gaming peripherals and electronic shelf labels (ESL) are also expanding. This business matters because it buys Airoha the time and cash to "wait for optics to ramp."

Airoha's choice to do pluggables first and look at CPO later reflects a very real physics-and-cost bottleneck — why pluggable optical modules hit a wall, and why CPO's turn hasn't come yet, we explained fully in Have Pluggable Optical Modules Hit the Wall? Understand This Bottleneck Before CPO. Where Airoha stands now is precisely the sweet spot where that bottleneck "still holds."

4. Management Outlook: Telling the Growth Story Through Optics

On this call, the outlook clearly carried more weight than the quarter's numbers. Management's key guidance:

• Optical revenue, full-year 2026: up "more than 4x" vs 2025.

• Optical revenue, 2027: driven by the ramp of single-lane 100G products, up "more than 3x again" vs 2026.

• Q3: Overall revenue to "continue growing steadily" (no specific figure given).

"More than 4x" and "more than 3x" are strong, target-style language, tied to a clear product milestone (single-lane 100G ramp), meaning this isn't feel-good vision but backed by a shipment schedule. By contrast, the Q3 outlook used conservative wording like "steady growth" without numbers — which usually means the near term is still on the rhythm of existing businesses, with the optical inflection drawn further out.

In other words, Airoha clearly separates "today's cash flow" from "tomorrow's upside": today is stabilized by earbuds and networking, while the upside rests entirely on multiples of optical growth. Whether those multiples materialize depends not on demand but on how gross margin is split across the optical module supply chain — exactly the question we try to answer in 800G vs 1.6T Optical Modules: A BOM Teardown of Who Really Captures the Margin.

5. Supply Chain and Customer Clues

Airoha didn't name customers, but a few clues are worth noting. First, bringing 10G-PON into data center OOB with a "save 99% of management rack space" pitch targets hyperscalers and white-box switch makers, not traditional telcos — meaning Airoha is trying to get onto AI infrastructure procurement lists. Second, optical SerDes follows the pluggable route, so customers will be module makers; Airoha sells "the electrical chip inside the module," positioning in the component supply chain rather than making modules itself.

The source of this wave of optical demand is the ever-rising AI capital expenditure (capex). The industry's decisive point is shifting from the "demand side" to the "supply side" — who can mass-produce and who can deliver reliably. We laid out the full context of this shift in our industry weekly After the $725B Capex Is Locked In, Optical Communications' Decisive Battle Has Moved to the Supply Side. Whether Airoha captures this wave depends on whether its SerDes and PON chips can ramp on time and reliably.

6. Conclusion

Airoha delivered a report that is "steady enough now, bold enough for the future": record revenue, gross margin held above 50%, profit jumping in step, while clearly staking its growth story on optics growing 4x in 2026 and another 3x in 2027. It chose the most pragmatic pluggable + SerDes route — get paid first, then talk CPO.

Three metrics to track next: First, optical revenue share — management previously guided that optics plus Ethernet could together approach 20% of revenue; how much this rises each quarter is the thermometer for the growth story; Second, whether gross margin holds above 50% — new product ramps often compress margins first, and whether Airoha can ramp while maintaining profitability decides the quality of this growth; Third, the single-lane 100G volume production schedule — this is the fuse for the 2027 "another 3x" promise; if the schedule slips, the whole valuation narrative has to be recalculated.

In one sentence: Airoha hasn't made big money from optics yet, but it has already convinced the market to redefine it from an "earbud and networking chip maker" into an "entrant in AI optical interconnect" — and the earnings numbers just handed this story its first ticket.
