The AI Boom Has a Second Act—And It's Playing Out in Optics

Ciena (NYSE:CIEN) reported record fiscal third-quarter 2026 results, with revenue, operating margin and adjusted earnings per share reaching new highs as demand for optical networking equipment accelerated across data-center and wide-area network applications.

Revenue for the quarter was $1.67 billion, up 37% from a year earlier and at the top end of the company's guidance. Adjusted operating margin reached 22.5%, more than double the year-ago level and above guidance, while adjusted earnings per share rose 215% year over year to a record $2.11.

President and CEO Gary Smith said the performance came amid "an extraordinary industry demand environment" tied to investment in data-center infrastructure and artificial intelligence. He said AI workloads are increasing requirements for high-speed, low-latency optical connectivity both between and within data centers.

Backlog Climbs as Orders Outpace Revenue

Ciena exited the quarter with backlog of $8.5 billion, an $800 million sequential increase. The company's book-to-bill ratio was significantly above one during the quarter, and management said it expects backlog to rise at a faster rate in the fiscal fourth quarter.

Smith said that, one month into the fourth quarter, Ciena had booked nearly as much demand as it received during the entire third quarter. The company expects to finish fiscal 2026 with more than $10 billion in backlog, extending into fiscal 2028.

Management attributed the elevated backlog primarily to lead times and supply limitations rather than weaker conversion of demand. Executive Advisor Scott McFeely said the "vast majority" of the expected $10 billion backlog carries customer-requested delivery dates in 2027, and that the backlog covers most of the company's preliminary 2027 revenue outlook.

Chief Financial Officer Marc Graff said industry capacity will need to expand substantially to balance supply and demand. He said Ciena does not expect that balance to be restored before 2028.

Smith said approximately half of Ciena's business now comes directly from hyperscalers. He added that so-called "neo scalers" are becoming more active in networking investment, including through fiber deployment and network agreements, particularly in the U.S. and international markets.

Optical Portfolio Drives Growth

Ciena said combined optical networks revenue, including interconnects, increased more than 45% year over year. Revenue from its RLS optical line systems and Waveserver systems each grew more than 55%, while interconnects revenue more than doubled. Direct cloud-provider revenue climbed more than 80%.

The company said its in-and-around-data-center revenue has quadrupled year to date, exceeding its prior goal of tripling that business. Two customers each accounted for more than 10% of third-quarter revenue.

Smith said adoption of the company's WaveLogic 6 Extreme platform, which he described as the only 1.6-terabit high-performance modem currently on the market, has exceeded the ramp of the prior WaveLogic 5 Extreme generation. Ciena also shipped more than twice as many 800 ZR pluggable optics in the third quarter as it did in the prior quarter.

The company expects initial customer standardization of its HyperRail next-generation line-system product by the end of 2026, followed by material revenue scaling through 2027. Graff said HyperRail revenue could reach several hundred million dollars in 2027, though the pace could be faster if more components were available. He said the product is expected to carry better economics than the company's existing RLS offerings and be accretive to overall margins as it ramps.

Ciena also said it received sample orders from several anchor customers for Vesta, its open co-packaged optics solution. Management expects revenue from that product to begin in 2027 and ramp into 2028.

Margins, Supply Investments and Customer Pricing

Adjusted gross margin was 46.4% in the third quarter, including roughly 70 basis points of benefit from tariff refunds. Graff said gross margin would have reached the top end of guidance even without that benefit, citing product mix, pricing discipline and execution.

The company generated $116 million of free cash flow during the quarter while investing in working capital to support inventories and revenue growth. Ciena ended the quarter with $2.8 billion in cash and equivalents.

Graff said Ciena has finalized long-term supply agreements for certain key components through 2029, including incremental capacity intended to support customer demand. The company expects its investments under those agreements to reduce cash from operations in the fiscal fourth quarter.

In discussions with customers, Graff said Ciena has negotiated price increases ranging from high-single-digit percentages to high-teens or low-20% levels, depending on customer and product line. Some of those increases will apply selectively to existing backlog, he said. The negotiations also include payment terms, fill rates and reciprocal commitments intended to improve supply security for both Ciena and its customers.

Graff said tariffs are generally neutral to margins because the company passes tariff costs through to customers. He noted that the third-quarter refund benefit was a one-time accounting adjustment and said Ciena is evaluating potential effects from Canada's tariff regime, which could amount to about $10 million per quarter before mitigation efforts.

Fourth-Quarter and 2027 Outlook

For fiscal fourth-quarter 2026, Ciena forecast revenue of $1.75 billion, plus or minus $50 million. It projected adjusted gross margin of 45%, plus or minus 50 basis points, and adjusted operating expenses of about $415 million, plus or minus $10 million. The company expects adjusted operating margin of approximately 20%, plus or minus 50 basis points.

The outlook raises Ciena's full-year revenue midpoint to $6.42 billion and calls for full-year adjusted operating margin between 20% and 21%, which would exceed 20% for the first time in company history. Ciena also expects to increase its market share in the combined optical systems and pluggable optics market by about four percentage points to roughly 30%.

Looking ahead, management provided an early view that fiscal 2027 revenue will grow at least 30% year over year to $8.3 billion to $8.4 billion, with potential upside dependent on component supply. Ciena expects 2027 gross margin of at least 45% to 46% and adjusted operating margin between 25% and 27%.

Smith said the company believes its addressable market could expand from about $25 billion currently to about $50 billion by 2029 as AI-related networking requirements expand. He said Ciena remains in the early stages of a multiyear investment cycle involving data-center interconnection, distributed AI training, inference traffic and broader network upgrades.
