Telefon AB L.M. Ericsson Series A vs Ciena: why the prices moved differently

• ▼

  AI-driven memory chip costs to squeeze margins Ericsson warned that rising memory chip costs, caused by competition from AI data centers, will pressure profit margins in late 2026 and 2027. The stock fell 12% in a day. Higher costs mean less profit from each sale, which weighs on the share price.

  This is the biggest negative force on the stock this period, directly hitting profitability.

  Q2 revenue miss and weak networks sales Ericsson's Q2 organic sales fell 1% and reported revenue dropped 6% to SEK 52.7bn, missing estimates. Networks organic sales fell 4% (reported down 8%). This weak demand pushed shares down sharply, as investors worry about growth.

  The revenue miss is the core new financial event that directly caused the stock to drop.

• ▼

  AI boom raises memory chip costs, squeezing margins Ericsson warned that soaring memory semiconductor prices, driven by AI demand, are raising component costs. This will gradually pressure gross margins in coming quarters. The company is taking pricing and cost actions, but the market fears profit erosion.

  This new cost warning explains why the stock fell further and highlights a key future risk.

• ◆

  CEO succession: Per Narvinger to replace Börje Ekholm Ericsson announced that Per Narvinger, head of Networks, will become CEO on October 1, succeeding Börje Ekholm. A leadership change can bring fresh strategy but also uncertainty. The market initially reacted negatively, though the long-term impact is unclear.

  This is a major new corporate event that affects investor confidence and future direction.

  Ciena Sets Ambitious Fiscal 2029 Targets Ciena announced long-term financial targets: ~30% annual revenue growth through 2029, 50% gross margin, and 32-35% operating margin.

  Evercore ISI Upgrades Ciena to Outperform Evercore ISI upgraded Ciena to Outperform with a higher price target, citing its strong position in AI data-center optical connectivity. Analyst upgrades often boost stock prices by increasing investor confidence and attracting new buyers.

  Marvell's Bullish Optical Growth Outlook Lifts Sector Marvell projected the optical interconnect industry to grow 60-70% to $65 billion by 2030, far above Ciena's own 30% outlook. This industry optimism, combined with analyst targets, sent Ciena shares up 14% as investors bet on faster growth.

  Record Q3 Results and Raised Outlook Ciena reported record quarterly revenue of $1.67 billion, up 37%, with adjusted earnings up 215% to $2.11 per share. Management raised full-year 2026 revenue guidance to $6.42 billion and set a preliminary fiscal 2027 target of at least 30% growth, to $8.3–$8.4 billion. This confirms AI-driven demand is translating into real sales and profits, supporting a higher stock price.

  This is the core new event of the period and the main reason CIEN moved, showing the fundamental strength behind the stock.

• ▲

  Backlog Surges Toward $10 Billion Ciena's order backlog rose $800 million to $8.5 billion and is expected to top $10 billion by fiscal year-end. Direct cloud-provider revenue jumped 82% and now makes up 53% of sales. A bigger backlog gives Ciena visibility into future revenue, which supports the stock because it means customers are committing to buy well ahead.

  Backlog growth is a key new metric showing demand strength and future revenue visibility, directly answering why CIEN is moving.

• ▼

  Stock Falls 15% on Margin and Guidance Concerns Despite the earnings beat, Ciena shares dropped 15.2% in a week. The fourth-quarter revenue outlook was only in line with expectations, and adjusted gross margin is expected to ease. Two cloud customers made up 41.7% of revenue, and the stock trades at 35.7 times forward earnings, well above its five-year average of 25.5 times. These factors pressured the stock.

  This explains the sharp negative price reaction and the real counterweight to the strong results, which readers need to understand.

• ◆

  Supply Constraints Limit Growth but Long-Term Deals Secured Ciena secured critical components through 2029, but supply and demand are not expected to balance before fiscal 2028. This limits how quickly backlog turns into revenue, but also means demand outstrips supply, which can support pricing. The company is investing heavily, which will reduce near-term cash flow.

  Supply constraints are a key factor shaping how fast Ciena can grow and are central to the bull-bear debate.

  Record Q2 Results and $7.7B Backlog Ciena reported record Q2 revenue of $1.57B, up 40% year over year, with adjusted EPS nearly quadrupling to $1.64. Backlog hit $7.7B and direct cloud customer revenue jumped 70%, showing strong AI-driven demand for optical networking. Management raised full-year guidance to ~$6.3B.

  This is the core fundamental driver: record results and backlog directly show why CIEN is moving and give investors the big picture.

• ▲

  Quantum-Safe 1.6T Encryption Trial Success Ciena, Quantum Corridor, and Toshiba completed the world's first 1.6 Tb/s quantum-safe optical encryption trial on a live commercial network using Ciena's Waveserver and WaveLogic 6 Extreme. This proves Ciena's technology leadership and opens a new market for secure high-speed networks.

  This is a new technological milestone that differentiates Ciena and could drive future revenue, directly answering why the stock is moving.

• ▲

  Silicon Photonics Market Growth and Nubis Acquisition A new report forecasts rapid growth in silicon photonics through 2036, driven by AI and data centers. Ciena's acquisition of Nubis Communications positions it to benefit from this trend, including 1.6T transceivers and co-packaged optics.

  This shows a long-term industry tailwind and Ciena's strategic move to capture it, supporting the bullish case.

• ▲

  AI Infrastructure Demand Fuels Sector Rally Anthropic's Q2 revenue surge and a Mizuho note on accelerating AI interconnect demand lifted networking stocks, with Ciena up 5.18% on August 17. Institutional 13F filings also showed heavy interest in Ciena, reinforcing confidence in AI-driven demand.

  This captures the latest sector-wide catalyst and institutional interest that directly pushed CIEN higher this period.

• ▲

  S&P 500 Addition and Raised Fiscal 2026 Outlook Fuel Stock Surge Ciena's addition to the S&P 500 and an upgraded fiscal 2026 revenue outlook of ~$6.3B (31% growth) have driven shares up over 77% since inclusion. Argus raised its price target to $650, citing strong Q2 results.
