STMicroelectronics: Data Center Sales Target Nearly Doubles, But Convertible Dilution Sends Shares Lower

STMicro raises data center revenue forecast to $1B by 2026, but new $1.5B convertible bond and dividend schedule trigger dilution, sending shares down 4.7%.

STMicroelectronics delivered a stark lesson in financial complexity on Tuesday, as the stock fell 4.7% to €65.01 even as the company raised its data center revenue forecast to roughly $1 billion for 2026. The contrast between a booming end market and the mechanics of capital structure played out in plain view: a new $1.5 billion convertible bond, alongside a dividend schedule that will see the first quarterly payout on June 24, created a backdrop of dilution and income timing that tempered what should have been a pure growth story.

The convertible issuance is divided into two tranches of at least $500 million each, with five- and seven-year maturities. Settlement is set for June 23, 2026, the same day STMicro will apply for admission to trading on the Frankfurt Stock Exchange’s open market. The company is also calling its existing $750 million zero-coupon convertible due 2027, effectively adding a net $750 million in debt. Market participants often read such moves as a signal that management views the current equity valuation as attractively priced — but the resulting shareholder dilution can weigh on shares in the near term.

On the dividend front, the ex-date falls on June 22, with a payment of $0.09 per share, the first quarterly instalment of the approved annual dividend of $0.36. The payout follows the convertible news and adds another layer of event risk for short-term traders.

The real firepower, however, lies in the data centre ambition. STMicro now expects its data centre revenue to reach about $1 billion in 2026, more than double its earlier projection of “significantly above $500 million.” Management has further hinted at another doubling in 2027 if current momentum holds. The company has introduced new 12V and 6V architectures for 800VDC power delivery, targeting hyperscale customers. This shift is part of a broader portfolio expansion that includes silicon photonics in series production for optical interconnects in AI clusters and a deepening collaboration with Amazon Web Services on connectivity, infrastructure management, and analog components.

Analysts have responded with a flurry of target upgrades. Deutsche Bank lifted its price target from €52 to €75 after the PCIM trade fair in Nuremberg, maintaining a buy rating. Bank of America went further, upgrading the stock to buy with a new target of €86. Goldman Sachs, however, sticks to a hold recommendation, underscoring the split opinion on valuation.

For the second quarter, STMicro guided revenue of $3.45 billion, a sequential increase of 11.6%. First-quarter revenue came in at $3.095 billion, 23% above the prior year, though earnings per share of $0.13 missed the consensus estimate of $0.17. Gross margin stood at 33.8% — ahead of the company’s own target but still far below the 40%-plus peak of the previous cycle.

The technical backdrop reflects the stock’s extreme volatility. After hitting a 52-week high of €70.00 on Monday, shares retreated to €65.01, leaving them 7% below that peak. Year-to-date, the stock has surged roughly 185% (or 178% as of the prior session’s close), placing it 28% above its 50-day moving average and more than 110% above its 200-day average. The 30-day annualized volatility stands at 79%, and the relative strength index of 59.4 suggests elevated but not exhausted momentum. The company’s “Physical AI” narrative — spanning edge intelligence in automotive microcontrollers, sensor integration, and embedded processing — adds a second layer to the story, linking its traditional auto base to the software-defined vehicle transition.

None of that changes the near-term equation. A convertible bond that expands debt by $750 million while retiring existing securities is manageable for a company with $3 billion-plus quarterly revenue, but it forces investors to weigh the cost of dilution against the promise of a structural re-rating. The data centre pivot is credible, but margins need to climb from 33.8% toward 40% to justify the current multiple. STMicro will report second-quarter results on July 23, and that data point will determine whether the market treats the recent pullback as a buying opportunity or a warning.
