Shares of Officina Stellare (OS.MI) rocketed as much as +22% in a single session after the Italian aerospace-and-defense optics maker won shareholder approval for a stock buyback program and a capital increase of up to €60 million. The twin votes hand management powerful new tools — one to prop up the share price, the other to fund acquisitions — at a moment when the company is still digesting a transformative merger.

  • A Buyback Sends a Confidence Signal, But the Company Is Tiny. Shareholders authorized the purchase and disposal of the company's own shares at the September 14 meeting. A buyback — where a company spends cash to buy its own stock off the market — reduces the number of shares in circulation and can boost the price per share. But in the last 12 months, Officina Stellare earned only €1.34 million in profit on €21.63 million in revenue , meaning any buyback must be modest relative to the stock's soaring price.

  • €60 Million in Fresh Capital Could Double the Balance Sheet — or Dilute Shareholders. The authorized capital increase is enormous for a firm holding just €5.61 million in cash and €14.61 million in debt. If executed, selling new shares would bring in growth capital but would also dilute — or shrink — each existing shareholder's slice of the pie. The funds are intended to support organic growth and acquisitions , a strategy critical after the company completed its merger with Global Aerospace Technologies Group (GATG), finalized via notarial deed in May 2026.

  • The GATG Merger Already Reshaped the Company. Pro forma, the combined group projects €100 million in revenue, €18 million in EBITDA (earnings before interest, taxes, and other non-cash charges), and an order backlog that reached €192 million by May 2026. That backlog provides roughly two years of revenue visibility — a rare luxury for a small-cap. Yet the trailing price-to-earnings ratio sits at 188× , and the enterprise-value-to-EBITDA ratio is roughly 51× — both sky-high even by defense-sector standards.

  • The Stock Has Whipsawed; Next Earnings Will Be the Real Test. After trading near €39 on September 9, shares cratered to €29.70 before this rebound to €34. Officina Stellare's next earnings report is estimated for September 25, 2026 — just days away. That release will reveal whether the merged entity's revenue growth justifies a valuation that now approaches €784 million. Until those numbers arrive, investors are essentially betting on a promise.
