What caused Gazprom's shares to fall below 100 roubles for the first time since 2009?

Gazprom's shares fell below 100 roubles due to multiple headwinds: Europe's decision to shun Russia's energy over the Ukraine conflict, a decline in oil prices linked to U.S.–Iran talks, Gazprom's failure to secure a new gas deal with China, and negative market sentiment following a Ukrainian drone attack on a Moscow oil refinery owned by Gazprom Neft—the company's oil arm.

How has Gazprom's market value changed compared to its 2008 target, and what is its current valuation?

Gazprom's current market value stands at 2.382 trillion roubles ($32.15 billion), a sharp contrast to the $1 trillion valuation promised by management in 2008; its shares have declined by around a fifth over the past 12 months, and on Monday they hit 99.9 roubles—the lowest level since 2009.
