Rubico Inc. (RUBI) - What You Need to Know

Rubico is not a tech company. Official paperwork reveals what they actually do, and there are major red flags you must know before buying.

1. What does this company actually do? (The Oil Tanker Twist)

Rubico is a global shipping company. They own two massive, fuel-efficient tankers—the M/T Eco Malibu and M/T Eco West Coast—to transport crude oil. They split off from Top Ships Inc. and started trading in August 2025.

2. How do they make money?

They rent these tankers to oil companies to generate cash. They own just two active ships but are expanding. They are currently building a chemical tanker and a luxury megayacht (the M/Y Sanlorenzo 1150Exp), spending $31 million so far with $7 million left to go.

3. The "All in the Family" Setup

A family trust for businessman Evangelos J. Pistiolis controls Rubico. During the split, this trust received special "Series D" shares that regular investors did not get, granting them super-voting control.

Instead of running the ships directly, Rubico pays a manager called CSI (also run by the family) to handle daily operations. Rubico pays them:

• A daily fee of $670 per ship (rising 2% to 5% annually).
• A 1.25% commission on rental sales.
• A 1% commission on ship purchases or sales.

If Rubico fires CSI, they must give 18 months' notice and pay a massive penalty.

4. What are the major risks?

The paperwork highlights major warning flags:

• Extreme "Watering Down" (Reducing your ownership percentage): Rubico has only 767,786 shares available but is registering 50 million new shares for B. Riley to buy and resell over 36 months. If sold, these will make up 98.5% of the company, severely shrinking your ownership.
• The 3% Discount: B. Riley gets a 3% discount on the stock. They can buy cheap and resell to everyday investors, dragging down the stock's value. B. Riley cannot own over 4.99% at once, but they can repeatedly buy and sell, continuously shrinking your ownership. (Note: B. Riley agreed not to bet against the stock, but others can.)
• The Series G "Trapdoor": Starting April 20, 2026, "Series G" shares can swap into 1.5 million regular shares, nearly doubling the current count. If Rubico sells new shares at a low price, a price-drop penalty triggers. This lowers the swap price, creating even more shares.
• Three Share Merges: Since December 2025, Rubico has merged its shares three times because the price got too low. This is extremely rare for a five-month period and signals severe downward price pressure.
• Zero Outsider Control: The family trust's Series D shares and complex voting rules leave regular investors with virtually no say in company decisions.
• Foreign Loopholes: Based in Greece and incorporated in the Marshall Islands, Rubico bypasses strict U.S. rules. They avoid independent audits of financial controls and operate under laws with fewer shareholder protections.

5. Where does it trade?

• The Exchange and Ticker: Rubico trades on the NASDAQ under the symbol RUBI.
• The Deal: Rubico gets no upfront cash. Instead, they can sell stock to B. Riley over time to raise up to $50 million. This setup is expensive: Rubico must pay a $500,000 sign-up fee and up to $215,000 for B. Riley's legal bills.

The Bottom Line: Rubico is a tiny, family-controlled shipping company. It has a history of merging shares to boost a falling price, massive upcoming share dilution, and a side project building a multi-million dollar megayacht. Unless you love extreme risk, watch this one from the safety of the shore!
