Cubex Tubings up 10.25% as board approves Rs 75 crore warrant issue to fund vacuum-melting furnace

In a filing dated 14 October 2026, the board of Cubex Tubings Limited approved a fundraise of up to Rs 75.00 cr through a preferential issue of convertible warrants.

According to the outcome of the board meeting on page 1 of the filing:

• The company will issue up to 50,00,000 Convertible Warrants into Equity Shares of face value Rs 10 each.
• The issue price is Rs 150 per warrant, including a premium of Rs 140.
• The issue will be made to "identified investors / eligible investors" on a private placement basis, subject to shareholder, stock exchange and regulatory approvals.

Annexure I on page 2 reiterates that the issue size is "up to 50,00,000 Convertible Warrants in to Equity Shares at Rs. 150/- each, aggregating up to Rs 75.00 cr".

The warrants are convertible within 18 months from the date of allotment, as per Annexure III on page 5. Investors must pay 25 % upfront and the balance 75 % within 18 months; if they do not exercise, the amount paid will be forfeited.

The key to why the stock moved lies in how Cubex plans to use the money.

On page 3, under "Purpose and use of funds", the company states that it proposes to utilise the proceeds for:

"the procurement and installation of a vacuum melting furnace at its new manufacturing facility, including (Land, Civil & Electrical works, and other balancing equipment) for nuclear, electrical manufacturing of specialized products, aerospace, defence, oil and gas, and other heavy engineering industries for ferrous-based (Special steels -titanium and its alloys, nickel-based, chrome-based etc.) and non-ferrous (oxygen-free copper, Beryllium copper, zirconium/chrome alloys, etc.)."

The filing further notes that Cubex already has the downstream processing equipment required for these products, and that the proposed furnace will "complement the existing equipment and strengthen the Company’s manufacturing capabilities".

Crucially, the company states that "100 % of the issue proceeds will be utilized for this" project. That clarity on deployment — and the focus on higher-spec, higher-value alloys — is what the market appears to be rewarding.

The live market read highlights another important factor behind the rally: substantial promoter participation.

Annexure II on page 4 lists five proposed investors and their indicative holdings:

• Cubex Securities Ltd (promoter) is slated for 33,90,000 warrants with an investment of Rs 50.85 cr.
• Four non-promoter investors — Ajeet Modi, H & A Unicorns, Ruchas Ventures and Payal Tandan Shrivastava — together account for the remaining warrants and investments as detailed in the table.

The indicative shareholding table on the same page shows that Cubex Securities Ltd’s holding would rise from 18,67,395 shares (13.04%) before the issue to 52,57,395 shares (28.00%) after full conversion of warrants.

At the broader level (page 5), the "Indicative capital and category shareholding" table shows:

• Promoter and promoter group: from 63,60,304 and 44.42 % before the issue to 97,50,304 and 50.47 % after full conversion.
• Public: from 79,58,671 and 55. 58 % to 95,68,671 and 49.53 %.
• Total equity shares: from 1,43,18,975 and 100.00 % to 1,93,18,975 and 100%.

This structure means two things the market is likely focusing on:

1. Promoters are putting in significant capital at Rs 150 per warrant, signalling confidence in the long-term value of the expansion.
2. While there is clear dilution — total equity shares rising from 1,43,18,975 to 1,93,18,975 on full conversion — the promoter group’s stake increases above 50%, tightening control and aligning them more closely with future performance.

The filing notes on page 2 that a registered valuer, Saksham Valuer Private Limited, arrived at a price of Rs. 142.31, and that "the Board Proposed to issue the same at Rs. 150/-".

That means the preferential issue is priced above the valuer’s number, not at a steep discount. For existing shareholders, this can be seen as less dilutive than a deep-discount issue, and it reinforces the message that insiders are willing to commit money at a relatively full price.

With the stock last traded at Rs 211, the market is clearly assigning a premium to the company’s future earnings potential if the vacuum melting furnace project delivers on its promise in nuclear, aerospace, defence, oil and gas and other heavy engineering segments.

The company has laid out an indicative timetable and conditions:

• As per Annexure I, the issue is subject to approval of the members and the stock exchanges, and the warrants are to be allotted within 15 days from the date of receipt of In-Principle Approval.
• The relevant date for pricing is 7" Oct 2026, and the company notes that there will be no change in control.

However, there are several aspects the filing does not disclose:

• No revenue, profit or margin numbers are provided in this document; it is purely a corporate action filing.
• There is no quantified guidance on expected returns from the furnace investment, payback period or targeted capacity utilisation.
• The filing does not break out any projected impact on earnings per share post-dilution.

Putting it together, the 10.2% rise in Cubex Tubings, with the stock changing hands at Rs 211, appears to be driven by a combination of:

• A clearly articulated Rs 75.00 cr capex plan into a vacuum melting furnace aimed at higher-margin, specialised alloys.
• Strong promoter participation via 33,90,000 warrants and a potential increase in promoter holding to 50.47 % of equity on full conversion.
• Preferential pricing at Rs 150 per warrant, above the valuer’s Rs. 142.31, which may be viewed as a vote of confidence rather than opportunistic cheap capital.

The actual payoff will depend on execution, regulatory approvals and how quickly Cubex can ramp up orders in nuclear, aerospace, defence and other targeted sectors. For now, the market is marking up the stock on the promise of a more technologically advanced, higher-value product mix funded by committed insiders.
