Flow-Through Shares

TL;DR

Canadian tax instrument letting mining, oil & gas, and clean-energy issuers 'renounce' Canadian Exploration Expense to investors, who deduct it personally.

Flow-Through Shares (FTS) are a uniquely Canadian tax instrument under the Income Tax Act that allow a qualifying corporation (typically mining, oil & gas, and increasingly clean-energy companies) to 'renounce' its Canadian Exploration Expense (CEE) or Canadian Development Expense (CDE) and pass them through to its investors. The investor deducts the renounced expenses on their personal return as if they had directly incurred them — typically generating ~50–60% effective tax savings.

The 2018 Critical Mineral Exploration Tax Credit (CMETC) extended FTS treatment to a defined list of clean-energy minerals (lithium, cobalt, nickel, etc.), reviving the instrument for clean-tech and battery-supply-chain startups. FTS rounds typically clear at premium pricing (10–25% above plain-equity comparables) because the tax shield raises after-tax investor returns.

Worked example

A Sudbury-based critical-minerals junior raises C$10M of FTS at a C$1.20/share price (versus a C$1.00 plain-equity comparable). Investors renounce ~C$10M of CEE under CMETC and claim ~C$5.5M of personal-tax deductions; the issuer's effective cost of capital drops well below comparable equity raises.

Common pitfalls

• Mis-categorising spend as CEE when CRA classifies it as CDE — different deduction rates.
• Failing to renounce within the strict 24-month look-back window.
• Building expectations of FTS premium pricing that the market doesn't actually pay for non-mining issuers.

When this shows up in a pitch deck

Canadian battery and critical-minerals decks state 'C$8M FTS round priced at 18% premium under CMETC' on the round-structure slide.
