EBITDA per Share: Operating Cash Proxy per Share

Key Takeaways

• EBITDA per share equals EBITDA divided by diluted shares outstanding, useful for capital-intensive firms with heavy depreciation.
• Damodaran's EV/EBITDA framework is the most common enterprise multiple, especially across leverage profiles.
• EBITDA ignores capital intensity, so per-share EBITDA can flatter firms that need continuous reinvestment.
• Compare EBITDA per share to capex per share; the gap shows whether reported profitability survives reinvestment.

What It Is

EBITDA per share measures non-GAAP operating profit before interest, taxes, depreciation, and amortization, divided by diluted shares outstanding. EBITDA is widely used as a rough proxy for operating cash generation because it strips out non-cash depreciation and amortization and ignores the financing decision captured in interest expense.

The CFA Institute curriculum classifies EBITDA-based multiples as enterprise value multiples, since EBITDA accrues to all capital providers. The per-share version is a translation tool, not a primary equity-valuation input.

The Intuition

Two firms in the same industry may have very different debt loads and very different depreciation schedules. EBITDA strips both effects out, so the operating profitability of one can be compared to the other on equal terms. Per-share scaling then makes comparisons sensible across firms of different sizes.

Damodaran identifies EV/EBITDA as the most common enterprise-level valuation multiple precisely because it neutralizes capital-structure differences and accounting choices around useful lives. The per-share version inherits those advantages.

How It Works

The formula is:

EBITDA = Operating Income + Depreciation + Amortization
EBITDA per Share = EBITDA / Diluted Shares Outstanding

Operating income here is reported operating profit, before interest income and expense. Some practitioners add back stock-based compensation; this is an adjusted EBITDA that the CFA curriculum and most academic texts warn against because share-based compensation is a real cost paid in dilution.

Two practical points. First, use diluted shares for consistency with EPS reporting. Second, the link to enterprise value is direct: if EV per share equals price plus debt per share minus cash per share, then EV per share divided by EBITDA per share equals the company-level EV/EBITDA multiple.

Worked Example

A cable infrastructure company reports operating income of $4.8 billion, depreciation of $2.4 billion, and amortization of $300 million. Diluted shares outstanding are 1.5 billion.

EBITDA = 4,800 + 2,400 + 300 = $7,500 million
EBITDA per Share = 7,500 / 1,500 = $5.00

If the stock trades at $50, and the firm carries $4 of debt per share and $1 of cash per share, the EV per share is 50 + 4 - 1 = $53. The EV/EBITDA multiple is 53 / 5.00, or 10.6.

Capital expenditures run at $3.2 billion, or $2.13 per share. EBITDA minus capex per share is 5.00 minus 2.13, or $2.87. That is much closer to real free cash flow per share than the headline EBITDA figure. The firm's reported EBITDA per share of $5.00 implies a 4.5x reinvestment-adjusted multiple in this case (53 / 2.87 is approximately 18.5), well above the 10.6 headline. Damodaran's reinvestment adjustment in EV/EBITDA work captures this distinction.

Common Mistakes

1. Treating EBITDA as cash flow. EBITDA ignores working capital, taxes, capex, and interest. It is not free cash flow and should not be treated as one.
2. Per-share comparisons across different capital structures. A highly levered firm and a debt-free firm can show identical EBITDA per share but very different equity values. Compare on EV per share, not just price.
3. Using adjusted EBITDA without scrutiny. Add-backs for restructuring, transaction costs, and share-based compensation can inflate EBITDA per share by 20% or more. Always reconcile to GAAP operating income.
4. Ignoring capex. A high EBITDA per share in a capital-intensive business is often offset by equally high capex per share. The metric is more useful in asset-light businesses where reinvestment is low.
5. Forgetting the EV bridge. EBITDA per share matters most when paired with EV per share. Comparing price to EBITDA per share without adjusting for debt and cash distorts the multiple.

Frequently Asked Questions

What is EBITDA per share in simple terms? It is EBITDA divided by the number of shares. A figure of $5 means each share is backed by $5 of pre-interest, pre-tax, pre-depreciation operating profit.

How does EBITDA per share affect investment decisions? It supports cross-firm comparisons in capital-intensive industries such as telecom, cable, utilities, and energy, where depreciation differences make EPS hard to compare. It also bridges to EV/EBITDA, the most-quoted enterprise multiple.

What is a real-world example of EBITDA per share? Large US telecom and cable firms have reported EBITDA per share between $3 and $15 in recent years, with EV/EBITDA multiples typically in the 6x to 10x range.

How can investors use EBITDA per share effectively? Compute capex per share alongside it, then subtract. The resulting EBITDA-minus-capex per share is a quick proxy for unlevered cash generation. Compare across peers, not in isolation.

How is EBITDA per share different from EPS? EPS captures net income after interest, taxes, depreciation, and amortization. EBITDA per share adds all four back. EBITDA per share is always larger than EPS for any solvent firm.
