To determine the appropriate extent to which VERBUND AG should rely on hybrid bonds in its capital structure, we must analyze the company's financial health, risk profile, market conditions, and the specific characteristics of hybrid instruments.

**1. Financial Health and Capital Structure Analysis:**
*   **Strong Profitability and Cash Flow:** VERBUND reported a significant increase in Revenue (from ~4.78B EUR to ~10.35B EUR) and Profit Loss Attributable to Owners (from ~874M EUR to ~1.72B EUR) in 2022. EBITDA more than doubled to ~3.16B EUR. Operating cash flows were strong at ~2.02B EUR. This indicates a robust ability to service debt.
*   **Low Leverage:** Looking at the balance sheet for 2023-01-01:
    *   Total Equity: ~8.32B EUR.
    *   Total Liabilities: Assets (19.16B) - Equity (8.32B) = ~10.84B EUR.
    *   Financial Liabilities (Current + Noncurrent): ~1.11B + ~2.84B = ~3.95B EUR.
    *   The ratio of Financial Debt to Equity is roughly 0.47, which is conservative for a utility company.
    *   The Equity ratio is ~43% (8.32/19.16), which is quite healthy.
*   **Credit Quality:** The strong earnings, low leverage, and regulated/semi-regulated nature of the business (grid revenue, electricity sales) suggest a high credit rating (likely Investment Grade, potentially A-range).

**2. Market Conditions (2022):**
*   **Rising Interest Rates:** The swap curves show a dramatic shift from negative rates in 2020/2021 to positive rates in 2022 (e.g., 10Y Swap average rose from 0.053% to 1.927%). The iShares Core Euro Corp Bond yield also rose.
*   **Cost of Capital:** In a rising rate environment, the cost of debt increases. Hybrid bonds typically offer a higher coupon than senior debt because they are subordinated and often have equity-like features (deferrable coupons). However, they are treated as equity for regulatory capital purposes (if they meet specific criteria) or mezzanine capital.
*   **Investor Appetite:** The "Bear" case yields are significantly higher, indicating market volatility and risk aversion. Investors demand higher premiums for subordinated risk.

**3. Role of Hybrid Bonds:**
*   **Purpose:** Hybrids are primarily used to optimize the weighted average cost of capital (WACC) while maintaining credit ratings. They provide equity credit (usually 50-100% depending on the rating agency) without diluting existing shareholders.
*   **Suitability for VERBUND:**
    *   VERBUND already has a strong equity base.
    *   It has low financial leverage.
    *   It generates substantial cash flow.
    *   There is no immediate distress or need for massive capital injection that would require the equity-like buffer of hybrids to protect senior creditors.
    *   Issuing hybrids in a rising rate environment (2022) is expensive compared to the previous low-rate era. The coupon on hybrids would be significantly higher than senior debt.
    *   Given the strong investment grade profile, VERBUND can access senior unsecured debt markets at relatively favorable rates compared to hybrids.

**4. Strategic Consideration:**
*   **0%:** Relying 0% on hybrids is a valid strategy for companies with very strong equity buffers and low leverage, as it avoids the complexity and higher cost of hybrid instruments. VERBUND's equity ratio is healthy.
*   **25%:** A small allocation might be used for fine-tuning capital structure or extending duration, but given the low existing debt load, it's not strictly necessary.
*   **50%+:** High reliance on hybrids is typical for companies with higher leverage, lower credit ratings, or those needing to shore up equity ratios without issuing common stock. VERBUND does not fit this profile.

**Conclusion:**
VERBUND AG is a financially robust utility with low leverage, strong cash flows, and a high credit quality. In the 2022 environment of rising interest rates, the cost of issuing hybrid bonds (which carry a risk premium over senior debt) is less attractive. The company does not exhibit the financial distress or high leverage characteristics that typically drive a significant reliance on hybrid capital. Its current capital structure is well-balanced with a strong equity base. Therefore, there is little strategic imperative to introduce or heavily rely on hybrid bonds. A conservative approach, minimizing complex and expensive subordinated debt in favor of senior debt and equity, is most appropriate. Among the choices, 0% reflects a strategy of maintaining a simple, low-cost capital structure given the company's strength. However, many large utilities do maintain *some* hybrid issuance for portfolio diversity and rating agency optimization. But looking at the *extent* it *should* rely on them: given the low debt-to-equity, the need is minimal. If forced to choose a level of *reliance*, 0% or 25% are the contenders. Given the specific prompt asks "to what extent... rely", and the company is in a strong position to use cheaper senior debt or internal cash, the reliance should be minimal to none. However, in corporate finance practice, even strong IG issuers often have *some* hybrids. Let's look closer. The question asks for the extent of *reliance*. With a Debt/Equity of < 0.5, the company is under-levered by utility standards. It could take on more debt. But hybrids are expensive. Senior debt is cheaper. So it should rely on Senior Debt, not Hybrids. Thus, reliance on Hybrids should be low. 0% is the most distinct answer for "no need for this specific expensive instrument".

Let's re-evaluate 25%. Is there a case for 25%? Some utilities target a specific mix. But VERBUND's balance sheet is very clean. The "Bear" market data shows high volatility. Hybrids are sensitive to interest rate spikes. Issuing them in 2022 would lock in higher rates. The company has plenty of equity. It doesn't *need* the equity credit from hybrids to maintain its rating. Therefore, it should not *rely* on them.
