Sonova’s Strategic Share Buyback: A Shrewd Move to Boost Shareholder Value?

Sonova Holding AG, the global leader in hearing care solutions, has concluded its three-year share buyback program—a $419.8 million initiative that marked another chapter in its long-standing strategy to optimize capital structure and enhance shareholder returns. The program, which ran from April 2022 to April 2025, repurchased 1.53 million shares, or 2.4% of its outstanding capital, at an average price of CHF 273.86 per share. While the move aligns with Sonova’s history of capital discipline, the program’s execution raises critical questions about its effectiveness, future plans, and the broader implications for investors.

The Buyback in Context

Sonova’s buyback program, announced in March 2022 with a maximum authorized budget of CHF 1.5 billion, ultimately fell far short of its initial ambition. The CHF 419.8 million spent represents just 28% of the allocated capital, suggesting the company either found shares too expensive to buy in bulk or prioritized other uses for its cash. This contrasts sharply with its 2021-2022 program, which deployed CHF 699 million—more than double the latest effort.

The decision to repurchase shares for capital reduction, a process that permanently reduces the number of outstanding shares, is a deliberate move to boost earnings per share (EPS) and potentially increase shareholder value. By trimming shares from 62.7 million to 59.8 million, Sonova has tightened its equity structure, a strategy that often appeals to investors seeking concentrated ownership.

Market Performance and Tax Considerations

The buyback period coincided with a volatile market for Swiss equities. While Sonova’s share price dipped in late 2022 and early 2023, it rebounded by 2024, closing at CHF 345.50 in April 2025—up 26% from its lowest point in 2023. This suggests the company may have timed purchases strategically, though the average repurchase price of CHF 273.86 remains below the closing price at program’s end.

However, Sonova’s buybacks were not without costs. Swiss tax law imposed a 35% withholding tax on the difference between the repurchase price and the nominal CHF 0.05 value of each share, eating into the program’s net economic impact. This regulatory hurdle underscores the complexity of share repurchases in Switzerland, where companies must balance tax efficiency with shareholder value.

A Strategic Legacy, But What’s Next?

Sonova’s buyback history reveals a pattern of disciplined capital allocation. Since 2007, the company has executed buybacks totaling over CHF 2 billion, including programs in 2018-2021 (CHF 572 million) and 2021-2022. These efforts have steadily reduced its share count, a key driver of its 2.13% dividend yield and stable earnings growth. In its 2023/24 fiscal year, Sonova reported CHF 3.6 billion in sales and CHF 610 million in net profit, underpinning its financial resilience.

Yet the absence of any announced future buybacks post-2025 leaves investors in the dark. Sonova’s April 2025 statement concluded the program with no forward guidance, a notable departure from peers like Microsoft or Apple, which often telegraph future share repurchases. This silence could signal caution amid uncertain macroeconomic conditions or a shift in strategic priorities—such as reinvesting in growth or acquisitions.

Conclusion: A Mixed but Meaningful Move

Sonova’s latest buyback program was a measured, if restrained, success. By repurchasing shares at an average price below its closing value in April 2025, the company likely bolstered EPS and signaled confidence in its long-term prospects. Its 2.4% reduction in outstanding shares, paired with a stable dividend policy, aligns with its role as a defensive stock in the healthcare sector—a sector increasingly valued for its resilience in economic downturns.

However, the underutilized budget and lack of future plans introduce uncertainty. Investors must weigh Sonova’s proven track record of capital efficiency against the risk of stagnation in shareholder returns. With a market cap of CHF 13.46 billion and operations spanning over 100 countries, Sonova remains a pillar of its industry. Yet without clearer signals of future buybacks or growth initiatives, its next chapter hinges on execution in markets where hearing care demand continues to rise—driven by aging populations and technological innovation.

In the end, Sonova’s buyback program was a tactical win, but its legacy will depend on whether the company can sustain its strategic agility in an evolving landscape. For now, shareholders can take comfort in a company that has consistently turned capital discipline into a competitive advantage.
