Sonos heads into its fiscal Q2 earnings report on May 6 with two sharply contrasting signals pulling in opposite directions: a 10% activist stake that has been buying aggressively for months, and a short interest position that just jumped nearly 18% in a single week.
The ownership story is hard to ignore. Coliseum Capital Management, a 10% holder, spent over $47 million building its position between mid-February and mid-March — more than 3.1 million net shares added in 90 days at prices averaging around $13.50–$15.59. That cluster of buying into weakness looks like high-conviction value accumulation. Coliseum now holds roughly 15% of shares outstanding, making it the company's largest declared holder, just ahead of BlackRock's near-identical 14.9% stake.
Short sellers have pushed back hard, however. Short Interest as a percentage of the free float climbed to 9.8% — up from roughly 8.3% a week earlier — the sharpest weekly increase in months. The jump came almost entirely in the final week of April, after SI had briefly dipped to around 8.3% in mid-April. Borrowing remains inexpensive at 0.57%, and availability is loose, meaning new shorts face no friction entering the trade. The ORTEX short score has also drifted higher, reaching 56.1 from the low 50s in mid-April, suggesting the short community is quietly adding pressure ahead of the print.
Options tell a third story: call positioning dominates. The put/call ratio is running below its 20-day average at 0.35, roughly one standard deviation below the recent mean, meaning demand for upside calls outweighs puts by a wider margin than usual. That reflects a market leaning toward recovery — consistent with a stock up 9.5% over the past month to $14.87, even as the YTD return remains negative at roughly -15%. Analyst consensus, based on the most recent data from late April, sits at a mean price target of $19.13, implying meaningful upside from current levels, with most coverage maintaining Buy-equivalent ratings.
The bull case rests on improving margins, ecosystem lock-in — 61% of users averaging nearly 4.5 Sonos products per home — and evidence that cost discipline is taking hold. Bulls point to EBITDA margins above 20% and net cash of over $300 million. Bears focus on revenue: Q2 last year saw a 0.9% year-on-year revenue decline, with no major product catalyst on the immediate horizon, and questions linger over ongoing patent litigation costs. The stock's last post-earnings reaction, in early March, was a 6.9% drop on the day followed by a further 10% over five days — a result that still casts a shadow over sentiment.
The print tomorrow will test whether Coliseum's sustained buying thesis is validated by a revenue recovery, or whether short sellers are right that the near-term product pipeline leaves growth too thin to support the stock's recent bounce.
