Dolby beats on earnings, buys video patents, expands Meta deal; short seller warns on AI costs

Earnings beat and strong guidance lift Dolby shares Dolby's fiscal Q3 revenue of $305 million missed estimates, but earnings per share of $0.69 beat the $0.67 expected. Management guided Q4 revenue to $362–392 million and full-year revenue to at least $1.4 billion. Investors focused on the profit beat and upbeat outlook, sending the stock up 11.7%.
This is the period's biggest price-moving event and shows profit strength despite a sales miss.
Dolby buys 250 video-compression patents Dolby acquired a portfolio of 683 intellectual property assets, including 250 granted patents, from Florida Atlantic University and OP Solutions. The technology helped create the H.266 video standard, and some patents are already licensed through a patent pool. This strengthens Dolby's long-term technology and licensing position.
It expands Dolby's patent base and future licensing revenue potential, a core part of its business.
Hedge fund shorts Dolby on AI cost pressure Prosper Stars & Stripes disclosed a short position in Dolby, arguing that AI-driven memory chip cost inflation will raise consumer electronics prices and hurt back-to-school and holiday demand. It also expects Dolby's forecasts to prove too optimistic. This creates a real counterweight to the positive news.
It is the main bearish force this period and explains why the stock still faces skepticism.
Meta expands Dolby Atmos and Vision across its ecosystem Meta will put Dolby Atmos audio capture in its AI glasses and bring Dolby Vision and Atmos to Instagram and its next VR headset. This embeds Dolby's formats into one of the world's largest consumer platforms, broadening adoption beyond cinema and home entertainment and supporting future licensing revenue.
It is a major new demand driver that extends Dolby's reach into everyday devices and social media.

Ronbay Swings to Profit, Expands Sodium-Ion Capacity

First-half profit turnaround Ronbay returned to profit with 109 million yuan net income, versus a loss last year, as revenue rose 39.57% on higher shipments and better overseas plant use. This shows the core business is recovering, which supports the stock price.
This is the key financial result that directly improves investor confidence and valuation.
Sodium-ion cathode expansion Ronbay plans to invest 4.723 billion yuan in a 300,000-tonne sodium-ion cathode plant, with first phase starting August 2026. Sodium-ion products are already shipping at scale, positioning the company for future growth beyond lithium.
This major investment signals a new growth engine and long-term capacity leadership.
Lithium manganese iron phosphate full production The company's LMFP business is running at full capacity with all output sold, and sales rose about 50% year-on-year. This high-demand product line boosts revenue and shows strong market acceptance.
It highlights a key product driving current sales and profitability.
Industry-wide capacity expansion risk Rising material prices have triggered about 30 billion yuan of new projects across the battery supply chain, including Ronbay's. While this meets current demand, it could lead to oversupply and margin pressure later, a risk to watch.
It provides a balanced view of the competitive and pricing risks from collective expansion.
