SiriusXM Holdings shares gained as much as 6.3% intraday after Deutsche Bank upgraded the stock to Buy from Hold and raised its price target to $45 from $31; an earlier account put the session gain at 5.5% to $29.12. The target represented 63% upside from Tuesday’s close. Deutsche Bank cited improved digital audio advertising prospects and stable subscription revenue, with analyst Bryan Kraft saying Wall Street has overlooked SiriusXM’s potential in 2027 and 2028. The company is preparing to become Alphabet’s exclusive U.S. audio advertising representative, a partnership Deutsche Bank estimates could add $2 billion in annual revenue by 2029 at a high-teens EBITDA margin, contributing $350 million to $400 million in EBITDA. SiriusXM’s expanded Amazon partnership could provide additional support. Berkshire Hathaway’s 37% stake could exceed 50% after roughly $2.5 billion in buybacks at the current share price, creating an ownership uncertainty Kraft said does not undermine the investment case. The recommendation remains more bullish than the broader analyst consensus, with LSEG data showing eight Holds and only four Buy or Strong Buy ratings among 16 analysts; shares are up 38% year to date.
