Warner Bros. Discovery (NASDAQ:WBD) reached sixth place on Monday's most-active list not on a surprise headline but on the final mechanics of a deal that has been months in the making. More than 435 million shares traded, about 5.35 times the stock's normal volume, yet the price barely moved, finishing up three cents at $30.95. That combination, enormous turnover with a flat line, is the signature of a company that is about to stop existing as a public stock.

What's driving the volume

On September 30, Paramount Skydance and Warner Bros. Discovery announced that they expect their merger to close on Tuesday, October 6. Under the merger agreement signed in February, each WBD share converts into $31.00 in cash plus a daily "ticking fee" of roughly $0.0028 that began accruing on September 30. If the deal closes on schedule, holders receive about $31.017 per share. Monday's close of $30.95 therefore sat only about seven cents below the expected payout, a gap of roughly 0.2% that reflects the small remaining risk of a delay and the time value of money over a single day.

The volume spike has a clear index explanation. On October 1, S&P Dow Jones Indices said Twilio (NYSE:TWLO) would replace Warner Bros. Discovery in the S&P 500 effective prior to the opening of trading on Tuesday, October 6, noting that S&P 500 constituent Paramount Skydance was acquiring WBD in a deal expected to be completed soon.

Funds that track the S&P 500 generally need to exit a deleted stock at or near the last close before the change takes effect, which in this case was Monday's session. Nasdaq separately announced that Moderna (NASDAQ:MRNA) would replace WBD in the Nasdaq-100 effective October 9, and the company will also be removed from MSCI and other S&P indexes. Put together, a large wave of passive selling met merger-arbitrage buyers who were happy to collect the last sliver of spread, producing heavy volume at an almost unchanged price.

The road to this point was long. Netflix (NASDAQ:NFLX) originally emerged as the leading bidder in December 2025 with an offer for WBD's streaming and studios business, but it walked away in late February after Paramount raised its bid for the whole company to $31 a share in cash, valuing the transaction at roughly $110.9 billion. WBD shareholders approved the merger in April, the Justice Department cleared it in June, and European and UK regulators followed over the summer.

The final obstacle was a lawsuit by a coalition of state attorneys general led by California. Those states settled on September 21, and on September 30 U.S. District Judge Araceli Martinez-Olguin approved the agreement. The five-year settlement requires the combined company to release 30 theatrical films a year in the U.S., to negotiate cable carriage separately for Warner and Paramount channels, and to set up a five-member panel overseeing editorial independence at CNN and CBS.

The business

Warner Bros. Discovery owns the Warner Bros. film and television studios, HBO and the HBO Max streaming service, DC Studios, CNN, and a large portfolio of cable networks including TNT, TBS, Discovery, and Food Network. After closing, those Assets will sit inside a combined company led by David Ellison as chairman and CEO, with former Mattel (NASDAQ:MAT) chief Ynon Kreiz as co-CEO. HBO's Casey Bloys and CBS's George Cheeks are slated to co-chair content, while James Gunn and Peter Safran continue to run DC Studios. S&P also noted that Paramount Skydance plans to move its primary listing to the New York Stock Exchange after the merger.

Recent results and guidance

WBD's most recent quarter illustrated why a sale at a fixed cash price appealed to many shareholders. Second-quarter 2026 revenue was $8.7 billion, down 12% excluding currency effects. Streaming was the bright spot, with segment revenue up 10% to about $3.08 billion. The traditional businesses were weak: Global Linear Networks revenue fell 17% to just under $4.0 billion, and Studios revenue dropped 39% to about $2.33 billion against a tough comparison.

The company said the loss of NBA rights reduced its Advertising growth rate by 20 percentage points. Adjusted EBITDA slipped 6% to $1.88 billion, free Cash Flow fell 19% to $572 million, and the company ended the quarter with $33.1 billion of gross debt against $3.4 billion of cash. As a company with a pending sale, WBD did not offer the kind of forward outlook that would matter to shareholders now.

Valuation

Traditional valuation metrics have little meaning at this stage. WBD's trailing Earnings are negative, with diluted EPS of minus $1.27 and no meaningful P/E, and its $77.71 billion Market Value is simply the cash deal price multiplied by the share count. The stock trades as a short-dated cash claim, not as a media business. On September 29, research firm Argus downgraded the shares to Sell, citing limited upside after the $31 offer and forecasting a 2026 loss of $0.90 per share, a move that underlines how little room remains above the deal price.

Bull case

For holders who stay in until closing, the arithmetic is straightforward. They should receive slightly more than Monday's close in cash, with the ticking fee adding a fraction of a cent for each additional day if closing slips. All major regulatory approvals are in hand, the state lawsuit has been settled with court approval, and both companies have publicly named October 6 as the target date. Investors who wanted continuing exposure to the Warner Bros. library, HBO, and DC can instead look at Paramount Skydance, which will own those assets.

Bear case

The upside is capped at roughly seven cents per share, so the risk-reward for a new buyer is thin. Both companies have described the closing date as anticipated rather than guaranteed, and it remains subject to customary closing conditions. Any last-minute delay would tie up Capital for a tiny return. Beyond the deal, WBD's underlying Business showed shrinking linear TV revenue, volatile studio results, and a heavy debt load, all of which now become Paramount Skydance's problem, along with critics' concerns about media consolidation that Senator Elizabeth Warren called a disastrous outcome.

The final trading day and the handoff to Paramount Skydance

The key item is confirmation that the merger closed on October 6 and that WBD shares have stopped trading, followed by the cash payment to shareholders through their brokers. Index changes continue to ripple through the market: Twilio enters the S&P 500 on Tuesday, Formfactor (NASDAQ:FORM) and Workiva (NYSE:WK) move up in the S&P MidCap 400 and SmallCap 600 as part of the same reshuffle, and Moderna joins the Nasdaq-100 on October 9. After that, attention shifts to Paramount Skydance's first results as a combined company, its plans for HBO Max and Paramount+, progress on integration costs and debt reduction, and how its Leadership team handles the editorial-independence commitments made to the states.
