As of December 16, 2025, Kellanova stock is no longer a typical “stock story” — because the equity’s public-market chapter has effectively ended. Mars has completed its acquisition of Kellanova, and each eligible share was converted into the right to receive $83.50 in cash, with trading halted and delisting actions underway. [1]
That doesn’t mean investor interest disappears overnight. It just shifts: from “Will K stock go up?” to “When do shareholders receive cash, what happens to the ticker and filings, and where does snack-sector exposure go now that Kellanova is private?” Here’s the full, up-to-date picture using the latest news, filings, forecasts, and analysis relevant to 16.12.2025.
What happened to Kellanova stock: the $83.50 cash-out is now the reality
The key development for anyone tracking Kellanova shares (formerly NYSE: K) is the closing of the merger on December 11, 2025. In the company’s SEC filing describing the completion, Kellanova states that each outstanding share (with standard exceptions like certain insider-held shares and properly perfected appraisal rights) was “automatically cancelled and converted” into the right to receive $83.50 per share in cash (the “Merger Consideration”). [2]
Just as important for traders: the same filing notes that trading of Kellanova common stock on the NYSE was halted prior to the opening of trading on the closing date. [3]
And from a corporate-status standpoint, this was the true “end of the ticker”: Kellanova became a wholly owned subsidiary in the merger structure described in the filing. [4]
Delisting mechanics: Form 25, potential Form 15, and why quotes may still “linger”
Once a public company is acquired for cash, markets don’t always cleanly snap to a single global “off switch” on the same second. The plumbing matters.
In the same December 11 SEC filing, Kellanova says it notified the NYSE of the consummation of the merger and requested the NYSE file a Form 25 to delist and deregister Kellanova common stock (and also referenced certain listed notes). [5]
The filing also states that after Form 25 becomes effective, Kellanova intends to file a Form 15 to suspend reporting obligations under the Securities Exchange Act. [6]
So if you’re seeing “Kellanova (K)” pages on finance portals on December 16, that’s not proof the stock is actively tradable. In many cases it’s simply the last displayed reference price and legacy data feeds continuing to show historical information while delisting and deregistration steps finalize.
Kellanova’s own Investor Relations site signals this shift, stating it is no longer being updated and includes older/outdated content. [7]
How the Mars–Kellanova deal reached the finish line in December 2025
This wasn’t a sudden surprise move; it was a long runway that finally hit touchdown.
Mars’ acquisition of Kellanova was originally announced in August 2024 at $83.50 per share in cash, with total consideration described as $35.9 billion (including assumed net leverage) in Kellanova’s deal announcement materials. [8]
From there, approvals and antitrust review became the pacing item — especially in Europe. On December 8, 2025, Reuters reported that the European Commission cleared the deal, calling it the final regulatory hurdle and noting Mars expected to close on December 11. [9]
Kellanova’s own December 8 filing similarly stated that after the EU clearance, Mars had received all required regulatory approvals and the parties intended to close on December 11, and it explicitly warned that after the merger the stock would be delisted and cease being publicly traded. [10]
By December 11, Mars publicly confirmed the acquisition was completed. [11]
What shareholders should expect now: cash payments, taxes, and “what do I do next?”
If you owned Kellanova stock through a brokerage account, the experience is typically straightforward: the position disappears and is replaced by cash once processing is complete. The exact timing depends on brokerage operations and the chain of custody.
A few practical realities worth knowing:
- Your shares are no longer “shares” in an ongoing public company. They are a right to receive the merger consideration (cash), per the merger mechanics disclosed in the SEC filing. [12]
- Appraisal rights: the filing explicitly excludes shareholders who properly exercised and perfected appraisal rights under Delaware law from the standard cash conversion. [13]
- Taxes: in general, cash-out mergers are commonly treated as taxable events for many shareholders, and Kellanova’s investor materials reference tax implications for U.S. federal income tax purposes (shareholders should rely on their own tax advisors for their specific situation). [14]
This is the moment when investing stops being about “forecast vs. fundamentals” and becomes about settlement, documentation, and tax lots.
The last big “forecast” for K stock: why Wall Street targets converged on $83.50
When a cash acquisition is signed and the market believes it will close, the stock price usually “pins” close to the deal price — not because the company stopped having fundamentals, but because the expected outcome becomes mechanical.
That’s exactly what the mainstream forecast pages were showing heading into the close:
- MarketBeat listed Kellanova’s consensus rating as Hold and a consensus price target of $83.50, implying essentially no upside beyond the deal price (a classic merger-arbitrage profile). [15]
- StockAnalysis similarly showed a price target around $83.50 and highlighted that targets were last updated earlier in 2025, reflecting how analyst coverage often goes dormant once the “story” becomes “will it close?” [16]
Even market dashboards like Finviz displayed a target price of $83.50 and the same general “Hold/Neutral” posture typical for a cash deal that has largely de-risked. [17]
Translation: by December 2025, “forecasting Kellanova stock” mostly meant forecasting deal closure risk, not forecasting earnings surprises.
Now that the deal has closed, those targets are functionally historical footnotes.
Dividend footnote: the $0.58 payout that landed right as the merger wrapped up
One more detail that mattered to many shareholders tracking total return: in October 2025, Kellanova announced a regular dividend of $0.58 per share, payable December 15, 2025 to shareholders of record at the close of business on December 1, 2025 (with the ex-dividend date also listed as December 1). [18]
With a major corporate action occurring in the same month, dividends can create confusion (“Do I get it?” “Is it included?” “Does it change the deal price?”). The cleanest approach for shareholders is to check their broker statements and the official corporate action notices tied to their account and holding dates.
“Aftershocks” on Dec. 16: Kellanova’s former CEO resurfaces at Kraft Heinz
While Kellanova is now private under Mars, the leadership and competitive landscape around it is still moving in public view.
On December 16, 2025, Kraft Heinz announced it has named Steve Cahillane as CEO effective January 1, 2026, and specifically noted that he most recently served as CEO of Kellanova until its acquisition by Mars in December 2025. [19]
Reuters also covered the same move today, tying Cahillane’s appointment to Kraft Heinz’s broader restructuring plans and noting his Kellanova background. [20]
Why this matters for people still searching “Kellanova stock” on December 16:
- It’s a reminder that Kellanova’s transformation and deal didn’t happen in a vacuum — it’s part of a larger CPG reshuffling.
- It also spotlights an awkward truth: public investors can’t buy Mars, so many will look for “the next best public proxy” for consumer packaged foods and snacking exposure — and leadership talent flows into those public proxies.
Index ripple: Kellanova exits the S&P 500, and index funds rebalance
Kellanova’s acquisition also created an index-level consequence: a removal from the S&P 500 and a replacement.
Barron’s reported that Ares Management would replace Kellanova in the S&P 500, explicitly linking the change to Kellanova’s pending acquisition by Mars and the expected close timing. [21]
For passive investors, this mattered because index funds and ETFs tracking the S&P 500 had to sell Kellanova (or process the corporate action) and buy the replacement, creating short-term flows that can show up as volume spikes around the effective date.
What’s next if you still want “Kellanova-like” exposure — now that K is gone?
With Kellanova now inside Mars, the question becomes: where does the public market price the global snacking theme now?
A few realities shape the post-Kellanova landscape:
- Mars just became even more dominant in snacks
Regulators scrutinized the combination because of concerns about pricing power and retailer negotiations. The EU ultimately cleared the deal, and Reuters summarized the Commission’s view that the merger wouldn’t raise competition concerns in the European Economic Area under its analysis. [22] - Public-market snack exposure shifts to peers
Investors looking for listed alternatives generally end up comparing large branded-food companies with global distribution and strong pricing power (or at least strong brand portfolios). This isn’t a recommendation — it’s simply where the “category exposure” conversation usually goes once a pure-play gets taken private. - Expect more consolidation logic, not less
The strategic rationale behind the Mars–Kellanova tie-up — scale, distribution, portfolio breadth, and cross-category leverage — is the same logic that keeps powering consolidation across packaged foods.
Bottom line for Dec. 16, 2025: Kellanova stock is now a corporate-action story, not a trading story
On December 16, 2025, the most accurate way to frame Kellanova stock is:
- The deal is done: Kellanova shares converted to $83.50 cash rights. [23]
- Public trading ended: trading was halted prior to the open on Dec. 11, and delisting steps are in motion. [24]
- Analyst “forecasts” had already collapsed into the deal price, reflecting limited upside once closure became likely. [25]
- Fresh news today centers on where Kellanova’s leadership talent goes next — namely, Steve Cahillane’s move to the CEO seat at Kraft Heinz starting January 1, 2026. [26]
Kellanova’s ticker may still show up in watchlists and search results for a while (financial internet inertia is undefeated), but economically, the story has moved on: Mars owns the snack engine now — and public investors have to choose different vehicles if they want to stay in that lane.
