Koch's holding company sells 700,000 Ibotta shares

The move

KDT Ibotta Holdings, the Koch, Inc. entity that holds Charles Koch's stake in Ibotta, sold 700,000 Class A shares for about $41.8 million in three open-market trades on Nov. 3 and 4, according to a Form 4 filed with the SEC. The sales cut its stake to 3,689,129 shares, down from the 4,389,129 shares it had reported owning.

Why it matters

The sales follow Ibotta's Nov. 2 earnings report, when the company beat its own revenue guidance and its stock jumped. Trimming into strength after a run-up is common and doesn't necessarily signal Koch has soured on the stock.

The bear case

Koch, Inc. still owns nearly 3.7 million shares, so this looks like partial profit-taking rather than an exit.

What to watch

Koch, Inc.'s next 13F-HR, due around mid-November, for the stake's new size.

Marvell's $115 billion Lumentum deal spooks investors

The move

Marvell Technology agreed on Nov. 2 to buy optical-component maker Lumentum Holdings in an all-stock deal with an implied enterprise value of $115 billion, the companies said in a joint press release. Lumentum holders will get a fixed 4.5 Marvell shares each, a 23.9% premium to the Oct. 28 unaffected price; Marvell holders will own about 67% of the combined company and Lumentum holders about 33%, with closing expected in the first half of 2028. Koch, Inc., the holding company run by Charles Koch, has reported owning Marvell shares in its 13F filings.

Why it matters

Marvell's release cites a $550 billion addressable market and more than $1 billion in annual cost synergies, but Bank of America cut Marvell to Neutral from Buy and its price target to $225 from $400, citing possible selling pressure from the roughly 50% increase in Marvell's share count, financial news site goldesel.de reported.

The bear case

Marvell says the deal should add to its non-GAAP earnings per share in the first year after closing, but the transaction still needs shareholder and regulatory approval, and BofA flagged that a long review could extend the stock overhang.

What to watch

Shareholder and regulatory approval for the deal, expected to close in the first half of 2028.

Ibotta tops guidance again as Koch holds a stake

The move

Ibotta reported third-quarter revenue of $97.8 million, up 17% year over year and above the top of its $94-$98 million guidance range, with adjusted EBITDA of $23.8 million, a 24.3% margin, the company said in its Nov. 2 earnings release. Koch, Inc., the holding company run by Charles Koch, has reported owning 4,389,129 Ibotta Class A shares worth about $149.9 million as of its most recent 13F filing.

Why it matters

The beat shows one of Koch's public-market stock bets still performing well, even though a move this size in a small-cap barely registers for Koch's overall portfolio.

The bear case

Ibotta's own fourth-quarter guidance of $94-$98 million revenue is only modestly above Q3's actual result, suggesting growth may be leveling off.

What to watch

Koch, Inc.'s next 13F-HR, due around mid-November, for whether it kept or trimmed the Ibotta stake.

Marvell agrees to buy Lumentum for $115 billion in AI optics deal

The move

Marvell agreed on Nov. 2 to acquire optical-components maker Lumentum in an all-stock deal valued at $115 billion, stepping up its challenge to larger rival Broadcom. Lumentum shareholders will receive 4.5 Marvell shares for each share they hold, giving them about 33% of the combined company and Marvell shareholders about 67%. Marvell says the deal expands its addressable market to $550 billion and expects more than $1 billion in annual cost synergies; CEO Matt Murphy stays chairman and CEO. The deal is expected to close in the first half of 2028. On the announcement, Marvell shares dropped almost 13% and Lumentum fell 18%. Koch, Inc., where Charles Koch is co-owner, held about 1 million Marvell shares, worth roughly $298 million, as of its most recent 13F filing.

Why it matters

This is Marvell's largest acquisition ever, a bet that bundling its chips with Lumentum's optical components will make it a bigger single supplier of the networking gear AI data centers need.

The bear case

Investors pushed both stocks down on the announcement, a sign the market is worried about integration risk and dilution on top of an already-jittery chip sector.

What to watch

Marvell's Q3 earnings commentary on the deal and the shareholder votes needed before it can close.

Marvell falls 10% in chip selloff, hitting a Koch stake

The move

Marvell Technology shares fell 10% on Oct. 30, part of the broad chip-stock selloff that followed Amazon's and Intel's earnings the day before. Koch, Inc., the industrial conglomerate run by Charles Koch, held 1 million Marvell shares worth about $297.9 million as of its June 30, 2026 disclosure to the SEC -- a stake exposed to the swing.

Why it matters

It's a reminder that Koch's public portfolio, usually associated with industrials and energy, also carries real exposure to the AI-chip trade.

The bear case

The Oct. 30 drop reflects sector-wide sentiment, not anything specific to Marvell or Koch's holding, and 13F filings lag by weeks, so the current position size isn't confirmed.

What to watch

Koch, Inc.'s next 13F-HR filing, due around mid-November 2026.

Marvell falls 8% in broad AI chip selloff

The move

Marvell shares fell about 8% on Oct. 22 to $224.64 in morning trading, part of a semiconductor-wide selloff triggered by chipmaking-equipment supplier Lam Research, which warned on Oct. 21 that supply constraints were limiting its own revenue guidance.

Why it matters

The selloff hit a stock Charles Koch's family holds as an investment, underscoring how sensitive AI-chip investors remain to supply-chain warnings.

The bear case

Marvell had already rallied sharply this year; some of the drop looks like profit-taking after a steep run-up rather than a change in its own business.

What to watch

Whether other chip-equipment makers confirm or ease Lam Research's supply warning in their own results.

Marvell slides as a chip-equipment maker flags supply strain

The move

Marvell Technology shares fell about 8% on Thursday after chipmaking-equipment supplier Lam Research said on its Oct. 21 earnings call that near-term supply-chain constraints would otherwise have lifted its revenue guidance. AMD and Intel also fell that day, down about 8% and 7%, and the iShares Semiconductor ETF dropped 6%.

Why it matters

Lam's comments raised worries that supply limits, not demand, could cap how fast AI-chip makers like Marvell can grow, after a stretch of steep valuations across the sector.

The bear case

Lam's own executives said the constraints should ease, with CEO Tim Archer predicting the industry will be "caught up very shortly."

What to watch

Marvell's next earnings report for signs the supply strain is easing.
