Physicists using SLAC's X-ray free-electron laser discovered two new laser phenomena that allowed them to generate the shortest, highest-energy X-ray pulses ever recorded (60-100 attoseconds). These breakthroughs could let scientists observe electron motion and chemical bond formation in real time. Physicists Uwe Bergmann and Thomas Linker write in an article for The Conversation: In this new study we used X-rays, which have 100 million times shorter wavelengths than microwaves and 100 million times more energy. This meant the resulting new X-ray laser pulses were split into different X-ray wavelengths corresponding to Rabi frequencies in the extreme ultraviolet region. Ultraviolet light has a frequency 100 million times higher than radio waves. This Rabi cycling effect allowed us to generate the shortest high-energy X-ray pulses to date, clocking in at 60-100 attoseconds. While the pulses that X-ray free-electron lasers currently generate allow researchers to observe atomic bonds forming, rearranging and breaking, they are not fast enough to look inside the electron cloud that generates such bonds. Using these new attosecond X-ray laser pulses could allow scientists to study the fastest processes in materials at the atomic-length scale and to discern different elements. In the future, we also hope to use much shorter X-ray free-electron laser pulses to better generate these attosecond X-ray pulses. We are even hoping to generate pulses below 60 attoseconds by using heavier materials with shorter lifespans, such as tungsten or hafnium. These new X-ray pulses are fast enough to eventually enable scientists to answer questions such as how exactly an electron cloud moves around and what a chemical bond actually is. The findings have been published in the journal Nature.

From time to time, I participate in certain stock exchange offers which include a special provision for smaller investors, called “odd lot tenders”. You can find more background information on these short-term “arbitrage” plays in the last two offers that I joined: Cummins/Atmus Filtration and Johnson & Johnson/Kenvue.

Recently, Lennar (primarily a homebuilder) announced such an exchange offer as they try to complete their spinoff of Millrose Properties (an REIT, primarily a land bank). This time, Rich Howe of StockSpinoffInvesting.com – who has a lot more experience with these deals than me – has generously agreed to share his summary and analysis of the deal. Please enjoy the following guest post:

Buy Lennar – Exchange Offer – Special Situation

October 15, 2025
LEN: $122.21
Market Cap: $30BN
Recommendation: Buy 99 shares of LEN, Exchange for shares of MRP
Expected Profit: $772 / 6.4%

Summary

Lennar (LEN) announced an exchange offer on October 10, 2025 whereby investors can exchange their LEN shares for shares of Millrose Properties (MRP), Lennar’s land bank spin-off. To incentivize the exchange, LEN investors will receive $106.43 of value in MRP shares for every $100 of value in LEN shares. I expect the exchange offer to be oversubscribed. However, there is an odd lot provision such that any LEN shareholders with 99 shares or less (odd lot provision) will not be prorated. Thus, there is an opportunity to buy 99 shares of LEN and exchange them for shares of MRP. This should result in a profit of ~6.4% / ~$757 (at current prices) in less than a month. The profit is not guaranteed (of course!) but is low risk, in my opinion. To participate in this exchange offer, you must contact your broker (you may be able to participate in the exchange offer online). It will not happen automatically.

Deadline: The exchange offer will expire on November 7, 2025. So this is time sensitive. Brokers typically require investors to give them notice about the exchange well before the official deadline. Schwab’s deadline will likely be November 5, 2025, but it would be prudent to buy on November 3, 2025 at the latest as it takes two days for shares to settle. I’m planning to buy 99 shares of LEN shares on or before November 3rd and then immediately call Schwab and ask to participate in the exchange offer. Other brokers (Fidelity, Interactive Brokers, etc.) have their own internal deadlines which are typically after the Schwab deadline.

Additional Details

Lennar (LEN) spun-off ~80% of Millrose Properties (MRP), its land bank, in February 2025.

It retained ~20% of the business.

On October 10, 2025, Lennar formally announced that it would spin off its remaining ~20% stake in Millrose Properties via an exchange offer.

I’ve highlighted key terms but you can visit the transaction’s live website with additional details.

For every $100 shares of LEN that you own, you will receive $106.38 of MRP shares.

Since this exchange represents an attractive return in a short period of time, I expect the offering to be oversubscribed (similar to previous exchange offers that I’ve covered).

However, there is an odd lot provision such that if you own fewer than 100 shares, you will not prorated.

Here is the exchange offer filing and a website which tracks the exchange offer indicative exchange ratio.

This offering is very similar to the many other split off/exchange offers that we’ve participated in.

Examples:

• CMI/ATMU Exchange – Unhedged trade worked well.
• JNJ/KVUE Exchange – Unhedged trade worked well (Iag shouldn’t have held onto KVUE shares).
• LLY/ELAN Exchange – Unhedged trade worked well.
• DHR/NVST Exchange – Unhedged trade worked well.
• ECL/CHX Exchange – Unhedged trade worked well.
• DD/IFF Exchange – Unhedged trade worked well.
• MMM/NEOG Exchange – Unhedged trade did not work.

How to Execute the Trade

LEN is currently trading at $122.21 per share.
MRP is currently trading at $31.96.
Here’s how the math works at current price levels.

Step 1
Buy 99 shares of LEN for $122.21 per share. Total cost of $12,099.

Step 2
Per the exchange offer, shareholders who elect to exchange their LEN shares will receive MRP shares at a 6% discount or at a price of $30.04 ($31.96 x (1-6%)). The MRP price hasn’t been finalized yet. But I’m using the current price plus the discount as I think that’s the best way to approximate what the actual price will be. The actual price will be determined by a formula laid out here.

$12,099 / $30.04 = 402.72 shares of MRP

402.72 shares of LEN / 99 shares of MRP = 4.07. 4.07 is lower than the max exchange ratio of 4.1367. If the ratio were higher than 4.1367, the number of MRP shares would be maxed out at 409 (4.1367 * 99).

Step 3
Sell MRP shares that are received once the exchange goes through. It usually takes Schwab about a week to process the exchange offer. I expect to receive my MRP shares by November 14, 2025 or shortly thereafter.

At current prices, the trade is expected to generate a profit of $772.

In terms of timing, the exchange offer expires on November 7, 2025 (unless LEN changes it), and so I recommend that you buy LEN shares no later than November 3rd to ensure you make the deadline (it takes two trading days for your purchase to settle and brokers internal deadlines are usually 2 days prior to the official company deadline). After you purchase shares, call your broker and ask them to tender your shares. This is important. Your participation in the exchange isn’t automatic.

I created a spreadsheet to track the profitability of this trade. Here is a screenshot of it:

Thoughts on Millrose Properties?

Millrose was created when Lennar contributed ~$5.5 billion in undeveloped, partially developed, and some fully developed land assets, along with up to $1 billion in cash, to Millrose. Millrose operates as an independent entity, acquiring and developing land to deliver finished homesites under land option contracts. At the time of the spin-off, it only served Lennar but it plans to engage with other homebuilders as well.
Lennar pays Millrose option fees for the right to buy land on Millrose’s balance sheet.

This strategic move is part of Lennar’s ongoing shift toward an asset-light operating model, aiming to reduce financial risk and enhance returns by minimizing direct land ownership.

I’m happy to own Millrose Properties at a 6% discount, but don’t want to own the stock for the long term as I believe its ability to grow and generate upside is limited given Lennar’s right to purchase its land.

What are the risks?

LEN Sells Off
If you buy LEN, and it sells off prior to the exchange, you could lose money. I’m not particularly worried about this risk, as investors will likely continue to bid LEN shares up to take advantage of the share exchange.

A major sell off could happen if some random negative news hits LEN (for instance negative news in a lawsuit). This is unlikely but did happen during the MMM/NEOG exchange offer. JNJ also had a negative court ruling during its exchange offer, but the exchange was still profitable.

If LEN does sell off, it would have to sell off by ~6.4% for you to lose money. To minimize risk, you could also short out the MRP exposure.

I looked back at the performance of the parent during similar transactions and found that it usually performs well (average: +2.2%; median: +3.8%)

The Exchange Is Canceled or the Odd Lot Provision is Removed
Lennar wants to distribute its ~20% stake in Millrose Properties and this is an efficient way to do so. I don’t expect it to be canceled, but it’s possible.
The odd lot provision could be removed, however, this has never happened for split off transactions (that I’m aware of). Nonetheless, it could happen!

Millrose Properties (MRP) Stock is Weak After the Share Exchange Closes
If the share exchange closes and investors who’ve exchanged their LEN shares for MRP shares make 6.4%, but then MRP shares immediately depreciate by more than 6.4%, this trade will lose money. In other words, this trade can lose money even though the initial math looks favorable.

While this risk is valid, I’m comfortable participating in this trade and believe it represents an attractive risk/reward.

fahrbot-bot shares a report from Popular Mechanics: [I]n a new study published in the journal Nature Materials, scientists from the Korea Research Institute of Standards and Science (KRISS) have now found yet another phase, appropriately named Ice XXI. At the heart of the experiment, scientists used diamond anvil cells (DACs) -- a common device used in materials science for squeezing samples under immense pressure -- to subject water to 2 gigapascals (20,000 times higher than normal atmosphere) of pressure in just 10 milliseconds. The scientists call this kind of water "supercompressed," and it's metastable, meaning it persists for a time even when another form of ice would be more stable. And because of the immense pressure, ice forms at room temperature but the molecules are much more densely packed. "Rapid compression of water allows it to remain liquid up to higher pressures, where it should have already crystallized to ice VI," Geun Woo Lee, a co-author of the study from RISS, said in a press statement. "The structure in which liquid H2O crystallizes depends on the degree of supercompression of the liquid."

An anonymous reader quotes a report from The Guardian: I realize that, at this point, there are already far too many shows. Every channel, every streaming service is teeming with content demanding your attention, and there are simply too few hours in the day to watch them all. However, with that in mind, may I recommend a new show called Space Live? There's only one episode. The only potential downside is that the episode literally lasts for ever. Actually, that's inaccurate. Space Live isn't a show, it's a channel. It launched on Wednesday morning, tucked away on ITVX, and consists only of live footage of Earth broadcast from the International Space Station. It's beguiling to watch, especially for anyone who didn't realize that a person can be awestruck and bored simultaneously. It's billed as a world first. ITV has partnered with British space media company Sen to use live 4K footage from its proprietary SpaceTV-1 video camera system, mounted on the International Space Station, giving us three camera views: one of the station's docking ports, a horizon view able to show sunrises and storms, and a camera pointing straight down as the ISS passes across the planet. A tracker in the corner of the screen shows the live location of the ISS, while a real-time AI information feed provides facts about our geography and weather systems. Of course, if you wanted to be picky, you could argue it isn't exactly new. Nasa's YouTube channel has been streaming live footage from the ISS for years, and uniformly draws an audience of a few thousand. But Space Live is, if nothing else, slightly snazzier. The footage is certainly nicer: at 8.30am on Wednesday, Space Live showed gorgeous images of the sun's glare bouncing off the sea around the Bay of Biscay, while all Nasa could offer was a piece of cloth with the word "Flap" written on it. There's even a soundtrack, a constant, soothing kind of hold music that loops and loops without ever becoming fully annoying. It's an improvement, in other words. And, at least for the first orbit, it is absolutely spellbinding.

Spotify has officially partnered with major record labels to create a "responsible AI" initiative aimed at developing generative music tools that supposedly benefit both artists and fans. While Spotify promises choice, transparency, and fair compensation, the vague announcement has many skeptics wondering if "responsible AI" is just another remix of old industry power plays set to a new algorithmic beat. The Verge reports: Spotify didn't detail any specific products in the works but said it was building a "state-of-the-art generative AI research lab and product team focused on developing technologies that reflect our principles and create breakthrough experiences for fans and artists." Most of the press release is dedicated to vagaries and laying out the principles that will guide Spotify's generative AI projects: [partnerships with record labels, distributors, and music publishers; choice in participation; fair compensation and new revenue; and artist-fan connection.]

EA employees and the Communications Workers of America union have condemned the company's proposed $55 billion private acquisition -- backed by Saudi Arabia's Public Investment Fund and Jared Kushner's Affinity Partners, "claiming they were not represented in the negotiations and any jobs lost as a result would 'be a choice, not a necessity, made to pad investors' pockets," reports Eurogamer. From the report: Following the announcement, there's been plenty of speculation around the future of EA and its multiple owned studios, split between EA Sports and EA Entertainment. Now, members of the United Videogame Workers union and the CWA have issued a formal response alongside a petition for regulators to scrutinize the deal. "EA is not a struggling company," the statement reads. "With annual revenues reaching $7.5 billion and $1 billion in profit each year, EA is one of the largest video game developers and publishers in the world." This success has been driven by company workers, the union stated. "Yet we, the very people who will be jeopardized as a result of this deal, were not represented at all when this buyout was negotiated or discussed." Citing the number of layoffs across the industry since 2022, workers fear for "the future of our studios that are arbitrarily deemed 'less profitable' but whose contributions to the video game industry define EA's reputation." "If jobs are lost or studios are closed due to this deal, that would be a choice, not a necessity, made to pad investors' pockets - not to strengthen the company," the statement reads. "Every time private equity or billionaire investors take a studio private, workers lose visibility, transparency, and power," it continues. "Decisions that shape our jobs, our art, and our futures are made behind closed doors by executives who have never written a line of code, built worlds, or supported live services. We are calling on regulators and elected officials to scrutinize this deal and ensure that any path forward protects jobs, preserves creative freedom, and keeps decision-making accountable to the workers who make EA successful." As such, workers have launched a petition in a "fight to make video games better for workers and players -- not billionaires". The statement concludes: "The value of video games is in their workers. As a unified voice, we, the members of the industry-wide video game workers' union UVW-CWA, are standing together and refusing to let corporate greed decide the future of our industry."
