Can Boost Run $BRUN borrow the $527-686M it needs for H2 2026 without selling stock? CFO Erik Guckel said on the Q2 call that $BRUN is working on new ways to finance the build: “We continue to innovate on financing structures beyond the equipment financing approach used to date and expect to provide additional color and progress on this over the next quarter.” The October 8 prospectus amendment names asset-backed securitizations (bonds backed by its GPUs and customer contracts) and rated parent-level debt as new forms of financing $BRUN expects to access. But I found no new facility, lender, or term sheet in its filings or press releases from August 14 to October 16. Founder and CEO Andrew Karos acknowledged on the Q2 call that there’s “a big gap in the market right now” in financing for customers without investment-grade credit. $BRUN’s named customers are private AI startups without investment-grade ratings, so its contracts are harder to borrow against. For comparison, $NBIS’s first secured loan on July 17, $775M at 2.50 points over SOFR (a short-term benchmark rate), was backed by GPUs running under a contract with an investment-grade customer. Thinking Machines Lab, the AI startup founded by former OpenAI CTO Mira Murati, alone accounts for $157.2M/year, 52.3% of what $BRUN’s disclosed contracts should bring in by year-end, and was still in talks to raise $5-6B as of early September. I found no announcement that it closed the round through October 16, so lenders financing its GPUs are also betting that the round closes. Karos also mentioned $NVDA’s AI Compute Partnership (AICP), a program NVIDIA launched in July to backstop GPU clouds’ clusters with its investment-grade credit, for a share of their revenue. However, NVIDIA paused some of its AICP deals over antitrust concerns, the Wall Street Journal reported on August 27. NVIDIA said the program is still in place, but The Information, a tech news site, reported on October 5 that NVIDIA is rethinking its revenue-sharing deals with GPU clouds. Still, lessors funded 79.5% of the H1 2026 build for GPUs already rented out on contracts worth ~1.4x their cost, so I believe $BRUN most likely borrows the $527-686M without selling stock. The Q3 report (mid-November) will show how much $BRUN leased in Q3. If lessors funded 70% of the H2 2026 build instead of 79.5%, $BRUN would need $199-259M of its own cash for the build, more than its $191.8M of pro forma cash. Covering the ~$7-67M gap and keeping three months of the ~$221M of 2027 payments in cash would take a $62-122M stock sale. At $8.89/share, the sale would mean 7.0-13.8M new shares, 8.4-16.4% of the 83.8M outstanding. So the stock at $8.89 depends less on demand or the book $BRUN has signed than on whether it can finance the next ~$1B of GPUs without selling shares at beaten-down prices.

Some notes on this post: 1) Not all of the $99.9M paid down lease debt. $BRUN's finance lease liabilities rose $207.7M on $268.3M of new finance leases, so the payments cut finance lease debt by only $60.6M. Most of the other $39.3M went to advance payments to secure new GPU leases ($37.5M in H1 2026, per the 10-Q's lease note), and the $39.7M of investing outflows paid for equipment and lease prepayments. So more than half of the $139.6M subtracted from operating cash flow was growth investment, while $BRUN added $337.3M of new GPU equipment in H1 2026. 2) The Cohere contract is also set up to be financed against. Cohere "acknowledges that Boost Run finances the equipment, facilities and working capital required to deliver the Services in part against this Agreement." $BRUN can assign its right to receive Cohere's fees to a financing party, and Cohere's obligation to pay undisputed fees is "absolute and unconditional." So $BRUN can borrow against Cohere's payments to pay for the racks, rather than funding them only from its own cash. 3) The material weaknesses behind the controls amendment weren't new. The amended Q1 10-Q says all three were "previously disclosed," including in $BRUN's S-4 (the merger filing). So the amendment corrected the original Q1 10-Q's "effective" conclusion to match weaknesses $BRUN had disclosed before the merger. 4) The CFO award's size dates to the merger, before the controls amendment. CFO Erik Guckel's May 8, 2026 employment agreement, signed when the merger closed, made him eligible for a one-time award covering 2,890,761 shares (time-based RSUs, performance-based RSUs, and options). The compensation committee's September 29, 2026 grant is 2,890,000 time-based RSUs.
I’ve been looking into $BRUN because, at these prices, it looked like it could be an attractive AI infrastructure investment. But some of what I found in the filings genuinely shocked me. I started with the cash flow. $BRUN reported $114.2 million of operating cash flow in the first half of 2026. That sounds impressive, until you see that it included a $112.9 million increase in customer deposits. Customer prepayments are useful financing, but they are not the same as recurring cash earnings. Much of that money comes with services still to deliver. Then I followed the money further down the cash-flow statement. BRUN also paid $99.9 million against finance-lease liabilities, outside operating cash flow, alongside $39.7 million of investing outflows. Subtract those from operating cash flow and you get approximately negative $25.4 million. That is my calculation, includes growth investment, and is not a steady-state burn estimate. But it is a very different picture from looking at the operating cash-flow headline alone. At that point, my question changed. I wasn’t asking how quickly $BRUN could announce more contracts. I was asking how much cash would actually remain after paying for the infrastructure behind them. So I looked at the contracts. In the appendix of its Q2 presentation, $BRUN explicitly says its total contract value includes renewal options and letter-of-intent volume that is not yet a performance obligation. That does not establish the composition of its latest contract total. But it means I need a clear reconciliation before treating headline contract value like firm, enforceable backlog. Potential renewals and committed revenue are not interchangeable. The $525.6 million Cohere agreement added another layer. If a specified minimum of infrastructure is not accepted by July 15, 2027, Cohere can terminate and recover its prepayments. Even if that minimum is met, unaccepted capacity can still be cancelled with corresponding refunds. And $BRUN’s listed parent guarantees those unused-prepayment refunds. These are contractual protections, not evidence of a cancellation, but they show how deployment problems could become liquidity problems, rather than simply pushing revenue into another quarter. Then I reached the governance disclosures, and this was where I became considerably less comfortable. $BRUN’s original Q1 filing said its disclosure controls were effective. The amended filing changed that assessment to not effective for the same reporting period, citing material weaknesses. There was no financial-statement restatement, but reversing the assessment of the systems responsible for reliable reporting is something I take seriously. On September 29, the CFO received 2.89 million restricted stock units with a grant-date value of approximately $48.1 million. They vest over time and are not a cash bonus. The company cited his role in the listing and the fact that he held no founder shares. Even with that explanation, an award of that size, following a corrected controls assessment, does not make me more comfortable as a prospective shareholder. None of this proves the business will fail. Customer prepayments can help fund growth, and successful delivery could materially improve the investment case. But I need to see that translate into durable cash generation, not just larger headline contract numbers. I started researching $BRUN because I thought the market might be overlooking an opportunity at this price, but instead I finished questioning whether I was overlooking the risks. $BRUN is a no go for me here.

Here’s where BWX Technologies’ $BWXT stock could be by the end of 2027, 15 months from now, in my bear, base, and bull cases. I value each case on 2028 adjusted EBITDA, since the market will be pricing 2028 numbers by then. For net debt, I use today’s $1.65B minus the $750M from its medical isotope sale, or $0.9B. To stay conservative, I don’t credit the FCF $BWXT earns between now and the end of 2027. Management plans to spend the cash, including on acquisitions, but hasn’t said how much or on what, so I leave out both the cash and any EBITDA acquisitions could potentially add. Therefore, each case’s value is 2028 adjusted EBITDA times the multiple, minus the $0.9B of net debt, over 92.0M diluted shares (its convertible notes only dilute above $262.51). Bear case ($118, -19%) The bear case assumes budgets slip (the government is running on a continuing resolution through December 11), the terms of its Janus contract (the Army’s microreactor program for military bases) disappoint, and new-build orders arrive later than John MacQuarrie, president of Commercial Operations, expects. That implies only 5%/year adjusted EBITDA growth to $735M in 2028, and a multiple of 16x, slightly below $BWXT’s 16.6x at the end of 2023, for a value of $118/share. Base case ($162, +11%, most likely) The base case assumes $BWXT delivers its 2027 framework (high-single-digit growth to $720M of adjusted EBITDA) and grows 10% in 2028 to $790M as new-build revenue starts. That implies the multiple holds at 20x, near today’s, for a value of $162/share. $BWXT’s own 2030 plan goes further. Today’s $15.0B EV is 13.0x the $1.15B midpoint of its 2030 adjusted EBITDA target. If $BWXT hits that midpoint, trades at 18x instead of the base case’s 20x, and runs at 2.5x net leverage (~$2.9B of net debt) after deploying its capital, the stock would be worth $194/share at the end of 2029. With ~$4/share of total dividends through 2029, that’s a 9.9%/year return from $145.70. But getting from the base case’s $790M in 2028 to $1.15B in 2030 takes ~21%/year growth, more than double the 2028 pace, so the new orders and acquisitions outside $BWXT’s predictable core (the programs backed by backlog and long-term contracts) have to show up. Bull case ($204, +40%) The bull case assumes a new-build order lands by early 2027, $BWXT signs a Janus contract on par with microreactor startup Radiant’s (up to $750M), and margins rise toward 20%. That implies adjusted EBITDA of $820M in 2028 and a re-rating to 24x, just under the 24.8x of Curtiss-Wright $CW today, for a value of $204/share. Notably, none of the three cases considers a commercial BANR (microreactor) sale, a Wyoming TRISO fuel plant, a battleship reactor, or a data center customer, so at $145.70/share, you’re getting commercial microreactors and data centers as a free option.

Here’s what Boost Run $BRUN has already committed to pay, and what it still has to finance in H2 2026. $BRUN’s GPUs need space and power, which it rents in other companies’ data centers (colocation). The four leases signed since April already cover the space and power for the year-end deployments, and CEO Andrew Karos said its partnerships now reach 253 MW of power. $BRUN owes the rent on those sites whether or not the GPUs get financed. In 2027, the commitments $BRUN has already signed call for ~$221M of payments, including $103.5M on its GPU leases, $28.9M of rent on the sites in use as of June 30, ~$69M on the four new leases, and $20M for software. $BRUN’s $191.8M of pro forma cash and $93.6M of contracted prepayments, $285.4M together, cover the ~$221M of 2027 payments before counting any monthly billings from customers. But the same cash also pays $BRUN’s share of the H2 2026 build, so its monthly billings will have to cover part of the 2027 payments. To reach the $1.0-1.2B of GPU spending management expects for 2026, $BRUN has to deploy $663-863M of GPU servers in H2 2026, 2.3-3.0x its cash and contracted prepayments. If lessors fund 79.5% of the H2 2026 build, as they did in H1 2026, $BRUN needs $527-686M of new leases, 2.2-2.9x the $238.1M the company owed on finance leases as of June 30. The other $136-176M would be paid in cash. The $527-686M works out to $264-343M/quarter on average across Q3 and Q4, 1.3-1.6x the $208.2M of leases $BRUN took on in Q2. $BRUN’s lease debt would rise by less than the $527-686M, since the company keeps paying down its leases while adding new ones. During H1 2026, its finance lease debt rose $207.7M on $337.3M of new GPU equipment, or 61.6%, which for H2 2026 would imply ~$410-530M more debt. New leases will likely cost more than ~7% after the rise in rates. For context, at the 9.0% $IREN agreed to pay on its August GPU financing, the extra interest on $527-686M would be ~$6.5-8.5M/year, 1.6-2.1% of the $400M ARR target. And $BRUN isn’t slowing down. By June 30, the company had already placed orders well above the $578M first-year minimum in its April 2026 agreement with Dell $DELL, which also requires at least $215.5M/year of Dell equipment from April 2027 to April 2031 or a payment for the shortfall.

In September 2026, the S&P 500's CAPE ratio was 40.4, more than double its average of 18 since 1881. The only higher readings came in 20 months of 1999 and 2000 and in August 2026. After readings of 30 or above, the S&P 500 lost 1% per year on average over the next 10 years, and stocks across 25 countries returned 2.1% per year. → Full video: youtu.be/M0xOa5Zfxco

Across 25 countries, the markets with CAPE ratios below 10 lost 8.3% per year on average over the next 10 years because of one country, Russia: without it, that group returned 11% per year. Russia's CAPE ratio was below 10 every month from October 2008 to February 2021, and in March 2022, MSCI valued Russian stocks at effectively zero. → Full video: youtu.be/M0xOa5Zfxco

Curtiss-Wright $CW is BWX Technologies’ $BWXT closest comp, and $BWXT trades below it on every measure but FCF yield. Since naval propulsion is close to half of $BWXT’s revenue, its closest comps are other Navy suppliers. Small-reactor developers like Oklo $OKLO and NuScale $SMR wouldn’t work anyway, as they lost $73.2M and $64.0M from operations in Q2 2026, leaving no EBITDA multiple to compare against. So I decided to compare $BWXT with four listed companies building or equipping the same Navy submarines and carriers: → Curtiss-Wright $CW: Pumps, valves, and turbines for the same submarines and carriers, plus reactor coolant pumps for Westinghouse’s AP1000. → Leonardo DRS $DRS: Naval power and propulsion systems, including electric drive equipment for the Columbia-class. → General Dynamics $GD: Builds the submarines through its Electric Boat unit. → Huntington Ingalls $HII: Builds the carriers and submarines at its Newport News shipyard. Here’s how they compare on 2026 estimates (P/E, EV/EBITDA, EV/sales, FCF yield): → $BWXT: 30.7x, 22.5x, 3.95x, 2.64% → $CW: 36.3x, 24.8x, 5.54x, 2.90% → $DRS: 26.9x, 18.4x, 2.48x, 2.78% → $GD: 19.7x, 13.9x, 1.68x, 5.34% → $HII: n/a, 12.3x, 0.98x, 5.28% Note: CW’s, GD’s, and HII’s EBITDA is operating income plus D&A from company guidance, since they don’t guide EBITDA. $BWXT trades above the two shipbuilders, which earn thinner margins. HII guides shipbuilding operating margins of 6.0-6.5% and GD 10.5% overall, vs. $BWXT’s 12.6% GAAP operating margin in 2025. A reasonable EV/EBITDA range for $BWXT is 16-24x, between its own end-2023 multiple and Curtiss-Wright’s today.

TIPS are Treasury bonds whose principal rises with inflation. In September 2026, the 10-year TIPS yield averaged 2.6% per year above inflation, its highest monthly average since November 2008, and more than the S&P 500's earnings yield based on the CAPE ratio, 2.47%, for the first time since at least 2003. → Full video: youtu.be/M0xOa5Zfxco

Only part of the $1.0-1.2B Boost Run $BRUN expects to spend on GPUs in 2026 is paid in cash up front. $BRUN plans to pay for the GPUs with (1) customer prepayments and operating revenue and (2) equipment leases that spread the cost over the lease term and generally end with an option to buy the GPUs outright. During H1 2026, lessors (the companies that buy the GPUs and lease them to $BRUN) funded $268.3M of new GPU equipment through finance leases. $BRUN made $39.4M of advance payments to secure those leases and paid $29.6M in cash for equipment it bought outright, so lessors funded 79.5% of its $337.3M of new GPU equipment. The $268.3M came from 34 separate GPU leases with 30- to 36-month terms, and the June 30 lease schedule implies an interest rate of ~7%. Its finance leases as of June 30 call for $103.5M of payments in 2027 and $99.8M in 2028, then just $12.1M in 2029, about when its three-year contracts end. So the lease debt runs off with contracted revenue, not with renewals $BRUN still has to win. Customer deposits, the payments customers make up front on their contracts, were $128.4M as of June 30. New deposits made up $112.9M of H1 2026’s $114.2M of operating cash flow, while $BRUN paid $99.9M on its finance leases over the same six months. Effectively, customers’ prepayments are already paying for the GPUs they rent. Founder and CEO Andrew Karos said on the Q2 call that every deal $BRUN closes comes with a prepayment, averaging 22% of total contract value (TCV). The June and July orders alone carry $93.6M due by their start dates ($37.9M on November 30 and $55.6M in installments through March 2027). Karos also said $BRUN’s TCV-to-capex ratio, its contract value divided by what the GPUs cost, keeps rising to 1.4 and above as contracts get longer. So a three-year contract brings in ~$1.40 for every $1.00 of GPUs, which also has to cover the lease interest, the rent, and the staff. In other words, a three-year contract mostly covers the GPUs and the cost of running them, so how much $BRUN makes on those GPUs depends on renting them out again after the leases end in 2029, without lease payments, at whatever older B300s fetch by then.

A CAPE ratio above 40 doesn't necessarily mean stocks are about to crash. Over the 10 years after September 2016, the CAPE ratio was above 30 in 80 of the 120 months, and the S&P 500 still returned 11.6% per year after inflation. In June 1997, it rose above 30 for the first time since 1929, and the S&P 500 rose another 70% before it peaked in 2000. → Full video: youtu.be/M0xOa5Zfxco

$ATII now base:0x1a5f7931e5d450c666fd8706300b984fc4aeaba3 -- Forge Nano completed its de-SPAC merger and will list on NASDAQ on October 22, 2026. The merged company will receive $100M from the PIPE investor, who buys 2.97M shares, 7.03M pre-funded warrants (effectively shares), and 15M warrants at $10. An additional warrant reset could add more dilution if the stock is below $10 after six months, with a floor of $7.28 if a $200M debt deal is secured. Over 22 million SPAC shares were redeemed for $238.4M (approx. $10.73/share), leaving only $8.4M in the trust account for the combined company! Not the greatest as this significantly limits the cash available for operations and growth. On the other hand, the company has expanded its Taiwan semiconductor footprint, demonstrated a 1,000:1 coating demo, deeper Samsung SDI ties, a pharma JV with Nanexa, and broke ground on its North Carolina battery gigafactory.
