DK Street Journal

On 31 July, the Financial Times reported that NXP Semiconductors was in talks to acquire Ambarella in a deal worth more than $3bn. Ambarella shares rose 16.1% that day on 9.2m shares, against typical volume of one to two million. Strip out that one session and the stock's entire last month amounts to about 2.6%.

Ambarella designs low-power system-on-chip silicon that squeezes video compression, image processing and computer vision onto a single part, sold to the makers of dashcams, security cameras, driver-assistance modules and robots. It is, on the user's own reading of the field, effectively the only Western listed pure-play left: Mobileye is roughly 88% owned by Intel, Hailo is private, and the Chinese alternatives are largely closed to Western original-equipment makers on export-control grounds. That scarcity is the takeover logic. Automotive is expected to supply about half of NXP's projected $15.1bn of 2026 revenue, and the deal would arrive in a consolidating industry that has already seen Texas Instruments buy Silicon Labs for $7.5bn this year.

The business behind the bid

What the report did not change is the trajectory. Ambarella's year-on-year revenue growth has decelerated for four consecutive quarters — 49.9%, then 31.2%, then 20.1%, then 16.9% in the quarter ended 30 April, on revenue of $100.4m. Gross margin has held up through it, at 59.1% in that quarter against 57.6% a year before, and the GAAP operating margin improved to -18.1% from -30.1%. The company is still loss-making. Consensus has full-year revenue growth of 13.2%, to $441m.

The shares carry 15.2x trailing gross profit, up from roughly 13.1x six months ago, and 104x forward earnings. Analysts pointed out that near $90 the company was worth about $4.0bn, or 9.6x trailing revenue — more than twice NXP's own sales multiple, and that a customary 25% premium to the pre-report close of $74.09 works out to $92.61, barely above where the stock traded on the news. Talks could still collapse. Ambarella has not reported since 28 May; it guided the current quarter to $105m-$111m.

The licensor that beat and fell

CEVA sells no chips. It licenses digital signal processor cores, its NeuPro neural-network accelerators and wireless connectivity designs to chipmakers, taking an upfront fee and then a royalty on every unit its customers ship. Four hundred employees produce an 87.4% gross margin — which is why the near-identical price-to-sales ratios of the two companies, 8.0x and 8.9x, mislead, and why gross profit is the fairer yardstick.

CEVA's growth has accelerated for four straight quarters, from 4.3% to 13.1%, and on 10 August it reported quarterly revenue of $29.0m with licensing up 21% to $18.2m — its strongest licensing quarter in three years. Non-GAAP operating margin reached 11%, from 3%. Management raised full-year growth guidance to 13-15% from 12%. The shares fell about 10% anyway, and are down 31.3% from their 15 June high.

There is one genuine problem in those numbers. Customers shipped 567m royalty-bearing units, up 16%, yet royalty dollars grew 1%, to $10.8m. Bluetooth volumes fell 16%, to 295m units, and low-priced consumer connectivity carried the mix — so the average royalty per unit is eroding even as units climb. Management's answer is to sell whole subsystems rather than components: ten licensing agreements last quarter, including one with what it described as a leading global AI and computing platform company that picked its NeuPro-M accelerator for custom silicon, with 18 to 24 months to production.

On price-to-gross-profit, CEVA has cheapened to 9.2x trailing from roughly 10.8x three months ago, as trailing gross profit rose 3.3% and the stock fell 12.4%. Ambarella trades at a 66% premium on the same measure. CEVA holds $221m of cash against a $927m market value.

The third name

Much of CEVA's drop was not about CEVA. In the last week of July, chip stocks lost more than $1 trillion of market value on reports that SK Hynix was slowing memory capacity expansion; CEVA fell 20.9% in that window and Ambarella, cushioned by its own story, was flat.

indie Semiconductor, which designs automotive chips for driver assistance, in-cabin systems and connectivity, is the third edge name often grouped with them. It grew revenue 24% to $64.0m last quarter, guided the current one to roughly 30% growth, and reported gross margin down to 36.1% from 40.6% with a $37.1m net loss. Its 18.8% jump on 14 August came with no discoverable company-specific news that day — CEVA rose 8.6% alongside it while Ambarella was unchanged and Broadcom fell 6.8%. It looks like a squeeze in small edge-AI names, and indie's own vision chip competes with Ambarella rather than validating either.

The setup

Where it stands — Ambarella's month is a takeover report; CEVA's is a sector selloff layered on royalty-mix erosion. Would confirm — CEVA's royalty dollars growing in line with unit shipments in the September quarter. Would invalidate — Ambarella reporting revenue above its $105m-$111m guide with growth reaccelerating past 20%. Watch next — Ambarella's fiscal second-quarter results, due late August; CEVA guided the September quarter to $30.5m-$34.5m. Valuation — Ambarella 15.2x trailing and 14.0x forward gross profit, versus CEVA's 9.2x and 8.6x.

The detour that pays

The Strait of Hormuz, the channel through which about a fifth of the world's oil normally passes, has been closed to shipping aligned with the United States and Israel since early March. The International Energy Agency has called it the largest disruption in the history of the global oil market. A renewed naval blockade took effect on 14 July. Cargoes that once crossed the Gulf now go around the Cape of Good Hope, a detour of roughly 3,800 nautical miles that ties up each ship for an extra 10 to 14 days.

Tanker owners are paid a rate per day, not a price per barrel. Take ships out of circulation and the daily rate goes vertical. Very large crude carriers loading in the Middle East for Asia fixed at close to $500,000 a day in July, against a normal range of $20,000 to $60,000. Lloyd's List described the year as the second-best tanker boom in history.

The accounts caught up fast

Okeanis Eco Tankers, a Piraeus-based owner of modern supertankers and Suezmaxes that runs its whole fleet on the spot market with 14 employees, reported second-quarter revenue of $318.9m, up 239% from a year earlier. Gross margin was 76.7%. Its fleet averaged $181,000 a day at 99% utilization, and it paid a record $5.25 per share dividend, its seventeenth consecutive. First-half distributions came to 90% of net income.

Teekay Tankers, a Bermuda-based operator of roughly 48 crude and product carriers, grew revenue 63% to $379.5m and lifted operating margin to 50.0% from 23.6%. It generated about $200m of free cash flow in the quarter against a cash breakeven near $9,700 a day, and holds more than $1.2bn in cash with no debt. It nonetheless held its quarterly dividend at $0.25 a share, telling investors it was intensifying capital-allocation discussions with its board.

Ardmore Shipping, which moves refined products and chemicals on mid-size vessels for oil majors and traders, grew revenue 61% to $116.2m and widened gross margin to 47.8% from 23.0%. Its medium-range tankers earned $51,900 a day against an operating breakeven of $10,800. Management put its leverage plainly: every $10,000 a day of extra rate is worth about $2 a share of annual earnings.

What the cheap multiple is struck on

Teekay trades at 5.00x trailing and 5.25x forward earnings, 1.25x book and a 12.4% trailing free-cash-flow yield. The forward multiple sitting above the trailing one is the tell: the market is pricing no further growth. Consensus agrees emphatically, modeling Teekay's earnings per share falling from $16.20 this year to $8.84 next, a 45% drop that puts the shares nearer 9.6x. The same fade is embedded everywhere — down 59% at Okeanis, 43% at Ardmore, 36% at Hafnia. On 2027 numbers the group is a 10x business, not a 5x one.

Ardmore is the one name where the asset test is clean: 1.03x book value, essentially the steel, after a 68% twelve-month gain. Okeanis is the inverse — the cheapest earnings multiple at 4.35x forward, on the second-richest asset multiple at 2.67x book and a 1.9% free-cash-flow yield, because it pays nearly everything out.

Nordic American Tankers, which owns 24 Suezmax crude carriers, is the clear outlier and the one name whose price has run past its accounts. It is up 138% over twelve months, the biggest gain of the five, and trades at 26.0x trailing earnings, 3.12x book and a negative 6.0% trailing free-cash-flow yield. On 2027 consensus of $0.30 a share, that is 22x.

Hafnia diverges the other way. The largest of the five by market value, running about 200 product tankers plus pools and technical management, it has fallen 10.5% over three months while its first-quarter operating margin widened to 22.4% from 13.8% and net income rose 184%. It trades at 5.68x forward against 8.41x trailing, the widest compression in the group, on an 11.4% free-cash-flow yield. Its second-quarter figures are not yet in the data.

The supply answer is not the same for both trades

The orderbook argument that supported crude tankers a year ago has inverted. Vessels on order have climbed to about 27% of the operational crude fleet, from an average near 15% in May 2025. Shipyards took 183 supertanker contracts in the first half of 2026 against 18 a year earlier, and roughly 83% of those deliver in 2028 and 2029. Okeanis' own management calls a 32% orderbook a genuine medium-term supply consideration. And the below-asset-value defence is weaker than it looks, because asset values are themselves peaked: a five-year-old supertanker now costs about $9m more than ordering a new one.

Product tankers, where Ardmore and Hafnia sit, are tighter. Ardmore puts the medium-range orderbook at 16% of a fleet averaging 14 years old, and the smaller Handysize book at 6% against an 18-year average age.

The month was four days

Strip the calendar and the recent advance thins out. Across the 22 sessions to 14 August, the five names' equal-weighted daily returns sum to +9.5%, of which two Hormuz headline sessions — 21 July and 13 August — supplied 7.8 points. Four sessions carry the whole month. One apparent drop is not one at all: Okeanis fell 5.7% on 14 August because that was the ex-dividend date for its $5.25 payout. And the rate premium hangs on diplomacy: Iran and Oman failed to agree on reopening the strait in mid-August after a week of optimism.

The setup

Where it stands — Record daily rates from a closed strait have produced the best quarter these owners have ever reported, on multiples struck against peak-year earnings.

Would confirm — Third-quarter realized rates landing at or above the days already booked: $105,000 for Teekay's Suezmaxes, $207,000 for Okeanis' supertankers.

Would invalidate — A negotiated reopening of Hormuz returning Gulf-to-Asia voyages to direct routing, which removes the extra 3,800 nautical miles of demand.

Watch next — Hafnia's delayed second-quarter results, the only member whose exposure to the rate spike is still unreported.

Valuation — Group at 4.35x-6.08x forward earnings on 2026 consensus, near 10x on 2027; Nordic American at 26x trailing and 3.12x book.

The Federal Communications Commission (FCC) is drafting a measure that would bar US imports of newly certified Chinese optical transceiver modules — the plug-in devices that convert a server's electrical signal into laser light. When Caixin reported the draft on 4 August, every Western maker of fiber, connectors and optical systems rose together; Innolight, the most exposed Chinese supplier, holds roughly a third of the world module market, and officials cautioned the rule could still be modified or shelved. Eight days later Lumentum, a laser and transceiver maker outside this group, printed a 109% revenue increase and the same names jumped again.

Those two sessions are the month. Take each company's two best days out of the trailing 30 and the group goes from +8.6% equal-weighted to -8.8%, with Belden the only survivor. Fabrinet, up 20% over the month, has not reported at all — its fiscal fourth quarter lands after the close on 17 August. Ciena's next numbers are due 3 September.

What they actually delivered

The results these companies filed in July were the best in years. Amphenol, which designs the connectors, busbars and cable assemblies that route power and signal inside a server rack, grew revenue 55% to $8.76bn last quarter, with gross margin up 417 basis points. Its information-technology and datacom line reached 43% of sales and grew 89%. Orders hit a record $10.7bn — a book-to-bill of 1.23x, meaning it took in nearly a quarter more work than it shipped.

One structural note the label on this group no longer captures: CommScope, long the reference name in fiber and cable, sold its Connectivity and Cable Solutions business to Amphenol for $10.5bn, closing in January. Amphenol has since raised that unit's 2026 sales guidance to $4.6bn from $4.1bn.

Ciena, which sells coherent optical transport gear and the Waveserver systems that link one data center to another, grew 39.5% to $1.57bn with gross margin up 381 basis points to 44%. Backlog rose past $7.7bn and cloud providers now account for 46% of revenue. The shares are down 26% over three months.

Corning, which draws optical fiber and also makes display and phone glass, grew its Optical Communications segment 32% to $2.07bn, with enterprise sales up 65%. It fell as much as 20% in a single session on 28 July — its worst day since 2002 — because guidance landed marginally under consensus. Meta has committed up to $6bn for fiber through 2030, and Corning has signed Amazon and NVIDIA agreements since.

TE Connectivity, a connector and sensor maker, grew 13.8% to $5.16bn with orders up 27%. Its data-networking unit grew 34% organically on orders up 70%, and management expects more than $3bn of AI cloud revenue by 2027 — while insisting copper stays the in-rack workhorse and optical content only turns material from 2028. Belden, which sells cabling and connectivity panels alongside industrial networking gear, grew 11.6% to $750m with gross margin up to 39.1% and record orders of $836m. Fabrinet, the outsourced contract manufacturer that physically assembles transceivers for others, has accelerated three quarters running, from 21.6% to 39.3%, on a gross margin of just 11.6%.

Lumen, the carrier selling wavelength and dark-fiber capacity, is the exception: revenue fell 9.3% to $2.81bn, it lost $88m at the operating line, and annual revenue has dropped every year since 2021, from $19.7bn to $12.4bn.

Cheaper than in May

Because gross margins here run from 12% at Fabrinet to 44% at Ciena, price-to-gross-profit is the only multiple that compares them. Against this desk's readings from 3 May, five of the seven now cost less per dollar of gross profit: Fabrinet 40.3x from 49.3x, Ciena 25.3x from 31.1x, Amphenol 18.4x from 21.2x, Corning 23.2x from 26.3x, Lumen 1.22x from 1.55x. Prices were net -2% equal-weighted over that span. The group re-earned its level rather than re-rated it. Belden alone widened, to 5.08x from 4.81x.

That cuts differently by name. Amphenol rose 36% over three months and still got cheaper. TE is the cheapest large member at 18.9x forward earnings and a 5.8% free-cash-flow yield. Corning's compression comes off a rich base — 50.8x forward earnings. Lumen's is the ordinary kind, cheapening because the business is shrinking.

The caveats inside the good quarters

Six of the seven trade with their 50-day average below their 200-day, and the group sits an average 23% under its 52-week high. The twelve-month doubling is two names: Ciena up 351%, Corning up 152%, against TE up 7%. Meanwhile Corning's carrier line grew 1% last quarter, Amphenol guided its communications-networks business down mid-teens sequentially, Belden carries roughly 3.9x leverage after buying RUCKUS, and Lumen's quarter included $36m pulled forward from the second half. Amazon, Alphabet, Microsoft and Meta are guiding to $635-665bn of 2026 capital spending, up about 72%; the argument is over whether workloads arrive to fill it.

The setup

Where it stands — Order books and margins accelerated across six of seven names while their multiples compressed and most shares stayed below spring highs. Would confirm — Fabrinet's 17 August fourth quarter showing datacom revenue growth at or above last quarter's 39.3%. Would invalidate — Book-to-bill falling below 1.0x at Amphenol or TE, or Ciena's 3 September backlog dropping from $7.7bn. Watch next — Ciena reports fiscal Q3 on 3 September; the FCC's transceiver rule remains a draft. Valuation — Group price-to-gross-profit fell at five of seven since May; Corning still carries 50.8x forward earnings, TE 18.9x.

The cost that ate the parts list

Memory chips now account for roughly a third of what it costs to build a personal computer. HP Inc., which sells laptops, desktops, workstations, displays and printers to households and corporate technology departments, told investors in February that memory had reached about 35% of a PC's bill of materials — double the 15-18% of the quarter before — and that the share would keep climbing through the year. The research firm TrendForce expects contract prices for PC dynamic random-access memory (DRAM) to rise 15-20% in the third quarter alone, with server memory still climbing through the second half of 2027.

Manufacturers have responded by shipping fewer machines at higher prices. IDC counted 68.2m PCs shipped worldwide in the second quarter, down 4.9% year on year, the first contraction after nine consecutive quarters of growth. It then cut its 2026 shipment forecast to -11.3%, from -2.4% projected last November, and pushed any real recovery out to 2028. Even so, IDC expects the market's total value to rise to about $274bn. That is inflation, not a refresh cycle.

HP: the top line is real, the operating line is not

HP's most recent quarter, ended in April, was its best in two years on revenue: $14.41bn, up 9.0%, accelerating from 6.9%, 4.2% and 3.1% in the three quarters before it. Gross margin widened to 20.93% from 19.64% in the prior quarter. Below that, the picture reverses — operating income fell 6.4% year on year, after a 10.2% drop the quarter before, and operating margin slipped to 4.25% from 4.95%. Analysts model fiscal 2027 revenue of $57.79bn, up 0.2%, and earnings per share of $3.02, unchanged from this year.

That flat earnings stream is what has re-rated. On the same consensus figure, HP traded near 6.4x forward earnings at $19.26 in mid-February and about 10.0x at $30.11 last week — roughly 56% of multiple expansion with no change to the two-year earnings path. It is not an expensive stock in absolute terms: 10.99x trailing earnings, 8.54x trailing enterprise value to EBITDA, and a 13.7% trailing free-cash-flow yield. But nothing HP itself has published explains the month. Its last earnings call was 27 May. Its two biggest up-days were borrowed: a broad rally in AI hardware on 4 August that also lifted Dell 10% and Super Micro 9% with no company-specific catalyst, and a 13 August pop on a read-across from Lenovo's results. Strip those two sessions and the 30-day gain falls to roughly 12%. Morgan Stanley moved the other way, cutting HP to underweight with a $24 target and trimming its fiscal 2026 gross-margin estimate by 90 basis points, to 19.7%.

Corsair: one session, and the memory problem inside the print

Corsair Gaming, a $1.4bn maker of gaming keyboards, headsets, Stream Deck controllers and Elgato streaming gear as well as power supplies, cooling and memory modules for self-built PCs, is the month's outlier. Its entire 30-day gain came on 7 August, when the stock rose 35.25% on volume seven times normal after a clear beat and raise — adjusted EPS of $0.23 against $0.07 expected, and full-year guidance lifted to $0.85-0.94 from a $0.72 consensus. Excluding that day, the month is +2.6%.

The quarter itself is split down the middle by memory. Revenue actually fell 1.8%, to $314.3m. Record gross margin of 33.2% includes a one-off $15.6m tariff refund worth about 500 basis points; underlying margin is nearer 28%. Components and systems revenue dropped 9%, to $198.5m, because high DRAM prices are causing enthusiasts to defer builds — memory inflation is suppressing Corsair's volumes, not just its costs. Management guided memory gross margin down from about 23% this quarter to the high teens next. The peripherals half is the healthy one: revenue up 13%, to $115.9m, at 44.9% gross margin, led by Fanatec sim-racing gear. Cash flow is genuinely better — operating cash flow rose 148%, to $74.8m. The multiple has nearly doubled since May, from about 10x forward consensus at $7.36 to 18.0x; against the raised guidance midpoint it is closer to 14.5x, versus 41.4x trailing.

Logitech: the business the market ignored

Logitech, the Swiss maker of mice, keyboards, webcams, headsets and video-conference room systems, is the one delivering and the one going nowhere — down 3.6% over three months. Its June quarter brought $1.227bn of revenue, up 6.9%, with gross margin of 49.5% against 41.9% a year earlier and non-GAAP operating income up 44%, to $290m. Operating income on the reported basis grew 59.5% on 6.9% more revenue. The shares fell 5% the next day.

The reason is not memory — Logitech has secured its supply through fiscal 2027 and raised video-collaboration prices 13% in May to cover the cost. It is that a semiconductor supplier's plant closed in late June with no reopening date, costing about $20m of sales last quarter and up to $200m this one. Guidance reflects it: 0-3% constant-currency growth and gross margin down to roughly 44%. Management also rejects the premise that it is paid per PC shipped, noting that fewer than half of PCs have a mouse and under 30% a keyboard, and that attach rates rise about a point a year. Logitech trades at 18.77x trailing and 18.38x forward earnings — no re-rating at all, the mirror image of its two supposed segment-mates.

The common thread across all three is a cost, not a cycle, and it has shown up nearby before: CDW fell 12% on record sales as memory narrowed its margin, and Dell's gross margin dropped 337 basis points as memory prices roughly doubled. Upstream, the suppliers have stalled — over the past month Sandisk is down 2.0% and Western Digital 8.4%, while Micron is up 3.7%.

The setup

Where it stands — HP has re-rated on borrowed catalysts while PC units contract; Corsair's raise is real but memory margin is guided lower; Logitech's earnings outran its shares.

Would confirm — HP's late-August fiscal Q3 showing Personal Systems gross margin at or above 20.9% with operating income growing again.

Would invalidate — HP guiding fiscal 2027 gross margin toward Morgan Stanley's 19.7%, or IDC cutting its shipment forecast below -11.3%.

Watch next — HP's fiscal third-quarter report, due late August; Logitech's supplier reopening date; Corsair's Q4 memory margin.

Valuation — HP 10.99x trailing and 9.96x forward, against 6.4x forward in February; Corsair 41.4x trailing, 18.0x forward; Logitech 18.8x and 18.4x.

Copper producers have just closed one of the strangest reporting seasons in the industry's recent history: several of them pulled the metal out of the ground last quarter at essentially no net cost. Hudbay Minerals, which mines copper concentrate in Manitoba, Saskatchewan and Peru, reported a consolidated cash cost of minus $0.40 a pound — the gold it sells alongside the copper covered the entire bill, contributing 38% of gross revenue. Southern Copper, the biggest producer of the group, put its cost after by-product credits at $0.05/lb against a realized copper price of $6.04/lb, up 40% on the year.

Those results sit under a nine-company group of copper, aluminum and rare-earth miners that supply the wire, busbar and magnets consumed by data-center construction. J.P. Morgan estimates a single large AI facility can require up to 50,000 tonnes of copper, and BHP projects data-center demand growing from about 500,000 tonnes a year now to some three million by 2050. The group has gained about 19% over the past month. The businesses beneath it did not move in anything like that pattern.

The month was really four sessions

The gains are wildly uneven: Ero Copper +33.3%, Hudbay +21.4%, USA Rare Earth +15.5%, Teck +9.6% and Freeport-McMoRan +9.1%, against Alcoa +2.9%, Rio Tinto +2.2%, Southern Copper +1.7% and BHP +1.5%. Remove each company's two best trading days from the window and six of the nine turn negative — Southern Copper at -10.2%, Alcoa at -7.2%, BHP at -6.5%. Only Ero (+12.9%) and Hudbay (+3.9%) survive the exercise.

Those best days were shared. On 4 August every member rose at once, with Southern Copper up 4.98% and Freeport up 5.75% while a copper futures fund gained 1.26% — the equities amplified a modest commodity move. Similar synchronized gaps landed on 21 July, 30 July and 7 August. The mechanism is visible in the metal itself: September copper futures in New York hit a record $6.7140/lb on 12 August, London cash copper closed at a $207.50-a-tonne premium to the three-month contract as immediately deliverable metal grew scarce, and Washington exempted refined copper from Section 232 tariffs on 31 July before the Commerce Department recommended a phased 15% levy from January 2027. A smelter outage on ore from Freeport's Grasberg mine tightened supply further.

Step back and the advance shrinks. Over three months the nine average -5.8%. Over six months they average +2.4%. The +80% twelve-month figure was earned almost entirely before February.

What the numbers say, name by name

Southern Copper, a $154bn integrated miner and smelter controlled by Grupo Mexico, posted the group's best quarter: revenue $4.29bn, net income $1.67bn, up 71.5%. Yet its copper output fell 3.5% to 230,662 tonnes, with Peru down 12% on lower ore grades at Toquepala and Cuajone. Full-year guidance still went up 1%, to 917,000 tonnes, and management expects 2027 to look much the same. It is also the group's most expensive share: 27.0x trailing and 24.1x forward earnings, 15.8x EV/EBITDA and 12.1x book value. Flat production at a rich multiple is why the best quarter drew the smallest response.

Ero Copper, a $3.5bn Brazilian producer running the Caraiba complex in Bahia and the Tucuma mine in Para, is the one name whose share move the accounts support. Revenue grew 73.9% to $284.3m, gross margin reached 42.7%, cash costs ran at $2.42/lb, and renegotiated smelter treatment charges will save roughly $20m in the second half. Net debt fell $38m to $453m, taking leverage to 0.8 times from a 2.6 times peak. Despite a 33% month, its price against gross profit is unchanged from early May, and forward earnings (8.7x) sit below trailing (11.3x). The caveat is consensus itself: after 60% revenue growth this year, analysts model 9.5% next year and declines after that.

Hudbay, at $11.9bn, grew revenue 21.4% to $651m with gross profit up 51.2% and guided 2027 copper output 24% higher, to about 150,000 tonnes. But its forward price/earnings of 17.7x now sits above its trailing 15.8x, and its price-to-gross-profit has expanded from 7.5x in May to 12.2x. The business is improving; the shares repriced faster.

Freeport-McMoRan, the largest listed copper miner, was the only one whose revenue fell — down 7.3% to $7.03bn as Grasberg recovered from disruption. Output there doubled to 69,000 tons a day by June from 34,000 in April, and the company cut full-year unit net cash cost to about $1.90/lb while guiding second-half copper sales more than 20% above the first. Management framed the leverage plainly: every $0.10/lb on the copper price is worth about $390m of annual EBITDA. At 32.8x trailing and 22.8x forward earnings, with its multiple of gross profit up from 8.3x to 13.8x since May, much of that is already priced.

Alcoa, the $13.2bn bauxite, alumina and aluminum producer, is the group's contradiction. Record revenue of $3.97bn, up 31.4%, and a record $1.1bn of aluminum-segment EBITDA came alongside a cut to full-year alumina output — 9.5-9.6 million tonnes, from 9.7-9.9 million — after an oxalate outbreak at the Pinjarra refinery and cyclone-related gas disruption, plus an earnings miss. It also agreed to buy South32's bauxite and aluminum assets for $4.1bn, and fell about 13% on leverage and execution worries. It is down 24.3% over three months and trades at 7.6x forward earnings — the cheapest and the weakest at once.

Rio Tinto and BHP, the two diversified majors, contributed almost nothing to the month despite carrying the highest analyst conviction in May. Teck Resources, the Canadian copper and zinc miner, rose 9.6% but is down over three months, with disruption concerns at its Quebrada Blanca operation part of the supply story lifting the metal.

USA Rare Earth, a 132-employee magnet developer building a US mine-to-magnet chain, booked $5.8m of revenue at a negative 69.8% gross margin and a $46.3m operating loss. It holds $1.5bn of cash, expects first magnet sales by end-2026 at a 600-tonne run rate, and agreed to buy Brazil's Serra Verde for about $2.8bn. At 201x trailing sales, the valuation rests on capacity that does not exist yet.

The setup

Where it stands — A 19% month in data-center metals came from four shared macro sessions; the group is down about 6% over three months. Would confirm — Freeport's third-quarter copper sales landing more than 20% above the first half, as guided. Would invalidate — New York copper falling back below $5.50/lb, removing the realized-price support under third-quarter results. Watch next — USA Rare Earth's Serra Verde close, due by end-August; third-quarter miner results from late October. Valuation — Ero at 11.3x trailing and 8.7x forward earnings against Southern Copper's 27.0x and 24.1x.

Brookfield Renewable owns the same hydroelectric dams, wind farms and solar plants twice over. Investors can hold them through a Bermuda partnership, Brookfield Renewable Partners, or through a Canadian corporation, Brookfield Renewable Corporation, created for buyers who cannot own partnership units. For years the corporation traded at a premium for that convenience. On 21 July the group said it would fold the two into a single company, exchanging each security one-for-one, with special meetings on 14 October and completion expected by year-end.

The premium has been draining out ever since. The corporation traded at 1.38x the partnership in February; on 14 August it traded at 1.02x. Over those six months the corporate shares fell 19% and the partnership units rose 9%. By the simplest trend measure — the 50-day average against the 200-day — the corporation now screens as the most broken business in this group. It is not a business event at all. Both entities reported the same second quarter on 31 July: $421m of funds from operations (FFO), up 13% year on year, and $0.62 per unit, up 11%.

What the operating quarter actually showed

Brookfield commissioned 1.3 gigawatts of new capacity and signed power purchase agreements for 2.6 GW out of its advanced pipeline. It completed $12bn of financings, including its largest-ever private placement against the Safe Harbor hydro portfolio, backed by a 20-year Google contract, and closed the quarter with $5.1bn of liquidity. A $3bn purchase of the Aypa battery platform — about $420m net to the partnership — roughly doubles battery capacity to some 6 GW and lifts the development pipeline above 80 GW. Separately, its 51%-owned Westinghouse nuclear-services arm grew segment FFO more than 60%, helped by a US Department of Energy commitment of up to $17.5bn in loan facilities for long-lead reactor equipment.

The caveat is earnings quality, and it is the one part of the bearish case that holds. Reported revenue fell 1.8% to $1.66bn, gross margin dropped to 21.3% from 58.7%, and net income has been negative in five of the past eight quarters, which makes the headline price-to-earnings ratio meaningless. Management confirmed that roughly $175m of hydro-segment "other income" was gains on developed assets and non-core sales — about 42% of the quarter's FFO — and said that contribution should scale. On the multiple that suits a leveraged generator, the partnership is the cheapest name here at 9.99x trailing enterprise value to EBITDA.

The nuclear name that raised guidance and fell anyway

Constellation Energy, a Baltimore operator of 32,400 megawatts of nuclear, gas, wind and hydro capacity, is the only member down over twelve months, at -13.4%. Second-quarter revenue rose 23% to $7.51bn. Full-year adjusted operating earnings guidance went up to $11.50–$12.50 per share from $11–$12, so the new midpoint matches the old ceiling. The company signed about 920 MW of nuclear contracts at an average 18.5-year tenor, including Walmart's first nuclear agreement, roughly 176 MW from the Dresden plant in Illinois, and a 380 MW deal with data-center landlord CyrusOne through its Calpine unit.

The shares are about 30% below their October 2025 high of $412. That is a valuation reset against rising estimates: 27.45x trailing and 24.11x forward earnings, versus the 41.31x trailing this desk recorded in early May, while consensus earnings per share climb from $11.72 this year to $17.05 in 2028. Cheaper is not cheap — Constellation is still the group's richest name at 14.74x EV/EBITDA, 3.13x book, and a trailing free-cash-flow yield of 0.3%.

The other three, and the peers

Algonquin Power & Utilities, a regulated electric, gas and water utility with about 1.27m customer connections, is where borrowing costs genuinely bite: second-quarter adjusted earnings fell to $29.2m from $33.6m, with interest expense up $9.3m. Its FFO-to-debt ratio of 11.9% sits just above S&P's 11% downgrade trigger. It trades at 0.98x book, with a forward P/E of 16.69x against 32.33x trailing — a recovery the company has not yet delivered.

AXIA Energia, the privatised former Eletrobrás and Brazil's largest generator, produced the only hard realized-price figure in the group, and it moved against the bear case: unit generation margin in the free market reached BRL 96 per megawatt-hour from BRL 73, a 32% rise, with EBITDA up 21.5%. It trades at 0.98x book and an 11.4% trailing free-cash-flow yield, and it is down 11.9% over three months. Its own guidance names the pressure: a 14% policy rate and El Niño conditions into early 2027.

The read-across is the same shape. Ormat Technologies raised 2026 guidance on revenue up 10.6% days before its trend mark turned decisively negative. Clearway Energy cut 2026 cash available for distribution to $430–470m on weak wind, but reaffirmed $2.70 per share for 2027. XPLR Infrastructure, the former NextEra Energy Partners, has suspended distributions to avoid issuing equity. Rates are not the trigger: the 10-year Treasury yield has held a 4.0–4.6% range all year.

One more number frames the month. The group averaged a 3.2% gain over 30 days, but strip two sessions from Constellation and two from the Brookfield partnership and what remains is roughly flat.

The setup

Where it stands — Four of five members are growing or raising guidance while their shares register as weak; only Brookfield's gain-dependent FFO supports the bearish read. Would confirm — The Brookfield share-class ratio settling at 1.00x through the 14 October vote, confirming the discount was mechanical. Would invalidate — Constellation guiding 2027 earnings below the $13.26 consensus, which would make the de-rating a business call. Watch next — Brookfield unitholder and shareholder meetings, 14 October 2026; closing expected in the fourth quarter. Valuation — Constellation 27.45x trailing and 24.11x forward, against 41.31x trailing in May; Brookfield 9.99x EV/EBITDA, the cheapest here.

Nearly every commercial satellite that photographs the Earth and sells the pictures belongs to one of four listed companies. Over eight days in early August, three of them opened their books. The answers had almost nothing in common.

The reports landed after a brutal summer, in which the selling had been indiscriminate: through July the whole listed space complex fell together, driven by financing and launch news rather than lost demand — a $1bn convertible raise at AST SpaceMobile, a Starship abort. The recovery since has been just as undiscriminating, and that is the problem.

Planet Labs: the growth arrived, and so did the shelf

Planet Labs runs the largest commercial imaging constellation — more than 150 satellites photographing the world's landmass daily — and sells the feed by subscription to farmers, insurers, mapmakers and defense ministries. In the quarter ended 30 April, revenue grew 42.1% to $94.2m, an acceleration from 32.6% two quarters earlier. Backlog rose 72% to more than $900m. Existing customers spent 114 cents for every dollar they spent a year earlier.

The shares fell about 24% anyway. Alongside the results Planet filed a shelf registration and launched a $1.5bn at-the-market equity offering, and guided full-year gross margin down to 52-54% from 56% with $80-95m of capital spending on its next-generation Pelican and Tanager satellites. Dilution was already running: diluted shares reached 345.5m, up 15% year on year, before the new program is drawn on.

That leaves the widest gap in the group between the business and the price. In early May this desk recorded Planet at 39.4x trailing sales and 70.2x trailing gross profit. It now trades at 24.5x sales and 44.1x gross profit, or 18.9x and 34.0x against forward estimates — a compression of roughly 38% while reported revenue sped up. Consensus models $436m of revenue this fiscal year and $570m next, with no profitable year before fiscal 2029. Planet is also the only member that has not reported since June, so its August gain rests on no fresh disclosure of its own.

BlackSky: real subscriptions, a multiple that went up

BlackSky sells on-demand satellite tasking — point a camera here, now — with AI analytics on top, mostly to defense and intelligence agencies. Second-quarter revenue rose 50.1% to $33.3m, reversing a 29.7% decline the quarter before. Subscription revenue hit a $100m annualized run rate, and adjusted EBITDA was $4.7m, a 14.2% margin, against -$2.8m a year earlier. The company reaffirmed 2026 guidance of $130-150m, raised $150m through an equity offering and won an eight-figure National Reconnaissance Office (NRO) award to accelerate its AROS mapping system.

It is also the only one of the four that is dearer than in May — 11.6x trailing sales against 10.87x — despite shares 26% lower over three months, because trailing gross profit shrank. One caveat: the vendor data records second-quarter gross profit as -$7.8m, identical to operating income and implausible against margins above 70% in prior quarters, which inflates the gross-profit multiple. The concentration to watch is elsewhere: international customers now account for 80% of funded backlog, with US business flat.

Satellogic: the record quarter Portugal paid for

Satellogic builds compact high-resolution imaging satellites and sells the data to governments for border security, agriculture and disaster response. Revenue rose 258.5% to $15.9m, gross margin reached 82.3%, and operating income turned positive for the first time, at $0.27m.

The mix is the catch. Europe supplied 58% of the quarter, principally an $18m contract to deliver satellites to Portugal's CEiiA — a hardware sale, not a subscription. Recurring data and analytics revenue was $7.1m, though that grew 54% sequentially. The company reported $80.7m of non-cancellable remaining performance obligations and $112.8m of cash. Against that: diluted shares rose 45.9% year on year to 150.6m, the heaviest dilution here; the chief financial officer departs on 21 August; and its historically barter-based arrangement with Palantir has not been renewed for cash. The multiple has roughly halved since May, to 25.0x trailing sales from 49.8x.

Spire: revenue that is actually shrinking

Spire Global operates satellites tracking ships, aircraft, weather and objects in orbit, and sells the data to governments and businesses. Reported revenue fell 5.9% to $18.0m, gross margin compressed to 34.1% from 48.9%, and adjusted EBITDA was -$8.6m. The 16% growth management cited requires excluding the divested maritime unit. It has $92m of cash, no debt, says 85% of full-year guidance is contracted, and on 14 August won a $3.7m National Oceanic and Atmospheric Administration contract for weather data, with a larger renewal in negotiation. Its multiple slipped only from 8.59x sales to 7.28x — a modest de-rating against genuinely falling revenue.

What the month was

From 17 July to 14 August the four gained 29.0% on an equal-weighted basis. Weighted by size it is 15.3%, because Planet is 77% of the group's $10.7bn and moved least. The gain was not one gap day — no session exceeded 13.5% — but it was concentrated: the four averaged -4.2% to 31 July, then 34.6% after. Remove each name's two best days and Planet turns to -1.6% and Spire to -2.9%, while BlackSky holds 14.7% and Satellogic 21.1%. Over three months the group is down 30.7%, and all four sit 40-52% below their 2026 highs; the 50-day averages of Planet, BlackSky and Satellogic crossed below their 200-day lines in mid-August, describing the crash rather than the bounce.

Underneath sits a floor that is contractual rather than episodic: the NRO's Electro-Optical Commercial Layer, awarded in 2022 to Maxar, Planet and BlackSky, runs ten years — five guaranteed, five in options.

The setup

Where it stands — A post-earnings bounce inside a much larger three-month drawdown, with only Planet and BlackSky showing growth in recurring revenue.

Would confirm — Satellogic's data-and-analytics line growing again in Q3 without another one-off satellite-delivery contract in the mix.

Would invalidate — Planet's next quarter growing below 30% or backlog falling, which would make the 42% acceleration a peak.

Watch next — Planet reports fiscal Q2 in early September; Satellogic's Merlin constellation targets a first launch in October 2026.

Valuation — Planet at 24.5x trailing sales and 18.9x forward, against 39.4x recorded here in early May.

The federal tax credit that covered nearly a third of the cost of an American home solar system lapsed at the end of last year, and the industry has spent 2026 discovering what demand looks like without it. Enphase's management says US permits for residential systems are running about 30% below prior-year levels. The Solar Energy Industries Association forecasts a 21% decline in the US residential market this year, and BloombergNEF expects installations of 4.1 gigawatts, the lowest in five years.

The two companies that sell the power electronics into those rooftops reported opposite quarters into that backdrop.

One is growing, one is not

SolarEdge, an Israeli maker of string inverters and per-panel power optimizers, reported June-quarter revenue of $346.2m, up 19.6% year on year and 11.5% from March. Gross margin was 27.5% against 11.1% a year earlier. Its operating margin narrowed from -39.9% to -4.6%, and non-GAAP operating income of $10.2m was the first in nearly three years. European revenue of $154.4m rose 36% sequentially and more than doubled year on year, as Dutch and German homeowners bought storage ahead of the end of net metering.

Enphase, the Fremont, California company whose semiconductor microinverters convert power at each individual solar module, reported revenue of $291.9m, down 19.6% — its third consecutive quarter of roughly that size. Its profits went the other way: gross profit rose 2.7% and operating income 39.2%, on a 60.0% gross margin. But $84.3m of the quarter's revenue was "safe harbor" — equipment bought early to lock in expiring credits — against $34.5m in March. Ex-safe-harbor, the core business fell from roughly $248m to roughly $208m. Management said US sell-through was down 34% year on year.

The multiple is on the wrong company

Neither company has clean earnings to value against, so gross profit is the honest anchor. Enphase trades at 8.58x trailing gross profit and 9.62x forward — the forward figure is higher, because consensus models fiscal 2026 revenue 19.3% below 2025 and earnings per share down 27.7%. SolarEdge trades at 6.68x trailing and 6.65x forward, essentially flat, with consensus revenue growth of 13.6% this year and 11.7% next. Both have de-rated hard from mid-May, when Enphase stood at 14.55x and SolarEdge at 16.09x.

SolarEdge holds $601.6m of cash against a $1.97bn market value, generated $3.1m of free cash flow in the quarter and guides to positive free cash flow for the year. Enphase holds $937.7m, with no convertible maturity until March 2028.

The caveat that moved the stock is real. SolarEdge guided current-quarter revenue to $310-340m against expectations near $370m, a 12% shortfall, citing European seasonality and slow US tax-equity funding held up by unresolved foreign-content rules governing which systems qualify for the surviving commercial credit.

The chart is a round trip, not a collapse

Most of the damage is one day. SolarEdge lost 28.1% on 5 August on 13.3m shares against a 2-4m norm. Exclude that three-session reaction and its 30-day return is -8.8%, against Enphase's -8.1%. Over six months Enphase is down 6.9% and SolarEdge 8.8%; both are higher over twelve. What actually happened is that a May-June rally on speculative artificial-intelligence datacenter optionality — both firms are developing high-voltage power conversion hardware, with volume revenue targeted for 2028 — nearly doubled each stock and then unwound. Enphase has risen 15.4% off its 29 July low.

The installers underneath them are in worse shape. Sunrun, the largest US residential solar lessor, added 31% fewer subscribers year on year last quarter and cut its full-year value guidance; its shares are down 46.6% in six months. Third-party leases, which still access the commercial 48E credit through 2027, are the industry's workaround, and Enphase's PROPEL financing platform is running about 200 originations a week toward a year-end target of 500.

The setup

Where it stands — SolarEdge's business is improving on every line and its multiple is a third of May's; Enphase's is shrinking while carrying the higher forward multiple. Would confirm — SolarEdge lands the current quarter at or above the $325m guidance midpoint with non-GAAP gross margin inside 22-26%. Would invalidate — Enphase core revenue excluding safe harbor stabilizes above $210m while SolarEdge margin slips back below 22%. Watch next — Third-quarter results in late October, and Treasury's foreign-content safe-harbor tables, due by 31 December 2026. Valuation — Enphase 8.58x trailing, 9.62x forward gross profit, from 14.55x in May; SolarEdge 6.68x and 6.65x, from 16.09x.

Inside a current AI server rack, electricity arrives as alternating current, is rectified, stepped down and pushed along a 54-volt busbar before a final conversion at the graphics processor. NVIDIA's proposed replacement carries 800 volts of direct current from the row into the rack itself, stripping out conversion stages and a great deal of copper. It is a genuine architectural change, and a small group of American component makers is positioned for it.

It is also, on every one of these companies' own guidance, a 2027 event. Navitas Semiconductor, which makes gallium-nitride and silicon-carbide power chips, told investors on 27 July that the 800-volt sidecar rack inflection arrives around mid-2027. Vicor, an Andover, Massachusetts maker of modular DC-DC power converters, guides production of its second-generation vertical power delivery modules to late in the fourth quarter of 2027. Ideal Power, a 17-person Austin company developing a bi-directional solid-state switch, tied its pipeline explicitly to "800-volt DC power architecture adoption beginning H2 2027."

What is actually in the numbers

Bel Fuse, a Jersey City manufacturer of magnetics, circuit protection and board-mount power modules, is the one unambiguous grower. Second-quarter revenue rose 25.2% to $210.7m, gross margin widened 120 basis points to 39.9%, and operating income grew 47.4% — faster than sales. It has now reported six straight quarters of positive book-to-bill. But its biggest single contributor was aerospace and defense, where sales rose 28.4% to $66.5m, ahead of the roughly $58m data-center line. The data business did grow 55% year on year, helped by the March acquisition of connector maker dataMate. Bel guides the third quarter to $205m-225m.

Ultralife, an Industrials-classified maker of lithium batteries and military communications gear with a market value near $125m, saw revenue fall 1.3% to $47.9m as its battery segment shrank on oil-and-gas weakness. Its backlog is the story: $117.5m at 30 June, up 39%, and roughly $130m by early August, driven by the US Army's next-generation command-and-control program through prime contractor L3Harris. Half the 500-basis-point gross margin gain came from a one-time $1.1m tariff refund. Nothing in that is power architecture.

Vicor grew; the shares did not

Vicor's headline revenue of $143.4m looks flat, up 1.6%, but the year-ago quarter contained a $45m patent settlement. Strip it and the core product-and-royalty line grew 49.3%. Backlog rose 26% sequentially to $379.7m and 145% from a year earlier. Management raised its long-term target to $2.5bn of revenue at a 70% gross margin, from $1bn and 65%. Gross margin reached 58.0%.

The shares fell 9.8% over the month and 14.2% over three months, and sit 38.2% below their high of the past quarter. Price-to-gross-profit has compressed from 61.8x in mid-May to 39.6x trailing and 31.2x forward, while market value fell from $14.4bn to $10.6bn. That is the clearest gap in the group between a business and its price — with the qualifier that royalties reached $30.4m, a fifth of core revenue, and 68.3x forward earnings is not cheap in absolute terms.

Navitas runs the other way. Revenue fell 27.3% to $10.53m, the fourth consecutive year-on-year decline; gross margin was negative at -9.5%; the net loss was $228.2m. It debuted an 800V-to-6V power board at NVIDIA's GTC 2026, but STMicroelectronics and Texas Instruments announced supporting parts at the same show — the socket is contested. Wolfspeed sued Navitas on 7 July over five patents covering its entire product range, and Renesas followed with a trade-secret suit on 22 July. Navitas raised $373m in the quarter at $21.89 a share, about 51% above the mid-August price of $14.45.

Ideal Power booked $5,800 of revenue against a $3.62m operating loss, on an $85.9m market value of which roughly half is cash. Its prototype solid-state circuit breaker for an unnamed hyperscaler is due at the end of the fourth quarter.

The month was three sessions

The group is up about 9.5% on an equal-weight basis over 30 days, but it is down 3.2% over 90, and the July collapse was severe — Bel Fuse's two share classes each fell more than 16% on 2 July, Navitas 21.0% on 28 July. Remove each name's two best single sessions and the month becomes roughly -10.6%. Three shared rebound days did the work, and they line up with a macro reset: chip stocks shed more than $1 trillion in the July selloff, then Bank of America lifted its hyperscaler capital-spending expectation above $1.2 trillion for the coming year.

Valuations sit in four places. Bel Fuse trades at 30.5x forward earnings for the B shares and 25.9x for the A, against 72.5x trailing, and 11.0x forward gross profit — roughly a third of Vicor's multiple, on lower margins. Ultralife is at 8.7x forward earnings and 0.94x book. Navitas is at 80x forward sales with no positive gross profit; Ideal Power at 107x forward sales on $800k of consensus 2026 revenue.

The setup

Where it stands — The group's growth today comes from defense and legacy industrial demand, while the 800-volt data-center revenue it is named for begins in 2027.

Would confirm — Navitas hitting its $13.5m third-quarter guide with gross margin turning positive, and Vicor's backlog rising again from $379.7m.

Would invalidate — Bel Fuse defense growth slowing below its data-center line, or Vicor's book-to-bill dropping under 1.0.

Watch next — Third-quarter results across the six in late October and early November 2026; Ideal Power's hyperscaler breaker prototype due by 31 December.

Valuation — Vicor at 39.6x trailing and 31.2x forward gross profit, against 61.8x trailing in May; Bel Fuse at 11.9x and 11.0x.
