"Great Quarter?" Wrong answer, Sandisk

Presented by

The market closed lower Thursday as the U.S.-Iran conflict and a 3.6% jump in crude pushed investors toward energy and away from risk. Oil majors carried the winners’ board, while banks and growth names took the defensive hit.

Earnings delivered the sharper warning: good numbers were not enough when outlooks or margins missed the story investors had already priced. Western Digital, SanDisk, Celsius, and Trade Desk all learned some version of the same lesson, while MARA’s $611.3M loss made the punishment easier to understand.

Stocktwits traders kept buying weakness anyway, with bullish attention clustering around Trade Desk, Applied Optoelectronics, and Red Cat. The split was clean: blue chips drove the indexes, but retail’s loudest arguments were happening farther down the market.

AFTER THE BELL
MARA’s $611M Bitcoin Hangover 🤕

MARA Holdings, the Bitcoin miner expanding into AI infrastructure, reported a massive second-quarter loss Thursday as falling revenue and a digital-asset markdown torched results. And here we thought everyone was shifting over to data center rentals!

The RIP: $MARA ( ▼ 5.25% )  rose 0.9% after hours after falling 5.2% in regular trading. Revenue fell 27% to $174.9M vs. $209.4M expected, while the company lost $1.60 per share vs. a $0.17 profit expected. A $343M digital-asset fair-value loss helped drive the $611.3M net loss.

Bitcoin-miner holders got the ugly contradiction: energized hashrate rose 22%, but revenue fell 27% and BTC holdings shrank 29%. MARA is pushing into AI and high-performance computing as planned capacity expands from 1.9GW toward 4.8GW. Next quarter, watch whether those new workloads produce revenue; more power without better economics is just a larger electric bill.

The Open Internet Closes 📉

The Trade Desk, the programmatic advertising platform for brands and agencies, missed second-quarter expectations Thursday and issued a third-quarter forecast far below Wall Street’s estimate. Shares cratered after hours as the slowdown went from worrying to difficult to explain away.

The RIP: $TTD plunged 25% after hours. Adjusted EPS was $0.34 versus $0.40 expected, while revenue rose 3% to $715M versus $751M expected. Adjusted EBITDA fell to $241M from $271M one year earlier.

The third-quarter forecast is the fire alarm: Trade Desk expects at least $650M in revenue versus the $807M analysts anticipated. Management gets one quarter to prove its platform upgrades can stop the deceleration. Revenue growth and adjusted EBITDA margin must stabilize, or the open-internet story starts looking like lost market share with better branding.

The Next Breakout Might Be in Your Pocket

Everyone’s hunting for the next Unicorn.

The type of “category disruptor” that grows fast and turns early believers into big winners.

60,000+ investors think that Mode Mobile could be one of those rare finds.

Americans spend 4 ½ hours on their phones daily, and Mode Mobile is monetizing that screentime. With $1B+ earned by over 490M customers and 32,481% revenue growth, Mode’s EarnPhone is turning smartphones into income generating assets.

Their previous raises sold out, and the company is now offering pre-IPO shares at $0.52/share with up to 20% bonus. But their share price is changing on August 14.

Being early is everything, and this window is open for a few more days.

STOCKS
Celsius Loses Its Fizz 🥤

Celsius Holdings, the energy-drink maker behind CELSIUS, plunged Thursday after second-quarter revenue and adjusted earnings missed Wall Street expectations while its flagship brand weakened.

The RIP: $CELH fell 18.5% to $23.77 on 4.8x recent volume. Adjusted EPS was $0.36 vs. $0.42 expected, while revenue rose 11% to $817.9M vs. $870.1M expected. CELSIUS retail sales fell 2%, while Alani Nu climbed 56%.

Holders now own a three-brand turnaround, not a one-brand growth story, with Alani Nu carrying declines at CELSIUS and Rockstar. Management is tightening assortments and execution as it tries to return CELSIUS to sustainable growth. Next quarter, watch flagship retail sales and gross margin; another decline would make Alani Nu look less like diversification and more like life support.

Remember: Perfect Wasn’t Good Enough 💾

Western Digital and SanDisk, the hard-drive and flash-memory suppliers feeding AI data centers, sold off Thursday after their strong Wednesday reports collided with outlooks that failed to clear towering expectations.

The RIP: $WDC ( ▼ 13.03% )  tumbled 13%, while $SNDK ( ▼ 6.81% )  fell 6.8%. Western Digital’s revenue rose 44% to $3.75B vs. $3.7B expected, with adjusted EPS of $3.56. SanDisk delivered $39.25 EPS vs. $34.96 expected on $8.96B in revenue, topping the $8.48B estimate.

Western Digital expects roughly $4.1B in first-quarter revenue, 9.4% sequential growth, and a 55.5% adjusted gross margin. SanDisk guided revenue to $10.3B-$10.8B, implying another 17.7% sequential increase at the midpoint, and authorized a $14B buyback. Apparently, “still booming” is bearish when investors paid for “somehow booming faster.”

AI-storage bulls should notice the split: Seagate climbed 4%, while Micron finished roughly flat, so this was not a blanket rejection of the theme. Western Digital was the risk leg because its outlook trailed peer expectations, while SanDisk confirmed demand but showed the cost of a sky-high bar. Next quarter, watch whether Western Digital hits its margin target and whether SanDisk’s pricing-led growth holds.

The earnings season is going well for the S&P 500, and believe it or not is soon coming to an end already!

$CRSR +16% | Corsair: One refund did not explain all of the beat

24.3K WATCHERS · NEUTRAL · HIGH ACTIVITY

Corsair posted a record 33.2% gross margin and $30.8M in adjusted EBITDA, though a tariff refund supplied $14.3M of that total. Results still cleared guidance without the benefit, leaving the neutral room to decide whether better product mix can keep powering the turnaround after the accounting boost disappears.

$AAOI -7% | Applied Optoelectronics: The selloff made bulls louder

24.2K WATCHERS · EXTREMELY BULLISH · HIGH ACTIVITY

Applied Optoelectronics delivered record Q2 revenue of $191.9M as 800G product volume more than doubled sequentially, then guided Q3 revenue to $255M–$290M. The extremely bullish stream is treating the drop as an expectations reset, but production capacity remains the number separating a monster AI-optics ramp from another delayed promise.
