Seagate Technology Holdings plc (NASDAQ: STX) is pulling back on 23 December 2025 after a powerful 2025 run—yet the stock remains one of the market’s most closely watched “AI infrastructure” plays in the data storage space, as investors weigh three near-term catalysts: Nasdaq-100 membership, a late-December dividend, and a growing stack of bullish Wall Street price-target revisions.
As of the latest available market read on 23 December, STX was trading around $278 (down about 1.7% on the day), with an intraday range roughly $275–$284 and a market capitalization near $59B. [1]
Below is a full roundup of the current news, forecasts, and notable analysis relevant to STX as of 23.12.2025, plus what investors are watching next.
What’s moving Seagate stock on 23 December 2025
1) Nasdaq-100 inclusion is now live—and can reshape flows
One of the biggest “structural” developments for Seagate shares in December is that Seagate has been added to the Nasdaq-100, with the index changes taking effect before market open on 22 December 2025. [2]
Why it matters:
- Passive demand and rebalancing effects: Index inclusion can increase mechanical buying (and sometimes short-term volatility) as Nasdaq-100-linked funds and strategies adjust.
- Visibility boost: Membership tends to raise a company’s profile with global allocators, especially those benchmarking against large-cap tech-heavy indices.
Reuters specifically listed Seagate Technology among the new entrants and noted the changes were expected to take effect on December 22. [3]
2) Profit-taking after a major surge
Seagate’s 2025 rally has been dramatic, and pullbacks are increasingly being framed as profit-taking after outsized gains rather than a single-company “breakdown” story. Multiple market commentaries in recent weeks have referenced STX’s 2025 surge (well above 200% at points) as the context behind sharper down days. [4]
A same-day (23 Dec) Trefis note also highlights how quickly STX has moved recently—pointing to a strong advance over a short trading window, which can raise the odds of a consolidation phase even if the longer-term story remains intact. [5]
3) Dividend timing: ex-dividend date is 24 December 2025
Another near-term focus is Seagate’s next quarterly dividend. Nasdaq’s dividend history page lists an ex-dividend date of 24 December 2025 for a $0.74 dividend. [6]
Seagate’s own investor materials indicate the dividend is payable on 9 January 2026 to shareholders of record as of 24 December 2025, and the company previously said it increased the quarterly cash dividend to $0.74. [7]
The fundamental backdrop: Seagate’s AI-storage narrative remains the core driver
Q1 FY2026 results: revenue growth, record margins, and strong cash generation
Seagate’s most recent reported quarter (fiscal Q1 2026, ended 3 October 2025) remains central to the bull case:
- Revenue: $2.63B
- Non-GAAP gross margin: 40.1% (record levels cited by the company)
- Non-GAAP EPS: $2.61
- Free cash flow: $427M
- Capital return: $182M through dividends and share repurchases
- Dividend increase: quarterly dividend lifted to $0.74 [8]
Management also emphasized AI-driven storage demand and said it has visibility into sustained strength, highlighting that its Mozaic HAMR products are qualified with five of the world’s largest cloud customers. [9]
Guidance and demand visibility: what the company and Reuters reported
For fiscal Q2 2026, Seagate guided to:
- Revenue: $2.70B ± $100M
- Non-GAAP diluted EPS: $2.75 ± $0.20 [10]
Reuters’ coverage tied the outlook to cloud providers ramping hardware spending for generative AI workloads, with Seagate benefiting as a supplier of storage used to hold vast amounts of data. [11]
Product/technology momentum: HAMR and high-capacity drives
Seagate has been positioning HAMR (heat-assisted magnetic recording) as a key enabler for scaling HDD areal density and shipping higher-capacity drives into hyperscale and enterprise environments.
In mid-2025, the company announced global channel availability of up to 30TB Exos and IronWolf Pro HDDs built on its Mozaic 3+ platform and powered by HAMR, explicitly framing the launch around rising AI-driven storage needs. [12]
Wall Street forecasts and analyst price targets for STX
Consensus view: “Moderate Buy,” with a wide target range
MarketBeat’s consolidated snapshot as of 23 December 2025 shows:
- Consensus rating: Moderate Buy
- Analyst count: 26 ratings
- Average 12-month price target:$293.13
- High target: $465
- Low target: $150 [13]
That target spread is important: it signals meaningful disagreement on how durable Seagate’s current margin and demand environment will be.
Recent notable target increases: Morgan Stanley and Citi
Two widely circulated updates in December:
- Morgan Stanley raised its price target on Seagate to $337 from $270 and maintained an Overweight rating, per a TheFly note carried by TipRanks. [14]
- Citi raised its price target to $320 from $275 and kept a Buy rating, citing a supportive supply/demand backdrop, pricing momentum, and demand visibility “through 2027,” also via TheFly/TipRanks. [15]
MarketBeat’s recap of the Citi move also highlights how aggressively bullish some targets have become (including targets reaching into the $400s from certain firms), underscoring how much of the Street’s upside case rests on sustained AI-driven storage demand and continued pricing power. [16]
A 23 December 2025 risk-focused take: can STX withstand a pullback?
Not all analysis is purely momentum-driven. A Trefis note published 23 December 2025 directly raises the question of whether Seagate’s stock is “built to withstand a pullback,” pointing to the stock’s sharp near-term run, relatively expensive valuation metrics, and historical drawdowns that were deeper than the broader market in some prior downturns. [17]
This kind of work tends to resonate when a stock has already delivered huge gains: even bullish investors often start shifting from “is the story real?” to “how much downside can I tolerate if the trade gets crowded?”
Balance sheet and dilution watch: exchangeable notes activity
A less headline-grabbing—but still relevant—thread for equity investors is Seagate’s work on its exchangeable notes.
In November 2025, disclosures around privately negotiated exchanges indicated Seagate exchanged $500 million principal amount of 3.50% exchangeable senior notes due 2028 for a mix of cash and ordinary shares, in a transaction that can affect leverage, cash, and potential dilution math. [18]
Separately, Seagate’s fiscal Q1 2026 materials explicitly note that its guidance includes the net dilutive impact from the exchangeable senior notes due 2028. [19]
Sentiment check: short interest and positioning
Short interest is not extreme, but it’s not negligible either. MarketBeat’s short-interest page (updated 23 December 2025) lists:
- Short interest: ~12.67 million shares
- Short % of float: ~5.98%
- Days to cover: ~4.2 [20]
That level can add fuel to sharp moves in either direction—especially around earnings—without necessarily signaling a “high short squeeze” setup by itself.
What investors are watching next
1) The next earnings date window (late January 2026)
Earnings-date calendars vary, but multiple listings point to late January 2026 as the next reporting window. Nasdaq’s earnings page includes an estimate around 20 January 2026, while other trackers also cluster around the same period. [21]
Given how much of the bull case rests on pricing, margins, and hyperscale demand, that next report is likely to be the biggest volatility event on the calendar.
2) Whether guidance holds up—and whether “visibility through 2027” is real in bookings
The most important operational questions for STX into 2026:
- Do hyperscalers keep ordering high-capacity nearline drives at the pace implied by current guidance?
- Does Seagate sustain record-level margins, or do competitors and supply responses pressure pricing?
- How smoothly does HAMR ramp as volumes rise?
3) Nasdaq-100 after-effects
Index membership is not a fundamental catalyst, but it can shift the shareholder base. Watch for:
- changes in volume/liquidity,
- potential re-rating dynamics,
- and whether STX’s volatility profile changes after the reconstitution-driven flows fade.
4) Dividend mechanics
With Nasdaq listing an ex-dividend date of 24 December 2025 and the company pointing to a 9 January 2026 payment date, dividend-related positioning could be a short-term technical factor—particularly in a stock that has already run hard. [22]
Bottom line for Seagate (STX) stock on 23 December 2025
Seagate stock’s near-term story is being shaped by a mix of index inclusion, dividend timing, and analyst enthusiasm, layered on top of a bigger narrative: AI is driving a step-change in data creation, and cloud players need scalable, cost-efficient storage—an environment where Seagate argues HAMR-enabled, high-capacity HDDs are increasingly strategic. [23]
At the same time, the stock’s huge 2025 gains raise the bar: valuation and drawdown resilience are now part of the debate, not just “growth momentum.” [24]
