US SEC Trading Suspension Halt Orders — October 29, 2026

USA Trading Suspensions

By Gunpowder Editorial ·

4 high priority 4 total filings analysed

Executive Summary

The October 29, 2026 US trading-suspension stream is dominated by listing-standard stress: three of four filings involve Nasdaq compliance failures or delistings, while one is a voluntary NYSE-to-TXSE transfer.

The most acute events are Glucotrack's confirmed delisting (trading suspended at the open on October 30, 2026) and Propanc Biopharma's imminent delisting (effective November 2, 2026 absent an appeal by October 30, 2026), both driven by the $1.00 minimum bid price rule and complicated by prior reverse splits. Greenland Energy Company (Pelican Holdco) remains listed but has an outstanding majority-independent-director deficiency with a cure period running to the earlier of its next annual meeting or October 20, 2027, though its audit committee deficiency was cured on October 27, 2026. Cullen/Frost's move is fundamentally different: a board-authorized, voluntary transfer of both its common and Series B preferred listings to the Texas Stock Exchange, with NYSE trading ending November 11 and TXSE trading beginning November 12, 2026, under the same symbols. Across the stream, the common thread is exchange-listing risk management: micro-caps face forced delisting and OTC migration, while a large Texas bank is opting into a regional exchange for strategic reasons. Near-term catalysts are concentrated in the next 72 hours (Glucotrack suspension, Propanc appeal deadline) and the next two weeks (Cullen/Frost listing transition).

Investment Signals (10)

  • Glucotrack (GCTK) (BEARISH)
    ▲

    Nasdaq Hearings Panel determined to delist; closing bid was $0.87 on October 14, 2026, below the $1.00 exception threshold, and trading is suspended at the open on October 30, 2026 — a definitive liquidity event for current holders

  • Nasdaq minimum bid price notice received October 23, 2026; delisting effective November 2, 2026 unless the company appeals by October 30, 2026 — binary near-term outcome with appeal stay potential

  • Ineligible for the standard 180-day compliance period because it already effected a reverse split within the prior year, signaling prior listing distress and limiting remediation options

  • Greenland Energy (GLND) (BULLISH)
    ▲

    Audit committee deficiency under Rule 5605(c)(2)(A) cured on October 27, 2026 with the appointment of independent director Melanie Furlan, joining Scott Wollney and Carol Craig — partial de-risking of the Nasdaq listing

  • Greenland Energy (GLND) (BEARISH)
    ▲

    Majority independent director deficiency under Rule 5605(b)(1) remains outstanding following Roderick McIllree's October 20, 2026 resignation; cure period extends to the earlier of the next annual meeting or October 20, 2027

  • Voluntary transfer of common and 4.450% Series B preferred depositary shares from NYSE to TXSE, retaining symbols CFR and CFR.PrB; NYSE trading ends November 11, 2026 and TXSE begins November 12, 2026 — no fundamental change to the business [NEUTRAL/BULLISH]

  • Board-authorized exchange transfer is explicitly not a delisting for failure to meet listing standards, distinguishing it from the Nasdaq compliance failures in the same stream

  • Company states there is no immediate effect on its Nasdaq listing, with common stock (GLND) and warrants (GLNDW) continuing to trade on the Nasdaq Global Market

  • Glucotrack (GCTK) (BEARISH)
    ▲

    Company intends to apply for quotation on the OTC Markets OTCID tier upon suspension, but provides no assurance of that transition — potential liquidity degradation for holders

  • Stream-wide (BEARISH)
    ▲

    Three of four filings are negative-sentiment listing-compliance events, versus one neutral voluntary transfer, indicating a risk-off micro-cap listing environment in this period

Risk Flags (9)

  • Glucotrack (GCTK) [HIGH RISK]
    ▼

    Nasdaq Hearings Panel exception was conditioned on maintaining a closing bid price of at least $1.00 for each trading day through November 9, 2026; the $0.87 close on October 14, 2026 breached that condition and triggered delisting

  • Glucotrack (GCTK) [HIGH RISK]
    ▼

    Trading suspension at the open on October 30, 2026 and expected Form 25 filing to delist and deregister under Section 12(b) — immediate loss of exchange liquidity and reduced institutional eligibility

  • Propanc Biopharma↓ [HIGH RISK]
    ▼

    Delisting effective November 2, 2026 absent an appeal by October 30, 2026; the appeal deadline is the binding near-term risk event

  • Propanc Biopharma↓ [HIGH RISK]
    ▼

    Company acknowledges delisting would reduce liquidity, shrink its investor base, limit access to public capital markets, and impair its ability to grant equity incentives

  • Propanc Biopharma↓ [HIGH RISK]
    ▼

    Prior reverse stock split within the last year makes the company ineligible for the standard 180-day cure period, reflecting a history of bid-price non-compliance

  • Greenland Energy (GLND) [MEDIUM-HIGH RISK]
    ▼

    Majority independent director deficiency remains outstanding after McIllree's resignation; failure to cure by the applicable deadline could result in a Nasdaq delisting determination

  • Greenland Energy (GLND) [MEDIUM RISK]
    ▼

    Cure period is tied to the next annual shareholders' meeting; if the meeting is held before April 19, 2027, compliance must be evidenced by April 19, 2027, creating a hard deadline

  • Cullen/Frost (CFR)↓ [MEDIUM RISK]
    ▼

    NYSE-to-TXSE transfer introduces execution and liquidity-transition risk around November 11-12, 2026, including potential index-membership and investor-mandate implications

  • Stream-wide [MEDIUM RISK]
    ▼

    Micro-cap biotech names (Propanc, Glucotrack) are disproportionately exposed to $1.00 bid-price delisting mechanics, a structural overhang for the sector

Opportunities (9)

  • Propanc Biopharma↓ (OPPORTUNITY)
    ◆

    Appeal by October 30, 2026 would stay the delisting pending the Panel's decision, creating a binary catalyst window for event-driven traders

  • Propanc Biopharma↓ (SPECULATIVE OPPORTUNITY)
    ◆

    Company believes it has cured the deficiency; if the Panel accepts that view, the stock could avoid delisting and re-rate from distressed levels

  • Glucotrack (GCTK) (SPECULATIVE)
    ◆

    Planned OTCID quotation provides a potential post-suspension trading venue; however, no assurance is provided, so this is a high-risk liquidity event rather than a clean opportunity

  • Greenland Energy (GLND) (OPPORTUNITY)
    ◆

    Audit committee cure on October 27, 2026 removes one of two Nasdaq deficiencies; resolution of the majority-independent-director issue would fully de-risk the listing

  • Greenland Energy (GLND) (OPPORTUNITY)
    ◆

    Common stock and warrants (GLND, GLNDW) continue trading on the Nasdaq Global Market with no immediate effect, preserving liquidity during the cure period

  • Cullen/Frost (CFR)↓ (OPPORTUNITY)
    ◆

    TXSE listing beginning November 12, 2026 under the same symbols (CFR, CFR.PrB) may attract Texas-focused and regional-exchange flows; the voluntary nature signals confidence in the transfer

  • Cullen/Frost (CFR)↓ (OPPORTUNITY)
    ◆

    The 4.450% Series B preferred depositary shares transfer alongside the common, preserving the income vehicle for preferred holders through the exchange change

  • Cullen/Frost (CFR)↓ (OPPORTUNITY)
    ◆

    Board-authorized transfer is a strategic, not distress-driven, event — any NYSE-exit-related selling pressure around November 11 could create an entry point for long-term holders

  • Stream-wide (SPECULATIVE OPPORTUNITY)
    ◆

    Distressed micro-cap delisting names may attract specialist OTC/market-making interest as they migrate to OTCID or alternative venues

Sector Themes (6)

  • Micro-Cap Bid-Price Delisting Wave (BEARISH THEME)
    ◆

    Two of four filings (Propanc, Glucotrack) are $1.00 minimum bid price failures under Nasdaq Rule 5550(a)(2), both with prior reverse splits, highlighting structural pressure on sub-$1 micro-caps

  • Reverse-Split Ineligibility Trap [RISK THEME]
    ◆

    Propanc's prior reverse split within one year disqualified it from the standard 180-day cure period under Rule 5810(c)(3)(A)(iv), a recurring trap for serial reverse-splitters

  • Nasdaq Independence-Standard Scrutiny
    ◆

    Greenland Energy's dual deficiencies under Rules 5605(b)(1) and 5605(c)(2)(A) show board-composition compliance is an active listing-risk vector, though the audit committee cure was swift [NEUTRAL/RISK THEME]

  • Regional Exchange Migration (STRATEGIC THEME)
    ◆

    Cullen/Frost's voluntary NYSE-to-TXSE transfer is an early example of a large-cap bank choosing a regional exchange, potentially foreshadowing broader listing-venue competition

  • OTC Fallback Strategy (BEARISH THEME)
    ◆

    Glucotrack's planned OTCID application reflects the standard fallback path for delisted micro-caps, though lack of assurance underscores the fragility of OTC transitions

  • Event-Driven Listing Compliance Calendar (TIMING THEME)
    ◆

    The stream clusters hard dates — October 30 (Glucotrack suspension, Propanc appeal deadline), November 2 (Propanc delisting effective), November 11-12 (Cullen/Frost transition) — creating a dense catalyst window

Watch List (8)

  • Appeal deadline October 30, 2026 — filing an appeal stays delisting pending Panel decision; failure to appeal triggers delisting effective November 2, 2026

  • Glucotrack (GCTK)
    👁

    Trading suspension at the open on October 30, 2026; watch for Form 25 filing and any OTCID application update

  • Greenland Energy (GLND)
    👁

    Majority independent director deficiency cure — monitor board appointments ahead of the next annual meeting; compliance must be evidenced by April 19, 2027 if the meeting is held before that date

  • NYSE trading ends at market close November 11, 2026; TXSE trading begins at market open November 12, 2026 — watch for liquidity and index-membership effects

  • Series B preferred depositary shares transfer to TXSE alongside common; monitor preferred pricing around the transition

  • Nasdaq Hearings Panel
    👁

    Watch for any Propanc appeal decision and Glucotrack Form 25 confirmation

  • Watch for any additional 8-K disclosures on board composition or Nasdaq correspondence

  • Stream-wide
    👁

    Monitor for follow-on delisting notices among micro-caps with recent reverse splits as the $1.00 bid rule continues to bite

Filing Analyses (4)
CULLEN/FROST BANKERS, INC. 8-K neutral materiality 6/10

29-10-2026

Cullen/Frost Bankers notified the NYSE on October 29, 2026 of its intention to voluntarily delist its Common Stock (CFR) and 4.450% Series B Preferred Depositary Shares (CFR.PrB) and transfer both listings to the Texas Stock Exchange (TXSE). NYSE trading is expected to end at market close on November 11, 2026, with TXSE trading beginning at market open on November 12, 2026, retaining the same symbols. The move was board-authorized and is a voluntary exchange transfer rather than a delisting for failure to meet listing standards.

Pelican Holdco, Inc. 8-K negative materiality 6/10

29-10-2026

Greenland Energy Company (GLND) disclosed in an 8-K that following the October 20, 2026 resignation of director Roderick McIllree, it notified Nasdaq on October 23, 2026 that it fell out of compliance with Nasdaq Listing Rule 5605(b)(1) (majority independent director requirement) and Rule 5605(c)(2)(A) (three independent directors on the audit committee). Nasdaq issued a letter dated October 28, 2026 granting a cure period until the earlier of the next annual shareholders' meeting or October 20, 2027 (or April 19, 2027 if the annual meeting is held before that date); however, the audit committee deficiency was already cured on October 27, 2026 when the Board appointed independent director Melanie Furlan, joining Scott Wollney and Carol Craig. The company says there is no immediate effect on its Nasdaq listing, with common stock (GLND) and warrants (GLNDW) continuing to trade on the Nasdaq Global Market, though the majority independent director deficiency remains outstanding.

  • · McIllree resigned from the Board and all assignments with the Company on October 20, 2026
  • · Nasdaq cure period runs until the earlier of the next annual shareholders' meeting or October 20, 2027; if the annual meeting occurs before April 19, 2027, compliance must be evidenced by April 19, 2027
  • · The audit committee deficiency under Rule 5605(c)(2)(A) was cured on October 27, 2026 via Furlan's appointment

  • · 8-K signed by CEO Robert Price on October 29, 2026
Propanc Biopharma, Inc. 8-K negative materiality 8/10

29-10-2026

Propanc Biopharma received a Nasdaq notice on October 23, 2026 that it is not in compliance with the $1.00 minimum bid price requirement under Listing Rule 5550(a)(2), based on the closing bid price over the 30 consecutive business days prior to October 21, 2026. Because the company had already effected a reverse stock split within the prior one-year period, it is ineligible for the standard 180-calendar day compliance period under Rule 5810(c)(3)(A)(iv), and its securities face delisting on November 2, 2026 unless it appeals by October 30, 2026. The company intends to appeal, believing it has cured the deficiency, though it acknowledges delisting would reduce liquidity, shrink its investor base, limit access to public capital markets, and impair its ability to grant equity incentives.

  • · Delisting would take effect November 2, 2026 absent an appeal
  • · Appeal deadline is October 30, 2026; an appeal stays the delisting pending the Panel's decision
  • · Receipt of the Notice does not affect the company's business, operations, or SEC reporting requirements
  • · Company is incorporated in Delaware, Commission File Number 001-42806, IRS EIN 33-0662986
  • · Principal executive office is at 302, 6 Butler Street, Camberwell, VIC, 3124, Australia
  • · Company is not an emerging growth company

29-10-2026

Glucotrack, Inc. (GCTK) received written notice from a Nasdaq Hearings Panel on October 28, 2026, determining to delist its securities because its closing bid price was $0.87 on October 14, 2026, failing to satisfy the terms of a previously granted exception to the $1.00 minimum bid price requirement under Nasdaq Listing Rule 5550(a)(2). Trading in the common stock will be suspended at the open on October 30, 2026, and Nasdaq is expected to file a Form 25 to delist and deregister the shares under Section 12(b). The company plans to have its shares quoted on the OTC Markets OTCID tier upon suspension, though no assurance of that transition is provided.
