February 20, 2024 — 1-for-10 reverse split

• Action: 1-for-10 reverse stock split (every 10 pre-split shares were consolidated into 1 post-split share).
• Effective date / exchange effective: February 20, 2024, per exchange notices. As of Feb 20, 2024, Nasdaq Trader published a corporate-action notice referencing the effect of the reverse split on the company's CUSIP and trading metrics; clearing organizations issued option adjustment notices.
• Immediate technical details:
  • CUSIP and other security identifiers: exchange records noted an administrative CUSIP change consistent with the reverse split; shareholders and brokers received custodial-level updates to reflect the new share identifiers.
  • Options and derivatives: option exchanges and clearing organizations issued contract adjustment memos to change exercise prices and multipliers (e.g., OCC/MIAX notices adjusted contract terms to reflect a 1-for-10 reverse split). Option contract symbols and exercise calculations were adjusted in accordance with standard clearing procedures, with notices published by option exchanges/clearing houses.
  • Outstanding share count: the total recorded shares outstanding was reduced in the 10:1 ratio in consolidated records; exact outstanding counts are reported in post-split filings and exchange notices.

May 11, 2020 — 1-for-12 reverse split

• Not all primary sources treat this item as a formal “stock split” event; some databases include it while others omit it. When you research historical share adjustments, expect minor discrepancies for small fractional or housekeeping corporate adjustments.

Rationale and corporate reasons for reverse splits

Companies undertake reverse stock splits for several common, high-level reasons. Understanding the typical motives helps interpret Aurora’s actions without inferring beyond stated company objectives and regulatory notices.

• Raise the per-share trading price: a reverse split increases the nominal per-share price by consolidating shares, which can make a stock more attractive to some institutional investors or market participants that have minimum price thresholds.
• Meet listing requirements: exchanges often require a minimum bid price or market capitalization; companies with prolonged low per-share prices may consolidate shares to help meet the exchange’s listing standards.
• Simplify capital structure or reduce administrative complexity: corporate restructurings, capital reorganizations or rounding corrections can motivate small forward adjustments or consolidations.

For Aurora specifically, the documented reverse splits in 2020 and 2024 occurred in the context of low per‑share trading prices and corporate restructuring efforts. Public filings and exchange notices referenced the reverse splits as part of capital-structure adjustments; many commentators and corporate-action records associate such steps with efforts to maintain compliance with exchange listing standards and to position the company for more orderly trading.

Mechanics and effects on shareholders

How a reverse split works in practice — and what shareholders can expect — is summarized below.

• Basic math: a 1-for-10 reverse split means every 10 pre-split shares become 1 post-split share. Example: if an investor held 1,000 pre-split shares, after a 1-for-10 reverse split they hold 100 post-split shares.
• Market capitalization: in theory, a reverse split does not change the company's market capitalization immediately because the share count is reduced while the per-share price increases proportionally; however, actual market value can move due to investor reaction, liquidity changes, or perceptions about company fundamentals.
• Fractional shares: when a shareholder’s consolidation would produce a fractional share, standard practice is for the company or transfer agent to pay cash in lieu for fractional entitlements (the cash value is typically calculated using the closing price on the effective date or a designated valuation method). Brokerage platforms sometimes aggregate fractional entitlements or apply their own handling rules; check your broker’s specific policy.
• Broker account effects: brokerages and custodians typically perform the consolidation on behalf of customers and will display updated share totals after the corporate action settles. Some brokerages may show a pre-split position and then a post-split adjustment line; expect to see consolidated quantities within one or a few business days of the effective date.
• Tax considerations: reverse splits are generally not taxable events by themselves in most jurisdictions — they change share counts but not the total economic interest — but shareholders should consult tax guidance relevant to their country.
• Derivative instruments and options: option contracts are adjusted by the options clearing organization (e.g., OCC) or the specific exchange to reflect the new share basis. Adjustments may change the contract multiplier, strike price, and contract symbol. Notices from option exchanges detail the exact adjustments; traders with open positions should review clearing notices for the specific adjustments and exercise/assignment rules.

Regulatory/technical adjustments and record-keeping

Reverse splits trigger several administrative changes. The principal items typically include:

• Security identifiers: the company's CUSIP (or equivalent ISIN) may change; exchanges note the new identifier in their notices so custodians and market-data systems can map records correctly.
• Ticker and symbol adjustments: depending on exchange rules, a company may retain its ticker or temporarily trade under a different identifier for trade reporting while systems update.
• Option contract adjustments: the OCC and option exchanges issue formal memos describing new contract multipliers, adjusted strike prices, and symbol changes. These memos are the authoritative source for how listed options are handled.
• Outstanding shares and filings: the company updates the authorized and outstanding share count in subsequent regulatory filings (e.g., quarterly/annual reports or current reports) showing the post-split totals.
• Source publication: official notices are posted on exchange bulletin systems and clearing-house communications; companies also publish press releases and file amendments or current reports with securities regulators.

When verifying any corporate action, use the primary notices from exchange bulletins and the company’s regulatory filings as the definitive record.

Market reaction and price performance

• Short-term volatility: share consolidations, including reverse splits, are often accompanied by short-term volatility around the effective date. Traders and algorithmic strategies can create higher intraday moves as the market reprices on the new share basis.
• Liquidity considerations: a reverse split reduces the number of shares outstanding and can reduce displayed liquidity per price level if trading interest does not scale proportionally; this can increase bid-ask spreads for a period.
• Longer-term performance: long-term price direction depends on the company's underlying business performance and fundamentals, not the split ratio. Historical analyses show that reverse splits are not reliable predictors of improved long‑term returns; they are primarily corporate-structure tools.

To assess ACB’s post-split performance, review historical price charts spanning the split dates and compare adjusted prices (accounting for the split ratios). Exchange notices and company filings provide the authoritative split ratios to use for chart adjustments.

How to verify and where to find official information

To confirm any corporate-action detail, shareholders should consult primary authoritative sources. Recommended checks:

• Company press releases and investor relations announcements (search the company’s investor relations page and press archive). Look for the exact effective date and the board authorization language.
• Securities filings: for a Canadian issuer, check SEDAR/SEDAR+ filings and U.S. EDGAR (if cross-filed) for current reports or amendments that disclose the split and updated outstanding share counts.
• Exchange notices: Nasdaq Trader or the listing exchange bulletin will publish a corporate-action notice (for example, notices that include the corporate action ID and effective date).
• Options clearing/exchange memos: clearing organizations such as the OCC and options exchanges publish adjustment memos describing how open contracts are handled (these memos contain the official contract-adjustment details).
• Broker statements and custodial confirmations: your brokerage/custodian will provide transaction-level detail showing the split adjustment and any cash-in-lieu payments for fractional shares.

As of Feb 20, 2024, exchange and clearing notices publicly documented the 1-for-10 reverse split; as of May 11, 2020, company disclosures and exchange records documented the 1-for-12 reverse split.

Frequently asked questions (brief)

• Does a reverse split change my investment value?

  • No — a reverse split consolidates shares and increases per-share price proportionally so that the investor’s total market value, in theory, remains the same immediately after the split (excluding market movement and transaction effects).

• What happens to fractional shares?

  • Fractional shares resulting from a reverse split are typically converted to a cash payment (cash in lieu) determined by the company’s transfer agent or brokerage, or they may be rounded per the broker’s policy.

• Will my option contracts change?

  • Yes — option contracts are adjusted by the options clearing organization and exchanges; strike prices, multipliers and contract symbols may be changed to reflect the consolidation.

• Where is the official documentation?

  • Official documentation appears in company filings (SEDAR/EDGAR), exchange notices and clearing organization memos; shareholders should consult those primary sources for verification.

Note: Do not rely solely on aggregator databases for precise legal or accounting treatment. Prioritize the company’s filings and exchange/clearing notices as the authoritative record.

Notes on source discrepancies

Split-history aggregators and commercial market-data vendors sometimes differ in how they record minor housekeeping adjustments (for example, small forward adjustments, rounding corrections, or share-class transfers). The 2018 1037:1000 forward adjustment is one such item where some databases include the entry and others omit it. When you encounter discrepancies:

• Prioritize primary filings and exchange notices (company press releases, SEDAR/EDGAR filings, Nasdaq Trader bulletins, and OCC memos).
• Use aggregator data for quick reference but validate unusual entries against the primary sources.

Practical next steps for shareholders

• Check your broker or custodian account statements for a post-split share total and any cash-in-lieu entries for fractional shares.
• Review the company’s regulatory filings and the exchange/clearing notices for exact dates and official language relating to the split.
• If you hold options or other derivatives, consult the exchange/clearing memos that were published around the effective date for the precise contract adjustments.
• For custody, trading and wallet needs, consider using Bitget’s suite of services (exchange accounts for trading and Bitget Wallet for custody) to ensure you receive clear post-event statements and support for corporate-action processing.

More about verification and data validation (technical checklist)

• Confirm the effective date and ratio in the company’s investor relations press release or the current report filed with regulators.
• Locate the exchange corporate-action bulletin matching the effective date (look for the corporate-action ID and security identifier updates).
• For options, obtain the OCC/exchange adjustment memo showing the adjusted contract terms and any revised contract symbols.
• Compare pre- and post-split outstanding share counts in the company’s filings to verify the reduction in issued shares.
