SEC Filings & Regulatory Compliance
8-K Current Report
A current report filed with the SEC to disclose material corporate events that shareholders should know about promptly — such as earnings releases, executive changes, acquisitions, or entry into significant agreements. Public companies must file an 8-K within four business days of a triggering event. For micro-caps, consistent 8-K cadence is a critical signal of operational activity to institutional screening algorithms.
Full definition + why it matters →10-K Annual Report
The comprehensive annual report every U.S. public company must file with the SEC within 60–90 days of its fiscal year-end (depending on filer status). It includes audited financial statements, MD&A, risk factors, and disclosures about business operations and controls. The 10-K is often the most-read document by institutional analysts and their automated screening tools — its structure and language quality directly affect algorithmic visibility.
10-Q Quarterly Report
A quarterly report filed with the SEC for each of the first three fiscal quarters, containing unaudited financial statements and management discussion. Large accelerated filers must file within 40 days; smaller reporting companies have 45 days. Missing a 10-Q deadline or filing a late form (NT 10-Q) is an early warning signal to compliance monitors and can trigger Nasdaq notifications.
S-1 IPO Registration
The initial registration statement a company files with the SEC before conducting an initial public offering (IPO). The S-1 discloses the company's business, financials, risk factors, use of proceeds, and offering terms. It undergoes SEC review and comment before the company is permitted to sell shares to the public. For SPACs, the S-1 covers the blank-check offering; the target company's business is disclosed in a later proxy or S-4.
S-3 / Shelf Registration Shelf Offering
A registration statement that allows eligible public companies to register securities for sale on a delayed or continuous basis — effectively putting securities "on the shelf" for issuance when market conditions are favorable. To qualify, companies generally need at least $75M in public float or must meet other eligibility criteria. An effective S-3 is a prerequisite for at-the-market (ATM) offering programs.

The definitive proxy statement companies file with the SEC and distribute to shareholders before annual (or special) meetings, soliciting votes on director elections, executive compensation, auditor ratification, and other matters. Institutional investors and proxy advisory firms (ISS, Glass Lewis) scrutinize proxy filings for governance quality. Filing a timely, well-structured proxy is a positive compliance signal.
Full definition →NT 10-K (Late Filing) Compliance Risk
A notification filed with the SEC when a company cannot meet its 10-K deadline, granting a 15-calendar-day extension. While NT filings are permitted, repeated or unexplained late filings raise red flags with institutional screeners and compliance monitors. Nasdaq may issue a deficiency notice if filings are not completed within the extension period.
Form 4 Insider Transactions
A form filed by company insiders (directors, officers, and 10%+ shareholders) within two business days of any change in their beneficial ownership of company securities. Form 4 transactions are tracked by institutional investors, short sellers, and algorithms as signals of insider sentiment. A pattern of insider buying can be a positive signal; unexpected selling may raise questions.
SC 13D / 13G Beneficial Ownership
SEC filings required when an investor acquires 5% or more of a company's outstanding shares. Schedule 13G (the shorter form) is for passive investors with no intent to influence control; Schedule 13D is for activist investors who may seek to influence management or strategy. A new 13D filing is often a market-moving event, signaling that an activist may be accumulating.
Reg FD — Regulation Fair Disclosure Disclosure Rule
An SEC rule requiring that when a public company discloses material nonpublic information to certain securities market professionals or shareholders, it must simultaneously (or promptly) make that information available to the general public. Reg FD prevents selective disclosure — the practice of tipping favored investors before a public announcement. Violations can result in SEC enforcement action.
Full definition + compliance checklist →Regulation S-K Disclosure Standards
The SEC's integrated disclosure regulation that specifies what must be included in the non-financial portions of registration statements and periodic reports (10-K, 10-Q, proxy). It governs content requirements for MD&A, risk factors, executive compensation, and more. Understanding S-K requirements is essential for structuring filings that satisfy both SEC reviewers and institutional algorithms.
SEC Comment Letter SEC Review
A letter from the SEC's Division of Corporation Finance staff identifying issues, questions, or requested clarifications in a company's filings. Comment letters and the company's responses are made public on EDGAR after a review is complete. Receiving a comment letter on a sensitive topic (revenue recognition, going concern, related-party transactions) can attract short-seller attention and analyst scrutiny.
EDGAR Filing Platform
The SEC's Electronic Data Gathering, Analysis, and Retrieval system — the public database where all company filings are submitted and stored. EDGAR is accessible free to the public at sec.gov. Institutional algorithms, short sellers, and news services all monitor EDGAR feeds in real time. Filing on EDGAR triggers immediate algorithmic processing by data vendors including Bloomberg, Refinitiv, and S&P Global.
PCAOB Audit Standards
The Public Company Accounting Oversight Board — the nonprofit organization established by the Sarbanes-Oxley Act to oversee audits of public companies. PCAOB-registered auditors must follow PCAOB auditing standards, and the board inspects registered firms periodically. Smaller public companies must use PCAOB-registered auditors; micro-caps switching to larger PCAOB-registered firms often see it interpreted as a governance upgrade signal.
Transfer Agent Share Administration
A financial institution or third-party service provider that maintains the official records of a company's shareholders, processes share transfers, issues certificates, and manages distributions. Transfer agents also provide the round-lot holder counts that Nasdaq uses to assess listing compliance. For micro-caps, choosing a reputable transfer agent with real-time reporting capabilities can simplify compliance monitoring.
Capital Markets & Investor Types
IR — Investor Relations Function
The strategic communication function that manages the relationship between a public company and its investors, analysts, and the broader financial community. IR encompasses earnings calls, investor presentations, press releases, SEC filings, analyst outreach, and conferences. Effective IR for micro-caps requires simultaneously satisfying SEC disclosure obligations, Nasdaq listing standards, and the informational needs of institutional algorithms.
Institutional Investor Investor Type
An organization that pools capital and invests on behalf of clients or beneficiaries — including mutual funds, pension funds, hedge funds, insurance companies, endowments, and registered investment advisers. Institutional investors control the majority of public market volume, and their algorithmic screening systems largely determine which small-cap and micro-cap stocks receive professional attention. Being "institutionally visible" is a prerequisite for sustainable liquidity.
13F — Institutional Holdings Report Ownership Data
A quarterly filing required from institutional investment managers with at least $100 million in qualifying assets under management, disclosing their equity holdings as of each quarter-end. Published 45 days after quarter-end, 13F filings are a lagging but widely-used indicator of institutional interest in a stock. Appearing in new 13F filings is a meaningful signal of growing institutional recognition.
Full definition →Float Market Structure
The portion of a company's outstanding shares that are available for trading by the general public, excluding shares held by insiders, restricted shareholders, and controlling holders. Float is a critical input in Nasdaq listing standards, institutional screening, and trading liquidity assessments. Low-float stocks are more susceptible to price volatility and short squeezes; very low float can trigger Nasdaq deficiency notices.
Round-Lot Holder Nasdaq Compliance
A shareholder who owns at least 100 shares of a company's stock. Nasdaq listing rules require companies to maintain a minimum number of round-lot holders (typically 400 for the Nasdaq Capital Market) as evidence of broad shareholder distribution. A declining round-lot holder count — often caused by high SPAC redemptions or reverse stock splits — can trigger a Nasdaq deficiency notice.
See also: Nasdaq Rule 5810 →Market Cap — Micro / Nano / Small-Cap Size Category
Market capitalization is total shares outstanding multiplied by the current share price. Size categories: nano-cap (below $50M), micro-cap ($50M–$300M), small-cap ($300M–$2B). AxonIR is purpose-built for companies in the sub-$1B range where institutional coverage is sparse and algorithmic visibility is hardest to achieve. Size tier affects Nasdaq reporting deadlines, index eligibility, and which institutional funds are permitted to hold the stock.
Liquidity Trading
The ease with which a security can be bought or sold without significantly moving its price. For micro-caps, liquidity is usually measured by average daily trading volume, bid-ask spread, and market depth. Poor liquidity discourages institutional participation (large orders move the price adversely) and is often a self-reinforcing problem — thin volume causes wide spreads, which deter more volume. Improving IR quality is one pathway to organically improving liquidity.
PIPE — Private Investment in Public Equity Financing
A capital-raising transaction where accredited investors (typically institutional) purchase securities directly from a public company at a negotiated price, bypassing the public markets. PIPE transactions are common among micro-caps and de-SPAC companies that need quick capital but cannot easily access it through traditional public offerings. PIPEs typically require SEC registration rights and can create dilution overhang if not managed carefully.
ATM Offering — At-the-Market Capital Markets
An at-the-market equity offering program under which a company sells newly issued shares directly into the open market through a designated broker-dealer, at prevailing market prices, on an opportunistic basis. ATM programs require an effective S-3 shelf registration and allow companies to raise capital without the discount, fees, or dilution overhang of traditional secondary offerings. ATM activity appears on market surveillance systems and can suppress short-term price if not communicated clearly.
Full definition →Reverse Stock Split Capital Structure
A corporate action that reduces the number of outstanding shares by a set ratio (e.g., 1-for-10) while proportionally increasing the per-share price — the total market cap is unchanged. Public companies most commonly use reverse splits to regain compliance with Nasdaq's $1.00 minimum bid price requirement. While technically neutral, the market often interprets reverse splits as a sign of financial stress; studies show negative post-split price performance on average.
Trading, Market Signals & Compliance
Volume Ratio Signal
The ratio of a stock's current-period trading volume to its historical average (typically 20-day or 90-day). A volume ratio significantly above 1.0 — sometimes called a "volume spike" — indicates unusual interest in the stock, whether from institutional accumulation, news coverage, short-selling activity, or algorithmic triggers. AxonIR Signals tracks volume ratios across its coverage universe to identify when a company's filing events correlate with measurable institutional attention.
Short Interest Market Signal
The total number of shares of a company that have been sold short but not yet covered or closed out, typically expressed as a percentage of float. High short interest (above 20–30% of float) indicates significant bearish positioning and can create conditions for a short squeeze if positive news drives buyers into a thin market. Short interest data is published semi-monthly by exchanges and tracked by institutional data services.
Short Seller Market Participant
An investor who borrows shares to sell them, betting the price will fall so they can repurchase at a lower price and return the borrowed shares at a profit. Activist short sellers (like Hindenburg Research or Muddy Waters) publish research reports critical of public companies; these reports can cause immediate, severe price declines. Micro-caps with thin float, governance concerns, or opaque disclosures are disproportionately targeted.
Full definition + defense strategies →Naked Shorting Market Mechanics
The practice of short-selling shares without first locating or borrowing the actual shares — resulting in a "failure to deliver" when the settlement date arrives. Naked short selling is illegal in the United States except in limited market-maker exceptions. Companies sometimes attribute sustained price pressure to naked shorting; while it does occur, SEC enforcement data suggests it is less prevalent than often claimed by management. Investors should evaluate such claims critically.
Nasdaq Rule 5810 — Deficiency Notice Listing Risk
The Nasdaq rule that governs the formal notification process when a listed company falls out of compliance with Nasdaq's listing standards. When Nasdaq determines a company has failed to meet a requirement (minimum bid price, stockholders' equity, round-lot holders, etc.), it issues a deficiency notice under Rule 5810. The notice starts a formal compliance period and remedy timeline. Failure to regain compliance can ultimately result in delisting proceedings.
Full definition + compliance timeline →Minimum Bid Price Nasdaq Standard
Nasdaq listing rules (Rule 5550(a)(2) for Capital Market) require that listed securities maintain a closing bid price of at least $1.00. If a stock closes below $1.00 for 30 consecutive business days, Nasdaq issues a deficiency notice providing a 180-calendar-day cure period. If the bid price does not reach $1.00 for at least 10 consecutive business days during that window, the company may seek a second 180-day period or risk delisting proceedings.
Going Concern Audit Risk
An accounting and auditing term referring to the assumption that a company will continue operating for the foreseeable future (typically 12 months). When an auditor has "substantial doubt" about this assumption — due to recurring losses, negative cash flows, debt covenant violations, or imminent liquidity crises — they issue a going concern opinion in the audit report. A going concern opinion is a serious negative signal that triggers Nasdaq review, institutional selling, and heightened short-seller scrutiny.
Full definition + what to do →Corporate Governance & Investor Communications
Analyst Coverage Equity Research
The publishing of equity research reports and earnings estimates on a company by professional securities analysts. Coverage dramatically expands a company's institutional visibility — analysts' target prices, ratings, and models drive institutional fund flows. Most micro-caps have zero or one analyst; obtaining initial coverage from a boutique or regional bank is often a significant catalysts event. AxonIR's partner network includes coverage facilitation for qualifying companies.
Sell-Side vs. Buy-Side Market Participants
Sell-side refers to investment banks, brokerages, and research firms that produce and distribute research (selling ideas to clients). Buy-side refers to institutional investors — mutual funds, hedge funds, pension funds — who use that research to make investment decisions. Sell-side analysts publish reports with ratings (Buy/Hold/Sell); buy-side analysts do proprietary research for their own funds. For IR strategy, understanding who your potential investors are (buy-side) and who might cover you (sell-side) is essential.
Earnings Call IR Event
A live conference call (often webcast) where company management discusses quarterly or annual financial results with analysts and investors, typically following an earnings press release filed as an 8-K. Earnings calls are high-attention events — algorithms, financial newswires, and live-transcript services process them in near-real-time. Language quality, forward guidance, and Q&A responses all affect how institutional screeners update their models on the company.
Safe Harbor / Forward-Looking Statements Legal
The "safe harbor" provision of the Private Securities Litigation Reform Act of 1995 protects companies from securities fraud liability for forward-looking statements — projections, plans, and expectations about future performance — provided the statements are accompanied by meaningful cautionary language identifying risks that could cause actual results to differ materially. A proper safe harbor disclaimer is standard in all earnings releases, investor presentations, and IR communications.
Full definition + template language →MNPI — Material Nonpublic Information Securities Law
Material nonpublic information is information about a public company that is both material (a reasonable investor would consider it important to an investment decision) and nonpublic (not yet disclosed to the market). Trading on MNPI constitutes insider trading and is illegal. IR professionals must maintain strict information barriers, especially before earnings releases, M&A announcements, and major contract disclosures.
Selective Disclosure Legal Risk
The practice of sharing material information with select investors, analysts, or journalists before making it publicly available. Selective disclosure of material information is prohibited by Reg FD. Common violations occur in one-on-one investor meetings, industry conferences where prepared remarks exceed previously public disclosures, and informal conversations between management and favored analysts.
See also: Reg FD →Lock-Up Period Capital Structure
A contractual period following an IPO or other liquidity event during which insiders, early investors, and SPAC sponsors are restricted from selling their shares. Typical IPO lock-ups last 180 days; SPAC sponsor lock-ups may vary. Lock-up expirations are closely watched — they represent a potential supply surge as restricted holders gain the ability to sell. IR teams often proactively communicate lock-up schedules and sponsor intentions to manage market expectations.
SPAC & De-SPAC Transactions
De-SPAC Transaction
The process by which a Special Purpose Acquisition Company (SPAC) completes a business combination with a private operating company, taking it public. The resulting entity replaces the SPAC's ticker and management. De-SPAC companies face unique IR challenges: algorithmic reset, warrant overhang, low float from redemptions, and the departure of SPAC sponsor attention — all requiring an active 180-day IR rebuild.
Full definition + 180-day IR playbook →SPAC Sponsor SPAC Structure
The private entity (typically a PE firm, investment bank affiliate, or experienced operator) that forms a SPAC, contributes working capital, and receives founder shares ("promote") — typically 20% of post-IPO shares — in exchange for identifying and executing a business combination. Sponsors have strong financial incentives to close a deal; post-close, sponsor lock-up expirations and promote share sales are closely watched by the market as a negative supply signal.
Redemption SPAC Mechanics
In a SPAC structure, public shareholders have the right to redeem (sell back) their shares for their proportional share of the trust account (approximately $10 per share) before the de-SPAC vote, regardless of how they vote on the deal. High redemption rates — sometimes 90%+ — dramatically reduce the float and operating capital of the combined company post-close. Managing and communicating around redemption risk is a core de-SPAC IR challenge.
Warrant Overhang SPAC Risk
The dilution risk created by outstanding SPAC warrants — instruments that allow holders to purchase shares at a fixed price (typically $11.50) after certain conditions are met. If the stock trades near or below the warrant exercise price, warrants create a ceiling on upside and suppress institutional accumulation. Warrant overhang is one of the primary reasons de-SPAC companies trade at persistent discounts to peers that went public via traditional IPO.

Algo-Readability AxonIR Concept
The degree to which a company's public filings and disclosures are structured, formatted, and written in a way that institutional screening algorithms can parse, classify, and act on. Modern institutional investment workflows rely heavily on natural language processing and machine-readable data; poorly structured filings are downweighted or ignored by these systems. Algo-readability encompasses sentence clarity, use of structured data, tagging quality (XBRL/iXBRL), forward-looking statement consistency, and disclosure completeness.
Full definition + how to improve →AxonIR Score Proprietary Score
AxonIR's proprietary 0–100 composite score measuring how algorithmically readable and institutionally visible a public company's IR program is. The score incorporates filing cadence, language clarity, structured data quality, compliance health, disclosure completeness, and momentum. An AxonIR Score above 70 indicates a level of IR quality that institutional screening algorithms are likely to flag positively; below 40 suggests significant structural barriers to institutional attention. The AxonIR Score is an informational metric intended to help IR teams benchmark and improve — it is not investment advice and does not predict stock performance.
