Nydar's dilution tracker monitors share issuances, shelf offerings, and ATM programs that affect shareholder value
Nydar's Share Dilution widget surfaces recent dilution events across the market and for individual tickers. Nydar tracks 5 dilution types — ATM offerings, secondary offerings, convertible note conversions, stock-based compensation, and reverse splits — with 6 data points per event including offering amount, new shares added, total shares outstanding, and dilution percentage. Nydar flags events with 10%+ dilution using a red warning badge.
Dilution is one of the most overlooked risks in equity investing. A stock can have strong revenue growth and still destroy shareholder value if it funds that growth by constantly issuing new shares. Nydar's dilution widget puts this data front and centre so you can factor it into every position.
Share dilution happens when a company increases its total shares outstanding. Every new share created reduces the percentage ownership of existing shareholders. If a company had 100 million shares and issues 20 million more, every existing shareholder now owns 17% less of the company — even though they haven't sold a single share.
The impact goes beyond ownership percentage. Earnings per share (EPS) drops, book value per share drops, and if the new shares are sold at below-market prices (common in secondary offerings), the stock price itself takes a direct hit. Repeated dilution is a hallmark of companies that cannot generate enough cash from operations to fund themselves.

Nydar's dilution widget has two viewing modes, toggled by the tabs at the top:
Recent Dilutions
Nydar shows the latest dilution events across all stocks. Use this to scan the market for new offerings and dilution announcements you might have missed.
Ticker View
When you have a stock selected on Nydar's dashboard, this tab appears showing dilution history for that specific ticker. Essential for due diligence before entering a position.
Each entry in Nydar shows the ticker, dilution type badge, offering amount in dollars, number of new shares added, current total shares outstanding, dilution percentage, and the announcement date. Nydar flags events with 10%+ dilution with a red warning badge.
The company sells new shares directly into the open market at current prices. ATM programmes run silently over weeks or months, making them the most insidious form of dilution. Price suppression is gradual and easy to miss.
A large block of new shares is offered at a fixed price, usually at a discount to market. The announcement typically causes an immediate price drop. Watch for underwriter lockup expiry dates after secondaries.
Debt instruments that can be converted into equity at a predetermined price. When the stock price rises above the conversion price, bondholders convert and new shares flood the market. Creates a price ceiling effect.
Shares granted to employees and executives as part of compensation packages. Often overlooked because it is a non-cash expense, but it dilutes ownership just as much as any offering. Tech companies are particularly heavy SBC issuers.
Reduces share count by combining existing shares (e.g. 10:1 turns 100 shares into 10). While not dilution in the traditional sense, reverse splits are often a red flag — companies do them to avoid delisting when the share price drops too low.
Screen for serial diluters
Before entering any position, switch to Nydar's ticker view and check the dilution history. Multiple dilution events in the past year is a major red flag, especially for small-cap stocks. Nydar's dilution history makes serial diluters easy to spot — if a company keeps issuing shares, your position will keep losing value regardless of revenue growth.
Watch for ATM programme announcements
When Nydar flags an ATM programme announcement, shares will be sold gradually over the coming weeks. This creates persistent downward pressure. Consider waiting for the programme to complete before buying, or avoid the stock entirely during active ATM periods.
Size dilution against market cap
A $50M offering on a $10B company is noise. The same offering on a $200M company is devastating. Use Nydar's data to compare the offering amount and share count against the company's total market capitalisation and existing shares outstanding. Cross-reference with Nydar's Stock Info widget for current market cap figures.
Monitor convertible note overhangs
Nydar's convertible note tracking reveals large balances that act as a ceiling on stock price. As the stock approaches the conversion price, note holders convert to equity and sell, capping upside. Factor outstanding convertibles into your price targets using Nydar's dilution percentage data.
Not all dilution is bad. Growth-stage companies sometimes need to raise capital through share issuance. If the raised funds are invested in projects that generate returns exceeding the dilution cost, shareholders ultimately benefit. Evaluate the purpose of the offering, not just its existence.
ATM offerings are underreported. Companies are only required to disclose the existence of an ATM programme, not each individual sale. You may not know the full extent of ATM dilution until quarterly filings are released. Nydar's shares outstanding figure can lag reality.
SBC dilution compounds quietly. Stock-based compensation creates new shares every quarter as options vest and RSUs convert. It does not appear as a dramatic single event, but over years the cumulative dilution can be substantial — some tech companies dilute 3-5% annually through SBC alone.
SEC Filings
Nydar ingests prospectus supplements, S-3 registrations, and 10-Q/10-K share count disclosures.
Corporate Announcements
Nydar processes press releases for offerings, ATM programmes, and convertible note issuances.
