What Is an Equity Line of Credit (ELOC)?

Alphanume Team · May 24, 2026

The standby purchase agreement that lets a company put stock to an investor on demand — and the dilution mechanic that comes with it.

An equity line of credit, or ELOC, is a contractual arrangement that lets a public company sell newly issued shares to a designated investor at any time during the life of the facility, typically subject to volume caps and pricing formulas tied to recent market prices. The structure sits at the intersection of an ATM offering and a PIPE: it's continuous like an ATM, but the buyer is a single committed counterparty rather than the open market.

How an ELOC works

The mechanics:

The company and the investor sign a purchase agreement. The agreement specifies an aggregate dollar commitment (e.g., "up to $50 million"), the term (often 24–36 months), and the per-draw mechanics.
The company files a resale registration. A Form S-1 or S-3 registers the resale of shares the ELOC investor will receive, allowing the investor to immediately turn around and sell into the market.
The company exercises "put rights" against the facility. When the company wants cash, it delivers a put notice to the investor specifying the dollar amount or share count. The investor is contractually obligated to purchase, subject to volume and pricing thresholds.
The investor sells. The investor typically sells the purchased shares into the open market over the following days to monetize the position.

Pricing formulas

The signature feature of an ELOC is the pricing formula — typically a discount to recent VWAP over a defined pricing period. Common variations:

"Purchase price equal to 95% of the average VWAP over the three trading days following delivery of the put notice"
"Purchase price equal to 97% of the volume-weighted average price on the day of the put"
"Purchase price equal to the lower of (i) the closing price on the put date and (ii) 90% of the average VWAP over the five-day pricing period"

The narrower the discount, the more attractive the facility for the issuer. A 3% discount is friendly; a 10% discount is closer to a structured-PIPE-style instrument. Variable discounts that widen during volatile periods are common.

ELOC vs ATM

ELOCs and ATM programs overlap functionally but differ in important ways:

Counterparty. ATM sells to the open market through an agent; ELOC sells to a specific committed investor.
Discount. ATM has no discount (sells at market); ELOC always carries a discount to the pricing formula.
Disclosure. ATM utilization is disclosed in 10-Q/10-K filings; ELOC draws are typically disclosed via 8-K or in the resale prospectus supplement.
Investor flexibility. ATM agents have no commitment to buy; ELOC investors are contractually committed within agreed caps.

For small-cap issuers, the ELOC is often the structure of last resort when traditional ATMs are not available due to market-maker concerns or low average volume.

What ELOCs signal

The presence of an ELOC by itself is neutral — many otherwise-healthy issuers maintain ELOCs as backup capital. What matters is utilization:

Idle ELOCs can sit on the books for years without material draws.
Active ELOCs — particularly accelerating draws — are a strong signal of cash burn outpacing operating cash flow.
Repeated draws at progressively lower prices are a signature of a deteriorating fundamental position.

The disclosure pattern matters: companies that disclose ELOC draws via 8-K signal each event in real time; companies that only disclose utilization in 10-Q footnotes give the market a delayed picture.

Reading the trail in filings

The filing sequence for an ELOC:

8-K announcement. Discloses the purchase agreement and high-level terms; the agreement is filed as an exhibit.
S-1 or S-3 resale registration. Registers the resale of shares to be issued under the facility. Must be declared effective before draws can occur.
Prospectus supplements. Many ELOCs require prospectus supplements as draws occur, identifying the cumulative shares sold and remaining capacity.
Quarterly disclosures. 10-Q and 10-K discuss the program's utilization, average price, and remaining capacity.

Investor-side dynamics

The ELOC investor is structurally short — they buy at a discount and need to sell into the market to monetize. This creates predictable selling pressure on the days following each put notice. Patterns to watch:

Volume spikes one to three trading days after a put-notice 8-K, as the investor distributes.
Hedging activity — including pre-borrow shorting — that depresses the stock during the pricing period.
Concentration of selling around earnings or other events that affect liquidity.

Where Alphanume fits

Alphanume's Dilution Events dataset tracks ELOC announcements, links each to its resale registration, and surfaces draw events through subsequent prospectus supplements and 8-K disclosures. The result is a continuous utilization track per facility rather than a stack of dispersed filings.
