5 Small-Cap Uranium Stocks April 2026 — Scored by Fundamentals
5 small-cap uranium stocks scored on cash runway, debt, and revenue growth. April 2026 data for the SMR nuclear cycle. Updated monthly.
Uranium is mid-cycle. Spot prices have stabilized in the $70-85/lb range after the 2023-2024 spike, SMR (small modular reactor) announcements are accelerating, and utility long-term contracts are being renegotiated at decade-high prices. Supply remains constrained — Kazakhstan's dominance is under scrutiny, and Western production is slowly restarting.
For small-cap uranium investors, the story is simple: if the thesis plays out, leverage is enormous. If it doesn't, most juniors go to zero. The score helps separate "has a chance" from "needs a miracle."
We scored every small-cap uranium stock in our database. Here are the top 5 by total score for April 2026.
Why Uranium Small-Caps Are Brutal to Score
Most small-cap uranium companies are pre-revenue — they own exploration licenses or early-stage development projects. Revenue growth means nothing when you're not selling anything yet. Margins are meaningless. What matters for pre-production uranium juniors:
- Cash runway — can they survive to first production?
- Debt/equity — did they over-lever on exploration?
- Dilution — how many times will they tap shareholders before revenue hits?
- Insider ownership — does management have skin in the game?
That's why most scores in this sector are in the 30-60 range, not the 70-90 range you see in profitable tech.
Top 5 Small-Cap Uranium Stocks by Fundamental Score — April 2026
1. enCore Energy Corp. (EU) — Score: 55.8 | Grade: SPECULATIVE
| Metric | Value | Score |
|---|---|---|
| Revenue Growth YoY | +163.4% | 100 |
| Gross Margin | -12.4% | 0 |
| Cash Runway | 10.5 months | 33 |
| Debt/Equity | 7.15 | 94 |
| P/S Ratio | 8.4x | 53 |
| Rule of 40 | 39.6 | 79 |
| Insider Ownership | 2.3% | 18 |
| 12m Dilution | 0.6% | 96 |
What drives the score: enCore is one of the few small-cap uranium names actually producing — they restarted the Rosita and Alta Mesa in-situ recovery plants in Texas. Revenue is up 163% YoY as production ramps.
Red flags: Negative gross margin (-12%) — they're producing at a loss until plants reach scale. 10-month cash runway means dilution or financing needed this year. Low insider ownership.
Market cap: $0.37B
2. Ur Energy Inc (URG) — Score: 49.6 | Grade: SPECULATIVE
| Metric | Value | Score |
|---|---|---|
| Revenue Growth YoY | +90.7% | 96 |
| Gross Margin | -26.6% | 0 |
| Cash Runway | 12.7 months | 43 |
| Debt/Equity | 0.93 | 99 |
| P/S Ratio | 14.9x | 28 |
| Rule of 40 | -96.5 | 0 |
| Insider Ownership | 7.1% | 51 |
| 12m Dilution | 3.3% | 80 |
What drives the score: Lost Creek ISR project in Wyoming is ramping. Clean balance sheet (D/E 0.93), low dilution history, steady operator.
Red flags: Gross margin deep negative (-27%) — same ramp-up story as enCore but worse margins. Negative Rule of 40 reflects the operating loss.
Market cap: $0.59B
3. IsoEnergy Ltd. (ISOU) — Score: 45.1 | Grade: SPECULATIVE
| Metric | Value | Score |
|---|---|---|
| Revenue Growth YoY | N/A (pre-revenue) | 0 |
| Gross Margin | N/A | 0 |
| Cash Runway | 58.9 months | 100 |
| Debt/Equity | 1.46 | 99 |
| P/S Ratio | N/A | 50 |
| Rule of 40 | N/A | 0 |
| Insider Ownership | 35.1% | 100 |
| 12m Dilution | 26.0% | 4 |
What drives the score: Pure exploration play on the Larocque East uranium discovery in the Athabasca Basin. Nearly 5 years of cash runway (rare for this space) and 35% insider ownership (extremely high — management is aligned).
Red flags: No revenue, heavy dilution (26% in 12 months) funding exploration. If the Larocque discovery doesn't convert to a real mine, the story unravels.
Market cap: $0.67B
4. Uranium Royalty Corp. (UROY) — Score: 32.1 | Grade: HIGH RISK
| Metric | Value | Score |
|---|---|---|
| Revenue Growth YoY | -63.5% | 0 |
| Gross Margin | 22.7% | 30 |
| Cash Runway | 7.2 months | 16 |
| Debt/Equity | 0.07 | 99 |
| P/S Ratio | 13.9x | 31 |
| Rule of 40 | -94.3 | 0 |
| Insider Ownership | 14.4% | 74 |
| 12m Dilution | 3.6% | 79 |
What drives the score: Royalty model on future uranium production plus physical uranium holdings. Clean balance sheet (D/E 0.07) and reasonable insider ownership.
Red flags: Revenue DOWN 64% YoY — timing of royalty payments is lumpy, but that's a big swing. 7 months cash runway is tight. Score reflects the weak trailing 12 months.
Market cap: $0.53B
5. Eagle Nuclear Energy Corp. (NUCL) — Score: 29.4 | Grade: HIGH RISK
| Metric | Value | Score |
|---|---|---|
| Revenue Growth YoY | N/A | 0 |
| Gross Margin | N/A | 0 |
| Cash Runway | 3.0 months | 5 |
| Debt/Equity | 4.44 | 96 |
| P/S Ratio | N/A | 50 |
| Rule of 40 | N/A | 0 |
| Insider Ownership | 21.9% | 88 |
| 12m Dilution | 0.0% | 100 |
What drives the score: Micro-cap ($0.18B) exploration play. 22% insider ownership and zero dilution in last 12 months are positive signals.
Red flags: 3 months cash runway. This company needs to raise capital imminently or find a strategic partner. Not for the faint of heart.
Market cap: $0.18B

What This List Tells You About Small-Cap Uranium Right Now
1. Nobody is profitable yet. Even the "top" scored names (EU, URG) have negative gross margins because they're ramping production. The uranium thesis is intact, but small-cap operators are still in ramp-up.
2. Cash runway is the #1 differentiator. The difference between "scored 45" (IsoEnergy) and "scored 29" (Eagle Nuclear) is mostly runway. Who can afford to wait for the thesis to play out?
3. Insider ownership separates conviction bets from hope. IsoEnergy (35%) and Eagle Nuclear (22%) have meaningful insider stakes. enCore (2%) and Ur Energy (7%) are more institutional-owned. Pick your side.
Risks Worth Knowing
Uranium prices are cyclical. A return to $40/lb (we saw $20/lb in 2020) would wipe out the thesis for most names on this list. Pre-revenue juniors depend on continuing capital market access — if sentiment shifts, dilution accelerates.
Nuclear policy is political. SMR momentum depends on government support and utility procurement. Both can change.
