TTM revenue $852M · Q1 +93% YoY
◆ WATCH — PULLBACK TO $150–170
Entry zone: $150–170
Mandatory connective tissue for every Blackwell GPU cluster — PCIe, CXL, and Ethernet connectivity chips that no hyperscaler can skip. Revenue 100% AI infrastructure (not a narrative play). Q1 2026 +93% YoY. As NVIDIA expands from NVLink-only to broader AI fabric interconnects, ALAB becomes the bottleneck supplier. FCF positive, recently IPO'd.

Valuation vs Growth
C+
Fwd P/E 80-82× on 93% revenue growth gives PEG 2.34 — borderline. Average analyst PT $192.15 is now below current price, meaning analysts have caught up to the move. At $195 there is no embedded upside vs consensus. Short interest 8.43% signals informed bears have a view on valuation. Better entry $150-170.
Expensive for new entry at $195. Pullback needed before the risk/reward is favourable.
Fundamentals vs Hype
B+
Revenue 100% AI infrastructure — PCIe/CXL chips are mandatory in every Blackwell cluster. +93% YoY is real and measurable. FCF positive. GF Score 23/100 reflects short public track record (recently IPO'd), not fundamental weakness. As NVIDIA expands AI fabric architectures, ALAB is the non-optional supplier.
Grounded — connective tissue of the Blackwell ecosystem.
Institutional vs Retail
B
IO Fund entered at $118.52 (Feb 2026, +65% gain). Institutional coverage building as company graduates from small-cap. Avg analyst PT at current price — institutions have fully repriced the known upside. 8.43% short interest is elevated and represents informed valuation skepticism.
Balanced — institutions have caught up. Short interest is the watch signal.
Verdict
Watch — wait for pullback to $150-170. The thesis is genuine: every Blackwell rack needs ALAB's connectivity chips, and this is not replicable quickly by competitors. But at $195 the average analyst target has been met, 8.43% short interest signals valuation risk, and PEG 2.34 provides no margin of safety on a slip. IO Fund's 65% gain from $118 gives them margin of safety that new entrants do not have. A 15-22% pullback restores the risk/reward.
Entry zone: $150–170 on pullback (IO Fund cost basis $118.52)
⚠ Key Risks
- 01Short interest 8.43% — elevated for a mid-cap; represents active bet against the valuation by informed participants
- 02Avg analyst PT below current price — no consensus upside; any estimate revision down triggers meaningful selling
- 03Recently IPO'd (GF Score 23/100) — limited operating history through a full cycle; limited institutional track record
- 04Competition from Marvell, Broadcom in PCIe/CXL connectivity — ALAB is not the only supplier
- 05NVDA architecture shift — if Blackwell successor uses a different interconnect standard, ALAB's design win advantage resets
