According to Benzinga Pro movers data, here are the five best-performing small-cap tech stocks so far in June, screened for market caps between $300 million and $10 billion. ## 5\. Ultra Clean Holdings: Up 31.77% **Ultra Clean Holdings Inc**. **(NASDAQ:UCTT)**makes the subsystems that chip-equipment makers build into their tools: gas-delivery systems, wafer-cleaning modules and chemical-delivery hardware. Its revenue tracks how much gear the industry ships. On June 8 management met investors at an Oppenheimer broker event. The firm then raised its price target to $115 from $100 and reiterated an Outperform rating, citing a semiconductor-equipment cycle it now sees running stronger and longer than modeled. The stock has roughly tripled year to date. ## 4\. Veeco Instruments: Up 32.38% **Veeco Instruments Inc**. (NASDAQ:VECO) builds process equipment used to fabricate advanced logic, memory and packaging, including laser-annealing, ion-beam and deposition systems. The gain followed a follow-on order for its Nanosecond Annealing System, the NSA500, from a logic customer that had completed an evaluation. Veeco moved with the broader chip-equipment group, which rallied through early June. ## 3\. Arqit Quantum: +33.25% **Arqit Quantum Inc.** (NASDAQ:ARQQ) is a UK-based company that sells quantum-safe encryption, cryptography designed to withstand future quantum computers capable of breaking current standards. On June 1 a U.S. federal court approved a $7 million settlement resolving all outstanding US securities class actions, removing a multi-year legal overhang. The company had also reported first-half revenue up 829% from a year earlier, off a base of about $623,000. ## 2\. **REalloys**: +51.14% **REalloys Inc.** (NASDAQ:ALOY) is assembling a rare-earth supply chain that bypasses China, running from feedstock to magnet metallization at a facility in Ohio. The company confirmed inclusion in the Russell 3000 Index effective June 29 and drew a Buy initiation from Needham with a $19 price target. A letter of intent with Patriot Exploration & Mining added priority access to a large US magnet-metal resource, following an earlier memorandum with Ramaco Resources and a 15-year offtake tied to Greenland’s Tanbreez project. ## 1\. **Horizon Quantum Holdings**: +85.76% **Horizon Quantum Holdings Ltd.** (NASDAQ:HQ) is a Singapore-based company that develops hardware-agnostic software meant to make quantum programming function like conventional coding. Shares jumped after Horizon agreed to install a 256-qubit trapped-ion system from IonQ at its European headquarters in Dublin, a deployment backed by Ireland’s National Semiconductor Strategy. The stock rose 63% in one session and 114% over five days. Needham initiated coverage on June 3 with a Buy rating and a $20 target. Horizon remains in a pre-revenue phase. *Source: Benzinga Pro* ### Related Stocks - [ARQQW.US](https://longbridge.com/en/quote/ARQQW.US.md) - [UCTT.US](https://longbridge.com/en/quote/UCTT.US.md) - [ALOY.US](https://longbridge.com/en/quote/ALOY.US.md) - [ARQQ.US](https://longbridge.com/en/quote/ARQQ.US.md) - [VECO.US](https://longbridge.com/en/quote/VECO.US.md) - [HQ.US](https://longbridge.com/en/quote/HQ.US.md) - [METC.US](https://longbridge.com/en/quote/METC.US.md) - [IONQ.US](https://longbridge.com/en/quote/IONQ.US.md) - [METCI.US](https://longbridge.com/en/quote/METCI.US.md) - [METCB.US](https://longbridge.com/en/quote/METCB.US.md) - [METCZ.US](https://longbridge.com/en/quote/METCZ.US.md) - [METCL.US](https://longbridge.com/en/quote/METCL.US.md) - [HQWWW.US](https://longbridge.com/en/quote/HQWWW.US.md) - [IONQ+.US](https://longbridge.com/en/quote/IONQ+.US.md) ## Related News & Research - [2 New Under-the-Radar Quantum Stocks Catching Analysts' Attention](https://longbridge.com/en/news/296473235.md) - [Ultra Clean enters ATM equity distribution agreement for up to $400 million common stock sale](https://longbridge.com/en/news/295938113.md) - [1 quantum stock near 52-week lows with Nvidia partnership backing is poised to rebound](https://longbridge.com/en/news/296261508.md) - [Veeco CEO William John Miller disposes of common shares worth $10.79 million](https://longbridge.com/en/news/296401344.md) - [Quanome Technologies Establishes Global Quantum Council and Scientific Advisory Network | QNME Stock News](https://longbridge.com/en/news/296506868.md) --- > **Disclaimer: This article is for reference only and does not constitute any investment advice.**
