Osborne Clarke advises Eque2 on acquisition of Chalkstring
Published on 7th July 2026
International legal practice Osborne Clarke has advised Eque2, a leading provider of construction-specific ERP, commercial management and estimating software, on its bolt-on acquisition of Chalkstring, a fast-growing, cloud-based estimating and cost management platform. Eque2 is backed by mid-market private equity firm Bowmark Capital, with the transaction representing a key step in its buy-and-build growth strategy.
Osborne Clarke advised Eque2 across the full transaction lifecycle – from due diligence through to negotiation of the acquisition documentation and execution– drawing on its deep experience in private equity-backed software deals..
The acquisition will be central to Eque2’s next-generation cloud estimating platform, enhancing its ability to support contractors in managing cost, risk and margin from the earliest stages of construction projects. Chalkstring’s cloud-native technology will be developed and scaled as a core part of Eque2’s future estimating offering, while Eque2 continues to support its established Evaluate solution.
This transaction underlines Osborne Clarke’s ability to support private equity-backed platforms on strategic acquisitions in high-growth software markets. Eque2’s acquisition of Chalkstring sits at the intersection of construction, cloud technology and data-led commercial management – areas where our sector focus means we can deliver pragmatic, commercially-focused advice on buy-and-build strategies and wider strategic M&A aligned with our clients’ growth ambitions.
The Osborne Clarke team was led by partner William Nicolson and associate Benjamin Smith (Corporate), supported by partner Michael Carter and associate director Natalie Paddock (Incentives), and partner Lara Fatemi and senior associate Maeve Gillespie (Employment).
