An M&A studio for the deal you cannot lose. Our reports have been submitted to SGX, HKSE and the Supreme Court of Singapore.
VALLARIS™ independently advises owners, founders and buyers, in Singapore and across borders, who want the best price and terms on a deal or dispute worth USD 10M or more, without overpaying or surprises after signing. We sign what software cannot: the valuation, the diligence and the advice behind the move.
I'm Siong Yoong. My name goes on the number.
I have worked in M&A since 2007, across engagements with aggregate transaction value exceeding USD 2.5B (as of 2026).
What I have seen across those deals is that the outcome is set long before the signing: by the price you anchor, the diligence you trust and the integration you plan. Those are the three places value leaves a deal, and they are where I work.
My valuations and reports have gone before the Singapore Exchange, the Hong Kong Stock Exchange and the Supreme Court of Singapore. The Hong Kong Stock Exchange accepted my fairness opinion for a listing that raised HKD 46.5M.
VALLARIS™ exists so the owner across the table from a well-advised buyer has an adviser of the same standing, who signs for the work.
