What Grid Dynamics Holdings, Inc. told the SEC could break it.
Grid Dynamics' disclosures pair a concentrated client base with a geographically exposed delivery workforce. Its revenue is top-heavy — one customer was 15.4% of 2025 revenue and its ten largest clients were 57.7% (top 20, 73.4%) — so losing a major client would bite. At the same time, it delivers its engineering services from offices across Ukraine, Serbia, Poland, Armenia, and India, placing a meaningful share of its workforce in the path of the Russia-Ukraine war and related sanctions, and it competes hard for scarce IT talent across those regions, where attrition or wage pressure could squeeze gross margins. Because it earns largely in dollars, pounds, and euros while paying costs in Polish zlotys, rupees, pesos, and other currencies, it also carries multi-currency FX risk.
