Technical debt has moved from a back‑office IT issue to a board‑level business problem, as legacy systems now drive customer churn, block AI programs, and consume a growing share of tech budgets. This report shows ITAD providers how to turn that pressure into revenue by positioning decommissioning as a modernization enabler rather than an end‑of‑life afterthought, mapping sector‑specific refresh waves in banking, telecom, retail, logistics, and more into concrete decommissioning pipelines. It also includes an executive snapshot quantifying the client upside (run‑rate savings, outage reduction, AI acceleration, ESG gains) and a detailed go‑to‑market guide that helps ITADs frame technical debt in business terms, win a seat at the refresh table, and productize offers like technical‑debt assessments, modernization‑linked playbooks, and AI‑readiness exit plans.
