Kyndryl's problems are related to IBM's problems, but the central issue both companies face is that both firms are losing relevancy in the modern world. Less relevancy means less customers, less customers means less revenue, blah blah blah. As very close relatives, executives at both firms employ the same book-cooking methods to make the stocks look good and to preserve whatever free cash flow they still have.
They are both doing as best they can under the circumstances, but the trajectories for both companies are still down...albeit for different reasons, due to the markets they allegedly serve.
