What it means
ときている presents a striking fact as an additional point that makes a situation especially impressive, convenient, difficult, ironic, or otherwise notable. It often follows one or more already-mentioned facts and conveys a sense of “on top of that,” “to make matters more striking,” or “given that.” The speaker is evaluating the situation rather than stating a neutral cause, so it is not a simple substitute for から or ので. It can follow a plain verb or adjective form, as well as a noun or na-adjective used predicatively.
Usage note
ときている is commonly used in explanatory or evaluative statements and can sound emphatic or somewhat conversational. Its polite counterpart ときています changes the sentence-ending politeness but does not remove the construction’s characteristic sense of an additional, noteworthy point.
