This is indeed an involved sentence.
这真是个复杂难懂的句子。
由动词involve演化而来的形容词involved,放在名词前和名词后有不同的含义。放在名词后使用,大多是这个词的本意“牵扯进来的、有关的、卷入的”(Connected by participation or association);放在名词前使用,意思大多是“复杂的、不易懂的、难于解开的”(stresses confusion arising from the commingling of parts and the consequent difficulty of separating them)。

牵扯到的公司中有一家是国企。(involved另一个含义的用法)
