The move follows a similar announcement from Boeing (BA.N) last week on its 2024 forecast and comes as the companies face scrutiny from investors, regulators and lawmakers following the mid-air blowout on a 737 MAX 9 aircraft last month.
"The quality and safety of the products we produce is paramount above all," Interim CEO Patrick Shanahan said in a statement.
Spirit made the fuselage for the aircraft in question.
There were no serious injuries, but the accident prompted the U.S. Federal Aviation Administration (FAA) to bar Boeing, Spirit's biggest customer, from lifting production of 737 MAX.
The U.S. National Transportation Safety Board will release its preliminary report on the accident on Tuesday.
For the quarter, Spirit reported a free cash flow of $42 million due to a $100 million funding received from Boeing, but that fell short of analysts' expectation of $122.35 million, as per LSEG data.
The company's shares reversed course to rise 1% in early trade. They have fallen about 16% since the mid-air blowout in early January.
Spirit had said it expects to generate free cash in 2024 following years of cash burn on cost overruns and supply jams.
Under an agreement reached in October to alleviate soaring costs, Boeing agreed to provide Spirit immediate funding and revised prices for 737 and 787 production.
This helped Spirit reverse some forward losses of $34.3 million during the quarter through December but it recorded losses on the Airbus A350 program of $76.0 million and Airbus A220 program of $57.7 million.
Shanahan, a former U.S. deputy secretary of defense, has stressed the need for a Boeing type-agreement with Airbus that relieves those cost pressures, primarily on the single-aisle A220 program. Airbus declined comment on Tuesday.
"The incremental charges on A220 and A350 in 4Q23...highlight the need for such an agreement," J.P. Morgan analyst Seth Seifman wrote in a note.
Wichita, Kansas-based Spirit reported an adjusted profit per share of 48 cents for the quarter, compared with expectations of 87 cents.
Revenue rose 37% to $1.81 billion, beating expectations of $1.74 billion due to higher parts deliveries on both Boeing and Airbus commercial jet programs.
Spirit delivered 104 737 fuselages to Boeing in the quarter, averaging 34.66 per month. The planemaker said last week it was producing 38 737 jets per month.
