This communication includes “forward-looking statements”
within the meaning of the “safe harbor” provisions of the Private Securities Litigation Reform Act of 1995. Longview’s
and HeartFlow’s actual results may differ from their expectations, estimates and projections and consequently, you should not rely
on these forward looking statements as predictions of future events. Words such as “expect,” “estimate,” “project,”
“budget,” “forecast,” “anticipate,” “intend,” “plan,” “may,” “will,”
“could,” “should,” “believes,” “predicts,” “potential,” “continue,”
and similar expressions (or the negative versions of such words or expressions) are intended to identify such forward-looking statements.
These forward-looking statements include, without limitation, Longview’s and HeartFlow’s expectations with respect to future
performance and anticipated financial impacts of the Business Combination, the satisfaction of the closing conditions to the Business

ability of Longview and HeartFlow prior to the Business Combination, and New HeartFlow following the Business Combination, to meet the
closing conditions in the Business Combination Agreement, including due to failure to obtain approval of the stockholders of Longview
and HeartFlow or certain regulatory approvals, or failure to satisfy other conditions to closing in the Business Combination Agreement;
(2) the occurrence of any event, change or other circumstances, including the outcome of any legal proceedings that may be instituted
against Longview and HeartFlow following the announcement of the Business Combination Agreement and the transactions contemplated therein,
that could give rise to the termination of the Business Combination Agreement or could otherwise cause the transactions contemplated therein
to fail to close; (3) the inability to obtain or maintain the listing of the combined company’s Class A common stock on
the New York Stock Exchange, as applicable, following the Business Combination; (4) the risk that the Business Combination disrupts
current plans and operations as a result of the announcement and consummation of the Business Combination; (5) the inability to recognize
the anticipated benefits of the Business Combination, which may be affected by, among other things, competition and the ability of the
combined company to grow and manage growth profitably and retain its key employees; (6) costs related to the Business Combination;
(7) changes in applicable laws or regulations or the healthcare industry; (8) the inability of the combined company to raise
financing in the future; (9) the success, cost and timing of HeartFlow’s and the combined company’s product development
activities, including market adoption of their current and future products; (10) the inability of HeartFlow or the combined company
to obtain and maintain regulatory approval for their current and future products, and any related restrictions and limitations of any
approved product; (11) the inability of HeartFlow or the combined company to build effective sales and marketing capabilities to support
the combined company’s growth strategy; (12) the inability of HeartFlow or the combined company to maintain HeartFlow’s existing
customer, license, and collaboration agreements, and arrangements with commercial and government payers; (13) changes in existing or anticipated
clinical guidelines, or the timing of adoption of positive clinical guidelines that support the use of HeartFlow’s and the combined
company’s products; (14) the inability of HeartFlow or the combined company to compete with other companies marketing or engaged
in the development of products that aid physicians in the evaluation and treatment of coronary artery disease; (15) the size and growth
potential of the markets for HeartFlow’s and the combined company’s products, and each of their ability to serve those markets,
either alone or in partnership with others; (16) the pricing of HeartFlow’s and the combined company’s products and reimbursement
for medical procedures conducted using HeartFlow’s and the combined company’s products; (17) HeartFlow’s and the combined
company’s estimates regarding expenses, future revenue, capital requirements and needs for additional financing; (18) HeartFlow’s
and the combined company’s financial performance; (19) the impact of COVID-19 on HeartFlow’s business and/or the ability of
the parties to complete the Business Combination; and (20) other risks and uncertainties indicated from time to time in the proxy statement/prospectus
relating to the Business Combination, including those under “Risk Factors” in the Registration Statement, and in Longview’s
other filings with the SEC.
Longview cautions that the foregoing list of factors is not exclusive.
Longview cautions investors not to place undue reliance upon any forward-looking statements, which speak only as of the date made. Longview
does not undertake or accept any obligation or undertaking to release publicly any updates or revisions to any forward-looking statements
to reflect any change in its expectations or any change in events, conditions or circumstances on which any such statement is based.
