statements made pursuant to the safe-harbor provisions of the Private Securities Litigation Reform Act of 1995. These forward-looking statements represent the Company&#8217;s expectations or beliefs concerning future events, including the timing of
the proposed Merger and other information relating to the proposed Merger. Forward-looking statements include information concerning possible or assumed future results of operations of the Company, the expected completion and timing of the proposed

statements are not forward-looking. Where, in any forward-looking statement, the Company expresses an expectation or belief as to future results, such expectation or belief is expressed in good faith and believed to be reasonable at the time such
forward-looking statement is made. However, these statements are not guarantees of future performance and involve certain risks, uncertainties and other factors beyond the Company&#8217;s control. Therefore, actual outcomes and results may differ
materially from what is expressed or forecast in the forward-looking statements.<I></I>&nbsp;These following important factors and uncertainties, among others, could cause actual results to differ materially from those described in the
forward-looking statements: (i)&nbsp;the risk that the Merger may not be completed in a timely manner or at all, which may adversely affect the Company&#8217;s business and the price of the Common Stock of the Company, (ii)&nbsp;the failure to
satisfy the conditions to the consummation of the Merger, including the adoption of the Merger Agreement by the stockholders of the Company and the receipt of regulatory approvals from various governmental entities (including any conditions,
limitations or restrictions placed on these approvals) and the risk that one or more governmental entities may deny approval, (iii)&nbsp;the occurrence of any event, change or other circumstance that could give rise to the termination of the Merger
Agreement, (iv)&nbsp;the risk that the Merger Agreement may be terminated in circumstances that require the Company to pay a termination fee, (v)&nbsp;the effect of the announcement or pendency of the Merger on the Company&#8217;s business
relationships, operating results and business generally, (vi)&nbsp;risks that the proposed Merger disrupts current plans and operations, (vii)&nbsp;risks related to diverting management&#8217;s attention from the Company&#8217;s ongoing business
operations, (viii)&nbsp;the outcome of any legal proceedings that may be instituted against the Company related to the Merger Agreement or the Merger, (ix)&nbsp;the Company&#8217;s ability to retain, hire and integrate skilled personnel including
the Company&#8217;s senior management team and maintain relationships with key business partners and customers, and others with whom it does business, in light of the proposed Merger, (x)&nbsp;unexpected costs, charges or expenses resulting from the
proposed Merger,&nbsp;(xi)&nbsp;the impact of adverse general and industry-specific economic and market conditions, (xii)&nbsp;risks caused by delays in upturns or downturns being reflected in the Company&#8217;s financial position and results of
operations, (xiii)&nbsp;risks that the benefits of the Merger are not realized when and as expected, (xiv)&nbsp;uncertainty as to timing of completion of the proposed Merger, and (xv)&nbsp;other factors described under the heading &#8220;Risk

PROS Holdings, Inc. (NYSE: PRO) (&#8220;PROS&#8221;), a leading provider of <FONT STYLE="white-space:nowrap">AI-powered</FONT> SaaS pricing and selling solutions, today announced the post-closing plans for PROS. Following the completion of Thoma
Bravo&#8217;s planned acquisition of PROS, which was announced on September&nbsp;22, 2025 and is expected to close in Q4 2025, Thoma Bravo intends to run the travel business of PROS as a platform investment while existing portfolio company Conga, a
leader for <FONT STYLE="white-space:nowrap">AI-powered</FONT> innovation in configure, price, quote (CPQ), contract lifecycle management (CLM) and document automation, will combine with the B2B business of PROS. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">&#8220;We are thrilled to be investing in PROS and excited by the opportunities ahead to grow the travel business,&#8221; said A.J. Rohde, a Senior Partner at
Thoma Bravo. &#8220;In the large and hyper-competitive airline and travel industry, there is increasing pressure to streamline pricing and selling systems to help customers grow and increase revenue. Trusted by airlines and travel companies

<P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">&#8220;This strategic plan will enable PROS to better serve customers through deep domain expertise and accelerate growth with focused innovation across both
the B2B and travel sectors,&#8221; said PROS CEO, Jeff Cotten. &#8220;Combining PROS&#8217; B2B business and Conga will unlock a broader, more powerful solution portfolio that expands on the offerings the business can deliver to customers and drives
greater value across every stage of their commercial operations. Meanwhile, with Thoma Bravo&#8217;s support, the travel business will be equipped to further invest in innovation, grow our airline and travel platform and fortify our position as a
market leader in this dynamic sector.&#8221; </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">&#8220;This is an exciting new growth stage for PROS and continues to build on the trust that our customers
have in PROS with greater agility and flexibility,&#8221; said Surain Adyanthaya, President of Global Industries at PROS. &#8220;With Thoma Bravo&#8217;s conviction in our travel business, we believe we are strongly positioned to help our customers
grow and continue to improve our operational efficiency in an <FONT STYLE="white-space:nowrap">AI-led</FONT> era,&#8221; said Ajay Damani, Executive Vice President of Engineering at PROS. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">Commenting on Conga&#8217;s planned combination with PROS&#8217; B2B business, Holden Spaht, a Managing Partner at Thoma Bravo, said: &#8220;We are excited to
combine Conga, our revenue lifecycle management platform, with PROS&#8217; AI-driven pricing optimization capabilities. The combination of these two market leaders addresses the increasing need for enterprises to dynamically price and quote complex
SKU bundles in the age of AI.&#8221; </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">Under the terms of PROS&#8217; agreement to be acquired by Thoma Bravo, at closing, PROS shareholders will receive
$23.25 per share in cash, representing a premium of approximately 41.7&nbsp;percent over PROS&#8217; closing share price on September&nbsp;19, 2025, the last full trading day prior to the transaction announcement, and a 53.2&nbsp;percent premium to
